======Total Rebuild of Database======

If you suspect database corruption, sometimes the best thing to do is to totally rebuild the database. This involves six steps:
  - Stop VPOP3
  - Backup Database
  - Delete Database
  - Re-create Database
  - Restore/Create Database
  - Restart VPOP3

The process may take 5-10 minutes, or more depending on the size of your database. If you want to check how long it will take before you start, then manually [[backup_vpop3#manual_database_backup|backup the database first]]. The full procedure will take approximately 3 or 4 as long as the database backup.

We have made a simple batch file to do this procedure for you. [[http://www.pscs.co.uk/downloads/vpop3/rebuilddb.zip|Download it]] and extract it into the main VPOP3 directory. Then, go to a command prompt in the VPOP3 directory and type 'rebuilddb'. It will ask for confirmation between each command in case problems occur.

You MAY get an error like this one - this can be ignored. It simply means that the restore was trying to create something which already existed.
