If it is a Unix box, and if it follows conventions (standards?) you
could put "| /usr/bin/procmail" in a file called '.forward' in your
home directory.  Otherwise enjoy working with python instead ;-).

I believe Python's readline() keeps the newline character.

I am curious now as to your C++ compiler's environment.  
#include <string.h>
usually includes a header file that is part of the C standard library
and contains only C string manipulation functions.

#include <string>
will inlclude the C++ standard library's string class declaration.
(If the compiler conforms to the ANSI standard of leave the '.h' off
of include files)

Interesting that you include string.h and get C++ fuctionality from
it.  (I've tried before but get a "type expected instead of 'string'"
error message)
