正在写邮件发送,为什么我收到邮件怎么这样啊
标题是:Delivery   Status   Notification   (Failure)
内容是:
This   is   an   automatically   generated   Delivery   Status   Notification.

Delivery   to   the   following   recipients   failed.
(邮箱名)
  信息碎片(0.29K)  
  邮件正文.eml(1.32K)

打开邮件正文,可以看到邮件的信息。
为什么出现这样的情况呢?

MailMessage   mailMsg   =   new   MailMessage();
mailMsg.BodyFormat   =   MailFormat.Html;
mailMsg.To   =   "wkidf@sina.com ";
mailMsg.From   =   "6325637@163.com ";
mailMsg.Subject   =   "标题 ";
mailMsg.Body   =   "内容 ";
             
mailMsg.Fields.Add( "http://schemas.microsoft.com/cdo/configuration/smtpauthenticate ",   "1 ");
mailMsg.Fields.Add( "http://schemas.microsoft.com/cdo/configuration/sendusername ",   "??? ");
mailMsg.Fields.Add( "http://schemas.microsoft.com/cdo/configuration/sendpassword ",   "??? ");
               
SmtpMail.SmtpServer.Insert(   0, "smtp.163.com ");
try
{

SmtpMail.Send(mailMsg);
this.Label1.Text= "成功 ";
return   false;
}
catch   (Exception   err)
{
this.Label1.Text=err.ToString();
return   true;
}  

还有就是不知道,就是我写问号的地方,是写哪个邮箱的帐号和密码啊???
如果成功应该在多长时间能接受到邮件啊?


------解决方案--------------------
发送人的帐号和密码

多长时间收到视SMTP服务器而定,一般像纯文本都是发了就有了~

垃圾邮件的原因有2个判断,一个是群发,一个是内容无实际内容或者有可被过滤到的内容

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Net.Mail;

public partial class Mail : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{

}
protected void Button1_Click(object sender, EventArgs e)
{

MailMessage myMail = new MailMessage( "收件人址 ", "发件人地址 ");

myMail.Subject = TextBox2.Text;
myMail.Body = TextBox3.Text;
myMail.IsBodyHtml = true;

SmtpClient client = new SmtpClient();
client.Host = "220.181.12.16 ";//SMTP服务器
client.Port = 25;

//验证你的用户名和密码
client.Credentials = new System.Net.NetworkCredential( "用户名 ", "密码 ");
client.Send(myMail);

}
}

发的不是很正规
