OK, here's what I found:

Mar 12 10:08:11 2010 (31200) delivery to xelloss at slayers.org failed
with code 45 0: 4.1.2 <xxx at slayers.org>: Recipient address
rejected: Domain not found

I've found similar messages with xxx at fanfic.net at the end.  Certainly
mailman should be running these as bounces?

Moreover, I should note that many of the users are not getting
messages, and in logs/smtp, I see messages such as this:

Mar 12 13:32:35 2010 (31200)
<905831dc1003100904u3451a9b7kbc405d64f96d9b39 at mail.gmail.com> smtp to
ffml for 2 recips, completed in 60.504 seconds

(Note that this is normally right around 1,000 recips.)

Semi-related message from logs/post:

Mar 12 13:35:37 2010 (31200) post to ffml from
dennisthetiger at chez-vrolet.net, size=1444,
message-id=<Pine.LNX.4.64.1003121020550.31541 at kimba.chez-vrolet.net>, 2
failures

In short, what's up, and how to fix this?
