Je viens d'avoir une mauvaise surprise après un envoi de newsletter depuis le site WordPress que j'héberge sur Legtux. J'ai une quarantaine d'e-mail Undelivered Mail Returned to Sender ! Outlook semble avoir décidé de bloquer Legtux, du moins l'adresse IP OVH de Legtux ?
D'avance merci pour toute aide !
