Sto scrivendo un mail sender in C++ ma sono bloccato da un problema........

// main .cpp
#include <iostream>
#include <cstdlib>
#include <cstring>
#include "mail.h"

using namespace std;

int main( int argc, char *argv[] )
{
  
  system( "PAUSE" );	
  return 0;
}

#ifndef MAIL_H_
#define MAIL_H_
#include <string>

using namespace std;
// sending mail
void send( mail *, string, string, string, char*[] );
// the max size of mail object
#define BUFFER 2048

struct mail
{
    string from;// the sender
    string to;// the receiver
    string object;// the object
    char *text[BUFFER];// the text
    string header;// the complete header
};

void send( mail * ml, string from, string to, string object, char* text[BUFFER])
{
    if( ( from == " " ) || ( to == " " ) || ( object == " " ) || ( strcmp(text, " ") == true ) )
    {
        cout << "A part of the email is null, retry\t";
        return;
    }else{    
        ml->from = from;
        ml->to = to;
        ml->object = object;
        ml->text = text;
    }
    /* this part of function create the mail header and prepare it to send but I can't do at time :/ */
}
#endif
