I would like to modify my Office 365 spamfilter to mark all messages with Authentication-Results: spf=fail as spam.

Before I enable this, I would like to receive an overview of all mails that have passed the spamfilter last week with an fail on the spf record to see or there maybe any legimit emails that will be blocked after I enable this.

Is it possible to generate such a message tracking report (or some kind of other report)?

Since our own domain has an softfail at this moment, i would also generate a report where sender adres equals a specific domain and Authentication-Results: spf=softfail
