Hi,

Since update to Thunderbird I cannot send messages. I get the error message in attached screenshot.

Screenshot of my SMTP settings attached.

Mail provider: TPG ISP: TPG Firewall version: Windows Antivirus software and version: AVG Antivirus Free 20.7.3140 (build 20.7.5568.597) Operating system and version: Windows 10 Thunderbird version: 78.2.2 (32-bit)

Thanks, Brad

Chosen solution

change startTLS to none and see how that goes. My understanding is TPG actually suggest no connection encryption.
