发送邮件报错说明

发送邮件如果发送人的邮箱用户名与邮箱密码都没有填写错误：如果报：参数或变量中有语法错误。服务器响应为:mail from address must be same as authorization user错误，问题可能出在authorization user 没授权。如果是QQ邮箱，那么只要进入QQ邮箱，QQ邮箱：设置---账户找到POP3/IMAP/SMTP服务都开启。这时候发现可以发送邮件了。

如果报：SMTP 服务器要求安全连接或客户端未通过身份验证。服务器响应为:Must issue a STARTTLS command first. 可能出现的问题是发送邮件的服务器端口（smtp.Port）配置错误。例如：smtp.Port = 25

如果报：命令顺序不正确。服务器响应为:Error: need EHLO and AUTH first ! 很有可能是发件人邮箱的用户名写错了；例如：（smtp.Credentials = new NetworkCredential("邮箱的用户名", "发件人邮箱密码");

如果报：参数或变量中有语法错误。服务器响应为:mail from address must be same as authorization user 很有可能是发件人邮箱的密码错误了：例如：（smtp.Credentials = new NetworkCredential("邮箱的用户名", "发件人邮箱密码");
