I had a home office with a SBS 2003 Server and a handful of clients. I also have a website hosted by a typical web host. Since I had a residential broadband connection with a dynamic IP (and port 25 blocked..) I had my outbound email relayed from Exchange to my host's email server. My incoming was setup using the POP connector and pulling the email every 15 minutes.
Now I have moved into a commercial property. I now have business class internet service with a static IP address. When I first sent an email, it was rejected with a 550 error saying that the relay had to be authenticated. I removed the smart host and mail is sending fine now.
That got me to thinking.. could I (well.. I guess I know I could, maybe should I?) forgo the host's email server and only use my server? I have a couple of business reasons that I'd like to have my email immediately and not wait for the POP connector to retrieve it. But I'm also concerned about down time. I've had almost none, but I've seen Murphy hanging around quite a bit lately.
If dropping the host's server is a good idea, what are the rough steps I need to do in order to implement that? Do I have them change the DNS records? Do I need to do anything to the server?
Thanks in advance for your help!
