A facsimile apparatus is connected to a telephone network and to an
internet network. The facsimile apparatus is capable of receiving E-mail
data via the internet network and transmitting facsimile data to a
facsimile destination via the telephone network. A detector detects a
password indicating an instruction to relay the received E-mail data to
the facsimile destination, and a telephone number of the facsimile
destination, in a mail address of the E-mail data. A generator, when the
detector detects the password and the telephone number, deletes the
password from the mail address, and generates header information including
a mail address after deleting the password. A converter converts the
E-mail data, including the header information, into facsimile data. A
transmitter transmits the converted facsimile data with the header
information, but without the password to the facsimile destination
indicated by the telephone number.
