When HAT Delayed Rejection is configured, connections that would get dropped based on the HAT 
Sender Group and Mail Flow Policy configuration can still authenticate successfully and get the RELAY 
mail flow policy granted.

You can configure delayed rejection using the 

listenerconfig --> setup

 CLI command. This behavior 

is disabled by default.

The following table shows how to configure delayed rejection for HAT.

example.com> listenerconfig

Currently configured listeners:

1. listener1 (on main, 172.22.138.17) QMQP TCP Port 628 Private

2. listener2 (on main, 172.22.138.17) SMTP TCP Port 25 Private

Choose the operation you want to perform:

- NEW - Create a new listener.

- EDIT - Modify a listener.

- DELETE - Remove a listener.

- SETUP - Change global settings.

[]> setup

Enter the global limit for concurrent connections to be allowed across all listeners.

By default HAT rejected connections will be closed with a banner

message at the start of the SMTP conversation. Would you like to do the rejection at the 

message recipient level instead for more detailed logging of rejected mail?
