'Getting an "Unable to convert connection to SSL (javax.net.ssl.SSLHandshakeException: Received fatal alert: protocol_version)"

I have configured an email notification using Javax.mail with the following properties:

mail.smtp.host=mail.mycompany.com
mail.from=Notification Email <[email protected]>
mail.smtp.auth=false
mail.smtp.starttls.enable=true
mail.smtp.starttls.required=true
mail.smtp.ssl.protocols=TLSv1.2
mail.smtp.port=587
mail.smtp.ssl.trust=mail.mycompany.com
mail.smtp.debug=true

But I'm receiving the following error:

  javax.mail.MessagingException: Unable to convert connection to SSL (javax.net.ssl.SSLHandshakeException: Received fatal alert: protocol_version)
