Two days ago Thunderbird no longer would send emails (been using it without problems for 7 years) I have read all the previous posts on this. Tried sending emails after disabling firewall and Malwarebytes without success. I can receive emails sent from my Spectrum email account (still works). I can send emails from my iPhone using the identical Outgoing Server Settings. The settings are in the screenshot. Also downloaded the latest version of Thunderbird today. Didn't fix it. To get around the problem right now is I am composing my emails (IMAP), saving them in my drafts and then sending them from my iPhone.Any ideas? Thank you!

I can't be exactly sure but this problem occurred right around the time that Thunderbird was updated to Version 102.13.0. Would returning to the previous Version 102.12.0 solve the issue? Thanks

Good idea, but 102.13.0 had zero changes which would affect this. Specifically, https://bugzilla.mozilla.org/buglist.cgi?bug_id=1833657%2C1794180%2C1836634&list_id=16714067

You might trade for different problems, but one option to you is to update to 115 using Help > About. 115 has it's own (we hope rare) timeout problem https://bugzilla.mozilla.org/show_bug.cgi?id=1801668
