I used to block bad rDNS servers.. then I needed to get some emails from Texas 
Instruments (yes, ti.com) and they had bad DNS... I told them about it (through 
the customer tech support line which is really for semiconductors, but seemed to 
be the best place to start...) and they just didn't care...

So I finally gave in and turned off rDNS checks... which were blocking like 2000 
spams a month for me. :(
