    Friends,<br>
    The man page for imapd.conf contains this note (emphasis added):<br>
    <blockquote>defaultpartition: &lt;none&gt;<br>
      The partition name used by default for new mailboxes. <b>If not
        specified, the partition with the most free space will be used
        for new mailboxes.</b><br>
    </blockquote>
    However, with the advent of ZFS and other filesystems with Thin
    Provisioning, it is common for all partitions to have the same
    amount of free space reported by the filesystem.  For example, this
    from a client's system with 30 data partitions and 30 meta-data
    partitions:<br>

    In light of this, we intend to have our account creation scheme base
    its choice on space used, rather than free space.  But, would it be
    possible, in light of the wide spread adoption of thin provisioned
    filesystems, to have the default behavior changed in 2.5 or some
    future version of Cyrus imapd?<br>

    Thanks in advance,<br>
