本文實例講述了C++實現郵件群發的方法。分享給大家供大家參考。具體如下：
關于生成隨機QQ郵箱不精確的問題，在之后版本打算另寫一個采集器插件進行帳號采集，所以，這個軟件只用來進行內容發送，郵箱進行隨機生成
如果你已經有采集來的QQ號，請復制到SendList.txt 替換內容即可
可以直接復制HTML代碼到郵件內容，保存即可。目前郵件內容最大設置為10000字節，如果有增大的必要，歡迎提交留言。
這是我學習后VC編程中涉及到多線程,socket,及一些WINDOWS API的宗合應用
使用說明：
一、SMTP設置
1、SMTP設置中，收件箱地址：填寫郵箱地址為帳號測試郵箱，可以填寫你自己的郵箱作為接收測試。打星號為必填。郵箱帳號及密碼，是即將用于群發的帳號和密碼
2、群發發送時間間隔，默認為零，可以選擇填寫發送間隔時間，單位為秒，防止多次快速發送相同內容被停用。
3、勾選郵件標題后插入系統時間，可以在標題上加上系統時間
4、導入群發列表，勾選后，可以點擊群發，暫停，繼續。（群發列表為程序目錄中SendList.txt)如果你有郵箱采集軟件，可以把彩集的郵箱地址按照格式，一行一個，放入其中），沒有的話，可以點擊“收件箱”頁面生成隨機QQ郵箱
二、郵件內容
1、填寫郵件標題，郵件內容可以為純文本，也可以是HTML代碼，附件目前只支持TXT文本。
2、群發前，請測試郵件內容，是否完整。附件是否正常接收。
三、收件箱
1、收件箱中順序生成QQ郵箱，請不要超過6位數QQ號，位數過大，生成時間過長，容易造成假死。
2、群發前，先生成QQ郵箱列表。如果你有采集郵箱帳號，可以按格式放入SendList.txt 中
版本更新說明：
1、可增加多個附件。
2、修復標題插入日期造成程序崩潰的BUG。
3、增加發送間隔時間選項。
4、支持HTML代碼
5、增加干預碼
