1. Perl-based spam filter using text analysis This package contains a script that is designed to be called from a user's .forward or .procmailrc file, and acts to filter out all junk or spam e-mail. It also contains a daemon and client (written in C) designed for high load servers, reducing loading overhead. It includes automatic white-listing, RBL testing, and header and body testing for common spam contents. With librazor-perl, it also checks messages against an online collaborative database.
