ZSentry Registration
Frequently Asked Questions

What is the ZSentry Name Protection Policy? The ZSentry Name Protection Policy is part of the email security services provided by ZSentry. During registration procedures, if elements of the Name, Email Address or Subscriber Name / Organization match elements of certain Names, Email Addresses or Organizations that are registered with ZSentry or have been subject of abuse, this Policy requires justification to use those identifiers, for our review.

We apologize for any inconvenience caused by this Policy, which is necessary to protect our users from abuse, spam, spoofing and phishing.

How do I submit a name for review? The ZSentry Name Protection Policy is implemented using a simple procedure for review. If elements of Your Name, Email Address or Subscriber Name / Organization match elements of certain Names, Email Addresses or Organizations that are registered with ZSentry or have been subject of abuse, we will send you a first email asking your justification to use those identifiers. If your justification is accepted, you will receive a second email with your Usercode. We may need to contact you for further information.

What is verified by ZSentry/Zmail challenge-response authentication by email? ZSentry provides high-value identity and address verification, with a multilevel, multi-channel, varied, adaptive, and ongoing (ie, also after registration) evaluation. For how it is done, click Identity Verification

What if my email address is also registered by someone else?
When you registered at ZSentry and activated your account, ZSentry authenticated your email address using your Usercode as an unpredictable challenge-response. This effectively protects your email identity for sending and receiving email. ZSentry also blocks your email address from further registration. But even before you registered your email address at ZSentry, if someone would enter your email address and would try to register using it, she would not be able to receive the ZSentry Usercode that is sent to that email address. Therefore, she would not be able to log in using that ZSentry Usercode to activate the account. This means that you can register and activate your account without any interference.

Can ZSentry also protect the recipients of my messages? Yes, in multiple ways. First, ZSentry protects the privacy of your email messages, which may be important for your recipients (for example, if you want to send their health or financial records by email). In addition to protecting the privacy of email messages, with ZSentry every message, every sender and every recipient are authenticated every time.

When you use ZSentry you are assuring your recipients that the email is really from you, not some spoofing email pretending to be from you. Likewise, when the recipient registers to read your message, which has no cost, the recipient and her email address will be tested by the same challenge-response procedure that was used to authenticate you and your email address. This assures you and the recipient that your message cannot be decrypted by anyone else. Your message will be safely delivered.

Can ZSentry help against spam, spoofing and phishing? Your encrypted and authenticated ZSentry should easily stand out from the clutter of spam, virus and phishing emails, allowing your mail to be read with ease of mind and priority -- a win-win situation for you and your recipients.

PREMIUM messages are sent also with an encrypted PREMIUM Seal, visible to recipients. Recipients will know that you have a PREMIUM commercial account and that you took care in sending a secure, authenticated message to them -- and that's why the message is important.

How about password security?
ZSentry is not as dependent on password quality for security, as conventional systems are. With ZSentry technology, passwords are not at risk anywhere (not even encrypted or in digest form) and they are paired with an unpredictable ZSentry Usercode that is also not at risk anywhere. Nonetheless, it is recommended that ZSentry passwords should include at least one control or punctuation character. All of the characters !@#$%^&*()_-+=[]|\;:"?/,.< >`~' and space can be used in ZSentry passwords (space cannot be used at the beginning or end of a password).

ADVANCED PASSWORD USE: Using ANSI codes from #32 to #255 (keyboard ALT-number, no space at the start or end of a password) enables more than 132 bits of entropy with just 13 ZSentry Password characters (and the Usercode). The conventional difficulty for using ANSI codes in passwords is solved by the ZSentry function Password Peek (during signup and login). You can easily see and verify what you typed before you submit, even for ANSI CODES such as ALT-0159 for Ÿ (Latin Capital Letter Y With Diaeresis).

Pseudonym usage with ZSentry & Privacy Protection
You may declare a pseudonymous identity for your Name and Email Address, only, provided that you conform to all provisions of the PREMIUM/BASIC ZSENTRY TERMS OF SERVICE, available at this site and shown to you during registration. In particular, you shall not create a false identity for the purpose of misleading others as to your identity or anything related to a message, including but not limited to source and contents. By providing you with the possibility of using a pseudonym for your Name and/or Email Address, ZSentry allows you to further protect your privacy, if you so desire. This facility is provided for the convenience of users and must not be abused.

Pseudonym Definition:
[Gr.,=false name] A pseudonym is a name assumed, particularly by writers, to conceal identity. A writer's pseudonym is also referred to as a nom de plume (pen name). Famous examples in literature are George Eliot (Mary Ann Evans), Mark Twain (Samuel Clemens), Lewis Carroll (Charles Lutwidge Dodgson), O. Henry (William Sydney Porter), Stendhal (Marie Henri Beyle), and George Sand (Mme Amandine Aurore Lucie Dupin, baronne Dudevant). The Internet popularized the use of pseudonyms as way to preserve privacy, for example by using email addresses and "screen names" that do not resemble the person's name. Pseudonyms are not illegal in themselves - it is the improper use of pseudonyms that could be actionable. A pseudonym can provide you with anonymity provided that the pseudonym cannot be linked to your real identity.
