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 gateway from dominating weaker 
networks. For example, certain firewalls do not support large numbers of connections, and this 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.

[]> setup

Choose the default interface to deliver mail.
