The release of the spam filtering platform SpamAssassin 4.0.0 has been published. SpamAssassin offers a comprehensive approach to blocking decisions: initially, a message undergoes a series of checks (contextual analysis, black and white lists DNSBL, trained Bayesian classifiers, signature checks, sender authentication via SPF and DKIM, etc.). After evaluating the message using various methods, a specific weight coefficient is accumulated. If the calculated coefficient exceeds a certain threshold, the message is blocked or marked as spam. Automatic rule update tools are supported. The package can be used on both client and server systems. The SpamAssassin code is written in Perl and is distributed under the Apache 2.0 license. <\/p>\n
