[Mailman-Users] detecting administrivia requests in "bounces"

[James Dinkel]

For some reason, my users like to send emails to 
listname-bounces at listserver.com.  I guess maybe because that is what is 
in the From: address on emails they recieve.  Anyway, they will be 
emails with a single request in them like "help" or "subscribe" but they 
dome to me because the bounce filter couldn't filter them out.  Is there 
anyway to have these checked for Administrivia?
