SUMMARY

Exchange Server administrators may want to divide an organization into departments for Internet mail, and Exchange Server users may want to receive mail as user_name@department.company.com. An example of this type of Internet address is user1@example.microsoft.com. This article describes how to divide an organization into departments for Internet mail.

MORE INFORMATION

To divide an organization into departments for Internet mail:
  1. Confirm that all users are receiving e-mail messages in the user_name@company.com format. This will confirm that the A record and Mail Exchanger (MX) records are properly configured on the Domain Name System (DNS), which can be local or in the site of the Internet service provider (ISP).For additional information the A and MX records, click the article number below to view the article in the Microsoft Knowledge Base:

  2. In the Exchange Server Administrator program, click Configuration, click Connections, and then double-click Internet Mail Service.
  3. Click the Routing tab, and then click Reroute incoming SMTP mail. Click Add, type the new domain name (department.company.com) and leave the other settings at the default settings. This record looks like the other exiting records (for example, example.microsoft.com).For additional information about adding a routing domain name, click the article number below to view the article in the Microsoft Knowledge Base:

  4. Add an MX record on the DNS with the new domain name (department.company.com). For additional information about the extra A and MX records, click the article number below to view the article in the Microsoft Knowledge Base:

    Confirm that the A and MX records are correct by running the NSLookup utility. Let the DNS replicate with other DNS servers on the Internet. This can take from 24 to 48 hours.
  5. For every mailbox, add a secondary Simple Mail Transfer Protocol (SMTP) address space with the e-mail address of user_name@department.company.com. In the Administrator program, double-click the mailbox to open the mailbox properties. Click the E-mail Address tab, click New, click Internet Address, and then click OK. Type user_name@department.company.com as the e-mail address.For additional information about how to automate this process for several users, click the article number below to view the article in the Microsoft Knowledge Base:

  6. After the DNS replication (24 to 48 hours), test to make sure that the configuration is correct by sending a message to the new SMTP address (user_name@department.company.com), and confirm that the user receives the message.
