Prior to my departure from my old job, I left one thing undone on the 'ol Small Business Server 2000, that was how to use and resolve addresses with SMTP Server. Everyhting was getting resolved at the outside ISP. After a 4 hour crash course, self-taught, I learned not only how to route in house addresses, but how to route the others out to the appropriate ISP for resolution. The old place used to get the same message I saw yesterday, "Message Undeliverable." Now I know how to route it all through Exchange and not worry about that old half-ass way to dodge the server. It is the way it should run, glad I finally learned one of the missing pieces of what I left undone at the old place.
Yesterday left quite a pit in my stomach, when I had no solution for the problem. Today at least, I not only had a solution, but a better solution for the place, and more options for them to use later, if they ever choose to. I left it better off that it was when I started on it, good.
