compiled sieve files svbin ?

Hi, I have recently started using claws mail to manage my user sieve scripts using server dovecot-sieve_1%3a2.3.13+dfsg1-2_arm64.deb I originally edited ~/.dovecot.sieve to hold my script and I recall that ~/.dovecot.svbin was automatically generated on first use. (either that or I have forgotten that I had used sievec) Later I used claws mail to generate sieve scripts but they were written into directory ~/sieve/ In experimentation I changed ~/.dovecot.sieve into a link to my principal script ~/sieve/main.sieve The oddity now is that sieve seems to be working when there is no compiled version Should I expect a compiled .svbin version to be generated from claws client? Or generated by first run of the sieve server on the user account? Or should I manage the scripts with claws, but log in to the server later to generate the .svbin versions? In any event what effect does not having a .svbin version have on typical small installation? -- Jeremy

Subject line says it all? I am using Roundcube, and every time i click on "filters" i get RC's "unable to connect to server" message. This might be an SQL error, but i can't figure out how to pull the relevant logs yet. Please see below and any advice you have is so very appreciated SYSLOG: ------------------- Nov 22 10:29:27 mail roundcube[66295]: <keirks4p> PHP Error: Connection refused (GET /index.php?_task=settings&_action=plugin.managesieve) Nov 22 10:29:27 mail roundcube[66295]: <keirks4p> PHP Error: Unable to connect to managesieve on obfuscated.domain:4190 in /usr/local/www/roundcube/plugins/managesieve/lib/Roundcube/rcube_sieve_engine.php on line 221 (GET /index.php?_task=settings&_action=plugin.managesieve) Nov 22 10:29:27 mail roundcube[66295]: <keirks4p> PHP Error: Not currently in AUTHORISATION state (GET /index.php?_task=settings&_action=plugin.managesieve) Nov 22 10:29:27 mail php[66295]: <keirks4p> PHP Error: Not currently connected (GET /index.php?_task=settings&_action=plugin.managesieve) Nov 22 10:29:31 mail roundcube[66295]: <keirks4p> PHP Error: Connection refused (GET /index.php?_task=settings&_action=plugin.managesieve-action&_framed=1&_nav=hide) Nov 22 10:29:31 mail roundcube[66295]: <keirks4p> PHP Error: Unable to connect to managesieve on obfuscated.domain:4190 in /usr/local/www/roundcube/plugins/managesieve/lib/Roundcube/rcube_sieve_engine.php on line 221 (GET /index.php?_task=settings&_action=plugin.managesieve-action&_framed=1&_nav=hide) Nov 22 10:29:31 mail php[66295]: <keirks4p> PHP Error: Not currently connected (GET /index.php?_task=settings&_action=plugin.managesieve-action&_framed=1&_nav=hide) Nov 22 10:29:43 mail roundcube[71055]: <keirks4p> PHP Error: Connection refused (POST /?_task=settings&_action=plugin.managesieve-save) Nov 22 10:29:43 mail roundcube[71055]: <keirks4p> PHP Error: Unable to connect to managesieve on obfuscated.domain:4190 in /usr/local/www/roundcube/plugins/managesieve/lib/Roundcube/rcube_sieve_engine.php on line 221 (POST /?_task=settings&_action=plugin.managesieve-save) Nov 22 10:29:43 mail roundcube[71055]: PHP Warning: Trying to access array offset on value of type null in /usr/local/www/roundcube/plugins/managesieve/lib/Roundcube/rcube_sieve_engine.php on line 1065 Nov 22 10:29:43 mail php[71055]: <keirks4p> PHP Error: Not currently connected (POST /?_task=settings&_action=plugin.managesieve-save) DOVECOT.LOG: ------------------- Nov 22 10:28:58 mail roundcube[66297]: <keirks4p> [43CD] C: A0008 LOGOUT Nov 22 10:28:58 mail dovecot[8514]: imap(obfuscated(a)user.name)<8609><XgBCqxHusXAKAAAB>: Disconnected: Logged out in=219 out=1045 deleted=0 expunged=0 trashed=0 hdr_count=0 hdr_bytes=0 body_count=0 body_bytes=0 Nov 22 10:28:58 mail roundcube[66297]: <keirks4p> [43CD] S: * BYE Logging out Nov 22 10:28:58 mail roundcube[66297]: <keirks4p> [43CD] S: A0008 OK Logout completed (0.001 + 0.000 secs).

Dovecot 2.2 to 2.3 migration
by Markus Wienhöfer 17 Nov '22

17 Nov '22

Hi, we are currently using Dovecot 2.2 (from the Ubuntu 18.04 repos) and would like to migrate to 2.3 I have read the migration documentation regarding the configuration changes. Apart from that, is it feasible/possible to change from Ubuntu to official Dovecot repositories and upgrade the dovecot package this way? Or is there anything else we should be aware of? Best regards Markus

Doveadm backup stateful synchronization trouble
by dovecot＠f-hamelin.fr 16 Nov '22

16 Nov '22

Hi, The non-blocking error is: doveadm(user1s@domain): Error: Saved sync state is invalid, falling back to full sync: Invalid base64 data This error occurs every time on my test machine (no traffic, only a few test messages). That error sometime also occurs on my production system, but not each time. The command I used for the first time is : doveadm backup -A -s "" -d > state.txt After that there is a daily calls (as vmail user, my config only handle virtual users) to : doveadm backup -A -s "$(<state.txt)" -d > state.txt.tmp && mv state.txt.tmp state.txt doveconf -n output is available at https://www.f-hamelin.fr/pub/doveadm-backup-doveconf.txt Any help will be welcomed Best regards, Franck

OAUTH2 local validation
by Felix Auringer 16 Nov '22

16 Nov '22

Hello, <https://doc.dovecot.org/configuration_manual/authentication/oauth2/#local-v…> describes how to set up local validation for OAUTH2 with dovecot. This works fine as long as the keys are not rotated. In my experience, it is common for a client to try to validate a token with the cached key and update the cached keys when the local validation fails (e.g. via the /auth/realms/<realm>/protocol/openid-connect/certs endpoint in Keycloak). This way, the client does not need to fetch new keys periodically but only when the old ones expired. If I understand it correctly, Dovecot reads the keys from a defined path but does not care how to update them. Did you have a nice way in mind how the keys should be refreshed when deciding not to do that in dovecot? Are you planning to add automatic refreshing of local validation keys to dovecot? I am running dovecot in Docker and one way would be a cron job on the host that fetches new keys and updates the files inside the container via docker exec. It would work but it's not really a nice solution because from outside dovecot, the information whether the old keys are no longer valid, is not available and the whole process needs to run periodically (and thus way more often than actually necessary).

Re: bug: ARGON2 hash selection incompatible with LDAP

I cannot specify bind_dn template due to mismatched mail addresses and user DNs, and I thought that that would be suboptimal due to re-binding. I am a bit confused about how to optimize LDAP lookups now (static files not option :), re-reading the docs it just made me question more things - auth_bind_dn cannot be given in my case, as a fixed starting point - auth_bind adds a temporary binding (using pass_filter) - can I use userdb prefetch? Docs say I cannot if I use bind with template, but I am not using the latter. So the search for the user's dn during auth IS the passdb lookup? - assuming I am correct, I should give back stuff with passdb lookup: or do I? - Must I give back userid an guid? 10-mail.conf has "vmail" for both, as mail accounts don't have UNIX ones linked to them... - same for home? There is no default I've given until userdb lookup. Just specify a global mail_home with variables, and get on with life? -if I should give back one, should I pass it with default_fields = userdb_home (currently I specify it under default_fields:home in userdb lookup as LDAP doesn't override home). The docs are confusing around userdb. The main thing what is not clear that they CAN override fields on a per-user basis, but must they provide them for non-extra fields, when there are global settings for those? Thanks! BTW, thanks for the great software all of you. Michael, I've come across some of your work, you have my respect!

Accessing Shared Mailbox not working

Hi, I'm new on this mailing list and I'm struggling with the configuration of shared mailboxes. I've followed the following documentation page : https://doc.dovecot.org/configuration_manual/shared_mailboxes/shared_mailbo… and manage to had it working for something like 2 minutes, but then changed a parameter and can't get it back working (and of course I don't remember which one it was).

R: Dovecot 2.3 shared namespace issues
by Stefano Cecconello 15 Nov '22

15 Nov '22

Hello, My bad, the OS was ubuntu 20.04 and not 22.04 . After further tinkering\testing, it seems that removing the " acl_ignore_namespace = shared/* " setting did the trick, now we're getting the correct ACL on client side . Without it we can see the folder with the right permissions : Logging as user01 : shared\Sharer01\INBOX : '[NONEXISTENT] Mailbox doesn't exist: shared/test.imapsharer01(a)td01.testdomain.it/INBOX'' shared\Sharer01\subfolder01 ( RW ) : 'shared/test.imapsharer01(a)td01.testdomain.it/subfolder01 test.imapuser01(a)td01.testdomain.it akxeilprwtscd '] shared\Sharer01\subfolder02ro ( RO ) : '[NOPERM] You lack administrator privileges on this mailbox' Logging on Thunderbird and other IMAP clients ( sylpheed\claws ) as user01 : - It list correctly the shared folders as subscribed folders ; - can't view the mail contents of the sharer INBOX, as desired ; - show the total elements of the sharer INBOX, even if the user01 didnt have access ; If the config is correct, this is somehow what we're trying to accomplish, i have some concerns regarding how it is possible to show the total messages of the remote INBOX without having any privileges . Maybe is something related to the index of that INBOX folder that is somewhat read by the accessing user even if IMAP-wise didnt have any ACL \ rights . I still dont understand why enabling the acl_ignore_namespace setting, results in a : - remote INBOX full control, even if it was not defined in any acl ; - subfolders ACL applied correctly Hope that someone can shed a light on it . Thanks Stefano

Re: bug: ARGON2 hash selection incompatible with LDAP
by Krisztián Szegi 15 Nov '22

15 Nov '22

Sorry, I wanted to post from this alias, but From-Address isn't saved with my drafts :) I failed to recognize during my patchwork that the verification function is the same for ARGON2I and -ID: both call `verify_argon2`, which in turn calls `libsodium's crypto_pwhash_str_verify`. In the new light this, there is no "harm" in my patch: - If backend gives back "{ARGON2}...", dovecot verifies with the same call anyway, regardless of what subtype it actually is, i.e.: {ARGON2I} will work too. - If dovecot generates the hash, the prefix will be the one set by the config's default hash, so for backwards comp., "{ARGON2ID}" could be used if someone wants that. Dovecot will succeed in verifying {ARGON2} generated by itself as well.

Dovecot 2.3 shared namespace issues
by Stefano Cecconello 15 Nov '22

15 Nov '22

Hello, We're trying to configure the shared mailbox feature\namespace on a dovecot 2.3 installation . OS : Ubuntu 22.04 x64 Dovecot : 2:2.3.19.1-2+ubuntu20.04 Our test enviroment is based on a dovecot frontend ( director + proxy ) and a dovecot backend ( auth and storage ), later we will think about increasing the number of backends and frontends ( if we got it right, as we plan to use multiple backends, we should use imapc in order to bind the sharer and the accessing user to the same backend ) . On dovecot backend we've configured the new shared namespace, as stated in the documentation ( https://doc.dovecot.org/configuration_manual/shared_mailboxes/shared_mailbox es/#user-shared-mailboxes ) : -- Dovecot conf -------------------- # Maildir's location is under home dir, which is returned by userdb. mail_location = maildir:~/Maildir:VOLATILEDIR=/tmp_lock/%2.256Nu/%u # Quota, mail_log plugins enabled everywhere mail_plugins = quota notify acl fts fts_lucene mail_log mailbox_alias virtual # Default namespace namespace { hidden = no inbox = yes location = prefix = separator = / type = private mailbox Sent { special_use = \Sent auto = create } mailbox Trash { special_use = \Trash auto = create } mailbox Drafts { special_use = \Drafts auto = create } mailbox SPAM { special_use = \Junk auto = create } } # namespace used by virtual search namespace { prefix = VrtSearch. separator = / location = virtual:/etc/dovecot-common-backend/virtual:INDEX=~/virtual hidden = yes subscriptions = no inbox = no list = no } # IMAP SHARING FEATURE service dict { unix_listener dict { mode = 0600 user = vpopmail group = vchkpw } } plugin { acl = vfile acl_ignore_namespace = shared/* acl_shared_dict = proxy::acl-mysql } dict { acl-mysql = mysql:/etc/dovecot-common-backend/dovecot-dict-sql.conf.ext } # namespace used for IMAP sharing feature namespace { type = shared separator = / prefix = shared/%%u/ location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u list = children subscriptions = no } -- Dovecot dict sql -------------------- # IMAP SHARING FEATURE connect = host=x.x.x.x dbname=xxxxxx user=xxxxxx password=xxxxxx map { pattern = shared/shared-boxes/user/$to/$from table = imap_user_shares value_field = dummy fields { from_user = $from to_user = $to } } map { pattern = shared/shared-boxes/anyone/$from table = imap_anyone_shares value_field = dummy fields { from_user = $from } } -- Dict DB contents -------------------- mysql> select * from imap_user_shares; +------------------------------------------+-------------------------------- --------+-------+ | from_user | to_user | dummy | +------------------------------------------+-------------------------------- --------+-------+ | test.imapsharer01(a)td01.testdomain.it | test.imapuser01(a)td01.testdomain.it | 1 | +------------------------------------------+-------------------------------- --------+-------+ For our tests, we've : - created two users test.imapsharer01(a)td01.testdomain.it test.imapuser01(a)td01.testdomain.it - Created two INBOX subfolders on the sharer01 user, giving user01 those permissions : subfolder01 giving to user01 Full control subfolder02ro giving to user01 list and read - logging as user01 with thunderbird, we see the shared namespace tree : shared test.imapsharer01(a)td01.testdomain.it subfolder01 subfolder02 we're able to see the contents of each folder, even the INBOX . Checking the folder properties, thunderbird reports that the user01 has full control on the INBOX of shared01 .

Questions around mailcrypt and LDAP
by Andre Rodier 15 Nov '22

15 Nov '22

Hello, all. I read carefully the messages about mailcrypt on the mailing list, especially this response from Aki: > It's best suited for securing external storage such as NFS or object storage. > There are possibilities to encrypt the key using user's password, but this > takes careful planning. The keys can also come from userdb , e.g. LDAP. I am able to extend the LDAP schema of my OpenLDAP server to store a key into LDAP attribute for each user. In this case, would it be enough for Dovecot to encrypt the messages when they arrive ? Maybe I misunderstand the documentation. Even when using user keys protected by a password, the Dovecot LMTP process should be able to encrypt the emails with user’s public key, without a password, no ? Ideally, I would like to store user's emails encrypted, so each users cannot access other user's emails. I don't need folder sharing. Thanks for your advice. Kind regards, André Rodier

Dovecot not offering TLSv1.2 after a few minutes
by Markus Wienhöfer 14 Nov '22

14 Nov '22

I have a very strange problem with one of our Dovecot servers (2.2.33.2) on Ubuntu 18.04. The current configuration allows for TLSv1 to TLSv1.3 connections. I can verify those using testssl.sh, the tests will succeed (although correctly mentioning, that TLSv1 and TLSv1.1 should be disabled). Running the tests again after about 5 minutes, the results are different. TLSv1.2 now shows "not offered and downgraded to a weaker protocol". Has anybody experienced a similar problem before? Best regards Markus

Dovecot 2.3.19.1: BUG: Mailbox renaming algorithm got into a potentially infinite loop, aborting
by Ralf Becker 14 Nov '22

14 Nov '22

I found this from 2019 on the list: https://www.mail-archive.com/dovecot@dovecot.org/msg78898.html Timo mentioned it's tracked internally as DOP-1501, but I could find nothing about it being fixed on the (public) list. Any news about that and is the workaround of deleting dovecot.mailbox.log* and dovecot.list.index* still the recommendation, when running into this bug.

Submission: track authenticated_user
by itanguy＠univ-brest.fr 10 Nov '22

10 Nov '22

Hello, We would like to use Dovecot Submission to have less queues to maintain. The relayhost (Postfix) after Dovecot routes mail by sender_map, so authenticated user, not the "mail from" because . For what we've seen, we can't use receive header to retrieve this authenticated_user. Example of header : Received: from mailhost ([0.0.0.0]) by submission.host with ESMTPSA id submission-id (envelope-from<myadress(a)example.com>) for<myadress(a)example.com>; Thu, 9 Nov 2022 08:27:41 +0000 So we've thought to use X-client, but reading the doc seems that's not the a good way : /https://doc.dovecot.org/settings/core// - submission_relay_trusted If enabled, the relay server is trusted. Determines whether we try to send (Postfix-specific) XCLIENT data to the relay server (only if enabled). But, XCLIENT for Submission seems to not transfer LOGIN : /https://doc.dovecot.org/settings/core/ / XCLIENT command can be used to override: Session ID Client IP and port (|%{rip}|,|%{rport}|) HELO - Overrides what the client sent earlier in the EHLO command LOGIN - Currently unused PROTO - Currently unused |forward_*| fields can be sent to auth process’s passdb lookup The trust is always checked against the connecting IP address. Except if HAProxy is used, then the original client IP address is used. Do you know another way to inform the relayhost of submission of the authenticated_user? Thanks Ismaël TANGUY

Help with configuration?
by Ellie McNeill 10 Nov '22

10 Nov '22

Hi, I'm running my own mail server on Debian 11 with exim and Dovecot 2.3.13. I have it working, but I'm seeking advice on further customising my setup. I'm using the Maildir++ format with some personal folders. I use IMAP to retrieve mail and Dovecot's submission server to send mail. 1. I want to have incoming emails automatically placed in certain folders instead of 'Inbox' based on certain criteria. For example, I want all emails from PayPal to go into the 'PayPal' folder and all emails from the Debian mailing list to go into the 'Debian' folder. Can dovecot do this for me and what is the best approach? 2. When I delete an email using my user client, it is only 'marked' as deleted (Thunderbird places a scored line through it, and a 'T' is added to the filename in the Maildir). How can I get dovecot to automatically move mail marked 'deleted' to the Trash folder each time? I also want further delete operations on any mail in the 'Trash' folder to be permanently deleted. 3. I want to hide my client IP address from the headers when submitting mail to Dovecot's submissiond, but I can't seem to find any way to disable this. I would prefer that recipients only see the server IP address, but not the IP address of the mail client which submitted it. Regards, Ellie PS - When signing up for the mailing list, there was no selection ability on the question "Would you like to get replies to your mails only to the list, ie. add a Reply-To header?"

Someone has probably already replied to this, but it's a typo: the OP wanted to say "store". The certificate you created was used to sign itself ("self signed") and thus, asserts its own validity. If you need *other* people to trust your SSL service, you should sign your certificate using a third party authority (e.g. LetsEncrypt) to sign it. Most internet users will have these third party signing authority's certificates in their certificate store to validate your service certificate. If this is for your own personal use (i.e. you don't care about trust since you know it's your own certificate), you have to add your self-signed certificate into *your* system's certificate authority store so that your mail reader does not complain about an untrusted certificate. Clear? Joseph Tam <jtam.home(a)gmail.com>

doveadm backup|sync works for every folder but INBOX

09 Nov '22

I'm trying to migrate an old Cyrus 2.5 server to Dovecot 2.3.19 using doveadm backup -R, which works for all folders but the INBOX itself, which always stays empty. The Cyrus side uses altnamespace:no and unixhierarchysep:no, it's used as imapc: remote in doveadm backup -R with imapc_list_prefix=INBOX Dovecot uses the following namespace to migrate into: namespace inboxes { inbox = yes location = mailbox Sent { auto = subscribe special_use = \Sent } ### some more folders omitted ### prefix = INBOX/ separator = / subscriptions = no } I use the following command line for the migration: doveadm -o imapc_features='rfc822.size fetch-headers' -o mail_prefetch_count=20 -o namespace/subs/location=mbox:/var/dovecot/subs -o imapc_user='someuser' -o imapc_password='secret' -o imapc_host=<cyrus-ip> -o imapc_list_prefix=INBOX -D backup -f -n INBOX/ -R -u someuser@somedomain imapc: The debug output contains the following lines: Nov 02 10:16:01 dsync(someuser@somedomain): Debug: brain S: Namespace INBOX/ has location imapc: Nov 02 10:16:01 dsync(someuser@somedomain): Debug: brain M: Local mailbox tree: INBOX guid=d8d5a3122bce5f63ef9101001ebfc848 uid_validity=1667223083 uid_next=1 subs=no last_change=0 last_subs=0 Nov 02 10:16:01 dsync(someuser@somedomain): Debug: brain S: Local mailbox tree: INBOX guid=c92f64f79f0d1ed01e6d5b314f04886c uid_validity=1577952633 uid_next=32691 subs=no last_change=0 last_subs=0 Nov 02 10:16:28 dsync(someuser@somedomain): Warning: Mailbox changes caused a desync.

In a tcpdump of the IMAP trafic I can see a STATUS "INBOX" (UIDNEXT UIDVALIDITY) but no EXAMINE "INBOX" or something else I would expect from the sync. I can provide the full output of doveadm backup/sync and a pcap of the IMAP trafic, but not to the public list. Any idea what's wrong with the sync of the INBOX or other suggestions / imapc parameters to use?

"Mailbox isn't a valid MBOX file" Error
by Elise 06 Nov '22

06 Nov '22

Running currently two local mailclients: Outlook 2021 and Thunderbird 102.4.2 When using TB and remove a message on my main account, I get this error: [CANNOT] Mailbox isn't a valid mailbox On any other TB configured email accounts I can remove messages without any problems. First I thought that Outlook might block removal on messages, but the issue appears as well if I close that mail client. Can you tell what is causing this problem? Best regards, Jos Chrispijn

Any update on lazy load SNI?
by Pierre Allétru 03 Nov '22

03 Nov '22

Hi folks, We need to use SNI with Dovecot at a relatively large scale and I was wondering if there's any update on the ability to: 1 - Lazy load SNI certificates when they are needed instead of loading them all at once during startup/reload, thus taking a lot of memory and being very slow. 2 - Not having to reload Dovecot every time a new domain cert is added in conf. 3 - Or at least have Dovecot keep processing clients while the slow reload happens. This has been asked already in a 2016 thread: https://www.dovecot.org/pipermail/dovecot/2016-November/106075.html. Regarding point 3 there's a reply from Aki saying it was in the internal tasklist ( https://www.dovecot.org/pipermail/dovecot/2016-November/106089.html) Anybody knows if some progress has been made on these subjects? I can't anything in the docs or any recent information anywhere else. Thanks, -- Pierre Allétru 06 70 55 08 35 pierre.alletru(a)gmail.com

I recently stumbled upon the following commit on the Dovecot core Github repository: https://github.com/dovecot/core/commit/4a187116dc2311804be22724007d35732300… Apparently, Dovecot Director is going to be removed in the next major version of Dovecot and the commercial Dovecot cluster architecture will be its successor: https://github.com/dovecot/documentation/blob/a85b742ec4fc2744db30a6943b3c2… This would be a huge blow for many organizations around the world that are currently using Dovecot with Director in a shared storage environment. Can anyone of the Dovecot developers maybe enlighten us about the future of Dovecot? - Will there still be the Director feature in the next community release of Dovecot? - If not, will there be a community feature that is on par with the current Director feature? - For how long will Dovecot version 2.3 still be supported (security fixes, bug fixes)? Is there any EOL plan? Thanks for any clarification! Steff
