The Microsoft® Exchange Server Analyzer Tool reads the following registry entry to determine the setting on the SecondsPerDSNPass registry value:
If the Exchange Server Analyzer finds that the SecondsPerDSNPass key is present and not set to 10, the Exchange Server Analyzer displays a non-default configuration message.
This setting is used to optimize Delivery Status Notifications (DSNs) and specifies the number of seconds for each DSN processing pass. As soon as this threshold has been surpassed, DSN generation will be stopped and then restarted later. It is recommended that the default values be modified only after serious consideration. This specific setting should only be modified after consulting with Microsoft Support Services. The defaults were carefully selected for optimal performance in most environments. A general best practice is to address the root cause of the problem instead of modifying the queuing behavior on the Exchange server.
The Exchange Server Analyzer reports this configuration for informational purposes only. No action is required.
