Thanks Timo, OK, I'll give that a try, I should point out that the Sieve filters are working as they should be for general delivery, outside of doveadm backup.

Userdb lookup problems
by Ken Wright 16 Feb '25

16 Feb '25

I finally got my new Dovecot 2.4 installation going to the point I can log in from Evolution, but for some reason it won't accept my password. Here are the pertinent sections from the dovecot.conf, 10-mail.conf, and dovecot-sql.conf.ext files: dovecot.conf: userdb sql { query = SELECT home, uid, gid FROM mailbox WHERE username = '%{user | username}' AND domain = '%{user | domain}' AND active= '1' 10-mail.conf: mail_driver = maildir #mail_home = %{home} mail_home = /var/vmail/%{user | domain }/%{user | username } mail_path = ~/mail mail_inbox_path = /var/vmail/%{user | domain}/%{user | username } mailbox_list_utf8 = yes namespace inbox { separator = / inbox = yes } dovecot-sql.conf.ext: driver = mysql connect = host=localhost dbname=postfixadmin user=postfixadmin password=hidden userdb_default_password_scheme = ARGON2I password_query = SELECT username AS username, password FROM mailbox WHERE username = '%{user | username }' AND active= '1' user_query = SELECT maildir, 2000 AS uid, 2000 AS gid FROM mailbox WHERE username = '%{user | username }' AND active= '1' iterate_query = SELECT username AS username FROM mailbox I hope someone can explain my horrible mistake!

v2.4 and fts-flatcurve configuration
by Felix Zielcke 16 Feb '25

16 Feb '25

Hi, I updated today to 2.4.0 and still have problems configuring fts- flatcurve. This is in my config: mail_plugins { fts = yes fts_flatcurve = yes } fts flatcurve { language de { default = yes } language en { } autoindex = yes } But it then fails to start with: doveconf: Error: Failed to get language de: Filter language=de unexpectedly not found (invalid userdb or -o override settings?) doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf: Failed to get language de: Filter language=de unexpectedly not found (invalid userdb or -o override settings?) If I comment out the language settings, then it starts. But a "doveadm fts rescan -A" fails with: doveadm(***): Error: fts: Failed to initialize backend 'flatcurve': languages settings: Invalid settings: No language { .. } defined doveadm(***): Error: fts not enabled for user's namespace INBOX How do I fix these 2 errors?

Dovecot v2.4.0 released
by Aki Tuomi 16 Feb '25

16 Feb '25

Hi all, after a very long wait we are finally happy to release Dovecot v2.4.0! Some IMPORTANT things to notice: - We have changed the signing key for 2.4 going forward, releases are signed with EF0882079FD4ED32BF8B23B2A1B09EF84EDC5219, which can be found at https://repo.dovecot.org/DOVECOT-REPO-GPG-2.4 and is signed with the previous key. The old key has been renamed to https://repo.dovecot.org/DOVECOT-REPO-GPG-2.3. - New 2.4 packages **are not** compatible with old 2.3 configuration, please carefully review https://doc.dovecot.org/2.4.0/installation/upgrade/2.3-to-2.4.html before installing the new packages. - We are happy to provide experimental arm64 support in the form of a Docker image. - Docker images are now ran rootless, with UID 1000 as vmail using built sources. Please take this into consideration when upgrading. Latest 2.3 image can be used with tag 2.3-latest, if you are not ready for this change. We won't be sending separate mail about Pigeonhole anymore as we will release one anyways when we release Dovecot, and Pigeonhole versioning has been changed to match Dovecot versioning. Source codes available at - https://www.dovecot.org/releases/2.4/dovecot-2.4.0.tar.gz - https://www.dovecot.org/releases/2.4/dovecot-2.4.0.tar.gz.sig - https://pigeonhole.dovecot.org/releases/2.4/dovecot-pigeonhole-2.4.0.tar.gz - https://pigeonhole.dovecot.org/releases/2.4/dovecot-pigeonhole-2.4.0.tar.gz… Binary packages in https://repo.dovecot.org/ Docker images in https://hub.docker.com/r/dovecot/dovecot Kind regards, Aki Tuomi Open-Xchange oy --- Dovecot Core NEWS ----------------- * config: dovecot_config_version must be the first non-comment line in configuration file. * config: dovecot_storage_version must be in the configuration file. * config: Many configuration options have changed so old configuration files do not work without rewrite.
