LDAP AD Quota override not working
by wt.forsaken＠gmail.com 26 Feb '26

Hi there, I'm testing the new version of Dovecot 2.4 in Debian 13 before upgrading to my customers and I'm having difficult on trying to override the user's quota. The LDAP base is from Samba4 AD and having been trying the following configuration: auth-ldap.conf.ext: ldap_uris = ldap://localhost ldap_auth_dn = cn=admin,dc=localdomain ldap_auth_dn_password = password ldap_base = ou=users, dc=localdomain passdb ldap { filter = (&(objectClass=person)(sAMAccountName=%{user})) bind = yes fields { userdb_quota_storage_size = %{ldap:telephoneNumber}B } } userdb prefetch { driver = prefetch } userdb ldap { fields { quota_storage_size = %{ldap:telephoneNumber}B } } 90-quota.conf mail_plugins { quota = yes } quota "User quota" { } quota_storage_size = 40M Since there is no quotaBytes in Samba AD, I'm testing to map the telephoneNumber parameters to override the quota, also I'm just testing a 40M to see how it works. Roundcube webmail can see the quota being overriden in its inferior bar, but when I send an email to the user which is above the quota, the journal log inform "failed to store into mailbox 'INBOX': Quota exceeded (mailbox for user is full)". I don't know how to override the quota, since in passdb section I used the "userdb_" prefix but it is not being passed to userdb when I input the "doveadm user ..." command. I don't know if I have been clear in my request, but I'd appreciate any help.

doveadm sync issue
by Dan Whitehouse 06 Nov '25

06 Nov '25

Hi, I am running Dovecot on Debian trixie (dovecot-core/stable,now 1:2.4.1+dfsg1-6 amd64). Under the previous version, which I believe was 2.3, I was able to run a sync script with the following syntax: doveadm sync -u <user> remote:<user>@<host.tld> This worked very well and I was able to sync my mail. Having upgraded, this syntax produces the following error: dsync-server: invalid option -- ‘U' Error: doveadm: Unexpected or incomplete option: -U Even though my script doesn’t pass “-U” explicitly I believe that it is passed internally: https://github.com/dovecot/core/blob/main/src/doveadm/doveadm-settings.c#L1… core/src/doveadm/doveadm-settings.c at main · dovecot/core github.com Confusingly the online help still displays: doveadm dsync-server —help doveadm dsync-server [-r <rawlog path>] [-T <timeout secs>] [-U] Here we can see that the “-U” option (despite all the above) appears to have been removed from the code: https://github.com/dovecot/core/commit/4c04e4c30fd4817a8b0e11d04d9681173f69… global: Remove replicator · dovecot/core@4c04e4c github.com I have added the following to /etc/dovecot/local.conf: dsync_remote_cmd = "ssh -l%{login} %{host} doveadm dsync-server -u%{user}” (Note that I override the “-U”) and sync once again works properly. Many thanks for your attention, Dan Whitehouse

Dovecot 2.4.0: Error with Oauth2 login after successful introspection
by sukanyamorbale＠gmail.com 31 Oct '25

31 Oct '25

Hello, I upgraded Dovecot from version 2.3.21 to 2.4.0. In version 2.3.21, I encountered issues with OAuth2 authentication that had worked correctly in earlier releases. Specifically, the active_attribute check was failing, even though Keycloak was sending the active value as true. After upgrading to Dovecot 2.4.0, the active attribute is now validated successfully, and token introspection completes as expected. However, I am now encountering the following error: 2025-10-30 14:43:41.438 Oct 30 13:43:41 auth: Panic: file expansion-statement.c: line 30 (var_expand_execute_stmt): assertion failed: (value != NULL) 2025-10-30 14:43:41.444 Oct 30 13:43:41 auth-worker(354): Debug: conn unix:auth-worker (pid=113,uid=101): Disconnected: Connection closed (fd=-1) 2025-10-30 14:43:41.443 Oct 30 13:43:41 auth: Error: Raw backtrace: #0 test_subprocess_fork[0x7f03870fc510] -> #1 backtrace_append[0x7f03870fc7c0] -> #2 backtrace_get[0x7f03870fc960] -> #3 event_filter_match_iter_init[0x7f0387106bc0] -> #4 i_syslog_fatal_handler[0x7f0387106d00] -> #5 i_panic[0x7f0387033c8e] -> #6 [unw_get_proc_name() failed: -10] -> #7 var_expand_program_execute[0x7f0387070460] -> #8 settings_file_get[0x7f0387083550] -> #9 settings_parse_keyidx_value_nodup[0x7f0387085660] -> #10 settings_parse_keyidx_value_nodup[0x7f0387085d70] -> #11 settings_parse_keyidx_value_nodup[0x7f0387087180] -> #12 settings_get[0x7f03870877b0] -> #13 auth_worker_auth_request_new[0x558c60949050] -> #14 auth_worker_auth_request_new[0x558c609496e0] -> #15 oauth2_json_tree_build[0x7f03870432f0] -> #16 oauth2_json_tree_build[0x7f03870433d0] -> #17 oauth2_request_parse_json[0x7f03870435a0] -> #18 http_client_request_callback[0x7f0387091ee0] -> #19 http_client_connection_lost_peer[0x7f0387094850] -> #20 http_client_peer_connection_failure[0x7f038709a090] -> #21 io_loop_call_io[0x7f0387122780] -> #22 io_loop_handler_run_internal[0x7f0387123aa0] -> #23 io_loop_handler_run[0x7f0387123c40] -> #24 io_loop_run[0x7f0387123e40] -> #25 master_service_run[0x7f0387075720] -> #26 main[0x558c60931e80] -> #27 __libc_init_first[0x7f0386dc9150] -> #28 __libc_start_main[0x7f0386dc9200] -> #29 _start[0x558c609323d0] Here is my current dovecot.conf. dovecot_config_version = 2.4.0 dovecot_storage_version = 2.4.0 protocols = imap pop3 lmtp auth_mechanisms { oauthbearer = yes xoauth2 = yes } oauth2 { introspection_url = https://client-name:client-key@iam.keyclock-url.com/auth/realms/realm-name/… introspection_mode = post active_attribute = active active_value = true username_attribute = preferred_username } userdb static { fields { uid = vmail gid = vmail home = /home/vmail/%{user | domain}/%{user | username} } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { mode = 0600 user = postfix group = postfix } } service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 user = postfix group = postfix } unix_listener auth-userdb { mode = 0600 user = vmail } user = dovecot } service auth-worker { user = vmail } log_debug = category=auth auth_verbose = yes auth_debug_passwords = yes mail_driver = maildir mail_home = /home/vmail/%{user | domain}/%{user | username} mail_path = ~ ssl_server_cert_file = /etc/ssl/private/vmail.crt ssl_server_key_file = /etc/ssl/private/vmail.key ssl_server_dh_file = /etc/dovecot/dh.pem mail_debug = yes log_path = /dev/stdout info_log_path = /dev/stdout debug_log_path = /dev/stdout Regards, Sukanya Morbale

You can find some more discussion at https://github.com/slusarz/dovecot-fts-flatcurve/issues/66, but I think the most important part (the very detailed analysis from Slusarz, thanks again!) might be enough to understand and maybe fix the problem.

Dovecot and Pigeonhole v2.4.2 released
by Aki Tuomi 31 Oct '25

31 Oct '25

Hi! We are pleased to release version 2.4.2 of Dovecot and Pigeonhole. Important notice that we are adding new dependency of libpcre2 in this release to implement support for regular expressions in more safe manner. This release adds support for Debian Trixie and Red Hat Enterprise Linux 10, and removes support for Debian Bullseye and Red Hat Enterprise Linux 8. https://dovecot.org/releases/2.4/dovecot-2.4.2.tar.gz https://dovecot.org/releases/2.4/dovecot-2.4.2.tar.gz.sig https://pigeonhole.dovecot.org/releases/2.4/dovecot-pigeonhole-2.4.2.tar.gz https://pigeonhole.dovecot.org/releases/2.4/dovecot-pigeonhole-2.4.2.tar.gz… Binary packages in https://repo.dovecot.org/ Docker images in https://hub.docker.com/r/dovecot/dovecot -- Dovecot NEWS * CVE-2025-30189: Passdb oauth2 (not oauth2 mechanism), passdb passwd, passdb bsdauth, and userdb passwd drivers would cause users to be cached with same cache key when auth cache was enabled. * auth: Remove proxy_always field. * config: Change settings history parsing to use python3. * doveadm: Print table formatter - Print empty values as "-". * imapc: Propagate remote error codes properly. * lda: Default mail_home=$HOME environment if not using userdb lookup * lib-dcrypt: Salt for new version 2 keys has been increased to 16 bytes. * lib-dregex: Add libpcre2 based regular expression support to Dovecot, if the library is missing, disable all regular expressions. This adds libpcre2-32 as build dependency. * lib-oauth2: jwt - Allow nbf and iat to point 1 second into future. * lib: Replace libicu with our own unicode library. Removes libicu as build dependency. * login-common: If proxying fails due to remote having invalid SSL cert, don't reconnect. + auth: Add ssl_client_cert_fp and ssl_client_cert_pubkey_fp fields, see https://doc.dovecot.org/latest/core/summaries/settings.html#ssl_peer_certif… for more information. + config: Add support for $SET:filter/path/setting. + config: Improve @group includes to work with overwriting their settings. + doveadm kick: Add support for kicking multiple usernames + doveadm mailbox status: Add support for deleted status item. + imap, imap-client: Add experimental partial IMAP4rev2 support. + imap: Implement support for UTF8=ACCEPT for APPEND + lib-oauth2, oauth2: Add oauth2_token_expire_grace setting. + lmtp: lmtp-client - Support command pipelining. + login-common: Support local/remote blocks better. + master: accept() unix/inet connections before creating child process to handle it. This reduces timeouts when child processes are slow to spawn themselves. - SMTPUTF8 was accepted even when it wasn't enabled. - auth, *-login: Direct logging with -L parameter was not working. - auth: Crash occured when OAUTH token validation failed with oauth2_use_worker_with_mech=yes. - auth: Invalid field handling crashes were fixed. - auth: ldap - Potential crash could happen at deinit. - auth: mech-gssapi - Server sending empty initial response would cause errors. - auth: mech-winbind - GSS-SPNEGO mechanism was erroneously marked as not accepting NUL. - config: Multiple issues with $SET handling has been fixed. - configure: Building without LDAP didn't work. - doveadm: If source user didn't exist, a crash would occur. - imap, pop3, submission, imap-urlauth: USER environment usage was broken when running standalone. - imap-hibernate: Statistics would get truncated on unhibernation. - imap: "SEARCH MIMEPART FILENAME ENDS" command could have accessed memory outside allocated buffer, resulting in a crash. - imapc: Fetching partial headers would cause other cached headers to be cached empty, breaking e.g. imap envelope responses when caching to disk. - imapc: Shared namespace's INBOX mailbox was not always uppercased. - imapc: imapc_features=guid-forced GUID generation was not working correctly. - lda: USER environment was not accepted if -d hasn't been specified. - lib-http: http-url - Significant path percent encoding through parse and create was not preserved. This is mainly important for Dovecot's Lua bindings for lib-http. - lib-settings: Crash would occur when using %variables in SET_FILE type settings. - lib-storage: Attachment flags were attempted to be added for readonly mailboxes with mail_attachment_flags=add-flags. - lib-storage: Root directory for unusable shared namespaces was unnecessarily attempted to be created. - lib: Crash would occur when config was reloaded and logging to syslog. - login-common: Crash might have occured when login proxy was destroyed. - sqlite: The sqlite_journal_mode=wal setting didn't actually do anything. - Many other bugs have been fixed. -- Pigeonhole NEWS * lib-sieve: Use new regular expression library in core. * managesieve: Add default service_extra_groups=$SET:default_internal_group. + lib-sieve: Add support for "extlists" extension. + lib-sieve: regex - Allow unicode comparator. - lib-sieve-tool: sieve-tool - All sieve_script settings were overriden. - lib-sieve: storage: dict: sieve_script_dict filter was missing from settings. - sieve-ldap-storage: Fix compile without LDAP.

Not sure if this was intentional as we still check for >= lua5-1 != lua5-2 in m4/want_lua.m4 Thanks -- Eray

dovecot_config_version 2.4.2 -> error
by Genes Lists 30 Oct '25

Hi I would expect this to track the current version (i.e. 2.4.2) - would be good to accept 2.4.2 and later versions as they are released: doveconf line 9: Invalid dovecot_config_version: Currently supported versions are: 2.4.0 2.4.1 0.0.0 -- Gene

Hello, can you tell me, where to find documentation on the USER_PASSWORD environment variable? I do not find how to specify more than one user. Thanks and best regards, Hendrik
