SHA-256 hash them. The search space for possible e-mail addresses being so large, it's not practical to brute force the hashes back into valid e-mail addresses (unlike phone numbers, where you just brute-force the search space by dialling them all and hassling whoever answers). Of course, just having a giant list of "do not spam" hashes isn't helpful without regulatory teeth, which is the main reason why such a system isn't likely to get up and running any time soon -- since you can spam from anywhere, avoiding regulation is not particularly difficult. - Matt _______________________________________________ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
