Abstract

L'invention concerne un procédé et un dispositif de traitement de courriels via l'Internet. Afin de rejeter les pourriels, ne nécessitant pas le changement d'adresse courriel de l'expéditeur et n'affectant aucunement le destinataire, une unité de mémorisation garde l'information sur l'expéditeur d'un courriel envoyé via l'Internet. L'acceptation d'un courriel reçu est rejetée si l'information relative à l'expéditeur du courriel n'est pas enregistrée dans l'unité de mémorisation. Si nécessaire, l'information d'authentification contenue sous forme d'information destinataire est assemblée ou on décide si oui ou non on peut effectuer une correspondance du nombre de courriels reçus. Ensuite, l'acceptation ou la permission concernant le courriel est octroyée à l'expéditeur du courriel.
