ZixIt Corporation Signs Law Firms Vial, Hamilton, Koch & Knox, L.L.P. And Smith, Underwood & Perkins, P.C. to Use ZixMail(TM)

DALLAS, Jan. 6 /PRNewswire/ -- ZixIt Corporation (Nasdaq: ZIXI) announced today that two prominent Texas law firms -- Vial, Hamilton, Koch & Knox, L.L.P. and Smith, Underwood & Perkins, P.C. -- have each signed an agreement to use the ZixMail(TM) secure messaging system in their law practices. ZixMail, which allows any email user to send and receive encrypted and digitally signed email communications, is based on ZixIt Corporation's Digital Signature and encryption technology.

The law firms will use ZixMail to send confidential email communications, and in doing so, will better protect their clients' privacy. ZixMail has approval from the U.S. Department of Commerce for international use, allowing both law firms to communicate securely with their domestic and international clients.

"In order to effectively service our clients in the year 2000 and beyond, we needed to implement the best technology available to make our email communications secure. ZixMail will allow us to send sensitive materials via email and ensure attorney-client privilege, whereas until now, we have used normal email, overnight shipping, or even the fax machine. Our ZixMail communications are a much more secure form of doing business, since with its certified receipt feature, we know when the intended recipient has actually opened and read the ZixMail message," said Larry Bridgefarmer, partner with Vial, Hamilton, Koch & Knox, L.L.P.

Speaking on behalf of Smith, Underwood & Perkins, P.C., Timothy S. Perkins, name partner with the firm, echoed that sentiment, "The role email plays in our practice is substantial, both internally and externally. We wanted to implement an email security system that would allow us to continue using our current email applications while providing our clients with privacy and protection. Moreover, we do not have time for extensive training. ZixMail is so easy to use that I don't foresee any downtime at all. ZixMail meets our stringent requirements on all counts."

Doug Kramp, chief executive officer of ZixMail.com, Inc., commented, "As law firms and other businesses expand their electronic communications, they will want to ensure that sensitive information remains private. ZixMail ensures that email is protected against interception and tampering. By establishing a corporate ZixMail account, a business can ensure the accuracy and completeness of its business records and its employees' business communications. ZixMail is the optimal solution."

ZixMail is currently available, in beta release, for download from the ZixMail Web site at www.zixmail.com.
