I have a really strange (urgent) issue in relation to sending an email via a php script.
I need to know if the mail() part of this script can send an email to any location (even if it is on another domain). I just setup a test scinearo where I had the php script on our server and had the email sent to me, which worked fine. I then changed the mail address to my clients email address - and the emails didn't get though.
$subject = "TEST: " . $_GET['ID'] . "-" . date("Ymd H:i:s");
mail("email@example.com",$subject,"", "From: firstname.lastname@example.org");
header("Refresh: 0; URL=" . $_GET['Hyperlink'] . "");
