PROBLEM TO BE SOLVED: To provide an electronic mail processing device Upm capable of preventing a transmission of an electronic mail excessively long and incomplete to be read through to the end to a receiver. SOLUTION: In this electronic mail processing device Upm, an excess of the number of character determination unit Pde takes out the upper limit number of character ULc determined in the electronic mail service by a communication business specified with a domain name set in this electronic mail Me with a reference of an upper limit number of character data base DBu1. Thereafter, the excess of the number of character determination unit Pde compares the number of character of the electronic mail Me with the upper limit number of character ULc, and when the number of character exceeds the upper limit number of character ULc, the excess of the number of character determination unit Pde judges that the receiver can not read the input electronic mail to the end, and does not give a permission to send the corresponding electronic mail Me.
