IMAP IDLE

Last updated

In email technology, IDLE is an IMAP feature described in RFC 2177 that allows a client to indicate to the server that it is ready to accept notifications in real time. [1]

Contents

Significance

The IDLE feature allows IMAP email users to immediately receive any mailbox changes without having to undertake any action such as clicking on a refresh button, or having the email client automatically and repeatedly ask the server for new messages. [2]

Usage

IMAP4 servers that support IDLE will include the string "IDLE" in the result of their CAPABILITY command. This allows email users to receive near instant notification of a new email. [3]
