In order to simplify prevention of unauthorized or malicious electronic mail transmission, a mail server comprises a password conversion table which shows registered correlation among user ID, a formal password, and a virtual password different from the formal password, both assigned to each user for user authentication by a general-purpose mail server. A user is informed of only a virtual password. When electronic mail having a virtual password and addressed to an outsider of a company is sent from a client PC, a password conversion processor converts the virtual password into a corresponding formal password with reference to the password conversion table, and the virtual SMTP server function processor sends the electronic mail now having the formal password to the general-purpose mail server. A user at a client PC cannot access the general-purpose mail server using a virtual password as the user is not authenticated using the virtual password. |
