As is also the case with the other Exchange filtering features, you need to enable Sender ID filtering under the default SMTP virtual server, as can be seen in Figure 5 below. You only have to enable Sender ID filtering on any Exchange server accepting mail from the Internet, or on the first Exchange server located behind another type of Internet facing SMTP server such as SendMail or whatever is used in your particular organization.
After recipient filtering is applied, Exchange checks the resolved sender address (the P2 data from RFC2822 headers) against the Blank Sender. If a match is found, Exchange filters the message based on the options that you configured and no other filters are applied.
