Can anyone tell me how I can deny email from a person outside my organization. What I mean to say is, can I keep johndoe@whatever. com from being able to send email to my server? I'm running Exchange 2k. Help, this is getting annoying. I can filter it out with my AV software, but that's not taking care of the larger issue. Any insight would be great. Thanks.
