Quite sure, yes. I was using it with Sendmail's DNSBL feature.

I remember the problem now. It wasn't a normal false positive. I
had legitimate users trying to relay through my server, rather than
other servers trying to relay mail to my users. They were being
rejected before they had a chance to authenticate. So, there's
probably nothing wrong with the zen list, I just couldn't use it in
that way, because I use the same server to handle both functions
(receiving incoming mail and relaying outgoing mail).
