IMAP (Internet Message Access Protocol)
IMAP (Internet Message Access Protocol) is a standard email protocol that allows users to access and manage their emails on a remote mail server, ensuring messages are synchronized across multiple devices.
Unlike POP3, which downloads emails to a local device, IMAP keeps emails on the server and allows users to organize, delete, or flag messages from any device. This is particularly useful for managing email across multiple devices, as changes made on one device are reflected on all others.
