Penjelasan dari Email Header diatas adalah sebagai berikut :
Dari informasi diatas score Email adalah 7.8, dan jika score SPAM Assassin nya adalah 5.0 maka secara otomatis Email tersebut termasuk kategori SPAM. Dan jika Spam Auto Delete Aktif / Enabled dengan score 7 maka Email tersebut akan secara otomatis dihapus. Tetapi jika Spam Auto Delete Aktif / Enabled dengan score 8 maka email tersebut hanya ditandai sebagai ***SPAM*** dan tidak secara otomatis terhapus dari sistem.
Beberapa hal yang menentukan sebuah nilai atau score dari email :
o Baris subjek adalah huruf kapital semua
o Subjek atau Judul Email mengandung : As Seen, Free, For Only, Your Bills, Your Own, Your Familly
o Besarnya HTML Font size
