Abstract

PROBLEM TO BE SOLVED: To provide a device/method/program for the transmission control of an electronic mail and a storage medium, which can avoid inappropriate transmission and a reducing checking burden before transmission. SOLUTION: When the check of a transmission permission condition is 'no transmission' (check in a check section 410) when a keyword is included in a transmission document (a transmission document matches with the keyword) as the result of discrimination based on the keyword and a keyword retrieval formula, a prohibition condition is decided to be satisfied if a transmission address is included in a setting list, and the prohibition condition is decided to be not satisfied if the transmission address is not included. On the other hand, when the check is not 'no transmission' (check in a check section 411), a prohibition condition is decided to be satisfied if a transmission destination address is a mail address except for the setting list, and the prohibition condition is decided to be not satisfied if the transmission destination address is not the mail address except for the setting list. When the prohibition condition is not satisfied, the transmission is performed normally but when the condition is satisfied, transmission is prohibited and warning is given.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic mail transmission control apparatus, method, program, and storage medium for transmitting a transmission document to a destination mail address by electronic mail.

[0002]

2. Description of the Related Art With the spread of LANs and the Internet, the number of e-mail users has increased remarkably. In recent years, not only workstations and personal computers, but also various portable terminal devices, and even mobile phones, are equipped with an e-mail function.

In the electronic mail transmission control devices of these devices, a transmission document is created at the time of transmission, a desired destination (mail address) is input, and a simple transmission button on the screen or a button of the device is used. E-mail can be easily sent by sending instructions.

[0004]

However, the above-described electronic mail transmission control device has the following problems.

[0005] That is, if an e-mail is transmitted by clicking a transmission button on a screen or the like, the e-mail is transmitted immediately to the e-mail address of each destination, but input of the destination is inappropriate. The transmission operation may be performed as it is. For example, when there are a plurality of transmission destinations, the transmission destination addresses may include transmission destination addresses for which transmission of the transmission document is inappropriate.

[0006] Depending on the nature of the transmitted document, the document to be transmitted includes a document that the user does not want to be known to a specific person, or a document that the user does not want to be known to other than a specific person. For example, a mistake in setting an e-mail destination for a confidential project may cause fatal damage to the company. In addition, sending a sentence with congratulations to a mourning person by mistake can be very unpleasant. In this way, if an erroneous transmission is made, there is no way to take action even if the user notices later.

In particular, recent e-mails include To, Cc,
Some transmission destinations such as Bcc can be set by simply clicking from a pre-registered address book. In some cases, an address adjacent to the desired address is incorrectly set and sent without confirmation. Although the operability is improved, the risk of sending a transmission document to an inappropriate destination is increasing.

[0008] Although there is e-mail software that can be set to suspend transmission for a predetermined time after giving a transmission instruction, generally there are few users who recheck and send a transmission document to an inappropriate destination without noticing. There are not a few cases where they do.

5). Reference numeral 406 denotes a search formula field for setting a keyword search formula (match determination condition). The keyword search formula defines a search condition when a plurality of keywords are input in the keyword columns 401 to 405.
Conditions using logical expressions such as logical product and logical sum can be set.

"&" Means logical product and "#" means logical sum. For example, keyword columns 401, 402, 40
In the case where a keyword (Key-Word 1, 2, 3) has been entered in 3 and a search expression of “1 & 2 & 3” is set in the search expression column 406, 3 entered in the keyword columns 401, 402, and 403 It is determined whether all of the three keywords (Key-Words 1, 2, and 3) are included in the words in the transmission document. Also, "1
& (2 # 3) "is set in the search expression column 406, at least one of the keywords in the keyword columns 402 and 403 and the keyword in the keyword column 401 are both included in the words in the transmission document. Is determined.

In the present embodiment, as a result of discrimination using a single keyword in the case of a single keyword, and using a search formula in the case of a plurality of keywords, it is determined that a keyword is included in a word in a transmission document by “keyword”. Sent document matches. "
Is expressed as As will be described later, when “the transmission document matches the keyword”, transmission of the transmission document can be prohibited.

Reference numerals 407, 408, and 409 denote a list of mail addresses for which transmission is prohibited or transmission is permitted.
This is an allowed email address setting field, in which at least one email address can be set (hereinafter, “setting list”).
Also referred to as). Reference numerals 410 and 411 are check columns for setting transmission permission / denial conditions, and only one of them can be checked. That is, the check box 410
Is the e-mail address (Address 1, 2, 3) set in the prohibited / permitted e-mail address setting fields 407-409.
Is set as a transmission prohibition target, whereas the check column 411 is used to set e-mail addresses other than those set in the prohibition / permission e-mail address setting columns 407 to 409 as transmission prohibition targets. Is a check column.

For example, when the check box 410 is checked (prohibition condition “0”), the mail addresses set in the prohibited / permitted mail address setting fields 407 to 409 are subject to transmission prohibition. On the other hand, a check box 411
Is checked (prohibition condition "1"), e-mail addresses other than the e-mail addresses set in the prohibition / permission e-mail address setting columns 407-409 are subject to transmission prohibition. As will be described later, whether or not a transmission document is actually prohibited from transmission is determined not only by whether or not the transmission destination mail address is subject to transmission prohibition, but also by determining whether the keyword matches the transmission document as described later. Is also determined.

After all, the “mail transmission prohibition condition” set by the mail transmission prohibition condition setting unit 111 is the keyword column 4
Keywords entered in 01 to 405, search expression column 406
, The set mail address set in the prohibited / permitted mail address setting column 407, and the check contents of the check columns 410 and 411. A combination of these is regarded as one set, and a plurality of sets are set. HD
211 can be stored.

The mail transmission prohibition condition match determination unit 112
As described above, it is determined whether or not the transmitted document satisfies the “e-mail transmission prohibition condition”. In practice, however, a search for a word in the transmitted document is performed based on all combinations of the “e-mail transmission prohibition condition”. After considering the result, the final transmission availability of each transmission document is determined. The “mail transmission prohibition condition” is, for example, read from the HD 211 and read from the RAM 2.
03 is stored. The “mail transmission prohibition condition” is held in the form of an internal table.

FIG. 5 is a diagram showing an example of an internal table of the mail transmission prohibition conditions. In the present embodiment, up to 20 sets of combinations of “mail transmission prohibition conditions” can be registered.

As shown in the figure, as the first set of “mail transmission prohibition conditions”, “XYZ project” is stored in Key-Word 1 and “xyz@aaa.co.j” is stored in Address 1.
"p" is set, and "1" is set as a prohibition condition.
Is set. Since there is one keyword, no keyword search formula is set.

As described above, the prohibition condition “1” corresponds to A
This means that transmission of a document to an e-mail address other than addresses 1 to 3 can be prohibited. Therefore, in the first set of “e-mail transmission prohibition conditions”, for a transmission document including the word “XYZ project”, “xyz@aaa.co.j
The content is prohibited from being sent to e-mail addresses other than "p". The user may set such a combination of “e-mail transmission prohibition conditions” when the user does not want to transmit a transmission document including a certain phrase only to a specific e-mail address.

As a second set of “mail transmission prohibition conditions”,
As shown in the figure, “Dispatch Expenses”, “Alex”, and “Kenny” are set in Key-Words 1, 2, and 3, and “alex@aaa.c” is set in Addresses 1 and 2, respectively.
o.jp "and" kenny@aaa.co.jp "are set. Also, “0” is set as the prohibition condition, and “1 & (2 # 3)” is set as the keyword search formula.

As described above, the prohibition condition “0” indicates that A
This means that document transmission to addresses 1 to 3 can be prohibited. Also, "1 & (2 # 3)" in the keyword search formula
Is at least one of Key-Words 1 and 2 and Key
-Word3 is used as a criterion for determining whether or not any word is included in a word in the transmitted document. Therefore, in the second set of “mail transmission prohibition conditions”, “Alex” and “Ke
"alex@aaa.co.jp" and "kenny @" for sent documents that include at least one of "nny" and "dispatch cost"
aaa.co.jp "is prohibited. Note that “Alex” and “Kenny” in this example are the names of temporary staff, and are set to prohibit the sending of an email related to at least one of the two temporary staff members to one of the two workers by mistake. This is an example. Therefore, the user may set such a combination of “e-mail transmission prohibition conditions” in a case where the user does not want to transmit a transmission document including a certain phrase to a specific e-mail address.

FIG. 6 is a diagram showing a flowchart of the mail transmission processing in the present embodiment. This process is executed by the CPU 201, for example, when an instruction to start transmission of a transmission document is issued. Although this processing is performed for each document to be transmitted, a plurality of documents may be processed collectively when a transmission start instruction is issued. Further, when there are a plurality of combinations of “mail transmission prohibition conditions”, this process is performed for each combination.

First, a mail transmission prohibition condition match determination unit 112 described later with reference to FIG. 7 is executed for a transmission document to be transmitted (step S601). It is determined whether or not the transmission document meets the mail transmission prohibition condition (step S602).

As a result of the determination, if the transmitted document does not meet the mail transmission prohibition condition, a process of transmitting the document normally by the mail transmission process is executed (step S6).
04) On the other hand, if the transmission document satisfies the mail transmission prohibition condition on the other hand, a warning display (predetermined notification) is performed (step S603), and the processing ends. In this case, the transmission processing is not performed on the transmission document. Thereby, inappropriate transmission is avoided in advance, and the user is notified that the transmission destination is inappropriate.

For example, the warning may include a message indicating that the transmission document should not be transmitted to the transmission destination address.
This is done by displaying on the RT 210. However, the mode of the warning is not limited to this, and a warning by voice, a warning by mark display, or the like may be adopted or used in combination. Thereby, the check load before transmission is reduced.

FIG. 7 is a flowchart showing the mail transmission prohibition condition match determination process executed in step S601 in FIG.

First, it is determined whether or not a keyword is included in the transmitted document (determination of matching between the keyword and the transmitted document).
(Step S701). This determination is made based on the keyword entered in the keyword columns 401 to 405 and the search expression column 40.
6 based on the keyword search formula. For example, in the first set illustrated in FIG. 5, when the sent document includes the word “XYZ project”, “YYZ project” is used.
ES ”. In the second group, when “Alex” and “dispatch cost” are included in the transmitted document,
If “Kenny” and “dispatch cost” are included, and if “Kenny”, “Alex” and “dispatch cost” are included, “YES” is determined.

As a result of the determination, if the keyword is included in the transmission document (the transmission document matches the keyword), it is determined whether the check is set to “transmission prohibited” (step S702). This determination is made based on the check in the check boxes 410 and 411 shown in FIG.
If the check box 410 is checked, "YE
S ".

If the result of determination in step S 702 is that “transmission prohibited” is checked, it is determined whether or not the transmission address is included in the setting list (step S 703). This determination is made by comparing the destination mail address with the set mail addresses set in the prohibited / permitted mail address setting columns 407 to 409,
Destination email address ("To", "Cc", "Bc
c) at least one of the e-mail addresses set in the prohibited / permitted e-mail address setting fields 407 to 409 is determined to be "YES".

As a result of the discrimination in step S703, when the transmission address is included in the setting list (in the second set exemplified in FIG. 5, the transmission destination mail address is "alex @
aaa.co.jp "or" kenny@aaa.co.jp ")
Is determined that the destination e-mail address of the sent document is an e-mail address that should not be sent.
It is determined that the prohibition condition matches, that is, it is determined that the transmission document matches the e-mail transmission prohibition condition (step S70).
4), end this processing. In this case, "YES" is determined in the step S602 in FIG. 6, and the transmission of the transmission document is prohibited. For example, the second example illustrated in FIG.
In terms of group, the destination e-mail address is "alex@aaa.co.j
p '', the email address `` alex@aaa.co.
jp "is prohibited.

On the other hand, as a result of the discrimination in step S703, when the transmission address is not included in the setting list (in the case of the second set exemplified in FIG. 5, the transmission destination mail address is "alex@aaa.co.jp ”Or“ kenny＠aaa.co.jp ”
), It is determined that the transmission destination e-mail address of the transmission document does not correspond to the e-mail address for which transmission is prohibited, and therefore, it is determined that the prohibition condition does not match, that is, the transmission of the transmission document is prohibited. It is determined that the condition is not met (step S706), and this processing ends. In this case, "NO" is determined in the step S602 in FIG. 6, and the transmission process is executed normally.

As a result of the determination in step S701, if the keyword is not included in the transmission document (the transmission document does not match the keyword), it is not necessary to prohibit the transmission of the transmission document regardless of the destination mail address. Therefore, it is determined that the prohibition condition does not match, that is, it is determined that the transmitted document does not match the e-mail transmission prohibition condition (step S706), and this processing ends. In this case, "NO" is determined in the step S602 in FIG. 6, and the transmission process is executed normally.

If the result of determination in step S702 is that the check is not "transmission prohibited", it is determined whether or not the destination address is a mail address other than the setting list (step S705). This determination is made based on the destination mail address and the prohibited / permitted mail address setting column 40
This is performed by collating with the set e-mail address set in 7 to 409. In this case, in step S70
3, since the check box 411 is checked, the destination mail address (“To”, “C”
“YES” when at least one of “c” and “Bcc” is a mail address other than the mail addresses set in the prohibited / permitted mail address setting fields 407 to 409.
Is determined.

As a result of the determination in step S705, when the destination address is not a mail address other than the setting list (in the case of the first set illustrated in FIG. 5, the destination address is "xyz@aaa.co.jp" In this case, it is determined that the transmission destination e-mail address of the transmission document does not correspond to the e-mail address that should not be prohibited. Therefore, the prohibition condition does not match, that is, the transmission document satisfies the e-mail transmission prohibition condition. It is determined not to be performed (step S706), and this processing ends. In this case, “NO” in step S602 of FIG.
Is determined, and the transmission process is executed normally.

On the other hand, as a result of the determination in step S705, when the destination address is a mail address other than the setting list (in the first set illustrated in FIG. 5, the destination address is "xyz@aaa.co. jp "), it is determined that the destination e-mail address of the transmitted document corresponds to the e-mail address to which transmission should be prohibited. Therefore, it is determined that the prohibition condition is met. Is determined to match (step S704), and this process ends. In this case, "YES" is determined in the step S602 in FIG. 6, and the transmission of the transmission document is prohibited.

According to the present embodiment, the match determination between the sent document and the keyword, the prohibited / permitted mail address setting column 4
Based on the set e-mail addresses set in 07-409 and the transmission permission / denial conditions by checking the check boxes 410 and 411, it is determined whether each transmission document can be transmitted to the transmission destination e-mail address. When the transmission document matches the keyword and the transmission destination e-mail address falls under the transmission prohibition target, the transmission of the transmission document to the transmission destination e-mail address is prohibited. It is possible to avoid improper transmission due to improper transmission or transmission destination setting error, and to reduce a check load before transmission. Also, a warning is displayed at the same time, so that the user can be notified that the transmission destination is inappropriate.

At this time, since the match between the transmission document and the keyword is determined based on the input keyword and a keyword search formula such as logical product or logical sum, the transmission is prohibited under more detailed conditions. Documents to be selected can be selected, the range of use is widened, and the usability is improved.

Further, since the determination as to whether or not the transmission destination mail address is the transmission prohibition target is made based on the set mail address and the transmission permission / denial condition, there are two cases: It can be used differently depending on whether you do not want to send it only to specific people, and the usability is improved.

Further, since the keyword search formula, the set mail address and the transmission permission / denial condition can be set in any combination, the range of use is expanded and the usability is improved.
