If a similar line is seen in your system log, then are using
/var/dcc/whitecommon.  As I wrote in response to that
message in
the solution is to review your /var/dcc/whitecommon and /var/dcc/whiteclnt
files.  You should delete bad lines and add needed lines to those files.

Unless you copy (manually or automatically) information from the
MailScanner whitelist to the dccifd or dccproc /var/dcc/whiteclnt
file or vice versa, the MailScanner and DCC whitelist mechanisms
are independent.

If you really don't want to use the DCC whitelist mechanism, 
empty /var/dcc/whiteclnt.
