Email Account Error - Temporarily Blacklisted IP address
I'm having intermittent email account errors when accessing my Xfinity account from my second home. I'm using Apple Mail on a Macbook air using wifi connected to the interet. I have full access to the internet, but when my Mail app attempts to connect to my Comcast mail server, I get the message: Online Status - Temporarily blacklisted IP address - try again later. Some emails will come through periodically, but in general there is no email access through the wifi router. I am able to access email on the Macbook when I use a cellular connection via my phones hotspot function.
Any ideas how to keep my wifi IP address from being blacklisted by Comcast?
Thanks in advance.
