Looks like the radioactive spider that bit me was from the control group because there was no tingling of my spidey sense :) I echo the point of email servers being assigned a real rDNS to cut down on heartburn. Thankfully one of BULK's features ensures real RRs can easily coexist within a synthesized range.
