Mail form problem

Hi I have a very simple mail form on a site I am making

it just has

Name
Email address
Send

Very Basic

It works well and mails the information to me for the new signups, perfectly

However
I want to change this so that it can use autoresponder from Gmail

I want when the customer enters his name email
he gets an autoresponse from gmail (vacation response)
saying, welcome to the Site, please now click the following links etc etc

The problem?
Gmail auto responder responds to the EMAIL address of emails that it recieves

When it recieves mails generated from html pages like that, it cannot tell the actual email address to send the auto reply to

How do I program the page so that the email address that the person submits to me in the form
is the
email address that
gmail replies to with the auto reply

 

I take it you're using something like:

mail("blah@blah.com","Email Title","You have been contacted by someone from your site");

PHP:

If so, then you can add a header to that and it will show who it's came from.

mail("blah@blah.com","Email Title","You have been contacted by someone from your site","From: " . $_POST['email']);

PHP:

Something along those lines, should work for you.

 

You will need to add more headers otherwise most email services will put it straight in the spam box.
