Postfix as gateway

  • 772

I followed this guide verbatim:
http://www.postfix.org/STANDARD_CONFIGURATION_README.html#firewall

However, it results in local mail to root going to [email protected]. If I change that line in /etc/postfix/virtual to: root [email protected] then it gets to me, so problem solved?

The problem is that anyone from outside can also send to root and it gets to me. I've been trying to figure out how to have locally posted mail to root go to [email protected] while preventing outside connections from doing so.

  1. Nevermind, I figured it out. Basically, it's the following that will allow locally posted mail to be accepted, while rejecting the same mail from outside...

    In main.cf:

    smtpd_recipient_restrictions =
    permit_mynetworks
    check_recipient_access hash:/etc/postfix/recipient_access
    reject_unauth_destination

    In /etc/postfix/recipient_access:

    [email protected]  REJECT

    Activate it:

    postmap /etc/postfix/recipient_access
service postfix reload
