Miquel van Smoorenburg and others seem to think that they do need to
match.  if you connect to my IP, you will see that neither 24.22.127.210
nor cc659474-a.indnpls1.in.home.com appear in the greeting.

I do not appear to be listed with the DUL, so far as I know.  A couple of
hosts seem to reject 24.* or something, but I'm not overly worried about
them.  I _AM_ worried about people who want to make it worse by adding
additional arbitrary requirements before they accept mail related to
Debian.

It's somewhat amusing that the blacklist people seem to have blacklisted
eachother, though.
