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 field
or other parts of the message.

This document is a product of the Applications Area Working Group Working Group of the IETF.

This is now a Proposed Standard.
