Cisco Cisco Email Security Appliance C170 Betriebsanweisung

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.

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.

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.

Use the Network > SMTP Routes page (or the 

smtproutes

 command) to redirect all email for a particular 

domain to a specific mail exchange (MX) host, without rewriting the envelope recipient.

For more information, see “Routing Email for Local Domains” in the “Configuring Routing and 
Delivery Features” chapter of the Cisco IronPort AsyncOS for Email Advanced Configuration Guide.

Use Global Unsubscribe to ensure that specific recipients, recipient domains, or IP addresses never 
receive messages from the Cisco IronPort appliance. If Global Unsubscribe is enabled, the system will 
check all recipient addresses against a list of “globally unsubscribed” users, domains, email addresses, 
and IP Addresses. Matching emails are not sent.

For more information, see “Using Global Unsubscribe” in the “Configuring Routing and Delivery 
Features” chapter of the Cisco IronPort AsyncOS for Email Advanced Configuration Guide.
