Ahmed, Try tcptraceroute. you can use tcptraceroute utility to trace where is the port 25 blocked. you may need to download a rpm package for tcptraceroute and install it. I have heard that Rogers does not allow running servers on home internet. I believe Bell does. Thanks Pankaj On 1/16/07, Ahmed Mohamed <ajmoham@xxxxxxxxx> wrote:
Thanks Jeremy L. Gaddis and all. I was suspecting all along that the problem might be with outbound port 25 blocked but I was not completely sure. To get around the problem, I have since tried other ports like cyrus2 587. In addition, I configurered SMART_HOST with (`smtp.broadband.rogers.com')dnl (I am not sure if it is correct the one - Rogers folks would'nt tell you). No luck. By the way, does anyone know of CANADIAN ISP provider that allow port-forwarding like mail, http, and the like. Your suggestions are welcome.
