# transport_maps
tehnews.com  error:5.1.2 not a working domain

I really like the idea of creating a 'transport_map' so I verified my
/etc/postfix/transport directory existed and read the docs. I show
that 'transport smtp' is the default so I opened the transport file
and added the following line:

tehnews.com       error:5.1.2 not a working domain

I then saved the file and ran:

postmap /etc/postfix/transport

I really didn't see if I needed to specifically squeeze the
'transport_maps' parameter in a specific area in 'main.cf' so I
appended to the very end of the file as you can see from my new
Postconf -n below:


The order of parameters in main.cf is irrelevant; put it anywhere convenient. "postconf" always displays parameters in sorted alphabetical order regardless of main.cf order.

I tested this and it appears to give an immediate delivery failure
with reason. Does this look OK to you guys?

Looks as if everything's just dandy.

Peace.
