[Mailman-Developers] problem with VERP stuffing all the messages in one connection
I was hoping to have a crack at a patch today, but I've been too busy
converting my whole exim configs to exim 4.
When VERP is enabled, mailman apparently sends all the Emails over one SMTP
When exim receives more than smtp_accept_queue_per_connection messages in
one connection, it spools everything without trying to resend it. That's
actually very bad, because list messages then get delayed by 30mn or more
(waiting on a queue runner to pick them up, one per one, and you can imagine
that it's a lot of queue entries to clean up (# of subscribers x # of
messages sent in the last 30mn)
I've currently set that to 1000 on one of my test servers, but that's not
Mailman needs a MAX_RCPT_PER_SMTP setting and close the SMTP connection
after sending that many messages, and open up a new one.
Or did I miss something obvious?
