Description (partial)

SMTP Traffic using TLS as a transport, over TCP port 25, is not filtered or checked by the Email Reputation System on the Trend Micro Content Security and Control module.

This is seen on all versions of code for the CSC-SSM and only affects traffic that uses TLS (the STARTTLS command) in the SMTP communication.
