Better include asbestos underwear too. You put your glutius
maximus in danger when you tell some people to mod their systems ;-)
But seriously, can't LISTSERV just insert the RSCS origin into the
From: field in such cases? It already adds the "Warning -- RSCS tag
indicates an origin of <user>@<node>", so it knows roughly where the
file came from. With the warning, all the necessary caveats are in
place, and the user ought to be suspicious of addresses that aren't
what they seem to be.
