Incoming vs. Outgoing Messages
Two policy tables are defined in the Email Security Manager: one table for
messages from sending hosts that are stipulated by HAT policies with the
“Accept” behavior, the other table for sending hosts qualified as having HAT
“Relay” behavior. The former table is the incoming policy table, the latter is the
outgoing policy table.

Note
In certain installations, “internal” mail being routed through the Cisco IronPort
appliance will be considered outgoing, even if all the recipients are addressed to
internal addresses. For example, by default for Cisco IronPort C10/100 customers,
the system setup wizard will configure only one physical Ethernet port with one
listener for receiving inbound email and relaying outbound email.

For many configurations, you can think of the incoming table as Public, while the
Outgoing table is Private, although both could be used by a single listener. The
policy table used on a particular message is not dependant on the direction of the
message, with respect to sender or recipient addresses, out to the internet or in to
an intranet.
