Recipient information is allocated to a transmission box in the image
processing apparatus based on the header information in the e-mail sent
from the external terminal. Scanned image data is stored and linked to
the same transmission box. Subsequently, based on the recipient
information, the image data is sent to the recipient as an attachment to
an e-mail addressed to the recipient. Because the recipient information
and the image data are linked via the transmission box, it is not
necessary to simultaneously designate the recipient and input the image
data. Therefore, the operation panel of the image processing apparatus
need not be occupied for a long period of time.
