-Check ESMTP NOTIFY before sending real DSNs.  Just use CBV if DSNs are
-not wanted.
+Support smfi_negotiate and auto negotiate only those callbacks for which 
+Milter.Milter methods have been overridden.  (Python should be able to
+do that.)
 
-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.

+<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.

-
-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.
