Nexor Product Approved for DMS Certified Compliant Products List; Messageware MTA Passes Rigorous Testing to Become First Track II Message Transfer Agent to Appear On List.

GAITHERSBURG, Md.--(BUSINESS WIRE)--June 23, 1998--NEXOR, an international provider of mission critical messaging and directory products, today announced that its Messageware(R) MTA for Microsoft Exchange 4.0 has been approved for registration on the Defense Message System (DMS) Compliant Certified Products List (CCPL). The CCPL is a register of DMS products that have been tested for DMS functionality, interoperability, security, and performance by the Defense Information Systems Agency's (DISA) Joint Interoperability Test Command (JITC).

"With NEXOR's MTA already at the heart of many DMS security products such as Multi-Function Interpreters from CommPower and California Microwave, the Xerox Profiling User Agent and the Wang High Assurance Guard, it was inevitable that we would pursue DMS certification on our own merits," said Frank McLallen, vice president and general manager, US Operations of NEXOR. "We are very excited to be a part of the DMS certified family of secure, mission-critical products and will continue to demonstrate our commitment to the defense community by submitting more NEXOR products for CCPL testing later this year."

NEXOR's Messageware MTA for Microsoft Exchange 4.0 is a high performance, dual protocol (X.400 and SMTP) message switch that allows for the transfer of electronic mail between disparate messaging systems. It is the second Track II product to be registered on the CCPL. Track II refers to products that are not on the Lockheed Martin DMS contract but are tested to ensure interoperability with the DMS infrastructure being built by Lockheed Martin. To be approved for inclusion on CCPL, Messageware MTA passed DMS Functional, Interoperability, Security, and Performance (FISP) testing.

Messageware MTA is ACP-123 compliant, which defines support of the military standard P772 and also meets the NATO standard, STANAG 4406.

The DMS program was implemented by DISA to replace the aging AUTODIN messaging system at federal and military agencies. With the primary objectives of reducing costs and increasing security, the DMS program includes testing and certification of Commercial Off the Shelf (COTS) products for DMS use.

The Messageware MTA is part of a family of powerful messaging and directory products aimed at markets where high assurance standards-based messaging is vital, such as defense and government. The Messageware family includes an X.500 directory server; Directory Guardian (a directory firewall); an X.500 to World-Wide Web Gateway; and user agents for Unix Motif and Microsoft Exchange environments. NEXOR plans to submit the Messageware X.500 directory server and user agent products for CCPL testing later this year.
