doveadm REST API: Delete home
by Patrick Ben Koetter 24 Mar '21

24 Mar '21

Hi! How can I remove a users mail home directory using the REST API? I'm trying to purge a users mailbox including the users $HOME, but it seems I'm on the wrong way. If I send a mailbox delete I end up with "Error: Can't delete INBOX: INBOX can't be deleted.", which kind of makes sense. Should I be using https://doc.dovecot.org/admin_manual/doveadm_http_api/#doveadm-fs-delete instead?

Don't count namespace space in quota
by Pedro Ribeiro 24 Mar '21

24 Mar '21

Hello everyone! I'm trying to figure a solution for this scenario. I have the Dovecot IMAP using MDBOX (SIS) storage for the daily usage email. For long term storage I'm preparing a namespace with MBOX storage. I'm not using the altstorage logic because as far as I know it needs to have the same format as the base one and for archival I prefer to have the attachments inside the messages in an old/well known format supported by near any email software. The problem at the moment is with quotas. If the user has 5GB in his mailboxes and the long term "historico" namespace has another 5GB, the storage used becomes 10GB and I want the users to only see their "active" usage (5GB). I have that space to be ignored (as defined in the wiki and dovecot documentation - my quota_rule5 ) but it doesn't seem to influence the usage reported by IMAP. What am I doing wrong? If I put the "historico"namespace with disabled = yes and do a "doveadm quota recalc" the values become correct but I need the namespace available so the users can recover their old messages if needed. The relevant settings (AFAIK) I'm using are: plugin { quota = dict:FileQuota:ns=:file:%h/dovecot-quota quota2 = dirsize:HistQuota:ns=@HISTORICO/ quota_clone_dict = proxy::quota quota_grace = 10%% quota_rule = *:storage=24G quota_rule2 = Trash:storage=+128M quota_rule3 = Junk:storage=+64M quota_rule4 = INBOX:storage=+128M quota_rule5 = ns=@HISTORICO:ignore } namespace historico { disabled = no hidden = no ignore_on_failure = yes inbox = no list = no location = mbox:/mnt/mail-hist/historic/%d/%-2.2n/%n:SUBSCRIPTIONS=.imap/dovecot-subscriptions:LAYOUT=maildir++ order = 0 prefix = @HISTORICO/ separator = / subscriptions = yes type = private } namespace inbox { disabled = no hidden = no ignore_on_failure = no inbox = yes list = yes location = order = 0 prefix = separator = / subscriptions = yes type = private } userdb { args = /etc/dovecot/dovecot-sql.conf.ext auth_verbose = default default_fields = home=/data/domains/%d/%-2.2n/%n lport=%{lport} driver = sql } best regards to all the Dovecot community, stay safe! -- Best regards, =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Pedro Ribeiro Politécnico de Lisboa, Serviços da Presidência Departamento de Sistemas de Informação e Comunicações Phone: +351 210 464 700 (general) / VoIP: 80100 Helpdesk: helpdesk(a)net.ipl.pt / https://www.net.ipl.pt =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

Custom sql queries in acl-plugin
by Matthias Kneer 23 Mar '21

23 Mar '21

Hi, I would like to allow users to use any known "alias" of another user to grant permissions to their mailboxes. Here's the scenario: A user, with an internal name "example@12345" and an alias "test(a)example.org". The domain "12345" is only used internally to separate the customers into different directories, therefore "anotheruser" only knows the address "test(a)example.org" grants folder permissions to "test(a)example.org". This results in the following: +-------------------------+--------------------------------------------+-------+ | from_user | to_user | dummy | +-------------------------+--------------------------------------------+-------+ | anotheruser@12345 | test(a)example.org | 1 | +-------------------------+--------------------------------------------+-------+ But since the actual username is "example@12345" the proper directory can't be found. I would like to achieve the following outcome, with the same user inputs: +-------------------------+--------------------------------------------+-------+ | from_user | to_user | dummy | +-------------------------+--------------------------------------------+-------+ | anotheruser@12345 | example@12345 | 1 | +-------------------------+--------------------------------------------+-------+ Is it possible to populate the to_user column with a more dynamic sql lookup instead of the dict lookup? Thanks in advance, Matthias

prevent INBOX rename
by mj 22 Mar '21

22 Mar '21

Hi, One of our users managed to rename her INOX folder to ' ' (space) This caused a new INBOX directory to be created, and all older emails to become 'invisible' to her. My question: Is there a (dovecot config) way to prevent this from happening? We cannot image any scenario where we would like a user to be able to rename INBOX. > imap(username)<12135><bsJbjpO9gN7AV48G>: Mailbox renamed: INBOX -> Debian buster, dovecot 2.3.4.1 Thanks!

feature request: maintain folder structure with expunged email
by Marc 22 Mar '21

22 Mar '21

Currently when I am expunging messages, the expunged (to be purged messages) are counted / listed at INBOX. Say for instance that a user would accidentally delete the mailbox 2014. The whole folder structure below it would be lost. If someone creates a folder structure, this folder structure has important added value. I have my doubts on this design discarding of mailboxes like this. I think the use of mailboxes/folder structures is not valued enough. If you have a lot of email and put these emails in folders, the folder structure is part of the important information. Currently this 'important information' is lost with expunging. I can understand that it maybe quite an effort to implement preserving this information. But using the doveadm import to restore a lot of emails, is really not an option. I assume that also restoring email from a specific folder does not work. Say I delete foldera, folderb and folderc. How can I get back folderb.

Is it possible to use per user keys with mail-crypt-plugin when using passwd-file backend?
by Davy Landman 21 Mar '21

21 Mar '21

I've been reading quite a bit of discussions, the manual and a few often linked posts about mail-crypt-plugin, but most of them seem to assume a sql db backing. But if you are using a passwd file userdb, is it possible to make the per-user-key mode of the mail-crypt-plugin work? I like the trick of passing in the key via an extra calculated/virtual column in the query (even allows for hashing the password for example). But I cannot see how this can work with the passwd backing? Any pointers would be appreciated. Kind regards, Davy (Why so focussed on passwd files? I'm using the docker-mailserver setup that takes care of a lot of messy setup, so I rather not redo that just so that I can switch to a db for storing the user details of maybe 2 to 3 users)

FW: imapsieve rules not matching at all?
by dovecot＠steve.wattlink.net 20 Mar '21

20 Mar '21

Greetings! I feel like this has been beaten to death, but my searches on the web (and about 10 hours spent over the last two days) haven't revealed what's going on. Basically, it's the usual "I'd like to auto-learn spam/ham based on moves to/from a folder" problem. But in my debugging, I don't see any evidence that the static rules are matching, so the scripts aren't running, which makes me think I'm missing something obvious. Below I list doveconf -n output, and some log snippets. In my experiments, I've tried removing the report-spam.sieve and report-ham.sieve scripts, and absolutely nothing changed, which is why I think the rules aren't being tried.
