Hi all, I need to reject envelope message with the following parameters: X-Original-To: [email protected] Delivered-To: [email protected] From: [email protected] These were specific names not general names, So i made the following in header_checks file /etc/postfix/header_checks: /^X-Original-To: (donotreply@support\.domain-af\.com) +/ reject forged client name in X-Original-to: header: $1 /^Delivered-To: (donotreply@support\.domain-af\.com) +/ reject forged client name in Delivered-to: header: $1 /^From: (root@domain\.net) +/ reject forged client name in From: header: $1 /^Message-ID:.*@(cgremtpprd\.realdomain\.net)/ reject forged domain name in Message-ID: header: $1 Is that Ok ? should we add if condition to group them all ? I need your help please, Thanks in advance
