Looks like it's just trying to provide sendmail with the kind of
functionality which is built in to Exim. I find Exim's ACL language much
easier to use than perl, because it's actually designed for processing
email. And of course you can call out to separate scanning processes
(running with their own uid) such as spamd, clamd etc.
