[Dovecot] sieve copy extension

[Scott Murman]

I want (need) to get the sieve copy extension working for the deliver
LDA.  the latest cyrus imap distro (v2.3 or greater) contains a libsieve
which supports it.  the dovecot-LDA cvs branch uses an older cyrus
distro (looks like v2.1).  has anyone meshed deliver with the new
libsieve?  if not, any estimates of how much of my time it would chew
up?  thanks.
