So far two spams got through this system in the 12 hours its been running (admittedly the early days are when its most effective, so I'll let you know how it goes in the coming days). Both came from open relays, and were detected on DNSBLs.
I need to modify this. One was an open relay detected by NJABL, and the other was a spam sent to a mailing list, and it got detected heuristically.
