At our company we have starting getting a problem with spam maessages. Although our inbound e-mails are scanned by an external company first and then forwarded on, an examination of the headers of the spam reveal that they are bypassing the scanning at appearing directly on the public address of our Exchange 2000 server. I have the IP addresses of the external filters so in theory what I need to do is block all inbound SMTP traffic at the firewall unless it is coming from these two addresses.<br />
<br />
However for operational reasons, I'd rather get the Exchange server to do this if possible. I don't mind what happens to mail from 'unwanted' addresses as long as the SMTP packets get dropped. Is it even possible to do this from within Exchange and if so how?<br />
<br />
Many thanks

Blocking Inbound SMTP Traffic to Exchange

Windows 2000 is an operating system for use on both client and server computers. It is the successor to Windows NT 4.0, and is the last version of Microsoft Windows to display the "Windows NT" designation. Four editions of Windows 2000 were released (Professional, Server, Advanced Server, and Datacenter Server) that shared a core set of features, including many system utilities such as the Microsoft Management Console. All versions of the operating system support NTFS 3.0, Encrypting File System, as well as basic and dynamic disk storage. The Windows 2000 Server family includes support for Active Directory services, Distributed File System and fault-redundant storage volumes.
