Bogofilter is a mail filter that classifies e-mail as spam or ham (non-spam) by a statistical analysis of the message's header and content (body). Email filtering is the processing of E-mail to organize it according to specified criteria Electronic mail, often abbreviated to e-mail, email, or originally eMail, is a Store-and-forward method of writing sending receiving Spamming is the abuse of electronic messaging systems to indiscriminately send unsolicited bulk messages Statistics is a mathematical science pertaining to the collection analysis interpretation or explanation and presentation of Data. The program is able to learn from the user's classifications and corrections. It was originally written by Eric S. Raymond, and is now maintained together with a group of contributors by David Relson, Matthias Andree and Greg Louis. Eric Steven Raymond (born December 4 1957 often referred to as ESR, is a Computer programmer, author and Open source software advocate
The statistical technique used is known as Bayesian filtering and its use for spam was first described by Paul Graham in his article A Plan For Spam. Bayesian spam filtering (pronounced BAYS-ee-ən IPA pronunciation:, after Rev Paul Graham (born 1964 is a Programmer, Venture capitalist and Essayist, known for his work on Lisp. Gary Robinson, in his weblog Rants, suggests some refinements for improved discrimination between spam and ham. Statistical discrimination is an Economic theory of Inequality based on group Stereotypes. Bogofilter's primary algorithm uses the f(w) parameter and the Fisher inverse chi-square technique that he describes.
Bogofilter is run by an MDA script to classify an incoming message as spam or ham (using wordlists stored by BerkeleyDB, SQLite3 or QDBM). A Mail Delivery Agent ( MDA) is Software that delivers E-mail messages right after they've been accepted on a server distributing them to recipients' individual "Scripting" redirects here For other uses see Script. Berkeley DB (BDB is a Computer software library that provides a high-performance embedded Database, with bindings in C, SQLite is a mostly ACID -compliant Relational database management system contained in a relatively small (~500 kB) C programming library Bogofilter provides processing for plain text and HTML. HTML, an initialism of HyperText Markup Language, is the predominant Markup language for Web pages It provides a means to describe the structure It supports multi-part MIME message with decoding of base64, quoted-printable, and uuencoded text and ignores attachments, such as images. Multipurpose Internet Mail Extensions ( MIME) is an Internet standard that extends the format of e-mail to support text in Character
Standard tests at TREC 2005 show that Bogofilter compares well to its competitors spambayes, CRM114 and DSPAM. SpamBayes is a Bayesian spam filter written in Python which uses techniques laid out by Paul Graham in his essay "A Plan for Spam" CRM114 (full name "The CRM114 Discriminator" is a program based upon a statistical approach for classifying data and especially used for filtering email spam. DSPAM is a Free software statistical Spam filter written by Jonathan A Other competitors include, but are not limited to Spamprobe and QSF.
