SPF lookups 7/10

SPF / DKIM / DMARC above reflect the last 3 emails we've observed. DMARC policy is read live from DNS.

Authentication

DMARC reports sent to vali.email. Policy p=reject means receivers actively block or quarantine spoofed mail.

SPF alignment: all 18 observed emails use a return-path aligned with qonto.com (em7046.qonto.com, cio35236.qonto.com). SPF authenticates the visible From — supports DMARC directly.

DKIM alignment: all 17 observed emails sign with a domain aligned with qonto.com (qonto.com, cio35236.qonto.com). DKIM authenticates the visible From — supports DMARC directly.

Other SPF authorizations

ESPs this brand has authorized in their SPF record. We confirm them with a green ✓ only after seeing recurring use (3+ emails across 2+ days). Until then they stay here — either we haven't observed any email yet, or we've seen a handful but not enough to call them a regular sender for the brand.
