Product Overview
Email remains one of the most frequently used business communication channels and one of the most attractive routes for phishing, credential theft, malicious attachments, impersonation and accidental data exposure. A secure email platform therefore needs to do more than block obvious spam. It must inspect sender identity, message structure, links, attachments and policy conditions while remaining manageable for security and messaging teams. FortiMail is Fortinet’s dedicated email security family, and VM04 is the four-vCPU virtual appliance edition intended for organizations that want control over how the platform is hosted and integrated.
The virtual format is particularly useful for businesses that already operate VMware, Hyper-V, KVM, Citrix XenServer or supported cloud infrastructure and prefer to deploy security services as software rather than add a separate rack appliance. Fortinet also lists AWS, Microsoft Azure, Google Cloud Platform, Oracle Cloud Infrastructure and Nutanix AHV among supported environments for the virtual line. This provides architectural choice, but every platform still requires proper resource reservation, network design and licensing.
FortiMail can operate in several modes. Gateway mode places the system in the mail flow and uses MTA services to inspect and relay inbound and outbound messages. Transparent mode can reduce changes to the existing email-server network design. Server mode enables FortiMail to function as a messaging server with SMTP, POP3, IMAP and webmail functions. Optional Microsoft and Google cloud email API integration can support out-of-line inspection and post-delivery actions when the relevant services are licensed. This flexibility is valuable because different organizations have different constraints around DNS, mail routing, cloud tenancy and change windows.
For Dubai and UAE buyers, a sensible procurement process starts with the operational requirement. A security team may want stronger business email compromise controls, URL protection and sandbox integration; a messaging team may focus on mail flow, quarantine, domains and availability; procurement may need a clear bundle and renewal path. FourTeck.com can help combine these inputs into a more accurate product request so the chosen FortiMail model, support term and security services match the intended deployment rather than being selected on model name alone.
Key Business Benefits
◆ Layered Email Protection
FortiMail combines sender reputation, protocol checks, authentication methods, content analysis, antispam and malware controls. For buyers, layered inspection matters because modern email threats do not all look the same. A suspicious sender, spoofed domain, harmful attachment and malicious link may require different detection methods, so relying on a single inspection technique creates avoidable gaps.
◆ Virtual Deployment Flexibility
The VM04 can run on supported private virtualization and public-cloud platforms, allowing security teams to place email protection within established infrastructure standards. This can simplify rack planning and make the deployment align with virtualization, cloud governance and disaster-recovery practices already used by the organization.
◆ Enterprise Capacity Headroom
Fortinet positions VM04 for mid-to-large enterprise scenarios and supports up to four vCPUs, 16 GB memory and 4 TB virtual storage. That does not mean every deployment requires the maximum allocation, but it gives buyers a defined resource envelope when planning current mail volume, quarantine, logging and future growth.
◆ Identity and Spoofing Controls
Support for SPF, DKIM and DMARC, along with impersonation and cousin-domain detection capabilities in applicable bundles, helps security teams address common sender-trust problems. The business value is reduced exposure to fraudulent emails that imitate executives, suppliers or trusted domains.
◆ Data Protection and Encryption
FortiMail includes data-loss-prevention capabilities and supports secure message delivery methods such as TLS, S/MIME and identity-based encryption features. This is useful where email carries financial, customer, operational or other sensitive information and policy enforcement must extend beyond inbound threat blocking.
◆ Management Visibility
Real-time dashboards, reporting, message tracking, quarantine controls, logging, SNMP, Syslog and REST API support help teams understand what is happening to email traffic. Better visibility can shorten troubleshooting and make policy review easier when users report missing, delayed or suspicious messages.
The practical advantage of these benefits is that one platform can cover prevention, policy control, user quarantine, reporting and integration requirements while still fitting into a virtual infrastructure model. Buyers should remember that specific advanced functions depend on the FortiGuard and support bundle selected. The purchase conversation should therefore include both the VM entitlement and the required security services.
Product Highlights
VM04 is licensed and sized as the four-vCPU tier in the FortiMail virtual appliance family.
Fortinet specifies 4–16 GB memory and 250 GB–4 TB virtual storage for this model.
The published platform limit supports larger multi-domain business environments, subject to configuration and licensing considerations.
Gateway, transparent and server deployments allow different integration strategies.
Microsoft and Google mailbox integration can be licensed for supported real-time, scheduled and post-delivery workflows.
FortiMail supports HA scenarios including active-passive and configuration-synchronization approaches.
Fortinet publishes indicative performance figures for VM04 based on 100 KB messages and a specified test platform. Those results are useful for model comparison, but they should not be treated as guaranteed production throughput. Real performance changes with host CPU capability, storage, message size, enabled inspection services, traffic mix, policy complexity and deployment design. FourTeck.com recommends using peak mail-flow data rather than mailbox count alone when validating the model.

When choosing a configuration, start with the busiest expected mail period rather than an average day. A company may process a moderate daily volume but still experience large spikes during marketing campaigns, automated system alerts or business-hour peaks. Security functions also influence resource use. Advanced threat inspection, content disarm, sandbox workflows, URL analysis, DLP rules and detailed reporting can add processing compared with simple routing.
Storage planning deserves equal attention. The published 250 GB minimum allows the virtual machine to be deployed, but organizations that retain extensive quarantine, reporting data or archives may require more. If the organization expects large message retention or email archiving, discuss those requirements separately rather than assuming the minimum storage allocation is sufficient. The same principle applies to memory: four gigabytes is the minimum for VM04, while up to sixteen gigabytes is supported. Resource allocation should reflect production demand and hypervisor design.
Configuration and Buyer Guidance
A successful email-security purchase starts with a short discovery exercise. FortiMail is not a simple appliance that should be chosen only by the number printed in the model name. The VM tier, subscription bundle, deployment mode and operational design all affect the final solution. Before requesting a quotation, procurement and IT teams should gather the information below.
Mail Flow
Measure normal and peak messages per hour, average message size, inbound versus outbound traffic and any known seasonal spikes.
Domains and Users
List protected domains, aliases, mailbox environment and any multi-tenant or delegated-administration requirements.
Infrastructure
Confirm the hypervisor or cloud platform, available CPU, memory, storage, network interfaces and disaster-recovery arrangement.
Security Functions
Define whether the project needs advanced threat protection, cloud sandboxing, content disarm, DLP, encryption, URL click protection or API integration.
Mail Architecture
Identify the current platform, DNS and MX design, mail-relay path, LDAP or directory integration and whether an inline or API-based model is preferred.
Support and Renewal
Confirm the required contract length, FortiCare level, FortiGuard bundle and internal responsibility for upgrades, monitoring and policy maintenance.
Share these details with FourTeck.com before quotation. They help distinguish whether VM04 is correctly sized, whether a smaller or larger FortiMail VM should be considered, and which subscription options are necessary. This reduces the risk of receiving a quote that contains the right model but the wrong services, term or resource assumption.
Ideal Business Use Cases
Enterprise Secure Email Gateway
Organizations can deploy FortiMail in gateway mode in front of an existing mail system to inspect inbound and outbound SMTP traffic. This is relevant when the company wants a dedicated policy and security layer around an on-premises or hosted mail platform while retaining its existing mailbox infrastructure.
Microsoft 365 Security Layer
Businesses using Microsoft 365 can evaluate FortiMail as an additional email security layer. Depending on the design and licensed bundle, deployment can use mail-flow integration or optional API capabilities. Buyers should decide whether they want inline inspection, post-delivery remediation, internal-mail visibility or a combination.
Google Workspace Protection
Google Workspace environments can also be considered for supported FortiMail integration. The appropriate approach depends on the organization’s mail routing, API requirements, directory structure and security objectives, so the cloud-mail architecture should be documented before the license is selected.
Multi-Domain Corporate Groups
The published capacity of up to 500 protected email domains makes VM04 relevant to organizations that manage many brands, subsidiaries or business domains. Per-domain policy and administrative requirements should still be mapped carefully so the operational model remains manageable.
Security-Focused Virtual Data Centers
Companies standardizing infrastructure on virtual machines may prefer VM04 because it can be placed within existing compute, backup and disaster-recovery frameworks. Host resource guarantees, storage performance and network design need to be included in the deployment plan.
Regulated or Policy-Driven Email
Organizations that need DLP, encryption, message tracking, audit reporting and structured policy control can use FortiMail capabilities to strengthen governance around email. The specific rule set should be based on the organization’s compliance and data-handling obligations rather than generic settings.
VM04 can also fit hybrid environments where some mail services remain on-premises while others move to cloud platforms. The virtual form factor makes it easier to place the security layer near the required workload, but hybrid mail routing can become complex. Buyers should document domains, connectors, public DNS, certificates, trusted relays, outbound routing and failover paths before implementation. This planning improves both security and operational continuity.
FortiMail VM04 Email Threat Protection
The first major reason to deploy a dedicated email security platform is threat reduction. FortiMail uses multiple inspection layers rather than one static filter. Sender and domain reputation can help identify known bad sources, while connection and protocol checks can reject or challenge suspicious behavior earlier in the mail flow. SPF, DKIM and DMARC support provides important domain-authentication context, and message content can be evaluated using signatures, heuristics, URL reputation, attachment analysis and other controls.
For business email compromise, technical controls need to look beyond traditional malware. Many fraudulent messages contain no malicious executable at all; instead they imitate an executive, supplier or trusted business partner and ask for a payment, bank-account change or credential reset. FortiMail supports impersonation analysis, anti-spoofing and cousin-domain detection within applicable feature bundles, helping teams apply additional scrutiny to these social-engineering patterns.
Advanced threat protection options can add content disarm and reconstruction, URL click protection and cloud sandboxing. These functions matter when files or links are not clearly known as malicious at the moment they first arrive. Content disarm can remove active elements from supported documents, URL protection can reassess links when a user clicks, and sandbox analysis can provide another inspection layer for suspicious files. Buyers should verify which of these features are included in the selected FortiGuard bundle because the virtual appliance entitlement and the subscription services are separate parts of the commercial decision.
FortiMail VM04 Deployment and Scalability
VM04 is designed for organizations that want the operational control of a self-managed FortiMail deployment while avoiding a dedicated physical chassis. That flexibility is useful only when the host environment is sized correctly. Fortinet specifies a maximum of four vCPUs for this edition, four to sixteen gigabytes of virtual memory, one to six virtual NICs and 250 GB to 4 TB of storage. Those ranges let administrators scale resources within the licensed model as the workload changes, but scaling is not unlimited; the VM08 or higher tier may be more appropriate when projected demand exceeds the VM04 envelope.
Supported infrastructure options include widely used hypervisors and public-cloud environments. This gives architects a choice between an on-premises virtual cluster, private cloud or hosted cloud model. The best placement depends on mail-system location, latency, security architecture, available compute and resilience requirements. A business using Microsoft 365 may choose a different topology from a company running Exchange on-premises, and a hybrid tenant may need multiple connectors and careful routing rules.
High availability should be discussed early. FortiMail supports HA capabilities including active-passive operation and configuration synchronization. In a virtual environment, platform-level VM availability does not automatically replace application-level design. Buyers should consider how mail queues, quarantine, virtual IPs, network paths and upstream DNS behave during a host or instance failure. Resilience also affects resource cost because a second instance or additional cloud capacity may be required.
Capacity planning should use realistic data. Fortinet publishes indicative VM04 rates of 306,000 messages per hour for routing, 279,000 for FortiGuard antispam plus virus outbreak processing and 225,000 for Enterprise ATP under stated test conditions. These figures show relative model capability, not guaranteed production rates. Measure peak traffic and average message size, then add growth and security-service overhead before finalizing the design.
FortiMail VM04 Management, Policy and Data Protection
Email security becomes difficult when administrators cannot explain why a message was blocked, where it was quarantined or which policy caused an action. FortiMail addresses that operational need with dashboards, activity and incident logging, built-in reporting, detailed message tracking and quarantine controls. These tools help messaging and security teams investigate user reports, verify policy behavior and review suspicious trends without relying only on raw SMTP logs.
Policy flexibility is also important for organizations with multiple departments or domains. VM04 supports hundreds of protected domains and published recipient-policy limits that allow different rules to be applied across the environment. Per-domain administration and multi-tier administration can be useful where responsibilities are delegated, although large multi-tenant or service-provider designs should confirm advanced management requirements and license implications before purchase.
Data protection extends the platform beyond inbound threat filtering. FortiMail supports data-loss-prevention functions, file fingerprinting and sensitive-data detection, along with encryption options such as TLS, S/MIME and identity-based encryption. These controls can help organizations reduce accidental disclosure and create more consistent handling for sensitive messages. DLP policies must still be designed carefully: overly broad rules can create false positives, while weak patterns may miss important content.
Integration options help connect FortiMail with the broader security and operations environment. Fortinet lists integrations with tools such as FortiAnalyzer, FortiSandbox, FortiSOAR and other Fortinet components, while REST API, Syslog and SNMP support can assist with monitoring and automation. Buyers should decide which integrations are operationally required and whether separate licenses or infrastructure are needed. This avoids assuming that every integration is included automatically with the base VM entitlement.
Questions Business Buyers Ask Before Choosing This Virtual Email Platform
The questions below focus on practical fit, sizing, licensing and deployment. They are useful when technical teams and procurement teams need to decide whether the four-vCPU FortiMail tier matches the current requirement or whether another model should be quoted.
Is VM04 appropriate for a mid-sized company that is growing quickly?
It can be a strong fit when current and projected mail traffic, domain count and security features stay within the model’s resource and performance envelope. Fortinet positions VM04 for mid-to-large enterprise deployments. A growing company should compare peak messages per hour, expected storage, protected domains and future user growth before deciding that VM04 provides enough headroom.
How much virtual CPU, memory and storage should we assign?
The model supports up to four vCPUs, with Fortinet specifying 4–16 GB memory and 250 GB–4 TB storage. The correct allocation depends on mail volume, quarantine, logging, security services and retention needs. Do not assume the minimum allocation is ideal for production simply because the VM can start with it.
Can we deploy it with Microsoft 365 without changing MX records?
FortiMail supports optional Microsoft cloud email API integration that can operate out of line and does not require an MX-record change for that API workflow. Whether this is the right design depends on the selected bundle and the desired inspection path. Some organizations still prefer gateway routing, so the mail architecture should be reviewed before quotation.
What should we check when replacing an older FortiMail appliance?
Compare more than raw throughput. Review protected domains, current policies, certificates, mail routes, quarantine size, logs, archives, directory integrations, DNS records, HA design and the security services in use. Migration from hardware to VM also requires mapping old interface behavior to virtual NICs and confirming that the host platform has sufficient reserved resources.
Does the base virtual appliance include every advanced protection feature?
No assumption should be made that every advanced feature is included in every commercial bundle. Fortinet offers different FortiGuard and support combinations. Functions such as cloud sandboxing, content disarm, URL click protection and cloud-email API capabilities depend on the selected service package. Ask for the quote to name the exact bundle and contract term.
How should we judge the published messages-per-hour figures?
Treat them as sizing references, not guaranteed production throughput. Fortinet’s VM figures use specific hardware and 100 KB test messages, while real environments differ in CPU speed, storage, message size, traffic bursts and inspection depth. Use your own peak traffic data and leave margin for growth, failover and additional security services.
Can the platform protect many separate business domains?
Fortinet publishes a limit of 500 protected email domains for VM04. This makes the model relevant to corporate groups and multi-domain environments, but domain count alone does not determine suitability. Policy volume, administrative separation, mail traffic and multi-tenancy requirements may influence whether additional management capabilities or a larger model are appropriate.
Which information helps FourTeck prepare a more accurate quote?
Provide the mail platform, protected domains, approximate mailbox count, peak messages per hour, average message size, preferred hypervisor or cloud, required security features, HA requirement and desired contract term. Also state whether you need Microsoft or Google API integration. These details help align the VM license and subscriptions with the actual project.
When should we consider VM08 instead of VM04?
Consider the next tier when projected workload, domain requirements, resource needs or growth margin approach the VM04 limits. VM08 supports more vCPU, memory and storage capacity. A model upgrade may also be prudent when high availability or rapid growth means a four-vCPU node would operate too close to its comfortable production ceiling.
Business Requirements to Match Before You Buy
For businesses that need stronger phishing defenses
Evaluate the subscription bundle for impersonation analysis, URL protection, sandboxing and content-disarm capabilities, not just basic antispam. The correct license combination should match the organization’s actual threat model.
For a virtual-first data center
VM04 is suitable when the supported hypervisor or cloud environment can provide dedicated compute, memory, storage and networking. Confirm resource reservation and backup strategy before deployment.
For multiple business domains
The published domain capacity is substantial, but buyers should also map policy count, delegated administration and traffic per domain so that operational complexity does not become the limiting factor.
For Microsoft 365 or Google environments
Decide whether the requirement calls for gateway mail-flow protection, optional API integration or both. Licensing and implementation differ, so the desired architecture should be explicit in the quote request.
For organizations planning rapid growth
Use projected traffic and domain counts rather than current usage alone. If the expected growth would push the four-vCPU tier close to its practical limit, compare VM08 before purchase.
For teams requiring detailed audit visibility
FortiMail provides reporting, message tracking and logging functions. Define retention and external logging needs because they can influence storage and integration design.
These requirement-led checks help turn a product inquiry into a deployable solution. The same VM can behave very differently depending on how mail is routed, which inspection services are enabled, how much data is retained and how the organization handles failover. Procurement teams should therefore request a configuration description alongside the commercial quotation.
What Buyers Should Check Before Purchase
Before ordering, buyers should verify the entire email-security requirement rather than treating FML-VM04 as a standalone software SKU. The license tier determines the virtual CPU ceiling, while FortiGuard services determine much of the advanced security functionality. The host platform, storage and network design determine how well the virtual appliance can use its licensed capacity. All three areas need to be aligned.
Configuration Fit
Confirm vCPU, memory, storage, NICs, peak mail flow and protected domains. If requirements are close to platform limits, compare the next model rather than leaving no growth margin.
Compatibility Check
Validate the current hypervisor or cloud release against Fortinet support documentation and confirm mail-platform, DNS, LDAP, certificate and network requirements.
License and Renewal
Ask for the exact FortiCare and FortiGuard bundle name, contract duration and renewal scope. Advanced protection services should be explicitly listed.
Quote Preparation
Provide the deployment platform, mail domain count, mailbox platform, expected throughput, desired security features, HA design and project location.
Buyers replacing another secure email gateway should also review migration effort. Existing allowlists, blocklists, DLP dictionaries, routing rules, certificates, quarantine data and message journals may need to be recreated or migrated. The cutover plan should include DNS TTL changes, mail queue handling, rollback steps and user communication. If transparent mode or API integration is being considered to reduce mail-flow changes, validate that the chosen approach still meets all required inspection and remediation objectives.
Long-term cost should include more than the initial VM entitlement. Subscription renewals, cloud or virtualization compute, storage growth, backup, support and administrative time all contribute to total ownership. The best configuration is therefore the one that provides sufficient security and capacity without buying unused scale. FourTeck.com can help review these practical points before the quotation is finalized.
UAE Availability and Service Support
FourTeck.com supports Fortinet product inquiries for organizations in Dubai and across the UAE. For FortiMail virtual appliances, availability is influenced by the exact VM SKU, FortiGuard subscription bundle, FortiCare support term, order quantity and supplier status. Because software and security subscriptions are commonly quoted with specific service periods, buyers should avoid relying on an old part number or previously purchased bundle without checking the current ordering structure.
Quote support can include model selection, virtual resource review, license term clarification, deployment-mode discussion and identification of related subscriptions. FourTeck.com can also help procurement teams structure a request that separates the base VM entitlement from recurring security services so finance teams have a clearer view of initial and renewal requirements.
Delivery coordination for a virtual product normally focuses on license fulfillment and any associated support or subscription documentation rather than shipping a physical appliance. Exact fulfillment method and timing can vary. Buyers should confirm the end-customer details, intended region, required contract start date and support registration requirements at the time of order.
Dubai, Abu Dhabi, Sharjah and Ajman Coverage
Businesses in Dubai, Abu Dhabi, Sharjah, Ajman and other UAE locations can contact FourTeck.com for Fortinet email-security product inquiries, configuration review and quotation assistance. For distributed organizations, it is helpful to state whether the project covers one central mail environment or several business entities, domains or sites. The team can then help align the requested FortiMail model and subscription term with the broader rollout requirement. Availability and commercial terms can vary by order, so final confirmation should be based on the exact SKU and license package requested.
Regional GCC and Africa Availability
FourTeck.com also supports business technology inquiries across selected GCC and Africa markets through regional inquiry channels. Organizations with operations in Saudi Arabia, Qatar, Oman, Kuwait, Bahrain, Kenya, Uganda or other supported markets can request guidance for Fortinet product sourcing and regional project requirements. Software licensing, support registration, tax treatment, delivery method and commercial availability may differ by country.
Regional procurement teams should identify the end-user country, deployment location and contracting entity before the quotation is prepared. This is especially important for cybersecurity subscriptions because service eligibility, support terms and registration details may depend on the destination and purchase route. For multi-country projects, it is often more efficient to provide a single schedule listing each location, required quantity, contract term and deployment platform.
Regional FourTeck resources include FourTeck Kenya, FourTeck Uganda, FourTeck Africa and FourTeck Kuwait. Contact the appropriate regional channel for country-specific guidance.
Other FortiMail Virtual Options Buyers May Consider
The best FortiMail virtual model depends on workload and growth, not only company size. Smaller editions can be suitable where traffic is modest, while larger editions provide additional vCPU, memory, storage and protected-domain capacity. Consider these related models when preparing a sizing comparison.
FortiMail VM02
Suitable for smaller to midsized organizations that do not require the four-vCPU tier. Compare traffic, protected domains and future growth before choosing the lower model.
FortiMail VM08
A larger virtual appliance tier for enterprise environments that need more compute and capacity headroom than VM04 can provide.
FortiMail VM16
Designed for larger enterprise deployments where higher processing scale, memory and storage ranges are required.
FortiMail VM32
The highest vCPU tier in the listed FortiMail VM family and intended for the largest virtual email-security workloads.
A related-model comparison is particularly useful when a deployment is near a sizing boundary. Buying the smallest model that works under average traffic can leave little room for message spikes, added inspection services or business growth. At the same time, moving several tiers higher without evidence can increase licensing cost unnecessarily. Share peak mail-flow measurements and growth forecasts with FourTeck.com to make the comparison more meaningful.

Frequently Asked Questions
What is FortiMail VM04 used for?
It is a virtual email security appliance used to inspect and control inbound and outbound business email. Organizations can use it for antispam, malware protection, sender-authentication checks, business email compromise defenses, data-loss-prevention policies, quarantine, reporting and other email-security functions. Exact capabilities depend on the FortiGuard subscription bundle and deployment mode selected.
How many vCPUs does the VM04 model support?
Fortinet specifies a maximum of four virtual CPUs for this model. The virtual appliance also supports a published memory range of 4 GB to 16 GB and a virtual storage range of 250 GB to 4 TB. Production sizing should consider mail volume, host performance and enabled security services rather than assigning resources arbitrarily.
Is FortiMail VM04 suitable for Microsoft 365?
Yes, FortiMail can be used with Microsoft 365, and Fortinet offers optional cloud email API integration in addition to traditional mail-flow approaches. The correct design depends on whether the organization wants inline gateway protection, out-of-line API inspection, post-delivery actions or a combined approach. Confirm the required bundle and tenant architecture before purchase.
Can it run in public cloud environments?
Fortinet lists major cloud platforms such as AWS, Microsoft Azure, Google Cloud Platform and Oracle Cloud Infrastructure among the supported environments for FortiMail virtual appliances. Cloud deployment still requires appropriate compute, storage, networking and licensing. Verify the current platform-specific deployment documentation for the target cloud before implementation.
Does the model support high availability?
FortiMail supports high-availability deployment scenarios including active-passive operation and configuration synchronization. The exact design should account for virtual networking, host placement, mail queues, DNS, upstream routing and failure behavior. Organizations should decide whether application-level HA, hypervisor-level resilience or both are required for the business continuity objective.
How many protected domains can VM04 handle?
Fortinet publishes a protected email domain limit of 500 for VM04. Domain capacity is only one sizing factor. Large numbers of policies, heavy traffic, complex inspection, delegated administration or multi-tenant requirements can change the practical design. A sizing review should include domain count together with message throughput and resource requirements.
Is every FortiGuard service included automatically?
No. Fortinet offers multiple feature and support bundles, and advanced capabilities can depend on the selected subscription. Buyers should ask the quotation to state the exact bundle, service term and included functions. This is important for features such as cloud sandboxing, content disarm, URL click protection and cloud-email API services.
How can I request a quotation in the UAE?
Contact FourTeck.com with the required model, deployment platform, domain count, approximate mailbox environment, peak email traffic, preferred security bundle, support period and project location. If the exact bundle is not known, describe the security functions you need. FourTeck.com can use that information to help prepare a more relevant quotation.
Should we choose VM04 or a larger FortiMail VM?
Choose based on measured and projected workload. If peak mail volume, resource demand or domain growth would place the four-vCPU model near its limits, compare VM08 or higher. If the environment is considerably smaller, VM02 may be more economical. A sizing review should leave sensible headroom without buying unnecessary capacity.
