    'userprefs_filename'  => $ENV{HOME}.'/.spamassassin.cf'
  });
  my $mail = Mail::SpamAssassin::MyMailAudit->new();

    $mail->accept("caught_spam");
  }

DESCRIPTION

The Mail::SpamAssassin check() method returns an object of this class. This object encapsulates all the per-message state.


METHODS

$isspam = $status->is_spam ()
After a mail message has been checked, this method can be called. It will return 1 for mail determined likely to be spam, 0 if it does not seem spam-like.

$list = $status->get_names_of_tests_hit ()
After a mail message has been checked, this method can be called. It will return a comma-separated string, listing all the symbolic test names of the tests which were trigged by the mail.

$num = $status->get_hits ()
After a mail message has been checked, this method can be called. It will return the number of hits this message incurred.

$num = $status->get_required_hits ()
After a mail message has been checked, this method can be called. It will return the number of hits required for a mail to be considered spam.

$report = $status->get_report ()
Deliver a ``spam report'' on the checked mail message. This contains details of how many spam detection rules it triggered.

The report is returned as a multi-line string, with the lines separated by \n characters.

$status->rewrite_mail ()
Rewrite the mail message. This will add headers, and possibly body text, to reflect its spam or not-spam status.

The modifications made are as follows:

Subject: header for spam mails
The string *****SPAM***** is prepended to the subject, unless the rewrite_subject 0 configuration option is given.

X-Spam-Status: header for spam mails
A string, Yes, hits=nn required=nn tests=... is set in this header to reflect the filter status. The keys in this string are as follows:

X-Spam-Report: header for spam mails
The SpamAssassin report is added to the mail header if the report_header = 1 configuration option is given.
hits=nn The number of hits the message triggered.
required=nn The threshold at which a mail is marked as spam.
tests=... The symbolic names of tests which were triggered.
X-Spam-Flag: header for spam mails
Set to YES.

Content-Type: header for spam mails
Set to text/plain, in order to defang HTML mail or other active content that could ``call back'' to the spammer.

spam mail body text
The SpamAssassin report is added to top of the mail message body, unless the report_header 1 configuration option is given.

X-Spam-Status: header for non-spam mails
A string, No, hits=nn required=nn tests=... is set in this header to reflect the filter status. The keys in this string are the same as for spam mails (see above).

$messagestring = $status->get_full_message_as_text ()
Returns the mail message as a string, including headers and raw body text.

If the message has been rewritten using rewrite_mail(), these changes will be reflected in the string.

Note: this is simply a helper method which calls methods on the mail message object. It is provided because Mail::Audit uses an unusual (ie. not quite intuitive) interface to do this, and it has been a common stumbling block for authors of scripts which use SpamAssassin.

$status->handle_auto_report ()
If this mail message has a high enough hit score, report it to spam-tracking services straight away, without waiting for user confirmation. See the documentation for spamassassin's -r switch for details on what spam-tracking services are used.

$status->finish ()
Indicate that this $status object is finished with, and can be destroyed.

If you are using SpamAssassin in a persistent environment, or checking many mail messages from one the Mail::SpamAssassin manpage factory, this method should be called to ensure Perl's garbage collection will clean up old status objects.
