I've done this 36h ago and since that moment no mailbox got broken again. If someone else is having the same problem - this are the steps I have done: - Create a new volume with Ext4 and mount it - Shutdown Cyrus - Run "reconstruct -O -r user.*" as user cyrus to repair all broken mailboxes. (I run it twice, just to be sure, that everything is fine. :-)) - Copy the content from /var/spool/imap to the new Ext4 volume. - Mount the Ext4 volume to /var/spool/imap (don't forget to change your /etc/fstab entry!) - Because I'm paranoid, I run the above reconstruct again - now on the Ext4 volume. - Started Cyrus. My server is running Scientific Linux 6.1 (x86_64). All software was installed from the repository (just cyrus is selfcompiled). All kernel settings are also left on their default.
