Are those lines in /var/dcc/whiteclnt?

Is that file writable by the dccm process, including not locked by
an editor such as `vi`?

Are there any complaints about the contents of /var/dcc/whiteclnt
from dccm in your system log?

What are the contents of /var/dcc/log files containing mail that
was rejected but should have been accepted?  Dccm always says why
it doesn't like a message in the log files it creates.

One way to debug a DCC client whitelist is to feed mail messages
to `dccproc -w whiteclnt -l /tmp -E -S ...`

Client-IDs are assigned by DCC server owners for their own DCC clients.
If your mail system handles more than 100,000 mail messages per day,
then you should have your own DCC server and assign your own client-IDs.
If your mail system handles fewer mail messages, you should probably
use the public DCC servers.

Please do not send HTML encoded messages to this mailing list.
I don't think much of sending both cleartext and HTML in any case,
but perhaps I'm a radical reactionary.
