I recommend exporting all your messages to the PowerMail Exchange
format, then importing to a new, clean, message database:
- export "your entire mail database" to the PowerMail Exchange format,
without attachments
- quit PowerMail
- after having backed up your whole PowerMail database folder, delete
the "Message Database", "Message Database index" and "Message Database
Spotlight cache" files
- launch PowerMail while pressing the command and option keys, and check
"temporarily disable scheduled connections" (especially if you have mail
filters that move received messages to a folder)
- import the messages from the exported file
- all your mail filters that move messages to a folder will have lost
the reference of the destination folder, so verify and fix all your mail
filters manually
- quit and relaunch PowerMail (to re-activate scheduled connections)

If exporting "your entire mail database" fails, you can select a few
folders and export "the selected mail folders". If this fails on a
folder, you can select a range of messages in the folder and export "the
selected messages".

Low level database rebuild is really something that should only be
performed when your database is damaged. If you want to make sure it is
intact, rebuilding the search index should be enough, as it will proceed
every message in the database; or even better, export to the PowerMail
Exchange format, you will get an extra backup in a non-database format.
