SMC anti-spam filter for Sendmail
by True Audio Software
SMC anti-spam non-context e-mail filter is an Sendmail milter plugin, that is designed to significantly reduce the amount of junk email you receive. It uses dynamic local and DNS-based remote whitelists, blacklists, and an original auto-authentication system for unknown but legitimate senders. It uses a set of original algorithms, including "Check delays", also known as "Greylisting" now.
