I have now contacted Cox No Support five times regarding this matter, most calls involving escalation to Tier 2. I am now 9 days into a promised 1-2 day managerial callback (and reqjuested another one yesterday).
Yes, I've changed my password and reset it for my devices. It makes no difference in the failure to send mail via SMTP. The first time that you try to send a message you get this error :
"Sending of the message failed.
The message could not be sent because the connection to Outgoing server (SMTP) smtp.cox.net was lost in the middle of the transaction. Try again."
If you then immediately try to send again you get this error :
"Sending of the message failed.
The message could not be sent because the connection to Outgoing server (SMTP) smtp.cox.net timed out. Try again."
For whatever reason I am now able to send messages via my iPhone, at least of yesterday afternoon, and at least from within my own home on wifi. Will try again out in the real world later today. But the problem continues for my laptop running Thunderbird.
For the record I use this same Thunderbird installation to manage seven (7) e-mail accounts, only one of which is with Cox. None of the other accounts are having any issues with either POP or SMTP.
What's your Timeout setting? Perhaps you could try increasing it.
Bruce, thanks for the suggestion. Obviously I don't believe that this is something that users should have to tinker with because of ill-advised changes made by TPTB, but what the heck. I went in and doubled the default timeout from 100 to 200 and re-started T-bird. No joy, same error. I then increased it to 500 with another re-start; same result. I get the distinct impression that the lights are on but nobody's home at the SMTP server ...
Still no solution, 15 days and counting ...
