I guess I meant that it makes it harder for the spammer if he/she gets a copy of the list to casually look for addresses to avoid without doing the extra work of encoding the address in the same way and looking it up. But with fresh eyes this morning the benefit of this is tenuous - it just means that they have to do a bit of extra work ;-) My idea for creating an emailBL was in the vain hope that if I could get it to work well enough that the actual mailbox providers hosting the dropboxes might actually use it to terminate the mailbox provided I let them see evidence for each address (I know - probably no chance of that; but I can hope). I'm also thinking of doing the same with 'full URIs' that cannot be listed by the existing URI blacklists due to the spammers abusing services specifically to avoid the existing lists so they don't burn up an actual domain name e.g. http://groups.yahoo.com/groupname/message/1 would be as easy as: s...@laptop-smf:~$ perl -MDigest::MD5 -e '$uri="http://groups.yahoo.com/groupname/message/1";; print Digest::MD5::md5_hex($uri).length($uri).".bl.org\n"' f499f872e8276a4777c3dba48481915a43.bl.org Cheers, Steve.
