Patent US 10,185,528

To provide an e-mail communication apparatus, an e-mail communication method and a program capable of, in the case of receiving e-mail which is split e-mails including request-to-send (RTS) information for transmitting the e-mail to a predetermined destination, suitably performing transmittal confirmation without transmitting to a source the e-mail of the transmittal confirmation as to each of multiple pieces of the split e-mails. First, an MFP 100 having received the e-mail determines whether or not the e-mail is one of multiple divided data pieces generated by dividing image data by a data amount so as to store it. In the case where the received data is the divided data, the MFP 100 determines whether or not all the divided data pieces of the image data are stored, and transmits transmittal confirmation mail based on an MDN request if all are stored.
