Default Postfix Mail relaying config Fedora 4

Hi there,

I used this tutorial to set up a spam and virus filtering mail gateway on Fedora 4 core. The tutorial was great, but I am have some issues with relaying to appropriate domains.

I have the following in

relay_domains =,
transport_maps = hash:/etc/postfix/transport
and my transport file:
Code:   smtp:[]   smtp:[]
Domain1 works pertfectly fine, no issues whatsoever.

Domain2: you can telnet to the server and send mail to it no problem. If I try and send from any mail client( for one) I get a 550 relaying denied bounce.

I am sure you can see why I am a little baffled! I am using a different external connection to telnet in than the internal network, so I know it's not any sort of allowed subnet issue.

I am VERY new to postfix, but any guidance would be greatly appreciated!
