iterate_query with static userdb ?
by Laura Smith 17 May '20

17 May '20

Hi, Going by the "static userdb" example on this page (https://wiki.dovecot.org/VirtualUsers#homedirs) tried to achieve a similar setup in conjunction with pgsql for passdb. However I get an error "auth: Warning: sql: Ignoring changed iterate_query in /etc/dovecot/local_sql_users.conf, because userdb sql not used. (If this is intentional, set userdb_warning_disable=yes)" Does this mean the following is not a valid config ? Or at least I will not be able to achieve iteration ? mail_location = maildir:/foobar/mail/%d/%n/Maildir passdb { driver = sql args = /etc/dovecot/local_sql_users.conf } userdb { driver = static args = uid=foo gid=bar home=/foobar/mail/%d/%n }

Hi, I'm trying to get dovecot working with postgres, I'm on Debian 10 and have installed dovecot-pgsql from the Dovecot repo (https://repo.dovecot.org/ce-2.3-latest/debian/....)

Fallback driver after autodection
by Bjoern Koenig 16 May '20

16 May '20

Dear developers and dovecot users, I am running a dovecot with virtual users that have a mailbox using the Maildir format. mail_location = maildir:/usr/local/virtual/%d/%n New mailboxes are created on-the-fly if a new user logs in. I had the wish that the mailboxes of new users are created using the sdbox format and old mailboxes remain in Maildir format. In case the Maildir and sdbox mailboxes already exist, it is easy to use the "auto" driver which detects the correct format. But it is not possible to create mailboxes with the "auto" driver because there is no way to tell dovecot the preferred mailbox format. I wrote some lines of code which add the possibility to specify a fallback driver that will be used if a mailbox is created with the "auto" driver. mail_location = auto:/usr/local/virtual/%d/%n:FALLBACK=sdbox In case you like the idea you might want to develop it further. I am aware of the fact that there are some caveats if you mix it with other settings like LAYOUT. It won't work in any case.

converting old uucp buffer files to maildir
by mh＠mike.franken.de 15 May '20

15 May '20

Hi *, besides my dovecot maildir structure, that has been migrated from an Exchange server, I have an even older mail structure in an ancient uucp style. The program named CrossPoint I used for this isn't wideley known, but it used so called mpuffer files in a plain text format. It is the program I still use to write for example this mail. I wonder if there already exists a program or script to convert the files from this program to the Dovecot maildir structure or some Howto for writing it myself. The format of these files looks like shown below.

doveadm sync backup from old to new server
by Gregory Sloop 15 May '20

15 May '20

So I've done quite a lot of searching on the list and on the web - and perhaps my google-fu is really bad - but I can't find any real recipes on how to sync mail from the old server to the new. As an FYI - the old server is a CPanel/WHM setup on a VPS. The new is mailcow - which uses docker. However, I don't think either of these platforms is what's causing the issue - but I'm certainly not sure of that. --- I've tried several things - but have lost track of all the things I've tried. This seemed like the best of all the things I've tried. This particular mailbox/user+domain is setup on both servers. doveadm backup -D -u mc-user(a)abc.net ssh root(a)abc.net -p2200 doveadm dsync-server -u cp-user(a)abc.net mc-user(a)abc.net is the MC/NEW mailbox/domain cp-user(a)abc.net is the CPanel/OLD user/domain account The SSH server of the remote system is running on port 2200. However when I try this, I get: WARNING: The WATCHDOG_NOTIFY_EMAIL variable is not set. Defaulting to a blank string. dsync-local(user(a)abc.net)<v44NFyRWvF5efgAAb6OASA>: Error: read(remote) failed: EOF (version not received) doveadm(user(a)abc.net): Fatal: execvp(ssh) failed: No such file or directory The process appears to hang, and a Ctrl+C stops it. I'd love to get pointed at a reasonable recipe on how to make this work. I don't really get/understand the docs much at all. [And either everyone else understands it just fine, and never thinks to write a document on how to do it - or, and I think this is a lot more likely - they're using something like imapsync to do it. I found numerous places where others were, essentially, "Dovecot's tool is way too complicated and I can't get it to work right, so I used imapsync." I suppose I should probably just do that too, but it does seem a shame to do that when the dovecot tool is almost certainly the best tool for the job, but I can't figure out how to use it.] If someone can help me grok what's going on, I'm glad to write it up for the list and or a blog entry so it's more accessible. TIA -Greg

[Dovecot v2.3.9.3] HTTP API Endpoint for mailbox cryptokey operations
by Thibault HUTTIN-PASSERON 14 May '20

14 May '20

Hello everyone, I successfully set up the mail_crypt plugin using folder keys, and require user's key to be encrypted with a password using mail_crypt_require_encrypted_user_key = yes. As I'm trying to streamline the process of creating a user, and want to develop an application in PHP to help me in that process, I'm very interested in the doveadm HTTP API. Although the mail_crypt plugin is not referenced in the API, I discovered that it could be accessed all the same, provided some camelCase changes. So far I've been able to generate the following json for the mailbox cryptokey generate command: curl -X POST -H "Authorization: X-Dovecot-API <base64-api-token>" -H "Content-Type: application/json" -d '[["mailboxCryptokeyGenerate",{"user":"<username>","userKeyOnly":true},"tag1"]]' http://localhost:8081/doveadm/v1 which is able to give me the same output as the related command: doveadm mailbox cryptokey generate -u <username> -U. This only works if a keypair has already been generated for the user, which is kind of counter-productive in my use case. I would like to know if there was a way to adapt the following command into a json API call : doveadm -o plugin/mail_crypt_private_password=<password> mailbox cryptokey generate -u <username> -U Especially the -o plugin/mail_crypt_private_password=<password> part, since it seems I've figured out the other part partly tinkering partly looking through the source code. Thanks everyone for your input.

Does Dovecot presently support the MULTISEARCH command, or are there plans to do so? --- Daniel
