NAME
       Mail::SpamAssassin::PerMsgStatus - per-message status (spam or
       not-spam)
SYNOPSIS
         my $spamtest = new Mail::SpamAssassin ({
           'rules_filename'      => '/etc/spamassassin.rules',
           'userprefs_filename'  => $ENV{HOME}.'/.spamassassin/user_prefs'
         });
         my $mail = $spamtest->parse();
         my $status = $spamtest->check ($mail);
         my $rewritten_mail;
         if ($status->is_spam()) {
           $rewritten_mail = $status->rewrite_mail ();
         }
         ...
DESCRIPTION
       The Mail::SpamAssassin "check()" method returns an object of this
       class.  This object encapsulates all the per-message state.
METHODS
       $status->check ()
           Runs the SpamAssassin rules against the message pointed to by the
           object.
       $status->learn()
           After a mail message has been checked, this method can be called.
           If the score is outside a certain range around the threshold, ie.
           if the message is judged more-or-less definitely spam or definitely
           non-spam, it will be fed into SpamAssassin's learning systems
           (currently the naive Bayesian classifier), so that future similar
           mails will be caught.
       $score = $status->get_autolearn_points()
           Return the message's score as computed for auto-learning.  Certain
           tests are ignored:
             - rules with tflags set to 'learn' (the Bayesian rules)
             - rules with tflags set to 'userconf' (user white/black-listing rules, etc)
             - rules with tflags set to 'noautolearn'
           Also note that auto-learning occurs using scores from either
           scoreset 0 or 1, depending on what scoreset is used during message
           check.  It is likely that the message check and auto-learn scores
           will be different.
       $score = $status->get_head_only_points()
           Return the message's score as computed for auto-learning, ignoring
           all rules except for header-based ones.
       $score = $status->get_learned_points()
           Return the message's score as computed for auto-learning, ignoring
           all rules except for learning-based ones.
       $score = $status->get_body_only_points()
           Return the message's score as computed for auto-learning, ignoring
           all rules except for body-based ones.
       $score = $status->get_autolearn_force_status()
           Return whether a message's score included any rules that are
           flagged as autolearn_force.
       $rule_names = $status->get_autolearn_force_names()
           Return a list of comma separated list of rule names if a message's
           score included any rules that are flagged as autolearn_force.
       $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.
       $list = $status->get_names_of_subtests_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 meta-rule sub-tests which were trigged by the
           mail.  Sub-tests are the normally-hidden rules, which score 0 and
           have names beginning with two underscores, used in meta rules.
       $num = $status->get_score ()
           After a mail message has been checked, this method can be called.
           It will return the message's score.
       $num = $status->get_required_score ()
           After a mail message has been checked, this method can be called.
           It will return the score required for a mail to be considered spam.
       $num = $status->get_autolearn_status ()
           After a mail message has been checked, this method can be called.
           It will return one of the following strings depending on whether
           the mail was auto-learned or not: "ham", "no", "spam", "disabled",
           "failed", "unavailable".
           It also returns is flagged with auto_learn_force, it will also
           include the status and the rules hit.  For example:
           "autolearn_force=yes (AUTOLEARNTEST_BODY)"
       $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.
       $preview = $status->get_content_preview ()
           Give a "preview" of the content.
           This is returned as a multi-line string, with the lines separated
           by "\n" characters, containing a fully-decoded, safe, plain-text
           sample of the first few lines of the message body.
       $msg = $status->get_message()
           Return the object representing the message being scanned.
       $status->rewrite_mail ()
           Rewrite the mail message.  This will at minimum add headers, and at
           maximum MIME-encapsulate the message text, to reflect its spam or
           not-spam status.  The function will return a scalar of the
           rewritten message.
           The actual modifications depend on the configuration (see
           "Mail::SpamAssassin::Conf" for more information).
           The possible modifications are as follows:
           To:, From: and Subject: modification on spam mails
               Depending on the configuration, the To: and From: lines can
               have a user-defined RFC 2822 comment appended for spam mail.
               The subject line may have a user-defined string prepended to it
               for spam mail.
           X-Spam-* headers for all mails
               Depending on the configuration, zero or more headers with names
               beginning with "X-Spam-" will be added to mail depending on
               whether it is spam or ham.
           spam message with report_safe
               If report_safe is set to true (1), then spam messages are
               encapsulated into their own message/rfc822 MIME attachment
               without any modifications being made.
               If report_safe is set to false (0), then the message will only
               have the above headers added/modified.
       $status->action_depends_on_tags($tags, $code, @args)
           Enqueue the supplied subroutine reference $code, to become runnable
           when all the specified tags become available. The $tags may be a
           simple scalar - a tag name, or a listref of tag names. The
           subroutine &$code when called will be passed a "permessagestatus"
           object as its first argument, followed by the supplied (optional)
           list @args .
       $status->set_tag($tagname, $value)
           Set a template tag, as used in "add_header", report templates, etc.
           This API is intended for use by plugins.  Tag names will be
           converted to an all-uppercase representation internally.
           $value can be a simple scalar (string or number), or a reference to
           an array, in which case the public method get_tag will join array
           elements using a space as a separator, returning a single string
           for backward compatibility.
           $value can also be a subroutine reference, which will be evaluated
           each time the template is expanded. The first argument passed by
           get_tag to a called subroutine will be a PerMsgStatus object (this
           module's object), followed by optional arguments provided a caller
           to get_tag.
           Note that perl supports closures, which means that variables set in
           the caller's scope can be accessed inside this "sub". For example:
               my $text = "hello world!";
               $status->set_tag("FOO", sub {
                         my $pms = shift;
                         return $text;
                       });
           See "Mail::SpamAssassin::Conf"'s "TEMPLATE TAGS" section for more
           details on how template tags are used.
           "undef" will be returned if a tag by that name has not been
           defined.
       $string = $status->get_tag($tagname)
           Get the current value of a template tag, as used in "add_header",
           report templates, etc. This API is intended for use by plugins.
           Tag names will be converted to an all-uppercase representation
           internally.  See "Mail::SpamAssassin::Conf"'s "TEMPLATE TAGS"
           section for more details on tags.
           "undef" will be returned if a tag by that name has not been
           defined.
       $string = $status->get_tag_raw($tagname, @args)
           Similar to "get_tag", but keeps a tag name unchanged (does not
           uppercase it), and does not convert arrayref tag values into a
           single string.
       $status->set_spamd_result_item($subref)
           Set an entry for the spamd result log line.  $subref should be a
           code reference for a subroutine which will return a string in
           'name=VALUE' format, similar to the other entries in the spamd
           result line:
             Jul 17 14:10:47 radish spamd[16670]: spamd: result: Y 22 - ALL_NATURAL,
             DATE_IN_FUTURE_03_06,DIET_1,DRUGS_ERECTILE,DRUGS_PAIN,
             TEST_FORGED_YAHOO_RCVD,TEST_INVALID_DATE,TEST_NOREALNAME,
             TEST_NORMAL_HTTP_TO_IP,UNDISC_RECIPS scantime=0.4,size=3138,user=jm,
             uid=1000,required_score=5.0,rhost=localhost,raddr=127.0.0.1,
             rport=33153,mid=<9PS291LhupY>,autolearn=spam
           "name" and "VALUE" must not contain "=" or "," characters, as it is
           important that these log lines are easy to parse.
           The code reference will be called by spamd after the message has
           been scanned, and the "PerMsgStatus::check()" method has returned.
       $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 "Mail::SpamAssassin" factory,
           this method should be called to ensure Perl's garbage collection
           will clean up old status objects.
       $name = $status->get_current_eval_rule_name()
           Return the name of the currently-running eval rule.  "undef" is
           returned if no eval rule is currently being run.  Useful for
           plugins to determine the current rule name while inside an eval
           test function call.
       $status->get_decoded_body_text_array ()
           Returns the message body, with base64 or quoted-printable encodings
           decoded, and non-text parts or non-inline attachments stripped.
           It is returned as an array of strings, with each string
           representing one newline-separated line of the body.
       $status->get_decoded_stripped_body_text_array ()
           Returns the message body, decoded (as described in
           get_decoded_body_text_array()), with HTML rendered, and with
           whitespace normalized.
           It will always render text/html, and will use a heuristic to
           determine if other text/* parts should be considered text/html.
           It is returned as an array of strings, with each string
           representing one 'paragraph'.  Paragraphs, in plain-text mails, are
           double-newline-separated blocks of multi-line text.
       $status->get (header_name [, default_value])
           Returns a message header, pseudo-header, real name or address.
           "header_name" is the name of a mail header, such as 'Subject',
           'To', etc.  If "default_value" is given, it will be used if the
           requested "header_name" does not exist.
           Appending ":raw" to the header name will inhibit decoding of
           quoted-printable or base-64 encoded strings.
           Appending a modifier ":addr" to a header field name will cause
           everything except the first email address to be removed from the
           header field.  It is mainly applicable to header fields 'From',
           'Sender', 'To', 'Cc' along with their 'Resent-*' counterparts, and
           the 'Return-Path'. For example, all of the following will result in
           "example@foo":
           example@foo
           example@foo (Foo Blah)
           example@foo, example@bar
           display: example@foo (Foo Blah), example@bar ;
           Foo Blah <example@foo>
           "Foo Blah" <example@foo>
           "'Foo Blah'" <example@foo>
           Appending a modifier ":name" to a header field name will cause
           everything except the first display name to be removed from the
           header field. It is mainly applicable to header fields containing a
           single mail address: 'From', 'Sender', along with their
           'Resent-From' and 'Resent-Sender' counterparts.  For example, all
           of the following will result in "Foo Blah". One level of single
           quotes is stripped too, as it is often seen.
           example@foo (Foo Blah)
           example@foo (Foo Blah), example@bar
           display: example@foo (Foo Blah), example@bar ;
           Foo Blah <example@foo>
           "Foo Blah" <example@foo>
           "'Foo Blah'" <example@foo>
           There are several special pseudo-headers that can be specified:
           "ALL" can be used to mean the text of all the message's headers.
           "ALL-TRUSTED" can be used to mean the text of all the message's
           headers that could only have been added by trusted relays.
           "ALL-INTERNAL" can be used to mean the text of all the message's
           headers that could only have been added by internal relays.
           "ALL-UNTRUSTED" can be used to mean the text of all the message's
           headers that may have been added by untrusted relays.  To make this
           pseudo-header more useful for header rules the 'Received' header
           that was added by the last trusted relay is included, even though
           it can be trusted.
           "ALL-EXTERNAL" can be used to mean the text of all the message's
           headers that may have been added by external relays.  Like
           "ALL-UNTRUSTED" the 'Received' header added by the last internal
           relay is included.
           "ToCc" can be used to mean the contents of both the 'To' and 'Cc'
           headers.
           "EnvelopeFrom" is the address used in the 'MAIL FROM:' phase of the
           SMTP transaction that delivered this message, if this data has been
           made available by the SMTP server.
           "MESSAGEID" is a symbol meaning all Message-Id's found in the
           message; some mailing list software moves the real 'Message-Id' to
           'Resent-Message-Id' or 'X-Message-Id', then uses its own one in the
           'Message-Id' header.  The value returned for this symbol is the
           text from all 3 headers, separated by newlines.
           "X-Spam-Relays-Untrusted" is the generated metadata of untrusted
           relays the message has passed through
           "X-Spam-Relays-Trusted" is the generated metadata of trusted relays
           the message has passed through
       $status->get_uri_list ()
           Returns an array of all unique URIs found in the message.  It takes
           a combination of the URIs found in the rendered (decoded and HTML
           stripped) body and the URIs found when parsing the HTML in the
           message.  Will also set $status->{uri_list} (the array as returned
           by this function).
           The returned array will include the "raw" URI as well as "slightly
           cooked" versions.  For example, the single URI
           'http://%77&#00119;%77.example.com/' will get turned into: (
           'http://%77&#00119;%77.example.com/', 'http://www.example.com/' )
       $status->get_uri_detail_list ()
           Returns a hash reference of all unique URIs found in the message
           and various data about where the URIs were found in the message.
           It takes a combination of the URIs found in the rendered (decoded
           and HTML stripped) body and the URIs found when parsing the HTML in
           the message.  Will also set $status->{uri_detail_list} (the hash
           reference as returned by this function).  This function will also
           set $status->{uri_domain_count} (count of unique domains).
           The hash format looks something like this:
             raw_uri => {
               types => { a => 1, img => 1, parsed => 1 },
               cleaned => [ canonified_uri ],
               anchor_text => [ "click here", "no click here" ],
               domains => { domain1 => 1, domain2 => 1 },
             }
           "raw_uri" is whatever the URI was in the message itself
           (http://spamassassin.apache%2Eorg/).
           "types" is a hash of the HTML tags (lowercase) which referenced the
           raw_uri.  parsed is a faked type which specifies that the raw_uri
           was seen in the rendered text.
           "cleaned" is an array of the raw and canonified version of the
           raw_uri (http://spamassassin.apache%2Eorg/,
           http://spamassassin.apache.org/).
           "anchor_text" is an array of the anchor text (text between <a> and
           </a>), if any, which linked to the URI.
           "domains" is a hash of the domains found in the canonified URIs.
           "hosts" is a hash of unstripped hostnames found in the canonified
           URIs as hash keys, with their domain part stored as a value of each
           hash entry.
       $status->clear_test_state()
           Clear test state, including test log messages from
           "$status->test_log()".
       $status->got_hit ($rulename, $desc_prepend [, name => value, ...])
           Register a hit against a rule in the ruleset.
           There are two mandatory arguments. These are $rulename, the name of
           the rule that fired, and $desc_prepend, which is a short string
           that will be prepended to the rules "describe" string in output
           reports.
           In addition, callers can supplement that with the following
           optional data:
           score => $num
               Optional: the score to use for the rule hit.  If unspecified,
               the value from the "Mail::SpamAssassin::Conf" object's
               "{scores}" hash will be used (a configured score), and in its
               absence the "defscore" option value.
           defscore => $num
               Optional: the score to use for the rule hit if neither the
               option "score" is provided, nor a configured score value is
               provided.
           value => $num
               Optional: the value to assign to the rule; the default value is
               1.  tflags multiple rules use values of greater than 1 to
               indicate multiple hits.  This value is accessible to meta
               rules.
           ruletype => $type
               Optional, but recommended: the rule type string.  This is used
               in the "hit_rule" plugin call, called by this method.  If
               unset, 'unknown' is used.
           tflags => $string
               Optional: a string, i.e. a space-separated list of additional
               tflags to be appended to an existing list of flags in
               $self->{conf}->{tflags}, such as: "nice noautolearn multiple".
               No syntax checks are performed.
           description => $string
               Optional: a custom rule description string.  This is used in
               the "hit_rule" plugin call, called by this method. If unset,
               the static description is used.
           Backward compatibility: the two mandatory arguments have been part
           of this API since SpamAssassin 2.x.  The optional name=<gtvalue>
           pairs, however, are a new addition in SpamAssassin 3.2.0.
       $status->create_fulltext_tmpfile (fulltext_ref)
           This function creates a temporary file containing the passed scalar
           reference data (typically the full/pristine text of the message).
           This is typically used by external programs like pyzor and dccproc,
           to avoid hangs due to buffering issues.   Methods that need this,
           should call $self->create_fulltext_tmpfile($fulltext) to retrieve
           the temporary filename; it will be created if it has not already
           been.
           Note: This can only be called once until
           $status->delete_fulltext_tmpfile() is called.
       $status->delete_fulltext_tmpfile ()
           Will cleanup after a $status->create_fulltext_tmpfile() call.
           Deletes the temporary file and uncaches the filename.
       all_from_addrs_domains
           This function returns all the various from addresses in a message
           using all_from_addrs() and then returns only the domain names.
