When you delete an entry in Vibe, it goes to trash. In addition, there's a directory on the Vibe server called "archivefilestore" where deleted (even purged I think) attachment live on forever.

Just like there's the ability to configure Vibe to delete old versions of attachments after X days (we have ours set to 180), there should also be the ability to set this for archive and trash.

Right now my Vibe server has over 100Gb worth of trash and archive that I'd like to see automatically managed. The configuration for this (default: off, or 365 days) should be under "Message Database Logs and File Archives".
