PROBLEM TO BE SOLVED: To provide an internal mail transmission controlling system which prevents information included in internal mails from leaking when the internal mails are transmitted to external terminal devices. SOLUTION: The internal mail transmission controlling system 1 comprises a mail server 2 and an internal terminal machine 3 communicatively connected via a communication network 4. In addition, the internal terminal machine 3 transmits internal mails with control codes set. The mail server 2 preliminarily stores a forwarding setting when an internal mail receiver is absent, determines whether a received internal mail is to be forwarded based on the stored forwarding setting, and forwards an internal mail determined to be forwardable, based on control codes set to the internal mail, to an external terminal machine 8 set in the forwarding setting.
