Temporarily blacklisted IP Address

I cannot reliably access my Comcast email via Gmail. When I go to Gmail Settings/Accounts and Import/Check Mail from other accounts, I get a message: Authentication error. Mail from this account has not been retrieved since When I look at the details for this I see: Authentication error. Server retu

The error message is coming from the Comcast email server indicating that the Gmail IP address is blacklisted and so Comcast will not allow Gmail to fetch my emails. There is a workaround for the problem. In Gmail, go to Settings -> See All

Yes, I have gone to xfinity website to make sure access to third party emails is turned on. This is not the problem.

I know how to log into my Comcast account to read email and sometimes do. But much prefer to use gmail as my mail client.
