=head1 NAME
RT::Interface::Email::Filter::SpamAssassin - Spam filter for RT
=head1 SYNOPSIS
@RT::MailPlugins = ("Filter::SpamAssassin", ...);
=head1 DESCRIPTION
This plugin checks to see if an incoming mail is spam (using
C<spamassassin>) and if so, rewrites its headers. If the mail is very
definitely spam - 1.5x more hits than required - then it is dropped on
the floor; otherwise, it is passed on as normal.
