I have just "flipped the switch" for ZCS this weekend. I'm receiving messages fine and I can send them from within the mail client. However, previously I had all messages forwarding to my gmail account to use as an archival system (will be changing to Enkive in the future but for know I want to setup the same). I also have/had GMail setup to use my current server as the SMTP server to send from so it looked like any messages that I send from within GMail are from my server.

So I have 2 questions:

1. How do I setup a forwarder? I want to automatically forward ALL messages received to GMAIL?

2. I sent a message from GMail and it bounced back with the following message: 500 Remote server does not support SMTP Authenticated Relay

How can I fix #2?
