How to set the sender of the current Mail.app outg

Question

I'd like to write an AppleScript to set the sender of the current outgoing message in Apple's Mail.app.

I've tried this:

tell application "Mail" to set sender of front outgoing message to "<my email address>"

but I get the error message error "Mail got an error: Can’t set sender of item to any." number -10006 from sender of item to any which doesn't make sense to me.

When I try to interrogate the front outgoing message as follows:

tell application "Mail" to get properties of front outgoing message

I get {class:item} in return, instead of an "outgoing message" object like I'd expect.

Any ideas?

Actually you can set the sender of an outgoing message as described here: Incorrect sender when sending Email via Applescript
