My provider supports TLS, but I can't get it to work with TB.
The account logs says :

Code

!27.07.2022, 14:58:25: SEND  - TLS protocol error: Unexpected message SessionUnknownContentType ct (53).
!27.07.2022, 14:58:36: SEND  - TLS protocol error: Unexpected message SessionUnknownContentType ct (50).

Unfortunatly, the 'real' SMTP-log remains empty. (It is not totally empty,
but it seems only to log successfull (non-TLS) sendings).

What can I do to fix this problem ?

(I'm using TB version 10.1 - Professional Edition)

Solution from this is not solving this issue:

Why did you literally copy that 12 year old message?

Have you asked your provider which settings you should use? Or are you experimenting with a mail server of your own, like in your other message?

What are your settings under Account | Properties | Transport | (Send Mail section) ?
