It isn't entirely a matter of choice -- most modern MTAs like your own
only trust certain users to set the From: address. As such, most
ordinary users aren't in a position to do this in order to assure

of inserting a Sender: line if the From: has been set and otherwise
permit arbitrary munging of the From:
