Our mx gateway is bombarded with spoofed emails supposedly from us (the emails claim to be random_name@ourdomainname.com) sent from random sources. I have our mx gateway configured to reject and defer all of this email and only accept email @ our domain name from our sending server so the emails are not being relayed but they are however generating an insane amount of activity in the logs and our mail queue often has sometimes 8k or more of these deferred emails in the queue.

What is the proper way to reject all spoofed email that is supposedly from our domain without ending up in the queue or generating some much noise in the logs? Is there a way to do that?

Thanks,
Luke

Re: Dealing with spoofed email clogging up the mail queue.

This should be rejected by iRedAPD plugin "reject_sender_login_mismatch". If you're running an old iRedAPD, please upgrade it first.
