If you are running a recent Postfix, the MIMEDefang milter seems like
a reasonable choice for this. It has a 'quarantine' function that
drops a copy of the message as offered along with various bits of
metadata into a directory of its own for easy examination later, and
you can still reject the message in SMTP. The trick for keeping the
messages is to not do the DNSBL check until you have the data in
hand, and MIMEDefang will let you do that (or anything else you can
whip up some perl for)
