Hi guys. I have some postfix servers running as a relay/gateway for internal mails, when they want to go to the world wide web.
These internal servers i trust, but sometimes mails from CRON gets send to me, i know, the best solution would be to disable cron mails but that is more for the long term solution. So, for now i want to simply discard mails going through. My header_checks: /To: [^@]*@.*\.internal\.domain\.com/ DISCARD And this seems to work fine if i run the postmap -q command: postmap -q "To: t...@horse.internal.domain.com" pcre:header_checks DISCARD But, sometimes i get this kind of email: original_recipient: postmas...@horse.internal.domain.com recipient: postmas...@horse.internal.domain.com From: "User" <r...@horse.internal.domain.com> Date: Fri, 26 Jun 2020 16:54:01 +0200 To: root So i guess(?) that my header_check would test against "To: root" in this case. What would be the best way for me to discard these mails? Note, i cant do it on sender because that would block everything. Thanks in advance
