With Exchange 2010, is it possible to restrict a user's ability to send to certain INTERNAL users ? &nbsp;<br />
<br />
We have a small group of users that should only be able to send to a small specific subset of users and I am not sure how to make this restriction. &nbsp;We do not want these users to be able to email OUTSIDE, or to RECEIVE EMAIL from outside, and we only want them to be able to send (and receive) email from 10 people. &nbsp;We can place these people into a DISTRIBUTION GROUP and I know that we can set the permissions easily on the Distribution group, but how can I limit these users to ONLY be able to send to that distribution group (and it's members individually) ?<br />
<br />
Thanks!

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

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.

Email Servers
