PROBLEM TO BE SOLVED: To provide social network E-mail filtering. SOLUTION: E-mail addresses included in an address book of a user is used to identify address books including another group of E-mail addresses. Multiple iterations may be used to identify several groups of E-mail addresses, representing a social network of the user. When an E-mail message addressed to the user is received, the message is trusted if the sending E-mail address is within the user's social network. Otherwise, the message is flagged as junk mail. Varying trust levels may be applied to messages that are received based on a distance within a social network between the sending E-mail address and the user, and/or how often the sending E-mail address appears within the social network.
