PROGRAM:
NAME
spamassassin - extensible email filter used to identify spam
DESCRIPTION
SpamAssassin is an intelligent email filter which uses a diverse range of tests to
identify unsolicited bulk email, more commonly known as "spam". These tests are applied
to email headers and content to classify email using advanced statistical methods. In
addition, SpamAssassin has a modular architecture that allows other technologies to be
quickly wielded against spam and is designed for easy integration into virtually any email
system.
SYNOPSIS
For ease of access, the SpamAssassin manual has been split up into several sections. If
you're intending to read these straight through for the first time, the suggested order
will tend to reduce the number of forward references.
Extensive additional documentation for SpamAssassin is available, primarily on the
SpamAssassin web site and wiki.
You should be able to view SpamAssassin's documentation with your man(1) program or
perldoc(1).

CONFIGURATION FILES
The SpamAssassin rule base, text templates, and rule description text are loaded from
configuration files.
Default configuration data is loaded from the first existing directory in:
/var/lib/spamassassin/3.004001
/usr/share/spamassassin
/usr/share/spamassassin
/usr/local/share/spamassassin
/usr/share/spamassassin
Site-specific configuration data is used to override any values which had already been
set. This is loaded from the first existing directory in:
/etc/spamassassin
/usr/etc/mail/spamassassin
/usr/etc/spamassassin
/usr/local/etc/spamassassin
/usr/pkg/etc/spamassassin
/usr/etc/spamassassin
/etc/mail/spamassassin
/etc/spamassassin
From those three directories, SpamAssassin will first read files ending in ".pre" in
lexical order and then it will read files ending in ".cf" in lexical order (most files
begin with two numbers to make the sorting order obvious).
In other words, it will read init.pre first, then 10_default_prefs.cf before 50_scores.cf
and 20_body_tests.cf before 20_head_tests.cf. Options in later files will override
earlier files.
Individual user preferences are loaded from the location specified on the "spamassassin",
"sa-learn", or "spamd" command line (see respective manual page for details). If the
location is not specified, ~/.spamassassin/user_prefs is used if it exists. SpamAssassin
will create that file if it does not already exist, using user_prefs.template as a
template. That file will be looked for in:
/etc/spamassassin
/usr/etc/mail/spamassassin
/usr/share/spamassassin
/etc/spamassassin
/etc/mail/spamassassin
/usr/local/share/spamassassin
/usr/share/spamassassin
TAGGING
The following two sections detail the default tagging and markup that takes place for
messages when running "spamassassin" or "spamc" with "spamd" in the default configuration.
Note: before header modification and addition, all headers beginning with "X-Spam-" are
removed to prevent spammer mischief and also to avoid potential problems caused by prior
invocations of SpamAssassin.
TAGGING FOR SPAM MAILS
By default, all messages with a calculated score of 5.0 or higher are tagged as spam.
If an incoming message is tagged as spam, instead of modifying the original message,
SpamAssassin will create a new report message and attach the original message as a
message/rfc822 MIME part (ensuring the original message is completely preserved and easier
to recover).
The new report message inherits the following headers (if they are present) from the
original spam message:
From: header
To: header
Cc: header
Subject: header
Date: header
Message-ID: header
The above headers can be modified if the relevant "rewrite_header" option is given (see
"Mail::SpamAssassin::Conf" for more information).
By default these message headers are added to spam:
X-Spam-Flag: header
Set to "YES".
The headers that added are fully configurable via the "add_header" option (see
"Mail::SpamAssassin::Conf" for more information).
spam mail body text
The SpamAssassin report is added to top of the mail message body, if the message is
marked as spam.
DEFAULT TAGGING FOR ALL MAILS
These headers are added to all messages, both spam and ham (non-spam).
X-Spam-Checker-Version: header
The version and subversion of SpamAssassin and the host where SpamAssassin was run.
X-Spam-Level: header
A series of "*" charactes where each one represents a full score point.
X-Spam-Status: header
A string, "(Yes|No), score=nn required=nn tests=xxx,xxx
autolearn=(ham|spam|no|unavailable|failed)" is set in this header to reflect the
filter status. For the first word, "Yes" means spam and "No" means ham (non-spam).
The headers that added are fully configurable via the "add_header" option (see
"Mail::SpamAssassin::Conf" for more information).
INSTALLATION
The spamassassin command is part of the Mail::SpamAssassin Perl module. Install this as a
normal Perl module, using "perl -MCPAN -e shell", or by hand.
Note that it is not possible to use the "PERL5LIB" environment variable to affect where
SpamAssassin finds its perl modules, due to limitations imposed by perl's "taint" security
checks.
For further details on how to install, please read the "INSTALL" file from the
SpamAssassin distribution.
