With your directions, I focused on SSL, port, and rr requirement. I stepped into the "server requires authentication". I used to have this enabled and no SSL for Verizon. Now with this disabled and no SSL, it works. This is very surprising to me. Does this mean anyone in the world can point to xxxx-yyyy.tx.rr.com and use the rr mail server exchange to send email out? Wow, what a loophole in rr. The problem now is spammer can use this path to send spam email with blessing from TWC Road Runner. This will disguise well to other mail servers to accept spam.
Thanks, without your directions, I would not be able to focus and fix this.
I put xxxx-yyyy to cover up the real route to avoid spammer to see this. If you have previlege, please change my original message path to xxx-yyyy
