Which protocol is used to retrieve emails from a mail server?

• A. Post Office Protocol / Internet Message Access Protocol
• B. Simple Mail Transfer Protocol
• C. Hypertext Transfer Protocol
• D. File Transfer Protocol

Answer: (A)

Retrieving emails from a mail server uses specific retrieval protocols, namely POP3 (Post Office Protocol) and IMAP (Internet Message Access Protocol). The option that lists both of these is correct because it directly references the protocols designed for fetching messages from a server. SMTP, on the other hand, is used for sending mail from a client to a server or between servers. HTTP is for accessing web resources, and FTP is for transferring files. So they aren’t used to retrieve emails. In practice, POP3 downloads messages to a device (often removing them from the server, if configured that way), while IMAP interacts with messages on the server to keep them synchronized across devices.
