Hello @z3d3m0n,

The following thread offers some user-submitted examples that you may find helpful:

Block incoming emails from domain

You'd simply need to adjust the filter rule to block email from a domain name that's NOT from a list of domain names.

Thank you.

If you want to do this at server level, then you may have to look at something like CSF mailscanner.
Also, there is an exim mod to block domains, but i found it tempremental.
Search for exim_blacklist, it will appear somewhere.

Alterntively, if you want to do this at domain level then a global email filter in your cpanel will do this.
Although compiling the rule could be tedious.
