请帮助.....

解决方案

请更改代码并检查...

 MailAddress mailFrom =  new  MailAddress（GetAppSettingValue（Constants.K_APP_KEY_MAIL_FROM））; 
 MailAddress mailTo =  new  MailAddress（mailToAdd）; 
 
 使用（MailMessage message =  new  MailMessage（mailFrom，mailTo））
 {
 message.Priority = MailPriority.Normal; 
 message.Subject =   mailSubj; 
 message.Body =   mailBody; 
 
  //  其他用户列表不为空，请将其包含在收件人列表中。 
  if （！additionalToAdd.IsNull（））
 {
 message.To.Add（ new  MailAddress（additionalToAdd））; 
} 
 
 SmtpClient client =  new  SmtpClient（）; 
 client.Send（message）; 
} 
 

在网络配置中添加以下内容

 <   system.net  >  
 <   mailsettings  >  
 <   network     enablessl   =  true    host   =  smtp.gmail.com    port   =  587   用户名  =  [e-mail]   密码  = 密码    /  >  
 <   smtp    来自  = 密码    deliverymethod   =  SpecifiedPickupDirectory >  
 <   specifiedpickupdirectory     pickupdirectorylocation   =  D：\00TestEmails \    /  >  
 <   / smtp  >  
 <   / mailsettings  >  
 <   / system.net  >  

使用上述任何一种网络或smtp。

第一个用于发送邮件..而第二个用于将邮件存储在指定的目录位置。



希望它会对你有帮助。

引用：

smtp.Host =[e-mail];

有你的问题 - 你正在把一个电子邮件地址放到一个属性中，该地址需要发送你电子邮件的计算机的IP地址或名称。

SmtpClient.Host属性 [ ^ ]：

获取或设置主机的名称或IP地址用于SMTP事务。

将主机设置为有效的SMTP服务器。

你可以试试这个。 ..

 ///< summary> 
 ///发送邮件给管理员。 
 ///< / summary> 
 ///< param name =mailText>要发送的消息< / param> 
 ///< returns>如果邮件发送失败，则发送邮件为真。< / returns> 
 private Boolean SendMail（String mailText）
 {
 Boolean sendMailResult; 
 try 
 {
 SmtpClient smtpServer = new SmtpClient（）; 
 smtpServer.Credentials = new System.Net.NetworkCredential（mailFromId，mailFromPassword）; //在此处添加电子邮件ID和密码。 
 smtpServer.Port = 587; 
 smtpServer.Host =mail.hostname.com; 
 smtpServer.EnableSsl = true; //不要将其用作绕过AntiVirus / Firewall的异常。 
 // smtpServer.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network; 
 MailMessage alertMail = new MailMessage（）; 
 alertMail.From = new MailAddress（mailFromId）; //添加邮件。 
 alertMail.Subject =申请日报状态; 
 String mailId =; // recepients emailid 
 alertMail.To.Add（mailId）; 
 alertMail.Body = mailText; 
 alertMail.IsBodyHtml = true; 
 System.Net.ServicePointManager.ServerCertificateValidationCallback + = 
 delegate（object sender，System.Security.Cryptography.X509Certificates.X509Certificate certificate，
 System.Security.Cryptography.X509Certificates.X509Chain chain，
 System.Net.Security.SslPolicyErrors sslPolicyErrors）
 {
 return true; // ****始终接受
}; 
 smtpServer.Send（alertMail）; 
 sendMailResult = true; 
 alertMail.Dispose（）; 
 smtpServer.Dispose（）; 
返回sendMailResult; 
} 
 catch（exception ex）
 {
 string mailSendingFailMessage =邮件发送失败。; 
 mailSendingFailMessage + = ex.GetType（）。ToString（）++ ex.Message; 
 Logger.AppendMessageToStringBuilder（mailSendingFailMessage，2）; 
 sendMailResult = false; 
返回sendMailResult; 
} 
最后
 {
 
} 
}

please help .....

解决方案

Please change the code and check...

MailAddress mailFrom = new MailAddress(GetAppSettingValue(Constants.K_APP_KEY_MAIL_FROM));
               MailAddress mailTo = new MailAddress(mailToAdd);

               using (MailMessage message = new MailMessage(mailFrom, mailTo))
               {
                   message.Priority = MailPriority.Normal;
                   message.Subject = "mailSubj";
                   message.Body = "mailBody";

                   // Additional user list is not empty, include them in 'To' list.
                   if (!additionalToAdd.IsNull())
                   {
                       message.To.Add(new MailAddress(additionalToAdd));
                   }

                   SmtpClient client = new SmtpClient();
                   client.Send(message);
               }

In web config add the following

<system.net>
      <mailsettings>
          <network enablessl="true" host="smtp.gmail.com" port="587" username="[e-mail]" password="password" />
          <smtp from="password" deliverymethod="SpecifiedPickupDirectory">
            <specifiedpickupdirectory pickupdirectorylocation="D:\00TestEmails\" />
          </smtp>
      </mailsettings>  
    </system.net>

Use any of the above line either network or smtp.
The first one is used to send mail..while the 2nd is used to stored the mail in the specified directory place.

Hope it will help you.

Quote:

smtp.Host = "[e-mail]";

There's your problem - you're putting an email address into a property which expects either the IP address or name of the computer which will send your email.

SmtpClient.Host Property[^]:

Gets or sets the name or IP address of the host used for SMTP transactions.

Set the host to a valid SMTP server.

you can try this ...

/// <summary>
        /// Send mail to admins.
        /// </summary>
        /// <param name="mailText">Message to be send</param>
        /// <returns>True if mail sent otherwise false if mail sending failed.</returns>
        private Boolean SendMail(String mailText)
        {
            Boolean sendMailResult;
            try
            {
                SmtpClient smtpServer = new SmtpClient();
                smtpServer.Credentials = new System.Net.NetworkCredential(mailFromId, mailFromPassword); //Add Email-Id and Password here.
                smtpServer.Port = 587;
                smtpServer.Host = "mail.hostname.com";
                smtpServer.EnableSsl = true; //Do not use this as to bypass exception from AntiVirus/Firewall.
                // smtpServer.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
                MailMessage alertMail = new MailMessage();
                alertMail.From = new MailAddress(mailFromId); //Add Mail From.

 		alertMail.To.Add(mailId);
                alertMail.Body = mailText;
                alertMail.IsBodyHtml = true;
                System.Net.ServicePointManager.ServerCertificateValidationCallback +=
               delegate(object sender, System.Security.Cryptography.X509Certificates.X509Certificate certificate,

            }
            catch (Exception ex)
            {
                string mailSendingFailMessage = "Mail sending failed.";
                mailSendingFailMessage += ex.GetType().ToString() + " " + ex.Message;
                Logger.AppendMessageToStringBuilder(mailSendingFailMessage, 2);

                return sendMailResult;
            }
            finally
            {
