Some years ago when changing the inbound gateways for a major North American mailbox provider, we ran a trial for about three weeks on a set of IPs. That trial was ended and the new gateways turned on with different IPs a few weeks later, but we found that spambots were still trying to use the trial IPs over a year later. It made for a great spamtrap feed :-) --Kurt Andersen
