[ingo] Sieve filter for duplicate emails from mailing lists?

[Brett Charbeneau]

       Seeing as Ingo is a front end for more than one filtering  
languages it can't be all things to all people. That being said, has  
anyone figured out how to make Ingo using Sieve delete/move the double  
copies of identical messages users posting to mailing lists frequently  
get?
       I see some possibly useful examples at

http://hg.rename-it.nl/dovecot-2.1-pigeonhole/raw-file/tip/doc/rfc/spec-bosch-sieve-duplicate.txt

       but I can't figure out how I could possibly use these scripts  
even with command line access to the server.
       I'm presently using Ingo 3.1.3 with the prefs backend.
