[Mailman-Users] mailman stopped delivering mails, how to debug?

[Olaf Foellinger]

Hi,

mailman stopped to deliver mails to my mailing lists. All I see in the
mail.log is

Jul  9 08:07:11 camelot postfix/smtpd[24216]: connect from domain.tld[IP]
Jul  9 08:07:11 camelot postfix/smtpd[24216]: setting up TLS connection from domain.tld[IP]

The mailman log does not show any entries. It's a virtual server, the
provider has recently updated the kernel to 

# uname -a
Linux camelot 2.6.18-028stab060.8 #1 SMP Mon Feb 9 20:21:36 MSK 2009 i686 GNU/Linux

The message has been added to the archives but has not been delivered to
the recipients.

How can I debug the problem?
