[More] the message is spam.

The Apache Java Enterprise Mail Server (a.k.a. Apache James) is a 100% pure Java SMTP and POP3 Mail server and NNTP News server. James is a complete and portable enterprise mail engine solution based on currently available open protocols. James is ... [More] also a mail application platform. We have developed a Java API to let you write Java code to process emails that we call the mailet API. A mailet can generate an automatic reply, update a database, prevent spam, build a message archive, or whatever you can imagine. A matcher determines whether your mailet should process an email in the server. The James project hosts the Mailet API, and James provides an implementation of this mail application platform API.

Are you tired of the constant bombardment of your inbox by unwanted email pushing everything from porn to get rich quick schemes? Have you tried other spam filters but become disenchanted with them when you realized that their manually generated rule ... [More] sets weren't updated fast enough to keep up with spammers wording changes? Or that they generated unwanted false positive scores? SpamProbe operates on a different basis entirely. Instead of using pattern matching and a set of human generated rules SpamProbe relies on a Bayesian analysis of the frequency of words used in spam and non-spam emails received by an individual person. The process is completely automatic and tailors itself to the kinds of emails that each person receives. [Less]

The main idea behind was in situation where you have SpamAssassin installed on the mail server itself and there's no use to have another spam procesing engine. For instance I have SA installed on my home mailserver and I have the office email ... [More] account (no SA at office) and I would like to use my home SA to identify junk. On my office account I have Report as Spam (Rspam) Plugin installed so I didn't touch learn/report stuff. Of course spamc is still required (it usualy comes already installed in most modern distros). If this makes sense I'll add port option, ssl, and username option. [Less]

Mailvisa is a spam filter along the lines of Paul Graham's "A Plan for Spam". It classifies messages by comparing the words in them to known spam words. CPU usage, filtering speed, and filtering accuracy are comparable to other Bayesian filters. ... [More] Mailvisa was originally intended as a platform for experimentation with different filtering parameters, but it has evolved into a useful spam classifier. [Less]
