You can implement RBLs to fight spam too. Also like Stephen mentioned, if you don't already have SPF, DKIM and DMARC setup, this video may help you set them up:

Hello all:
I run my own DNS and email servers.
I have the SPF records properly set but I am having a crippling amount of

Thanks

A mouse trap, placed on top of your alarm clock, will prevent you from rolling over and going back to sleep after you hit the snooze button.
