This is really cool. Amazing work. I am looking at running my own mail server out of a Linode instance. It would service a number of our domains and serve to migrate from having web and email live on the same machine at other VPS's. I want to have email serviced from a dedicated instance that does nothing but email for all of our sites. This seems like a better overall strategy but it's been hard to get motivated to get it done due to the amount of work this represents. I have not studied this guide in detail yet but it seems to really take you down the path step by step very nicely. Thanks!
