On my Thunderbird for Linux, I suddenly can't send messages due to "login to SMTP server failed". This happens even though:

- it worked until yesterday - I can receive messages - I can send messages on my other account (on another SMTP server) - on my Thunderbird for Windows (with exactly the same SMTP server settings - login, password etc.) everything cotinues working fine as usual

What could be the problem?

Asi došlo k zmene SMTP nastavenia u toho jedného účtu. Prepnite sa na (nastavte si) SMTP vášho poskytovateľa internetu.

Hodně problémů v posledních verzích Thunderbirdu způsobují antiviráky Eset Security a Avast. Zkuste to povypínat, možná raději odinstalovat - zvláště ve Windows 10.

Dále viz. support.mozilla.org/cs/questions/1316084

Dík, ale tyto antiviry nemám a ve Windows mi to právě funguje. Nefunguje to v Linuxu.

Zkus v TB nastavit security.tls.version.enable-deprecated na true
