The invention discloses a mail security protection method based on security level control. A server carries out security level classification on users and mails, and configures corresponding security levels of the mails according to keywords; and when a user sends a mail, the server searches and sets corresponding security level according to the keywords in the mail, meanwhile, carries out security level matching according to the security level of the user sending the mail and the mail set security level, and sends the mail when the security levels match.
