@XfinityDaveL​ Can you post the solution here, or at least give a hint? I'm having the exact same problem - emails from my doctor's web portal are no longer reaching me, not in my spam folder, think they're just being blocked at the ISP level before they even get to my mail account - server with this problem is 104.193.19.19, and I don't find it on any public blacklists, but I almost never get his emails. Even more bizarre, I did get one this morning, but prior to that the last one I got was on 3/6/23 and he sent me a over a dozen emails during those two dates and I got none of them. This kind of inconsistent delivery of email has also occurred with my bank, but it's a different issue - sometimes they go into the spam folder, sometimes they get delivered. Forwarding isn't a solution if an email is blocked before it reaches Comcast's email servers, and it doesn't work for email that ends up in the spam folder either - Comcast spam rules are applied first and no further rules are processed, so I can't whitelist a sender who ends up in my spam folder.
