Abstract
A method, system and computer program product for collaborative filtering of junk electronic mail (e-mail) are provided. The method includes receiving an e-mail message at a service provider, where the e-mail message includes a source address and a recipient address. The method further includes searching a collaborative junk register (CJR) for the recipient address in a group member list, where the group member list includes multiple member addresses and a junk address. The method additionally includes comparing the source address to the junk address. The method also includes filtering the e-mail message at the service provider to prevent delivery of the e-mail message in response to locating the recipient address in the CJR and identifying source address as the junk address.
