Experimenting with dcc

Hi,
I've discovered several emails that hit DCC, most likely because they
contain just emails or are entirely empty, so I wanted to whitelist them.

However, I'm not sure how to write the checksums to the whiteclnt file so
they are consulted by dcc:

# /usr/bin/dccproc -QCw whiteclnt < whitelist-email-example.eml
X-DCC-debian-Metrics: xavier.example.com 1169; Body=0 Fuz1=0 Fuz2=0
                            reported: 0               checksum  server
                 env_From: d41d8cd9 8f00b204 e9800998 ecf8427e

What am I missing? The whiteclnt file is owned by root:root which is how
it's set in the fedora40 RPM. The documentation is very long-winded. Maybe
I missed something?
