Sending email in asp.net via local host server

Question

Is there any example that can explain me to send email from my localhost server ? I've written this example but it doesn't work the error is "Failure sending mail".

 SmtpClient smtpClient = new SmtpClient();
        smtpClient.Host = "localhost";
        smtpClient.Port = 25;
        smtpClient.EnableSsl = false;
        smtpClient.Credentials = new NetworkCredential("mostang1970@yahoo.com", "secret");
        smtpClient.Send("mostang1970@yahoo.com", "hadinematipartow@yahoo.com", "Let’s eat lunch!", "Lunch at the Steak House?");//here is the error

And what should i do in web.config?

For testing purposes we can use localhost like this: How to Test Email Without Configure SMTP in ASP.NET

In case the link goes down again, basically we have to modify web.config like this:

  <system.net>
    <mailSettings>
      <smtp deliveryMethod="SpecifiedPickupDirectory">
        <specifiedPickupDirectory pickupDirectoryLocation="C:\Mails\"/>
      </smtp>
    </mailSettings>
  </system.net>

and C# code

  MailMessage mailMessage = new MailMessage();
  MailAddress fromAddress = new MailAddress("mail@mail.com");
  mailMessage.From = fromAddress;
  mailMessage.To.Add("mail@mail.com");
  mailMessage.Body = "This is Testing Email Without Configured SMTP Server";
  mailMessage.IsBodyHtml = true;
  mailMessage.Subject = " Testing Email";
  SmtpClient smtpClient = new SmtpClient();
  smtpClient.Host = "localhost";
  smtpClient.Send(mailMessage);

This will output a file to our desired directory.

You need to specify the settings for your SMTP server in web.config. There are several example online (eg this )

<system.net>
    <mailSettings>
        <smtp deliveryMethod="Network" from="test@mydomain.com">
            <network host="smtp.mail.com" userName="name@mydomain.com" password="pwd" port="25"/>
        </smtp>
    </mailSettings>
</system.net>

Then you can simply use the SmtpClient class to send:

SmtpClient smtpClient = new SmtpClient();
smtpClient.EnableSsl = true;

MailMessage msg = new MailMessage();
msg.To.Add("recipient@email.com");
msg.Subject = "test";
msg.Body = "test body";

smtpClient.Send(msg);

here is the sample:

public static void SendMailMessage(string from, string to, string bcc, string cc, string subject, string body)
{
    // Instantiate a new instance of MailMessage
    MailMessage mMailMessage = new MailMessage();

    // Set the sender address of the mail message
    mMailMessage.From = new MailAddress(from);
    // Set the recepient address of the mail message
    mMailMessage.To.Add(new MailAddress(to));

    // Check if the bcc value is null or an empty string
    if ((bcc != null) && (bcc != string.Empty))
    {
        // Set the Bcc address of the mail message
        mMailMessage.Bcc.Add(new MailAddress(bcc));
    }      // Check if the cc value is null or an empty value
    if ((cc != null) && (cc != string.Empty))
    {
        // Set the CC address of the mail message
        mMailMessage.CC.Add(new MailAddress(cc));
    }       // Set the subject of the mail message
    mMailMessage.Subject = subject;
    // Set the body of the mail message
    mMailMessage.Body = body;

    // Set the format of the mail message body as HTML
    mMailMessage.IsBodyHtml = true;
    // Set the priority of the mail message to normal
    mMailMessage.Priority = MailPriority.Normal;

    // Instantiate a new instance of SmtpClient
    SmtpClient mSmtpClient = new SmtpClient();
    // Send the mail message
    mSmtpClient.Send(mMailMessage);
}

And call the function:

SendMailMessage("fromAddress@yourdomain.com", "toAddress@yourdomain.com", "bccAddress@yourdomain.com", "ccAddress@yourdomain.com", "Sample Subject", "Sample body of text for mail message")

 bool ret = true;

            try
            {
                string _smtpServer = ConfigurationSettings.AppSettings["appEmailHost"];

                Web.Mail.Mail mail = new Web.Mail.Mail(_smtpServer,         
        System.Web.Mail.MailFormat.Html, System.Web.Mail.MailPriority.Normal);
                mail._From = test@test.com;
                mail._To = Test2@test.com;
                mail._Subject = subject;

                mail._Body = body;
                mail.SendMail();
                ret = true;
            }
            catch(Exception exp)
            {
                _GravaErro(exp);
                ret = false;
            }

            return ret;
