Apparently, Michael had his options set to receive copies of his own
postings to britarch also had his auto-reply set to respond to incoming
When he in appropriately sent an unsubscribe message to britarch instead of
sending it to LISTSERV he received a copy of it and auto-replied to it and
received a copy of that etc etc.
It is reminiscent of the old days on britarch and other discussion lists
where that would occur with some frequency - until steps were judiciously
taken to prevent it. Considering the number of auto-replies we still
receive it is fortunate that those preventive measures were taken.
