STARTTLS command: Indicate the ability to negotiate the use of TLS

Purpose

Use the STARTTLS command to tell the SMTP application to negotiate the use of TLS.

Requirement: You must issue an EHLO command before you can issue the STARTTLS command. If you issue the STARTTLS command, it must be issued before you can issue the MAIL FROM command.

When STARTTLS is specified, the scope of the security attribute is set for the mail messages that follow in the JES spool file until another HELO or EHLO SMTP command is issued. See the CSSMTP security details in z/OS Communications Server: IP Configuration Guide for more information.
