"IMAP4 Multimailbox SEARCH Extension", Barry Leiba, Alexey Melnikov, 7-Jul-09. ( bytes)

The IMAP4 specification allows the searching only of the selected mailbox. A user often wants to search multiple mailboxes, and a client that wishes to support this must issue a series of SELECT and SEARCH commands, waiting for each to complete before moving on to the next. This extension allows a client to search multiple mailboxes with one command, limiting the round-trips and waiting for various searches to complete, and not requiring disruption of the currently selected mailbox. This also uses MAILBOX and TAG fields in ESEARCH responses, allowing a client to pipeline the searches if it chooses. Note A revised version of this draft document will be submitted to the RFC editor as a Proposed Standard for the Internet Community. Discussion and suggestions for improvement are requested, and should be sent to morg@ietf.org.

"IMAP4 Extension for returning STATUS information in extended LIST", Alexey Melnikov, Timo Sirainen, 13-May-09. ( bytes)

Many IMAP clients display information about total number of messages/ total number of unseen messages in IMAP mailboxes. In order to do that they are forced to issue a LIST or LSUB command, to list all available mailboxes, followed by a STATUS command for each mailbox found. This document provides an extension to LIST command that allows the client to request STATUS information for mailboxes together with other information typically returned by the LIST command. Note A revised version of this draft document will be submitted to the RFC editor as a Proposed Standard for the Internet Community. Discussion and suggestions for improvement are requested, and should be sent to morg@ietf.org.
