[Mailman-Users] Lists stop working

[Niklas Nikitin]

Hi,

I have some problems with my Mailman server. I am running Mailman 2.1.2 
(installed from source) on a RedHat 8.0 Linux server (using Sendmail 
version 8.12.8-5.80). The problem is the following:

I send an eMail to one of the lists, I can see in my /var/log/maillog;

     Jun 10 11:27:03 osiris sendmail[2756]: h5A9R392002756:
     from=<Niklas.Nikitin at xxx>, size=502, class=0, nrcpts=1,
     msgid=<5.2.1.1.2.20030610112857.00b9b740 at xxx>, proto=ESMTP, daemon=MTA,
     relay=cassini.xxx [193.10.220.37]

     Jun 10 11:27:03 osiris sendmail[2757]: h5A9R392002756:
     to="|/usr/local/mailman/mail/mailman post nicke-test",
     ctladdr=<nicke-test at xxx> (8/0), delay=00:00:00, xdelay=00:00:00,
     mailer=prog, pri=30704, dsn=2.0.0, stat=Sent

that the server is receiving the eMail and is forwarding it to Mailman. But 
in Mailmans logs I will not find any information that it has received the 
eMail and no eMail is sent to the members on the list. If I dump all 
members of the list to a file, remove the list, create the list again and 
add all members, the list is working again for a while, and then it repeats 
again.

It is not all lists that behave like above, other lists are working just fine!
