C#发送邮件收不到

xiongxyt1 2010-06-08 05:42:48

在http://win.51aspx.com/CV/GroupSendMail/
下在了一个，运行收不到邮件
我自己参照csdn写了一个最简单的
using System;
using System.Collections.Generic;
using System.Text;
using System.Net.Mail;

namespace 发送邮件
{
class Program
{
static void Main(string[] args)
{
string to = "297861197@qq.com";
string from = "xiongxyt2@163.com";
//string to = "jane@contoso.com";
//string from = "ben@contoso.com";
string subject = "Using the new SMTP client.";
string body = @"Using this new feature, you can send an e-mail message from an application very easily.";
MailMessage message = new MailMessage(from, to, subject, body);
SmtpClient client = new SmtpClient("smtp.163.com");
Console.WriteLine("Changing time out from {0} to 100.", client.Timeout);
client.Timeout = 100;
// Credentials are necessary if the server requires the client
// to authenticate before it will send e-mail on the client's behalf.
//client.Credentials = CredentialCache.DefaultNetworkCredentials;
try
{
client.Send(message);
}
catch (SmtpException se)
{
Console.WriteLine(se.Message);
}
}
}
}
输出超时，应该怎么办？
大家有C#编写的邮件既可以发送也可以收到的程序共享一下啊。

非常感谢啊，现在163是默认开启smtp/pop3的，不过你不说我不知道，用七楼的方法实现了。

建议使用 163邮箱试一试！





using System.Net.Mail;





public static bool SendMail(string messTo,string messBody)

        {

            MailMessage mess = new MailMessage();

            mess.From = new MailAddress("mmm306306@163.com", "报警系统");//发件人

            mess.Subject = "报警系统";//主题

            mess.IsBodyHtml = true;//允许HTML

            mess.BodyEncoding = System.Text.Encoding.UTF8;//编码

            mess.Body = messBody;

            SmtpClient client = new SmtpClient();//new 出 客服端的 smtp

            client.Host = "smtp.163.com";

            client.Credentials = new System.Net.NetworkCredential("mmm306306", "xxxxxxxxx");//需要发件人的账号 密码

            mess.To.Add(new MailAddress(messTo));//收件人 数组（可以群发）

            try

            {

                client.Send(mess);

                return true;

            }

            catch (Exception ex)

            {

                return false;

            }

        }

MailMessage mail = new MailMessage(); 

mail.To = "me@mycompany.com"; 

mail.From = "abc@126.com"; 

mail.Subject = "this is a test email."; 

mail.Body = "Some text goes here"; 

mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", "1"); //basic authentication



mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", "abc"); //set your username here



mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", "your password"); //set your password



here SmtpMail.SmtpServer = "smtp.126.com"; //your real server goes here 

SmtpMail.Send( mail );

使用其他邮箱看看
public void MailSend(string MailFrom,string MailTo,string MailPwd,string Mailtitle,string MailCon)
{
MailMessage MyMail = new MailMessage();
MyMail.From = new MailAddress("", "");
MyMail.To.Add(new MailAddress(""));
MyMail.Subject = Mailtitle;
MyMail.Body = MailCon;
MyMail.IsBodyHtml = false;
SmtpClient smtpclient = new SmtpClient();
smtpclient.DeliveryMethod = SmtpDeliveryMethod.Network;
smtpclient.Host = "";
smtpclient.Credentials = new System.Net.NetworkCredential(MailFrom, MailPwd);
smtpclient.Send(MyMail);
}

jmail.Message Jmail = new jmail.Message();
DateTime t = DateTime.Now;
String Subject = "";
String body = "";
String FromEmail = "";
String ToEmail = "";
Jmail.Charset = "GB2312";
Jmail.ContentType = "text/html";
Jmail.AddRecipient(ToEmail, "", "");
Jmail.From = FromEmail;
Jmail.MailServerUserName = "";
Jmail.MailServerPassWord = "";
Jmail.Subject = Subject;
Jmail.ContentType="text/html";
Jmail.Body = body + t.ToString();
Jmail.Send("", false);
Jmail.Close();

而且，你163的邮箱把smtp/pop3开启了么？好像新申请的邮箱都不给开了，老用户能开

好像给qq邮箱发有特殊限制吧。。。试试别的邮箱，应该就没问题的，只要smtp没写错
