DisSent (short for "Distribute Sent Mails") is a program for separating your sent mail from a single folder into different folders based on properties of the individual messages in the folder. It scans your mail storage and proposes a set of actions to tidy up your sent mail folders. More precisely, it gives you a list of messages along with proposals on where to move these messages. You can then select the messages you want to move and let DisSent do the actual work.
dkimproxy is an SMTP proxy that signs and/or verifies Domain Keys Identified Mail (DKIM). It is designed to work with Postfix. It comprises two separate proxies: an "outbound" proxy for signing outgoing email, and an "inbound" proxy for verifying signatures of incoming email. With Postfix, the proxies can operate as either Before-Queue or After-Queue content filters.
ffe is a flat file extractor. It can be used for reading different flat file structures and displaying them in different formats. ffe can read fixed length and separated text files and fixed length binary files. It is a command line tool developed under GNU/Linux. The main areas of use are extracting particular fields or records from a flat file, converting data from one format to an other, e.g. from CSV to fixed length, verifying a flat file structure, as a testing tool for flat file development, and displaying flat file content in human readable form.
PigeonDeliver is the delivery agent of the PigeonAir project, a solution to easily build up clustered, scalable, and modular email services. PigeonDeliver is modular in nature, allowing it to be used on Postfix and other MTAs using their own native APIs without performance loss. It allows mail services to be easily and transparently distributed among a cluster of mail server, easily supporting new services and new modules added using the PigeonDeliver API, which simplifies writing filters and/or delivery agents.
SeeYouLater's purpose is to fetch a list of IPs of known spammers and to ban them by putting them in /etc/hosts.deny. /etc/hosts.deny is usually read by xinetd or daemons using tcpwrapper. The software is composed of: the feeder, that looks at SMTP daemon logs for the string ++BAN:IP++ and feeds the database accordindly; and the butcher, that looks at the database and updates /etc/hosts.deny. You may want to run the butcher on a system that has no access to the SMTP logfiles, but you can install both packages on the same system. It has been written to run with Exim.
libmime is a MIME parser in the same vein as Expat, the stream-oriented XML parser. As input is fed to the parser, events are generated which an application can catch by registering event handlers. Such events include the Unix From_ line, start of entity, end of entity, entity boundary, header, end of headers, and body. libmime supports MIME message editing through a delta mechanism. Edit contexts are instantiated and changes applied to specific contexts. Edit contexts can then be expressed in standard unified diff format which, when applied to the input source stream, will result in the new message.
Pymadea (PYthon MAil DElivery Agent) is a simple replacement for procmail. Configuration files are ordinary Python scripts. Modules from the standard library are used where possible. It consists of a set of useful scripts that are helpful for using Python as an MDA, rather than a normal, standalone application.
mhrw is a commandline tool for manipulating mail headers. It can be useful in complex MTA setups. Header entries can be manipulated through regular expressions. Additionally, it can be used to add header entries. mhrw was written to get better performance than scripts using tools such as sed, awk, and tr. mhrw is able to pipe mail messages through external commands, depending on matching a regular expression.
Common Configuration Parser (CCP) is a program that reads configuration files and upgrades them. It takes an oldfile (typically the configuration file currently in use) and a newfile (typically the default new configuration file) and optionally a template (a file that describes how the generated configuration file should look) and merges the files into one, creating a new configuration file that has the changes made to the old file in addition to the new options included in the new file. It is completely independent of the program that created the configuration file, and can be used for many different purposes such as merging changes between an old user-edited configuration file and a .rpmnew file generated by RPM during upgrades.
