Viewing mail statistics
Your FortiMail unit can show data about the number of email in each time period that the FortiMail unit detected with viruses, spam, or neither. It can also track the file sizes of email, scan speed, and transfer speed.
For email messages classified as spam, mail statistics include which FortiMail feature classified the email as spam, such as access control rules, the system-wide block list, or per-user block lists.
For email that is 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.
To view mail statistics
-
If you want to view statistics about mailboxes or domain-level mail statistics, purchase the feature license and enable the feature. See Mailbox accounting service and Domain mail statistics.
By default, their corresponding areas of the GUI are hidden and disabled.
-
Configure your FortiMail unit to detect spam and/or viruses. See Configuring profiles and Configuring policies.
-
Go to:
- FortiView > Mail Statistics > By Count
- FortiView > Mail Statistics > By Size
- FortiView > Mail Statistics > By Scan Speed
- FortiView > Mail Statistics > By Transfer Speed
- FortiView > Mail Statistics > Active Mailbox
Alternatively, instead of using the graph in FortiView, you can generate reports on the total number of active mailboxes during a particular time period. For details, see Configuring mailbox statistics.
Microsoft 365 and Google Workspace notification statistics
For FortiMail units that are subscribed to a Microsoft 365 or Google Workspace 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 &Google Workspace view, under FortiView > Mail Statistics > Notification Delay and FortiView > Mail Statistics > Received Notification.
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 Microsoft 365 or Google Workspace 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.
