Spamcalc takes a hostname or a list of hostnames and determines a dns spam score for each hostname. This value is an indication for the spam-ness of the hostname. The higher the score, the higher the chance that the hostname is actually a dns spam hostname. Hostnames that are considered dns spam are hostnames with (a part of) a sentence in them (master.of.the.world.net), swearwords (shittywhore.armaster.roadkill.net) and other forms of unwanted textual data (666666666666666666666666666666666.sixtysix.org, 0-1-2-3-4-5.blah.com).

Spamcup is a tool for automatic spam reporting via Spamcop.net. It performs the same actions as if you were to report spam to spamcop.net with a Web browser, but from the commandline. Spamcup is written in Perl.

The dnsreflector daemon listens for DNS queries on a local UDP port and answers with records pointing back to localhost. Combined with packet filter pf(4) this works as a bandwidth efficient spamtrap.

This plugin reports spam to various places.

IMAP Spam Begone (isbg) is a script that makes it easy to scan an IMAP inbox for spam using SpamAssassin and get your spam moved to another folder. Unlike the normal mode of deployments for SpamAssassin, isbg does not need to be involved in mail delivery, and can run on completely different machines to where your mailbox actually is.

Hex-a-hop is a puzzle game based on hexagonal tiles. There is no time limit and no real-time elements. The objective is simply to destroy all the green hexagonal tiles on each of the 100 levels. As you progress through the game, more types of tiles are introduced which make things more difficult and interesting (hopefully).

E-MailRelay is a simple SMTP proxy and store-and-forward message transfer agent (MTA). When running as a proxy all e-mail messages can be passed through a user-defined program, such as a spam filter, which can drop, re- address or edit messages as they pass through. When running as a store- and-forward MTA incoming messages are stored in a local spool directory, and then forwarded to the next SMTP server on request. E-MailRelay can also run as a POP3 server. Messages received over SMTP can be automatically dropped into several independent POP3 mailboxes.
