PHP mail function 'from' address

Question

I\'m not even sure this is possible, however what I\'m trying to do is as follows. I have an HTML form that generates and email using a PHP script. What I want

Answer 1

For a php mail script I have used this for contact forms:

$from = $_POST["from"];  //posted from the form.

mail("me@myname.com", $subject, $message, "From:" . $from);

I have not used a sendmail_from in my php before, only a simple variable.

I hope this helps!
