OK, I'll bite.

"DMARC saves email from X". Solve for X.

DMARC helps divide mail into two groups.

The first is mail that is sent by a single entity, under tight (typically corporate) control, primarily by machines rather than humans and likely in high volume. Primarily B2C or B2B, whether it be bulk or "transactional".

The second is mail that is sent by other entities, including almost all person-to-person email, as well as some subset of malicious / unwanted email.

X is "being sent by human beings".
