Abstract
L'invention concerne un serveur mandataire de filtrage actif filtrant le courrier électronique-poubelle reçu d'hôtes Internet distants utilisant le protocole SMTP (Simple Mail Transfer Protocol) au niveau d'un agent de transfert des messages. Ledit serveur mandataire (1104) sonde activement les hôtes distants qui tentent d'envoyer du courrier à un serveur de courrier électronique protégé afin d'identifier les ordinateurs personnels commutés, les relais ouverts et les messages électroniques falsifiés. Ledit système offre plusieurs couches de défense, notamment : un filtrage temps de connexion basé sur l'adresse IP, l'identification des ordinateurs personnels commutés tentant d'envoyer des messages, la vérification des relais (ouverts) permissifs, la vérification de la validité de l'adresse de l'expéditeur et le filtrage des en-têtes des messages. Si un message passe par toutes les couches pertinentes, il est directement remis à tous ses destinataires. Une liste blanche (1094) de destinataires permet à l'utilisateur ou à l'administrateur système d'identifier des expéditeurs et/ou domaines particuliers acceptables. Si un ou plusieurs destinataires ont accepté de recevoir du courrier émanant de l'expéditeur, le message est remis à ces destinataires, mais il est rejeté ou mis en quarantaine pour le reste des destinataires.
