The SeaMonkey project is a community effort to develop an all-in-one Internet application suite. It contains an Internet browser, email and newsgroup client with an included Web feed reader, HTML editor, IRC chat, and Web development tools, and is sure to appeal to advanced users, Web developers, and corporate users. It uses much of the Mozilla source code powering such successful siblings as Firefox, Thunderbird, Camino, Sunbird, and Miro.
The AmavisNewSQL SquirrelMail plugin gives you per-user control of a subset of SpamAssassin settings which are stored in a database. It also allows you to use a quarantine database for questionable mail. This plugin was designed with enterprise use in mind, and differs from other plugins in that it works with amavis-new rather than SpamAssassin directly. Most of the code lives in an external class that you can reuse in your own admin tools. It even has support for SOAP calls to perform common tasks.
GroupServer is a Web-based mailing list manager designed for large sites. It provides email interaction like a traditional mailing list manager but also supports reading, searching, and posting of messages and files via the Web. Users have forum-style profiles, and can manage their email addresses and other settings using the same Web interface. It has supports features such as Atom feeds, a basic CMS, statistics, multiple verified addresses per user, and bounce detection, and is able to be heavily customized.
libSieve is an implementation of the Sieve mail sorting language originally developed for the Cyrus mail system. libSieve helps to bring mail sorting functionality into your mail server application without the need to reinvent the wheel. As a library, it is not intended for end users expecting a ready-to-run program.
DSPAM is a server-side statistical anti-spam agent for Unix email servers. It masquerades as the email server's local delivery agent and effectively filters spam using a combination of de-obfuscation techniques, specialized algorithms, and statistical analysis. The result is an administratively maintenance-free, self-learning anti-spam tool. DSPAM has yielded real-world success rates beyond 99.9% accuracy with less than a 0.01% chance of false positives.
cats2procmailrc is a filter to generate a .procmailrc file from a much terser and friendlier file consisting mostly of single-line rules. These suffice to do the most common mail filing, making maintenance of a procmailrc very easy for someone with more than a few filing rules. Each rule normally names the folder, an optional subject tag, and the pattern. Raw procmail rules may also be included for those rare complex filings.
Scriptid is a program and a library that can be used to determine whether a given text file contains code of a specified programming language. The current release can tell whether a file contains vbscript or not. It should be possible to extend this to any number of other languages. It is important to also download the latest neural network weights update file.
nmzmail is a tool to use the namzu2 search engine from within the Mutt email reader to search email stored in maildir folders. Based on the result of the namazu query, nmzmail generates a maildir folder containing symbolic links to the messages matching the query. A simple Mutt macro makes it easy to use from within Mutt.
