IMAP URL Scheme
Status of This Memo
This document specifies an Internet standards track protocol for the
Internet community, and requests discussion and suggestions for
improvements. Please refer to the current edition of the "Internet
Official Protocol Standards" (STD 1) for the standardization state
and status of this protocol. Distribution of this memo is unlimited.
Abstract
IMAP (RFC 3501) is a rich protocol for accessing remote message
stores. It provides an ideal mechanism for accessing public mailing
list archives as well as private and shared message stores. This
document defines a URL scheme for referencing objects on an IMAP
server.
This document obsoletes RFC 2192. It also updates RFC 4467.

1. Introduction
The IMAP URL scheme is used to designate IMAP servers, mailboxes,
messages, MIME bodies [MIME], and search programs on Internet hosts
accessible using the IMAP protocol over TCP.
The IMAP URL follows the common Internet scheme syntax as defined in
[URI-GEN]. If :<port> is omitted, the port defaults to 143 (as
defined in Section 2.1 of [IMAP4]).

RFC 5092 IMAP URL Scheme November 2007
An absolute IMAP URL takes one of the following forms:
imap://<iserver>[/]
imap://<iserver>/<enc-mailbox>[<uidvalidity>][?<enc-search>]
imap://<iserver>/<enc-mailbox>[<uidvalidity>]<iuid>
[<isection>][<ipartial>][<iurlauth>]
