Abstract (en)
[origin: WO2004081734A2] An e-mail filtering method and system that categorize received e-mail messages based on information about the origin contained in the message header and the SMTP session used to send the message. This data and other information about the message is then sent by each member of an e-mail network to one or more central databases (66) which stores the information and compiles statistics about e-mails sent from the origin to indicate the likelihood that the e-mail is unsolicited and determine the reputation of the origin (a good reputation indicates the sender sends solicited messages while a bad reputation indicates the sender sends unsolicited e-mail messages). Information from the central database is then sent to recipients (20) in order to determine the likelihood that a received e-mail message is spam.
