Ofcourse there is, but you'ld have to modify spamassassin.
There should be a line with something similar to Net::DNS::Resolver->new;

If you change that to $res   = Net::DNS::Resolver->new(LocalPort => xx);
where xx is the port rbldns is listening on, it should work. This is
not documented, but it is directly from the source.
