[Mailman-Users] A single list not working

[Erin]

Hi all.. I'm new to the list and have a quick question.

I have been running mailman for nearly 2 years now, and ran into an odd
problem this week that I *have* to be missing the obvious on.

I have about 10 lists..one of which has about 22K users. Last week,
posting to this list worked just fine. This week it doesn't appear to do
anything with the message.

All other lists are working fine.

The qmail log shows 

1025279881.775349 new msg 112244
1025279881.775473 info msg 112244: bytes 1478 from
<brad.lastname at domain.net> qp 9193 uid 100
1025279881.780019 starting delivery 75443: msg 112244 to local
outages at lists.domain.com
1025279881.780032 status: local 1/10 remote 0/20
1025279881.787793 delivery 75443: success: did_1+0+0/
1025279881.787801 status: local 0/10 remote 0/20
1025279881.787807 end msg 112244

The .qmail file for includes the correct !preline message in it, all
other lists are working fine, so I have ruled qmail itself out.  There
were no major configuration changes to this list.

Can anyone tell me what i'm over looking? I would hate to have to
rebuild this list.

Thank you

Erin Martin
