But that would be an interesting exercise. When spam does arrive, take the IP of the mail server and see if it's in ORBS.
A quick test got me 54 matches from 178 addresses from my spambox from the last 2-3 months, or about 30% -- the proportion over just the last month (88 messages, 30 hits) is about 34%. That's better than I had expected, but filtering based on headers gives a hit rate of around 90% and works without involving external agencies and their policies. Of my filters, the one that traps messages lacking a To: address to me is the most effective, although mailing lists have to be allowed for. Open relay spam mostly has bogus To: addresses, so using an open relay blocker of any colour would buy me very little. -- don --------- To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog
