=head1 NAME

Mail::Box::Search::SpamAssassin - select spam messages with Mail::SpamAssassin

=head1 INHERITANCE

 Mail::Box::Search::SpamAssassin
   is a Mail::Box::Search
   is a Mail::Reporter

=head1 SYNOPSIS

 use Mail::Box::Manager;
 my $mgr    = Mail::Box::Manager->new;
 my $folder = $mgr->open('Inbox');

 my $spam = Mail::Box::Search::SpamAssassin->new;
 if($spam->search($message)) {...}

 my @msgs   = $filter->search($folder);
 foreach my $msg ($folder->messages)
 {   $msg->delete if $msg->label('spam');
 }

 my $spam2 = Mail::Box::Search::SpamAssassin
               ->new(deliver => 'DELETE');
 $spam2->search($folder);
 $mgr->moveMessages($spamfolder, $folder->messages('spam'));

=head1 DESCRIPTION

I<Spam> means "unsollicited e-mail", and is as name derived from a
Monty Python scatch.  Although Monty Python is fun, spam is a pain:
it needlessly spoils minutes of time from most people: telephone
bills, overful mailboxes which block honest e-mail, and accidentally
removal of honest e-mail which looks like spam.  Spam is the pest
of Internet.

Happily, Mail::Box can be used as spam filter, in combination with
the useful Mail::SpamAssassin module (which must be installed separately).
Each message which is searched is wrapped in a
L<Mail::Message::Wrapper::SpamAssassin|Mail::Message::Wrapper::SpamAssassin> object.

The spam-assassin module version 2 is not really well adapted for
L<Mail::Message|Mail::Message> objects, which will make this search even slower than
spam-detection already is.

=item Mail::Box::Search::SpamAssassin-E<gt>B<new>(%options)

Create a spam filter.  Internally, a Mail::SpamAssassin object is
maintained.

Only the whole message can be searched; this is a limitation of
the Mail::SpamAssassin module.

=item binaries => BOOLEAN

=item decode => BOOLEAN

=item delayed => BOOLEAN

=item deleted => BOOLEAN

=item deliver => undef|CODE|'DELETE'

=item in => 'HEAD'|'BODY'|'MESSAGE'

=item label => STRING|undef

Mark all selected message with the specified STRING.  If this
option is explicitly set to C<undef>, the label will not be set.

=item limit => NUMBER

=item log => LEVEL

=item logical => 'REPLACE'|'AND'|'OR'|'NOT'|'AND NOT'|'OR NOT'

=item multiparts => BOOLEAN

=item rewrite_mail => BOOLEAN

Add lines to the message header describing the results of the spam
scan. See Mail::SpamAssassin::PerMsgStatus subroutine rewrite_mail.

=item sa_options => HASH

Options to create the internal Mail::SpamAssassin object; see its
manual page for the available options.  Other setting may be provided
via SpamAssassins configuration file mechanism, which is explained in
L<Mail::SpamAssassin::Conf>.

=item spam_assassin => OBJECT

Provide a Mail::SpamAssassin object to be used for searching spam.  If
none is specified, one is created internally.  The object can be
retrieved with assassinator().

=item Error: Package $package does not implement $method.
