I am unable to send email to any Comcast customer from my company email. My webhost company has told me that my domain name (i.e.
www.abcpi.com; not my real domain name) has been blocked but not the IP address associated with the domain name (i.e. 208.78.242.185). When you lookup the domain name for 208.78.242.185 you find
webhost.dynadot.com. Is it possible that Comcast can block the name but not the IP address? In other words can they block
abcpi.com but not
webhost.dynadot.com even though the IP addresses are the same? Has anyone else had a similar problem and if so, how did you solve it? I'm getting nowhere with Comcast and their online forms. Thanks!
