Hi,
A while back I built a non-standard Sieve extension for detecting
duplicate message deliveries, e.g. as seen when people cross-post over
multiple mailing lists. This functionality is very similar to what could
be achieved with Procmail using formail -D. Someone requested this at
some point and in a moment of boredom I built the initial
implementation. Last year I extended it a bit and I made it more
generic. I never intended for this to be standardized, but - now that I
look at it again - I think this may yet be of some interest to other
Sieve implementers as well.
I make a habit of documenting my custom Sieve extensions in a familiar
RFC-like manner:
http://hg.rename-it.nl/dovecot-2.1-pigeonhole/raw-file/tip/doc/rfc/spec-bosch-sieve-duplicate.txt
What do you think? Would you be interested in having functionality like
this standardized? Should I submit this as a draft?
Regards,
Stephan.
