Cisco Cisco Email Security Appliance C160 Mode D'Emploi

Time in Queue Messages (delay notification messages) generated by the system also use the DSN 
format. Change the default parameters by using the Bounce Profiles page on the Network menu (or the 

bounceconfig

 command) to edit existing or create new bounce profiles and change the default values 

for:

The minimum interval between sending delay warning messages.

The maximum number of delay warning messages to send per recipient. 

Note that it is possible to receive both a delay warning and a hard bounce for the same message 
simultaneously, if you have set a very small durations for both the “Maximum Time in Queue” setting 
and the minimum interval setting for “Send Delay Warning Messages.” Cisco IronPort Systems 
recommends using the default values for these settings as a minimum if you choose to enable sending of 
delay warning messages.

Further, delay warning messages and bounce messages originated by the appliance may be delayed by 
as much as 15 minutes during processing.

In the following example, a bounce profile named 

bouncepr1

 is created using the Bounce Profiles page. 

In this profile, all hard bounced messages are sent to the alternate address 

bounce-mailbox@example.com

.

 

Delay warnings messages are enabled. One warning message will be 

sent per recipient, and the default value of 4 hours (14400 seconds) between warning messages is 
accepted.
