The SpamAssassin implements a comprehensive approach to decision-making regarding blocking: the message undergoes a series of checks (context analysis, black and white lists DNSBL, trainable Bayesian classifiers, signature checks, sender authentication via SPF and DKIM, etc.). After assessing the message through various methods, a certain weight coefficient is accumulated. If the calculated coefficient exceeds a specific threshold \u2014 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.
