Would be very nice to have a good answer to this one, as I hope we can
get these systems to send email to each other. :)

I created a debian package exim4-smtorp to configure exim to use SMTP
over Tor for all *.onion addresses, and the result can be seen from
<URL: https://github.com/petterreinholdtsen/exim4-smtorp >.  It seem
to work for me, but I've only tested on one machine so far.

If you want to test it yourself, by sending email to my test machine,
install swaks and run this command:

  torsocks swaks --to fbx at dutlqrrmjhtfa3vp.onion \
    --server dutlqrrmjhtfa3vp.onion

This send the email to Exim and local delivery via Tor. :)

Happy hacking
