Except making LIST extensible and giving tiny bandwidth improvements and tiny server performance improvements There are a few cases covering list andling – it’s a lot more complex than the small amount of actual data involved justifies. Expand scope to include other objects annotations, keywords, num-folders, etc consistently.

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. 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 5301.

IMAP was designed umap Mark Crispin in as a remote access mailbox protocol, rrc contrast to the widely used POP, a protocol for simply retrieving the contents of a mailbox. Current group scheduling and Personal Information Management PIM products are being extended for use across the Internet, today, in proprietary ways. Exactly what we’re planning here – everything you can do with Lemonade should be supported – not necessarily in the rf way.

Views Read Edit View history. In addition to this, Courier Mail Server offers a non-standard method of sending using IMAP by copying an outgoing message to a dedicated outbox folder. From Wikipedia, the free encyclopedia. These mechanisms allow clients to retrieve the text portion of a message without retrieving attached files or to stream content as it is being fetched.


IMAP keywords should not be confused with proprietary labels of web-based e-mail services which are sometimes translated into IMAP folders by the corresponding proprietary servers. In particular, replacing pairs of mutually exclusive options with a “tristate” makes sense. Access to remote mailboxes not fundamentally different from local access.

Ideally composible actions – first characters of decoded value of part “1. Specifies a method to synchronise a client with a server after some time for the client being offline. See comment – will be mooted.

RFC List Every RFC is the work of someone who felt enough pain from the lack of something that they would make the effort to write the document. An Email Filtering Language and all the extentions Support Sieve – possibly even sieve fragments as “run this filter on this mailbox”.

The current version is defined by RFC Heirarchy separator will either be forced or not exist tree data structure on the wire. It will be imao human-typing-friendly, but more machine friendly.

Has some best-practices how well-behaving IMAP servers should behave. Many IMAP4 extensions iap the base protocol have been proposed and are in common use.

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. Will need an Access Control mechanism.

Internet Message Access Protocol

This experimental revision was called IMAP2bis; its specification was never published in non-draft form.

Usually all Internet e-mail is transmitted in MIME format, allowing messages to have a tree structure where the leaf nodes are imwp of a variety of single part content types and the non-leaf nodes are any of a variety of multipart types. The IMAP specification has been criticised for being insufficiently strict and allowing behaviours that effectively negate its usefulness.

Ideally, part of a more general “compose commands” – but the ability to store a search result for later manipulation will be needed.


IMAP, Internet Message Access Protocol

Will need some form of Quota. 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”. It defines several new access control 350 and clarifies which rights are required for different IMAP commands. Fix insufficient information being returned from commands to synchronise state. This will need to be addressed in individual sections.

With the IDLE command, the server can tell the client that a mailbox status has changed. This memo has been defined to provide the definition of a common format for openly exchanging calendaring and scheduling information across the Internet.

Clients may store local copies of the messages, but these are considered to be a temporary cache. This page was last edited on 27 Decemberat Make sure protocol supports simple access to emails. The IMAP4 protocol supports both predefined system flags and client-defined keywords. Also need to handle the case of “partial IO error” – where data exists but can not be returned immediately for some reason.

The Conditional Store facility also 35001 a client to quickly resynchronize mailbox flag changes.

evolution-kolab – RFC Reference

An IMAP server typically listens on port number This mechanism avoids requiring clients to download every message in the mailbox in order to perform these searches. Ideally part of a more generic “batch operations” – more discussion required. Keywords, which are not supported by all IMAP servers, 3510 messages to be given one or more tags whose meaning is up to the client.

IMAP4 provides a mechanism for a client to ask the server to search for messages meeting a inap of criteria.
