Black Hole Listener for an Enterprise Gateway
In the following example, the 
listenerconfig
 command is used to create a black hole queueing listener 
named 
BlackHole_1
 on the Management interface. This Host Access Table (HAT) for the listener is then 
edited to accept connections from the following hosts:
yoursystem.example.com
10.1.2.29
badmail.tst
.tst
Note
The final entry, 
.tst
, configures the listener so that any host in the 
.tst 
domain can send email to the 
listener named 
BlackHole_1
.
