Someone's re-invented the wheel and created another address to add to
 your "SERVE OFF" list...  The original message was lost in the mail
 loop between <listserv@jhuvm> and <[log in to unmask]>, so
 I don't know much about how this developed.  Since the mail was sent
 LISTSERV and not a mailing list, the loop stopped after 10 times.  I'm
 not sure if this "mailer-agent" will bounce mail to a mailing list
 address or not, but it's quite possible.  I'd suggest serving it off,
 to avoid the possibility of ending up with a loop that won't self-
 terminate!

 PS - I've CC'd the postmaster of the system in question, but since mail
 to "root" is failing here, he/she may very well not get the message.
 So, don't assume it will be changed anytime soon, they may not even know
 there's a problem.
