Migrating, syncing, maybe load-balancing/failover two dovecot servers?

I am in the process of migrating from dovecot on one OS (macOS/darwin) to a new server running dovecot with another OS (Ubuntu Linux 22.4). I have mostly copied/adapted the setup of the old server to the new. I am in the process of finishing that and adding some stuff that still needs to be added/migrated, like rspamd. And the data of course before the new one takes over from the old. I have done a migration before (MacOS X Server dovecot to MacPorts dovecot on macOS), many years ago, I recall that I used dovecot syncing but also rsync and I don't really recall (and anyway, the software has changed since) I have been thinking about keeping them both alive, with one as a failover for the other. They will not share their storage (e.g. NFS), So, I was wondering if I can do something with syncing between instances and dovecot director. I have been looking at the documentation, but a quick scan reveals I cannot locate some sort of tutorial and I am uncertain what will work and what not. If keeping both alive in parallel is too problematic, it is OK to have regular syncing in one direction (old to new) at first and then switch over and have syncing in the other direction (new to old) Can someone enlighten me?

imap and lmtp create different index/control folders

Hello, We have migrated our mail server from procmail lda to dovecot lmtp/sieve . dovecot imap create the dir with the email account test(a)s32.teststring.ml for name but lmtp create it as test-s32.someteststring.ml(a)serverhostname.tld I can't figure out how to manipulate nor what username postfix send to dovecot/lmtp or how dovecot/lmtp interpret it. As you will see in the config below there is a separate userdb set for lmtp because it receive the username/envelope from postfix as test-s32.someteststring.ml(a)serverhostname.tld which prevent it to use the pam authentication to verify and use the mail user to deliver email. So I use driver = passwd-file which have the option to configure the format of the username. But this is kind of dirty hack which i do not like. Anyone now how to configure dovecot/lmtp by default to remove the @myserverhostname.tld from the username or configure postfix not to add it? Here is the postfix config: ############################# postconf 2bounce_notice_recipient = postmaster access_map_defer_code = 450 access_map_reject_code = 554 address_verify_cache_cleanup_interval

submissiond xoauth2 authentication: line too long
by Tobias Florek 04 Jan '23

04 Jan '23

Hi, I am running the latest container image which has dovecot-submissiond 2:2.3.20-3+debian11 I am running into the following problem. I have successfully set up xoauth2 for IMAP and ManageSieve. Now when roundcube tries to send email to submissiond it fails with 500 5.5.2 Line too long This happens right after roundcube sends AUTH XOAUTH2 dXNlcj10ZkBzY2hhZWZmZXItYWcu[...] (a line of length 2149 characters). Reading RFC 4954, section 4 I suppose that this does not look standard compliant. Am I correct? I will raise this issue with roundcube as well. Cheers, Tobi

CRAM MD5 passwd db permission issue
by Gerben Wierda 04 Jan '23

04 Jan '23

I am busy migrating. I am moving from macOS+MacPorts to Ubuntu+Docker On the old system, I have this in the dovecot config: mail_uid = _dovecot mail_gid = mail mail_privileged_group = mail mail_access_groups = mail This seems weird to me, I think the dovecot user should be in group dovecot only if I understand the docs. On the old system dovecot, postfix, dovenull and rspamd are all members of the mail group. On that system, the cram md5 passwd database (file) has these permissions: drwxr-xr-x 3 root wheel 96 Feb 2 2021 . drwxr-xr-x 22 root admin 704 Jan 4 15:17 .. -rw-r----- 1 root mail 1234 Feb 2 2021 cram-md5.pwd and that has worked like that for many years, basically starting with Mac OS X Server, surviving all kinds of macOS migrations. On my new Ubuntu system I've copied this setup over: drwxr-xr-x 2 root root 4096 Jan 4 09:49 . drwxr-xr-x 7 root root 4096 Jan 4 15:21 .. -rw-r----- 1 root mail 1234 Feb 2 2021 cram-md5.pwd mail_uid = dovecot mail_gid = mail mail_privileged_group = mail mail_access_groups = mail But: Jan 04 15:40:08 auth: Error: passwd-file /etc/dovecot/etc/cram-md5.pwd:open(/etc/dovecot/etc/cram-md5.pwd) failed: Permission denied (euid=91(dovecot) egid=91(dovecot) missing +r perm: /etc/dovecot/etc/cram-md5.pwd, we're not in group 8(mail), dir owned by 0:0 mode=0755) And really, dovecot is in group mail. From /etc/group: mail:x:8:postfix,dovecot dovenull:x:90: dovecot:x:91: And from /etc/passwd: dovenull:x:90:90::/home/dovenull:/usr/sbin/nologin dovecot:x:91:91::/home/dovecot:/usr/sbin/nologin So, that I get this error baffles me.

doveadm proxy list has strange entries
by Tobias Florek 02 Jan '23

02 Jan '23

Hi! I am using dovecot from the latest docker image: Version 2:2.3.20-3+debian11 When getting the proxy list I get the following entries. # doveadm -f flow proxy list username=user(a)example.com proto=imap src ip=10.254.0.13 dest ip=172.23.6.194 port=143 username=username proto=service src ip=src-ip dest ip=dest-ip port=dest-port username=user2(a)example.com proto=imap src ip=10.254.0.13 dest ip=172.23.6.194 port=143 username=username proto=service src ip=src-ip dest ip=dest-ip port=dest-port username=user3(a)example.com proto=imap src ip=10.254.0.13 dest ip=172.23.6.194 port=143 username=username proto=service src ip=src-ip dest ip=dest-ip port=dest-port ... These correspond to the http API's response: # curl -H "Authorization: X-Dovecot-API $(echo -n MY_API_KEY|base64 -w0)" http://localhost:8080/doveadm/v1 -H "Content-Type: application/json" -d '[["proxyList",{},"tag1"]]' | jq [ [ "doveadmResponse", [ { "username": "user(a)example.com", "service": "imap", "src-ip": "10.254.0.13", "dest-ip": "172.23.6.194", "dest-port": "143" }, { "username": "username", "service": "service", "src-ip": "src-ip", "dest-ip": "dest-ip", "dest-port": "dest-port" }, ... ], "tag1" ] ] This does not look right.

Error: Failed to get quota resource STORAGE: quota-fs: quotactl(Q_GETQUOTA, NFS:/home) failed: No such file or directory
by Jorge Concha C. 01 Jan '23

01 Jan '23

Hello everyone, I'm migrating my dovecot (imap) server from CentOS-6 to RockyLinux-9, but I can't get the QUOTA-FS plugin to work. When trying the "doveadm quota get -u user" command, it returns an error "doveadm(user): Error: Failed to get quota resource STORAGE: quota-fs: quotactl(Q_GETQUOTA, nfs:/home) failed: No such file or directory" If the user has his "$home" on a local drive, everything works fine, but if the user has his $home on a nfs-filesystem, it throws that error. On CentOS-6, everything works fine, with the same users on the same nfs-filesystem. I don't know if it is the product of the OS change or the dovecot version change. CentOS6 -> Dovecot 2.2.10 RockyLinux-9 -> Dovecot 2.3.16 Does anyone have any ideas? Thanks -- Jorge Concha C. Área de Sistemas - CEC U. de Chile

Iteration failure on passwd-file when listing all users?
by EML 31 Dec '22

31 Dec '22

Dovecot 2.3.16, Ubuntu 22.04. I'm trying to get a list of all dovecot users, on a simple test setup on my local network (which "works", in that I can get IMAP mails from dovecot): passdb { driver = passwd-file args = /var/mail/vhosts/%d/shadow } userdb { driver = passwd-file args = /var/mail/vhosts/%d/passwd } The command 'doveadm user -u foo(a)example.com' correctly shows that user. However, any attempt to wildcard the user fails: # doveadm user -u *(a)example.com Error: auth-master: userdb list: User listing returned failure Fatal: user listing failed The log file shows Error: conn unix:auth-worker (pid=13471,uid=129): auth-worker<1>: passwd-file(*(a)example.com): passwd-file: User iteration isn't currently supported with %variable paths Any ideas? And, if I can get this to work, is this method any better than just reading /var/mail/vhosts/example.com/passwd and extracting the first field to get the user name? Or just finding all the maildir directories in /var/mail/vhosts/example.com? Thanks. If you're interested, I'm doing this so that I can automate postfix setup (by mapping new addresses to known dovecot users in the postfix virtual mailbox file). The vmailbox file might look like: # 'user1' is a known dovecot user foo(a)example.com example.com/user1

Permissions issue with doveadm mailbox command

I have been exploring dovecot and came across this: $ sudo doveadm mailbox list doveadm(root): Error: Mail access for users with UID 303 not permitted (see first_valid_uid in config file, uid from mail_uid setting).

Sieve duplicates
by Ferenc 28 Dec '22

28 Dec '22

Hi list, I’m trying this again from a different account because of lots of SPF warnings. I have Sieve scripts that duplicate e-mails. I don’t want that. My dovecot version is 2.3.4.1 (f79e8e7e4), Pigeonhole version 0.5.4 on Linux 5.4.189-2-pve x86_64 Debian 10.13. My scripts get called on an imap COPY action (imapsieve extension). The mail is fed to an external script (spam/ham training or retraining) via a pipe :copy action (vnd.dovecot.pipe extension). An header is added to keep track of what happened (editheader extension). I use "if header :contains” for my (simple) logic. If contains header X, do this, add header Y. If contains header Y, do that, add header X. I end each "if” part with “keep;" and “stop;” commands. Simple versions of the scripts, without the if-then construct, seem to work ok with imapsieve. As soon as I try to use if-then-else I find a duplicate of the processed e-mail; the original mail seems to be untouched, the duplicate appears to have been processed. With macos mail not all duplicates show up but with Roundcube webmail I can see them all. The scripts are like this: # without if-then require … pipe :copy … addheader … keep; # with if-then require … if header :contains pipe :copy … addheader … keep; stop; if not exists pipe :copy … addheader … keep; stop; keep; The scripts get called from “imapsieve_mailbox1_before” for example. Cheers, Ferenc

Dovecot v2.3.20 released
by Aki Tuomi 28 Dec '22

28 Dec '22

We are pleased to release v2.3.20 of Dovecot. https://dovecot.org/releases/2.3/dovecot-2.3.20.tar.gz https://dovecot.org/releases/2.3/dovecot-2.3.20.tar.gz.sig Binary packages in https://repo.dovecot.org/ Docker images in https://hub.docker.com/r/dovecot/dovecot Regards, Aki Tuomi Open-Xchange oy -- + Add dsync_features=no-header-hashes. When this setting is enabled and one dsync side doesn't support mail GUIDs (i.e. imapc), there is no fallback to using header hashes. Instead, dsync assumes that all mails with identical IMAP UIDs contains the same mail contents. This can significantly improve dsync performance with some IMAP servers that don't support caching Date/Message-ID headers. + lua: HTTP client has more settings now, see https://doc.dovecot.org/admin_manual/lua/#dovecot.http.client + replicator: "doveadm replicator status" command now outputs when the next sync is expected for the user. - LAYOUT=index: duplicate GUIDs were not cleaned out. Also the list recovery was not optimal. - auth: Assert crash would occur when iterating multiple userdb backends. - director: Logging into director using master user with auth_master_user_separator character redirected user to a wrong backend, unless master_user_separator setting was also set to the same value. Merged these into auth_master_user_separator. - dsync: Couldn't always fix folder GUID conflicts automatically with Maildir format. This resulted in replication repeatedly failing with "Remote lost mailbox GUID". - dsync: Failed to migrate INBOX when using namespace prefix=INBOX/, resulting in "Remote lost mailbox GUID" errors. - dsync: INBOX was created too early with namespace prefix=INBOX/, resulting a GUID conflict. This may have been resolved automatically, but not always. - dsync: v2.3.18 regression: Wrong imapc password with dsync caused Panic: file lib-event.c: line 506 (event_pop_global): assertion failed: (event == current_global_event) - imapc: Requesting STATUS for a mailbox with imapc and INDEXPVT configured did not return correct (private) unseen counts. - lib-dict: Process would crash when committing data to redis without dict proxy. - lib-mail: Corrupted cached BODYSTRUCTURE caused panic during FETCH. Fixes: Panic: file message-part-data.c: line 579 (message_part_is_attachment): assertion failed: (data != NULL). v2.3.13 regression. - lib-storage: mail_attribute_dict with dict-sql failed when it tried to lookup empty dict keys. - lib: ioloop-kqueue was missing include breaking some BSD builds. - lua-http: Dovecot Lua HTTP client could not resolve DNS names in mail processes, because it expected "dns-client" socket to exist in the current directory. - oauth2: Using %{oauth2:name} variables could cause useless introspections. - pop3: Sending POP3 command with ':' character caused an assert-crash. v2.3.18 regression. - replicator: Replication queue had various issues, potentially causing replication requests to become stuck. - stats: Invalid Prometheus label names were created with specific

OT: Two simultaneous POP3 connections from Outlook
by kjohnson＠eclypse.org 21 Dec '22

21 Dec '22

Hello, I recognize this may be somewhat off-topic, but my search-fu has failed to provide useful results, so I ask for pointers to further information. Today, while examining Dovecot logs, I found a case where the Outlook mail client (probably 2016 or later) on a user's computer opened two simultaneous, or at least overlapping, POP3 connections to Dovecot. This did not go well, naturally. Warning: Transaction log file .../mail/.imap/INBOX/dovecot.index.log was locked for 156 seconds (rotating while syncing) If anyone else has found useful information about this peculiar behavior for an email client, I would be pleased to receive a pointer in that direction. Thank you. Ken

I'm using what ever is in Debian Bookworm, I'm pretty sure. These filters? I collect from different email addresses like gmail and that. If filter for the "Sent to" email address, move to this directory If "From" contains "blah", move to this other directory. If something is Sent to and also From contains "blah" then I get 2 copies of the message in both filter directories. How can I fix this? regards mick

feature request: add base64 variable modifier
by alex 19 Dec '22

19 Dec '22

Hi, It would be very convenient to have a base64 variable modifier. Main use-case is to base64-encode passwords when changing your hashing scheme. With a base64 encoding modifier (e.g. %B) something like this would safely work: userdb { driver = prefetch default_fields = plain_pass=%Bw } without things breaking when there are %-characters in the password, and without having to send the plaintext password to the database, as current solutions propose, which is never a good idea. alternative solution: adapt the generic hash-modifier to accept a none/plaintext hashing-scheme and use the base64 output functionality that is already available there. Thanks! Alex

What do I do with the ".ext?"

dovecot 2.3.15 opensuse LEAP 15.4 I am installing dovecot and have postfix as the SMTP agent. It also needs to use a MySQL database. In </etc/dovecot> there is the main dovecot.conf file, and a number of other files with the extension ".conf.ext." It is not clear how to use these. I could nothing in the documentation that discusses it. Do I copy one, say dovecot-sql.conf.ext, modify it: - rename the copy without the ".ext?" - or move the copy to the "conf.d" directory, with or without the "ext?" -- James Moe moe dot james at sohnen-moe dot com 520.743.3936 Think.

2.3.14: stale imap-login processes due to bogus user setup tying up process limit
by Volker Stolz 16 Dec '22

16 Dec '22

I just dealt with an interesting Dovecot issue on our small server, and thought I might share it. I also feel that although in the end it was a configuration error, Dovecot should somehow avoid leaving this processes around and hence filling up the process limit quickly. - set up Dovecot IMAP on Debian buster (either with the older 2.3.x Debian package, or 2.3.14 from the dovecot-repo) - config: ... namespace inbox { inbox = yes location = ... default settings ... ... passdb { args = scheme=HMAC-MD5 username_format=%u /etc/dovecot/users driver = passwd-file } protocols = " imap" ... userdb { args = blocking=no driver = passwd } ... - secret sauce: have a user in the passdb that doesn't have a physical account on the system yet (we were migrating to a new machine). The log-file shows successful authentication for that user (after we flipped DNS to point to this new machine), but over time (2-3 times/day) we were left with an increasing number of `imap-login` processes in state `pre-login`, eventually requiring a dovecot restart. Dialling up process_limits didn't seem to help, we'd just get more of these stale processes. After creating the user on the system, the behaviour reverted to normal, no more stale processes. I do not know what error message that user received on their end, but since we announced we were migrating, they probably just ignored it and thought it as part of the transition. Best, Volker (a happy & long Dovecot user)

Kerberos/GSSAPI auth weirdness?
by r3pek 14 Dec '22

14 Dec '22

Hi list! I'm migrating my server into a new REALM (INT.R3PEK.ORG) from an old one (R3PEK.ORG) This is a completely new install and configuration, so no leftovers exits. The machine is correctly register into the REALM and users are able to login without a problem. Now, when I try to login using a Kerberos ticket, for some reason that I can't understand, dovecot is looking for a ticket on the old REALM. Maybe because of the email domain (which stayed the same)? This is the error message I see on the clients: "Failed to authenticate: Server krbtgt/R3PEK.ORG(a)INT.R3PEK.ORG" The one it should be looking for is krbtgt/INT.R3PEK.ORG(a)INT.R3PEK.ORG, but I can't seem to figure out where the problem is. # doveconf | grep -i realm auth_default_realm = INT.R3PEK.ORG auth_realms = INT.R3PEK.ORG What do I need to change to make this work?

Backups
by Doug Hardie 11 Dec '22

11 Dec '22

I started to investigate using doveadm backup to backup my mail system. I have a small number of users and the mail store is not large. It uses maildir format. I setup a test system that is not connected to the internet and started up dovecot. I used the following command to backup one user: doveadm backup -u ben remote:test ben is the user is in the mail store. Test is the actual server name. That worked just fine. The maildir was copied completely (as best as I can tell with ls). Then I tried the second user: doveadm backup -u jean remote:test This gives 2 error messages: doveadm(jean)[]<McRYOFI0jGN1MwAAmC+70w>: Error: Mailbox INBOX: Failed to get attribute vendor/vendor.dovecot/pvt/server/sieve/files/.dovecot: Mailbox attributes not enabled doveadm(jean)[]<0IwxIlI0jGMgUwAAZU03Dg>: Error: Remote command returned error 65: ssh test doveadm dsync-server -ujean -U In addition, the maildir directories are created, but there are no emails in any of them (e.g., cur).

An header is added to keep track of what happened (editheader extension). I use "if header :contains” for my (simple) logic. If contains header X, do this, add header Y. If contains header Y, do that, add header X. I end each "if” part with keep; and stop; commands. Simple versions of this script, without the if-then construct, seem to work ok. As soon as I try to use if-then-else I find a duplicate of the processed e-mail; one that seems to be untouched, one that appears to have been processed. I hope I’m making myself clear… # without if-then require … pipe :copy … addheader … keep; # with if-then require … if header :contains pipe :copy … addheader … keep; stop; if not exists pipe :copy … addheader … keep; stop; keep; The scripts get called from for instance imapsieve_mailbox1_before. Cheers, Ferenc

Hello, i want to configure seen flags per user for shared public mailboxes in dovecot. I have added the INDEVPVT Option to the location parameter in the namespace and restarted the services and the server. Unfortunately nothing changed and there are still global seen flags in the configuration. In a post i read that i have to manually add some files to the location but this isnt specified in the documentation. below is the version we use and the config. dovecot --version 2.3.13 (89f716dc2) dovecot -n # 2.3.13 (89f716dc2): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.13 (cdd19fe3) # OS: Linux 5.10.0-17-amd64 x86_64 Debian 11.4 ext4 # Hostname: <SERVERNAME> auth_debug = yes auth_debug_passwords = yes auth_verbose = yes auth_verbose_passwords = plain mail_debug = yes mail_gid = vmail mail_location = maildir:/var/mail/user mail_plugins = acl mail_privileged_group = vmail mail_uid = vmail namespace { list = yes location = maildir:/var/mail/public:INDEXPVT=/var/mail/public prefix = public/ separator = / subscriptions = no type = public } namespace { list = yes location = maildir:/var/mail/user/%u/Maildir:INDEX=/var/mail/user/%u/shared/%u:CONTROL=/var/mail/user/%u/shared/%u prefix = shared/%%u/ separator = / subscriptions = no type = shared } namespace inbox { hidden = no inbox = yes list = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = separator = / subscriptions = yes type = private } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile acl_anyone = allow acl_shared_dict = file:/var/mail/database/shared-mailboxes.db } protocols = " imap" service stats { unix_listener stats-reader { group = vmail mode = 0660 user = vmail } unix_listener stats-writer { group = vmail mode = 0660 user = vmail } } ssl_cert = </var/ssl/dove.crt ssl_client_ca_dir = /etc/ssl/certs ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol imap { mail_plugins = acl imap_acl }

access dict in lua auth script
by Tobias Florek 08 Dec '22

08 Dec '22

Hi! I want to access a configured dictionary in a lua authentication script. Unfortunately the documentation <https://doc.dovecot.org/admin_manual/lua/> does mention a dict object but no way to get one. I also did not find any lua tests in dovecot's source code. Is using the built-in dict not supported? Cheers, Tobias Florek

moving messages between namespaces go into purge
by Marc 07 Dec '22

07 Dec '22

I think it would be nice to have an option where the moving of messages between namespaces (by automated server scripts) would not result in messages ending up in the 'purge' queue. Currently when you move these copied messages, they end up in the purge queue combined with messages that users deleted. I am more or less forced to purge the mailbox after moving GB's while I prefer not to do this, because I would like to keep the opportunity to recover from the purge queue. Maybe there is a way to 'deduplicate' this purge queue?

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?

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?

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 . If we try to check the ACL via python script ( imaplib.gestacl ) or via doveadm, we can see that the sharer01 INBOX has no rights for user01 . But via thunderbird ( or other email clients ) we can delete emails . ACL - sharer01 accessing its folder ('OK', [b'INBOX test.imapsharer01(a)td01.testdomain.it lrwstipekxacd']) ('OK', [b'subfolder01 test.imapuser01(a)td01.testdomain.it akxeilprwtscd test.imapsharer01(a)td01.testdomain.it lrwstipekxacd']) ('OK', [b'subfolder02ro test.imapuser01(a)td01.testdomain.it lr test.imapsharer01(a)td01.testdomain.it lrwstipekxacd']) ACL - user01 accessing sharer01 folders ('OK', [b'shared/test.imapsharer01(a)td01.testdomain.it/INBOX']) ('OK', [b'shared/test.imapsharer01(a)td01.testdomain.it/subfolder01 test.imapuser01(a)td01.testdomain.it akxeilprwtscd']) ('OK', [b'shared/test.imapsharer01(a)td01.testdomain.it/subfolder02ro test.imapuser01(a)td01.testdomain.it lr']) Testing with doveadm shows the correct ACL : #

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
by Ralf Becker 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

The end of Dovecot Director?
by Steff Majeur 02 Nov '22

02 Nov '22

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.

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/

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

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

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
by Ervin Hegedüs 23 Oct '22

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 ... While the client was trying, I see these lines in the log: Oct 21 16:12:18 mail dovecot: pop3-login: Debug: SSL: where=0x10, ret=1: before/accept initialization [192.168.8.133] Oct 21 16:12:18 mail dovecot: pop3-login: Debug: SSL: where=0x2001, ret=1: before/accept initialization [192.168.8.133] Oct 21 16:12:18 mail dovecot: pop3-login: Debug: SSL: where=0x2001, ret=1: SSLv3 read client hello A [192.168.8.133] Oct 21 16:12:18 mail dovecot: pop3-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write server hello A [192.168.8.133] Oct 21 16:12:18 mail dovecot: pop3-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write certificate A [192.168.8.133] Oct 21 16:12:18 mail dovecot: pop3-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write key exchange A [192.168.8.133] Oct 21 16:12:18 mail dovecot: pop3-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write server done A [192.168.8.133] Oct 21 16:12:18 mail dovecot: pop3-login: Debug: SSL: where=0x2001, ret=1: SSLv3 flush data [192.168.8.133] Oct 21 16:12:18 mail dovecot: pop3-login: Debug: SSL: where=0x2002, ret=-1: SSLv3 read client certificate A [192.168.8.133] Oct 21 16:12:18 mail dovecot: pop3-login: Debug: SSL: where=0x2002, ret=-1: SSLv3 read client certificate A [192.168.8.133] Oct 21 16:12:18 mail dovecot: pop3-login: Warning: SSL failed: where=0x2002: SSLv3 read client certificate A [192.168.8.133] Oct 21 16:12:18 mail dovecot: pop3-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=192.168.8.133, lip=192.168.8.21, TLS handshaking: Disconnected, session=<9sWMB4zr+ADAqAiF> Which is weird, because I disabled SSLv3.

Change password schema and post-login script
by Christos Chatzaras 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.

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??

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: #

by Serveria Support 18 Oct '22

18 Oct '22

I'm trying to setup Dovecot with mail-crypt plugin with per-user encryption. I have configured mail-crypt plugin as per official guide here: https://doc.dovecot.org/configuration_manual/mail_crypt_plugin/ After that I created a user and an encrypted key by running this command: doveadm -o \plugin/mail_crypt_private_password=12345 mailbox cryptokey generate -u mail(a)example.org -URf (replacing dummy data ofc) I can log in to webmail (and Dovecot) just fine, emails are getting sent and delivered. I have also checked the storage and the messages seem to be stored encrypted. However, I can't read the emails in webmail (just headers can be seen) and in Dovecot logs I can see the following error: failed: Private key not available: Cannot decrypt key ### Cannot decrypt key ### <8632: Password not available (FETCH RFC822.HEADER) There seems to be an issue with mySQL query. The query I'm using (Select username as "user", password,"%w" as userdb_mail_crypt_private_password from mailbox;) seems to work just fine, when run from mysql prompt it outputs the usernames and passwords, but the error is still there (Cannot decrypt key ### Password not available). Any ideas? What am I missing?

sieve script not modifying header
by Marc 17 Oct '22

17 Oct '22

From the command line the sieve script is modifying the header like this: su testuser -s '/bin/bash' -c 'cat test.msg | /usr/lib64/dovecot/sieve-execute/sieve-test' However when executing via dovecot, the header stays unchanged require ["copy","fileinto","vacation","vnd.dovecot.execute","editheader"]; # rule:[testing2] if not execute :pipe "sieve-test" { } Any idea what I am forgetting to configure/allow?

adding caldav/carddav next to dovecot
by Marc 16 Oct '22

16 Oct '22

I hope it is ok to post this off-topic question here. I was wondering if there are here environments running that offer next to dovecot also calendar and contacts services. In the past I was testing a bit with the one from Apple, but I think it is being discontinued because of converting the python 2 code. I am looking for some experience with a setup provisioning >10k users. Not that I have such requirement, but I want to know if the solution is stable, efficient and optionally can scale. I need something efficient, because I do not have to many resources and high iops available. I also do not want any other other 'crap' just the cal (and card) dav solution. https://github.com/1and1/cosmo This looks interesting (used 1und1 in Germany?) but not big community https://sabre.io/dav/install/ This is in php ...

Re: ot: how to t/s TBird problems ?

I suspect you'll need to do session logging e.g. protocol pop3 { ... rawlog_dir = /writable/logdir/%u } then mkdir /writable/logdir/user chmod 0777 /writable/logdir/user to obtain session transcripts of what server/client are doing. I don't see any obvious errors from the logs that indicate any failure. I do see the INBOX is rather large so maybe a timeout is involved. Joseph Tam <jtam.home(a)gmail.com>

Re: LDAP just for passdb
by Francis Augusto Medeiros-Logeay 14 Oct '22

14 Oct '22

Again, a bit more reading got me to adding this to my passdb config: username_filter = *(a)domain-a.com This way, I can control which domains get to authenticate via my ldap backend, which gives me time to design a good way of saving other attributes there. If anyone have other ways of doing this, ie., having multiple domains on ldap/freeipa and getting an elegant integration with Dovecot, I’d be glad to hear.

Re: LDAP just for passdb
by Francis Augusto Medeiros-Logeay 14 Oct '22

I actually saw that it was possible, and it works, but I came across another problem and I wonder if you have any tips about it: On my current dovecot setup, I use SQL as the backend. So I have the following users: francis(a)domain-a.com <mailto:francis@domaina.com> francis(a)domain-b.com <mailto:francis@domain-b.com> Those are separate users which their own mailboxes. However, I have a freeipa that is configured for the `domain-a.com <http://domain-a.com/>` realm. However, since I am using `%n` for the uid search: auth_bind_userdn = uid=%n,cn=users,cn=accounts,dc=domain-a,dc=com And pass_filter = (&(objectClass=posixAccount)(uid=%n)) It of course leads up to both users above being able to authenticate with the same password. Is there a way to limit ldap authentication to just one domain, or perform a search where both username and domain are checked? I could use the `mail``attribute to filter users, but I imagine that if two users have the same mail configured, I’d run into trouble….

LDAP just for passdb
by Francis Augusto Medeiros-Logeay 14 Oct '22

14 Oct '22

Hi, I couldn't find it in the documentation, so I was wondering - is it possible to configure Dovecot to use LDAP for passdb and keep using SQL for userdb? I would like to do that before I come up with a good strategy to expand my ldap schema to support other mail attributes for virtual domains, aliases, etc. I am currently using FreeIPA. Best, Francis

"make check" fail at test_program_refused
by A. Schulze 14 Oct '22

14 Oct '22

Hello, I moved my buildsystem to an other platform (I do not fully control) and now receive this error on "make check" Error: program tcp:127.0.0.2:42027: connect(::1) failed: Connection refused test_program_refused ................................................. : FAILED The build run on jenkins buildnodex spawn up on a kubernetes cluster. What I noticed so far: the buildnode opereate ipv4 only but has an entry in /etc/hosts: 127.0.0.1 c4a84c76f0d6 ::1 c4a84c76f0d6 Maybe that's the glitch ... I tried dovecot-2.3.15 and 2.3.19.1. Both fail (only the portnumber differ) Is there an option to disable only one specific test? I dislike to skip "make check" at all. Andreas

what are the options to 'interact' with a dovecot imap user
by Marc 14 Oct '22

14 Oct '22

I am looking for a user friendly way to have a user to tell the 'server' to either store or remove an email address. a. My first thought was to use imapsieve for this and have an imap sieve plugin store/remove the email address of the message that is being dragged into a predefined monitored folder. This would work with any imap client b. I was thinking about the message Flagged[1]. I am curious how would I be able to detect this (in sieve)? This does not seem to be stored in the source of the message. Although every client seems to support it, it would probably conflict with every day use cases. c. Then you have these colours and/or categories. But these do not seem to propagate across clients. Where are these even stored? Any ideas on how this can be done?

Director hashing
by Dan Conway 14 Oct '22

14 Oct '22

Hello all, I have a 2 node director setup that uses checkpassword for authentication as well as backend assignment through director tags. director_servers = 192.168.1.10 192.168.1.20 director_mail_servers = 192.168.2.10@srv1 192.168.2.11@srv2 checkpassword writes the following to Dovecot on successful authentication: proxy=y\tdirector_tag=<tag>\tport=<port>ssl=yes\tdestuser=<email>\t This seems to work just fine. However, when I attempt to view a users current hash/initial config: # doveadm director status "user(a)domain.com" Current: n/a (expires -1) Hashed: Initial config: I get null data. There does appear to be a hash mapping of some sort however: # doveadm director map -u user(a)domain.com 1140334690 # doveadm director map -h 1140334690 user(a)domain.com The use of doveadm director move has no effect. doveadm reports it moved the user, but it does not: # doveadm -v director move "user(a)domain.com" 192.168.2.11 Info: User hash 1140334690 moved to 192.168.2.11 When using checkpassword and supplying fields to Dovecot, should I also be including another field to populate hashes for director? I could be missing something obvious in the docs. I'm on version 2.3.18 (9dd8408c18). I have not included dovecot.conf due to the size. If someone needs to see it I can supply it.

to add to what file (csr, cert, ca) to get the sni to work again for mail.paulkudla.net so based on the mail lists So in you example a valid .csr now contains: CN = example.com SAN.1 = example.com SAN.2 = www.example.com etc. Of course you could also have: CN = www.example.com SAN.1 = www.example.com SAN.2 = example.com what do i modify (and how) ???? the above says to modify the csr ? please keep in mind that the cert purchased is only for the name : mail.paulkudla.net thus i fail to see why it is throwing error 42, however this seems to be a patch to thunderbird as well i did not have to change the servers base ssl stuff (*.scom.ca) so that is still working or will that need to be updated as well eventually postfix is perfectly fine ?????

One-off backup
by Ian Evans 11 Oct '22

11 Oct '22

I run a small email server for me and the missus. Six dovecot users. Our host is migrating our server instance. They usually (99.9999% lol) go off without a hitch. As we don't have dovecot running elsewhere, I'm assuming doveadm is the wrong tool. If we want to make a one-off backup prior to the migration, is shutting down postfix and running tar czf mailstorage.tgz /path/to/mail okay? Thanks.

Static build problems
by Jacob Welsh 09 Oct '22

09 Oct '22

I'm attempting to build the latest Dovecot, version 2.3.19.1, on Gales Linux, a distribution based on musl libc with all static linking. After working around some expected troubles to generate configure, such as the libtool and iconv.m4 dependencies, the build appeared to complete successfully. But on closer inspection, the plugins were installed as a bunch of .a and .la files rather than getting linked into any of the binaries, as would be necessary to actually use them. I determined that the probe for dynamic module support (DOVECOT_MODULES defined in 'm4/modules.m4') had returned a false positive: in the static configuration musl includes a stub dlopen() that always returns failure at runtime, so a compile-and-link-only test is not predictive. Libtool itself is affected in the same way, but it comes with the --disable-shared option which usually makes things works fine. Short of a proper solution (perhaps removing modules.m4 and going instead by what libtool already determined, since you've decided to depend on it anyway), I stubbed out modules.m4 to simply return the correct result for this platform, thus: AC_DEFUN([DOVECOT_MODULES], [ have_modules=no AC_SUBST(MODULE_LIBS) AC_SUBST(DLLIB) ]) Now the build is failing due to the absence of a function that's defined only when HAVE_MODULES is true: libtool: link: gcc -I../../src/lib -I../../src/lib-test -I../../src/lib-ssl-iostream -DDCRYPT_MODULE_DIR=\"/gales/pkg/dovecot-0.0-2.3.19.1/lib/dovecot\" -DDCRYPT_SRC_DIR=\"../../src/lib-dcrypt\" -std=gnu99 -g -O1 -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -fno-builtin-strftime -Wstrict-aliasing=2 -Wl,--whole-archive -Wl,../lib-ssl-iostream/.libs/libssl_iostream.a -Wl,--no-whole-archive -o test-stream test_stream-dcrypt.o test_stream-istream-decrypt.o test_stream-ostream-encrypt.o test_stream-test-stream.o ../lib-ssl-iostream/.libs/libssl_iostream.a ../lib-test/.libs/libtest.a ../lib/.libs/liblib.a test_crypto-dcrypt.o: In function `dcrypt_initialize': /home/user/gales-linux/gports/dovecot/build/dovecot-2.3.19.1/src/lib-dcrypt/dcrypt.c:34: undefined reference to `module_dir_try_load_missing' collect2: error: ld returned 1 exit status make[3]: *** [Makefile:664: test-crypto] Error 1 I noticed commit d21897832a443d139d56b1fb1c86d8f76e5f77f3 from 2009, "Fixed compiling without module support", and clearly it's supposed to work since the #ifdefs are there, but I begin to suspect that nobody's actually tested this branch of the configuration tree recently. Further, looking through the automakefiles I'm not finding how the plugin libraries are supposed to work at all in this case and I begin to fear that they simply... aren't. Say it ain't so? Jacob

imapsieve removeflag ignored
by Slavko 08 Oct '22

08 Oct '22

Hi, i have working SPAM reporting implementend by imapsieve in debian's 2.3.13 dovecot. Recently i decide to add personal spam filter by bogofilter and use logic to learn/unlearn SPAM/HAM based on message flags. Here is example of moving message from Junk folder (the opossite logic is similar): if hasflag "$Junk" { execute :pipe "bogofilter" ["-Sn"]; removeflag "$Junk"; debug_log "Learned HAM (and unlearned)"; } else { execute :pipe "bogofilter" ["-n"]; debug_log "Learned HAM (only)"; } # mark as learned addflag "$NotJunk"; report ... When i move message, the debug lines in log shows, that logic works and flag is added as expected, but the other flag is not removed. Thus after moving mail from Junk, which has $Junk flag, it has both flags, the $Junk and $NotJunk. I tried to move removeflag action outside of condition and add it just before addflag, but the result is the same. For now i do not know if here is something wrong in my script, or i did some other mistake. On IRC cmouse tell, that removeflag was fixed in some early version (2.3.5 or so), but it doesn't work here. Please, how i can get it working? regards PS: please CC me, i am not subscribed -- Slavko https://www.slavino.sk/

Replacing antispam plugin with IMAPSieve not 100% correct?
by Marc 04 Oct '22

04 Oct '22

I think this page[1] is not correct If you configure this option: imapsieve_mailbox1_before = file:/usr/lib/dovecot/sieve/report-spam.sieve the file report-spam.svbin cannot be created because users cannot write there.
