Thanks for everyone who's replied so quickly-- I've actually found out
what /caused/ the problem. Apparently using SMTP to any hosts outside
Cambridge is not allowed, and they've had a firewall in for a number of
years; the question I want answered is how the f*** did I mange for two
weeks without using their smarthost?
Anyway, that's by the by-- my next question is how can I set qmail so that
it has the envelope address permanently set to <[EMAIL PROTECTED]>, whoever
the mail comes from on my machine? I managed to run a mailing list from
my Acorn machine in this way, but I'm not sure how to fiddle the envelope
address with qmail.
