The user table 151a is a table that stores user information indicating a correspondence relationship between each user belonging to the organization 30 and a mail address of an e-mail used by each user.

  In the user table 151a, "ID" which is an item indicating an ID (Identification) set for a user in the organization 30, "User name" which is an item indicating the user's name, and an item which indicates the user's organization mail address "Organization mail address" and "Safety mail address" which is an item indicating the safety mail address of the user are provided. Information arranged in the horizontal direction of each item is associated with each other to constitute user information. This user information functions as transfer destination address information. Although omitted here, the user information includes a password for authenticating the user in combination with the ID.

  The ID is a code set for each user in order to identify each user on a mail system such as the mail server 100. For this reason, although an arbitrary character string can be used for ID, it is determined so that the user can be uniquely specified for each user. The user name is the name of each user who belongs to the organization 30 and uses the mail system. The organization email address is the email address of the email that the user normally uses in the organization 30. The safety e-mail address is an e-mail address used by the user personally and used as a forwarding destination of the safety request e-mail in the organization 30 in an emergency.

  Here, in the mail server 100 of the present embodiment, the safety mail address of each user is registered in the mail server 100 by the user himself / herself at the safety mail address. Further, the safety mail address registered in the mail server 100 is restricted in access by the mail server 100 and protected by personal authentication such as an ID and a password. Thereby, the safety mail address can be viewed only from the user account of the safety mail address. Thereby, the safety mail address which is personal information is protected.

Next, an organization table used in the mail server 100 of this embodiment will be described.
FIG. 6 is a diagram illustrating a data structure of the organization table. The organization table 152a illustrated in FIG. 6 is created and managed by the mail server 100.

  The organization table 152a is provided with “boss ID” which is an item indicating the ID of the boss and “user ID” which is an item indicating the ID of a user who is a subordinate of the boss. Information arranged in the horizontal direction of each item is associated with each other to form organization information.

  Here, in the present embodiment, when a plurality of subordinates (for example, ichirou, jirou, saburou) exist for one boss (for example, hanako), for example, the organization table 152a shown in FIG. As shown in the first to third lines from above, a plurality of organization information is created for the same boss, and different subordinate user IDs are associated with the same boss boss ID in each organization information. .

Next, the safety table used in the mail server 100 of this embodiment will be described.
FIG. 7 is a diagram illustrating a data structure of the safety table. A safety table 153 a shown in FIG. 7 is created and managed by the mail server 100. The safety table 153a is a table that stores safety information indicating a connection destination in each communication carrier.

  The safety table 153a is provided with “ID”, “user name”, “status” which is an item indicating the safety status of the user, and “update time” which is an item indicating the update time of the safety information. Information arranged in the horizontal direction of each item is associated with each other to constitute safety information.

  The status indicates whether or not safety is collected and the collected user's safety status. Status includes, for example, “No reply” for which safety has not been confirmed, “Safe” for confirmed safety, “Injury” for confirmed injuries, “Other” for confirmed others, etc. Can be set. Other statuses can be set as necessary. The update time is the time when the user's safety information was last updated. As a result, it is possible to indicate when the safety information of the user is the one at the time. For example, for the user whose safety is not confirmed, some action is taken to confirm the safety or the state is observed for a while. It can be used as a reference when making decisions.

With this safety information, the mail server 100 can store the result of the user's safety confirmation at that time, and can provide it as necessary.
Next, a processing procedure in the present embodiment will be described. First, the safety request process executed when transmitting the safety request mail (see FIG. 11) for requesting the safety notification to the user's safety mail address in the mail server 100 of the present embodiment will be described.

FIG. 8 is a flowchart showing the procedure of the safety request process.
When the mail server 100 according to the present embodiment receives a safety request instruction from an administrator of the mail server 100 or the like, the mail server 100 starts execution of the safety request process accordingly. Here, the safety request instruction is an instruction that the administrator of the mail server 100 requests the mail server 100 to notify the user belonging to the organization 30 of safety. The administrator of the mail server 100 issues a safety request instruction from the terminal device 31 or the like. This safety request instruction may be performed by transmitting a predetermined mail to the mail server 100 or may be performed by operating the mail server 100 directly.

  [Step S11] Upon receiving the safety request instruction, the CPU 101 of the mail server 100, from the user information (see FIG. 5), among the users belonging to the organization 30, a transmission destination that transmits a safety request mail requesting safety notification. The organization mail address and safety mail address of the request-destination user who is the current user are acquired. This request destination is normally set so as to target all users, but users who do not need to confirm safety as necessary may be excluded.

  [Step S12] The CPU 101 transmits a safety request mail to the organization mail address and safety mail address of the request destination user acquired in step S11. Thereafter, the process ends.

  Here, the user who has received the safety request mail transmitted from the mail server 100 by the safety request process logs in to the mail system provided by the mail server 100. Next, the logged-in user creates a safety notification mail for notifying safety about the safety request mail to the mail server 100 in the web mail provided by the mail system, and transmits it to the mail server 100. As a result, the user whose safety request is requested by the safety request mail logs in to the mail system provided by the mail server 100 and communicates the safety by sending the safety contact mail created using the web mail. be able to.

  This safety notification mail is associated with the status of the safety table 153a (see FIG. 7). For example, if the user reports “safe”, enter “a” in the body text in the safety notification email and send it, and if “injury” is communicated, enter “ka” in the text body. If it is “Other”, enter “T” into the text and send it. Next, based on these, the mail server 100 automatically acquires the safety of each user from the safety notification mail.

  Next, in the mail server 100 of the present embodiment, a safety information update process for collecting and updating safety communications by the user and reporting the collected safety to a safety manager such as a boss will be described. 9 and 10 are flowcharts showing the procedure of the safety information update process.

  When the mail server 100 according to the present embodiment receives the safety contact mail transmitted by the user based on the safety request mail transmitted by the safety request process of FIG. 8, the safety server (see FIG. 7) updates the safety information (see FIG. 7). In addition to reporting, the safety information collected every predetermined period is reported to the supervisor. This safety request process is started by the mail server 100 when a safety request instruction is issued by the administrator of the mail server 100.

  [Step S <b> 21] The CPU 101 determines whether or not a safety contact mail or a proxy contact mail by the user's supervisor is newly received from the user. If it is newly received, the process proceeds to step S22. On the other hand, if not newly received, the process proceeds to step S31 (see FIG. 9).

  Here, for example, when the user's boss cannot send the safety notification mail and confirms the safety by a different means such as a telephone, the proxy contact mail is safe for the mail server 100. Is an email for contacting the user on behalf of the user.

  The proxy contact mail is, for example, a log-in to the web mail by the boss, and the mail server 100 addressed to the user ID of safety (see FIG. 5) and the character indicating the above status ("A" if safe) If you are injured, enter "ka", otherwise enter "ta") in the body and send.

  [Step S22] Based on the received safety contact mail or proxy contact mail, the CPU 101 updates the status and update time of the safety information of the user newly notified of safety by the safety contact mail or proxy contact mail.

  [Step S23] The CPU 101 acquires the supervisor of the user who is newly notified of safety from the organization information (see FIG. 7). Next, the CPU 101 acquires the acquired organization email address and safety email address of the supervisor from the user information (see FIG. 5).

  [Step S24] The CPU 101 transmits an email including the safety information of the user who is newly notified of safety to the organization email address and safety email address acquired in step S23. Thereafter, the process proceeds to step S21.

  [Step S31] The CPU 101 determines whether or not a predetermined time has elapsed since the safety request instruction was issued (if the safety information collected has been transmitted to the boss once or more, since the previous transmission). If the predetermined time has elapsed, the process proceeds to step S32. On the other hand, if the predetermined time has not elapsed, the process proceeds to step S21 (see FIG. 9).

  [Step S32] If there is a user whose safety is not yet communicated by either the safety notification mail or the proxy contact mail, the CPU 101 extracts the user and updates the status and update time of the collected safety information.

  [Step S33] The CPU 101 obtains the superior of the user whose safety is not yet communicated from the organization information (see FIG. 7). Next, the CPU 101 acquires the acquired organization email address and safety email address of the supervisor from the user information (see FIG. 5).

  [Step S34] The CPU 101 transmits a mail including the safety information of the user extracted in step S32 to the safety mail address acquired in step S33. Thereafter, the process proceeds to step S21 (see FIG. 9).

Next, a safety request mail transmitted from the mail server 100 according to the present embodiment to a safety mail address to a user who requests safety notification will be described.
