About Creating Classification Rules for Bounce Messages

You can extend the Bounce Handler Daemon's ability to recognize different categories and types of bounces by creating rules that specify how values in the delivery status notification messages received for undelivered emails are to be classified. You create new bounce classification rules in the following files, which are located in the bhd_install_home/config directory:

• customDCBounceConfig. Used to define rules for classifying bounce messages by matching specified string values in the Diagnostic Code entry of the delivery status notification message
• customFromBounceConfig. Used to define rules for classifying bounce messages by matching specified string values in the From header of the delivery status notification message
• customSubjectBounceConfig. Used to define rules for classifying bounce messages by matching specified string values in the Subject header of the delivery status notification message

You can create as many bounce message classification rules as required for your Siebel Marketing environment. If you create custom classification rules, then bounce messages are classified using these custom rules. If you choose not to create custom classification rules, or if the Email Marketing Server cannot find a match for an undelivered email in the custom classification rules you create, then bounce messages are classified using standard Siebel Marketing functionality.

Note that you cannot customize the following Bounce Handler Daemon processing functionality:

• If the delivery status notification message for an undelivered email contains a Diagnostic Code entry, then entries in the customFromBounceConfig and customSubjectBounceConfig files are not processed.

  If the delivery status notification message does not contain a Diagnostic Code entry, then entries in the customFromBounceConfig file take precedence over entries in the customSubjectBounceConfig file.

• If the delivery status notification message for an undelivered email contains a From header which includes a value equal to MAILER-DAEMON, then entries in the customFromBounceConfig and customSubjectBounceConfig files are not processed.
• If the delivery status notification message for an undelivered email contains an Action field which includes a value equal to Failed, then entries in the customFromBounceConfig and customSubjectBounceConfig files are not processed.
