You'd be amazed. :-)

Very few providers seem to support UUCP these days, at least in South
Africa. Even UUNET SA, the last standing UUCP provider in South Africa,
stopped a while back (so I'm told by an ex-employee).

And POP3 quite simply blows goats. It's certainly no _better_ than
SMTP, and a darnsight worse at handling mid-transaction disconnects,
unless you operate in slow-and-cautious mode, in which case it's worse
in terms of performance. :-)

What I really want is compressed POP3, but why on earth would you
develop such a thing when you could just use UUCP? :-)

I'll do it either way, as long as the customer understands the
implications.

Ciao,
