undelivered mail return

[vs_isp]

Hi again,
Unfortunately, this method didn't help. Still the email is bouncing back to local mail server. It is really strange cause actually i have managed to remove domains from the config and make any further changes but yet it is not sending anything. The bad thing is that i really need google apps for certain domains and it is really sad that there is no actual switch to disable the local delivery. I have searched through other forums/faqs about that particular problem and a lot of people are saying that it has to do with the main.cf file and the "mydestination" attribute. Any other suggestions? Any help would be appreciated.thanks!

So, i made some changes to the main.cf file as suggested in serverfault. At "mydestination" line i made the following edit:
"mydestination = localhost.$mydomain, $mydomain"
So now postfix sends to the google apps account that is under the same domain as the server hostname.
All other domains still not receiving anything. Is there a way to edit main.cf for multiple domains in order to make it send email to other google apps account(different domains in the same server)? Is there an easy way to make postfix understand that some email accounts are handled externally?
