How to Use Internet Mail Wizard
You can use Internet Mail Wizard to configure Exchange Server to send, receive or send, and receive Internet mail. Remember, if your messaging environment is large or complex, you cannot use Internet Mail Wizard. Instead, you must manually configure Exchange for Internet mail delivery.
Exchange Server 2003 implements a new version of Internet Mail Wizard that helps you configure Internet mail connectivity in Exchange Server 2003 or Exchange 2000 Server. Using Internet Mail Wizard, you can configure an Exchange server to send Internet mail, receive Internet mail, or send and receive Internet mail. Furthermore, using Internet Mail Wizard means that you do not have to manually configure the SMTP connector and SMTP virtual server. Internet Mail Wizard automatically creates the necessary SMTP connector for outgoing Internet mail and configures your SMTP virtual server to accept incoming mail.
Note
If you have already set up SMTP connectors, modified the IP address or port number of your default SMTP server, or created additional SMTP virtual servers on your Exchange server, you cannot run Internet Mail Wizard unless you reset your server configuration to its default state.
Important
Internet Mail Wizard is intended primarily for small and medium size companies with less complex environments than large enterprise companies. If you have a complex or enterprise messaging environment, you should manually configure Exchange for Internet mail delivery. For more information about manual configuration, see "Manually Configuring Your Exchange Server for Internet Mail Delivery" later in this chapter.
Before You Begin
Before you perform the procedure in this topic, read Connecting Exchange to the Internet.
The following permissions are required to perform this procedure:
- Member of the local administrators group and a member of a group that has had the Exchange Administrators role applied at the administrative group level.
Although Internet Mail Wizard automatically configures your SMTP virtual server and SMTP connector for Internet mail delivery, you must complete the tasks that are shown in this table before you run the wizard.
Prerequisites to running the Internet Mail Wizard
| Step | Task | Notes |
|---|---|---|
1 |
Verify that SMTP is installed correctly on your Exchange server. |
For more information about verifying that SMTP is installed properly, see How to Load Exchange SMTP Properly. |
2 |
Verify that DNS is correctly configured. |
To send Internet mail, the DNS server that is used by your Exchange server must have the ability to resolve external addresses. To receive Internet mail, you must have a mail exchanger (MX) resource record pointing to the IP address of the SMTP virtual server receiving inbound Internet mail. Additionally, your mail server must be accessible from the Internet so that other DNS servers can resolve the MX record. For more information about verifying that DNS is correctly configured, see "Configuring DNS for Outbound Mail" in Verifying DNS Design and Configuration. |
Procedure
To use Internet Mail Wizard
In Exchange System Manager, right-click your Exchange organization, and then click Internet Mail Wizard.
Note
To run Internet Mail Wizard, you must use the version of Exchange System Manager that comes with Exchange Server 2003.
Follow the instructions in the wizard to perform the configuration tasks that are necessary to configure Internet mail delivery. The configuration tasks are documented in the following tables:
Using Internet Mail Wizard to configure the sending of mail
Using Internet Mail Wizard to configure the receiving of mail
Using Internet Mail Wizard to configure the sending of mail
Task Notes Select an Exchange server within your organization that will send Internet mail.
You cannot run the wizard on a server on which you have already set up SMTP connectors or created additional SMTP virtual servers. You can only use the wizard to designate Exchange 2000 or later servers.
Designate a bridgehead server.
This is the Exchange server and the SMTP virtual server on this server. The wizard creates an SMTP connector on the selected SMTP virtual server and Exchange server. The outbound bridgehead server handles all mail that is sent through this connector.
Configure an SMTP connector to send Internet mail.
Internet Mail Wizard guides you through the process of configuring your SMTP connector. The options that are available to you include the following:
You can allow Internet mail delivery to all external domains, or you can restrict Internet mail delivery to specific domains.
You can specify whether the SMTP connector sends outbound mail using DNS to resolve external domain names, or whether it uses a smart host that assumes responsibility for resolving external names and delivering mail.
Verify that your SMTP virtual server is not open for relaying.
With open relaying, external users can use your server to send unsolicited commercial e-mail, also known as spam, which may result in other legitimate servers blocking mail from your Exchange server. If you prevent your server from relaying, only authenticated users can send mail to the Internet using your server.
Using Internet Mail Wizard to configure the receiving of mail
Task Notes Select an Exchange server within your organization that will receive Internet mail.
You cannot run the wizard on a server on which you have already set up SMTP connectors or created additional SMTP virtual servers. You can only use the wizard to designate Exchange 2000 or later servers.
Configure your SMTP server to receive Internet mail.
To receive incoming Internet e-mail messages, the server must have only one SMTP virtual server, and that virtual server must have a default IP address of All Unassigned and an assigned TCP port of 25. If more than one SMTP virtual server exists on the Exchange server, or if the IP address or the port assignment is different than the default settings, the wizard will not continue. You can then either restore the Exchange server to its default configuration and rerun the wizard, or you can use Exchange System Manager to configure Exchange manually.
Verify that your SMTP virtual server allows anonymous access.
Other servers on the Internet expect to connect anonymously to your SMTP virtual server. Therefore, anonymous access must be permitted on your SMTP virtual server. If anonymous access is not configured, the wizard guides you through enabling anonymous access.
Configure your recipient policies with the SMTP domains for which you want to receive inbound mail.
The SMTP domains for which you want to receive Internet mail are configured in Exchange System Manager in Recipient Policies. You must have a recipient policy configured for every SMTP domain for which you want to accept Internet mail, and Exchange must be authoritative for this domain, or have a connector for this domain to which relaying is permitted. If your default recipient policy contains the correct mail domain for your organization, use this policy.
If you have created multiple recipient policies in Exchange System Manager, you cannot use the wizard to create additional recipient policies. In this case, if you need to add or modify your recipient policies, you must use Exchange System Manager. For more information about how to configure recipient policies manually, see "Configuring Recipient Policies" in Manually Configuring Your Exchange Server for Internet Mail Delivery.
Remember that your DNS servers must be able to resolve all domain names either locally or by using configured forwarders in DNS. If your DNS server is unable to resolve any domain names, Exchange cannot process mail.
