Hi all, I do have a mailbox-quota problem in dovecot 2.0.19 that is beond my understanding. Could someone pls. give me a hint.

- user1 max. mailbox quota is set to 1GB, the current mailbox size of user1 is 15MB
- user2 max. mailbox quota is set to 10MB, the current mailbox size of user1 is 10kB
- user1 shares the folder 'shared_folder' to user2 with all rights (read, write ...)
- user2 has subscribed to 'shared_folder'

the problem:

- user2 tries to move a mail (20kB) to the shared folder via telnet: ". copy 1:1 shared/user1/shared_folder"
- it fails with: "NO [OVERQUOTA] Quota exceeded (mailbox for user is full)"
- copying the same mail to a local folder of user2 works without problems.
- After I raised the max. mailbox quota of user2 from 10MB to 16MB it was possible to move the mail to the 'shared_folder' of user1.

It looks like the copy operation fails because the mailbox size of user1 is exceeding the quota limit of user2! Is this possible? Is this a bug? Do I have a configuration problem?
