Configuring a Smart Host on a SMTP Virtual Server

 

Problems may occur if you set the smart host at the virtual server level, rather than at the SMTP connector level. When you configure the smart host at the virtual server level, consider the following restrictions:

Note

The following smart host settings are located in the Advanced Delivery dialog box. To access this dialog box, in <Your Outbound SMTP Virtual Server> Properties, on the Delivery tab, click Advanced.

  • If your Exchange organization contains more than one computer running Exchange, you should not type any data in the Smart host box. Mail flow between servers may not work.

  • If an IP address is listed in the Smart host box, it should be enclosed in square brackets, for example, [10.0.0.1].

  • If an IP address is listed in the Smart host box, verify that it does not match the IP address of this Exchange server.

  • If a name is listed in the Smart host box, it should be a FQDN. For example, "Server Name" is not a FQDN; however, servername.contoso.com is a FQDN.

  • If a name is listed in the Smart host box, it should not be the FQDN of this server.

  • If you do not have a smart host within your network, contact your ISP to find out what IP address or FQDN you should enter here.

  • If you do enter a smart host, select the Attempt direct delivery before sending to smart host check box. Selecting this check box may help reduce queuing on this server.

  • Using multiple smart hosts and load balancing requests across them requires a specific configuration.

Configuring Advanced Settings

This section explains how to configure some of the advanced settings that control Internet mail delivery. Although these settings are not essential for mail flow, they can assist you in performance tuning, controlling access to your SMTP virtual servers, and many other areas.

Specifically, you will learn how to:

  • Configure advanced inbound settings.

  • Configure advanced outbound settings.

  • Configure advanced settings on the SMTP connector.

  • Configure the notification of delivery reports.

For detailed instructions about configuring access controls and security settings, see the following topics:

Configuring Advanced Inbound Settings

This section shows you how to configure advanced settings for inbound mail. Specifically, you will learn how to:

  • Configure access controls and other security settings.

  • Configure message filters.

  • Set limits for incoming messages.

For detailed instructions, see the following topics:

Configuring Advanced Outbound Settings

This section shows you how to configure advanced settings to control outgoing mail. Specifically, you will learn how to configure Internet mail message formats, outbound message limits, and advanced connector settings.

Configuring Advanced Settings on the SMTP Connector

The SMTP connector offers several configuration options, which you can use to tailor your specifications for e-mail messages that are routed through this server. With the exception of message size limits, the settings on the SMTP connector override the settings on the SMTP virtual server. In this case, the lowest size limit is enforced.

In this section you will learn how to perform the following tasks:

  • Specify delivery restrictions.

  • Set a connector schedule for connecting to a network service provider.

  • Set content restrictions on an SMTP connector.

  • Configure how non-delivery reports are handled.
