duplicate mails

[Lutz Kittler]

Hi,

I installed cyrus 2.1.15-0woody.1.0 on a debian woody system.
Mail is delivered to cyrus bei postfix  2.0.16-4.woody.1 with lmtp:unix
transport.
In imapd.conf there is by default:
       singleinstancestore: yes
       duplicatesuppression: yes
All mailboxes use the default partition on an ext3-filesystem.

I sent a message to user1 and user2. The messages are identical in
/var/spool/cyrus/mail - directories, but duplicate_check returns 0
and so no hard links are used for the messages.
I also tried it with 
  local_destination_concurrency_limit = 2
in postfix:main.cf, but the same result.

If a user copies a mail to another folder than hardlinks are used.

deliver.db also shows identical Headers :

imap:/var/spool/cyrus/mail# su - cyrus -c "/usr/sbin/ctl_deliver -d"
it is NOW: 1074610001

...
got 13 entries


What can I do ?

 Thanks
