Precisely.

Hi Kilburn,

You'd have thought I would have resolved this by now, wouldn't you...

Sorry for the constant questions...

I set this up, and tested it by shuting down the main mailserver, sending the mail and then switching it back on...
The mail came direct from the originating server (gmail)...

I thought this was odd, so I thought I'd check the relaying, by putting the

domain.tld. IN MX 5 relay.domain.tld.
domain.tld. IN MX 10 mail.domain.tld.

I thought this would test to see if the mail went into the relay and then got forwarded on to the secondary...

But gmail stated "No relay access"...
Thinking about it, surely if I'm commenting the domain from postfix, unless I'm an open relay, it's going to be blocked?
How do I set the server to be a relay, but only for the specific domain?

Thanks again for all your help!

Cheers,

Jx
