Whenever anyone tries to send mail through my server using SMTP it fails with the following message

The connection to the server has failed. Account: 'username', Server: 'mail.domain.com', Protocol: SMTP, Port: 25, Secure(SSL): No, Socket Error: 10061, Error Number: 0x800CCC0E

The port is open in APF, server requires authorization is checked...
Also tried username@domain.com and username+domain.com which still failed.

Ran
/scripts/exim4
/scripts/fixpop
/scripts/mailperm
and even
/scripts/fixeverything

and it still says the same thing.
This is on a new RHE 3 cPanel 9.1.0-S93... I keep reading posts about this problem but no fixes (that work for me).

Any suggestions, I'm game to try anything to get this working correctly...

This error typically means port 25 outgoing is blocked by your ISP, check port 26 instead.

Use your ISP's Main SMTP server. Cox blocked all Out Going SMTP unless it is their own.
