User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:39.0) Gecko/20100101 Firefox/39.0 Build ID: 20150630154324 Steps to reproduce: Thunderbird 38.1.0 on Linux Desktop. Configure outgoing SMTP/S server with SSL/TLS, cleartext password. Compose message. Press Send button. Actual results: Popup appeared saying "Connected to <SMTP server>". (<SMTP server> was name of configured outgoing SMTP server.) The a second popup appeared, saying twice "Senden der Nachricht fehlgeschlagen.Die Nachricht konnte aus unbekannten Gründen nicht über den SMTP-Server <SMTP server> gesendet werden. Bitte kontrollieren Sie die SMTP-Server-Einstellungen und versuchen Sie es nochmals." (In English:"Sending message failed. The message could not be sent for unknown reasons. Please verify the SMTP server settings and try again". Thunderbird 34.0b1 (German) works correctly with identical settings. The issue occurs from version 36 on. Expected results: The error message should not appear. The message should be sent.
Issue occurs on German Thunderbird from version 36.0b1 on. Tested with 36.0b1, 37.0b1, 38.0b1, 38.1.0, 39.0b1, 40.0b1
Version: 40 → 38
Version in ticket head changed back to 38 in order to omit confusion while reading first description.
Priority set to P3 as version 34.0b1 can be used as workaround.

Thanks. Note: priority is reserved for developers. And bug meets the definition of "Major" severity per https://bugzilla.mozilla.org/page.cgi?id=fields.html#bug_severity
Severity: blocker → major
Priority: P3 → --
With 38.2 the bug only occurs, if the message is signed. Encryption has no impact.
With 41.0b1 the bus occurs at any time communicating over SMTPS.
41.0b2 hasn't fixed it either.
Neither has 42.0b2.
SOLVED: set security.tls.version.max=1
