<?xml version="1.0"?>
<configuration>
	<system.web>
    <pages theme="DarkGrey">
      <controls>
        <add tagPrefix="Wrox" tagName="Banner" src="~/Controls/Banner.ascx" />
      </controls>
    </pages>
		<compilation debug="true" targetFramework="4.0"/>
	</system.web>
    <system.net>
      <mailSettings>
        <smtp deliveryMethod="Network"
                 from="arman &lt;[email protected]&gt;">
          <network host="smtp.yahoo.com" />
        </smtp>
      </mailSettings>
    </system.net>
</configuration>

code behind of email page

Code:

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

public partial class site_Demos_Email : BasePage
{
    protected void Page_Load(object sender, EventArgs e)
  {
    MailMessage myMessage = new MailMessage();
    myMessage.Subject = "Test Message";
    myMessage.Body = "Hello world, from Planet Wrox";
    myMessage.From = new MailAddress("[email protected]", "arman");
    myMessage.To.Add(new MailAddress("[email protected]", "asjad"));

    SmtpClient mySmtpClient = new SmtpClient();
    mySmtpClient.Send(myMessage);
    }
}

You need to specify a user name and password as shown in the book. Also, Yahoo may require a portnumber as well; see the book for examples.

sir now i specified the username and password. But i don't know how to specify the port number. You have told us possible range of the port number in the book. But how can we determine the exact port number?
Please guide

Hi,

If you have a look at http://answers.yahoo.com/question/in...4165102AAAVBA1 it looks like the smtp port number for Yahoo is 465 using SSL.

Therefore your web .config file should like something like:-

<network enableSsl="true" userName="your_user_name" password="your_password" host="smtp.mail.yahoo.com" port="465"/>

Hope this helps.

Cheers,

Ian

sir here is my web.config file code

Code:

<?xml version="1.0"?>
<configuration>
	<system.web>
    <pages theme="DarkGrey">
      <controls>
        <add tagPrefix="Wrox" tagName="Banner" src="~/Controls/Banner.ascx" />
      </controls>
    </pages>
		<compilation debug="true" targetFramework="4.0"/>
	</system.web>
    <system.net>
      <mailSettings>
        <smtp deliveryMethod="Network"
                 from="arman &lt;[email protected]&gt;">
          <network enableSsl="true" userName="arman" password="my_password" host="smtp.mail.yahoo.com" port="465"/>
        </smtp>
      </mailSettings>
    </system.net>
</configuration>

and here is email.aspx.cs code

Code:

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

public partial class site_Demos_Email : BasePage
{
    protected void Page_Load(object sender, EventArgs e)
  {
    MailMessage myMessage = new MailMessage();
    myMessage.Subject = "Test Message";
    myMessage.Body = "Hello world, from Planet Wrox";
    myMessage.From = new MailAddress("[email protected]", "arman");
    myMessage.To.Add(new MailAddress("[email protected]", "arman"));

    SmtpClient mySmtpClient = new SmtpClient();
    mySmtpClient.Send(myMessage);
    }
}

Now i have implemented all the code according to your instruction. But it still does not work. i have bolded the line which shows error.
Now what may be the problem at this line?

What's the erorr you are getting?

Also, are you sure your user name is correct? Have you tried passing in your full account name, with and without the @yahoo.com part?

Otherwise, try Google for

SmtpClient Yahoo web.config

and you'll find various examples of config code that worked. I don't use Yahoo, so I am not 100% sure what you need to configure.

Cheers,
