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.
