Cannot delete folder

[Aki Tuomi]

This sounds more like misconfiguration to me. Can you provide doveconf -n and full output of namei -vl /full/path/to/mailbox

The issue still exists. Can anybody explain to me why dovecot creates 
IMAP folders with the wrong filesystem permissions? Every new folder 
that I create in the mailbox through Thunderbird (IMAP) has the wrong 
permission and cannot be deleted anymore.

This looks like a dovecot bug to me.

Hi there,

I cannot delete IMAP folders in new mailboxes. When trying to delete a
folder in Thunderbird I get the error message "renaming not supported
across conflicting directory permissions". Looking up the error on the
web led me to checking the mailbox directory's permissions. They're
inconsistent in new mailboxes. While every single directory in an old
mailbox has "drwx--S---", some of the directories in a new mailbox have
"drwxr-sr-x" instead. I'm not sure what that means. The folders with the
later permissions are "Drafts", "Sent" and "Trash". Folders with the
first permissions are "Junk", "Archives" and "Archives.2018". All
folders were created by Thunderbird automatically. Now I wanted to
delete "Archives.2018".

What's the issue here? Why do folders created by the same MUA in the
same event on the same mail server have different permissions and why
can't I delete one of them (which would probably move it into the trash
folder first)?

Dovecot version is 2.2.22 on Ubuntu 16.04, Thunderbird is 52.6.0 on
Windows 10.
