The problem with comparing eMail addresses (WP Support Plus Email Pipe)

Hello fix it please:

Plugin – WP Support Plus Email Pipe
File – /wpsp_email_pipe/includes/cron/class-create-pipe-ticket.php

Code from:

 if($agent_reply_status != '' && $user && $wpsupportplus->functions->is_staff($user) && $this->from_email != $ticket->guest_email){
                $ticket_oprations->change_status($agent_reply_status, $this->ticket_id, $this->from_name, $this->from_email, $this->user_id);
            }

            if($customer_reply_status != '' && $this->from_email == $ticket->guest_email){
                $ticket_oprations->change_status($customer_reply_status, $this->ticket_id, $this->from_name, $this->from_email, $this->user_id);
            }

Code to:

 if($agent_reply_status != '' && $user && $wpsupportplus->functions->is_staff($user) && mb_strtolower($this->from_email) != mb_strtolower($ticket->guest_email)){
                $ticket_oprations->change_status($agent_reply_status, $this->ticket_id, $this->from_name, $this->from_email, $this->user_id);
                 }

            if($customer_reply_status != '' && mb_strtolower($this->from_email) == mb_strtolower($ticket->guest_email)){
                $ticket_oprations->change_status($customer_reply_status, $this->ticket_id, $this->from_name, $this->from_email, $this->user_id);
                 }

Example: mainprovidec@yandex.ru and MainProvidec@yandex.ru

This is the same email, written in different ways. And because of this, your plugin does not change the Ticket status. And after editing, everything will work fine.
