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.
Patrick

Wietse,

Does it mean that I did right and it could be a bug?

Thanks

It means that to get a meaningful answer, you should read the page at
http://www.postfix.org/DEBUG_README.html#mail and provide the info
requested.

postfix reload is not needed (I think)
