        I too run a list based at brownvm, and have seen the same thing.  It
        seems to occur when the listserv can't find A records (see typical
        listing below), but does its thing *the first time it happens*.  Seems
        just a bit harsh...
 
        Note also that I've been seeing a lot of list messages originating from
        [log in to unmask] instead of directly from
        brownvm.brown.edu.  The sample below is one of them.  Does this relate
        to the auto-deletion?

**********************  typical auto-delete message  *************************
 
The following users have been removed ("auto-deleted", in list owner jargon)
from the STATLG-L list as a  result of the nondelivery error report enclosed
below.  No action  is  required from  you;  this message  is  only for  your
information.

 address of deleted subscriber
 
This delivery error is in a special format that allows software like
LISTSERV to automatically take action on incorrect addresses; you can
safely ignore the numeric codes.
 
Note: delivery error converted to LMail format at BROWNVM.BROWN.EDU.
