For example, sending a mail to
Jeffrey.Rosen@chicago.exchangeexchange.com has a delivery type of SMTP, and a destination
domain exchangeexchange.com . Exchange routing always tries to find the best match, which is
defined by the number of characters that match to the address space configured on the connector. This
concept is shown in the following table. The best match is Chicago.exchangeexchange.com .

During processing, the Hub Transport decides on the message routing. By default, the site link cost associated
with Active Directory replication is used. This can be overridden by setting explicit Exchange routing
costs. The section ??? Working with Active Directory Sites ??? explains the cmdlets used for this process.
After the route is selected, the message is relayed from the source to the next hop.
Next Hop Selection Process
The next hop selection process is responsible for getting the message as close to the ultimate destination
as possible. There are different scenarios in which direct delivery may not be possible. For example, an
administrator can force all mail delivery through a particular Active Directory site.
Part of the next hop selection process is to determine where the message will queue for delivery.
