Aldo,

Es fundamental que hagas ese sa-update a menudo, sino, Spamassassin se 
vuelve inútil. De hecho deberías tenerlo en una tarea de cron. Las 
técnicas de los Spammers se refinan y spamassassin debe actualizar las 
reglas para adaptarse de forma periódica. Desconozco el tipo de conexión 
que tienes, pero si estas aceptando mails de forma pública a través de 
esa conexión no debería ser un problema actualizar con sa-update.

Recuerda reiniciar spamassassin en cualquiera de sus versiones para que 
los cambios en las reglas sean efectivos.

Un saludo,
