垃圾郵件過濾軟體之市場價位與功能需求分析

拜通信資訊科技蓬勃發展之賜，網際網路頻寬與速度相繼突破，行銷業者順應潮流，結合網路科技，網路行銷儼然已成為業界最現代化的佼佼者；在網路行銷興起的年代，業者除了靜態的架設網站提高曝光率外，就是動態的不斷發送電子廣告文宣，以打動消費者心弦，利用電子郵件作廣告行銷便是其中重要的一環，然而，這種未經收信者同意即強行搶灘的電子廣告信函，不但數量急速增加、浪費網路頻寬、潛藏資安危機、提高管理成本、降低生產力與工作效率，成為人見人惡的「垃圾郵件」(spam)。迄今，垃圾郵件的濫發可謂已到達相當猖獗的地步，郵件使用人多引領厚望政府立法規範與民間業者提供防堵軟體過濾；對於前者，目前送審的二件法案均已完成草擬，但尚未完成立法；而後者，學術界對垃圾郵件過濾軟體的討論計十四篇，皆着墨於如何探勘、偵測、篩選等技術面的探討，而其市場面卻乏人問津。由於垃圾郵件與反垃圾郵件的戰爭早已悄悄展開，雙方均使出渾身解數，進行著不流血的攻防戰，進攻者瘋狂濫發，防守者極力防堵、過濾軟體應運而生，因而市面上已出現二十種以上的過濾軟體，本研究即以這些軟體的市場面，探討郵件使用者的接收數量與軟體需求、及不同過濾功能與過濾軟體需求之關係，以對垃圾郵件過濾軟體提供者及一般郵件使用者提出管理垃圾郵件實務上的建議，並對所有網路族有所助益。
