Hi Santoshi,
There are two areas in which TLS support was added, for SDM - mail:
TLS support for inbound emails
pdm_maileater_nxd now supports connections to mailboxes over TLS (secure connection)
Supports Base64-encoded certificates
Mailbox detail page accepts the “Use TLS” flag and the Trusted Root “CA Certificate Path” as inputs
TLS support for outbound emails
pdm_mail_nxd now supports connections to SMTP servers over TLS (secure connection)
Supports Base64-encoded certificates
Two new options (“mail_smtp_use_tls” and “mail_ca_cert_path) in the Options Manager control the TLS settings
This was discussed in the 12.9 Overview and Demo webinar. Here's a link: https://communities.ca.com/message/241713155#241713155
