[dovecot] quota

[Sebastian Pachuta]

first, thx for --with-storages=maildir

second, there is a problem when user exceed their quota

< status INBOX (messages)
> NO Internal error [2003-05-06 15:35:56]

in logfile:
imap(user): Can't create directory /var/mail/user/.INBOX: Disk quota exceeded

'user' is not able to get list of messages and delete some of them :(

third,

in logfile:

imap(user2): maildir flags update:
rename(/var/mail/user2/cur/1049405360.18375_0.asd,
       /var/mail/user2/cur/1049405360.18375_0.asd:2,T)
failed: Disk quota exceeded

is there any way to rename files when quota exceed?
