WHMCS PolarisMail Module is a commercial WHMCS server module developed by Thexyz Inc. It connects WHMCS to the PolarisMail / EmailArray admin API and allows providers to automatically create, suspend, unsuspend, terminate, and manage individual mailbox accounts.

Unlike traditional email hosting modules that expect each customer to use a custom domain, this module is designed for selling email accounts on one or more approved shared domains. You can whitelist house domains such as example.com, example.ca, or example.net, then let customers choose their mailbox handle during ordering.

The module includes a custom WHMCS client area experience where customers can manage mailbox passwords, generate webmail access, create aliases, and manage distribution lists depending on the limits configured for the product.

Why This Module Is Valuable

WHMCS is excellent for selling hosting, domains, and custom-domain email, but many providers also want to sell mailbox accounts on their own branded domains. This module fills that gap by turning WHMCS into a storefront for individual mailbox accounts.

Instead of manually creating mailboxes, aliases, and lists for every customer, the module automates the provisioning workflow and gives customers self-service controls inside the WHMCS client area.
