I have had Thunderbird installed on my Windows 10 computer for a long time and have experienced few difficulties, none for a year or so including no SMTP email sending difficulties using Spectrum’s mail.twc.com. I have the latest version of Thunderbird.
Nevertheless, when I sent several emails successfully and immediately tried to send another one, the send failed. I had made no email account changes at all—same setup as before.
Emails will send through web mail, but I much prefer using Thunderbird.
Here are the SMTP settings that have been in place for a long time: Description: AT&T; Server name: mail.twc.com; Port 587; User name: [my full and correct email address]; Authentication method: Normal password; and Connection security: STARTTLS.
I tried some changes a friend suggested to see what might happen—changing connection security to SSL/TLS and then to none, switching port to 465—but no improvement occurred.
This is the error notice that appears:
“Send Message Error
“Sending of the message failed.
“The message could not be sent because connecting to the Outgoing server (SMTP) mail.twc.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) are correct and try again.”
I should mention that I have a Gmail account run through Thunderbird, which works fine (of course it has a different outgoing server). I also have waited a couple of hours to see if this might resolve itself, but it hasn’t done so, and I rebooted the computer, no change. If I call Spectrum, they undoubtedly will tell me it is Thunderbird’s problem.
What to do to resolve this?
