Hello,

I am trying to create a "forgot password" section to my login section of my website. However, I do not know how to create and send emails with asp.net. Can someone please lead me in the right direction?

Thanks,

David

Dave,

You can use the system.web.mail class. You should set the Web.Mail.SmtpMail.SmtpServer property to localhost

There are many example on the Internet, i found a couple on google.

Check your from address and make sure it's valid.

Many mail server do not accept mail from invalid mail from address.

How come the following code is not working?

private void SubmitButton_Click(object sender, System.EventArgs e)
{
Server.ScriptTimeout = 1000;
Response.Flush();

SmtpMail.SmtpServer = "localhost";

MailMessage mail = new MailMessage();
mail.To = "myname@domain.com";
mail.From = this.EmailField.Text;
mail.Subject = this.SubjectList.SelectedItem.Text;
mail.Body = this.MessageField.Text;

try
{
SmtpMail.Send(mail);
}

catch(System.Exception ex)
{
ResponseLabel.Text = ex.Message;
}
Response.Flush();
}

For some reason, the mail is not being sent to
myname@domain.com.

I tried changing 'SmtpMail.SmtpServer = "localhost"', to the following:

1. SmtpMail.SmtpServer = "mail.finsoftware.com";
2. //SmtpMail.SmtpServer = "mail.finsoftware.com"; (commented out)

and yet it's still not being sent and there are no exceptions being catched.

Anyone help would be highly appreciated.

Thanks

From the rejected mail, it's obvious that you are trying to send to a invalid address. It'll work find once you put in the write address

From: <mail.From@domain.com>
To: <mail.To@domain.com>

Nope, I replaced that part manually before I posted it here, coz I don't wanna list down my real e-mail addy to avoid spam. I'm sure it's a valid e-mail address (that's why I was able to receive the failure notice).

Bruce,

I tried to replace the FROM field to a string constant
(i.e. mail.From = "myname@domain.com") but still no results..
No exceptions being catched.

Any other ideas?

Hmmmm.....

I am not sure what's happening. If the SMTPMail.send is not giving you any error. That means the mail is somewhere in the mail server. The only reason the mail is not delivering in this case is that the from & to address are invalid. I do not think it is related to your code.

What I would do is to try change the send to address to some hotmail or yahoo address and see if it work.

Bruce, it finally worked when I used my AOL and YAHOO e-mail in
either FROM and TO fields. For some reason, it's not working
for my company e-mail! I'm quite sure it's a valid e-mail addy
because, obviously it's the one I use for work. I remember it worked at least once, for some reason it stopped working.
