We are not communicating here. The above makes no sense to me. I think
the sequence is:

 - List mail arrives at the local Postfix.
 - Postfix delivers to the local Mailman.
 - Mailman delivers - here I don't know if to the local Postfix for
relay to the remote server or directly to the remote server. The
mm_cfg.py setting for SMTPHOST determines this. The Default is localhost
meaning relay via the local Postfix.

OK, so here you are saying that the delay is definitely in Mailman. I.e.
Postfix delivers to the mailman mail wrapper which presumably
immediately queues the message in Mailman's in/ queue, and it's a long
time later that Mailman logs the delivery.

What is the processing time in the smtp log entry. Is it a few seconds
or less or hours?

I'm guessing that during this time IncomingRunner or OutgoingRunner or
both are asleep. Do you have a setting in mm_cfg.py for
QRUNNER_SLEEP_TIME? The default in Defaults.py is (or should be)


If you have set this to a few hours, it would explain the behavior you
are seeing. If not, when does the post get archived? Is that delayed too?

Also, messages in the in/ queue are processed by IncomingRunner and then
queued in the archive/ queue for ArchRunner and the out/ queue for
OutgoingRunner. You could look and see if messages move from the in/
queue quickly or not.

Note that if you have set QRUNNER_SLEEP_TIME to say 4 hours, messages
can sit in the in/ queue for an average of 2 and up to 4 hours before
moving to the out/ queue where they may wait up to an additional 4 hours
before being sent.
