Hmm - in my case my rDNS setup seems ok though except for the fact that 2 octets are in my ptr record which I'll be fixing tonight. But that's not the rule I was tripping. Here's another example from a test email sent from one of my virtual domains netbits.us: 5.0 BOTNET Relay might be a spambot or virusbot [botnet0.7,ip=209.18.107.89,hostname=netbits.us,maildomain=netbits.us,baddns] <snip> > If you think there is a case where Botnet breaks down for > multiple/virtual mail domains, where DNS and rDNS are properly set > up, put your money where your mouth is and give a real world > example.

Personally, I like Botnet, but it does seem like I have a real world example where my rDNS is setup fine. Unless I missed something? Thx, Josh
