GAYLORD, MI — March 16, 2004 — Deerfield.com, an International provider of security and messaging software, announced today the release of VisNetic MailServer 7 and VisNetic GroupWare, a separately licensed component that allows users to share calendars, notes, tasks and address books via MS Outlook and a web-based client.

With GroupWare, VisNetic MailServer is now the functional and affordable answer for small and medium sized businesses looking for the same level of integration and flexibility found in Microsoft Exchange and Outlook, without the prohibitive deployment and maintenance costs.

VisNetic MailServer is a high performance email server for Windows. It features a built-in anti spam engine that utilizes three proven spam filtering technologies—a powerful Bayesian filter, the SpamAssassin rules-set and a challenge-response system. No other mail server available today offers this comprehensive array of spam filtering tools natively.

VisNetic MailServer also features:

• Integrated support for the VisNetic AntiVirus Plug-in, powered by Kaspersky Labs
• A built-in Instant Messaging server supporting its native Jabber protocol and access to ICQ, AIM, MSN and Yahoo Messenger via a single client
• A Web mail server featuring multiple skins, a customizable web interface and support for multiple languages
• Support for VisNetic GroupWare, a collaboration solution designed specifically for use with VisNetic MailServer

The VisNetic GroupWare component creates a collaborative workspace from which employees can share information centrally while minimizing redundancy, maximizing productivity, managing daily duties and appointments and increasing mobility. GroupWare users have access to shared data from any location on the Intranet, or Internet, via Outlook, VisNetic WebMail or any enabled application. VisNetic GroupWare also supports notifications through Instant Messaging, a feature not available in other products.

“By adding support for our new collaboration solution to VisNetic MailServer’s existing web mail and instant messaging capabilities, we now offer a messaging solution that provides much more than the ability to host your own corporate email,” said Mike Deerfield, CEO of Deerfield.com. “This messaging constellation also has the potential to boost employee productivity, allowing individuals to share calendars, tasks and contact data electronically, communicate instantly without leaving their desks and connect to mission-critical email correspondence via a web browser from anywhere in the world,” Deerfield.com said. “At the same time, its security features will protect the organization from destructive, potentially catastrophic viruses and offensive spam that can result in lost productivity and corporate liability issues.”

Pricing and Availability

VisNetic MailServer and VisNetic GroupWare are now available. VisNetic MailServer 7 is a one-time, license-based software solution. Pricing is based on number of users and is scaled to fit the financial needs of any organization, starting at $130.00 USD for a Plus 6-User license.

VisNetic GroupWare is separately licensed functionality contained within VisNetic MailServer. License options are based on user size and start at $60.00 USD for 6-users.

Note, VisNetic GroupWare and MailServer user license size may differ. For example, a company with 100 employees may wish to provide email accounts for all, but limit collaboration tools to a select, smaller group of employees (managers, project leaders, etc.). In this example, a VisNetic MailServer Pro 100-user license and a VisNetic GroupWare 12-user license could meet the organization’s needs.
