I have reviewed this document as part of the Operational directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written with the intent of improving the operational aspects of the IETF drafts. Comments that are not addressed in last call may be included in AD reviews during the IESG review. Document editors and WG chairs should treat these comments just like any other last call comments. Summary: This document draft-ietf-extra-imap-savedate adds a new capability to the Internet Message Access Protocol (IMAP). The new capability adds IMAP attribute 'save date' that indicates the moment at which the message was saved in the mailbox. The new capability extends FETCH and SEARCH commands for the 'save date' attribute. The discovery of support for the new capability and response to commands when it is not supported is documented. It appears to be ready from the operational perspective.
