Why does Postfix deliver mails locally instead of relaying them to Google Apps?

I get the following error trying to send an email to my Google Apps Email at admin@mydomain.com from my Postfix server.

to=, relay=local, delay=0.09, delays=0.07/0/0/0.02, dsn=5.1.1, status=bounced (unknown user: "admin")

Is there a way I can force it to not use the LOCAL relay and treat admin@mydomain.com as outside email and not look for a user in the current postfix configuration.

I am trying to email the full email address "admin@mydomain.com" not only "admin".

I have the Google Apps MX record on mydomain.com + SPF record which before was:

v=spf1 include:_spf.google.com ~all (emailing to admin@mydomain.com used to work with that record)

But I had to change it to v=spf1 a mx ip4:MY.IP.HERE include:_spf.google.com ~all
