You are, but going the wrong way 8^)

mydestination is for e-mail that you are going to deliver locally.

relayhost is what is the next hop for e-mail once it leaves your box -
it is the equivalent of smarthost from sendmail.

I would leave both blank, as you don't want to deliver any e-mail
locally and you want your box to deliver the relayed messages itself.

That being said, I have not implemented a setup like yours, so others
might want to chime in.
