smf-grey is a Sendmail milter that implements the GreyList Anti SPAM technology.
This technology can significantly reduce the amount of SPAM and viruses going from zombie computers (infected Windows PC), which produce more than 80% of SPAM.
GreyList Sendmail milter has a very effective GreyList algorithm on the base of the tuple: sender IP address (C class subnet), sender envelope and recipient envelope.
Its very recommended to use the smf-grey milter combined with the smf-zombie and the smf-spf milters. Its a triple impact on SPAM and viruses, that will seriously increase the efficiency of filtration.
This milter aims to be lightweight, reliable and simple. Its written in C.
Main features:
- It has a hosts/networks whitelist;
- It has an autowhitelist;
- It can add the information header with GreyList results to scanned messages;
- It can log all milter activities through the syslog service.
Advantages:
- Small code;
- Fast work;
- Stability (production quality);
- Few system resources are required.
Enhancements:
- Whitelists auto reloading was implemented.
- Autowhitelisted records regular dumping and reloading was implemented.
- The default greylisting time period was increased.
- New TODO tasks were added.
- Cosmetic enhancements were made.

SQLgrey is a Postfix greylisting policy service with auto- whitelisting and an SQL database as storage backend.
The project is based on postgrey, refining auto-whitelisting and storing whitelists and connection attempts in a database. Its goal is reducing the amount of spam reaching user mailboxes.
Main features:
- SQLgrey can withstand a database crash (grey-listing is automatically switched off)
- 3 grey-listing algorithms to choose from
- Support for file-based IP and FQDN whitelists
- Support for fetching up-to-date whitelists from a repository
- Can mail the admin when the database is unavailable
- Auto-whitelists now understand SRS (SPF-aware mail forwarding)
- IPv6 support
- OPTIN / OPTOUT support
- Fine log controls
- Activity reports

Flate library is a template library used to deal with html code in CGI applications. The library includes C and Perl support. All html code is put in an external file (the template) and printed using the library functions: variables, zones (parts to be displayed or not) and tables (parts to be displayed 0 to n times).
Using this method you dont need to modify/recompile your application when modifying html code, printing order doesnt matter in your CGI code, and your CGI code is much cleaner.
Enhancements:
- can now include external files with #INCLUDEFILE /path/to/file.html

mod_filter allows you to filter output from other modules inside of Apache. This allows you to implement filters (think Swedish Chef, jive, etc.).

You can also use it to retailer output for your locale. This works with HTML documents, mod_perl, PHP, JServ, CGIs, and for that matter just about any sort of custom handler you might have.

As the name already suggests, ncdu is an NCurses version of the famous old du unix command.

NCurses Disk Usage provides a fast and easy interface to your harddrive. Where is your disk space going? Why is your home directory that large? ncdu can answer those questions for you in just a matter of seconds!

Geant4 project is a toolkit for the simulation of the passage of particles through matter.
Its application areas include high energy physics and nuclear experiments, medical, accelerator and space physics studies.
Enhancements:
- Major updates to models and model APIs, major updates to many examples, and numerous bugfixes.

Coherent Mail Gateway is intended to be a very easy to set up MTA using SMTP and POP3. Greylisting is used on the SMTP daemon to reduce spam.

In addition, quite a lot of checks on the validity of information from the SMTP client (such as claimed server name and sender) are carried out, and anyone caught telling lies is disconnected.

Grey-, black-, and white-listing are supported, as well as (optionally) ClamAV and Spamhaus. The target market is users with static IP addresses. Others can use the system, but its value will be limited to outgoing email.
