Hi, I have that error message (in french) when I try to send an email :

Impossible d'envoyer le message car le serveur a refusé l'adresse de messagerie de l'expéditeur. Cette adresse était 'marti@wanvoyage.com'. Objet 'Fw: 3 autorisations visas groupe du 20 au 27 mai 2006', Compte : 'mail.wanvoyage.com', Serveur : 'relay.skynet.be', Protocole : SMTP, Réponse du serveur : '451 4.1.8 Domain of sender address marti@wanvoyage.com does not resolve', Port : 25, Sécurisé (SSL) : Non, Erreur de serveur : 451, Numéro d'erreur : 0x800CCC78

We verified everything, including DNS, all is ok.... What's the problem ?

Thanks!
