DOD supports Unix messaging with user agent

Nexor Inc. has released its Messageware Defender for Motif, a military-grade user agent
for Unix platforms that are part of the Defense Department’s Defense Message System.

Defender now is the only mail client that supports military messaging standards on Unix
workstations, company officials said.

Nexor’s Messageware server is already certified for DMS use, but the Defender
client has yet to undergo interoperability testing, said Tony Roadknight, senior technical
consultant for Nexor of Gaithersburg, Md. He said Defender’s beta testers included
several intelligence agencies that have large groups of Unix users.

Although Unix is a shrinking niche for DMS, it still controls many mission-critical
systems, Roadknight said. The military is committed to migrating to a Microsoft Windows
environment, but transferring Unix performance and essential applications to Windows is

Defender mirrors the Microsoft Outlook interface under the Motif graphical environment
for Unix platforms. Defender supports DOD’s Message Security Protocol and the X.400
messaging protocol. A modular architecture accepts different plug-in security libraries.

Defender is available for Hewlett-Packard HP-UX, IBM AIX and Sun Solaris, and Nexor can
port it to other Unix platforms, Roadknight said.

It costs about $110 per seat under a number of licensing arrangements.
