In the mail reply history 301, information on electronic mail related to the mail ID acquired from the reply source mail ID 203 of the mail information 201 is written in a list. With reference to the mail information 201, “M2” is acquired as the data of the reply source mail ID 203, an electronic mail whose mail ID 202 is “M2” is searched from the mail history 126 and written in the mail reply history 303. With reference to the mail reply history 303, “M1” is acquired as the data of the reply source mail ID 203, a mail whose mail ID 202 is “M1” is searched from the mail history 126 and written in the mail reply history 302. With reference to the mail reply history 302, “None” is acquired as the data of the reply mail ID 203, and this mail is determined to be a new mail. The mail ID 202 is referred to from the data of the mail reply history 302, “M1” is obtained, and in order to search for this reply mail, the mail whose reply source mail ID 203 is “M1” is searched from the mail history 126. FIG. 3 shows an example in which the mail reply history 303 is one for the mail with the reply source mail ID 203 of “M1”.

  The mail ID 202 is referred to from the data of the mail reply history 303, “M2” is acquired, and the electronic mail whose reply source mail ID 203 is “M2” is searched from the mail history 126. FIG. 3 shows an example in which the email reply history 304 is one for an email whose reply source email ID 203 is “M2”. The mail ID 202 is referenced from the data of the mail reply history 304, “M3” is acquired, and the mail whose reply source mail ID 203 is “M3” is searched from the mail history 126. FIG. 3 shows that there is no mail with the reply source mail ID 203 of “M3”.

Data whose destination ID 205 of the mail reply history 303 is “A2” is searched from the mail history 126, and the acquired data is written in the destination information history 305. Data whose destination ID 205 of the mail reply history 304 is “A3” is searched from the mail history 126, and the acquired data is written in the destination information history 309.

FIG. 4 shows an example of information acquired from the organization change history.
A user ID 402 is a unique ID for identifying a user whose organization is changed, and is registered in the directory server 123.

  The organization change date 403 is a date when the belonging organization is changed and is registered in the directory server 123. The pre-change organization ID 404 is a unique ID for identifying the organization that belonged before the change due to the change of the belonging organization, and is registered in the directory server 123. The post-change organization ID 405 is a unique ID for identifying the organization to which the post-change organization belongs after the change of the post-change organization, and is registered in the directory server 123.

  The organization name before change 406 is the name of the organization that belonged before the change due to the change of organization, and is registered in the directory server 123. The changed organization name 407 is the name of the organization to which the organization belongs after the change of the organization to which the organization belongs, and is registered in the directory server 123. The post-change job title 408 is registered in the directory server 123 with the name of the post-change job title. The post-change post 409 is registered in the directory server 123 with the post-change post name due to the change of organization.

The organization change history 401 is written as follows.
When it is determined that the data “S2” of the organization ID 210 of the destination information 213 and the data “S1” of the organization ID 210 of the destination information history 306 do not match, the data “2000/1/2” of the transmission date 204 of the mail reply history 303 To get. Since the destination information 213 is registered for confirming the destination, “2000/1/4” is acquired as the date when the destination is confirmed.

  The directory server 123 searches the data “U1” of the user ID 402 and the data “2000/1/2” to “2000/1/4” of the organization change date 403 and writes the acquired data to the organization change history 401. . The directory server 123 searches for the data “2000/1/3” for the organization change date 403, the data “S1” for the organization ID 404 before change, and the data “S2” for the organization ID 405 after change.

  The organization change history 401 shows data of an example in which one user is searched with the organization change date 403 “2000/1/3”, the pre-change organization ID 404 “S1”, and the post-change organization ID 405 “S2”. The organization change history 411 shows data of an example in which the number of users searched by the organization change date 403 is “1999/1/1”, the organization ID 404 before change is “S5”, and the organization ID 405 after change is “S1”.

  The organization information determination result 117 is stored for each user designated as the destination with the degree of the belonging organization as a numerical value. This holds the total value of the scores that fit in the organization change scoring table 501 shown in FIG. 5 and the organization information change scoring table 601 shown in FIG.

  FIG. 5 shows an example of the organization change scoring table 501 definition. As shown in the description of FIG. 8, the specific usage method is a definition table for scoring on the same day based on the number of users whose organization ID before change and organization ID after change are the same. This is a table having the number 502 and the number 503 of users having the same rear organization ID.

  FIG. 6 shows a scoring table 601 for changing organization information. As shown in the description of FIG. 8, the specific usage method is a table for scoring based on the changed part of the organization information, and has the changed part 602 and the score 603 of the organization information. In this example, there are a score 604 corresponding to the organization ID, a score 605 corresponding to the organization name, and a score 606 corresponding to the job title.

  The degree-of-relevance determination result 118 is one that holds, for each user specified as the destination, the degree of relation (the degree of irrelevance / the degree of estrangement) with the mail to be sent as a numerical value. That is, for each series of emails, it is checked whether the destination is designated or not, and a value obtained by adding up the scoring results shown in FIG.

  FIG. 7 shows an example of definitions used when scoring the destination designation status from the mail history. As shown in the explanation of FIG. 8, the specific usage method is a table for scoring according to whether or not it is used for the destination of a series of emails after the organization information change date. It has destination confirmation 702 and scoring (every case) 703. In this example, as indicated by 704, the designation is defined as “minus 5 points” when the destination is designated, and as designated by 705, “10 points” is designated when the destination is not designated.

  The unsealed state determination result 119 is one that holds, for each user designated as the destination, the degree of relationship (degree of irrelevant / distantness) with the mail to be transmitted as a numerical value. Change the value depending on whether it is opened or unopened for a series of emails and keep it. The more unopened mail, the higher the score, and the more unopened mail, the higher the score.

FIG. 8 is an example of a flow showing processing for deleting a user designated as a destination.
First, in step S801, the mail information setting unit 106 acquires information from the directory server 123, and creates destination information 207 as organization information of the user specified as the destination.
Next, in step S <b> 802, the series of mail history acquisition unit 107 searches the mail history 126 and creates a mail reply history 301, destination information history 305, and destination information history 309.
Next, in step S803, a series of mail information is acquired, and in step S804, the reply source mail is traced to the end, and it is confirmed whether there is a change in the organization information of the user designated as the destination.

  For example, in S804, the data “U1” of the user ID 209 in the destination information 213 is confirmed as follows. By referring to the data “M2” of the reply source mail ID 203 of the mail information 206, the data “M2” of the mail ID 202 is confirmed. The mail ID 202 of the mail reply history 303 detects the data “M2”. The history of the destination information of the data “A2” of the destination ID 205 in the mail reply history 303 is confirmed. Since the destination ID 208 of the destination information history 305 is data “A2”, it is confirmed. In the destination information history 305, since the data of the user ID 209 is “U1”, the data of the destination information 207 is compared with the organization information. Since the data “S2” of the organization ID 210 of the destination information 207 and the data “S1” of the organization ID 210 of the destination information history 306 do not match, it is processed that there is a change.

  In S804, if the data of the organization ID 210, the organization name 211, and the post 212 match, it is determined that there is no change in the organization information, and the reply mail is traced to confirm the change of the organization. If the reply mail is traced to the end as in the reply mail history 302 and there is no change in the organization information, it is determined that there is no change.

  Next, in step S805, the score corresponding to each of the organization change scoring table 501 and the organization information change scoring table 601 is acquired.

  For example, the organization change history 401 is organization change history data corresponding to the data “U1” of the user ID 209 in the destination information 213. Since the organization change history 401 is for one person, the number 20 of users with the same organization ID before change and organization ID after change on the same day obtains the data 20 of the score 503 in the organization change scoring table 504, and the organization information determination result Data 20 is written to 117.

  Since the data “S1” of the organization ID 404 before the change in the organization change history 410 and the data S2 of the organization ID 405 after the change do not match, the data 20 of the score 603 in the scoring table 601 of the organization information change is acquired, and the organization information determination result 117 In addition, the data 40 is written.

  Since the data general affairs of the organization name 406 before the change in the organization change history 410 and the data accounting data of the organization name 407 after the change do not match, the data 0 of the score 603 in the scoring table 605 of the change of the organization information is acquired, and the organization information determination In addition to the result 117, the data 40 is written.

  Since the post-change post 408 and post-change post 409 in the organization change history 410 match, the data of the score 603 in the change table 606 for changing the organization information is not referred to.

  In step S806, the relationship between the user whose organization has been changed and the series of emails is scored. Specifically, referring to the organization change history 410, the data “U1” of the user ID 402 and the data “2000/1/3” of the organization change date 403 are acquired. The destinations whose transmission date 204 of the mail reply history 301 is “2000/1/3” or later are confirmed. In the mail reply history 301, the corresponding data is one of the mail reply history 304. The destination information history 309 of the data “A3” acquired from the destination ID 205 of the mail reply history 304 is referred to. Since the information of the user ID 209 “U1” cannot be searched, it is determined that the destination is not specified. With reference to the mail history 701, the data 10 of the scoring (every case) 703 of the mail history 705 not specified as the data destination of the destination confirmation 702 of the series of mails after the organization information change date is acquired.

  In step S808, the degree of change of the organization information is determined by adding the scores obtained by scoring 805 and the series of mails by scoring 806 and the opened state by scoring 807. The data “U1” of the user ID 209 in the destination information 213 is confirmed as follows.

  With reference to the organization information determination result 117, “40” is acquired. “10” obtained by scoring the degree of involvement with a series of emails in the process of scoring 806 is acquired. By adding the above, the degree of involvement between the user ID data “U1” and the series of emails is set to “50 points”. The scoring determination 808 is determined to be “50 points” or more.

  In step S809, the user ID “U1” is registered as a user to be deleted from the destination. In step S810, it is determined how to confirm all the users specified as destinations. In the example of the destination information 207, data of “U1”, “U2”, and “U3” is registered in the user ID 209. If all three users have been confirmed, the process is terminated if all users have been confirmed. If there is unconfirmed data, the process returns to step S804.
