Hola a todos,
Creo que nuevamente tengo un problema grande, tengo postfix 1.1.x con sasl y
mis reglas de filtrado ok (asi creo) pero me atacan con multiples conexiones
Obviamente según master.cf llego a 50 procesos y el servidor empieza a
funcionar lentisimo y retrasa enormemente la entrega.
Intente con:
smtpd_delay_reject = no
para que la restricción tomara efecto lo antes posible pero el problema no se
soluciona
Que puedo hacer contra esto ?
PD: son todos los mails de eduardo.morales pero aunque lo tenga en mi lista de
access como denegado, da lo mismo por que lo que importa es que abrio el
proceso y la conexion.
