Spooling mail Question
I am running postfix as a SMTP front-end to my Exchange 2007 system. When Exchange goes down, email is bounced back to the sender as undeliverable.

(SOLVED) Routing (relaying) an unknown Domain
Ok...I wasn't seeing it but it was simple. The /etc/postfix/transport is correctly configured.

I'm using chroot environments as a form of virtualization of two mail systems. The main system has a basic ethernet interface eth0 with IP0 and two aliases: eth0:1 and eth0:2 with IP1 and IP2.
