There are two levels of spam detection, one at the level of the server and another on the personal computer, depending on where the filters have been installed. Spam detection has become a necessity because the number of unsolicited mail messages is on the rise. Even if illegal, the action of spamming is conducted by very many dishonest businesses that use the world wide wed to hide their identity and dupe as many people as possible. For the moment, there are just two main ways to limit junk mail: spam prevention and spam detection.

Spam prevention is pretty basic: do not disclose your email address easily. Avoid filling in online forms and registration boxes with your email address. Do not answer emails whose sender you do not know, 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. On the other hand, the installation of the software blocking tools is necessary for the efficient spam detection.

Blockers and filters perform spam detection. First of all, filters separate legitimate messages from possible spam. Blockers are tools that don’t allow the spma access to the personal computer. Viewing the emails on the server represents one other way of preventing computer infection with viruses and malware. Spam detection can thus be achieved on the basis of the spamming keywords, the sender’s ID or technology-integrated criteria.

Just as the email spam detection means constantly improve, so do the spammers’ strategies to fool filters and blockers and get into people’s mail box. Up to now, there is no total protection against spam. It is also not known whether things will ever be different for the matter and whether there will be more than 99% anti-spam protection available. If kept at this level, spam is not that much a problem, on condition that the mails whose sender you don’t know be deleted.
