Hi,

this is not a setting in your email account: it is an extra line of code like
Code:
$email = $_REQUEST['email'];
if(ereg("[\r\n]", $email)) exit;
A real user of your form would not send newlines, since the input is not multiline.
A bad guy might target a html form at your script and send
Code:
[email protected]
Bcc: [email protected] [email protected] [email protected]
and all these people would get the bad guy's rubbish message from your server
