smf-sav is a lightweight, fast and reliable Sendmail milter that implements a real-time Sender e-Mail Address Verification technology. This technology can stop some kind of SPAM with a spoofed senders e-Mail address.
Also it implements a real-time Recipient e-Mail Address Verification technology. It can be useful if your machine is a backup MX for the recipients domain or if your machine forwards all e-Mail messages for your domain to another (presumably internal) e-Mail server. Sendmail Sender Address Validator is written in C.
Main features:
- friendly hosts/networks whitelist;
- SMTP AUTH support;
- strictly RFC-2821 compliant MX callback engine;
- tolerance against non RFC-2821 compliant e-Mail servers;
- blocking of e-Mail messages with a spoofed senders e-Mail address;
- recipients e-Mail address verification with an authoritative e-Mail store in gateway mode;
- slow down of recipients e-Mail address brute force attacks in gateway mode.
Enhancements:
- Whitelisting by a PTR (reverse DNS) record was implemented.
- Whitelisting by an envelope recipient email address was implemented.
- The option to ignore tempfailed results of SAV was implemented.
- The option to refuse email messages from systems that dont accept the null reverse-path was implemented.
- Tempfail and fail results TTL settings were segregated.
- Progressive slowdown of brute force attacks on a recipients email address was implemented.

Disposable Temporary E-mail project provides the user with disposable e-mail addresses which expire after a certain time. The user can read and reply to e-mails that are sent to the temporary e-mail address within the given time frame.
Main features:
- Users can generate e-mail addresses
- Users can see their incoming e-mails
- Users can reply to e-mails
- Completely template driven
- Installation routine
How the script works:
With a click on a button the user generates a new e-mail address. That address will be stored in the database along with its creation time. The e-mail address is assigned to the user by a session cookie.
The user then uses the e-mail for any purpose where an e-mail address is required. Most commonly that will be some kind of registration.
In the background the script checks continuously for arriving e-mails. Once an e-mail that has been sent to a generated e-mail address arrives, the script displays it.

Postaci (Turkish word for Postman) is a multiplatform PHP webmail software which is database independent, IMAP/POP3, multilanguage(32 languages) and fully MIME compatible. While using POP3 mode to fetch messages it uses database fields to simulate IMAP folders, on which you can save, move, delete,read e-mail.
It is a easy to set up, really secure environment and been downloaded by more than hundred thousand users all around the world. It also is bundled with a simple adressbook, a notebook, a bookmark manager application.
Postaci includes multidomain(virtual) support. Domains are stored in a DB table and all users must be linked to a domain. It can be done at tblDomains and tblUsers tables at the database. If you have a single domain on your server you won t need to do this. There must be at least one domain at the database and its index should be 1. This is the default domain for any user. You can change your default domain at the tblDomain.sql file at the queries folder.
Enhancements:
- SMTP authentication for those who need to authenticate to send email.
- An Email Address field in Preferences allows you to manually set your From: email address.
- A problem in moving messages when using IMAP has been fixed.

eformmail project is a stand-alone CGI program that accepts an HTML form and emails it. The target email address is not buried in the HTML form, making it impossible for spammers to take advantage of this email address.
The output can be formatted by an XSLT processor, and form fields can be validated against a regular expression. A comprehensive manual is available.
Main features:
- Mail the contents of a form to an email address.
- The email address does not have to be present on the form, so it can not be used by email address harvesters in order to spam it.
- The contents of the email body that will be sent is completely configurable. eformmail can pipe the form data through an XSLT processor, so any formatting is possible.
- Supports both application/x-www-form-urlencoded and multipart/form-data encodings.
- It is possible to specify which fields must be validated. The contents should conform to the specified regular expression, else the email will not be sent.
- Single binary program. No PHP, Perl or other libraries needed.
- eformmail.cgi is protected against harvesting of web pages that might use it, in order to exploit it by sending spam through that web page.
Enhancements:
- A spam trap facility has been added, so form submissions that are obviously spam can be dismissed immediately.

Sporkie is a challenge/response spam email filter. Sporkie project uses CAPTCHAs (randomly generated, distorted images of numbers) in order to verify that a person sending email is human.

It works in the same manner as the ASK project, except that Sporkie uses CAPTCHAs. The main advantage to using CAPTCHAs is that it catches automated spam bots that dont spoof their email address. With ASK, such bots would get through the system.

This software works by sending a verifcation e-mail with a link back to anyone who sends you an e-mail. The user must then follow the link and enter the numbers they see in an image. If they input the correct numbers their e-mail gets put on a white list. All past (e-mail sent within the past 90 days) and future e-mails from that user will go directly to the intended account. It will completely eliminate all spam since it verifies that the e-mail address the mail was sent from was the real address, and that a human person uses that e-mail address. Other systems simply verify the address is a real e-mail address.

Sporkie is written completly in Java. It requires Java 5.0 or higher, however very minimal portions of code use 1.5 specific idioms. It would not be hard to write a Java 1.4 port.

Sporkie is provided under the OSCL Type-C license.

Sporkie is currently in an alpha stage so there is no stable release as of yet.

wpoison.php is a script that generates page after page of random fake email addresses, and is intended to be used for poisoning spambot email address databases.

wpoison.php is based on verion 1.8p of his script. It is a direct port and functionally equivalent. The reason for this port is that quite a few people do not have the ability to use CGI scripts on their sites. [cCOPYRIGHT=1]

All that is required to run wpoison.php is a web server configured for PHP and some form of a words file. You may download the words file that Ronald makes available on his site below along with the script.

Wpoison helps to combat the junk e-mail problem by effectively thwarting the efforts of junk e-mailers who regularly scan web pages, looking for target e-mail addresses to harvest. (The junk e-mailers subsequently send junk e-mail to all of the e-mail addresses that they harvest from various web sites.)

The idea behind Wpoison is really very simple. Junk e-mailers write programs to automatically scan thousands and thousands of web pages, looking for e-mail addresses which they then send unsolicited junk e-mail to, or which they sell to other spammers. By and large, these address harvesting web crawlers are about as intelligent as the spammers who use and/or develop them, which is to say not very. The majority of these programs can be easily fooled into accepting lots and lots of completely fake and useless e-mail addresses, so long as the bogus addresses in question appear to reside on ordinary nondescript web pages. That is where Wpoison comes in.

Wpoison is what is called a web CGI program. A CGI program is just like any other program, except that its purpose is to generate web pages on the fly and with dynamic content that can be different each time the program runs, which is to say each time the URL where the program is installed is referenced, either by someones web browser, or else by some web-scanning robotic program.

In the case of the Wpoison CGI program, the dynamic content that is generated each time the program is ``visited (by a web browser, or by a web-scanning robot program) is just a list of randomized bogus e-mail addresses, together with a list of randomized web hyper-links.

Now heres the catch... and this is the clever part. Each of the randomized web hyper-links that Wpoison generates looks exactly like an ordinary web hyper-link that leads off to someplace else, i.e. to some different web page having a different web URL. But in fact, that is just a matter of appearances, and the reality is that if you follow any one of these hyper-links, you will actually end up coming right back and executing the Wpoison CGI program again, at which point you will get yet another randomized dynamically generated web page, and that new page will contain its own totally new set of bogus E-mail addresses and also a fresh new set of randomized hyper-links. And of course, each of those new hyper-links will, if followed, lead right back to the Wpoison CGI program yet again, thus starting the whole cycle all over again.

It is important to note that when Wpoison is generating its randomized bogus e-mail addresses (and also its randomized pseudo-hyper-links) it uses an algorithm which makes the total number of different bogus e-mail addresses and pseudo-hyper-links essentially unlimited. In effect, Wpoison is capable of generating an infinite number of different bogus E-mail addresses!

So the basic idea behind Wpoison is to trap unwary and badly engineered address harvesting web crawlers, and to fool them into adding enormous quantities of completely bogus e-mail addresses to the E-mail address data bases of the spammers, thus polluting those data bases so badly that they become essentially useless, thereby putting the spammers who are using them out of business, or at least shutting them down for a time and causing them some major headaches while they try to clean up the messes in their now-heavily-polluted e-mail address data bases.

Khalkhi framework was formerly known as Contacts framework.
Khalkhi (say [?al?i]) is a plugin-based framework for (the properties of) entries in the KDE Addressbook and services upon them. It consists of two libs, libkhalkhicore and libkhalkhigui, and a control center module.
The framework models an addressbook entry, like a person or organization, as a list of property types, with no, one or more items of a type for each entry. There are three types of services for a property (e.g. email address):
- action service (e.g. send email)
- data action service (e.g. send file per email, like from dragndrop)
- status service (e.g. number of unread emails in assigned folder)
The tarball includes a lot of services for the most common properties:
- birthday: copy date; has birthday
- im address: chat with; send message; send file; online status
- email address: send email; copy address; send files/urls;
open assigned folders in KMail; unread emails in assigned KMail folder
- homepage: open; copy url;
- blog feed url: copy
- phone number: make call; send fax; send SMS; copy number;
- postal address: open in Google Maps; copy address
- note: copy note
Examples for programs using the framework are a cards server and a Kicker applet, which are available as seperate packages:
