I run exchange 2003, and when setting up a linux webserver for the first time and configuring sendmail for it's users i came across a feature that drops mail from unresolvable domain names. Thats a great way to cut down on spam. Is there a similar feature for MS Exchange 2003? If so give me the details =)
