You need to modify your mailer to check the sender of outgoing
mails (and the receiver of incoming mails) to match a user list.
Unfortunately, I find no standard mailer feature that can do this
so I hacked sendmail's checkcompat function (as described in O'Reilly's
Sendmail reference book) to do the actual checking.
There is some information that Sendmail 8.10 will incorporate a
"perl-like" scripting language that would allow the mailer to do such
manipulations. Until then you have will have to code in C to do
the actual checking.
