Mon Exchange est relais SMTP ouvert

[fboutheon]

Bonjour,

Mon serveur exchange 2003 est un relais SMTP ouvert visiblement.
Dans ma files d'attente, j'ai plein de nom de domaine qui essais d'envoyer des mails et ce presque toujours à la meme adresse ( "CUNA"<support@cuna.org>).
Comment faire pour remédier à ce problème sachant que normalement je suis paramétré pour ne pas etre relais ouvert?
Y a t'il quelque chose à voire du côté de chez Oléane?

Merci

Plutôt qu'un long discours, je te propose une longue lecture

Bonjour,

Mon serveur est bien paramétré comme indiqué.
Pourtant toujours le soucis dans la files d'attente.
