[Mailman-Users] Mail not sending mail problem

[Mike Alberghini]

As it turned out, one of the other sysadmins created a list to collect
the bounced mail from our mail servers.  Every bounce going to gsu.edu
was being sent to one mailman list.  In about 12 hours that was over 11000
messages.  

The problem was that the mailman ArchRunner was struggling to keep up.
It was hogging the CPU on the box and keeping anything else from happening.
Mailman was under Denail of Service attack from our own webserver. :)

I just thought I'd let the list know this happened, because someone could
use this to screw up a mailman server rather easily.
