I have sent mail several times using the technique several times before but somehow it doesnt work i am providing the code in the following:

MailMessage myMailMessage = new MailMessage();
            myMailMessage.Subject = "Response From Client";
            myMailMessage.Body = "hello word";
            myMailMessage.From = new MailAddress("[e-mail]", "jub");
            myMailMessage.To.Add(new MailAddress("[e-mail]", "Softden"));

            SmtpClient mySmtpClient = new SmtpClient();
            mySmtpClient.Send(myMailMessage);

and my web.config is:

<mailSettings>
      <smtp deliveryMethod = "Network" from="Jubair &lt;[e-mail]&gt;">
        <network defaultCredentials="false" enableSsl="true" userName="[e-mail]" password="Mypassword" host="smtp.gmail.com" port="587"></network>
      </smtp>
    </mailSettings>

it says the smtp server requires a secure connection or the client was not authenticated.. Please help

Answer 1

Try adding something like this
Per Dominic’s answer on Stackoverflow look at he following example

using System.Net;
using System.Net.Mail;

var fromAddress = new MailAddress("[e-mail]", "From Name");
var toAddress = new MailAddress("[e-mail]", "To Name");
const string fromPassword = "fromPassword";
const string subject = "Subject";
const string body = "Body";

var smtp = new SmtpClient
           {
               Host = "smtp.gmail.com",
               Port = 587,
               EnableSsl = true,
               DeliveryMethod = SmtpDeliveryMethod.Network,
               //UseDefaultCredentials = false,
               Credentials = new NetworkCredential(fromAddress.Address, fromPassword)
           };
using (var message = new MailMessage(fromAddress, toAddress)
                     {
                         Subject = subject,
                         Body = body
                     })
{
    smtp.Send(message);
}

//—————– A simple approach below —————
I just tested this below and it works

var mail = new MailMessage();

// Set the to and from addresses.
// The from address must be your GMail account
mail.From = new MailAddress("[e-mail]");
mail.To.Add(new MailAddress(to));

// Define the message
mail.Subject = subject;
mail.IsBodyHtml = isHtml;
mail.Body = message;

// Create a new Smpt Client using Google's servers
var mailclient = new SmtpClient();
mailclient.Host = "smtp.gmail.com";//ForGmail
mailclient.Port = 587; //ForGmail


// This is the critical part, you must enable SSL
mailclient.EnableSsl = true;//ForGmail
//mailclient.EnableSsl = false;
mailclient.UseDefaultCredentials = true;

// Specify your authentication details
mailclient.Credentials = new System.Net.NetworkCredential("[e-mail]", "xxxx123");//ForGmail
mailclient.Send(mail);
mailclient.Dispose();

//The .config settings there are two options on how you could set this up I am suspecting that this is the issue you are having

<system.net>
    <mailSettings>
      <smtp from="[e-mail]" deliveryMethod="Network">
        <network userName="[e-mail]" password="mypassword" host="smtp.gmail.com" port="587"/>
      </smtp>             
    </mailSettings>
  </system.net>

or option 2

<configuration>
    <appSettings>
        <add key="smtpClientHost" value="mail.localhost.com"/> //SMTP Client host name
        <add key="portNumber" value="587"/>
        <add key="fromAddress" value="[e-mail]"/>
    </appSettings>
</configuration>
