This status code in ZixIt Signature Manager indicates that a ZixIt Signature has been successfully created and posted to the ZixIt Worldwide Signature Server, then confirmed by the user.

The status of your ZixIt Signature is stored at the ZixIt Worldwide Signature Server and viewed on your local PC using the ZixIt Signature Manager.

See confirmation.

A feature of ZixMail that enables you to store frequently used individual email addresses or email groups.

You can specify a nickname for each email address or contact. For example, when you add John Henderson (whose email address is JHenderson@domain.com) to your address book, you can specify his name as John. When you compose ZixMail messages, you can type John as the recipient.

Email addresses with "active" ZixIt signatures are shown in bold type in the address book. Email addresses without currently active ZixIt Signatures are shown in gray type (dimmed). You may press the Update Inactive Codes button to obtain the latest status for your address book entries.

ZixMail has a feature to import email addresses from the address books of most major email programs, so you can easily add all of your contacts to your ZixMail address book.

See email group.

See exporting Signatures.

A confirmation ZixMail message automatically sent to the sender when the recipient opens the message for the first time. The confirmation arrives as a ZixMail message with the designation ZCR: at the beginning of the subject, followed by the original subject field.

The "certified receipt" contains the original digitally signed time-stamp showing the time that the original message was sent. A second digitally signed time-stamp shows the time at which the message was opened. The Message ID associated with the original message is also included.

The process of confirming your email identity in order to set a newly created ZixIt Signature to active status. Also used to confirm changes to or deletions of your ZixIt Signature. You must have an active ZixIt Signature in order for others to send encrypted ZixMail messages to you.

Your ZixIt Signature, when first created, is initially set to "pending activation" status. At that time, the ZixIt Worldwide Signature Server immediately sends an activation confirmation email message to your email address. You must respond to this confirmation email within 24 hours or your newly created ZixIt Signature will be removed from the ZixIt Worldwide Signature Server.

The activation process ensures that no one else can create a ZixIt Signature for your email account. Only you can receive and respond to the confirmation email message sent to your email address. Your ZixIt Signature will be set to active when you respond to the confirmation email message.

The same email confirmation process is used to verify email address ownership for changes to or deletions of a ZixIt Signature.

Someone with whom you correspond by email, an entry in the ZixMail address book.

See deletion.

The process of changing an encrypted ZixMail message into a readable email message.

See encryption.

The process of removing a ZixIt Signature from the ZixIt Worldwide Signature Server.

When you choose to delete a ZixIt Signature from the ZixIt Worldwide Signature Server, you will no longer be able to digitally sign ZixMail messages with that particular ZixIt Signature. Also, others will no longer be able to send encrypted ZixMail messages to that particular email address.

The deactivation process begins when you choose to delete a ZixIt Signature. You deactivate a ZixIt Signature in the ZixIt Signature Manager application. The ZixIt Worldwide Signature Server will immediately send a deactivation confirmation email message to your email address. You must respond to this confirmation email within 24 hours or your ZixIt Signature will not be deactivated.

The deactivation process ensures that no one else can delete a ZixIt Signature for your email account. Only you can receive and respond to the confirmation email message sent to your email address. Your ZixIt Signature status is set to Inactive when you respond to the confirmation email message.

It's a good idea to deactivate a ZixIt Signature before you change your email address. Your email account must still be active in order to confirm that you want to deactivate the ZixIt Signature.

See ZixIt Signature.

A ZixMail message that has been saved in the Drafts folder but not yet sent. You can save a message as either an encrypted or an unencrypted draft. Encrypted drafts are secured with your ZixIt Signature, and you are required to enter your Signature Phrase in order to view or send that draft. Unencrypted drafts are not secured and can be viewed or sent by anyone with access to your PC.

Standard lines of information that can be added to the end of every ZixMail message that you send. Like a digital business card, your email ID can include your name, address, organization name, telephone and fax numbers, email addresses, and web site addresses.

ZixMail includes this email ID information at the end of the ZixMail message only when the Attach Email ID checkbox is selected. The email ID information is included inside the encrypted message, so only the intended recipient can see it.

You can edit your email ID in either ZixMail or the ZixIt Signature Manager.

A collection of one or more contacts in your ZixMail address book. You can use email groups to send a single message to multiple recipients.

For example, if you frequently send the same email message to everyone in your family, you can create an email group called Family and add each contact that would normally receive family news. When you compose a ZixMail message to the family, you can simply type or select Family as the recipient, and all family members will receive the message.

If some email group members do not have active ZixIt Signatures, the message is not sent to them, but a copy of the message is stored in the Drafts folder for later delivery.

The mathematical process of converting an email message into a ZixMail message, making it unintelligible to unauthorized users. By reversing the mathematical process using his or her ZixIt Signature (decryption), the recipient can read the message.

ZixIt encryption technology uses 1024-bit Public and Private Signature Codes (keys). ZixMail message encryption uses Triple-DES with three independent keys.

The U.S. Department of Commerce has issued worldwide encryption export approval for ZixIt-enabled software such as ZixMail. Countries excluded from the approval are Cuba, Iran, Iraq, Libya, North Korea, Serbia, Sudan, Syria, and the Taliban-controlled areas of Afghanistan.

This means that your London, Tokyo, and New York offices can all use the same strong encryption offered by ZixMail.

See decryption.

Part of the process of copying or moving your ZixIt Signature to another PC.

The ZixIt Signature Manager enables you to select one or more ZixIt Signatures and then to create an encrypted export file that contains those Signatures. This export file may then be used as a backup of your ZixIt Signature and can be used to import your ZixIt Signature to another PC.

Export files end with the extension .zkx (ZixIt key Export).

See importing Signatures.

A file that is attached to a ZixMail message. Any number of files may be attached and the attachments may be of any type, such as .doc or .xls. All file attachments to a ZixMail message are both encrypted and compressed.

The ZixIt Signature Manager and the ZixMail applications use certain standard file name extensions:

A standard text file you create that contains a list of files (one per line) that you want to attach to a ZixMail message. This allows for repetitive file transfers to be handled very efficiently.

When you create a file list, you specify the complete path for each file you want to attach. Wildcards are allowed. For example, a file named "research_files.txt" could be created with the following contents:

Sending a ZixMail message and attachments that you received to another ZixMail recipient. Any forwarded ZixMail message will be re-encrypted for the next recipient.

See SMTP (Simple Mail Transfer Protocol) server.

Part of the process of copying or moving your ZixIt Signature to another PC.

The ZixIt Signature Manager enables you to import one or more ZixIt Signatures from another PC. The import file must previously have been created using the export feature on the other PC.

Import files (also called export files) end with the extension .zkx (ZixIt key Export).

See exporting Signatures.

This status code in ZixIt Signature Manager indicates a ZixIt Signature that was previously "active" but now has been changed to a different status, such as revoked, deleted, deactivated, suspended, removed, or hidden. While Inactive, a ZixIt Signature may not be used to digitally sign outgoing ZixMail messages. Also, you cannot send ZixMail encrypted messages to a recipient with an inactive Signature status.

The status of your ZixIt Signature is stored at the ZixIt Worldwide Signature Server, but the status may be updated (using the Update Status button) and viewed on your local computer using the ZixIt Signature Manager.

A secret phrase used to encrypt a ZixIt Signature export file. When importing the file from another PC, you must enter the protection phrase exactly as you specified it when you created the export file.

See exporting Signatures, importing Signatures, Signature Recovery.

See Signature Recovery.

A file created during setup that enables you to recover a copy of your ZixIt Signature in the event that you have forgotten the Signature Phrase, your hard drive is corrupted, or your PC is replaced, lost or stolen.

When you create or change your ZixIt Signature for a particular email address, you are offered the opportunity to back up a copy of your ZixIt Signature to a disk. Because this file can be used to access ZixMail messages on your PC, it is important to store the disk with your Recovery File in a safe, secure place.

See Signature Recovery, exporting Signatures.

See ZixIt Signature.

Your Signature Phrase is a secret phrase that you make up and remember when you create your ZixIt Signature. You must type your Signature Phrase in order to digitally sign outgoing ZixMail messages or to open incoming ZixMail messages.

Your Signature Phrase must be at least one character long but no more than 128 characters. A Signature Phrase is case sensitive and may contain spaces and any characters.

A server that routes email messages that you send to the recipient's email inbox. You may specify an SMTP server to use for each of your ZixIt Signature email addresses. The SMTP server name usually appears in the format such as, smtp.domain.com.

You can usually find your SMTP server name in the options for sending mail in your regular email program (such as Microsoft Outlook, Lotus Notes, or Qualcomm Eudora).

If you use a proprietary or Web-based email program (like AOL, HotMail, or Yahoo), your email messages are not normally routed through a known SMTP server. You may elect to use the ZixMail HTTP/SMTP server relay option to route these messages.

A certified time-stamp is attached to every ZixMail message. When ZixMail retrieves the email recipient's Public Signature Code (public key) from the ZixIt Worldwide Signature Server, it also retrieves a certified time-stamp for the ZixMail message.

The time-stamp is "certified" because the ZixIt Worldwide Signature Server combines a time-stamp (set by an Atomic clock), a hash (a short mathematical representation) of the ZixMail message being sent, the "status" of both the sender's and recipient's ZixIt Signature, a super root certificate (signed by four root keys), and then the combination is digitally signed by the ZixIt Worldwide Signature Server.

This combination ensures that it is impossible to tamper with or change the time-stamp and that the time-stamp cannot be used on any other ZixMail message.

The email message itself is not sent to the ZixIt Worldwide Signature Server.

A digital signature from Zix Corporation, providing irrefutable digital identification—one that is just as personal and unique as your handwritten signature.

The Zixit Signature is comprised of a set of encryption codes that enable you to digitally sign outgoing ZixMail messages and to decrypt incoming ZixMail messages. A ZixIt Signature can be created for an email address in about 60 seconds using the ZixIt Signature Manager.

Your email address works with these three other components to form your unique ZixIt Signature:

The Zix Corporation central utility application that handles creating, changing and deleting ZixIt Signatures. The software is bundled with ZixMail and includes functions for exporting, importing and recovering ZixIt Signatures.

The Zix Corporation application that enables Internet users worldwide to send and receive encrypted and digitally signed email communications without changing their existing email addresses or their existing email systems.

An encrypted and digitally signed email message that can only be opened and read by the intended recipient.

The sending option for ZixMail messages to be delivered to recipients over a secure (SSL) connection or by alternative secure methodology, such as PGP/MIME or S/MIME (forthcoming). Attachments, if any, may be scanned for viruses and then downloaded individually over the SSL connection.
