[Discuss] Verizon blacklisted me

Actually, my Linux box (behind the FIOS router with the blacklisted
IP) does send all its mail through Verizon's SMTP server
( port 465) as a relay host. Well, to be more
accurate, since postfix doesn't support outgoing email on port 465, my
mail goes from postfix to stunnel on localhost:

  # Postfix
  relayhost = []:10465

and stunnel then talks to on port 465:

  # stunnel.conf
  accept =
  connect =

But that be transparent to, right? This setup has
worked fine for months....

That's what I thought too. It certainly didn't matter until last week,
when (I hypothesize) Verizon changed my router's dynamic IP address to
that of a blacklisted spammer.
