How to send an email with user email, in contact us page?

I am creating a contact us page, and i want to receive mails from this page as its a mail came from the user mail.

I wrote this code:

var client = new SmtpClient("smtp.gmail.com", 587)
                {

                    EnableSsl = true
                };
                MailMessage mail = new MailMessage();
                mail.From = new MailAddress("userEmail@any.com");
                mail.To.Add(new MailAddress("mymail@gmail.com"));
                mail.Body = "bodyTest";
                mail.Subject = "subjectTest";
                client.Send(mail);

But i receive the mail from my mail not the user

How to do this?

Using gmail, the message will come from the user logging in, not the user in the "from". You can put whatever you'd like in the from, but it doesn't work the way you'd expect.

Using a small, free Google Apps account, I've actually set up a 'bot@example.com' account. I log into gmail with that account, so at least contact mail has that as the from.

I also encountered the same issue, and there is kinda workaround for this, you can add the sender's email to the ReplyToList property, which will give the option to reply to that address.
