In case my Private message didn't come across to the community manager since I hadn't posted to the forums yet, this is me making a generic post stating that I need to have a Reverse DNS PTR record updated. I sent a PM with the details to Comcast_Jessie so hopefully they see that and respond.
(((Oops, just realized I put this in the wrong sub forum. I'll post this over there as well. Feel free to remove this one)))
