Yadda ake karanta sakamako
- Authentication – SPF, DKIM and DMARC results taken from the receiving server’s Authentication-Results header.

- Route – Kowanne server hop, its address da the Lokaci added tsakanin hops.
- Warnings – Domain mismatches da failed checks.
Dabarar lissafi
Received headers are added at the top by each server, so they are read bottom to top. The delay at a hop is its timestamp minus the previous hop’s. Total delivery time is the last timestamp minus the first.
Misali da aka warware
A message with spf=pass, dkim=pass and dmarc=pass sent from the same domain as its From address, delivered in 5 seconds across 2 hops, shows no warnings.
Zato da iyakoki
- The receiving server’s Authentication-Results header is trusted. Earlier Received lines can be forged by a sender.
- Time stamps use each server’s own clock, so small negative delays can appear.
- Babu komai shi ne uploaded.
Kurakuran da aka saba yi
- Pasting only part na the headers.
- Trusting the From name. It is easy to fake, so check the domain and authentication results.
- Treating a failed SPF as proof na fraud. Forwarded mail often fails SPF.
