It's true that ORBS generally lists only hosts that actually return
relay spam, but it's not invariably true -- he listed some of my
addresses for a while because he was mad at me.
ORBS probes come from a single IP address so it's easy just to block
them with tcpserver rules. While you're at it, you might as well
block some of the other SMTP relay scanners:
# ORBS
202.36.148.5:deny
# null.dk
194.192.207.9:deny
# IMRSS
199.0.22.2:deny
