Comma separated list of DSN notifications 'NEVER' under no circumstances a DSN must be returned to the sender. If you use NEVER all other notifications will be ignored. 'SUCCESS' will notify you when your mail has arrived at its destination. 'FAILURE' will arrive if an error occurred during delivery. 'DELAY' will notify you if there is an unusual delay in delivery, but the actual delivery's outcome (success or failure) is not yet decided.
