Blackberry/Gmail configuration

I need to know how to setup a Blackberry 8830 in such way that I can receive emails from Gmail but when I reply the 'From' is set to my vanity domain. I have set it up correctly on the PC and Web but the Blackberry insists on setting the From to my gmail address. I need to be able to reply to messages, so, simply setting up a separate inbox does not solve my problem. ## Deliverables **No code, just send me the instructions.
