> I agree, no rDNS would be a good rejection criterion if we could > assume everyone was following the standards, I hard block for no or generic rDNS and on HELO's that do not appear to be a valid domain name, on my "company" server and set SA scoring VERY high on "customer" servers (so it can be easily adjusted down on a per domain basis), but I often take the time and trouble to call the sender if I am notified of a "FP" (badly set up servers). Most often they are very grateful for the information as they often have had problems sending to other people as well. I recently had to contact PAYPAL about it !!! If more of us did the same, it would not take long for legit servers with no rDNS to be a thing of the past. > but I believe the > business reality prevents most of us from rejecting on that basis. Why ? Should we accept forged headers if its from a legit business ? Should we accept legit emails from known long term spam sources ? Should we accept mail from servers that break all the RFC's ? If we all rejected all bad mail, legit or spam, the "legit" servers would be forced to fix their bugs. AOL now block based on rDNS - all credit to them. The real problem is that not many of us are willing to make the stand.
