Somebody (Christian Huietma?) did a survey, and 30% of the sites don't even have working PTR entries in the DNS. Why should you expect enough buy-in on updating LDAP entries to make the query worth trying? www.rfc-ignorant.org has a very large database of sites that can't even get things like '[email protected]' and '[email protected]' *email* addresses correct. So you end up penalizing sites that don't have a clue, while the clued spammers will do this: % ldap add abuse_contact mailbox="[email protected]" % cat > ~abuse/.forward /dev/null ^D What have you won? -- Valdis Kletnieks Computer Systems Senior Engineer Virginia Tech Attachment:
