    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.

    user1@domain.com can email user2@domain.com providing he is useing our outgoing server (local delivery)
    user3@domain.com isnt useing our outgoing server and when the email arrived into the filters its marked as spam.

    In your cPanel > Mail section > Default Address, what do you hate this set to here?

    All domains on this menu should be set to:
    Discard with error to sender (at SMTP time)
    With some sort of message like:
    No Such User Here
