SpamAssassin implementa un enfoque integral para la toma de decisiones sobre el bloqueo: el mensaje se somete a una serie de comprobaciones (an\u00e1lisis contextual, listas negras y blancas DNSBL, clasificadores bayesianos entrenables, verificaci\u00f3n por firmas, autenticaci\u00f3n del remitente mediante SPF y DKIM, etc.). Despu\u00e9s de evaluar el mensaje con diversos m\u00e9todos, se acumula un coeficiente de peso determinado. Si el coeficiente calculado excede un umbral espec\u00edfico, el mensaje se bloquea o se marca como spam. Se admiten herramientas de actualizaci\u00f3n autom\u00e1tica de las reglas de filtrado.
