Hi, I've created the rules to block forged Reply-to and Return-Path using my domains. I've followed the examples in http://www.postfix.org/BACKSCATTER_README.html.
This is my rule:
/^(From|Return-Path|Reply-To):.*\b(domain\.com\.br)\b/
discard forged sender address in $1: header: $2
We need to create some exceptions. Would placing the following rule in the
same file work?
/^(Return-Path|Reply-To):.*\b(user1@domain\.com\.br)\b/
dunno
Kind regards.
Fabio
