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

Has anyone run across this error on the wrapper logs:

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

Trying to set up a new SMTP connection but having trouble getting it to work. Any info would be much appreciated!

I think this means you’ve configured the connection to use SSL/TLS but you’re connecting to a server that either doesn’t support it at all, or doesn’t support it on the port you’re using. There’s usually a separate port (465) for SMTPS.

Thanks Kevin! I’ve unchecked the boxes. That cleared up the error.
