SUMMARY
This step-by-step article describes how to configure remote domains.

You can set unique delivery requirements for a specific remote domain by adding a domain and configuring it accordingly. For example, you can set a predetermined delivery route, set authentication, and require that TLS encryption be used on all connections to the domain.

Setting a Route Domain
If the remote domain is not specifically configured, Microsoft SMTP Service does not use any of these operations when delivering to this domain. However, it does complete a normal DNS lookup.

You can specify a delivery path that may be faster and less expensive than a direct link. Type the name or IP address of the server through which you would like to route messages for this remote domain.

To Designate a Route Domain

 * 1) Expand the appropriate SMTP virtual server node.
 * 2) Right-click the Domains node, point to New, and then click Domain.
 * 3) Use the New Domain Wizard to create a remote domain. In the Details pane, right-click the new remote domain, and then click Properties.
 * 4) On the General tab, under Route domain, click Forward all mail to smart host, and then type the name or IP address of the server through which you would like to route messages for this remote domain. This setting overrides the smart host setting on the Delivery tab.

NOTE: You can identify the smart host by FQDN or an IP address (but if you change the IP address you would have to change it on every virtual server as well). If you use an IP address, enclose it in brackets [ ] to increase system performance. Microsoft SMTP Service checks first for a server name, then an IP address. The brackets identify the value as an IP address, so the DNS lookup is bypassed.

Enabling TLS Encryption for a Remote Domain
You can set up alias domains that use the same settings as the default domain. Messages that are received by the Microsoft SMTP Service for the alias domain are placed in the Drop directory that is designated for the default domain.

If you choose not to use TLS encryption for the SMTP virtual server, but you select the TLS encryption check box for this remote domain, SMTP will use TLS encryption when it connects to the remote domain. Domain configurations always override the virtual server configurations.

To Enable TLS Encryption for a Remote Domain

 * 1) Expand the SMTP virtual server, and then click Domains.
 * 2) In the Details pane, click the remote domain you want to change. On the Action menu, click Properties.
 * 3) On the General tab, click Outbound Security to open the Outbound Security dialog box.
 * 4) Click Windows security package.
 * 5) Type the Windows account and password.
 * 6) Click to select the TLS encryption check box, and then click OK.

NOTE: If the remote domain does not support TLS encryption, all messages will be returned with an NDR.

Authentication for a Remote Domain
You can configure the SMTP virtual server to provide the authentication credentials that are required by the remote domain. There are two types of authentication available: basic (clear text) and Windows Security Package.

You can override the SMTP virtual server authentication by selecting a configuration option.
 * If messages are commonly sent to multiple addresses, disable authentication for the SMTP virtual server.

NOTE: If attempts to deliver messages to an address do not work because of authentication requirements, add a remote domain for the address. Then enable authentication for the domain at the same level that is required by the server.
 * If you disabled authentication for the SMTP virtual server and attempts to deliver messages to an address do not work because of authentication requirements, add a remote domain for the address, and then enable authentication for the domain at the same level that is required by the server.

NOTE: Determine what level of authentication is required to connect. Then enable authentication for the SMTP virtual server by using the same level. If you want to then send messages to other addresses, set up remote domains and set different authentication options. If you use this option, it is likely that the account name that is used is the one that identifies the computer that is set up as the smart host.

To Disable Authentication for Outgoing Messages
You can disable authentication, which is the default option.
 * 1) Expand the SMTP virtual server, and then click Domains.
 * 2) In the Details pane, click the remote domain you want to change. On the Action menu, click Properties.
 * 3) On the General tab, click Outbound Security to open the Outbound Security dialog box.
 * 4) Click Anonymous access, and then click OK.

back to the top

To Set Basic Authentication for Outgoing Messages
With the basic option, the account name and password of the server you're connecting to is transmitted in clear text.
 * 1) Expand the SMTP virtual server, and then click Domains.
 * 2) In the Details pane, click the remote domain that you want to change. On the Action menu, click Properties.
 * 3) On the General tab, click Outbound Security to open the Outbound Security dialog box.
 * 4) Click Basic authentication.
 * 5) Type the user name and password of the computer to which you are connecting.
 * 6) Click OK.

back to the top

To Set Windows Security Package for Outgoing Messages
The Windows Security Package option requires a Windows account name and password.
 * 1) Expand the SMTP virtual server, and then click Domains.
 * 2) In the Details pane, click the remote domain that you want to change. On the Action menu, click Properties.
 * 3) On the General tab, click Outbound Security to open the Outbound Security dialog box.
 * 4) Click Windows security package.
 * 5) Type the Windows account name and password.
 * 6) Click OK.

Configuring ATRN for a Remote Domain
The Microsoft SMTP Service can hold mail for clients that connect periodically to download messages. In this case, the client issues an ATRN command. The remote SMTP service then starts sending messages to the ATRN domain.

You can create a remote domain for an address that periodically reviews messages and enable ATRN for the domain.

back to the top

To Enable ATRN Transmissions for a Remote Domain

 * 1) Expand the SMTP virtual server, and then click Domains.
 * 2) In the Details pane, click the remote domain that you want to change. On the Action menu, click Properties.
 * 3) Click the Advanced tab, and then click to select the Queue messages for remote triggered delivery check box.
 * 4) Click Add or Remove as necessary to select Windows 2000 accounts that will be allowed to use the ATRN command in this domain.
