What percent of overall mail with a partner uses TLS?
The TLS Connections page is divided into a section for incoming connections and a section for outgoing
connections. Each section includes a graph, summaries, and a table with details.
The graph displays a view of incoming or outgoing TLS-encrypted and non-encrypted connections over
the time range you specify. The graph displays the total volume of messages, the volume of encrypted
and unencrypted messages, and the volume of successful and failed TLS encrypted messages. The
graphs distinguish between connections in which TLS was required and connections in which TLS was
merely preferred.
The table displays details for domains sending or receiving encrypted messages. For each domain, you
can view the number of required and preferred TLS connections that were successful and that failed, the
total number of TLS connections attempted (whether successful or failed), and the total number of
unencrypted connections. You can also view the percentage of all connections in which TLS was
attempted, and the total number of encrypted messages sent successfully, regardless of whether TLS was
preferred or required. You can show or hide columns by clicking the Columns link at the bottom of this
table.
