I mistook your comment to mean you found it unusual, sorry. In my company we fight spam too, but a mailserver with a missing or incorrect reverse mapping is simply dodgy. It indicates poor admin practice, perhaps due to inexperience, carelessness - or simply a trojan.
Or someone with a bad ISP. Here I understand it is close to impossible to obtain reverse dns working right.
Especially when you reject the connection just because the PTR record is missing, or does not resolves to the hostname in the EHLO command. A better approach probably is to flag the mesasge as spam or as suspicious.
I agree with that, that's what we do too. However, I also understand the situation of large access providers - get rid of as much spam as possible whilst keeping costs low.
My ISP rejects mail as spam that is not spam, and I can do nothing about it. Sometimes it rejects email I send to myself, to another account (based on content analysis, I believe). - -- Cheers / Saludos, Carlos E. R.
