Problems to be solved by the invention

[0005] By the way, in recent years, there have been examples in which a plurality of mailers from different vendors are installed and used in one computer (mobile phone, PDA device, PC). For example, if a mailer used for business communication is specified by his / her work place or a mailer used for business communication is specified by a customer in order to prevent secret leakage, the user shall Install the mailer on your mail client device (eg mobile phone) May be used.

[0006] In such a case, when a user confirms a received mail of a family member or a friend, he or she activates a personal mailer in his mail client device and receives a mail of business communication from the workplace. In order to confirm the mail, it is necessary to activate the mailer designated by the company, and to activate the mailer designated by the customer power in order to confirm the received mail of the transaction contact from the customer.

[0007] However, it takes a lot of time and effort to check the received mail that is saved in the receiving folder by starting multiple mailers separately. There was a problem. For this reason, the developer has proposed that a technology can be developed that can check the received mail in each receiving folder at once, even if multiple mailers from different vendors are used.

[0008] The present invention has been made in view of the above-described proposal, and the problem is that when a plurality of mailers from different vendors are installed in one computer, each mailer is individually handled. The purpose is to be able to check the contents of the received mail stored in each mailer's receiving folder at one time without starting.

Means for solving the problem

[0009] A received mail display program invented to solve the above problems stores a computer, and for each of one or more mailers, stores received mail that the mailer has received through the mail server as well as other mailer capabilities. Receiving folder location information indicating the location of the receiving folder to be stored in the storage device, when a predetermined instruction is received through the storage means and the input device, each of the reception folder location information in the storage device is received. Receiving mail reading means for reading transmission / reception related information included in the header part of all received mail in the receiving folder at the location indicated by the received folder location information, and transmission / reception related read by the received mail reading means A display device that displays on the display device a list screen containing a list of information that is listed for each received email. It is characterized by functioning as a stage.

[0010] When the received mail display program configured as described above is operated on a computer, an operator of the computer simply inputs a predetermined instruction through the input device. Send / receive related information of all received mail stored in the receiving folders of several mailers can be displayed in a list on the display device.

The invention's effect

[0011] Therefore, according to the present invention, when a plurality of mailers from different vendors are installed on one computer, each mailer is stored in the reception folder of each mailer without starting each mailer separately. You can check the contents of the received mail at once.

Cancel button and power for included. When the mailer registration button is clicked, the CPU 30a starts the mailer information registration program 34b to start the mailer information registration process. When the received mail display button is clicked, the CPU 30a receives the received mail. Starts the display program 34c and starts the received mail display process! /.

FIG. 4 is a diagram showing a flow of mailer information registration processing.

[0038] After the mailer information registration process is started, the CPU 30a executes a process of displaying a mailer information registration screen on the display device 30c (step S101).

FIG. 5 is a view showing an example of the mailer information registration screen 41.

[0040] The mailer information registration screen 41 shown in FIG. 5 includes five text boxes 41a to 41e, an OK button 41f, and a cancel button 41g. 5 text boxes 41a ~ 41e is information on the path where the executable file of the mailer whose information is to be registered, the information on the path where the mailer uses the receiving folder, and the IP address of the server function for local communication set in the mailer. This is a text box for entering the user ID and password required to access the IP address. The OK button 41f is a button for clicking the operator when registering the mailer using the information entered in the text boxes 41a to 41e, and the cancel button 41g is for registering the mailer. A button for the operator to click to cancel.

[0041] After displaying the mailer information registration screen 41 as shown in FIG. 5 on the display device 30c, the CPU 30a waits until one of the buttons 41f and 41g is clicked (step S102; N

0). When any button is clicked (step S102; YES), the CPU 30a determines whether or not the clicked button is the OK button 41f (step S103).

[0042] When the clicked button is the OK button 41f (step S103; YES), the CPU 30a records the record having the information power that has been input in each of the text boxes 41a to 41e at the time of the click, When it is added to the mailer information management table 34a (step S 10 4) and the mailer information registration process shown in FIG. 4 is terminated and the clicked button is the cancel button 41g (step S103; NO), nothing is done. The mailer information registration process shown in Fig. 4 is terminated.

By this mailer information registration process, information about the mailer used in the mail client device 30 can be registered in advance.

6 and 7 are diagrams showing the flow of received mail display processing.

After starting the received mail display process, the CPU 30a reads one unprocessed record from the mailer information management table 34a as shown in FIG. 3 as a processing target (Step S2

01) After that, the collection mail collection process is executed (step S202).

FIG. 8 is a diagram showing the flow of the collection mail collection process.

[0047] After the collection mail collection process is started, the CPU 30a accesses the IP address included in the processing target record (step S301), and then locally uses the user ID and password included in the processing target record. Log in to the communication server (step S3

02). [0048] Then, the CPU 30a determines whether or not an unreceived electronic mail is kept in the mailbox through the server (step S303).

[0049] When an unreceived e-mail is kept in the mailbox! /, (Step S3

03; YES), the CPU 30a collects the stored received mail (step S30).

4) The received mail is stored in the received folder at the location indicated by the path information included in the processing target record (step S305), and the process of logging off from the server is performed (step S306).

[0050] On the other hand, if an unreceived e-mail has been kept in the mailbox! / (No) (step S303; NO), the CPU 30a performs processing to log off from the server without collecting the received mail. (Step S306).

[0051] After logging off from the server, the CPU 30 ends the collected mail collection process according to Fig. 8 and executes the received mail reading process loop L1 of Fig. 6.

[0052] In the received mail read processing loop L1, the CPU 30a receives the data while specifying the received mail data in the receiving folder at the location indicated by the path information included in the processing target record one by one as the processing target. Steps S211 to S214 are executed for each mail data.

[0053] First, in step S211, the CPU 30a reads the subject, reception time, sender and recipient email addresses as transmission / reception related information from the header part of the received email data to be processed in the reception folder. Store in DRAM30b.

In the next step S212, the CPU 30a executes an encryption determination process.

FIG. 9 is a diagram showing the flow of the encryption determination process.

[0056] After starting the encryption determination process, the CPU 30a determines whether or not the header portion in the received mail data to be processed includes information indicating that it is an encrypted mail ( Step S401).

[0057] When the information indicating that it is an encrypted mail is included in the header part (step S401; YES), the CPU 30a converts the encryption flag flag information in the on state into the transmission / reception related information. Correspondingly stored in DRAM 30b (step S402), if the information indicating that it is an encrypted mail is not included in the header part (step S401; NO), an off-state State encryption flag information is stored in the DRAM 30b in association with the transmission / reception related information (step S403).

After adding the encryption key flag information to the transmission / reception related information, the CPU 30a ends the encryption determination process in FIG. 9, and proceeds to step S213 in FIG.

In step S213, the CPU 30a stores the mailer storage path information included in the processing target record in the DRAM 30b in association with the transmission / reception related information.

In the next step S214, the CPU 30a records a record made up of each piece of information stored in the DRAM 30b on the work table.

FIG. 10 is a view showing an example of the data structure of the work table 42.

Each record of the work table 42 in FIG. 10 includes fields of “subject”, “reception time”, “sender”, “recipient”, “mailer storage path”, and “encryption flag”. Have.

[0063] The “Subject”, “Receive time”, “Sender” and “Recipient” fields are fields in which the subject, reception time, sender and recipient e-mail addresses are recorded. It is. The “mailer storage path” field is a field in which the mailer storage path information added to the received mail data to be processed in step S213 is recorded. The “encryption flag” field is a field in which the encryption flag information added to the received mail data to be processed in step S212 is recorded.

[0064] By executing such steps S211 to S214 one by one on the received mail data in the receiving folder at the location indicated by the path information included in the processing target record, Will be output to work table 42.

[0065] After completing steps S211 to S214 for all received mails in this received folder, CPU 30a exits received mail read processing loop L1 and determines whether or not there is an unprocessed mailer. Is determined (step S221 in FIG. 6).

[0066] Then, in the mailer information management table 34a as shown in FIG. 3, the stored mail collection process (step S202) and the received mail reading process loop L1 are executed, and there is a mailer record. If so (step S221; NO), the CPU 30a identifies another unprocessed record as the processing target (step S201), and the identified record With regard to, the retained mail collection process (step S202) and the received mail reading process loop L1 are executed.

[0067] Therefore, in steps S201, S202, LI, and S221, the received mail power work table in the received folders of all mailers 31 to 33 registered in the mailer information management table 34a as shown in FIG. Will be output to 42. Note that these steps S201, S202, LI, and S221 function as the received mail reading means described above.

[0068] Then, when the placement mail collection process (step S202) and the received mail read process loop L1 have been executed for all the records in the mailer information management table 34a (step S221; YES), the CPU 30a Based on the contents of the work table 42 as shown in FIG. 10, a process of displaying the received mail list display screen on the display device 30c is executed (step S222).

FIG. 11 is a diagram showing an example of the received mail list display screen 43.

The received mail list display screen 43 in FIG. 11 includes a received mail list 43a and a close button 43b. The received mail list 43a is registered in the mailer information management table 34a and is stored in each mailer's receiving folder, and has the same number of lines as the received mail. It has columns for “Reception time”, “From”, “Recipient”, “Mailer”, and “Cryptography”. This received mail list 43a is created based on the contents of the work table 42 as shown in FIG. However, a key mark is displayed in the “encryption” column only when the received data is encrypted mail (when the encryption flag is on). Also, if the sender's email address is registered with the mailer in association with the person's name or company name, the sender's name or company name is displayed in the “From” field based on the mailer's registration information. It can be displayed directly. In addition, a mark such as a mailer or a vendor's trademark may be displayed in the “mailer” column. In this case, the area power indicated by the mark may function as the mailer activation button. Each line of this received mail list 43a also functions as a button (starting means) for the user to click to save the received mail in the received folder and start the mailer. Get ready! The close button 43b is used by the user to close the received mail list display screen 43. Button.

[0071] Since this received mail list display screen 43 is configured as shown in Fig. 11, the process of displaying this received mail list display screen 43 on the display device 30c (step S222) is as described above. It functions as a storage means.

[0072] After displaying the received mail list display screen 43 as shown in FIG. 11 on the display device 30c, the CPU 30a waits until any row of the received mail list table 43a or the close button 43b is clicked. (Step S223; NO). When any one is clicked (step S223; YES), the CPU 30a determines whether the click is on any row of the received mail list 43a (step S224).

[0073] Then, if any of the rows in the received mail list 43a is clicked (step S224; YES), the CPU 30a is selected from the screen data of the received mail list display screen 43. The mailer storage path information associated with the specified line is read, the mailer executable file at the location indicated by the mailer storage path information is read, and the mailer activation process is executed (step S225). . After executing this process, the CPU 30a ends the received mail list display process according to FIGS.

On the other hand, if the close button 43b was clicked (step S224; NO), the CPU 30a does not perform any processing and ends the received mail list display processing according to FIGS. 6 and 7. .

Next, the operation and effect of the received mail list software 34 according to the present embodiment will be described.

[0076] When a mailer to be used is specified by a company or customer who has a certain social relationship with the user for reasons such as prevention of secret leakage, the user selects the plurality of mailers. I need to install it on my mail client device 30! /.

[0077] In such a case, each time a user installs a new mailer in the mail client device 30, the user causes the mailer information registration process of FIG. 4 to be executed, and information related to that mailer is as shown in FIG. The mailer information management table 34a is registered (steps S101 to S104).

[0078] Then, the mailer receiving file whose information is registered in the mailer information management table 34a is received. When listing all received mails stored in the orderer, the received mail list display process shown in FIGS. 6 and 7 is executed.

[0079] Then, the process of collecting the received mail that has not been stored in the receiving folder but has arrived at the mail server device 10 mailbox and stores it in the receiving folder, and the reception in the receiving folder Processing power to output mail data to worktable 42 as shown in Fig. 10 All registered mailers are processed sequentially (steps S 201, S202, LI, S221), and then the received mail list as shown in Fig. 11 The display screen 43 is displayed on the force display device 30c (step S222).

[0080] By operating in this way, the user does not activate each of the mailers 31 to 33 one by one, but through the received mail list display screen 43, all mailers 31 to 33 can be used. You will be able to list all incoming mail in the receiving folder at once.

[0081] Further, as described above, the process of automatically collecting the received mail stored in the mailbox of the mail server device 10 and storing it in the receiving folder of the corresponding mailer is automatically performed. (Step S202), the user does not have to take the trouble of starting up the mailer and instructing execution of the collection process for each of the mailers 31 to 33.

[0082] Furthermore, in the received mail list table 43a of the received mail list display screen 43, the encrypted received mail row shows a key mark, so that the user can receive the received mail through the key mark. It is possible to instantly determine whether or not the power is encrypted mail.

[0083] In addition, in the received mail list 43a of the received mail list display screen 43, each line functions as a button for starting a mailer corresponding to the received mail. Thus, it is not necessary to close the received mail list software 34 and start a mailer that can cope with power.

[0084] However, when the mailer corresponding to the received mail can be activated from the received mail list 43a, the received mail list 43a is displayed with a key mark on a plurality of lines. In this case, the user does not have to perform a task of finding and starting a mailer for performing decryption.
