What is it

This is a collaborative protection system against disposable email addressing (DEA). More explicitly,

• Protects site owners' biggest assets; userbase and emails
• Prevents userbase contamination by fake accounts
• As critical as email validity check
• Stops people registering your services with disposable email accounts like jetable.org, pookmail
• Detects public accounts (spread from sites like bugmenot.com) and bans them
• Working principle is similar to spam blacklists like spamhaus.org; power of masses
• Totally free, your donations are welcome

Technically speaking, this is a web service that provides you API to check email credibility against disposable hosts and fake accounts. We currently support only REST, XML-RPC protocols and PHP serialization but SOAP and JSON are on the way as well. You can access our services with any programming language you want. API Kits for various languages are here to make it easier to reach our services.

How to use it

1. Check if there is an API kit for your programming language, if there isn't, connect to our servers manually.
2. Add a few extra lines to your email validation function which is called from your member registration page. The following is an example in PHP language:
   <?php
..
function checkEmail($email) {
  include_once("undorg/php/rest/undisposable.inc.php"); // include the API kit
  if(!undorg_isDisposableEmail($email)) { // check if disposable email
     .. // old procedures remain here
  } // add this line to close the conditional statement
}
..
?>

3. That's all. Very simple...

Helping Us

This is a collaborative project. We need your help:

• Report any uncovered disposable email hosts you discover.
• Provide API kits for lacking programming languages and protocols
• Increase awareness, submit how-tos to security sites, spread the word
• Sponsor bandwidth

FAQ

1. Is it really free? Will you charge me in the future? What about if I wanna use it with my commercial projects?
   Yes, it's totally free and will remain so. You can use it in your commercial projects as well.
2. But undisposable email accounts protect me from spam mail!!
   Yes, we love undisposable emails too. They are good to put your emails in public places like forums, but none of us have right to cheat service providers; use trusted sites, don't check "do you want promotional emails" boxes and that's all, you won't receive spam.
3. How many DEA hosts you have in your database?
   Hundreds and still counting... We even include local DEAs.
4. How it works?
   This a 3-tiered system. In the first tier, we add DEAs manually. In the second tier, our spiders crawl search engines deeply and report us suspicious hosts. In the third tier, we rely upon power of masses approach and manually evaluate your reports.
5. Which protocol, which programming language should I use?
   Use whatever you want... Doesn't matter. But as our services are still in their infancy, try to use **Stable** flagged ones; they are well tested.
6. Are API kits free as well? Can I use them with my commercial projects?
   Yes, any API kit promoted on our site has to have a liberal license like LGPL or BSD or MIT. Viral licenses like GPL are not accepted as they may create conflicts with your commercial projects. So, feel free to use our API kits in any project of yours.
7. Are there any limits in requests I make?
   No, suspicious activities can be banned though. If we observe excessive numbers of requests coming from your domains, we'll contact you and wait for a response in 24 hours.
