email problems

Some legitimate incoming emails, including password resets and contractor correspondence, never appear in Inbox or Spam. This has happened intermittently for approximately six months.

I have checked storage, filter rules, blocked senders, and safe-list settings. Comcast now retains copies of forwarded messages.

Please escalate this for a server-side email delivery investigation. For the example below, can you determine whether your servers accepted, rejected, deferred, or filtered the message, and provide any available delivery status or rejection reason?
