No, because (a) if the message were several 10's of megabytes long (or
more) you'd have problems and (b) $message_body turns newlines into
spaces. The WishList items about this read thus:

------------------------------------------------------------------------------
(304) 02-Nov-04 M A way of seeing the whole message in Perl or ${run           


At present, the headers are available in $message_headers, but only part of   
the body is visible. The only way to pass the whole body would be as a file   
descriptor because it can be very large. See also (42).                        
------------------------------------------------------------------------------


------------------------------------------------------------------------------
(42)  23-Apr-02 T  An option not to flatten newlines in $message_body.       


Or maybe better to provide $message_body_nl so as to have both.
