from the text, there is no way to see whether the guy is right or wrong. there is no evidence. I doubt Trend Micro _require_ "smtp/mail/...". they may recommend it. but they certainly accept mail from a lot of servers whose name has no smtp/mail/... in it. as for sorbs, my experience is that they will easily unlist any host that was listed by error. (I am talking about duhl). so in my opinion, this is just blah blah blah blah. and yers, it is reasonable to block ad\d+\.$domain, because "ad" generally means "active directory", which has no business sending mail. sure, one should be free to name his mail server, but we are free to block what looks like a ratnet. this includes things like 2.3.4.5.static.example.com,however static it is. if you want to send mai in these spam days, the least we ask you is to "name" your server.
