* 名稱：用Socket發(fā)送電子郵件
* 描述：本類實(shí)現(xiàn)了直接使用需要驗(yàn)證的SMTP服務(wù)器直接發(fā)送郵件，參考文章《用Socket發(fā)送電子郵件》作者：limodou
* 此文章比較早，他是用不用驗(yàn)證SMTP服務(wù)器發(fā)送郵件，現(xiàn)在基本上SMTP服務(wù)器都需要驗(yàn)證了，所以這個(gè)文章里的類
意義也不是很大！同時(shí)參考了[RFC 1869]和PHP手冊(cè)?。『蜕衔倪€有不同的是我用的不是fsockopen()函數(shù)
具體你自己看吧?。∥覄倓倻y(cè)試通過(guò)了，很爽！！
其實(shí)把這個(gè)類再改寫一下就可以直接發(fā)送帶附件的郵件了，期待。。。我過(guò)幾天給大家寫出來(lái)！
我剛剛調(diào)試通過(guò)，如果你不惡意去捉弄這個(gè)程序，他還是很聽話的，過(guò)些日子我會(huì)對(duì)他完善加上發(fā)送附件的功能??！

即使你的虛擬主機(jī)不支持MAIL函數(shù)，現(xiàn)在也不怕了！快快試試這個(gè)吧！

請(qǐng)尊重別人的勞動(dòng)成功，請(qǐng)保留此版權(quán)信息，謝謝！
