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 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.

You can edit any bounce profile by clicking its name in the Bounce Profiles listing. You can also edit the 
default bounce profile. In this example, the default profile is edited to increase the 

maximum number of 

seconds to wait before retrying unreachable hosts 

from 3600 (one hour) to 10800 (three 

hours): 

In the following example, a bounce profile named 

minimalist

 is created. In this profile, messages are 

not retried when they bounce (zero maximum retries), and the maximum time to wait before retrying is 
specified. Hard bounce messages are disabled, and soft bounce warnings are not sent.
