Use SMTP with authentication or TLS Authentication in JON

Issue

• We have modified the parameters rhq.server.email.smtp-host, rhq.server.email.smtp-port and rhq.server.email.from-address in rhq-server.properties, but we must also insert a login/password authentication. How we can insert the login/password for the SMTP server?
• How can I configure the JON Server, to send alerts via email, using an email server on the cloud, which use TLS Authentication.
