    Re: ip not resolving

    for the Warning - Reverse DNS does not match SMTP Banner - you need to contact your ISP and ask them to add reverse DNS and IP to their DNS server.

    The DNS tooks sometime to propagte the changes to the whole word. how long you've been waited? try use google DNS server, 8.8.4.4 see if it resolve to your ping and web request.
