Delivery
The act of delivering email messages to recipient domains or internal mail hosts
from the IronPort appliance from a specific IP interface. The IronPort appliance
can deliver messages from multiple IP interfaces within same physical machine
using Virtual Gateway technology. Each Virtual Gateway contains a distinct IP
address, hostname and domain, and email queue, and you can configure different
mail flow policies and scanning strategies for each.

You can tailor the configuration of the delivery that the IronPort appliance
performs, including the maximum simultaneous connections to remote hosts, the
per-Virtual Gateway limit of maximum simultaneous connections to the host,
and whether the conversations to remote hosts are encrypted.
