This can happen for many reasons. 
Quitting employees, dropping domains, death whatever. 

They should be *somehow* auto removed after a certain number of bounces.

BUMP

This has been going on for more than a week now.  I'm quite confident
that there have been hundreds of auto-replies.  (I'm seeing 285 incoming
message from the NANOG mailing list since I became aware of the auto-reply.)

I'm really surprised that there has not been any reply or action by the
NANOG list owner(s).  I would have hoped, if not expected, better, or
any, response by now.
