Ubuntu8.04,AMD64 I added a user with the right email address but wrong username. I deleted it, also emptied recycle bin. The user is not in any table I could find in the MySQL server, it does not have a folder, or que in \var\mail, there also isn't such a user in the users list for linux. Even though when trying to add it again I get "The username is already in use." WHERE THE HELL IS IT IN USE?!!!!!
