Which protocol allows a client to access and manipulate mail messages on a server?

• A. POP
• B. SMTP
• C. FTP
• D. IMAP

Answer: (D)

IMAP is designed to access and manage mail messages that stay on the mail server, allowing you to read, delete, move between folders, and flag messages while keeping the mailbox synchronized across devices. This server-side presence means you can manipulate messages from multiple clients without downloading everything locally. POP, by contrast, typically downloads messages to the client and may remove them from the server, which makes server-side manipulation across devices less reliable. SMTP is for sending messages, not retrieving or managing existing ones, and FTP is a general file-transfer protocol with no built-in mailbox semantics.
