运行显示异常发送成功,但实际没有发送,不知为什么,环境为windows2003 server+Framework2.0



using System;
using System.Collections.Generic;
using System.Text;
using System.Net.Mail;
using System.Xml;
namespace xmas
{
class Program
{
static void Main(string[] args)
{

try
{

SmtpClient smtpClient = new SmtpClient();
MailMessage mailMessage = new MailMessage();
MailAddress fromMailAddress = new MailAddress("[e-mail]", "张三");
smtpClient.Host = "smtp.163.com";
smtpClient.EnableSsl = false;//true;
smtpClient.Port = 25;
smtpClient.UseDefaultCredentials = true;
smtpClient.Credentials = new System.Net.NetworkCredential("zhangsan", "password");
smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;
mailMessage.From = fromMailAddress;
mailMessage.To.Add("[e-mail]");
mailMessage.Subject = "test";
mailMessage.IsBodyHtml = true;
mailMessage.Body = "testbody";
smtpClient.Send(mailMessage);
mailMessage.To.Clear();
Console.WriteLine("Mail is sent to {0} sucessfully.", "zhangsan");
System.Threading.Thread.Sleep(600);

{
Console.WriteLine("{0}", ex.Message);
Console.ReadLine();
}

}

MailAddress from = new MailAddress("发送方地址");
MailAddress to = new MailAddress("接受方地址");
MailMessage mail = new MailMessage(from, to);
mail.Body = text;
mail.BodyEncoding = Encoding.UTF8;
mail.Subject = "主题";
mail.SubjectEncoding = Encoding.UTF8;
SmtpClient client = new SmtpClient("smtp.126.com");
client.UseDefaultCredentials = true;
NetworkCredential credential = new NetworkCredential("用户名", "密码");
client.Credentials = credential;

client.Send(mail);

To cja03:先谢谢你,但你的程序仍然不能发送! 运行显示无异常发送成功,但实际没有发送

换一个邮箱试试看呢.....

[funstar888]

换过，包括１６３，ＱＱ，sina的都试过了，都没错，就是收不到邮件！

不应该呀，你换这个代码试试

public struct MailItem
{
public string To;
public string From;
public string Subject;
public string body;
public string userName;
public string password;
public string smtpHost;
}

public class SendMail
{
public SendMail()
{
}
public void Send(MailItem aMailItem)
{
MailAddress from = new MailAddress(aMailItem.From);
MailAddress to = new MailAddress(aMailItem.To);
MailMessage message = new MailMessage(from, to);
message.Subject = aMailItem.Subject;
message.IsBodyHtml = true;
message.Body = aMailItem.body;
SmtpClient client = new SmtpClient(aMailItem.smtpHost);
//设置发送邮件身份验证方式
//注意如果发件人地址是[e-mail]，则用户名是abc而不是[e-mail]
client.Credentials = new NetworkCredential(aMailItem.userName, aMailItem.password);
client.Send(message);
}
}

163的应该是不行的，sina的年前用过可以。你看邮箱的边上给你写出 SMTP的都是允许用的，不写的一般都不让用！

[funstar888]

麻烦高人请出来指点！

///注意如果发件人地址是[e-mail]，则用户名是abc而不是[e-mail]
关键是这一句
企业邮箱，大多数都是abc
商业邮箱，大多数都是[e-mail]
