Having gone through this with Spamcop in the past and being on relatively good terms with the people who work there, I think you’ll find that they possibly did forsee the impact of the change, but decided that the problems experienced by companies continuing to send mail to users who never opted in and/or who have been sending to domains rejecting emails for years were not of much concern to them. Last time I talked to a SC employee, which admittedly was more than a few years ago, about their trap conditioning they were using a 2+ year cycle of actively rejecting mail to trap domains. If your users can’t figure out how to stop mailing domains that never accept a single email over the course of 2 years, I don’t think that’s really a trap maintainer problem. I’ve taken the position, and tell my clients this, that EVERY SINGLE EMAIL that bounces is a potential spamtrap.This has been reinforced by the commercial services selling access to spamtrap data - where the spamtrap data is simply domains maintained by the commercial service. If your customers are bouncing mails then your response should be “they hit a spamtrap” not some vague “oh, well.” laura -- Having an Email Crisis?
