SYNOPSIS

  my $mail = Mail::Audit->new();

  my $spamtest = Mail::SpamAssassin->new();
  my $status = $spamtest->check ($mail);

  if ($status->is_spam ()) {

DESCRIPTION

Mail::SpamAssassin is a Mail::Audit plugin to identify spam using text analysis and several internet-based realtime blacklists.

Using its rule base, it uses a wide range of heuristic tests on mail headers and body text to identify "spam", also known as unsolicited commercial email.

Once identified, the mail can then be optionally tagged as spam for later filtering using the user's own mail user-agent application.

This module implements a Mail::Audit plugin, allowing SpamAssassin to be used in a Mail::Audit filter. If you wish to use a command-line filter tool, try the spamassassin tool provided.

SpamAssassin also includes support for reporting spam messages to collaborative filtering databases, such as Vipul's Razor ( http://razor.sourceforge.net/ ).

METHODS

$f = new Mail::SpamAssassin( [ { opt => val, ... } ] )

Constructs a new Mail::SpamAssassin object. You may pass the following attribute-value pairs to the constructor.

rules_filename

The filename to load spam-identifying rules from. (optional)

userprefs_filename

The filename to load preferences from. (optional)

config_text

The text of all rules and preferences. If you prefer not to load the rules from files, read them in yourself and set this instead.

If none of rules_filename, userprefs_filename, or config_text is set, the Mail::SpamAssassin module will search for the configuration files in the usual installed locations.

local_tests_only

If set to 1, no tests that require internet access will be performed.

$status = $f->check ($mail)

Check a mail, encapsulated in a Mail::Audit object, to determine if it is spam or not.

Returns a Mail::SpamAssassin::PerMsgStatus object which can be used to test or manipulate the mail message.

Note that the Mail::SpamAssassin object can be re-used for further messages without affecting this check; in OO terminology, the Mail::SpamAssassin object is a "factory".

$f->report_as_spam ($mail)

Report a mail, encapsulated in a Mail::Audit object, as human-verified spam. This will submit the mail message to live, collaborative, spam-blocker databases, allowing other users to block this message.

$f->reply_with_warning ($mail, $replysender)

Reply to the sender of a mail, encapsulated in a Mail::Audit object, explaining that their message has been added to spam-tracking databases and deleted. To be used in conjunction with report_as_spam. The $replysender argument should contain an email address to use as the sender of the reply message.

$text = $f->remove_spamassassin_markup ($mail)

Returns the text of the message, with any SpamAssassin-added text (such as the report, or X-Spam-Status headers) stripped.
