When using require_once for things like IMP_BASE .  
'/config/header.php' and the file has
been included once already the second occurrence causes the $_header  
array to not be
defined and errors are issued to the user.  I changed line 133 of  
lib/MIME/Headers.php
substituting "require_once" with "require" to resolve the issue.  I  
only noticed the
issue when reporting spam.  Please excuse the lame report; I don't  
have time to chase a
proper patch (the usual cry from users).
