Hmm.  Don't know if the DNSBL name is case-sensitive or not; you may
need all lowercase.

You need to rebuild the .mc file after making changes.  There should be
a .mc file named with your hostname--make your changes there.  Then use
make to rebuild it and install the new .cf file:

make all install

and then restart the daemon:

make restart

The contents of /etc/mail/Makefile are helpful.
