Thunderbird: форум сообщества

I keep getting a certificate error on my Thunderbird. The certificate refers to an email account i no longer have (Personal domain) and i have removed the account in thunderbird, and also removed previous certificate exceptions.

I have been through all menus and settings, and cannot find anywhere where it refers to that domain (and subdomain) I have also removed one entry with that FQDN in the outgoing server section.

What to do?

Hello, My SMTP server uses Let's Encrypt certificate. The website with the same domain has no certificate. Thunderbird refuses to connect to my SMTP server. Test connection to the server (STARTTLS) in account settings sais "The secure connection to the server failed" (or similar. I see bg localization). Another server with Let's Encrypt certificate. Test pases. Clicking View certificate shows webserver cert (from DigiCert Inc).

I can't send emails! :)
