 Solution Found!
I found the solution.
If you read the man page to ssh and sshd , you'll find that for PubKey auth, the host must be authorized for this method of auth. That requires the host public key to be present in ~zimbra/.ssh/authorized_hosts and ~zimbra/.ssh/known_hosts
I manually copied the contents of ~zimbra/.ssh/zimbra_identity.pub to these two files and the queue manager started working immediately. no more errors.
Great new feature guys. keep up the good work.
