Postfix mail server: send mail to non-local recipients

I can receive mail in my spool from hosted virtual accounts such as gmail, but when I try to send mail out, I get: 550 5.1.1 error: recipient address rejected: Local delivery only!

Below are my main.cf and master.cf stripped of comments.

Re: Postfix mail server: send mail to non-local recipients

Your issue is this one in main.cf:

default_transport = error: Local delivery only!

Change it to

default_transport = smtp

Thanks for that.
That fixes the 550 error.

Now I'm getting 451 error <email@domainname.tld>: Temporary lookup failure when I use telnet after entering a "rcpt" address.

Would that mean my mysql databases are incorrect? I don't think those should matter at this point.

Re: Postfix mail server: send mail to non-local recipients

Looking at the config you posted, you're not using mysql at all.

The error means that the rcpt adress cannot be resolved (either because it doesn't exist, or because there's a network issue).
