spam detection is usually performed once at the level of the email provider thanks to the pre-installed filters, and secondly it can be enabled by the installation of an additional spam blocker. Spam detection has become a necessity because the number of unsolicited mail messages is on the rise. Although punishable by law, spamming continues to be a common practice for lots of businesses that hide on the world wide web market and fool naive Internet users. Spam prevention and spam detection remain the only ways to limit the impact of spam for the moment.

Spam prevention is pretty basic: do not disclose your email address easily. This means that you must not enter the email address on web pages that require registration; better get a secondary address and use that for the purpose. Do not respond to unknown senders, and most important do not forward messages such as jokes, warnings and other kinds of messages that allow for the accumulation of large numbers of email addresses. Spam detection on the other hand can be performed on the personal computer or on the server, and in both cases it requires the installation of some software blocking tools.

Filters and blockers perform spam detection. First of all, filters separate legitimate messages from possible spam. Blockers on the other hand perform spam detection and cleaning without allowing the access to the personal computer. When the anti-spam software is installed on the server, things are even better because the viewing of the emails with a spam potential is possible without their being transferred in the computer memory. Spam detection can thus be achieved on the basis of the sender’s ID, the keywords specific to spamming and several other criteria integrated in the technology.

Just as the spam detection tool means constantly improve, so do the spammers’ strategies to fool blockers and filters and get into people’s mail box. Up to now, there is no total protection against spam. Who knows whether things will ever change and more anti-spam measures will be possible? If kept at this level, spam raises few problems, on condition that you don’t open mails from strangers that somehow manage to pass the most advanced anti-spam tool.
