What’s New in Exchange 2007 #10 of 15: Transport Changes in Exchange 2007
Posted by our Guest Blogger Peter Bruzzese, trainer at www.cliptraining.com.
If you are a veteran Exchange admin you will notice that some pieces are missing. For example, Exchange 2007 doesn’t require the SMTP Service component of Windows Server IIS. It has its own SMTP transport. SMTP virtual servers are missing from the Exchange Management Console, replaced by Receive Connectors. Receive Connectors are instances of SMTP transport, just like SMTP virtual servers, that are bound to a particular TCP socket – a unique combination of an IP address and TCP port. Similar to SMTP virtual servers, Receive Connectors belong to a server. SMTP Connectors are replaced by Send Connectors, which are for particular SMTP addresses.
What else has changed?
Routing Groups are gone! So, you might be wondering, “How is message routing handled?” Well, in Exchange 5.5 we had sites and site connectors. In 2000/2003 we created routing groups and connectors between those routing groups. In 2007 we simply use the sites and subnets that are already defined within Active Directory. The existing topology is all we use. Messages route within the organization right out of the box with no configuration. If you want to make adjustments you have the flexibility to do so by modifying AD Sites/Site Links for Exchange routing only. When interoperability is needed with legacy Exchange servers all Exchange Server 2007 servers will be installed in a single Administrative Group with a single Routing Group.
