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 'postmaster@' and 'abuse@' *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
