[Patch] Allow sieve redirects to specified domains only
by Kadlecsik József 10 Aug '25

10 Aug '25

Hello, The use case is simple: we have to forbid sieve redirects to outside, but should be able to redirect inside. The patch below adds a new sieve configuration option sieve_allowed_redirects to list the domains to which redirects are permitted and otherwise are not allowed. Please consider it. diff --git a/pigeonhole/doc/example-config/conf.d/90-sieve.conf b/pigeonhole/doc/example-config/conf.d/90-sieve.conf index 238bcf4..3b4ac65 100644 --- a/pigeonhole/doc/example-config/conf.d/90-sieve.conf +++ b/pigeonhole/doc/example-config/conf.d/90-sieve.conf @@ -126,6 +126,10 @@ plugin { # script execution.

Dovecot fails to "initialize SSL server context"
by jaap＠jbril.net 04 Aug '25

04 Aug '25

I am configuring a new mailserver. Postfix works and is getting configured according to our wishes. Dovecot is more stubborn: for some reason I'm not able to understand, it refuses to "initialize SSL server context". complaining that "Can't load SSl Certificate". I believe I have configured the same certificate (and accompanying key) for imap-login that I use for https. But dovecot does not agree. I looked at error:14187180. All I found were errors on the configuration for the Certs cq Keys which I think I am avoiding . Two questions: Please correct me if I'm wrong. Can you clarify dovecot's error message? Jaap Server: * Rocky Linux 9.6 kernel 5.14.0-570.28.1 * Dovecot 2.3.21.1 * Openssl 3.2.2 * Certbot 3.1.0 Https is functioning as expected: ssl-config: * Include /etc/letsencrypt/options-ssl-apache.conf * SSLCertificateFile /etc/letsencrypt/live/radicale.camelopardus.nl/fullchain.pem * SSLCertificateKeyFile /etc/letsencrypt/live/radicale.camelopardus.nl/privkey.pem * ssl_cert = </etc/letsencrypt/live/iris.camelopardus.nl/fullchain.pem test from client: openssl s_client -connect radicale.camelopardus.nl:https reply: *CONNECTED(00000003)* *depth=2 C = US, O = Internet Security Research Group, CN = ISRG Root X1* *verify return:1* *depth=1 C = US, O = Let’s Encrypt, CN = E6* *verify return:1* *depth=0 CN = radicale.camelopardus.nl* *verify return:1* Dovecot responds differently (for Thunderbird as well as) for openssl: conf.d/10-ssl.conf: * ssl_cert = </etc/letsencrypt/live/radicale.camelopardus.nl/fullchain.pem * ssl_key = </etc/letsencrypt/live/radicale.camelopardus.nl/privkey.pem test: openssl s_client -connect radicale.camelopardus.nl:imaps reply: CONNECTED(00000003) write:errno=104 no peer certificate available For both there is the same error in dovecot's log: imap-login: Error: Failed to initialize SSL server context: Can't load SSL certificate (ssl_cert setting): error:14187180: SSL routines:ssl_do_config:bad value: section=system_default, cmd=Groups, arg=X25519:secp256r1:X448:secp521r1:secp384r1:ffdhe2048:ffdhe3072:ffdhe4096:ffdhe6144:ffdhe8192: user=<>, rip=2a10:3781:5ab:1:ff51:cbd1:4d54:fb7b, lip=2a10:3781:5ab:10::aaf,

migrate to virtual mailboxes before upgrading to 2.4
by roughnecks 04 Aug '25

04 Aug '25

Hello, I was thinking about, maybe, migrating my postfix/dovecot server to virtual mailboxes, before upgrading Debian to Trixie. So, atm, I have system users with ~/Maildir but it's not so convenient anymore. I am looking for some documentation/guide on how to migrate everything to virtual mailboxes. Of course I searched by myself, but didn't find many results. Thanks -- roughnecks

sieve script is not exescuted

I have scripts in 2 places: sieve_script personal { path = ~/.dovecot.sieve } sieve_script before { path = /etc/dovecot/sieve } /etc/dovecot/sieve is directory with (currently) one script. This script add header to message. And it seems, that "before" script is not executed. Any hints? KJ -- http://wolnelektury.pl/wesprzyj/teraz/ "Linux: the operating system with a CLUE...

"lock/disable" user's mailbox
by roughnecks 29 Jul '25

29 Jul '25

Hello, not sure if relevant here, but I'm in need of disabling or locking down an user's mailbox, without completely removing the related system account. It would be nice if said account was not able to receive emails anymore, or "better", until it was re-enabled. Would also be cool if the sender received a warning back, upon the failed dispatch. Does that even make sense? :D I'm running postfix and dovecot on a debian bookworm VPS. Thanks -- roughnecks

When does dovecot use sendmail_path?
by Joseph Tam 29 Jul '25

29 Jul '25

I'm trying to plug up all the holes where local mail leaves our mail system without a DKIM signature. One avenue is bounce messages. I wrote a small sendmail wrapper to add DKIM signatures, and defined it as the value for dovecot's sendmail_path. I presume Dovecot invokes this executable when it has to send a send message. Under what circumstances does this happen? I tried to provoke a mailout by sending messages to recipients with full quotas and permission locked mailbox files, but could not generate any mail back.

one-off doveadm commands broken in 2.4.1 when using docker
by jlh 28 Jul '25

28 Jul '25

Hi all In 2.3, I could use doveadm from the docker image as a standalone tool, but this no longer works in 2.4: $ docker run --rm -ti dovecot/dovecot:2.3-latest doveadm usage: doveadm [-Dv] [-f <formatter>] <command> [<args>] altmove [-u <user>|-A] [-S <socket_path>] [-r] <search query> [...snip...] $ docker run --rm -ti dovecot/dovecot:latest-2.4 doveadm doveconf: Fatal: Cannot expand variable %{env:USER_PASSWORD This was useful for hashing passwords with "doveadm pw". I assume this wasn't an intentional change in how doveadm works. For now I'll just use the old image when hashing passwords. Thank you! Jean-Luc

siebe settings in 2.4.0
by Helmut K. C. Tessarek 23 Jul '25

23 Jul '25

I've been reading the docs and the migration docs for hours, but the sieve config is a mess. In 2.3.x I am using: plugin { sieve = ~/.sieve sieve_dir = ~/.sieve_storage } and this is how it looks in my home dir: $ ls -la .sie* lrwxrwxrwx 32 a b c d .sieve -> .sieve_storage/MailFilters.sieve .rw------- 0 a b c d .sieve.log .rw------- 17,414 a b c d 2025-07-08 03:00 .sieve.svbin So How do I do the same in 2.4.x? I've come so far as: sieve_script personal { driver = file } But then there are path, bin_path, active_path, name, and a bunch of other settings. Sorry to be a little bit frustrated, but my old settings are not out of the ordinary (2 freaking parameters), but there is no documentation on how to migrate these 2 very simple settings to the new format. The upgrade docs explain the new var expansion and a matrix with old and new parameters. But this info is completely missing for sieve. The doc only points to "script storage". Really? You couldn't have added these 2 parameters to the old-new matrix? I am not asking you to do this for every single sieve parameter, but at least for the 2 or 3 most used ones. Sorry for my rant, but I had to get it out there to not go insane. Cheers, K. C. -- regards Helmut K. C.

Anyone have working examples of how one might go about *debugging* a userdb/passdb LUA script for authentication?
by Andy Baugh 22 Jul '25

22 Jul '25

Howdy, I've been working on upgrading the version cPanel ships to Dovecot 2.4. It appears that the "dict" driver for passdb/authdb has been removed per your documentation, with a recommendation to use a lua script instead. As such I've followed the online documentation to do so and wound up with a userdb/passdb section that looks like so: passdb cpauthd { driver = lua lua_file = /usr/local/cpanel/etc/dovecot/cpauthd.lua lua_settings { socket = /usr/local/cpanel/var/cpdoveauthd.sock } result_internalfail = continue result_failure = return-fail } userdb cpauthd { driver = lua lua_file = /usr/local/cpanel/etc/dovecot/cpauthd.lua } My prospective lua script only takes from the socket arg passed in and reads from the socket, delivering back the same kind of answer we would have previously got from the auth dict driver (converting password_key/user_key to auth_passdb/userdb_get_cache_key in script as appears to be suggested). Unfortunately, I'm thinking that this entire setup is being ignored, as when I do: doveadm -D -o auth_debug=yes auth lookup for a user I know to be valid on the system with the previous 2.3 setup, I don't even see any indication that the lua authentication database is even consulted. Jul 18 12:32:30 Debug: auth-master: passdb lookup(zippy(a)cptest.local): Started passdb lookup Jul 18 12:32:30 Debug: auth-master: conn unix:/var/run/dovecot/auth-userdb: Connecting Jul 18 12:32:30 Debug: auth-master: conn unix:/var/run/dovecot/auth-userdb (pid=800187,uid=0): Client connected (fd=9) Jul 18 12:32:30 Debug: auth-master: conn unix:/var/run/dovecot/auth-userdb (pid=800187,uid=0): auth input: Jul 18 12:32:30 Error: auth-master: passdb lookup(zippy(a)cptest.local): Auth PASS lookup failed Jul 18 12:32:30 Debug: auth-master: passdb lookup(zippy(a)cptest.local): auth PASS input: Jul 18 12:32:30 Debug: auth-master: passdb lookup(zippy(a)cptest.local): Passdb lookup failed Jul 18 12:32:30 Error: cmd auth lookup: passdb lookup failed for zippy(a)cptest.local Jul 18 12:32:30 Debug: auth-master: conn unix:/var/run/dovecot/auth-userdb (pid=800187,uid=0): Disconnected: Connection closed (fd=9) Similarly, in my lua script, I try to use the "dovecot.auth.log_debug/log_info" etc. functions in documentation within the scope of auth_passdb_lookup or auth_userdb_lookup, yet I never see any debug prints even if I add a debug line to the start of the function to indicate entry. What I would like to know is whether there is some debug flag I'm missing to see the routing from config -> lua script. Does this actually exist? I didn't see anything enlightening in the man pages or online documentation. Hopefully I'm just missing something simple.

dovecot internal auth cache expires soon
by Burn Zero 21 Jul '25

21 Jul '25

Hi, I am new to dovecot and I am trying to prepare a POC environment. I have dovecot installed with postfix to perform SASL authentication. I'm using postgresql as auth backend which is working fine. But I am facing an issue with dovecot's internal auth cache. The internal auth cache just expires in 5 minutes. There is only one login (it's me testing) and there are no other logins. OS version: Almalinux 10 Postfix: postfix-3.8.5-8.el10.x86_64 system memory: 4 GB CPU: 2 auth_cache_size = 10M auth_cache_ttl = 1800secs auth_cache_negative_ttl = 300secs ( I have tried this setting to 0 but it does not change anything ) Here's the dovecot -n: # 2.3.21 (47349e2482): /etc/dovecot/dovecot.conf # OS: Linux 6.12.0-55.9.1.el10_0.x86_64 x86_64 AlmaLinux release 10.0 (Purple Lion) # Hostname: localhostvm auth_cache_size = 10 M auth_cache_verify_password_with_worker = yes auth_debug = yes auth_mechanisms = plain login auth_verbose = yes login_log_format = %$: %s %f passdb { args = /etc/dovecot/conf.d/dovecot-sql.conf.ext driver = sql } protocols = service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } } ssl = required ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_cipher_list = PROFILE=SYSTEM ssl_key = # hidden, use -P to show it userdb { driver = prefetch } Here's the cache hit log: Jul 14 11:53:35 localhostvm postfix/submission/smtpd[107852]: connect from remote-server Jul 14 11:53:36 localhostvm dovecot[107739]: auth: Debug: client in: AUTH#0112#011LOGIN#011service=smtp#011nologin#011lip=192.168.100.12#011rip=192.168.100.25 Jul 14 11:53:36 localhostvm dovecot[107739]: auth: Debug: client passdb out: CONT#0112#011VXNlcm5hbWU6 Jul 14 11:53:36 localhostvm dovecot[107739]: auth: Debug: client in: CONT<hidden> Jul 14 11:53:36 localhostvm dovecot[107739]: auth: Debug: client passdb out: CONT#0112#011UGFzc3dvcmQ6 Jul 14 11:53:36 localhostvm dovecot[107739]: auth: Debug: client in: CONT<hidden> Jul 14 11:53:36 localhostvm dovecot[107739]: auth: Debug: sql(user(a)tld,192.168.100.25): Performing passdb lookup Jul 14 11:53:36 localhostvm dovecot[107739]: auth: Debug: sql(user(a)tld,192.168.100.25): cache hit: <hidden>#011user=user@tld Jul 14 11:53:36 localhostvm dovecot[107739]: auth: Debug: sql(user(a)tld,192.168.100.25): cache: validating password on worker Jul 14 11:53:36 localhostvm dovecot[107739]: auth-worker(107886): Debug: Loading modules from directory: /usr/lib64/dovecot/auth Jul 14 11:53:36 localhostvm dovecot[107739]: auth-worker(107886): Debug: Module loaded: /usr/lib64/dovecot/auth/lib20_auth_var_expand_crypt.so Jul 14 11:53:36 localhostvm dovecot[107739]: auth-worker(107886): Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_pgsql.so Jul 14 11:53:36 localhostvm dovecot[107739]: auth-worker(107886): Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_sqlite.so Jul 14 11:53:36 localhostvm dovecot[107739]: auth-worker(107886): Debug: sqlpool(pgsql): Creating new connection Jul 14 11:53:36 localhostvm dovecot[107739]: auth-worker(107886): Debug: sqlpool(pgsql): Creating new connection Jul 14 11:53:36 localhostvm dovecot[107739]: auth-worker(107886): Debug: conn unix:auth-worker (pid=107856,uid=97): Server accepted connection (fd=15) Jul 14 11:53:36 localhostvm dovecot[107739]: auth-worker(107886): Debug: conn unix:auth-worker (pid=107856,uid=97): Sending version handshake Jul 14 11:53:36 localhostvm dovecot[107739]: auth-worker(107886): Debug: conn unix:auth-worker (pid=107856,uid=97): auth-worker<1>: Handling PASSW request Jul 14 11:53:36 localhostvm dovecot[107739]: auth-worker(107886): Debug: conn unix:auth-worker (pid=107856,uid=97): auth-worker<1>: Finished Jul 14 11:53:36 localhostvm dovecot[107739]: auth: Debug: sql(user(a)tld,192.168.100.25): Finished passdb lookup Jul 14 11:53:36 localhostvm dovecot[107739]: auth: Debug: auth(user(a)tld,192.168.100.25): Auth request finished Jul 14 11:53:36 localhostvm dovecot[107739]: auth: Debug: client passdb out: OK#0112#011user=user@tld Jul 14 11:53:37 localhostvm postfix/submission/smtpd[107852]: 81GFE2083CH9: client=remote-server[192.168.100.25], sasl_method=LOGIN, sasl_username=user@tld I am not sure what is causing the cache to disappear in 5 min although I have set it to 1800s.

Building failures with 2.4.0 and 2.4.1 on MacOS: var_expand_crypt
by rmfuhrer＠optonline.net 18 Jul '25

18 Jul '25

I'm trying to build dovecot, both at tags 2.4.0 and 2.4.1, both failing with the same undefined-symbols link error. I've pulled the source from GitHub onto an Apple M2 Ultra Mac Studio running Sonoma 14.6.1. FWIW, I'm picking up various dependencies as packages from Homebrew via the CFLAGS and LDFLAGS args below. The prep steps before "make": $ ./autogen.sh $ CFLAGS="-I/opt/homebrew/include" LDFLAGS="-L/opt/homebrew/lib" ./configure --prefix=/opt/homebrew --with-bzlib --with-ldap --with-mysql --with-pam --with-sqlite --without-icu $ PATH="/opt/homebrew/opt/bison/bin:$PATH" make ... N.B.: The PATH tweak is solely intended to pick up a usable version (3.8.2) of bison, since the Xcode-supplied binary is too old (v2.3), and doesn't recognize certain cmdline flags. Also, getting even this far with 2.4.0 requires the "touch build-aux/config.rpath" workaround, and the 2-line patch to src/lib-http/http-server.h suggested on this thread: https://dovecot.org/mailman3/archives/list/dovecot@dovecot.org/thread/MFHSI…. Anyway, here's an excerpt of the build stdout/stderr. $ PATH="/opt/homebrew/opt/bison/bin:$PATH" make ... CCLD var_expand_crypt.la Undefined symbols for architecture arm64: "_binary_to_hex_append", referenced from: _var_expand_encrypt in var-expand-crypt.o _var_expand_encrypt in var-expand-crypt.o "_buffer_append", referenced from: _var_expand_crypt_settings in var-expand-crypt.o _var_expand_crypt_settings in var-expand-crypt.o "_buffer_append_c", referenced from: _str_append_c in var-expand-crypt.o ... ld: symbol(s) not found for architecture arm64 clang: error: linker command failed with exit code 1 (use -v to see invocation) make[3]: *** [var_expand_crypt.la] Error 1 make[2]: *** [all-recursive] Error 1 make[1]: *** [all-recursive] Error 1 make: *** [all] Error 2 $ Hopefully this is enough info to go on, but LMK if not.

Endless cycle of delete/expunge Outlook flagged messages.
by Mart Pirita 18 Jul '25

18 Jul '25

Hi, Suddenly I have a strange problem with the latest Outlook 365 (version 2506, build 16.0.1.18925.20076 64-bit) clients. When a user flags a message, they cannot remove the flag because Outlook gives an error message "The action cannot be performed because the message has been modified". One solution is to make the message unread and then remove the flag. However, since the moment a user flags a message for the first time, the maillog contains delete/expunge loop endlessly, for example: Jul 18 09:50:25 server dovecot: imap(user): delete: box=INBOX.Euro Brand, uid=2108, msgid=<GV1P195MB16414FAC3D4BAC6326F956048351A(a)GV1P195MB1641.EURP195.PROD.OUTLOOK.COM>, size=7597602, vsize=7698181, from="Masked User" <masked.user(a)somedomain.com>, subject=testing Jul 18 09:50:25 server dovecot: imap(user): expunge: box=INBOX.Euro Brand, uid=2108, msgid=<GV1P195MB16414FAC3D4BAC6326F956048351A(a)GV1P195MB1641.EURP195.PROD.OUTLOOK.COM>, size=7597602, vsize=7698181, from="Masked User" <masked.user(a)somedomain.com>, subject=testing Jul 18 09:50:27 server dovecot: imap(user): delete: box=INBOX.Euro Brand, uid=2109, msgid=<GV1P195MB16414FAC3D4BAC6326F956048351A(a)GV1P195MB1641.EURP195.PROD.OUTLOOK.COM>, size=7597628, vsize=7698214, from="Masked User" <masked.user(a)somedomain.com>, subject=testing Jul 18 09:50:27 server dovecot: imap(user): expunge: box=INBOX.Euro Brand, uid=2109, msgid=<GV1P195MB16414FAC3D4BAC6326F956048351A(a)GV1P195MB1641.EURP195.PROD.OUTLOOK.COM>, size=7597628, vsize=7698214, from="Masked User" <masked.user(a)somedomain.com>, subject=testing Jul 18 09:50:28 server dovecot: imap(user): delete: box=INBOX.Euro Brand, uid=2110, msgid=<GV1P195MB16414FAC3D4BAC6326F956048351A(a)GV1P195MB1641.EURP195.PROD.OUTLOOK.COM>, size=7597654, vsize=7698247, from="Masked User" <masked.user(a)somedomain.com>, subject=testing Jul 18 09:50:28 server dovecot: imap(user): expunge: box=INBOX.Euro Brand, uid=2110, msgid=<GV1P195MB16414FAC3D4BAC6326F956048351A(a)GV1P195MB1641.EURP195.PROD.OUTLOOK.COM>, size=7597654, vsize=7698247, from="Masked User" <masked.user(a)somedomain.com>, subject=testing ...

Message Duplication
by Doug Hardie 17 Jul '25

17 Jul '25

I have a persistent, but infrequent situation where a message from a mail list will appear in the list of messages twice. The IDs are identical between the copies. There is only one copy of the email in the mailbox. It appears that there are two entries in some index. Apple's mail gets confused by this. If I delete the first entry, the second remains but is tagged as found in mailbox NULL. It cannot easily be deleted. My first thought was that sieve was saving two copies. So I pulled a copy of the original email and ran sieve-test on it. It is only saved once to the proper mailbox. I have not been able to determine if the problem is in Dovecot or Apple's mail app. From what I see, it could be either. I would appreciate any ideas on how to diagnose this further. Thanks, -- Doug

Any planned 2.4.2 release date
by Andreas Haerter 14 Jul '25

14 Jul '25

Hi, I am currently planning the migration from Dovecot 2.3 to 2.4 and was wondering if version 2.4.2 is just around the corner (and it therefore might make sense to wait a few more days). Is there any planned schedule or does it still make sense to migrate to 2.4.1 within the next ~14 days? -- Regards, Andreas Haerter foundata GmbH Steinhäuserstr. 20 76135 Karlsruhe Sitz der Gesellschaft: Karlsruhe Registergericht: Amtsgericht Mannheim, HRB 714807 Geschäftsführung: Andreas Haerter USt-IdNr.: DE284122682

Better 2.4.x docs?
by Steve Litt 13 Jul '25

13 Jul '25

Are you planning to improve your Dovecot 2.4.x documentation? The current 2.4.x documentation has: * Non-obvious links between 2.4.x and 2.3.x * Some 2.3.x specific grammar * Almost no examples * 2.4.x material is scattered across many pages * Contains a few inaccuracies * Contains some contradictions 2.4.x is such a huge change that it should have its own, standalone documentation tree exclusively for 2.4.x. This tree should have a different color scheme than your other docs so people know at a glance exactly what they're looking at. You could have a page devoted to often used dovecot.conf content, with numerous examples, documented as if there had never been an earlier version. You could have a page devoted to conversion of 2.3.x dovecot.conf to 2.4.x, once again, with numerous examples. Another page with more exotic dovecot.conf content, with numerous examples. Another page discussing the 2.3.x features that don't appear in 2.4.x, what capabilities that takes away, and how best to cobble together those capabilities for those who don't want Dovecot Professional. Another page for brand new capabilities of 2.4.x. Thanks, SteveT Steve Litt http://444domains.com

Debian 13 Trixie, Exim4, Dovecot 2.4.0. pop3, lmtp On a 2.3 system I could use: passdb { driver=passwd-file args = /etc/dovecot/passwd } userdb { driver=static args = uid=vmail gid=vmail home=/home/vmail/%u } service lmtp { unix_listener lmtp { } } passwd looks like this: test@onedomain.tlda:{BLF-CRYPT}$2y$05$[encoded] test@domain.tld:{ARGON2ID}$argon2id$v=19$m=65536,t=3,p=1$[encoded] test@two-domain.tldb:{ARGON2ID}$argon2id$v=19$m=65536,t=3,p=1$[encoded] I want to keep the passwd file as is, no extra fields. mail_uid = vmail mail_gid = vmail mail_home = /var/vmail/%{user} mail_driver = maildir mail_path = /home/vmail/%{user}/Maildir pop3_uidl_format = %{guid} passdb passwd-file { driver=passwd-file } userdb static { driver=static } Directory /var/vmail/test(a)domain.tld exists (empty). This doesn't work. Error messages: Exim log - attempt to deliver message: ** test(a)domain.tld R=dovecot_myrouter_lmtp T=dovecot_transport_lmtp: LMTP error after RCPT TO:<test(a)domain.tld>: 550 5.1.1 <test(a)domain.tld> User doesn't exist: test(a)domain.tld Dovecot debug log: master: Info: Dovecot v2.4.1-4 (7d8c0e5759) starting up for pop3, lmtp (core dumps disabled) auth(info): Info: passwd-file: unknown user - trying the next passdb lmtp(16933): Debug: Effective uid=0, gid=0, home=/run/dovecot/empty lmtp(16933): Debug: none: root=/home/vmail/raw-mail-user/Maildir, index=, indexpvt=, control=, inbox=, alt= lmtp(test(a)domain.tld)<16933><[some_string]>: Debug: auth-master: userdb lookup(test(a)domain.tld): Started userdb lookup lmtp(test(a)domain.tld)<16933><[some_string]>: Debug: auth-master: conn unix:/run/dovecot/auth-userdb: Connecting lmtp(test(a)domain.tld)<16933><[some_string]>: Debug: auth-master: conn unix:/run/dovecot/auth-userdb (pid=16922,uid=0): Client connected (fd=16) lmtp(test(a)domain.tld)<16933><[some_string]>: Debug: auth-master: conn unix:/run/dovecot/auth-userdb (pid=16922,uid=0): auth input: lmtp(test(a)domain.tld)<16933><[some_string]>: Debug: auth-master: userdb lookup(test(a)domain.tld): auth USER input: lmtp(test(a)domain.tld)<16933><[some_string]>: Debug: auth-master: userdb lookup(test(a)domain.tld): Userdb lookup failed lmtp(16933): Debug: User session is finished # doveadm user test(a)domain.tld field value uid vmail gid vmail home /home/vmail/test(a)domain.tld mail_path /home/vmail/test(a)domain.tld/Maildir How can this be fixed?

Access issue with public/shared mailboxes after migrating to v2.4.x
by Juergen Edner 08 Jul '25

08 Jul '25

Hi all, I'm currently trying to get my public/shared mailbox access working again after migration to 2.4.1. I thought I would have done all required changes, but Dovecot 2.4.1 seems to act slightly different than 2.3.x. I've tried to understand what is wrong, read the documentation multiple times and searched the internet for a solution, but unfortunately without final success. I hope you can shed some light on how to get the original behavior back. Let me explain my original setup, which worked for years without any issues. I've setup the following shared folders as an adminstrator and set the access right on a directly level, e.g. /home/imapshared imapshared:users 0770 /home/imapshared/.Parents imapshared:parents 0770 /home/imapshared/.Kids imapshared:kids 0770 This was my working Dovecot 2.3 configuration: namespace { type = shared separator = / prefix = '#Shared/' location = maildir:/home/imapshared:INDEXPVT=~/.imapmail/shared subscriptions = no } User, who were allowed to access the folder, got e.g. the 'parents' or 'kids' group assigned as secondary group, the primary one is 'users'. Based on the documentation I've modified the Dovecot 2.4 configuration as follows: namespace shared { type = shared mail_driver = maildir separator = / prefix = '#Shared/' mail_path = /home/imapshared mail_index_private_path = ~/.imapmail/shared subscriptions = no } This is what I already found out or tried to adjust: - I found out that the shared folder can be accessed if the shared folder system group is set to 'users' (primary group), but by default not if a system group is used which is the secondary group of a user (e.g. parents or kids) - In the documentation I found a hint, that Dovecot by default would now only accept the primary group. By setting the following parameter additional groups should also be accepted: mail_access_groups = yes Unfortunately, that doesn't restore the orinal functionality. - In the documentation I found a hint, that all folders which have been created by an administrator, should now be of type 'public' but changing that setting doesn't work either. "It's important that the namespace type is "public" regardless of whether you set the namespace prefix to "shared." or something else." This is the error which is logged, which is not true: Error: maildir: stat(/home/imapshared/.Parents/tmp) failed: Permission denied (euid=2000(father) egid=100(users) missing +x perm: /home/imapshared/.Parents, we're not in group 203(parents), dir owned by 2226:203 mode=0770) This is the user used to access the folder: uid=2000(father) gid=100(users) groups=100(users), ..., 203(parents), ... Do you have any idea or hint how to solve this issue and provide an example what needs to be modified in my configuration to get the original functionality back?

Pigeonhole releases
by Aleksandr Mezin 07 Jul '25

07 Jul '25

Hi. I've been using https://pigeonhole.dovecot.org/releases/2.4/ to monitor when new releases are published. Now that URL suddenly returns 403. Was it an intentional change? Why? Also, https://pigeonhole.dovecot.org/download.html still points to v2.4.0 https://pigeonhole.dovecot.org/releases/2.4/dovecot-pigeonhole-2.4.0.tar.gz as the latest release. Even though a newer v2.4.1-4 https://pigeonhole.dovecot.org/releases/2.4/dovecot-pigeonhole-2.4.1-4.tar.… was published more than 2 months ago. Also, is it v2.4.1-4 or v2.4.1? The Git tag is `2.4.1` https://github.com/dovecot/pigeonhole/releases/tag/2.4.1 but the attached tarball name ends with `-2.4.1-4` (as well as the name of the tarball on https://pigeonhole.dovecot.org/releases/) What does the `-4` suffix mean? Will it be present in future versions?

pigeonhole permission errors regarding bin_path

Hi, While trying to use the `sieve_script_bin_path` option to have Pigeonhole auto-create directories for compiled sieve scripts, I ran into some permission issues: "Error: sieve: binary /run/dovecot2/sieve/jasper/84lkfddk8d88ib7zh3zh6hmy5lrvn54x-after.svbin: save: failed to create temporary file: open(/run/dovecot2/sieve/jasper/84lkfddk8d88ib7zh3zh6hmy5lrvn54x-after.svbin.) failed: Permission denied (euid=986(dovemail) egid=985(dovemail) missing +w perm: /run/dovecot2/sieve/jasper, dir owner missing perms)" I'm using `bin_path` like this: `sieve_script_bin_path = "/run/dovecot2/sieve/%{user|username|lower}";` and the permissions of the `sieve` directory are as follows: ``` $ ls -lah sieve total 0 drwxr-xrwx 3 root root 60 Jul 5 13:01 . drwxr-xr-x 10 root root 780 Jul 5 13:00 .. dr-xr-xr-x 2 dovemail dovemail 40 Jul 5 13:01 jasper ``` `strace`ing Dovecot shows that it uses `0555` when creating this directory (but not before setting `umask` to `000`?): ``` 260940 newfstatat(AT_FDCWD</var/vmail/jappie.dev/jasper>, "/run/dovecot2/sieve/jasper", 0x7fff4306af00, 0) = -1 ENOENT (No such file or directory) 260940 umask(000) = 077 260940 mkdir("/run/dovecot2/sieve/jasper", 0555) = 0 260940 umask(077) = 000 ``` I also tried patching Pigeonhole's source to log the value of `mode`: ``` diff --git a/src/lib-sieve/sieve-storage.c b/src/lib-sieve/sieve-storage.c index e68fe39f..4c7a081f 100644 --- a/src/lib-sieve/sieve-storage.c +++ b/src/lib-sieve/sieve-storage.c @@ -887,6 +887,6 @@ int sieve_storage_setup_bin_path(struct sieve_storage *storage, mode_t mode) if (mkdir_parents(bin_path, mode) == 0) { e_debug(storage->event, - "Created directory for binaries: %s", bin_path); + "Created directory for binaries: %s %u", bin_path, mode); return 1; } ``` and this logged `365`, which - if I understand `mode_t` correctly - corresponds to `-wxrw-r-x`: ``` Debug: sieve: storage after: file: Created directory for binaries: /run/dovecot2/sieve/jasper 365 ``` Needless to say, I'm a little confused as to what's going on here - am I missing something or does this look like a Pigeonhole / Dovecot bug?

`sieve_script_bin_path` option to have Pigeonhole auto- create directories for compiled sieve scripts, I ran into some permission issues: "Error: sieve: binary /run/dovecot2/sieve/jasper/ 84lkfddk8d88ib7zh3zh6hmy5lrvn54x-after.svbin: save: failed to create temporary file: open(/run/dovecot2/sieve/jasper/84lkfddk8d88ib7zh3zh6hmy5lrvn54x- after.svbin.) failed: Permission denied (euid=986(dovemail) egid=985(dovemail) missing +w perm: /run/dovecot2/sieve/jasper, dir owner missing perms)" I'm using `bin_path` like this: `sieve_script_bin_path = "/run/dovecot2/sieve/% {user|username|lower}";` and the permissions of the `sieve` directory are as follows: ``` $ ls -lah sieve total 0 drwxr-xrwx 3 root root 60 Jul 5 13:01 . drwxr-xr-x 10 root root 780 Jul 5 13:00 .. dr-xr-xr-x 2 dovemail dovemail 40 Jul 5 13:01 jasper ``` `strace`ing Dovecot shows that it uses `0555` when creating this directory (but not before setting `umask` to `000`?): ``` 260940 newfstatat(AT_FDCWD</var/vmail/jappie.dev/jasper>, "/run/dovecot2/sieve/ jasper", 0x7fff4306af00, 0) = -1 ENOENT (No such file or directory) 260940 umask(000) = 077 260940 mkdir("/run/dovecot2/sieve/jasper", 0555) = 0 260940 umask(077) = 000 ``` I also tried patching Pigeonhole's source to log the value of `mode`: ``` diff --git a/src/lib-sieve/sieve-storage.c b/src/lib-sieve/sieve-storage.c index e68fe39f..4c7a081f 100644 --- a/src/lib-sieve/sieve-storage.c +++ b/src/lib-sieve/sieve-storage.c @@ -887,6 +887,6 @@ int sieve_storage_setup_bin_path(struct

bin_path, mode); return 1; } ``` and this logged `365`, which - if I understand `mode_t` correctly - corresponds to `-wxrw-r-x`: ``` Debug: sieve: storage after: file: Created directory for binaries: /run/ dovecot2/sieve/jasper 365 ``` Needless to say, I'm a little confused as to what's going on here - am I missing something or does this look like a Pigeonhole / Dovecot bug?

how to disable services on the docker image?
by Felix Rubio 06 Jul '25

06 Jul '25

Hi everybody! I am trying to find the cleanest way to disable services (like pop3-login, pop3, etc.) in the docker image, if possible extending the existing configuration with conf.d files. Is this possible? I have tried using the protocol keyword on those services, after setting the protocols to that ones I want, and the services still get instantiated (thus consuming resources as well). Thank you! Felix

sievec fails when run as non-root - bug?
by Genes Lists 30 Jun '25

30 Jun '25

1) With 2.4.1, when a non-root user runs sievec on their own sieve scripts it fails to run due to permission denied on the dovecot certificate key (which is only readable by root). Specifically: sievec active.sieve doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/10- ssl.conf line 10: cert_file: open(/etc/.../fullchain.pem) failed: Permission denied What is recommended way to deal with this? 2) Separate question: Might this explain why users sieve scripts are not running? I assume not as there are no 'sieve' items reported by lmtp in the logs. Config has: protocol lmtp { postmaster_address = postmaster@<domain>.com mail_plugins { sieve = yes } hostname = imap.<domain>.com } sieve_script before { driver = file path = /etc/dovecot/sieve/global active_path = remove_dup.sieve } sieve_script personal { driver = file path = ~/sieve active_path = ~/.dovecot.sieve } sieve_script after { driver = file path = /etc/dovecot/sieve active_path = default.sieve } thanks. -- Gene

Identifying spamd problems

Hi, I have use Dovecot, Spamassassin and Roundcube. My spam assassin is configured to use SQL.

SASL authentication against LDAP w/ client certs, supposed to work?
by Bruno Hertz 26 Jun '25

26 Jun '25

Hi all I'm currently testing Dovecot 2.4, considering a migration from 2.3, and all works fine except authentication against LDAP (openldap slapd) with client certificates. Which I had no problem with on 2.3 for seven years or so. Versions: Linux Alpine 3.22 Dovecot 2.4.1-4 (7d8c0e5759) Alpine package, but patched with https://github.com/dovecot/core/commit/431e328b3b035ddb187526cd13bccf29833a… Now, first a Dovecot configuration that does work, unencrypted simple bind against Unix domain socket: ldap_version = 3 ldap_uris = ldapi:/// ldap_base = ou=users,dc=mydomain,dc=internal ldap_auth_dn = cn=dovecot,dc=mydomain,dc=internal ldap_auth_dn_password = secret passdb ldap { bind = no default_password_scheme = SSHA ldap_filter = (&(objectClass=posixAccount)(uid=%{user})) fields { user = %{ldap:uid} password = %{ldap:userPassword} } } Meaning I'm doing password lookups, IMAP users can authenticate against Dovecot, Postfix correctly delivers incoming emails, everything works flawlessly. Now the setup I'm talking about, which does not work: ldap_version = 3 ldap_uris = ldaps://localhost.mydomain.internal ldap_base = ou=users,dc=mydomain,dc=internal ldap_auth_sasl_mechanisms = external ssl_client_cert_file = /etc/ssl/ldap/dovecot.crt ssl_client_key_file = /etc/ssl/ldap/dovecot.key # this just as a precaution during testing, validation *does* work ssl_client_require_valid_cert = no ssl_client_ca_dir = /etc/ssl/certs passdb ldap { bind = no default_password_scheme = SSHA ldap_filter = (&(objectClass=posixAccount)(uid=%{user})) fields { user = %{ldap:uid} password = %{ldap:userPassword} } } What happens here, as far as I can see, is Dovecot connects to slapd, initiates a SASL session but then fails to send the client certificate. slapd realizes the cert isn't coming, asserts there's no other SASL "external" method to fall back to and disconnects Dovecot. Game over. Now, before somebody thinks 'maybe something wrong with the certs or so', the very same setup on the very same machine works perfectly with two other client types, namely - openldap standard utils - postfix (recipient lookup) With the utils I have this setup, with the same client cert URI ldaps://localhost.mydomain.internal BASE ou=users,dc=mydomain,dc=internal SASL_MECH external TLS_REQCERT demand TLS_CACERT /root/ssl/ca.crt TLS_CERT /etc/ssl/ldap/dovecot.crt TLS_KEY /etc/ssl/ldap/dovecot.key and ldapwhoami connects without problem, and with ldapsearch I can perform the very same searches Dovecot is supposed to do. Postfix, for recipient lookups, I have configured like this: version = 3 server_host = ldaps://localhost.mydomain.internal search_base = ou=users,dc=mydomain,dc=internal query_filter = (&(mail=%s)) result_attribute = uid bind = sasl sasl_mechs = external tls_require_cert = demand tls_ca_cert_dir = /etc/ssl/certs tls_cert = /etc/ssl/ldap/dovecot.crt tls_key = /etc/ssl/ldap/dovecot.key Again, no problem to authenticate agains LDAP with the very same client certificate. The CA is correctly installed into /etc/ssl/certs , by the way, with update-ca-certificates. So out of 3 client types with the very same setup only Dovecot fails to successfully negotiate the client cert SASL session, while, after a good look through the docs, I really don't see any other settings I could tweak. Thoughts? Greetings, Bruno

Dovecot quota and IMAP MOVE
by marekstefanka＠duck.com 26 Jun '25

26 Jun '25

Hello, I would like to kindly ask, if there is some recommendation for dovecot quota configuration, to prevent quota-warning triggering when IMAP MOVE command is executed close to some thresholds. Problem seems to be this: Jun 10 11:08:20 srv1 dovecot[39677]: imap(box1(a)domain.com)<48726><0aCoCTQ3TC8KHgcC>: Debug: quota: Executing warning: quota-warning box1(a)domain.com (because bytes=3713971 -> 7301217 over limit 4096000) Jun 10 11:08:20 srv1 dovecot[39677]: imap(box1(a)domain.com)<48726><0aCoCTQ3TC8KHgcC>: Debug: quota: Executing warning: quota-warning box1(a)domain.com (because bytes=7301217 -> 3713971 below limit 4096000) So during any IMAP MOVE, which is copy-then-delete process, quota goes over and then below limit, triggering closest threshold. Quota config: quota = count:User quota quota_vsizes = yes # default, we specific user limits via sql quota_rule = *:storage=0 quota_grace = 50M quota_warning = storage=100%% quota-warning %u quota_warning2 = -storage=100%% quota-warning %u quota_warning3 = storage=90%% quota-warning %u quota_warning4 = storage=80%% quota-warning %u Recommended fix does not seems to work (tried multiple namespaces): quota_rule = Folder:storage=+100M Dovecot version is 2.3.21.1 Thank you for any help with this.

Re: Problem email client iPhone ios18.2

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. Kind Regards Brent Clark Good day everyone, I’m trying to authenticate against a constant database (CDB) file.

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

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
