Menganalisa Email

Secara garis besar, email terdiri dari 2 bagian yaitu header dan body. Header berisi informasi tentang alamat pengirim dan alamat tujuan. Sedangkan body berisi isi dari surat. Berkas email dapat dilihat dengan menggunakan MUA (Mail User Agent) misalnya Mozilla Thunderbird. Berikut adalah berkas email beserta analisanya.

    Lalu bagemana saya tau email tadi udah dibaca ato belum (read/unread)

    • 4 August 2009 at 5:48 pm

      ya tinggal diinget-inget aja dah pernah dibaca apa belum..😀

      sebenernya saat email masuk ke MUA, email ketambahan header lagi tergantung dari MUA nya, karena aku make Mozilla Thunderbird, maka akan ketambahan header ini:

      From – Mon Aug 03 08:25:32 2009
      X-Account-Key: account2
      X-UIDL: GmailId122dddb59c7b8a32
      X-Mozilla-Status: 0001
      X-Mozilla-Status2: 10000000
      X-Mozilla-Keys:

      Nah, untuk mengetahui email dah dibaca, balasan berhasil terkirim, email forwarded, dll itu bisa dilihat di X-Mozilla-Status. X-Mozilla-Status bernilai 0001 jika email dah dibaca.

    trus kalo bedanya IMAP sama POP apa tu.
    Kalo di mail yahoo kan kita bisa set flag, bisa mark read/unread.
    gimana tu bos.
    Ohye, add di blogroll yow, skalian trackback link klo perlu..

    • 25 August 2009 at 8:53 am

      klo IMAP email disimpan di server, jadi klo pake komputer lain masih bisa ngecek email.. tapi klo POP email disimpan di komputer local trus yang di server dihapus, jadi klo ngecek dari komputer lain ga bisa.. klo ga salah sih gitu..
      aku belum bisa baca email header dari yahoo.. aku pake thunderbird ga bisa.. kata temenku kalo yahoo harus yang bayar baru bisa pake thunderbird, klo gratisan ga bisa.. tapi ga tau juga sih.. klo sampeyan tau, mohon dishare… wokeh???
