SMTPTLSRequired

To allow PeopleTools to issue the STARTTLS or STLS command to the mail server to secure an insecure connection, and require that the mail server support the command, add this parameter manually to the PSAPPSRV.CFG file and PSPRCS.CFG file in the SMTP settings section, and set it to Y (yes).

Use this to specify whether using STARTTLS or STLS is required. If this property is set to Y, mail will be sent only if STARTTLS or STLS is supported on the server. If the server doesn't support these commands, or the command fails, the connect method will fail.
