Blocking From Users

[Brent Kennedy <br...@cfl.rr.com>]

Just a quick question.  If I add an entry into the configuration file to
block all emails sent from "*@mycompaniesdomain.com", that should block
anyone trying to send emails into my mail server using my companies domain
as a spoof.  The question is.. Will this end up quarantining all emails sent
to mycompaniesdomain.com?

I am only using SA to filter incoming emails.

Thanks
