Title (EN) METHOD AND APPARATUS FOR MAINTAINING REPUTATION LISTS OF IP ADDRESSES TO DETECT EMAIL SPAM
(FR) PROCEDE ET APPAREIL POUR LA TENUE DE LISTES DE REPUTATION D'ADRESSES IP POUR LA DETECTION DE COURRIEL POUBELLE
Abstract:
(EN) A method and system to maintain lists of IP addresses for detection of email spam are described. In one embodiment, the method includes receiving email messages from senders associated with Internet Protocol (IP) addresses, filtering the email messages and the identified spam to a server. The method further includes receiving, from the server, IP address lists generated based on the statistics, and filtering new email messages using the IP address lists. The IP address lists received from the server may include a list of safe IP addresses, a list of suspect IP addresses and a list of proxy IP addresses.
(FR) La présente invention a trait à un procédé et un système pour la tenue de listes d'adresses IP pour la détection de courriel poubelle. Dans un mode de réalisation, le procédé comprend la réception de courriels en provenance d'expéditeurs associés à des adresses IP, le filtrage des courriels pour l'identification de courriel poubelle et l'envoi de statistiques concernant les courriels et le courriel poubelle identifié à un serveur. Le procédé comprend également la réception, en provenance du serveur, de listes d'adresses IP basées sur les statistiques, et le filtrage de nouveaux courriels au moyen des listes d'adresses IP. Les listes d'adresses IP reçues du serveur peuvent inclure une liste d'adresses IP sures et une liste d'adresses IP suspectes et une liste d'adresses IP de serveur mandataire ouverte.
