Re: Affects of the balkanization of mail blacklisting

IIRC, MAPS hasn't allowed free zone transfers for quite some time.

Whether or not it's really "stolen" is for MAPS to think about and a judge
to decide (if MAPS decides to go that route).  The big problem with this
is is saying "go complain to MAPS", but MAPS can't help.
Obviously, they don't want people stealing it, or they wouldn't have
removed the CIDR text version of the DUL from their web site.

I don't have access to a zone file to check, but I suspect MAPS would have
been setting a relatively small expire time on the zones so this sort of
thing wouldn't happen without someone at editing the zone and
making themselves a master for it.  If they did that, why didn't they
update their mail servers?

The point is, if everyone creates their own DUL, and those DULs are poorly
maintained and have no documented procedures for submissions and
deletions, it's going to be a major PITA for network operators as their
customers complain "this IP space is no good, it's in DULs all over the
net, give me some virgin IP space."
