storing the history information about said transmitted electronic mail again in another part of said send/receive history information table if the delivery confirmation mail by MDN corresponding to the transmitted electronic mail is received after the communication management report is outputted by said network facsimile device; and including the history information about the transmitted electronic mail and the corresponding delivery confirmation mail by MDN together in the communication management report. ### Claim 49 (depends on 47) The method for controlling the network facsimile device as claimed in claim 47, further comprising the step of displaying a time and a date of receiving the delivery confirmation mail by MDN in the communication management report. ### Claim 50 (depends on 47) The method as claimed in claim 47, wherein an input pointer and an output pointer are used for inputting information to and outputting information from the send/receive history information table, and when the network facsimile device receives the delivery confirmation mail, the management information of the transmitted electronic mail corresponding to the delivery confirmation mail is stored in the send/receive history information table at a location pointed to by the input pointer. ### Claim 51 A method for controlling a network facsimile device comprising the steps of: exchanging image information using an electronic mail by connecting to the Internet; creating a send/receive history information table about the electronic mail and storing management information concerning communications performed by the network facsimile device in an order of occurrences thereof; outputting visibly a communication management report that displays contents of the send/receive history information table as a list; requesting a mail delivery confirmation by DSN when transmitting the image information using the electronic mail; displaying a content that relates delivery confirmation mail by DSN and transmitted electronic mail corresponding to the delivery confirmation mail by DSN to a field wherein the delivery confirmation mail by DSN is displayed, and to a field wherein the transmitted electronic mail is displayed, when the delivery confirmation mail by DSN is received by said network facsimile device; outputting visually the management information stored in the send/receive history information table, when a number of sets of the management information stored in the send/receive history information table reaches a predetermined amount; and storing the management information of the transmitted electronic mail corresponding to the delivery confirmation mail again in the send/receive history information table, when the communication terminal device receives the delivery confirmation mail, in a case where the management information of the transmitted electronic mail has already been output therefrom. ### Claim 52 (depends on 51) The method for controlling the network facsimile device as claimed in claim 51, further comprising the steps of: creating the communication management report based on a part of information on said send/receive history information table, which information includes history information about the transmitted electronic mail; storing the history information about said transmitted electronic mail again in another part of said send/receive history information table if the delivery confirmation mail by DSN corresponding to the transmitted electronic mail is received after the communication management report is outputted by said network facsimile device; and including the history information about the transmitted electronic mail and the corresponding delivery confirmation mail by DSN together in the communication management report. ### Claim 53 (depends on 51) The method for controlling the network facsimile device as claimed in claim 51, further comprising the step of displaying a time and a date of receiving the delivery confirmation mail by DSN in the communication management report. ### Claim 54 (depends on 51) The method as claimed in claim 51, wherein an input pointer and an output pointer are used for inputting information to and outputting information from the send/receive history information table, and when the network facsimile device receives the delivery confirmation mail, the management information of the transmitted electronic mail corresponding to the delivery confirmation mail is stored in the send/receive history information table at a location pointed to by the input pointer. ### Claim 55 A communication terminal device that transmits electronic mail through a network by a mail system thereon, said communication terminal device comprising: a delivery confirmation mail detecting unit that detects delivery confirmation mail corresponding to the electronic mail transmitted by the mail system, said delivery confirmation mail being returned from the mail system on the network; an error mail detecting unit that detects error mail corresponding to the electronic mail transmitted by the mail system, said error mail being returned from the mail system; a memory storing communication management information related to an electronic mail transmission execute by the mail system, said communication management information including a communication result of the electronic mail transmission, said memory also storing a send/receive history information table containing management information concerning communications performed by said communication terminal device in an order of occurrences thereof, the thus-stored management information, not yet output, being output therefrom when a number of sets of the management information stored therein reaches a predetermined amount; a communication result adding unit that adds information indicating a communication success as the communication result to the communication management information, if said delivery confirmation mail detecting unit detects the delivery confirmation mail, and adds information indicating a communication failure as the communication result to the communication management information, if said error mail detecting unit detects the error mail, wherein when said communication terminal device receives the delivery confirmation mail, management information of the transmitted electronic mail corresponding to the delivery confirmation mail is stored again in the send/receive history information table in a case where the management information of the transmitted electronic mail has already been output therefrom. ### Claim 56 (depends on 55) The communication terminal device as claimed in claim 55, wherein an input pointer and an output pointer are used for inputting information to and outputting information from the send/receive history information table, and when the communication terminal device receives the delivery confirmation mail, the management information of the transmitted electronic mail corresponding to the delivery confirmation mail is stored in the send/receive history information table at a location pointed to by the input pointer.
