J'ai donc décidé de prendre le taureau par les cornes, et j'ai mis en place du greylisting [3] Le principes et simple: chaque mail qui arrive est d'abord refusé par postfix, qui stocke dans une base de donnée l'adresse IP de l'expéditeur, l'adresse email de l'expéditeur, et l'adresse email du destinataire. Tout serveur SMTP "réglo" va tenter plus tard un nouvel envoi, qui sera alors accepté. Les spammeurs, eux, majoritairement, ne feront pas de nouvel envoi.
