I think I understand what Franco is asking. He wants to stop an external
sender (spammer) from setting their From: address to appear like its coming
from his domain space and then having his MTA accept this e-mail for local
delivery.


Correct?

BTW: By default, sendmail should NOT be relaying (as in open relay) to
anyone outside your domain space when someone sets their "From:" address to
be the same as your domain space. It should accept the e-mail for local
delivery only, unless overridden. Unfortunately, I don't remember how to
implement what your asking using sendmail. It's a piece of cake in postfix
though. Sorry!
