I'm using Google Apps to handle personal email addresses for my domain name, and I set up the DNS as Google suggests. All works fine.

Now since I need a SMTP to send emails from my e-commerce I installed Postfix on the server. It works fine when I send emails to any email address but it doesn't send to the same domain name, so let's say my domain is, I set postfix using, if I try to reset a password using postfix doesn't send and instead reports on the mail.log

Of course it cannot find a local user "myaccount" since that account is on Google Apps...

How can I tell Postfix to send the email and do not search for a local user?

This is called "Postfix as a null client" and is extensively documented on their homepage:

As you can see in the Url it even is one of the STANDARDS.

You are not allowed to tell Postfix to be responsible for because it is not. Google is responsible for the domain.
