Retrieved from ” https: It is also possible to attach annotations to specific parts of a message, so that, for example, they could be marked as seen, or important, or a comment added. Not using sequence numbers would render many of these moot. These problems need to be solved somehow – maybe inherently in a different protocol, maybe explicitly.
The Conditional Store facility also allows a client to quickly resynchronize mailbox flag changes. Ideally not too different – reuse as much as possible. Retrieved 26 November The IMAP4 protocol supports both predefined system flags and client-defined keywords. Massive deadwood cleaning required here. Expand scope considerably – IDLE is insufficient for many users, because it only monitors one mailbox.
Ideally composible actions – first characters of decoded value of part “1.
Internet Message Access Protocol
E-mail clients using IMAP generally leave messages on the server until the user explicitly deletes them. For instance, the specification states that each message stored on the server has a “unique id” to allow the clients to identify messages they have already seen between sessions. The hard bit will be extra things like metadata, condstore, which it doesn’t seem to consider – so it’s incomplete. Will need an Access Control mechanism.
Notification of mail arrival is done through in-band signalingwhich contributes to the complexity of client-side IMAP protocol handling somewhat. Incoming e-mail messages are sent to an e-mail server that stores messages in the recipient’s e-mail box. This specification defines the generic URI syntax and a process for resolving URI references that might be in relative form, along with guidelines and security considerations for the use of URIs on the Internet.
RFC – INTERNET MESSAGE ACCESS PROTOCOL – VERSION 4rev1
Access to remote mailboxes not fundamentally different from local access. Common use case is “add a rule to filter messages matching X into a folder, and also apply that to the messages in INBOX now so existing ones get copied”. Has some best-practices how well-behaving IMAP servers should behave. With the IDLE command, the server can tell the client that a mailbox status has changed.
IBM ‘s Notes client works in a similar fashion when communicating with a Domino server. Need to rrfc the sort as well [ http: May need to consider individual folders vs “entire user” in the context of folder-level ACLs. 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.
There’s not even an attempt to include address book, calendaring, etc in this list yet! Hosted by Red Hat.
In doubt, RFC is authorative. Exactly what we’re planning here – everything you can do with Lemonade should be supported – not necessarily in the same way. In particular, omap pairs of mutually exclusive options with a “tristate” makes sense.
Non-authorative addendum to RFC Was there 5301 a point? This page was last edited on 27 Decemberat Clients may store local copies of the messages, but these are considered to be a temporary cache.
It defines several new access control rights and clarifies iimap rights are required for different IMAP commands.
This document is a revision of RFC Set a baseline of “required supported features” to get a better experience. Much of this complexity e. Many IMAP4 extensions to the base protocol have been proposed and are in common use.
While some clients and servers preferentially use vendor-specific, proprietary protocols almost all support POP and IMAP for retrieving e-mail – allowing many free choice between many e-mail clients such as Pegasus Mail or Mozilla Thunderbird to access these servers, and allows the clients to be used with 35501 servers. Unlike some proprietary protocols which combine sending and retrieval operations, sending a message and saving a copy in a server-side folder with a base-level IMAP client requires transmitting the message content twice, once to SMTP for delivery and a second time to IMAP to store in a sent mail folder.
However, the specification also allows these UIDs to be invalidated with no restrictions, practically defeating their purpose. This mechanism avoids requiring clients to download every message in the mailbox in order to perform these searches. Views Read Edit View history.
