BlackMamba is a semi-automatic spam filter and email previewer. It lets you connect to your POP3 mail server and peek into your mailbox. BlackMamba automatically categorizes the messages as "friendly", "possible spam", and "spam" based on a few simple configuration steps. It allows you to delete the messages, and it maintains an address book, a list of spammers, and a mail size filter. It should be useful if you've gone on a holiday and haven't checked your email for weeks and know that your mailbox will be full of junk. BlackMamba sorts your email messages without downloading the messages in their entirety.
Bogofilter is a Bayesian spam filter. In its normal mode of operation, it takes an email message or other text on standard input, does a statistical check against lists of "good" and "bad" words, and returns a status code indicating whether or not the message is spam. Bogofilter is designed with fast algorithms (including Berkeley DB system), coded directly in C, and tuned for speed, so it can be used for production by sites that process a lot of mail.
DSBL Server Software
The DSBL server software allows any site to run their own DSBL-like service. This package provides the cookie server, mail processor, and several other miscellaneous utilies that make up existing DSBL services.
Scrubber is a server-side, high performance, extendable, SMTP-independent mail content filtering system. It supports global, per- domain, and per-user configurations with caching support. Any number of configuration storage mechanisms are supported through the plugin interface. It supports anti-virus scanning, whitelist/blacklist matching, Bayesian probability scoring, and attachment blocking. Clients exist for SMTP-level integration in the common client-server architecture. Additional clients can be created for any mailer on any platform.
smtp-vilter is a high-performance content filter for sendmail-based email servers. It is mainly meant for detecting viruses. It uses the milter API to connect to sendmail, and it can scan email messages using various backends.
Fix-mime-charset automatically detects character sets of email message and modifies the Content-Type header appropriately. It can be used as mail filter in mailing lists where users often set the charset of their messages incorrectly. It processes messages fast and accurately, ignoring attachments, and correctly interprets transfer-encodings. None but the Content- Type header is changed.
SpamAssassin is a mail filter that uses a wide range of heuristic tests on mail headers and body text to identify spam. Once identified, the mail can then be optionally tagged as spam for later filtering. It provides a command line tool to perform filtering, a client-server system to filter large volumes of mail, and Mail::SpamAssassin, and a set of Perl modules that implement a Mail::Audit plugin0 (allowing SpamAssassin to be used in a Mail::Audit filter, a spam-protection proxy POP/IMAP server, or almost anywhere).
CleanPOP logs into a POP3 server and deletes messages which have had a local (or remote) spam header added to them, as well as messages that have been on the server for longer than a user-configurable amount of time. It helps you keep your POP3 mailbox clean, so you can use Webmail or download messages from your POP3 server to other machines without having to deal with spam. It correlates messages from your local mbox file with messages on the POP3 server, which means that you can use local antispam solutions to clean your remote inbox, and it never deletes an unfetched message, unlike other mail expiration scripts.
CanIt is a server-based spam-control system built around SpamAssassin, MIMEDefang, Apache, and PostgreSQL. It features sophisticated spam-handling techniques which minimize the amount of spam you receive while guaranteeing that you'll never lose a valid email. CanIt achieves extraordinarily accurate discrimination through human intervention, and includes mechanisms to minimize the amount of human intervention required.
ripMIME extracts attachment files out of a MIME-encoded email pack.
