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.
