Question : Exchange 2007 Mailforward to external Address

I know there are a lot of Google results on this question, but none of them actually solved my problem.

We are a hosted exchange provider and our customers want to forward their mail to some external addresses (like gmail). I can easily do that with a transport rule, but that is not the point. The customer should be able to enable/disable this by himself.

What i've done/tried so far:
- User created a rule in OWA (or Outlook for that matter) which should forward incoming Mail on certain conditions to his external account (i.e. Gmail Account)
- internal target addresses work fine
- I have added the external address to the Global Address List

Exchange still does not forward the message. If I check Message Tracking Logs, I see the "RECEIVED" entry for that message on the Hub Transport server. But no "SEND" event is listet and it looks like the Server just ignored the mail.

Any help appreciated!

Sorry - I noticed that only after posting. My bad.

Don't you need to allow automatic forward?

In the Exchange 2007 console -> Organization Configuration -> Hub Transport

In the remote domains tab, open the properties for your Default domain and check Allow Auomatic Forward.

From memory though, so could be wrong.
