I am in Las Vegas, NV and today I can't send email with Thunderbird and keep getting the error message that sending message failed because smtp.cox.net is unavailable. I have used this service for years without any problem. The website https://www.isitdownrightnow.com/ could not connect with the server either. I am getting mail all right. Customer service could not help.
you won't send from a 3rd party, if you're using hotel/similar wifi.
Guess what. Right after I posted my previous reply, pop.cox.net started working just fine. Since everything at my end has remained the same, common sense tells me that the problem is with COX. Hope my luck holds.
I am using Thunderbird on a Windows 7 laptop from my home. Since last monday I had been unable to send mail because smtp.cox.net was unavailable. Yesterday I tried pinging it and it too failed. Then after a few hours I pinged again and this time it responded. I then sent a test mail to my own address through TBird and it worked. Great, I thought, the system has corrected itself but then receiving email stopped. The program would say connecting to pop.cox.net and then stop. I have used this service for many years and while there had been a few temporary outages with smtp, it had always self-corrected within a few hours and never with pop. Sending/receiving mail within myemail.cox.net has worked fine. Another funny thing, when smtp started working and pop was still working, a bunch of old emails also got pulled.
