Hello,
I am trying to create a custom DSN to send a NDR alerting the internal sender that his/her mail has been rejected due to profanity. I created a DSN 5.2.9 with the message "Your message appears to contain profanity or unprofessional language - please correct before re-sending" However, when i try to apply the DSN to the rule I get "The value that you entered cannot be saved because it contains the character "5". To save this, you must first configure a custom delivery status notification.
What am I missing that would cause the server not to recognize that there is a custom DSN? Note that from powershell, the server returns the correct message when I enter Get-SystemMessage.
