Once someone's email address is blocked as a potential spam error I cannot
send that person anything ever again, regardless if I close outlook, restart
the computer, etc. I have tried obvious non-spam to that person and it is
returned as potential spam. It's like the email address is blocked. I have
checked my email settings and no one is blocked so it is not that either.
I am think it is time to contact the ISP again and try to get yet another
technician (third attempt) and maybe someone different will be willing to
assist because the more it goes the more I think it is them and not outlook
You never identified the domain for the recipient (i.e., to what mail server
you are sending your e-mail). It is possible that the target domain has
been blacklisted by Cox; i.e., they won't send any e-mails to that receiving
mail host. Usually a blacklist is employed for received e-mails from a
known spam source. It is unusual that outbound blocking is employed with
regard to sending any e-mail to some domain.
Is Cox your ISP or is the ISP for the recipient? From *whom* is the NDR
(non-delivery report) e-mail sent? By your own e-mail provider or by the
recipients? If that NDR is being sent by Cox which is the *recipient's*
e-mail provider than they are claiming your mail server is a spam source.
It is then very unlikely that you can get someone else's provider to update
their blacklist since you are not their customer. You'll have to ask your
e-mail provider to work with Cox to get off of Cox's blacklist. Apparently
Cox doesn't care for all the spam coming from your e-mail provider's mail
server.
Are you using some freebie e-mail provider that adds some spam promotional
signature crap to all your outbound e-mails sent through them?
Who is YOUR e-mail provider?
Who is the RECIPIENT's e-mail provider?
Which e-mail provider sent you the NDR e-mail?
