I think you have to switch to a business class service with Comcast to get a static IP address that is really static. What they might do if it isn't business class is a MAC reservation within the DHCP scope for an address, this would cause your mail to get bounced as a dynamic address. The address would still be in the scope that is dynamic. They use the MAC address on your router and tell the scope the address associated with this MAC can't be given to any other MAC address. Many businesses use reservations within a DHCP scope to keep from having static addresses on all their servers, it's easier to manage. Sam.
