Somewhere on the net mailings from SAS-L (a peered list) have been re-fed into
the list with "Undetermined origin ...".
I thought I can prevent the distribution of this junk by SERVE-ing the From: (
<POSTMASTER@node> )  OFF, but  it obviously doesn't  work. Never  thought much
about SERVE OFF but does it work only  at the primary LISTSERV (and not on the
peers) or is this a bug (on 1.6e) ?
