You could add the addresses of people you email to the list (perhaps with a timeout).

If you still want to send me email, go to this web site, fill in the form and I'll let you know. Have a nice day". Actually, people do this already and there are procmail scripts floating about to implement this if you try google. A similar varient is if I don't know who you are, I reply with a nounce nd you must then resend with that nounce or I won't accept your email... so on-off spamming doesn't work. --cw - To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog
