So it takes Mailman over a minute to deliver to Postfix for 10
recipients. No matter what Mailman is doing, this is way too long by
over a factor of 100.
Various things could be at the root of this, e.g.
reject_unknown_recipient_domain in smtpd_recipient_restrictions
particularly in combination with slow DNS lookups.
To say more, we'd need to see the output from 'postconf -n' and the
contents of mm_cfg.py, but this is really a Postfix tuning issue, soo
see <http://www.postfix.org/TUNING_README.html> and other Postfix
resources as well. There is also information in our wiki, but a lot of
the Mailman specific stuff is out of date, but go to
<http://wiki.list.org/FrontPage> and search titles for "performance".
