Best Exchange configuration for colocation
Posted on 2008-10-07
I manage a network running SBS2003. I have 25 clients using outlook 2003 with Exchange. So far, the network has been relatively simple, with one Exchange server on a single domain managing all mail. We are in the process of collocating some of our internet facing services (web server, SQL) to a data center that will provide better reliability and sustainability. Most of our internal resources will remain at our main office where they are now. We have a few addresses used exclusively by our web services that deliver e-mail based products and notifications. I'm thinking of adding another Exchange server to our network in order to host these addresses at the data center so that they can be afforded the same benefits as our other services there. Since I've never dealt with a multi-Exchange environment, I'm not really sure about the best configuration for my purposes. I've looked into setting up routing groups, but will I be able to designate what server routes specific e-mail addresses in such a configuration? I've also thought about simply moving our single Exchange server to the data center, but I would prefer not to have all of our clients connecting through that link. It will be secure but it's going to increase the overhead bandwidth significantly. Any configuration suggestions?
