And when using fchown($FileDescriptor, 2000, 2000) there is no error. I can't find a way to tell dovecot to use uid & gid 2000 when he tries to do fchown. If I create a directory structure manually, everything works well. Maybe we can make some parameter in config, telling that we are using virtiofs and skip EINVAL when doing fchown...

Auth timeout after reload
by rudolf＠padaru.de 29 Nov '24

29 Nov '24

Hello everyone, I have a Dovecot running and can often observe that the auth process goes wrong if a reload occurs at the moment of authentication. I have installed dovecot 2.3.21.1 on ubuntu 20. Whether the error also occurs under other versions, I cannot say at the moment. I have included three examples from the mail log: ## start logs ## # 1 # Nov 27 11:28:18 <myServer> dovecot[946292]: auth: Debug: sql(<myUser>,<myIP>,<I1eibOInIOW5zIKi>): Finished passdb lookup Nov 27 11:28:18 <myServer> dovecot[946292]: auth: Debug: auth(<myUser>,<myIP>,<I1eibOInIOW5zIKi>): Auth request finished Nov 27 11:30:49 <myServer> dovecot[946292]: auth: Error: plain(<myUser>,<myIP>,<I1eibOInIOW5zIKi>): Request 946296.13397 timed out after 151 secs, state=3 Nov 27 11:28:18 <myServer> systemd[1]: Reloading Dovecot IMAP/POP3 email server. # 2 # Nov 27 09:05:08 <myServer> dovecot[2940195]: auth: Debug: auth(<myUser><myIP>,<nK2cbOAnaMGiIdFS>): Auth request finished Nov 27 09:07:38 <myServer> dovecot[2940195]: auth: Error: plain(<myUser>,<myIP>,<nK2cbOAnaMGiIdFS>): Request 2940206.363 timed out after 150 secs, state=3 Nov 27 09:05:07 <myServer> systemd[1]: Reloading Dovecot IMAP/POP3 email server. # 3 # Nov 27 10:02:18 <myServer> dovecot[3736041]: auth: Debug: auth(<myUser><myIP>,<1v4HOeEnWtG5zIKi>): Auth request finished Nov 27 10:04:48 <myServer> dovecot[3736041]: auth: Error: plain(<myUser>,<myIP>,<1v4HOeEnWtG5zIKi>): Request 3736048.4962 timed out after 150 secs, state=3 Nov 27 10:02:18 <myServer> systemd[1]: Reloading Dovecot IMAP/POP3 email server. ## end logs ## You can clearly see that the sql query works, but then the auth-worker seems to hang. I suspect that the auth-worker sends the request to the DB, receives the response and is then killed before it can log in the user via imap. This then leads to some users not being able to log in for a long time. I write many configs on the server automatically, then I always run a reload so that the changed config is accepted. Is this a bug or do I have to change something in my setup?

"INBOX can't be deleted" error when syncing from imapc
by Andy Balholm 28 Nov '24

28 Nov '24

I'm syncing mail from an IMAP server to local Maildirs with `doveadm backup -R`, and I sometimes get an error the second time I sync an account: > Mailbox INBOX sync: mailbox_delete failed: INBOX can't be deleted. I've figured out that the sync completes the first time without an error, but the UIDVALIDITY of the INBOX Maildir doesn't match the UIDVALIDITY on the IMAP server. Then the second time doveadm detects the mismatch and wants to delete the INBOX, but it can't because Maildir INBOXes can't be deleted. So I think the root cause is that the INBOX is being created with the wrong UIDVALIDITY in the first place. It only seems to happen when there are no messages in the INBOX on the server at the time the Maildir is created, but it doesn't seem to happen all the time. Is there anything I can do to make the sync job run smoothly? Andy

Director to keep redirecting users to the same server even it is down

bug? dsync extremely much slower on forward than reverse direction
by Bjørnar Ness 27 Nov '24

27 Nov '24

I have been experimenting with dsync lately, and to my surprise I found that dsync in forward direction is extremely slow compared for reverse (-R) direction for the exact same data, disk caches flushed both times. I have created a docker-compose setup to prove my findings. Am I missing something here, or is this a bug? link to tests: https://github.com/bjne/dovecot-dsync-benchmark -- Bj(/)rnar

How to get the X-Original-To: header added for LMTP? I tried adding: lda_original_recipient_header = X-Original-To But that didn't add the header for mail over LMTP. I couldn't find anything else in the docs.

Extended LIST not working
by tim＠linux-daus.de 25 Nov '24

25 Nov '24

Hi, i try to use extended LIST command but it doesn't work out. I wonder if there is any option necessary to enable it or some option that prevent using extended LIST commands (for example Courier compatible namespace config). I didn't find anything in the documentation. Did anyone notice a similar behavior? curl -u $IMAPUSER:$IMAPPW imaps://... -X 'STATUS INBOX (MESSAGES UNSEEN)' * STATUS INBOX (MESSAGES 105 UNSEEN 79) curl -u $IMAPUSER:$IMAPPW imaps://... -X 'LIST "" "INBOX" RETURN (STATUS (MESSAGES UNSEEN))' * LIST () "." INBOX Best regards, Tim

Authentication hangs on before SSL initialization
by Matt 22 Nov '24

22 Nov '24

sharing sso between regular mail client and web applications
by Marc 20 Nov '24

20 Nov '24

I am testing a bit with sso with keycloak, I was wondering if/how it is possible that your logged in session between eg Thunderbird and dovecot can be used as a single sign on in webapplications. So as long as you have an active session with dovecot you can access all your web applications without the need to login.

Fatal: sql proxy::sqlite-proxy: Can't open configuration file
by Matt 14 Nov '24

14 Nov '24

Hi, I'm running into a problem where I'm not sure anymore if it's possible to proxy to an SQLite database file using a dict for authentication. The docs are unclear about it and I thought it was not possible as it's not a connection for SQLite but a file-read where the documentation shows different. ov 14 13:57:52 auth: Debug: Loading modules from directory: /usr/lib/dovecot/auth Nov 14 13:57:52 auth: Debug: Module loaded: /usr/lib/dovecot/auth/lib20_auth_var_expand_crypt.so Nov 14 13:57:52 master: Error: service(auth): command startup failed, throttling for 4.000 secs Nov 14 13:57:52 auth: Debug: Module loaded: /usr/lib/dovecot/auth/libdriver_sqlite.so Nov 14 13:57:52 auth: Fatal: sql proxy::sqlite-proxy: Can't open configuration file proxy::sqlite-proxy: No such file or directory doveconf -n does show me the dict being loaded, the file exists as well but it still says not found. dict { sqlite-proxy = sqlite:/etc/dovecot/conf.d/dicts/sqlite/sqlite-connection.conf.ext } What am I missing here ?

Does anyone have a current config example using openid and with roundcube. I like to add this next to 'regular' logins'. I was able to login once but know I am getting these in the logs " No requests to service for this peer (1 connections exist, 0 pending)" I have added the 2 passdb with links to dovecot-oauth2.token.conf.ext from this manual[1], but it is not really clear if I need these and can just add a config file with openid_configuration_url [1] https://doc.dovecot.org/2.3/configuration_manual/authentication/oauth2/

Hello! I'm using dovecot with keycloak for oauth authentication. My config is: client_id = dovecot client_secret = MY_SECRET introspection_url = https://MY_KEYCLOAK/realms/master/protocol/openid-connect/token/introspect introspection_mode = post pass_attrs = pass=%{oauth2:access_token} Everything worked great on version 2.3.20. After upgrading to version 2.3.21.1 oauth stopped working with errors: auth: Debug: http-client: conn [::1]:443 [1]: Got 401 response for request [Req1: POST https://MY_KEYCLOAK/realms/master/protocol/openid-connect/token/introspect] Unauthorized (took 5 ms + >Aug 16 00:23:58 auth: Error: oauth2(MY_EMAIL,127.0.0.1,<HADwdb8f+PN/AAAB>): oauth2 failed: Introspection failed: No username returned I tried all combination of configurations, debugging and versions of keycloak.

Locking box for backups
by Steve Atkins 12 Nov '24

12 Nov '24

I’m running 2.3.19.1 on a system that isn’t set up to support filesystem snapshots. So I’d like to back up my mdbox mailboxes at a filesystem level (with rsync, or something equivalent). I’m assuming that to get a consistent backup I should lock the mailbox while I copy it. How should I acquire a (write) lock on an mdbox mailbox? Cheers, Steve

replication and backup
by Philippe 12 Nov '24

12 Nov '24

Hi all & thanks Aki for adding me to the list. First of all, I'm not a dovecot user yet. For several years now I use cyrus imapd and never saw the urge to switch, until I recently lost random mails from my mailbox which were neither temporally connected nor related in some other way. Fortunately, I had a rolling replication which never expunges, so I was able to restore them. While circumventing some pitfalls during the restore, I learned that the backup and restore procedure cyrus imapd offers is deprecated and will be removed. Now I ponder whether or not I should switch the mda. Does dovecot offer the following? - setting up a rolling replication which replicates every action made to the mailbox (flags, mark as deleted, relocations, etc.) to a different server (one way only) - NOT expunging the emails that have been marked as deleted on the slave server or expunging only manually - restoring selected emails from the slave directly to the master The slave server doesn't need to be accessible via imap, I'd be happy to search for some header data (subject, recipient, sender, date, ...) and restore the email by command line using its uuid or message-id or something like that. Browsing the documentation I found "doveadm-backup" which is using "dsync", but I'm not sure whether or not it fits my requirements. I'd love to hear your opinions. Kind regards, Philippe

SMTPUTF8 in dovecot lmtp - current status

Proper configuration of fts-xapian for dovecot
by Torge Riedel 10 Nov '24

10 Nov '24

Dears, I recently installed the package dovecot-fts-xapian on my Ubuntu 22.04 VM, where dovecot 2.3.16 is installed. I enabled the plugins mail_plugins = $mail_plugins fts fts_xapian plugin { ### # fts fts = xapian fts_xapian = partial=3 full=20 fts_autoindex = yes fts_enforced = yes #fts_autoindex_exclude = \Trash # Index attachements fts_decoder = decode2text } I skip to show the "service indexer-worker" and "decode2text" for the moment. After restarting dovecot I ran doveadm index -A \* which ran without any issues. But for the moment I am faced with two issues I am unable to solve on my own and also didn't found a solution on the internet: 1. The indexer created a new directory "xapian-indexes" in the user's mail folder (where also "INBOX", "Drafts", "Sent", ... exists), with the result that you can see this folder in Thunderbird and GMail Android App. How to hide / disable the folder to mail programs, IMHO no mail program should have access to it. 2. When listing the capabilities of my mail server I get "CAPABILITY IMAP4rev1 SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SPECIAL-USE LITERAL+ AUTH=PLAIN AUTH=LOGIN" and it seems to lack the FTS capability(s). Am I right? And should dovecot set the capabality on its own or is something missing in the config? If you need more info, just let me know please. Thanks and kind regards Torge

What is the appropriate action for out of memory error for exceeding vsz_limit in my situation?
by Steve Dondley 08 Nov '24

08 Nov '24

Hi, I have sporadic messages on my server about an account getting an out of memory error: Fatal: master: service(imap): child 17910 returned error 83 (Out of memory (service imap { vsz_limit=325 MB }, you may need to increase it) - set CORE_OUTOFMEM=1 environment to get core dump) In response, I raised the limit from 256MB up to 325. That didn’t seem to help. The server has only 512 MB of RAM so I’m afraid to go much higher. I googled around a bit and some people are saying that when the dovecot.index.cache grows too large, it can cause these errors. The imap account has a dovecot.index.cache file that is 167 MB which seems to be well below the limit (but maybe it is compressed?). So I’m not entirely sure as to what the underlying problem is. So before upgrading to the server to 1024 MB of ram and going on a wild goose chase, I just want to get input on whether I have positively identified the problem and whether there might be something else I can do to manage this problem.

Expunging and deleting old messages - moving from cyrus-imap
by Nick Howitt 07 Nov '24

07 Nov '24

I have just moved from cyrus-imap to dovecot. In cyrus I had an automatic purge of messages marked as deleted with a cron job: /usr/lib/cyrus-imapd/cyr_expire -E 1 -X 7 -D 7 -E = Expire Days -X = Expunge days What is the equivalent in doveadm? doveadm expunge -A DELETED BEFORE 1w Is there any equivalent to expire messages marked as deleted? I can't remember why I have it as I set up Cyrus so long ago. I also delete from deleted (INBOX.trash) anything older than a year. In Cyrus, it is run from an event in the configuration: trashPurge cmd="ipurge -s -X -f -d 365 user/*/Trash" at=0104 I would be happy to run it from cron, so does this work: doveadm expunge -A mailbox INBOX.trash SENTBEFORE 52w Except I get: doveadm(nobody): Error: mkdir(/nonexistent/.Maildir) failed: Permission denied (euid=65534(nobody) egid=65534(nogroup)) I can run it for the individual users but not -A.

I can't > remember why I have it as I set up Cyrus so long ago. If by expire, you mean expunge, this is more or less what I used in a nightly cron script doveadm expunge -A $ mailbox 'Deleted Items' OR mailbox 'Deleted Messages*' OR mailbox Junk OR mailbox Trash OR \( mailbox INBOX Deleted $ \) BEFORE 7d In English, for all users, delete any messages in commonly named trash folders or any messages in INBOX marked as deleted that are older than a week. I recall one quirk: if the mailbox didn't have a cached entry for the message's age, the filter criteria would miss this and it would remain in the mailbox. I'm not sure if this still happens, but I got around this by seeding the cache by doing a doveadm search for that metadata (date.received?). Joseph Tam <jtam.home(a)gmail.com>

Dovecot advertises QUOTA as an CAPABILITY only after login. GPT believes this is why Tbird doesn't show the quota on the status bar, because it's looking for the quota before login and not after. Does anyone know if its possible to get dovecot to advertise QUOTA before login?

IMAP quota reporting free disk space
by piotr＠connecta.pl 06 Nov '24

06 Nov '24

Hi, Is it possible to make IMAP quota commands report free filesystem space? I don't want to set quota limits to individual users, but it would be nice to have an information on the bottom of Thunderbird window about free disk space (it could be percentage of the total disk size). Anyway I have trouble with quota reporting itself, because I tried to setup a regular quota (100G) first, but somehow Thunderbird doesn't report free quota as it does in case of Gmail accounts. I added to 20-imap.conf: protocol imap { mail_plugins = $mail_plugins quota imap_quota } and to 90-quota.conf: plugin { quota = maildir quota_rule = *:storage=100G } What else should I add to enable reporting? (without warning emails, commands changing quota and all that stuff) P.

Upgrade Dovecot Cluster 2.2 to 2.3
by Steven Varco 05 Nov '24

05 Nov '24

Hi All I’m planing to upgrade/migrate my dovecot cluster with two dovecot 2.2.36 nodes to 2.3.16. They use Maildir als IMAP backend and will continue to use that in the future. Can I just: - Install a new Server (AlmaLinux 9) - Stop dovecot on the old node-2 - Copy all the data from the old mail directory of node-2 to the new one - Install dovecot 2.3 on the new on with more or less the same config and let it run - Repeat the same with old node-1 ? Or would it be better to start of with an empty mail directory and let the other old node imapsync the data to the new one? - What would the advantage be (over the disadvantage that it may take some time to get everything synced)? I know that Maildir are just static files, so moving them to the new server should not be a problem. I’m thinking more about indexes created by dovecot 2.2.36… Are they read without issues with the newever dovecot 2.3.16 or should I consider a re-index. or something the like? thanks in advance, Steven -- https://steven.varco.ch/ https://www.tech-island.com/

IRC channel link on the website
by Sebastian Crane 04 Nov '24

04 Nov '24

Dear all, On the Dovecot website, I noticed that the IRC link isn't clickable: https://www.dovecot.org/support/ The Markdown-esque square brackets suggest to me that this should be a hyperlink, but it's just plain text at the moment. The other issue is that there is no hash symbol before the channel name, so even if it were clickable the user's IRC client would start a private message rather than join the channel. Best wishes, Sebastian

dovecot-lda from www-data - doesnt work
by Sebastian Nielsen 01 Nov '24

01 Nov '24

m trying to deliver email from a webform, but its not working. I then tried manually in the console: WORKS: sudo -u info /usr/lib/dovecot/dovecot-lda -d info DOES NOT WORK: sudo -u www-data /usr/lib/dovecot/dovecot-lda -d info sudo -u postfix /usr/lib/dovecot/dovecot-lda -d info sudo -u dovecot /usr/lib/dovecot/dovecot-lda -d info I need to be able to deliver email from "www-data" to any user on the system (that is a valid dovecot-lda mail user). It seems a security setting blocks it. I have already set authdb to 0777 in dovecot settings (because otherwise it gives an error about lookup rights), and also enabled stats-writer and stats-reader with 0666. so no more error messages in log, but the above commands that does NOT work, terminate immediately, while the working command waits for email from STDIN. No error messages in either log or on STDOUT/STDERR. What can be the problem?

Namespace configuration
by Scott Q. 31 Oct '24

31 Oct '24

We are having an issue with our namespace configuration, as per the eM Client folks. We present the following namespaces via IMAP, with Dovecot as backend. This is the actual imap conversation 08:37:10.896|03E| 01: A4 ID ("name" "eM Client" "version" "10.1.4393.0" "GUID" "EMCLIENT_V1" "vendor" "eM Client" "contact" "support(a)emclient.com") 08:37:10.961|03E| 01: * ID ("name" "Dovecot") 08:37:10.961|03E| 01: A4 OK ID completed (0.001 + 0.000 secs). 08:37:10.961|03E| 01: A5 NAMESPACE 08:37:11.184|03E| 01: * NAMESPACE (("" ".")("Labels." ".")) (("shared." ".")) NIL 08:37:11.184|03E| 01: A5 OK Namespace completed (0.001 + 0.162 + 0.161 secs). As per them, the problem is the first empty prefix: "The problem is not necessarily in the fact that it is empty but because it is then mixed with another one with a prefix. Logically it means that everything in the empty namespace must be mixed together with the prefixed namespace and that is not really ok." "NAMESPACE (("personal." ".")("Labels." ".")) (("shared." ".")) NIL would make sense as both personal namespaces point to different directory structures." Reading the RFC I'm not understanding this at all, but then again, maybe I'm wrong. Anyone care to shed some light on how multiple namespaces should be defined ? Thank you, Scott

Inboxes incorrectly become /var/mail/%u
by ma.sao＠msa.hinet.net 29 Oct '24

29 Oct '24

With configuration "mail_location = maildir:~/Maildir", incoming mails are always saved to /var/mail/%u , which are invisible to Thunderbird. How do I configure Dovecot to save incoming mails to ~/Maildir/cur/ and ~/Maildir/new/ ? Thank you in advance! context: I replaced my host recently. Version 2.3.13 running in the old host used to correctly save incoming mails to ~/Maildir. I copied the files in /home/user1/Maildir/ Dovecot 2.3.13 managed to my new host where the new Dovecot 2.3.19.1 runs. Thunderbird now correctly displays files in /home/user1/Maildir/cur/ in the new server as inbox mails, but obviously it can not see file /var/mail/user1 in the new server. ===== Output of "dovecot -n" follows. # 2.3.19.1 (9b53102964): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.19 (4eae2f79) # OS: Linux 6.1.0-22-amd64 x86_64 Debian 12.7 # Hostname: example auth_mechanisms = plain login disable_plaintext_auth = no mail_location = maildir:~/Maildir mail_privileged_group = mail namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } protocols = " imap" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } service imap-login { inet_listener imap { port = 143 } } ssl = required ssl_cert = </etc/letsencrypt/live/example.com/fullchain.pem ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it userdb { driver = passwd } ======== Output of "ls -la /home/user1/Maildir/" in my new host follows. total 112 drwx------ 9 user1 user1 4096 Oct 26 23:39 . drwxr-xr-x 4 user1 user1 4096 Oct 26 23:39 .. drwx------ 5 user1 user1 4096 Oct 26 22:18 .Drafts drwx------ 5 user1 user1 4096 Oct 29 00:11 .Sent drwx------ 5 user1 user1 4096 Oct 26 23:39 .Templates drwx------ 5 user1 user1 4096 Oct 29 00:12 .Trash drwx------ 2 user1 user1 4096 Oct 26 21:14 cur -rw------- 1 user1 user1 609 Oct 26 20:15 dovecot-uidlist -rw------- 1 user1 user1 8 Nov 13 2023 dovecot-uidvalidity -r--r--r-- 1 user1 user1 0 Oct 15 2022 dovecot-uidvalidity.634a88ee -rw------- 1 user1 user1 600 Oct 18 16:39 dovecot.index -rw------- 1 user1 user1 13296 Oct 26 21:23 dovecot.index.cache -rw------- 1 user1 user1 26084 Oct 26 21:14 dovecot.index.log -rw------- 1 user1 user1 744 Oct 22 18:32 dovecot.list.index -rw------- 1 user1 user1 7232 Oct 29 00:12 dovecot.list.index.log -rw------- 1 user1 user1 96 Nov 13 2023 dovecot.mailbox.log drwx------ 2 user1 user1 4096 Oct 26 20:15 new -rw------- 1 user1 user1 33 Nov 13 2023 subscriptions drwx------ 2 user1 user1 4096 Oct 25 21:32 tmp ==== Output of "ls -l /var/mail" follows. total 288 -rw------- 1 user1 mail 35086 Oct 29 18:02 user1 -rw------- 1 daemon mail 36244 Oct 28 12:32 daemon -rw------- 1 debian mail 36223 Oct 26 21:32 debian -rw------- 1 dovecot mail 36248 Oct 28 19:18 dovecot -rw------- 1 games mail 36223 Oct 27 12:38 games -rw------- 1 news mail 36237 Oct 27 13:52 news -rw------- 1 nobody mail 36266 Oct 27 15:31 nobody -rw------- 1 sshd mail 36195 Oct 29 12:36 sshd

Aggregating auth/proxy events
by matus.vlcek＠gmail.com 28 Oct '24

28 Oct '24

Hi, I'm working on aggregating event logs and trying to correlate all related events using session IDs. However, I’m struggling with some events as they're missing the session ID. 1. proxy_session_* events lack a session ID field, making it difficult to pair them with auth_request_* events. 2. when using dovecot as sasl for postfix with a unix listener, both auth_request_* and auth_passdb_request_* events are missing the session ID too. Example of the fields object for auth_request_finished when using smtp. It's missing multiple common fields, but session ID is, imho, the most important one. https://doc.dovecot.org/2.3/admin_manual/list_of_events/#id1 ``` categories: [ "auth", "service:auth" ] "fields": { "translated_user": "alex", "mechanism": "LOGIN", "real_remote_ip": "X.X.X.X", "user": "alex", "transport": "insecure", "local_ip": "X.X.X.X", "remote_ip": "X.X.X.X", "real_local_ip": "X.X.X.X", "policy_result": "ok", "service": "smtp", "duration": 96764, "original_user": "alex" }, ``` Would it be possible to add session ID fields to these logs? Alternatively, is there another method to correlate all the session related logs? Thanks, Matus Dovecot v. 2.3.21

LMTP rejecting aliased emails
by Nick Howitt 27 Oct '24

27 Oct '24

Hi, I am pretty new to Dovecot and totally new to LMTP. I have normal delivery working but I am struggling with aliases. In my mail queue I am seeing things like: -Queue ID- --Size-- ----Arrival Time---- -Sender/Recipient------- E0F617055DB 720 Sat Oct 26 14:50:24 clamav(a)mydomain.com (host mail.mydomain.com[private/dovecot-lmtp] said: 451 4.3.0 <clamav(a)mydomain.com> Temporary internal error (in reply to end of DATA command)) clamav(a)mydomain.com But in my /etc/aliases, I am aliasing clamav to nick and nick(a)mydomain.com is a valid mail box that can receive normal mail. The corresponding line in the mail log is: 2024-10-26T14:55:56.385500+01:00 mail-www dovecot: lmtp(1371485): Error: lmtp-server: conn unix:pid=1371484,uid=102 [1]: rcpt clamav(a)mydomain.com: Failed to initialize user: Mail access for users with UID 107 not permitted (see first_valid_uid in config file, uid from userdb lookup). How do I get round this issue? I can drop the minimum UID to 0, but then all system users are deemed valid for mail which is not true. None of them are. Thanks, Nick

sieve crashes when two optional include scripts are missing
by Michal Hlavinka 26 Oct '24

26 Oct '24

Hi, we've found an issue with sieve plugin. When script includes two missing optional scripts, it causes crash. For reproducing the issue, script names must belong to same hash table node, so either two scripts with same name or scripts where 'hash(name) % table->size' results in same value, like missing_a and missing_aa in reproducer below. Reduced reproducer: cat >dovecot.min.conf <<EOF mail_location = maildir:~/Maildir plugin { sieve = file:/tmp;active=/tmp/dovecot.sieve } EOF cat >reproducer.sieve <<EOF require "include"; include :personal :optional "missing_a"; include :personal :optional "missing_aa"; EOF echo -n > empty sieve-test -c dovecot.min.conf reproducer.sieve empty any test mail would do, but empty file is enough for reproducer # return sblock->id causes the crash as sblock is NULL backtrace: (gdb) bt #0 sieve_binary_block_get_id (sblock=0x0) at src/lib-sieve/sieve-binary.c:421 #1 ext_include_execute_include (renv=0x5555555bbed8, include_id=1, flags=EXT_INCLUDE_FLAG_OPTIONAL) at plugins/include/ext-include-common.c:696 #2 opc_include_execute (renv=0x5555555bbed8, address=0x5555555bbf10) at plugins/include/cmd-include.c:399 #3 sieve_interpreter_operation_execute (interp=0x5555555bbe88) at src/lib-sieve/sieve-interpreter.c:901 #4 sieve_interpreter_continue (interp=0x5555555bbe88, interrupted=0x0) at src/lib-sieve/sieve-interpreter.c:959 #5 sieve_interpreter_start (interp=0x5555555bbe88, result=0x5555555b9230, interrupted=0x0) at src/lib-sieve/sieve-interpreter.c:1049 #6 sieve_interpreter_run (interp=0x5555555bbe88, result=0x5555555b9230) at src/lib-sieve/sieve-interpreter.c:1057 #7 sieve_run (sbin=0x55555558ee18, result=0x5555555b9230, eenv=0x7fffffffe890, ehandler=0x55555558c338) at src/lib-sieve/sieve.c:357 #8 sieve_test (sbin=0x55555558ee18, msgdata=0x7fffffffe9f0, senv=0x7fffffffea30, ehandler=0x55555558c338, stream=0x5555555b2cd0, flags=SIEVE_EXECUTE_FLAG_LOG_RESULT) at src/lib-sieve/sieve.c:598 #9 main (argc=5, argv=0x555555567a10) at src/sieve-tools/sieve-test.c:391 issue seems to be caused by lib-sieve/plugins/include/ext-include-common.c: ext_include_generate_include on first pass (script) the check for script already compiled into binary at 529: included = ext_include_binary_script_get_include_info(binctx, script); returns NULL, so code goes through 'else' block where it hits sieve_script_is_open(script) check. It includes script with NULL block, returns 0 so caller cmd_include_generate does not emit anything. On second pass the above 'included' check returns first missing script, it goes through true block where it just checks flags and returns non-zero, so caller this time goes through the emit code block and the previously included NULL sblock gets referenced causing crash later. Note: despite scripts have different name, they pass the "same script" check because sieve_file_script_equals compares 0==0 dev & inode numbers as scripts do not exist. This is why scripts do not have to have same names. Side effect of this is that as missing_a and missing_aa are treated like the same script, only first one is linked in compiled svbin. Which means that if missing_aa reappears later, svbin won't get recompiled. Another manifestation of the issue is when included missing_a script is present when main script is compiled and later missina_a is removed again. During execution, script is not recompiled and it aborts for hash table dupe check: sieve_binary_open->ext_include_binary_script_include->hash_table_insert There are several ways how to solve this. I've tried a few, but there were other corner cases that appeared. One tried way was for example ext_include_generate_include in the 'if (included)' replicate the check sieve_script_is_open(...) from else block, just check flags, no include and set result to 0. Another way to solve this is to return from ext_include_execute_include early if sblock is NULL just before it tries to derefernce it, similarly as it does if it fails 'once' check. Same for dumping in opc_include_dump. Whilst the first approach seems a bit better, it won't stop crashing in existing environments as it won't trigger svbin recompilation and svbin would fail. This means that the second soultion is sort of needed anyway. This still won't solve the problem with different missing scripts as only first one would be able to trigger recompilation when file becomes available. Just including both in the mentioned function won't work either as they would still be evaluated as same and hash table anti-dupe check would trigger abort. So some changes in script comparison seem needed anyway. This is what I've used in my approach. Return early from ext_include_execute_include and opc_include_dump if sblock is NULL and change sieve_file_script_equals to compare also script->location for missing scripts (when inode is 0). Let me know if you need more information. Cheers, Michal Hlavinka

Ignore specific subfolders within Maildir?
by Ralph Seichter 25 Oct '24

25 Oct '24

Consider Dovecot with "mail_location = maildir:~/.maildir". Is it possible to configure Dovecot to completely ignore directories like ~/.maildir/.foo ? The subdirectory .foo is created by third party software and the name cannot be changed. Because of the leading dot, Dovecot interprets ~/.maildir/.foo as IMAP folder /foo by default, creates the typical subdirectory structure with cur/new/tmp, and exposes ~/.maildir/.foo to IMAP clients. Not being able to change the name or location of .foo, I would like to tell Dovecot to ignore .foo's presence altogether. So far I have not found documentation about how that can be done (or if it can). Helpful pointers are appreciated. -Ralph

"client_id" in lua script
by ecdlguy＠gmail.com 25 Oct '24

25 Oct '24

Hi, I'm trying to block specific MUAs, like e.g. Outlook-App for iOS and Android or Xiaomi Mail / MiMail using a lua script. While implementing this, I noticed that "client_id" is always nil in the lua script or I am doing something wrong. This is part of the postfix config: imap_id_retain = yes imap_id_log = * passdb { driver = lua args = file=/etc/dovecot/lua/badimapid.lua blocking=yes } Logging (imap_id_log = *) works, the dovecot log has entries like: imap(user@domain)<226><pWFZx9siRt+CUwMp>: ID sent: name=Thunderbird, version=115.15.0 Here is the content of the lua-script file: function auth_passdb_lookup(req) req.log_info('badimapid info: user="'..req.user..'", client_id="'..req.client_id..'"') return dovecot.auth.PASSDB_RESULT_NEXT, "" end function script_init() return 0 end function script_deinit() end In principle, "req.client_id" should contain the client id string according to https://doc.dovecot.org/2.3/configuration_manual/authentication/lua_based_a… However, dovecot log reads: auth-worker(163): Error: conn unix:auth-worker (pid=162,uid=401): auth-worker<27>: lua(user@domain): db-lua: lua_pcall(auth_passdb_lookup, 1, 2) failed: /etc/dovecot/lua/badimapid.lua:2: attempt to concatenate a nil value (field 'client_id') Why is client_id nil?

fixing sieve (?)
by Stefan G. Weichinger 24 Oct '24

24 Oct '24

Yesterday I was told that at a customer the vacation scripts don't work anymore. Looking closer it seems the whole sieve-funtionality is missing (eg. filtering mails into folders). I am in the process of analysing, and don't have a clue yet. Editing scripts via managesieved works (for example from roundcube). The scripts are in the right place, afai understand. I compare this with another setup where things work and don't see the difference. All this worked perfectly until maybe summer. This is Debian 12.7 bookworm, the dovecot repo still points to bullseye. # cat /etc/apt/sources.list.d/dovecot.list deb [arch=amd64 signed-by=/usr/share/keyrings/dovecot.gpg] https://repo.dovecot.org/ce-2.3-latest/debian/bullseye bullseye main There is rspamd in place with postfix if that is somehow relevant. The installation is on premise and has maybe 60-100 mailboxes in now 2 domains. That was the largest change this year: add a so-called "alias domain" in postfixadmin: mailbox(a)new.domain points to mailbox(a)old.domain I assume the sieve scripts should simply be executed as before. The basics of mailing etc work fine! I'd appreciate any pointers. trying to enable debug logs etc, for example I don't get anything into "sieve_user_log" --- # 2.3.21.1 (d492236fa0): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.21.1 (49005e73) # OS: Linux 6.1.0-26-amd64 x86_64 Debian 12.7 # Hostname: mail2.my.tld auth_cache_size = 4 M default_process_limit = 300 listen = * mail_home = /mnt/mailboxes/%d/%u mail_location = maildir:~ mail_plugins = " notify quota acl" managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate mime foreverypart extracttext imapflags imapsieve vnd.dovecot.imapsieve namespace { inbox = yes location = prefix = separator = / type = private } namespace { location = maildir:/home/vmail/oeffentlich prefix = Oeffentlich/ separator = / subscriptions = yes type = public } passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { acl = vfile:/etc/dovecot/dovecot-acl:cache_secs=300 acl_shared_dict = file:/var/lib/dovecot/shared-mailboxes imapsieve_mailbox1_before = file:/etc/dovecot/sieve/global/learn-spam.sieve imapsieve_mailbox1_causes = COPY imapsieve_mailbox1_name = Spam imapsieve_mailbox2_before = file:/etc/dovecot/sieve/global/learn-ham.sieve imapsieve_mailbox2_causes = COPY imapsieve_mailbox2_from = Spam imapsieve_mailbox2_name = * sieve = /home/vmail/%d/%u/sieve/.dovecot.sieve sieve_before = /etc/dovecot/sieve/global/spam-global.sieve sieve_dir = /home/vmail/%d/%u/sieve/scripts/ sieve_extensions = +imapflags sieve_global_extensions = +vnd.dovecot.pipe sieve_pipe_bin_dir = /usr/bin sieve_plugins = sieve_imapsieve sieve_extprograms sieve_trace_dir = /tmp/sieve_trace/ sieve_trace_level = commands sieve_user_log = /home/vmail/%d/%u/sieve/sieve_user.log } protocols = imap sieve lmtp service auth { client_limit = 1200 unix_listener auth-client { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { mode = 0777 } user = root } service imap-login { process_min_avail = 10 } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0660 user = postfix } user = vmail } service managesieve-login { inet_listener sieve { port = 4190 } } ssl = required ssl_ca = </etc/letsencrypt/pfsense/cloud_imap_mail_smtp_LE_cert.ca ssl_cert = </etc/letsencrypt/pfsense/cloud_imap_mail_smtp_LE_cert.fullchain ssl_cipher_list = ALL:HIGH:!SSLv2:!MEDIUM:!LOW:!EXP:!RC4:!MD5:!aNULL:@STRENGTH ssl_key = # hidden, use -P to show it ssl_key_password = # hidden, use -P to show it userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocol lmtp { mail_debug = yes mail_plugins = sieve postmaster_address = logs(a)my.tld } protocol imap { mail_max_userip_connections = 20 mail_plugins = " notify quota acl imap_sieve imap_acl" } protocol sieve { managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave imapflags }

Issue with logrotate and dovecot
by jim＠themailshack.com 24 Oct '24

24 Oct '24

Something new here has cropped up, no changes to configs for some time. I've had my dovecot using the default /var/log/dovecot.log location for logging, logrotate used to back this up weekly and logging would continue using this same file. Now when logrotate runs, it correctly backs up the log but then creates a new dovecot.log-yyyymmdd file and dovecot starts logging to that. I'm at a loss as to why this is happening. My postfix and other processes are still using their correct log files, so it seems related only to dovecot. From dovecot/conf.d/10-logging.conf: # Log file to use for error messages. "syslog" logs to syslog, # /dev/stderr logs to stderr. #log_path = syslog log_path = /var/log/dovecot.log From /etc/logrotate.d/dovecot /var/log/dovecot.log { weekly rotate 4 missingok notifempty compress delaycompress sharedscripts postrotate doveadm log reopen endscript } Looks like something happened mid last month but other than periodic software updates nothing has changed for a while here. If I reboot the system, dovecot resumes logging to /var/log/dovecot.log, but as soon as logrotate runs (I did a --force to test) it logs to the new file again. Hoping this may sound familiar to someone on the list.

Struggling to get sieve running
by nick＠howitts.co.uk 23 Oct '24

23 Oct '24

Hi, I am new to Dovecot and Debian, but I seem to have got Dovecot up and running with local delivery and then switched to LMTP. I am running Debian 12.7 and Webmin 2.202 to try and get things running, but I've had to tweak files. Also Webmin did not install dovecot-lmtpd, dovecot-sieve or dovecot-managesieved, so I did that manually. I have tried following the configuration guide from Dovecot (but there seems to be little there) and other sources I've found on the internet, but there is nothing I have found to get sieve listening on port 4190 when checked with ss. My Dovecot config from `dovecot -n` is: ``` # 2.3.19.1 (9b53102964): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.19 (4eae2f79) # OS: Linux 6.1.0-26-amd64 x86_64 Debian 12.7 # Hostname: my.fqdn auth_username_format = %Ln disable_plaintext_auth = no first_valid_uid = 1000 mail_location = maildir:~/Maildir mail_privileged_group = mail managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate mime foreverypart extracttext namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } plugin { sieve = file:~/sieve;active=~/.dovecot.sieve } protocols = imap lmtp service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } service managesieve-login { inet_listener sieve { port = 4190 } } ssl_cert = </etc/letsencrypt/live/mydomain.com/fullchain.pem ssl_client_ca_dir = /etc/ssl/certs ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it userdb { driver = passwd } protocol lmtp { mail_plugins = " sieve" postmaster_address = nick(a)mydomain.com } protocol lda { mail_plugins = " sieve" } ``` Dovecot packages installed from the Debian repos are: ``` dovecot-core/stable,stable-security,now 1:2.3.19.1+dfsg1-2.1+deb12u1 amd64 [installed] dovecot-imapd/stable,stable-security,now 1:2.3.19.1+dfsg1-2.1+deb12u1 amd64 [installed] dovecot-lmtpd/stable,stable-security,now 1:2.3.19.1+dfsg1-2.1+deb12u1 amd64 [installed] dovecot-managesieved/stable,stable-security,now 1:2.3.19.1+dfsg1-2.1+deb12u1 amd64 [installed] dovecot-pop3d/stable,stable-security,now 1:2.3.19.1+dfsg1-2.1+deb12u1 amd64 [installed] dovecot-sieve/stable,stable-security,now 1:2.3.19.1+dfsg1-2.1+deb12u1 amd64 [installed] ``` Ultimately I intend to run manage sieve from Roundcube which I have already got running, or I may try a Thunderbird addon. Can anyone give me some pointers, please?

Missing IMAP folders after upgrading from 2.3.17 to 2.3.21.1
by Frank Kirschner 23 Oct '24

23 Oct '24

Hi, I have upgraded from 2.3.17 to 2.3.21.1. mail_location = maildir Now in some mailboxes are IMAP folder in subdir of INBOX missing. When I do a 'ls -la' in filesystem, I see the subfolder like other folder with identical owner an permissions. But when I do doveadm mailbox list -u [user] the IMAP folder is not displayed. So I have deleted all files in /opt/dovecot/[hash]/[user] because I use INDEX=/opt/dovecot/%2.256Nu/%u:ITERINDEX The restart dovecot and re-login the Imap client. All IMAP folders are rebuilt but the same folders like before are still missing.

Uppercase username emails are rejected
by lua8ds＠proton.me 20 Oct '24

20 Oct '24

When a sender writes my email address with my username uppercase, e.g. USERNAME(a)name.com, in the to: field of their MUA, my mail server rejects that email. /var/log/mail.log prints: <USERNAME(a)redacted.com>: host mail.redacted.com[private/dovecot-lmtp] said: 550 5.1.1 > <USERNAME(a)redacted.com> User doesn't exist: USERNAME(a)redacted.com (in reply to RCPT TO > command) In the manual, I found that: auth_username_format Default: %Lu Formatting applied to username before querying the auth database. You can use the standard variables here. Examples: %Lu Lowercases the username [...] My current setting was not the default; I had: auth_username_format = %n So I updated that setting to: auth_username_format = %Lu expecting that %Lu would lowercase the username - and that my problem would be fixed. It does not though. Updating this setting not only prompts my email server to still reject USERNAME(a)redacted.com, but now also rejects (lowercase username) username(a)redacted.com (which my server had no issue receiving beforehand). So I reverted auth_username_format to: auth_username_format = %n Emails sent to username(a)redacted.com land in my mailbox again - but emails sent to USERNAME(a)redacted.com still don't. What can I try to troubleshoot? Which config file shall I share with you?

Piegeonhole and PATH variable
by Julien Salort 18 Oct '24

18 Oct '24

Hello, I have a dovecot-sieve rule that has been working fine for years which calls sa-learn whenever a message is moved from or to the Junk folder. Recently, but I don't know when it started exactly, this no longer works. I get the following error message in mail.log: dovecot: imap: Error: Use of uninitialized value $ENV{"PATH"} in split at /usr/lib/x86_64-linux-gnu/perl-base/File/Spec/Unix.pm line 136. Error: program exec:/usr/lib/dovecot/sieve-pipe/sa-learn-spam.sh (2526990): Forcibly terminated with signal 15 Error: sieve: failed to pipe message to program `sa-learn-spam.sh': refer to server log for more information. [2024-10-16 10:16:51] Error: sieve: Execution of script /usr/lib/dovecot/sieve-pipe/report-spam.sieve failed The content of report-spam.sieve is require ["vnd.dovecot.pipe", "copy", "imapsieve", "environment", "variables"]; if environment :matches "imap.user" "*" { set "username" "${1}"; } pipe :copy "sa-learn-spam.sh" [ "${username}" ]; So my guess is that one of the require on the first line triggers this Unix.pm, and it fails because somehow the PATH variable is not set in this context. However, I am at a complete loss to determine how to change the environment variable in the context of dovecot-sieve. And also, I am not sure why this would be required. Does somebody know how to fix this problem, or alternatively point me to the relevant part in the documentation? Thanks, Julien

Hello, I want to deactivate the auth-system.conf.ext because it slows down the system and makes no sense because I utilize passwdfile.conf.ext. I have put all my configurations into the local.conf file, and all the original configuration files remain untouched. I want to stay on this path because that way I know where I made changes, and updates won't cause me any hassle. But how can I deactivate an option that was activated in the original configuration files?" Jens

last_login plugin does not update IP
by Maciej Polewczyński 11 Oct '24

11 Oct '24

When using the last_login plugin I noticed that the IP address information is not updated. If there is no entry in the sql database for a given user, the first time the login date and time information and the IP address will be saved. Each subsequent login only updates the date and time. The IP address remains unchanged. Example configuration for pop3 service: map { pattern = shared/last-login/pop3/$user/$rip table = last_login value_field = last_pop3_access value_type = uint fields { userid = $user last_pop3_ip = $rip } } This is translated into the following sql command: INSERT INTO last_login (last_pop3_access,userid,last_pop3_ip) VALUES (1727691183673,'test','1.2.3.4') ON DUPLICATE KEY UPDATE last_pop3_access=1727691183673 You can see that after "ON DUPLICATE KEY" only the time is updated. Is there any way to influence the behavior of the plugin and the sql query so that the IP address is also updated? I'm using Dovecot v2.3.4 -- Best regards, Maciej Polewczyński Do or do not. There is no try.

Bug Report: Missing parent folders will cause some clients to not retrieve messages
by Brendon Meyer 09 Oct '24

09 Oct '24

Morning/Evening All, This is a general bug report but it applies to most versions of Dovecot that I have tested to date. I tried to find a previous case where something like this has been reported and for the life of me, I can't find one so if I am duplicating an existing bug report - please let me know. The server platform I am using is FreeBSD 14.1-STABLE (custom build) but that really doesn't have much of a bearing as I was able to recreate the problem on Linux as well as different FreeBSD versions and on different architectures going back as FreeBSD 12 under SPARC). Dovecot version is dovecot-2.3.21_6, but I have tried earlier versions as well and the behaviour is pretty consistent. Apple mail versions are multiple, but in the example I put forward below, I am specifically talking about v12.4 which came with OSX 10.14.6 (last release of Mojave). You get the same behaviour out of later versions of Apple mail that come with later relesaes of OSX/MacOS Thunderbird versions are multiple, but in the example I put forward I am using 115.15.0 (64-bit) under Linux. The behaviour is consistent with earlier versions as well as different platforms (such as Thunderbird on OSX, and Windows). Description of problem: When creating subfolders with tools such as imapfilter, if the parent of the subfolder does not exist, Dovecot will allow that folder to be created, and the tool will allow you to populate that folder with messages. The issue then rears it ugly head when you say use Thunderbird and the messages in this subfolder are not visible. This behaviour is not limited to Thunderbird (e.g. Outlook) but I am using Thunderbird as an example here. Oddly enough, the Apple mail client is *not* impacted in quite the same way (though it is impacted but the behaviour is very subtly different). Allow me to explain with a practical example as to what is happening, and I will parts of my *actual* config here to highlight the issue. I have a imapfilter task that routinely archives messages from the likes of "Sent". Easy enough. It takes each message and drops it in an Archives/sent-mail folder with the year as a parent and then inside that is the subfolders of YYYY-MM with the individual months. So looking at it, it looks something like this: Archives/sent-mail/YYYY/YYYY-MM The generated imapfilter rule that is used looks something like this: sent_202312_bgm = bgm['Sent']:sent_since('01-Dec-2023') * bgm['Sent']:sent_before('01-Jan-2024') sent_202312_bgm:move_messages(bgm['Archives/sent-mail/2023/2023-12']) This is all pretty simple - if the folder "Archives/sent-mail/2023/2023-12" does not exist it will create it and when done, it will then populate the folder with messages from "Sent". The issue is that if the "2023" parent folder does not exist, then some mail clients (as identified above - Thunderbird is an example) will never sync that mail. The workaround is to manually create the YYYY parent folders so that when imapfilter runs and creates the YYYY-MM subfolders then they are visible. I said that Apple mail is a weird edge case example. Its behaviour is not exactly simple or consistent either when missing parent folders, but you at least get some visual idea that something is wrong. Screenshots are probably doing going to come across very well in a forum group but allow me to describe what you see in Apple mail. In Apple mail, if the parent folder exists (for example say I use the year 2019), then see the subfolder in a "grey" colour with the name next to it and all is good. This folder *is* visible to Thunderbird and all the Apple mail functionality works. If the parent folder does *NOT* exist, this is where it gets a little weird. In my example, I have a year of 2023. That parent folder does *NOT* exist. That means that if you look at the Thunderbird view of the Archives/send-mail, you don't see a 2023 parent folder. Apple Mail *DOES* see the parent *BUT* two things are a bit off about it. #1. When you look at the folder in Apple mail, instead of being grey, it appears as a white colour. You can drill into the folder and see the YYYY-MM subfolders inside, but generally it doesn't appear to "work consistently". #2. Searches don't work correctly. Manually renaming the subfolders in Apple mail, then manually creating a parent folder and then moving everything back restores full functionality and also means that other mail clients such as Thunderbird for example will then see all the 2023 subfolders (e.g. 2023-01, 2023-02, etc). So ... is this a bug in Dovecot? If so ... has it been previously reported and if not, do I get a bug named after me? :P /BGM

I am adding a namespace with LAYOUT=index to an existing configuration, and get this notification: LAYOUT=index requires mailbox_list_index=yes Maybe better to just not risk it and add LAYOUT=fs to my existing mail_location=mdbox: lines?

Namespace for seperate Storage of Archive
by Christian Großegger 05 Oct '24

05 Oct '24

Hi everyone, I found the Solution myself. The key was to simply create an unnamed mailbox directive so that the namespace prefix directly results into an mailbox that Thunderbirds shows as the Archive. Thanks everbody on the dovecot team for making such a brilliant Software! Greetings! Christian namespace inbox { inbox = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Junk { auto = subscribe special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } prefix = separator = / } namespace archivns { prefix = Archive/ <--- this is the Name which now appears at the same Level then Sent/Draft/... location = maildir:/mnt/mails2/%u separator = / mailbox { <--- here a name is omitted auto = subscribe special_use = \Archive } }

dovecot/Pigeonhole sieve sets seen flag
by Hadmut Danisch 04 Oct '24

04 Oct '24

Hi, I'm using dovecot, running Ubuntu 24.04 with dovecot 1:2.3.21+dfsg1-2ubuntu6 and postfix. Since Ubuntu dropped mailfilter for 24.04, I am replacing mailfilter with the sieve filter. Problem/Question: I am using something like if header :matches "Subject" "htest" { addflag "$label1"; fileinto :create "Test.${year}.${month}"; stop; } following https://doc.dovecot.org/2.3/configuration_manual/sieve/examples/ which works, but not as expected: When having the addflag, the mail is delivered as seen, i.e. put in the /cur directory of the Maildir folder. Without the addflag, it is put into /new , where it belongs to (as unseen). Why does addflag "$label1"; mark the Mail as seen? regards Hadmut (please respond directly, I am not on this list)

Helping doveadm sync detect moves between Maildir mailboxes? (reproducible example of bad behaviour)
by falsifian＠falsifian.org 02 Oct '24

02 Oct '24

Hi, Moving mail files between Maildir mailboxes often confuses doveadm sync: I end up with copies in both the original and new maildir. Exact details and script to reproduce follow. I can work around this by running doveadm move, but it does not fit well with my workflow, which is based on paths to mail files (using mblaze as my mail client). Two questions: 1. Is there anything I can do to help dovecot notice the moves, other than using doveadm move instead of just mv? I have tried liberal use of force-resync but the problem is still there. 2. Is this a bug? Details: OS: OpenBSD current $ dovecot --version 2.3.21.1 (d492236fa0) config: My repro script below uses a one-line config, only setting mail_location. (An OpenBSD 7.5 server running Dovecot 2.3.21 is involved in my real setup, but I was able to reproduce it locally without the server involved.) To reproduce: (shell script follows) - Make two maildirs "a" and "b", each with a subfolder ".Archive". - Manually write a mail file to a/cur. - doveadm sync - force-resync everything - manually move the file to a/.Archive/cur - force-resync everything again - doveadm sync - Now the mail file appears four times: in a, a/.Archive, b, and b/.Archive. Script to do the above follows my signature. -- James #!/bin/sh set -e # Run in a new directory with two maildirs named a and b and a simple config. mkdir bug; cd bug mkdir -p {a,b}/{,.Archive/}{cur,new,tmp} cat > dovecot.conf <<EOF mail_location=maildir:$PWD/a EOF # Deliver an email and sync. EXAMPLE_ID=12345.R67890.example.com cat > a/cur/$EXAMPLE_ID:2, <<EOF some email EOF doveadm -c dovecot.conf sync maildir:b # Move the email and sync again. Run force-resync between steps in case it helps. doveadm -c dovecot.conf force-resync INBOX doveadm -c dovecot.conf force-resync Archive doveadm -c dovecot.conf -o mail_location=maildir:$PWD/b force-resync INBOX doveadm -c dovecot.conf -o mail_location=maildir:$PWD/b force-resync Archive mv a/cur/$EXAMPLE_ID* a/.Archive/cur doveadm -c dovecot.conf force-resync INBOX doveadm -c dovecot.conf force-resync Archive doveadm -c dovecot.conf -o mail_location=maildir:$PWD/b force-resync INBOX doveadm -c dovecot.conf -o mail_location=maildir:$PWD/b force-resync Archive doveadm -c dovecot.conf sync maildir:b echo in a: doveadm -c dovecot.conf -fflow fetch 'mailbox guid' all echo echo in b: doveadm -c dovecot.conf -fflow -o mail_location=maildir:$PWD/b fetch 'mailbox guid' all

Namespace for seperate Storage of Archive
by Christian Großegger 30 Sep '24

30 Sep '24

Hi everyone, I would like to move the "Archives" Folder for every user from my default storage to another storage in the backend, while maintaining the current frontend view of the IMAP Mailboxstructure. Because I didn't manage to get it to work properly on my production server, I made a separate Testserver. My problem is, that I don't know what to put in the "prefix" section of the Namespace, so that the Archive Folder is on the same folder/mailbox hierarchy level as the ones in the default namespace (Sent Messages, Drafts ...). I have read the Namespace RFC (rfc2342) and there is one example which uses the Tilde ~ Character as the Namespace prefix - put the rfc doesn't address the tilde, it only has it in one of the examples (Example 5.4). Because ~ often means 'base folder' I thought this would work. But it doesn't. The Thunderbird client shows: Rootdir/Sent but Rootdir/~/Archive I am aware I can solve this with symlinks, but I would like to do it properly with namespaces. Could you please tell me what I am missing? In case this is an Thunderbird Issue, could you please point out, what I don't understand? Thank you!

Remove hard-coded paths in doc/solr-config-9.xml
by Saman Ghannadzadeh 30 Sep '24

30 Sep '24

Hi, Dovecote includes a config file for use with Solr 9, at 'doc/solr-config-9.xml'. However, this file has two problems: - it hard codes the path to the Solr installation - it hard codes version numbers of Icu/Lucene packages This issue can be be easily fixed by using the '${solr.install.dir}' variable in that config file. The attached patch will fix both issues. Best wishes, Saman Ghannadzaded diff -crB a/doc/solr-config-9.xml b/doc/solr-config-9.xml *** a/doc/solr-config-9.xml 2024-09-29 20:50:42.873229769 +0100 --- b/doc/solr-config-9.xml 2024-09-29 20:58:53.507638810 +0100 *************** *** 75,82 ****   ! <lib dir="/opt/solr/modules/analysis-extras/lib" regex="icu4j-70.1.jar"/> ! <lib dir="/opt/solr/modules/analysis-extras/lib" regex="lucene-analysis-icu-9.8.0.jar"/>   ! <lib dir="${solr.install.dir}/modules/analysis-extras/lib" regex="icu4j-.*\.jar"/> ! <lib dir="${solr.install.dir}/modules/analysis-extras/lib" regex="lucene-analysis-icu-.*\.jar"/> <!-- an exact 'path' can be used instead of a 'dir' to specify a specific jar file.

TLS certificates SQL driver ?
by Andrew Mason 28 Sep '24

28 Sep '24

Hi folks, I was curious if it was possible to configure Dovecot to lookup the TLS certificate it should present in a similar way that the passdb lookups can use a driver. I have a few domains that share the same IP and I'm currently using SNI with both Dovecot and Postfix. I have pretty much all the configuration stored for each domain in a relational database , including the TLS cert that Postfix presents. If I add a new domain, I still have to add an entry to config file for dovecot i.e local_name imap.example.org { ssl_cert = </etc/ssl/certs/imap.example.org.crt ssl_key = </etc/ssl/private/imap.example.org.key } local_name imap.example2.org { ssl_cert = </etc/ssl/certs/imap.example2.org.crt ssl_key = </etc/ssl/private/imap.example2.org.key } I was hoping it was possible to use the same records in the database that I currently use for Postfix. Kind regards Andrew

Dovecot undeleteable folder?
by Benoît Panizzon 27 Sep '24

27 Sep '24

Hi Liste We are and ISP and use Dovecot. From time to time, we have customer reporting not being able to delete IMAP folder they have created. This often seems to happen when some email client is creating temporary folder on some move or copy operations. Permissions look right. I can't figure out, what goes wrong, but I can reproduce via telnet by manually issuing IMAP commands. To me it looks like Dovecot forgets about what folders exist. Is there some caching of the folder information? Is there a way to enable some debug logging of folder creation and deletion? Example: Customer has a Folder named: ARCHIV.AdministrationXXX Folder file exists and permissions look right: ./ARCHIV/AdministrationXXX d delete ARCHIV.AdministrationXXX d OK Delete completed (0.001 + 0.000 secs). Folder file is still present and can not be deleted again. Re-Connecting with a client lists the folder as present despite having been deleted. It's sort of a Schrödinger Folder. It is there but it's also not there. c create ARCHIV.AdministrationXXX c OK Create completed (0.007 + 0.000 + 0.006 secs). d delete ARCHIV.AdministrationXXX d OK Delete completed (0.006 + 0.000 + 0.005 secs). Now the Folder File is gone, showing the permissions were correct. I can do this corrective action via telnet. But most mail clients will refuse to create a Folder with the same name as an existing one. What could cause that issue and how I could try to further debug the issue? No errors, no hints in the logs. -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________

hello I encountered the following issue while compiling Dovecot on a Linux system with the Shenwei architecture in China using RPM: During the build phase, it shows: Copy Code checking whether fd passing works... no configure: error: fd passing is required for Dovecot to work The version of Dovecot I am compiling is 2.3.16, and the version of the GCC tool is 8.5.0.

dsync with vurtial folder leads to mess of msg ID
by Kirill A. Korinsky 25 Sep '24

25 Sep '24

Greetings, I have a setup with two dovecot servers and dsync replication between them. On both of them I have a virtual folders, forexample All with config: mx1# cat /etc/dovecot/virtual/All/dovecot-virtual * -Trash -Trash/* -Junk -Junk/* all All virtual folders are excluded from replication because it leads to broken replication with errors like: virtual.All can't be created. So, I have. replication_dsync_parameters = -d -l 30 -U -x virtual. Unfortently, after a couple of weeks I've noticed that msg id for the same message on the different servers aren't match. For example: mx1# doveadm fetch -u kirill(a)korins.ky 'uid' mailbox virtual.All header Message-ID 'macports/macports-ports/pull/22284/c1901369454(a)github.com' uid: 157786 mx1# doveadm fetch -u kirill(a)korins.ky 'uid' mailbox INBOX header Message-ID 'macports/macports-ports/pull/22284/c1901369454(a)github.com' uid: 5561 mx1# vs mx2# doveadm fetch -u kirill(a)korins.ky 'uid' mailbox virtual.All header Message-ID 'macports/macports-ports/pull/22284/c1901369454(a)github.com' uid: 157766 mx2# doveadm fetch -u kirill(a)korins.ky 'uid' mailbox INBOX header Message-ID 'macports/macports-ports/pull/22284/c1901369454(a)github.com' uid: 5561 mx2# as you may see msgid at INBOX are matched, but it isn't true for virtual.All, here 157786 vs 157766 So, here the question: how can I sync msg id inside virtual folder on this setup? -- wbr, Kirill

by Marc 24 Sep '24

24 Sep '24

I am trying to modify the body of message with a global sieve script. It looks like that sieve-test does not generate this error, however I am not really able to verify the output. There does not seem to be an option to catch the output (new message) trace log 00000008: 3: finishing match with result: matched 00000029: 3: jump if result is false 00000029: 3: not jumping 0000002e: 5: filter action 0000002e: 5: execute program `sieve-command' 0000002e: 5: filter action: program indicated false result 0000005f: ## Finished executing script 'commands' require ["vnd.dovecot.execute","vnd.dovecot.filter","vnd.dovecot.debug"]; #if true if header :contains "Subject" "xxxx" { filter "sieve-command" ["-task","xxxx"]; } dovecot log (1166226): Terminated with non-zero exit code 2

bug dir copy group permissions?
by Marc 23 Sep '24

23 Sep '24

I am not sure if this page is correct, looks at least like this g+s not ok https://doc.dovecot.org/2.3/admin_manual/filesystem_permission/ work-around is to manually create dirs mdbox mdbox/storage mdbox/mailboxes. I would think this is a bug as files seem to be created correctly. group rights are not copied on directories, resulting in getfacl #effective:--- for the acl groups just testing with rm -R -f everything below usertest6 [@ shared]# ls -ln total 4 drwxr-xr-x 4 0 0 34 Sep 23 11:50 bak drwxrwx---+ 4 10001 10001 34 Sep 23 12:18 usertest drwxrwx---+ 3 10002 10002 19 Sep 23 11:51 usertest2 drwxrwx---+ 3 10006 10006 19 Sep 23 12:37 usertest6 -rw-r--r-- 1 0 0 121 Sep 23 11:46 README where are the group rights on mdbox?

Mail Backup from IMAP to POP3
by Reprobus 22 Sep '24

22 Sep '24

Hi, I'm in a situation whereas I need to backup my email from an IMAP server to a POP3 email client of my choosing. I'm hoping Dovecot can do such a task and is there a container to which I can run to set this up from ? My IMAP email server is maxed and I need to dump all the emails off the IMAP to POP3 as to clear it up. Thank You

shared mailbox not visible, acl_shared_dict stays empty
by Marc 22 Sep '24

22 Sep '24

I am creating the mailbox like this: doveadm -o mail_gid=testgroup2 mailbox create -u usertest shared/sharedtest1 I can set acl's (I think), at least the acl get produces the same. doveadm acl set -u usertest shared/sharedtest1 user=usertest6 lookup read write write-seen insert post doveadm acl get -u usertest shared/sharedtest1 However this file stays empty, I have read somewhere it should automatically be updated? acl_shared_dict = file:/tmp/shared-mailboxes.db How should I add entries manually there with: doveadm dict set file:/tmp/shared-mailboxes.db shared/sharedtest2 kempotest6 or with this syntax still???? https://www.dovecot.org/list/dovecot/2009-April/038922.html

public mailbox filesystem layout + permission best practice
by Marc 22 Sep '24

22 Sep '24

I have some issues testing public mailboxes with linux users and groups creating mailboxes for users for the first group is not really a problem: doveadm -o mail_gid=testgroup2 mailbox create -u usertest public/publictest1 doveadm -o mail_gid=testgroup2 mailbox create -u usertest6 public/publictest2 doveadm -o mail_gid=testgroup2 mailbox create -u usertest2 public/publictest3 If I remove usertest6 from testgroup2 roundcube instantly stops showing these mailboxes. However when I try to make a new public mailbox with a different group. I am getting errors. doveadm -o mail_gid=testgroup3 mailbox create -u usertest6 public/publictest4 missing +r perm: public/mdbox/storage/dovecot.map.index.log public/mdbox/storage/dovecot.map.index.log, we're not in group I have the impression I am doing something wrong here, maybe configure the namespace with different filesystem layout? I assume it is possible to work with multiple groups in one public namespace? public/ └── mdbox ├── dovecot.list.index.log ├── dovecot-uidvalidity ├── dovecot-uidvalidity.66f00cc7 ├── mailboxes │ ├── publictest1 │ │ └── dbox-Mails │ │ ├── dovecot.index.cache │ │ └── dovecot.index.log │ ├── publictest2 │ │ └── dbox-Mails │ │ ├── dovecot.index.cache │ │ └── dovecot.index.log │ ├── publictest3 │ │ └── dbox-Mails │ │ └── dovecot.index.log │ └── testthunderbird │ └── dbox-Mails │ ├── dovecot.index.cache │ └── dovecot.index.log └── storage └── dovecot.map.index.log namespace public { disabled = no type = public separator = / prefix = public/ location = mdbox:/home/popusers/public/mdbox list = yes subscriptions = no }

sieve combine or not to be combine ?
by Marc 21 Sep '24

21 Sep '24

I am cleaning a bit my sieve scripts and wondered if I should stick to this solution sieve_before = sieve_before2 = sieve_before3 = or just one sieve_before = and put all scripts in this one. What are the advantages / disadvantages of doing this?

indexer: Error: conn unix:indexer (pid=562491,uid=10003): didn't reply with a valid VERSION line
by phren＠ist-einmalig.de 20 Sep '24

20 Sep '24

Hi, A few weeks ago we moved our mailserver to a new location. On the new location we use now dovecot v2.3.19.1 insteadof v2.3.4.1. We moved the mailboxes by zipping all mailbox on the old location and unzip on the new location. Now we see an indexer error quite often: > indexer: Error: conn unix:indexer (pid=563158,uid=10005): didn't reply with a valid VERSION line: 1 0 indexer indexer Sometimes when we try to use the index for searching we just get no results. We can't really find a cause for this error on the internet. As solution we found "Just do a re-indexing." Ok, but what may cause this error? And how can we prevent this error in the future? As indexer we use lucene. Any hint is appreciated. -- Phren

In case etc. there's alias from domainA to domainB which results in lmtp delivery with both recipients submitted in the same "lmtp session" as "batch", it seems that only one delivery happens, as by the time zlib plugin kicks in - effective user id for the process is already set to second delivery user which fails zlib(at least disabling that/removing it from mail plugins delivery/save is successful). I know that it can mitigate by modifying (in this case exim's) conf and setting batch_max to 1, which results in single submit(single RCPT TO), though still curious if that's by design? What I guess is asynchronous compression ? Or that would be considered a bug? Best Regards

Therefore, whenever got, you could go facing silly outcomes like besieging the course, scholarly suspension or even send off. To this end picking a fair relationship with a showed history is crucial. The association is clear: present your mentioning and survey offers from qualified educated authorities.

Unfortunately, there are many tricks that confirmation to take online courses for you. These affiliations charge ridiculous totals and don't complete their obligations. They may also hand you over to your school. Tolerating that they do, you could be killed from your underwriting project or even suspended or removed from school.

They may comparatively have the decision to help you with beating any learning handicaps you have. Copyright infringement suggests utilizing someone else's words and thoughts without their endorsement. It is viewed as a kind of cheating and can accomplish a delicate grade or even send off from school. It is difficult to ensure that a used professional won't phony.

There's no veritable strategy for remaining caution assuming the solitary you enroll to take your online course will tell the truth and dependable. They probably won't be in a tantamount state as you. Moreover, they apparently won't be as dedicated to finishing the class for you as you are. They may very well be doing the base extent of work expected to get reviewed and a brief time frame later vanish.

Correct permissions for global sieve scripts
by Richard 16 Sep '24

16 Sep '24

Hi there, I've set up dovecot via global sieve scripts to send mails that a user manually moved to their junk directory to rspamd to learn them as spam (and learn messages as ham if they are moved out of it). I thought I had it all properly set up, but I'm now again seeing log messages like this: Sep 15 13:01:00 dovecot[523226]: imap(username)<823661><4+8RXyYi2L9/AAAB>: Error: sieve: failed to execute to program `rspamd-learn-spam.sh': refer to server log for more information. [2024-09-15 13:01:00] Sep 15 13:01:00 dovecot[523226]: imap(username)<823661><4+8RXyYi2L9/AAAB>: Error: sieve: Execution of script /etc/dovecot/sieve/global/learn-spam.sieve failed The content of learn-spam.sieve is this: require ["vnd.dovecot.pipe", "copy", "imapsieve"]; pipe :copy "rspamd-learn-spam.sh"; And the content of rspamd-learn-spam.sh is this: #!/bin/sh exec /usr/bin/rspamc learn_spam All the necessary files are located in /etc/dovecot/sieve/global and are owned by dovecot:dovecot with rw, r, r permissions. Also, I have compiled the .sieve files with sievec, the resulting .svbin files have the same permissions and ownership. What am I doing wrong? I don't see any further "server log" that will tell me more information. I'm using dovecot 2.3.19.1 (9b53102964) on Debian 12.7 Best Richard

Allowing parallel read-only requests via doveadm http api
by Kevin Kelker 16 Sep '24

16 Sep '24

Hi, is there any chance to open the doveadm http api to handle more than one client at a time if the requests are read-only commands that have no risk of breaking something when they run simultaneously? We have a scenario of using it only for getQuota to visualize a live-status of the mailbox usage but every once in a while, there are more than one parallel requests for that that are then getting tcp connection resets. As far as I've seen it in https://dovecot.org/mailman3/archives/list/dovecot@dovecot.org/thread/PYMMJ… spawning another doveadm http api service with another port wouldn't do the trick. If that's not possible, wouldn't be a failure code as a response a more clean approach than just refusing the connection at all? Right now, it's getting logged on the dovecot backend as "doveadm server can handle only a single client" but the requesting client gets a connection reset instead of a json-type response with a failure code.

Selectively query folders for new emails
by Habakuk Tibatong 12 Sep '24

12 Sep '24

Hi folks, I have two questions: - Is it possible to exclude folders from being queried for new emails? I have many folders in my maildir, each of which has many sub-folders, with many sub-sub-folders. My Thunderbird logs in and then queries one folder after the other and this takes a very long time. However, there are only 5 folders into which I automatically sort emails with sieve, and I would like to query only these 5 folders. The other folders are folders into which I sort emails manually. It makes no sense to query them. How could I achieve this? - How can I exclude folders from being displayed in the subscribe window, i.e. that these folders exist, e.g. they are available but cannot be subscribed to, and therefore cannot be displayed in the email client? I plan to introduce a all-times "non-deletable" spam folder, which contains a copy of all spam emails that this user received and which I use to teach spamassassin, without the user being able to see, empty or delete this folder, and without him being able to infect himself with potentially infected emails.

Hi all, we are releasing a CVE patch release 2.3.21.1. https://dovecot.org/releases/2.3/dovecot-2.3.21.1.tar.gz https://dovecot.org/releases/2.3/dovecot-2.3.21.1.tar.gz.sig Binary packages in https://repo.dovecot.org/ Docker images in https://hub.docker.com/r/dovecot/dovecot Kind regards, Aki Tuomi Open-Xchange oy --- - CVE-2024-23184: A large number of address headers in email resulted in excessive CPU usage. - CVE-2024-23185: Abnormally large email headers are now truncated or discarded, with a limit of 10MB on a single header and 50MB for all the headers of all the parts of an email. - oauth2: Dovecot would send client_id and client_secret as POST parameters to introspection server. These need to be optionally in Basic auth instead as required by OIDC specification. - oauth2: JWT key type check was too strict. - oauth2: JWT token audience was not validated against client_id as required by OIDC specification. - oauth2: XOAUTH2 and OAUTHBEARER mechanisms were not giving out protocol specific error message on all errors. This broke OIDC discovery. - oauth2: JWT aud validation was not performed if aud was missing from token, but was configured on Dovecot.

What would be the effect of deleting EVERYTHING in .imap.... will it just get recreated as needed? or do I need to take care and only remove stuff I know is no longer used?

Can I delete duplicate messages under Maildir on the server?
by MI 05 Sep '24

05 Sep '24

After a client misconfiguration, many messages have been deleted. I restored them from backups, but now there are many duplicates. I can identify them on the server, and delete them. But do I need to also delete the dovecot.index files and/or other dovecot* files in the affected folders, or will these be automatically updated? (My Dovecot version is 2.3.13, so I guess I should not use doveadm deduplicate which would risk deleting non-duplicate messages, according to the "doveadm-deduplicate deletes non-duplicates" thread here?)

allow_nets check failure still performs LDAP bind authentication
by Florian Wunderlich 04 Sep '24

04 Sep '24

Postfix authentication via Dovecot. Dovecot performs the allow_nets check, which fails. It then still attempts to authenticate the user via LDAP bind, thus allowing DoS attacks where the entry in the directory will be locked after a few failed attempts. dovecot --version: 2.3.19.1 (9b53102964) Debian GNU/Linux 12 (bookworm), x86, no NFS Sep 04 07:26:05 postfix/smtpd[48225]: connect from unknown[182.176.211.10] Sep 04 07:26:17 dovecot[33863]: auth: *ldap(XXX,182.176.211.10): allow_nets check failed: IP 182.176.211.10 not in allowed networks* Sep 04 07:26:17 dovecot[33863]: auth: *ldap(XXX,182.176.211.10): Password mismatch (for LDAP bind)* Sep 04 07:26:27 postfix/smtpd[48225]: warning: unknown[182.176.211.10]: SASL LOGIN authentication failed: Connection lost to authentication server, sasl_username=(unavailable) Sep 04 07:26:27 postfix/smtpd[48225]: lost connection after AUTH from unknown[182.176.211.10] Sep 04 07:26:27 postfix/smtpd[48225]: disconnect from unknown[182.176.211.10] ehlo=2 starttls=1 auth=0/1 commands=3/4 The allow_nets extra field comes from LDAP. This works as a pass_filter query is performed first, which returns the allow_nets. /DN is looked up by sending a pass_filter LDAP request and getting the DN from the reply. This is very similar to doing a password lookup. The only difference is that userPassword attribute isn’t returned. Just as with password lookups, the pass_attrs may contain special extra fields./ https://doc.dovecot.org/2.3/configuration_manual/authentication/ldap_bind/#… After this, Dovecot should immediately fail the authentication. /If the user tries to log in from elsewhere, the authentication will fail the same way as if a wrong password was given./ https://doc.dovecot.org/2.3/configuration_manual/authentication/allow_nets/ There is no need to perform the bind authentication. According to the log (and the locked user accounts), it is still performed. Configuration is irrelevant, for completeness’s sake: auth_bind = yes pass_filter = (&(|(objectClass=simpleSecurityObject)(objectClass=posixAccount))(cn=%n)) pass_attrs = \ cn=user, \ allowNets=allow_nets

Inconsistency in map index with dovecot v2.3.21

Hello, We have been running dovecot version 2.3.21 since July on debian bookworm system. After upgrading we have seen in the logs similar messages to the following: 2024-08-29T19:33:27.755399+03:00 server1 dovecot: lmtp(user1(a)modulus.gr)<481240><7TMeHNei0GYpeTkA1g8ogQ:P1>: Warning: mdbox /path/user1/mdbox/storage: Inconsistency in map index (2213,40 != 2213,56). 2024-08-29T19:33:27.755399+03:00 server1 dovecot: lmtp(user1(a)modulus.gr)<481240><7TMeHNei0GYpeTkA1g8ogQ:P1>: Warning: mdbox /path/user1/mdbox/storage: Inconsistency in map index (2213,40 != 2213,56) 2024-08-29T19:33:27.838990+03:00 server1 dovecot: lmtp(user1(a)modulus.gr)<481240><7TMeHNei0GYpeTkA1g8ogQ:P1>: sieve: msgid=<39f9c444-0c08-4bda-bfc9-512c34584470(a)modulus.gr>: fileinto action: stored mail into mailbox 'Replies' 2024-08-29T19:33:27.840222+03:00 server1 dovecot: lmtp(user1(a)modulus.gr)<481240><7TMeHNei0GYpeTkA1g8ogQ:P1>: Warning: fscking index file /path/user1/mdbox/storage/dovecot.map.index 2024-08-29T19:33:27.953281+03:00 server1 dovecot: lmtp(user1(a)modulus.gr)<481240><7TMeHNei0GYpeTkA1g8ogQ:P1>: Warning: mdbox /path/user1/mdbox/storage: rebuilding indexes 2024-08-29T19:37:27.989792+03:00 server1 dovecot: lmtp(user1(a)modulus.gr)<481249><vhzsLROj0GYQVgcAfAk26A:P1>: Error: Timeout (180s)while waiting for lock for transaction log file /path/user1/mdbox/storage/dovecot.map.index.log (WRITE lock held by pid 481240) 2024-08-29T19:37:27.995913+03:00 server1 dovecot: lmtp(user1(a)modulus.gr)<481249><vhzsLROj0GYQVgcAfAk26A:P1>: Error: sieve: msgid=<39f9c444-0c08-4bda-bfc9-512c34584470(a)modulus.gr>: fileinto action: failed to store into mailbox 'Mailbox': Timeout (180s) while waiting for lock for transaction log file /path/user1/mdbox/storage/dovecot.map.index.log (WRITE lock held by pid 481240) This has happened a few times since we upgraded always by a lmtp process. It seems to be happening randomly and we have not been able to reproduce it. The mailboxes are stored in a glusterfs server, and we use the dovecot director with shared mailboxes architecture. Usually this was mitigated automatically by dovecot index rebuilding, but last time it happened on a mailbox with a lot of giga byte of mail data the following logs were produced for more than an hour: 2024-08-29T19:45:30.506694+03:00 server1 dovecot: lmtp(user1(a)modulus.gr)<481240><7TMeHNei0GYpeTkA1g8ogQ:P1>: Error: mmap_anon(/path/user/mdbox/mailboxes/Mailbox/dbox-Mails/dovecot.index.cache, 74076160) failed: Cannot allocate memory During that period segfaults starting being generated for the imap processes accessing that mailbox probably caused by timeouts from imap processes attempting to fetch emails from the affected mailbox: [3912187.557029] imap[481783]: segfault at 38 ip 00007fb03248abf8 sp 00007ffc88b264f0 error 4 in libdovecot-storage.so.0.0.0[7fb0323c7000+d8000] likely on CPU 6 (core 3, socket 0) What might be the reason that inconsistency of the map index is introduced on random users? We have seen some other users had similar issues and have mentioned them on this mailing list(dovecot Digest, Vol 249, Issue 4, dovecot Digest, Vol 250, Issue 8)? Is there any update for a mitigation or bug confirmation for dovecot version 2.3.21 that might be responsible? Thank you, Nikos Pyrgiotis

Fwd: maintainer-feedback requested: [Bug 280929] mail/dovecot move bogus warning "Time moved forwards" to debug

Comments from the dovecot community? Aug 19, 2024 11:07:30 AM bugzilla-noreply(a)freebsd.org: Bugzilla Automation <bugzilla(a)FreeBSD.org> has asked Larry Rosenman <ler(a)FreeBSD.org> for maintainer-feedback: Bug 280929: mail/dovecot move bogus warning "Time moved forwards" to debug https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=280929 --- Description --- Dovecot complains about time moving forward, which seems to be due to a broken mechanism (on FreeBSD) used to measure timeouts. This warning spams the maillog up to several hundred times per day. There's an ongoing thread about this issue in the freebsd forums: https://forums.freebsd.org/threads/dovecot-time-moved-forwards.82886 In post #33 RypPn points out the offending line in main.c and in post #34 msplsh suggests instead of completely removing/commenting out the line, it would be more sensible to move it from 'warning' to 'debug'. This is what this patch does: change the log facility to 'debug' to mute that bogus message for standard configurations, but keep it in 'debug' for anyone who might want to debug that issue in the future. I tested the patch as a local patch in poudriere and it builds fine on 13.3-RELEASE with the quarterly and latest branch.

Hi, I've seen a few emails over the years related to this error message, but they are typically associated with doveadm. In my case, it's related to dovecot itself.

The main config was copied over from another dovecot system on fedora37 with virtually identical settings, including the same SSL cert.

Dovecot with LDAP and Solr: Force Solr user key
by Michele Giacomoli 27 Aug '24

27 Aug '24

Good morning everyone. I am configuring dovecot with ldap and solr as fts plugins. The LDAP configuration works correctly and users can log in both via the userPrincipalName attribute and via mail. In this configuration the LDAP realm and the email domain differ, and on the server the LDAP realm domain is privileged. This means that the mail dir is located in ./ldap_realm/username and in the same way postfix delivers the emails to dovecot using username@ldap_realm as envelope recipient. Consequently the emails are indexed on solr using "username@ldap_realm" as user key. However if I log in in imap using the email address as username and try to do some searches dovecot sends a select to solr using the email address as key and not the ldap user, and consequently I do not get any results from the search. So my question is: is it possible to configure dovecot to force queries to solr so that "username@ldap_realm" is always used as the key even when logging in via email? Dovecot version is: 2.3.7.2 Solr version: 7.2.1 Ldap configuration: [...] user_filter = (&(|(userPrincipalName=%u)(mail=%u))(objectClass=person)(!(userAccountControl=514))(memberOf=cn=Mail,ou=Groups,dc=example,dc=org)) pass_filter = (&(|(userPrincipalName=%u)(mail=%u))(objectClass=person)(!(userAccountControl=514))(memberOf=cn=Mail,ou=Groups,dc=example,dc=org)) pass_attrs = userPassword=password user_attrs = =home=/data/mail/%Ld/%Ln/Maildir/,=mail=maildir:/data/mail/%Ld/%Ln/Maildir/ Solr configuration: plugin { fts = solr fts_solr = url=http://solr_host:8983/solr/dovecot/ fts_autoindex=yes } Best regards -- Logo Mynet *Michele Giacomoli* Reparto IT 32.000 km di fibra ottica nel nord Italia al servizio delle aziende *www.mynet.it* <https://www.mynet.it/> - *www.vogliadifibra.it* <https://www.vogliadifibra.it/>

2.3.21(.1) build error on aarch64 (using slackware ARM -current)
by shawn.kubik＠shaw.ca 22 Aug '24

22 Aug '24

I've spent the last week trying to rebuild Dovecot on my Raspberry Pi 3 (aarch64; running Slackware ARM -current) and am running into the following build error. I suspected it may be my recent update to Slackware but I've been able to build the same source tarball on an x86 system running slackware64-current without any problems, so it *seems* specific to aarch64. I've tried both building from the 2.3.21 (and 2.3.21.1) tarball(s) as well as pulling the latest code from github and they all fail similarly, though in different spots it appears. I am building from source instead of using the available Slackware packages bc those packages don't have support for postgresql built in, but has mysql/mariadb support, which I am not using and is not installed on my systems. While it does run, when I try to connect to it, it fails citing a missing mariadb.so file. gcc -v output: Reading specs from /usr/lib64/gcc/aarch64-slackware-linux-gnu/14.2.0/specs COLLECT_GCC=gcc COLLECT_LTO_WRAPPER=/usr/libexec/gcc/aarch64-slackware-linux-gnu/14.2.0/lto-wrapper Target: aarch64-slackware-linux-gnu Configured with: ../configure --with-arch=armv8-a --verbose --prefix=/usr --mandir=/usr/man --infodir=/usr/info --libdir=/usr/lib64 --enable-bootstrap --enable-checking=release --enable-libstdcxx-dual-abi --enable-shared --enable-languages=ada,c,c++,d,fortran,go,lto,m2,objc,obj-c++,rust --enable-objc-gc --enable-threads=posix --enable-__cxa_atexit --enable-gnu-unique-object --enable-clocale=gnu --enable-plugin --enable-lto --with-arch-directory= --with-system-zlib --with-gnu-ld --with-isl --with-default-libstdcxx-abi=new --disable-libunwind-exceptions --disable-libstdcxx-pch --disable-libssp --disable-werror --disable-gtktest --disable-install-libiberty --host=aarch64-slackware-linux-gnu --build=aarch64-slackware-linux-gnu --target=aarch64-slackware-linux-gnu Thread model: posix Supported LTO compression algorithms: zlib zstd gcc version 14.2.0 (GCC) ldd --version output: ldd (GNU libc) 2.40 Copyright (C) 2024 Free Software Foundation, Inc.

Hi, From what I understood from the archive and from my tests, we cannot have multiple passwords for a given account. (I get the error: Password query returned multiple matches) But it looks like it can be done via a PAM module. Does anyone succeeded setup multiple password with PAM or any other method with a SQL backend ? Regards, Aubry

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.

Is this a MacOSX client? I think they have a habit of doing this when doing global mailbox searches. Instead of doing a sane serial march through mailboxes, it opens up as many mailboxes as it can, then closes them when the IMAP server denies then when they hit the max. If Aki doesn't can't offer a solution, neither can I, but maybe you can play around with mail_max_userip_connections to stop them from swamping all your connections. You might have to resort to firewall or other general network controls to actually rate limit connections. Joseph Tam <jtam.home(a)gmail.com>

The future of SIS
by Sebastian Marsching 16 Aug '24

16 Aug '24

Hi, I am currently in the process of planning a new deployment of Dovecot. I was planning to use mdbox or sdbox with “mail_attachment_fs = sis posix”, but I stumbled across the following notice in the documentation for Dovecot 3.0 (https://doc.dovecot.org/3.0/settings/core/#core_setting-mail_attachment_fs) > Changed in version 2.4.0 (CE): SIS is deprecated and writing of SIS files is disabled. Reading is supported for now, any missing SIS attachments are replaced with files filled with spaces. > > Changed in version 3.0.0 (Pro): SIS is deprecated and writing of SIS files is disabled. Reading is supported for now, any missing SIS attachments are replaced with files filled with spaces. And https://doc.dovecot.org/3.0/installation_guide/upgrading/from-2.3-to-3.0/ says: > Saving new mails’ attachments via fs-sis is disabled, but reading SIS attachments is still supported. Missing SIS attachments are replaced with files filled with spaces. What is not entirely clear from this comment is whether this only applied to “sis posix” or also to “sis-queue posix”. Does anybody whether sis-queue is also affected by this? I saw that the notice was added to the dovecot/documentation Git repository in April 2023, but I couldn’t find any further information there or the main branch of the dovecot/core repository. Maybe, the code for 2.4 / 3.0 has not made it into that branch or repository yet. SIS sounds like a neat concept and I would like to use it, but obviously I do not want to use a soon-to-be-deprecated feature in a completely new deployment. So, does anybody know an alternative solution for attachment deduplication (except file-system level deduplication)? Thanks, Sebastian

[bug?] doveadm -f json who output
by Jasper Spaans 14 Aug '24

14 Aug '24

Hi, I'm trying to parse the output of `doveadm -f json who`[0] and am running into a small issue when it returns data about multiple users: the stream that is emitted in that case is not valid json. dovecot -version tells me dovecot 2.3.21 (47349e2482), more specifically, this is the version shipped in ubuntu 24.04, 1:2.3.21+dfsg1-2ubuntu5 doveadm -f json who [{"username":"<REDACTED>","connections":"4","service":"imap","pids":"(272307 270876 270872 270869)","ips":"(2001:<REDACTED>:7488)"}],{"username":"<REDACTED>","connections":"2","service":"imap","pids":"(271469 271465)","ips":"(2a02:<REDACTED>:9c28)"} When trying to pretty print this with jq, it complains about invalid json: doveadm -f json who|jq [ { "username": "<REDACTED>", "connections": "4", "service": "imap", "pids": "(272307 270876 270872 270869)", "ips": "(2001:<REDACTED>0:7488)" } ] jq: parse error: Expected value before ',' at line 1, column 167 Is this expected behaviour? I would have expected a list of user objects, and then it seems like the list-closing bracket that is currently at the end of the first user object should have been at the end of the last user object. I can code around this in my parser, but would rather not. Best, Jasper [0] actually I'm parsing the output of the doveadm http api, but that just seems to copy the data from the json format in there verbatim

Dovecot refuses to install/run on machine without IPv6
by Kurt Fitzner 14 Aug '24

14 Aug '24

Hi, I just tried to install Dovecot (version 2.3.19.1 9b53102964) on a Debian 12 server I'm building. It failed because Dovecot's default listen address is explicitly "*, ::" and it appears to have no logic to determine if there actually is an IPv6-enabled interface or that IPv6 is enabled on the target machine before it tries to listen on it. If dovecot wants to listen on IPv6 by default, that's neither here nor there, but if this is default behaviour it should check first. I'm curious if it's the same behaviour for machines without IPv4.

CVE-2024-23184: Having a large number of address headers (From, To, Cc, Bcc, etc.) becomes excessively CPU intensive
by Aki Tuomi 14 Aug '24

14 Aug '24

Affected product: Dovecot IMAP Server Internal reference: DOV-6464 Vulnerability type: CWE-770 (Allocation of Resources Without Limits or Throttling) Vulnerable version: 2.2, 2.3 Vulnerable component: lib-mail Report confidence: Confirmed Solution status: Fixed in 2.3.21.1 Researcher credits: Vendor internal discovery Vendor notification: 2024-01-30 CVE reference: CVE-2024-23184 CVSS: 5.0 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:L/A:N) Vulnerability Details: Having a large number of address headers (From, To, Cc, Bcc, etc.) becomes excessively CPU intensive. With 100k header lines CPU usage is already 12 seconds, and in a production environment we observed 500k header lines taking 18 minutes to parse. Since this can be triggered by external actors sending emails to a victim, this is a security issue. The main problem is that each header line's address is added to the end of a linked list. This is done by walking the whole linked list, which becomes more inefficient the more addresses there are. Workaround: One can implement restrictions on address headers on MTA component preceding Dovecot. Fix: Install non-vulnerable version of Dovecot. Patch can be found at https://github.com/dovecot/core/compare/8e4c42d%5E...1481c04.patch

Dovecot CVE-2024-23185: Very large headers can cause resource exhaustion when parsing message
by Aki Tuomi 14 Aug '24

14 Aug '24

Affected product: Dovecot IMAP Server Internal reference: DOV-6601 Vulnerability type: CWE-770 (Allocation of Resources Without Limits or Throttling) Vulnerable version: 2.2, 2.3 Vulnerable component: lib-mail Report confidence: Confirmed Solution status: Fixed in 2.3.21.1 Researcher credits: Vendor internal discovery Vendor notification: 2024-01-31 CVE reference: CVE-2024-23185 CVSS: 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) Vulnerability Details: Very large headers can cause resource exhaustion when parsing message. The message-parser normally reads reasonably sized chunks of the message. However, when it feeds them to message-header-parser, it starts building up "full_value" buffer out of the smaller chunks. The full_value buffer has no size limit, so large headers can cause large memory usage. It doesn't matter whether it's a single long header line, or a single header split into multiple lines. This bug exists in all Dovecot versions. Incoming mails typically have some size limits set by MTA, so even largest possible header size may still fit into Dovecot's vsz_limit. So attackers probably can't DoS a victim user this way. A user could APPEND larger mails though, allowing them to DoS themselves (although maybe cause some memory issues for the backend in general). Workaround: One can implement restrictions on headers on MTA component preceding Dovecot. Fix: Install non-vulnerable version of Dovecot. Patch can be found at https://github.com/dovecot/core/compare/f020e13%5E...ce88c33.patch

Extra listener for client cert ?
by Laura Smith 13 Aug '24

13 Aug '24

Is it possible to, and (if yes) has anyone had experience with setting up an extra listener that requires client certs. The problem I've got is I still need to support Outlook clients. Fortunately these are located in fixed locations on desktop computers. Meanwhile, I would like to harden the configuration for road warriors who are all using devices and OSs that play nicer with client certs than Outlook does (well, Outlook doesn't play at all !). So I was thinking of opening 993 on a seperate IP address with that listener requiring client certificates. The alternative is, of course a VPN, which is still under consideration as an option. But even then, with the security onion, I'd still rather have both .... :)

Synchronize email folders
by Odhiambo Washington 13 Aug '24

13 Aug '24

I moved services to a new server (VPS) when I had issues with my hardware. Now I have copied data from the disk of the old server into the VPS. On the VPS, mail is delivered to /var/spool/virtual/DOMAIN/USER/Maildir/ I have the old emails in /root/DOMAIN/USER/Maildir. What is the easiest way to import the old emails into the current active folders without causing chaos with MuAs?? -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254 7 3200 0004/+254 7 2274 3223 In an Internet failure case, the #1 suspect is a constant: DNS.

Contents of folder symlinked not showing up
by Curt.Blank＠curtronics.com 10 Aug '24

10 Aug '24

I have the directory structure below. I was using uw-imap with Thunderbird. Due to cert issues with Thunderbird which have yet to be resolved at the moment I am using dovecot (2.3-6.11) with Apple's MacOS Mail app. dovecot server is running openSuSE Tumbleweed. With uw-imap & Thunderbird the directory structure and all the mbox's shown below showed up and were accessible in Thunderbird. With dovecot & Apple's MacOS Mail app I see the Archive directory but nothing underneath it. I do not see the In and Out directory nor any of the Year directories. At this point I do not know if the problem lies with dovecot not providing them via IMAP or if Apple's MacOS Mail is just not displaying them. So I am looking for information as to where the problem lies and what the solution is. dovecot -n is included below. /home/<user>/mail/Archive -> /Archive (soft symlink to different mount point) /Archive <directory> | +-> In <directory> | | | +-> 2018 <directory> | | | | | +-> 0118 <mbox> | | +-> 0218 <mbox> | | +-> 0318 <mbox> | | +-> 0418 <mbox> | | +-> 0518 <mbox> | | +-> 0618 <mbox> | | +-> 0718 <mbox> | | +-> 0818 <mbox> | | +-> 0918 <mbox> | | +-> 1018 <mbox> | | +-> 1118 <mbox> | | +-> 1218 <mbox> | | | +-> 2019 <directory> | | | | | +-> 0119 <mbox> | | +-> 0219 <mbox> | | +-> 0319 <mbox> | | +-> 0419 <mbox> | | +-> 0519 <mbox> | | +-> 0619 <mbox> | | +-> 0719 <mbox> | | +-> 0819 <mbox> | | +-> 0919 <mbox> | | +-> 1019 <mbox> | | +-> 1119 <mbox> | | +-> 1219 <mbox> | | | +-> etc. | | | +-> Out <directory> | +-> 2018 <directory> | | | +-> 0118 <mbox> | +-> 0218 <mbox> | +-> 0318 <mbox> | +-> 0418 <mbox> | +-> 0518 <mbox> | +-> 0618 <mbox> | +-> 0718 <mbox> | +-> 0818 <mbox> | +-> 0918 <mbox> | +-> 1018 <mbox> | +-> 1118 <mbox> | +-> 1218 <mbox> | +-> 2019 <directory> | | | +-> 0119 <mbox> | +-> 0219 <mbox> | +-> 0319 <mbox> | +-> 0419 <mbox> | +-> 0519 <mbox> | +-> 0619 <mbox> | +-> 0719 <mbox> | +-> 0819 <mbox> | +-> 0919 <mbox> | +-> 1019 <mbox> | +-> 1119 <mbox> | +-> 1219 <mbox> | +-> etc. | # 2.3.21 (47349e2482): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.21 (f6cd4b8e) # OS: Linux 6.9.7-1-default x86_64 # Hostname: cjbnew.curtronics.com <http://cjbnew.curtronics.com/> mail_location = mbox:~/mail:INBOX=/var/spool/mail/%u managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate mime foreverypart extracttext namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } plugin { sieve = file:~/sieve;active=~/.dovecot.sieve } protocols = imap ssl_cert = </etc/ssl/certs/imapd.crt ssl_cipher_list = ALL:!aNULL:!eNULL:!EXPORT:!DES:!3DES:!MD5:!PSK:!RC4:!ADH:!LOW@STRENGTH ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it ssl_options = no_compression ssl_prefer_server_ciphers = yes userdb { driver = passwd }

Event Export (auth_request_finished)
by Serhii 10 Aug '24

10 Aug '24

I am trying to implement logging of all failed authentication attempts to catch bruteforce automatically. Currently, I have the following configuration: > event_exporter log { > format = json > format_args = time-rfc3339 > transport = log > } > > metric auth_fail { > filter = event=auth_request_finished and not success=yes > exporter = log > } However, in logs I only see events similar to this: > { > "event": "auth_request_finished", > "hostname": "cheems", > "start_time": "2024-08-04T00:00:04.079723Z", > "end_time": "2024-08-04T00:00:12.224906Z", > "categories": [ > "service:auth", > "auth" > ], > "fields": { > "duration": 8145091, > "policy_result": "ok", > "mechanism": "LOGIN", > "transport": "trusted", > "service": "smtp", > "local_ip": "195.201.247.11", > "real_local_ip": "195.201.247.11", > "remote_ip": "185.29.xx.xx", > "real_remote_ip": "185.29.xx.xx", > "original_user": "example(a)example.com", > "user": "example(a)example.com", > "translated_user": "example(a)example.com" > } > } But for me it doesn't look like what is specified in docs[1]: > Field | Description > --- > error | Set when error happens > success | yes, when authentication succeeded > policy_penalty | Time of penalty added by policy server > policy_result | Values: ok, delayed, refused Why I don't see neither "success" and "error" field in logs? Also, why policy_result is ok despite I am logging only failed authentication attempts?

lda not sending email on sieve correctly
by Eduardo Diaz Rodriguez 10 Aug '24

10 Aug '24

Hi to all I was using dovecot like 15 years on multiples debian places, and I have the same issue on debian 12 and debian 11. on my configuration I use exim with 2 process to send email, and at the same time use mailscanner to scan all the email that runs on the server. exim1 get the email, and put on the mailscanner directory and mailscanner scan the email and put on another directory to be send by exim2... Debian-+ 242594 1 0 Jul17 ? 00:00:15 /usr/sbin/exim4 -bd -oY -odq -oX 587:25 -oP /var/run/exim4/exim.pid Debian-+ 242597 1 0 Jul17 ? 00:00:01 /usr/sbin/exim4 -oP /run/exim4/eximqr.pid -q15m -oY -DOUTGOING I enable vacation the users, and works ok, but the issue is related the email sent by dovecot… The mail sent by dovecot lacks of the headers and the SPF and DKMI headers but if I sent the email form my command line using /usr/sbin/sendmail the email has the all the headers…. The mail issue here is with the norms for spam from google the nobody get the vacations emails reply. as far I see on the logs of sendmail I see only the email on the exim4 -DOutgoing (log) (I don't know why) because if I send the mail using send mail go to the whole process I don't know why dovecot send the mail to exim -DOUTGOING and not use sendmail on command line.. There any way to create a warper to capture the mail and sending "like this one" /usr/local/bin/dovecot-sendmail-wrapper I enable the debugn on send mail to see what is doing dovect but no luck Aug 8 02:13:27 servidorabm dovecot: lda(luis.alvarez)<870407><rujXC6cNtGYHSA0A40PlXQ>: Debug: program exec:/usr/sbin/exim: Created Aug 8 02:13:27 servidorabm dovecot: lda(luis.alvarez)<870407><rujXC6cNtGYHSA0A40PlXQ>: Debug: program exec:/usr/sbin/exim: Establishing connection Aug 8 02:13:27 servidorabm dovecot: lda(luis.alvarez)<870407><rujXC6cNtGYHSA0A40PlXQ>: Debug: program exec:/usr/sbin/exim: Forked child process Aug 8 02:13:27 servidorabm dovecot: lda(luis.alvarez)<870407><rujXC6cNtGYHSA0A40PlXQ>: Debug: program exec:/usr/sbin/exim (870409): Connected to program Aug 8 02:13:27 servidorabm dovecot: lda(luis.alvarez)<870407><rujXC6cNtGYHSA0A40PlXQ>: Debug: program exec:/usr/sbin/exim (870409): Finished streaming payload to program Aug 8 02:13:27 servidorabm dovecot: lda(luis.alvarez)<870407><rujXC6cNtGYHSA0A40PlXQ>: Debug: program exec:/usr/sbin/exim (870409): Finished input to program Aug 8 02:13:27 servidorabm dovecot: lda(luis.alvarez)<870407><rujXC6cNtGYHSA0A40PlXQ>: Debug: program exec:/usr/sbin/exim (870409): Disconnected Aug 8 02:13:27 servidorabm dovecot: lda(luis.alvarez)<870407><rujXC6cNtGYHSA0A40PlXQ>: Debug: program exec:/usr/sbin/exim (870409): Waiting for program to finish after 0 msecs (timeout = 30000 msecs) Aug 8 02:13:27 servidorabm dovecot: lda(luis.alvarez)<870407><rujXC6cNtGYHSA0A40PlXQ>: Debug: program exec:/usr/sbin/exim (870409): Child process ended Aug 8 02:13:27 servidorabm dovecot: lda(luis.alvarez)<870407><rujXC6cNtGYHSA0A40PlXQ>: Debug: program exec:/usr/sbin/exim (870409): Destroy Aug 8 02:13:27 servidorabm dovecot: lda(luis.alvarez)<870407><rujXC6cNtGYHSA0A40PlXQ>: sieve: msgid=<2118db23-b529-4b96-8d36-4a9ed7596a03(a)pk25.com>: vacation action: sent vacation response to <ediaz(a)pk25.com> I include a example: This is the mail headers sent using dovecot sendmail ================================================================================================================= X-Spam-Status: No X-Pk25-MailScanner-From: X-Pk25-MailScanner: Found to be clean X-Pk25-MailScanner-ID: 1sbqWj-005lt1-2y X-Pk25-MailScanner-Information: Please contact the ISP for more information Received: from mail-108-mta106.mxroute.com ([136.175.108.106]) by pk25.com with esmtps (TLS1.3) tls TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 (Exim 4.96) id 1sbqWj-005lt1-2y forediaz(a)pk25.com; Thu, 08 Aug 2024 01:57:12 +0200 Received: from filter006.mxroute.com ([136.175.111.3] filter006.mxroute.com) (Authenticated sender: mN4UYu2MZsgR) by mail-108-mta106.mxroute.com (ZoneMTA) with ESMTPSA id 1912f46520a0000a78.001 for<ediaz(a)pk25.com> (version=TLSv1.3 cipher=TLS_AES_256_GCM_SHA384); Wed, 07 Aug 2024 23:57:03 +0000 X-Zone-Loop: a8a214dd47cb92b5b7d264d79136c8507fa7c5926b2e X-Originating-IP: [136.175.111.3] X-Sieve: Pigeonhole Sieve 0.5.13 (cdd19fe3) Message-ID:<dovecot-sieve-1723075020-644445-0(a)servidorabm.interno.abmarquitectos.com> Date: Thu, 08 Aug 2024 01:57:00 +0200 From:<luis.alvarez(a)abmarquitectos.com> To: "Eduardo Diaz Rodriguez"<ediaz(a)pk25.com> In-Reply-To:<071afcb4-79f6-40d6-b12a-e5b23528d951(a)pk25.com> References:<071afcb4-79f6-40d6-b12a-e5b23528d951(a)pk25.com> Auto-Submitted: auto-replied (vacation) Precedence: bulk X-Auto-Response-Suppress: All MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 8bit X-ABM-MailScanner-Information: Please contact the ISP for more information X-ABM-MailScanner-ID: 1sbqWa-003eIu-Kz X-ABM-MailScanner: Found to be clean X-ABM-MailScanner-From: X-Authenticated-Id:smtp@abmarquitectos.com X-SA-Exim-Connect-IP: 136.175.108.106 X-SA-Exim-Mail-From: X-Spam-Checker-Version: SpamAssassin 4.0.0 (2022-12-13) on servidor1.interno.pk25.com X-Spam-Level: X-Spam-Status: No, score=-1.0 required=5.0 tests=BAYES_00,DMARC_NONE, SPF_HELO_NONE autolearn=no autolearn_force=no version=4.0.0 Subject: Respuesta =?utf-8?q?autom=C3=A1tica:?= Vacaciones / Out of office X-SA-Exim-Version: 4.2.1 (built Wed, 06 Jul 2022 17:57:39 +0000) X-SA-Exim-Scanned: Yes (on pk25.com) EstarÃ© de vacaciones del dÃa 5 al dÃa 23 de agosto ambos incluidos con un acceso muy limitado a mi email.

Userdb empty
by Cam Ellison 08 Aug '24

08 Aug '24

I have shifted from a system-based email system to virtual for a website I manage. The MTA is exim4, and user data are in a MySQL database. It will receive email, but with one exception the userdb is empty and emails go out with no username in the email address. Sample error message from exim: 2024-08-05 05:21:43 1sawid-00065N-0R Error while reading message with no usable sender address (R=1sawiX-00065C-1a): at least one malformed recipient address: @scasl.ca - no local part Here is the output of doveconf -n: # 2.3.19.1 (9b53102964): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.19 (4eae2f79) # OS: Linux 6.1.0-20-rt-686-pae i686 Debian 12.6 ext4 # Hostname: football.scasl.ca auth_debug = yes auth_default_realm = scasl.ca auth_mechanisms = plain login auth_username_format = %Ln auth_verbose = yes base_dir = /var/run/dovecot/ hostname = scasl.ca login_trusted_networks = 209.121.143.10/32 mail_debug = yes mail_gid = vmail mail_home = /var/vmail/%n mail_location = maildir:/var/vmail/%n/Maildir:INBOX=/var/vmail/%n/Maildir/INBOX mail_privileged_group = vmail mail_uid = vmail namespace inbox { inbox = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = separator = / } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } postmaster_address = postmaster(a)scasl.ca protocols = " imap" service auth { unix_listener auth-client { mode = 0666 } unix_listener auth-userdb { mode = 0666 } } service imap-login { service_count = 1 } service stats { unix_listener stats-reader { group = vmail mode = 0666 } unix_listener stats-writer { group = vmail mode = 0666 } } ssl_cert = </etc/dovecot/private/dovecot.pem ssl_client_ca_dir = /etc/ssl/certs ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } userdb { driver = passwd } There are two userdb entries, since one of the users is a system user. It is also the only one that appears in userdb. The relevant commands from dovecot-sql.conf.ext are here: password_query = SELECT email_username AS username, domain, email_password AS password FROM league WHERE email_username = '%n' user_query = SELECT CONCAT('/var/vmail/',email_username) AS home, 5000 AS uid, 5000 AS gid FROM league WHERE email_username = '%n' AND domain = '%d' iterate_query = SELECT email_username AS username, domain FROM league The vmail uid:gid is 5000:5000 As a side issue, it cannot open (/proc/self/io) - I'm not sure whether that means anything.

username_filter settings in passdb
by zaxwat93＠gmail.com 06 Aug '24

06 Aug '24

got a problem when configured passdb with username_filter — looks like the option doesn't work OS: FreeBSD 13 and 14. Dovecot version: 2.3.21 Part of config: passdb { args = /usr/local/bin/php /usr/local/dovecot/bin/checkpassword.php driver = checkpassword } passdb { args = /usr/local/bin/php /usr/local/dovecot/bin/checkpassword.php driver = checkpassword username_filter = user1(a)postmaster.local.one default_fields = domain=local.one override_fields = user=postmaster(a)local.one } passdb { args = /usr/local/bin/php /usr/local/dovecot/bin/checkpassword.php driver = checkpassword username_filter = user3(a)user2.local.one default_fields = domain=local.one override_fields = user=user2(a)local.one } When I try command "doveadm auth test user1(a)postmaster.local.one" and enter a password of user1 — it works as planned — change user1(a)postmaster.local.one to user1(a)local.one check it's password and override user to postmaster(a)local.one But when I try "doveadm auth test user3(a)user2.local.one" — it also change user3(a)user2.local.one to user3(a)local.one, and after password check — override it to postmaster(a)local.one Debug logs, when I try "doveadm auth test user3(a)user2.local.one": Aug 1 11:01:03 auth: Debug: Loading modules from directory: /usr/local/lib/dovecot/auth Aug 1 11:01:03 auth: Debug: Module loaded: /usr/local/lib/dovecot/auth/lib20_auth_var_expand_crypt.so Aug 1 11:01:03 auth: Debug: Read auth token secret from /var/run/dovecot/auth-token-secret.dat Aug 1 11:01:03 auth: Debug: passwd-file /usr/local/etc/dovecot.users.list:Read 7 users in 0 secs Aug 1 11:01:03 auth: Debug: auth client connected (pid=0) Aug 1 11:01:03 auth: Debug: client in: AUTH 1 PLAIN service=doveadm debug resp=<hidden> Aug 1 11:01:03 auth: Debug: checkpassword(user3(a)user2.local.one): Performing passdb lookup Aug 1 11:01:03 auth: Debug: checkpassword(user3(a)user2.local.one): execute: /usr/local/bin/php /usr/local/dovecot/bin/checkpassword.php /usr/local/libexec/dovecot/checkpassword-reply Aug 1 11:01:03 auth: Debug: checkpassword(user3(a)user2.local.one): Received input: Aug 1 11:01:03 auth: Debug: checkpassword(user3(a)user2.local.one): exit_status=1 Aug 1 11:01:03 auth: checkpassword(user3(a)user2.local.one): Login failed (status=1) Aug 1 11:01:03 auth: Debug: checkpassword(user3(a)user2.local.one): Finished passdb lookup Aug 1 11:01:03 auth: Debug: checkpassword(user3(a)user2.local.one): Performing passdb lookup Aug 1 11:01:03 auth: Debug: checkpassword(user3(a)user2.local.one): username changed user3(a)user2.local.one -> user3(a)local.one Aug 1 11:01:03 auth: Debug: checkpassword(user3(a)local.one): execute: /usr/local/bin/php /usr/local/dovecot/bin/checkpassword.php /usr/local/libexec/dovecot/checkpassword-reply Aug 1 11:01:03 auth: Debug: checkpassword(user3(a)local.one): Received input: user=user3(a)local.one userdb_home=/var/spool/mail/ userdb_uid=dovecot userdb_gid=dovecot Aug 1 11:01:03 auth: Debug: checkpassword(user3(a)local.one): exit_status=0 Aug 1 11:01:03 auth: Debug: checkpassword(user3(a)local.one): username changed user3(a)local.one -> postmaster(a)local.one Aug 1 11:01:03 auth: Debug: checkpassword(postmaster(a)local.one): Finished passdb lookup Aug 1 11:01:03 auth: Debug: auth(postmaster(a)local.one): Auth request finished Aug 1 11:01:03 auth: Debug: client passdb out: OK 1 user=postmaster(a)local.one original_user=user3(a)user2.local.one I've checked sources and find in " core/src/auth/auth-request.c (from line 617) " code that check username_filter and should send "skipping passdb: username filtered" message in debug, but it doesn't do it. Is it a bug or I've missed something in setup?

Hello, I am running Dovecot 2.3.16 (7e2e900c1a) on RHEL 9.2. I attach my "doveconf -n" configuration. I have replication enabled between 2 servers, both very beefy with 16 cores of Intel(R) Xeon(R) Gold 6244 CPU @ 3.60GHz, 768gb memory, and 100-gig ethernet. The configs are the same except the replication part which points at each other via a puppet template. It seems to work well for most users on modern email clients using the mdbox storage format. The issue I'm having is that some of my users are on the old-style mbox storage format so they can use legacy mail readers such as pine and mutt natively. For some of these users, syncing works just fine. For others, right now about a dozen users, the sync never completes, and I get the following error & backtrace in /var/log/maillog: Aug 4 23:54:22 mail6 dovecot[1177530]: doveadm: Panic: file dsync-mailbox-import.c: line 2163 (dsync_mailbox_import_handle_mail): assertion failed: (array_count(&wanted_uids) > 0) Aug 4 23:54:22 mail6 dovecot[1177530]: doveadm: Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0(backtrace_append+0x46) [0x7fa6ab05c486] -> /usr/lib64/dovecot/libdovecot.so.0(backtrace_get+0x22) [0x7fa6ab05c5a2] -> /usr/lib64/dovecot/libdovecot.so.0(+0x10a41b) [0x7fa6ab06b41b] -> /usr/lib64/dovecot/libdovecot.so.0(+0x10a4b7) [0x7fa6ab06b4b7] -> /usr/lib64/dovecot/libdovecot.so.0(+0x5d11a) [0x7fa6aafbe11a] -> dovecot/doveadm-server(+0x24029) [0x56433f2f7029] -> dovecot/doveadm-server(dsync_mailbox_import_changes_finish+0x29c) [0x56433f32fb9c] -> dovecot/doveadm-server(dsync_brain_sync_mails+0x8d5) [0x56433f331f15] -> dovecot/doveadm-server(+0x52255) [0x56433f325255] -> dovecot/doveadm-server(+0x52639) [0x56433f325639] -> dovecot/doveadm-server(+0x5fa53) [0x56433f332a53] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_call_io+0x6d) [0x7fa6ab081cbd] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0x13a) [0x7fa6ab083bba] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run+0x54) [0x7fa6ab083c64] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_run+0x40) [0x7fa6ab083e20] -> dovecot/doveadm-server(+0x37d7c) [0x56433f30ad7c] -> dovecot/doveadm-server(+0x3974d) [0x56433f30c74d] -> dovecot/doveadm-server(+0x5020b) [0x56433f32320b] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_call_io+0x6d) [0x7fa6ab081cbd] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0x13a) [0x7fa6ab083bba] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run+0x54) [0x7fa6ab083c64] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_run+0x40) [0x7fa6ab083e20] -> /usr/lib64/dovecot/libdovecot.so.0(master_service_run+0x17) [0x7fa6aaff2337] -> dovecot/doveadm-server(main+0x102) [0x56433f2f8f92] -> /lib64/libc.so.6(+0x3feb0) [0x7fa6aac3feb0] -> /lib64/libc.so.6(__libc_start_main+0x80) [0x7fa6aac3ff60] -> dovecot/doveadm-server(_start+0x25) [0x56433f2f9015] Aug 4 23:54:22 mail6 dovecot[1177530]: doveadm: Fatal: master: service(doveadm): child 1117475 killed with signal 6 (core dumped) I'm not sure what might be causing this, and wanted to see if anyone here could offer any suggestions.

Strange ssl/dso troubles on freeBSD13.3

Hi, I'm George and I think I've been running dovecot for like more than a decade now without any troubles, so: WOW! Nevertheless, after an upgrade from FreeBSD 13.2 to 13.3 plus "pkg upgrade" my dovecot installation refuses to load the ssl certificates.

dovecot-lda: timeout for external scripts called by sieve
by Meinhard Schneider 28 Jul '24

28 Jul '24

Hello, I have a small problem with dovecot-lda. I am using Debian 12 Bookworm: root@lnxmail01:~# dovecot --version 2.3.13 (89f716dc2) Historically grown (probably still from sendmail times, long time ago) I always used procmail for local e-mail delivery. This also included the call for spamc for SpamAssassin. I have now changed this and set up a route via sieve. There is a small script for this: root@lnxmail01:~# cat /usr/lib/dovecot/sieve-filter/spamc-filter.sh #!/bin/bash /usr/bin/spamc My sieve configuration says (in extracts): root@lnxmail01:~# head -12 ~meini/.dovecot.sieve ## Generated by Roundcube Webmail SieveRules Plugin ## require ["body","comparator-i;ascii-numeric","copy","envelope","fileinto","imap4flags","include","regex","relational","spamtestplus","vacation","variables","spamtest"]; include :global "spamc"; # rule:[Spam] if spamtest :value "ge" :comparator "i;ascii-numeric" "5" { fileinto "Spam"; stop; } In general, this has been working for many months without any problems. But sometimes the whole thing fails due to a timeout: Jul 7 22:00:13 lnxmail01 dovecot: lda(meini)<766014><G9l7JcPzimY+sAsAmbNf3A>: Error: program exec:/usr/lib/dovecot/sieve-filter/spamc-filter.sh (766016): Execution timed out (> 10000 msecs) Jul 7 22:00:13 lnxmail01 dovecot: lda(meini)<766014><G9l7JcPzimY+sAsAmbNf3A>: Error: program exec:/usr/lib/dovecot/sieve-filter/spamc-filter.sh (766016): Forcibly terminated with signal 15 Jul 7 22:00:13 lnxmail01 dovecot: lda(meini)<766014><G9l7JcPzimY+sAsAmbNf3A>: Panic: output stream (temp iostream in /tmp/dovecot.lda. for (program client seekable output)) is missing error handling Jul 7 22:00:13 lnxmail01 dovecot: lda(meini)<766014><G9l7JcPzimY+sAsAmbNf3A>: Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(backtrace_append+0x42) [0x7ff00aee04e2] -> /usr/lib/dovecot/libdovecot.so.0(backtrace_get+0x1e) [0x7ff00aee05fe] -> /usr/lib/dovecot/libdovecot.so.0(+0xfc49b) [0x7ff00aeec49b] -> /usr/lib/dovecot/libdovecot.so.0(+0xfc501) [0x7ff00aeec501] -> /usr/lib/dovecot/libdovecot.so.0(+0x53aee) [0x7ff00ae43aee] -> /usr/lib/dovecot/libdovecot.so.0(o_stream_unref+0x5e) [0x7ff00af1003e] -> /usr/lib/dovecot/libdovecot.so.0(program_client_destroy+0x8e) [0x7ff00ae6ee6e] -> /usr/lib/dovecot/modules/sieve/lib90_sieve_extprograms_plugin.so(sieve_extprogram_destroy+0x18) [0x7ff00aacd8f8] -> /usr/lib/dovecot/modules/sieve/lib90_sieve_extprograms_plugin.so(+0x556d) [0x7ff00aacb56d] -> /usr/lib/dovecot/libdovecot-sieve.so.0(sieve_interpreter_continue+0xea) [0x7ff00ab4c9ba] -> /usr/lib/dovecot/libdovecot-sieve.so.0(ext_include_execute_include+0x2c7) [0x7ff00ab72e17] -> /usr/lib/dovecot/libdovecot-sieve.so.0(sieve_interpreter_continue+0xea) [0x7ff00ab4c9ba] -> /usr/lib/dovecot/libdovecot-sieve.so.0(sieve_multiscript_run+0x82) [0x7ff00ab62b32] -> /usr/lib/dovecot/modules/lib90_sieve_plugin.so(+0x37a3) [0x7ff00abd47a3] -> /usr/lib/dovecot/libdovecot-lda.so.0(mail_deliver+0x176) [0x7ff00b11f906] -> /usr/lib/dovecot/dovecot-lda(main+0x879) [0x55ef085e4fb9] -> /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xea) [0x7ff00ac3ad0a] -> /usr/lib/dovecot/dovecot-lda(_start+0x2a) [0x55ef085e56ea] The worst thing is that the entire mail is lost (/dev/null)! Then I tried to set the timeout higher (than the current 10 seconds): root@lnxmail01:~# doveconf | grep -A 12 ^plugin plugin { sieve = file:~/sieve;active=~/.dovecot.sieve sieve_execute_exec_timeout = 60s sieve_extension_exec_timeout = 60s sieve_extensions = +vnd.dovecot.filter +spamtest +spamtestplus sieve_filter_bin_dir = /usr/lib/dovecot/sieve-filter sieve_filter_socket_dir = sieve-filter sieve_global = /usr/lib/dovecot/sieve-global sieve_plugins = sieve_extprograms sieve_spamtest_max_value = 5 sieve_spamtest_status_header = X-Spam-Level sieve_spamtest_status_type = strlen } I have set both the values for "sieve_execute_exec_timeout" and "sieve_extension_exec_timeout" to 60 sec, but according to the log, this does not seem to affect the 10000 msec mentioned therein. The SpamAssassin daemon has enough child processes to handle the requests (most of them were idle at the time of the error). How can I configure that the external script gets more time for execution? And what can I do so that - should the script terminate contrary to expectations or be killed in the timeout - the mail is not lost but simply processed further? Many thanks & best regards Meinhard

Looking for Some Help with Dovecot Configuration for IMAP Access
by Selena Thomas 27 Jul '24

27 Jul '24

Hi everyone, I am having a bit of trouble setting up Dovecot for IMAP access. I’ve installed Dovecot and configured the main configuration file,, but I am not sure if I missed something important. Here’s what I have so far ::- 1. Dovecot Version: 2.3.11 2. OS: Ubuntu 20.04 3. Configuration Files: - `/etc/dovecot/dovecot.conf` - `/etc/dovecot/conf.d/10-ssl.conf` - `/etc/dovecot/conf.d/10-auth.conf` I can connect to the server, but I’m having issues with mailbox access and authentication. Does anyone have any tips or common pitfalls I should check: ?? Any guidance would be greatly appreciated..... Thanks in advance...

Sieve duplicate detection not working as expected
by Rosario Esposito 26 Jul '24

26 Jul '24

Hi, On a dovecot server (2.3.21) I have a simple sieve script: require ["duplicate"]; # rule:[duplicate] if duplicate { discard; stop; } I use virtual users with mail aliases on a LDAP backend. I have user "resposit" having 2 mail aliases: - resposit(a)na.infn.it - rosario.esposito(a)na.infn.it If I send a single message to both aliases I still receive 2 copies as you can see from the attached log. Is the "duplicate" sieve extension supposed to work this way ? Any help would be much appreciated ! -- Rosario Esposito

SMTPUTF8 support
by Dāvis Mosāns 26 Jul '24

26 Jul '24

Hi, I'm interested in SMTPUTF8 support in Dovecot. It seems it's still not implemented? Any plans on implementing it? How much work would it be? I couldn't find any mention of this functionality. Postfix has support which is enabled by default but it's not usable if Dovecot doesn't support it. Thanks! Best regards, Dāvis

sieve mail date change
by Marc 24 Jul '24

24 Jul '24

I am a bit rookie with sieve. Some time ago I created a sieve pipe that would sometimes alter alter the subject and move a message to a different mailbox. Currently this results in that a date changes of this message while I don't see anything in the source altering a date. What could be causing this and how to work around this?

Sieve Filters with MySQL
by Adam Miller 24 Jul '24

24 Jul '24

Me again! I am trying to get sieve filters working with a MySQL backend but same to be coming up short. Right now, the error I am getting received is: ------------------------------------------------------------------------------------------------------------------ "User has no active script in storage dict:proxy::sieve;user=username@domain.com" ------------------------------------------------------------------------------------------------------------------ The “username(a)domain.xn--com-9o0a is obviously the email address of the receiving mailbox.

When I run manually queries, everything works fine though I am not entirely sure what the queries are that Dovecot is executing. Any help is appreciated! Also, if I could use the “isActive” field, that would be great as well. My plan to start here is to only have one record in the table per mailbox which would contain all Sieve filters. Eventually, it would be nice if I could adjust the configuration to allow for more than one that returns concatenated so any help there would be great as well! Thank you!

Key metrics to monitor for dovecot at CloudWatch
by Sivakumar Vadivel 24 Jul '24

24 Jul '24

Hello Team, Configured dovecot mail server and SES will receive and forward to SNS topic. Lambda subscribed to the topic and it will receive the mail and write to the EFS volume. EFS volume mounted on both dovecot and lambda. Also enabled AWS Cloudwatch to monitor overall infra. I'm going to enable anomaly detection at Cloudwatch and I want to know the list of key metrics to monitor. I'm thinking of the following metrics. 1. No of bounce 2. PublishFailed & Success 3. EFS disk storage Please suggest the other key metrics, so that I can enable anomaly detection to understand and create the cloudwatch alarm.

Dovecot Stats Plugin
by Adam Miller 23 Jul '24

23 Jul '24

Hello again everyone! I am trying to get the “doveadm stats dump” command to work and even though it does not error, there are no stats. When I try to enable the stats, I get the following error: “Error: Plugin 'stats' not found from directory /usr/lib/dovecot/modules” which is correct, the “stats” plugin does not exist. I do have “/usr/lib/dovecot/stats”.

Dovecot proxy/director/replicator upgrade path
by Andrea Gabellini 23 Jul '24

23 Jul '24

Hello, I manage a Dovecot installation version 2.3.4.1 with a pair of proxy/director in front and two backends that use the replicator plugin to synchronize emails between them. I would like to update all 4 machines and would like to understand if I can directly jump to the latest version 2.3.21 and if there is a logical sequence to follow, such as updating the backends first and then the frontends or vice versa.

Missing IMAP METADATA Plugin

20 Jul '24

OS: Ubuntu 22.04.1 Dovecot: 2.3.16 (7e2e900c1a) When trying to enable the “imap_metadata” plugin, I get the following error: Plugin 'imap_metadata' not found from directory /usr/lib/dovecot/modules I have searched high and low via Google, StackOverflow and even ChatGPT (haha) but I cannot seem to find the package that provides the plugin. Does Dovecot have to be built from source for this plugin to be included? Any help is appreciated. Thank you!

doveadm: SSL handshake failed - wrong version number
by Rachel Roch 19 Jul '24

19 Jul '24

When attempting a doveadm backup, e.g. : doveadm -D backup -Ru user tcp:foo.example.com:12345 I am getting the following error : Error: SSL handshake failed: SSL_accept() failed: error:0A00010B:SSL routines::wrong version number There is nothing wrong with my SSL config because, e.g. openssl s_client -connect localhost:993 works on the source host. So I don't know why doveadm doesn't work. My SSL config is: ssl = required ssl_cert = </etc/ssl/foo.example.com.pem ssl_key = </etc/ssl/foo.example.com.priv ssl_client_ca_dir = /etc/ssl/certs ssl_min_protocol = TLSv1.2 ssl_prefer_server_ciphers = yes ssl_cipher_list = ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:DHE-RSA-CHACHA20-POLY1305 service doveadm { inet_listener { port = 12345 ssl = yes } }

AD authentication with dovecot not working.
by hkhk_exact10 19 Jul '24

19 Jul '24

Hi All, I am trying to setup AD auth with dovecot and have tried a lot of options but still no success. I am using a bind account for AD authentication and the users are not posix accounts. I am not using the ssl cert as its not available, so disabling it. I have used the similar settings with saslauthd+postfix and it worked, not sure what am I doing wrong with configurations..

Any help is appreciated. Thank you!

"panic ... assertion failed" with virtual and flatcurve fts together
by James Cook 17 Jul '24

Hi, I'm getting the following error: $ doveadm fetch 'mailbox storageid' guid '1721115116.M995635P1988.exoco.falsifian.org,S=28763,W=29300' Error: net_connect_unix(/var/dovecot/stats-writer) failed: Permission denied doveadm(falsifian): Panic: file index-search-result.c: line 174 (index_search_result_update_appends): assertion failed: (result->search_args->args == &search_arg) When I remove "virtual" from my "plugins" configuration line and remove the virtual namespace, the search works: $ doveadm fetch 'mailbox storageid' guid '1721115116.M995635P1988.exoco.falsifian.org,S=28763,W=29300' Error: net_connect_unix(/var/dovecot/stats-writer) failed: Permission denied mailbox: Spam storageid: 1721115116.M995635P1988.exoco.falsifian.org,S=28763,W=29300 It also works if I remove fts and fts_flatcurve from my "plugins" configuration line, leaving "virtual" alone. I first saw this when I enabled fts (with fts_flatcurve): I saw a lot of such errors in the logs when I attempted full text searches via neomutt. The errors seemed to stop happening after the indexing jobs finally finished, but just today I saw it again with the above query unrelated to fts. I have been using virtual mailboxes for a long time and hadn't noticed the error before trying fts. $ dovecot --version 2.3.21 (47349e2482) Output of doveconf -n (full config that triggers the error) follows signature. I saw something similar was reported in January [0] (that gave me the idea to try turning off virtual). Please let me know what I can do to help debug. It's just my personal mail server so I might be able to do things like run a debug build if necessary (assuming I find the time).

Debian Bookworm packages, please !
by Laura Smith 16 Jul '24

Debian Bookworm (12) was released June 2023. It is therefore somewhat disappointing to see no Bookworm packages in https://repo.dovecot.org/ce-2.3-latest/debian/

dictionary with %d variable in sql stops insert and select domain part - dovecot 2.3.17+
by Mariusz Piasecki 16 Jul '24

16 Jul '24

Hi, I notice that quota domain when using args %d in dictionary isn't honored in mysql during updates and selects when using dovecot 2.3.17+, so I moved my tests to docker environment, because I started using alpine linux and thought it could be musl library problem. I tested few versions with debian/alpine and after 2.3.17 updates and selects for domain in sql not using domain part, but user@domain. Maybe I missed some changes in configuration, maybe someone experience this behavior? User in logs was changed to h.user(a)example.com. Configuration as described in documentation quota = dict:<quota root name>:<username>[:<option>[...]]:<dictionary URI> where username could be %d for supporting domain-wide quotas quota = dict:user_quota::proxy::sqluserquota quota2 = dict:domain_quota:%d:proxy::sqldomainquota dict { acl = mysql:/etc/dovecot/dovecot-share-folder.conf sqldomainquota =

username_field= domain value_field= bytes } map { pattern= priv/quota/messages table= used_domain_quota username_field= domain value_field= messages } dovecot-dict-sql-user.conf map { pattern= priv/quota/storage table= used_quota username_field= username value_field= bytes } map { pattern= priv/quota/messages table= used_quota username_field= username value_field= messages } Example dump

using dovecot 2.3.17+, so I moved my tests to docker environment, because I started using alpine linux and thought it could be musl library problem. I tested few versions with debian/alpine and after 2.3.17 updates and selects for domain in sql not using domain part, but user@domain. Maybe I missed some changes in configuration, maybe someone experience this behavior? User in logs was changed to h.user(a)example.com. ***** Configuration ***** as described in documentation quota = dict:<quota root name>:<username>[: <option>[...]]:<dictionary URI> where username could be %d for supporting domain-wide quotas quota = dict:user_quota::proxy::sqluserquota quota2 = dict:domain_quota:%d:proxy::sqldomainquota dict { acl = mysql:/etc/dovecot/dovecot-share-folder.conf sqldomainquota = mysql:/etc/dovecot/dovecot-dict-sql-domain.conf sqluserquota = mysql:/etc/dovecot/dovecot-dict-sql-user.conf } dovecot-dict-sql-domain.conf map { pattern = priv/quota/storage table = used_domain_quota username_field = domain value_field = bytes } map { pattern = priv/quota/messages table = used_domain_quota username_field = domain value_field = messages } dovecot-dict-sql-user.conf map { pattern = priv/quota/storage table = used_quota username_field = username value_field = bytes } map { pattern = priv/quota/messages table = used_quota username_field = username value_field = messages } Example dump sql table, in real environment with newer dovecot, there was only h.user(a)example.com and no domain record.

doveadm auth lookup fails for system user

Failed to connect to dns-client: Resource temporarily unavailable
by m＠maltris.org 15 Jul '24

15 Jul '24

When using DNS names for backends in a proxied setup, the async dns_client process after a short time of high load (burst scenario) seems to get overwhelmed: auth: Debug: conn unix:dns-client: dns(backend.local): Lookup failed after 0 msecs: Failed to connect to dns-client: Resource temporarily unavailable auth: Error: DNS lookup for backend.local failed: Failed to connect to dns-client: Resource temporarily unavailable The whole thing itself runs for a few thousand requests until this happens. ulimit nofile is set to 65000. When changing the backend from DNS name to IP, there is no problem. What are the possibilities to use dns names but without these problems? Any way to either increase dns resolving capacity OR cache the results for some time (or forever?)? Best regards

Hello, Does the community version of dovecot have the replication feature? When one dovecot was down, another one could take over the tasks.

These are two distinct plugins. imap-zlib = compression of the IMAP protocol stream zlib = mailbox storage compression on the Dovecot server For 2.4, "zlib" plugin has been renamed to "mail-compress". https://doc.dovecot.org/2.4/core/plugins/mail_compress.html michael

[auth] epoll_ctl(add, 13) failed: Operation not permitted (fd doesn't support epoll)
by Alexander Vogt 05 Jul '24

05 Jul '24

Hi all, dovecot auth service is failing when using an inet_service. The configuration is essentially: service auth { inet_listener { address = * port = 12345 } unix_listener auth-userdb { group = vmail mode = 0666 user = vmail } } When I connect to port 12345 (real IMAP client or telnet doesn't make a difference), the auth service crashes.

dsync will be removed in 2.4 - why?
by Oliver Krone 05 Jul '24

05 Jul '24

Hi there, I recently learned that dsync (mail replication) functionality will be removed in the upcoming releases of dovecot. What is the reason and will there be a replacement? How can I synchronize my e-mails in the future? Thanks a lot. Regards Oliver

Is it possible to access cert_username and original_username the same time?
by bisteycsaba＠gmail.com 05 Jul '24

05 Jul '24

Hello all, If i use auth_ssl_username_from_cert dovecot gets its username from certificate, but seems like it also becomes %orig_user , if i do not use auth_ssl_username_from_cert cert_username completly unaccessable. Is there a way to access the original user supplied username when auth_ssl_username_from_cert is set or am i missed something and there is a variable for cert_username? What i would like to do is use username from cert to determine which email accounts a user with that cert has access to but for that i would both need access to cert_username and the username given by the user, but when username supplied from cert seems like the username supplied by the user no longer accessable, or i cant figure out how to access it. Thanks: Csaba

Doveadm on director
by g.carabella＠panservice.it 04 Jul '24

04 Jul '24

https://doc.dovecot.org/admin_manual/doveadm_mailbox_commands/ As indicated in the documentation above, in case of configuration with the director, the doveadm commands must be executed from the director itself. However, if I try to run the command "doveadm -D mailbox list -u user(a)example.com" the command fails because it tries to lookup user locally instead on one of the backend servers. Where am I wrong? My configuration consists of three directors and three backend servers. Thanks a lot.

One-way synchronization with doveadm/TCP
by Дилян Палаузов 04 Jul '24

04 Jul '24

Hello, the replication procedure described at https://doc.dovecot.org/configuration_manual/replication/ suggests to open a server port 12345 on two systems, and then point each system to the other one. This creates bi-directional synchronization. I want to synchronize only from server A to server B, but not in the opposite direction. Is it sufficient on server A to set service doveadm { inet_listener { port = 12345 } } doveadm_password = secret and server B to set doveadm_port = 12345 doveadm_password = secret ? In other words, when a doveadm client (system B) connects to a server (system A) for replication purposes, does it only read data? Or does it instruct the server also to delete data? To start the replication I had to executed «doveadm replicator replicate '*'». Is in necessary to run this periodically? Thanks for your answer, Дилян

login_access_sockets
by John Fawcett 03 Jul '24

03 Jul '24

Hi I've used Dovecot for a long time but I never stop learning about the depth of features I've never used.... I just discovered the login_access_sockets setting when reading this page: https://doc.dovecot.org/admin_manual/login_processes/ The compilation using --with-libwrap configure setting was not immediate, since on Fedora which I am using there is no tcp_wrappers-devel package so tcpd.h wasn't installed in /usr/include and the library name libwrap.so that was expected by Dovecot needed a symlink to the library installed by tcp_wrappers package. So differently to what I previously understood, Dovecot does have a way of controlling access at connect time via tcp_wrappers hosts.allow and hosts.deny files. But now I also realize that this discovery will be short lived, since I understand this is going away in 3.0 and also 2.4 though I can't find a page on that: https://doc.dovecotpro.com/3.0/installation/upgrading/2.3.x-3.x.html I can understand the logic about slimming down the code to leave out less used features, but this part of the code looks well written and hasn't required much maintenance over the years. I know there's zero chance of reversing the removal of login_access_sockets, but I just wondered whether there could be the chance to introduce a LUA hook at connect time rather than waiting for authentication to be done. Also I have no idea what the overhead of LUA script is, does it spawn additional processes per connection? Thanks John

IMAP login-logout cycle performance with performance mode seems slow/limited and cause cannot be found
by m＠maltris.org 03 Jul '24

03 Jul '24

Hello, I am running a test setup in a docker stack with Dovecot (2.3.21). Basically as a test to see whats possible. The whole thing works okay, but I noticed that with imaptest (latest version) somewhere between 230 and 270 requests per second on a login+logout cycle it cannot go further. However, this is a 384G memory, 48 core, dual-cpu setup that is pretty much idling (utilization somewhere around 6-12%). The ssds are not loaded at all. The memory usage is low. For testing purpose I set nopassword=y and allowed all logins, the users just require a small mysql db lookup which is done once before the cache is filled. If I copy that exact same stack to my local machine, I yield around 450 cycles per second. And the only difference I somehow see is that my local machine has a faster cpu-memory connection and only one cpu with less cores. Is it possible memory speed is a limiting factor because of the cpu-memory-mapping on the server and the slower memory? What performance should I expect? Asking because I am planning to run a stateless client at a later point and the limited login-performance really seems to make that difficult at scale. doveconf -n: # 2.3.21 (47349e2482): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.21 (f6cd4b8e) # OS: Linux 6.8.0-36-generic x86_64 Debian 11.7 ext4 # Hostname: 4e83f0e9d630 auth_cache_negative_ttl = 0 auth_cache_size = 50 M auth_cache_ttl = 5 hours auth_cache_verify_password_with_worker = yes auth_debug = yes auth_debug_passwords = yes auth_failure_delay = 0 auth_mechanisms = plain login auth_verbose = yes auth_verbose_passwords = yes auth_worker_max_count = 500 default_vsz_limit = 2 G disable_plaintext_auth = no doveadm_api_key = # hidden, use -P to show it doveadm_password = # hidden, use -P to show it doveadm_port = 2425 log_debug = event=* log_path = /var/log/dovecot-debug.log login_trusted_networks = 10.0.0.0/8 127.0.0.0/8 mail_debug = yes mail_fsync = never mail_gid = 1000 mail_location = maildir:/data/vmail/%d/%1n/%n mail_uid = 1000 managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate mime foreverypart extracttext namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = nopassword=y driver = static } protocols = " imap lmtp sieve pop3 submission" service anvil { chroot = empty client_limit = 75100 idle_kill = 4294967295 secs process_limit = 1 unix_listener anvil-auth-penalty { mode = 00 } } service auth-worker { client_limit = 1 process_limit = 6000 user = $default_internal_user } service auth { client_limit = 91000 } service doveadm { inet_listener { port = 2425 } inet_listener http { port = 8080 } } service imap-login { process_limit = 15000 process_min_avail = 48 service_count = 0 vsz_limit = 2 G } service imap { client_limit = 1 process_limit = 15000 } userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol doveadm { passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql name = override_fields = port=2425 ssl=no starttls=no } } protocol imap { mail_max_userip_connections = 250 } Best regards

AW: AW: AW: IMAPSieve plugin will not run rspamd script
by postfix_dovecot＠gmx.de 02 Jul '24

02 Jul '24

Hi John, the prefix is just a sign of my desperation - I tried all sorts of variations yesterday and now forgot to undo it. There’s a very detailed tutorial available (German language) with Debian 10. Just the sieve scripts are little different. I spend the time to raise a Debian 10 with this tutorial – and with exact the same result as with my up to date configuration. So it would be interesting for me to know if there is anyone here who has managed to get this to work on Debian? Jens Von: John Fawcett <john(a)voipsupport.it> Gesendet: Montag, 1. Juli 2024 18:26 An: postfix_dovecot(a)gmx.de Betreff: Re: AW: AW: IMAPSieve plugin will not run rspamd script On 01/07/2024 18:08, postfix_dovecot(a)gmx.de <mailto:postfix_dovecot@gmx.de> wrote: Hi John, is there any other log than system? Jens Hi Jens I meant the same type of logging you already posted (i.e. as below) for exactly the same test case, but where the rules use the mailbox name that includes the prefix you set for the namespace (i.e.INBOX/Spam). There is probably a good reason why you have configured a prefix for your namespace, but my suspicion is that the example imapsieve config you copied assumes no prefix set (it was not part of the example so we cannot see it). I personally tried the settings from the example and they work fine and I have no prefix. I also did the opposite test and I get the behaviour you reported when I have prefix set. In order to solve it (without changing the prefix) I had to state the full mailbox name including the prefix in the imapsieve rules. In that case it worked. What I'd like to check in your logging is if there is a clue why it didn't work for you when yu used INBOX/Spam in the rules.

IMAPSieve plugin will not run rspamd script
by postfix_dovecot＠gmx.de 02 Jul '24

Host: VMware Workstation 14.1.8 OS: Debian 12 (Bookworm) Dovecot: 2.3.19.1 Postfix: 3.7.10 Mailclient: Outlook 2016 Hello, I am currently working on a new mail server to replace my Debian 10 mail server. For preparation, I use VMware Workstation to learn and test the installation steps. When I'm eventually done, I'll rebuild my root server from scratch. This time, my problem is getting the IMAPSieve plugin working to trigger rspamd if mail gets moved to the junk folder. Sieve runs well – if rspam recognizes a spam mail, it will be transferred to the junk folder. For me it looks like the IMAPSieve plugin recognizes the move but will not running the script behind. I can see some actions in the log but nothing happens on the rspamd side where the log is also open to view. Moving a mail with Outlook produces the following log entry: imap(mail(a)test.example)<1797><a/FKmgIcqKvAqB4a>: Debug: Module loaded: /usr/lib/dovecot/modules/lib95_imap_sieve_plugin.so imap(mail(a)test.example)<1797><a/FKmgIcqKvAqB4a>: Debug: imapsieve: mailbox INBOX/Spam: APPEND event imap(mail(a)test.example)<1797><a/FKmgIcqKvAqB4a>: Debug: sieve: Pigeonhole version 0.5.19 (4eae2f79) initializing imap(mail(a)test.example)<1797><a/FKmgIcqKvAqB4a>: Debug: sieve: include: sieve_global is not set; it is currently not possible to include `:global' scripts. imap(mail(a)test.example)<1797><a/FKmgIcqKvAqB4a>: Debug: sieve: Sieve imapsieve plugin for Pigeonhole version 0.5.19 (4eae2f79) loaded imap(mail(a)test.example)<1797><a/FKmgIcqKvAqB4a>: Debug: sieve: Sieve Extprograms plugin for Pigeonhole version 0.5.19 (4eae2f79) loaded imap(mail(a)test.example)<1797><a/FKmgIcqKvAqB4a>: Debug: imapsieve: Static mailbox rule [1]: mailbox=`Spam' from=`*' causes=(COPY APPEND) => before=`file:/usr/lib/dovecot/sieve/report-spam.sieve' after=(none) imap(mail(a)test.example)<1797><a/FKmgIcqKvAqB4a>: Debug: imapsieve: Static mailbox rule [2]: mailbox=`*' from=`Spam' causes=(COPY APPEND) => before=`file:/usr/lib/dovecot/sieve/report-ham.sieve' after=(none) imap(mail(a)test.example)<1795><iC6JmQIcnqvAqB4a>: Debug: imapsieve: mailbox INBOX: FLAG event (changed flags: \Deleted) imap(mail(a)test.example)<1795><iC6JmQIcnqvAqB4a>: Debug: sieve: Pigeonhole version 0.5.19 (4eae2f79) initializing imap(mail(a)test.example)<1795><iC6JmQIcnqvAqB4a>: Debug: sieve: include: sieve_global is not set; it is currently not possible to include `:global' scripts. imap(mail(a)test.example)<1795><iC6JmQIcnqvAqB4a>: Debug: sieve: Sieve imapsieve plugin for Pigeonhole version 0.5.19 (4eae2f79) loaded imap(mail(a)test.example)<1795><iC6JmQIcnqvAqB4a>: Debug: sieve: Sieve Extprograms plugin for Pigeonhole version 0.5.19 (4eae2f79) loaded imap(mail(a)test.example)<1795><iC6JmQIcnqvAqB4a>: Debug: imapsieve: Static mailbox rule [1]: mailbox=`Spam' from=`*' causes=(COPY APPEND) => before=`file:/usr/lib/dovecot/sieve/report-spam.sieve' after=(none) imap(mail(a)test.example)<1795><iC6JmQIcnqvAqB4a>: Debug: imapsieve: Static mailbox rule [2]: mailbox=`*' from=`Spam' causes=(COPY APPEND) => before=`file:/usr/lib/dovecot/sieve/report-ham.sieve' after=(none) imap(mail(a)test.example)<1795><iC6JmQIcnqvAqB4a>: Debug: imapsieve: mailbox INBOX: FLAG event (changed flags: \Seen) My /etc/dovecot/local.conf looks like this: ## dovecot.conf # Mailuser im Log mit Namen darstellen verbose_proctitle = yes protocols = imap lmtp sieve ## 10-auth.conf # Disable LOGIN command and all other plaintext authentications unless # SSL/TLS is used (LOGINDISABLED capability).

Oauth2 introspection mode bug(?)
by Scott Q. 01 Jul '24

01 Jul '24

Here goes another oauth2 question, hoping it won't be ignored like all the others. I want to use get/auth on tokeninfo_url but post on introspection_url but dovecot doesn't let me. It doesn't add the auth header on tokeninfo_url whenever introspection_mode == post so, if introspection_mode = post, then dovecot no longer sends auth header to tokeninfo_url . Is this by design, is it a bug ? as can be seen in src/lib-oauth2/oauth2-request.c if (add_auth_bearer && http_client_request_get_origin_url(req->req)->user == NULL && set->introspection_mode == INTROSPECTION_MODE_GET_AUTH) { http_client_request_add_header(req->req, "Authorization", t_strdup_printf("Bearer %s", input->token)); }

Sieve Symlink Error
by Benjamin Rose 01 Jul '24

01 Jul '24

Hello, I'm in the process of moving our mail server from RHEL 6 to RHEL 9. We will be moving to: # dovecot --version 2.3.16 (7e2e900c1a) My issue is that sieve does not appear to work on the new setup, where it does work on the old one. I made a simple filter rule: # cat /u/mail0test/.sieve/ingo.sieve # Sieve Filter # Generated by Ingo (http://www.horde.org/apps/ingo/) (06/28/2024, 11:14:52 PM) require "fileinto"; # Test if header :comparator "i;ascii-casemap" :contains "Subject" "filtertest" { fileinto "Fun"; stop; } Upon sending an email to this test account, the following appears in /var/log/maillog: Jun 29 23:19:56 mail5 dovecot[3066980]: lda(mail0test)<3066980><FA8fFtzOgGZkzC4AuM9lWg>: Warning: sieve: file storage: Active sieve script symlink /u/mail0test/.dovecot.sieve is broken: Invalid/unknown path to storage (points to /u/mail0test/.sieve).

I've set the following directives in /etc/dovecot/conf.d/90-sieve.conf via puppet: augeas { "dovecot_sieve_settings": context => "/files/etc/dovecot/conf.d/90-sieve.conf", changes => [ "set plugin/sieve_dir ~/.sieve", "set plugin/sieve_user_log ~/.sieve/log" ], require => Package["dovecot"], notify => Service["dovecot"]; } The full configuration dump is attached. /u in our environment is the path for user homedirs, which is an NFS mount to a NetApp. The OS is Springdale Linux 9.2, a clone of RedHat from before the IBM license change. It will soon be RHEL 9.4 as we have obtained a license, but for all intents and purposes, Springdale 9.2 and RHEL 9.2 should be considered bug-for-bug compatible. The arch is x86_64 with both machines mail5 and mail6 (replicated) having Intel(R) Xeon(R) Gold 6244 CPU @ 3.60GHz and 768gb of memory. I have the same issue with SELinux in both enforcing and permissive modes, so this is not a permissions error due to SELinux. Am I doing something wrong, or is this a bug? I've seen that there have been some previous issues similar to this that ended up being bugs in pigeonhole, so here I am. Thanks, Ben

Hello all! Is there a quick and easy way to search through an entire mailbox for a user on my dovecot server and glean all the “from” email addresses? This user would like a record of all the email addresses who have contacted him. Thanks in advance for your ideas. Austin Witmer

Anyone knows how to configure Dovecot to send the real remote ip address of the user to the oauth2 provider ( Keycloak in this case ) ? Right now I see the request as coming from the Dovecot server... Thank you, Scott

logging computer name
by hp＠hungpham.no 25 Jun '24

25 Jun '24

I am running Dovecot 2.3.21. One client has multiple computers in their LAN, connecting to my server with a static IP. One or several computers in that LAN keep logging in with failed password, but the Dovecot log only shows the public static IP, like this Jun 25 10:39:20 server-name dovecot[689]: imap-login: Disconnected: Connection closed (auth failed, 2 attempts in 62 secs): user=<xxxx(a)domainyyy.com>, method=PLAIN, rip=client-public-IP, lip=server-IP, TLS, session=<MCLxoK4bksIO8zXR> I tried to enable debug, but there is no more information about the LAN IP or computer names. Is there any setting which helps me with that purpose? So it will be much easier to locate the failed computers in that LAN? Thank you.

Only some of my sent emails are stored in sent-folder
by Nils 21 Jun '24

21 Jun '24

Lots of the emails I send aren't stored in the sent folder. It seems that it mostly (but not always) work for sent emails where the main email-address (the one that is also used as login name) is used as sender. It never seems to work when an alias is used as sender name. There isn't any entry in the mail.err log and nothing that looks suspicious to me in the regular mail.log. I didn't notice it at first, because I usually don't check my sent folder that much, but I it seems to have started when I migrated to the new server a few weeks ago. Any idea what could be the reason for it?

Sieve bug on duplicate extension with MessageID break line
by ricardomachini＠gmail.com 19 Jun '24

19 Jun '24

Hello, I noticed that sieve's duplicate function is not working when the MessageID header has a line break and I have encountered messages originating from Microsoft 365 this way. For example: # test 1 From: <mailto:teste@domain.com.br> teste(a)domain.com.br To: <mailto:cron@domain.com.br> cron(a)domain.com.br Subject: test Message-Id: <mailto:854115.209399851-sendEmail@pa1> 854115.209399851-sendEmail@pa1 Date: Wed, 19 Jun 2024 12:35:16 -0300 (-03) Test # test 2 From: <mailto:teste@domain.com.br> teste(a)domain.com.br To: <mailto:cron@domain.com.br> cron(a)domain.com.br Subject: test Message-ID: <mailto:854115.209399851-sendEmail@pa1> 854115.209399851-sendEmail@pa1 Date: Wed, 19 Jun 2024 12:35:16 -0300 (-03) test # dovecot log Jun 19 12:59:33 server1 dovecot[513090]: lmtp(cron(a)domain.com.br) <mailto:cron@domain.com.br)%3c2993309%3e%3c4AeXHGUAc2adrC0AZCVTkw> <2993309><4AeXHGUAc2adrC0AZCVTkw>: sieve: subject=test from:teste@domain.com.br sender:teste@domain.com.br to: cron(a)domain.com.br <mailto:cron@domain.com.br> size:1010 msgid=854115.209399851-sendEmail@pa1 <mailto:854115.209399851-sendEmail@pa1> status=stored mail into mailbox 'INBOX' delivery_time=3 session_time=1 Jun 19 12:59:35 server1 dovecot[513090]: lmtp(cron(a)domain.com.br) <mailto:cron@domain.com.br)%3c2993309%3e%3csKNOK2cAc2adrC0AZCVTkw> <2993309><sKNOK2cAc2adrC0AZCVTkw>: sieve: subject=test from:teste@domain.com.br sender:teste@domain.com.br to: cron(a)domain.com.br <mailto:cron@domain.com.br> size:1014 msgid=854115.209399851-sendEmail@pa1 <mailto:854115.209399851-sendEmail@pa1> status=stored mail into mailbox 'INBOX' delivery_time=3 session_time=1 # sieve rule require ["duplicate", "fileinto", "envelope", "variables"]; if envelope :matches "from" "*" { set "sender" "${1}"; } if header :matches "subject" "*" { set "subject" "${1}"; } if header :matches "message-id" "*" { if duplicate :seconds 300 :uniqueid "${sender} ${subject} ${0}"{ discard; } } Regards, Ricardo

sieve issue
by savaw82275＠lisoren.com 19 Jun '24

19 Jun '24

Hi! Having a sieve rule: require ["fileinto", "editheader", "variables", "envelope"]; # rule:[med] if allof (address :contains "to" "info(a)mysite.com", header :contains "subject" "invoice") { deleteheader "from"; addheader "from" "info(a)mysite.com"; redirect "final(a)mysite.com"; } I was receiving: redirect action: failed to redirect message to <final(a)mysite.com>: Sendmail program returned error (temporary failure). Enabled debug log level in dovecot, then got some few further lines on this; program exec:/usr/sbin/sendmail (55356): Terminated with non-zero exit code 75 AND this: Error: sieve: redirect action: failed to redirect message to <final(a)mysite.com: Sendmail program returned error (temporary failure). After 2 hours of Google'ing, I finally found a workaround by adding: submission_host = 95.212.12.10 (IP address of my mail server) in dovecot.conf solved the issue. Can someone explain what was the issue and do you guys think this is a correct solution? Regards.

The goal here is when user move messages around imap folders to report them as ham/spam depending on where they originate and where they go. I think Sieve should send copy of the message to Rspamd because otherwise client will see the message dispensary which is not intuitive. Copies are all in the same folder. same message with many hard links placed in the same folder. Mostly happen in Trash and Spam folders. > What are the sizes of these emails? Are they all large?

The memory I'm referring is "vsz_limit=256 MB" and in my opinion it is not the issue but a consequence of the large amount of links in the mail and from there large index file and the result not enough memory to work with. When I delete all the copies the "Out of memory" errors are gone. > But from the sound of it, you have users with many thousands of emails > in a folder or folders.

There are users with large number of mails but only some of them have this issue and some don't.

Sieve generate a lot of hard link copies of mails in mailboxes
by George Asenov 13 Jun '24

13 Jun '24

Hello, I have very strange issue. Sieve generate copies of users messages i.e. not real copies but hardlinks for the same message. It happens to many messages but not every message and not every time, it is not a single user issue I have couple users with that issue. It happens during auto reporting for spam/ham with sieve. But I'm unable to reproduce it. At some point the hardlinks copies become so many that the mailbox index files become so bug that dovecot start throwing error: ################################ dovecot[3385911]: imap(redacted(a)domain.tld)<1992901><RRBL9PQX69IXfCSs>: Error: Mailbox Junk: mmap(size=520636784) failed with file /var/lib/dovecot-virtualmin/index/redacted(a)domain.tld/.Junk/dovecot.index.cache: Cannot allocate memory ################################ other relevant logs are: dovecot: imap-login: Login: user=<redacted.user>, method=PLAIN, rip=YYY.YYY.YYY.YYY, lip=XXX.XXX.XXX.XXX, mpid=3393763, TLS, session=<c1Z1lPsZuPCAWqqI> dovecot: imap(redacted.user)<3393763><c1Z1lPsZuPCAWqqI>: sieve: DEBUG: learn-spam.sieve was triggered on imap.cause=COPY: msgid=<87584056G78841203D85243127W62181551P@idomziqnd> dovecot: imap(redacted.user)<3393763><c1Z1lPsZuPCAWqqI>: sieve: DEBUG: learn-spam on imap.cause=COPY: from=redacted.mail, to=redacted2.mail, subject=Asseyez-vous confortablement, n'importe où..., msgid=<87584056G78841203D85243127W62181551P@idomziqnd>, X-Spamd-Result=default: False [4.49 / 15.00]; FORGED_RECIPIENTS(2.00)[m:redacted2.mail,s:redacted.user.fr]; BAYES_SPAM(1.89)[88.30%]; MID_RHS_NOT_FQDN(0.50)[]; BAD_REP_POLICIES(0.10)[]; RCVD_NO_TLS_LAST(0.10)[]; MIME_GOOD(-0.10)[multipart/related,multipart/alternative,text/plain]; ASN(0.00)[asn:34300, ipnet:62.173.128.0/19, country:RU]; RCVD_COUNT_ONE(0.00)[1]; MIME_TRACE(0.00)[0:+,1:+,2:+,3:~,4:~,5:+]; RCPT_COUNT_ONE(0.00)[1]; MISSING_XM_UA(0.00)[]; ARC_NA(0.00)[]; RCVD_VIA_SMTP_AUTH(0.00)[]; GREYLIST(0.00)[pass,body]; R_DKIM_NA(0.00)[]; FROM_EQ_ENVFROM(0.00)[]; FROM_HAS_DN(0.00)[]; R_SPF_ALLOW(0.00)[+mx]; TO_DN_NONE(0.00)[]; DMARC_NA(0.00)[or.mg]; NEURAL_SPAM(0.00)[0.000] dovecot: imap(redacted.user)<3393763><c1Z1lPsZuPCAWqqI>: sieve: DEBUG: learn-spam send to rspamd spam dovecot: imap(redacted.user)<3393763><c1Z1lPsZuPCAWqqI>: program exec:/var/lib/dovecot/sieve/rspamd-learn-spam.sh (3397238): Terminated with non-zero exit code 1 dovecot: imap(redacted.user)<3393763><c1Z1lPsZuPCAWqqI>: Error: sieve: failed to execute to program `rspamd-learn-spam.sh': refer to server log for more information.

"Read the 'bug reports page' …" -> 404
by H. Thiele 13 Jun '24

13 Jun '24

Hi there, while investigating how to possibly report issues to the Dovecot project I noticed that the link to the "bug reports page" in the "mailing list" section on dovecot.org is broken and leads to a 404. https://www.dovecot.org/mailing-lists/ -> "Read the 'bug reports page' before posting a bug report. …" -> "The page you are looking for is not found" regards, H. Thiele

I also noticed this affects local documentation in the Dovecot release (v2.3.21), e.g. the old URL is referenced in many of the man files that get installed. It is probably a good idea to setup a 301 redirect rather than just dumping a 404 on the website too. On 12/06/24 8:05 AM, aki.tuomi wrote: > Thanks for letting us know.

how to disable port 143
by Jeff Peng 10 Jun '24

10 Jun '24

Hello, I have commented out this line in 10-master.conf: service imap-login { inet_listener imap { #port = 143 } But this doesn't close the port 143. So I have changed it to: service imap-login { inet_listener imap { address = 127.0.0.1 port = 143 } This let port 143 listen on local address. my question, is it possible to close port 143 entirely in dovecot? Thanks.

Lots of "Corrupted dbox file" errors in log
by simon＠simonliebold.de 10 Jun '24

10 Jun '24

Hi, I'm leaving this here for others who may see the same issue and are equally perplexed as I was: Dovecot version 2.3.16 w/ sdbox mailbox format. Yesterday, I noticed that I did not see any new mail in Thunderbird. But for whatever reason, new mail did show up on my phone with K9 mail. So, new mails were retained. In the Dovecot logs, I was seeing multiple errors: Corrupted dbox file read() failed for file No buffer space available EOF while reading file header Mailbox INBOX: sdbox: Rebuilding failed Mailbox INBOX: Deleting corrupted cache: reset_id mismatch even after locking The "Corrupted dbox file" and "EOF while reading file header" error was caused by a message file in the INBOX mailbox that was 6681 bytes in size and had all NUL characters. File date of that file was more than two years ago. The "No buffer space available" error was caused by a file that also had a lot of NUL, but also a few other characters in it. Nothing resembling regular message files with headers and body. In total it was a handful of files causing issues. I deleted them all with: doveadm expunge -u {user} MAILBOX INBOX UID {filename without the leading 'u.'} Afterwards Thunderbird showed new mails again. I did not need to restart it. No more errors in the Dovecot logs. Not sure what had caused this. Maybe somebody has seen this before. Simon

[Patch] Allow sieve redirects to specified domains only
by Kadlecsik József 10 Jun '24

10 Jun '24

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.

[Patch] blocklist access control for dovecot pop3/imap and pigeonhole managesieve
by John Fawcett 09 Jun '24

09 Jun '24

Hi Just in case this is useful more generally, I'm posting it to the list. While Dovecot has an access control via allow_nets, it is a user database field that applies only at the authentication stage to deny access for the specific user when there is a connection attempt from an unauthorized ip for that user. https://doc.dovecot.org/configuration_manual/authentication/allow_nets/ I don't believe there is anything that checks access at connect time to deny unwanted traffic prior to authentication, for example from compromised machines, botnets etc. Though failed connection attempts do not appear to be a significant issue, maybe better to add some safety net for the future. The attached patch is proof of concept code that introduces the parameters rbl_check and rbl_check_timeout (msecs) to the protocol section. Tested for imap, pop3 and sieve. The following is an example for sieve. protocol sieve { rbl_check = zen.spamhaus.net=127.0.0.4 rbl_check_timeout = 5000 } If the lookup results in a hit the client is disconnected with a BYE "Disconnected for policy." message and the logs report: Jun 09 12:00:56 server.example.com dovecot[977650]: managesieve-login: Disconnected: Policy (disconnected before auth was ready, waited 1 secs): user=<>, service=sieve, rip=n.n.n.n, lip=n.n.n.n The patch also makes the number of pre-login errors and post-login errors configurable (max_login_command_errors and max_command_errors respectively) for pop3, imap and sieve protocols . protocol sieve { max_command_errors = 1 max_login_command_errors = 1 } A potential extension to the logic would be "allow_nets" and "disallow_nets" parameters or maybe something more sophisticated to allow ips/networks that would otherwise be blocked or deny additional ips/networks.

Error: Mailbox Spam: Failed to autocreate mailbox: Mailbox can't be created
by Jordan Rosenthal 09 Jun '24

09 Jun '24

Hi, I am getting the error "Error: Mailbox Spam: Failed to autocreate mailbox: Mailbox can't be created" and cannot figure out what is causing it. It seems like some sort of permissions issue, but nothing I have tried seems to fix the problem. I was running my setup for many years without issue, and this error started occurring after a recent Ubuntu upgrade. I am using getmail 6.18.4 to fetch mail from a mail server, which then calls /usr/lib/dovecot/deliver to deliver the mail to my local system. It is during this delivery that the error occurs. The dovecot-lda executable exits with status 75 and the log file contains: Jun 09 08:05:54 honeydukes dovecot[1863]: lda(sally)<1863><L9pgDaKaZWZHBwAASkLcPA>: Error: Mailbox Spam: Failed to autocreate mailbox: Mailbox can't be created Jun 09 08:05:54 honeydukes dovecot[1863]: lda(sally)<1863><L9pgDaKaZWZHBwAASkLcPA>: msgid=<REDACTED>: save failed to open mailbox Spam: Mailbox Below is my dovecot configuration.

Accessing IMAP from Python with Encrypted Password
by adam＠ardaemail.com 09 Jun '24

09 Jun '24

Hello again Dovecoters! I have a need to access an IMAP mailbox via a Python script to parse and stored DMARC reports in a SQL database. Right now, I have it working however I am storing the password in plaintext in my database which obviously is not secure. How would you approach this scenario? Would you store the password in the database encrypted and configure Dovecot to accept said encrypted password? If so, can you point me in the right direction to configure Dovecot to handle this? If not, what would you recommend? Is it possible to intercept the email and upload the attachments to an AWS S3 bucket then move the email to another folder? Likewise, if someone wants to help here as well, I need to send outbound email via an authenticated user from Postfix. How would you approach this scenario? Thank you!
