Hi all --

I'm trying to figure out why a particularly unreliable address has not
been disabled by Mailman yet.  As near as I can tell (mostly by looking
at Exim's retry database), the mail server for this user's domain has
not been working since late October: either it answers and fails with
"452 4.4.5 Insufficient disk space; try again later", or it simply
refuses the SMTP connection request.  In either case, mail to this user
sits in our local Exim queue for four days until our Exim times it out
and sends the bounce message to Mailman.

Mailman has certainly been getting these bounce messages; here's an
excerpt from ~mailman/logs/bounce:

Nov 07 18:17:02 2001 (24867) mems-talk: [EMAIL PROTECTED] - first
Nov 08 02:24:01 2001 (27027) mems-talk: [EMAIL PROTECTED] - 3 more allowed over 402780 
secs
Dec 09 10:55:01 2001 (29717) mems-talk: [EMAIL PROTECTED] - first
Dec 09 10:55:01 2001 (29717) mems-talk: [EMAIL PROTECTED] - 2 more allowed over 345599 
secs

The weird thing is that around 11am on Dec 9, there were a *lot* of
these bounces -- presumably all the list traffic for the last four
days.  Mailman logged them all:

bounce:Dec 09 10:55:02 2001 (29717) mems-talk: [EMAIL PROTECTED] - 2 more allowed over 
345599 secs
bounce:Dec 09 10:55:02 2001 (29717) mems-talk: [EMAIL PROTECTED] - 2 more allowed over 
345599 secs
bounce:Dec 09 10:55:02 2001 (29717) mems-talk: [EMAIL PROTECTED] - 2 more allowed over 
345599 secs
bounce:Dec 09 10:55:02 2001 (29717) mems-talk: [EMAIL PROTECTED] - 2 more allowed over 
345599 secs
[...dozens more skipped...]

However, it never disabled the subscription.

In fact, Mailman hasn't disabled *anything* since Nov 20, despite plenty
of bounces.  Hmmm.

Ideas?  Clues?  Advice?
