Internet Message Access Protocol

Application layer protocol for e-mail retrieval and storage

In computing, the Internet Message Access Protocol (IMAP) is an Internet standard protocol used by email clients to retrieve email messages from a mail server over a TCP/IP connection. IMAP is defined by RFC 9051. IMAP was designed with the goal of permitting complete management of an email box by multiple email clients; therefore, clients generally leave messages on the server until the user explicitly deletes them.
