Sending email problem by Gmail account

Hi,

I'm trying to send a email in C# using Gmail. I want the 'from' header to have another my own specified email address whenever user receive email. Could anyone please tell me how can I do this?


MailMessage mailMsg = new MailMessage();
SmtpClient client = new SmtpClient();

client.Port = 587;
client.Host = "smtp.gmail.com";
client.EnableSsl = true;
client.Credentials = new System.Net.NetworkCredential(username, password);
MailAddress mailAdd = new MailAddress("[email protected]");

mailMsg.Sender = new MailAddress(username);
mailMsg.From = mailAdd;
//mailMsg.Headers.Add("Sender",username);
mailMsg.Bcc.Add(builder.ToString());

mailMsg.Subject = txtSubject.Text;
mailMsg.Body = txtBody.Text;
mailMsg.IsBodyHtml = chkHtmlBody.Checked;
if (System.IO.File.Exists(txtAttechments.Text))
{
System.Net.Mail.Attachment attechment = new Attachment(txtAttechments.Text);
mailMsg.Attachments.Add(attechment);
}

client.Send(mailMsg);

In above code 'username' and 'password' fields contain another email address and password. The received email having 'from' header with value of 'username' filed.

I do this a similar way. I tested the following code and it works fine:

Code:

---

        SmtpClient client = new SmtpClient();
        MailMessage message = new MailMessage();

        message.Body = "Hello, there!";
        message.From = new MailAddress("[email protected]");
        message.Sender = new MailAddress("[email protected]");
        message.To.Add(new MailAddress("[email protected]"));
        message.Subject = "Hi!";

        client.Credentials = new NetworkCredential("[email protected]", "mypassword");
        client.EnableSsl = true;
        client.Port = 587;
        client.Host = "smtp.googlemail.com";

        client.Send(message);

---

It just uses the email accounts user name and password, but the From field in gmail always shows up as "me". Odd...
