Example configs and packaging scripts
by Aki Tuomi 28 Jan '25

28 Jan '25

Hi! To make the transition from 2.3 to 2.4 easier, especially for package maintainers, we have prepared one-time conversion of 2.3 example configurations to 2.4. Please find them at https://github.com/dovecot/tools/blob/main/dovecot-2.4.0-example-config.tar… Please review release notes and changelogs for needed changes in future releases. Also, would like to remind that https://repo.dovecot.org/ce-2.4-latest/debian/bookworm/pool/main/ contains the debian.tar.xz used to build our packages, and similarly for rhel based https://repo.dovecot.org/ce-2.4-latest/rhel/9/SRPMS/ has the source RPMs. Kind regards, Aki Tuomi

dovecot: master: Warning: service(imap-login): process_limit (100) reached, client connections are being dropped

Hello, I would need a little help. I have the following message in the logs dovecot: master: Warning: service(imap-login): process_limit (100) reached, client connections are being dropped I have already modified the file /etc/dovecot/conf.d/10-master.conf The first 2 lines are default_process_limit = 200 default_client_limit = 1250 and if i make: grep -r process_limit /etc/ he found that: /etc/dovecot/conf.d/10-master.conf:default_process_limit = 200 /etc/dovecot/conf.d/10-master.conf: process_limit = 1024 /etc/dovecot/conf.d/10-master.conf: #process_limit = 1024 /etc/dovecot/conf.d/10-master.conf: process_limit = 1024 /etc/dovecot/conf.d/10-master.conf.original:default_process_limit = 150 /etc/dovecot/conf.d/10-master.conf.original: #process_limit = 1024 /etc/dovecot/conf.d/10-master.conf.original: #process_limit = 1024 /etc/dovecot/conf.d/10-master.conf.original: #process_limit = 1024 /etc/dovecot/conf.d/20-managesieve.conf: #process_limit = 1024 And so I don’t really understand why this error message remains at 100, I specify that the postfix and dovecot services were restarted after the modification,

Tests failed in 2.4.0 (Possibly time-zone-related?)
by Peter 27 Jan '25

27 Jan '25

I'm getting the following failed test: test-var-expand.c:464: Assert failed: labs(t0 - t1) < 10 3600 < 10 is not true var_expand(providers) ................................................ : FAILED This test appears to be a timestamp comparison as per this comment: /* Ensure the time is within 10 seconds */ being exactly one hour off makes me suspect a time-zone issue on the build machine. This machine is in NZDT which is currently in daylight savings time which makes me suspect that this is an issue that is specific to dovecot being built in a timezone in the southern hemisphere. Shouldn't the comparison be done on UTC time instead of localtime to avoid these issues? Peter

Errors using dovecot 2.4 container image
by Andreas Achtzehn 26 Jan '25

26 Jan '25

Dear Dovecot team, I ran into troubles using the newly released 2.4 docker image. The dovecot/dovenull users are apparently not part of the image -- hence the dovecot server fails to start up with a fatal error. I'm using a vanilla configuration, default_login_user, etc. are not set. Thanks for having a look! Best regards, Andreas

Latest docker image broken
by Stephen Benjamin 26 Jan '25

26 Jan '25

I use watchtower to keep my docker images up to date and the image pushed to latest tag yesterday broke everything - I can’t find any docs saying anything about mail_location being removed or replaced…. Any idea? I’m unfortunately away from my laptop for a few days so I can’t do any deep debugging but I’d appreciate any pointer. doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf line 1: mail_location: Unknown setting: mail_location Sent from my iPhone

Help with migration of Quota config to 2.4.0?
by dovecot.org＠schildbach.de 25 Jan '25

25 Jan '25

I've converted most of my config to 2.4.0, but one thing I don't get from the docs: ``` mail_plugins = $mail_plugins quota protocol imap { mail_plugins = $mail_plugins imap_quota } plugin { quota = maildir:User quota:noenforcing quota_rule = *:storage=7GB quota_rule2 = Trash:storage=+10%% } ``` How would this translate?

Dovecot 2.4.0 compilation issues (Linux, GCC 8.3.1)
by Andreas M. Kirchwitz 25 Jan '25

25 Jan '25

Hello users of Dovecot! Currently, Dovecot 2.3.21.1 compiles and runs fine on a Red Hat Linux clone with GCC 8.3.1. Now tried the brandnew sources of Dovecot 2.4.0, but to my surprise it doesn't even compile and I have no clue where to begin my debugging. Besides some minor things (new OpenSSL version check not working, maybe because not using proper include files; and one library is missing -lrt to use clock_gettime), I'm totally stuck at compiling the new "src/lib-http/http-server-settings.c". It fails while including "src/lib/macros.h" with the message "error: size of unnamed array is negative" Dovecot 2.3.21.1 has no http-server-settings.c but a very similar macros.h which everbody seems to be happy about. So what is it that happens while compiling http-server-settings.c to make GCC fail? I ran "./configure" with just LDFLAGS="-lrt -Wl,--no-as-needed" added, and then simply "make". Nothing special here. I'm happy with all the default settings and auto-detected options. Full log of compilation messages is appended at the end of this message. Any help is highly appreciated. Currently I have no idea where to even start my search for a workaround or even a solution. Never had such problems with compiling Dovecot so far. Thanks a lot in advance ...

newbie dsync problems
by Kent Borg 25 Jan '25

25 Jan '25

I have a very basic postfix/dovecot server, with just a few users, and it works. But in the past I have had hardware failures…so I would like use dsync to a nearly matching server for some extra safety, and I have not yet been successful. I am trying to do this as root over ssh, with a private key for authentication. I do not managed to get the whole replicator thing working, so as part of simplifying things I am trying to run dsync manually, just on one user (myself). I hope this isn't a silly approach. What would the manual command look like? The closest example on the man page is: > $ doveadm sync -u username(a)example.com ssh -i id_dsa.dovecot \ > mailuser(a)example.com doveadm dsync-server -u username(a)example.com I try to change that to match my case and it has never heard of me: > root@la:/etc/dovecot# doveadm sync -1 -u kentborg(a)mail.borg.org ssh -i > /root/.ssh/id_rsa_rc.borg.org.dsync kentborg(a)mail.borg.org doveadm > dsync-server -u kentborg(a)mail.borg.org > doveadm(kentborg(a)mail.borg.org): Error: User doesn't exist > root@la:/etc/dovecot# I drop the machine part of the name and it knows who I am on this end but can't get to the other end: > root@la:/etc/dovecot# doveadm sync -1 -u kentborg ssh -i > /root/.ssh/id_rsa_rc.borg.org.dsync kentborg(a)mail.borg.org doveadm > dsync-server -u kent\ > borg(a)mail.borg.org > kentborg(a)mail.borg.org's password: I think I have root's ssh keys set up correctly, I can run this: > root@la:/etc/dovecot# ssh -i /root/.ssh/id_rsa_rc.borg.org.dsync > mail.borg.org > PTY allocation request failed on channel 0 > C-c C-croot@la:/etc/dovecot# …and on the remote end I see some debugging output I put in the remote script, outputting an empty username. Makes sense. If I try to put that in this (incomplete) dsync command: > root@la:/etc/dovecot# doveadm sync -u kentborg -1 ssh -i > /root/.ssh/id_rsa_rc.borg.org.dsync mail.borg.org > Error: Extraneous arguments found: 3 5 > doveadm(kentborg)<1029674><QvOnDPmKkmcqtg8AA8+vgQ>: Error: > read(remote) failed: EOF (version not received) > doveadm(kentborg)<1029674><QvOnDPmKkmcqtg8AA8+vgQ>: Error: Remote > command returned error 64: ssh -i /root/.ssh/id_rsa_rc.borg.org.dsync > mail.borg\ > .org dsync-server > root@la:/etc/dovecot# And the remote end outputs the username as "VERSION dsync 3 5", okay, maybe progress. But when I try to make the command more complete and send a username to the remote end, and now I am no longer talking to the remote end: > root@la:/etc/dovecot# doveadm sync -u kentborg -1 ssh -i > /root/.ssh/id_rsa_rc.borg.org.dsync remoteprefix(a)mail.borg.org > remoteprefix(a)mail.borg.org's password: Suggestions? Thanks, -kb

TLS Connections Between Dovecot & MariaDB
by duluxoz 25 Jan '25

25 Jan '25

Hi All, I'm using a MariaDB backend to a Dovecot server, with TLS required by the MariaDB server for connections. My sql_dovecot.conf.ext file is using the following connection line: `connect = host=mariadb.example.com dbname=mail_server user=vmail password={REDACTED} ssl_ca=/etc/pki/tls/certs/root_ca.crt`. I can't work out from the doco or Google what else I need in that line, but I suspect it'll be something like: `ssl_cert=/etc/pki/tls/certs/vmail_rsa.pem ssl_key=/etc/pki/tls/certs/vmail_rsa.key`. Could someone please confirm this and let me know the actual extra commands/options - thanks Cheers Dulux-Oz

Virtual folders in top level hierarchy
by Robert Sanchez 25 Jan '25

25 Jan '25

Hi, I've got a virtual "Flagged" folder but it appears as a subfolder of "virtual" instead of being alongside Inbox, Sent, etc. I've seen some previous messages where this was asked, but they didn't really seem to achieve what I want. My expectation was that calling the defined "virtual.Flagged" folder in the inbox namespace would link it there, but either that is not the expected behavior or I'm doing something wrong. This is my current config: namespace virtual { location = virtual:/etc/dovecot/virtual:INDEX=~/virtual:CONTROL=~/virtual:VOLATILEDIR=~/virtual/ prefix = virtual. separator = . list = yes hidden = no } namespace inbox { # (...) default Drafts, Junk, etc. # If you have a virtual "Flagged" mailbox: mailbox virtual.Flagged { special_use = \Flagged auto = subscribe comment = All my flagged messages } } I've also tried "hidden = yes" and "list = no", but I don't see any differences in the client. This is Dovecot 2.3.21 (47349e2482) on Ubuntu 24.04, btw. Thanks.

Proper syntax for using `allow_nets` with dovecot passdb sql

Hi there, I posted this question in ServerFault (https://serverfault.com/questions/1170095/proper-syntax-for-using-allow-net…) but haven't gotten an answer after 10 days so thought I'd try here, I appreciate any help you can offer! I want to allow for two auth methods in dovecot via SQL. First, the traditional route where the password is hashed with |SHA512-CRYPT| and compared to the DB response. Second, where the request is coming from a user already authenticated by a different part of the local system, and the hash itself is passed and compared as |PLAIN|. It works perfectly with the following |auth-sql.conf.ext| and associated sql files... |# Passdb for traditional method passdb { driver = sql args = /etc/dovecot/conf.d/dovecot-sql.conf.ext } # Passdb for hybrid method (direct hash comparison) passdb { driver = sql args = /etc/dovecot/conf.d/dovecot-sql-hybrid.conf.ext } # Userdb prefetch to use attributes from the passdb query userdb { driver = prefetch } # Userdb static as fallback for default attributes userdb { driver = static args = uid=vmail gid=vmail home=/srv/mail/%d/%n } | The problem I'm having is that I want to secure the second hybrid |PLAIN| method so that it can only be used by the local host using the |allow_nets| argument. In the documentation <https://doc.dovecot.org/2.3/configuration_manual/authentication/allow_nets/…> it shows that I should simply add it to the |args| like this... |args = /etc/dovecot/conf.d/dovecot-sql-hybrid.conf.ext allow_nets=local,127.0.0.1/32 | But as soon as I do this, the logs show that it's trying to open the entire string as if the |allow_nets...| argument is part of the path, and fails to find the file. I've tried moving the |allow_nets| argument to the beginning, but that had the same result. What is the correct syntax for using |allow_nets| with |passdb sql|? # 2.3.16 (7e2e900c1a): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.16 (09c29328) # OS: Linux 5.14.0-503.21.1.el9_5.x86_64 x86_64 Rocky Linux release 9.5 (Blue Onyx) xfs Thanks, Kevin.

Hi Robert, I corrected the service imap-login section of both dovecot.conf AND conf.d/10-master.conf as you suggested, The files in ssl_cert and ssl_key exist and are readable by dovecot. I have even changed for testing the permission of /etc/letsencrypt/live /etc/letsencrypt/archive to 0755 and restarted dovecot. However, the output of ss -tuln | grep 993 is still null. What next? Thanks ---------- Forwarded message --------- Da: Robert Nowotny <rnowotny(a)rotek.at> Date: mar 21 gen 2025 alle ore 23:47 Subject: RE: Fwd: [OFFLIST] Re: connection refused, no error anywhere To: Marco Fioretti <marco.fioretti(a)gmail.com> To resolve the connection refused error when accessing Dovecot on the new server, you need to adjust the Dovecot configuration to enable the appropriate IMAP service ports. 1. Enable IMAPS (Port 993) for Secure Connections: - Modify the `service imap-login` section in your Dovecot configuration (likely in `/etc/dovecot/conf.d/10-master.conf`) to include an `imaps` listener: ```conf service imap-login { inet_listener imap { port = 0 # Disables plain IMAP (port 143) } inet_listener imaps { port = 993 ssl = yes } } ``` - This configuration disables plaintext IMAP on port 143 and enables IMAPS on port 993 with SSL. 2. Ensure SSL Certificates Are Correct: - Verify the paths to your SSL certificate and key in `/etc/dovecot/conf.d/10-ssl.conf`: ```conf ssl_cert = </etc/letsencrypt/live/example.com/fullchain.pem ssl_key = </etc/letsencrypt/live/example.com/privkey.pem ``` - Confirm the files exist and have proper permissions (readable by Dovecot). 3. Restart Dovecot: ```bash sudo systemctl restart dovecot ``` 4. Verify Dovecot is Listening: ```bash sudo ss -tuln | grep 993 ``` - You should see Dovecot listening on port 993. 5. Test the Connection Using SSL: ```bash openssl s_client -connect example.com:993 ``` - This should establish a secure connection to the IMAPS port. Additional Recommendations: - Disable Plaintext IMAP: Keeping `port = 0` for the `imap` listener ensures unencrypted IMAP is disabled, enhancing security. - Firewall Configuration: Confirm UFW allows port 993: ```bash sudo ufw allow 993/tcp ``` By enabling IMAPS on port 993 and ensuring SSL is properly configured, secure email access will be restored. If you must use port 143 (not recommended), set `port = 143` in the `imap` listener and enforce STARTTLS by adding `ssl = required` in your SSL configuration. *Von:* Marco Fioretti via dovecot <dovecot(a)dovecot.org> <dovecot(a)dovecot.org> *Gesendet:* Dienstag, 21.

dovecot not listening, but doing passw checks? Was: connection refused, no error anywhere
by Marco Fioretti 22 Jan '25

22 Jan '25

Greetings, I just woke up and went back to try to diagnose the problem I first reported in my other thread, and noticed something weird. After your suggestions, the situation is as follow: 0) FTR, postfix is working, if I open the local mailboxes with mutt running on the server I do see email coming in as expected, from mailing lists and our correspondents 1) output of dovecot -n is below 2) both "ss -tuln | grep 993" and "netstat -tanp" show NO activity /presence on port 993 3) BUT, running "service dovecot status" (see output below, I only changed server and user name) I noticed a failed authentication attempt from SOMEUSER2, happened ~15/20 minutes before I checked, where "SOMEUSER" (without the trailing "2") is an ACTUAL user of the old server, and 200.89.159.59 an IP address I don't know (not my desktop's for sure, and AFAIK no legitimate user is trying to use the server at this time, they know I'm rebuilding it...) Now the question is, OK, that attempt may be some attacker trying to get in, this happens but... HOW is he succeeding to TRY to connect, if dovecot doesn't appear to be listening at all??? And of course, does this help in any way to figure out what is wrong with my configuration?

Greetings, I was just tasked with rebuilding from scratch the mail server of an NGO, on a brand new Ubuntu 24.04 LTS VPS.

Mail with single \r, partial fetch, error "Broken virtual size in mailbox"
by Ewald Dieterich 17 Jan '25

17 Jan '25

I run Dovecot 2.3.21 with the mdbox mailbox format. If I do a certain partial fetch on a mail with a single carriage return \r Dovecot closes the connection and logs the following error: Error: Mailbox INBOX: Deleting corrupted cache record uid=1: UID 1: Broken virtual size in mailbox INBOX: read(/var/spool/dovecot/user/storage/m.1): FETCH BODY[]<18.100> got too little data: 5 vs 6 This happens every time, doveadm force-resync doesn't help. Here's how to reproduce the issue: Deliver a mail with a single carriage return \r (here after the header/body separator, but that's not important): echo -ne "Subject: Test\r\n\r\n\rBody\r\n" | doveadm save -u user Then do a partial fetch from a specific offset: . fetch 1 body[]<18.100> * 1 FETCH (BODY[]<18> {6} ody Connection closed by foreign host. Offset 18 with length 6 should "Body\r\n", that's why the response is 1 byte short ("got too little data: 5 vs 6" in the error message), by why is \r causing this? Other offsets seem to work.

Bug report on attachment search in dovecot fts plugin
by h.murakami＠lab8.co.jp 10 Jan '25

10 Jan '25

Hi. I am using dovecot's fts plugin and have found a bug-like behavior. I have confirmed that dovecot by itself with fts plugin disabled works fine. dovecot --version 2.3.19.1 (9b53102964) The pattern we found is as follows 1. search with `with attachments` condition from RoundCube linked to dovecot 2. dovecot fts plugin executes the following query to solr but no document is found hdr:application%5c%2f+OR+hdr:multipart%5c%2fm+OR+hdr:multipart%5c%2fsigned+OR+hdr:multipart%5c%2freport 3. roundcube search results also show no items found That's all I have to report. If there is any way to improve the situation, we would like to receive it.

repo.dovecot.org status
by Jasper Spaans 06 Jan '25

06 Jan '25

Hello list, We're using the packages from repo.dovecot.org to run the latest version of dovecot on our systems running ubuntu focal (20.04). We'd like to upgrade these to a more recent ubuntu version[1], but those builds are not available on repo.dovecot.org. Is that repo still supported? If so, what would it take to get builds for ubuntu 22.04 and/or 24.04 on there? I can spend some time on that, but I also have the impression that the build infra (including the scripts) that generate the packages for this repo is not very public. Cheers, Jasper [1] for reasons that are out of scope for this message, using a dockerized build or upgrading to 24.04 (which does come with 2.3.21) is not an option at this moment, so we are currently looking at 22.04. unfortunately that also comes with a dovecot from 2022

SCRAM-SHA -PLUS variants and Dovecot (Channel Binding)
by * Neustradamus * 04 Jan '25

Dear all, In first, I wish you a Happy New Year 2025! In the past, I have requested SCRAM support in Dovecot, etc. I would like to know the situation with -PLUS variants (Channel Binding)? This feature for more security is always missing. RFC 9266: Channel Bindings for TLS 1.3: - https://datatracker.ietf.org/doc/html/rfc9266 Little details, to know easily: - tls-unique for TLS =< 1.2 - tls-server-end-point - tls-exporter for TLS = 1.3 Can you add tls-unique, tls-server-end-point and tls-exporter to be perfect? Stephan Bosch has started but no news since one year: - https://github.com/dovecot/core/compare/main...stephanbosch:dovecot-core:sa… Other links: SASL2 I-D: Extensible Simple Authentication and Security Layer (SASL): - https://datatracker.ietf.org/doc/html/draft-melnikov-sasl2 It is in several XEPs too: - XEP-0388: Extensible SASL Profile: https://xmpp.org/extensions/xep-0388.html - XEP-0440: SASL Channel-Binding Type Capability: https://xmpp.org/extensions/xep-0440.html - XEP-0474: SASL SCRAM Downgrade Protection: https://xmpp.org/extensions/xep-0474.html - XEP-0480: SASL Upgrade Tasks: https://xmpp.org/extensions/xep-0480.html Thanks in advance.

Hello, After upgrading Dovecot from version 2.3.4 to 2.3.19 i noticed errors for some users having sieve redirects. Before upgrade all worked fine. In sieve plugin i have two limits: sieve_max_actions = 500 sieve_max_redirects = 150 If user have up to 100 redirects all works fine but if there are 101 or more none of them works and there is error: dovecot: lmtp(test2.mbox) Error: sieve: msgid=<***l>: redirect action: failed to check for duplicate forward to <101th.email.address> It seams that there is another limit but cant find where. When checked "dovecot -n|grep 100" there was only "default_process_limit". Increasing this changed nothing. Still the same error. File ".dovecot.sieve.log" in user home dir don't have any additional information. There is only: redirect action: failed to check for duplicate forward: internal error occurred: refer to server log for more information. Do you have any ideas how to fix it? -- Best regards, Maciej Polewczyński Do or do not. There is no try.

Moving all mail from one user to another
by Peter Reinhold 29 Dec '24

29 Dec '24

Hi all I have a user that has changed domain, and I am looking to move all her mail from her old account into her new one, but I am really unsure about how to go about it I would think that I am should use https://doc.dovecot.org/main/core/man/doveadm-move.1.html to do it, but the example supplied and all discussion about that tool I can find online is only about moving a users mail across folders on their account, and not the entire accounts content to another account. Has anyone tried to do something like this? -- Peter Reinhold

vacation auto reply mail line endings CR LF
by tobias.niethammer＠projektb.net 21 Dec '24

21 Dec '24

Hi all, I tried to setup dovecot 2.3.21.1 (d492236fa0) (dovecot-pigeonhole-0.5.21.1) with the sieve vacation function. I'm getting here a bit into trouble. if I sent an e-mail to an receipient dovecot does via dma and the local mailserver an mail reply but the mail does only have the header inside. After a bit research my conclusion is that the reply mail which gets generated has line endings CR LF. I have to remove this manualy and set it to \LF to get the mail correcly transfered. I Setup the sieve rule with roundcube. I tried to manualy change the .dovecot.sieve file endings and comipled with sievec .dovecot.sieve .dovecot.svbin the binary again, with no change in the behavior. I guess i missed somewhere an variable to fix this issue? here the sieve file: #################################################### require ["vacation"];^M # rule:[Urlaub]^M if true^M {^M vacation :addresses "test02(a)projektb-mail.net" :subject "test Urlaub" text:^M test 1 test 2 test 3^M .^M ;^M }^M #################################################### thank you for your Support Tobias

ACL propagation with acl_defaults_from_inbox
by Francois Lesueur 19 Dec '24

19 Dec '24

Hello, When dovecot is configured with "acl_defaults_from_inbox = yes", ACL propagation when creating folders seems a bit strange to us. The current behavior is : - INBOX has some ACLs defined in its dovecot-acl file - This ACL is the default for subfolders without a dovecot-acl file inside ("acl_defaults_from_inbox = yes") - When creating a folder, a dovecot-acl file is created inside this folder with a copy of the contents of the dovecot-acl from the INBOX The behavior we expected was : - INBOX has some ACLs defined in its dovecot-acl file - This ACL is the default for subfolders without a dovecot-acl file inside - When creating a folder directly under INBOX, a dovecot-acl file should not be created, as the default from INBOX is already enforced. For subfolders, defaults from INBOX should not be propagated either in the dovecot-acl files. Although dovecot-acl files in subfolders allow to have exceptions, most usage of "acl_defaults_from_inbox = yes" is probably to have mailbox-wide ACLs. In the current behavior, when someone removes an ACL from the INBOX, it will still be present in subfolders, which is error-prone in a setup where users expect that their INBOX ACL is enforced throughout their mailbox. I think that avoiding propagating INBOX ACL when creating a new folder in the case where "acl_defaults_from_inbox" is activated would be more intuitive. Am I missing something ? Cheers, Francois

Recursive doveadm acl add for shared mailbox
by r.barclay＠habmalnefrage.de 17 Dec '24

17 Dec '24

Hello, I have a shared mailbox (e.g. "info(a)example.org") and want to give a new user (e.g. "john.doe(a)example.org") access. I can use: doveadm acl add -u info(a)example.org INBOX user=john.doe(a)example.org create delete expunge insert lookup post read write write-deleted write-seen Unfortunately, the shared mailbox contains several nested folders. And the new user needs to access these, too. So I probably had to use doveadm acl add -u info(a)example.org .INBOX.SubfolderXY user=john.doe(a)example.org create delete expunge insert lookup post read write write-deleted write-seen ... for each and every subfolder. Is there a way to give permissions recursively? INBOX and all (sub-)subfolders? And, by the way, do I have to use doveadm acl recalc -u info(a)example.org OR doveadm acl recalc -u john.doe(a)example.org after that? At the moment I always do both. Thank you! Reg

dovecot configuration question userdb driver
by Stanislav 17 Dec '24

17 Dec '24

Greetings, I have a mail server for a few folks, basically my family. My current Dovecot configuration is the following, which works like a charm: ========== passdb { driver = sql args = /usr/local/etc/dovecot/dovecot-sql.conf.ext } userdb { driver = static args = uid=981 gid=981 home=/var/mail/virtual/%d/%n/home } ========== I've decided to deploy Solr to be able to search faster. Now, when I try to execute "doveadm index -A inbox" I get an error "Error: auth-master: userdb list: User listing returned failure" because I'm using the static userdb. My question is, how do I implement the listing users feature while using "static driver" or a similar approach? I really want to keep using the template "/var/mail/virtual/%d/%n/home" instead of defining a custom path for each user. So I came up with this idea to replace "static" with "sql" driver for "userdb" since there's "iterate_query" I can use to achieve my goal, tho I have to define "user_query", so I can do something like: ======= SELECT '/var/mail/virtual/%d/%n/home' AS maildir, 981 AS uid, 981 AS gid FROM mailbox WHERE username='%u' and active='1'; ======= However, this is a useless waste of resources since I'm not really querying anything, and I'm not even sure if there's template support (e.g., %d/%n) in there. Appreciate any help Best

Rebuild uuidlist?
by Gandalf Corvotempesta 14 Dec '24

14 Dec '24

Guys i did a mess. A bad script made by me, changed (a lot) of filenames in the maildir, in example almost all email filenames were changed. I think I have to rebuild the UID <> filename mapping because dovecot is still trying to read the old file that doesn't exists anymore (it has a new name) Any suggestions? I think this would lead to a full-download of all messages client side, right ?

Mail gone when recreating a folder in a second IMAP session
by Ewald Dieterich 13 Dec '24

13 Dec '24

I'm running Dovecot 2.3.21 with the mdbox mailbox format. I lose mails (with an asterisk, see below) when I'm doing the following in 2 IMAP sessions: Session 1: Create a folder, save a mail and select it: . create folder . append folder {1} . select folder * 1 EXISTS * OK [UIDVALIDITY 1734013510] UIDs valid Session 2: Delete the folder, create it again, save a mail in it, check the number of messages and the uidvalidity:. . delete folder . create folder . append folder {1} . status folder (messages uidvalidity) * STATUS folder (MESSAGES 1 UIDVALIDITY 1734013511) Everything is as expected until here, the uidvalidity was increased by 1, which makes sense. Session 1: Just do a noop . noop * BYE IMAP session state is inconsistent, please relogin. Dovecot notices that something is wrong and closes the connection. This error is logged: Error: Mailbox folder: Corrupted transaction log file /var/spool/dovecot/user/mailboxes/folder/dbox-Mails/dovecot.index.log seq 2: indexid changed: 1734011270 -> 1734011403 (sync_offset=0) Session 2: Check the folder again: . status folder (messages uidvalidity) * STATUS folder (MESSAGES 0 UIDVALIDITY 1734013512) The mail is gone, uidvalidity was again increased by 1, so this is a new folder. I think the problem is that the folder's transaction log is deleted in session 1 in mail_transaction_log_file_open() when Dovecot notices discrepancies in what it expects: if (ret == 0) { /* corrupted */ if (index->readonly) { /* don't delete */ } else { i_unlink_if_exists(file->filepath); } *reason_r = "File is corrupted"; return 0; } This basically recreates the folder, so now it's empty. Here's the asterisk: I know that technically the mail isn't lost because it's still in the storage file and can be recovered. But it's still ugly. And when I copy a mail from another folder instead of appending it, I can't recover it for the folder because the information that the mail was copied is definitely lost. Can this be fixed in Dovecot?

sieve enotify mixes message body and subject
by Cajus Korn 12 Dec '24

12 Dec '24

Dear Community, I found that the following lines of a sieve filter require ["enotify"]; # rule:[enotify] if true { notify :importance "2" :message "New Message received." "mailto:xyz@somedomain.com"; } results in getting the following reply: [...] X-Sieve: Pigeonhole Sieve 0.5.21.1 (49005e73) Message-ID: <dovecot-sieve-1733953974-73072-0(a)ironman.cajus.name> Date: Wed, 11 Dec 2024 22:52:54 +0100 Subject: New Message received.

Sieve not working again
by christian 11 Dec '24

11 Dec '24

Hello, For the past few weeks, I have been facing an issue where user Sieve scripts no longer work. I have configured the filtering of spam emails marked by Rspamd in a before.sieve script, and that works fine. However, the user scripts created via ManageSieve through the Roundcube webmailer do not function anymore. I suspect that this issue started after a Debian 12.6 system upgrade. Could it be that something fundamentally changed, or is Dovecot not fully compatible with Debian 12? However, I find that hard to believe. Despite repeatedly reinstalling the Dovecot environment and verifying file permissions and configurations multiple times, I haven't been able to resolve the issue. I’ve been running Sieve for over 15 years on various servers and have never encountered such problems. Unfortunately, the sieve_user_log = /var/log/dovecot/sieve.log file is not being created. The directory specified in sieve_trace_dir = /var/log/dovecot/sieve is created, but it only logs actions from before.sieve, not from user Sieve scripts. Here are the relevant settings from 90-sieve.conf: plugin { sieve_extensions = +editheader sieve = file:/var/customers/sieve/%u/;active=/var/customers/sieve/%u/.dovecot.sieve sieve_dir = /var/customers/sieve/ sieve_default = /var/customers/sieve/default.sieve sieve_global = /var/customers/sieve/global.sieve sieve_before = /var/customers/sieve/before.sieve sieve_user_log = /var/log/dovecot/sieve.log sieve_trace_dir = /var/log/dovecot/sieve sieve_compile_binary = yes sieve_trace_level = matching sieve_trace_debug = yes sieve_debug = yes } Here’s a log entry from info_log_path = /var/log/dovecot/dovecot-lda.log: Dec 08 12:57:44 lda(info(a)domain.info)<2664475><r1+hOreJVWcbqCgAF7VarQ>: Info: sieve: msgid=<20241208115741.7792d7fe54743ef8(a)fgfunnelsmail.com>: fileinto action: stored mail into mailbox 'INBOX' Here’s a log entry from debug.log: Dec 08 13:12:55 lda(info(a)domain.info)<2680802><SNQDB0eNVWfi5ygAF7VarQ>: Debug: sieve: Using the following location for user's Sieve script: /var/customers/sieve/info(a)domain.info/.dovecot.sieve However, the script is not being applied.

Trying to track down the source of a corrupted cache error
by Grant Keller 10 Dec '24

10 Dec '24

Recently we have been seeing a steady increase (nothing too crazy, just more than usual) in "Deleting corrupted cache record" log errors. What struck me as weird was that it would be for the same message over and over, indicating that the deleted record was making it back into the cache. Digging into one, I realized that the first error was actually this: Dec 4 19:08:59 b.imapd.sonic.net dovecot[2696]: imap(xxx): session=wnZqMH0oHOViI3NN Error: Mailbox INBOX: Maildir filename has wrong W value, renamed the file from /var/spool/mail/17/62/xxx/cur/1733363505.M428026P1491073.b.imapd.sonic.net,S=8966052,W=12155730:2, to /var/spool/mail/17/62/xxx/cur/1733363505.M428026P1491073.b.imapd.sonic.net,S=8966052:2, Dec 4 19:08:59 b.imapd.sonic.net dovecot[2696]: imap(xxx): session=wnZqMH0oHOViI3NN Error: Mailbox INBOX: Deleting corrupted cache record uid=6430670: UID 6430670: Broken virtual size in mailbox INBOX: read(/var/spool/mail/17/62/xxx/cur/1733363505.M428026P1491073.b.imapd.sonic.net,S=8966052,W=12155730:2,): FETCH BODY[]<11796480.393216> got too little data: 359249 vs 359250 Also worth noting that the emails themselves do have a highly unusual number of carriage returns. What causes this and is there a way to fix it besides deleting the offending message?

I'm trying to follow the instruction https://doc.dovecot.org/2.3/configuration_manual/howto/antispam_with_sieve/ to setup IMAPSieve I cannot find any info on what sieve_pipe_bin_dir should point to. Any references I have found to this point to the old wiki. My current spam learning sieve scripts are in file:/home/vmail/sieve/global/ Should sieve_pipe_bin_dir point to this? Thanks, Leo

Dovecot IMAP Mail latency
by tamilarasan_ext＠iomd.info 05 Dec '24

05 Dec '24

We are working on importing emails from Gmail to Dovecot. During the process, all emails are written to a new directory within the mail folder. For fetching the emails, we are using the IMAP protocol with the imap_tools Python library. After importing, we run the IMAP fetch at 5-second intervals. However, the newly imported emails do not appear immediately. They only become available after 30 to 40 seconds. How can we resolve this issue? What steps can we take to debug and identify the source of the delay?

Dear Dovecot community, I try to migrate a GMail mailbox to Dovecot using `doveadm backup -R imapc:`. Since it seems that GMail disabled the login without XOAUTH2, I cannot figure out how to authenticate dovecot to GMail. Could you point me in the right direction? Thank you in advance! Best regards, Jan Here the commands and config I am using: # dovecot --version 2.3.19.1 (9b53102964) # doveadm -D -c gmail.conf backup -R -u user-gmail imapc: # cat gmail.conf !include /etc/dovecot/dovecot.conf imapc_host=imap.gmail.com imapc_port=993 imapc_ssl=imaps imapc_features=rfc822.size fetch-headers gmail-migration mail_prefetch_count=20 imapc_sasl_mechanisms=XOAUTH2 OAUTHBEARER PLAIN rawlog_dir = /tmp/rawlog imapc_rawlog_dir = /tmp/rawlog imapc_user=user(a)googlemail.com imapc_password=pw # cat /tmp/rawlog/20241118-114553.246444.1.in 1731926753.488821 * OK Gimap ready for requests from <ip> <base64> 1731926753.503819 * CAPABILITY IMAP4rev1 UNSELECT IDLE NAMESPACE QUOTA ID XLIST CHILDREN X-GM-EXT-1 XYZZY SASL-IR AUTH=XOAUTH2 AUTH=PLAIN AUTH=PLAIN-CLIENTTOKEN AUTH=OAUTHBEARER 1731926753.503819 1 OK Thats all she wrote! <base64> 1731926753.806967 + <base64> # cat /tmp/rawlog/20241118-114553.246444.1.out 1731926753.488935 1 CAPABILITY 1731926753.504048 2 AUTHENTICATE XOAUTH2 <base64>
