cbpadmin is responsible for deleting old entries from the database.
The script calls cleanup functions in the following modules:
Example:
If you have these set to 7 days and 1 day and if you have an email which is successfully delivered, the tracking entry (source IP/sender/recipient) becomes authed (ie. it passed the greylisting) and will not be deleted until it is 7 days old. If you have spam which fails to pass greylisting, it is unauthed and the tracking entry will be deleted when it is more than 1 day old.
Usage:
./cbpadmin [args] --config=/path/file Configuration file --debug Put into debug mode --cleanup Cleanup database records
