The IESG has received a request from the Applications Area Working Group WG (appsawg) to consider the following document: - 'Sieve Email Filtering: Detecting Duplicate Deliveries' <draft-ietf-appsawg-sieve-duplicate-06.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 2014-06-12. 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 defines a new test command "duplicate" for the "Sieve" email filtering language. This test adds the ability to detect duplications. The main application for this new test is handling duplicate deliveries commonly caused by mailing list subscriptions or redirected mail addresses. The detection is normally performed by matching the message ID to an internal list of message IDs from previously delivered messages. For more complex applications, the "duplicate" test can also use the content of a specific header or other parts of the message. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-appsawg-sieve-duplicate/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-appsawg-sieve-duplicate/ballot/ No IPR declarations have been submitted directly on this I-D.
