I don't think that's really going to work. You can configure a slave
server to do domain transfers on alternate ports, but that's about it.
Everything else expects DNS servers to answer on port 53. You'ld be
better off adding an alias address to the server and making each
server bind each to it's own address.  Don't know about rbldnsd(8),
but for bind9 you can put entries like this within the options{}
section of named.conf:

    listen-on {
        127.0.0.1;
        12.34.56.78;
    };
    query-source    address 12.34.56.78 port 53;
    transfer-source 12.34.56.78 port 53;
    notify-source   12.34.56.78 port 53;

(Nb. you can change the port number that bind uses in the 'listen-on'
statement but as I said above, there's not a great deal of use in
doing that)

See file:///usr/local/share/doc/bind9/arm/Bv9ARM.html for details.

	Cheers,
