Cisco Cisco Email Security Appliance C160 Mode D'Emploi

concurrency (the default per listener is 600 connections for private listeners and 1000 connections for 
public listeners). Setting the value lower than the default prevents the Cisco IronPort gateway from 
dominating weaker networks. For example, certain firewalls do not support large numbers of 
connections, and the Cisco IronPort could induce Denial of Service (DoS) warnings in these 
environments. 

In the following example, the 

deliveryconfig

 command is used to set the default interface to “Auto” 

with “Possible Delivery” enabled. The system-wide maximum outbound message delivery is set to 9000 
connections. 

Our Email Gateway configuration now looks like this:

mail3.example.com> deliveryconfig

Choose the operation you want to perform:

- SETUP - Configure mail delivery.
