We are running Exchange server 2007. We have some users who are abusing the system and need to be restricted from sending or reciving internet email yet still be able to correspond with internal people. I have tried checking the require all senders are authenticated and that did not do the trick. I am having a terrible time find info for Exchange 2007 about how to do this.
