Customizing Non-Delivery Reports (NDRs)
The ADVANCED-->Bounce/NDR Messages page lets you modify the information in an NDR and 
select the default language to use in the message.
The Barracuda Spam Firewall sends NDRs to email recipients and senders when one of their messages 
is blocked. The NDR contains a brief explanation of why the Barracuda Spam Firewall blocked the 
message. Information that you may want to add to an NDR includes the contact information of the 
Barracuda system administrator so internal users know who to contact if they have questions about a 
blocked message.
Note: The Barracuda Spam Firewall only sends out Non-Delivery Reports if these notifications have 
been enabled on the BASIC-->Spam Scoring and BASIC-->Virus Checking pages.
The following table describes the settings on the ADVANCED-->Bounce/NDR Messages page.
The following table describes the supported macros you can use in NDRs.
Field Description
Select NDR Language
Default Language Select the language to use for the Non-Delivery Reports. The Barracuda Spam 
Firewall automatically translates the default NDR messages to the language 
you specify. 
To customize the information in an NDR, select Custom and enter your 
customized text in the Customized NDRs section.
Note: If you customize NDRs and then later switch back to a predefined 
language, you lose all customization and the Barracuda system reverts back to 
the default message for the specified language.
