Allowing or denying addresses using the inbound sender controls works very

If you deny messages from certain Internet addresses or domains using the
inbound sender controls, the sending server will receive a 554 SMTP
response and will not be allowed to transfer the message. The message is
never accepted by the Domino server, nor is it written to mail.box.
The delivery failure report that's generated when a message is denied using
inbound sender controls is shown in Figure 4-7. Notice the failure reason
provides an SMTP Reply code, 554 along with the reason for the failure, "Mail
from <E-mail address> rejected for policy reasons."

If you deny messages from certain Internet addresses or domains using a
server mail rule, (with the don't deliver message action), as the administrator,
you can choose either to send an NDR (Non-Delivery Report) or to silently
delete the message. The delivery failure report in Figure 4-8 was generated
using a server mail rule. Notice that the reason for failure only indicates
"Message rejected for policy reasons," but does not make note of the sender's
address.
