[Discuss] Verizon blacklisted me



Last week without warning, all my outgoing FIOS email started getting
rejected by Verizon's SMTP server, smtp.verizon.net, with this error:

  500 5.7.0 Unknown AUTH error -1 (Internal authentication error)

I looked up "500 5.7.0," and it means my IP address has been
blacklisted. (For no reason that I can imagine.) No client changes
happened on my end to cause this.

Has anyone else ever experienced this and gotten it fixed? The Verizon
support people I've spoken with don't seem to have the knowledge to
understand a server-side problem like this. They keep asking if I can
log into their webmail server, what my Outlook settings are,
etc. Eventually they check with some mysterious "email server team,"
who claims my IP address is not blacklisted... and yet
smtp.verizon.net is giving me the above SMTP error "500 5.7.0" every
time.

In the meantime, I have signed up with a different outgoing email
provider, which is why I could send this note. :-)

Thanks for any tips...!
