POSTFIX and blocking domain name (e.g fundscave.com or "encirc" from encirc.iloantoday.com)

Hi everyone,

I'm getting spammed again and just wondering how to block spam from a domain name. I thought I could do it through main.cf via rejected_domains but that's for TLD. Any ideas on blocking domain names?

e.g. fundscave.com
& this culprit...

encirc" from encirc.iloantoday.com

cheers,
Andrew

Numerous ways to accomplish this; a search for "how to block domains in postfix" yields a lot. Some good suggestions:

..along with using the sender_access file, but the blacklists are probably the best way to go, if you want to block spammers wholesale. If it's only two domains, then sender_access might be better.
