[Mailman-Users] Mailman and Postfix queue (mailq) question

[Christopher Adams]

This may be a question for the Postfix-Users list, but I know some of 
you are using Postfix as your MTA.

My questions is about some of the entries in the queue, when I run 
mailq. What is the part: 
libs-or-bounces+c620c0ce6987c4a2e5753ed1de6684d079cce346 at mailmanhost.com

Many of the bounces just list libs-or-bounces at mailmanhost.com
