I had hacker problems. And I had to reinstall Windows 10, FireFox, and ThunderBird. I then tried to send an E-Mail. And I received this error message:

Sending of the message failed. Peer using unsupported version of security protocol. The configuration related to smtp.iinet.com must be corrected

I have checked the SMTP server is correct. I also check the Port too. I tried port 465 and it timed out. I tried port 857, and got the error message. And now I don't know what to do next.
