bug report: "Corrupted transaction log file" PLUS request for improvement of the documentation about mmap_disable
by Patrick Cernko 20 May '25

20 May '25

Hello Dovecot developers, hello list, since more than two years we had occasional log messages like this: Error: Mailbox INBOX: Corrupted transaction log file /IMAP/mail/mailboxes/USER/mdbox/mailboxes/INBOX/dbox-Mails/dovecot.index.log seq 45532: Unexpected garbage at EOF (sync_offset=4856) Mostly I had to repair the affected mailbox manually after such events. Luckily I could prevent any data corruptions by using the healthy mailbox from the replication partner. Those errors occurred rather seldom (once a month) but started get more often. At the end of last year, they occurred about once a week for 800 users with up to 200 folders. The reporting process was always different, like the indexer, imapd, lmtpd, replicator or doveadm (on cmdline). It was obviously some sort of race-condition between the different processes accessing the index. I did not see any hints how to reproduce it. At the beginning of this year I started to debug this issue by adding debugging log output to our productive system, mostly in lib-index. I was hoping to find the cause of the issue and maybe even provide a patch to fix this. But about 5 weeks ago, I discovered, that the error can be simply avoided by setting mmap_disable=yes. Since this change, the error did not occur again even with specific tests, that previously likely triggered the bug. That's where I stopped to debug further. We are running Dovecot in master-master mode using replication plugin behind a Dovecot director setup. The storage on the backends is provided by local disks on Linux with newest ZFS filesystem. We use mdbox storage and FTS. While testing I also checked ext4 instead of ZFS and different FTS backends without success. I can provide more information for the developers if you are interested! --------------------------------- About mmap_disable: The documentation only mentions, that you should set this to "yes" for SHARED filesystems (I don't think local ZFS or ext4 qualify for that). https://doc.dovecot.org/2.3/settings/core/#core_setting-mmap_disable On another page (https://doc.dovecot.org/2.3/admin_manual/mailbox_formats/#memory-mapping) it is mentioned, that "If mmap() is supported by your filesystem, it’s still not certain that it gives better performance. Try benchmarking to make sure." I also found an old mail from Timo (https://dovecot.org/list/dovecot/2011-December/079975.html) which lists 3 cases, where mmap_disable=yes is required or at least suggested. In only one case, he wrote "With local filesystems mmap_disable=no _should_ be faster." I did not do extensive benchmarks but I did not see any performance issues since we disabled mmap on our IMAP backends. So, I wonder, if it would not be better to switch the default for mmap_disable to YES: 1. There are configurations, where the current default might cause data corruption! 2. There are configurations, where disabling mmap is suggested. 3. Even on local storage, the performance benefits are unsure. 4. According to my observations, even on local storage, enabling mmap can cause data corruption. Changing the default to NO would protect users from accidental data corruption. Users that aim for maximum performance can still enable mmap and test if it improves performance. IMHO the documentation should mention, that even for local disks, mmap CAN cause data corruption (until the above mentioned bug is found and fixed).

Hi. How can I patch the source code so that the server forces the list of all folders to be displayed in quotes? Or add the corresponding parameter to the configuration file? -- Best regards, Lafiel mailto:lafiel@elven.pw

Dovecot 3.21.1 -> 2.4.0 SegFault
by Cata S 19 May '25

19 May '25

Hi guys, There seems to be some issue with Dovecot deployed on alpine. More specifically, the dovecot.config file is not properly read. I have run some debugging and the SegFault is returned in the function below: #0 0x000055555556779b in config_parsed_get_setting () No symbol table info available. #1 0x0000555555563708 in config_dump_full () No symbol table info available. #2 0x000055555555c814 in main () No symbol table info available. This was also addressed by alpine here: https://gitlab.alpinelinux.org/alpine/aports/-/issues/17050 Any idea what could be causing this? Thanks for looking into it, Cata

Users losing mail from their mailboxes
by Nikolaos Milas 18 May '25

18 May '25

Hello, We are on Dovecot 2.3.18. Some users are occasionally complaining that all mail vanishes from their inbox. However, we cannot find any indication of deletions or expunge in the log. One explanation could be that mail files are deleted externally (at the file system level), but I can't imagine what could cause such deletions. How would you suggest us to troubleshoot this further? We could enable "mail_debug = yes", but this would flood the logs and cause performance drop, and the issue is happening rarely. Any other ideas to troubleshoot these cases in the past (through logs) or monitor (whatever) for the future? (The config is listed at the end.) Thanks in advance.

Problem with Dovecot on a FIPS enabled system

For additional modules, the mail_plugin_dir parameter is ignored
by Lafiel 14 May '25

14 May '25

Hi. The NixOS distribution for Dovecot uses a patch that hardcodes the path to the plugins in `/etc/dovecot/modules`. The modules themselves are located at `/nix/store/z9kf4ri8sq9f3r510qsm59g1n6kfc7q6-dovecot-2.3.21.1/lib/dovecot`, the script creates symlinks in the `/etc/dovecot/modules` directory. The additional modules are loaded normally. Now I want to remove the patch. I added the parameter `“--with-moduledir=$(out)/etc/dovecot/modules”`, and the modules are located at path `/nix/store/wb885d6w5dfchg9v481f55zj4a2p3r89-dovecot-2.3.21.1/etc/dovecot/modules`. In the configuration I added the parameter `mail_plugin_dir = /etc/dovecot/modules`. The main modules load fine, but the optional modules don't want to load: ``` Error: Plugin 'imap_sieve' not found from directory /nix/store/wb885d6w5dfchg9v481f55zj4a2p3r89-dovecot-2.3.21.1/etc/dovecot/modules ``` For additional modules, the mail_plugin_dir parameter is ignored. Temporary solution - in src/config/config-parser.h file I replaced the line ``` #define CONFIG_MODULE_DIR MODULEDIR"/settings” ``` by ``` #define CONFIG_MODULE_DIR “/etc/dovecot/modules/settings” ``` -- Best regards, Lafiel mailto:lafiel@elven.pw

Unable to save message in shared mailbox
by Markus Bach 12 May '25

12 May '25

Hello, I have a curious problem. We are running a Debian bookworm server with dovecot 2.3.19.1. We have a lot of shared mailboxes and most of them are behaving just fine. But we have a problem with one shared mailbox: Users aren't able to save messages in it even though they have the right to. This issue popped up, when a user This mailbox is set up like every other shared-mailbox, so I don't think it's a permission problem. We tried it with several users giving them the same access rights and always got an error when trying to save a mail in the shared mailbox. I didn't find anything that could help in the log files. Even after turning on `mail_debug` I can't even see the try to save a message in the logs. Some of the things I've tried so far without any success: * doveadm force-resync * increasing the quota for the shared-mailbox * disabling the quote for the shared-mailbox * recreating the Sent folder in the shared-maiblox. Does anybody have any idea how I can debug this further or where the issue could be?

Dovecot lifecycle announcement
by Aki Tuomi 12 May '25

12 May '25

We are announcing these Dovecot end-of-life (EOL) decisions: 1. All Dovecot versions before 2.3 are now fully EOL. We will not provide any additional patches, including security issues, for these releases. 2. For Dovecot CE 2.3 we will provide critical security bug fixes. Thus, if you are experiencing a non-security issue with Dovecot, we need you to upgrade into latest 2.4 CE release and reproduce the problem there in order for the team to debug. The Dovecot team will no longer debug non-security related issues for 2.3 releases. If the issue can occur with the latest 2.4 release, please file a bug report and we will take a look! If you are using a 2.3.x version packaged from an Operating System Vendor, please open a bug against them for fixing it. We do not provide patches or bug fixes against these OS Vendor specific releases. Dovecot CE 2.4.x is the current main release, which will continue to receive feature, bug and security patches. We accept bug reports against latest 2.4 version or "main" branch of Dovecot. Packages for Dovecot CE 2.4 can be found at https://repo.dovecot.org. Thank you for using Dovecot! Note: Users with a commercial agreement with Open-Xchange (Dovecot Pro) have a separate extended EOL policy, so this announcement does not apply to them. Regards, Aki Tuomi Open-Xchange oy

MySQL Auth Troubles during Migration to 2.4.1
by Odhiambo Washington 07 May '25

I am between a rock and a hard place while doing my migration from 2.3.19.1 to 2.4.1 I have setup a clean system to test the running before I import my database of virtual users. I haven't changed much from the config examples provided at My auth-sql.conf.ext: sql_driver = mysql mysql /var/run/mysqld/mysqld.sock { user = db_user password = XXXXX dbname = dbname } passdb sql { default_password_scheme = SHA512 query = SELECT crypt AS password FROM users,domains WHERE users.username = '%{user}' AND users.enabled = '1' AND users.type='local' and domains.enabled='1' and domains.domain_id = users.domain_id } userdb sql { query = SELECT pop as home, uid, gid FROM users WHERE username = '%{user}' iterate_query = SELECT username AS user FROM users } dovecot -n: ``` root@mail:/etc/dovecot/conf.d# doveconf -n # 2.4.1-4+debian12 (7d8c0e5759): /etc/dovecot/dovecot.conf # Pigeonhole version 2.4.1-4+debian12 (0a86619f) # OS: Linux 6.1.0-34-amd64 x86_64 Debian 12.10 # Hostname: mail.domain.name dovecot_config_version = 2.4.1 auth_debug_passwords = yes auth_verbose = yes auth_verbose_passwords = yes dovecot_storage_version = 2.4.1 fts_autoindex = yes fts_autoindex_max_recent_msgs = 999 fts_search_add_missing = yes info_log_path = /var/log/dovecot.log log_debug = category=auth mail_plugins { notify = yes mail_log = yes } protocols = imap pop3 lmtp sieve sql_driver = mysql mysql /var/run/mysqld/mysqld.sock { dbname = exim4u password = # hidden, use -P to show it user = exim4u } passdb sql { default_password_scheme = SHA512 query = SELECT crypt AS password FROM users,domains WHERE users.username = '%{user}' AND users.enabled = '1' AND users.type='local' and domains.enabled='1' and domains.domain_id = users.domain_id } userdb sql { iterate_query = SELECT username AS user FROM users query = SELECT pop as home, uid, gid FROM users WHERE username = '%{user}' } namespace inbox { inbox = yes mailbox Drafts { special_use = "\\Drafts" } mailbox Junk { special_use = "\\Junk" } mailbox Trash { special_use = "\\Trash" } mailbox Sent { special_use = "\\Sent" } mailbox "Sent Messages" { special_use = "\\Sent" } } service imap-login { inet_listener imap { } inet_listener imaps { } } service pop3-login { inet_listener pop3 { } inet_listener pop3s { } } service submission-login { inet_listener submission { } inet_listener submissions { } } service lmtp { unix_listener lmtp { } } service imap { } service pop3 { } service submission { } service auth { unix_listener auth-userdb { } } service auth-worker { } service dict { unix_listener dict { } } service managesieve-login { inet_listener sieve { port = 4190 } inet_listener sieve_deprecated { port = 2000 } } service managesieve { } ``` I ran a test against the POP3 daemon: ``` telnet 0 110 Trying 0.0.0.0...

Quota wrongfully reported as exceeded on shared mailbox
by adminkram＠tripelspark.de 07 May '25

07 May '25

Hi, I've been scratching my head without luck with the following problem: I've shared a mailbox from one user "COMPANY" to another user "JOE". Both users have quotas and both quotas are less than 50% used. When the user JOE tries to post a message into the shared folder, dovecot complains that the user would be over quota: bash# /usr/lib/dovecot/imap -u JOE 1 append shared/COMPANY/Sent/JOE {10} a NO [OVERQUOTA] Quota exceeded (mailbox for user is full) (0.057 + 0.000 + 0.057 secs). However, nobody is over quota: bash# doveadm quota get -u COMPANY Quota name Type Value Limit % User quota STORAGE 4754996 10485760 45 User quota MESSAGE 33695 - 0 bash# doveadm quota get -u JOE Quota name Type Value Limit % User quota STORAGE 14 1048576 0 User quota MESSAGE 3 - 0 Some more infos: 1. Dovecot-2.3.21 (+Debian updates) 2.3.21 (47349e2482) (NOTE: dovecot.org/mailing-lists says: Use dovecot –version to get it. The command is dovecot --version, though!) 2. I've performed "doveadm quota recalc" on both users, no change. 3. I've checked sharing ACL permissions, if I give just "l" permission, the response will be "NO [NOPERM] Permission denied". It does not seem to be an ACL permission reported wrongly. 4. I've tried increasing the quota size beyond reason (100 Gbytes for JOE), no change. 5. I've restarted dovecot after each change. 6. When trying to move a message into the shared Sent/joe folder in Thunderbird, same problem happens, Thunderbird displays the over quota message. Thunderbird cannot display the quota info for the shared folder, though. 7. I tried to enable rawlog (rawlog_dir in protocol imap). It does nothing helpful. It logs the manual commands from my pre-auth sessions (imap -u JOE) but it will stubbornly not log any commands issued by Thunderbird. ?! Any idea how to further debug this or what could be wrong? Thank you, Wolfgang

Dovecot 3.21.1 -> 2.4.0 SegFault
by Cata S 06 May '25

06 May '25

Hi guys, There seems to be some issue with Dovecot deployed on alpine. More specifically, the dovecot.config file is not properly read. I have run some debugging and the SegFault is returned in the function below: #0 0x000055555556779b in config_parsed_get_setting () No symbol table info available. #1 0x0000555555563708 in config_dump_full () No symbol table info available. #2 0x000055555555c814 in main () No symbol table info available. This was also addressed by alpine here: https://gitlab.alpinelinux.org/alpine/aports/-/issues/17050 Any idea what could be causing this? Thanks for looking into it, Cata

2.3 -> 2.4 migration problem(s)
by Kamil Jońca 06 May '25

06 May '25

Recently in debian sid version 2.4 appeared and I tried to migrate. it (mostly working) but Neither dovecot-lda nor doveadm does not see current system user context i.e. --8<---------------cut here---------------start------------->8--- %doveadm mailbox list Fatal: One of -u, -F, -A or --no-userdb-lookup must be provided --8<---------------cut here---------------end--------------->8--- from lda logs --8<---------------cut here---------------start------------->8--- Fatal: Namespace root: mail_storage settings: Failed to parse configuration: Invalid setting mail_path=~/Mail/0/: mail_path setting used home directory (~/) but there is no mail_home and userdb didn't return it --8<---------------cut here---------------end--------------->8--- for dovecot-lda setting "mail_home = /home/%{user|username}" helped but still ... doveadm mailbox list -u kjonca and "-d" option helped in both cases Moreover I found that doveadm does not work when dovecot is stoped (but used to work in 2.3.x) Another thing is: --8<---------------cut here---------------start------------->8--- deliver_log_format = msgid=%m: %$ --8<---------------cut here---------------end--------------->8--- in 2.3.x configuration it created line like this: --8<---------------cut here---------------start------------->8--- 2025-04-27T02:08:31.925845+02:00 alfa dovecot: LDA(kjonca): sieve: msgid=<fd248603-b186-4ee2-9e76-b9b9c0fe7a87@alfa>: fileinto action: stored mail into mailbox 'RSS' --8<---------------cut here---------------end--------------->8--- but now it does not work (what is strange I cannot find %$ description and %m is described as "mechanism" not message id ...)

You didn't copy and paste the whole context of this documentation comment: https://doc.dovecot.org/2.4.1/core/config/auth/caching.html#early-change When looking at the full context, this is a situation where a user is either using a password that isn't yet valid (= a bad password, so it's a valid denial), or the user did change their password but the Dovecot system doesn't see the change for some reason (= server/admin issue). In the above situation, doing a passdb lookup without waiting for cache TTL expiration is simply the same situation as not having a negative cache at all. So either don't use the negative cache or fix the password sync (and if you can't fix the authentication sync delay, you can't use a negative cache). An unlikely situation is that the user is using the wrong password originally, and then changes their password to this wrong password. You can always reduce the negative cache TTL if you want to catch this rare situation, at the cost of a lower cache hit rate more generally. michael

Authentication caching and password changes
by Diego Alvarez 03 May '25

03 May '25

In Dovecot docs (https://doc.dovecot.org/2.3/configuration_manual/ authentication/caching/) we see: 1. User logs in with password Y. The cached password X doesn’t match Y and the previous authentication was unsuccessful, so Dovecot doesn’t bother doing another backend passdb lookup (until cache TTL expires). The login fails. Anyone knows why they chose this design ? Why not simply do a passdb lookup instead of waiting for cache TTL to expire ?

(2.3->2.4) How to expunge with hierarhy saving?

GSSAPI authentication regression with 2.4.x
by Noah Meyerhans 02 May '25

02 May '25

While preparing the Debian packages of Dovecot 2.4.1, I encountered what appears to be a regression that impacts the ability of some clients to successfully negotiate gssapi/krb5 authentication. The regression has so far been observed in gsasl, which was able to successfully authenticate to 2.3.19 but cannot authenticate to 2.4.1. Mutt is able to successfully authenticate with 2.3.19 and 2.4.1. Doveconf output is attached. The debug logs for both failed (gsasl) and successful (mutt) authentications follow.

Dovecot 3.21.1 -> 2.4.0 SegFault
by Cata S 02 May '25

02 May '25

Hi guys, There seems to be some issue with Dovecot deployed on alpine. More specifically, the dovecot.config file is not properly read. I have run some debugging and the SegFault is returned in the function below: #0 0x000055555556779b in config_parsed_get_setting () No symbol table info available. #1 0x0000555555563708 in config_dump_full () No symbol table info available. #2 0x000055555555c814 in main () No symbol table info available. This was also addressed by alpine here: https://gitlab.alpinelinux.org/alpine/aports/-/issues/17050 Any idea what could be causing this? Thanks for looking into it, Cata
