Hi,

I'm trying to get the so-called "single instance store" (I think cyrus has got the name for the first time) with dovecot --version = 2.0.19 binary package installed from ubuntu 12.04 lts official repo.

As requested, here is my update. As you can see I am running now the latest release however emails delivered through lmtp gets split into different files instead of expected hardlinked files.

Please pay attention as I'm commenting in-between different pasted outputs:

for your pleasure, here is the transaction (note the same queue id and a single lmtp session for all three recipients)
