What is IMAP and How does it work?

Answer 1

IMAP, or internet Message Access Protocol, is a protocol used by email clients to retrieve and manage messages from a mail server. Unlike POP3, which downloads emails to a local device and typically removes them from the server, IMAP allows users to view and organize their emails while keeping them stored on the server. This enables seamless access to emails across multiple devices, as changes made in one location (such as reading or deleting messages) are reflected everywhere. IMAP operates over TCP/IP and typically uses port 143 for unencrypted connections and port 993 for secure connections.
