Carane nganggo Analisis header email
Apa sing dietung lan kapan nganggo
Maca header lengkap sawijining email lan nuduhake rute sing diliwati, wektu tundha ing saben server, lan asil SPF, DKIM lan DMARC. Uga menehi tandha spoofing, kayata domain pangirim sing beda karo alamat From. Kabeh ditindakake ing browser panjenengan.
Carane nganggo, langkah demi langkah
- Bukak header mentah email: ing Gmail pilih “Show original”, ing Outlook bukak properti pesen.
- Salin kabeh sing ana ing ndhuwur isi pesen lan tempel ing kothak.
- Waca asil autentikasi lan rute, hop paling lawas dhisik.
- Priksa peringatan kanggo domain sing ora cocog.
Tegese saben input
- Email headers – The complete header Blok, starting with baris such as Received: lan From:.
Carane maca asile
- Authentication – SPF, DKIM and DMARC results taken from the receiving server’s Authentication-Results header.
- Pesen Rincian – From, To, Tanggal, Message-ID, Return-Path, Reply-To lan mailer.
- Route – Saben siji server hop, its address lan the Wektu added ing antarane hops.
- Warnings – Domain mismatches lan failed checks.
Rumus
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.
Conto petungan
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.
Asumsi lan watesan
- 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.
- Ora ana yaiku uploaded.
Kesalahan umum
- Pasting only part the headers.
- Trusting the From name. It is easy to fake, so check the domain and authentication results.
- Treating a failed SPF as proof fraud. Forwarded mail often fails SPF.
