Unable to send outgoing email unless on my Cox connection at home
For the last couple weeks, I have been unable to send any outgoing email through smtp.cox.net unless I am actually on my Cox connection at home.
I first noticed this within the last two weeks when I was home (I'm overseas at the moment). From my mobile phone, my outgoing mail would sit in the Outbox and give an "unable to send" error until I would get back home and connect to my home WiFi, then send.
I have tried deleting the account from my mobile phone and setting it back up with the automatic settings. That did not work.
I have tried using both port 587 with TLS and port 993 with SSL on both my Android mobile phone client and my Microsoft Outlook client on my computer. On Outlook, I can at least see an error message that my username/password was rejected.
From reading other posts about this, before you ask me to email details to support, please bear in mind that the entire reason I'm posting here is that *I CANNOT SEND EMAIL*.
