Mailcow Module for WHMCS Module by WHMPress

The Mailcow Server Module is a powerful integration tool that bridges WHMCS with Mailcow, the popular and feature-rich mail server suite. Designed for hosting providers and IT service companies, it streamlines email provisioning, automates account management, and delivers a professional, reliable email hosting experience.

Whether you’re offering standalone email hosting or bundling it with other services, this module helps you manage resources effortlessly, boost sales with flexible add-ons, and provide clients with a smooth, self-service experience.

As a WHMCS Product Module

  • When configured as a WHMCS product module, it enables automatic provisioning, suspension, termination, and management of Mailcow email services.
  • Hosting providers can offer enterprise-grade email hosting with minimal manual intervention, ensuring efficiency and scalability.

Addon for Mail Hosting Expansion

  • This allows providers to scale resources based on demand, generating new revenue streams while keeping clients’ email infrastructure responsive to their needs.

Flexible Integration with Other Services

  • One of the module’s strengths is its adaptability.
  • You can integrate it with other hosting products — such as shared hosting or VPS plans — as an independent, fully functional mail service.
  • This lets you enhance your existing offerings without complex configurations.

Configurable Options & Dynamic Quota Management

  • The module offers Configurable Options for mailbox count and quota size, allowing you to create tailored packages for different user needs.
  • Default Mailbox Quota – Define the storage per mailbox.

Usage Metrics & Billing Insights

  6. Usage-Based Billing:

  7. Reseller-Friendly:

    • Allow resellers to manage their own clients with delegated control.

  8. API-Driven Reliability:

    • Secure communication between WHMCS and Mailcow.

  9. Detailed Admin Controls:

    • Suspend/unsuspend, reset passwords, adjust quotas from WHMCS.

  10. Manage Mailboxes:

    • Both Admin and Client can Create/Delete/Change Passwords of the Mailboxes for their Domain directly from WHMCS.
