It's also a good idea to follow through with the instructions (#BL000000 from the Comcast link, below), include full header of the post and content, purpose of the list, etc. I find that sometimes these refusals are quite temporary, and even without action resolve themselves after a few days. But if your list is important, you will want to peruse a few blacklisting sites and follow up with Comcast to ensure continued delivery. Best of luck!
