cyrus is another node somewhere in your network, to deliver mails to  
the users? But this is only a secondary problem IMO.

As you reinstalled OS X: did you also enable the root account on  
these machines? Othewise we need in. Finder - Go to: Utilities -  
NetInfo Manager. Then "Security - Enable root account"

BTW: I would go for 6.1, if you have to set it up from scratch anyway.
