[Dovecot] Sieve/autosubscribe subfolder

[Moritz Augsburger]

Hi,

I just ran across the annoying issue, that with

lda_mailbox_autocreate = yes
lda_mailbox_autosubscribe = yes

set, parent folders of newly created subfolders get subscribed without
being existent.

Let me give an example:

In sieve I use
	fileinto "foo/bar";

but "foo/" does not exist as folder. So the Mailbox "foo/bar" gets
created, but without "foo/" being a Mailbox. Nevertheless gets "foo/"
subscribed, so that I have a non-existing mailbox in my subscription
list, what confuses thunderbird.

So, to solve this problem, I would propose
- either the implicit creation of foo/ as mailbox or
- not subscribing foo/
