I've built some really nice dashboards, using feedback form the North American FML ATP team members, that I think you'll all really enjoy. I've shared it with a few customers that were under attack and they found it to be extremely helpful. I would suggest creating a FortiMail dashboard with 9 tabs. Then just load each XML file into each own's tab.
Please let me know what you think of it.
Note- I'll be uploading a series of other dashboards for other Fortinet products too.
