Viewing mail statistics

The FortiView > Mail Statistics > By Count tab contains summaries of the number of email messages in each time period that the FortiMail unit detected viruses, spam, or neither.

The FortiView > Mail Statistics > By Size tab contains summaries by the file sizes of email messages in each time period that the FortiMail unit detected viruses, spam, or neither.

Mail statistics may also be viewed by scan speed and by transfer speed.

For email messages classified as spam, mail statistics include which FortiMail feature classified the email as spam, such as Bayesian antispam databases, access control rules, the system-wide block list, or email user-configured block lists.

For email not classified as spam by any antispam scan, mail statistics label it as Not Spam.

In addition to viewing overall trends via the graph, you can also view details at each point in time. To view these details, hover your mouse over a bar in the graph. A tool tip appears next to that point on the graph, including the name of the antispam category, message count, and percentage relative to the overall mail volume at that time.

The FortiMail unit can also generate reports on the total number of active mailboxes during a particular time period, as specified in the report profile creation under Log & Report > Report Setting > Mailbox Statistics. For more information, see Configuring mailbox statistics.

To use the Mail Statistics tab, first configure your FortiMail unit to detect spam and/or viruses. For more information, see Configuring profiles and Configuring policies.

Microsoft 365 notification statistics

For FortiMail units that are subscribed to a Microsoft 365 account, mail statistics may also be viewed by notification delay and by notifications received by FortiMail, to aid in troubleshooting and other purposes. These tabs are only available from the Microsoft 365 view, under FortiView > Mail Statistics > Notification Delay and FortiView > Mail Statistics > Received Notification respectively.

The Notification Delay tab contains summaries of the amount of time notifications were delayed. This is determined by the time when the email arrives in the MS365 mailbox and the time when the FortiMail unit receives the notification. Notification delay can be viewed by varying time periods, including by minute, hour, day, month, and year.

The Received Notification tab contains summaries of the number of notifications received by FortiMail. Received notifications can be viewed by varying time periods, including by minute, hour, day, month, and year.
