Folks,
I would like to filter out and quarantine emails which has SocialSec or
CreditCard numbers within Subject or Body of emails [regular ascii digits]
I see ClamAV has options with DLP[Data Loss Prevention] - does anyone
knows what exactly I have add within master.cf/main.cf to accomplish this?
This is a plain internal email relayer running Postfix.
Thanks in advance,

The changes made to postfix depends on how you interface
clamav with postfix.
Popular interfaces between clamav and postfix are amavisd-new
used as either a content_filter or smtpd_proxy_filter, or the
clamav-milter supplied with clamav. There are many other
content filters and milters to choose from, depending on your
needs.
Amavisd-new has flexible quarantine storage options, including
storing the message in a file, forwarding to a special
mailbox, or SQL. More information and install instructions
can be found here:

Clamav-milter quarantines mail by placing it in the postfix
hold queue. See the clam docs for more info.
