- bot at triband-* sent junk to silly.server.example.
- silly.server.example didn't reject it. instead it bounced it to OP
- the bounce includes infos about which host sent the original junk to
silly.server.example, and this is triband-*

so for OP, this is backscatter, and RBL/DNSBL is of no help.
