I am no longer able to receive emails from the following senders:
I have completely turned off spam filtering. I have added all three addresses to My Address Book.
My husband also has a comcast email address and he receives the emails fine. Additonally, he can see my address included in the To: list. I had no problems receiving emails from these senders prior to a couple of months ago.

Unfortunately, I have not been able to resolve this issue. I called Comcast security, and they were unable to see any of the emails being blocked on their end. I have validated with the senders that the are in fact sending to the correct address.
I just opened a gmail account and started sending mail to there. Very frustrating.
Thank you for getting back to me. I am very frustrated, too. Quickbooks and lots of other applications use software called SendGrid to send emails. The problem could be with SendGrid, althought they deny. I will let you know if I learn anything more. Someone else on the Xfinity Forum had the same problem and managed to get it resolved. I have opened up a case with Xfinity and keep trying to communicate with both Quickbooks and SendGrid. I am also not getting emails originated by an application called Booker.
My problem was solved. It turned out I was on a "suppression list" in an application called SendGrid which is used to send invoices from Quickbooks. Contact email@example.com. Sendgrid claimed I marked an email from QuickBooks as spam which threw me on the list. I have no recollection of doing that. I don't know how that could have happened. But it did.
