Access to LISTSERV for the address mentioned in the message has been
terminated in one of two ways:
 
(1)  Automatically by LISTSERV because it has received 20 invalid commands
in a row from the address in question.  Access can be restored by anyone
other than the affected user sending a "SERVE address" command to LISTSERV.
 
(2)  Manually by a LISTSERV postmaster sending a "SERVE address OFF" command
to LISTSERV.  Access is restored when a LISTSERV postmaster sends a
"SERVE address" command.
