I've seen a lot of examples using the php mail function. Some of them use rn as line break for the header, some use n.
$headers = "From: Just Men"; $headers .= "Reply-To: Just me <$email>n";
$headers = "From: Just Mern"; $headers .= "Reply-To: Just me <$email>rn";
which one is correct?
Sometimes I've had cases where rn is used and part of the header is interpreted by some email clients as mail text (losing these header information) - is this because rn is wrong?
