Within these pages I attempt to document what I am doing to setup an Linux email server that gets user information from a Windows NT server. The main reason for doing this was to get rid of Microsoft Exchange. Not because Exchange wasn't working, though I have encountered problems with it, but because we were not using all of it's features and, being a small company, we really cannot afford it. This does not mean we will not be making the appropriate donations once we settle on the packages we will be using.
