my server's hostname is and IP is
my mail server is and IP is
IP block owner set the PTR record for my mail server

I changed the hostname in to (it was and sent a test email to gmail account but the client-ip is still and the email contained "Received: from ( [])".

Currently ISPConfig 2 and postfix are installed with CentOS5.
