Since I was the one who gave you this advice: you can send e-mail perfectly fine without having any DNS record for your server. However, as Barney already pointed out, the MXs of other domains may refuse to accept mail from your server unless it does have valid DNS records. That's one of the reasons why you'd normally relay mail from such hosts through some "official" mail server (e.g. your company's or your ISP's MTA). The "null client" standard configuration example to which I had pointed you used a relayhost (for a number of other reasons, too). Why didn't you stick with that?
