When I see this, it’s because the customer’s email client does not support TLS 1.1 or 1.2…
The last time, for me, it was a Windows 7 PC running Outlook 2007… I had to point the client to the websites that show how to install the latest TLS support onto Windows 7.

Hi folks, I sent an email to a person and got this reply... TLS connect failed: error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol; connected to xxx.xxx.xxx.xxx. Is this error at my end or theirs? -- best wishes Tony White
