A method for controlling the transmission of messages (Emails) from a first user (User A) to a second user (User B) in order to detect the transmission of unwanted Emails or spam. The transmission of an Email from User A to User B occurs via a first mail server, associated to a first Internet Service Provider (ISP A) of user A, and a second mail server, associated to a second Internet Service Provider (ISP B) of user B. In this method, ISP A transmits identification parameters to a legal user database provided with an "Email Name Service" (ENS). The parameters comprise trustworthy level of the User A. At the reception of the Email, the second mail server checks the legal user database and transfers the Email to User B only if User A is identified by the Email Name Service and if his/her trustworthy level is acceptable.
