Cannot send e mails

Thunderbird 邮件服务与邮件

Whenever I try to send an e mail or reply to an email I get an error message telling me that the Connection to the Outgoing Server SMTP was lost in the middle of the transaction. I have check with my ISP (Telstra Australia) and there is no fault at their end. The account settings in Thunderbird are correct and I have the latest version. I can receive e mails but cant send any. This problem has only occured in the last couple of days. Can you help please.

Try to start Windows 10 in safe mode with networking enabled.

Still in Windows safe mode, start Thunderbird in safe mode. Does the problem go away?

Windows safe mode disables anti-virus software. This is a troubleshooting step, not a solution.
