If you attempt to send mail using a dynamic IP, it is going to be blocked by most MTAs since it fails reverse DNS checking. I am assuming that you are attempting to bypass your ISP. You have to get a static IP from your provider. With port 25 presently blocked, you might consider using something like mail relaying/forwarding from a service like DYNDNS: http://www.dyndns.com/. -- Gerard
