MailChannels cPanel Plugin

The MailChannels cPanel Plugin is a tool designed for web hosting providers that integrates with cPanel and WHM (Web Host Manager) to manage and provision email security for hosting customers. Key capabilities include: **Domain Protection:** Administrators can protect all or select domains directly from the WHM admin interface, without needing to switch between separate management consoles. **Exim Configuration:** The plugin automatically configures Exim — the mail transfer agent commonly used in cPanel environments — with sender identification headers. This is intended to protect email sender reputation and improve outbound email deliverability. **Compromised Account Detection:** The plugin includes functionality to detect compromised accounts within the hosting environment. **Single Sign-On for End Users:** Hosting customers can log in to manage their own email filtering settings directly from within cPanel, without requiring a separate MailChannels account or login credentials. The plugin is targeted at web hosting providers who use cPanel and WHM to manage customer accounts, enabling them to provision MailChannels email security services more efficiently.
