Re: Problem email client iPhone ios18.2

Timo confirmed this type of message (see below) breaks iOS mail clients regardless of the IMAP server used. So it is almost certainly a client issue. We are in contact with the Apple Mail developers and have provided this debug information to them. michael > On 02/10/2025 7:19 AM MST Timo Sirainen via dovecot <dovecot(a)dovecot.org> wrote: > > > On 10.

I was able to solve the problem by replacing 'pattern' in 'dict_map' configuration with 'value'. With the following config the last_login table in mysql is getting filled as expected: last_login { dict proxy { name = sql } key = last-login/%{service}/%{user}/%{remote_ip} precision = ms } dict_server { dict sql { sql_driver = mysql mysql sql.example.com { dbname = mails user = dovecot password = pass } dict_map shared/last-login/$service/$user/$remote_ip { sql_table = last_login value_field last_access { type = uint } key_field userid { value = $user } key_field service { value = $service } key_field last_ip { value = $remote_ip } } } } The example in the dovecot documentation should be updated accordingly.

How do I enable the CDB backend in Dovecot 2.4.1? → “auth: Fatal: Unknown passdb driver ‘cdb’”
by Brent Clark 16 Jun '25

16 Jun '25

Good day everyone, I’m trying to authenticate against a constant database (CDB) file. After reading the /cdb_path/ description in the 2.4.1 manual (⟨https://doc.dovecot.org/2.4.1/core/summaries/settings.html#cdb_path⟩ <https://doc.dovecot.org/2.4.1/core/summaries/settings.html#cdb_path%E2%9F%A9>) I added the following to the conf file.: |passdb cdb { cdb_path = /srv/mail/passwd.cdb } userdb cdb { cdb_path = /srv/mail/passwd.cdb } | But dovecot says |auth: Fatal: Unknownpassdb driver 'cdb'| dovecot --version 2.4.1-4+debian11 (7d8c0e5759) I cant see anything in the changelogs. Is the “cdb” driver still available in 2.4.1, or was it renamed/removed? Any pointers (or a minimal working example) would be greatly appreciated.

Why would "doveadm mailbox" check certificate file access?
by Ralph Seichter 15 Jun '25

15 Jun '25

The following came as a nasty surprise while testing Dovecot 2.4.1-4: alice@host $ doveadm mailbox list -u $(whoami) doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf line 61: cert_file: open(/path/to/cert.pem) failed: Permission denied Unprivileged user Alice does not have access to cert.pem, nor does she need it. Calling "doveadm flags ..." causes the same error. I suspect other subcommands are affected as well, but did not test it. The technical reason might be that dovecot.conf is parsed for each doveadm invocation? In any case, the certificate access check for subcommands like "flags" or "mailbox" seems like a bug to me. -Ralph

Migrating to Docker 2.4.1 not show Mailbox elements
by alberto 15 Jun '25

Hi, I'm migrating my physical Dovecot Server 2.2.33.2 to a new 2.4.1 (latest) on Docker container installation. I've got auth process successfully (Mariadb + Wforce included), but I cannot see their Maildir mailbox structure and elements, and logging debug not show errors related. I detected in my probe account that when I make logging with the new installation, a new "Maildir" directory into Mailbox structure disk is created, as unique difference that I noted, and perhaps would be a symptom, but I'm not sure. ... imap(probe@mydomain)<20><BpSIoIY3GIpYDjFl>: Info: Mailbox INBOX: Mailbox created ... --- "probe@mydomain" account disk structure --- drwxrwsr-x 7 mail dovecot 4096 dic 19 09:33 .. drwx--S--- 3 dovecot dovecot 4096 jun 14 13:40 Maildir drwxrwsr-x 2 dovecot dovecot 4096 jun 13 20:12 tmp drwxrwsr-x 2 dovecot dovecot 4096 jun 14 12:42 new drwxrwsr-x 2 dovecot dovecot 16384 jun 14 12:47 cur drwx--S--- 3 dovecot dovecot 4096 jun 3 16:02 sieve drwxrwsr-x 5 dovecot dovecot 4096 jun 14 12:57 .Sent drwxrwsr-x 5 dovecot dovecot 4096 nov 9 2020 .spam drwxrwsr-x 5 dovecot dovecot 4096 abr 30 2019 .Drafts drwxrwsr-x 5 dovecot dovecot 4096 jun 14 12:47 .Trash -rw------- 1 dovecot dovecot 212 jul 28 2019 .dovecot.svbin -rw-rw-r-- 1 dovecot dovecot 656 feb 11 02:09 dovecot.index -rw-rw-r-- 1 dovecot dovecot 31832 jun 14 12:47 dovecot.index.cache -rw-rw-r-- 1 dovecot dovecot 26252 jun 14 12:57 dovecot.index.log -rw-rw-r-- 1 dovecot dovecot 7420 ene 16 14:32 dovecot.list.index.log -rw-rw-r-- 1 dovecot dovecot 29 may 4 2019 dovecot-acl-list -rw-rw-r-- 1 dovecot dovecot 10 oct 31 2020 dovecot-keywords -rw------- 1 dovecot dovecot 240 dic 26 16:37 dovecot.mailbox.log -rw------- 1 dovecot dovecot 8 dic 26 16:37 dovecot-uidvalidity -r--r--r-- 1 dovecot dovecot 0 abr 19 2019 dovecot-uidvalidity.5cb9d075 -rw-rw-r-- 1 dovecot dovecot 909 jun 13 20:12 dovecot-uidlist -rw-rw-r-- 1 dovecot dovecot 87 dic 26 16:37 subscriptions --- old other account disk structure --- drwxrwsr-x 7 mail dovecot 4096 dic 19 09:33 .. drwxrwsr-x 2 dovecot dovecot 4096 oct 8 2024 tmp drwxrwsr-x 2 dovecot dovecot 4096 oct 8 2024 new drwxrwsr-x 2 dovecot dovecot 4096 oct 8 2024 cur drwx--S--- 3 dovecot dovecot 4096 may 27 23:38 sieve drwxrwsr-x 5 dovecot dovecot 4096 abr 2 15:37 .Sent drwxrwsr-x 5 dovecot dovecot 4096 may 26 17:03 .spam drwxrwsr-x 5 dovecot dovecot 4096 abr 30 2019 .Drafts drwxrwsr-x 5 dovecot dovecot 4096 sep 4 2020 .Trash lrwxrwxrwx 1 dovecot dovecot 23 may 4 2019 .dovecot.sieve -> sieve/managesieve.sieve -rw------- 1 dovecot dovecot 264 may 5 2019 .dovecot.svbin -rw-rw-r-- 1 dovecot dovecot 816 oct 17 2019 dovecot.index -rw-rw-r-- 1 dovecot dovecot 30152 abr 2 15:35 dovecot.index.log -rw-rw-r-- 1 dovecot dovecot 30884 abr 2 15:35 dovecot.index.cache -rw-rw-r-- 1 dovecot dovecot 146 may 3 2019 dovecot.index.thread -rw-rw-r-- 1 dovecot dovecot 13 may 2 2019 dovecot-keywords -rw-rw-r-- 1 dovecot dovecot 240 oct 17 2019 dovecot.mailbox.log -rw------- 1 dovecot dovecot 8 oct 17 2019 dovecot-uidvalidity -rw-rw-r-- 1 dovecot dovecot 1773 oct 8 2024 dovecot-uidlist -rw-rw-r-- 1 dovecot dovecot 54 oct 17 2019 subscriptions This is my new Docker installation config: #

BUG: extra_groups doesn't accept multiple values
by m＠sacha.pl 14 Jun '25

14 Jun '25

Hello, I'm reporting a bug in the config processor/parser. The option extra_groups does not accept multiple (list) values. If you put a section like: service auth-worker { user = $default_internal_user group = $default_internal_group extra_groups = shadow mail } you will get the error message like: dovecotFatal: service(auth-worker) Group doesn't exist: shadow mail (See service auth-worker { extra_groups } setting) It is trivial to reproduce - just try to run the dovecot with the section like above, and you will get the error. Best regards, Marcin

Dovecot and xoauth2: oauth2 active_attribute check failed
by Markus Grandpré 14 Jun '25

14 Jun '25

Dear dovecot list members, I am currently working on the task of implementing an MFA solution with OpenID for our SOGo server v5.12.1.20250612-1 and our Dovecot server v2.3.21.1. For this purpose, we are using a Shibboleth IDP v5.1.4 with the appropriate OpenID extension via XOAUTH2. In my opinion, authentication and autorization requests and responses between SOGo and the IDP are working flawlessly, and with: SOGoSMTPAuthenticationType = xoauth2; NGImap4AuthMechanism = xoauth2; the SOGo server forwards the received access token to the Dovecot server. On the Dovecot side, I have configured the server as follows: /etc/dovecot/conf.d/10-auth.conf: disable_plaintext_auth = yes auth_username_format = %Ln auth_master_user_separator = * auth_mechanisms = plain login auth_verbose = yes auth_verbose_passwords = no auth_debug = yes auth_debug_passwords = yes mail_debug = yes verbose_ssl = yes !include auth-master.conf.ext !include auth-oauth2.conf.ext /etc/dovecot/conf.d/auth-oauth2.conf.ext auth_mechanisms = $auth_mechanisms plain xoauth2 oauthbearer passdb { driver = oauth2 mechanisms = xoauth2 oauthbearer args = /etc/dovecot/dovecot-oauth2.conf.ext } userdb { driver = static args = uid=vmail gid=vmail home=/var/vmail/%u } service auth { unix_listener /var/spool/postfix/private/auth { mode = 0660 # Assuming the default Postfix user and group user = postfix group = postfix } } /etc/dovecot/dovecot-oauth2.conf.ext introspection_mode = post introspection_url = https://<ID>>:<SECRET>@idp-test.uni-konstanz.de/idp/profile/oauth2/introspection username_attribute = mail tls_ca_cert_file = /etc/ssl/certs/ca-certificates.crt active_attribute = active active_value = true As soon as the SOGo server contacts the Dovecot server, and the latter contacts the IDP server, I see the following error message in the Dovecot server logs: Jun 13 11:44:47 bamenda dovecot: auth: Debug: http-client[1]: request [Req7: POST https://idp-test.uni-konstanz.de/idp/profile/oauth2/introspection] Free (requests lef t=1) Jun 13 11:44:47 bamenda dovecot: auth: Debug: oauth2(pop519315,134.34.240.55,<kMaO5XA3FrWGIvA3>): Introspection succeeded Jun 13 11:44:47 bamenda dovecot: auth: Debug: oauth2(pop519315,134.34.240.55,<kMaO5XA3FrWGIvA3>): Processing field active Jun 13 11:44:47 bamenda dovecot: auth: Debug: oauth2(pop519315,134.34.240.55,<kMaO5XA3FrWGIvA3>): oauth2 active_attribute check failed: expected active="true" but got "false" Jun 13 11:44:47 bamenda dovecot: auth: oauth2(pop519315,134.34.240.55,<kMaO5XA3FrWGIvA3>): oauth2 failed: Introspection failed: Provided token is not valid Jun 13 11:44:47 bamenda dovecot: auth: Debug: oauth2(pop519315,134.34.240.55,<kMaO5XA3FrWGIvA3>): Finished passdb lookup Jun 13 11:44:47 bamenda dovecot: auth: Debug: auth(pop519315,134.34.240.55,<kMaO5XA3FrWGIvA3>): Auth request finished Is the error on the IDP side, or is there something wrong with my Dovecot configuration, or both? How can I make Dovecot more verbose the way I could see all the tokens exchanged with SOGo and IDP? I would greatly appreciate your help.

dovecot-2.4 problems with uid/gid and mbox settings
by "Tóth Attila" 14 Jun '25

14 Jun '25

1. I have a disturbing uid/gid issue: up until dovecot-2.3, dovecot changed its uid/gid to the user it is delivering the mail for. I'm the first user on the system with uid 1000 and the users gid is 100. Therefore I kept first_valid_uid = 1000 and first_valid_gid = 100. Now that I've upgraded to dovecot-2.4, it immediately started to complain about unable to change uid/gid, because it tries to write in user's directory as mail:mail. Mail directories and files in it are accessible only by the owner, not even by the group. So even after lowering first_valid_uid/gid, the operation fails. Are there any configuration options to restore dovecot-2.3 behavior to change uid:gid to the actual user Jun 8 21:40:52 server dovecot: imap(user)<48978><1LgipBQ3LO1/AAAB>: Error: mkdir(/home/user/mail/.imap) failed: Permission denied (euid=8(mail) egid=12(mail) missing +x perm: /home/user/mail, dir owned by 1000:100 mode=0700) Jun 8 21:40:52 server dovecot: imap(user)<48978><1LgipBQ3LO1/AAAB>: Error: mkdir(/home/user/mail/.imap) failed: Permission denied (euid=8(mail) egid=12(mail) missing +x perm: /home/user/mail, dir owned by 1000:100 mode=0700) 2. I know, that mbox is deprecated as of dovecot-2.4 - or that it has been long superseded by more modern formats, but I have a setup for 20+ years (without any problems and less files) and before I would convert it to Maildir, I'd rather provide a transition period and keep using mbox for a little while. During dovecot-2.3 times this was my mail_location setting: mail_location = mbox:~/mail/:INBOX=/var/spool/mail/%u Mails get delivered into /var/spool/mail/user and when dovecot reads them, they get copied under /home/user/mail. Now for dovecot-2.4 I'm forced to came up with this: mail_driver = mbox mail_path = /home/%{user}/mail mail_inbox_path = /var/spool/mail/%{user} #mail_home Are there anyone else with a setup like this struggling with dovecot-2.4?
