I currently have ClamSMTP and ClamAV 0.97.3 installed on CentOS with
postfix and dovecot. The setup works and ClamAV properly scans all emails
and detects viruses. However, I have enabled the DLP module in Clamd to
detect CC numbers and SSNs and lowered the threshold to 1 for each. When I
send and SSN number Clam properly logs that there was a SSN attempted to be
sent. When I send any formatted Credit Card number, ClamAV does not
recognize that there is a credit card number contained in the body of the
text or as an attachment.

Does anyone have any knowledge about this? Am I missing something? lists
