I'm not aware of a patch against cyrus-imapd from within the Kolab universe,
that is related to RFC 5464.
The only patch I can think of, that relates to this message is the ability to
set arbitrary annotations through Cyrus[1,2].
Both (remotely) annotation-related patches have been applied in Cyrus IMAP
That said, I have to warn you that the other patches listed on the page
referred to are not necessarily feasible technical implementations of the

I suppose what we need to have is a master RFC-5464 bugzilla ticket, possibly
split out over the several tasks completing the full implementation -Bron can
best be the judge on which RFC 5464 components to implement at the same time
while touching the code, as well as determine what is feasible to implement
*now* vs. what is feasible to target for a future release -in the 2.5 series?
