To: from command line

[John Velman <velman@xxxxxxx>]

I'm interested in invoking mutt from the command line to send
a message.  (More generally, I'm interested in making Mutt the email
application invoked by Firefox when I click on an email address, but this
seems like it could be one step toward that.  Might also come in handy
other times.)

Invoking as "mutt -c someone@email" does the trick, in a way, but the
address ends up on the Cc line, with the To line empty.  This seems to
work, but certainly looks strange.

Is there a command line option for the To line?

Thanks,

John Velman
