I'm using mail function.
How I can make that if email address is not correct email will return back to me not to administrator of server?
Thank you...
RTFM! (http://www.php.net/manual/en/function.mail.php)
mail("recipient@example.com", "the subject", $message, "From: me@mycompany.com", "-fme@mycompany.com");
The last parameter specifies where to deliver the error messages.
You need PHP 4.0.5+ BTW
