I know about the academy; Moreover, when a (receiving) mail server does
not love my sendmail, I use a mail server of one of the universities
(without logging to there). But the original message (which I responded
to) referred to ISPs (read it again) and to dial-up users, so I
reffered to this case, too. Anyway, considering the rise of the
spamming, I expect that even the academy will close its gates and will
deny relaying, very soon.
