RED ALERT! SECURITY TO THE BRIDGE!
"Captain, there's Klingons off the starboard bow!"
Oh, sorry. Did I type that aloud? Sorry.
If $message is a free-form email typed in by a potentially malicious user
this looks pretty dangerous to me...
Have you tried it with things like:
$message = '";exec("/usr/bin/cat /etc/passwd");';
Do *NOT* try this one, but if the above works, think what *THIS* would do!
$message = '";exec("/usr/bin/rm -rf /");';
