[Mailman-Users] Mailman error

[Clovis Tristao]

Hi,

Since yesterday the mailman stopped sending messages to the lists.

The message:

/var/log/mailman/post:
Oct 06 10:27:50 2009 (2335) post to listname-l from username at foo.com, 
size=2633, message-id=<4ACA34FA.8030407 at foo.com>, 322 failures

/var/log/mailman/smtp-failure:
Oct 06 10:35:50 2009 (2335) delivery to username at foo.com failed with 
code -1: Server not connected

How do I track and / or resolve the problem?

We removed the accounts of users of the machines and they were not 
removed from the listname-l list.
How do I fix this problem?
I thank you,

Clóvis
