FORTINET FML-VM08 FortiMail-VM 8-vCPU Software License

Choose the VM08 email-security scale

FML-VM08 is the eight-vCPU FortiMail virtual-appliance software order listed by Fortinet. The exact order row names VMware ESX/ESXi, Microsoft Hyper-V, Citrix XenServer and KVM. It does not describe a FortiGate firewall, an eight-port appliance or a physical server supplied with memory and disks.

Count domains separately from Server Mode mailboxes

The manufacturer's VM08 profile allows 1,000 protected email domains and 2,000 local mailboxes in Server Mode. These are different dimensions: a protected-domain limit is not an endpoint-agent count, and a local-mailbox figure is not the number of users automatically covered by a cloud subscription. Choose the intended mail deployment mode before estimating capacity.

Fortinet defines protected domains as domains configured on the appliance. Domain Associations can cover additional domains that share the primary domain's configuration. For a multi-domain deployment, inventory the separately configured domains and associated aliases rather than adding every alias to the same sizing measure. An advanced management license can increase the published protected-domain limit by 50%; that add-on is a separate order, not an automatic VM08 inclusion.

Plan CPU, memory and mail storage

The current VM08 data-sheet column lists up to eight virtual CPUs, one to six virtual NICs and a memory range of 4 GB to 64 GB. Those values describe the virtual appliance's resource envelope. This license does not ship physical network interfaces or guarantee that 16 GB of RAM is included.

The storage table specifies a 250 GB initial allocation and an 8 TB maximum for VM08. Its footnote explains that 250 GB is needed to install the default Fortinet OVF image; after deployment, that default image may be deleted and disk space reduced to no less than 50 GB. Plan the usable mail and quarantine storage for the actual retention policy. The published ceiling is not a disk supplied by this purchase.

Evaluate recipient-policy and profile limits

VM08 supports 800 recipient-based policies per domain and 3,000 per system for incoming or outgoing policy. The same data-sheet column gives 50 antispam, antivirus, authentication and content profiles per domain and 400 per system. Review the number of distinct policies and profiles across the organization's domains; a domain count alone does not describe that configuration complexity.

Separate VM licensing, hosted mail and service contracts

The ordering guide lists the VM08 platform separately from FortiMail Cloud hosted options and S-series VM subscription options. A hosted mailbox band is not this eight-vCPU VM license. The VM profile identifies DLP capability, while Microsoft 365 and Google email API integration is an add-on. Verify the exact quoted entitlement and software release before planning API-based protection.

FortiGuard antivirus, antispam and virus-outbreak services are identified under the Base Bundle in the guide; cloud sandbox is identified under Enterprise ATP. Confirm the applicable FortiCare and FortiGuard contract, its term, registration and activation route. Do not infer a one-, three- or five-year security bundle, perpetual support or a cloud account from the FML-VM08 name.

Validate the deployment mode on the selected hypervisor

The data sheet cautions that Transparent mode is not fully supported on Microsoft Hyper-V and cloud hypervisors because of network-configuration limitations. Match Gateway, Transparent or Server Mode to the installed platform and release. Published mail-processing benchmarks depend on hardware, message size and test conditions; they are not firewall, IPS or VPN throughput delivered by this license.

For a quotation, provide the exact VM08 code, hypervisor and release, allocated CPU, memory and disk resources, deployment mode, configured-domain count and any Server Mode mailbox requirement. Check registration rights, service coverage, add-ons and fulfillment with the seller. The image is an official Fortinet brand reference, not an appliance photograph or an activated-license certificate.

Frequently asked questions

Does VM08 include an eight-port firewall?

No. It is a FortiMail virtual-appliance order for eight vCPU cores. Its virtual NIC allowance is not a set of physical ports.

Are 1,000 domains and 2,000 mailboxes interchangeable limits?

No. Protected domains describe configured domains; the local-mailbox figure applies to Server Mode. Check the deployment mode and domain associations independently.

Is a Microsoft 365 API subscription included automatically?

The VM08 table labels cloud email API integration as an add-on. Confirm that separate entitlement on the quotation.
