Internet Message Access Protocol definition protocol, messaging
(IMAP) A protocol
allowing a client
to access and manipulate electronic mail
messages on a server
. It permits manipulation of remote message folders (mailboxes
), in a way that is functionally equivalent to local mailboxes.
IMAP includes operations for creating, deleting, and renaming mailboxes; checking for new messages; permanently removing messages; searching; and selective fetching of message attributes, texts, and portions thereof. It does not specify a means of posting mail; this function is handled by a mail transfer protocol such as SMTP
