[Postfix-es] Virus Sober

[Juan Carlos Bravo Celis]

Estimados amigos,
tengo un problema con el virus worm.sober, yo teng configurado el postfix +
amavis + spamassassin, pero aparentemente tengo algo mal configurado que me
estan llegando muchos correos con el mensaje : " su correo no ha sido
entregado a los siguientes destinatarios y me muestra una lista muy grande
de direcciones y al final me indica que mi correo tiene el virus sober.u y
esto ya me ha traido problemas debido a que me pusieron en la lista negra de
spamhaus.org, y actualmente me estan llegando 100 mil correos por dia con
ese contenido, les envio el resultado de ejecutar postconf -n, espero puedan
ayudarme
