variable expansion allowed in 'listen' config not working
by publists＠emailgroups.net 20 Sep '25

20 Sep '25

Hi, In a new dovecot 2.4 config I'm setting up a inet_listener for a service. I want to use an env var in `listen` expansion, like service imap-login { inet_listener imaps { listen = %{env:LAN_IPv4}, 127.0.0.1 } } This https://doc.dovecot.org/2.4.1/core/settings/variables.html says "You can use special variables in several places: All settings, except of type String without variables." Reading https://doc.dovecot.org/2.4.1/core/summaries/settings.html#listen `listen` directive allows listen Default *, :: Value IP addresses Unlike, for example deliver_log_format Default msgid=%{msgid}: %{message} Value String without variables which would be disallowed for "String without variables" I CAN use env vars across almost all of my config. But launch systemctl start dovecot fails with dovecot[17358]: Fatal: service(imap-login) Can't resolve address %{env:LAN_IPv4}: Name or service not known OTOH replacing - listen = %{env:LAN_IPv4}, 127.0.0.1 + listen = 10.1.1.1, 127.0.0.1 solves the launch issue. Like I said it works in other stanzas. Am I configuring this right for `listen`? Thanks, Dave

dovecot and oauth2 on fedora42
by Alex 20 Sep '25

20 Sep '25

Hi, I have a fedora42 system with dovecot-2.3.21 and trying to configure oauth2 support for a client application called acymailing as part of joomla. I'm trying to follow the instructions here, but I don't understand why I would need to involve google as the provider. How do I create my own provider? I don't want to authenticate against google, but against my own user database inside of joomla. I can create a local user, if that makes it possible, but not sure how to create the local provider it seems to require. https://doc.dovecot.org/2.3/configuration_manual/authentication/oauth2/ Thanks, Alex Hi, I have a fedora42 system with dovecot-2.3.21 and trying to configure oauth2 support for a client application called acymailing as part of joomla.

Hi, We use Dovecot and Postfix for internal emails and keep aliases in an LDAP table. We have multiple sites, with some user mailboxes local to each. If user A and B are both in alias OurGroup, and a message is sent to [ mailto:ourgroup@domain.com | ourgroup(a)domain.com ] [ mailto:a@domain.com | a(a)domain.com ] and [ mailto:b@domain.com, | b(a)domain.com, ] a and b will receive two copies of the message. Should this be addressed with Postfix or Dovecot? thanks Hi, We use Dovecot and Postfix for internal emails and keep aliases in an LDAP table.

fts_flatcurve max_term_size config missing or broken in v2.4
by publists＠emailgroups.net 17 Sep '25

17 Sep '25

Hi, I'm working on migrating my v2.3 -> v2.4 configuration. From my 2.3 config I have ... fts flatcurve { commit_limit = 2000 29 max_term_size = 60 min_term_size = 3 substring_search = yes } ... From reading the current docs' "Configuration Example" https://doc.dovecot.org/2.4.1/core/plugins/fts_flatcurve.html#configuration… that looks OK for v2.4.1 too. But a config check fails, doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/50-fts.conf line 29: max_term_size: Unknown setting: max_term_size (fts_max_term_size or fts_flatcurve_max_term_size not found either.) There's no mention of "max_term_size" in https://doc.dovecot.org/2.4.1/installation/upgrade/2.3-to-2.4.html as a change. It's also NOT listed as a current setting at https://doc.dovecot.org/2.4.1/core/summaries/settings.html Checking in code sources cd dovecot git checkout release-2.4.1 Switched to branch 'release-2.4.1' Your branch is up to date with 'origin/release-2.4.1'.
