You can identify a customized delivery status notification (DSN) message based on its syntax. The identity is the customized DSN message's GUID or a string that consists of the following values:

The syntax of the DSN message identity is <Locale>\<Internal or External>\<DSN code>.

For each DSN code, you can create more than one customized DSN message, which can target internal senders or external senders, and different locales. For example, the following table shows some of the possible configurations for the DSN code 5.1.2 and the corresponding DSN message identities.
