Hello, I am trying to configure last-login plugin for dovecot 2.4.1 and getting the following error. doveconf -n # 2.4.1-4 (7d8c0e5759): /etc/dovecot/dovecot.conf # Pigeonhole version 2.4.1-4 (0a86619f) doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/30-lastlogin.conf line 24: pattern: Unknown setting: pattern (dict_map_key_field_pattern or dict_map_key_field_service_pattern not found either.)

After updating gettext to 0.24.1 our daily build of git head is now generating this error: ---------------------------------------- autoreconf -fiv .... configure.ac:266: warning: macro 'AM_ICONV' not found in library autoreconf: running: /usr/bin/autoconf --force configure.ac:266: error: possibly undefined macro: AM_ICONV If this token and others are legitimate, please use m4_pattern_allow.

I scanned the gettex mail lists but didn't spot anything that seemed relevant. Thanks for any guidance. -- Gene

Hello, if I try to retrieve crypt_private_key_file from userdb/ldap doesn't work, infact if I have: crypt_global_private_key main{ crypt_private_key_password=secret crypt_private_key_file=/path/to/file } all is ok. If I want to have: crypt_global_private_key main{ crypt_private_key_password=secret crypt_private_key_file= } userdb ldap { driver = ldap ..... fields { mail_crypt_global_private_key/main/crypt_private_key_file=inline:%{ldap:key} } } I have into logs: lmtp(134879): Fatal: Raw user initialization failed: mail_crypt_plugin: nuovo: Couldn't parse private key : Unknown key format I am sure that the key is correctly base64 encoded, infact if I pick the ldap value of %{ldap:key} and I decode base64 I have the pkey crypted key. Any suggestion?

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

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 ...)
