Hi Anton,

Thank you very much for your helpful hint. Thunderbird clearly wants to 
move Public/Test to the Trash of the user who subscribed the Public 
folder. Question is how to solve this from a Dovecot point of a view, so 
a user can also delete folders?

INBOX has To Wait = FALSE can run = FALSE
