We have recently been getting reports of spam emails from our own domain name addresses.

My question is is there a setting in the spam filters we can apply that will block all emails from @domain.com that didn't originate locally? (users should only be able to send @domain emails from this one server)

ie.

[email protected] can email [email protected] providing he is useing our outgoing server (local delivery)
[email protected] isnt useing our outgoing server and when the email arrived into the filters its marked as spam.
