MailXP Glossary of Terms

Automatic resource scaling for storage and processing.

• Ensures consistent performance even during peak usage
• Prevents downtime or throttling from unexpected load

Why it matters: Traditional servers fail when overloaded. MailXP dynamically adjusts capacity, keeping email flow uninterrupted.

The ability of emails to reach inboxes without being flagged as spam. MailXP ensures:

• IP reputation management
• SPF/DKIM/DMARC validation
• Protection against blacklisting

Why it matters: Self-hosted mail often struggles with delivery to Gmail, Outlook, or iCloud. MailXP solves this with professional-grade deliverability.

A control layer on top of FlexQuota.

• Soft Cap: Notifies admins when usage reaches a threshold, but allows growth to continue.
• Hard Cap: Stops mailbox expansion at threshold until the admin takes action.

Why it matters: Gives IT full control over costs and growth. Entry-level plans may use Hard Caps, while premium plans can run fully unlimited.

Dynamic storage allocation model. Instead of fixed quotas, each mailbox can:

• Start small and auto-expand with usage
• Scale flexibly without admin intervention

Why it matters: Prevents wasted resources. Customers pay only for actual storage consumed, not for pre-purchased capacity.

European data privacy and cybersecurity standards. MailXP:

• Provides region-specific data residency
• Ensures regulatory compliance “out of the box”

Why it matters: Avoids heavy fines and builds trust with European businesses that handle sensitive data.

A low-activity account for employees who only occasionally check email. Examples: field workers, operational staff, or shift employees. They:

• Rarely initiate conversations
• Mostly receive internal updates
• Generate minimal load on the system

Why it matters: In MailXP, Infrequent Users are important. Since those users don’t create much load on the platform you can create as much user as you can where you don’t pay for unused capacity, unlike traditional per-seat licensing.

MailXP runs as a fully managed solution.

• Zero setup — no server installation required
• Automatic updates and patches
• 24/7 monitoring of availability and security

Why it matters: Removes the operational burden of self-hosted mail servers, which require constant updates, monitoring, and tuning.

A high-activity email account, typically managers, executives, or staff who rely on email as a primary communication tool. They:

• Send/receive large volumes of messages daily
• Often attach heavy files, use multiple devices, and manage distribution lists
• Are more exposed to phishing and targeted threats

Why it matters: Power Users drive business communication but consume more storage and security resources. MailXP advises number of users for each service plan compared to the number of power users that plan can process.

Each customer gets their own isolated cloud environment.

• No noisy neighbors (other tenants consuming your resources)
• No data leakage risk from shared-SaaS

Why it matters: Enterprises and regulated industries (finance, healthcare) require data isolation. MailXP guarantees this by design.

A modular policy engine to define how security behaves.

• Rule-based logic: e.g., “If sandbox verdict = malicious → quarantine”
• Granular control: per domain, per user, or per group

Why it matters: Gives admins flexibility. Security is not one-size-fits-all — MailXP adapts to organizational needs without external tools.

An advanced detection system for suspicious files, links, and attachments.

• Runs behavior-based dynamic analysis
• Converts findings into a global threat hash database
• One customer’s detection → protection for all users

Why it matters: Creates a “network effect” in security. Even if only a subset of customers enable Sandbox, the entire MailXP platform becomes stronger.

Built-in URL rewriting and continuous link scanning.

• Suspicious links are proxied through MailXP’s security servers
• Rescanned every time a user clicks (1 hour later or 1 month later)

Why it matters: Protects against delayed-activation phishing attacks where a safe-looking link turns malicious after delivery. Few providers offer this level of ongoing protection.

MailXP removes artificial boundaries on:

• Number of domains
• Number of mailboxes
• Storage capacity

Why it matters: Traditional SaaS tools force customers to buy licenses or storage blocks. With MailXP, growth is never limited by vendor constraints.

No per-seat licensing, no hidden fees, real cloud benefits for the e-mail service.

• Pay only for the platform + consumed storage + messages you sent
• All Users remain free

Why it matters: Predictable, fair billing. Eliminates the waste of paying for dormant accounts or unused seats.

MailXP integrates multiple detection sources:

• Commercial antivirus
• Open-source threat feeds (ClamAV, YARA)
• Zero-day and zero-hour analytics
• Nation-specific CERT intelligence

Why it matters: Blending multiple sources reduces blind spots. MailXP’s self-developed engine adapts faster than single-vendor security stacks.
