Mail rely question

[robmorin]

Hello all...

I have a 2 servers that are running Postfix version 2.3.8-2 on Debian Etch and accepts mail for a couple hundred domains, all works just fine now. One server is simply my MX, it just scans email and then delivers it to either my pop server for my virtual hosts or it relays the email to other clients that have their own pop server. My problem is, if that the clients i only scan mail to and then relay to, if they come onto my pop server(also my webserver where Omega resides) to use webmail the emails they send to their domain get delivered locally rather than go out to their own servers.... this of course would seem normal as i have entries like so...

As the control panel for these domains resides on the same server(pop & web) so any email originating on this server gets delivered locally....

In my main.cf i already have relayhost = [xx.xx.xx.154]

I figured all email would be redirected to that server, but it seems not if it is seen as local....

how can i have domain.com which is a relay only client relay to their own server
