qmail-spp provides plug-in support for the qmail
SMTP daemon (qmail-smtpd). It allows you to write
external programs and use them to check SMTP
command argument validity. The plug-in can trigger
several actions, like denying a command with an
error message, logging data, adding a header, and
much more.

The Anomy mail sanitizer is a filter designed to block email-based security risks, such as trojans and viruses. It can scan an arbitrarily complex RFC822 or MIME message and remove or rename attachments, truncate unusually long MIME header fields and sanitize HTML by disabling Javascript, etc. It uses a single-pass pure Perl MIME parser, which can make it both more efficient and more precise than other similar programs. The sanitizer has built-in support for third-party virus scanners.

AMaViS-ng is a modular rewrite of amavisd and
amavis-perl. It scans email for malicious code
inside attachments and archive files, stopping
delivery if malicious code is found. It supports
integration of several third-party virus scanners
and integrates nicely into several MTA setups.
Unlike amavis-perl and amavisd, there is no need
for build-time configuration.

smtp-vilter is a high-performance content filter for sendmail, which detects email viruses and spam. It can pass, discard, or simply mark an email based on the results of a content scan. It relies on third-party products for the actual content scan. It uses the milter API to communicate with sendmail, and backends to communicate with the actual scanning engines. The backends can be chained to perform a series of checks on each message in one run.

Minimac is a minimalist, general purpose text macro processor. Its simplicity should make it particularly well suited as a front end preprocessor for little language compilers. It is meant to be simpler to use than m4. It uses an explicit argument stack, and user functions are defined by concatenation (similar to the Forth language). Macro expansion is delayed to the last possible moment. The software is currently in alpha release.

Mailfilter is a flexible utility to get rid of unwanted spam mails, before having to go through the trouble of downloading them into the local computer. It offers support for one or many POP accounts and is especially useful for dialup connections via modem. You can define your own filters (rules) to determine which e-mails should be delivered and which are considered waste.

Qmail-Scanner, (also known as scan4virus) is an addon that enables a Qmail Email server to scan all gatewayed Email for certain characteristics. It is typically used for its anti-virus protection functions, in which case it is used in conjunction with commercial virus scanners. but also enables a site to react to Email (at a server/site level) that contains specific strings in particular headers, or particular attachment filenames or types (e.g. *.VBS attachments). It also can be used as an archiving tool for auditing or backup purposes. Qmail-Scanner is integrated into the mail server at a lower level than some other Unix-based virus scanners, resulting in better performance. It is capable of scanning not only locally sent/received Email, but also Email that crosses the server in a relay capacity. It also has SpamAssassin support.

hd2u is Hany's Dos2Unix convertor, a filter used
to convert plain text from the DOS format (CR/LF)
to the UNIX format (LF) and vice versa. It can
also handle files in the Macintosh format (CR) and
convert them into other formats.

JHighlight is an embeddable Java syntax
highlighting library that supports Java, Groovy, C++, HTML,
XHTML, XML, and LZX languages and outputs to
XHTML. The library can be used in several ways:
embedded into another tool (for instance a blog
or forum), through the command-line to generate
highlighted files locally, or as a servlet filter
to highlight source files on your server on-the-
fly. It also supports RIFE templates tags and
highlights them clearly so that you can easily
identify the difference between your RIFE markup
and the actual marked up source.

acoc is a regular-expression based colour formatter for programs that display output on the command-line. It works as a wrapper around the target program, executing it and capturing the stdout stream. Optionally, stderr can be redirected to stdout, so that it, too, can be manipulated. acoc then applies matching rules to patterns in the output and applies colours to those matches.

HTML Purifier is PHP software for HTML filtering. It is an alternative to BBCode or other obscure custom markup languages. It will not only remove all malicious code (XSS), but will also make sure the HTML is standards compliant.

fdm (fetch and deliver mail) is a simple, lightweight replacement for mail fetching, filtering, and delivery programs such as fetchmail and procmail. It can fetch using POP3, POP3S, IMAP, IMAPS, or stdin, and deliver to a pipe, file, maildir, mbox, or SMTP server, based on a set of regexps. It can be used for both single user and multiuser setups, and is designed with privilege separation when running as root.

LEPL is a recursive descent parser library written
in Python. It is based on parser combinator
libraries popular in functional programming, but
also exploits Python language features. Operators
provide a friendly syntax, and the consistent use
of generators supports full backtracking and
resource management. Backtracking implies that a
wide variety of grammars are supported; appropriate memoisation ensures that even left-recursive grammars terminate.
