Hi,

I am experiencing an issue with Thunderbird which is blocking me from sending any emails from the desktop version (pic attached). I am able to read and receive emails just fine. The web version of Thunderbird works fine as well. This error happend after I upgraded the Thunderbird to the last version and since then I am unable to send emails.

The error says this (I translated it from czech):

The certificate key is not sufficient for the requested operation. Configuration related to IP address must be repaired.

Do you know what could be causing this issue? Thank you in advance.

T.

Většinou - pokud něco v Thunderbirdu nefunguje po aktualizaci, je řešením návrat k předešlé verzi. Všechny verze jsou ke stažení tady: http://ftp.mozilla.org/pub/thunderbird/releases/
