I suspect that your cyrus is configured to use the . as hierarchy seperator.
see "unixhierarchysep:" in imapd.conf manpage for details.

Master is the name of the main development branch in git. A new branch for
cyrus imapd 3.0 will be forked from the master branch with the release of
the new version.
