Messaging vendors Scalix and Gordano this week plan to introduce upgrades to their messaging servers that provide better monitoring tools and archiving options and offer customers a range of capabilities designed to improve high availability, cross-platform feature support and Web-based interfaces.

Scalix is rolling out Version 10 of its Linux-based server, of which the Enterprise Edition includes clustering features to support fault tolerance. The company has added support for Apple's iCal to provide calendar integration with Microsoft Exchange, Lotus Notes and Novell GroupWise.

Also new is ScalixConnect for Evolution, which provides integration with the Evolution messaging client for Linux desktops. Wireless support has been improved, with new client features and background synchronization.

The Scalix Web Access client also has been upgraded with an integrated address book and personal distribution lists.

Scalix makes it possible to host many Scalix domains on one server and has 64-bit support for the Fedora Core OS, Red Hat Enterprise Linux, SuSE Linux Enterprise Server and SuSE Linux OSS 10. Scalix costs an initial $60 per user, followed by an annual charge of $12 per user.

Gordano is expanding the capabilities of its Gordano Messaging Suite (GMS), which runs on Windows, Unix and Linux. Its new features include AJAX-like additions to its browser-based client that will cache e-mail messages to improve performance. The company is adding hooks for SNMP so users can integrate GMS with management tools.

A new API for its External File Manager will let users put the GMS message store on a variety of storage platforms, including databases and archiving software, and will let them monitor their messaging system with more sophisticated tools than traditional message logs. Users will also be able to integrate GMS with VoIP systems to get voice mail in their in-boxes.

GMS is priced at $34 per user for 1,000 users. Scalix and Gordano compete with CommuniGate, IPSwitch, Mirapoint, Rockliffe and Sendmail.
