How to block spam email

Post by LanceAllen »

Hello, I've been receiving numerous spam emails for recipient addresses that we no longer use. I attempted to block them using the Blacklist and spam.blacklist.rules, but it didn't work. Do you know any way to block these email?

Is this still an issue for you?

There is a way to configure postfix to know which email addresses are valid and immediately drop those messages to invalid email addresses. That may be a workable solution for you.

It's called the postfix address verification.
