In a prior post, you indicate that IncomingRunner was detecting a
RejectMessage exception. You wrote:
>(Your modified) code in IncomingRunner.py currently looks like this:
> except Errors.RejectMessage, e:
> mlist.BounceMessage(msg, msgdata, e)

> msg.get('message-id', 'n/a'))
> return 0
and presumably you were seeing that log message. Thus, we know it is a
'reject' and not a 'discard'.
It looks like there are only 3 paths through Moderate.py that result in
a reject. These are:
Post is from a moderated member and the list's member_moderation_action
Post is from a non-member in reject_these_nonmembers and not in accept
or hold _these_nonmembers.
Post is from a non-member not in *_these_nonmembers and
generic_nonmember_action is reject.
There are different values for the error message, e, that can
distinguish the first case from the second two, but if this isn't
enough, I would add some information to the logging statement above.
syslog('vette', 'Message bounced, listname: %s, \
msgid: %s Subject: %s, Sender: %s, Error: %s',
msg.get('subject', 'no subject'),
Also, in all these cases mlist.BounceMessage(msg, msgdata, e) should be
attempting to send a reject message to the poster. There should at
least be something in the smtp* logs about this.
