Archived from the original on Multiple mailbox support also allows servers to provide imxp to shared and public folders.

Was there really a point? Need rrfc fix the sort as well. But this one has a problem, it doesn’t let you sort across folders, which makes it only half the solution. See comment – will be mooted. Specifies a method to synchronise a client with a server after some time for the client being offline.

It will be less human-typing-friendly, but more machine friendly.

Extend more – allow both private and shared “special uses”, because there are contexts where both make sense. Retrieved 26 November The best approach for ‘push’ inap.

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. Folder listing is one of the major pain points for client authors.

Internet Message Access Protocol

Specify quota and ACL handling currently different for keywords and annotations. These clients need a mechanism to synchronize state changes for messages within the mailbox. Massive deadwood cleaning required here. Many IMAP4 extensions to the base ffc have been proposed and are in common use. See for example RFC section 5.

However, the specification also allows these UIDs to be invalidated with no restrictions, practically defeating their purpose. The IMAP4 protocol allows clients to retrieve any of the individual MIME parts separately and also to retrieve portions of either individual parts or the entire message.

BURL is too complex from a “interacting systems, firewalls and authentication methods” perspective. 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.

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.

Unless the mail storage and searching algorithms on the server are carefully implemented, a client can potentially consume large amounts of server resources when searching massive mailboxes. This specification does not define a generative grammar for URIs; that task is performed by the individual specifications of each URI scheme.

Through the use of flags defined in the IMAP4 protocol, clients can keep track of message state: Sending mail via an IMAP connection”. It is possible to store data on a per-mailbox basis or on the server as a whole.

Make it easy to not only get status data, but to get a list of which folders have changed since last request. Access to remote mailboxes not fundamentally different from local access.

System flags indicate state information such as whether a message has been read. There are a few cases covering list andling – it’s a lot more complex than the small amount of actual data involved justifies. Set a baseline of “required supported features” to get a better experience.

Hosted by Red Hat. An example of such an application is use of an IMAP mailbox as a message queue with multiple dequeueing clients. The user ima the messages with an e-mail client that uses one of a number of e-mail retrieval protocols.

Views Read Edit View history. Usually all Internet e-mail is transmitted in MIME format, allowing messages to have a tree structure where the leaf nodes are any of a variety of single part content types and the 35011 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.

The Internet Message Access Protocol is an Application Layer Internet protocol that allows an e-mail client to access e-mail on a remote mail server. It defines several new access control rights and clarifies which rights are required for different IMAP commands. Examples include different clients working on behalf of the same user, and multiple users accessing shared mailboxes.

The hard bit will be extra things like metadata, condstore, which it doesn’t seem to consider – so it’s incomplete. Unlike some proprietary protocols which combine 33501 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.

Reflecting the experience of earlier Internet protocols, IMAP4 defines an explicit mechanism by which it may be extended.
