Our way uses extra boolean 'flag' fields in an SQL DB, but 'extra' fields, are
by no means limited to an SQL DB.

Ergo, you can use ONE file, and ONE lookup operation, just return the
'audit_flag', 'quarantine_flag', etc. at the same time you pull the rest of the
addressee-specific information.

Put a test for the flag(s) into your archiver/shadow router(s) and call
appropriate transports...

- or use what you have retrieved to alter the storage location..
