This should  be "Filter=  Also,postmast*@*,etc". How  did you  enter that
keyword into the list? In principle it should have been rejected.

This is  an incompetently forged  message resulting in an  invalid RFC822
header.  LISTSERV  can't  determine  the  true origin,  and  sets  it  to
[log in to unmask] In that  case it also skips the  filter check since
it knows  the message is not  really from POSTMASTER. The  reason it uses
POSTMASTER is  to have a  valid address one can  reply to, rather  than a
black hole. Actually I should  probably change this to owner-LISTSERV and
remove the filter skip.
