只鎖ip效果有限吧~應該是針對mail做全面的分析才對,
ip很好偽裝,要封先把大陸的ip都封了,
應該就可以減少很多垃圾郵件....
一些ISP機房給的IP有時也被當黑名單
小弟就有買過一家ISP的主機代管
租用機櫃要做 Mail Server
一上線才發現這IP已經當黑名單
真是不知該說什麼.....
最後當然是再換IP
搞很久才上線,嗚嗚
這樣會作到瘋ㄟ...
由antispam發展的歷史包袱可知,
所有的Spammer 都知道 - 『查來源』(黑白名單,RBL ,safelist),『濾內容法』(關鍵字庫,內容過濾:貝式分析,rule base,啟發式分析) 是目前傳統對抗spam的主要方法
但這些方法就現行的spam的技術,卻都已無法有效防止
Why ?
現在的spammer因背後涉及龐大的商業利益,背後都有產業撐腰,也有高深的Messaging IT技術,
最新的攻擊手法都使用Spam Botnet(殭屍電腦網路)攻擊法 (或Botnet+附檔型SPAM)
『Botnet方式的spam方式『造假, 位置一直變,內容一直變』正是破解傳統antispam的新技倆 !! 』
其具有三個重要特徵,『信件一定造假』,『發送位址一直變(IP輪變)』,『內容一再改變(content twist)』 !!!
新的spammer BOTnet發送spam手法,有效地破解傳統以『查來源』(黑白名單,RBL ,safelist),『濾內容法』(關鍵字庫,內容過濾:貝式分析,rule base,啟發式分析)發法為主的antisapm
故傳統的內容過濾式為大宗的antispam solution,在阻擋上容易發生抓襟見軸的窘境,為了擋一變再變的spam,不斷train樣本(有效嗎?)不斷加rule(誤判越來越高,效能越來越低)
但問題始終越來越嚴重....
故解決垃圾郵件新思維應跳開傳統以『查來源』『濾內容法』的思考模式,要針對如何防範 『spam mamil 會一直造假, 位置一直變,內容一直變』的特性去尋求解決之道
