Is the value of mail_host in the log files
for the rejected messags?  If so, then adding '-S mail_host' to
DCCM_ARGS in /var/dcc/dcc_conf and adding the line

    ok	substitute	mail_host

should white-list that mail.

Because the Yahoo groups are reported to have a significant spam
problem, it might be better, if possible, to use entries in 
per-user white lists instead of a global white list entry.
The sample CGI scripts support pointing-and-clicking to add a
white list entry for mail_host values found in log files provided
dccm is running with -S mail_host.
