IMAP (Internet Mail Access Protocol) is a protocol that is used to access email messages that are stored on a mail server. IMAP allows users to retrieve, delete, and manage email messages without having to download them to their local device.

SMTP (Simple Mail Transfer Protocol) is a protocol that is used to send email messages between servers. When an email is sent, it is delivered to the recipient’s mail server using SMTP.

POP3 (Post Office Protocol version 3) is a protocol that is used to retrieve email messages from a mail server. When a user connects to their mail server using POP3, they can download the messages to their local device and delete them from the server.

IMAP, SMTP, and POP3 have commonly used protocols in the Internet email system. They are used by email clients, such as Microsoft Outlook and Apple Mail, to communicate with email servers and manage email messages.
