 We get lots of spam lately (asually viagra, amazon etc) that have one of our exchange users as recipient and sender. &nbsp;Is there an easy way to block external mail that says it comes from our domain and not stop internal traffic from our domain.<br />
All of our users are either local or use webmail no SMTP users.<br />

Thanks
