I'll send it to the emacs people.

Message uses sendmail, smtpmail, feedmail, qmail etc to send mail.
Message could have key bindings that binds the mail-use-dsn to
something within the current buffer.  OTOH I think it is rather
unclean as it only applies to one method for sending mail.  So maybe
it is better to only have the sendmail.el variable?  And use M-x
set-variable.  Or using posting styles.  Or hooks.  Sendmail.el could
provide functions for setting the variable, but it is such a simple
function so maybe the variable is sufficient.
