As I always say, wanted bulk mail should be whitelisted.  One of the many
ways to whitelist this mailing list is by adding the following to a global 
/var/dcc/whiteclnt file, to relevant per-user whiteclnt files, or
perhaps to a /var/dcc/whitecommon or server /var/dcc/whitelist file:

OK      env_from    dcc-admin@rhyolite.com

One could also whitelist by IP address.   If you are running dccm,
dccifd, or dccproc with -SList-ID as in the comments in the example
/var/dcc/dcc_conf file or the /var/dcc/dcc_conf-new file generated by
updatedcc, you could also use

OK  substitute List-ID: Distributed Checksum Clearinghouse <dcc.rhyolite.com>

See also the sample whitecommon file in the DCC source, perhaps at

In this particular case, it appears that a subscriber to this mailing list
is reporting it with `dccproc -cMANY` or some other spam-trap mechanism.
