Email demo

Hi Imar hope you are well. I am having a problem sending email through the Email demo form. I have played about with it using many different settings â too many to mention. My code is as below and I have checked and got the smtp address of my mail server (as an IP address), a port number plus I was told that I will not need to pass in a login or password (even though I have tried it anyway).

The error I am getting is
Bad sequence of commands. The server response was: This mail server requires authentication when attempting to send to a non-local e-mail address. Please check your mail client settings or contact your administrator to verify that the domain or address is defined for this server.

My Code behind file.

Code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Net.Mail;

publicpartialclassDemos_Email : BasePage
{
protectedvoid Page_Load(object sender, EventArgs e)
    {
MailMessage myMessage = newMailMessage();
            myMessage.Subject = "Text Message";
            myMessage.Body = "Hello World, from Planet Wrox";
            myMessage.From = newMailAddress("******@.net", "MarkH");
            myMessage.To.Add(newMailAddress("******@.net", "This should be the receivers name"));
SmtpClient mySmtpClient = newSmtpClient();
            mySmtpClient.Send(myMessage);
    }
}

My web.config

Code:

 
<?xmlversion="1.0"?>

      <controls>
        <addtagPrefix="Wrox"tagName="Banner"src="~/Controls/Banner.ascx" />
      </controls>
    </pages>  
              <compilationdebug="true"targetFramework="4.0"/>
       </system.web>

  <!--my code for email-->
  <system.net>
  <mailSettings>    
    <smtpdeliveryMethod="Network"from = "MarkH &lt;******@.net&gt;">
      <networkhost= "**.*.**.***"port="25"/>
    </smtp>
  </mailSettings>
</system.net>
  <!--my code for email-->

  </configuration>

Many Thanks

Hi there,

Looks like you need to assign a user name and password, as explained on page 318.

Hope this helps,

Imar

Hi Imar and thanks for your prompt reply. Sorry I should have included that i uploaded my web site via the Visual Studio copy option. Hope this is fine or should I ftp it.

Regards
Mark

Hi Mark,

The way you deploy doesn't matter. Take a look at my initial reply: you need to assign a user name and password in web.config as explained on page 318.

Cheers,

Imar
