The IESG has received a request from the Email mailstore and eXtensions To Revise or Amend WG (extra) to consider the following document: - 'Internet Message Access Protocol (IMAP) - STATUS=SIZE Extension' <draft-ietf-extra-imap-status-size-01.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2018-05-10. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract This document adds a new capability called "STATUS=SIZE" to the Internet Message Access Protocol (IMAP). It allows retrieving the total storage size of a mailbox with a single STATUS command rather than retrieving and summing the sizes of all individual messages in that mailbox. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-extra-imap-status-size/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-extra-imap-status-size/ballot/ No IPR declarations have been submitted directly on this I-D.
