I found what the problem was. It seems that using ‘.’ as a separator worked. But somehow folders and domain names with dots got messed up: maildir++: root=/var/mail/vmail/francisaugusto/francis, index=/var/mail/vmail/med-lo.eu/francis/shared/index/francis@francisaugusto, indexpvt=/var/mail/vmail/med-lo.eu/francis/shared/francis@francisaugusto, control=, inbox=/var/mail/vmail/francisaugusto/francis, alt= Sep 25 19:10:57 imap(francis(a)med-lo.eu)<58061><skunigB>: Debug: Namespace shared.francis@francisaugusto.: Creating storage despite: Root mail directory doesn't exist: /var/mail/vmail/francisaugusto/francis You see, my domain is francisaugusto.com <http://francisaugusto.com/>, but it got truncated. I changed the separator to ‘/‘ on the Inbox namespace and on the shared one, and voila, it worked. I can see my shared mailboxes everywhere. But on Apple Mail (both on the Mac and on the iPhone), the shared mailboxes show no message. Any clue why?

Sieve vacation function sends auto-reply with generic From: Address
by Thomas Boroske 25 Sep '23

25 Sep '23

Good day to you all. I have a question regarding the dovecot sieve vacation function that I am unable to answer myself by reading the documentation. A while ago we moved our dovecot server to a newer system (and newer dovecot version 2.3.16 ). This worked mostly fine, except there is now an issue with the auto-reply emails send from sieve vacation scripts. While the sending of the auto reply generally works fine, the emails always appear to come from the "sysgroup(a)ida.ing.tu-bs.de" address rather than the original recipient of the message. This is bad since the recipient of the auto reply then has no idea who the person on vacation actually is (unless there is a name in the message body). The sieve scripts are managed by roundcube webmail, an example entry for a vacation rule looks like this: require ["vacation"]; # rule:[Vacation] if true { vacation :days 7 :subject "Nicht im Büro" :from "tbtest(a)ida.ing.tu-bs.de" "Ich bin nicht da!"; } This looks ok to me. The problem is that the "tbtest" address is not used in the generated reply, instead sysgroup(a)ida.ing.tu-bs.de is used as a from address for all recipients. Note that the sysgroup@ address appears nowhere in the dovecot config, but it does in /etc/postfix/sender-canonical like that: root(a)ida.ing.tu-bs.de sysgroup(a)ida.ing.tu-bs.de @ida.ing.tu-bs.de sysgroup(a)ida.ing.tu-bs.de @net.ida sysgroup(a)ida.ing.tu.bs.de The /etc/dovecot/conf.d/90-sieve.conf is mostly on default values, the remaining config settings are these: plugin { sieve = file:~/Maildir/sieve;active=~/Maildir/.dovecot.sieve sieve_extensions = +editheader #Send vacation auto responder with correct Address sieve_vacation_send_from_recipient = yes sieve_vacation_use_original_recipient = no } I have attached the output of "dovecot -n" below. Many thanks for any ideas on what could be the issue! Kind regards, Thomas -- Dipl. Inf.

All list=yes namespaces must use the same separator - don't they?
by Francis Augusto Medeiros-Logeay 25 Sep '23

25 Sep '23

Hi, I am trying to configure shared mailboxes, so I enabled the acl and the imap_acl plugins. But I got the "All list=yes namespaces must use the same separator" error when I added this: namespace { type = shared #separator = # Mailboxes are visible under "shared/user@domain/" # %%n, %%d and %%u are expanded to the destination user. prefix = shared/%%u/ # Mail location for other users' mailboxes. Note that %variables and ~/ # expands to the logged in user's data. %%n, %%d, %%u and %%h expand to the # destination user's data. location = maildir:/var/mail/vmail/%%d/%%n:INDEX=/var/mail/vmail-index/index/%%d/%%n:INDEXPVT=/var/mail/vmail-index/index/%%d/%%n # Use the default namespace for saving subscriptions. subscriptions = no # List the shared/ namespace only if there are visible shared mailboxes. list = children } I don't have any separator configured explicitly, and when I see the config, the value is empty. So I don't really know what is the problem here. Any hints? Best, Francis -- Francis Augusto Medeiros-Logeay Oslo, Norway

possible doveadm expunge bug
by Noel Butler 24 Sep '23

24 Sep '23

In my boredom, I was cleaning up my own public mailbox, do I really need lists/newsletters/forums posts from the 90's .. I think not, but lets still keep 5 years and expunge the rest... or try to... but expunge doesnt want too... This error or lack of action, occurs on any mailbox, as an example doveadm expunge -u my@email mailbox Lists.FreeRadius SAVEDBEFORE $ now for $, pick your value 5 y/Y for years doesn't appear to exist, so converting it into 30 odd weeks, 30w or 30W did nothing, but rough convert it down to days 1800D appears to do something - showing a delay before returning to command line, but in reality it does nothing, 1800, 1500, 1200, nothing, only when I drop it to 1000D does it actually work, which is not suitable, since I'd like to keep 5 years worth. Running doveadm -Dv exp... shows no errors just usual debug output about the base modules, quota stuff, and opening mailbox message followed then by user session closed, nothing at all anywhere that points to an error for executing this task, I did deliberately break it by altering the mailbox name to test and it rightfully did report the error the mailbox doesn't exist. I thought it might be size related, freeradius one of the smaller lists having about 150k to nanog the biggest with over 400k message, but I have others, like monthly newsletters with over 20yrs worth, but only 250 to 300 messages in their mailboxes that also fail, so it can't be barfing out at the size. Aki, any ideas? Or have I have hit a ridiculously low 1000D hard coded limit? ...and I know some troll will comment, so let me say yes I know I can and will likely have to use nix's "find" to actually cull them, but if doveadm has an expunge option, it should do what it is asked of it :) # doveconf -a # 2.3.20 (80a5ac675d): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.20 (149edcf2) # OS: Linux 5.15.117 x86_64 Slackware 15.0 ext4 - Yes I know 2.3.21 was released 2 days ago, but I'm not seeing anything in changelog/NEWS that's related -- Regards, Noel Butler This Email, including attachments, may contain legally privileged information, therefore at all times remains confidential and subject to copyright protected under international law.

Dovecot OIDC question
by dovecot＠deeztek.net 23 Sep '23

23 Sep '23

Exploring the possible use of SSO using OIDC with Dovecot. Trying to understand the functionality of OIDC as it pertains to e-mail clients like Thunderbird, Outlook etc... My OIDC provider will authenticate a user by intercepting the connection attempt to the resource, present a login screen and after success it will redirect to the resource. When it comes to e-mail clients, how would that process work if at all? Thanks

2.3.21 broke XOAUTH authentication against Keycloak
by tj＠interseclab.org 23 Sep '23

23 Sep '23

I have Roundcube and Dovecot2 setup to authenticate against Keycloak using the XOAUTH2 method, as follows: introspection_url = https://[...]/realms/[...]/protocol/openid-connect/token/introspect introspection_mode = post username_attribute = email client_id = [...] client_secret = [...] tls_ca_cert_file = /etc/ssl/certs/ca-certificates.crt Since upgrading to 2.3.21 XOAUTH2 fails to authenticate with: dovecot: auth: Error: oauth2([...],[...],<[...]>): oauth2 failed: Introspection failed: No username returned WARN [org.keycloak.events] (executor-thread-45) type=INTROSPECT_TOKEN_ERROR, realmId=[...], clientId=null, userId=null, ipAddress=[...], error=client_not_found WARN [org.keycloak.events] (executor-thread-45) type=INTROSPECT_TOKEN_ERROR, realmId=[...], clientId=null, userId=null, ipAddress=[...], error=invalid_request, detail='Authentication failed.' Downgrading to 2.3.20 fixes the issue. I believe this change is to blame: lib-oauth2: Dovecot would send client_id and client_secret as POST parameters to the introspection server. These need to be optionally in Basic auth instead. Is there anything I should change in my Keycloak/Dovecot config or is this a bug?

Change location where .dovecot.lda-dupes* file/dir are created
by sahsanu 22 Sep '23

22 Sep '23

Hello, I'm using Dovecot 2.3.19.1 and Pigeonhole 0.5.19 on Debian 12.1 and I'm trying to use sieve extensions vacation and redirect but I'm having issues because of the creation of file /home/USER/.dovecot.lda-dupes and dir /home/USER/.dovecot.lda-dupes.locks The error in logs is pretty clear, lda doesn't have perms to create any of them because /home/USER/ is owned by root # namei -mo /home/user2/ f: /home/user2/ drwxr-xr-x root root / drwxr-xr-x root root home drwxr-xr-x root root user2 I'm using Hestia Control Panel and it chroot the users and that is the reason the user's home is owned by root. Mail users are virtual and the maildir home is /home/user2/mail/domain2.tld/postmaster (%h/mail/%d/%n) but the .dovecot.lda-dupes* file and dir are trying to use /home/user2/ instead of /home/user2/mail/domain2.tld/postmaster/ where they have perms and that should solve the issue. So, the question, is there any way to create .dovecot.lda-dupes* file/dir in virtual user's home %h/mail/%d/%n instead of user's home %h? or, is there any other solution/workaround where I don't need to change /home/USER/ owner/perms? If you want to check them, below are the logs and my dovecot conf. Appreciate your support.

State of wiki.dovecot.org?
by Sebastian Philipp 20 Sep '23

20 Sep '23

Hi all I just noticed that wiki.dovecot.org is no longer available, and instead redirects to a message stating that the documentation can now be found at doc.dovecot.org. However, there's was quite a lot of information on wiki.dovecot.org that is not available on doc.dovecot.org. One such example is the setup guide for a Dovecot Director cluster [1]. The "corresponding" page on doc.dovecot.org [2] even starts with the following sentence: > See http://wiki.dovecot.org/Director for more details. Are there plans to migrate such pages to doc.dovecot.org as well? If not, could the Wiki be restored? Of course it's possible to access the Wiki contents via web.archive.org, but that's rather cumbersome and slow.

Hi When will there be a new dovecot release. The 2.3.21 version borked our users with large amount of folders (i think over 255 folders) doveadm(REDACTED_USER): Error: /proc/self/status is larger than expected I can't find the debian bug report (or was it mentioned in this same mailing list), but somebody else has mentioned the same issue. I hope this gets fixed in the next version. -- Taavi Ansper taavi.ansper(a)cyber.ee

dovecot username with domain
by Michael Grant 19 Sep '23

19 Sep '23

I've been using dovecot using system usernames (my unix uname as my IMAP username). But today I tried New Outlook which requires the imap username match my email address. Is there some way to tell dovecot that username@host is the same as uname? (where username@host is an email address and uname is a unix login which might be completely different). Michael Grant

Logging for doveadm index?
by Shawn Heisey 15 Sep '23

15 Sep '23

I have dovecot using Solr for FTS. Dovecot version is 2:2.3.20-3+ubuntu20.04 pulled from the official APT repo. This is my reindex script: https://paste.elyograg.org/view/74accd23 The reindex script kicks off the indexing process in the background. Dovecot logs to syslog, and those logs ultimately end up in mail.log. I have not seen any logging for the FTS reindexing. Specifically I would like to see how long the process took. Getting that info from the solr logs is a manual process and I can't think of a way to properly automate it. Is this something I can easily have dovecot log? Or is there a way to have 'doveadm index' run in the foreground instead of the background so the time can be calculated by my script? Thanks, Shawn

Dovecot v2.3.21 released

15 Sep '23

Hi all! We are pleased to release v2.3.21 of Dovecot. https://dovecot.org/releases/2.3/dovecot-2.3.21.tar.gz https://dovecot.org/releases/2.3/dovecot-2.3.21.tar.gz.sig Binary packages in https://repo.dovecot.org/ Docker images in https://hub.docker.com/r/dovecot/dovecot Regards, Aki Tuomi Open-Xchange oy --- * lib-oauth2: Allow JWT tokens to be validated with missing typ field. The typ field is left out by some key issuers to conserve space, notably kubernetes. Now missing typ is tolerated, but if present, it still must be "jwt". + auth: Auth passdb and userdb reply can contain "event_<name>=value" which will be added to login event and mail user event respectively. + lib-master: Set process title during various initialization stages to clearly describe what the process is waiting on. + lib-storage: The mail_temp_scan_interval is now fuzzed incrementing it by 0..30% based on username's hash to reduce the chance of load spikes . + lib-storage: The temp file scan has been moved from the open of the mailbox to the close, to reduce the latency perceived by users. + stats: If metric has fields specified, all these fields are exported as counters to prometheus exposition. See https://doc.dovecot.org/configuration_manual/stats/openmetrics/. - *-login: Processes might have crashed when a SSL connection disconnect s uncleanly. - acl: When plugin was loaded \HasChildren and \HasNoChildren flags were calculated incorrectly for mailboxes containing '*' and '%' in their names. - auth: Crash occured if a connection to PostgreSQL database server failed during startup. - auth: Logins with invalid passwords (e.g. unknown scheme) in passdb were failing with "password mismatch" instead of "internal error". - auth: XOAUTH2 and OAUTHBEARER mechanisms were not giving out protocol specific error message on all errors. This especially broke OIDC discovery. - dbox: When last_temp_file_scan header wasn't set (especially after dsync migration), the next mailbox open always triggers the temp file scan. This could have caused a load spike after migrations. Fixed by using the mailbox directory's atime when the header isn't set, which usually moves the scan time into the future. - dict-redis: A crash would occur on transaction rollback. - dsync: Infinite loop causing out of memory would occur when handling mailbox deletion from remote end and hierarchy separators would differ. - dsync: Incremental dsync failed for folder names ending with '%', unless BROKENCHAR was set. Also folder names with '%' elsewhere in them caused each incremental dsync to unnecessarily rename the folder to a temporary name and back. v2.3.19 regression. - imap-hibernate: If an IMAP client unhibernation timed out with "(version received)", the unhibernation could still have successfully finished later on and continued working normally. This was rather confusing, because imap-hibernate already logged that the client got disconnected. Avoid this by forcing the connection to shutdown on unhibernation timeout. - imapc: Crashed when a folder mapped through the virtual plugin disappears from the storage. - imapc: EXPUNGE, EXISTS or FETCH replies from a server for a previously selected mailbox could have been processed as if they belonged to the new mailbox currently being selected. This could have caused warnings. - lib-http: Dovecot HTTP server (doveadm, stats/openmetrics) may have disconnected HTTP clients before the response is fully sent. This happened only on busy servers where kernel's socket buffers were rather full. - lib-http: Fixed a potential crash on http-server if a client disconnected early. v2.3.18 regression. - lib-index: Index file corruption could have caused a crash. Fixes: Panic: file mail-transaction-log-view.c: line 165 (mail_transaction_log_view_set): assertion failed: (min_file_seq <= max_file_seq). - lib-index: Purging an existing >1GB cache file can crash. Now cache files still above 1GB after purging are removed. Fixes: Panic: file mail-index-util.c: line 10 (mail_index_uint32_to_offset): assertion failed: (offset < 0x40000000) - lib-lua: A HTTP client could not resolve DNS names in mail processes, because it expected "the dns-client" socket to exist in the current directory. - lib-oauth2: Dovecot would send client_id and client_secret as POST parameters to the introspection server. These need to be optionally in Basic auth instead. - lib-oauth2: JWT aud validation was not performed if aud was missing from a token, but was configured on Dovecot. - lib-oauth2: JWT key type check was too strict. - lib-oauth2: JWT token audience was not validated against client_id as required by the specification. - lib-ssl-iostream: Using the ssl_require_crl=yes setting may have caused CRL check failures for outgoing SSL/TLS connections, although it was supposed to affect checking CRLs only for client-side SSL certificates. v2.3.17 regression. - lib-sql: MySQL driver leaked memory when connection failed. - lib-storage: Various fixes when running into out of disk space. - master: Service idle_kill setting didn't work properly on busy servers. It was very unlikely that any process was idling long enough to become killed. Also the idle_kill handling code was using quite a lot of CPU on the master process when there were a lot of processes (e.g. imap). The new behavior is to track the lowest number of idling processes every idle_kill time interval and then kill that many idling processes. - mdbox: Temp file scan was done for always empty directories. - mdbox: The fdatasync() call was done in wrong parent directory when writing mails. Also on a failure it crashed instead of logging an error. - notify_status: The plugin crashes if any user initialization fails. - pop3: Sending command with the ':' character caused an assert-crash. v2.3.18 regression. Fixes: Panic: event_reason_code_prefix(): name has ':' - stats: Fix panic when a nonexistent event exporter was referenced while adding a new metric dynamically via doveadm stats add. This produces a proper error now. - stats: If process exported a lot of events and then exited, some of the last events may have become lost. - stats: Invalid Prometheus label names were created with specific histogram group_by configurations. Prometheus rejected these labels. - welcome: The plugin didn't execute in some situations that created INBOX but didn't open it, e.g. if GETMETADATA was used before the INBOX was opened.

config: Error: Conflict in setting ssl_cert found from filter
by Ján Ondrušek 15 Sep '23

15 Sep '23

Hi! I see this intermittent error with my dovecot setup. The most puzzling part is that it sometimes works and sometimes rejects connections, spitting out the log I attached in systeport (DNS). I am binding both ipv4 (TLS+SNI) and ipv6 (dedicated addresses). TLS certificates for corresponding DNS are shared across ipv4 / ipv6. Thank you, Best regards, Jan

ACL management from SQL
by cyril.leclerc＠mantiq.com 14 Sep '23

14 Sep '23

Hello, we are facing issue, we manage the shared folder from SQL table, but it was never working as we have to manage acl permission from the server itself, we want to manage permissions (read or write) from the same application we can share user mailbox but it is written in dovecot documentation that is not supported now, we tried to find a mail client that could manage it at least, but only thunderbird was able to do it (but in version 60) and not more today. We saw that roundcube could handle it but we use rainloop. 1. It is really not possible at all to manage acl permissions fron SQL like the shared box itself ? 2. I tried to set acl permissions from old version of thunderbird, when i made modification it tried to update the sharedbox table, i did not see the query executed but as we were working on a view, the update failed. Do you know what it tried to do ?

Shared mailbox listing not working
by exactoph 14 Sep '23

14 Sep '23

Hi there, Having trouble with shared mailboxes. Followed the documentation, but the IMAP LIST doesn't work for mailboxes besides "INBOX" etc. In the meantime I've switched from file based acl_shared_dict to DB based as some people had problems with it. However still no success. I can see entries in the DB, doveadm acl get ... returns that the mailbox is shared, but it is not listed in doveadm mailbox list ... My configuration: https://pastebin.com/aWnMXJ4J Help would be very appreciated!

OK, even though the service desk doesn't know how to answer the above questions about IPv6 correctly, the information *is* available if you dig hard enough. And it seems to work. Can you get a PTR6 record for your mail server? No. At least, not from my upstream. Begins with "A" and ends with "T". Don't even ask about reverse delegations, the blank stare will scare you. (I apologize to everyone on this list. The above diatribe more correctly lives on mailing lists for Sendmail, Postfix, Exim, and other packages that actually originate mail exchanges.)

DOvecot requires both IPv4 and IPV6 to start
by TWHG Technical 06 Sep '23

06 Sep '23

I think we are off topic. We have a network policy that until such time as we have fully implemented the same security we have on our IPV4 network we simply do not allow IPV6 as it is another attack vector we are not fully upto speed on. So we block all IPV6 at the perimeter and on all switches, firewalls and routers. So if you connect to our network with a device no IP6 is configured and only IPV4 is allowed. We will get there! But that is not this issue. The issue is that dovecot is assuming that IPV6 is there and crashes out if it's not. Hacking the config to only listen on IP4 solves the problem but not while installing from standard repos to install the currently supported version. Cheers Spart

Hi, I'm running a postfix smtp relay server on which users are getting authenticated trough sasl via the dovecot authentication service. This works without problems. Recently I extended my configuration to authenticate users with the PLAIN mechanism against Azure AD B2C with oauth2 in the future.

DOvecot requires both IPv4 and IPV6 to start
by TWHG Technical 04 Sep '23

04 Sep '23

Hello, I hope this is the right place to start. Ubuntu server the default listener configuration in dovecot.conf uses both IP4 and IP6 on systems that have IP6 disabled dovecot will not start. Is it possible to set the default to: listen = * to only bind to IP4 for installation and initial start. Rather than listen = *, :: which tries to bind to a non existent IP6 stack. Or simply fallback to ip4 if ip6 is not available. Thank you

IPV6 is disabled in the grub command line. So before the OS boots. So there is no IPV6 support in the system. Unless one enables it in the Grub bootloader. Cheers

I have tried replying twice. We have IPV6 disabled for security reasons on all server builds. An installer script failed which is how we caught this issue. We can see it is due to the config line. A graceful fallback to IPV4 if the IPV6 stack is not available would seem to be an elegant solution that would make dovecot resilient in all circunstances. Cheers Spart

no such user but Thunderbird okeys it ?
by lejeczek 04 Sep '23

04 Sep '23

Hi guys. I'm having quite bizarre situation where Dovecot logs: ... pam_unix(dovecot:auth): check pass; user unknown pam_unix(dovecot:auth): authentication failure; logname= uid=0 euid=0 tty=dovecot ruser=dupa rhost=AA.BB.CC.DD imap-login: Login: user=<dupa>, method=PLAIN, rip=AA.BB.CC.DD, lip=AA.BB.CC.DD, mpid=1756629, TLS, session=<uV7OwIIEWsJdviSg>: ... but Thunderbird allows, is okey with such user & creates an account for it. I must be having my setup miss-configured - I'm hoping it's something obvious somebody could point me towards. many thanks, L.

Dovecot director and backend on same server
by Michael Cassaniti 29 Aug '23

29 Aug '23

Hi, I'm attempting to run both the director and the backend under the same configuration on the same server. When I run doveadm director map I don't get any output. I have a shared file system between servers and clients can access any server. I was running without a director in front and seeing index corruption so I'm now attempting to use a director. I enabled additional logging for now but that didn't explain much. Dovecot version: 2.3.20 (80a5ac675d) on Alpine Linux v3.18.2 Dovecot configuration (doveconf -n) with some bits removed. # Pigeonhole version 0.5.19 (4eae2f79) # OS: Linux 6.1.43-0-lts x86_64 # Hostname: <REDACTED> auth_debug = yes auth_socket_path = director-userdb director_mail_servers = 192.168.252.2 192.168.252.3 192.168.252.4 192.168.252.5 192.168.252.20 director_servers = 192.168.252.2 192.168.252.3 192.168.252.4 192.168.252.5 192.168.252.20 imap_hibernate_timeout = 5 secs log_debug = events=* login_trusted_networks = 192.168.252.0/24 mail_debug = yes mail_fsync = always mail_gid = vmail mail_location = maildir:~/Maildir:LAYOUT=fs mail_nfs_index = yes mail_nfs_storage = yes mail_plugins = acl quota mail_uid = vmail 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 imapsieve vnd.dovecot.imapsieve mmap_disable = yes namespace inbox { inbox = yes location = mailbox Bin { auto = subscribe autoexpunge = 30 days special_use = \Trash } mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Spam { auto = subscribe autoexpunge = 30 days special_use = \Junk } prefix = } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { acl = vfile quota = maildir:quota quota_rule = *:storage=5G quota_rule2 = Bin:ignore quota_rule3 = Spam:ignore sieve = file: ~/sieve;active=~/dovecot.sieve sieve_plugins = sieve_imapsieve } protocols = imap lmtp sieve service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } service director { fifo_listener login/proxy-notify { mode = 0600 user = $default_login_user } inet_listener { port = 9090 } unix_listener director-admin { mode = 0600 } unix_listener director-userdb { mode = 0600 } unix_listener login/director { mode = 0666 } } service imap-login { executable = imap-login director } service imap { user = vmail } service ipc { unix_listener ipc { user = dovecot } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } user = vmail } service managesieve-login { executable = managesieve-login director inet_listener sieve { port = 4190 } } ssl = required ssl_cert = </etc/letsencrypt/live/<REDACTED>/fullchain.pem ssl_cipher_list = HIGH:!SSLv3:!aNULL ssl_key = # hidden, use -P to show it userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol lmtp { mail_plugins = acl quota sieve } protocol imap { mail_plugins = acl quota imap_acl imap_quota imap_sieve imap_zlib } Regards, Michael Cassaniti

Dovecot, mail_crypt, global keys, permissions
by David Mehler 28 Aug '23

28 Aug '23

Hello, I'm using Dovecot v2.3 with the mail_crypt plugin and global keys. I am seeing this error immediately after imap login then after this error imap logs out. I'm hoping this is a simple permissions problem and the key can not be read rather than an underlying configuration issue. I do not know what this UID 5395 refers to. 2023-08-11T04:14:14.539308-04:00 hostname dovecot: imap(username(a)domain.org)<492738><zO4WTKECnvRoDWll>: Error: Mailbox INBOX: UID=5395: read() failed: read(/var/mail/mailboxes/domain.org/username/mail/mailboxes/INBOX/dbox-Mail… failed: Private key not available: mailbox_attribute_get(INBOX, /priv/vendor/vendor.dovecot/pvt/crypt/privkeys/e9f195fe9fd1953d08e815ba6fda9b6c5ae1ed692c9adade2f958c322552cbb0) failed: Mailbox attributes not enabled (FETCH BODY[HEADER]) #ls -ld crypt drwxr-xr-x 2 root root 4096 Jul 25 08:52 crypt/ # cd crypt #ls -l * -r-------- 1 root root 241 Jul 25 15:43 master.key -rw-r--r-- 1 root root 178 Jul 25 15:43 master.pub Thanks.

Bug - doveadm backup out-of-memory kill/crash when no separators set
by James Harrison 26 Aug '23

26 Aug '23

Hi, I hit a fun issue with doveadm when migrating from dovecot 2.2.36 (1f10bfa63) to 2.3.19.1 (9b53102964) (CentOS 7 to Debian 12). When running doveadm -v -D backup -R -u "user@name" tcp:localhost:1234, I found that the first sync would always work, but subsequent runs of the command would cause doveadm to reach a subfolder (Archives/2008 in the example below) and then silently mmap() increasing powers of 2 before the OOM killer finally got it. Deleting the source folder caused it to remain stuck on the same folder, but for the deletion event. I switched memory overcommit off to force a crash, and got a gdb backtrace: #0 __pthread_kill_implementation (threadid=<optimized out>, signo=signo@entry=6, no_tid=no_tid@entry=0) at ./nptl/pthread_kill.c:44 #1 0x00007ffff786bd9f in __pthread_kill_internal (signo=6, threadid=<optimized out>) at ./nptl/pthread_kill.c:78 #2 0x00007ffff781cf32 in __GI_raise (sig=sig@entry=6) at ../sysdeps/posix/raise.c:26 #3 0x00007ffff7807472 in __GI_abort () at ./stdlib/abort.c:79 #4 0x00007ffff7b4ffae in default_fatal_finish (status=0, type=LOG_TYPE_PANIC) at ../lib/failures.c:465 #5 fatal_handler_real (ctx=<optimized out>, format=<optimized out>, args=<optimized out>) at ../lib/failures.c:477 #6 0x00007ffff7bfa081 in default_fatal_handler (ctx=<optimized out>, format=<optimized out>, args=<optimized out>) at ../lib/failures.c:485 #7 0x00007ffff7b5017c in i_panic (format=0x7ffff7c5d748 "data stack: Out of memory when allocating %zu bytes") at ../lib/failures.c:530 #8 0x00007ffff7b4f67f in mem_block_alloc (min_size=min_size@entry=16) at ../lib/data-stack.c:386 #9 0x00007ffff7bf8b60 in t_malloc_real (size=<optimized out>, permanent=<optimized out>) at ../lib/data-stack.c:492 #10 0x00007ffff7c348f1 in t_strdup_until (start=start@entry=0x55555565f440, end=end@entry=0x55555565f448) at ../lib/strfuncs.c:270 #11 0x00005555555adc62 in convert_name_to_remote_sep (name=0x55555565f440 "Archives/2008", tree=0x55555564e188) at dsync/dsync-mailbox-tree.c:270 #12 dsync_mailbox_tree_build_name128_remotesep_hash (tree=0x55555564e188) at dsync/dsync-mailbox-tree.c:315 #13 dsync_mailbox_tree_find_delete (tree=0x55555564e188, del=0x5555556469f0) at dsync/dsync-mailbox-tree.c:405 #14 0x00005555555a4195 in dsync_brain_mailbox_tree_add_delete (tree=0x55555564e188, other_tree=0x55555564f5f8, other_del=0x5555556469f0, node_r=0x7fffffffe350, status_r=0x7fffffffe348) at dsync/dsync-brain-mailbox-tree.c:504 #15 0x00005555555a44cd in dsync_brain_recv_mailbox_tree_deletes (brain=0x55555564b2d8) at dsync/dsync-brain-mailbox-tree.c:590 #16 0x00005555555a5365 in dsync_brain_run_real (brain=brain@entry=0x55555564b2d8, changed_r=changed_r@entry=0x7fffffffe453) at dsync/dsync-brain.c:709 #17 0x00005555555a59f9 in dsync_brain_run (changed_r=0x7fffffffe453, brain=0x55555564b2d8) at dsync/dsync-brain.c:752 #18 dsync_brain_run (changed_r=0x7fffffffe453, brain=0x55555564b2d8) at dsync/dsync-brain.c:740 #19 dsync_brain_run_io (context=<optimized out>) at dsync/dsync-brain.c:113 #20 dsync_brain_run_io (context=0x55555564b2d8) at dsync/dsync-brain.c:100 #21 0x00005555555b23df in dsync_ibc_stream_input (ibc=0x555555646720) at dsync/dsync-ibc-stream.c:232 #22 0x00007ffff7c11cd9 in io_loop_call_io (io=0x5555556418f0) at ../lib/ioloop.c:737 #23 0x00007ffff7c13aa2 in io_loop_handler_run_internal (ioloop=ioloop@entry=0x55555560bf40) at ../lib/ioloop-epoll.c:222 #24 0x00007ffff7c13b50 in io_loop_handler_run (ioloop=ioloop@entry=0x55555560bf40) at ../lib/ioloop.c:789 #25 0x00007ffff7c13d10 in io_loop_run (ioloop=0x55555560bf40) at ../lib/ioloop.c:762 #26 0x000055555558b22e in cmd_dsync_run_remote (user=0x555555637248) at ./src/doveadm/doveadm-dsync.c:543 #27 cmd_dsync_run (_ctx=0x55555561f288, user=0x555555637248) at ./src/doveadm/doveadm-dsync.c:750 #28 0x000055555558bd12 in doveadm_mail_next_user (ctx=0x55555561f288, error_r=0x7fffffffe818) at ./src/doveadm/doveadm-mail.c:464 #29 0x000055555558cf45 in doveadm_mail_cmd_exec (wildcard_user=0x0, ctx=0x55555561f288) at ./src/doveadm/doveadm-mail.c:659 #30 doveadm_cmd_ver2_to_mail_cmd_wrapper (cctx=0x7fffffffe970) at ./src/doveadm/doveadm-mail.c:988 #31 0x0000555555597622 in doveadm_cmd_run_ver2 (argc=5, argv=0x55555560ba38, cctx=cctx@entry=0x7fffffffe970) at ./src/doveadm/doveadm-cmd.c:465 #32 0x0000555555597697 in doveadm_cmd_try_run_ver2 (cmd_name=<optimized out>, argc=<optimized out>, argv=<optimized out>, cctx=0x7fffffffe970) at ./src/doveadm/doveadm-cmd.c:363 #33 0x000055555557919a in main (argc=<optimized out>, argv=<optimized out>) at ./src/doveadm/doveadm.c:361 Neither server had a separator set in the inbox namespace. Having identified the convert_name_to_remote_sep function as the likely trigger point I set the separator to / on both ends, and doveadm backup now runs without issue. Can provide config if helpful but I think probably irrelevant to this one - the namespace config is the default other than the separator item. May be worth mentioning that having the separator set can avoid this condition in the doveadm backup docs - this took me a while to figure out! -- Cheers, James Harrison

Stop Logging to Syslog
by Asai 25 Aug '23

25 Aug '23

Greetings, My logging config is as follows: # doveadm log find Debug: /var/log/dovecot-debug.log Info: /var/log/dovecot.log Warning: /var/log/dovecot.log Error: /var/log/dovecot.log Fatal: /var/log/dovecot.log However, I'm still getting logs in /var/log/messages which I don't want. I've looked into /etc/rsyslog.conf for clues, but can't find anything that would point to Dovecot logging to /var/log/messages. Can anyone point me in the right direction here? Thank you, Asai

sievec: Misleading error message
by Horst Prote 25 Aug '23

25 Aug '23

Hi, in a sieve script I just made a syntax error and got this error message on calling sievec: error: the else command must follow an if or elseif command. My first thougth was "Are you kidding me!" as I used "elseif". But then I realized that the correct syntax is "elsif". So I think that error message should be corrected to error: the else command must follow an if or elsif command. Thanks, Horst

dovecot 2.4 issue with openssl >= 3.0.8

From https://www.openssl.org/docs/man3.0/man7/EVP_KEYMGMT-EC.html """ Before OpenSSL 3.0.8, the implementation of providers included with OpenSSL always opted for an encoding in compressed format, unconditionally. Since OpenSSL 3.0.8, the implementation has been changed to honor the OSSL_PKEY_PARAM_EC_POINT_CONVERSION_FORMAT parameter, if set, or to default to uncompressed format.""" I don't see simple way how to force compressed format just for dumping data without effecting the key itself. Method that can be used with compression format argument is EC_POINT_point2hex but it requires quite lengthy extraction of EC_POINT first. I've tried this for testing with: static const char *ec_key_get_pub_point_hex(const EVP_PKEY *pkey) { if (!EVP_PKEY_is_a(pkey, "EC")) return NULL; size_t len; EVP_PKEY_get_utf8_string_param(pkey, OSSL_PKEY_PARAM_GROUP_NAME, NULL, 0, &len); buffer_t *parambuf = t_buffer_create(len+1); EVP_PKEY_get_utf8_string_param(pkey, OSSL_PKEY_PARAM_GROUP_NAME, (char *)parambuf->data, len+1, &len); int nid = OBJ_txt2nid(parambuf->data); EVP_PKEY_get_octet_string_param(pkey, OSSL_PKEY_PARAM_PUB_KEY, NULL, 0, &len); parambuf = t_buffer_create(len+1); EVP_PKEY_get_octet_string_param(pkey, OSSL_PKEY_PARAM_PUB_KEY, (unsigned char *)parambuf->data, len+1, &len); EC_GROUP *ec_grp = EC_GROUP_new_by_curve_name(nid); if (ec_grp == NULL) return NULL; EC_POINT *point = EC_POINT_new(ec_grp); if (point == NULL) { EC_GROUP_free(ec_grp); return NULL; } if (!EC_POINT_oct2point(ec_grp, point, parambuf->data, len, NULL)) return NULL; char *ret = EC_POINT_point2hex(ec_grp, point, POINT_CONVERSION_COMPRESSED, NULL); EC_GROUP_free(ec_grp); EC_POINT_free(point); return ret; } and it fixed the issue, but there may be an easier way how to achieve that.

Question about namespaces
by J Doe 21 Aug '23

21 Aug '23

Hello, I have a question regarding namespaces. My current dovecot.conf is rather basic when it comes to namespaces - I have one private namespace per user: namespace inbox { type = private separator = / inbox = yes hidden = no list = yes subscriptions = yes } I have some users who connect via more than one client - for instance, some use Apple Mail in addition to Roundcube. I have noticed that different mail clients sometimes create similar mailboxes, such as Trash and Deleted Items. I would like the same mailboxes across any client, so I am wondering if there is a way in Dovecot to specify the folders and have the *client* not create them. For instance, a config in dovecot.conf that specifies a Trash folder and the mail clients cannot create "Deleted Items", etc. in addition to this. Is this possible ? Thanks, - J

Backing up m(d)box - rsync?
by donotspam＠fastmail.fm 19 Aug '23

19 Aug '23

Hello, I manage a small number of email accounts for a voluntary organisation on a shared hosting platform. $ dovecot --version 2.3.13 (89f716dc2) I would like to keep automated local backups, but do not have access to doveadm. I have seen a couple of forum posts where users have have suggested that using rsync to backup m(d)box folders can corrupt dovecot's indexes, but there is no further explanation, and this is apparently not a problem for maildir. Our host seems to use mdbox. Does doveadm provide some sort of transaction/locking mechanism to prevent consistency problems? Others seem to recommend using tar but I don't see what difference that should make. Given that cpanel backups (provided as tar.gz archives of the home directory) include mail/ and seem to be copies of the filesystem at a particular time (though not true "snapshots" as such), aren't these just as "safe" as an rsync-ed backup? Can anyone confirm/deny/shed any light on the issue(s), if indeed any? Many thanks, Gareth

last_login using fs:posix does not autocreate the last-login directory
by karl＠denninger.net 13 Aug '23

13 Aug '23

I am using the last_login plug-in on a relatively small system to populate the last access time for users in the directory format. I don't want to have this go into an SQL database or similar as the userbase is small and shell access to the information for other purposes is useful. I have this in the conf.d directory under the configuration dir in 20-lastlogin.conf: protocol imap { mail_plugins = $mail_plugins last_login } plugin { last_login_dict = fs:posix:prefix=/var/run/dovecot/ } This works except that while the prefix is there the "last-login" directory under the prefix gets removed on restart (as you think it might) and I can't find an example of how to have it auto-created. This results in a bunch of logged errors until I re-create that working directory under the base. Am I missing something obvious?

sso / sharing authenticated sessions how does it work
by Marc 12 Aug '23

12 Aug '23

I am totally not experienced with setting up sso etc. I was wondering if/how it is possible to share an authenticated session between dovecot and the mail client with the webmail so a user does not need to login again.

Dovecot and Thunderbird 15
by Elise 10 Aug '23

10 Aug '23

Hi, I recently had some issues with Thunderbird 15 when removing e-mail. With my other mailclient Outlook I could without any issue. As I don't grand POP3 mail pickup, I disabled that in dovecot.conf #service pop3-login { # inet_listener pop3 { # address = 10.10.10.52 # } # inet_listener pop3s { # address = 10.10.10.52 # } #} Enabling the above and restarting Dovecot solved the issue. Is it TB related or do I overlook a config parameter? E.

Question about custom flags
by d.meister-braeuer＠heinlein-support.de 09 Aug '23

09 Aug '23

Hello all, RFC3501 describes among other things that custom flags can be set for mails. These can be allowed or forbidden in the server: "Servers MAY permit the client to define new keywords in the mailbox". When I am on our server, it also looks like dovecot basically allows this: a select INBOX FLAGS (\Answered \Flagged \Deleted \Seen \Draft $Forwarded Old $ITipAnalyzed $ITipProcessed Forwarded NonJunk $cl_1 $cl_2 $cl_3) OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft $Forwarded Old $ITipAnalyzed $ITipProcessed Forwarded NonJunk $cl_1 $cl_2 $cl_3 \*)] Flags permitted. The only option that goes in this direction is this one: mail_max_keyword_length But basically describes something else as well, if I see it correctly. Is there a way to prevent dovecot from giving custom flags, or what is the name of the parameter where you can set this? Best

Outlook not showing all email in inbox at random
by David Koski 08 Aug '23

08 Aug '23

I manage IT for a small office with about 10 workstations. Dovecot has been installed for years and is now at 2.3.4.1-5 (Debian). I just discovered that the user cannot see many emails in the inbox. I was alerted when email was not appearing to be coming in for many hours. Other users observed the same thing. On investigation, I noticed many inbox emails missing in the Outlook GUI from times past that were on the server. It appears to be a broken client (Outlook 2019) to me but troubleshooting has yielded no solid leads. The profile and OST files have been re-created many times with no change in outcome. Each time, the inbox does not synchronize about 40 most recent emails but does for the last one for the day before and many before that. It may well be an Outlook issue so I'm looking for information to work around an Outlook bug if necessary. Thunderbird works perfectly. Also, interestingly, I can copy email from Thunderbird (or move emails on the server) to a temporary directory form the inbox, then move them back and they will appear if I don't move too many at a time.

Application to automate mail-crypt plugin with user keys
by Benedikt Zumtobel 08 Aug '23

08 Aug '23

Hi everyone, I run a very small (about 10 users) mailserver setup with the mail-crypt plugin activated and wanted to transition from a global key setup to user keys. Since I couldn't find a satisfying solution to reencrypt mailboxes when users change their password I started writing a script that ended up being a small webservice giving users a simple selfservice portal to change their password. I consider it pretty much done by now and it's public on github. Maybe it's useful for somebody else. However its use case is very narrow since I initially wrote this just for myself. It does only support a Postgres user store for instance. The main reason, however, for this post is me wondering if anybody would bother to give me some feedback. Especially for the following aspects: I execute doveadm from within my application. The advantage is that I can keep the code very light (~650 lines of code) while at the same time don't have to care about the crypto stuff which I wouldn't dare trying anyways. The disadvantage of this approach is that I had to write a doveadm wrapper that needs the setuid bit to execute doveadm mailbox commands. I consider this a bit hacky but a better solution didn't come to my mind. Another aspect is the password that is being used to encrypt the private key. When creating a new user in the database I generate a unique salt. This salt is prefixed to the user's clear text password and the resulting string is run trough the sha3-512 hash function. The output is the mail_crypt_private_password. You find the project here: https://github.com/nonce9/pwch Criticism is welcome. Benedikt

doveadm fts lookup: Is "search query" documented anywhere?
by Graham Leggett 07 Aug '23

07 Aug '23

Hi all, According to the —help option for doveadm fts, there is a “lookup” option as follows: [root@aurora ~]# doveadm fts --help usage: doveadm [-Dv] [-f <formatter>] fts <command> [<args>] expand [-u <user>|-A] [-S <socket_path>] <search query> lookup [-u <user>|-A] [-S <socket_path>] <search query> optimize [-u <user>|-A] [-S <socket_path>] [<namespace>] rescan [-u <user>|-A] [-S <socket_path>] [<namespace>] tokenize [-u <user>|-A] [-S <socket_path>] <text> The option does not appear to be documented anywhere (eg https://doc.dovecot.org/3.0/man/doveadm-fts.1/) and “search query” doesn’t appear to be defined. Guessing that it might be just plain text, I tried searching for a known word, but this failed as follows: [root@aurora ~]# doveadm fts lookup -u test(a)example.com sweet Fatal: Unknown argument SWEET Anyone know?
