Which version of the DCC code are you using?
That can be determined with `cdcc -V` or `dccproc -V`.

What does `cdcc info` say?

Is there any chance that the DCC ./configure script is confused about
whether RedHat 9.0 understands IPv6?

It is much better to use sendmail+dccm and reject spam during the
SMTP transaction.  Of course, you'd need per-user whitelists
to determine which bulk mail is solicited.  

A poor second choice is to use sendmail+dccm with `dccm -Aignore` to
add X-DCC headers and teach SpamAssassin to look for X-DCC headers
containing "bulk." 

A worse third choice is to turn on dccifd and let SpamAssassin talk
to that daemon.

Using dccproc is a very distant fourth choice because it requires a
fork()/exec() of dccproc on every mail message.
