Anti-spam protects both end users and administrators of e-mail systems from spamming. Some of the techniques involved are embedded in products, services and software to ease the burden on users and administrators. No one technique is a complete solution to the spam problem, and each makes trade-offs between incorrectly rejecting legitimate e-mail vs not rejecting all spam, and the associated costs in time and effort. This means it is important that you understand what technique works for you. IDG Connect can help by offering a range of white papers, webcasts and spam technique guides.
