Reading from a scalar (or filehandle) should handle folded and unfolded 
headers just fine in the input.  Are you having problems with the input or 
the folding of headers when outputting the message after you've modified 
it?  (Mail::Box defaults to folding headers if they exceed 78 characters.) 
Can you post some example code and output that shows the problem your having?

For reference, here's how I use Mail::Box as a procmail filter for spam 
tagging:

<>; # ignore the "From_" line that procmail adds
my $msg = Mail::Message->read(\*STDIN);
$bb->tagmsg( { msg=>$msg, %options } ); # A Mail::Classifier object
print $msg->head->createFromLine;
$msg->print;
