Setting up a gate-keeper

I had a thought the other day concerning our apparent problem with
undesireable mail.  Would it be possible to program a gate-keeper that
would check that the "From" address was valid and reject any mail that
has a non-valid return address or perhaps some other such iteration of
this comcept.  It appears that one of the commonalities of these spam
posters is that they can not be contacted back.
