Hi, there!
I'm Running Zimbra 7.0 in CentOS 5.5. Following the tip in this thread


I enabled cbpolicyd in my zimbra running
zmprov ms correio.mydomain.com zimbraServiceEnabled cbpolicyd
and now when I try to start zimbra I get the following thing

[zimbra@correio ~]$ zmcontrol start
Host correio.mydomain.com
Starting ldap...Done.
Starting zmconfigd...Done.
Starting cbpolicyd...Done.
[zimbra@correio ~]$

If I try to disable running
zmprov ms correio.mydomain.com zimbraServiceDisabled cbpolicyd
I get the message (once zimbra is stopped)

cbpolicyd[] INFO: I/O exception (java.net.ConnectException) caught when processing request: Connection refused
[] INFO: Retrying request
ERROR: zclient.IO_ERROR (invoke Connection refused, server: localhost) (cause: java.net.ConnectException Connection refused)

the last line in cbpolicyd.log is
[2011/04/30-08:52:26 - 4082] [CORE] NOTICE: Setting gid to "500 500"

And all I have in zimbra.log is
