Question How to reject mail from nonexistent domains in postfix

J

Hello

I'm receiving emails from nonexistent domains, for example: [email protected] that's clearly a nonexistent domain, and the mail log says:
spf=none (sender IP is 45.8.126.20)
If i check on mxtoolbox.com i see there's no SPF record published, that's not even a valid domain.
Regards
