-
-Oh - you are asking for a howto.
-
-	Step one.  Which DSPAM is right for you?
-
-The DSPAM project makes dspam part of the LDA (Local Delivery Agent).
-Pydspam puts dspam into the MTA (Mail Transfer Agent - sendmail with pymilter).
-
-The advantage of doing dspam in the LDA is that any aliasing has already been
-resolved.  You need only configure mailboxes.
-
-The advantage of doing dspam in the MTA is it can screen an entire 
-company as a gateway with multiple domains.  Unfortunately, this
-means you have to tell it about all the aliases that comprise each
-account.  (Also, pydspam is still uses dspam-2.6.5.2 - the Dspam API
-has changed for newer versions.)
-
-If the LDA is right for you, you'll want to use the official Dspam 
-package.  http://www.nuclearelephant.com/projects/dspam/
-
-If the MTA approach is what you want, then pydspam is what you want.
-
-In either case, you will still want pymilter to block forgeries, Windows 
-executables, etc.
-
-So, lets assume you want to install pymilter, and may or may not
-wish to install pydspam.
-
-	Step two.  Obtaining RPMS.
-
-For basic pymilter you'll need:
-
-python-2.4
-milter-0.8.10
-sendmail-8.13.x	(with milter support enabled)
-
-and for SPF you'll need:
-
-pydns-2.3.3-2.4
-pyspf-2.0.5-1.py24
-
-and for SRS you'll need:
-
-pysrs-0.30.11-1.py24
-
-I'm pretty sure you will want to have SPF and SRS available.
-
-	Step three.  Activate basic milter.
-
-Activate the basic milter and pysrs by editing /etc/mail/sendmail.mc and adding:
-
-define(`NO_SRS_FILE',`/etc/mail/no-srs-mailers')dnl
-dnl define(`NO_SRS_FROM_LOCAL')dnl
-HACK(`pysrs',`/var/run/milter/pysrs')dnl
-INPUT_MAIL_FILTER(`pythonfilter', `S=local:/var/run/milter/pythonsock, F=T, T=C:5m;S:20s;R:5m;E:5m')
-
-You can then "make sendmail.cf" and restart sendmail.
-
-Start milter and pysrs with "service milter start", "service pysrs start".
-
-Tail /var/log/milter/milter.log while SMTP clients connect to your
-sendmail instance.  This should show you what the milter is doing.
-
-By default, milter-0.8.10 rejects on SPF fail.
-
-	Step four.  Tweaking the basic config.
-
-Most pymilter configuration is in /etc/mail/pymilter.cfg.  To activate
-changes, "service milter restart".
-
-By default, milter scans attachments for executable extensions.  You can
-turn this off by setting banned_exts to the empty list.  There are options
-to scan ZIP attachments and rfc822 attachments.  When it finds a banned
-file type, milter saves the original message in /var/log/milter/save,
-and replaces the attachment with a plain text warning message.
-
-Configure hello_blacklist with your own helo name and domains - which
-you know cannot legitimately be used by external MTAs.
-
-Configure trusted_relay with your secondary MX servers, if any.  These
-should also run pymilter with similar policies.  (But this isn't
-needed for initial testing.)
-
-Configure internal_connect with subnets of your internal SMTP clients.
-Internal connections skip SPF testing and other policies.  You will
-likely need to set this to allow outgoing mail if you have
-an SPF policy already.
-
-Configure internal_domains with domains used by your internal SMTP clients.
-If they attempt to use any other domain, the attempt is blocked and the
-client is logged as a "zombie".  Conversely, any attempt by an external
-MTA to use one of your internal domains is treated as a forgery and
-blocked (a simplified form of local SPF).
-
-Adjust porn_words and spam_words - these block emails with a Subject
-containing the listed strings.  They can be empty to disable Subject
-string blocking.
-
-	Advanced SPF configuration.
-
-The sendmail access file, or another readonly database with that
-format, can be used for detail spf policy.  SPF access policy
-record are tagged with "SPF-{Result}:".  Results are
-Pass, Neutral, Softfail, Fail, PermError.  Currently supported
-policy keywords are OK, CBV, REJECT.  Currently, TempError always
-results in TEMPFAIL.
-
-The default policies are set in pymilter.cfg.  The defaults
-if none of the config options are set are as follows:
-
-SPF-Fail:	REJECT
-SPF-Softfail:	CBV
-SPF-Neutral:	OK
-SPF-PermError:	REJECT
-SPF-Pass:	OK
-
-The tag may be followed by a specific domain.  For instance, to
-require a Pass from aol.com:
-
-SPF-Neutral:aol.com	REJECT
-SPF-Softfail:aol.com	REJECT
-
-The CBV policy requires a valid HELO name.  If the EHLO name is 
-RFC2822 compliant, then a DSN is sent to the alleged sender.  The 
-template for the DSN is selected according to the SPF result:
-
-Fail:		fail.txt
-SoftFail:	softfail.txt
-Neutral:	neutral.txt
-PermError:	permerror.txt
-None:		strike3.txt
-
-An SPF-Pass is always accepted by the milter.  Domains can be blacklisted 
-via sendmail in the access file or via a RHS DNS blacklist.
-
-	To be continued.
-
-Forthcoming topics:
-
-SRS config
-
-
-pydspam config
-wiretap config

-The recent feature to let a REJECT policy for SPF None be overridden
-by whitelisting is working for CSI and CMS.  However, there could be
-a sender that we want to REJECT even when whitelisted - because they
-normally get a guessed PASS.  Need another policy name - or else just
-add them to local SPF so they won't ever get 'None'.
+Support smfi_negotiate and auto negotiate only those callbacks for which 
+Milter.Milter methods have been overridden.  (Python should be able to
+do that.)
 
-When policy is OK, do not use cbv_cache for blacklist.
-
-Add postmaster option or general rcpt list to dsn.  Can send dsn to
-user and postmaster on the same connection.
-
-Check ESMTP NOTIFY before sending real DSNs.  Just use CBV if DSNs are
-not wanted.
-
-Support CBV to local domains and cache results so that invalid users
-can be rejected without maintaining valid user lists.
-
-Now that we blacklist IPs for too many bad rcpts, delay SPF until RCPT TO.
-
-When content filtering is not installed, reject BLACKLISTed MFROM
-immediately.  There is no use waiting until EOM.
-
-Configuration is problematic when handling incoming, but not outgoing mail.
-The problem comes when alice@example.com sends mail to bill@example.com,
-and we are the MX for example.com, but alice is sending from some other
-MTA.  The mail is flagged external, so we don't list example.com in
-internal_domains (or we would get "spam from self").  But, if we try to do a
-CBV, we get "fraudulent MX", because the MX is ourself!  So we need to 
-avoid doing CBV on such domains.  Currently, we try to make sure the SPF
-policies don't do CBV.  The real solution is for users to use SMTP AUTH,
-but some of them are stubborn.
-
-We now don't check internal domains for incoming mail if there is an
-SPF record.
-
-On the other hand, if alice is sending internally, or with SMTP AUTH, she
-*does* need the domain to be in internal_domains.  The solution to that 
-is to use the new SMTP AUTH access configuration to specify which domains
-can be used by smtp AUTH (by user if desired).
-
-It would be cleaner if CBV would know which domains we have agreed to
-be MX for. Some ideas for external connections:
-
-a) check access file for To:example.com	RELAY
-b) check mailertable
-c) check mx_domains config list
-d) if there is an SPF record, don't check internal_domains
-   (let SPF block unauthorized machines)
-
-But that still doesn't handle the roaming user, who won't use SMTP
-AUTH, but sends through some hotel MTA.  Maybe we don't want to support
-him?
-
-When setting up pydspam, both sender and rcpt must resolve to dspam users
-for falsepositive recognition.  Usually, this means adding 
-honeypot@mail.example.com to alias list for honeypot in pymilter.cfg.
-This needs to be documented.  I was caught by it setting up a new site.
-
-Add signature (x-sig=AB7485f=TS) to Received-SPF, so it can be used
-to blacklist sources of delayed DSNs.
-
-rcpt-addr may let us know when a recipient is unknown.  That should count
-against reputation.
-
-Need to use wildcards in blacklist.log: *.madcowsrecord.net
-Need to exclude emails like !*-admin@example.com in whitelist_sender.
-Need to exclude robot users from autowhitelist.  Don't want to have to
-list all users, so implement something like !*-admin@bmsi.com,@bmsi.com.
-
-GOSSiP feedback from user training is ignored because UMIS has already been
-removed from queue.  Maybe keep UMIS in queue, and add method to 
-alter last feedback for ID.
-
-Generate DSNs according to RFC 3464
-
-Get temperror policy from access file.
-
-Reporting explanation for failure should show source if sender
-provided explanation.
-
-Bug in Auto-whitelist.  Recent Auto-whitelist doesn't override expired entry.
-
-SPF permerror diagnostics should include corrected mechanism.
-
-Delay SPF check until RCPT TO.  Cache result to avoid repeating
-for multiple RCPT.  This avoids overhead for invalid RCPT, and
-allows for per RCPT local policy.
-
-Check SPF for outgoing mail (including local policy for internal addresses).
-This could also solve the second part of the mail from relay problem below.
-
-Whitelisted senders from trusted relay get PROBATION.  Need to extracted
-SPF result from headers - and in the case of mail internal to relay
-(e.g. bmsi.com), supply 'pass' result.  
-
-Add auto-blacklisted senders to blacklist.log with timestamp.
-Add emails blacklisted via CBV so that they are remembered across milter
-restarts.
-
-Make all dictionaries work like honeypot.  Do not train as ham unless
-whitelisted.  Train on blacklisted messages, or spam feedback.  This
-can be called Train On Error.  Should be possible to startup
-with training on everything to get dictionary built fast, then switch
-to train on error to minimize labor.
-
-Allow unsigned DSNs from selected domains (that don't accept signed MFROM,
-e.g. verizon.net).
-
-Allow verified hostnames for trusted_relay.  E.g. HELO name that
-passes SPF.
-
-When do we get two hello calls?  STARTTLS is one reason.
-
-Option: accept mail from auto-whitelisted senders even with spf-fail,
-but do not update dspam.  This can be done for individual senders or domains 
-using the access file.
-
-pysrs: SRS doesn't get applied to proper recipients when there are
-multiple recipients.  This requires debugging cf scripts - yuk.
-
-auto_whitelist false_positives from quarantine - perhaps only when
-user selects special button (use special header to communicate
-that from dspamcgi.py to milter.)
-
-Use send_dsn.log for blacklist also.  AddrCache needs localpart
-wildcard (e.g. empty localpart).
-
-Quarantined mail is missing headers modified/added by milter after
-checking dspam.
-
-Send DSN for permerror before processing extended result.  An additional
-DSN may be sent based on extended result.  Send permerror DSN to
-postmaster@sending_domain.
-
-Rescind whitelist for banned extensions, in case sender is infected.
-
-Train honeypot on error only.
-
-Find rfc2822 policy for MFROM quoting.
-
-Support explicit errors for SPF policy in access file:
-SPF-Neutral:aol.com	ERROR:"550 AOL mail must get SPF PASS"
-
-Defer TEMPERROR in SPF evaluation - give precedence to security
-(only defer for PASS mechanisms).
-
-Create null config that does nothing - except maybe add Received-SPF
-headers.  Many admins would like to turn features on one at a time.
-
-Can't output messages with malformed rfc822 attachments.
-
-Move milter,Milter,mime,spf modules to pymilter
-milter package will have bms.py application
-
-Web admin interface
-message log for automated stats and blacklisting
-Skip dspam when SPF pass? NO
-Report 551 with rcpt on SPF fail?
-check spam keywords with character classes, e.g.
-	{a}=[a@ãä], {i}=[i1í], {e}=[eë], {o}=[o0ö]
-
-Implement RRS - a backdoor for non-SRS forwarders.  User lists non-SRS 
-forwarder accounts, and a util provides a special local alias for the
-user to give to the forwarder.  (Or user just adds arbitrary alias
-unique to that forwarder to a database.)  Alias only works for mail from that
-forwarder.  Milter gets forwarder domain from alias and uses it to
-SPF check forwarder.
-
-Framework for modular Python milter components within a single VM.
-Python milters can be already be composed through sendmail by running each in
-a separate process.  However, a significant amount of memory is wasted
-for each additional Python VM, and communication between milters
-is cumbersome (e.g., adding mail headers, writing external files).
-
-Copy incoming wiretap mail, even though sendmail alias works perfectly
-for the purpose, to avoid having to change two configs for a wiretap.
-
-Provide a way to reload milter.cfg without stopping/restarting milter.
-
-Allow selected Windows extensions for specific domains via milter.cfg
-
-Fix setup.py so that _FFR_QUARANTINE is automatically defined when
-available in libmilter.
-
-Keep separate ismodified flag for headers and body.  This is important
-when rejecting outgoing mail with viruses removed (so as not to
-embarrass yourself), and also removing Received headers with hidepath.
-
-Need a test module to feed sample messages to a milter though a live 
-sendmail and SMTP.  The mockup currently used is probably not very accurate,
-and doesn't test the threading code.
-
-DONE Table of sendmail macros for documentation.  In API docs on milter.org.
-
-DONE For selected domains, check rcpts via CBV before accepting mail.  Cache
-results.  This will kick out dictonary attacks against a mail domain
-behind a gateway sooner.
-
-DONE Convert DSN to REJECT unless sender gets SPF pass or best guess pass.  Make
-configurable by SPF result with NOTSPAM policy (reject or deliver without DSN).
-Maybe policy should be NODSN - still verify sender with CBV.
-
-DONE Add parseaddr test case for 'foo@bar.com <baz@barf.biz>'
-
-DONE Require signed MFROM for all incoming bounces when signing all outgoing
-mail - except from trusted relays.
-
-DONE Added Message-ID header to DSN with SRS signed sender.  When seen on
-incoming rfc ignorant failure message, blacklist sender.
-
-DONE Option to add Received-SPF header, but never reject on SPF.
-  I think the above will handle this.
-
-DONE Received-SPF header field should show identity that was checked.
-
-DONE When training with spam, REJECT after data so that mistakenly blacklisted
-senders at least get an error.
-
-DONE Milter won't start when it can't change permissions on *.lock to match
-*.log.  Should maybe ignore that error - the effect will be to set
-the permissions to default.
-
-DONE Milter won't start when a whitelist/blacklist file is missing.
-
-DONE Delayed failure detection should parse From header to find email address.
-
-DONE When bms.py can't find templates, it passes None to dsn.create_msg(),
-which uses local variable as backup, which no longer exist.  Do plain
-CBV in that case instead.
-
-DONE Find and use X-GOSSiP: header for SPAM: and FP: submissions.  Would need
-to keep tags longer.
-
-DONE Parse incoming 3464 DSNs for "Action: failed" to recognize delayed
-failures.  This works regardless of Subject.
-
-DONE Reports PROBATION even when rejecting message (works, but confusing in
-log).
-
-DONE Delayed_failure detection needs to handle multi-line header fields.  
-Also, delayed_failure should be recognized when addressed to
-postmaster@helodomain 
-
-DONE DSN for Permerror shows 'None' for error under some condition.
-
-DONE Allow blacklisted emails as well as domains in blacklist.log.  Use same
-data structure as autowhitelist.log.  
-
-DONE Backup copies for outgoing/incoming mail.
-
-DONE Don't match dynamic ptr in bestguess.
+Lookup exact RFC syntax of real name / email and make 
+Milter.utils.parse_addr() pass all unit tests.

-Title: Recent Changes
-
-<h2> Recent Changes </h2>
-
-<h3> 0.8.10 </h3>
-
-SRS rejections now log the recipient.  
-I have finally implemented plain CBV (no DSN).  The CBV policy
-will do a plain CBV from now on, and the DSN policy is required
-if you want to send a DSN.
-I started checking the MAIL FROM fullname (human readable part
-of an email) for porn keywords.  There is now a banned IP database.
-IPs are banned for too many bad MAIL FROMs or RCPT TOs, and remain banned
-for 7 days.
-
-<h3> 0.8.9 </h3>
-
-I use the <code>%ifarch</code> hack to build milter and milter-spf
-packages as noarch, while pymilter is built as native.
-
-I removed the spf dependency from dsn.py, so pymilter can be used without
-installing pyspf, and added a Milter.dns module to let python milters do
-general DNS lookups without loading pyspf.
-
-<h3> 0.8.8 </h3>
-
-Programs do not belong in the /var/log directory.  I moved the
-milter apps to /usr/lib/pymilter.  Since having the programs and
-data in the same directory is convenient for debugging, it will
-still use an executable present in the datadir.
-
-Several general utility classes and functions are now in the Milter package
-for possible use by other python milters.  In addition to the trivial example
-milter, a simple SPF only milter is included as a realistic example.
-
-The spec file now build 3 RPMs:
-
-<ul>
-<li> pymilter is the milter module and Milter package for use by all python
-     milters.
-<li> milter is the all-singing, all-dancing python milter application, with
-     supporting <code>/etc/init.d</code>, logrotate and other scripts.
-<li> milter-spf is the simple SPF only milter application.
-</ul>
-
-<h3> 0.8.7 </h3>
-
-The spf module has been moved to the 
-<a href="http://cheeseshop.python.org/pypi/pyspf">pyspf</a> package.
-Download <a href="http://sourceforge.net/project/showfiles.php?group_id=139894&package_id=191419">here</a>.
-
-<h3> 0.8.6 </h3>
-
-Python milter has been moved to 
-<a href="http://sourceforge.net/projects/pymilter/">pymilter Sourceforge
-project</a> for development and release downloads.
-
-<h3> 0.8.5 </h3>
-
-Release 0.8.5 fixes some build bugs reported by Stephen Figgins.  It
-fixes many small things, like not auto-whitelisting recipients of
-outgoing mail when the subject contains "autoreply:".  There is a 
-simple trusted forwarder implementation.  If you have more than
-2 or so forwarders, we will need a way to "compile" SPF records into an
-IP set and TTL for it to be efficient (like libspf2 does).
-
-<h3> GOSSiP </h3>
-An alpha release of <a href="pygossip.html">pygossip</a> has been commited to
-CVS, module pygossip. A version of the bms.py milter has been commited to CVS
-which supports calling GOSSiP to track domain reputation in a local database.
-
-<h3> New website design </h3>
-
-Hey, I'm no artist, so I just used the
-<a href="http://ht2html.sourceforge.net/">ht2html</a> package
-by <a href="http://barry.wooz.org/">Barry Warsaw</a>.  The mascot
-is by <a href="http://alphard.ethz.ch/hafner/lebl.htm">Christian Hafner</a>,
-or maybe his wife.  I chose Maxwell's daemon because it tirelessly
-and invisibly sorts molecules, just as milters sort mail.
-Christian has also provided a fun 
-<a href="http://alphard.ethz.ch/hafner/PPS/PPS2002/Maxwell/simulation.htm">
-simulation</a> that lets you try your hand at sorting molecules.
-
-<h3> 0.8.4 </h3>
-
-Release 0.8.4 makes configuring SPF policy via access.db actually work.
-The honeypot idea is enhanced by auto-whitelisting recipients of
-email sent from selected domains.  Whitelisted messages are then used
-to train the honeypot.  This makes the honeypot screener entirely self
-training.  The smfi_progress() API is now automatically supported when present.
-An optional idx parameter to milter.addheader() invokes smfi_insheader().
-
-<h3> 0.8.3 </h3>
-
-Release 0.8.3 uses the standard logging module, and supports configuring
-more detailed SPF policy via the sendmail access map.  SMTP AUTH connections
-are considered INTERNAL.  Preventing forgery between internal domains is
-just a matter of specifying the user-domain map - I'll define something
-for the next version.  We now send DSNs when mail is quarantined (rejecting
-if DSN fails) and for SPF syntax errors (PermError).  There is an
-experimental option to add a Sender header when it is missing and the From
-domain doesn't match the MAIL FROM domain.  Next release, we may start
-renaming and replacing an existing Sender header when neither it nor the
-From domain matches MAIL FROM.  Since bogus MAIL FROMs are rejected
-(to varying degrees depending on the configured SPF policy), and
-both Sender and From and displayed by default in many email clients,
-this provides some phishing protection without rejecting mail based
-on headers.
-
-<h3> 0.8.2 </h3>
-
-Release 0.8.2 has changes to <a href="http://openspf.net">SPF</a> to bring it
-in line with the newly official RFC.  It adds 
-<a href="http://ses.codeshare.ca/">SES</a>
-support (the original SES without body hash) for pysrs-0.30.10, and honeypot
-support for pydspam-1.1.9.  There is a new method in the base milter module.
-milter.set_exception_policy(i) lets you choose a policy of CONTINUE, REJECT, or
-TEMPFAIL (default) for untrapped exceptions encountered in a milter callback.
-
-<h3> 0.8.0 </h3>
-
-Release 0.8.0 is the first <a href="http://sourceforge.net/">Sourceforge</a>
-release.  It supports Python-2.4, and provides an option to accept mail
-that gets an SPF softfail or fails the 3 strikes rule, provided the
-alleged sender accepts a DSN explaining the problem.  Python-2.3 is
-no longer supported by the reworked mime.py module, although API changes
-could be backported.  There are too many incompatible changes to the
-python email package.
-
-<h3> Older Releases </h3>
-
-Release 0.7.2 tightens the authentication screws with a "3 strikes and
-you're out" policy.  A sender must have a valid PTR, HELO, or SPF record
-to send email.  Specific senders can be whitelisted using the
-"delegate" option in the spf configuration section by adding a
-default SPF record for them.  The PTR and HELO are required
-by RFC anyway, so this is not an unreasonable requirement.
-There is now a coherent policy for an SPF softfail result.  A softfail
-is accepted if there is a valid PTR or HELO, or if the domain
-is listed in the "accept_softfail" option of the spf configuration section.
-A neutral result is accepted by default if there is a valid PTR or
-HELO, (and the SPF record was not guessed), unless the domain is listed in the
-"reject_neutral" option.  Common forms of PTR records for dynamic IPs are
-recognized, and do not count as a valid PTR.  This does not prevent anyone
-from sending mail from a dynamic IP - they just need to configure a
-valid HELO name or publish an SPF record.
-<p>
-As SPF adoption continues to rise, forged spam is not getting through.  So
-spammers are publishing their SPF records as predicted.  The 0.7.2 RPM
-now provides the <code>rhsbl</code> sendmail hack so that spammer domains
-can be blacklisted.  With the RPM installed, add a line like the following
-to your <code>sendmail.mc</code>.
-<pre>
-HACK(rhsbl,`blackholes.example.com',"550 Rejected: " $&{RHS} " has been spamming our customers.")dnl
-</pre>
-<p>
-Of course, spammers are now starting to register
-throwaway domains.  The next thing we need is a custom DNS server,
-in Python, that
-can recognize patterns.  For instance, one spammer registers ded304.com,
-ded305.com, ded306.com, etc.  We also need the custom DNS server to
-let SPF classic clients check SES (which will be part of pysrs).  
-The <a href="http://twistedmatrix.com/products/twisted">Twisted Python</a>
-framework provides a custom DNS server - but I
-would like a smaller implementation for our use.
-<p>
-The RPM for release 0.7.0 moves the config file and socket locations to
-/etc/mail and /var/run/milter respectively.  We now parse Microsoft CID records
-- but only hotmail.com uses them.  They seem to have applied for a patent on
-the brilliant idea of examining the mail headers to see who the message is
-from.  We aren't doing that here, so not to worry - but I am not a lawyer, so
-if you are worried, change spf.py around line 626 to return None instead of
-calling CIDParser().  There is a new option to reject mail with no PTR
-and no SPF.
-<p>
-Microsoft is pushing an anti-opensource license for their pending patent
-along with their sender-ID proposal before the IETF.
-It is royalty free - but requires anyone distributing a binary they've
-compiled from source to sign a license agreement.  The Apache Software
-Foundation <a
-href="http://www.apache.org/foundation/docs/sender-id-position.html"> explains
-the problem with sender-ID</a>, and Debian <a

-Release 0.6.0 offers a simple application of dspam I call "header triage",
-which rejects messages with spammy headers.  
-To use header triage, you must have <a href="dspam.html">DSPAM</a> installed,
-and select a dictionary that is well moderated by someone who gets
-lots of spam.  That dictionary can be used to block spam that is 
-obvious from the headers (e.g. X-Mailer and Subject) before it ties
-up any more resources.  I have yet to see any false positives from this
-approach (check the milter log), but if there are, the sender will
-get a REJECT with the message "Your message looks spammy."

-<h3> <a name="compiling">Compiling Python Milter </a> </h3>
-
-<li> Q. I have tried to download the current milter code and my virus scan
-traps several viruses in the download.
-<p>  A. The milter source includes a number of deactivated viruses in
-the test directory.  All but the first and last lines of the base64
-encoded virus data has been removed.  I suppose I should randomize
-the first and last lines as well, since pymilter just deletes executables,
-and doesn't look for signatures.
-<li> Q. I have installed sendmail from source, but Python milter won't
-compile.
-<p>  A. Even though libmilter is officially supported in sendmail-8.12, 
-you need to build and install it in separate steps.  Take a look
-at the <a href="/aix/sendmail12.spec">RPM spec file</a> for sendmail-8.12.  
-The %prep section shows you how to create
-a site.config.m4 that enables MILTER.  The %build section shows you how
-to build libmilter in a separate invocation of make.  The %install section
-shows you how to install libmilter with a separate invocation of make.
-<p>
-
-<li> Q. Why is mfapi.h not found when I try to compile Python milter on
-RedHat 7.2?
-<p>  A. RedHat forgot to include the header in the RPM.  See the
-<a href="requirements.html#rh72">RedHat 7.2 requirements</a>.
-<p>
-<li> Q. Python milter compiles ok, but I get an error like this when
-	I try to import the milter module:
-<pre>
-ImportError: /usr/lib/python2.4/site-packages/milter.so: undefined symbol: smfi_setmlreply
-</pre>
-<p>  A. Your libmilter.a is from sendmail-8.12 or earlier.  You need
-	sendmail-8.13 or later to support setmlreply.  You can disable
-	setmlreply by changing setup.py.  Change:
-<pre>
-            define_macros = [ ('MAX_ML_REPLY',32) ]
-</pre>
-in setup.py to
-<pre>
-            define_macros = [ ('MAX_ML_REPLY',1) ]
-</pre>
-
-<h3> <a name="running">Running Python Milter </a></h3>
-
-<li> Q. The sample.py milter prints a message, then just sits there.
-<pre>
-To use this with sendmail, add the following to sendmail.cf:
-
-O InputMailFilters=pythonfilter
-Xpythonfilter,        S=local:inet:1030@localhost
-
-See the sendmail README for libmilter.
-sample  milter startup
-</pre>
-<p>  A. You need to tell sendmail to connect to your milter.  The
-sample milter tells you what to add to your sendmail.cf to tell
-sendmail to use the milter.  You can also add an INPUT_MAIL_FILTER
-macro to your sendmail.mc file and rebuild sendmail.cf - see the sendmail
-README for milters.
-<p>
-
-<li> Q. I've configured sendmail properly, but still nothing happens
-when I send myself mail!
-<p>  A. Sendmail only milters SMTP mail.  Local mail is not miltered.
-You can pipe a raw message through sendmail to test your milter:
-<pre>
-$ cat rawtextmsg | sendmail myname@my.full.domain
-</pre>
-Now check your milter log.
-<p>
-
-<li> Q. Why do I get this ImportError exception?
-<pre>
-File "mime.py", line 370, in ?
-    from sgmllib import declstringlit, declname
-    ImportError: cannot import name declstringlit
-</pre>
-<p>  A. <code>declstringlit</code> is not provided by sgmllib in all versions
-of python.  For instance, python-2.2 does not have it.  Upgrade to
-milter-0.4.5 or later to remove this dependency.
-<p>
-
-<li> Q. Why do I get <code>milter.error: cannot add recipient</code>?
-<pre>
-</pre>
-<p>  A. You must tell libmilter how you might mutate the message with
-<code>set_flags()</code> before calling <code>runmilter()</code>.  For
-instance, <code>Milter.set_flags(Milter.ADDRCPT)</code>.  You must add together
-all of <code>ADDHDRS, CHGBODY, ADDRCPT, DELRCPT, CHGHDRS</code> that apply.
-<p> NOTE - recent versions default flags to enabling all features.  You
-must now call <code>set_flags()</code> if you wish to disable features for
-efficiency.
-<p>
-
-<li> Q. Why does sendmail sometimes print something like:
-"...write(D) returned -1, expected 5: Broken pipe"
-in the sendmail log?
-<p>  A. Libmilter expects "rcpt to" shortly after getting "mail from".
-"Shortly" is defined by the timeout parameter you passed to
-<code>Milter.runmilter()
-</code> or <code>milter.settimeout()</code>.  If the timeout is 10 seconds,
-and looking up the first recipient in DNS takes more than
-10 seconds, libmilter will give up and break the connection.  
-<code>Milter.runmilter()</code> defaulted to 10 seconds in 0.3.4.  In 0.3.5
-it will keep the libmilter default of 2 hours.
-<p>
-
-<li> Q. Why does milter block messages with big5 encoding?  What if I
-want to receive them?
-<p>  A. sample.py is a sample.  It is supposed to be easily modified
-for your specific needs.  We will of course continue to move generic
-code out of the sample as the project evolves.  Think of sample.py as
-an active config file.
-<p>
-If you are running bms.py, then the block_chinese option in 
-<code>/etc/mail/pymilter.cfg</code> controls this feature.
-<p>
-
-<li> Q. Why does sendmail coredump with milters on OpenBSD?
-<p>  A. Sendmail has a problem with unix sockets on old versions of OpenBSD.
-OpenBSD users report that this problem has been fixed, so upgrading
-OpenBSD will fix this.  Otherwise, you can
-use an internet domain socket instead.  For example, in
-<code>sendmail.cf</code> use
-<pre>
-Xpythonfilter, S=inet:1234@localhost
-</pre>
-and change sample.py accordingly.
-<p>
-
-<li> Q. How can I change the bounce message for an invalid recipient?
-I can only change the recipient in the eom callback, but the eom callback
-is never called when the recipient is invalid!
-<p>  A. Configure sendmail to use virtusertable, and send all unknown
-addresses to /dev/null.  For example,
-<h4>/etc/mail/virtusertable</h4>
-<pre>
-@mycorp.com	dev-null
-dan@mycorp.com	dan
-sally@mycorp.com	sally
-</pre>
-<h4>/etc/aliases</h4>
-<pre>
-dev-null:	/dev/null
-</pre>
-Now your milter will get to the eom callback, and can change the
-envelope recipient at will.  Thanks to Dredd at 
-<a href=http://www.milter.org/>milter.org</a> for this solution.
-<p>
-
-<li> Q. I am having trouble with the setreply method.  It always outputs
-	"milter.error: cannot set reply".
-<p>  A. Check the sendmail log for errors.  If sendmail is getting
-milter timeouts, then your milter is taking too long and sendmail gave
-up waiting.  You can adjust the timeouts in your sendmail config.  Here
-is a milter declaration for sendmail.cf with all timeouts specified:
-<pre>
-Xpythonfilter, S=local:/var/log/milter/pythonsock, F=T, T=C:5m;S:20s;R:60s;E:5m
-</pre>
-<li> Q. There is a Python traceback in the log file!  What happened to
-	my email?
-<p>  A. By default, when the milter fails with an untrapped exception, a
-TEMPFAIL result (451) is returned to the sender.  The sender will then retry
-every hour or so for several days.  Hopefully, someone will notice the 
-traceback, and workaround or fix the problem.  Beginning with milter-0.8.2,
-you can call <code>milter.set_exception_policy(milter.CONTINUE)</code>
-to cause an untrapped exception to continue processing with the
-next callback or milter instead.  For
-completeness, you can also set the exception policy to
-<code>milter.REJECT</code>.
-
-<li> Q. I read some notes such as "Check valid domains allowed by internal
-	senders to detect PCs infected with spam trojans." but could not
-	understand the idea. Could you clarify the content ?
-
-<p>  A. The <code>internal_domains</code> configuration specifies which
-MAIL FROM domains are used by internal connections.  If an internal
-PC tries to use some other domain, it is assumed to be a "Zombie".
-<p>
-Here is a sample log line:
-<pre>
-2005Jun22 12:01:04 [12430] REJECT: zombie PC at  192.168.100.171  sending MAIL FROM  debby@fedex.com
-</pre>
-No, fedex.com does not use pymilter, and there is no one named debby at my
-client.  But the idiot using the PC at 192.168.100.171 has downloaded and
-installed some stupid weatherbar/hotbar/aquariumscreensaver that is actually a
-spam bot.
-<p>
-The <code>internal_domains</code> option is simplistic, it assumes all
-valid senders of the domains are internal.  SPF provides a much more general
-check of IP and MAIL FROM for external email.  Pymilter should soon
-have a local policy feature for more general checking of internal mail.
-<li> Q. <code>mail_archive</code> isn't working.  Or I don't understand how
-	it's suppose to work.  I have
-	<code>mail_archive = /var/mail/mail_archive</code>
-	in <code>pymilter.cfg</code> but nothing ever gets dumped into
-	<code>/var/mail/mail_archive</code>.
-<p>  A. The 'mail' user needs to have write access.  Permission failures
-	should be logged as a traceback in milter.log if it doesn't.
-
-<h3> <a name="spf">Using SPF </a></h3>
-
-<li> Q. So how do I use the SPF support?  The sample.py milter doesn't seem
-        to use it.
-<p>  A. The bms.py milter supports spf.  The RedHat RPMs will set almost
-everything up for you.  For other systems:
-<ol type=i>
-<li> Arrange to run bms.py in the background (as a service perhaps) and
-     redirect output and errors to a logfile.  For instance, on AIX you'll want
-     to use SRC (System Resource Controller).  
-<li> Copy pymilter.cfg to the /etc/mail or the directory you run bms.py in,
-     and edit it.  The comments should explain the options. 
-<li> Start bms.py in the background as arranged.
-<li> Add Xpythonfilter to sendmail.cf or add an INPUT_MAIL_FILTER to
-     sendmail.mc.  Regen sendmail.cf if you use sendmail.mc and restart 
-     sendmail.
-<li> Arrange to rotate log files and remove old defang files in 
-     <code>tempdir</code>.  The RedHat RPM uses <code>logrotate</code> for
-     logfiles and a simple cron script using <code>find</code> to clean
-     <code>tempdir</code>.
-</ol>
-	In CVS, there is <code>spfmilter.py</code>.  Run that as a service,
-	and it does just SPF.  It uses the sendmail <code>access</code>
-	file to configure SPF responses just like <code>bms.py</code>, but
-	supports only REJECT and OK.
-<li> Q. The SPF DSN is sent at least once for domains that don't publish a SPF.
-	How do I stop this behavior?
-<p>  A. The SPF response is controlled by <code>/etc/mail/access</code>
-	(actually the file you specify with <code>access_file</code> in
-	the <code>[spf]</code> section of <code>pymilter.cfg</code>).  
-	Responses are OK, CBV, and REJECT.  CBV sends the DSN.
-<p>
-You can change the defaults.  For instance, I have:
-<pre>
-SPF-None:	REJECT
-SPF-Neutral:	CBV
-SPF-Softfail:	CBV
-SPF-Permerror:	CBV
-</pre>
-I have best_guess = 1, so SPF none is converted to PASS/NEUTRAL for policy
-lookup, and 3 strikes (no PTR, no HELO, no SPF) becomes "SPF NONE" for local
-policy purposes (the Received-SPF header always shows the official SPF
-result.)
-<p>
-You can change the default for specific domains:
-<pre>
-# these guys aren't going to pay attention to CBVs anyway...
-SPF-None:cia.gov	REJECT
-SPF-None:fbi.gov	REJECT
-SPF-Neutral:aol.com	REJECT
-SPF-Softfail:ebay.com	REJECT
-</pre>
-
-<h3> <a name="srs">Using SRS </a></h3>
-
-<li> Q. The SRS part doesn't seem to work as whenever I try to start
-	<code>/etc/init.d/pysrs</code>, I get this in
-	<code>/var/log/milter/pysrs.log</code>:
-<pre>
-ConfigParser.NoOptionError: No option 'fwdomain' in section: 'srs'
-</pre>
-<p>  A. You need to specify the forward domain - i.e. the domain you want
-	SRS to rewrite stuff too.
-<p>
-For instance, I have:
-<pre>
-# sample SRS configuration
-[srs]
-secret = don't you wish
-maxage = 8
-hashlength = 5
-;database=/var/log/milter/srs.db
-fwdomain = bmsi.com
-sign=bmsi.com,mail.bmsi.com,gathman.org
-srs=bmsaix.bmsi.com,bmsred.bmsi.com,stl.gathman.org,bampa.gathman.org
-</pre>
-The <code>sign</code> is for local domains which are signed.
-The <code>srs</code> list is for other domains which you are relaying,
-and which need to have SRS checked/undone for bounces.

+## @mainpage Writing Milters in Python
+#
+# 
+# At the lowest level, the <code>milter</code> module provides a thin wrapper
+# around the <a href="https://www.milter.org/developers/api/index"> sendmail
+# libmilter API</a>.  This API lets you register callbacks for a number of
+# events in the process of sendmail receiving a message via SMTP.  These
+# events include the initial connection from a MTA, the envelope sender and
+# recipients, the top level mail headers, and the message body.  There are
+# options to mangle all of these components of the message as it passes through
+# the milter.
+# 
+# At the next level, the <code>Milter</code> module (note the case difference)
+# provides a Python friendly object oriented wrapper for the low level API.  To
+# use the Milter module, an application registers a 'factory' to create an
+# object for each connection from a MTA to sendmail.  These connection objects
+# must provide methods corresponding to the libmilter callback events.
+# 
+# Each event method returns a code to tell sendmail whether to proceed with

-
-<h3><a name=overview>Overview</a></h3>
-
-This package provides a robust toolkit for Python <a
-href="#milter">milters</a>, and the beginnings of a general purpose mail
-filtering system written in Python.
-<p>
-At the lowest level, the 'milter' module provides a thin wrapper around the
-<a href="https://www.milter.org/developers/api/index">
-sendmail libmilter API</a>.  This API lets you register callbacks for 
-a number of events in the
-<a href="http://www.cs.concordia.ca/~group/fig/public/email/relay/milter+ruleset-checks.html">process of sendmail receiving a message via SMTP</a>.  
-These events include the initial connection from a MTA,
-the envelope sender and recipients, the top level mail headers, and
-the message body.  There are options to mangle all of these components
-of the message as it passes through the milter.
-<p>
-At the next level, the 'Milter' module (note the case difference) provides a
-Python friendly object oriented wrapper for the low level API.  To use the
-Milter module, an application registers a 'factory' to create an object
-for each connection from a MTA to sendmail.  These connection objects
-must provide methods corresponding to the libmilter callback events.
-<p>
-Each event method returns a code to tell sendmail whether to proceed
-with processing the message.  This is a big advantage of milters over
-other mail filtering systems.  Unwanted mail can be stopped in its
-tracks at the earliest possible point.
-<p>
-The Milter.Milter class provides default implementations for event
-methods that
-do nothing, and also provides wrappers for the libmilter methods to mutate
-the message.
-<p>
-The 'spf' module provides an implementation of <a href="http://openspf.com">
-SPF</a> useful for detecting email forgery.
-<p>
-The 'mime' module provides a wrapper for the Python email package that
-fixes some bugs, and simplifies modifying selected parts of a MIME message.
-<p>
-Finally, the bms.py application is both a sample of how to use the
-Milter and spf modules, and the beginnings of a general purpose SPAM filtering,
-wiretapping, SPF checking, and Win32 virus protecting milter.  It can
-make use of the <a href="pysrs.html">pysrs</a> package when available for
-SRS/SES checking and the <a href="dspam.html">pydspam</a> package for Bayesian
-content filtering.  SPF checking
-requires <a href="http://pydns.sourceforge.net/">
-pydns</a>.  Configuration documentation is currently included as comments
-in the <a href="milter.cfg">sample config file</a> for the bms.py milter.
-See also the <a href="HOWTO">HOWTO</a> and <a href="logmsgs.html">
-Milter Log Message Tags</a>.
-<p>
-Python milter is under GPL.  The authors can probably be convinced to
-change this to LGPL if needed.
-
-<h3>What is a <a name="milter">milter</a>?</h3>
-
-Milters can run on the same machine as sendmail, or another machine.  The
-milter can even run with a different operating system or processor than
-sendmail.
-Sendmail talks to the milter via a local or internet socket.
-Sendmail keeps the
-milter informed of events as it processes a mail connection.  At any 
-point, the milter can cut the conversation short by telling sendmail
-to ACCEPT, REJECT, or DISCARD the message.  After receiving a complete
-message from sendmail, the milter can again REJECT or DISCARD it, but it
-can also ACCEPT it with changes to the headers or body.
-
-<h3> What can you do with a milter? </h3>
-
-<menu>
-<li> A milter can DISCARD or REJECT spam based based on algorithms scripted
-in python rather than sendmail's cryptic "cf" language.
-<li> A milter can alter or remove attachments from mail that are poisonous to
-Windows.
-<li> A milter can scan for viruses and clean them when detected.
-<li> A milter scans outgoing as well as incoming mail.
-<li> A milter can add and delete recipients to forward or secretly
-copy mail.
-<li> For more ideas, check the <a href="//www.milter.org">Milter Web Page</a>.
-</menu>
-
-<a href="https://www.milter.org/developers/api/index">
-Documentation</a> for the C API is provided with sendmail.  Miltermodule
-provides a thin python wrapper for the C API.  Milter.py provides a simple
-OO wrapper on top of that.
-<p>
-The Python milter package includes a sample milter that replaces dangerous 
-attachments with a warning message, discards mail addressed to
-MAILER-DAEMON, and demonstrates several SPAM abatement strategies.  
-The MimeMessage class to do this used to be based on the
-<code>mimetools</code> and <code>multifile</code> standard python packages.  
-As of milter version 0.6.0, it is based on the email standard
-python packages, which were derived from the 
-<a href="http://sourceforge.net/projects/mimelib">mimelib</a> project.
-The MimeMessage class patches several bugs in the email package,
-and provides some backward compatibility.
-
-<p>
-The "defang" function of the sample milter was inspired by
-<a href="http://www.roaringpenguin.com/mimedefang/">MIMEDefang</a>,
-a Perl milter with flexible attachment processing options.  The latest
-version of MIMEDefang uses an apache style process pool to avoid reloading
-the Perl interpreter for each message.  This makes it fast enough for
-production without using Perl threading.
-<p>
-<a href="http://sourceforge.net/projects/mailchecker">mailchecker</a> is
-a Python project to provide flexible attachment processing for mail.  I
-will be looking at plugging mailchecker into a milter.
-<p>
-<a href="http://software.libertine.org/tmda/">TMDA</a> is a Python project
-to require confirmation the first time someone tries to send to your
-mailbox.  This would be a nice feature to have in a milter.
-<p>
-There is also a <a href="http://www.milter.org/">Milter community website</a>
-where milter software and gory details of the API are discussed.
-
-<h3> Is a milter written in python efficient? </h3>
-
-The python milter process is multi-threaded and startup cost is incurred
-only once.  This is much more efficient than some implementations that
-start a new interpreter for each connection.  Testing in a production
-environment did not use a significant percentage of the CPU.  Furthermore,
-python is easily extended in C for any step requiring expensive CPU
-processing.
-<p>
-For example, the HTML parsing feature to remove scripts from HTML attachments
-is rather CPU intensive in pure python.  Using the C replacement for sgmllib
-greatly speeds things up.
-
-<h3> Goals </h3>
-
-<menu>
-<li> Implement RRS - a backdoor for non-SRS forwarders.  User lists non-SRS 
-     forwarder accounts (perhaps in <code>~/.forwarders</code>), and a util
-     provides a special local alias for the user to give to the forwarder.
-     Alias only works for mail from that forwarder.  Milter gets forwarder
-     domain from alias and uses it to SPF check forwarder.  Requires
-     milter to have read access to <code>~/.forwarders</code> or else
-     a way for user to submit entries to milter database.
-<li> The bms.py milter has too many features.  Create a framework where
-     numerous small feature modules can be plugged together in the
-     configuration.
-<li> Create a pure python substitute for miltermodule and libmilter that
-     implements the <a
-href="http://www.duh.org/cvsweb.cgi/~checkout~/pmilter/doc/milter-protocol.txt?rev=1">
-     libmilter protocol</a> in python. 
-<li> Find or write a faster implementation of sgmllib.  The 
-     <a href="http://www.effbot.org/zone/sgmlop-index.htm">sgmlop package</a>
-     is not very compatible with 
-     <a href="http://www.python.org/doc/2.1.3/lib/module-sgmllib.html">
-     Python-2.1 sgmllib</a>, but it is a start, and is supported in
-     milter-0.4.5 or later.
-<li> Implement all or most of the features of 
-     <a href="http://www.roaringpenguin.com/mimedefang/">MIMEDefang</a>.
-<li> Follow the official <a href="http://www.python.org/peps/pep-0008.html">
-     Python coding standards</a> more closely.
-<li> Make unit test code more like other python modules.
-</menu>
-
-<h3> Confirmed Installations </h3>
-
-Please <a href="mailto:%73%74%75%61%72%74%40%62%6D%73%69%2E%63%6F%6D">email</a>
-me if you do <i>not</i> successfully install milter.  The confirmed
-installations are too numerous to list at this point.
-
-<h2> Enough Already! </h2>
-
-Nearly a dozen people have emailed me begging for a feature to copy
-outgoing and/or incoming mail to a backup directory by user.  Ok, it
-looks like this is a most requested feature for 0.5.6.  In the meantime,
-here are some things to consider:
-<ul>
-<li> If you want to equivalent of a Bcc added to each message, this
-is very easy to do in the python code for bms.py.   See below.
-<li> If you want to copy to a file in a directory (thus avoiding having to
-set up aliases), this is slightly more involved.  The bms.py milter already
-copies the message to a temporary file for use in replacing the message body
-when banned attachments are found.  You have to open a file, and copy the
-Mesage object to it in eom().
-<li> Finally, you are probably aware that most email clients already
-keep a copy of outgoing mail?  Presumably there is a good reason for
-keeping another copy on the server.
-</ul>
-<p>
-To Bcc a message, call <code>self.add_recipient(rcpt)</code> in envfrom after
-determining whether you want to copy (e.g. whether the sender is local).  For
-example,
-<pre>
-  def envfrom(...
-    ...
-    if len(t) == 2:
-      self.rejectvirus = t[1] in reject_virus_from
-      if t[0] in wiretap_users.get(t[1],()):
-	self.add_recipient(wiretap_dest)
-      if t[1] == 'mydomain.com':
-        self.add_recipient('&lt;copy-%s&gt;' % t[0])
-      ...
-</pre>
-<p>
-To make this a generic feature requires thinking about how the configuration
-would look.  Feel free to make specific suggestions about config file
-entries.  Be sure to handle both Bcc and file copies, and designating what
-mail should be copied.  How should "outgoing" be defined?  Implementing it is
-easy once the configuration is designed.

-Title: Python Milter Mail Policy
-
-<h1> Python Milter Mail Policy </h1>
-
-These are the policies implemented by the <code>bms.py</code> milter
-application.  The milter and Milter modules do not implement any policies
-by themselves.  
-
-<h3> Classify connection </h3>
-
-When the SMTP client connects, the connection IP address is
-saved for later verification, and the connection
-is classified as INTERNAL or EXTERNAL by matching the ip
-address against the <code>internal_connect</code> configuration.
-IP addresses with no PTR, and PTR names that look like
-the kind assigned to dynamic IPs (as determined by a heuristic
-algorithm) are flagged as DYNAMIC.  IPs that match the
-<code>trusted_relay</code> configuration are flagged as TRUSTED.
-<p>
-Examples from the log file (<i>not</i> the SMTP error message returned):
-<pre>
-2005Jul29 13:56:53 [71207] connect from p50863492.dip0.t-ipconnect.de at ('80.134.52.146', 1858) EXTERNAL DYN
-2005Jul29 18:10:15 [74511] connect from foopub at ('1.2.3.4', 46513) EXTERNAL TRUSTED
-2005Jul29 14:41:00 [71805] connect from foobar at ('192.168.0.1', 41205) INTERNAL
-2005Jul29 14:41:15 [71806] connect from cncln.online.ln.cn at ('218.25.240.137', 35992) EXTERNAL
-</pre>
-<p>
-Certain obviously evil PTR names are blocked at this point:
-"localhost" (when IP is not 127.*) and ".".
-<pre>
-2005Jul29 14:49:50 [71918] connect from localhost at ('221.132.0.6', 50507) EXTERNAL
-2005Jul29 14:49:50 [71918] REJECT: PTR is localhost
-</pre>
-
-<h3> HELO Check </h3>
-
-The HELO name provided by the client is saved for later verification
-(for example by SPF).  We could validate the HELO at this point
-by verifying that an A record for the HELO name matches the connect ip.
-However, currently we only block certain obvious problems.  
-HELO names that look like an IP4 address 
-and ones that match the <code>hello_blacklist</code> configuration
-are immediately rejected.  The hello_blacklist typically contains
-the current MTAs own HELO name or email domains.
-Clients that attempt to skip HELO are immediately rejected.
-<pre>
-2005Jul29 18:10:15 [74512] hello from example.com
-2005Jul29 18:10:15 [74512] REJECT: spam from self: example.com
-2005Jul29 18:17:09 [74581] hello from 80.191.244.69
-2005Jul29 18:17:09 [74581] REJECT: numeric hello name: 80.191.244.69
-</pre>
-
-<h3> MAIL FROM Check </h3>
-
-Before calling our milter, sendmail checks a DNS blacklist to 
-block banned sender domains.  We never see a blocked domain.
-<p>
-The MAIL FROM address is saved for possible use by the smart-alias
-feature.  First, the <code>internal_domains</code> is used for
-a simple screening if defined.  If the MAIL FROM for an INTERNAL connection 
-is NOT in <code>internal_domains</code>, then it is rejected (the
-PC is most likely infected and attempting to send out spam).
-If the MAIL FROM for an EXTERNAL connection IS in
-<code>internal_domains</code>, then the message is immediately rejected.
-This is quick and effective for most small company MTAs.  For more
-complex mail networks, it is too simplistic, and should not be defined.
-SPF will handle the complex cases.
-
-<h4> wiretap </h4>
-
-The wiretap feature can screen and/or monitor mail to/from certain
-users.  If the MAIL FROM is being wiretapped, the recipients are
-altered accordingly.
-
-<!--table-stop-->
-
-<h2> SPF check </h2>
-
-The MAIL FROM, connect IP, and HELO name are checked against
-any SPF records published via DNS for the alleged sender (MAIL FROM)
-to determine the official SPF policy result.
-The offical SPF result is then logged in the Received-SPF header field,
-but certain results are subjected to further processing to create
-an effective result for policy purposes.
-<p>
-If the official result is 'none', we try to turn it into an effective result of
-'pass' or 'fail'.  First, we check for a local substitute SPF record
-under the domain defined in the <code>[spf]delegate</code> configuration.  
-It is often useful to add local SPF records for correspondents that are
-too clueless to add their own.  If there is no local substitute, we use a "best
-guess" SPF record of "v=spf1 a/24 mx/24 ptr" for MAIL FROM or "v=spf1 a/24
-mx/24" for HELO.  In addition, a HELO that is a subdomain of MAIL FROM and
-resolves to the connect IP results in an effective result of 'pass'.
-<p>
-If there is no local SPF record, and the effective result is still not
-'pass', we check for either a valid HELO name or a valid PTR record for
-the connect IP.  A valid HELO or PTR cannot look like a dynamic name
-as determined by the heuristic in <code>Milter.dynip</code>.
-<p>
-If HELO has an SPF record, and the result is anything but pass, we reject
-the connection:
-<pre>
-2005Jul30 19:45:16 [93991] connect from [221.200.41.54] at ('221.200.41.54', 3581) EXTERNAL DYN
-2005Jul30 19:45:18 [93991] hello from adelphia.net
-2005Jul30 19:45:19 [93991] mail from <wendy.stubbsua@link-it.com> ()
-2005Jul30 19:45:19 [93991] REJECT: hello SPF: fail 550 access denied
-</pre>
-Note that HELO does not have any forwarding issues like MAIL FROM, and so
-any result other than 'pass' or 'none' should be treated like 'fail'.
-<p>
-Only if nothing about the SMTP envelope can be validated does the effective
-result remain 'none.  I call this the "3 strikes" rule.
-<p>
-If the official result is 'permerror' (a syntax error in the sender's
-policy), we use the 'lax' option in pyspf to try various heuristics to guess 
-what they really meant.  For instance, the invalid mechanism "ip:1.2.3.4" is
-treated as "ip4:1.2.3.4".  The result of lax processing is then used
-as the effective result for policy purposes.
-<p>
-With an effective SPF result in hand, we consult the sendmail access
-database to find our receiver policy for the sender.  
-
-<table border=1>
-<tr><th>REJECT</th><td>
-Reject the sender with a 550 5.7.1 SMTP code.  The SMTP rejection
-includes a detailed description of the problem.
-</td></tr>
-<tr><th>CBV</th><td>
-Do a Call Back Validation by connecting to an MX of the sender

-wrong person.  However, a SoftFail result is requesting such feedback
-for debugging and a PermError result needs to be fixed by the sender ASAP
-whether forged or not.  DSN results are cached so that senders are
-annoyed only weekly.

-</table>
-
-<h3> SPF policy syntax </h3>
-
-First, the full sender is checked:
-<pre>
-SPF-Fail:abeb@adelphia.net     DSN
-</pre>
-This says to accept mail from that adelphia.net user despite the
-SPF fail, but only after annoying them with a DSN about their ISP's broken
-policy. 
-<p>
-If there is no match on the full sender, the domain is checked:
-<pre>
-SPF-Neutral:aol.com     REJECT
-</pre>
-This says to reject mail from AOL with an SPF result of neutral.
-This means AOL users can't use their AOL address with another mail service
-to send us mail.  This is good because the other mail service is 
-likely a badly configured greeting card site or a virus.
-<p>
-Finally, a default policy for the result is checked.  While there are program
-defaults, you should have defaults in the access database for SPF results:
-<pre>
-SPF-Neutral:            CBV
-SPF-Softfail:           DSN
-SPF-PermError:          DSN
-SPF-TempError:          REJECT
-SPF-None:               REJECT
-SPF-Fail:               REJECT
-SPF-Pass:               OK
-</pre>
-
-<h2> Reputation </h2>
-
-If the sender has not been rejected by this point, and if a GOSSiP server is
-configured, we consult GOSSiP for the reputation score of the sender and
-SPF result.  The score is a number from -100 to 100 with a confidence
-percentage from 0 to 100.  A really bad reputation (less than -50 with
-confidence greater than 3) is rejected.  Note that the reputation is tracked
-independently for each SPF result and sender combination.  So aol.com:neutral
-might have a really bad reputation, while aol.com:pass would be ok.
-Furthermore, when a sender finally publishes an SPF policy and starts
-getting SPF pass, their reputation is effectively reset.
-
-<h2> Whitelists and Blacklists </h2>
-
-The administrator can whitelist or blacklist senders and sending domains by
-appending them to <code>${datadir}/auto_whitelist.log</code> or
-<code>${datadir}/blacklist.log</code> respectively.  In addition,
-recipients of internal senders (except for automatic replies like vacation
-messages and return receipts) are automatically whitelisted for 60 days, and
-senders that fail CBV or DSN checks are automatically blacklisted for 30 days.
-Whitelisted and blacklisted senders are used to automatically train the
-bayesian content filter before being delivered or rejected, respectively.
-<p>
-Real Soon Now users will be able to maintain their own whitelist and
-blacklist that applies only when they are the recipient.
-
-<h2> Content Filter </h2>
-
-Most messages have been rejected or delivered by now, but spammers
-are always finding new places to send their junk from.  For instance,
-we get around 10000 emails a day, of which around 500 are first time
-spam senders.  A bayesian filter is trained by the whitelists and
-blacklists, and scores the message.  What is likely spam is either
-rejected or quarantined.  If the sender is an effective SPF pass,
-then they get a DSN notifying them that their message has been
-quarantined.  (A DSN failure gets the sender auto blacklisted.)
-Else, if the reject_spam option is set, the message is rejected.  
-Otherwise, a CBV is done (failure gets the sender auto blacklisted)
-and the message is silently quarantined.
-<p>
-Normally, you don't want email messages to silently disappear into
-a black hole, so you should set the reject_spam option.  However,
-if you don't want your correspondent's email to get rejected, you can
-check your quarantine frequently instead.
-
-<h3> Honeypot </h3>
-
-You can also blacklist recipients by listing them as aliases of the
-'honeypot' dspam user.  These are collectively called
-the honeypot.  Any email to these recipients is used to train the
-spam filter as spam and chalk up a reputation demerit for the sender, then
-discarded.  It might be a good idea to blacklist the sender if it has SPF pass
-as well, but I'm afraid of accidents.
-
-<h3> Reputation </h3>
-
-Reputation is tracked by sending domain and effective SPF result.
-The GOSSiP server tracks the spam/ham status of the last 1024 messages
-for each domain:result combination.  When the server is queried during
-the SMTP envelope phase (MAIL FROM), it also queries any configured
-peers, and the scores are combined.  Domains with a history of spam for
-a given SPF result are rejected at MAIL FROM.  The GOSSiP system has
-a command line utility to reset (delete) a reputation for cases where a
-sender that was infected with malware is repaired.  In addition,
-the confidence score of a reputation decays with time, so a bad sender
-will eventually be able to try again without manual intervention.

-Title: Requirements
-
-<h2> Requirements </h2>
-
-<menu>
-<li> While the miltermodule will work with python 1.5, you probably
-want to use python 2.0 or better.  The python code uses a number of
-python 2 features.  The email support requires python 2.4.
-<li> Python must be configured with thread support.  This is because
-pymilter uses sendmail's libmilter which requires thread support.
-<li> You must compile sendmail with libmilter enabled.  In versions of
-sendmail prior to 8.12 libmilter is marked FFR (For Future Release) and
-is not installed by default.  
-Sendmail 8.12 still does not enable libmilter by default.  You must 
-explicitly select the "MILTER" option when compiling.  
-<li> When compiling Python milter against sendmail versions earlier than
-8.13, you must set MAX_ML_REPLY to 1 in setup.py.  There is no way to tell from
-the libmilter includes that smfi_setmlreply is not supported.
-<li> You probably want to use sendmail-8.13, since that supports multi-line
-SMTP error descriptions and SOCKETMAP.  You want SOCKETMAP for use with
-pysrs.
-<li> Python milter has been tested against sendmail-8.11 through sendmail-8.13.
-<li> Python milter must be compiled for the specific version of sendmail
-it will run with.  (Since the result is dynamically loaded, there could 
-conceivably be multiple versions available and selected at startup - but
-that will have to wait.)  This situation may only exist for sendmail
-versions prior to 8.12.  The protocol seems designed for backward 
-compatibility - and 8.12 is the first official milter release.
-<li> Mea Culpa!  After reading the Python Style guide, I realize that
-my Python code is not up to snuff.  Apparently mixed tabs and spaces
-are anathema to those using Windows editors, where tabs can be expanded using
-any arbitrary algorithm.  Other than that, my
-intuition matched Guido's pretty well - although I like to indent by 2
-rather than 4.  I will arrange to have tabs expanded to spaces when
-exporting new versions.  Until then, beware!
-</menu>
-
-<h3> <a name="aix4"> AIX 4.1.5 Requirements </a> </h3>
-To create sendmail RPMs for AIX, you can download my AIX 4.1.5 spec files 
-for <a href="/aix/sendmail.spec">sendmail-8.11.5</a> 
-or <a href="/aix/sendmail12.spec">sendmail-8.12.3</a>.  If you have
-not already set it up, I use a <a href="/aix/aix.spec">dummy RPM package</a>
-to represent the stuff that comes with AIX.  You might also want
-my <a href="/aix/python.spec">python-2.1.1</a> spec file for AIX.  It
-does not include Tk or curses modules, sorry.  If y'all trust me, you can
-download rpms for AIX 4.x from my <a href="/aix">AIX RPM directory</a>.
-<p>
-Sendmail-8.12 renames 
-libsmutil.a to libsm.a.  Unfortunately, libsm.a is an important AIX system
-shared library.  Therefore, I rename libsm.a back to libsmutil.a for
-AIX.  This presents a problem for setup.py.
-
-<h3> <a name="rh72"> RedHat 7.2 Requirements </a> </h3>
-
-If you are running Redhat 7.2, the distributed version of sendmail
-now enables libmilter by default.  RedHat 7.2 bundles
-the development libraries with the main sendmail package, so
-there is no sendmail-devel package.  However, they forgot to include the
-headers!  So you'll have to get the SRPM and modify it.  I suggest
-moving the static libs to a devel package and adding the headers.  If
-this is too much trouble, you can get the <a href="mfapi.h">mfapi.h</a>
-header for sendmail-8.6.11 from here and manually install it as
-<code>/usr/include/libmilter/mfapi.h</code>.
-<p>
-If you do modify the SRPM, I suggest renaming libsmutil.a
-to libsm.a - just like sendmail-8.12 will.  If you manually install
-mfapi.h or don't rename libsmutil.a, you'll
-need to force <code>libs = ["milter", "smutil"]</code> in setup.py.
-<p>
-If you have installed python2, and want
-python-milter to use python2, add <code>python=python2</code> to setup.cfg
-and build with <code>python2 setup.py bdist_rpm</code>.   
-
-<h3> <a name="rh62"> Redhat 6.2 Requirements </a> </h3>
-
-If you are running Redhat 6.2, the distributed version of sendmail
-does not enable libmilter.  You can download the Redhat 7.2 sendmail.spec
-modified to compile on RedHat 6.2:
-<a href="http://www.bmsi.com/linux/rh62/sendmail-rhmilter.spec">
-sendmail-rhmilter.spec</a>.  The <a
-href="ftp://updates.redhat.com/7.0/en/os/SRPMS/sendmail-8.11.6-1.7.0.src.rpm">
-SRPM for sendmail-8.11.6</a> is available from
-<a href="http://www.redhat.com">Redhat</a> under 
-<a href="http://www.redhat.com/support/errata/RHSA-2001-106.html">
-Errata for RH6.2</a>.  But that doesn't include the latest security
-patches since RH6.2 is no longer supported.
-<p>
-If y'all trust me, you can pick up source and binary sendmail RPMs for RH6.2
-from my <a href="http://www.bmsi.com/linux/rh62">linux downloads</a> directory.
-The lastest RPMs were built by taking a RH7.2 SRPMS and removing some
-RPM features from the spec file that RH6.2 doesn't support, then
-recompiling on RH6.2.  You can check this by installing the RH7.2 SRPM,
-then diffing my sendmail.spec with theirs.  Then run
-"rpm -bb sendmail-rhmilter.spec" when you are satisfied.
-<p>
-If you have installed python2, and want
-python-milter to use python2, add <code>python=python2</code> to setup.cfg
-and build with <code>python2 setup.py bdist_rpm</code>.
-You'll need to install the sendmail-devel package to compile milter.

-
-Someone at IP address %(connectip)s sent an email claiming
-to be from %(sender)s.  
-
-If that wasn't you, then your domain, %(sender_domain)s,
-was forged - i.e. used without your knowlege or authorization by
-someone attempting to steal your mail identity.  This is a very
-serious problem, and you need to provide authentication for your
-SMTP (email) servers to prevent criminals from forging your
-domain.  The simplest step is usually to publish an SPF record
-with your Sender Policy.  
-
-For more information, see: http://openspf.org
-
-I hate to annoy you with a DSN (Delivery Status
-Notification) from a possibly forged email, but since you
-have not published a sender policy, there is no other way
-of bringing this to your attention.
-
-If it *was* you that sent the email, then your email domain
-or configuration is in error.  If you don't know anything
-about mail servers, then pass this on to your SMTP (mail)
-server administrator.  We have accepted the email anyway, in
-case it is important, but we couldn't find anything about
-the mail submitter at %(connectip)s to distinguish it from a
-zombie (compromised/infected computer - usually a Windows
-PC).  There was no PTR record for its IP address (PTR names
-that contain the IP address don't count).  RFC2821 requires
-that your hello name be a FQN (Fully Qualified domain Name,
-i.e. at least one dot) that resolves to the IP address of
-the mail sender.  In addition, just like for PTR, we don't
-accept a helo name that contains the IP, since this doesn't
-help to identify you.  The hello name you used,
-%(heloname)s, was invalid.
-
-Furthermore, there was no SPF record for the sending domain
-%(sender_domain)s.  We even tried to find its IP in any A or
-MX records for your domain, but that failed also.  We really
-should reject mail from anonymous mail clients, but in case
-it is important, we are accepting it anyway.
-
-We are sending you this message to alert you to the fact that
-
-Either - Someone is forging your domain.
-Or - You have problems with your email configuration.
-Or - Possibly both.
-
-If you need further assistance, please do not hesitate to
-contact me again.
