Delivery
The delivery phase of the Email Pipeline focuses on the final phase of email 
processing, including limiting connections, bounces, and recipients.
Virtual gateways
The Cisco IronPort Virtual Gateway technology enables users to separate the 
Cisco IronPort appliance into multiple Virtual Gateway addresses from which to 
send and receive email. Each Virtual Gateway address is given a distinct IP 
address, hostname and domain, and email delivery queue.
For more information, see “Using Virtual Gateway™ Technology” in the 
“Configuring Routing and Delivery Features” chapter of the Cisco IronPort 
AsyncOS for Email Advanced Configuration Guide
.
Delivery Limits
Use the 
deliveryconfig
 command to set limits on delivery, based on which IP 
interface to use when delivering and the maximum number of concurrent 
connections the appliance makes for outbound message delivery. 
For more information, see “Set Email Delivery Parameters” in the “Configuring 
Routing and Delivery Features” chapter of the Cisco IronPort AsyncOS for Email 
Advanced Configuration Guide
.
Domain-Based Limits
For each domain, you can assign a maximum number of connections and 
recipients that will never be exceeded by the system in a given time period. This 
“good neighbor” table is defined through the Mail Policies > Destination Controls 
page (or the 
destconfig
 command).
For more information, see “Controlling Email Delivery” in the “Configuring 
Routing and Delivery Features” chapter in the Cisco IronPort AsyncOS for Email 
Advanced Configuration Guide.
