Abstract

Spams, extolling the merits of some types of products or services, encumber mailboxes. In light of the existing laws in France and the European directives in place, spam is illegal. However, illegality does not prevent their issuers from pursuing their activities. The development of this advertising medium is mainly due to the expertise and the professionalism of spammers who, in order to reach a maximum public, use sophisticated techniques allowing to enrich their address books, on the one hand, and regularly create new forms of spams to bypass the filters anti-spam and optimize as a result the rate of delivery of their messages, on the other hand.
