Merak Mail Server is available in multiple versions, as are additional value-adding modules such as the Merak GroupWare Server and Merak Instant Anti-spam. The Standard and Professional version are license unlimited (unlimited domains and unlimited users per machine).

Merak Instant Anti-spam (MIAS) is a hybrid technology that, claims the vendor, approaches near 100% accuracy in the identification of Spam (in live production installations) and near 0% false positives. MIAS provides flexibility to meet any organization's requirements, from Anti-spam/Anti-virus gateway for an Exchange network, to an entire communications solution for small, medium and large corporations and ISPs. MIAS allows you to manage each Spam message on an individual basis if required.

In addition to its incorporated Anti-spam technologies, MIAS can also run in a "self learning" mode. This mode allows the system to learn from mistakes by allowing users to teach the system by feeding it known Spam that is received by your organization and then back to the Merak Instant Anti-Spam System.

A free trial mode download is available. A MIAS license is available for all Merak Mail Server versions and special pricing for Spam Bundle Packs and Merak Mail Server Competitive Upgrade Bundles are also available.
