I am now receiving this message when trying to send email: “Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.telus.net was lost in the middle of the transaction. Try again.” I can receive mail a-ok but I can no longer send. This issue started all of a sudden without any changes to my settings & seems to coincide with Thunderbird update 78.13. Last email I was able to send was Aug 14th. Server Name: smtp.telus.net Port: 465 Authentication method: No authentication Connection Security: SSL/TLS Thunderbird 78.13.0 Windows 10 with Windows Security I’ve tried: - Deleting saved passwords (tried this multiple times) - Previous versions of Thunderbird & 91.03 - Different configuration settings for Outgoing Mail Server (as suggested on Thunderbird support page) Any help?
