Which Internet protocol is used by email clients to retrieve messages from a mail server?

• A. IMAP
• B. POP3
• C. SMTP
• D. FTP

Answer: (A)

Retrieving messages from a mail server is handled by a protocol designed to access and manage those messages stored on the server. IMAP is built for this purpose: it lets you view, organize, and act on emails directly on the server, and keeps the messages there so you can access the same mailbox from multiple devices with full synchronization (folders, read/unread status, flags, searches). POP3, while also a retrieval protocol, typically downloads messages to a single device and may remove them from the server, which makes multi-device access clunkier. SMTP is for sending mail, not retrieving, and FTP is for file transfer unrelated to email. So the protocol used by email clients to retrieve messages from a mail server is IMAP.
