Sending of the message failed.

Hi uluvit13.

A moderator produced this article for Thunderbird.

https://community.tpg.com.au/t5/Broadband-Internet/Thunderbird-ver-78-1-1-and-above-Troubleshooting/...

You'll notice near the end that SSL is set to NONE, so all communication is not encrypted. Thunderbird v78 has deprecated SSL/TLS below TLSv1.2. 

If you want to use encryption, have a look here:

Read through the whole lot but take note at the end from David1010. I don't use Thunderbird so I can't comment on it.
