Susahnya Atasi Spam

Spam adalah email yang tidak kehendaki dan datangnya berulang. Namun sayangnya, polanya berubah-ubah, sehingga mem-blokirnya jadi rada susah. Subject, From, bisa berbeda-beda dari waktu ke waktu. Bahkan isinya atau body juga berbeda. Tapi perasaan mengatakan jika itu sebenernya spam. Contoh spam yang beda-beda namun esensinya sama, yaitu :

Subject:     Service alert (important)
From:     "Cimbclicks"
Date:     Fri, September 12, 2014 8:22 am
To:     Undisclosed recipients:;

Subject:     Restore your access

Adalagi contoh dengan pola serupa dengan mengatasnamakan Sistem Administrator :
