The stats I attached show that m.p.o is sending out a gigabyte of email per
day, and Mailman is the only significant source of outgoing email on m.p.o
(I expect that the traffic from the comp.lang.python mailing-list gateway
alone dwarfs all of Zope's list traffic combined).  There's no backlog, and
the box isn't thrashing (although you can't tell that from the stats alone).

I'd try again, if I were you.  Since the m.p.o postmasters are no longer
fighting any problems with m.p.o's email, (a) they may be able to explain
what they did now that it's *done*; and, (b) they have more "spare time"
now.  OTOH, if the problems were due to flakiness in a particular Zope
mailing list, perhaps they got such improvement simply by getting that list
off the m.p.o hardware.

I run, e.g., zodb-dev at zope.org.  What specifically could I do to help
determine if that list is causing you problems?
