DALLAS--Aug. 14, 2000--ZixIt Corporation (Nasdaq:ZIXI) introduced today a new version of ZixMail(TM), its secure document delivery, private email, and message tracking service. This new version offers seamless integration with Outlook(R), the Microsoft email and personal information management product. The new Outlook add-in enables users to easily send secure and authenticated email messages directly to anyone in the world. ZixMail for Outlook, which is free until the end of the year, is available now at www.zixmail.com.

David P. Cook, chairman and chief executive officer of ZixIt Corporation, said, "The release of this Outlook version greatly enhances the market opportunity for ZixMail. The ability to compose and send ZixMail messages in Outlook will make sending encrypted email as convenient as sending regular email. The new ZixMail `Z' button in Outlook enables users to select any email recipient from their Outlook address book and to know that their message will be securely delivered - even if the recipient is not a ZixMail user."

If the recipient is a ZixMail user, the encrypted and digitally signed message will be delivered directly to the recipient's email inbox. If the recipient is not a ZixMail user, the message will be routed to ZixIt's secure messaging portal, SecureDelivery.com(TM), where it will be stored securely until retrieved by the intended recipient via a secure (SSL) Web-browser connection.

ZixMail provides Outlook users with the following set of powerful features:

-- Simple "add-in" installation,

-- Ability to send secure messages to any email address in the

world immediately,

-- Strong 1024-bit public key encryption to ensure that only

intended recipients can open ZixMail messages,

-- Digital signature technology to authenticate the sender of

each ZixMail message and to ensure the integrity of the

message itself,

-- Real-time distribution and validation of public keys to

eliminate the burden of manually storing and exchanging keys

with other ZixMail users,

-- External time-stamp on each message to irrefutably establish

the time the message was sent,

-- Certified delivery receipt that establishes the time the

message was opened, and

-- Compression of each message and all attachments to ensure

rapid transmission of the encrypted data.

ZixIt Corporation provides products and services that enhance security, privacy, and convenience for users of the Internet. Principal services include: SecureDelivery.com(TM) - an Internet secure-messaging portal, and ZixMail(TM) - a secure document delivery, private email, and message tracking service that enables users worldwide to easily send and receive encrypted and digitally signed communications using their existing email systems and addresses.
