>Firewall? What have you done to try and find out what the problem is? I disable firewall and SELinux on mail server machine and the PIX firewall where the machine connects to outside world allow port 80 and 443 just as before but still the problem persist. I will try to up later the old machine and will check if the web mail becomes accessible and then restore the new machine (this is in production only) again. This is to see if DNS is the culprit, but I doubt it. Any more ideas guys?
