Exchnage only allows access to an SMTP resource based on IP address, not user account or mailbox.<br />

If you have a fax server, you can assign the SMTP virtual server a connection control to allow only the fax server IP to use the SMTP server.<br />

Assuming you are using Exchange 2K, you can find this under SMTP Virtual Server properties &gt;&nbsp;Access tab &gt;&nbsp;Connection button.<br />
