## Abstract

A destination address of transmission of designated image data attached to e-mail and a notification destination address to be notified of error information if a transmission error occurs are set. If a transmission error occurs due to size excess of the transmitted e-mail, retransmission confirmation information containing the error information and designate input accept information for accepting designate input which designates whether to execute retransmission of the e-mail in which the transmission error has occurred is generated. The generated retransmission confirmation information is notified to a notification destination specified by the set notification destination address.

a retransmission unit adapted to transmit an e-mail attached to image data, whose size is smaller than a size of the image data attached to the e-mail in which the transmission error has occurred, to the transmission destination address set by said setting unit in a case where the reply information is received by said receiving unit; and
a registration unit adapted to register the retransmission confirmation information in an apparatus different from the client apparatus,
wherein the generation unit generates the retransmission confirmation e-mail which contains reference information for referring to the retransmission confirmation information registered by said registration unit.

### Claim 2 (depends on 1)

The apparatus according to claim 1, further comprising a compression unit adapted to generate compressed image data of the image data attached to the e-mail,
wherein said generation unit generates the retransmission confirmation information by a webpage described in a structured page description language, and
the webpage comprises:
the error information;
the image data attached to the e-mail in which the transmission error has occurred;
the compressed image data corresponding to the image data; and
the designate input accept information.

### Claim 3 (depends on 1)

The apparatus according to claim 1, further comprising a compression unit adapted to generate compressed image data of the image data attached to the e-mail,
wherein said compression unit generates thumbnail image data of the image data attached to the e-mail in which the transmission error has occurred, and thumbnail image data of the compressed image data corresponding to the image data,
said generation unit generates e-mail containing the retransmission confirmation information, and
the e-mail comprises:
the error information;
the thumbnail image data of the image data attached to the e-mail in which the transmission error has occurred;
the thumbnail image data of the compressed image data corresponding to the image data; and
the designate input accept information.

### Claim 4 (depends on 1)

The apparatus according to claim 1, further comprising:
a reading unit adapted to read a document; and
an input unit adapted to input image data across a network,
wherein the designated image data comprises one of image data obtained by said reading unit and image data input from said input unit.

### Claim 5 (depends on 1)

The apparatus according to claim 1, wherein said receiving unit receives a reply e-mail containing the reply information in case that the retransmission of the e-mail is requested by the user of the client apparatus in response to a transmission of the retransmission confirmation e-mail.

### Claim 6

A control method of an e-mail transmission apparatus capable of transmitting an e-mail to which image data is attached, comprising:
setting a transmission destination address, and a reply destination address;
transmitting an e-mail, to which image data is attached, to a transmission destination address;
generating retransmission confirmation e-mail related to retransmission confirmation information for making a user of a client apparatus corresponding to the reply destination address to designate a request for a retransmission of the e-mail in which the transmission error has occurred if a transmission error due to size excess of the e-mail transmitted by said e-mail transmitting unit occurs;
transmitting the retransmission confirmation e-mail to the reply destination address;
receiving reply information indicating that the retransmission of the e-mail is requested by the user of the client apparatus in case that the retransmission of the e-mail is requested by the user of the client apparatus in response to a transmission of the retransmission confirmation e-mail; and
transmitting an e-mail attached to image data, whose size is smaller than a size of the image data attached to the e-mail in which the transmission error has occurred, to the transmission destination address in a case where the reply information is received; and
registering the retransmission confirmation information in an apparatus different from the client apparatus,
wherein the generating step generates the retransmission confirmation e-mail which contains reference information for referring to the retransmission confirmation information registered in said registration step.

### Claim 7 (depends on 6)

The control method according to claim 6, further comprising generating compressed image data of the image data attached to the e-mail,
wherein said generating step generates the retransmission confirmation information by a webpage described in a structured page description language, and
the webpage comprises:
the error information;
the image data attached to the e-mail in which the transmission error has occurred;
the compressed image data corresponding to the image data; and
the designate input accept information.

### Claim 8 (depends on 6)

The control method according to claim 6, further comprising generating compressed image data of the image data attached to the e-mail, generating thumbnail image data of the image data attached to the e-mail in which the transmission error has occurred, and generating thumbnail image data of the compressed image data corresponding to the image data,
wherein said generating step generates e-mail containing the retransmission confirmation information, and
the e-mail comprises:
the error information;
the thumbnail image data of the image data attached to the e-mail in which the transmission error has occurred;
the thumbnail image data of the compressed image data corresponding to the image data; and
the designate input accept information.

### Claim 9 (depends on 6)

The control method according to claim 6, further comprising reading a document by a reading unit; and inputting image data across a network by an input unit,
wherein the designated image data comprises one of image data obtained by said reading unit and image data input from said input unit.

### Claim 10 (depends on 6)
