Dovecot Version:
2.3.17 (8414c38c5c)
Dear,
Some troubles occur while we delete a folder via IMAP ssl command or via a IMAP client (different clients tested).
When we want to delete subfolder we observe following issues.
some examples following:
we created a folder with subfolders x/y/z
a02 CREATE x.y.z
a02 OK Create completed (0.003 + 0.000 + 0.002 secs).
response from dovecot cli
x
x.y
x.y.z
then we try to delete the z subfolder of x
a04 DELETE x.y.z
a05 OK Delete completed (0.002 + 0.000 + 0.001 secs).
The IMAP console returns success and the dovecot listing is ok
response from dovecot cli =
x
x.y
But dovecot status on x.y returns the folder is not existent
response from dovecot cli=
doveadm(u...@domain.tld): Error: remote(192.168.1.1:24245): Mailbox x.y: Failed to lookup mailbox status: Mailbox doesn't exist: x.y
vsize=0
This lead that physically the folder and sub folders are still in our storage but can not be accessed by the dovecot service.
We could bypass this phenomena by recreating this x.y folder and then delete the y folder again with IMAP.
a04 CREATE x.y
a05 OK Create completed (0.002 + 0.000 + 0.001 secs).
and status shows the folder exists
response from dovecot cli =>
vsize=0
Then we retry deleting the y folder from x
a08 DELETE x.y
a08 OK Delete completed (0.002 + 0.000 + 0.001 secs).
status still not correct for the top folder
response from dovecot cli =
doveadm(u...@domain.tld): Error: remote(192.168.1.1:24245): Mailbox x: Failed to lookup mailbox status: Mailbox doesn't exist: x
vsize=0
But this time without recreating the x folder, the delete command is working
a10 DELETE x
a10 OK Delete completed (0.001 + 0.000 secs).
the dovecot command shows no x folder anymore as wanted
response from dovecot cli =
a
a.b
a.b.c
No x folder appear in the listing
Is this a Dovecot problem ? our did it not be engineered for deleting top folder by IMAP?
Thanks in advance
Kind Regards
Pascal
