single message store

[Chris Picton]

Hi I am running postfix with cyrus and trying to enable single message
store.  It isnt working, though.

In postfix main.cf, I have:
local_destination_concurrency_limit = 20
default_destination_concurrency_limit = 10

In imapd.conf, I have:
singleinstancestore: yes

However, I don't get messages hard linked to each other in
/var/spool/imap.

Where could I be going wrong?

My postfix log for a sample mail says (note that the queue ID is the
same for all, so I am assuming that postfix is sending the same message
to multiple recipients via LMTP):
