[Mailman-Users] Problems after postfix upgrade

[Hennie Rautenbach]

Hi there,

I run Mailman 2.1.6 compiled from source on a Debian box running Postfix 
as its MTA.  It's been working for a long time now untill I decided to 
do a general upgrade lastnight (apt-get update). Then Mailman promptly 
stopped working. Very little in terms of errors. The posts to mailman 
simply dissapear. I see there are numerous references on the Web about 
the "group mismatch" error. I suspect my problems may be related to it. 
However, I don't get any boucned mail to track and errors.  I need 
someone with a bit of patience to assist  me to track and rectify the 
problem.

Below is a sample from the /var/log/mail.log file:

Nov 23 16:07:01 nova postfix/pickup[5019]: 769427B3: uid=65534 
from=<hennie at sab3net.co.za>

post safari)
Nov 23 16:07:02 nova postfix/qmgr[3658]: 769427B3: removed

Who can point me in the right direction here ?

Regards,

Hennie
