<br>
we're operating dovecot on a small server. Some years ago, we migrated<br>
from courier IMAP to dovecot. Therefore, we defined our default<br>
Namespace "inbox" with prefix "INBOX." to have this compatible. I found<br>
this in some migration docs those days. Generally, everything worked as<br>
expected.<br>
<br>
Our only namespace is configured like this:<br>
<br>
namespace inbox {<br>
separator = .<br>
prefix = INBOX.<br>
inbox = yes<br>
}<br>
<br>
Regularly, there is no folder named INBOX or .INBOX in the file system,<br>
I suppose this is correct. But I found a special corner case today when<br>
it comes to quota calculation.<br>
<br>
When - for whatever reason - a folder .INBOX.foo (for arbitrary values<br>
of foo) exists, the whole mailbox is counted twice in quota<br>
recalculation. Just creating .INBOX does nothing but a subfolder<br>
triggers the problem.<br>
<br>
This is my shell view (replaced username and file path and deleted<br>
unnecessary debug output)<br>
<br>
$ cat maildirsize<br>
268435456S<br>
14697 17<br>
$ maildirmake .INBOX.foo<br>
$ sudo doveadm -D quota recalc -u <user><br>
[...]<br>
doveadm(<user>): Debug: Namespace inbox: type=private, prefix=INBOX.,<br>
sep=., inbox=yes, hidden=no, list=yes, subscriptions=yes<br>
location=maildir:/home/.../test<br>
doveadm(<user>): Debug: maildir++: root=/home/.../test, index=,<br>
indexpvt=, control=, inbox=/home/.../test, alt=<br>

<br>
$ cat maildirsize<br>
268435456S<br>
29394 34<br>
<br>
<br>
So the used quota has exactly been doubled by just creating an empty<br>
subfolder.<br>
<br>
Do you have any pointers for fixing my configuration or is this a bug in<br>
dovecot?<br>
