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

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'));

DESCRIPTION

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 Mail::Message::Wrapper::SpamAssassin object.

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

Mail::Box::Search::SpamAssassin->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.
