0、有关TLS和SSL
SSL/TLS是用来加密邮件流的。
假设不加密的话非常easy被人破解。
只是既然是要发送广告邮件，这个就不用在意了，使用没加密的即可。
另外在使用的时候，发现，qq的邮箱须要使用SSL才干连接上，这个再以后须要用qq发群邮件的时候再来处理。这里临时仅仅是使用163的邮箱，作为发送端

} 2、測试使用以及效果
申请了一个測试邮箱(任意申请的)
password是：123456789z
那么给自己发送邮箱(含有附件的測试project例如以下)
// ConsoleApplication1.cpp : 定义控制台应用程序的入口点。
//
#include "stdafx.h"
#include "iostream"
using namespace std;
#include "SendMail.h"
void TestSendMail()
{
for (int index = 0; index < 10; index++)
{
CSendMail mail;
sMailInfo info;
// memcpy(info.m_pcIPAddr, "123.125.50.138", strlen("123.125.50.138"));
info.mail_server_name = "smtp.163.com";
info.mailbox_receiver = "[email protected]";
info.mailbox_sender = "[email protected]";
info.mailbox_user_name = "qq2590995733";
info.mailbox_user_pwd = "123456789z";
info.mailbox_sender_show_name = "taobao客服";
info.mail_title = "游戏激活key";
info.mail_body = "XX，你妈妈喊你回家吃饭了！！！
"; mail.AddFilePath("c:\\Download History.log"); mail.AddFilePath("c:\\1.jpg"); mail.AddFilePath("c:\\3.log"); mail.BeginSendMail(info); } } int _tmain(int argc, _TCHAR* argv[]) { TestSendMail(); return 0; }
效果例如以下：
3、补充
代码是參考csdn一个project的，原来是依赖于mfc的，给修正了一下，只是还是须要增加atl(做base64的编码)。还得多多感谢原作者！
事实上这里还是存在有问题的，比方发送出去的附件，在下载的时候，是有那么一点点被改变了。
只是这里主要是想要表达怎样发送邮件，所以。。应该会在后面进行修复吧。
