Use the options on the Connection dialog box to limit access to the SMTP virtual server by client IP address or domain name. You can grant access to all computers and then make exceptions to this rule by denying access to specific computers. Also, if you deny access to all computers, you still can grant access to specific computers. The following options are available on the Connection dialog box.
