I get this message when I try to send out emails:
Det gick inte att skicka meddelandet. Ett fel uppstod när e-post skulle skickas. Servern svarade: [M5] Your credentials have been compromised. Please change your password or contact support (2fe59c46-0669-11f1-a827-e90f2b8e16ca). Kontrollera att din e-postadress är korrekt i dina kontoinställningar och försök igen
I changed password, and it changed to this:

Suppose I see 10 incoming emails on my server (core.com). In thunderbird, when I click to download them, I see a message saying something like "downlaoding 10 emails". After that only 2 or 3 of them have been downloaded, the rest deleted. Help! This started happening a couple of weeks ago. I have tried downloading and re-installing Thunderbird, to no avail. Should I change my account settings?
Thunderbird is not responsive when I click on it to open my email.

I am experiencing persistent issues configuring a custom-domain email account in Mozilla Thunderbird, while the same account works correctly in Outlook and in webmail.
Environment:
Email client: Mozilla Thunderbird (latest version)
OS: Windows
Mail hosting: Antagonist / DirectAdmin (shared hosting)
Domain: s23k.com
Email address: jean-paul.sablerolle@s23k.com
Incoming mail (POP):
Server: mail.s23k.com
Port: 995
Security: SSL/TLS
Authentication: normal password POP connection works without errors.
Outgoing mail (SMTP):
Server: mail.s23k.com
Ports tested: 465 (SSL/TLS), 587 (STARTTLS)
Thunderbird fails to send mail with the error:
“The requested domain name does not match the server’s certificate.”
Even after explicitly adding and permanently accepting the certificate exception, Thunderbird continues to reject the connection.
Important observations:
Webmail (Roundcube) can send mail successfully.
Microsoft Outlook can send mail successfully using the same SMTP server.
Thunderbird never completes SMTP authentication because the TLS handshake fails on hostname validation.
The certificate presented by the server appears to be issued for a different hostname than mail.s23k.com.
As a workaround, I am currently using an external SMTP server (KPN: smtp.kpnmail.nl), which works correctly in Thunderbird.
Question: Is Thunderbird intentionally stricter than Outlook regarding TLS hostname validation for SMTP, and is there any supported way to:
properly override this hostname mismatch for SMTP, or
diagnose whether this behavior is expected and unavoidable with misconfigured server certificates?
I would like to confirm whether this is expected Thunderbird behavior or if there is a configuration option I may have missed.
I am not trying to weaken security; I want to understand whether Thunderbird allows any safe override in this scenario or if the server configuration is fundamentally incompatible.

I was working with thunderbird today. Was in a specific email folder I had named "reference" that I use to store various emails, probably around 50 emails in there. Suddenly they all deleted from the folder as I was watching the screen. Checked spam/trash folders and nothing. Also logged into my webmail provider and nothing there either. Any idea what could have happened here? They just seem to have literally vanished. Have used Thunderbird a number of years and never experienced anything like this.
