MORE INFORMATION

Configuration

After you install Exchange 2000, the SMTP service is ready to process e-mail. No further configuration is required to send and receive e-mail. The SMTP service is very flexible and can be customized to suit most messaging requirements. All of the steps in this article are performed in the Exchange System Manager.

How to Start Exchange System Manager

  1. On the Start menu, point to Programs, point to Microsoft Exchange, and then click System Manager.
  2. Double-click Administrative Groups.
  3. Double-click First Administrative Group.

    NOTE: If you have changed the name of the default administrative group, expand the appropriate node for that administrative group.
  4. Double-click Servers and find the default SMTP virtual server on any server.

Virtual Servers

This section describes how to configure SMTP virtual servers.

How to Create an Additional SMTP Virtual Server

In most cases, you only need one SMTP virtual server. However, in certain situations (if you host multiple domains and want to have more than one default domain, for example) you can create multiple SMTP virtual servers. When you create an SMTP virtual server, a home directory is automatically created in the Exchange Server MDBData folder.

To create an additional SMTP virtual server:
  1. Click SMTP.
  2. On the Action menu, point to New, and then click SMTP Virtual Server.
  3. In the SMTP Virtual Server dialog box, type a description for your virtual server, and then click Next.
  4. Click the Internet Protocol (IP) address that the virtual server will use, and then click Finish.
NOTE: If you click All Unassigned, this virtual server monitors port 25 of all IP addresses that are not currently assigned to a virtual server by default.

How to Change the IP Address and Port Number

  1. Click the virtual server that you want to change the IP address and port number for.
  2. On the Action menu, click Properties.
  3. On the General tab, click Advanced.
  4. In the Advanced IP address configuration list, click the identity, and then click Edit.
  5. Change either the IP address or the port number so that there is no conflict with any other virtual servers.
  6. Click OK until you close the virtual server properties.
  7. Start the virtual server.

How to Stop, Start, or Pause a Virtual Server

  1. In Exchange System Manager, click the virtual server that you want to stop, start, or pause.
  2. On the Action menu, click either Start, Stop, or Pause, as applicable.
NOTE: If you pause a virtual server, you prevent new client connections but you enable the SMTP service to continue to process existing client connections and deliver queued messages. You can also pause a virtual server to gracefully stop the virtual server without interrupting active connections.

How to Limit Inbound Connections

  1. In Exchange System Manager, click the virtual server that you want to configure.
  2. On the Action menu, click Properties.
  3. On the General tab, click to select the Limit number of connections to check box.

NOTE: Both the Open Database Connectivity Logging (ODBC) and World Wide Web Consortium (W3C) extended log file format have different extended logging properties.

How To Configure ODBC Logging

  1. Create a database that contains a table with the appropriate fields for the logging data. Microsoft Internet Information Service (IIS) includes a Structured Query Language (SQL) template file, which can be run in a SQL database to create a table that accepts log entries from IIS. The file is called Logtemp.sql and is available in the Winnt\System32\Inetsrv folder. The following fields are required:
    • ClientHost: varchar(255)
    • Username: varchar(255)
    • LogTime: datetime
    • Service: varchar(255)
    • Machine: varchar(255)
    • ServerIP: varchar(50)
    • ProcessingTime: int
    • BytesRecvd: int
    • BytesSent: int
    • ServiceStatus: int
    • Win32Status: int
    • Operation: varchar(255)
    • Target: varchar(255)
    • Parameters: varchar(255)

How to Enable Message Filtering (Turf List)

The "turf list" is set on the Filtering tab of the Message Delivery Properties dialog box. You can gain access to this dialog box by using Global Settings in Exchange System Manager. When turf list filtering is enabled on an SMTP virtual server, e-mail received from anyone on the turf list is filtered out. For example, if an SMTP virtual server is connected to the Internet, you can filter e-mail from one or more outside users who are trying to gain access to the organization by using a particular IP address. If, however, a different IP address is configured on the same virtual server (for example, for internal users who connect to the Internet), you may need to enable filtering for connections on this IP address. This is why turf list filtering is set in the Identification dialog box.

To enable message filtering on a virtual server:
  1. In Exchange System Manager, click the virtual server that you want to configure.
  2. On the Action menu, click Properties.
  3. On the General tab, click Advanced.
  4. In the Advanced dialog box, type the IP address to which you want the filter applied, and then click Edit.
  5. In the Identification dialog box, click to select the Apply Filter check box, and then click OK.
  6. Click OK, and then click OK again to close the virtual server properties.
