Hi,
I am managing my emails on 2 Postfix 2.7 servers.
A front smtpd server receives all messages from outside and inside
users, and a back server handles email boxes for local domains deliveries.
I am trying to send directly messages from the front smtpd to the back
server without looking to MX from DNS.
So, in the /etc/postfix/transport file, I put lines as follow:
example1.com :[10.0.0.2]
example2.com :[10.0.0.2]
example3.com :[10.0.0.2]
example4.com :[10.0.0.2]
exampleN.com are domains to relay directly to internal server 10.0.0.2
without looking to DNS (using brackets).
I have run postmap transport and postfix reload.
I made some simple tests puting mails through a telnet to port 25 of the
front server.
It still lookup for MX for domains exampleN.com and delivers through an
outside address. If I set this MX to be the smtpd front server, I wonder
what will happen. At least, not what I want.
I made something wrong, but what?
Thanks for help.
