Well, copied code is always a system gremlin.

I figured out why I didn't notice it was an email subject--

+             $subject = htmlspecialchars (trim ($subject), ENT_QUOTES);

Why call htmlspecialchars on an email subject? I know it's copied 
code. Doesn't mean the original code is correct.

Oh, and according to RFC2822 section 2.2.3, CRLF is allowed in a 
subject as long as it is at the front of other white space.
