Are you a Web Host, Email Service Provider, or ISP? CrossBox Cluster lets you provide a superb communication experience to all your users across any number of servers. It can plug and play into your existing infrastructure without requiring a single change in your current server setup.

Cluster Mail

Many servers mean a lot of confusion and many IMAP, POP3, and SMTP hostnames. With CrossBox Cluster, you can have a single, easy to remember hostname for all your customers — for example,

Cluster Webmail

What do you like more: each server with its own Webmail URL or a single Webmail URL for all your servers? Everyone told us it's the latter, so we made it possible.

Scale Indefinitely

With CrossBox Cluster, you can both add and remove servers seamlessly within the admin area. The changes you make automatically propagate to your central IMAP/SMTP/POP3 hostname and Webmail URL.

Mix Different Servers

A cluster can contain any number or combination of Standalone, DirectAdmin, cPanel or Plesk servers — allowing you to unify communication experience for all your customers, across different server types and configurations.
