This is an automatically generated Delivery Status Notification.

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://spfhelp.net
|
||||
|
||||
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.

Here is a history of user visible changes to Python milter.
|

0.8.7 Move spf module to pyspf
|
||||
Prevent PTR cache poisoning
|
||||
More lame bounce heuristics
|
||||
Do plain CBV when template is missing
|
||||
0.8.6 Support CBV timeout
|
||||
Support fail template, headers in templates
|
||||
Create GOSSiP record only when connection will procede to DATA.
|
||||
More SPF lax heuristics
|
||||
Don't require SPF pass for white/black listing mail from trusted relay.
|
||||
Support localpart wildcard for white and black lists.
|
||||
Delay reject of unsigned RCPT for postmaster and abuse only
|
||||
Fix dsn reporting of hard permerror
|
||||
Resolve FIXME for wrap_close in miltermodule.c
|
||||
Add Message-ID to DSNs
|
||||
Use signed Message-ID in delayed reject to blacklist senders
|
||||
Auto-train via blacklist and auto-whitelist
|
||||
Don't check userlist for signed MFROM
|
||||
Accept but skip DSPAM training for whitelisted senders without SPF PASS
|
||||
Report GC stats
|
||||
Support CIDR matching for IP lists
|
||||
Support pysrs sign feature
|

Support localpart specific SPF policy in access file
|

|

0.8.5 Simple trusted_forwarder implementation.
|

Fix access_file neutral policy
|

Move Received-SPF header to beginning of headers

|
||||
When bms.py can't find templates, it passes None to dsn.create_msg(),
|
||||
which uses local variable as backup, which no longer exist.
|
||||
|
||||
Purge old GOSSiP records nightly.
|
||||
|
||||
Find and use X-GOSSiP: header for SPAM: and FP: submissions. Would need to
|
||||
keep tags longer.
|
||||
|
||||
Generate DSNs according to RFC 3464
|
||||
|
||||
Parse incoming 3464 DSNs for "Action: failed" to recognize delayed
|
||||
failures. This works regardless of Subject.
|
||||
|
||||
Get temperror policy from access file.
|
||||
|
||||
When training with spam, REJECT after data so that mistakenly blacklisted
|
||||
senders at least get an error.
|
||||
|
||||
Reporting explanation for failure should show source if sender
|
||||
provided explanation.
|
||||
|
||||
Reports PROBATION even when rejecting message (works, but confusing in log).
|
||||
|
||||
Bug in Auto-whitelist. Recent Auto-whitelist doesn't override expired entry.
|
||||
|
||||
DONE Delayed_failure detection needs to handle multi-line header fields.
|
||||
Also, delayed_failure should be recognized when addressed to
|
||||
postmaster@helodomain
|
||||
|
||||
Need to use wildcards in blacklist.log: *.madcowsrecord.net
|
||||
Need to exclude emails like !*-admin@example.com in whitelist_sender.
|
||||
|
||||
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.
|
||||
|
||||
Add auto-blacklisted senders to blacklist.log with timestamp.
|
||||
|
||||
Received-SPF header field should show identity that was checked.
|
||||
|
||||
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 sender 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.
|
||||
|
||||
FIXME: DSN for Permerror shows 'None' for error under some condition.
|
||||
|
||||
Another metaDSN format:
|
||||
Subject: Delivery Report
|
||||
...
|
||||
Original-Envelope-ID: SRS0...@...
|
||||
|
||||
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.
|
||||
|
||||
Allow blacklisted emails as well as domains in blacklist.log. Use same
|
||||
data structure as autowhitelist.log. 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).
|
||||
|
||||
Added Message-ID header to DSN with SRS signed sender. When seen on incoming
|
||||
rfc ignorant failure message, blacklist sender.
|
||||
|
||||
Allow verified hostnames for trusted_relay. E.g. HELO name that
|
||||
passes SPF.
|
||||
|
||||
Table of sendmail macros for documentation.
|
||||
|
||||
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.
|
||||
|
||||
Require signed MFROM for all incoming bounces when signing all outgoing mail -
|
||||
except from trusted relays.
