Yes this interface seems right... but, and that was my point, you'll
need it in many places.  For example, if you work at 'smtpmail-send-it'
level, you would try to make 'smtpmail-via-smtp' async and have a
callback for its bookkeeping.  But then, you'll also need a way to add
the bookkeeping of higher level calls (for instance, 'message-send').

I start to see why modifying something to be async in Emacs should be
scrutinize to see if it worth the effort because you'll lose easy
programming and compositing in the process.

Anyway, I'll keep trying for the SMTP sender.
