Hello, I am just switching to postfix for my mailserver. I wonder, if and how the following is possible:
I have a catchall for a certain domain (lets call it catch-all.com). But certain addresses (like [email protected]) just get to much spam. So I want to block them! But I do not want to bounce them, it causes to much traffic. I want to block them on the smtp level. If someone sends an mail to [email protected], he should get an "user not found" response. Thanks! Nathan
