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. Any ideas please? thanks, Frank doveconf -n # 2.3.21.1 (d492236fa0): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.21.1 (49005e73) # OS: Linux 5.15.149-1-pve x86_64 AlmaLinux release 8.10 (Cerulean Leopard) # Hostname: *** auth_verbose = yes disable_plaintext_auth = no doveadm_password = # hidden, use -P to show it first_valid_uid = 1000 imap_id_send = lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes lmtp_save_to_detail_mailbox = yes log_path = /var/log/dovecot.log login_greeting = IMAP ready. mail_fsync = always mail_full_filesystem_access = yes mail_gid = 1000 mail_home = /srv/mail/mail_storage2/%d/%n mail_location = maildir:~/mail:VOLATILEDIR=/dev/shm/dovecot/%2.256Nu/%u:INDEX=/opt/dovecot/%2.256Nu/%u:ITERINDEX mail_plugins = " notify replication" mail_privileged_group = vpostfix 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 vacation-seconds mbox_write_locks = fcntl mmap_disable = yes namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Spam { auto = subscribe special_use = \Junk } mailbox Trash { special_use = \Trash } prefix = } passdb { args = scheme=CRYPT username_format=%u /etc/dovecot/users driver = passwd-file } plugin { recipient_delimiter = + replication_full_sync_interval = 1 hour sieve = file:~/sieve;active=~/.dovecot.sieve sieve_before = /etc/dovecot/spam-global.sieve sieve_extensions = +vacation-seconds sieve_vacation_default_period = 1d sieve_vacation_max_period = 30d sieve_vacation_min_period = 0 sieve_vacation_use_original_recipient = yes } postmaster_address = ***** protocols = imap pop3 lmtp sieve service aggregator { fifo_listener replication-notify-fifo { mode = 0666 user = vpostfix } unix_listener replication-notify { mode = 0666 user = vpostfix } } service auth { inet_listener { address = 192.168.130.192 port = 3659 } unix_listener /var/spool/postfix/private/auth { group = vpostfix mode = 0666 user = vpostfix } unix_listener auth-userdb { group = vpostfix mode = 0600 user = vpostfix } } service config { unix_listener config { user = vpostfix } } service doveadm { inet_listener { port = 4711 } user = vpostfix } service imap-login { process_min_avail = 1 service_count = 1 } service lmtp { inet_listener lmtp { address = 192.168.130.192 port = 24 } } service managesieve-login { inet_listener sieve { port = 4190 } } service replicator { process_min_avail = 1 unix_listener replicator-doveadm { mode = 0666 user = vpostfix } } ssl_alt_cert = </etc/alt/fullchain.pem ssl_alt_key = # hidden, use -P to show it ssl_cert = </etc/fullchain.pem ssl_cipher_list = PROFILE=SYSTEM ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it userdb { args = username_format=%u /etc/dovecot/users driver = passwd-file } protocol lmtp { mail_plugins = " notify replication sieve" } protocol lda { mail_plugins = " notify replication sieve" } protocol imap { mail_max_userip_connections = 10 mail_plugins = " notify replication quota imap_quota" }

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?

Hello. My sieve script gives an error; "failed with unsuccessful implicit keep".

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

How to deactivate "!include conf.d/auth-system.conf.ext" without touching "/etc/dovecot/conf.d/10-auth.conf"?
by postfix_dovecot＠gmx.de 14 Oct '24

14 Oct '24

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

LAYOUT=index requires mailbox_list _index=yes
by Marc 07 Oct '24

07 Oct '24

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 05 Oct '24

05 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.

Dovecot trying to fetch a directory that contains a typo, couldn't figure out where to fix it
by Yassine Chaouche 29 Sep '24

Dear list, I am encountering an unusual issue where Thunderbird is incorrectly accessing my "Messagerie" folder.

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

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 23 Sep '24

23 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

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. Best Kevin

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.
