Ideally rffc of a more generic “batch operations” – more discussion required. IMAP was designed by Mark Crispin in as a remote access mailbox protocol, in contrast to the widely used POP, a protocol for simply retrieving the contents of a mailbox. This will need to be addressed in individual sections. This specification does not define a generative grammar for URIs; that task is performed by the individual specifications of each URI scheme.

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


This is almost a replacement protocol in itself – hopefully it will map almost untouched. 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.

Moreover, single parts of emails may be annotated, e. Fix insufficient information being returned from commands to synchronise state. 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.


This specification defines the generic Imapp 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.

The Conditional Store facility also allows a client to quickly resynchronize mailbox flag changes. Would love to make this more general – sort by a somewhat arbitrary function on the message.

Expand scope to include other objects annotations, keywords, num-folders, etc consistently. Incoming e-mail messages are sent to an e-mail server that stores messages in the recipient’s e-mail box.

The best approach for ‘push’ e-mail”. Need to fix the sort as well [ http: Not using sequence numbers would render many of these moot. 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 which rights are required for different IMAP commands. Heirarchy separator will either be forced or not exist tree data structure on the wire.

These problems need to be solved somehow imqp maybe inherently in a different protocol, maybe explicitly. 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.

An Email Filtering Language. Explicity allow space for extention. Folder listing is one of the major pain points for client authors.

Internet Message Access Protocol

Make sure protocol supports simple access to emails. 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. 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”. IMAP4 provides a mechanism for a client to ask the server to search for messages meeting a variety of criteria.


Less necessary with higher resources available today. System flags indicate state information such as whether a message has been read. The specification has an example: This experimental revision was called IMAP2bis; its specification was never published in non-draft form. Either use them as-is, or map into annotation-space.

Archived from the original on Retrieved from ” https: The POP protocol requires the currently connected client to be the only client connected to the mailbox. Much of this complexity e.

No copies of the original interim protocol specification or its software exist. This page was last edited on 27 Decemberat Multiple mailbox support also allows servers to provide access to shared and public imao. Hosted by Red Hat. See comment – will be mooted.

Massive deadwood cleaning required here. Email Unicode and email.
