Unrecognized SSL message, plaintext connection? Exception


java https

I think this is due to the connection established with the client machine is not secure.

It is due to the fact that you are talking to an HTTP server, not an HTTPS server. Probably you didn't use the correct port number for HTTPS.

java https 

javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?

You should have a local SMTP domain name that will contact the mail server and establishes a new connection as well you should change the SSL property in your programming below 

javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection props.put("mail.smtp.socketFactory.fallback", "true"); // Should be true

java https

I got the same error message when I forgot to log in to the company firewall, before performing a POST request through a proxy.
