SPF lookups 4/10

SPF / DKIM / DMARC above reflect the last 4 emails we've observed. DMARC policy is read live from DNS.

Authentication

DMARC reports sent to onsecureserver.net. Policy p=quarantine means receivers actively block or quarantine spoofed mail.

SPF alignment: all 4 observed emails use a return-path aligned with landbankuniversity.biz (support.landbankuniversity.biz). SPF authenticates the visible From — supports DMARC directly.

DKIM alignment: all 4 observed emails sign with a domain aligned with landbankuniversity.biz (support.landbankuniversity.biz). 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.
