Hola, buenas tardes.

Estoy teniendo un problema en el servidor zimbra que tenemos.

De un día para el otro dejó de colocarle a cada mail los headers "x-spam", por lo que todos los correos que habitualmente iban a la carpeta spam ahora van a la bandeja de entrada.

Estuve tratando de buscar la solución sin éxito.

Agradezco cualquier ayuda que me puedan brindar.

Acá pongo un ejemplo de como se ven los mensajes:
