So, #Microsoft and #Google are the businesses that today, are defining rules for how #emails work: #DKIM, #DMARC, #SPF

On the paper, everything sounds fine.

In practice? They are the first to fail controls.

- Google keeps failing SPF controls
- Microsoft does not validate correctly DKIM records

This is, again, mob behaviour. We need more diversity in email service providers.

Not to mention how too many businesses are currently being hostages of the above, locked in their clouds.
