[Mailman-Users] Mailman 2.1.8 posting problems

[Hennie Rautenbach]

Hi there,

I run Mailman 2.1.8 on a Debian (Sarge) box. The MTA is Postfix (With 
amavisd, spamassasin and clamav). I have two fairly busy lists that each 
have less than 1000 subscribers. Yesterday something broke. No-one 
touched the server (irrelevant I suppose). Postings are submitted but 
don't get distributed to the subscribers. I have checked all logs and 
made sure the MTA and qrunner is running. I can send and receive mail to 
and from  the server from my account. It is just the mailman stuff that 
don't come through anymore. There are quite a backlog of .pck files in 
~/qfiles/out and ~/qfiles/retry. The only notable error is in the 
~/logs/post file. Where previously I had "success" status with each 
posting I now get "failures" as per the log example below:

Any idea what may have caused my messages to appear with the "failures" 
status ? Any help in diagnosing the problem will be greatly appreciated. 
I have fiddled with it quite a bit but am at a dead end...

Kind regards,

Hennie
