Interesting!  I like it.

Nitpicks:

 - I think it would be good to call the envvar XDG_MAILER, because
   (1) the mailer for use in the console may not be the mailer to
   use on the desktop, and (2) it would be nice to leave open the
   possibility of a MAILER variable along the lines of BROWSER with
   more useful semantics in the future.

 - What happens if the mailer contains shell metacharacters?
