Hi Victor, Mouss,

The most important thing for us is a protocol that deals well with high
latency connections. SMTP is not what we need ("hello?", "yes", "would
you like an email?", "sure why not", "are you feeling fine today?", "of
course", "well how about one email?", "yeah I can deal with that", etc etc).

Those kind of conversations over high latency links are really expensive...

Other things we don't want is DNS lookups, email deliveries to the
Internet etc... what we do need is the ability to just to throw a
"bucket" of all pending emails both ways, then disconnect and the MTAs
on both sides will sort out the email at their convenience.

There's no need to worry about the privacy of the channel since all
traffic goes thru an encrypted and compressed tunnel.

I guess UUCP would be the way to go (but must admit I need to read up on
it)... or would you recommend to also study BSMTP (haven't worked with
BSMTP either).

cheers,
Jan
