在asp.net中发送邮件失败 [英] Failure sending mail in asp.net

问题描述

大家好



这里我面临发送邮件的问题，当我使用这个脚本的gmail，工作正常，但当我尝试我的邮件服务器显示错误但在我的邮件服务器工作正常，直接发送





这里我的脚本

 使用（MailMessage mm =  new  MailMessage（txtemail.Text ，  [e-mail]））
 {
 mm.Subject =  来自网站的消息名称： + txtname.Text; 
 mm.Body =   NAME： + txtname.Text +   \ n +  地址： + txtaddr.Text +   \ n +  电话： + txtphone.Text +   \ n +   E-mailID：  + txtemail.Text +   \ n +  注意： + txtnote.Text +   \\\
; 
 mm.IsBodyHtml =  false ; 
 SmtpClient smtp =  new  SmtpClient（）; 
 smtp.Host =   mail.myserver.com; 
 smtp.EnableSsl =  false ; 
 NetworkCredential NetworkCred =  new  NetworkCredential（  mailme @ myserver.com，  pwd）; 
 smtp.UseDefaultCredentials =  true ; 
 smtp.Credentials = NetworkCred; 
 smtp.Port =  26 ; 
 smtp.Send（mm）; 
 ClientScript.RegisterStartupScript（GetType（），  alert，  alert（'电子邮件已成功发送'）;， true ）; 
 txtname.Text =  ; txtaddr.Text =  ; txtemail.Text =  ; txtnote.Text =  ; txtphone.Text =  ; 
} 

显示发送邮件失败等错误。



如何解决这个问题



谢谢..

解决方案

您可以使用下面给出的示例代码。它是一个工作的。

 使用 System.Net.Mail; 
 
  string  MailSrvr =   yourserver.com; 
 SmtpClient mclient =  new  SmtpClient（）; 
 MailMessage mailmsg =  new  MailMessage（）; 
 mclient.Host = MailSrvr; 
 MailAddress frmadd，toadd，tocc，tobcc; 
 
 frmadd =  new  MailAddress（  fromaddress， 来自发件人名称）; 
 mailmsg.From = frmadd; 
 mailmsg.IsBodyHtml =  true ; 
 mailmsg.Priority = MailPriority.Normal; 
 mailmsg.Subject =  测试主题; 
 
 strline =  邮件正文; 
 mailmsg.Body = strline; 
 
 toadd =  new  MailAddress（  toaddress，  To Receiver Name）; 
 mailmsg.To.Add（toadd）; 
 
 tocc =  new  MailAddress（  ccaddress，  CC）; 
 mailmsg.CC.Add（tocc）; 
 
 tobcc =  new  MailAddress（  bccaddress，  BCC）; 
 mailmsg.Bcc.Add（tobcc）; 
 
 mclient.Send（mailmsg）; 
 mailmsg.Dispose（）;

下面是我用于发送电子邮件的代码我相信它会起作用



下面是你需要使用的库文件为此目的

System.Net.Mail;



，然后转到配置中的web.config中的代码部分

定义主机，即您要从中发送消息。

每个站点都有端口号我以gmail为例，它的端口号是587

 <   system.net  >  
 <   mailSettings  >  
 <   smtp    < span class =code-attribute> from   =  emailid >  
 <   network     host   =  [e-mail]    port   =  587    userName   = 用户名   密码  = 密码    /  >  
 <   / smtp  >  
 <   / mailSettings  < span class =code-keyword>>  
 <   / system.net  >  

以下是s的实际代码最终邮件

 string toemail =email address; 
 string message =这是一封示例电子邮件; 
 MailMessage mail = new MailMessage（）; 
 mail.To.Add（toemail）; 
 mail.Subject =邮件样本; 
 mail.Body = message; 
 mail.IsBodyHtml = false; 
 SmtpClient smtp = new SmtpClient（）; 
 smtp.EnableSsl = true; 
 smtp.Send（mail）; 

Hi Prasanna，



你的ISP阻止端口25？您是否尝试使用端口587？或者，请参阅这篇文章 http ：//dotnet4hosting.asphostportal.com/post/ASPNET-4-Hosting-ASPHostPortal-How-to-Send-Email-with-Gmail-SMTP.aspx [ ^ ]。

解决方案

Hi,

You can use the sample code given below. Its a working one.

using System.Net.Mail;

    string MailSrvr = "yourserver.com";    
    SmtpClient mclient = new SmtpClient();
    MailMessage mailmsg = new MailMessage();
    mclient.Host = MailSrvr;
    MailAddress frmadd, toadd, tocc, tobcc;

    frmadd = new MailAddress("fromaddress", "From Sender Name");
    mailmsg.From = frmadd;
    mailmsg.IsBodyHtml = true;
    mailmsg.Priority = MailPriority.Normal;
    mailmsg.Subject = "Test Subject";

    strline = "body of the mail";
    mailmsg.Body = strline;

    toadd = new MailAddress("toaddress", "To Receiver Name");
    mailmsg.To.Add(toadd);

    tocc = new MailAddress("ccaddress", "CC");
    mailmsg.CC.Add(tocc);    

    tobcc = new MailAddress("bccaddress", "BCC");
    mailmsg.Bcc.Add(tobcc );    

    mclient.Send(mailmsg); 
    mailmsg.Dispose();

below is the code I have used for emailing purpose I'am sure it will work

Below is the library file you need to use for this purpose
System.Net.Mail;

before going to code in web.config under configuration section
define host i.e. from which you want to send the message.
every site will have port number i have taken gmail as an example its port number is 587

<system.net>
    <mailSettings>
      <smtp from="emailid">
        <network host="[e-mail]" port="587" userName="username" password="password" />
      </smtp>
    </mailSettings>
  </system.net>

below is the actual code to send mail

string toemail = "email address";
        string message = "Hi this is a sample email";
        MailMessage mail = new MailMessage();
        mail.To.Add(toemail);
        mail.Subject = "Sample mail";
        mail.Body = message;
        mail.IsBodyHtml = false;
        SmtpClient smtp = new SmtpClient();
        smtp.EnableSsl = true;
        smtp.Send(mail);

Hi Prasanna,

Does your ISP block port 25? Have you try to use port 587? Or, please refer to this post http://dotnet4hosting.asphostportal.com/post/ASPNET-4-Hosting-ASPHostPortal-How-to-Send-Email-with-Gmail-SMTP.aspx[^].
