ah yes, MAPS.

Not last time I checked. Reasons like this are why we are no longer
subscribers. The zone is just too large to keep copying via zone xfer, and
MAPS did not have IXFR working when we left (we spent many hours trying to
get it to work).
If they would convert to rbldnsd and rsync, we'd probably go back. But
there are other, free DNSBL that meet our needs.
