The FortiMail 3000F handles 3.5 Million messages per hour of email routing and 2.1 Million messages per hour with enterprise advanced threat protection enabled, across 2,000 email domains and 3,000 server-mode mailboxes.
2.1 million ATP messages an hour, 2,000 domains, 3,000 mailboxes, 20 TB maximum. Carrier and large service-provider scale. At this volume the deployment mode decision — gateway, transparent or server — has more effect on the design than the model choice does, and it should be settled first.
