Somebody here noticed the following "feature" of mail (4.2 BSD).  Under
certain conditions, a user "xyzu" can do a "set user=abcd" and send mail
to user "pqrs".  To "pqrs" it appears that "abcd" sent the mail (xyzu <>
abcd).  This could cause misunderstandings or such if "xyzu" were malicious.
Is this a feature or a bug?  Thanks.
