I just started sending mail out through our IronPort. The top user in the Top Users report is "No User Information". What might those be?

Could you please run the version command in your box and post the results.

Could be the report level for your appliance or you need to wait until the data became available (5-15 mins) or a report corruption due to some improper reboot.

In any case, I would recommend you to open a support ticket using the suport request.

Based on the version output, I would not expect the report level to be limited.

If you continue to be not able to see the reports, please submit a support request.

Also keep in mind that "No User Information" can refer to messages that have been relayed through the IronPort appliance without an Envelope-From address. For instance, a sender such as "<>".

These are typically bounce messages. This is not a defect or a critical issue. It is just the way the sending host is configured to send bounces.

The IronPort has no control over this setting. Generally, the sending host will add a "[email protected]" or "[email protected]" type address as the From message header for such bounce messages.
