!UIUC

Mail::SpamAssassin::UIUC is a project to connecting the CITES Spam Control (CSC) project, which runs on all mails sent to @uiuc.edu addreses (plus internal CITES mail servers like express.cites.uiuc.edu), and SpamAssassin, which is used at many smaller sites for all incoming mail. The goals were to a) make sure that the work from CITES' servers is not removed by SpamAssassin and b) hopefully use the information received from those servers as well.

Mail::SpamAssassin::Plugin::iXhash

Mail::SpamAssassin::Plugin::iXhash is based on the procmail-based project 'NiXSpam', created and maintained by Bert Ungerer, editor with the German IT-magazin 'iX' (http://www.heise.de/ix/). Basically redundant information is removed from the body of a mail, then a MD5 hash is computed from the rest and compared to a given database of known spam. The actual comparison is realised via DNS. See code for more info. Read up at http://www.heise.de/ix/nixspam/ for even more.

No further development, usage discouraged. .

CustomDeleteTag

This SpamAssassin plugin module allows users to specify a value that will be added to the message header, for all messages, specifying what value/score it is safe to delete the message. Obviously, you need some other process that looks at this header and performs the action, since SpamAssassin only filters and does not delete.

Persistent Database Plugin

This plugin module provides persistent database connections. It uses the DBI interface in much the same way that Apache::DBI does, in fact a large portion of the inspiration comes from that module.

To use, all you need to do is load the plugin module, via loadplugin, and it will automatically step in and handle your database connections.

Requires SpamAssassin 3.1+

Checks for specific keywords in gif/jpg/png attachments, using gocr. This can be used to detect spam that puts all the real contect in an attached image, accompanied with random text and html (no URL's, etc). There are also various rules to validate attached images and detect forged content types or broken images. This plugin needs SpamAssassin 3.1.1 or later. The version 2.0 is able to defeat recent gif animations which use gif tricks to avoid OCR.

Addressbook

This provides a way to automatically give a negative score to all addresses in an addressbook, which may be updated dynamically. It's not the same as whitelisting all addresses because spammers may know about some of them, so we don't want to whitelist, only give a small negative score. It's not the same as autowhitelist (AWL), which is an unlabeled learner, i.e. it just smooths scores per sender over time, but doesn't help senders who have consistently high scores.

DKIM Reputation Plugin

Replacement of the DKIM.pm plugin with additional inclusion of reputation data from www.dkim-reputation.org. This aids especially to block known spam accounts at freemailers and spammers sending DKIM signed spam with their own domains. Additionally positive reputation will be used in the future to reduce the false positive problem (positive scoring can be disabled). Currently an appropriate ruleset to distinct between neutral and good reputation is elaborated, feedback is welcome.

Requires SpamAssassin 3.1.2+

Extractor plugins can extract parts that will be fed into the plugin for checking, so for example a an image OCR extractor could get to check images extracted from a PDF by another extractor. How to extract what from what is very configurable. Included are configs for MS Word, RTF, OpenDocument and PDF files, and a very simplistic OpenXML plugin.
