Mailcow WHMCS Self-hosted Mail Solution | BUILT BY ME FREE FULL SOURCE CODE 1.1.1

WHMCS ↔ Mailcow Integration Module

Turn Your WHMCS into a Full-Fledged Email Hosting Panel

This module was designed for hosting providers who want to deliver their own branded email service—with the same ease of use customers expect from the big players, but entirely under your control.

Because Mailcow is open-source, you can install it on your own server and own the entire infrastructure. The addon links WHMCS to Mailcow, automating domain provisioning and unlocking a clean, user-friendly Client Area where customers manage everything themselves.

In short: you become the email provider. Clients create, edit, and manage mailboxes without tickets or extra logins.

Full Multilingual Support
