mfc 发送邮件外加附件

本文主要是关于如何在mfc中如何发送邮件外加附件的~
首先要对smtp和mime这两部分有一定的了解，smtp是全称是简单的邮件传输协议，而协议是认为规定的规则，有一定的格式要求，一点错误都不可以。我在这儿犯错了，调试了好久。
  smtp：规定示例如下（已经跟服务器连接上了）
"EHLO hello\r\n"\\hello 是一个字符串随便啥都可以，就向服务器发送问好信号
"AUTH LOGIN\r\n"        \\向服务器说我要登录了
"账号\r\n" \\账号密码都要经过base64编码，输入完账号密码之后如果成功的的话， \\服务器会返回编号235
"密码\r\n"
"MAIL FROM: <str>\r\n"   \\从哪个邮箱发送的，str指的是你自己此时登录的邮箱
"RCPT TO:<str>\r\n"\\给谁发送的，str指的是目标邮箱，你是向谁发送的
"DATA\r\n" \\跟服务器说你准备要发送内容了
"From:sendername<SendFrom>\r\n"\\sendername顾名思义就是发送者的姓名（可以随便写）
"To: str\r\n"            \\给谁发送的，str指的是目标邮箱，你是向谁发送的，如果没有发送 \\这一条的话，会出现发送密信
"Subject:Str\r\n" \\str：发送的主题
"Content-type:text/html;Charset=gb2312\r\n" \\说你是按照html格式发送的
"Content-Transfer-Encoding:8bit\r\n\r\n"   \\你传送的格式，是8位的
"Content\r\n\r\n"\\Content你的发送内容
"\r\n.\r\n" \\发送结束的标志
