Cannot send outgoing mail from my Spectrum account with Thunderbird

Since I installed Thunderbird on my new computer, I have been unable to send email using Thunderbird with my Spectrum account. I can receive email using Thunderbird with no problem.

I called Spectrum tech support and they confirmed that I can both send and receive email from their webmail app, so the problem is not on their end. They also gave me the correct settings to use for Outgoing mail, which I entered within the Thunderbird Account Settings. I read the articles on the Thunderbird support site, but they did not fix my problem.

My Thunderbird version is 115.12.1.0. My OS is Windows 11.

The attached photos show the failure message I am getting and also the account settings. Please let me know if you have any questions or if you need anymore information.

I really like Thunderbird from my previous experience so I really hope that you all can help me overcome this issue. My wife can send email from her phone but we really want to be able to do it from the desktop as well. Please help!

Thanks, Bruce

sfhowes,

Thank you very much for responding and for your help! That solved it. The Spectrum tech support analyst did not know the correct value for that setting (SSL/TLS vs. STARTTLS), had me switch from mail.twc.com to nc.rr.com, and said my issue was a 3rd party problem. So I really appreciate you setting me straight!

According to Spectrum, the outgoing server for nc.rr.com accounts should be mail.twc.com, 587, STARTTLS.

I've also seen working setups with the same settings except SSL/TLS security, as in your picture.
