=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');
}

->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.
=head1 METHODS

Mail::Box::Search::SpamAssassin-E<gt>B<new>(OPTIONS)
=over 4
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.

via SpamAssassins configuration file mechanism, which is explained in
L<Mail::SpamAssassin::Conf>.
=back
. spam_assassin => OBJECT
=over 4
Provide a Mail::SpamAssassin object to be used for searching spam. If
none is specified, one is created internally. The object can be
retreived with assassinator().

=head1 DIAGNOSTICS
Error: Package $package does not implement $method.
=over 4
Fatal error: the specific package (or one of its superclasses) does not
implement this method where it should. This message means that some other
related classes do implement this method however the class at hand does
not. Probably you should investigate this and probably inform the author
of the package.
