To allow inspecting whether a security check of a planned outgoing email is finished in an outgoing email check system, a check data providing apparatusof an outgoing email check systemstores check information distributed from a check information management apparatus, appends check data generated based on the check information to a header of a checked planned outgoing email, and transmits the email to an email transmitting apparatus. A check data inspecting apparatusstores the check information distributed from the check information management apparatus, inspects the check data extracted from the planned outgoing email received from the email transmitting apparatusbased on the check information, determines that the transmission is permitted when the check data of the planned outgoing email matches the check information, and determines that the transmission is rejected when the check data does not match the check information. The email transmitting apparatusexecutes a transmission process only for the planned outgoing email for which the transmission is permitted.

Outgoing email check system, check data providing apparatus, check data inspecting apparatus, and outgoing email check method

An email wrong transmission preventing apparatus calculates memory ratios of addresses of emails in a transmission log by a model expression in which the memory ratios decline over time, compiles the memory ratios of the emails for each destination to set weights, and records the weights in a user weight list. When receiving a planned outgoing email, the apparatus compares the weight of the destination of the planned outgoing email obtained by referring to the user weight list with a predetermined threshold and determines that the destination is 'reliable' only if the weight is over the threshold. If even one of the destinations of the planned outgoing email is not 'reliable', the apparatus causes a sender terminal to display an address check screen to prompt address checking. When &#x201c;checked&#x201d; is inputted, the apparatus transfers the planned outgoing email to an email transmission server.
