    If one finds oneself stuck with an rdns-less IP, there's an unhappy
    workaround of relaying through the ISP's designated relay server. Your
    inbound mail will still work because the MX will still point to an A
    record that points to your IP address, and I've never heard of any mail
    server that refuses to deliver to based on a lack of rdns.
