On ispc3 220.127.116.11, when I set mailbox quota limit over 2000 MB (ex. 3000MB), imap client and also roundcube shows mailbox quota unlimited. Possible bug, or it is just on my system? Same problem was also on 3.0.2 version. Second question, how can client check mailbox disk usage/free space via ispc3 cp? Is that possible? Maybe feauture request?
