Follow the steps
1. Select the site or Virtual Directory in IIS
2. In Feature View, Right side you see SMTP mail
3. if exists, Click to open a dialogbox
4. Goto Radio button "Store e-mail in pickup directory" enter a valid directory path,
5. Your SMTP starts working, it will not send mails, but all outgoing mail formats you can see, this would be great while debugging, insteading of choking your mail server.

Hope it helps,

I think, you need to check your proxy settings in "internet options". If you are using proxy/'hide ip' applications, this problem may be occurs.

You've specified the host in your web.config as your local machine: 127.0.0.1 is the loopback address.

If you don't want to set up an SMTP server on your web server, you'll need the configuration of a public one. A quick google suggests Yahoo uses:

host="smtp.mail.yahoo.com"
port="465"

Try putting that in your web.config and let us know how you get on.

Yahoo may also require SSL and I don't see a way to specify that here:

There is EnableSsl property on the SmtpClient class. So in other words, to send mail via Gmail you can use:

var client = new SmtpClient
{
Port = 587,
EnableSsl = true,
DeliveryMethod = SmtpDeliveryMethod.Network,
UseDefaultCredentials = false,
Credentials = new NetworkCredential("yourGmailUsername", "yourGmailPassword"),
Host = "smtp.gmail.com"
};
var message = new MailMessage
{
// Setup your MailMessage instance here...
}
client.Send(message);

// Send Regisration number to user's mail box after submitting the form successfully
SmtpClient smtpc = new SmtpClient("smtp.gmail.com");
smtpc.Port =587;
smtpc.EnableSsl = true;
smtpc.UseDefaultCredentials = false;
string user = "sirikondaswapna@gmail.com"; //<--Enter your gmail id here
string pass = "swapnashankar19";//<--Enter Your gmail password here
string sub = "Form filling Application:"; //Subject for your website
string msg = "Webcome to http://msdotnet.co.in Your Registration Number is: " + Label2.Text; //Message body
smtpc.Credentials = new NetworkCredential(user, pass);
MailMessage email = new MailMessage(user, TextBox6.Text, sub, msg);
email.IsBodyHtml = true;
smtpc.Send(email);

Label1.Text = "Your form has been submitted successfully.Take Preview Now,Your Registration Number is: ";
Label3.Text = null;

It could be a couple of things.

127.0.0.1 is the loop back address to your machine, do you have a mail server running on your machine?
Do you have a firewall running and if so is Port 25 open to receive connections?

Solution 4

Are you setting the SmtpClient.Host property?

If this is not the problem, please let us see your code that uses a SmtpClient instance - probably LoginUtil.SendPasswordMail.
