I thought I'd folo'd to the list on this, but I don't see it.

I was on CBL for some reason; no other lists.  I don't see any daemon spam 
coming out through my firewall, but, for some reason, I wasn't dropping it.

I am now.

Problem solved, and I've added another useful lookup tool to the outages.org
dashboard; MXtools, who were nice enough to tweet about it, so, more eyeballs.
