Solution

Try This..... You meed to pass clear(TRUE) to clear attached file after mail send.

        path_to_the_file = "/data/mail-attachment/";
        $attachfile = $path_to_the_file . $mailinfo->attachment;

        //SET COMMON VARIABLES
        $fromname = "[email protected]";
        $subjectline = $mailinfo->subjectline;
        $this->load->library('email');
        $message = $mailinfo->mailbody;
        $message .= "<br /><br /><a href=\"$attachfile\">Download Attachment</a>";
        $emailto = array();
        foreach ($maillist as $key => $value) {
            $emailto = $value->email;
        }
        $this->email->set_newline("\r\n");
        $this->email->from($fromname);   // change it to yours
        $this->email->to($emailto);   // change it to yours
        $this->email->subject($subjectline);
        $this->email->message($message);
        $this->email->attach($attachfile);
        $this->email->set_mailtype("html");
        if ($this->email->send()) {
            $this->email->clear(TRUE);
            $success_mail_count++;
        }
