 You should replace 'localhost' and port in

smtpClient.Host = "localhost";
smtpClient.Port = 25;

with your real smtp server & port number

 For example if you will use Gmail account to send emails

 

// Smtp configuration
    SmtpMail.SmtpServer = "smtp.gmail.com";//smtp is :smtp.gmail.com
      // - smtp.gmail.com use smtp authentication
    mailMsg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", "1");
    mailMsg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", "[e-mail]");
    mailMsg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", "mypassword");
    // - smtp.gmail.com use port 465 or 587
    mailMsg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpserverport", "465");//port is: 465
    // - smtp.gmail.com use STARTTLS (some call this SSL)
    mailMsg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpusessl", "true");
