[Mailman-Users] Mailman stopped delivering mail

This is very interesting.  I took your suggestion and deleted the SMTPHOST 
statement from the mm_cfg.py and Mailman immediately started working.  I 
don't know why this would make a difference.  I know that we had this same 
SMTPHOST statement in the mm_cfg.py file for quite a long time, years even, 
and we never had a problem with it until recently.

Thanks very much for the helpful tip.
