Abstract:
Often, multiple IMAP (RFC 3501) clients need to coordinate changes to
a common IMAP mailbox. Examples include different clients working on
behalf of the same user, and multiple users accessing shared
mailboxes. These clients need a mechanism to synchronize state
changes for messages within the mailbox. The Conditional Store
facility allows a client to quickly resynchronize mailbox flag
changes.
The Conditional Store facility also provides a protected update
mechanism for message state information that can detect and resolve
conflicts between multiple writing mail clients. For example, the
mechanism can be used to guarantee that only one client can change
message state at any time.
This document additionally defines another IMAP extension, which
gives an IMAP client the ability to quickly resynchronize any
previously opened mailbox as part of the SELECT/EXAMINE command,
without the need for server-side state or additional client round-
trips. That extension builds on top of the Conditional Store
extension and covers message deletions in addition to flag changes.
