Suddenly my Thunderbird stop receiving email. Top left corner - blue rotating cycle is signalising synchronisation, It never stops, there is no error message appearing.

1) I am using three different e-mail servers (gmail, wedos.cz, post.cz) - none of them works 2) I can send emails, but they cannot be saved to mail server 3) I tried to reinstal Thunderbird - did not help. 4) Yes, I tried to restart Windows - did not help. 4) I tried to turn off Firewall (ESET) - did not help.

Any ideas how to fix it? Thanks

Chosen solution

  • 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

V Thunderbirdu je patrně potřeba změnit předvolbu: security.tls.version.enable-deprecated na true.

Díky moc, to jsem nenašel.

Pomohlo zapnout a vypnout SSL zabezpečení v rozšířeném zavezpešení v nastavení ESETU.

or ... temporarily disable SSL in ESET until they solve the problem per https://support.eset.com/en/kb3126-disable-ssl-filtering-in-eset-windows-products?ref=esf - the problem is being reported by dozens of users https://forum.eset.com/topic/26517-problems-with-thunderbird-and-imaps/ https://forum.eset.com/discover/
