Patent US 7,119,919

An image data communication apparatus is connected to an image data source and to a network, and transmits image data attached to an e-mail to a receiving apparatus via the network. The e-mail includes a mail from command and a mail message. The image data is attached to e-mail as an openable document. The image data communication apparatus comprises a memory which stores a mail address of at least one user and a panel section which selects the mail address of at least one user stored in the memory. The image data communication apparatus comprises a controller which sets the mail address of the user selected by the panel section into the mail message of the e-mail to which the image data is attached. Thus, a reply to the e-mail is returned to the mail address of the user.
