The information in this article applies to:


 * Microsoft Exchange 2000 Server

SUMMARY
This article describes how to configure a Simple Mail Transfer Protocol (SMTP) connector on Exchange 2000 Server. The SMTP connector connects Exchange 2000 to the Internet.

Hardware Requirements

 * Intel Pentium 166 Megahertz (MHz) or faster
 * 128 Megabytes (MB) RAM or more
 * NTFS partition with at least 4 gigabytes (GB) of available disk space for Microsoft Exchange 2000 Server

Software Requirements:

 * Microsoft Windows 2000 Server
 * Microsoft Exchange 2000 Server

Installation Requirements:

 * By default, Microsoft Internet Information Services 5 (IIS) is installed with Windows 2000 Server. Check that both Network News Transfer Protocol (NNTP) and Single Mail Transfer Protocol (SMTP) have been installed.
 * A Domain Name System (DNS) server is available for your domain.
 * Microsoft Exchange 2000 Server is installed on a computer that is a member of a domain and not in a workgroup.
 * Exchange 2000 System Manager is configured to group the servers by Administrative and Routing Groups.

How to Configure the SMTP Connector

 * 1) Click Start, point to Programs, point to Microsoft Exchange, and then click Exchange System Manager.
 * 2) In the left pane of Exchange System Manager, expand the administrative group that you want, and then expand the Routing Groups container tree.
 * 3) Expand the routing group for which the connector is to be created.
 * 4) In the right pane of Exchange System Manager, right-click Connectors, click New, and then click SMTP Connector.
 * 5) On the General tab, type a name for the connector in the Name box.
 * 6) If appropriate, click to select the Forward all mail through this connector to the following check box. In the Smart Host box, type the name of the target server you want all messages that use the connector to go to.

NOTE: Do no use smart hosting if you want routing; otherwise, the SMTP service will redirect the message to the smart host.
 * 1) On the General tab, click Add to select the local bridgehead for the connector.
 * 2) In the Add SMTP member(s) to Bridgehead box, click Add, click the SMTP virtual server (local bridgehead) that will manage the outgoing messages, and then click OK.
 * 3) On the Address Space tab, click Add.
 * 4) In the New Address Space box, double-click SMTP.
 * 5) In the Internet Address Properties box, click the General tab. Type the address of the domain that is to use the connector in the E-mail domain box, and then click OK.

NOTE: You may use the asterisk (*) wildcard at the beginning of the address only; no wildcards are allowed within the address. For example, to route a message to user@server.site.com, set the address space to be *.server.site.com, *.site.com, *.com, or *, any of which match the domain portion of the message's address.
 * 1) Assign a cost to the connector by typing a number between 1 and 100 in the Cost box.
 * 2) Click OK.
 * 3) On the Address Space tab, click to select either the Entire Organization check box or the Local Routing Group check box to set the scope of the connector.
 * 4) In the Connector Properties box, click OK.

Additional Configuration Information
In addition to the basic connector setup, you may want to add special restrictions and options for delivery and content for the connector.

Delivery Restrictions
During the setup of an SMTP connector or when you access the properties for an SMTP connector, you can see a Delivery Restrictions tab. On this tab you can specify who is allowed access to this connector. By default, the connector accepts messages from everyone.

To access the properties of the SMTP connector:

On the Start menu, point to Programs, point to Microsoft Exchange, and then click System Manager.

Double-click Administrative Groups, and then double-click First Administrative Group.

Double-click Routing Groups, double-click First Routing Group, and then double click Connectors.

Right-click your SMTP connector, and then click Properties. On the Delivery Restrictions tab, the default is set to Accept messages from everyone. You can also choose to reject messages from everyone.

To restrict specific individuals from using the connector:

 In the Reject messages from box, click Add. In the Select Recipient box, select the recipient that you want to restrict, and then click Add. Click OK.

To add specific users to the connector:

 In the Accept messages from box, click Add. In the Select Recipient box, select the user that you want to add, and then click Add. Click OK.

Content Restrictions
Use the Content Restrictions tab to specify whether the connector restricts messages based on their priority. You can specify three priorities: high, normal, and low. By default, a connector allows all message priorities.

To access the properties of the SMTP connector:

On the Start menu, point to Programs, point to Microsoft Exchange, and then click System Manager.

Double-click Administrative Groups, and then double-click First Administrative Group.

Double-click Routing Groups, double-click First Routing Group, and then double-click Connectors.

Right-click your SMTP connector, and then click Properties.

On the Content Restrictions tab, all allowed priorities are checked, by default. You can click to clear the check box of any of the priorities. If you do so, messages with those priorities are not accepted by the connector.


 * You can configure Exchange 2000 to allow or deny system or non-system messages. System messages are any messages created by Exchange 2000, while non-system messages are all other messages.
 * You can configure Exchange 2000 to only allow messages less than a specific size (in kilobytes).

Delivery Options
The Delivery Options tab is a new addition to the SMTP connector and provides two scheduling features: scheduling the times when the connector is available, and scheduling the times when the connector is available for messages larger than a particular, specified size.

To open the properties of the SMTP connector that you have set up, right-click the connector stub, and then click Properties.


 * On the Delivery Options tab, the connection time is set to Always Run by default. You can change this setting by choosing all the options provided in the drop-down list, or you can create your own custom schedule by clicking the Customize button.
 * You can also click to select the Use different delivery times for oversize messages check box. If you select this option, you can set the size that defines an oversized message (default value: 2000 KB).

Advanced
You can set outbound security, ETRN/TURN, and HELO versus EHLO on the Advanced tab. The default settings are usually what an average installation uses, and there is little need to change settings on this tab.
