Emails from my private domain going to spam

I have a domain who's email is hosted through Microsoft/Office 365. As of last week, email is being regularly delivered to the spam folder of @comcast.net email addresses. DKIM and SPF are both properly configured. Here are sample email headers of a piece of email delivered to the spam folder.
