Chapter 9. I can't figure how to configure my website for sending E-mail

Any way I setup gmail, yahoo or hotmail accounts for this step. I'm stuck here.

Hi there,

Can you explain where / how you're stuck exactly? The book has detailed explanations of making this work for Gmail. Can you explain what you've done so far?

Cheers,

Imar

I just noticed, I have your Beginning ASP.NET 3.5 book.

Charpter 9, page- 309

1. I created a file called Email.aspx
2. Added the same exact code you specified to a Page_Load Handler, with the exception of my e-mail address and name.
3. In web.Config, I added the following code..

<system.net>
<mailSettings>
<smtp deliveryMethod="Network">
<network host="smtp.gmail.com" userName="my_ID" password="my password" port="465" />

</smtp>
</mailSettings>
</system.net>

I get a 'timeout' error when I run the Email.aspx page.

Hi there,

Take another look at step 4 on page 320 and at the Common Mistakes box at the bottom of the page. You left out the enableSsl attribute which Gmail requires. Also, try port 587 instead of 465. This works for me:

Code:

 
<system.net>
  <mailSettings>
    <smtp deliveryMethod="Network">
      <network host="smtp.gmail.com" userName="User" password="Password" port="587" enableSsl="true" />
    </smtp>
  </mailSettings>
</system.net>

Cheers,

Imar

Where do declare EnableSsl which you described in the above code?

PS. Page 320 in Beginning ASP.NET 3.5 is blank. Are you referring to a different book?

You have posted this in the forum for Beginning ASP.NET 4 so I assumed, silly me, you were using that book ;-)

You may want to take a look here: http://imar.spaanjaars.com/QuickDocId.aspx?QUICKDOC=505

In .NET 3.5, you manually need to create an SmtpClient and set the EnableSsl property to true as explained in that article. In .NET 4 you can do this declaratively in the web.config file.

Hi there,
for .Net 3.5 try this one

Code:

Dim mySmtpClient As New SmtpClient()
            Try
                mySmtpClient.EnableSsl = True
                mySmtpClient.Send(myMessage)
            Catch ex As Exception
                lblMessage.Text = "An Error Occurred, Please Try Again."
            End Try

The above code is in VB.NET
Hope this helps you.

Cheers,

Jack

Imar, I followed your link and added the following code to my website

Here's my code in Email.aspx

{public partial class Email : BasePage
{

protected void Page_Load(object sender, EventArgs e)
{
MailMessage myMessage = new MailMessage();
myMessage.Subject = "Test Message";
myMessage.Body = "Hello world, from PlanetWrox";

myMessage.From = new MailAddress("[email protected]", "My Name");
myMessage.To.Add(new MailAddress(""[email protected]", "My Name"));

SmtpClient mySmptClient = new SmtpClient();
mySmptClient.EnableSsl = true;
mySmptClient.Send(myMessage);
}
}
I added this code to web.config...

{
<system.net>
<mailSettings>
<smtp deliveryMethod="Network" from="[email protected]">
<network
port="587"
userName="[email protected]"
password="mypassword"
host="smtp.gmail.com"/>
</smtp>
</mailSettings>
</system.net>
}

I still get the following error...

System.Net.Mail.SmtpException: The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required.

Hi there,

That's strange. I just copied your code and configuration in a new web site and it works fine for me.

A few things you could check:

1. Is this really the code that is firing? Or does your page have other (Login) controls that try to send mail on their own?

2. Are your user name and password correct?

3. Are you using the right Gmail name? You need to use myname@gmail.com; not just myname.

4. Is your network allowing you to send mail and reach port 587?

Cheers,

Imar

Of the four possible solutions, I am only unsure about the last one. How do I check whether the network is allowing me to send mail and reach port 587?

PS. Great book so far. Is there another book that dives deeper into 'Displaying and Updating Data'?
