I have a SmarterMail server with about 15.000 users on 5 different domains. I have noticed that each user has a stat file for each month on the server. Those files are taking up more storage than the mail they have on the server.
I have configured "Delete User Stats After x months" and changed it from the default of 13 months to only 5 months. So far nothing has happened. My question is when does the cleanup take place?
