An IT administrator is configuring a mail client for a user who needs to manage their inbox across multiple devices, including a laptop, a tablet, and a smartphone. The user requires that actions such as marking an email as read, flagging messages, or organizing them into folders are instantly synchronized across all of these devices, with the messages remaining stored on the central mail server.
Which protocol must the administrator configure for incoming mail retrieval to satisfy these requirements?
POP3
SMTP
IMAP
HTTPS
