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).

bug: ARGON2 hash selection incompatible with LDAP
by Krisztián Szegi 25 Nov '22

25 Nov '22

Good day to all, this is my first post to the mailing list! I'd like to report that non-binding auth to (Open)LDAP doesn't work if the latter hashes passwords with ARGON2. Although dovecot (I am using http://2.3.19.1) does support ARGON2 with libsodium, but it doesn't recoginize hashes beginning "{ARGON2}$argon2id$" stored (and hashed, using ppolicy module's hashCleartext) by OpenLDAP. Now, I understand that ARGON2I, -D, and -ID are not compatible, but the ACTUAL algorithm is there between the two $. Furthermore, I think dovecot is in the minority here, I haven't met any software that specifies the ARGON2 subtype between {}. BTW, I haven't met any software that hashes passwords with ARGON2, but not with the ARGON2ID subtype (where libsodium is available, which also seems to be the standard here), as THAT is the recommended one anyway. I patched the rpm in OpenSUSE repo to alias {ARGON2} to {ARGON2ID}: https://build.opensuse.org/package/view_file/home:Samonitari:branches:openS… Could we get something like this (but maybe more correct) into the official source? Maybe a config switch to alias it runtime? Thanks for the attention: Krisztián

compiled sieve files svbin ?
by jeremy ardley 23 Nov '22

23 Nov '22

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

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 . If we try to check the ACL via python script ( imaplib.gestacl ) or via doveadm, we can see that the sharer01 INBOX has no rights for user01 . But via thunderbird ( or other email clients ) we can delete emails . ACL - sharer01 accessing its folder ('OK', [b'INBOX test.imapsharer01(a)td01.testdomain.it lrwstipekxacd']) ('OK', [b'subfolder01 test.imapuser01(a)td01.testdomain.it akxeilprwtscd test.imapsharer01(a)td01.testdomain.it lrwstipekxacd']) ('OK', [b'subfolder02ro test.imapuser01(a)td01.testdomain.it lr test.imapsharer01(a)td01.testdomain.it lrwstipekxacd']) ACL - user01 accessing sharer01 folders ('OK', [b'shared/test.imapsharer01(a)td01.testdomain.it/INBOX']) ('OK', [b'shared/test.imapsharer01(a)td01.testdomain.it/subfolder01 test.imapuser01(a)td01.testdomain.it akxeilprwtscd']) ('OK', [b'shared/test.imapsharer01(a)td01.testdomain.it/subfolder02ro test.imapuser01(a)td01.testdomain.it lr']) Testing with doveadm shows the correct ACL : #

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
by Ralf Becker 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

The end of Dovecot Director?
by Steff Majeur 02 Nov '22

02 Nov '22

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

Dovecot does not start on MacOS Monterey
by Doro Rose 30 Oct '22

30 Oct '22

Hi, this is a duplicate of the "Dovecot does not start on MacOS Monterey 12.01" thread. I’m still seeing this on dovecot 2.3.19.1. Is there a recommended workaround? The last post in that thread indicated that some modifications in `./src/lib/restrict-process-size.c` might be necessary. Best regards Doro

Mailing list IMAP archive.

I am trying to use the IMAP mailing list archive described on https://www.dovecot.org/mailing-lists/ Is this feature still functioning? Using Thunderbird i get an error message that the connection was refused. I don't know if Thunderbird isn't functioning properly (with handling no password) or if the service is down. My end goal is i want to search the archive for solutions before asking the list. Is there a browser based option to search the archives? I didn't see a search option on https://dovecot.org/pipermail/dovecot/

Should be much easier to build a project doing this than forking director. This is my train of thought as well. I believe the following would suffice for most setups. A database with: - Current vhost count per backend server. Alternatively, count the temporary user mappings. - Backend servers. - Temporary user mappings between user - backend server. This database is accessible by all Dovecot proxies in case there’s multiple. Steps when receiving a login: - Check if a temporary user mapping exists. - If so, proxy to the backend server in the temporary mapping. (To do: clean up mappings.) - If not, pick the backend server with the lowest vhost count, create a temporary mapping, then increase the vhost count of the chosen backend server. A monitoring service up/downs backend servers. E.g. by checking the port that we proxy to for each backend server. When a backend server is set to down, kick the user to force a reconnection. (Is that how Director ‘moves’ users?)

Catch all for Metadata storage in SQL database
by Steffen Kaiser 27 Oct '22

27 Oct '22

Hi, the https://doc.dovecot.org/configuration_manual/imap_metadata/ sample uses mail_attribute_dict = file:%h/Maildir/dovecot-attributes which stores all keys=value pairs in the file. http://dovecot.2317879.n4.nabble.com/Dovecot-v2-3-9-3-HTTP-API-Endpoint-for… uses a SQL dict, however very specific ones. How can I use a SQL dict to store _all_ keys, as with a file based storage? I cannot find a documentation for "pattern" specification, that works as "catch all", in order to store anything not catched by patterns into the database. https://wiki.dovecot.org/Dictionary does not give any hint (in my eyes). -- Steffen Kaiser

Dynamically set LDAP user namespace using two attributes

Hi, I’m looking for a way to use two LDAP attributes to create a user-specific namespace to be expunged e.g. mailExpungeTrash=namespace/inbox/mailbox/%{ldap:mailTrashMailbox}/autoexpunge I can create the namespace fine returning the full string to be expunged: mailExpungeTrash=namespace/inbox/mailbox/Deleted\_Messages/autoexpunge However I want to alter the namespace using a second LDAP attribute like: mailExpungeTrash=namespace/inbox/mailbox/%{ldap:mailTrashMailbox}/autoexpunge Regards Thomas

The session commands-repliesd is is more or less what I expect, although to make sense of this, you'll have to splice the input and output files together using timestamps to see the sequential flow of data. I forget what the symptoms you originally reported, but theoretically, you could simulate either client or server by feeding in the above data and see how the other end behaves. If dovecot is serving out the correct data, then TB is somehow misinterpreting it. > on an uneducated guess, the mailbox is just 'too large' ? > POP has difficulty handling so many files ? Typically, if some resource limit is hit, one side or the other will create a log or notification. Your INBOX is large, but not outrageous. You can test it directly by creating smaller subsets of the INBOX messages and see if the problem goes away. Joseph Tam <jtam.home(a)gmail.com>

Office 365 SSL issue
by Ervin Hegedüs 23 Oct '22

23 Oct '22

Hi there, I have a bit old Dovecot instance (Ubuntu 14.04 - there is no chance to upgrade it), with these versions of packages: * Dovecot: 2.2.9 * OpenSSL: 1.0.1f Few days ago a client noticed me, that he can't reach his mails through his Office 365. He uses POP3S. I tried to set up a same client for this Dovecot server, but when I configured the POP3 protocoll, after the settings check Office says: Your server does not support the connection encryption type you have specified. Try changing the encryption method. Contact your mail server ... While the client was trying, I see these lines in the log: Oct 21 16:12:18 mail dovecot: pop3-login: Debug: SSL: where=0x10, ret=1: before/accept initialization [192.168.8.133] Oct 21 16:12:18 mail dovecot: pop3-login: Debug: SSL: where=0x2001, ret=1: before/accept initialization [192.168.8.133] Oct 21 16:12:18 mail dovecot: pop3-login: Debug: SSL: where=0x2001, ret=1: SSLv3 read client hello A [192.168.8.133] Oct 21 16:12:18 mail dovecot: pop3-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write server hello A [192.168.8.133] Oct 21 16:12:18 mail dovecot: pop3-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write certificate A [192.168.8.133] Oct 21 16:12:18 mail dovecot: pop3-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write key exchange A [192.168.8.133] Oct 21 16:12:18 mail dovecot: pop3-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write server done A [192.168.8.133] Oct 21 16:12:18 mail dovecot: pop3-login: Debug: SSL: where=0x2001, ret=1: SSLv3 flush data [192.168.8.133] Oct 21 16:12:18 mail dovecot: pop3-login: Debug: SSL: where=0x2002, ret=-1: SSLv3 read client certificate A [192.168.8.133] Oct 21 16:12:18 mail dovecot: pop3-login: Debug: SSL: where=0x2002, ret=-1: SSLv3 read client certificate A [192.168.8.133] Oct 21 16:12:18 mail dovecot: pop3-login: Warning: SSL failed: where=0x2002: SSLv3 read client certificate A [192.168.8.133] Oct 21 16:12:18 mail dovecot: pop3-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=192.168.8.133, lip=192.168.8.21, TLS handshaking: Disconnected, session=<9sWMB4zr+ADAqAiF> Which is weird, because I disabled SSLv3.

Change password schema and post-login script
by Christos Chatzaras 23 Oct '22

Hello, Question #1: For version 2.3.19.1 these commands use BLF-CRYPT, right? doveadm pw doveadm pw -s CRYPT Question #2: I want to change password schema for current users. For users using POP3 or IMAP I can do it using a post-login script. I have some accounts used only to send e-mails using Postfix, so no POP3/IMAP logins for these accounts.

dovecot mailing list (this mailing list), DKIM, SPF and DMARC
by Lev Serebryakov 22 Oct '22

22 Oct '22

My domain (serebrtyajov.spb.ru) has all these "new" e-mail technologies configured. It works fine till I write to this mailing list. After that I've got several DMARC reports about "spam" from my domain. All these reports are about my mailing list post. I don't have such problems with other mailing lists (FreeBSD ones, OpenJDK ones, and others). Looks like mailing list software for this mailing list is misconfigured. I'm sure, I'll get new after this message. -- // Black Lion AKA Lev Serebryakov

lmtp userdb can't resolve users
by George Asenov 21 Oct '22

21 Oct '22

Hello, I use postfix with dovecot as an lmtp LDA with unix users and multiple domain names and mailboxes in Maildir format placed in domain directory like: /home/mainuser/homes/user(a)domain.tld/Maildir or /home/mainuser/domains/domain2.tld/homes/user(a)domain2.tld/Maildir which have the main user as a group and user@domain.tld/user@domain2.tld as owner Postfix have virtual_alias_maps = hash:/etc/postfix/virtual there in virtual file there is map like: user(a)domain.tld user-domain(a)domain.tld and in /etc/passwd there are actually 2 users with the same home dir and same UID/GID (only the username is different) and in postfix mailbox_transport = lmtp:unix:private/dovecot-lmtp The issue is that when postfix passes the email for local delivery to dovecot lmtp it sends the username as user-domain.tld(a)serverhostname.tld but dovecot is configured with !include auth-system.conf.ext can't resolve this username thus fails to deliver. I've found a workaround in the net to use custom userdb just for lmtp like this: protocol lmtp { mail_plugins = $mail_plugins sieve userdb { driver = passwd-file args = username_format=%n /etc/passwd } } which works but produce some warnings because there is the root user (ID 0) and actually is a dirty workaround Is there more elegant solution??

In what section of the config is this limited? I assume it is related to this >go1.13 memory model that allocates quite a lot of vsz?

mdbox vs. maildir format
by Michael 19 Oct '22

19 Oct '22

hey, i am considering changing my mailbox format from maildir to mdbox. the reason for this is mainly, b/c i have (a) multiple large mailboxes with tens of thousands of mail files, and (b) most of these mails files have a size significantly smaller than the sector size of the disk. so, since the emails themselves are only about nGB large, the disk space used is at least twice as much, if not even three times. i know, hard disk space is 'cheap', but still... but then i read at https://doc.dovecot.org/admin_manual/mailbox_formats/dbox/ the following: [...] you must not lose the dbox index files, as they can’t be regenerated without data loss. so, raid is mandatory, which is already the case, but what about backup? how can i achieve a backup/snapshot of both, the mdbox (nfs share) and the index files (local raid) and assure they are consistent? greetings...

Unseen field reported by imap status command returns wrong count for shared mailboxes on dovecot cluster
by Nikolaos Pyrgiotis 19 Oct '22

19 Oct '22

Hello, We recently migrated our mail server to a dovecot cluster of 5nodes, a dovecot proxy, 2directors and 2dovecot backends. All dovecot nodes run version 2.19.1. We use a glusterfs mounted volume on the backends forthe mail storage. We noticed that when issuing the IMAP command to check forUNSEEN messages formails on the shared namespace instead of seeing the value of the unseen messages of the user that the mailbox has been shared to, the value of the unseen messages of the owner of the mailbox is returned. This behavior causes thunderbird when getting new messages forshared mailboxes, to show briefly all messages of the mailbox as unseen forthe user before showing the correct unseen count forthe shared mailbox. The mail location of the shared mailboxes is defined with imapc storage type as described inthe documentation. Is this a dovecot bug? Can we configure a different dovecot configuration setting so that imap status command reports the correct unseen field count when mail location is an imapc storage location? An examples is given below when running doveadm command from one the 2 dovecot directors: When issuing the status command we see that the unseen count is 2: root@doved0-rmt0-cn1:/etc/cron.d# doveadm mailbox status -u npyrgiotis all shared.sysadmins doveadm(npyrgiotis): Info: remote(10.101.0.71:8080): doveadm(npyrgiotis(a)domie02.com)<19078><9l8IJTb+GWOGSgAAEU9A+w>: imapc(10.101.0.75:143): Connected to 10.101.0.75:143 (local 10.101.0.71:33476) shared.sysadmins messages=2 recent=0 uidnext=3 uidvalidity=1662640492 unseen=2 highestmodseq=3 vsize=3950 guid=c92f64f79f0d1ed01e6d5b314f04886c firstsaved=1662643853 shared.sysadmins messages=2recent=0uidnext=3uidvalidity=1662640492unseen=2highestmodseq=3vsize=3950guid=c92f64f79f0d1ed01e6d5b314f04886c firstsaved=1662643853 But when fetching the emails of the mailboxes we can see that the \Seen flag is set for both emails root@doved0-rmt0-cn1:/etc/cron.d# doveadm fetch -u npyrgiotis flags mailbox shared.sysadmins ALL doveadm(npyrgiotis): Info: remote(10.101.0.71:8080): doveadm(npyrgiotis(a)domie02.com)<19074><e7rWDgj+GWOCSgAAEU9A+w>: imapc(10.101.0.75:143): Connected to 10.101.0.75:143 (local 10.101.0.71:38750) flags: \Seen flags: \Seen Below i post the dovecot configuration of one of the two dovecot backends: #

by Serveria Support 18 Oct '22

18 Oct '22

I'm trying to setup Dovecot with mail-crypt plugin with per-user encryption. I have configured mail-crypt plugin as per official guide here: https://doc.dovecot.org/configuration_manual/mail_crypt_plugin/ After that I created a user and an encrypted key by running this command: doveadm -o \plugin/mail_crypt_private_password=12345 mailbox cryptokey generate -u mail(a)example.org -URf (replacing dummy data ofc) I can log in to webmail (and Dovecot) just fine, emails are getting sent and delivered. I have also checked the storage and the messages seem to be stored encrypted. However, I can't read the emails in webmail (just headers can be seen) and in Dovecot logs I can see the following error: failed: Private key not available: Cannot decrypt key ### Cannot decrypt key ### <8632: Password not available (FETCH RFC822.HEADER) There seems to be an issue with mySQL query. The query I'm using (Select username as "user", password,"%w" as userdb_mail_crypt_private_password from mailbox;) seems to work just fine, when run from mysql prompt it outputs the usernames and passwords, but the error is still there (Cannot decrypt key ### Password not available). Any ideas? What am I missing?

sieve script not modifying header
by Marc 17 Oct '22

17 Oct '22

From the command line the sieve script is modifying the header like this: su testuser -s '/bin/bash' -c 'cat test.msg | /usr/lib64/dovecot/sieve-execute/sieve-test' However when executing via dovecot, the header stays unchanged require ["copy","fileinto","vacation","vnd.dovecot.execute","editheader"]; # rule:[testing2] if not execute :pipe "sieve-test" { } Any idea what I am forgetting to configure/allow?

adding caldav/carddav next to dovecot
by Marc 16 Oct '22

16 Oct '22

I hope it is ok to post this off-topic question here. I was wondering if there are here environments running that offer next to dovecot also calendar and contacts services. In the past I was testing a bit with the one from Apple, but I think it is being discontinued because of converting the python 2 code. I am looking for some experience with a setup provisioning >10k users. Not that I have such requirement, but I want to know if the solution is stable, efficient and optionally can scale. I need something efficient, because I do not have to many resources and high iops available. I also do not want any other other 'crap' just the cal (and card) dav solution. https://github.com/1and1/cosmo This looks interesting (used 1und1 in Germany?) but not big community https://sabre.io/dav/install/ This is in php ...

Re: ot: how to t/s TBird problems ?

I suspect you'll need to do session logging e.g. protocol pop3 { ... rawlog_dir = /writable/logdir/%u } then mkdir /writable/logdir/user chmod 0777 /writable/logdir/user to obtain session transcripts of what server/client are doing. I don't see any obvious errors from the logs that indicate any failure. I do see the INBOX is rather large so maybe a timeout is involved. Joseph Tam <jtam.home(a)gmail.com>

Re: LDAP just for passdb
by Francis Augusto Medeiros-Logeay 14 Oct '22

14 Oct '22

Again, a bit more reading got me to adding this to my passdb config: username_filter = *(a)domain-a.com This way, I can control which domains get to authenticate via my ldap backend, which gives me time to design a good way of saving other attributes there. If anyone have other ways of doing this, ie., having multiple domains on ldap/freeipa and getting an elegant integration with Dovecot, I’d be glad to hear.

Re: LDAP just for passdb
by Francis Augusto Medeiros-Logeay 14 Oct '22

I actually saw that it was possible, and it works, but I came across another problem and I wonder if you have any tips about it: On my current dovecot setup, I use SQL as the backend. So I have the following users: francis(a)domain-a.com <mailto:francis@domaina.com> francis(a)domain-b.com <mailto:francis@domain-b.com> Those are separate users which their own mailboxes. However, I have a freeipa that is configured for the `domain-a.com <http://domain-a.com/>` realm. However, since I am using `%n` for the uid search: auth_bind_userdn = uid=%n,cn=users,cn=accounts,dc=domain-a,dc=com And pass_filter = (&(objectClass=posixAccount)(uid=%n)) It of course leads up to both users above being able to authenticate with the same password. Is there a way to limit ldap authentication to just one domain, or perform a search where both username and domain are checked? I could use the `mail``attribute to filter users, but I imagine that if two users have the same mail configured, I’d run into trouble….

LDAP just for passdb
by Francis Augusto Medeiros-Logeay 14 Oct '22

14 Oct '22

Hi, I couldn't find it in the documentation, so I was wondering - is it possible to configure Dovecot to use LDAP for passdb and keep using SQL for userdb? I would like to do that before I come up with a good strategy to expand my ldap schema to support other mail attributes for virtual domains, aliases, etc. I am currently using FreeIPA. Best, Francis

"make check" fail at test_program_refused
by A. Schulze 14 Oct '22

14 Oct '22

Hello, I moved my buildsystem to an other platform (I do not fully control) and now receive this error on "make check" Error: program tcp:127.0.0.2:42027: connect(::1) failed: Connection refused test_program_refused ................................................. : FAILED The build run on jenkins buildnodex spawn up on a kubernetes cluster. What I noticed so far: the buildnode opereate ipv4 only but has an entry in /etc/hosts: 127.0.0.1 c4a84c76f0d6 ::1 c4a84c76f0d6 Maybe that's the glitch ... I tried dovecot-2.3.15 and 2.3.19.1. Both fail (only the portnumber differ) Is there an option to disable only one specific test? I dislike to skip "make check" at all. Andreas

what are the options to 'interact' with a dovecot imap user
by Marc 14 Oct '22

14 Oct '22

I am looking for a user friendly way to have a user to tell the 'server' to either store or remove an email address. a. My first thought was to use imapsieve for this and have an imap sieve plugin store/remove the email address of the message that is being dragged into a predefined monitored folder. This would work with any imap client b. I was thinking about the message Flagged[1]. I am curious how would I be able to detect this (in sieve)? This does not seem to be stored in the source of the message. Although every client seems to support it, it would probably conflict with every day use cases. c. Then you have these colours and/or categories. But these do not seem to propagate across clients. Where are these even stored? Any ideas on how this can be done?

Director hashing
by Dan Conway 14 Oct '22

14 Oct '22

Hello all, I have a 2 node director setup that uses checkpassword for authentication as well as backend assignment through director tags. director_servers = 192.168.1.10 192.168.1.20 director_mail_servers = 192.168.2.10@srv1 192.168.2.11@srv2 checkpassword writes the following to Dovecot on successful authentication: proxy=y\tdirector_tag=<tag>\tport=<port>ssl=yes\tdestuser=<email>\t This seems to work just fine. However, when I attempt to view a users current hash/initial config: # doveadm director status "user(a)domain.com" Current: n/a (expires -1) Hashed: Initial config: I get null data. There does appear to be a hash mapping of some sort however: # doveadm director map -u user(a)domain.com 1140334690 # doveadm director map -h 1140334690 user(a)domain.com The use of doveadm director move has no effect. doveadm reports it moved the user, but it does not: # doveadm -v director move "user(a)domain.com" 192.168.2.11 Info: User hash 1140334690 moved to 192.168.2.11 When using checkpassword and supplying fields to Dovecot, should I also be including another field to populate hashes for director? I could be missing something obvious in the docs. I'm on version 2.3.18 (9dd8408c18). I have not included dovecot.conf due to the size. If someone needs to see it I can supply it.

keep in mind that the cert purchased is only for the name : mail.paulkudla.net thus i fail to see why it is throwing error 42, however this seems to be a patch to thunderbird as well i did not have to

One-off backup
by Ian Evans 11 Oct '22

11 Oct '22

I run a small email server for me and the missus. Six dovecot users. Our host is migrating our server instance. They usually (99.9999% lol) go off without a hitch. As we don't have dovecot running elsewhere, I'm assuming doveadm is the wrong tool. If we want to make a one-off backup prior to the migration, is shutting down postfix and running tar czf mailstorage.tgz /path/to/mail okay? Thanks.

Static build problems
by Jacob Welsh 09 Oct '22

09 Oct '22

I'm attempting to build the latest Dovecot, version 2.3.19.1, on Gales Linux, a distribution based on musl libc with all static linking. After working around some expected troubles to generate configure, such as the libtool and iconv.m4 dependencies, the build appeared to complete successfully. But on closer inspection, the plugins were installed as a bunch of .a and .la files rather than getting linked into any of the binaries, as would be necessary to actually use them. I determined that the probe for dynamic module support (DOVECOT_MODULES defined in 'm4/modules.m4') had returned a false positive: in the static configuration musl includes a stub dlopen() that always returns failure at runtime, so a compile-and-link-only test is not predictive. Libtool itself is affected in the same way, but it comes with the --disable-shared option which usually makes things works fine. Short of a proper solution (perhaps removing modules.m4 and going instead by what libtool already determined, since you've decided to depend on it anyway), I stubbed out modules.m4 to simply return the correct result for this platform, thus: AC_DEFUN([DOVECOT_MODULES], [ have_modules=no AC_SUBST(MODULE_LIBS) AC_SUBST(DLLIB) ]) Now the build is failing due to the absence of a function that's defined only when HAVE_MODULES is true: libtool: link: gcc -I../../src/lib -I../../src/lib-test -I../../src/lib-ssl-iostream -DDCRYPT_MODULE_DIR=\"/gales/pkg/dovecot-0.0-2.3.19.1/lib/dovecot\" -DDCRYPT_SRC_DIR=\"../../src/lib-dcrypt\" -std=gnu99 -g -O1 -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -fno-builtin-strftime -Wstrict-aliasing=2 -Wl,--whole-archive -Wl,../lib-ssl-iostream/.libs/libssl_iostream.a -Wl,--no-whole-archive -o test-stream test_stream-dcrypt.o test_stream-istream-decrypt.o test_stream-ostream-encrypt.o test_stream-test-stream.o ../lib-ssl-iostream/.libs/libssl_iostream.a ../lib-test/.libs/libtest.a ../lib/.libs/liblib.a test_crypto-dcrypt.o: In function `dcrypt_initialize': /home/user/gales-linux/gports/dovecot/build/dovecot-2.3.19.1/src/lib-dcrypt/dcrypt.c:34: undefined reference to `module_dir_try_load_missing' collect2: error: ld returned 1 exit status make[3]: *** [Makefile:664: test-crypto] Error 1 I noticed commit d21897832a443d139d56b1fb1c86d8f76e5f77f3 from 2009, "Fixed compiling without module support", and clearly it's supposed to work since the #ifdefs are there, but I begin to suspect that nobody's actually tested this branch of the configuration tree recently. Further, looking through the automakefiles I'm not finding how the plugin libraries are supposed to work at all in this case and I begin to fear that they simply... aren't. Say it ain't so? Jacob

imapsieve removeflag ignored
by Slavko 08 Oct '22

08 Oct '22

Hi, i have working SPAM reporting implementend by imapsieve in debian's 2.3.13 dovecot. Recently i decide to add personal spam filter by bogofilter and use logic to learn/unlearn SPAM/HAM based on message flags. Here is example of moving message from Junk folder (the opossite logic is similar): if hasflag "$Junk" { execute :pipe "bogofilter" ["-Sn"]; removeflag "$Junk"; debug_log "Learned HAM (and unlearned)"; } else { execute :pipe "bogofilter" ["-n"]; debug_log "Learned HAM (only)"; } # mark as learned addflag "$NotJunk"; report ... When i move message, the debug lines in log shows, that logic works and flag is added as expected, but the other flag is not removed. Thus after moving mail from Junk, which has $Junk flag, it has both flags, the $Junk and $NotJunk. I tried to move removeflag action outside of condition and add it just before addflag, but the result is the same. For now i do not know if here is something wrong in my script, or i did some other mistake. On IRC cmouse tell, that removeflag was fixed in some early version (2.3.5 or so), but it doesn't work here. Please, how i can get it working? regards PS: please CC me, i am not subscribed -- Slavko https://www.slavino.sk/

I think this page[1] is not correct If you configure this option: imapsieve_mailbox1_before = file:/usr/lib/dovecot/sieve/report-spam.sieve the file report-spam.svbin cannot be created because users cannot write there.

Using sqlite as dict for last_auth plugin
by Oleg petol 04 Oct '22

04 Oct '22

Hi! It is required to collect statistics about the time of the last IMAP and POP3 login of the user and the delivery of letters to him via lmtp. The last-login plugin is perfect. But I don't want to use heavy databases as the mail system service is served by the Oracle DB. The most suitable option, as I see, is to store statistics in the sqlite DB, but after going through all the options in the configuration file, I could not use sqlite. When writing in configuration: plugin { driver=sqlite last_login_dict = sqlite:statsdb last_login_key = last-login/%s/%u/%r last_login_precision = ms } I am getting an error: Oct 4 17:01:41 nms4 dovecot: imap(new_ver_test(a)test2.aroma.ru)<154597><q0VJ5jXq9o4KAQDI>: Error: last_login_dict: dict_init(sqlite:statsdb) failed: Unknown dict module: sqlite I did the last-login plugin setup exactly according to the instructions: https://doc.dovecot.org/configuration_manual/mail_location/obox/last_login_… I am using standard debian packages. Desperate, I built latest dovecot version from source, but got exactly the same error. Tell me, please, is it possible to use a dictionary in sqlite format to collect last-login plugin statistics? And how should I describe it in the configuration file?

Good Morning Michael, No problem. Although, to be clear I didnt point out anything, but its Sébastien and the credit shall go for him. Also, by the way in EXIM MTA, there is verify syntax condition in data acl, which checks all email headers and validate that they are standards compliant and reject sending any email beforehand to your issue which has non-compliant header and offers the ability to remove such headers with condition handling e.g. if contained any Sieve header, to request removing message id headers with headers_remove and add compliant one with add_header, and I guess this will mitigate any mail service provider rejection issue. If you are postfix user and considering switching, let me know, I might be able to help. Zakaria.

Matching Addresses in Sieve
by Doug Hardie 01 Oct '22

01 Oct '22

I have an email with the following header line: From: 'Thank you!Kohls' <Kohls-MNc(a)FeedbackKohlsOpinionRequestedlxecrftHO.com> I am trying to match that with: if address :contains "from" "Thank you!Kohls" { addflag "\\Seen"; fileinto "Junk"; stop; } However, the matching portion of the from address is only the section between < and >. Since there are changing sections that are different for each email, I can't use that. I wanted to match the stuff before <. I have tried numerous formats for the if statement but none of them have worked. What is the proper way to make that match work? Thanks, -- Doug

new feature: sieve forward plugin
by Marc 26 Sep '22

26 Sep '22

As this page[1] describes a more often occurring problem of forwarding messages from servers that are not included in the spf records. Maybe there should be a plugin that offers this forward functionality. Something like get the spf records of the sender check if there is a -all then apply the sender substitution. https://doc.dovecot.org/configuration_manual/sieve/configuring_auto_forward…

Custom post login scripting variables via ID command
by hi＠zakaria.website 26 Sep '22

26 Sep '22

Hi there, I wonder if dovecot would consider this feature request. In post login scripting, given USER, IP, LOCAL_IP, and userdb lookup fields, are only available, I want to push additional variables from web mail to dovecot using ID commands yet I looked at the source in imap-login-cmd-id.c and script-login.c it seems to be possible while I'm not an expert in C and IMAP standards and not sure if its something would break the standards. I hope the dev team to consider this and if anyone have a workaround or an idea with I can start to patch a workaround myself, please let me know as it would be very much appreciated. With thanks. Zakaria.

what sieve variables / syntax is available to sieve scripts.
by Marc 25 Sep '22

25 Sep '22

1. where can I find all variables like "imap.user" like in mentioned on page[2] 2. I have the impression that variables like "${from}" are all being set from scanning the whole email again seeing these "if matches" statements. Is that not super inefficient? I would assume that such variables would be set and made available upon the receipt of a message. 3. What is the point of this: if environment :matches "imap.user" "*" { set "username" "${1}"; } pipe :copy "sa-learn-ham.sh" [ "${username}" ]; Why can't I just use: pipe :copy "sa-learn-ham.sh" [ "imap.user" ]; [1] require [ "vnd.dovecot.pipe", "copy", "variables" ]; if header :matches "subject" "*" { set "subject" "${1}"; } if header :matches "from" "*" { set "from" "${1}"; } pipe :args [ "USER(a)DOMAIN.TLD", "${from}", "${subject}" ] :copy :try "jabber_notify.sh" ; from page https://wiki.dovecot.org/Pigeonhole/Sieve/Plugins/Pipe [2] if environment :matches "imap.user" "*" { set "username" "${1}"; } pipe :copy "sa-learn-spam.sh" [ "${username}" ]; https://doc.dovecot.org/configuration_manual/howto/antispam_with_sieve/#how…

by Marc 24 Sep '22

24 Sep '22

Say for testing purposes I would like to add sender email addresses to a database file (eg gdbm) per user. How would I go about doing this? Do I need to create something like in https://github.com/dovecot/pigeonhole/tree/src/lib-sieve/plugins Or can I just create a go binary, and parse data to it? Is there not something like a hello world example for this?

Duplicate UID warning in dsync backups
by Doug 23 Sep '22

23 Sep '22

Hi, Running dovecot version 2.3.18 with mdbox storage. I run daily backups using dsync on the same server into maildir format. Several times per week I will get an error like the one below that prevents backups from completing. The error is always on my user, never any of my other couple dozen users. dsync(doug): Warning: Deleting mailbox 'INBOX': UID=133060 already exists locally for a different mail: GUIDs don't match (1657786027.M158587P19048.maildev.domain.com vs 581a08178e8ecf62f04700002bad4ea1) dsync(doug): Error: Couldn't delete mailbox INBOX: INBOX can't be deleted. Subsequent backups typically have a slightly different error. dsync(doug): Warning: Deleting mailbox 'INBOX': UID=132994 GUID=407c871b0ec1c562b51000002bad4ea1 is missing locally dsync(doug): Error: Couldn't delete mailbox INBOX: INBOX can't be deleted. Notice the UID and GUID are different from the first error. At this point I will identify 407c871b0ec1c562b51000002bad4ea1 in the source mailbox, and move it to another folder. More often than not that clears things up. The backup command I am using is dsync -u doug all backup maildir:/home/doug/.mailbkup/mailboxes My questions are: Is the "locally" referring to the source or the target of the backup? What might be causing this problem? What the heck is this guid: 1657786027.M158587P19048.maildev.domain.com" Note: The server is actually named mail.domain.com, not maildev.domain.com All file names in the backup maildir have mail.domain.com in them No files exist in the target maildir directory that begin with 1657786027* My original migration from mbox format to mdbox was tested and run on a server named maildev.domain.com. Is that why I am seeing a reference to maildev here? Is that name cached somewhere? Can it be corrected? Does it matter? Are there any options I should add to the dsync command to fix this problem? -- Doug

pigeonhole (manage)sieve directory permissions
by Peter Gervai 22 Sep '22

22 Sep '22

Hello, I've tried to find info (apart from looking at the sources) but it seems this isn't mentioned anywhere. The setting plugin { sieve = file:~/sievedir;active=~/.sievefilter } names the directory where the scripts are stored and the symlink pointing at one. Right now the sievedir seems to be created 0700 plus some - probably inherited - g+s. How could I change mode (to 02770 preferably)? Also the script files are created 0600 by managesieve which really would be nice to be 0660 instead. The main problem is that external programs shall stat() .sievefilter but they only share groups. Thanks, g

Outlook 365 MUA produces dovecot changing filename on some mailbox
by Emilio Augusto Lazo Zaia 21 Sep '22

21 Sep '22

Hello I have a setup on which dovecot is the server in a domain on which mailboxes are >20GB, some of them are 150GB or more. When reconfiguring _some_ mailboxes with Outlook 365 (configuring a previously used mailbox on a new PC), the process takes too long even if mail visibility on Outlook is 3 months. Inspecting at INBOX cur directory I did note that the 'ls' command shows the last file listed is a file from year 2020, 2019 or whatever not being the last received mail; that means the alphabetical ordering of 'ls' is showing past years after the last received mail, i.e. dovecot changed the epoch in filename. This only happens with Outlook. Following is an excerpt of ls: -rw-r--r-- 1 coord.ventas ventas 544765 sep 9 10:57 1662769412.M329925P1259441.xyz.com,S=544765,W=552045:2, -rw-r--r-- 1 coord.ventas ventas 163491 sep 5 12:14 1662769412.M74257P1259441.xyz.com,S=163491,W=165846:2,S -rw-r--r-- 1 coord.ventas ventas 3043536 sep 9 12:02 1662769412.M777084P1259441.xyz.com,S=3043536,W=3083246:2, -rw-r--r-- 1 coord.ventas ventas 161002 feb 27 2020 1662874173.M608062P1282222.xyz.com,S=161002,W=163373:2,S -rw-r--r-- 1 coord.ventas ventas 2230491 feb 27 2020 1662874176.M281294P1282222.xyz.com,S=2230491,W=2259506:2,S -rw-r--r-- 1 coord.ventas ventas 167925 feb 27 2020 1662874176.M741229P1282222.xyz.com,S=167925,W=170373:2,S The process of renaming files is continuous until all folder was reread and renamed every file on it. If I issue 'lsof' (with grep) I see the file that is being renamed passing through tmp/ directory and after that, the file is placed under new/ directory (I guess) and Outlook sees a new email to sync, making the sync process too long... mails that have been synced are resynced... Take a look at the timestamp on filenames: 1662769412 corresponds to "Fri Sep 9 20:23:32 -04 2022" and 1662874176 corresponds to Sun Sep 11 01:29:36 -04 2022 but mails were neither sent nor received on that dates. What is Outlook requesting imap server to do and how to avoid this? Thanks -- Emilio Augusto Lazo Zaia

doveadm-search finds emails, but IMAP search fails to find any
by Philip Warner 20 Sep '22

20 Sep '22

Using dovecot 2.3.7.2 with solr 8.11.2 when I do: doveadm search -u user mailbox INBOX subject "something" I get multiple mail ID's. When I start a manual IMAP session and login as that user, select INBOX, and try the command: . search subject "something" It returns zero mail ID's; this is consistent across all searches using IMAP - no results returned, no matter what I search for in IMAP. The dovecot -n command returns: # 2.3.7.2 (3c910f64b): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.7.2 () # OS: Linux 5.4.0-125-generic x86_64 Ubuntu 20.04.5 LTS # Hostname: WITHELD mail_location = maildir:~/Mail mail_plugins = " fts fts_solr virtual" mail_privileged_group = mail managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate mime foreverypart extracttext namespace { location = virtual:~/Mail/virtual prefix = virtual. separator = . } namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } mailbox virtual.All { comment = All my messages special_use = \All } prefix = } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } passdb { driver = pam } plugin { fts = solr fts_autoindex = yes fts_enforced = yes fts_solr = url=http://localhost:8983/solr/dovecot/ sieve = file:~/sieve;active=~/.dovecot.sieve } protocols = " imap lmtp sieve pop3 sieve" service imap { vsz_limit = 4 G } service index-worker { vsz_limit = 2 G } service indexer-worker { vsz_limit = 2 G } service lmtp { inet_listener lmtp { address = 127.0.0.1 port = 24 } } ssl_cert = </etc/letsencrypt/live/WITHELD/fullchain.pem ssl_client_ca_dir = /etc/ssl/certs ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } userdb { driver = passwd } protocol lmtp { mail_plugins = " fts fts_solr virtual sieve" postmaster_address = WITHELD } protocol lda { mail_plugins = " fts fts_solr virtual sieve" } protocol imap { mail_max_userip_connections = 40 } -

Thunderbird can't connect to Dovecot (bad certificate: SSL alert number 42)
by Meikel 19 Sep '22

19 Sep '22

Hi folks, on a Rocky Linux 8.6 based home server I run Dovecot with an account that I use as an archive. Archive means, that from different Thunderbird instances I connect to that Dovecot via IMAPS to move emails there, that I want to keep. Since some days from all Thunderbird instances I can no longer connect to that Dovecot account. In /var/log/maillog of the server I see Sep 14 06:39:54 server3 dovecot[2033173]: imap-login: Disconnected: Connection closed: SSL_accept() failed: error:14094412:SSL routines:ssl3_read_bytes:sslv3 alert bad certificate: SSL alert number 42 (no auth attempts in 0 secs): user=<>, rip=192.168.177.105, lip=192.168.177.13, TLS handshaking: SSL_accept() failed: error:14094412:SSL routines:ssl3_read_bytes:sslv3 alert bad certificate: SSL alert number 42, session=<dL1luJvokK3AqLFp> I found that Openssl alert number 42 might be a problem with the SSL certificate (which certificate?) but also might be an expired SSL certificate (which certificate?). As on the Dovecot installation I work with a self signed certificat. I created a new self signed certificate yesterday with an expiry not before year 2032. That did not help, I see the same messages when I try to connect from Thunderbird. Just to see how Thunderbird is involved in the problem I installed Claws-Mail. From Claws-Mail I do NOT have those problems, I can access to Dovecot via IMAPS as expected. I do not understand why all my Thunderbird installations can no longer access Dovecot via IMAPS. This worked fine for about 18 months. I can't prove but I think on beginning of month it worked fine. Something happened meanwhile. If there is a problem with an SSL certificate (bad certificate: SSL alert number 42), which certificate makes the problem? The certificate used by Dovecot or some certificate used in Thunderbird?

Bug report: TLS SNI for LDAP userdb/passdb
by Tobias Wolter 18 Sep '22

18 Sep '22

Cheers, Dovecot 2.3.4.1 (Debian stable) here, and the changelog does not offer any hope of salvation, so a bug report it is. The LDAP connections for userdb/passdb do not support SNI via TLS. Simple construct to reproduce this: 0.) Have a.pem with SAN `foo.example.com`, b.pem with `bar.example.com` 1.) Configure haproxy frontend with `bind *:636 ssl crt /foo/a.pem ssl crt /foo/b.pem` 2.) Try to use ldaps://bar.example.com/ in passdb, receive "auth: Error: LDAP: Can't connect to server: ldaps://bar.example.com" Expectation, of course, would be for this to work; most libraries should support it, it's probably just a matter of convincing the appropriate binding. Kind regards, -towo

Overquota flag and auth caching
by Christian Rößner 13 Sep '22

13 Sep '22

Hello, I like the over quota flag mechanism in Dovecot. I found out that I get in trouble if a user gets over quota and I have turned on auth caching, because the cache does not automatically invalidate a user while toggling the flag. The cache still serves the old state. The result is that mails are still accepted, even a user went over quota resulting in bounces. Workaround is to flush a user from inside the toggle script, which solves the bounce problem, but it prevents the user from getting under quota before the user is flushed from the cache again. What is the correct way to use the over quota flag and which solutions can be taken to invalidate the user? Is it possible to do this in a Lua user backend? Any other method?

real duplicates of some e-mails / dovecot-2.3.19
by Götz Reinicke 13 Sep '22

13 Sep '22

Hi, we have the issue, that some(!) e-mails we receive are duplicated when processed by dovecot and stored to the users inbox. The mails are binary identical, same message ID, same size etc. diff sees no difference …. For now we only see that it happens do small mails max. +- 5k in size. And in dose not happen for all mails, but some are spam, some are internal mails some are newsletter which are expected…. and it happens for different users. Dose anyone have/had a similar issue? Any suggestion or idea would be helpful. Thanks . Götz

Handling imap from outlook 365
by Todd Krein 12 Sep '22

12 Sep '22

I apologize if this has been answered before, but... Microsoft Outlook 365 doesn't allow a user to specify the account name for an imap acout, only the email address. Thus fred(a)smith.com<mailto:fred@smith.com> tries to log in as "fred(a)smith.com<mailto:fred@smith.com>" rather than "fred". Has anyone seen a way to fix this (Microsoft help boards are silent), perhaps by stripping the "@smith.com" during the logon procedure?

Outlook 365 (RE: dovecot Digest, Vol 233, Issue 20)
by Todd Krein 12 Sep '22

12 Sep '22

Emilio, Thanks for the suggestions, but neither of these worked for me. Manual setup on Outlook 365 (I think as opposed to Outlook 202x), doesn't let you set the account name directly. It's being "helpful." Interestingly enough, if you set up as POP3, it realizes the account name is wrong and lets you enter it once you try to sync. Not so with IMAP. I was able to create the new account on the control panel, but outlook365 ignores all those accounts.

Unclear how to get both user and domain quotas to work
by Hans van Zijst 10 Sep '22

10 Sep '22

Hi, First of all: my apologies for this long message. I'm trying to post all the information anybody could need to help me on my way. What I'm trying to make is an installation where both users and domains can have quotas. Ideally I would configure a quota for a domain and set a quota of 0 for all users within that domain, so that mail will be accepted up to the point where the domain quota is reached. Setting up user quota was fairly easy, there's lots of documentation around and examples to take inspiration from. Not so much for domain quota however, or I'm really bad at searching the Net. I'm running Debian Bullseye here: MariaDB 10.5.12 Dovecot 2.3.13 Postfixadmin 3.3.10 I want to use dictionaries in MySQL, because eventually this will be a platform with several Dovecot and Postfix servers. At this time I'm only running one Dovecot installation and a few Postfix servers (two for communication with the outside world and one to do the virus and spam scanning). My current setup for user quota is how Postfixadmin wants it: MariaDB [postfixadmin]> desc quota2; +----------+--------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +----------+--------------+------+-----+---------+-------+ | username | varchar(100) | NO | PRI | NULL | | | bytes | bigint(20) | NO | | 0 | | | messages | int(11) | NO | | 0 | | +----------+--------------+------+-----+---------+-------+ 3 rows in set (0.001 sec) In /etc/dovecot/conf.d/90-quota.conf I have this: plugin { quota = dict:User quota::proxy::sqlquota quota_rule = *:bytes=1024M quota_rule2 = Trash:bytes=+100M quota_vsizes = yes quota_status_success = DUNNO quota_status_nouser = DUNNO quota_status_overquota = "552 5.2.2 Mailbox is full" } dict { sqlquota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } The SQL-configuration /etc/dovecot/dovecot-dict-sql.conf.ext is this: connect = host=... dbname=... user=... password=... map { pattern = priv/quota/storage table = quota2 username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota2 username_field = username value_field = messages } map { pattern = shared/expire/$user/$mailbox table = expires value_field = expire_stamp fields { username = $user mailbox = $mailbox } } I use LMTP to accept mail from Postfix; the quota-plugin is activated for LMTP, so every incoming mail should be counted. This works like a charm: if I don't configure a quota for a user, he gets the default 1GB, if I override it in Postfixadmin, then that's what he gets. I'm running quota-status on a TCP-port, so the gateway SMTP-servers can connect to Dovecot for a quotacheck to decide whether to accept or reject an incoming message. Again, this works flawlessly. I can't find any serious documentation about this mapping thing. In particular, what's with that "pattern"? All I can find in the documentation is: "The dict key must match exactly priv/quota/storage. The dict keys are hardcoded in the Dovecot code, so depending on what functionality you’re configuring you need to know the available dict keys used it." -- https://doc.dovecot.org/configuration_manual/dict/#dict-sql If anyone can point me at better documentation than the actual source code: please! I browsed through the quota-plugin source code, but I'm not a programmer and couldn't find what I thought I was looking for. That said, I'm not sure where I got the third "map" from, with the shared/expire pattern. I seem to have forgotten to document that bit of my journey. Now, domain quotas... I've tried all kinds of stuff, but at the moment I'm stuck with something that seems to almost work. I added a second quota root: plugin { quota2 = dict:Domain quota:%d:proxy::sqldomainquota quota2_rule = *:bytes=1024M quota2_status_success = DUNNO quota2_status_nouser = DUNNO quota2_status_overquota = "552 5.2.2 Domain quota exceeded" quota2_vsizes = yes } dict { sqldomainquota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } This dict refers to the same mapping as the one for user quotas, and I think that's the way it should be. Please correct me if I'm wrong. This creates a new user in the quota2 table, by the name of just the domain. Unfortunately, it simply fills it with the numbers from the first user it can find in that domain, not all users in that domain combined. What I think I should do, is change something in the dict so that it sums up all users in that domain, something like this: SELECT SUM(bytes) FROM quota2 WHERE username LIKE '%@domain'; Problem is that I can't find anything useful online with regards to this, I'm not even sure if I'm thinking in the right direction here. Any hints, suggestions or corrections? Or pointers to articles or documentation I might have missed? Kind regards, Hans

Old-stats plugin and fifo_listener permissions
by Grant Keller 10 Sep '22

10 Sep '22

Hello, Currently working on using the old-stats plugin in dovecot version 2.3.10.1. What file permissions are recommended for the old-stats-mail and old-stats-user sockets? I was seeing a lack of data from the doveadm oldstats dump command until I adjusted the default config to the following: service old-stats { fifo_listener old-stats-mail { group = mode = 0666 user = root } fifo_listener old-stats-user { group = mode = 0666 user = } } Not totally clear on which processes need read or write on those so any advice is appreciated.

Managesieve not working
by Francis Augusto Medeiros-Logeay 09 Sep '22

09 Sep '22

Hi, I am running dovecot 2.3.7.2 on ubuntu, and have a replication setup. I noticed that managesieve doesn't seem to be working. On my backup MX, doing a telnet to 4190 gets me the proper greetings, but doing the same on my main server just gave me the normal telnet "Escape character is..." I get the following info on the server: root@d0ba5bb19b6b:/# doveadm service status managesieve name: managesieve process_count: 0 process_avail: 0 process_limit: 1024 client_limit: 1 throttle_secs: 0 exit_failure_last: 0 exit_failures_in_sec: 0 last_drop_warning: 0 listen_pending: n listening: y doveadm_stop: n But when attempting to connect, it doesn't work. Any advice? Best, Francis

Config file syntax: secrets from file in key=value
by Tobias Florek 06 Sep '22

06 Sep '22

Hi! I'd like to set up proxy authentication. This works fine, but I cannot get the passwords in to be read from file. Specifically I have this passdb block. passdb { driver = passwd-file mechanisms = plain scram-sha-256 default_fields = proxy=y host=dovecot-backend master=imapc-master-user proxy_mech=plain pass=</run/secrets/dovecot.imapc-master-user/password args = /run/secrets/dovecot.generated.app-passwd-file/passwd } This sets the password to the string /run/secrets/dovecot.imapc-master-user/password. I'd like the password to be set to the content of said file. Is it possible to get the password from a file or less desirable from the environment? Reading https://doc.dovecot.org/configuration_manual/config_file/ I assume it's not. Cheers, Tobias Florek

Bypass quota check
by Gabriele Nencioni 05 Sep '22

05 Sep '22

Hi all, I have the following quota configuration: lmtp_rcpt_check_quota = no mail_plugins = notify mail_log quota quota = dict:User quota::file:%h/dovecot-quota quota_exceeded_message = Quota exceeded quota_rule2 = Trash:storage=+100M quota_warning = storage=100%% quota-warning -q 100 -n %n -d %d -e OverQuota quota_warning2 = storage=80%% quota-warning -q 80 -n %n -d %d -e FillQuota quota_warning3 = -storage=99%% quota-warning -q 99 -n %n -d %d -e InQuota quota_full_tempfail = yes service quota-warning { executable = script /usr/local/dovecot/quotamanager.sh unix_listener quota-warning { mail_plugins = notify mail_log quota imap_quota imap_sieve mail_plugins = notify mail_log quota sieve and the quota_rule (per-user) is retrieved by a specific SQL query in my userdb. I'm wondering if there is a way to send an email to an account even if it's in overquota? In other words: is there a way to bypass (or skip) the quota check, maybe setting a sort of ACL, for example if an email comes from a specific ip address? Thanks in advance Regards, -- Gabriele Nencioni

Thousands of SSL certificates stalls new logins during reload - problem with Dovecot config process
by Bartosz Kwitniewski 05 Sep '22

05 Sep '22

Hello, I'm running a dovecot 2.3.19.1 server that has around 6000 SSL certificates in separate config files, each containing: local_name "domain" { ssl_cert = ... ssl_key = ... } When new certificate is added, dovecot is reloaded (around 20 times a day). When dovecot is being reloaded, users are unable to log in for around 30 seconds. The main problem here seems to be that during reload, new config process is immediately designated as the one serving config requests and then it starts parsing config files, which takes around 20-30 seconds. If it would parse config files first, and only then would become a new process for serving config requests, then it would probably solve the problem. Or perhaps there is a better way to load new certificates or a way to optimize? There is another problem with config process and shutdown_clients=no. We do not want to disconnect users during reload, because e.g. Thunderbird displays a popup that server is shutting down. When there are long lasting IMAP connections from Google and other services that aggregate e-mail, old config process is not being killed. Because config process with ~6000 certificates is using ~1 GB of RAM, it can quickly rise to 20 GB of memory used. This is not a big issue however, because we have created a task that kills old processes, but there could be a built-in mechanism to solve that problem. I have created minimal configuration and scripts to recreate problem. Reproduction steps below.

Call procmail after sieve
by George Asenov 01 Sep '22

01 Sep '22

Hello, I'm trying to achieve the following scenario with dovecot + sieve + procmail. Dovecot is set as LDA in postfix (if this makes any difference) I need to set sieve that after it has executed all it's scripts (including before, ~/.sieve etc) and if keep is in still in effect to call procmail to also execute the custom user filters and then return (if it is not forwarded elsewhere or some) to dovecot for normal delivery. If you ask this I need this for backward compatibility. I now use procmail for local delivery,spam/virus filtering, and users have set a lot of custom filters/redirects. mailbox_command = /usr/bin/procmail-wrapper -o -a $DOMAIN -d $LOGNAME I want to migrate to dovecot as lda and sieve for filtering but to keep procmail working for a while.
