I'm not connecting to an open relay. When I pay for service at the =
local
internet caf=E9, part of what I get for my money is time on their SMTP =
server.
..ditto when I pay for cable modem, as I am doing right now. My cable =
modem
provider is cablespeed.com and SMTP server is mail.cablespeed.com. As =
far
as I know, it's available only to its legit subscribers. However, at the =
end
of the month, I'll be signed up with a different cable modem provider. =
That
relationship will last a couple of months, and then I'll be with a =
different
one. Each of these is legit. None is an open relay. But, I don't want =
to
send change-of-address notes out to all my friends every time I change - =
so
I receive through (and identify myself via) a remailer at acm.org.
