Backround info: I have an Exchange 2003 server setup on my domain. My ISP is Roadrunner. I have a dynamic IP address.
Problem: More and more ISPs are blocking email from dynamic IPs so I need to find a workaround. I got my username and password from Roadrunner and confirmed that it works by using thier web access mail client. The address of thier smtp server is smtp-server.nyc.rr.com. I setup a smarthost using this address as well as basic authentication in Exchange. However as soon as I make the change I can no longer send out any emails. Eventually I get a bouncback saying that delivery has been delayed.
Question: Is there a better way to setup the smart host? Is there a good company other then my ISP that you could recommend that provides smarthosting services?
