A filter mechanism for unwanted e-mail messages uses a downloadable central source (1, 2) of filter rule data. User reports of received unwanted e-mail messages are relayed back to the central source of the filter data and used to automatically update that filter data. An algorithmic approach to identifying characteristics of unwanted e-mail messages may be applied based upon the preponderance of predetermined words within an e-mail message or characteristics of the addressee list. If an e-mail message is identified as suspect, but not definitely unwanted, then it may be encapsulated within a HTML document and sent to its addressee together with buttons (28) allowing the recipient to provide feedback in the form of votes as to whether or not that email message is unwanted. This recipient feedback may be used to establish a new local rule.
