I seen those solutions but which would be a Microsoft recommended solution you think? &nbsp;I can do it through ADManagment but we will need another 5 licenses and that a 1000 more.

<div>
Use RBAC option in Exchange 2010. &nbsp;That is the recommended method.

<div>
They provide different solutions for different causes - the best recommendation is to look at which is your cause and the correlating solution. It sounds like <b>Cause 1/Solution 1 </b>would fit your description but again you know your environment best.

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.
