One long-established email account now won't send
I have two long-established email accounts, both provided by siteground. I've used both successfully for years. Now, one still works for sending and one doesn't. I've checked the SMTP settings for both and they are the same, except of course for Description and Server Name. Here's the error message I get.

Server names can be very important. Share screenshot of the SMTP server setting pane of the good one and the failing one, identifying which is which.
In your prior post, you stated that this one did work. I'm confused. Have you spoken with siteground? That may be your next step.
That you posted it worked in prior post and now you post that it doesn't and that, despite stating you use siteground, you have yet to pursue with them.
My first post in this thread said that one does not work. I will ask siteground, but they are not much help with Thunderbird users.
I know nothing of Siteground, but that they recommend email settings with no security is in conflict with what most all other email providers require. Normally, I would suggest a different port, SSL/TLS, etc. I wish you well. If you do get a response and update on settings, please share. And, Merry Christmas. :)
This link may help. https://www.siteground.com/tutorials/email/mozilla-thunderbird/ the settings seem different from what you are using.
Thanks. I'll try those recommended settings later. However, I'll again note that the email account that works (sending) has the same settings as the one that doesn't work.
Dyrbiće so pola swojeho konta přizjewić, zo byšće na přinoški wotmołwił. Prošu stajće nowe prašenje, jeli hišće wužiwarske konto nimaće.
