Hello, so as far as I understand this maildir and harddisk quota are two different things? And if I set the maildir quota of a user to 100MB but he can create 100 Mailboxes he can theoreticaly use 100*100 MB? The worst case would be if I set the Mailbox count to unlimited then theoreticaly the user could use up my whole harddisk space, right ? I've noticed another thing... Roundcube shows 30MB used and if i log into the ISPconfig panel under mail-quota it shows arround 80MB, whats happening here?
