I have a user who has several folders in his mailbox, which we can not delete, neither via IMAP nor via doveadm:

root@ka-nfs-mail:~# doveadm mailbox list -u <username> | grep hbereiche | cat -v INBOX/[Fachbereiche ^M INBOX/Fachbereiche ^M INBOX/hbereiche^M INBOX/hbereiche/LAGen]^M INBOX/hbereiche/LAG^M INBOX/[Fachbereiche^M INBOX/[Fachbereiche/LAGen]^M INBOX/[Fachbereiche]^M INBOX/[Fachbereiche]/LAGen]^M INBOX/[Fachbereiche]/LAGe^M root@ka-nfs-mail:~# doveadm mailbox delete -u <username> 'INBOX/Fachbereiche ' doveadm(<username>): Info: Mailbox deleted: INBOX/Fachbereiche root@ka-nfs-mail:~# doveadm mailbox list -u <username>| grep hbereiche | cat -v INBOX/[Fachbereiche ^M INBOX/Fachbereiche ^M INBOX/hbereiche^M INBOX/hbereiche/LAGen]^M INBOX/hbereiche/LAG^M INBOX/[Fachbereiche^M INBOX/[Fachbereiche/LAGen]^M INBOX/[Fachbereiche]^M INBOX/[Fachbereiche]/LAGen]^M INBOX/[Fachbereiche]/LAGe^M

As far as I tried none of these folders can be deleted (I added single quotes for trailing space and tried to delete subfolders first).

Mailbox is in mdbox format on a replication pair under Dovecot 2.2.36 and I tried both nodes of the replication with same result.

Any ideas?

can you turn on mail_debug=yes and run doveadm -Dv mailbox delete and provide output and logs from both servers?

root@ka-nfs-mail:~# doveadm mailbox list -u <username> | grep hbereiche | cat -v INBOX/[Fachbereiche ^M

I haven't seen this idea and you've wrote nothing about the ^M:

The ^M means that there is a "\015" / \r at the end of the output. Where does this char come from? In "normal" output, this char is almost invisible, esp. at the end of a line. I don't know how Dovecot handles this char internally.

The char should show up in the JSON formatted list, Aki suggested, too:

doveadm -fjson mailbox list -u user INBOX/*

But I haven't seen the output in your replies.

Can you verify in the filesystem, if the char is there, too? E.g. ls -1 | cat -v

Maybe

doveadm mailbox delete -u <username> 'INBOX/Fachbereiche '"\015" Would help?

I haven't seen this idea and you've wrote nothing about the ^M:

The ^M is the regular CR from the doveadm output converted by cat -v and I used it to show there is a trailing space.

...

The ^M means that there is a "\015" / \r at the end of the output. Where does this char come from? In "normal" output, this char is almost invisible, esp. at the end of a line. I don't know how Dovecot handles this char internally.

root@ka-nfs-mail:/poolN/dovecot/imap/<domain>/<user>/mdbox/mailboxes# ls -1|cat -v|grep hbereich [Fachbereiche [Fachbereiche [Fachbereiche] Fachbereiche hbereiche

So there is no ^M/CR in the filename itself.

I found a way to reproduce the problem :)

Use an arbitrary mailbox (maybe my Dovecot config with mdbox etc. required). Then use Thunderbird (52.9.1 on Mac) to create eg. the following folder (without the quotes!):

"[Test / Test]"

This is a space, a slash and a space between the Test in square brackets.

TB now creates the following two folders:

"INBOX/[Test " (not subscribed)
"INBOX/[Test / Test]" (subscribed)

I can delete the 2. one, but the 1. one is not deletable, neither via TB nor doveadm command:

/ # doveadm mailbox status -u bb@bb-trunk.egroupware.de all 'INBOX/[Test ' doveadm(bb@bb-trunk.egroupware.de): Error: Mailbox INBOX/[Test : Failed to lookup mailbox status: Mailbox doesn't exist: INBOX/[Test / # doveadm mailbox delete -u bb@bb-trunk.egroupware.de 'INBOX/[Test ' doveadm(bb@bb-trunk.egroupware.de): Info: Mailbox deleted: INBOX/[Test / # doveadm mailbox list -u bb@bb-trunk.egroupware.de 'INBOX/[Test ' INBOX/[Test

I can see the folder under mdbox/mailboxes and in mdbox/subscriptions.

I hope that allows you to reproduce it.

One more update, I tried renaming that "[Test " folder to just "Test", which creates an also not deletable folder "Test".

Good news is, if I delete these folders on both replication nodes from mdbox/mailboxes and mdbox/subscriptions they seem to be really gone. I can event create the folder "Test" again and it behaves normal aka. I can delete it afterwards via IMAP.

Any objections againts that workaround (deleting the folder in mdbox/mailboxes and from mdbox/subscriptions)?

Actually you are using separator /, so making folder

INBOX/[Test / Test] =>

"INBOX" sep "[Test " sep " Test]"

but it will not create "INBOX/[ Test " (it will be noselect folder, parent for "INBOX/[Test / Test]")

and thus will be deleted once you delete INBOX/[Test / Test]

"doveadm(testuser1): Error: Can't delete mailbox INBOX/[Test : Mailbox has children, delete them first"

also mailbox list has feature that it will always list whatever folder you give it, so even if you do

doveadm mailbox list "This Does Not Exist"

you will still see it. A feature, not a bug. =)

you could try

doveadm exec imap -u victim LIST "INBOX/" "*"

to see which are the select, and which are the noselect parent ones, they should go away once you delete the children.
