这篇文章主要介绍了C++实现邮件群发的方法,较为详细的分析了邮件发送的原理与C++相关实现技巧,非常具有实用价值,需要的朋友可以参考下
本文实例讲述了C++实现邮件群发的方法。分享给大家供大家参考。具体如下：
关于生成随机QQ邮箱不精确的问题，在之后版本打算另写一个采集器插件进行帐号采集，所以，这个软件只用来进行内容发送，邮箱进行随机生成
如果你已经有采集来的QQ号，请复制到SendList.txt 替换内容即可
可以直接复制HTML代码到邮件内容，保存即可。目前邮件内容最大设置为10000字节，如果有增大的必要，欢迎提交留言。
这是我学习后VC编程中涉及到多线程,socket,及一些WINDOWSAPI的宗合应用
使用说明：
一、SMTP设置
1、SMTP设置中，收件箱地址：填写邮箱地址为帐号测试邮箱，可以填写你自己的邮箱作为接收测试。打星号为必填。邮箱帐号及密码，是即将用于群发的帐号和密码
2、群发发送时间间隔，默认为零，可以选择填写发送间隔时间，单位为秒，防止多次快速发送相同内容被停用。
3、勾选邮件标题后插入系统时间，可以在标题上加上系统时间
4、导入群发列表，勾选后，可以点击群发，暂停，继续。（群发列表为程序目录中SendList.txt)如果你有邮箱采集软件，可以把彩集的邮箱地址按照格式，一行一个，放入其中），没有的话，可以点击“收件箱”页面生成随机QQ邮箱
二、邮件内容
1、填写邮件标题，邮件内容可以为纯文本，也可以是HTML代码，附件目前只支持TXT文本。
2、群发前，请测试邮件内容，是否完整。附件是否正常接收。
三、收件箱
1、收件箱中顺序生成QQ邮箱，请不要超过6位数QQ号，位数过大，生成时间过长，容易造成假死。
2、群发前，先生成QQ邮箱列表。如果你有采集邮箱帐号，可以按格式放入SendList.txt 中
版本更新说明：
1、可增加多个附件。
2、修复标题插入日期造成程序崩溃的BUG。
3、增加发送间隔时间选项。
4、支持HTML代码
5、增加干预码

/*******************************************************************
使用Socket的程序在使用Socket之前必须调用WSAStartup函数。
该函数的第一个参数指明程序请求使用的Socket版本，
其中高位字节指明副版本、低位字节指明主版本；
操作系统利用第二个参数返回请求的Socket的版本信息。
当一个应用程序调用WSAStartup函数时，操作系统根据请求的Socket版本来搜索相应的Socket库，
然后绑定找到的Socket库到该应用程序中。
以后应用程序就可以调用所请求的Socket库中的其它Socket函数了。
该函数执行成功后返回0。
