Maybe the whole thing IS actually also a dovecot issue... When trying to create a folder with a dot with thunderbird (which doesn't simply forbid this)... it actually transmits the folder name to dovecote (e.g. "kernel.org")... but dovecot then literally takes this over and creates .kernel.org, i.e. no encoding and thus org becomes a subfolder.
Cheers, Chris.
