• determining user identification information to be associated with the received output data or output data generated based on the received output target data from user information stored by a user information storage part by using address information of a sender of the mail data or address information included in transmission destinations of the mail data;
• associating data identification information with the output data and storing them in a data storage part when the user identification information to be associated is not determined from the address information of the sender but is determined from the address information included in the transmission destinations;
• notifying of the data identification information via a network;
• and
• transmitting, via a network, the output data associated with the user identification information or the data identification information received via a network.
