Open the admin client. Goto messaging - Select configurations. Edit the current config. On the Restrictions and controls tab, select SMTP inbound controls. on the top part "allow messages from external internet domains to be sent to the following internet domains". Place any domains you control here. Any not listed here will not be allowed through. You will need to go into the messaging tab of the admin client to clear out the debris thou.
