Using rtrim to determine when to break is invalid per RFC 822, which  
per section 3.1 (http://tools.ietf.org/html/rfc822#section-3.1) states  
headers are separated from the body by a null line; nothing preceding  
the CRLF.  rtrim incorrectly strips tabs, thus skipping the remaining  
headers

Example:

S*T*R*I*P*P*E*D
