Saludos, tengo un problema, administro un Centos 5 con Spamassasin, sendmail, clamav y MailScanner, todo funciona correcto pero por alguna razon me marca todos los correos con el tag {?SPAM} aun cuando la calificacion que le da Mailscanner es inferior a la minima para ser considerada spam (en mi caso minima 11 maximo 15), cuando envio a proposito un correo tipo spam tengo este log:

Como la calificacion dio 22.928 el Mailscanner simplemente no entrego el mensaje por ser considerado SPAM de alto riesgo, pero cuando envio un email tipo "hola mundo" super sencillo el log muestra esto:

Me marco el email como spam aunque la calificacion que me dio fue menor al rango minimo (dio 10 puntos en este email, y con cualquier email simple o "normal" hace lo mismo, lo marca con el tag {?SPAM}

La seccion del mailscanner.conf referente al spamAssasin la tengo asi:

# This replaces the SpamAssassin configuration value 'required_hits'.
# If a message achieves a SpamAssassin score higher than this value,
# it is spam. See also the High SpamAssassin Score configuration option.
# This can also be the filename of a ruleset, so the SpamAssassin
# required_hits value can be set to different values for different messages.
Required SpamAssassin Score = 11

# If a message achieves a SpamAssassin score higher than this value,
# then the "High Scoring Spam Actions" are used. You may want to use
# this to deliver moderate scores, while deleting very high scoring messsages.
# This can also be the filename of a ruleset.
High SpamAssassin Score = 15

Alguien tiene idea de cual puede ser mi problema, Saludos.
