Dave,
When you configure SBS 2003's Exchange 2003 recipient policy to set the xyz.com domain as the primary Email domain (using the Configure
Email and Internet Connection Wizard, usually) the Exchange server is configured to be the primary server for the xyz.com Email address
space. When an SBS User tries to send mail to
who is not a local user), Exchange will attempt to deliver the message to
UserXY's mailbox homed on the server. UserXY's mailbox is not homed on the Exchange server so Exchange will NDR the message to the
originator.
You can solve this problem by configuring Exchange 2003 recipient policy to "Share" the primary address space. For this example, let's use
xyz.com. Some other conditions must be met.
Prerequisites:
1. The Email domain xyz.com is actually being hosted by an ISP's POP3 server.
2. Exchange 2003 is retrieving mail for its own user's from the ISP's POP3 server using the Microsoft POP3 connector for POP3 Mailboxes.
The mail for the other users who use the same POP3 server for their mail is not touched by the POP3 connector.
Configure Exchange Recipient Policy to share the Primary Address Space xyz.com:
1. Open the Exchange System Manager.
2. Click on Recipient Policies.
3. Open the properties of the Default Recipient policy.
4. Click on the Email Addresss (Policy) tab.
5. Note how many SMTP addresses are listed. If there is more than one, select an SMTP address which is not set as the primary (the
primary SMPT address is displayed using Bold letters) and set it as primary. Otherwise, proceed to step 8 below.
6. Select the xyz.com address, click on the Edit button. Uncheck "This Exchange Organization is responsible for all mail delivered to this
address." Click OK.
7. Select the xyz.com domain, set it as primary.
8. If there is only one SMTP address listed in the Email Addresses, add another SMTP address (@abc.net, for example. The "@" symbol
must preceed the address used or the wizard will reject the address entered as invalid.) Ensure that the "This Exchange Organization is
responsible for all mail delivery to this address" checkbox is checked. Click OK.
9. Check the empty checkbox next to the SMTP address @abc.net just entered. Select the @abc.net address, set it as primary. Proceed
to step 6 above and complete steps 6 and 7.
10. Restart the Exchange server services.
11. The Exchange 2003 Server will now send mail sent to users @xyz.com whose mailboxes are not homed on the server to the ISP's POP3
server.
