I've set up my brother's new MBP to send his email out via his Gmail account... but of course now, all his mail shows as coming "From" his Gmail address. I can put his regular email address in the Reply-To field and it will show, but so far I've only been able to do this on a per-message basis - you have to select the Reply-To field in every new message and enter the address you want.

There has to be some way to set this as a default action for every message? The online help got me to the above steps, but doesn't show me any way to make it a default.

TIA
