Speaking as an implementor:

(1) Finish work on existing in-progress Working Group documents:
(a) Body (draft-ietf-sieve-body-07.txt)
Will implement.
(b) Notify mailto (draft-ietf-sieve-notify-mailto.txt)
Undecided, but will consider implementing
(c) Edit header (draft-ietf-sieve-editheader-10.txt)
Will implement
(d) Mime loops (draft-ietf-sieve-mime-loop-04.txt)
Will implement
(e) Refuse/reject (draft-ietf-sieve-refuse-reject-06.txt)
Older version already implemented.
(2) Finalize and publish the following SIEVE extensions as proposed
standards:
(a) Date/Index (draft-freed-sieve-date-index-08.txt)
Will implement
(b) iHave (draft-freed-sieve-ihave-01.txt)
This looks very interesting, but I haven't even started thinking about
how difficult this would be to implement.
(c) Environment (draft-freed-sieve-environment-03.txt)
Will implement
(d) Notary (draft-freed-sieve-notary-01.txt)
Will implement
(e) SIEVE in XML (draft-freed-sieve-in-xml-01.txt)
This looks interesting, even though there is no immediate plan to implement.
(f) Notify-sip (draft-melnikov-sieve-notify-sip-message-01.txt)
I haven't thought about implementing this yet.
(g) ManageSIEVE (draft-martin-managesieve-08.txt)
Implemented.
(h) RegEx (draft-ietf-sieve-regex-00.txt)
I am not sure this will be implemented, no customer requirements so far.
(j) Meta-data (draft-melnikov-sieve-imapext-metadata-03.txt)
Will implement.
(k) Include/multi-script (draft-daboo-sieve-include-05.txt)
I've started implementing something like multiscript and will be looking
at include.
So this looks interesting to me.
(k) Address data (draft-melnikov-sieve-external-lists-01)
Will implement.
(4) Produce one or more informational RFCs containing a set of test
scripts and test email messages that are to be filtered by the
scripts, and the expected results of that filtering. This will serve
as the basis of a interoperability test suite to help determine the
suitability of moving the base specification and selected extensions
to Draft status.
I will definitely participate in this effort, but I can't commit to be
an editor.
