TLS Connections Report-Incoming Connections
Inbound SMTP Authentication Page
The Inbound SMTP Authentication page shows the use of client certificates and the SMTP AUTH
command to authenticate SMTP sessions between the Email Security appliance and users’ mail clients.
If the appliance accepts the certificate or SMTP AUTH command, it will establish a TLS connection to
the mail client, which the client will use to send a message. Since it is not possible for the appliance to
track these attempts on a per-user basis, the report shows details on SMTP authentication based on the
domain name and domain IP address.
