Hello,

I'm using Dovecot 2.2.30 with Pideonhole 0.4.18 and I'm having some problems, perhaps someone can give an hint on how to solve them.

When I try to create a folder in the toplevel directory of a shared mailbox, i get a "permission denied" although I have the rights, example:

1.doveadm -f table acl rights -u bob@example.com shared/bill@example.com Rights

lookup read write write-seen write-deleted insert post expunge create delete admin 2.doveadm mailbox create -u bob@example.com "shared/bill@example.com" doveadm(bob@example.com): Error: Can't create mailbox shared/bill@example.com: Permission denied

Creating an subfolder of a folder which already exists works fine:

1.doveadm -f table acl rights -u bob@example.com shared/bill@example.com /Drafts Rights

lookup read write write-seen write-deleted insert post expunge create delete admin 2.doveadm mailbox create -u bob@example.com "shared/bill@example.com /Drafts/Test" (no output) 3.doveadm -f table acl rights -u bob@example.com shared/bill@example.com /Drafts/Test Rights

lookup read write write-seen write-deleted insert post expunge create delete

So this works, but creating a folder directly in the inbox of the shared mailbox doesn't work and I don't know why. Is this not supported? Or do I miss something important?

Another problem I have is, that the private index files in shared folders are often to always marked as inconsistent in the dovecot log file, an example of such log messages look like:

• imap(bob@example.com): Error: /export/home/imap/bob@example.com/shared /bill@example.com/.Templates/dovecot.index.pvt view is inconsistent
• imap(bob@example.com): Error: /export/home/imap/bob@example.com/shared /bill@example.com/.Templates/dovecot.index.pvt view is inconsistent
• imap(bob@example.com): Error: /export/home/imap/bob@example.com/shared /bill@example.com/.Trash/dovecot.index.pvt view is inconsistent
• imap(bob@example.com): Error: /export/home/imap/bob@example.com/shared /bill@example.com/.Trash/dovecot.index.pvt view is inconsistent

And this is logged for almost every user who has access to a shared mailbox and I don't know how to stop getting the indexes inconsistent.

Here's my Dovecot configuration:

Any help is appreciated.

Many Thanks & best regards Thomas
