Authentication

DMARC published as p=none with no rua= reporting — monitor-only, and the sender isn't collecting reports either.

SPF alignment: all 2 observed emails use a return-path aligned with adriaan-dekker.nl (em-3694523.adriaan-dekker.nl). SPF authenticates the visible From — supports DMARC directly.

Placement by ESP

Which ESP's emails are landing where. Sorted by spam % so problem senders surface first.
