Description

  The present invention relates to an information processing apparatus, a control method for the information processing apparatus, and a program.

  By using electronic mail, it is possible to share information with a large number of partners at once. For e-mail, To set the e-mail address that is the direct recipient of the e-mail, Cc (Carbon copy) to set the e-mail address of the other party you want to send e-mail for reference, and e-mail for reference However, if you do not want other recipients to know your e-mail address or if you do not want to know that you are sending, you can use different Bcc (Blind carbon copy) to set the destination. .

  Also, in Bcc, although it is a direct transmission partner, it is also used when there is no knowledge between the recipients and it is desired that other recipients do not know the mail address (for example, distribution of a mail magazine). As a result, it is possible to prevent information leakage that an e-mail address is known to others.

  However, it is a complicated task to set the transmission destination separately for each, and there are many mistakes that the address to be set to Bcc is set to To or Cc.

  Patent Document 1 aims to provide a technique for reducing a user's mistake in specifying an e-mail destination. When the number of destinations is a predetermined number or more, or when a predetermined address is set as a destination, A technique for converting to Bcc is disclosed.

JP 2007-11431 A

  However, whether to set to To or Cc or to set to Bcc should be set appropriately depending on the contents of the mail and the relationship between recipients. That is, there are cases where it is not appropriate to uniformly convert all transmission destinations to Bcc. In such a case, the addresses to be left in To and Cc and the addresses to be converted to Bcc are appropriately determined. Is required.

  Therefore, an object of the present invention is to provide a mechanism for appropriately setting Bcc in the setting of an electronic mail transmission destination.

  In the present invention, a first condition indicating that a predetermined number or more of destinations are set for an e-mail, and destinations of a plurality of types of domains different from the domain of the e-mail are set for the e-mail. A first determination unit that determines whether or not any one of a plurality of conditions including a second condition indicating that the first condition is satisfied; and the first determination unit satisfies the one of the conditions In the case where it is determined that the e-mail has not been shown to the recipient, the recipient set as the first recipient whose email address is shown to the recipient is the second recipient And setting means for changing the setting to the transmission destination.

  According to the present invention, the destination of the e-mail is set from the first destination (To, Cc) where the mail address is shown to the recipient to the second destination (Bcc) where the mail address is not shown to the recipient. ) Can be changed appropriately. Therefore, it is possible to appropriately set the Bcc in the e-mail transmission destination setting.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. The following embodiments do not limit the invention according to the claims, and all combinations of features described in the embodiments are not necessarily essential to the solution means of the invention.

FIG. 1 is a diagram illustrating the configuration of a system to which an information processing apparatus according to an embodiment of the present invention can be applied.
As shown in FIG. 1, the system of this embodiment includes an information processing apparatus 101, a sender terminal 102, a destination terminal 103, an inspector terminal 105, and the like.
The information processing apparatus 101 is connected to the sender terminal 102 and the inspector terminal 105 via a network 104 such as a LAN or an intranet. Furthermore, the information processing apparatus 101 is connected to the transmission destination terminal 103 via a network 106 such as an Internet line.
The information processing apparatus 101 receives and relays an electronic mail transmitted from the sender terminal 102.

Hereinafter, an example of the hardware configuration of the information processing apparatus 101 illustrated in FIG. 1 will be described with reference to FIG.
FIG. 2 is a diagram illustrating a hardware configuration of the information processing apparatus 101 illustrated in FIG. 1.

  In FIG. 2, reference numeral 201 denotes a CPU that comprehensively controls each device and controller connected to the system bus 204. In addition, the ROM 203 or the external memory 211 realizes a BIOS (Basic Input / Output System) or an operating system program (hereinafter referred to as an OS) that is a control program of the CPU 201 and a function executed by each server or each PC (personal computer). Various programs, data, and the like necessary for the operation are stored.

  A RAM 202 functions as a main memory, work area, and the like for the CPU 201. The CPU 201 implements various operations by loading a program necessary for execution of processing from the ROM 203 or the external memory 211 into the RAM 202 and executing the loaded program.

  An input controller 205 controls input from the input device 209 or the like. A video controller 206 controls display on a display device 210 such as a liquid crystal display. The display device is not limited to a liquid crystal display, and may be another display device such as a CRT display. The input device 209 is, for example, a keyboard, a mouse, or a pointing device such as a touch panel provided on the surface of the display device 210. The display device 210 and the input device 209 are used as necessary.

  A memory controller 207 controls access to the external memory 211. The external memory 211 stores a boot program, various applications, font data, user files, editing files, various data, and the like. The external memory 211 is, for example, a hard disk (HD), a solid state drive (SSD), a flexible disk (FD), or a compact flash (registered trademark) memory connected to the PCMCIA card slot via an adapter. However, other storage devices may be used.

  A communication I / F controller 208 is connected to and communicates with an external device via a network (for example, the network 104 shown in FIG. 1), and executes communication control processing on the network. The communication I / F controller 208 can perform communication using TCP / IP, for example.

  Note that the CPU 201 enables display on the display device 210 by executing outline font rasterization processing on a display information area in the RAM 202, for example. The CPU 201 can accept a user instruction when the user operates a mouse cursor (not shown) displayed on the display device 210 with the input device 209. Further, when the information processing apparatus 101 is accessed from an external apparatus (for example, the inspector terminal 105), the CPU 201 transmits a screen to the external apparatus, and issues an instruction via the screen displayed on the external apparatus from the external apparatus. By receiving it, it is also possible to accept user instructions.

Various programs operating on the hardware of the information processing apparatus 101 are recorded in the external memory 211, and are executed by the CPU 201 by being loaded into the RAM 202 as necessary.
Note that the information processing apparatus 101 is not necessarily provided with all of these configurations, and may be provided with necessary ones.

  Hereinafter, processing executed by the CPU 201 of the information processing apparatus 101 will be described with reference to FIGS. In this process, the information processing apparatus 101 changes the transmission destination set as To and Cc in the e-mail to Bcc when the e-mail satisfies a predetermined condition. Note that the destination set as To, Cc (Carbon copy) is a destination whose e-mail address is indicated to the recipient. A transmission destination set as Bcc (Blind carbon copy) is a transmission destination whose mail address is not indicated to the recipient.

  3 to 5 are flowcharts illustrating processes executed by the CPU 201 of the information processing apparatus 101. The processing shown in this flowchart is implemented by software, and is realized by the CPU 201 of the information processing apparatus 101 reading and executing a program stored in the external memory 211 or the like.

First, the processing of the flowchart of FIG. 3 will be described.
In step S101, when the CPU 201 of the information processing apparatus 101 receives an e-mail transmitted from the sender terminal 102, the process proceeds to step S102.
In step S102, the CPU 201 applies a transmission control rule as shown in FIG. 8 to the electronic mail (hereinafter, processing target electronic mail) received in step S101.

  FIG. 8 is a diagram illustrating an example of a table in which transmission control rules are registered. This table is stored in advance in the external memory 211 of the information processing apparatus 101 or the like.

As shown in FIG. 8, information such as ID 801, condition 802, action 803, and Bcc conversion 804 is registered in the transmission control rule in this embodiment. ID 801 is identification information for uniquely identifying a transmission control rule. A condition 802 indicates a condition to which the transmission control rule is applied. An action 803 indicates an operation when the condition 802 is satisfied. The Bcc conversion 804 indicates whether or not To or Cc is converted to Bcc.
Note that the transmission control rules are not limited to the rules shown in FIG. 8, and may include other rules.

  In this embodiment, the CPU 201 applies the rules by confirming whether or not the transmission control rule with the smaller number indicated by the ID 801 can be applied in order in S102 of FIG. 3, and is set in the rule in S103 and thereafter. The processing based on the action 803 and the Bcc conversion 804 is executed.

The description returns to the flowchart of FIG.
In step S103, the CPU 201 determines whether or not the number of destination addresses of the processing target email is equal to or greater than a predetermined number (a predetermined number or more) based on the result of S102 (ID of transmission control rule). : 1 (determining the result of applying the rule (5 or more destinations)).
If it is determined that the number of destination addresses of the e-mail to be processed is not equal to or greater than the predetermined number (No in S103), the CPU 201 proceeds to step S104. The case of YES in S103 will be described later.

  In step S104, the CPU 201 determines whether or not a plurality of types of external domains are included in the transmission destination of the e-mail to be processed based on the result of the above S102 (transmission control rule ID: 2 rule (external Determine the result of applying multiple domains)). The external domain refers to a domain that is different from the domain of the sender's email address. For example, a predetermined domain such as a group company is treated as an internal domain even if the domain is different from the sender. Also good.

If it is determined that a plurality of types of external domains are not included in the transmission destination of the e-mail to be processed (No in S104), the CPU 201 proceeds to step S105. The case of YES in S104 will be described later.
In step S105, when a rule other than the rules in S103 and S104 is set, the CPU 201 applies the rule and moves the process to step S108.

If it is determined in S103 that the number of destination addresses of the e-mail to be processed is equal to or greater than the predetermined number (YES in S103), the CPU 201 proceeds to step S106.
Also, when it is determined in S104 that a plurality of types of external domains are included in the transmission destination of the processing target e-mail (YES in S104), the CPU 201 shifts the process to step S106.

In step S106, the CPU 201 specifies whether or not Bcc conversion is specified for the rules provided in S103 or S104 (whether or not Bcc conversion is set when the rules in S103 or S104 are applied). Determine whether. Specifically, it is determined whether or not a flag “convert” is set in the Bcc conversion 804 item of the transmission control rule shown in FIG.
If the CPU 201 determines that the Bcc conversion is not specified in the rules provided in S103 and S104 (NO in S106), the CPU 201 proceeds to step S108. The case of YES in S106 will be described later.

In step S108, the CPU 201 determines whether or not the action of the applied rule is “send”. “Sending” refers to a process of sending an e-mail to a destination without being audited by an auditor. If there is no applied rule, it is determined by whether or not the action when no rule is applied is “send” (in this embodiment, the rule of ID: 5 in FIG. 8 corresponds) And “Send” is set for the action).
If it is determined in S108 that the action of the applied rule is “send” (YES in S108), the CPU 201 proceeds to step S111.
In step S111, the CPU 201 transmits the processing target e-mail to the transmission destination, and ends the processing of this flowchart.

On the other hand, if it is determined in S108 that the action of the applied rule is not “send” (NO in S108), the CPU 201 shifts the processing to step S109.
In step S109, the CPU 201 determines whether or not the applied rule action is “pending”. The case where there is no applied rule is the same as S108.

If it is determined that the applied rule action is not “pending” (NO in S109), the process proceeds to step S110. In this embodiment, when the action is neither “send” nor “hold”, the e-mail is deleted.
In step S110, the CPU 201 deletes the processing target e-mail and ends the process of this flowchart.

On the other hand, if it is determined in S109 that the action of the applied rule is “pending” (YES in S109), the CPU 201 proceeds to step S112.
In step S112, the CPU 201 suspends transmission of the processing target e-mail and registers it in a suspend mail list (not shown). It is assumed that the pending mail list is stored in the external memory 211 of the information processing apparatus 101.

  Next, in step S113, the CPU 201 controls to display a hold mail list screen shown in FIG. 6 to be described later based on the hold mail list in accordance with an audit request from the auditor. That is, a list of e-mails registered in the hold mail list is displayed. When the audit request is made from the input unit 205 of the information processing apparatus 101, the CPU 201 displays a pending mail list screen on the display apparatus 210 of the information processing apparatus 101. When the audit request is made from an external device (for example, the inspector terminal 105) via the network 104, the CPU 201 transmits display data of the pending mail list screen to the external device, and displays it on the display unit of the external device. The pending mail list screen is displayed.

  Next, in step S114, when the CPU 201 selects an email to be audited (audit email) from the auditor via the suspended email list screen, the audit email is shown in FIG. Control to display the audit screen shown. The display destination of the audit screen is the same as that of the pending mail list screen shown in FIG. And CPU201 will advance a process to step S115, if the audit result (instruction of transmission permission) of an applicable mail is received via an auditing screen (Drawing 7). The details of the audit process including the audit screen display process of S113 and the audit result reception process of S114 will be described later with reference to FIGS.

  In step S115, the CPU 201 determines whether the audit result received in step S114 is an instruction to permit transmission of an email (“mail transmission” instruction) or an instruction not to permit (“mail deletion” instruction). .

If it is determined that the instruction is a transmission instruction (“transmission” in S115), the CPU 201 proceeds to step S116.
In step S116, the CPU 201 sends the e-mail selected as the audit target in S114 to the transmission destination, and ends the process of this flowchart.

On the other hand, if it is determined that the instruction is not a transmission instruction (“delete” in S115), the CPU 201 shifts the processing to step S117.
In step S117, the CPU 201 deletes the e-mail selected as the audit target in S114 and ends the process of this flowchart.

If it is determined in S106 that Bcc conversion is specified in the rules provided in S103 or S104 (YES in S106), the CPU 201 proceeds to step S107.
In step S107, the CPU 201 stores the Bcc conversion execution instruction in the control file, and shifts the processing to S201 in FIG. It is assumed that the control file is stored in the external memory 211 of the information processing apparatus 101.

Hereinafter, the process of the flowchart shown in FIG. 4 will be described.
In step S201, the CPU 201 obtains a Bcc conversion execution command from the control file described above, and proceeds to step S202.
In step S202, the CPU 201 acquires an address set as Bcc among the transmission destinations set in the processing target e-mail. As for the Bcc address, an address that exists in the envelope To (mail destination information notified by SMTP) and does not exist in the headers To and Cc is acquired as an address set in Bcc.

Next, in step S203, the CPU 201 determines whether or not the address set in Bcc has been acquired as a result of the process in S202, that is, whether or not an address has been set in Bcc.
If it is determined that no address is set in Bcc (NO in S203), the CPU 201 proceeds to step S204. The case of YES in S203 will be described later.

  In step S204, the CPU 201 specifies a name corresponding to the address using the addresses set in To and Cc of the processing target email and the address information shown in FIG. Then, it is confirmed whether the identified name is described in the mail text of the processing target electronic mail.

FIG. 9 is a diagram illustrating an example of a table in which address information is registered. This table is stored in advance in the external memory 211 of the information processing apparatus 101 or the like.
As shown in FIG. 9, information such as ID 901, name 902, and address 903 is registered in the address information. The address information manages the mail address indicated by the address 903 in association with the name (name) indicated by the name 902 of the owner of the mail address. For example, the address information of ID: 1 indicates that the address of “Ito” is “AAA@abc.com”.

  In step S205, the CPU 201 determines whether or not the name of the recipient (transmission destination) exists (is included) in the mail body as a result of the above-described step S204. Note that the name of the person who is the recipient (destination) is often written in the first line or the beginning of the mail text. Therefore, by determining whether the name is included in the first line or the beginning of the mail text, it is possible to increase the accuracy of determining whether the mail is addressed to that person.

  If the CPU 201 determines that the name of the recipient (destination) does not exist (is not included) in the mail body of the processing target email (NO in S205), the CPU 201 proceeds to step S206. To do. The case of YES in S205 will be described later.

In step S206, the CPU 201 converts (changes settings) the addresses of the headers To and Cc set in the processing target e-mail to Bcc.
Next, in step S207, the CPU 201 acquires an address corresponding to the address of the header From (transmission source) using the address setting table shown in FIG. 10. Next, in step S208, the CPU 201 acquires in step S207. The address thus set is set in the header To of the email to be processed, and the process proceeds to the process shown in the flowchart of FIG. That is, since the transmission destination is not set in To of the processing target e-mail due to the setting change in S206, the CPU 201 executes the processing shown in S207 and S208 and performs the processing of the e-mail to be processed. An appropriate address is set in the header To to prevent the processing target electronic mail from being treated as a suspicious mail.

  FIG. 10 is a diagram illustrating an example of a table in which an address setting table is registered. This table is stored in advance in the external memory 211 of the information processing apparatus 101 or the like.

  As shown in FIG. 10, information such as an ID 1001, a sender (From) mail address 1002, and a destination (To) mail address 1003 is registered in the address setting table. With such a configuration, in the address setting table, the mail address 1002 of the transmission source (From) and the mail address 1003 of the transmission destination (To) corresponding to the mail address are managed in association with each other. For example, the mail address “XXX@abc.com” of the transmission destination (To) is set corresponding to the mail address “AAA@abc.com” of the transmission source (From). That is, when the transmission source (From) of the processing target email is “AAA@abc.com”, “XXX@abc.com” is set in the header To of the email in S208 of FIG. .

  The table shown in FIG. 10 may be set in advance by the administrator, or may be set by the superior of the sender in cooperation with personnel information or the like. Further, the sender address may be controlled to be set to To without using such a table.

If it is determined in S205 that the name of the recipient (transmission destination) exists (is included) in the mail body of the processing target e-mail (Yes in S205), the CPU 201 performs the process. The process proceeds to step S209.
In step S209, the CPU 201 converts (changes the setting of) the header To and Cc addresses other than the header To and Cc addresses whose names exist in the mail body of the processing target e-mail to Bcc. Transition to the processing shown.

If it is determined in S203 that the address is set in Bcc as a result of the process in S202 (YES in S203), the CPU 201 proceeds to step S210.
In step S210, the CPU 201 determines whether an address of the same domain as the domain set in the headers To and Cc of the e-mail to be processed is set in Bcc.

If it is determined that the same domain address is not set (NO in S210), the CPU 201 proceeds to step S211.
In step S211, the processing shifts to the process shown in the flowchart of FIG. 5 without converting the addresses To and Cc of the e-mail to be processed into Bcc (setting change).

On the other hand, if it is determined in S210 that the address of the same domain as the address set in the headers To and Cc of the processing target email is set to Bcc (YES in S210), the CPU 201 Shifts the processing to step S212.
In step S212, the addresses of the headers To and Cc in the same domain as the address set in Bcc of the electronic mail to be processed are converted into Bcc (setting change), and the process proceeds to the process shown in the flowchart of FIG. Although not shown, when the transmission destination is not set in To of the processing target email due to the setting change in S212, the CPU 201 executes the processing shown in S207 and S208. And

  In the flowchart of FIG. 4, after step S <b> 202, step S <b> 203 may be skipped and the steps subsequent to step S <b> 204 may be executed.

Hereinafter, the process of the flowchart shown in FIG. 5 will be described.
In step S301, the CPU 201 determines whether or not the action of the rule applied in step S102 in FIG.
If the CPU 201 determines that it is “send” (YES in S301), the CPU 201 proceeds to step S302.
In step S302, the CPU 201 sends an e-mail to be processed to the destination, and ends the process of this flowchart.

On the other hand, when determining that it is not “send” (NO in S301), the CPU 201 shifts the processing to step S303.
In step S303, the CPU 201 determines whether the action of the rule applied in S102 of FIG. 3 is “pending”.

If it is determined that the action of the applied rule is not “pending” (“deletion” in this embodiment) (NO in S303), the process proceeds to step S304. In this embodiment, if the action is neither “send” nor “hold”, the e-mail is deleted.
In step S304, the CPU 201 deletes the processing target e-mail and ends the process of this flowchart.

On the other hand, if it is determined that the action of the rule applied in S102 of FIG. 3 is “pending” (YES in S303), the process proceeds to step S305.
In step S305, the CPU 201 suspends transmission of the processing target email and registers it in a suspended mail list (not shown) (similar to S112 in FIG. 3).
Next, the CPU 201 executes the processes of steps S306 to S310 and ends the process of this flowchart. Steps S306 to S310 are the same as steps S113 to S117 in FIG.

Next, a specific example of the processing of the present invention will be described with reference to FIGS.
FIGS. 11 to 16 are diagrams showing specific examples of e-mails processed in the present invention.
FIG. 11 shows an e-mail from the sender: AAA@abc.com to the destination: BBB@abc.com. FIG. 11A shows a state before the process of the present invention is executed (a state where a transmission destination is set by a sender). FIG. 11B shows a state after the processing of the present invention is executed. 12 to 16 described later, (A) shows the state set by the sender, and (B) shows the set state after executing the processing of the present invention.

  Since the mail shown in FIG. 11 (A) has one transmission destination, it is determined NO in both S103 and S104 in FIG. 3, so the processing of the present invention is executed as shown in FIG. 11 (B). After that, To and Cc are not converted to Bcc.

  FIG. 12 shows mail from the sender: AAA@abc.com to the destinations: BBB@abc.com, CCC@abc.com, DDD@abc.com, EEE@abc.com, FFF@abc.com.

  In this embodiment, as shown in the rules of FIG. 8, when there are five or more destinations, the addresses set in To and Cc are converted to Bcc (determined as YES in S103 and S106 in FIG. 3). Then, the processing of S206 to S208 in FIG. 4 is executed). Since the mail shown in FIG. 12A has five or more destinations, as shown in FIG. 12B, the five addresses set as To as the destinations are set as Bcc (FIG. 4). S206). Further, “XXX@abc.com”, which is an address corresponding to “AAA@abc.com”, is set in To as shown in the address setting table of FIG. 10 (S208 in FIG. 4).

FIG. 13 shows a mail from the sender: AAA@abc.com to the destination: 123@xyz.Com, 987@xxx.com.
In this embodiment, as shown in the rules of FIG. 8, when there are a plurality of types of external domains at the destination, the addresses set in To and Cc are converted to BCc (in S104 and S106 in FIG. 3). It is determined YES and the processing of S206 to S208 in FIG. 4 is executed). Since the mail shown in FIG. 13 (A) has a plurality of types of external domains set as the transmission destination, as shown in FIG. 13 (B), “123@xyz.Com” and “987 @ xxx.com "is set to Bcc (S206 in FIG. 4). Then, “XXX@abc.com” that is an address corresponding to “AAA@abc.com” is set in To as shown in the address setting table of FIG. 10 (S208 of FIG. 4).

FIG. 14 shows a sender: AAA@abc.com to a destination: BBB@abc.com, CCC@abc.com, DDD@abc.com, EEE@abc.com, FFF@abc.com, YYY @ yyy. Indicates an email for com.
In the mail shown in FIG. 14A, “BBB@abc.com, CCC@abc.com, DDD@abc.com, EEE@abc.com, FFF@abc.com” is displayed as To in the destination. Is set to “YYY@yyy.com”.

  In this case, since there are five or more destinations, YES is determined in S103 in FIG. 3 and an address is set in Bcc. Therefore, YES is determined in S203 in FIG. 4 and the address set in To Since the domain of the address and the domain of the address set in Bcc are different, NO is determined in S210 of FIG. Therefore, the Bcc conversion process is not executed (S211), and as shown in FIG. 14B, the setting by the sender is maintained even after the process of the present invention is executed.

  FIG. 15 is a diagram showing emails from the sender: AAA@abc.com to the destinations: BBB@abc.com, XYZ@yyy.com, YYY@yyy.com. Among the transmission destinations, “BBB @ abc.com, XYZ @ yyy.com” is set in To, and “YYY@yyy.com” is set in Bcc.

  In the mail shown in FIG. 15A, since a plurality of types of external domains are set for the destination address, YES is determined in S104 of FIG. 3, and the address is set for Bcc. Therefore, S203 of FIG. Since the domain of the address set in To and the address set in Bcc are “XYZ@yyy.com” and “YYY@yyy.com” are the same domain, It is determined YES in S210. Therefore, as shown in FIG. 15B, “XYZ@yyy.com” in the same domain as the address set in Bcc among the addresses set in To is converted into Bcc (S212).

  FIG. 16 shows an email from the sender: AAA@abc.com to the destination: BBB@abc.com, CCC@abc.com, DDD@abc.com, EEE@abc.com, FFF@abc.com FIG.

Since the mail shown in FIG. 16A has five or more destinations, YES is determined in S103 of FIG. In addition, this mail includes character strings “Sato” and “Tanaka” in the mail body. Of the addresses set as transmission destinations, “BBB@abc.com” is registered as “Sato”, and “CCC@abc.com” is registered as “Tanaka” (FIG. 9).
Therefore, it is determined YES in S205 of FIG. 4, and as shown in FIG. 16B, addresses other than the mail addresses corresponding to “Sato” and “Tanaka” included in the mail text in S209 of FIG. 4 (DDD @ abc.com, EEE@abc.com, FFF@abc.com) are converted to Bcc.

  As described above, when the number of destinations is greater than or equal to a predetermined number, by transmitting the transmission destination address as Bcc, information leakage due to notifying the other party's mail address to the transmission destination (mail recipient) Occurrence can be reduced. For example, if you send a mail with a large number of addresses set as the destination (for example, mailing list distribution or advertisement mail distribution to customers), it will be received if you send it with To or Cc instead of Bcc. Will be able to obtain another person's email address. However, in the present invention, it is possible to prevent such leakage of personal information.

  Even when the number of transmission destinations is small, if a plurality of types of external domains are set for the destinations, it can be said that there is a high possibility that the destinations are not familiar with each other. Therefore, in such a case, it is possible to reduce the risk due to information leakage by transmitting with Bcc as in the present invention.

  Also, if a mail address has already been set for Bcc, it is possible that the sender has made appropriate settings even if a large number of destinations have been set or multiple types of external domains have been set. It is considered that the nature is high. Therefore, when a mail address is set in Bcc by the sender in this way, the setting is respected, and control is performed so that the address set in To or Cc is not converted into Bcc. However, since the possibility of a setting error cannot be denied, if an address in the same domain as the address set in Bcc is set in To or Cc, the address is converted to Bcc.

  Even if the address is not set in Bcc by the sender (when all To and Cc addresses are converted to Bcc), the address of the person whose name is in the mail text must be converted to Bcc. Instead, leave it in To or Cc. That is, among the transmission destinations set as headers To and Cc in the processing target electronic mail, the transmission destinations other than the transmission destination determined to have the corresponding name described in the mail text are changed to Bcc. . This is because if there is a name in the text, it can be said that it is a mail addressed directly to that person, and it can be determined that there is no need to convert it to Bcc.

  Further, when all To and Cc are converted to Bcc, the transmission destination (To) becomes blank. Such a mail with To blank may be set to reject reception, and may be treated as a suspicious mail. Therefore, in such a case, the above-mentioned problem can be solved by controlling the address previously associated with the sender (such as the sender itself or the sender's superior address) to be set to To and transmitted. To solve.
