SYMPTOMS
If you are using an Internet Mail Service and have restrictions set to either This Site or This Location, you may find that mail is incorrectly routed. This occurs in the following circumstances:
 * You have an Exchange Server site that is geographically split with an Internet Mail Service in each site. Each server has the Server Location property set. The address space is "SMTP:*", but this has a restriction of "location."
 * You have two or more Exchange Server sites linked together and fully replicated. Each site has an Internet Mail Service and the address space is "SMTP:*", but this has a restriction of "site."
 * The expected behavior is that a message sent by a user in either the same site or that Internet Mail Service should send same location as the Internet Mail Service. However, the message is routed to a different Internet Mail Service in another site or location, and then sent out.



CAUSE
The routing logic in the Internet Mail Service is not honoring the site or location restrictions.



RESOLUTION
To resolve this problem, obtain the latest service pack for Exchange Server 5.5. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

191014 XGEN: How to Obtain the latest Exchange Server 5.5 Service Pack



WORKAROUND
A workaround to this issue is to set the restrictions to be organization-wide. However, this may not be suitable in every circumstance.



STATUS
Microsoft has confirmed that this is a problem in Microsoft Exchange Server version 5.5. This problem was first corrected in Exchange Server 5.5 Service Pack 4.
