lmtp with sieve editheader Panic: file edit-mail.c: line 1809 (merge_from_parent): assertion failed

Hi, I have experienced a crash in lmtp delivery on some mails when sieve editheader plugin is used. The first one was an "analytics mail" from azure exchange. I stripped down the mail to the relevant parts that trigger this error. log message: lmtp(johnd)<27019><VM4XLJVVj2OLaQAA/TOvIg>: Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(backtrace_append+0x42) [0x7f3048ca0b72] -> /usr/lib/dovecot/libdovecot.so.0(backtrace_get+0x1e) [0x7f3048ca0c8e] -> /usr/lib/dovecot/libdovecot.so.0(+0xff5eb) [0x7f3048cad5eb] -> /usr/lib/dovecot/libdovecot.so.0(+0xff681) [0x7f3048cad681] -> /usr/lib/dovecot/libdovecot.so.0(+0x542c4) [0x7f3048c022c4] -> /usr/lib/dovecot/libdovecot-sieve.so.0(+0x2e11d) [0x7f304841811d] -> /usr/lib/dovecot/libdovecot.so.0(i_stream_read_memarea+0x74) [0x7f3048cb92d4] -> /usr/lib/dovecot/libdovecot.so.0(+0x10eb05) [0x7f3048cbcb05] -> /usr/lib/dovecot/libdovecot.so.0(+0x10f0a9) [0x7f3048cbd0a9] -> /usr/lib/dovecot/libdovecot.so.0(i_stream_read_memarea+0x74) [0x7f3048cb92d4] -> /usr/lib/dovecot/libdovecot.so.0(i_stream_read+0x3a) [0x7f3048cb94ba] -> /usr/lib/dovecot/libdovecot.so.0(+0x112f51) [0x7f3048cc0f51] -> /usr/lib/dovecot/libdovecot.so.0(i_stream_read_memarea+0x74) [0x7f3048cb92d4] -> /usr/lib/dovecot/libdovecot.so.0(i_stream_read+0x3a) [0x7f3048cb94ba] -> /usr/lib/dovecot/libdovecot.so.0(i_stream_read_data+0x3d) [0x7f3048cb9ddd] -> /usr/lib/dovecot/libdovecot.so.0(io_stream_copy+0x74) [0x7f3048cd28f4] -> /usr/lib/dovecot/libdovecot.so.0(o_stream_send_istream+0x4f) [0x7f3048cd25ef] -> /usr/lib/dovecot/libdovecot-storage.so.0(index_storage_save_continue+0x29) [0x7f3048e5dd39] -> /usr/lib/dovecot/libdovecot-storage.so.0(maildir_save_continue+0x20) [0x7f3048e07930] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_save_continue+0x3a) [0x7f3048ddff3a] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_storage_copy+0xb1) [0x7f3048dd0b71] -> /usr/lib/dovecot/libdovecot-lda.so.0(+0x475b) [0x7f3048eed75b] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0x6439f) [0x7f3048de039f] -> /usr/lib/dovecot/libdovecot-sieve.so.0(+0x52ff4) [0x7f304843cff4] -> /usr/lib/dovecot/libdovecot-sieve.so.0(+0x473e9) [0x7f30484313e9] -> /usr/lib/dovecot/libdovecot-sieve.so.0(+0x482a0) [0x7f30484322a0] -> /usr/lib/dovecot/libdovecot-sieve.so.0(sieve_result_execute+0x1af) [0x7f3048432fbf] -> /usr/lib/dovecot/libdovecot-sieve.so.0(sieve_multiscript_finish+0x218) [0x7f3048446f38] -> /usr/lib/dovecot/lib90_sieve_plugin.so(+0x4030) [0x7f3048ba9030] -> /usr/lib/dovecot/libdovecot-lda.so.0(mail_deliver+0x16f) [0x7f3048eee8ef] lmtp(johnd)<27019><VM4XLJVVj2OLaQAA/TOvIg>: Fatal: master: service(lmtp): child 27019 killed with signal 6 (core dumps disabled - https://dovecot.org/bugreport.html#coredumps) the sieve script only has one addheader line require ["editheader","fileinto","body", "include"]; addheader :last "X-Long-Duration" "XXX"; I will attach doveconf and the lmtp communication. inserted to lmtp with: socat - UNIX-CONNECT:$lmtp_socket <<<"$(<$file)" greetz Matze

Sieve: fileinto a subfolder of inbox
by Federico Fanton 05 Dec '22

05 Dec '22

Hi everyone! I'm trying to write a sieve script that moves emails to a *subfolder* of the inbox. My script: require ["envelope", "fileinto", "mailbox"]; if anyof( address "to" "support(a)domain.cc", address "cc" "support(a)domain.cc", envelope "to" "support(a)domain.cc" ) { fileinto :create "INBOX.support"; } But this creates a new "support" folder BESIDE the inbox, not INSIDE it. I've tried replacing "INBOX.support" with "INBOX/support" but then I get an error: "Name must not have '/' characters" Is there something else I could try? Here is the output of dovecot -n: # 2.3.4.1 (f79e8e7e4): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.4 () # OS: Linux 4.19.0-21-amd64 x86_64 Debian 10.0 ext4 auth_mechanisms = plain login lda_mailbox_autosubscribe = yes mail_location = maildir:/home/vmail/maildir/%d/%n/Maildir mail_plugins = " zlib lazy_expunge" mail_privileged_group = vmail 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 { hidden = yes list = no location = maildir:/home/vmail/maildir/%d/%n/Maildir/expunged prefix = .EXPUNGED/ separator = / } namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } passdb { args = scheme=SHA1 /etc/dovecot/users.conf driver = passwd-file } plugin { lazy_expunge = .EXPUNGED/ sieve = file:~/sieve;active=~/.dovecot.sieve sieve_vacation_default_period = 1d sieve_vacation_to_header_ignore_envelope = yes } protocols = imap sieve service auth { executable = /usr/lib/dovecot/auth unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener /var/spool/postfix/private/dovecot-auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { group = vmail mode = 0600 user = vmail } } service doveadm { inet_listener { port = 24242 } } service imap-login { process_limit = 200 } service stats { unix_listener stats-reader { group = vmail mode = 0660 user = vmail } unix_listener stats-writer { group = vmail mode = 0660 user = vmail } } ssl_cipher_list = ALL:!LOW:!SSLv2:ALL:!aNULL:!ADH:!eNULL:!EXP:RC4+RSA:+HIGH:+MEDIUM 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 } userdb { args = uid=1001 gid=1001 home=/home/vmail/maildir/%d/%n allow_all_users=yes driver = static } protocol lda { mail_plugins = " zlib lazy_expunge sieve" } protocol imap { imap_client_workarounds = delay-newmail mail_max_userip_connections = 20 } local 192.168.2.0/24 { doveadm_allowed_commands = sieve list,sieve get,sieve put,sieve activate,sieve deactivate doveadm_password = # hidden, use -P to show it } Many thanks for your time!

Backups and disaster recovery
by GDS 04 Dec '22

04 Dec '22

Hello all! After reading some of the past threads on backups, I was wondering if I could get a sanity check... I run a Maildir configuration for a small (10 mailboxes) mail server. Using "doveadm backup", for each mailbox I do: - Weekly full backups and then copy the files to a network-based filesystem.- Daily incremental backups and then copy the files to a network-based filesystem. My recovery assumption is that in case of hardware failure, I would re-set up the mail service and for each mailbox I will recover at the right directory the latest full mailbox backup and on top of it, each incremental backup to the latest day. Does this sound like a sound strategy? Also, I was thinking of setting up a second dovecot server on another server and replicating my primary on an hourly basis to decrease recovery time. But I looked at mbsync and it seems to require mailbox login/password for each mailbox (which I don't have). Is there an alternative? Thank you!

HIGHESTMODSEQ not increasing
by Ronny Forberger 04 Dec '22

04 Dec '22

Hi, I have a problem with my Dovecot IMAP Server on Debian Linux. I migrated it from FreeBSD to Debian, but since then the HIGHESTMODSEQ value for INBOX is not increasing, when I receive new e-mail. This causes my Groupware not to report any new e-mail via ActiveSync. Here is the protocol transscript: [I] <~>-> openssl s_client -crlf -connect mail.forberger-online.de:993 CONNECTED(00000003) [...] --- read R BLOCK * OK [CAPABILITY IMAP4rev1 SASL-IR LOGIN-REFERRALS ID ENABLE IDLE LITERAL+ AUTH=PLAIN AUTH=LOGIN] Dovecot (Debian) ready.

The Groupware's IMAP client library is reporting, that MODSEQ is not increasing. It stays at 190086, nevertheless I receive new e-mail. I have tried the commands doveadm index and doveadm force-resync on the INBOX, without any change. My filesystem where the mailboxes reside is on ext4. Can you help me what is wrong?

Doveadm Move Query

I have a production Dovecot problem and although I searched the mailing lists, I could not find an answer and I hope you can give me a quick answer/pointer in the right direction. I have mails for a user (user(a)domain.net) under /var/spool/mail/virtual/ domain.net/user and I want to move ALL the mails to /var/spool/mail/virtual/domain.com/user If I use #doveadm -Dv move -u user(a)domain.net Maildir:/var/spool/mail/virtual/ domain.net/user Maildir:/var/spool/mail/virtual/domain.com/user ALL I get doveadm(root): Fatal: Unknown argument MAILDIR:/var/spool/mail/virtual/ domain.com/user if I use #doveadm -Dv move -u user(a)domain.net Maildir:/var/spool/mail/virtual/ domain.net/user /var/spool/mail/virtual/domain.com/user ALL doveadm(root): Fatal: Unknown argument /var/spool/mail/virtual/ domain.com/user What the hell am I doing wrong!? :) Thanks.

bug: ARGON2 hash selection incompatible with LDAP
by Krisztián Szegi 25 Nov '22

25 Nov '22

Good day to all, this is my first post to the mailing list! I'd like to report that non-binding auth to (Open)LDAP doesn't work if the latter hashes passwords with ARGON2. Although dovecot (I am using http://2.3.19.1) does support ARGON2 with libsodium, but it doesn't recoginize hashes beginning "{ARGON2}$argon2id$" stored (and hashed, using ppolicy module's hashCleartext) by OpenLDAP. Now, I understand that ARGON2I, -D, and -ID are not compatible, but the ACTUAL algorithm is there between the two $. Furthermore, I think dovecot is in the minority here, I haven't met any software that specifies the ARGON2 subtype between {}. BTW, I haven't met any software that hashes passwords with ARGON2, but not with the ARGON2ID subtype (where libsodium is available, which also seems to be the standard here), as THAT is the recommended one anyway. I patched the rpm in OpenSUSE repo to alias {ARGON2} to {ARGON2ID}: https://build.opensuse.org/package/view_file/home:Samonitari:branches:openS… Could we get something like this (but maybe more correct) into the official source? Maybe a config switch to alias it runtime? Thanks for the attention: Krisztián

compiled sieve files svbin ?
by jeremy ardley 23 Nov '22

23 Nov '22

Hi, I have recently started using claws mail to manage my user sieve scripts using server dovecot-sieve_1%3a2.3.13+dfsg1-2_arm64.deb I originally edited ~/.dovecot.sieve to hold my script and I recall that ~/.dovecot.svbin was automatically generated on first use. (either that or I have forgotten that I had used sievec) Later I used claws mail to generate sieve scripts but they were written into directory ~/sieve/ In experimentation I changed ~/.dovecot.sieve into a link to my principal script ~/sieve/main.sieve The oddity now is that sieve seems to be working when there is no compiled version Should I expect a compiled .svbin version to be generated from claws client? Or generated by first run of the sieve server on the user account? Or should I manage the scripts with claws, but log in to the server later to generate the .svbin versions? In any event what effect does not having a .svbin version have on typical small installation? -- Jeremy

Dovecot 2.2 to 2.3 migration
by Markus Wienhöfer 17 Nov '22

17 Nov '22

Hi, we are currently using Dovecot 2.2 (from the Ubuntu 18.04 repos) and would like to migrate to 2.3 I have read the migration documentation regarding the configuration changes. Apart from that, is it feasible/possible to change from Ubuntu to official Dovecot repositories and upgrade the dovecot package this way? Or is there anything else we should be aware of? Best regards Markus

Doveadm backup stateful synchronization trouble
by dovecot＠f-hamelin.fr 16 Nov '22

16 Nov '22

Hi, The non-blocking error is: doveadm(user1s@domain): Error: Saved sync state is invalid, falling back to full sync: Invalid base64 data This error occurs every time on my test machine (no traffic, only a few test messages). That error sometime also occurs on my production system, but not each time. The command I used for the first time is : doveadm backup -A -s "" -d > state.txt After that there is a daily calls (as vmail user, my config only handle virtual users) to : doveadm backup -A -s "$(<state.txt)" -d > state.txt.tmp && mv state.txt.tmp state.txt doveconf -n output is available at https://www.f-hamelin.fr/pub/doveadm-backup-doveconf.txt Any help will be welcomed Best regards, Franck

OAUTH2 local validation
by Felix Auringer 16 Nov '22

16 Nov '22

Hello, <https://doc.dovecot.org/configuration_manual/authentication/oauth2/#local-v…> describes how to set up local validation for OAUTH2 with dovecot. This works fine as long as the keys are not rotated. In my experience, it is common for a client to try to validate a token with the cached key and update the cached keys when the local validation fails (e.g. via the /auth/realms/<realm>/protocol/openid-connect/certs endpoint in Keycloak). This way, the client does not need to fetch new keys periodically but only when the old ones expired. If I understand it correctly, Dovecot reads the keys from a defined path but does not care how to update them. Did you have a nice way in mind how the keys should be refreshed when deciding not to do that in dovecot? Are you planning to add automatic refreshing of local validation keys to dovecot? I am running dovecot in Docker and one way would be a cron job on the host that fetches new keys and updates the files inside the container via docker exec. It would work but it's not really a nice solution because from outside dovecot, the information whether the old keys are no longer valid, is not available and the whole process needs to run periodically (and thus way more often than actually necessary).

Re: bug: ARGON2 hash selection incompatible with LDAP

I cannot specify bind_dn template due to mismatched mail addresses and user DNs, and I thought that that would be suboptimal due to re-binding. I am a bit confused about how to optimize LDAP lookups now (static files not option :), re-reading the docs it just made me question more things - auth_bind_dn cannot be given in my case, as a fixed starting point - auth_bind adds a temporary binding (using pass_filter) - can I use userdb prefetch? Docs say I cannot if I use bind with template, but I am not using the latter. So the search for the user's dn during auth IS the passdb lookup? - assuming I am correct, I should give back stuff with passdb lookup: or do I? - Must I give back userid an guid? 10-mail.conf has "vmail" for both, as mail accounts don't have UNIX ones linked to them... - same for home? There is no default I've given until userdb lookup. Just specify a global mail_home with variables, and get on with life? -if I should give back one, should I pass it with default_fields = userdb_home (currently I specify it under default_fields:home in userdb lookup as LDAP doesn't override home). The docs are confusing around userdb. The main thing what is not clear that they CAN override fields on a per-user basis, but must they provide them for non-extra fields, when there are global settings for those? Thanks! BTW, thanks for the great software all of you. Michael, I've come across some of your work, you have my respect!

Accessing Shared Mailbox not working

Hi, I'm new on this mailing list and I'm struggling with the configuration of shared mailboxes. I've followed the following documentation page : https://doc.dovecot.org/configuration_manual/shared_mailboxes/shared_mailbo… and manage to had it working for something like 2 minutes, but then changed a parameter and can't get it back working (and of course I don't remember which one it was).

R: Dovecot 2.3 shared namespace issues
by Stefano Cecconello 15 Nov '22

15 Nov '22

Hello, My bad, the OS was ubuntu 20.04 and not 22.04 . After further tinkering\testing, it seems that removing the " acl_ignore_namespace = shared/* " setting did the trick, now we're getting the correct ACL on client side . Without it we can see the folder with the right permissions : Logging as user01 : shared\Sharer01\INBOX : '[NONEXISTENT] Mailbox doesn't exist: shared/test.imapsharer01(a)td01.testdomain.it/INBOX'' shared\Sharer01\subfolder01 ( RW ) : 'shared/test.imapsharer01(a)td01.testdomain.it/subfolder01 test.imapuser01(a)td01.testdomain.it akxeilprwtscd '] shared\Sharer01\subfolder02ro ( RO ) : '[NOPERM] You lack administrator privileges on this mailbox' Logging on Thunderbird and other IMAP clients ( sylpheed\claws ) as user01 : - It list correctly the shared folders as subscribed folders ; - can't view the mail contents of the sharer INBOX, as desired ; - show the total elements of the sharer INBOX, even if the user01 didnt have access ; If the config is correct, this is somehow what we're trying to accomplish, i have some concerns regarding how it is possible to show the total messages of the remote INBOX without having any privileges . Maybe is something related to the index of that INBOX folder that is somewhat read by the accessing user even if IMAP-wise didnt have any ACL \ rights . I still dont understand why enabling the acl_ignore_namespace setting, results in a : - remote INBOX full control, even if it was not defined in any acl ; - subfolders ACL applied correctly Hope that someone can shed a light on it . Thanks Stefano

Re: bug: ARGON2 hash selection incompatible with LDAP
by Krisztián Szegi 15 Nov '22

15 Nov '22

Sorry, I wanted to post from this alias, but From-Address isn't saved with my drafts :) I failed to recognize during my patchwork that the verification function is the same for ARGON2I and -ID: both call `verify_argon2`, which in turn calls `libsodium's crypto_pwhash_str_verify`. In the new light this, there is no "harm" in my patch: - If backend gives back "{ARGON2}...", dovecot verifies with the same call anyway, regardless of what subtype it actually is, i.e.: {ARGON2I} will work too. - If dovecot generates the hash, the prefix will be the one set by the config's default hash, so for backwards comp., "{ARGON2ID}" could be used if someone wants that. Dovecot will succeed in verifying {ARGON2} generated by itself as well.

Dovecot 2.3 shared namespace issues
by Stefano Cecconello 15 Nov '22

15 Nov '22

Hello, We're trying to configure the shared mailbox feature\namespace on a dovecot 2.3 installation . OS : Ubuntu 22.04 x64 Dovecot : 2:2.3.19.1-2+ubuntu20.04 Our test enviroment is based on a dovecot frontend ( director + proxy ) and a dovecot backend ( auth and storage ), later we will think about increasing the number of backends and frontends ( if we got it right, as we plan to use multiple backends, we should use imapc in order to bind the sharer and the accessing user to the same backend ) . On dovecot backend we've configured the new shared namespace, as stated in the documentation ( https://doc.dovecot.org/configuration_manual/shared_mailboxes/shared_mailbox es/#user-shared-mailboxes ) : -- Dovecot conf -------------------- # Maildir's location is under home dir, which is returned by userdb. mail_location = maildir:~/Maildir:VOLATILEDIR=/tmp_lock/%2.256Nu/%u # Quota, mail_log plugins enabled everywhere mail_plugins = quota notify acl fts fts_lucene mail_log mailbox_alias virtual # Default namespace namespace { hidden = no inbox = yes location = prefix = separator = / type = private mailbox Sent { special_use = \Sent auto = create } mailbox Trash { special_use = \Trash auto = create } mailbox Drafts { special_use = \Drafts auto = create } mailbox SPAM { special_use = \Junk auto = create } } # namespace used by virtual search namespace { prefix = VrtSearch. separator = / location = virtual:/etc/dovecot-common-backend/virtual:INDEX=~/virtual hidden = yes subscriptions = no inbox = no list = no } # IMAP SHARING FEATURE service dict { unix_listener dict { mode = 0600 user = vpopmail group = vchkpw } } plugin { acl = vfile acl_ignore_namespace = shared/* acl_shared_dict = proxy::acl-mysql } dict { acl-mysql = mysql:/etc/dovecot-common-backend/dovecot-dict-sql.conf.ext } # namespace used for IMAP sharing feature namespace { type = shared separator = / prefix = shared/%%u/ location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u list = children subscriptions = no } -- Dovecot dict sql -------------------- # IMAP SHARING FEATURE connect = host=x.x.x.x dbname=xxxxxx user=xxxxxx password=xxxxxx map { pattern = shared/shared-boxes/user/$to/$from table = imap_user_shares value_field = dummy fields { from_user = $from to_user = $to } } map { pattern = shared/shared-boxes/anyone/$from table = imap_anyone_shares value_field = dummy fields { from_user = $from } } -- Dict DB contents -------------------- mysql> select * from imap_user_shares; +------------------------------------------+-------------------------------- --------+-------+ | from_user | to_user | dummy | +------------------------------------------+-------------------------------- --------+-------+ | test.imapsharer01(a)td01.testdomain.it | test.imapuser01(a)td01.testdomain.it | 1 | +------------------------------------------+-------------------------------- --------+-------+ For our tests, we've : - created two users test.imapsharer01(a)td01.testdomain.it test.imapuser01(a)td01.testdomain.it - Created two INBOX subfolders on the sharer01 user, giving user01 those permissions : subfolder01 giving to user01 Full control subfolder02ro giving to user01 list and read - logging as user01 with thunderbird, we see the shared namespace tree : shared test.imapsharer01(a)td01.testdomain.it subfolder01 subfolder02 we're able to see the contents of each folder, even the INBOX . Checking the folder properties, thunderbird reports that the user01 has full control on the INBOX of shared01 .

Questions around mailcrypt and LDAP
by Andre Rodier 15 Nov '22

15 Nov '22

Hello, all. I read carefully the messages about mailcrypt on the mailing list, especially this response from Aki: > It's best suited for securing external storage such as NFS or object storage. > There are possibilities to encrypt the key using user's password, but this > takes careful planning. The keys can also come from userdb , e.g. LDAP. I am able to extend the LDAP schema of my OpenLDAP server to store a key into LDAP attribute for each user. In this case, would it be enough for Dovecot to encrypt the messages when they arrive ? Maybe I misunderstand the documentation. Even when using user keys protected by a password, the Dovecot LMTP process should be able to encrypt the emails with user’s public key, without a password, no ? Ideally, I would like to store user's emails encrypted, so each users cannot access other user's emails. I don't need folder sharing. Thanks for your advice. Kind regards, André Rodier

Dovecot not offering TLSv1.2 after a few minutes
by Markus Wienhöfer 14 Nov '22

14 Nov '22

I have a very strange problem with one of our Dovecot servers (2.2.33.2) on Ubuntu 18.04. The current configuration allows for TLSv1 to TLSv1.3 connections. I can verify those using testssl.sh, the tests will succeed (although correctly mentioning, that TLSv1 and TLSv1.1 should be disabled). Running the tests again after about 5 minutes, the results are different. TLSv1.2 now shows "not offered and downgraded to a weaker protocol". Has anybody experienced a similar problem before? Best regards Markus

Dovecot 2.3.19.1: BUG: Mailbox renaming algorithm got into a potentially infinite loop, aborting
by Ralf Becker 14 Nov '22

14 Nov '22

I found this from 2019 on the list: https://www.mail-archive.com/dovecot@dovecot.org/msg78898.html Timo mentioned it's tracked internally as DOP-1501, but I could find nothing about it being fixed on the (public) list. Any news about that and is the workaround of deleting dovecot.mailbox.log* and dovecot.list.index* still the recommendation, when running into this bug.

Submission: track authenticated_user
by itanguy＠univ-brest.fr 10 Nov '22

10 Nov '22

Hello, We would like to use Dovecot Submission to have less queues to maintain. The relayhost (Postfix) after Dovecot routes mail by sender_map, so authenticated user, not the "mail from" because . For what we've seen, we can't use receive header to retrieve this authenticated_user. Example of header : Received: from mailhost ([0.0.0.0]) by submission.host with ESMTPSA id submission-id (envelope-from<myadress(a)example.com>) for<myadress(a)example.com>; Thu, 9 Nov 2022 08:27:41 +0000 So we've thought to use X-client, but reading the doc seems that's not the a good way : /https://doc.dovecot.org/settings/core// - submission_relay_trusted If enabled, the relay server is trusted. Determines whether we try to send (Postfix-specific) XCLIENT data to the relay server (only if enabled). But, XCLIENT for Submission seems to not transfer LOGIN : /https://doc.dovecot.org/settings/core/ / XCLIENT command can be used to override: Session ID Client IP and port (|%{rip}|,|%{rport}|) HELO - Overrides what the client sent earlier in the EHLO command LOGIN - Currently unused PROTO - Currently unused |forward_*| fields can be sent to auth process’s passdb lookup The trust is always checked against the connecting IP address. Except if HAProxy is used, then the original client IP address is used. Do you know another way to inform the relayhost of submission of the authenticated_user? Thanks Ismaël TANGUY

Help with configuration?
by Ellie McNeill 10 Nov '22

10 Nov '22

Hi, I'm running my own mail server on Debian 11 with exim and Dovecot 2.3.13. I have it working, but I'm seeking advice on further customising my setup. I'm using the Maildir++ format with some personal folders. I use IMAP to retrieve mail and Dovecot's submission server to send mail. 1. I want to have incoming emails automatically placed in certain folders instead of 'Inbox' based on certain criteria. For example, I want all emails from PayPal to go into the 'PayPal' folder and all emails from the Debian mailing list to go into the 'Debian' folder. Can dovecot do this for me and what is the best approach? 2. When I delete an email using my user client, it is only 'marked' as deleted (Thunderbird places a scored line through it, and a 'T' is added to the filename in the Maildir). How can I get dovecot to automatically move mail marked 'deleted' to the Trash folder each time? I also want further delete operations on any mail in the 'Trash' folder to be permanently deleted. 3. I want to hide my client IP address from the headers when submitting mail to Dovecot's submissiond, but I can't seem to find any way to disable this. I would prefer that recipients only see the server IP address, but not the IP address of the mail client which submitted it. Regards, Ellie PS - When signing up for the mailing list, there was no selection ability on the question "Would you like to get replies to your mails only to the list, ie. add a Reply-To header?"

Someone has probably already replied to this, but it's a typo: the OP wanted to say "store". The certificate you created was used to sign itself ("self signed") and thus, asserts its own validity. If you need *other* people to trust your SSL service, you should sign your certificate using a third party authority (e.g. LetsEncrypt) to sign it. Most internet users will have these third party signing authority's certificates in their certificate store to validate your service certificate. If this is for your own personal use (i.e. you don't care about trust since you know it's your own certificate), you have to add your self-signed certificate into *your* system's certificate authority store so that your mail reader does not complain about an untrusted certificate. Clear? Joseph Tam <jtam.home(a)gmail.com>

doveadm backup|sync works for every folder but INBOX

09 Nov '22

I'm trying to migrate an old Cyrus 2.5 server to Dovecot 2.3.19 using doveadm backup -R, which works for all folders but the INBOX itself, which always stays empty. The Cyrus side uses altnamespace:no and unixhierarchysep:no, it's used as imapc: remote in doveadm backup -R with imapc_list_prefix=INBOX Dovecot uses the following namespace to migrate into: namespace inboxes { inbox = yes location = mailbox Sent { auto = subscribe special_use = \Sent } ### some more folders omitted ### prefix = INBOX/ separator = / subscriptions = no } I use the following command line for the migration: doveadm -o imapc_features='rfc822.size fetch-headers' -o mail_prefetch_count=20 -o namespace/subs/location=mbox:/var/dovecot/subs -o imapc_user='someuser' -o imapc_password='secret' -o imapc_host=<cyrus-ip> -o imapc_list_prefix=INBOX -D backup -f -n INBOX/ -R -u someuser@somedomain imapc: The debug output contains the following lines: Nov 02 10:16:01 dsync(someuser@somedomain): Debug: brain S: Namespace INBOX/ has location imapc: Nov 02 10:16:01 dsync(someuser@somedomain): Debug: brain M: Local mailbox tree: INBOX guid=d8d5a3122bce5f63ef9101001ebfc848 uid_validity=1667223083 uid_next=1 subs=no last_change=0 last_subs=0 Nov 02 10:16:01 dsync(someuser@somedomain): Debug: brain S: Local mailbox tree: INBOX guid=c92f64f79f0d1ed01e6d5b314f04886c uid_validity=1577952633 uid_next=32691 subs=no last_change=0 last_subs=0 Nov 02 10:16:28 dsync(someuser@somedomain): Warning: Mailbox changes caused a desync.

In a tcpdump of the IMAP trafic I can see a STATUS "INBOX" (UIDNEXT UIDVALIDITY) but no EXAMINE "INBOX" or something else I would expect from the sync. I can provide the full output of doveadm backup/sync and a pcap of the IMAP trafic, but not to the public list. Any idea what's wrong with the sync of the INBOX or other suggestions / imapc parameters to use?

"Mailbox isn't a valid MBOX file" Error
by Elise 06 Nov '22

06 Nov '22

Running currently two local mailclients: Outlook 2021 and Thunderbird 102.4.2 When using TB and remove a message on my main account, I get this error: [CANNOT] Mailbox isn't a valid mailbox On any other TB configured email accounts I can remove messages without any problems. First I thought that Outlook might block removal on messages, but the issue appears as well if I close that mail client. Can you tell what is causing this problem? Best regards, Jos Chrispijn

Any update on lazy load SNI?
by Pierre Allétru 03 Nov '22

03 Nov '22

Hi folks, We need to use SNI with Dovecot at a relatively large scale and I was wondering if there's any update on the ability to: 1 - Lazy load SNI certificates when they are needed instead of loading them all at once during startup/reload, thus taking a lot of memory and being very slow. 2 - Not having to reload Dovecot every time a new domain cert is added in conf. 3 - Or at least have Dovecot keep processing clients while the slow reload happens. This has been asked already in a 2016 thread: https://www.dovecot.org/pipermail/dovecot/2016-November/106075.html. Regarding point 3 there's a reply from Aki saying it was in the internal tasklist ( https://www.dovecot.org/pipermail/dovecot/2016-November/106089.html) Anybody knows if some progress has been made on these subjects? I can't anything in the docs or any recent information anywhere else. Thanks, -- Pierre Allétru 06 70 55 08 35 pierre.alletru(a)gmail.com

I recently stumbled upon the following commit on the Dovecot core Github repository: https://github.com/dovecot/core/commit/4a187116dc2311804be22724007d35732300… Apparently, Dovecot Director is going to be removed in the next major version of Dovecot and the commercial Dovecot cluster architecture will be its successor: https://github.com/dovecot/documentation/blob/a85b742ec4fc2744db30a6943b3c2… This would be a huge blow for many organizations around the world that are currently using Dovecot with Director in a shared storage environment. Can anyone of the Dovecot developers maybe enlighten us about the future of Dovecot? - Will there still be the Director feature in the next community release of Dovecot? - If not, will there be a community feature that is on par with the current Director feature? - For how long will Dovecot version 2.3 still be supported (security fixes, bug fixes)? Is there any EOL plan? Thanks for any clarification! Steff

Dovecot does not start on MacOS Monterey
by Doro Rose 30 Oct '22

30 Oct '22

Hi, this is a duplicate of the "Dovecot does not start on MacOS Monterey 12.01" thread. I’m still seeing this on dovecot 2.3.19.1. Is there a recommended workaround? The last post in that thread indicated that some modifications in `./src/lib/restrict-process-size.c` might be necessary. Best regards Doro

Mailing list IMAP archive.
by dovecot＠ptld.com 27 Oct '22

27 Oct '22

I am trying to use the IMAP mailing list archive described on https://www.dovecot.org/mailing-lists/ Is this feature still functioning? Using Thunderbird i get an error message that the connection was refused. I don't know if Thunderbird isn't functioning properly (with handling no password) or if the service is down. My end goal is i want to search the archive for solutions before asking the list. Is there a browser based option to search the archives? I didn't see a search option on https://dovecot.org/pipermail/dovecot/

Re: The end of Dovecot Director?

Should be much easier to build a project doing this than forking director. This is my train of thought as well. I believe the following would suffice for most setups. A database with: - Current vhost count per backend server. Alternatively, count the temporary user mappings. - Backend servers. - Temporary user mappings between user - backend server. This database is accessible by all Dovecot proxies in case there’s multiple. Steps when receiving a login: - Check if a temporary user mapping exists. - If so, proxy to the backend server in the temporary mapping. (To do: clean up mappings.) - If not, pick the backend server with the lowest vhost count, create a temporary mapping, then increase the vhost count of the chosen backend server. A monitoring service up/downs backend servers. E.g. by checking the port that we proxy to for each backend server. When a backend server is set to down, kick the user to force a reconnection. (Is that how Director ‘moves’ users?)

Catch all for Metadata storage in SQL database
by Steffen Kaiser 27 Oct '22

27 Oct '22

Hi, the https://doc.dovecot.org/configuration_manual/imap_metadata/ sample uses mail_attribute_dict = file:%h/Maildir/dovecot-attributes which stores all keys=value pairs in the file. http://dovecot.2317879.n4.nabble.com/Dovecot-v2-3-9-3-HTTP-API-Endpoint-for… uses a SQL dict, however very specific ones. How can I use a SQL dict to store _all_ keys, as with a file based storage? I cannot find a documentation for "pattern" specification, that works as "catch all", in order to store anything not catched by patterns into the database. https://wiki.dovecot.org/Dictionary does not give any hint (in my eyes). -- Steffen Kaiser

Dynamically set LDAP user namespace using two attributes
by Thomas Leuxner 26 Oct '22

26 Oct '22

Hi, I’m looking for a way to use two LDAP attributes to create a user-specific namespace to be expunged e.g. mailExpungeTrash=namespace/inbox/mailbox/%{ldap:mailTrashMailbox}/autoexpunge I can create the namespace fine returning the full string to be expunged: mailExpungeTrash=namespace/inbox/mailbox/Deleted\_Messages/autoexpunge However I want to alter the namespace using a second LDAP attribute like: mailExpungeTrash=namespace/inbox/mailbox/%{ldap:mailTrashMailbox}/autoexpunge Regards Thomas

I haven't seen anyone else replying, but there doesn't seem anything anomalous with the output. The session commands-repliesd is is more or less what I expect, although to make sense of this, you'll have to splice the input and output files together using timestamps to see the sequential flow of data. I forget what the symptoms you originally reported, but theoretically, you could simulate either client or server by feeding in the above data and see how the other end behaves. If dovecot is serving out the correct data, then TB is somehow misinterpreting it. > on an uneducated guess, the mailbox is just 'too large' ? > POP has difficulty handling so many files ? Typically, if some resource limit is hit, one side or the other will create a log or notification. Your INBOX is large, but not outrageous. You can test it directly by creating smaller subsets of the INBOX messages and see if the problem goes away. Joseph Tam <jtam.home(a)gmail.com>

Office 365 SSL issue

23 Oct '22

Hi there, I have a bit old Dovecot instance (Ubuntu 14.04 - there is no chance to upgrade it), with these versions of packages: * Dovecot: 2.2.9 * OpenSSL: 1.0.1f Few days ago a client noticed me, that he can't reach his mails through his Office 365. He uses POP3S. I tried to set up a same client for this Dovecot server, but when I configured the POP3 protocoll, after the settings check Office says: Your server does not support the connection encryption type you have specified. Try changing the encryption method. Contact your mail server ...

Change password schema and post-login script
by Christos Chatzaras 23 Oct '22

23 Oct '22

Hello, Question #1: For version 2.3.19.1 these commands use BLF-CRYPT, right? doveadm pw doveadm pw -s CRYPT Question #2: I want to change password schema for current users. For users using POP3 or IMAP I can do it using a post-login script. I have some accounts used only to send e-mails using Postfix, so no POP3/IMAP logins for these accounts. Is any way to change password schema for these accounts?

dovecot mailing list (this mailing list), DKIM, SPF and DMARC
by Lev Serebryakov 22 Oct '22

22 Oct '22

My domain (serebrtyajov.spb.ru) has all these "new" e-mail technologies configured. It works fine till I write to this mailing list. After that I've got several DMARC reports about "spam" from my domain. All these reports are about my mailing list post. I don't have such problems with other mailing lists (FreeBSD ones, OpenJDK ones, and others). Looks like mailing list software for this mailing list is misconfigured. I'm sure, I'll get new after this message. -- // Black Lion AKA Lev Serebryakov

lmtp userdb can't resolve users
by George Asenov 21 Oct '22

21 Oct '22

Hello, I use postfix with dovecot as an lmtp LDA with unix users and multiple domain names and mailboxes in Maildir format placed in domain directory like: /home/mainuser/homes/user(a)domain.tld/Maildir or /home/mainuser/domains/domain2.tld/homes/user(a)domain2.tld/Maildir which have the main user as a group and user@domain.tld/user@domain2.tld as owner Postfix have virtual_alias_maps = hash:/etc/postfix/virtual there in virtual file there is map like: user(a)domain.tld user-domain(a)domain.tld and in /etc/passwd there are actually 2 users with the same home dir and same UID/GID (only the username is different) and in postfix mailbox_transport = lmtp:unix:private/dovecot-lmtp The issue is that when postfix passes the email for local delivery to dovecot lmtp it sends the username as user-domain.tld(a)serverhostname.tld but dovecot is configured with !include auth-system.conf.ext can't resolve this username thus fails to deliver. I've found a workaround in the net to use custom userdb just for lmtp like this: protocol lmtp { mail_plugins = $mail_plugins sieve userdb { driver = passwd-file args = username_format=%n /etc/passwd } } which works but produce some warnings because there is the root user (ID 0) and actually is a dirty workaround Is there more elegant solution??

sieve script is too large (max 1048576 bytes)
by Marc 19 Oct '22

In what section of the config is this limited? I assume it is related to this >go1.13 memory model that allocates quite a lot of vsz?

mdbox vs. maildir format
by Michael 19 Oct '22

19 Oct '22

hey, i am considering changing my mailbox format from maildir to mdbox. the reason for this is mainly, b/c i have (a) multiple large mailboxes with tens of thousands of mail files, and (b) most of these mails files have a size significantly smaller than the sector size of the disk. so, since the emails themselves are only about nGB large, the disk space used is at least twice as much, if not even three times. i know, hard disk space is 'cheap', but still... but then i read at https://doc.dovecot.org/admin_manual/mailbox_formats/dbox/ the following: [...] you must not lose the dbox index files, as they can’t be regenerated without data loss. so, raid is mandatory, which is already the case, but what about backup? how can i achieve a backup/snapshot of both, the mdbox (nfs share) and the index files (local raid) and assure they are consistent? greetings...

Unseen field reported by imap status command returns wrong count for shared mailboxes on dovecot cluster
by Nikolaos Pyrgiotis 19 Oct '22

19 Oct '22

Hello, We recently migrated our mail server to a dovecot cluster of 5nodes, a dovecot proxy, 2directors and 2dovecot backends. All dovecot nodes run version 2.19.1. We use a glusterfs mounted volume on the backends forthe mail storage. We noticed that when issuing the IMAP command to check forUNSEEN messages formails on the shared namespace instead of seeing the value of the unseen messages of the user that the mailbox has been shared to, the value of the unseen messages of the owner of the mailbox is returned. This behavior causes thunderbird when getting new messages forshared mailboxes, to show briefly all messages of the mailbox as unseen forthe user before showing the correct unseen count forthe shared mailbox. The mail location of the shared mailboxes is defined with imapc storage type as described inthe documentation. Is this a dovecot bug? Can we configure a different dovecot configuration setting so that imap status command reports the correct unseen field count when mail location is an imapc storage location? An examples is given below when running doveadm command from one the 2 dovecot directors: When issuing the status command we see that the unseen count is 2: root@doved0-rmt0-cn1:/etc/cron.d# doveadm mailbox status -u npyrgiotis all shared.sysadmins doveadm(npyrgiotis): Info: remote(10.101.0.71:8080): doveadm(npyrgiotis(a)domie02.com)<19078><9l8IJTb+GWOGSgAAEU9A+w>: imapc(10.101.0.75:143): Connected to 10.101.0.75:143 (local 10.101.0.71:33476) shared.sysadmins messages=2 recent=0 uidnext=3 uidvalidity=1662640492 unseen=2 highestmodseq=3 vsize=3950 guid=c92f64f79f0d1ed01e6d5b314f04886c firstsaved=1662643853 shared.sysadmins messages=2recent=0uidnext=3uidvalidity=1662640492unseen=2highestmodseq=3vsize=3950guid=c92f64f79f0d1ed01e6d5b314f04886c firstsaved=1662643853 But when fetching the emails of the mailboxes we can see that the \Seen flag is set for both emails root@doved0-rmt0-cn1:/etc/cron.d# doveadm fetch -u npyrgiotis flags mailbox shared.sysadmins ALL doveadm(npyrgiotis): Info: remote(10.101.0.71:8080): doveadm(npyrgiotis(a)domie02.com)<19074><e7rWDgj+GWOCSgAAEU9A+w>: imapc(10.101.0.75:143): Connected to 10.101.0.75:143 (local 10.101.0.71:38750) flags: \Seen flags: \Seen Below i post the dovecot configuration of one of the two dovecot backends: #
