Microsoft 2004 Manuel D’Utilisation

Create the SMTP Server Publishing Rules 

The SMTP Message Screener works together with SMTP Server Publishing Rules. Each 
SMTP Server Publishing Rule can be configured with a custom set of SMTP Message 
Screener parameters. This allows you to create different e-mail screening policies for the 
inbound and outbound SMTP relays. Different SMTP Message Screener configurations allow 
you to block different e-mail messages coming into the network versus what gets blocked on 
the way out. 

Perform the following steps to create the Server Publishing Rule that listens on the external 
interface of the ISA Server 2004 firewall: 

1. Open 

the 

Microsoft Internet Security and Acceleration Server 2004 management 

console and expand the server name in the left pane of the console. Click on the Firewall 
Policy node. 

2.  Right click the Firewall Policy node and point to New. Click Server Publishing Rule. 

3. On 

the 

Welcome to the New Server Publishing Rule Wizard page, enter the name for 

the rule in the Server publishing rule name text box. In this example, we will name the 
rule Inbound SMTP Relay, as this rule will use the external interface of the ISA Server 
2004 to accept incoming mail to be relayed. Click Next. 

4. On 

the 

Select Server page, enter the IP address on the Internal interface of the ISA 

Server 2004 firewall that you want to publish. Enter 10.0.0.1, which is the primary IP 
address on the Internal interface of the ISA Server 2004 firewall machine. Click Next. 

5. On 

the 

Select Protocol page, select the SMTP Server protocol from the Selected 

protocol list. Click Next.
