[Mimedefang] Greylist cleaner script problem

The DB file is a binary chunk on the disk, which has records allocated in it as
required.  When a record is deleted, the space is marked as available, but
nothing else - you would not expect to see the size of the file decrease.

To shrink the file, you'd have to modify the script to tie a second hash to a
new database, copy the contents of the main hash to the second as you process
the records if the record is still valid, untie the hashes, and then move the
live database to a backup file, and the new database to be the live one.  In the
meantime, you have to either stop MIMEdefang/SA, or have it cope gracefully with
the greylist being unavailable - Jonas' code will return a tempfail if the
database is unavailable, so if the first thing you do is rename the file, all
should be well while it is being processed, and it will immediately come back
into action when the new file is installed.

Best Wishes,

Paul.
