Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

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.” 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.
