      {
          SqlConnection conn = new SqlConnection(@"Data Source=.\SQLEXPRESS;AttachDbFilename=E:\MVC3\TelerikLogin\TelerikLogin\App_Data\Login.mdf;Integrated Security=True;User Instance=True");

          DataTable dt1 = new DataTable();

          string strQuery = string.Format("SELECT user_password FROM [user_master] WHERE user_email_address='{0}'",user_email_address);
          conn.Open();
          SqlDataAdapter da1 = new SqlDataAdapter(strQuery, conn);
          da1.Fill(dt1);
          conn.Close();

          if (dt1.Rows.Count > 0)
          {
            //....Here is the code for sending a mail.....

              MailMessage msg = new MailMessage();

              msg.From = new MailAddress("direction@gmail.com");
              msg.To.Add(user_email_address);
              msg.Subject = "Password";
              msg.Body = "Test";
              msg.Priority = MailPriority.High;

              SmtpClient client = new SmtpClient();


              client.Credentials = new NetworkCredential("direction@gmail.com", "direction", "smtp.gmail.com");
              client.Host = "smtp.gmail.com";
              client.Port = 587;
              client.DeliveryMethod = SmtpDeliveryMethod.Network;
              client.EnableSsl = false;
              client.UseDefaultCredentials = true;

              client.Send(msg);

             return RedirectToAction("MailTransfer", "MailT");
          }
          return View();
      }

It gives me an error on below line

client.Send(msg);

And Error is:

The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.0 Must issue a STARTTLS command first. x1sm1264662igc.16

I wanna solve this error.. so need help....

Use the below code to sent Email:

C#

MailMessage msg = new MailMessage();
msg.From = new MailAddress("yourID@gmail.com");
msg.To.Add("sendID@yahoo.com");
msg.Body = "body my mail";
msg.Subject = "my mail subject";
msg.Priority = MailPriority.High;

SmtpClient client = new SmtpClient();
client.Credentials = new NetworkCredential("yourID@gmail.com", "yourName", "smtp.gmail.com");
client.Host = "smtp.gmail.com";
client.Port = 587;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.EnableSsl = false;
client.UseDefaultCredentials =true;

client.Send(msg);

Use this code

C#

public int SendUserMail(string fromad, string toad, string body, string header, string subjectcontent)
   {
       int result = 0;
       MailMessage usermail = Mailbodplain(fromad, toad, body, header, subjectcontent);
       SmtpClient client = new SmtpClient();
       //Add the Creddentials- use your own email id and password
       client.Credentials = new System.Net.NetworkCredential("your user id ", "pwd"); ;

       client.Host = "smtp.gmail.com";
       client.Port = 587;
       client.EnableSsl = true;
       try
       {
           client.Send(usermail);
           result = 1;
       }
       catch (Exception ex)
       {
           result = 0;
       } // end try

       return result;

   }
   public MailMessage Mailbodplain(string fromad, string toad, string body, string header, string subjectcontent)
   {
       System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage();
       try
       {
           string from = fromad;
           string to = toad;
           mail.To.Add(to);
           mail.From = new MailAddress(from, header, System.Text.Encoding.UTF8);
           mail.Subject = subjectcontent;
           mail.SubjectEncoding = System.Text.Encoding.UTF8;
           mail.Body = body;
           mail.BodyEncoding = System.Text.Encoding.UTF8;
           mail.IsBodyHtml = true;
           mail.Priority = MailPriority.High;
       }
       catch (Exception ex)
       {
           throw;
       }
       return mail;
   }

For error...

The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.0 Must issue a STARTTLS command first. x1sm1264662igc.16

...you need to set EnableSsl to true

C#

client.EnableSsl = true;

for more information, check this answer on StackOverflow[^]. Note the main differences when setting up the SmtpClient

C#

var smtp = new SmtpClient
           {
               Host = "smtp.gmail.com",
               Port = 587,
               EnableSsl = true,
               DeliveryMethod = SmtpDeliveryMethod.Network,
               UseDefaultCredentials = false,
               Credentials = new NetworkCredential("name", "password")
           };
