En una de las cuentas alojadas en mi servidor. Éste tiene autenticación sasl activada y utiliza postfix. Me da rollo que alguien esté utilizando mi servidor para enviar spam, pero me parece muy raro, leyendo las cabeceras del mismo, parece como si el error no lo devolviese a mi servidor, si no que fuese un mail enviado con las caracteristicas de un error.
¿Alguien podría decirme algo a este respecto?¿Es normal?¿Como lo evito?
PS. Tengo amavisd y spamassasin instalados también
Muchas gracias.
