SMC anti-spam filter for Sendmail 1.7
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 includes features for protecting recipients from dangerous attachments and HTML includes. Since 2003 it uses a set of original algorithms, including "Check relay by NS", which simulates a dynamic whitelisting technique, and "Check delays", also known as "Greylisting" now.
