The printing company server 12 is connected with a personal computer (hereinafter referred to as “printing company personal computer”) 20 on the side of the printing company for inputting the contents of orders received and various instructions. The printer 22 is connected.

As shown in FIG. 2, the printing company server 12 has an HDD 30, a CPU 32, a RAM 34, and a ROM 3 as shown in FIG.
6 and an order information file 38, which are connected to each other by a bus 44. The bus 44 has an I / F (A) 40 and an I / F (B) 42.
The I / F (A) 40 is connected to the Internet 14 and the I / F (B) 42 is connected to the printing company personal computer 20.

In the order information file, as shown in FIG. 3, the order I is stored as information regarding the print request from the orderer.
Print contents such as D, address, telephone number, e-mail address, permission of e-mail transmission, name, name 2 ... And others are registered.

The provider server 16 is, as shown in FIG. 4, an HDD 50, a CPU 52, a RAM 54, and a ROM 5.
6 and an account information file 58, which are connected by a bus 60.
An I / F 62 is connected to the bus 60, and an I / F 6
2 is connected to the Internet 14.

The account information file 58 stores account information of clients connected to the Internet 14 via the provider server 16.

Next, the operation of this embodiment will be described.

According to a predetermined instruction from the personal computer 20 of the printing company, it is confirmed whether or not the electronic mail address stored in the order information file 38 exists by the procedure shown in FIG.

In step S10, the order information file 38
To list the order information with email address registration. In step S12, the listed order information is sequentially fetched, and in step S14, the e-mail address of the fetched order information is checked for a predetermined error. The contents of the error include the contents shown in the following table, and whether or not these contents are met is checked by the check software stored in the HDD 30.

[0024]

[Table 1]

In step S16, it is determined whether an error is detected as a result of the error check. If an error is detected, an error flag is set in the order information in step S18, and the process proceeds to step S26. If no error is detected, in step S20, a transmission propriety flag for distinguishing propriety of mail transmission to the destination is set based on the instruction of the customer registered as the order information, and in step S22, Similarly, an address confirmation notification flag is set for distinguishing whether or not to notify the sender of the existence confirmation of the destination e-mail address based on the instruction of the customer registered as the order information.

Here, the transmission propriety flag and the address confirmation notification flag will be described. These flags function as identification flags for partially changing the transmission procedure in the server on the transmission side when transmitting an electronic mail according to a predetermined mail protocol.

[0027]

[Table 2]

As shown in [Table 2], the order information data 4 is used as a flag for transmitting permission and a flag for notifying address confirmation.
Secures a bit frame and stores the lower 2 bits "00"
As the identification display for sending the mail contents to the destination, and set "01"
Is an identification display that does not send the mail contents to the destination. Further, the upper 2 bits "01" is used as an identification display for notifying the sender of an address confirmation, and "00" is used as an identification display for not sending an address confirmation to the sender.

In step S24, a mail is sent to the electronic mail address of the fetched order information. In step S26, it is determined whether the data is the last data, that is, whether all the listed data have been processed. If it is not the last data, the process returns to step S12 and the above process is repeated. If it is the last data, this processing ends.

According to the electronic mail address confirmation processing of the present embodiment, by checking whether or not an error occurs in the electronic mail address registered in advance, it is possible to confirm the electronic mail address registered as the print content. You can find mistakes.

Since the e-mail is transmitted by setting the transmission permission flag and the address confirmation notification flag based on the instruction from the orderer, the existence confirmation of the destination is confirmed in the communication with the provider server which manages the destination user. It is possible to identify the e-mail to be sent only and not to forward the e-mail to the destination, and confirm the destination of the e-mail.

Next, confirmation of the domain name of the electronic mail address will be described.

When the address confirmation notification flag is "01", the domain confirmation processing shown in FIG. 6 is performed.

The relevant domain name system server is accessed in step S30, and the domain name of the destination address is transmitted in step S32. Step S34
Then, the process waits until there is a domain name existence confirmation response from the domain name system server, and if there is a response, the response content is stored in the HDD 30 in step S36. Then, in step S40, the connection with the domain name system server is disconnected, and this processing ends.

According to this process, it is possible to easily confirm the presence or absence of the domain name by accessing the domain name system server.

When the destination domain name is confirmed, the electronic mail transmitted from the printing company server 12 is received by the provider server 16 corresponding to the destination domain name via the Internet 14. Different communication is performed between the provider server 16 and the printing company server 12 depending on the setting of the transmission permission flag and the address confirmation notification flag.

First, when the transmission permission / prohibition flag and the address confirmation notification flag are "0000" or "010".
In the case of "0", the contents of the mail are transmitted to the destination, so that normal communication at the time of electronic mail is performed. Then, "01
In the case of "00", since the address confirmation notice is sent to the sender, the printing company server 12 sends O after sending the destination address.
When the K response is received, it is stored that the existence confirmation of the electronic mail address is OK, and when the NG response is received, it is stored that the existence confirmation of the electronic mail address is NG.

When the transmission permission / prohibition flag and the address confirmation notification flag are "0001" or "0101", the mail contents are not transmitted to the destination, and therefore the communication is performed in the procedure shown in FIG.

Then, a connection request is made from the printing company server 12, and the provider server 16 makes a preparation for the connection request, and then a preparation OK response is made. Then, the print server 12 sends its domain name, and the provider server 16 checks the domain name and sends an OK response. The printing company server 12 sends the sender's address in the email, and the provider server 1 sends
6 returns an OK response indicating that the sender address has been received. Then, the printing company server 12 sends the destination address, that is,
Send the printout address of the orderer. The provider server 16 that has received the destination address confirms whether or not the corresponding destination address is registered in the account information file 58, and if it is registered, sends back a response of the destination address OK with, and is not registered. In this case, the response of the destination address NG is returned. When the address confirmation notification flag is “0101”, the printing company server 12 that has received the reply sends the address confirmation notification to the sender, and thus stores the result of the existence confirmation of the e-mail address. Then, a connection disconnection request is made, and if an OK response is received at (10), the connection between the printing company server 12 and the provider server 16 is disconnected at (11) and the communication ends.

As described above, different communication processing is performed in correspondence with the setting of the send permission / prohibition flag and the address confirmation notification flag, so that only the presence or absence of the email address is confirmed without sending the email to the destination. can do.

The confirmation result of the electronic mail address is displayed on the display unit of the printing company personal computer 20, as shown in FIG. 8, for example. Here, an image of a block copy of the print content based on the orderer information is shown. "Email address error" is displayed outside the frame, indicating that the email address is incorrect. Although only "mail address error" is displayed here, it is also possible to simultaneously display error contents such as the absence of a provider and the absence of a user.

Further, FIG. 9 is a screen copy correction screen. As shown in FIG. 9, the electronic mail address portion is displayed in reverse video in the copy with the mail address error, and the electronic mail address can be corrected from this screen.

As described above, by returning the result of the confirmation of the electronic mail address to the order information and correcting the electronic mail address in which the error is confirmed before printing, it is possible to create a highly accurate printed matter. .

[0044]

As described above, according to the first and second aspects of the invention, the user confirmation response from the destination mail server indicating whether or not the destination address exists is received and the response content is stored. , It is possible to confirm the existence of the destination address. Further, since the connection with the destination mail server is disconnected without sending the text, it is possible to avoid sending the mail to the destination by a simple method.

Also, According to the third invention and the fourth invention, when the electronic mail is transmitted, the domain name system server is accessed to check whether the domain of the destination address of the electronic mail exists and store the confirmation result. You can also check if the domain name exists by a simple method.
