A notification mechanism that aggregates multiple email tracking status updates into a new type of aggregated message, and transports this new type of message according to a configured interval. The tracking status transported in this aggregated status message can be a positive delivery event, a negative delivery event, hand-off of ownership, or any information to be communicated. This information can be delivered to email users to provide information about the message delivery and, routed to messaging system applications such as journaling (to allow rich delivery information in a journal report) and/or high-availability transport (to allow resubmission of a message in case of hardware failure).
