Hello I am new to Plesk and have installed a Plesk Expand box a Windows box and a Unix box.   I would like to have a primary and secondary dns server system functioning on the Expand and the Unix boxes and also centralized mail.   My question is what additional software packages do I require in order to facilitate this setup and how do I install them ?   I tried installing the Plesk unix server on the Expand server but it complains that it cannot do that. 
Thanks in advance.
