Cisco Cisco Email Security Appliance C190 Guia Do Utilizador

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 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.
