Hello,

The "new" way of creating default mailboxes doesn't work for us. There seems to be a permission problem.

We get this in the logs: imap(testuser@domain.com): Error: nfs_flush_file_handle_cache_dir: rmdir(/var/mail) failed: Device busy

That error message has nothing to do with NFS (not used) or /var/mail and appears every time an app is requesting a list of folders via IMAP and only if we enable the autocreate feature.

We're using mdbox, emails are delivered via LDA and the folder permissions look like this:

la /home/user/imap/domain.com/testuser/mdbox/mailboxes/

total 5 drwx------ 3 user mail 3B Jan 5 19:33 INBOX drwx------ 3 user mail 3B Jan 5 19:33 . drwx------ 4 user mail 8B Jan 7 02:43 ..

The mailbox definitions used come straight from the wiki: http://wiki2.dovecot.org/MailboxSettings

I've enabled debugging, but there is no mention of the mailboxes to create: Debug: dict quota... Debug: Namespace : type=private, prefix=, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes location=mdbox:~/mdbox Debug: fs:... Debug: acl:... ...

Here is what works:

• Autocreate plugin
• Creating folders via various clients

So, it seems Dovecot can create folders, just not using that feature. If that's not a bug, would there be a way to make it work without altering permissions?

Cheers,

Olivier
