Answer 1

message.From = new MailAddress("sender#foo.bar.com");
And
<mailSettings>
<smtp from="nitinturankar3#gmail.com">
Must be the same!

Answer 2

You are using a username with empty space userName="NITIN TURANKAR", this is wrong

Answer 3

public string SendMail(string toList, string from, string ccList, string subject, string body)
{
System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage();
SmtpClient smtpClient = new SmtpClient();
string msg = string.Empty;
try
{
MailAddress fromAddress = new MailAddress(from);
message.From = fromAddress;
message.To.Add(toList);
//if (attachments != "")
//{
// message.Attachments.Add(new Attachment(attachments));
//}
if (ccList != null && ccList != string.Empty)
message.Bcc.Add(ccList);
message.Subject = subject;
message.IsBodyHtml = true;
message.Body = body;
// We use gmail as our smtp client
smtpClient.Host = "smtp.gmail.com";
smtpClient.Port = 25;
smtpClient.EnableSsl = false;
smtpClient.UseDefaultCredentials = false;
smtpClient.Credentials = new System.Net.NetworkCredential(
"Email", "password");
smtpClient.Send(message);
msg = "Successful<BR>";
string message1 = "Your Query has been Submited Successfully";
}
catch (Exception ex)
{
}
return msg;
}
try port replace to 587 Also.
