Abstract
A method, network element, system, and software product are presented for differentiating spam from email so that the spam can be deleted, or placed in a separate location, or identified as spam. Email is received at a server, and the email is initially filtered to differentiate at least part of the spam from the other email. Then the filter is improved, for example by using an updated database to identify spam. Subsequently, the email is intermediately filtered to differentiate further spam at least once before a user device attempts to access the email. Some of the further spam was overlooked by the initial filtering, but not overlooked by the intermediate filtering.
