解説
問 77
Incorrectア
Email sent indiscriminately and in large volumes for commercial purposes such as advertising or solicitation, without the recipient's consent, is the description of spam. A mailing list is decisively different in that the receiving side has registered as a member by their own choice; it is not indiscriminate sending.
Incorrectイ
The function of sorting received email into individual folders for management describes the sorting (filtering) feature of a mail client, which is about organizing on the receiving side. A mailing list is a mechanism that delivers to all registered members at the time of sending, so both its purpose and its behavior are different.
Incorrectウ
What describes the correspondence between server names (domain names) and IP addresses is name-resolution data such as DNS information or a hosts file, which serves to identify the destination server. Although it forms the basis for determining a mail delivery route, it has nothing to do with broadcasting to all members.
- エ
正解 The correct answer is エ. A mailing list is a mechanism in which the email addresses of members are registered in advance, and simply sending a single email to the representative address prepared for that group causes the message to be automatically forwarded (broadcast) to the addresses of all registered members. The sender does not need to know the individual recipients; writing just the one representative address in the To field is enough, so mailing lists are used for contacting fixed groups such as departments, projects, or clubs, and for discussion among members. Adding and removing members is managed centrally on the list side, so even when the participants change, the sender can keep using the same representative address. The wording of エ states exactly this behavior of sending to a specific address and having the message forwarded to all registered members, so it is an appropriate description of a mailing list.
ここがポイント
- A mailing list is a mechanism for broadcasting to all registered members with a single send. Sending to one representative address forwards the message to everyone, and member management can be handled centrally on the list side.
- Learn to distinguish email-related terms: spam is indiscriminate mass sending without consent, sorting (filtering) is the automatic organizing of received mail, and DNS is the mapping between names and IP addresses; none of these is a mailing list.
