[qmailtoaster] Qmail relay

[Randy Gordey]

If I have a MX record with a president of 20 pointing to a Qmail toaster on my DMZ.   I also have a MX Record with a lower a priority of 10 where the host resided inside my secure LAN.   Let’s call my DMZ Qmail server- Mail Server ‘A’ and my Secure LAN Qmail server – Mail Server ‘B’   Server ‘B’ is secured by a firewall and is limited to accepting inbound connections only from Server ‘A’   (Internet source SMTP Mail) => (Server ‘A’) => (Server ‘B’)   I can get this architecture functioning at a basic level. My only hang-up is I would like Server ‘A’ to filter incoming email (i.e. spamassassin & a valid recipient check) before forwarding the mail onto Server ‘B’. I can get forwarding to work with no filtering done and I can filter without forwarding the email to another server. But I can’t seem to get them booth working at the same time. I either deliver locally after filtering or I forward and entire domain’s email blindly.   Any suggestions anyone might have would definitely be appreciated.         Thanks in advance for your time.   ~Randy Gordey
