I couldn't find anything relevant between all the debug log lines. Is
that in /var/log/mail.log?
Here's the lines I think are related to creating and deleting the folder:
> May 21 10:36:14 mond2 dovecot: imap(yg@****.de): Debug: Namespace : /var/mail/virtual/****.de/yg/.Test doesn't exist yet, using default permissions
> May 21 10:36:14 mond2 dovecot: imap(yg@****.de): Debug: Namespace : Using permissions from /var/mail/virtual/****.de/yg: mode=0700 gid=default
> May 21 10:36:23 mond2 dovecot: imap(yg@****.de): Debug: Namespace : /var/mail/virtual/****.de/yg/.Trash.Test doesn't exist yet, using default permissions
That's it.
Thunderbird shows an error message with: [CANNOT] Renaming not supported
across conflicting directory permissions (0.000 + 0.000 secs).

Assuming '8' = mail, i cannot see anything wrong here...
Can you turn on 'mail_debug=yes' and attempt folder deletion, and check
logs after that?
