TLS-Encrypted SMTP Connections

TLS-encrypted SMTP connections are not scanned by the DLP Software Blade Specific security solution (module): (1) On a Security Gateway, each Software Blade inspects specific characteristics of the traffic (2) On a Management Server, each Software Blade enables different management capabilities.. If an Exchange Server uses TLS to encrypt emails, you can use the Exchange Security Agent to inspect them (see Configuring the Exchange Security Agent).
