Hello,
Is there a way for me to block mail that claims its from a certain domain,
based on my own valid ip address list?
Example:
myserver.com - IP address 1.2.3.4
If a messages comes in from any server other than 1.2.3.4 for domain
myserver.com reject it?
I know SPF/DKIM/DMARC would also help here, but trying to almost make my
own ACL.
Thanks
