I agree that the local-part of the address is rarely interesting, but the
suggestions so far still may not fit enough of the domain part into the
subject (especially for those of us only seeing 31 characters.  How about
 
  Subject: LSTOWN-L: error from ALBERT.PHYSICS.ARIZONA.EDU
    or     LSTOWN-L: bounce from ALBERT.PHYSICS.ARIZONA.EDU

Also, can we have something similar for bounces of messages from LISTSERV
itself unrelated to any list (bounced to postmasters)?  Perhaps the same
format with "LISTSERV:" instead of "listname:" (since you can't have a
list woth the same name as the server).
