/*                _build_headers()

 */

function _build_headers() {

        // creation du header mail

        $this->headers= "From: $this->from\n";

        $this->to= implode( ", ", $this->sendto );

        if( count($this->acc) > 0 ) {
                $this->cc= implode( ", ", $this->acc );
                $this->headers .= "CC: $this->cc\n";
        }

        if( count($this->abcc) > 0 ) {
                $this->bcc= implode( ", ", $this->abcc );
                $this->headers .= "BCC: $this->bcc\n";
        }

        }

        $this->attachment= implode($sep, $ata);
}


} // class Mail
