mimetic is a MIME library written in C++ designed to be easy to use and integrate but yet fast and efficient. It's standard compliant using the Standard Template Library for base C++ structures and supporting all relevant messaging RFCs. A powerful template encoding/decoding engine is also included to allow seamless extendibility (i.e. encryption codecs) and intuitive codec chains creation (using well-known Unix-style pipes syntax: a|b|c). Real world examples, documentation, and regression tests are included.
The Multivalent PDF Tools is a suite of tools for manipulating PDF documents. It includes tools for compressing, uncompressing (for hand editing), obtaining metadata, splitting and merging, encrypting and decrypting, validating, imposition (aka n-up), making page images, extracting text, and full-text indexing (with Lucene). The compress tool shrinks the PDF 1.5 Reference from 13.5MB to 8MB in PDF 1.5/Acrobat 6 format and down to 5.1MB in a new proposed "Compact" format.
Test::Parser is a collection of parsers for different test output file formats. These parse the data into a general purpose data structure that can then be used to create reports, do post-processing analysis, etc. It can also export tests in SpikeSource's TRPI test description XML language.
deplate converts wiki-like markup to LaTeX (standard classes, koma, dramatist, sweave), HTML/PHP (single page, chunked/website, HTML, or s5-based slideshow), DocBook (article, book, man/ref page), and really plain text. Currently supported input formats are viki and Ruby's rdoc. The viki markup supports footnotes, citations, index, table of contents, embedded LaTeX for mathematics, integration with R for dynamically generated figures and tables, and more. Output can be customized via page templates.
MailScanner is an email virus scanner, vulnerability protector, and spam tagger. It supports the Postfix, Sendmail, Exim, Qmail, and ZMailer MTAs, and the Sophos, McAfee, F-Prot, F-Secure, CommandAV, InoculateIT, Inoculan, eTrust, Kaspersky, Nod32, AntiVir, BitDefender, RAV, Panda, DrWeb, ClamAV, and other anti-virus scanners. It uses SpamAssassin for highly successful spam identification, and is designed to handle denial of service attacks. It will detect password-protected zip files and apply filename checking to their contents. It is very easy to install, requires no changes at all to your sendmail.cf file, is designed to be lightweight, and won't grind your mail system to a halt with its load. It can be integrated into any email system, regardless of the software in use.
GLD-fork is a fork of the GLD program by Salim Gasmi. The fork has been made because the original project has been dead for many years, and some new featured were needed. GLD-fork, as with the original GLD, adds greylisting functionality to the Postfix mail server. Greylisting is a fairly resource friendly anti-spam technique. GLD-fork can easily be combined with other (more resource consuming) tools to build anti-spam protection.
