 DNS Changes: 1) Add the host names to your domain for the three IP's, such as RELA01, ASSP01, and EXCH01 and assign the three IP addresses respectively. As described below, RELA01 is the MTA, ASSP01 is obvious, as is EXCH01. 2) Using the DNS registered names instead of IP addresses allows for ease of a server move, or failover server, in the future without the need for reconfiguration of ASSP.

 Exchange Settings - Final 1) Disable outbound connector on port 25 in ADMIN interface.

+
+
+## Configuring ASSP for Exchange 2000 single server implementation
+
+While it will work its not really necessary to have a second separate SMPT server. You can add a new SMTP Virtual server under Exchange admin. Incoming: Internet->ASSP(25)->Default Virtual SMTP Server(225) Outgoing: Default Virtual SMTP Server(225)->ASSP(25)->ASSP Relay SMTP Virtual Server(125)->Internet 
+
+Mail Routing: 
+
+Incoming Internet->ASSP->Default SMTP Virtual Server 
+
+Outgoing Default Virtual Server->ASSP->Relay SMTP Virtual Server->Internet 
+
+Overview: This explains how to setup ASSP on an Exchange 2000 server in a single server implementation. This implementation utilizes 2 SMTP virtual servers setup in Exchange 2000. Step 1: Assign 3 IP addresses to your Exchange server (I'm assuming you know how to do this). In this example we will be using the following addresses: 10.5.200.2 This is the inside address that ASSP listens on. It is also the address that the firewall routes SMTP to and the address of the Default SMTP Virtual Server. 10.5.200.3 This is the address of the SMTP Virtual Server used by ASSP to route mail to the internet 10.5.200.4 This is the address ASSP uses to accept connections from your exchange server. This will be your smart host. 
+
+Step 2: We will need to modify the Default SMTP Virtual Server and create a new virtual server. These servers will operate on ports other than the default 25. In this example we will be using 125 & 225\. ASSP should not be running. If it is stop it. 
+
+Open Exchange System Manager and expand the Servers node. Then expand the server node you are going to work on. Expand the Protocols node and click on SMTP. In the result pane, right click on the Default SMTP Virtual Server and select Properties. 
+
+In the IP address drop down, select the original IP address for your server. In our example this is 10.5.200.2. 
+
+Click the Advanced button, then click the IP address in the list and click Edit. Change the port to 125. Click OK, then Apply and OK. 
+
+Now, right click in the white space in the result pane and select New SMTP Virtual Server. 
+
+In the Name Field give this server a name. I used "ASSP Relay Host" click next. Now select an IP address from the drop down list. In our example we'll use 10.5.200.3. Click finished. (you will see a question mark on the new server) 
+
+Now right click on the new virtual server and choose Properties. Click Advanced and change the port to 225. Click Ok and OK. 
+
+Right click on both Virtual servers and stop them. This will prevent them from colliding with ASSP if there is an interface:port conflict. 
+
+Step 3: Install ASSP if you have not already done so. 
+
+Start ASSP from the command line. (we will start the service later). perl assp.pl 
+
+Open the Configuration web page. http://localhost:55555 
+
+Click "Show Advanced Configuration Options, scroll to the bottom and click Apply Changes. 
+
+Now, in the SMTP Destination enter the IP:port of your Default SMTP Virtual Server. In our example. 10.5.200.2:125 
+
+Click As a Service if it's not already checked. 
+
+Change the Listen Port to the IP:port that incoming SMTP connection will be made on. Example. 10.5.200.2:25 
+
+Enter an alternate if you like. Remember to change your password. 
+
+Under Relaying make these changes. 
+
+Add your local subnet to the Accept All Mail field. Example: 10.5. Enter your local Domains 
+
+In Relay Host enter your ASSP Relay Virtual Server. Example 10.5.200.3:225 In Relay Port enter the 3rd address we created on port 25. Example 10.5.200.4:25 
+
+Configure all other parameters as you see fit and click "apply changes". 
+
+Shut down ASSP. 
+
+Start the ASSP Service. 
+
+Step 4: In your local DNS (local not public) enter a host name for your Relay Port IP address. I called mine smarthost. As of Service Pack 3 Exchange will no longer allow you to enter an IP address for the smart host. 
+
+In Exchange System Manager right click on the Default Virtual Server and choose properties. Click the Delivery tab, and then click the Advanced button. In the Smart Host field enter the FQDN of your smart host virtual server created above. Example: smarthost.domain.com 
+
+Click OK, Click OK. 
+
+Start both Virtual SMTP servers. 
+
+If any of the servers fail to start you have an address:port conflict somewhere. Most likely ASSP is colliding with one of your virtual servers. 
+
+This configuration should work fine for small to mid size organizations. Larger organizations should separate these services on different boxes. I've followed your instructions to the T but mail is still going out through the Default SMTP Virtual Server. I came to that conclusion by looking at the Queues under the Default SMTP Virtual server. With the configurations you outlined, shouldn't mail flow out through the ASSP Relay Host/Virtual Server? eric.mallo
