The IESG has received a request from the Email mailstore and eXtensions To Revise or Amend WG (extra) to consider the following document: - 'Sieve Email Filtering: Delivering to Special-Use Mailboxes' <draft-ietf-extra-sieve-special-use-04.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 2018-12-20. 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 The SPECIAL-USE capability of the IMAP protocol (RFC 6154) allows clients to identify special-use mailboxes; e.g., where draft or sent messages should be put. This simplifies client configuration. In contrast, the Sieve mail filtering language (RFC 5228) currently has no such capability. This memo defines a Sieve extension that fills this gap: it adds a test for checking whether a special-use attribute is assigned for a particular mailbox or any mailbox, and it adds the ability to file messages into an anonymous mailbox that has a particular special-use attribute assigned. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-extra-sieve-special-use/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-extra-sieve-special-use/ballot/ No IPR declarations have been submitted directly on this I-D.
