[Mailman-Users] Why some messages aren't distributed?

[Jon Carnes]

What are your "Delivery defaults" set to in ~mailman/Mailman/mm_cfg.py
(or Defaults.py)?

===========
#DELIVERY_MODULE = 'Sendmail'
DELIVERY_MODULE = 'SMTPDirect'

# MTA -- but then also see POSTFIX_STYLE_VIRTUAL_DOMAINS.
MTA = 'Manual'

POSTFIX_STYLE_VIRTUAL_DOMAINS = []

POSTFIX_ALIAS_CMD = '/usr/sbin/postalias'
POSTFIX_MAP_CMD = '/usr/sbin/postmap'

SMTP_MAX_RCPTS = 500

SMTP_MAX_SESSIONS_PER_CONNECTION = 0

MAX_DELIVERY_THREADS = 0

SMTPHOST = 'localhost'
SMTPPORT = 0                                      # default from smtplib

==================

Have you tried running with
  DELIVERY_MODULE = 'Sendmail'

There are some archive messages from Barry that explain it. 

I believe they are for messages that take too long for Mailman to
process.  There might be a problem with their headers or with the
system. In any case, rather than let the message clog up the queue,
Mailman gives up on the message and shunts it.

Check out the ~mailman/bin/unshunt command

Something similar can happen.

One of the features of version 2.1 is that it times it's processes as a
last resort to figure out if a process is hung somehow.  As an example,
the Archiver qrunner has a specified number of minutes to handle each
message, if it exceeds that time limit then it is killed and restarted
after all the other qrunners have been given another go.

(at least that is how I read the code...)

BTW: are you running any Spam/virus scanning in conjunction with your
Sendmail?
