解説

問 92

Incorrectア
The protocols for sending and receiving are reversed. In email, SMTP is used for sending and POP3 (or IMAP) for receiving. The statement that uses SMTP for receiving and POP3 for sending swaps their roles, so it is wrong.
Incorrectイ
A mailing list is a mechanism whereby simply sending to a single representative list address delivers the message to all registered members. The recipient field of a received email does not list the addresses of all registered members, so it is wrong.
Incorrectウ
The domain name is the part to the right of the “@” in an email address, while the left side is the user name (local part). The delivery destination is determined based on the domain name on the right, so the statement that forwarding is based on the domain name in the left part mixes up left and right and is wrong.
エ
正解 The correct answer is エ. An email forwarding service (mail forwarding) is a mechanism that automatically forwards email arriving at one address to another address specified in advance. Using it, you can gather all the email sent to the multiple email addresses you hold under your own name into a single mailbox to receive, store, and manage them. The statement describes this behavior correctly, so it is appropriate.

ここがポイント

Roles of the main email protocols: SMTP for sending, POP3／IMAP for receiving. Do not confuse sending with receiving.
An email address is structured as “local part (user name)@domain name”, and delivery is performed based on the domain name to the right of the “@”.
