Postfix sends the list message it to the remote server, which shows that
it was accepted by the Mailman server. The Mailman server has logs that
show that the message was directed to the command 'post' to list 'test7'.
However, nothing happens after that for 2-7 hours. Once it actually sends
to the list, there are smpt.log entries that show it going to 'x recipients'
The problem is not non-delivery but extremely slow delivery, anywhere from
2-8 hrs,even for a small list (2 subscribers) like the test7 list. The
Mailman server has over 600 lists and 250,000 subscribers. Some of the
lists have 40,000 subscribers. Additionally, there is quite a bit of spam
being sent to the list owner addresses and other attempts at posts by
spammers, many which are flagged and blocked. That is just to point out
that there is a lot going on with the Mailman server.
What would be some reasons for such long delays and why does it seem that
they seem to be "released" all at the same time. If they have been handed
off to Mailman,where are they held during this long delay? Are there some
optimizations that could be made in mm_cfg.py and/or with Postfix? I saw
some reference to some work that had already been done with this, but it
appears to be from 2008.
Thank for any suggestions that you might have.
