Interesting scenario ... but would be far more interesting to us if you share the /24?

I'm confused.  Who are you billing and for what services?


Let's say our direct customer is CustomerA.  They seem to buy rackspace from
BusinessB.  CustomerA seem to retain BusinessC for "IT Solutions" even
though all three entities purport to be IT solutions providers.
BusinessC came into the picture after the spamming started saying a wholly
different /24 (Different from the spam source) "doesn't work".  It routes
fine on our end.  I have a feeling they've been added to some RBLs but I
haven't found them listed yet.

Just a simple ethernet handoff in a colo.  We delegated rDNS to the servers
of their choice and haven't heard a peep out of them until now.



Spamhaus is the first one that comes to mind.  From what I understand of
your description, this doesn't sound all that different from typical spammer
behavior.  Multiple layers of indirection seems to be the latest thing for
spammers.
