GoDaddy's DMARC reports are passing SPF even when the RFC5321.MailFrom and RFC5322.From domains aren't aligned.

Just 0.3% of domains implemented an MTA-STS TXT record. 571 (19.5%) of these domains have implementation errors (see complete list below). Among the valid MTA-STS implementations, 54.3% publish an 'enforce' policy, while 45% have opted for a 'testing' policy. In summary, 1278 domains leverage MTA-STS to fortify their defenses against Man-in-the-Middle (MitM) downgrade attacks.

"If email is subject to the DMARC policy of "reject", the Mail Receiver SHOULD reject the message (see Section 10.3). If the email is not subject to the "reject" policy (due to the "pct" tag), the Mail Receiver SHOULD treat the email as though the "quarantine" policy applies. This behavior allows Domain Owners to experiment with progressively stronger policies without relaxing existing policy."
