VPOP3 2.x usually uses SQLite 2.8.3 as its database engine. This stores databases in discrete *.db files in the VPOP3\_database directory on the server PC. We do not recommend that you access these databases directly unless you know what you are doing, and we strongly discourage the alteration of data in the databases directly unless technical support request you to.
Whilst VPOP3 is stopped, certain database files can be deleted if they are corrupt without causing major problems, others can be deleted, but will cause problems if they are. If any database is deleted, VPOP3 will automatically create a new (empty) one when it restarts. Below is information about deleting the databases. Note that we do not recommend deleting any of the databases in normal operation (otherwise VPOP3 would delete them for you, or they simply wouldn't be made).
