	SpamAssassin - Wikipedia, the free encyclopedia
		SpamAssassin is generally regarded as one of the most effective spam filters, especially when used in combination with spam databases.
		SpamAssassin was created by Justin Mason who had maintained a number of patches against an earlier program named filter.plx by Mark Jeftovic, which in turn was begun in August 1997.
		In the default configuration, the content of the mail is appended as a MIME attachment, with a brief excerpt in the message body, and a description of the tests which resulted in the mail being classified as spam.

	SpamAssassin FAQ (Site not responding. Last check: 2007-11-07)
		SpamAssassin will NOT (by default) delete or move any email messages, but instead insert certain identifiers in the message header, thus allowing the user to filter the message using their email clients or promail.
		SpamAssassin inspects the headers and body of an email message and determines the probability of that message being spam.
		SpamAssassin is designed to provide an automated method of spam identification while allowing the individual to control the messages classified as spam.

	Stamp out spam with SpamAssassin (Site not responding. Last check: 2007-11-07)
		SpamAssassin, a relative newcomer to the fight against spam, was first released around April of 2001 by Matt Sergeant, Craig Hughes, and Justin Mason, and is currently (as of this writing) at version 2.41.
		SpamAssassin can easily be used with Procmail to filter spam on behalf of a single user, and it can be used with Sendmail or other MTAs to filter spam on behalf of an entire site.
		SpamAssassin is a score-based filter, which means that after applying all of its rules to a message, it comes up with a score that (hopefully) represents the likelihood that a message is spam.

	perl.com: Stopping Spam with SpamAssassin
		SpamAssassin is extremely configurable; you can select which rules you want to use, change the way the rules contribute to a piece of mail's "spam score," and add your own rules.
		SpamAssassin uses a variety of ways for testing whether an e-mail is spam, ranging from simple textual checks on the headers or body and detecting missing or misleading headers to network-based checks such as relay flhole lists and an interesting distributed system called
		Since SpamAssassin is provided as a command line tool as well as a set of Perl modules, it's easy enough to integrate it in whatever mail filtering solution you use.

	Mail::SpamAssassin::Conf - SpamAssassin configuration file (Site not responding. Last check: 2007-11-07)
		SpamAssassin is configured using some traditional UNIX-style configuration files, loaded from the /usr/share/spamassassin and /etc/mail/spamassassin directories.
		SpamAssassin includes a default set of 13 servers, among which 3 are picked randomly.
		Note: SpamAssassin requires at least 3 points from the header, and 3 points from the body to auto-learn as spam.

	ISG.EE How to block SPAM with SpamAssassin
		SpamAssassin looks at every incoming e-mail and assigns "SPAM-points" according to many different rules about what SPAM mails contain.
		My personal experience with SpamAssassin is that it works remarkably well, it marks about 95% of SPAM that I get as SPAM and it happens very rarely that a mail that is not SPAM gets marked as one.
		SpamAssassin is meant to be run using procmail.

	Spamassassin \| Bryn Mawr Computing
		Spamassassin is a program that scans incoming e-mail messages for signs that they might be spam.
		Spamassassin uses a complicated set of rules to determine whether a message appears to be spam.
		Some of the things which may cause a message to be flagged as spam include lines in all capital letters, multiple large images in the body of the message, frequent text color changes, certain phrases which are commonly found in marketing messages, and malformed delivery headers in the message.

	sa-learn - train SpamAssassin's Bayesian classifier (Site not responding. Last check: 2007-11-07)
		SpamAssassin does not support this method, due to experimental results which strongly indicate that it does not work well, and since Bayes is only one part of the resulting score presented to the user (while Bayes may have made the wrong decision about a mail, it may have been overridden by another system).
		The database of tokens, containing the tokens learnt, their count of occurrences in ham and spam, and the message count of the last message they were seen in.
		This is used so that SpamAssassin can avoid re-learning a message it's already seen, and so it can reverse the training if you later decide that message was previously learnt incorrectly.

	Spamotomy: Tools Search (Site not responding. Last check: 2007-11-07)
		An open source project, SpamAssassin has matured quickly in the past two years thanks to the help of patches sent in from dozens of contributors.
		We started by lowering the score threshold to 4.5, which means SpamAssassin needs fewer reasons to mark messages as spam (like when it detects SHOUTING in the subject and "unsubscribe" links in the body).
		All in all, SpamAssassin 2.55 is one of the most advanced anti-spam tools out there, and we recommend it to anyone who gets their email through a Unix-based server.

	Panix Help System - SpamAssassin
		Because SpamAssassin is third-party software, upgrades may result in changes in the point value of any of the rules.
		You might think that SpamAssassin would also be good for fllisting spammers' addresses, but this is not the case.
		When you call SpamAssassin from Procmail, you can set up a "user_prefs" file to change the point-value threshold for spam, specify whitelists and fllists, and assign custom values to particular "hit types".

	Setting up Spam Filtering with SpamAssassin (Site not responding. Last check: 2007-11-07)
		SpamAssassin itself does not delete email; all it does is perform certain tests on email messages that are passed through the program, and based on the outcome of such tests, assign a numerical score ("hits") to the message.
		SpamAssassin also has a fllist feature that allows one to list email addresses to be "fllisted" so that all email from these addresses is treated as spam and redirected to the spam folder.
		A handful of messages tagged as spam by SpamAssassin were of the borderline variety: messages that are unsolicited and mass-mailed to a (usually) limited number of addresses, but with legitimate content that may be of interest to a substantial number of addressees.

	Spamassassin Intro, Setup, and Advanced Techniques
		And for the times when Spamassassin just doesn't know you want commercial mail from a given vendor, you can manually say "I want all mail from someone@company.com or *@company.com" and they'll arrive at your mailbox even if the spam score is very high.
		I've spent quite a bit of time teaching my spamassassin installation about known spam and ham, so I feel comfortable making the second cutoff at 8.0 (spams with a score higher than this I won't look at at all, but they're still available if I later find out that something was misclassified).
		Because the isbg script and spamassassin can run on a machine other than the mailserver, this approach can be used to filter mail on a remote IMAP mailserver that may not be able to run Spamassassin directly.

	Using SpamAssassin with Ximian Evolution
		Best of all, SpamAssassin accesses Razor by default if it is installed on the computer, so there is little extra configuration, razor.sourceforge.net.
		If you are running the “spamd” daemon from SpamAssassin, you can use “spamc” in the filter settings instead of “spamassassin.” This may speed things up slightly as it keeps from loading a new instance of Perl each time a message needs to be checked.
		SpamAssassin is available for download as source, from the Perl CPAN repository, and even from an RPM package provided by Red Hat.

	SpamAssassin FAQ (Sonic.net, Inc.)
		There are currently two choices available for enabling SpamAssassin, "SpamAssassin" and "SpamAssassin SQL." The newer "SpamAssassin SQL" is far more user-friendly, but you may prefer the increased granularity of control with the older, shell-based SpamAssassin tool.
		The preferences for SpamAssassin are contained in a text file located at /home/u/username/.spamassassin/user_prefs (where "username" is the Sonic.net account ID, and "u" is the first letter of that account ID).
		SpamAssassin's rules are largely English-language sensitive, so spam in other languages is more likely to slip through the cracks or be erroneously labelled as spam-like.

	Installing spam assassin
		Check to make sure new versions of spamd, spamc, spamassassin, and sa_learn were installed, and there are no old versions lying around.
		Make sure spamassassin is running as "nobody"; otherwise it will not work.
		In this situation, be sure to save the old files, because SpamAssassin sometimes appears to install when in fact it is not installing anything.

	Where's SpamAssassin? (Site not responding. Last check: 2007-11-07)
		SpamAssassin users routinely report 100% spam reduction and 0% false positives (although these self-reported statistics are probably biased), and are generally overjoyed with the results.
		By itself, SpamAssassin is little more than the software implementation of an interesting idea: apply statistics, neural networks and Bayesian probabilities to the problem of classifying mail as spam or not.
		SpamAssassin's Bayesian engine even redefines the meaning of spam by letting you say, "This is the mail I want," and "This mail I don't want." SpamAssassin also mixes other tools into its scoring system, such as DNS-based fllists and collaborative scoring, as well as more traditional keyword searches and formatting tests.
