======msgaudit Database table======

This can (optionally) contain data showing how messages have been handled (eg deleted, moved, etc)

  * id - incrementing ID of msgaudit entry
  * datetime - the date & time the event occurred
  * component - which VPOP3 component performed the event
  * owner - which VPOP3 user owned the message
  * actionuser - which VPOP3 user performed the event
  * cmd - the command which occurred
  * ipaddr - the IP address the event was triggered by
  * sourcefolder - the folder the message was in at the start of the event
  * targetfolder - the folder the message was in at the end of the event (if it was different from the sourcefolder)
  * subject - the message subject
  * sender - the message sender
  * msgdate - the message date

Note that this logs commands sent to VPOP3's message store, NOT commands sent by the user, so it may not match what you think is happening. For instance, if a user deletes a message, you may see a copy to another folder (eg 'Trash'), then a bit later a message delete, then a bit later a message purge/expunge. That is how the 'delete' operation is actually performed in the background.
