Informational messages written to ~/.dovecot.sieve.log
by Gedalya 29 Apr '22

29 Apr '22

Hi, After adding "vnd.dovecot.debug" to the require list at the top of a sieve script, informational messages started appearing in ~/.dovecot.sieve.log, even when debug_log was not used. The script looks like this: require ["fileinto","imap4flags","reject","duplicate","vnd.dovecot.debug"]; # rule:[Duplicate] if duplicate :header "X-dd-hash" :last { debug_log "Duplicate message, discarding"; discard; } [ .. more rules .. ] Log lines: sieve: info: started log at 2022-04-28 23:49:43 -0400. info: msgid=<xxxxxxxxx>: stored mail into mailbox 'INBOX'. (no rule matched) sieve: info: started log at 2022-04-29 00:51:40 -0400. info: msgid=<xxxxxxxxx>: fileinto action: stored mail into mailbox 'Alerts'. I would expect / prefer that the log would be used only when debug_log was used. With too many log messages, the interesting ones would get rotated out sooner than desired.

Can I set a different certificate per listen port?
by Kees van Vloten 28 Apr '22

28 Apr '22

Hi all, I am trying to setup dovecot to listen to imaps on the local network and through haproxy from the internet. service imap-login { inet_listener imaps { port = 993 ssl = yes } inet_listener imaps_haproxy { haproxy = yes port = 10993 ssl = yes } } Obviously the dns-name on the internet connection (10993) is different than on the lan (993). In the docs (https://doc.dovecot.org/configuration_manual/dovecot_ssl_configuration/) I found multiple options, but unfortunately none of those have the option to distinguish per listen port. Is there a way to setup two different certificates for the two listeners? - Kees

Hello, I've set up a master user for migration purposes and doveadm auth tests succeed.

Heads-up: Exim 4.96 RC0 may break your Dovecot LDA delivery
by Kirill Miazine 25 Apr '22

25 Apr '22

Hi, all The just released RC0 for Exim 4.96 will break Dovecot LDA delivery as described on https://wiki.dovecot.org/LDA/Exim Here is the relevant ChangeLog entry: JH/25 Taint-check exec arguments for transport-initiated external processes. Previously, tainted values could be used. This affects "pipe", "lmtp" and "queryprogram" transport, transport-filter, and ETRN commands. The ${run} expansion is also affected: in "preexpand" mode no part of the command line may be tainted, in default mode the executable name may not be tainted. As of now I don't have a personal working solution to get untained data. I did try a small hack, but Exim was smart enough to see what I was doing. -- -- Kirill Miazine <km(a)krot.org>

doveadm pw usage

Hello when i want to assign a password to a user, I need to write the plain passwd to a text file then do: # doveadm pw -p input.txt {CRAM-MD5}77180880... it's not that convenient to write to a file first. does it support the format below? doveadm pw "plain password" providing the plain password as CL argument to generate a encrypted one. thank you ミユナ alice

auth between postfix and dovecot?
by ミユナ (alice) 25 Apr '22

25 Apr '22

hello experts, I have installed postfix and dovecot in the same machine. Their configure looks as: service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { mode = 0600 user = postfix group = postfix } unix_listener /var/spool/postfix/private/auth { mode = 0666 user = postfix group = postfix } auth_mechanisms = plain login !include auth-passwdfile.conf.ext my question is: when postfix talks to dovecot, does it require user's username/password for authentication? or this communication just goes without authentication? I asked this, b/c my webmail send mail from localhost has been going without authentication to postifx. so i am not sure if postfix talks to dovecot without requiring auth too. Thanks alice

Weird status... " noselect"... why ?

a list "" * gives me this * LIST (\HasChildren \UnMarked) "/" INBOX/2022-PERSONNEL/FOO2 * LIST (\HasNoChildren \UnMarked) "/" INBOX/2022-PERSONNEL/FOO2/test * LIST (\Noselect \HasChildren) "/" INBOX/2022-PERSONNEL/FOO2/test * LIST(\Noselect \HasNoChildren) "/" INBOX/2022-PERSONNEL/FOO2/test/Location As you can see there is " noselect " and with Thunderbird this is in grey.. Due to a bad manipulation. I wanted to create a subfolder and I wrote "FOO2/test" when FOO2 didn't exist yet Now " test" is grey and I cannot place anything inside.. I didn't see this at first sight and I've placed important emails in it, that it didin't synch... and which which seems to be lost :-( a Repair didn't work out How can I " revalidate " this folder ? without removing it ? ( hoping to get something in it ) Thanks

replication fails with "Error: sync: Unknown user in remote" but user shows up in doveadm user "*"
by Arnaud Abélard 22 Apr '22

22 Apr '22

Hello, I've been trying to replicate a production server (debian buster, dovecot 2.3.4.1). But I nothing is actually being replicated and for each attempted user the message "Error: sync: Unknown user in remote" is being logged. The ldap settings are actually the same on both server (source and destnation) and the "unknown user" is actually showing up in doveadm user "*" on the destination server. I had already replicated 2 servers and used the same settings. Am I missing something obvious here? Thanks, Arnaud -- Arnaud Abélard Responsable pôle Système et Stockage Service Infrastructures DSIN Université de Nantes -

disabling namespace in special-userdb on dovecot 2.2
by Marc 22 Apr '22

Currently I have such special-userdb file test:x:11111:22222:testaccount_descr:/home/users/testaccount:/bin/false:userdb_mail=mbox:~/mbox:INBOX=/home/users/testaccount/inbox:INDEX=/home/users/testaccount/index However I am still getting errors of a default configured namespace that still seems to be active. Is there a way to disable this namespace or reconfigure this in the userdb file? (When I was testing this on a dovecot 2.3 I did not run into this)

Hello, has there been any development on JMAP support in Dovecot? Also, I have noticed you planned to do some generic optimizations which could possibly make it easier to implement JMAP.

NFS Config vs Ceph / GlusterFS
by dovecot＠ptld.com 15 Apr '22

15 Apr '22

Do all of the configuration considerations pertaining to using NFS on https://doc.dovecot.org/configuration_manual/nfs/ equally apply to using something like Ceph / GlusterFS? And if people wouldn't mind chiming in with which (NFS, Ceph & GlusterFS) they feel is better for maildir mail storage on dedicated non-container servers? Which is better for robustness / stability? Which is better for speed / performance? Thank you.

Hi, I'm trying to enable TLS1.0 support for an old client. Per dovecot -n # 2.3.7.2 (3c910f64b): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.7.2 () # OS: Linux 5.4.0-107-generic x86_64 Ubuntu 20.04.4 LTS ext4 # Hostname: In 10-ssl.conf, I have set ssl_min_protocol = TLSv1 (It doesn't show in dovecot -n, I suspect because it's equal to default value?) I restarted dovecot with systemctl. Then, from another machine, openssl s_client -connect zeserver.com:993 -tls1 fails with this output: CONNECTED(00000003) 140166917489984:error:141E70BF:SSL routines:tls_construct_client_hello:no protocols available:../ssl/statem/statem_clnt.c:1112: --- no peer certificate available --- No client certificate CA names sent --- SSL handshake has read 0 bytes and written 7 bytes Verification: OK --- New, (NONE), Cipher is (NONE) Secure Renegotiation IS NOT supported Compression: NONE Expansion: NONE No ALPN negotiated Early data was not sent Verify return code: 0 (ok) --- The same command with -tls1_2 works as intended (certificate printing, imap prompt).

What google is turning off is "third-party apps or devices which ask you to sign in to your Google Account using only your username and password", i.e., using your google login password with "less secure" 3rd party apps. So, you need to set up, and configure your application to use, app passwords.

Dovecot and OAuth2 and gmail

Hi all, I'm not sure Dovecot has anything to do with this, but I'd rather ask and know for sure. I do the following: Gmail IMAP=>fetchmail=>procmail=>Dovecot IMAP Then, I view my Dovecot hosted email with Claws-Mail. I understand that on May 31, 2022, current methods to access Gmail IMAP will turn into pumpkins because of insistence on OAuth2. Do I need to do anything to Dovecot to get ready for this Mass Extinction Event? Do you think I'll need to dump fetchmail for something else?

Permissions and ownership on /dev/shm/dovecot
by doug 12 Apr '22

12 Apr '22

Hi, Environment: Dovecot 2.3.18 running on CentOS 7, mdbox, LDAP users I'm in the process of moving my mailboxes to NFS and moving with lock and index files in temp storage following instructions from https://doc.dovecot.org/configuration_manual/nfs. I set mail_location as: mail_location = mdbox:/mailstore/%u/mail:VOLATILEDIR=/dev/shm/dovecot/%u:LISTINDEX=/dev/shm/dovecot/%u/dovecot.list.index What I discovered is /dev/shm/dovecot is created by the initial user who accesses their mail from a client, and with permissions 700. This prevents subsequent users from creating their own index and lock files. # ls -l /dev/shm/dovecot total 0 drwx------ 2 mary users 60 Mar 25 10:00 mary Sample error message from maillog during mail delivery and from a dsync script.

As a hack, I added this to /usr/libexec/dovecot/prestartscript. ! [[ -d /dev/shm/dovecot ]] && mkdir /dev/shm/dovecot chown dovecot:users /dev/shm/dovecot chmod 770 /dev/shm/dovecot This solved the problem, but left me wondering if I missed something obvious or if I am setting myself up for a problem later on, like with a Dovecot version upgrade. I could run these commands at bootup out of rc.local or a systemd script rather than customizing a Dovecot provided script. Is there a appropriate way of doing this that I missed? TIA, Doug

Set up per user sieve rules

Hello! I am struggling to wrap my mind around how to set up sieve rules for my individual users on my mail server. I set up a global sieve script file at "/var/lib/dovecot/sieve/default.sieve” and that works great. My users maildirs are located at /mnt/volume1/mailserver/maildir/user. Do I need to create a sieve script file inside of that folder for sieve scripts to work on an individual basis? If so, what permissions will that script file need? Thanks in advance for your help!

Dovecot 2.3.13 virtual mailboxes subscription problem
by Slavko 10 Apr '22

10 Apr '22

Hi, by discussion on IRC channel is post details here. I am using virtual plugin in dovecot 2.3.13 and i have porblems with subsription to these virtual mailboxes. I can setup autosubscribe to them and it works as expected. I can SUBSCRIBE to them, dovecot returns OK and they are added in subscriptions file, but then they are not shown in LSUB output. I can UNSUBSCRIBE from subscribed virtual mailbox (dovecot returns OK), but it is not removed from subscriptions file and remains there... I bother with this for long time. I tried to setup mailboxes without UTF-8 chars, but that doesn't matter nad currently problematic mailbox has not any nonASCII char (Virtual.Dnes). I tried to define mailboxes in parent namespace too, doesn't help, nor defining only Virtual in parent namespace (with and without separator at end). Some evidence follows. The (my) subscriptions file (the Virtual.Dnes is at end): --------------------------------------------------------- V 2 <snip> Virtual Dnes --------------------------------------------------------- IMAP LIST (only Virtual namespace), as shown by dovecot's imap command: --------------------------------------------------------- * PREAUTH [CAPABILITY IMAP4rev1 SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS THREAD=ORDEREDSUBJECT MULTIAPPEND URL-PARTIAL CATENATE UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS BINARY MOVE SNIPPET=FUZZY PREVIEW=FUZZY STATUS=SIZE SAVEDATE LITERAL+ NOTIFY METADATA SPECIAL-USE QUOTA ACL RIGHTS=texk] Logged in as slavko(a)slavino.sk <snip> * LIST (\Noselect \HasChildren) "."

Verejn&AOk- * LIST (\HasNoChildren \UnMarked) "." Verejn&AOk-.Novinky . OK List completed (0.004 + 0.000 + 0.003 secs). --------------------------------------------------------- One can see that there are three virtual mailboxes, the Virtual.Dnes, the Virtual.Dôležité (encoded) and the Virtual.Prílohy (encoded too), including Virtual namespace. IMAP LSUB output (again only Virtual namespace): --------------------------------------------------------- * PREAUTH [CAPABILITY IMAP4rev1 SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS THREAD=ORDEREDSUBJECT MULTIAPPEND URL-PARTIAL CATENATE UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS BINARY MOVE SNIPPET=FUZZY PREVIEW=FUZZY STATUS=SIZE SAVEDATE LITERAL+ NOTIFY METADATA SPECIAL-USE QUOTA ACL RIGHTS=texk] Logged in as slavko(a)slavino.sk <snip> * LSUB () "."

What is the current state of High Availability Dovecot ?
by White, Daniel E. (GSFC-770.0)[NICS] 10 Apr '22

10 Apr '22

… without going to too much fuss ? Searching the Internet produces a lot of old results and many overly complicated results. My only complication is that I am using PostfixAdmin for mailbox management, and all the mailboxes are virtual. Thanks.

Unable to write *.sieve files while Dovecot is running
by Ralph Seichter 08 Apr '22

08 Apr '22

I noticed lately that I can no longer modify *.sieve files while Dovecot is running. Write operations appear not to be permitted anymore: $ echo >> example.sieve zsh: permission denied: example.sieve Text editors like vim cannot write either. Since I used to be able to modify Sieve source files on the fly, I am wondering if the behaviour I see nowadays is intentional? Doveconf reports the following versions: # 2.3.14.1 (9f0cfb6426): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.14 (1b5c82b2) # OS: Linux 5.17.1-gentoo-r1-x86_64 x86_64 Gentoo Base System release 2.7 -Ralph

Problem with initial sync on new mailbox in a replicated setup
by ppq＠tuta.io 07 Apr '22

07 Apr '22

Hello, I run a two-node replicated setup with director + dovecot and replication between the two nodes. The setup is a couple of years old and has been working properly until recently, so I suspect some type of regression. I'm having an issue with replication and merging of newly created mailboxes. Old mailboxes work properly. When creating a new mailbox, the two nodes will not replicate and sync the new mailbox. I have to manually "merge" the mailbox via a "doveadm sync -1f..." command, after which all works properly. This has not been the case in the past, so I'm trying to debug the issue. When syncing manually, I get the following error: ----------------------------- # doveadm -v sync -df -u 'testaccount(a)mydomain.ext' doveadm(testaccount(a)mydomain.ext)<38041><wl3tAQ5LTWKZlAAAxdOQ8Q>: Warning: Mailbox changes caused a desync. You may want to run dsync again: Remote lost mailbox GUID 6bfcbb2f92484d624b890000c5d390f1 (maybe it was just deleted?) ---------------------------- I have to sync once with a one-way merge using sync -1f and after the sync works properly. My setup is running Dovecot CE 2:2.3.18-4+debian11 from the dovecot.org repository installed on debian bullseye. The replicaiton is dove via TCP plaintext connection. Below I'm attaching some debug logs, for both sync -1f and sync -f. Is this a normal behavior or is this a bug ?

resend whole inbox to user
by Marc 07 Apr '22

07 Apr '22

I was wondering if there is some way to force an imap client to 're-download' all the messages from the inbox. I can remember in the 'old days' that when the connection was dropped during a pop download, the whole inbox was re-downloaded, resulting in quite a lot of duplicates. I am looking for such action.

macOS ManageSieve client?
by Gerben Wierda 07 Apr '22

07 Apr '22

I have a dovecot & dovecot-sieve running under MacPorts on my macOS ’server’. I do a very low tech maintenance on sieve, by using the cli on the server and edit sieve by hand for myself. I’d like to open this up to other users. How do people use this from their macOS clients? For this, the ManageSieve protocol exists and this is implemented by dovecot-sieve, but other than installing roundcube and offering a web-based mail client that also supports ManageSieve, is there another way? A ManageSieve client that directly runs on the macOS client and interfaces with dovecot-sieve on the server? After all, routing mail to different mailboxes better happens server-side so that all clients profit.

Support of "extlists" in sieve filters
by Marcin Bajer 04 Apr '22

04 Apr '22

Hi all, Don’t really know if this is sth. to post on this forum, but I tried to make a sieve filter which tags mails from my contacts by the category of the contact. Seems this feature is available in Protonmail: https://protonmail.com/support/knowledge-base/sieve-advanced-custom-filters/ require [“fileinto”, “extlists”]; Checks that the sender is in your personal address book if header :list “from” “:addrbook:personal?label=Family” { fileinto “Known”; } Would it be possible to implement such feature also in dovecot? BR, Marcin

Replication issues with 2.3.18 - Replication fails after xxx folders reached.
by Paul Kudla (SCOM.CA Internet) 02 Apr '22

02 Apr '22

please appreciate that i am trying to help .... after much testing i can now reporduce the replication issues at hand I am running on freebsd 12 & 13 stable (both test and production servers) sdram drives etc ... Basically replication works fine until reaching a folder quantity of ~ 256 or more to reproduce using doveadm i created folders like INBOX/folder-0 INBOX/folder-1 INBOX/folder-2 INBOX/folder-3 and so forth ...... I created 200 folders and they replicated ok on both servers I created another 200 (400 total) and the replicator got stuck and would not update the mbox on the alternate server anymore and is still updating 4 days later ? basically replicator goes so far and either hangs or more likely bails on an error that is not reported to the debug reporting ? however dsync will sync the two servers but only when run manually (ie all the folders will sync) I have two test servers avaliable if you need any kind of access - again here to help. [07:28:42] mail18.scom.ca [root:0] ~ # sync.status Queued 'sync' requests 0 Queued 'high' requests 6 Queued 'low' requests 0 Queued 'failed' requests 0 Queued 'full resync' requests 0 Waiting 'failed' requests 0 Total number of known users 255 username type status paul(a)scom.ca normal Waiting for dsync to finish keith(a)elirpa.com incremental Waiting for dsync to finish ed.hanna(a)dssmgmt.com incremental Waiting for dsync to finish ed(a)scom.ca incremental Waiting for dsync to finish nick(a)elirpa.com incremental Waiting for dsync to finish paul(a)paulkudla.net incremental Waiting for dsync to finish i have been going through the c code and it seems the replication gets requested ok replicator.db does get updated ok with the replicated request for the mbox in question. however i am still looking for the actual replicator function in the lib's that do the actual replication requests the number of folders & subfolders is defanately the issue - not the mbox pyhsical size as thought origionally. if someone can point me in the right direction, it seems either the replicator is not picking up on the number of folders to replicat properly or it has a hard set limit like 256 / 512 / 65535 etc and stops the replication request thereafter. I am mainly a machine code programmer from the 80's and have concentrated on python as of late, 'c' i am starting to go through just to give you a background on my talents. It took 2 months to finger this out. this issue also seems to be indirectly causing the duplicate messages supression not to work as well. python programming to reproduce issue (loops are for last run started @ 200 - fyi) : # cat mbox.gen #!/usr/local/bin/python2 import os,sys from lib import * user = 'paul(a)paulkudla.net' """ for count in range (0,600) : box = 'INBOX/folder-%s' %count print count command = '/usr/local/bin/doveadm mailbox create -s -u %s %s' %(user,box) print command a = commands.getoutput(command) print a """ for count in range (0,600) : box = 'INBOX/folder-0/sub-%' %count print count command = '/usr/local/bin/doveadm mailbox create -s -u %s %s' %(user,box) print command a = commands.getoutput(command) print a #sys.exit()

falsely log "auth: unknown user" when multiple userdb
by Anthony Panko 01 Apr '22

01 Apr '22

Hello, When there is a multiple userdb to look for user, Dovecot log «auth: unknown user» when the first userdb search failed. Then Dovecot successfully search user in the second userdb and things works. But "auth: unknown user" event left in a logs. Logs look like this: Apr 1 12:38:48 mail dovecot[75384]: lmtp(75397): Connect from 127.0.5.1 Apr 1 12:38:48 mail dovecot[75384]: auth: ldap(order(a)XXX,127.0.5.1): unknown user Apr 1 12:38:48 mail dovecot[75384]: lmtp(order)<75397><D8m2HCjIRmKFJgEAABdyCg>: msgid=<157609214.20220331172309@YYY>: saved mail to INBOX Debug show failed search in the first userdb and successfull search in the second userdb.

Dovecot Submission - rate limiting
by itanguy＠univ-brest.fr 31 Mar '22

31 Mar '22

Hello, is there any way to rate limit submission mail (counting per user) when using Dovecot/Submission (no Postfix)? Using a milter seems impossible. Using Dovecot Events seems "too" global (not per users discrimination). Maybe rate-limiting has to be external and then include in the pass_db query ? Thank your for any hints. Ismaël Tanguy

Simplifying Support of Virtual and System Users
by Mark Olbert 29 Mar '22

29 Mar '22

Apologies if this has already been raised here (which I suspect it has 😊). I tried to raise it as an issue over on github but issues are not enabled for the repository. The support for mixing virtual users, with fully-qualified email addresses, and system users could be simpler. Assuming it doesn’t mess up other stuff in the code base, of course 😊. The problem appears to be that the PAM passwd module requires just user names without a domain (which makes sense given that they’re system users) but does not, so far as I can see, support the username_format argument. In my setup, the default structure of 10-auth.conf demonstrates this: auth_username_format = %n That means all username arguments lack the domain part…which complicates using fully-qualified ones for virtual users. I realize I could assign arbitrary unique names to the virtual accounts in the lookup file. But that complicates administering the system, so I want to be able to include the domain for virtual users. After about five hair-pulling hours of wrestling with the configuration I stumbled across an answer utilizing conditionals<https://serverfault.com/questions/260488/dovecot-user-lookup-fails-when-usi…> on ServerFault. It works fine. But being able to pass a username_format parameter to the PAM module (which I tried, but it was rejected) would be a lot simpler, and a lot more intuitive. - Mark

Private \seen flags lost during message move for other users
by Cube . 28 Mar '22

28 Mar '22

Hello, I have a shared mailbox set up with a private index: maildir:/var/mail/public:INDEXPVT=~/Maildir/public Per user \Seen flags are working fine until one user moves a message into another folder/sub-mailbox. For that user doing the move the message remains \Seen however for other users who have already seen the message the flag is lost and it appears unread in the new location. If the message is moved back it still appears unread to the other user even if had been read in that folder/sub-mailbox in the past. Is there anyway to retain per user \Seen that follows the message when its moved? Thank you.

dovecot replication on dovecot v 2.3.8
by Stephane Magnier 27 Mar '22

27 Mar '22

Hi, I am trying using a replication. Here is my config : 10-mail.conf. Before going " on real life " I try to make a very basic example... but without any success :-( bad start I took the config example on dovecot wiki The idea is to replicate the user: "user1" on a different server IP 177.28.1.120 at the location /home/SERVER/test and to get at the end the folder "/home/SERVER/test/user1" On the top, I wish to replication with the user / group : vmail. For the transfer, I use the root login on the backup server to avoid other rights problems at the moment 2) how to synchronized specific users ? apparently it's trying to sync other things.. :-) # mbox_very_dirty_syncs = yes mail_plugins=$mail_plugins quota notify replication service replicator { process_min_avail = 1 } dsync_remote_cmd = ssh -l root 177.28.1.120 doveadm dsync-server -u user1 plugin { mail_replica =remote:root@177.28.1.120:/home/SERVER/test/ } service aggregator { fifo_listener replication-notify-fifo { user = vmail } unix_listener replication-notify { user = vmail } } service replicator { unix_listener replicator-doveadm { mode = 0600 user = vmail } } replication_max_conns = 10 But apparently nothing is happening....

log failed plaintext password for specific user only
by mj 25 Mar '22

25 Mar '22

Hi, We are logging failed authentication attempts, with the attempted password as auth_verbose_passwords=sha1 The question: is it possible to configure auth_verbose_passwords=plain for a specific user only? Turning it on globally would be too much sensitive information for the purpose. Reason: We are currently observing a high number of failed authentications for a specific user, coming from *many* diffirent IPs across the globe, with most IPs only trying once or twice, making this difficult to block. The number of failed authentications cause this account to regularly become blocked in AD. We would like to know if they are trying older actual passwords from the user, or if it's just dictionary attack. Thanks!

Setting imap-login process_limit when service_count>1
by Joseph Tam 25 Mar '22

25 Mar '22

More of my users are accessing mail remotely, which probably explained why I started seeing Mar 18 05:50:34 dovecot: master: Warning: service(imap-login): process_limit (2) reached, client connections are being dropped I played around with increasing limits, but made the mistake of setting service_count to a value other than 0 and 1. service imap-login { client_limit = 1024 service_count = 10240 process_min_avail = 2 process_limit = 8 } Doubling and redoubling process_limit and increasing service_count didn't prevent IMAP from eventually grinding to a halt because process_limit was reached. Mar 18 12:36:12 dovecot: master: Warning: service(imap-login): process_limit (4) reached, client connections are being dropped Mar 18 20:39:48 viol dovecot: master: Warning: service(imap-login): process_limit (8) reached, client connections are being dropped Observing the way imap-login processes spawn and retain file descriptors, I finally understood the subtlety of [1], which explains that imap-login will not exit despite reaching service_count if one SSL connection is still open. With many long-lived client connections, the asymptotic behaviour is that the total #clients plateaus, but get spread out over many imap-login processes, with many lingering on to hold a few SSL connections. For service_count>1, process_limit should be set to a large fraction of peak simultaneous clients (i.e. the same value used when service_count=1), otherwise there is a high likelihood of running into process_limit and game over. Given this behaviour, there doesn't seem much sense in setting service_count to anything but 0 (unlimited => performance mode) or 1 (security mode). Setting to other values supposedly limit memory leaks, but if a single persistent SSL client can hold up an imap-login process from exiting and releasing memory, it seems to negate this purpose. Anyways, maybe [1] can mention this so others don't fall into the same pit I did. References [1] https://doc.dovecot.org/admin_manual/login_processes/ Joseph Tam <jtam.home(a)gmail.com>

ok replication does not work

would someone please send me the standard that you are working towards (rfc stuff) in the mean time a bad email or folder or both are simply causing replication not to work no there is no logging of any kind of an error i would appreciate the info as i will start ripping down the c code to fix this doveadm / replication (seems to be seperate ???) remote , tcp tcps nothing works your co operation on this matter would be appreciated i dumped the 5 accounts listed below started from scratch and it just simply DOES NOT WORK all account replicate except for # sync.status Queued 'sync' requests 0 Queued 'high' requests 5 Queued 'low' requests 0 Queued 'failed' requests 0 Queued 'full resync' requests 0 Waiting 'failed' requests 0 Total number of known users 255 username type status paul(a)scom.ca incremental Waiting for dsync to finish nick(a)elirpa.com incremental Waiting for dsync to finish keith(a)elirpa.com incremental Waiting for dsync to finish ed.hanna(a)dssmgmt.com incremental Waiting for dsync to finish ed(a)scom.ca incremental Waiting for dsync to finish always the same five accounts and always they choke without any info i am forced to do a sync every five minutes (ten minute intevals) to keep the servers in sync. someone please give me a standard to work with otherwise the hacks that i do will be exactly that a hack???

imap_metadata plugin panic
by Elisamuel Resto 23 Mar '22

23 Mar '22

Hello, This may be covered somewhere but recently I enabled the metadata plugin to work with sieve as part of some updates I did a while back and I hadn't checked my logs for any issues with it and so far they're not completely taking my system down. Right now, upon trying to delete a folder I noticed the following in my logs... what am I missing? I see the broken SQL query, but I don't know enough about the dict system or the metadata plugin to know how to add the missing information or fix it otherwise. Regards, Elisamuel Resto Nov 15 12:19:19 wyvern dovecot[461]: dict(51438): Panic: lib-sql: Too many bind args (2) for statement: SELECT meta_key FROM metadata WHERE meta_key LIKE AND username = ?

Disconnected: Shutting down (disconnected while authenticating) :: after mysql restart :: bug?
by rudolf＠padaru.de 17 Mar '22

17 Mar '22

Good morning list, i looking for a while for a solution above problem. We use dovecot 2.3.7.2 (3c910f64b) (Ubuntu 20.04) and 2.3.13 (89f716dc2) (Ubuntu 18.04) . Often we have the problem, that the authentication (dovecot <-> mysql) dont work after an mysql restart. Unfortunately i cant reproduce this problem, if i restart the mysql-server the authentication work when the database is up again. If we have this problem it is enough to reload the dovecot. So that the auth-worker will reconnect and everything is fine again. I have tried to encircle the problem with verbose auth-logging a wile ago but i only see timeouts from the auth-worker while mysql is running But this is not the solution für the problem. Is there an option i can set to force the auth-worker to reconnect? Maybe an timeout or something else? Or is there an value set to high in my conf? Somethin like the idle_kill from anvil service? Or is it simply a bug? doveconf output: auth_anonymous_username = anonymous auth_cache_negative_ttl = 1 hours auth_cache_size = 0 auth_cache_ttl = 1 hours auth_cache_verify_password_with_worker = no

Finding Users Over Quota
by dovecot＠ptld.com 17 Mar '22

17 Mar '22

Using doveadm quota will let you see if a specific user is over quota. Is there a way to have dovecot tell you which users are currently over quota? Is the quota_clone plugin a way to save user quota to dict like how last_login saves to dict? The documentation for quota_clone is MIA.

SIS and tracing the origin of an attachment
by doug 16 Mar '22

16 Mar '22

Hi All, I'm trying to trace an attachment within an SIS subdirectory to the email message(s) that link to it. I say messages because I'm also using dovecot dedup. My understanding is the linked file name is the hash value of the attachments contents concatenated with the GUID of the email message. I have had marginal success with a message I created myself. Example: I generated an email with two attachments. Here are the links in my attachment directory. ./26/c5/26c5c540d41779d83d2f5388041d05c67d720d9a-73eca8051acd276272310000f2bc99a3 ./65/cd/65cd73112a489ef07f17ed5740aa60358e2dd3fb-74eca8051acd276272310000f2bc99a3 In my sent folder the actual GUID of the message is 75eca8051acd276272310000f2bc99a3. So the GUID of the attachment is based on the GUID of the message, but not exact. The second hex byte seems to be decremented as an offset of the attachment index from the GUID of the message. At least in my one example. # doveadm dump /mailstore/doug/mail/mailboxes/Sent/dbox-Mails/dovecot.index | grep guid | tail -1 - guid: 75eca8051acd276272310000f2bc99a3 With that actual GUID I can find the message with a search: # doveadm search -u doug mailbox Sent guid 75eca8051acd276272310000f2bc99a3 doug e5711f1cf2c9294f71090000059b96e4 53526 Now let's try to track down another email when only the HASH-GUID value is known. Here is one randomly picked. ./00/a2/00a2d5de3e41053d59bd10084826bbe094aa1c59-57857b09d1a327627e260000f2bc99a3 # doveadm search -A mailbox '*' guid 57857b09d1a327627e260000f2bc99a3 # doveadm search -A mailbox '*' guid 58857b09d1a327627e260000f2bc99a3 # doveadm search -A mailbox '*' guid 59857b09d1a327627e260000f2bc99a3 I repeated this incrementing and decrementing from 5085... through 5f85... and never located the message. This seems like it should be trivial but I've been struggling with it for days. The GUID isn't random, there must be a way to track the attachment back. What am I missing? And for those wondering why, our virus scanner flagged a number of attachments, some with several links, and I want ask the users to delete the offending messages so I can purge them from the server. If I can find the emails I can give them the mail folder, date/time, and subject of the message. -- Doug

invalid lz4 chunk size??
by Joachim Lindenberg 16 Mar '22

16 Mar '22

Hello, when accessing one mailbox via ActiveSync / SoGo / Dovecot I get the following error repeatedly in dovecot log: imap(somemailbox(a)example.org)<1579><***>: Error: Mailbox Sent: UID=1553: read(compress()) failed: read() failed: lz4.read(): invalid lz4 chunk size: 1601505441 at 16842752 (read reason=) I can still access the mailbox via IMAP though. What can I do to resolve the issue? Thanks, Joachim

sieve-filter not respecting :create flag of fileinto
by David Arroyo 16 Mar '22

16 Mar '22

Hello, I recently significantly modified my sieve rules for filing mailing list posts in my Fastmail inbox. The rules contain a few rules that file mail like so: fileinto :create ml.${5}${4}{$3}{$2}{$1}; # reversed list-id The rules work as expected on delivery to fastmail. Because these rules only run on delivery, and the new folder layout is different from my existing one, I want to apply the rules to my existing mail. I thought dovecot's `sieve-filter` command, together with the `imapc` storage backend, would be a good way to do that, so I moved some existing mail into a folder, `sieve-test`, and ran the following: sieve-filter -x '+editheader +mailbox' -W -e rules.sieve sieve-test However, what I see is that sieve-filter fails when the new directory does not exist. Here is some example (redacted) output: Info: imapc(imap.fastmail.com:993): Connected to x.x.x.x:993 (local x.x.x.x) error: msgid=<xxx>: fileinto action: failed to store into mailbox 'ml.gnu.guix-devel': Mailbox does not exist. sieve-filter(me): Info: sieve: msgid=<xxx>: left message in mailbox 'sieve-test' error: sieve script execution failed for this message; message left in source mailbox. sieve-filter(me): Info: sieve: msgid=<yyy>: fileinto action: stored mail into mailbox 'ml.9fans.9fans' My config looks like this: protocols = none mail_location = imapc: namespace { inbox = yes separator = . } imapc_host = imap.fastmail.com imapc_port = 993 imapc_ssl = imaps imapc_user = $username If this is a bug in sieve-filter I'd be happy to try and fix it, but I'm reaching out here first to see if this is expected behavior or a misconfiguration on my part. Thanks for any help, David

mdbox_rotate_size recommendation / performance
by Lucas Rolff 15 Mar '22

15 Mar '22

Hi guys, When using mdbox under Dovecot, the mdbox_rotate_size setting defaults to 10 megabyte - from a performance point of view if using spinning drives does this matter whether one goes for e.g. 2MB versus 10MB, especially in the combination with compression. Does anyone have any performance data regarding it’s size, and what’s a decent trade-off between limiting IOPS required by the drive versus the sequential read/write speeds. Any pointers would be awesome! Thanks in advance

AntiVirus in Maildir
by Masakazu Hirose 15 Mar '22

15 Mar '22

Hi all, I run a mail server on Maildir. Does Dovecot work correctly if I delete the mail files stored in Maildir? Do I need to run the doveadm command? I want to run a virus scan on Maildir. When a virus is detected, the mail file is deleted without notifying Dovecot. I assumed this was incorrect behavior for Dovecot. Please help me when someone has time. Thanks, Masa

allow_nets equivalent for all users?
by Bryan K. Walton 14 Mar '22

14 Mar '22

Hi, It is my understanding that allow_nets is a field that gets used in a password database, and therefore is a per-user setting. Is there an equivalent method for defining allowed network(s) for ALL users? In other words, a single setting that applies to every user? Thanks, Bryan

Possible bug interaction between Dovecot and Thunderbird 98/99 email client
by Arthur Koziol 11 Mar '22

11 Mar '22

Hi Dovecot devs, My name is Arthur. I'm a volunteer with Mozilla and am working with a user who's having some odd issues with his Thunderbird email client. I'm reaching out to you folks because he's using an at-home IMAP setup with Dovecot. It's not 100% clear if his setup is polling his GMail accounts and then pulling everything to his Dovecot setup but if there's any interesting in jumping into the bug we're trying to help this user with, feel free to browse the bug at https://bugzilla.mozilla.org/show_bug.cgi?id=1726319 I asked the user if he's reached out to the Dovecot devs yet but he's not replied. We're not sure if this is a Dovecot / setup issue, a Thunderbird issue or something in between but we could use some other eyes and ideas of what to check for this user if you guys have a couple seconds to take a look. Thanks for reading. best, Arthur

Can't create viable password hashes
by David Griffith 11 Mar '22

11 Mar '22

I recently discovered that I can no longer create viable password hashes for use in /etc/dovecot/dovecot.passwd. So far, I've been using the following command done by root: doveadm_cmd pw -s SHA512-CRYPT -u joe -p mypassword This creates something that looks legit, but dovecot won't accept it. I've been using my own solution for allowing users to change their dovecot passwords (https://gitlab.com/DavidGriffith/dovepasswd) and this is how it generates the hashes. Is there a better way of going about this? -- David Griffith dave(a)661.org A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting.

Replicator Issues on Large Mail Boxes

Pigeonhole Sieve: Vacation Extension issue
by Zakaria 05 Mar '22

05 Mar '22

Hi there, I wondered if there is any one who can help me out on this issue. I tried to setup the vacation extension, and it works fine if the Return-Path header and Envelope-From field in Received wasn’t rewritten and contains the actual sender email address which the vacation extension will retrieve from and reply to. Given, I’ve rewritten both headers, to modify TLS connection mailed-by address and I had to revert back to get the vacation extension working, I wondered if there is anyone know how to modify the Sieve settings in Dovecot config for LMTP/LDA and Sieve, or Sieve script rules to retrieve sender email address from From header or any other specific header? If it's not possible, it would be so good if its implemented, it doesn’t seem to be a hard task, so please log this as a feature request. With thanks. Zakaria. Btw, all my prayers and solidarity I send out to Ukraine, Russia and the rest of Europe, and the world, and the sick from this and COVID and alike. We should value one another, Seriously, Putin must urgently stop giving to who want destruction and harm in Europe and manipulating behind the scene such devil affair and leading to this very sickening and unacceptable horror. Palestine deserve justice than preoccupying the world with creating more injustices.

doveadm quota get hangs for 60 seconds (some analysis done)
by jaroslav＠thinline.cz 05 Mar '22

05 Mar '22

Hello, I encountered somewhat strange behaviour when running doveadm quota get with wildcard username (all usernames are in user@domain format): doveadm -f pager quota get -u *(a)example.domain The command hangs for 60 seconds before returning its result. I tried to dig into the issue a bit using strace and found out that there seems to be some kind of communication mismatch between Dovecot processes. Here is what I found - sorry for the wall of text, strace outputs tend to be large, I tried to reduce them as much as possible. I also tried to draw some conclusions below. This is from strace in the doveadm process, it connects to auth-userdb and requests list of users 1646473083.263021 connect(10, {sa_family=AF_UNIX, sun_path="/run/dovecot/auth-userdb"}, 110) = 0 1646473083.263627 write(10, "VERSION\t1\t0\nLIST\t1\tuser=*(a)example.domain\n", 47) = 47 1646473083.263807 read(10, "VERSION\t1\t1\nSPID\t30012\n", 8192) = 23 1646473084.188212 read(10, "LIST\t1\tuser1@notthat.domain\nLIST\t1\tuser2@another.domain\nLIST\t1\tuser3@also.not\nLIST\t1\t.... This list goes on, the server has over 10000 user accounts. (As a side note, this behaviour struck me as strange - I would expect that the result would be filtered by the server side of the connection, only listing users that match the requested wildcard. I don't know anything about Dovecot internals though, so this might be perfectly normal.) At some point the returned data contain users doveadm is interested in (ie. users that match the wildcard) and requests their information from other Dovecot services, this is an excerpt for a dict service: 1646473084.224608 connect(13, {sa_family=AF_UNIX, sun_path="/run/dovecot/dict"}, 110) = 0 1646473084.225617 write(13, "H2\t2\t0\trelevantuser(a)example.domain\tsqldomainquota\n", 50) = 50 No data are read from FD 10 during this time. When all users are queried, reading from FD 10 resumes 1646473084.274405 read(10, "ifth.domain\nLIST\t1\tuser987(a)domain.six\nLIST\t1\t... At this point though, the process gets stuck: 1646473084.274514 epoll_wait(11, [], 1, 0) = 0 1646473084.274555 read(10, 0x5620076d79dd, 6035) = -1 EAGAIN (Resource temporarily unavailable) 1646473084.274601 epoll_wait(11, [{EPOLLIN, {u32=124338208, u64=94695563280416}}], 1, 155000) = 1 It resumes after 60 seconds, reads some more users and then receives string "DONE" 1646473144.287149 read(10, "LIST\t1\tuser456@domain.seven\nLIST\t1\tuser123@domain.e8\nLIST\t1\tuser7865@dom.nine\n", 6035) = 99 1646473144.287149 read(10, "LIST\t1\t ... ", 5936) = 82 ... 1646473144.294373 epoll_wait(11, [{EPOLLIN, {u32=124338208, u64=94695563280416}}], 1, 155000) = 1 1646473144.307846 read(10, "DONE\t1\t\n", 1611) = 8 Note that at this point the read syscall is no longer trucated. As opposed to reads above, which amounted to 8kB blocks, these are reading few addresses at a time. After the "DONE" string is received, there is no more communication with other Dovecot processes, doveadm prints out results to the console and terminates. Next I investigated the auth process. 1646473083.263121 accept(11, {sa_family=AF_UNIX}, [28->2]) = 23 1646473083.263181 getsockname(23, {sa_family=AF_UNIX, sun_path="/run/dovecot/auth-userdb"}, [28->27]) = 0 1646473083.263690 read(23, "VERSION\t1\t0\nLIST\t1\tuser=*(a)example.domain\n", 1024) = 47 1646473083.263939 connect(24, {sa_family=AF_UNIX, sun_path="auth-worker"}, 110) = 0 1646473083.264228 write(24, "VERSION\tauth-worker\t1\t0\nDBHASH\t1234567890abcdef1234567890abcdef\tfedcba0987654321fedcba0987654321\n", 97) = 97 1646473083.264271 writev(24, [{iov_base="1\t", iov_len=2}, {iov_base="LIST\t1\tuser=*(a)example.domain\tservice=\toriginal-username", iov_len=61}, {iov_base="\n", iov_len=1}], 3) = 64 1646473084.187567 read(24, "1\t*\tuser1(a)notthat.domain\n1\t*\t... 1646473084.187977 write(23, "LIST\t1\tuser1(a)notthat.domain\nLIST\t1\t Reads and writes alternate until these syscalls: 1646473084.238938 read(24, " ... \n1\tOK\n", 8167) = 5354 1646473084.239108 write(23, "LIST\t1\t ... , 51224) = -1 EAGAIN (Resource temporarily unavailable) 1646473084.239536 write(23, "LIST\t1\t ... , 51224) = -1 EAGAIN (Resource temporarily unavailable) From the timing this looks like a kernel buffer for the connection is filled because the other side is not reading the data. This matches strace from doveadm which is at this point reading information about quotas from dict service (timestamp 1646473084.225617.) Auth process seems to react to this by putting the FD on epoll list and then it goes to handle other connections. FD 24 is removed from the epoll list at the same time: 1646473084.239926 epoll_ctl(14, EPOLL_CTL_ADD, 23, {EPOLLOUT|EPOLLERR|EPOLLHUP, {u32=109861328, u64=94566699784656}}) = 0 1646473084.239980 epoll_ctl(14, EPOLL_CTL_DEL, 24, 0x7ffca3a9ae2c) = 0 FD 23 becomes writable relatively quickly, pending data is written to it and read from FD 24 is attempted with no data available: 1646473084.270224 epoll_ctl(14, EPOLL_CTL_DEL, 23, 0x7ffca3a9ae5c) = 0 1646473084.270271 write(23, "LIST\t1\t ... , 51224) = 51224 1646473084.270620 epoll_ctl(14, EPOLL_CTL_ADD, 24, {EPOLLIN|EPOLLPRI|EPOLLERR|EPOLLHUP, {u32=109860944, u64=94566699784272}}) = 0 1646473084.270712 read(24, 0x5602069198e3, 2813) = -1 EAGAIN (Resource temporarily unavailable) Again, nothing else happens for 60 seconds until FD 24 signals what I presume is a connection close attempt. Note that there was no data read from FD 24 but when the "SHUTDOWN" string arrives from it, auth process starts writing items to FD 23, one by one. 1646473144.286936 read(24, "SHUTDOWN\n", 2813) = 9 1646473144.287003 write(23, "LIST\t1\tuser456(a)domain.seven\n", 29) = 29 1646473144.287059 write(23, "LIST\t1\tuser123(a)domain.e8\n", 31) = 31 1646473144.287103 write(23, "LIST\t1\tuser7865(a)dom.nine\n", 39) = 39 There are multiple user databases, I assume the following is a lookup from the others: 1646473144.294256 writev(24, [{iov_base="2\t", iov_len=2}, {iov_base="LIST\t2\tuser=*(a)example.domain\tservice=\toriginal-username", iov_len=61}, {iov_base="\n", iov_len=1}], 3) = 64 1646473144.294379 read(24, 0x5602069198ec, 2804) = -1 EAGAIN (Resource temporarily unavailable) 1646473144.300490 read(24, "2\tOK\n", 2804) = 5 1646473144.300556 writev(24, [{iov_base="3\t", iov_len=2}, {iov_base="LIST\t3\tuser=*(a)example.domain\tservice=\toriginal-username", iov_len=61}, {iov_base="\n", iov_len=1}], 3) = 64 1646473144.300653 read(24, 0x5602069198f1, 2799) = -1 EAGAIN (Resource temporarily unavailable) 1646473144.307687 read(24, "3\tOK\n", 2799) = 5 1646473144.307751 write(23, "DONE\t1\t\n", 8) = 8 1646473144.307944 close(24) = 0 1646473144.308092 read(23, "", 977) = 0 1646473144.308185 close(23) = 0 I also looked into the auth-userdb (auth -w) service, it seems to mirror what happens in the auth process: [pid 22387] 1646473083.407660 accept(7, <unfinished ...> [pid 22387] 1646473083.407767 <... accept resumed>{sa_family=AF_UNIX}, [28->2]) = 17 [pid 22387] 1646473084.187096 write(17, "1\t*\tuser1(a)notthat.domain\n1\t*\t [pid 22387] 1646473084.233120 write(17, "1\tOK\n", 5 <unfinished ...> [pid 22387] 1646473084.233577 epoll_ctl(9, EPOLL_CTL_ADD, 17, {EPOLLIN|EPOLLPRI|EPOLLERR|EPOLLHUP, {u32=659542480, u64=94356796068304}} <unfinished ...> [pid 22387] 1646473084.234006 read(17, <unfinished ...> [pid 22387] 1646473084.234254 <... read resumed>0x55d12753b7d1, 8031) = -1 EAGAIN (Resource temporarily unavailable) And after 60 seconds: [pid 22387] 1646473144.286843 write(17, "SHUTDOWN\n", 9 <unfinished ...> At which point the other two requests come in and are replied to. As I said above, I don't know anything about Dovecot internals but from I can gather from these outputs, all data are exchanged correctly and nothing gets stuck reading them from a permanent storage or alike. This bug doesn't manifest every time but seems to be fairly deterministic in that it always triggers for some domains but not for others. From what I've noticed, this affected domain receives all its users in single 8k read in the doveadm process, which in turns triggers (relatively) lengthy lookups and forces the auth process to put more writes on hold (at timestamp 1646473084.239108) Is it possible that when this happens, the "OK" string received from auth-userdb process (timestamp 1646473084.238938) is overlooked and auth process is waiting for more data from auth-userdb while auth-userdb waits for another request? The server itself runs Dovecot 1:2.3.13+dfsg1-2 from Debian repository on amd64. Output from dovecot --version is 2.3.13 (89f716dc2). As far as I can see, nothing indicates this is a performance problem related to insufficient hardware - server runs at 25% CPU utilization average, Pressure Stall Information reports average of 0.5% for CPU, 1% for I/O. System memory used is 10 out of 64GB. As far as I can see, no Dovecot process becomes CPU-bound when doveadm is running. I tried some web search but found nothing related to this. For our purposes, this issue has a relatively simple workaround - using doveadm quota get on specific usernames instead of the wildcard one. Since this might be an issue with a relatively easy fix for someone who knows where to look, I decided to post this bug report anyway. If needed, I should be able to test patches that apply cleanly to Debian sources and compile with dpkg-buildpackage. Thanks

Dupliate-ish email search?
by ＠lbutlr 04 Mar '22

04 Mar '22

I'm mulling over writing some code to find emails in a maildir that are duplicates, ish. That is to say that sometimes the same message doesn't quite show up as an exact match. Like some ad company may send you three identical messages, except they aren't actually EXACTLY identical, the message-IDs are different, and may the to address quoted part is different, so normal duplicate finders fail to find them. Before I start, is this a solved problem? -- I thought that they were angels, but to my surprise, we climbed aboard their starship, we headed for the skies.

Issue in 2.3.18 with fts_header_excludes/includes
by Alessio Cecchi 03 Mar '22

03 Mar '22

Hi, I'm still doing some test with fts-flatcurve, after updating to 2.3.18 I enabled: fts_header_excludes = * fts_header_includes = From To Cc Bcc Subject Message-ID but when I try to re-index all messages with FTS flatcurve the fts-flatcurve/ folder inside the Maildir/ become huge. Taking for example a Maildir with cur folder of 1.1G the related fts-flatcurve folder passed from 140M to 2.2G. After remove fts_header_excludes/includes config options, and re-index all messages, the fts-flatcurve/ size return to normal size. Is an issue? Thanks -- Alessio Cecchi Postmaster @http://www.qboxmail.it https://www.linkedin.com/in/alessice

Does disabling POP3 just mean removing it from the `protocols` list?
by Sean McBride 02 Mar '22

02 Mar '22

Hi all, Hopefully a simple question. If I want to disable POP3 support (because everyone is using IMAP anyway), it is just a matter of removing `pop3` from the `protocols` setting in dovecot.conf? Are there side effects or other considerations I should be aware of? Thanks, Sean

multiple doveadm ports?
by Joachim Lindenberg 02 Mar '22

02 Mar '22

Hello, I am trying to add another doveadm listener but am struggling with that. The primary reason is that I want to enable replication between two systems and want the replication to be encrypted using TLS. However there are also other doveadm clients locally that are not using TLS and I don´t want to touch all of them. I tried to define something like service doveadm { inet_listener { port = 2425 } inet_listener { port = 2426 ssl = true } } But didn´t get that to work. Is that not possible? I also tried service doveadm { inet_listener { port = 2425 } inet_listener http { port = 2426 ssl = yes } } but then I failed with plugin { mail_replica = https:dove2.example.com:2426 } Can someone please share what is supported and what not, or any pointer to documentation that does? Thanks a lot! Regards, Joachim

Apple Mail behaviour: can not create sub-folders
by Joseph Tam 02 Mar '22

02 Mar '22

One of my Apple Mail users recently complained his mail reader couldn't create sub-folders -- he could only create top-level folders. Playing around with this, I discovered that I could create folders ( as opposed to mialboxes) *if* I specified mailbox name with a trailing slash. Has anyone come across this? Is this related to https://doc.dovecot.org/configuration_manual/mail_location/mbox/mboxchildfo… ? Joseph Tam <jtam.home(a)gmail.com>

Custom Authentication Method
by Matthew R 01 Mar '22

01 Mar '22

Hi guys, we're using Dovecot/Postfix here for our mail system. I'd like to switch the `passdb` authentication on Dovecot from PAM over to a custom implementation. We'd prefer to have some sort of script check the password with an external IAM provider via HTTP. Is there any way we can accomplish this? The idea is to have Dovecot somehow call a script or send a username/password to some service, which checks the username/password against the identity provider and returns a "yes/no" back to Dovecot. `checkpassword` seems like it may work but I see no documentation on its API.

Ok I am running two dovecot servers and feel pretty close to getting things resolved config wise there are however 2 or 3 issues that all seem to be related i have enclosed FULL config files for both mail18.scom.ca & mail19.scom.ca I have a private network that is used for the replication (10.221.0.0/24) - port 12345 is blocked by pf firewall from outside. I am running freebsd 12.1 and built one server and then raid copied it to the second (mail19) so all the ports / builds etc are identical I did start with dovecot-2.3.14 but pigeonhole would not build on freebsd (thanks for that advice / reply )until upgrade to dovecot-2.3.18 dovecot-2.3.18 was built and installed on both servers along with a good build (freebsd build error was fixed after upgrading) dovecot-2.3-pigeonhole-0.5.18 please note that the second mailserver (mail19) is on an nfs share dedicated to the server (i am awaiting sdram drives to replace this issue) but since i am getting errors on both servers i feel nfs share is not the issue (and yes i enabled dlock) mail18 is on normal sdram drives (more of an fyi as i dont think this is the issue) neither mail server is connected to the other in any kind of a shared way - other then replication postfix should be delivering via : pipe -n dovecot -t unix flags=DRhu user=vmail:vmail argv=/usr/local/libexec/dovecot/deliver -f ${sender} -d ${recipient} Replication only works properly at startup (ie the mail boxes do sync), afterwhich nothing seems to trigger the differences between the servers to update (notify i believe) manually running : [05:04:46] mail18.scom.ca [root:0] /usr/local/etc/dovecot # doveadm sync -u paul(a)scom.ca remote:10.221.0.19 & [05:21:18] mail19.scom.ca [root:0] /usr/local/etc/dovecot # doveadm sync -u paul(a)scom.ca remote:10.221.0.18 does seem to work but with mixed results. I also included postfix main.cf & master.cf as well as some googling has indicated the file locking may be on the postfix side ?? Also more then happy to donate just can not figure out how ??? so that being said : General logging errors are as follows ?

This feature is off by default. # # The right-hand side of the lookup tables is conveniently ignored. # In the left-hand side, specify an @domain.tld wild-card, or specify # a user(a)domain.tld address. # #relay_recipient_maps = hash:/usr/local/etc/postfix/relay_recipients # INPUT RATE CONTROL # # The in_flow_delay configuration parameter implements mail input # flow control. This feature is turned on by default, although it # still needs further development (it's disabled on SCO UNIX due # to an SCO bug). # # A Postfix process will pause for $in_flow_delay seconds before # accepting a new message, when the message arrival rate exceeds the # message delivery rate. With the default 100 SMTP server process # limit, this limits the mail inflow to 100 messages a second more # than the number of messages delivered per second. # # Specify 0 to disable the feature. Valid delays are 0..10. # #in_flow_delay = 1s # ADDRESS REWRITING # # The ADDRESS_REWRITING_README document gives information about # address masquerading or other forms of address rewriting including # username->Firstname.Lastname mapping. # ADDRESS REDIRECTION (VIRTUAL DOMAIN) # # The VIRTUAL_README document gives information about the many forms # of domain hosting that Postfix supports. # "USER HAS MOVED" BOUNCE MESSAGES # # See the discussion in the ADDRESS_REWRITING_README document. # TRANSPORT MAP # # See the discussion in the ADDRESS_REWRITING_README document. # ALIAS DATABASE # # The alias_maps parameter specifies the list of alias databases used # by the local delivery agent. The default list is system dependent. # # On systems with NIS, the default is to search the local alias # database, then the NIS alias database. See aliases(5) for syntax # details. # # If you change the alias database, run "postalias /etc/aliases" (or # wherever your system stores the mail alias file), or simply run # "newaliases" to build the necessary DBM or DB file. # # It will take a minute or so before changes become visible.

See canonical(5), # local(8), relocated(5) and virtual(5) for the effects this has on # aliases, canonical, virtual, relocated and .forward file lookups. # Basically, the software tries user+foo and .forward+foo before # trying user and .forward. # recipient_delimiter = + # DELIVERY TO MAILBOX # # The home_mailbox parameter specifies the optional pathname of a # mailbox file relative to a user's home directory. The default # mailbox file is /var/spool/mail/user or /var/mail/user. Specify # "Maildir/" for qmail-style delivery (the / is required). # #home_mailbox = Mailbox #home_mailbox = Maildir/ # The mail_spool_directory parameter specifies the directory where # UNIX-style mailboxes are kept. The default setting depends on the # system type. # #mail_spool_directory = /var/mail # The mailbox_command parameter specifies the optional external # command to use instead of mailbox delivery. The command is run as # the recipient with proper HOME, SHELL and LOGNAME environment settings. # Exception: delivery for root is done as $default_user. # # Other environment variables of interest: USER (recipient username), # EXTENSION (address extension), DOMAIN (domain part of address), # and LOCAL (the address localpart). # # Unlike other Postfix configuration parameters, the mailbox_command # parameter is not subjected to $parameter substitutions. This is to # make it easier to specify shell syntax (see example below). # # Avoid shell meta characters because they will force Postfix to run # an expensive shell process. Procmail alone is expensive enough. # # IF YOU USE THIS TO DELIVER MAIL SYSTEM-WIDE, YOU MUST SET UP AN # ALIAS THAT FORWARDS MAIL FOR ROOT TO A REAL USER. # #mailbox_command = /some/where/procmail #mailbox_command = /some/where/procmail -a "$EXTENSION" # The mailbox_transport specifies the optional transport in master.cf # to use after processing aliases and .forward files. This parameter # has precedence over the mailbox_command, fallback_transport and # luser_relay parameters. # # Specify a string of the form transport:nexthop, where transport is # the name of a mail delivery transport defined in master.cf. The # :nexthop part is optional. For more details see the sample transport # configuration file. # # NOTE: if you use this feature for accounts not in the UNIX password # file, then you must update the "local_recipient_maps" setting in # the main.cf file, otherwise the SMTP server will reject mail for # non-UNIX accounts with "User unknown in local recipient table". # mailbox_transport = dovecot # The fallback_transport specifies the optional transport in master.cf # to use for recipients that are not found in the UNIX passwd database. # This parameter has precedence over the luser_relay parameter. # # Specify a string of the form transport:nexthop, where transport is # the name of a mail delivery transport defined in master.cf.

The file # SMTPD_ACCESS_README provides an overview. # The header_checks parameter specifies an optional table with patterns # that each logical message header is matched against, including # headers that span multiple physical lines. # # By default, these patterns also apply to MIME headers and to the # headers of attached messages. With older Postfix versions, MIME and # attached message headers were treated as body text. # # For details, see "man header_checks". # #header_checks = regexp:/usr/local/etc/postfix/header_checks #Divert to Hold Queue #header_checks = regexp:/etc/postfix/header_checks # FAST ETRN SERVICE # # Postfix maintains per-destination logfiles with information about # deferred mail, so that mail can be flushed quickly with the SMTP # "ETRN domain.tld" command, or by executing "sendmail -qRdomain.tld". # See the ETRN_README document for a detailed description. # # The fast_flush_domains parameter controls what destinations are # eligible for this service. By default, they are all domains that # this server is willing to relay mail to. # #fast_flush_domains = $relay_domains # SHOW SOFTWARE VERSION OR NOT # # The smtpd_banner parameter specifies the text that follows the 220 # code in the SMTP server's greeting banner. Some people like to see # the mail version advertised. By default, Postfix shows no version. # # You MUST specify $myhostname at the start of the text. That is an # RFC requirement. Postfix itself does not care. # #smtpd_banner = $myhostname ESMTP $mail_name #smtpd_banner = $myhostname ESMTP $mail_name ($mail_version) # PARALLEL DELIVERY TO THE SAME DESTINATION # # How many parallel deliveries to the same user or domain? With local # delivery, it does not make sense to do massively parallel delivery # to the same user, because mailbox updates must happen sequentially, # and expensive pipelines in .forward files can cause disasters when # too many are run at the same time. With SMTP deliveries, 10 # simultaneous connections to the same domain could be sufficient to # raise eyebrows. # # Each message delivery transport has its XXX_destination_concurrency_limit # parameter. The default is $default_destination_concurrency_limit for # most delivery transports. For the local delivery agent the default is 2. #local_destination_concurrency_limit = 1 #2 #default_destination_concurrency_limit = 100 #20 # DEBUGGING CONTROL # # The debug_peer_level parameter specifies the increment in verbose # logging level when an SMTP client or server host name or address # matches a pattern in the debug_peer_list parameter. # debug_peer_level = 9 # The debug_peer_list parameter specifies an optional list of domain # or network patterns, /file/name patterns or type:name tables.

Hi folks, just step into another problem and don't know why? If i try to configure dovecot with the following: > ./configure --prefix=/test/core/dovecot --with-ssldir=/test/core/dovecot/tls --with-mysql i get > ... > checking for auth_userokay... no > checking for mysql_config... NO > checking for mysql_init in -lmysqlclient... noconfigure: error: Can't build with MySQL support: libmysqlclient not found After that i've tried to configure with following: > LDFLAGS="-L/test/core/mariadb/lib" ./configure --prefix=/test/core/dovecot --with-ssldir=/test/core/dovecot/tls --with-mysql but with same result. The Content of "/test/core/mariadb/lib" is: libmariadbclient.a libmariadb.so -> libmariadb.so.3 libmariadb.so.3 libmysqlclient.a -> libmariadbclient.a libmysqlclient_r.a -> libmariadbclient.a libmysqlclient_r.so -> libmariadb.so.3 libmysqlclient.so -> libmariadb.so.3 libmysqlservices.a pkgconfigplugin Also the Path "/test/core/mariadb/lib/pkgconfig" is in the PKG_CONFIG_PATH variable and the Library-Path "/test/core/mariadb/lib" is known by the dynamic linker (/etc/ld.so.conf.d/mylibs.conf). So what am i doing wrong? My Dovecot version: 2.3.18 My Mariadb version: 10.6.5 My OS: Ubuntu 20.04

email location - files or sql
by Robert Moskowitz 25 Feb '22

25 Feb '22

I have been running a Dovecot based mail server for over 10 years and it is time (really past) to upgrade. I really don't want to roll my own anymore. Too much time and too many skills needed. Time to retire. But still want it 'in-house'. What I am seeing is that many of the packages seem to roll the messages into some SQL database. My Dovecot setup uses the /home/vmail/doman/../{cur,new,etc} tree structure. Is there any pros vs cons on this that I can read? Is there some nice packed mailserver I can drop on a Centos-arm server that has Dovecot under the covers and I can easily rsync my current mail store to it? Mail-in-a-box looks interesting. But I have not figured out its internals and if I have to worry about anything compiled for arm that is not part of the distro. Thanks in advance for help.

Messages reappearing in mailboxes as duplicates
by Andrew Skipper 23 Feb '22

23 Feb '22

Hello, We have 3 nodes running, with a two way replication between 2 of them and a 1 way replication to a DR node running off one. We use mdbox, and directors to split traffic across nodes. There is no shared file system. Users are experiencing messages reappearing in their INBOX as unread with duplicate GUID and message headers. This occurs generally several days after a message was first received (and often actioned; read, moved, trashed, expunged, also often bulk moved/deleted). We have attempted to remove replication from the equation by cutting down to one single node with all replication disabled which did not have any impact. We have also started regular cache and mailbox purging. There are no logged events when mail items reappear, and we only observe it based on user report, mailbox inspection (doveadm looking for duplicate GUIDs/unique message headers) or seeing IMAP commands being done against the same message twice (e.g. monday they copy to trash, delete and expunge from inbox, delete and expunge from trash, then the next monday they will have to do the same for the reappearing message).

Hi there, I was just reading https://pigeonhole.dovecot.org/ and noticed that all the links to the RFCs are broken. I fixed them via regexp search & replace curl https://pigeonhole.dovecot.org/ | sed -e 's|https\?://tools.ietf.org/html/rfc$[0-9]\{4\}$/\?|https://www.ietf.org/r…' >Pigeonhole_fixed_rfc_links.html and attached the resulting page.

postfix, dovecot-lda, /run/dovecot/stats-writer socket permision and local user delivery, again
by Michael Tokarev 22 Feb '22

22 Feb '22

Hi! There are many questions on the 'net about the same theme: lda(mjt): Error: net_connect_unix(/run/dovecot/stats-writer) failed: Permission denied dovecot-lda is run from postfix as mailbox_command for local users. There's even a suggestion on dovecot wiki to make dovecot-lda setgid (to mail) - for a different reason but people use this trick to shut this error message up. See eg the last message at https://forum.zentyal.org/index.php?topic=35236.0 which points to https://wiki2.dovecot.org/LDA/Postfix . But the thing is: mail delivery stops right after making dovecot-lda setgid, like this: Feb 22 00:06:46 tsrv dovecot: lda(mjt)<253650><s+nnHub+E2LS3gMA7tuOMA>: \ Fatal: setresgid(914(dovecot),914(dovecot),8(mail)) failed with euid=1000(mjt): \ Operation not permitted why the hell lda tries to setuid to dovecot user? It will definitely unable to write to the maildir since it is owned by user mjt, not by user dovecot! And I *only* made it setgid, not setuid. How to use dovecot-lda together with postfix, after all? Thanks, /mjt

/usr/libexec/dovecot/anvil crashes immediately
by Friedrich Kink 21 Feb '22

21 Feb '22

Dear list, I built a dovecot package for openindiana (which is a Solaris derivative) from latest version 2.3.18. Everything compiles and builds fine without any issue. Even subsequent installation and startup of main dovecot process works as expected. But execution of /usr/libexec/dovecot/anvil immediately crashes. To get some more meaningful backtrace I compiled with -g. Below some facts of my environment and a backtrace. Maybe some of you are more familiar with this kind of issue as I, and can give some hint or share ideas how to nail down the problem. Or can it be a configuration issue? BTW it is running in a so-called zone. And former versions, I don't know exactly but I believe up to 2.3.17, did not show this crash. gcc --version gcc (OpenIndiana 7.5.0-il-0) 7.5.0 Configure parameters: gcc_OPT = -g CONFIGURE_OPTIONS+=

Index Corruption Problem with new VM Host - But Only With Replication Enabled
by Reuben Farrelly 21 Feb '22

21 Feb '22

Hi, I've recently migrated my two VMs across from Linode (who use KVM) onto a local VPS service (which also uses KVM). Since doing so I have started to see some strange problems with Dovecot relating to indexes and replication. I have copied the configuration files across from old host to new host. The kernel is the same - as this is Gentoo everything was rebuilt and installed from fresh, but with the same options (use flags). Even the Linux kernel is the same version with the exact same options (as is Dovecot). The filesystem is the same EXT4 with the same options too. Here is what is logged: Feb 18 15:20:41 tornado.reub.net dovecot: imap(reuben)<20031><d0yxIEPY3ROfxG3u>: Error: Mailbox INBOX: /home/reuben/Maildir/dovecot.index reset, view is now inconsistent Feb 18 15:20:41 tornado.reub.net dovecot: imap(reuben)<20031><d0yxIEPY3ROfxG3u>: Disconnected: IMAP session state is inconsistent, please relogin. in=146 out=1398 deleted=0 expunged=0 trashed=0 hdr_count=0 hdr_bytes=0 body_count=0 body_bytes=0 The trigger is the move/delete of an email. Just reading seems to be OK. But as soon as you move/delete an email this event occurs and is logged. The move fails on the first attempt (error is logged, client refreshes) but then if attempted again it succeeds. This error causes the clients to be thrown off and the client view refreshed which seems to require a redownload of everything. It is extremely disruptive to client access. The odd thing is that as soon as I disable replication by commenting out the mail_replica line, *all* of the index corruption messages and symptoms go away completely and I don't see this problem occur. As soon as I re-add it they come back. So it appears that replication at least is triggering the problem. Replication is imap1 -> imap2 and on the other host imap2 - imap1 The odd thing is that this never was a problem while the system was on Linode. I have removed all files on the remote and let dovecot re-replicate everything but this didn't help. I can go back to the VPS host and talk to them about it as I have an open ticket but from their perspective it looks like an application level problem, so there's not a lot for them to go on especially given everything else is working OK. Could the underlying host be playing a role in this? It seems unlikely given turning replication or or off causes the problem to appear or disappear. All clients are connecting to only the master of the two replication partners. Many have multiple concurrent sessions (eg my phone, and Thunderbird at the same time) but all are connecting to only one instance at a time. The second instance is only there for a failover scenario (update a DNS entry to failover). There is no NFS or any sort of sharing set up on the VMs. They are dedicated virtual disks. Can anyone give me any ideas how to troubleshoot this further or things to try?

initial replication or clone?
by Joachim Lindenberg 20 Feb '22

20 Feb '22

Hello, I want to improve availability of my dovecot installation by implementing replication as outlined in https://wiki.dovecot.org/Replication. I am wondering whether I have to install an empty copy or whether it is also an option to clone the entire existing system and then configure replication, just to avoid the initial overhead. Any input? Thanks, Joachim

Thank you! cheers, -Felipe Gasper

Using dovecot-shared for an shared index not working
by Achim Gottinger 18 Feb '22

18 Feb '22

Hello I'm in the process to migrate our mail server from version 2.2.13 with maildirs to 2.3.13 with sdbox. On the old server if we wanted an common index for the seen flag on shared folders we created an file called dovecot-shared in the mail_location folder and the mailbox folders. This does not work on the new server for all shared mailboxes the seen flag is stored per user. The log file shows this if the seen flag is changed Feb 18 13:24:15 SERVER dovecot[18887]: imap(USER)<18978><51HhlUnYeOfAwAx3>: Debug: imapsieve: mailbox shared/info: FLAG event (changed flags: \Seen) The dovecot-acl file for the shared/info/INBOX folder has the s flag set. I hope i can get a few pointers here how to get the seen flag working for all users again. On the old server the location variable for the shared folders had the variable INDEX defined which can not be used with sdbox. location = maildir:/home/vmail/%%u/mail:INDEX=/home/vmail/%u/mail/shared/%%u:INBOX=/home/vmail/%%u/mail/.INBOX Does that imply that sharing the seen flag can not be used with sdbox?

Too many wait in auth process
by ismael.tanguy＠univ-brest.fr 18 Feb '22

18 Feb '22

Hello, I'm currently benchmarking new hardware aimed to serve around 70k users For now, our IMAP server have 13k users. To run imaptest, I've spwan some bench clients. Each bench client can run imaptest with 1000 clients. More than 1000 clients will load CPU of this bench client imaptest command (command are chosen from usage stat on our other IMAP servers): imaptest host=xxxxx port=xxx userfile=userfile mbox=/root/dovecot-crlf pass=sxxxx seed=123 clients=1000 select=194 uidfetch=94 noop=70 status=82 append=49 fetch=276 list=12 store=19 expunge=22 msubs=4 search=4 logout=1 delete=81 no_pipelining With one bench client, everything runs smoothly. # ps aux | grep dovecot | awk '{print $11,$12,$13,$14,$15,$16,$17,$18}' | sort | uniq -c 1 anvil: [221 connections] (anvil) 1 auth: [13 wait, 0 passdb, 0 userdb] (auth) 1 dovecot/config 1 dovecot/imap 84 dovecot/imap-login 1 dovecot/log 20 dovecot/pop3-login 1 grep dovecot 1 stats: [1307 connections] (stats) When a second instance bench instance start imaptest, clients of first and second instance begin to stall : 1400 stalled for 20 secs in command: 1 LOGIN"fakeuser644@mailbench...." "password" And : # ps aux | grep dovecot | awk '{print $11,$12,$13,$14,$15,$16,$17,$18}' | sort | uniq -c 1 anvil: [221 connections] (anvil) 1 auth: [1227 wait, 0 passdb, 0 userdb] (auth) 1 dovecot/config 1 dovecot/imap 37 dovecot/imap-login 1 dovecot/log 20 dovecot/pop3-login 1 grep dovecot 1 stats: [680 connections] (stats) Every auth go in wait, number of connection decreases. Using mysql or a password file give same results. I have used different values for service_count with also no success. I think my use of imaptest could be false. My understanding of service auth is limited for now because I'm quite new to Dovecot (I have previously worked with Cyrus). Thank you for every hints. Ismaël Tanguy

mail-crypt and mbox format
by cincodemayo_67＠yahoo.com 17 Feb '22

17 Feb '22

Hi, My Dovecot server of many years has been set up to use mbox email folders. I want to implement mail-crypt and after banging my head against a wall for a few days trying to get mail-crypt to work I decided to try it against a test instance of my server that I reset to use Maildir format and mail-crypt worked instantly. Does mail-crypt work with mbox format mail folders, or am I wasting my time unless I switch over to Maildir? The documentation at https://doc.dovecot.org/configuration_manual/mail_crypt_plugin/ doesn't explicitly say Maildir is required. Thanks in advance, Doug

Memory problems with config service
by Víctor Rubiella Monfort 16 Feb '22

16 Feb '22

Hi all, I'm having problems with memory in config service. I increased vsz_limit to 10GB but continue with this errors when try to reload or restart dovecot: config: Panic: data stack: Out of memory when allocating 2147483688 bytes master: Error: service(config): command startup failed, throttling for 2 secs config: Fatal: master: service(config): child 5512 killed with signal 6 (core dumps disabled) Dovecot has a lot of certificates TLS configured (SNI) (about 3k), but if I check the size of all of them is aprox 170MB on disk.Why does it need so much memory to boot? Is normal? service config { vsz_limit = {{ vszlimit }} }

JWT tokens, timestamps and doubles (microseconds)
by Aleš Krajník 14 Feb '22

14 Feb '22

Hi all, I am having troubles with OAuth2 setup with local introspection of JWT tokens. This happens, when the JWT tokens contain timestamps as doubles, with microseconds, for example with the following payload: { "aud": "caf65d650022e3eb7cce518e7526a39f", "jti": "8291efed41d2ce65ec5c59a4cbcaa285f2ca37d5b2785da56de66adbd1b8eef65495bc 599be5ac56", "iat": 1644833538.793359, "nbf": 1644833538.79336, "exp": 1644833838.773605, "sub": "ales(a)example.com", "scope": "email" } Such a JWT token produces the following error: dovecot_1 | Feb 14 10:10:46 auth: Info: oauth2(ales(a)example.com,192.168.224.2,<xWZFoffXYujAqOAC>): oauth2 failed: Local validation failed: Malformed 'exp' field According to the RFC, the timestamps seem to be allowed to contain non- integer values: NumericDate A JSON numeric value representing the number of seconds from 1970- 01-01T00:00:00Z UTC until the specified UTC date/time, ignoring leap seconds. This is equivalent to the IEEE Std 1003.1, 2013 Edition [POSIX.1] definition "Seconds Since the Epoch", in which each day is accounted for by exactly 86400 seconds, other than that non-integer values can be represented. See RFC 3339 [RFC3339] for details regarding date/times in general and UTC in particular. (https://datatracker.ietf.org/doc/html/draft-ietf-oauth-json-web-token-32#se…) After removing the fractions, the token works well. This seems to be happening here: https://github.com/dovecot/core/blob/master/src/lib-oauth2/oauth2-jwt.c#L41 If you agree for this to be a bug, can I fill in a bug report somewhere? Thank you! Best, Aleš

wondering if I configured sieve vacation correctly
by Marc 14 Feb '22

14 Feb '22

I have a user who feels compelled to use the vacation as autoreply to confirm that a message has been received. The down side is of course, that if spam/abuse messages get through the spam filters, this can get 'messy'. Currently I am getting these ndr's as postmaster(?). But I was not actually expecting this. I would expect that the mailbox with the autoreply would get this report. The vacation is configured like this[1], my question is. What am I doing wrong that this ndr is not ending up in the users mailbox? Can it be the from is not correctly configured/set at the time the vacation message is being sent? [1] require ["vacation"]; # rule:[cccccccccc] if true { vacation :addresses "test(a)test.com" :from "test(a)test.com" text: dddddddddddddd } [2] Return-Path: <> Received: from aaaaa (localhost [127.0.0.1]) by aaaaa (8.14.7/8.14.7) with ESMTP id 21BDgaPj014029 (version=TLSv1/SSLv3 cipher=ECDHE-RSA-AES256-GCM-SHA384 bits=256 verify=NO) for <postyk(a)hm.edu>; Fri, 11 Feb 2022 14:42:36 +0100 Received: (from root@localhost) by aaaaa (8.14.7/8.14.7/Submit) id 21BDgamD014028 for postyk(a)hm.edu; Fri, 11 Feb 2022 14:42:36 +0100 X-Sieve: Pigeonhole Sieve 0.4.24 (124e06aa) Message-ID: <dovecot-sieve-1644586956-19320-0@bbbb> Date: Fri, 11 Feb 2022 14:42:36 +0100 From: test(a)test.com To: <postyk(a)hm.edu>

Backup procedures
by Jorge Bastos 13 Feb '22

13 Feb '22

Howdy, I have a particular situation where I have about 5 users using a large account in IMAP, and I have the need to backup the account daily or weekly or so. I was thinking about to copy the whole directory, each email is a file, it could probably work, but the dovecot index files would be damaged/wrong. Is there a tool that could perform a backup (ex: yesterday), and when I inserted that backup, it just insert the emails and folders that were deleted today? Thanks in advanced, Jorge

Dovecot installation problem (libssl_iostream_openssl.so is not portable!)
by Dimitri 11 Feb '22

11 Feb '22

Hi there, i finally solved the problem. On my server i always used openssl compiled from source with the following configuration options: > ./config --prefix=/test/dep/openssl --openssldir=/test/dep/openssl no-deprecated no-ssl The error when i try to compile dovecot tell about undefined references: > /usr/bin/ld: ./.libs/libssl_iostream_openssl.so: undefined reference to `OBJ_cleanup' > > /usr/bin/ld: ./.libs/libssl_iostream_openssl.so: undefined reference to `SSL_CTX_need_tmp_RSA' > > /usr/bin/ld: ./.libs/libssl_iostream_openssl.so: undefined reference to `SSL_load_error_strings' > > /usr/bin/ld: ./.libs/libssl_iostream_openssl.so: undefined reference to `ENGINE_cleanup' > > /usr/bin/ld: ./.libs/libssl_iostream_openssl.so: undefined reference to `ERR_free_strings' > > /usr/bin/ld: ./.libs/libssl_iostream_openssl.so: undefined reference to `EVP_cleanup' > > /usr/bin/ld: ./.libs/libssl_iostream_openssl.so: undefined reference to `SSL_library_init' > > /usr/bin/ld: ./.libs/libssl_iostream_openssl.so: undefined reference to `CRYPTO_cleanup_all_ex_data' > > /usr/bin/ld: ./.libs/libssl_iostream_openssl.so: undefined reference to `SSL_CTX_set_tmp_rsa_callback' > > /usr/bin/ld: ./.libs/libssl_iostream_openssl.so: undefined reference to `OpenSSL_add_all_algorithms' for example "OBJ_cleanup". So i check these functions on the openssl documentation an saw the notice about "deprecated function since OpenSSL 1.1.0" Therefore i recompiled openssl with the following configuration options: > ./config --prefix=/test/dep/openssl --openssldir=/test/dep/openssl --api=1.0.0 After that the compilation of dovecot was successful. It seems that dovecot still uses now deprecated functions from openssl befor version 1.1.0 Can anyone tell me when dovecot doesn't need this deprecated functions anymore? Thanks!

Hanging doveadm-server processes with dsync replication
by Sebastian Marske 10 Feb '22

10 Feb '22

Dear Dovecot mailing list, after updating Dovecot from 2.3.16 to 2.3.18 on a dsync-replicated server there are hanging doveadm-server processes piling up over time, eventually resulting in some of the affected users being shown as out of sync. Our setup is based on FreeBSD 13, ZFS and Dovecot (we use custom packages built with poudriere) with master/master replication using dsync. However, we use a shared ip (Carp), so that only one server is actually active. Please see the output of "doveconf -n" at the end for our config. Starting from an in-sync state, I updated Dovecot on the inactive server. Occasionally, Dovecot logs messages like: Feb 8 15:02:15 myhost dovecot[99800]: doveadm(someuser)<2090><ZLayIal3AmIqCAAADKIhQg>: Error: write(<local>) failed: Timed out after 60 seconds These occur for an increasing number of users (maybe 30 after two days), but not for every user (there are >4800 users on that server) and also only once for every affected user. Here's some more information about the process/user from the log entry: # doveadm replicator dsync-status username type status someuser incremental Waiting for dsync to finish (the type is "incremental for most users, but "normal" and "full" show up as well) # doveadm replicator status someuser username priority fast sync full sync success sync failed someuser low 00:01:51 21:56:06 69:56:10 y (again, not all are in failed state) # top -abp 2090 PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAND 2090 sysdov 1 20 0 26M 15M kqread 12 0:01 0.00% doveadm-server: [<local>] (doveadm-server) (didn't change for >1d) # top -m io -abp 2090 PID USERNAME VCSW IVCSW READ WRITE FAULT TOTAL PERCENT COMMAND 2090 sysdov 363 58 0 271 2 273 0.00% doveadm-server: [<local>] (doveadm-server) (didn't change for >1d) # gdb -p 2090 ...

(gdb) So I guess it's waiting for something that * doesn't happen on my system * or it didn't wait for in 2.3.16 >From what I've seen, mails from the active server (still on 2.3.16) are replicated to this server. For non-affected users, mails are also replicated from this server to the active one. I can't tell about "outgoing" replication for affected users, yet. After downgrading back to 2.3.16, things are fine again. Most affected users jump back to being successfully synced within a couple of minutes. If not, starting replication via doveadm get's them there. Testing 2.3.18 again, it seems that the same users are affected again.

Different handling of upper and lower case while indexing/searching with Solr
by Patrik Peng 10 Feb '22

10 Feb '22

Hello there We stumbled upon an user account with Solr FTS, which returned no search results for any given search query. Further investigation revealed an issue between indexing mails and querying the index. The user name contains upper and lower case characters (eg. Some.User(a)domain.net) When new mail is indexed for this user, the user name used for Solr's `user` and `id` fields are transformed into lowercase, as shown in the Solr log: webapp=/solr path=/update params={...}{add=[8543/426f3b0348d03451a3fb00008ba2b673/some.user(a)domain.net (1724281617442144256), ... (162 adds)]} 0 44298 And can be confirmed by manually querying Solr. The Solr schema in use performs no transformation for the affected fields. When a search request is performed via IMAP, Dovecot queries Solr with the original user name: GET /solr/dovecot_fts_popimap/select?wt=json&f...&fq=%2Bbox:1a30ec359dce3451b8e600008ba2b673+%2Buser:Some.User@domain.net HTTP/1.1" Which (correctly) returns zero results. To summarize, I suspect dovecot transforms any user name to lower case while indexing mails, but not when querying for results. Is this a bug, or caused by misconfiguration? Regards Patrik

Outlook 2019 and push notifications
by Laura Smith 10 Feb '22

10 Feb '22

Is there some secret config sauce I'm unaware of to get IMAP push notifications working with Outlook ? My present situation is that non-Outlook users (e.g. Apple iOS, Apple Mail etc.) work perfectly with the config below. New emails get pushed, deletes get reflected, all is happy in the world. But with Outlook nothing. You send a user an email, nothing happens in their inbox until you manually refresh by checking for new mails or waiting for the auto-check to kick in (sometimes switching between IMAP folders also does the trick). I know Outlook has a long history of being a mess when it comes to standards compliance, but surely it can't be this bad ? doveconf -n : # 2.3.18 (9dd8408c18): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.18 (0bc28b32) # OS: Linux 5.10.0-11-amd64 x86_64 Debian 11.2 xfs # Hostname: foobar.example.com auth_verbose = yes auth_verbose_passwords = sha1:7 doveadm_password = # hidden, use -P to show it imap_capability = +SPECIAL-USE imapc_features = rfc822.size fetch-headers fetch-bodystructure imapc_port = 993 imapc_ssl = imaps mail_location = maildir:/foo_data/mail/%d/%n/Maildir mail_plugins = notify replication push_notification 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 imapsieve vnd.dovecot.imapsieve namespace inbox { inbox = yes location = mailbox "Deleted Messages" { auto = no special_use = \Trash } mailbox Drafts { special_use = \Drafts } mailbox Junk { auto = subscribe special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = /etc/dovecot/local_sql_users.conf driver = sql } plugin { imapsieve_mailbox1_before = file:/etc/dovecot/imap_sieve/spam.sieve imapsieve_mailbox1_causes = COPY imapsieve_mailbox1_name = Junk imapsieve_mailbox2_before = file:/etc/dovecot/imap_sieve/ham.sieve imapsieve_mailbox2_causes = COPY imapsieve_mailbox2_from = Junk imapsieve_mailbox2_name = * sieve = file:~/sieve;active=~/.dovecot.sieve sieve_global_extensions = +vnd.dovecot.pipe +vnd.dovecot.environment sieve_pipe_bin_dir = /etc/dovecot/imap_sieve sieve_plugins = sieve_imapsieve sieve_extprograms } protocols = imap lmtp sieve service auth { unix_listener /var/spool/postfix/private/dovecot-auth { group = postfix mode = 0660 user = postfix } vsz_limit = 2 G } service doveadm { inet_listener { port = 11867 ssl = yes } } service imap-login { process_min_avail = 5 service_count = 1 } service lmtp { process_min_avail = 5 unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0660 user = postfix } user = foo_virtmail } service managesieve-login { inet_listener sieve { port = 4190 } inet_listener sieves { address = port = 5190 ssl = yes } } ssl = required ssl_ca = </etc/foobar/ssl/certificates/_.example.com.issuer.crt ssl_cert = </etc/foobar/ssl/certificates/_.example.com.crt ssl_cipher_list = ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384 ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it ssl_prefer_server_ciphers = yes userdb { args = /etc/dovecot/local_sql_users.conf default_fields = uid=foo_virtmail gid=foo_virtmail home=/foo_data/mail/%d/%n driver = sql } protocol lmtp { mail_plugins = notify replication push_notification sieve postmaster_address = foo(a)foobar.com } protocol lda { deliver_log_format = msgid=%m: %$ mail_plugins = notify replication push_notification sieve postmaster_address = postmaster quota_full_tempfail = yes rejection_reason = Your message to <%t> was automatically rejected:%n%r } protocol imap { mail_max_userip_connections = 20 mail_plugins = notify replication push_notification imap_sieve }

Config for filtering (ignoring) specific mbox mail folders?
by John Hardin 08 Feb '22

08 Feb '22

Folks: I'm migrating to Dovecot to provide IMAP services for my personal network. I have more than a couple of decades of mail in multiple (1000+) mbox mail files, but I don't care to expose all of those to IMAP. Is there any way to filter out what mail folders Dovecot will LIST and provide access to using globs or regular expressions? I'd prefer to avoid rearranging the mbox files (e.g. to subdirectories) if possible. I looked through the Dovecot documentation and didn't see anything promising, and I couldn't find any discussion of the topic online. The feature that looked like it might be closest was Namespaces, but I couldn't see how to use that to ignore specific mbox files. Is there any facility within Dovecot (or a plugin) to filter out / ignore mail folders by name, RE or file glob? Thanks in advance! -- John Hardin KA7OHZ http://www.impsec.org/~jhardin/ jhardin(a)impsec.org pgpk -a jhardin(a)impsec.org key: 0xB8732E79 -- 2D8C 34F4 6411 F507 136C AF76 D822 E6E6 B873 2E79

sieve: destination folder lookup in database?
by Hadmut Danisch 08 Feb '22

08 Feb '22

Hi, is there a way to lookup the action for an incoming mail, especially which folder to move the mail in, in a database? Given Problem: I want to replace the mda mailfilter/maildrop with dovecot/sieve. The mailfilter script is rather short, but looksup the destination folder by querying a berkeley database file with the sender's address to find the target folder, using the sender's address as an index. This way, it can store the target folder for hunders or thousands of senders, without needing to compare every single one of them by if == elsif == else... Is there a similar method for dovecot / sieve? I found that dovecot's sieve has some database connections, e.g. LDAP or https://doc.dovecot.org/configuration_manual/sieve/dict/ but rather to receive the whole sieve script for a given recipient as the owner of the mailbox. Is there a way to determine the target folder where to drop a mail into quickly by the sender's address, even for thousands, without the need to compare every single one of them? regards Hadmut

sieve script to alter subject of incoming message after lookup
by Marc 08 Feb '22

08 Feb '22

Is it possible with sieve to : 1. get sender of an email 2. lookup if this sender is present in an mailbox 3. if the sender is known, change the subject of the email. if the sender is not known, do nothing. 4. put/leave message in inbox. or maybe use dictionary (not really familiar with this) 1. get sender of an email 2. lookup if this sender is present in an dictionary 3. if the sender is known, change the subject of the email. if the sender is not known, do nothing. 4. put/leave message in inbox. But then I need something like 1. if message is dragged into a specific mailbox/folder 2. add sender to dictionary 1. if message is removed from a specific mailbox/folder 2. remove sender from dictionary

v2.3.17 quota-dict related sql errors
by Pascal Volk 06 Feb '22

06 Feb '22

Hi there, I've updated Dovecot from v2.3.14 (cee3cbc0d) to v2.3.17 (e2aa53df5b). Right after the update, dovecot begun flooding the mail.log and PostgreSQL's log. My dict sql configuration: ,--[ .../dovecot/dovecot-dict-sql.conf.ext ]-- | map { | pattern = priv/quota/storage | table = userquota | username_field = uid | value_field = bytes | } | map { | pattern = priv/quota/messages | table = userquota | username_field = uid | value_field = messages | } `-- This worked for decades. Since the update dovecot is passing the user's email address, instead the user's UID to the query. And therefor I have lots of errors in the log files: see attached `mail.log' and `postgresql-14-main.log' excerpts. The `userquota' table looks like this: Table "public.userquota" Column | Type | Collation | Nullable | Default ----------+---------+-----------+----------+--------- uid | bigint | | not null | bytes | bigint | | not null | 0 messages | integer | | not null | 0 ... Foreign-key constraints: "fkey_userquota_uid_users" FOREIGN KEY (uid) REFERENCES users(uid) ON DELETE CASCADE (full database structure: https://bitbucket.org/pvo/vmm/src/vmm-0.7.0/pgsql/create_tables.pgsql) Regards, Pascal -- Ubuntu is an ancient African word meaning “I can’t install Debian.” -- unknown

How to "activate" a mail directory?
by Peter Nabbefeld 06 Feb '22

06 Feb '22

Hello, as I need a mailbox locally only just for filtering, I've tried to manually create it (using Maildir as backend): 1. Created a folder in the appropriate location under /home/vmail with subfolders cur, new, tmp. 2. Set the same user:group as for the other folders (i.e. vmail:vmail). 3. Restarted Dovecot and Email-Client (Thunderbird). However, I cannot subscribe to the new folder. What am I missing here? Kind regards, Peter

Password Mismatch when connecting from Email Client
by Dr Francis Greaves 04 Feb '22

04 Feb '22

Dear All I have Postfix version 3.3.0, Dovecot Version 2.2.33.2 and PostfixAdmin version 3.3.10 using MySQL on a small device running Ubuntu VERSION="18.04.6 LTS (Bionic Beaver)" for my internal LAN Mail. I have a user mailto:admin@fsoft.nnet with a mailbox setup in PostfixAdmin with a password as 'Test75?' Everything is running fine, but I cannot get my Email Client Thunderbird to connect. I have setup the debugging to see that the correct password is being used, which it is, but I have this error: dovecot: auth-worker(26468): sql(mailto:admin@fsoft.nnet,10.6.10.10,<gB77wjLXGLsKBgoK>): Password mismatch (given password: Test75?) showing that dovecot disagrees!!! Why is this? Is it something to do with the permissions in PostfixAdmin? I did find https://serverfault.com/questions/696715/password-mismatch-in-dovecot-with-… where someone had the same problem. He just tried various passwords until he found one that worked!!!! I have not found any other post about this exact problem. Any help much appreciated. Regards Francis

Problem with chrooted user, manage-sieve plugin, lmtp and Thunderbird manage sieve extension: wrong symbolic link to active script
by Lev Serebryakov 04 Feb '22

04 Feb '22

I'm not sure, is it dovecot-managesieve plugin or Thunderbird extension. I have virtual users which are "chrooted" to their Maildirs, like this: user_query = SELECT '/usr/home/hosted/v-mail/%d/%n' AS chroot, \ '/' AS home, 'maildir:~/' AS mail, email.uid AS uid, email.gid AS gid FROM \ <snipped> It works perfectly. I'm using sieve and manage-sieve plugins for dovecot. `.dovecot.sieve` link is relative, like this: v-mail@onlyone:~/serebryakov.spb.ru/lev # ls -l .dovecot.sieve lrwxr-xr-x 1 root v-mail 17 Feb 4 18:19 .dovecot.sieve -> sieve/TOTAL.sieve It works. But when I deactivate/activate script via Manage sieve extension in Thunderbird link becomes absolute (with respect to chroot): v-mail@onlyone:~/serebryakov.spb.ru/lev # ls -l .dovecot.sieve lrwxr-xr-x 1 root v-mail 17 Feb 4 18:19 .dovecot.sieve -> /sieve/TOTAL.sieve and delivery agent (LMTP) start to complain: v-mail@onlyone:~/serebryakov.spb.ru/lev # grep .dovecot.sieve /var/log/dovecot.log Feb 04 18:18:42 lmtp(lev(a)serebryakov.spb.ru)<36054><iPQqEtJD/WHWjAAAlMIKZw>: Warning: sieve: file storage: Active sieve script symlink /usr/home/hosted/v-mail/serebryakov.spb.ru/lev/.dovecot.sieve is broken: Invalid/unknown path to storage (points to /sieve).

Feature request: use`openid_configuration_url` to guess OIDC endpoints and keys
by Éloi Rivard 04 Feb '22

04 Feb '22

Since version 2.3.16 dovecot has a openid_configuration_url [1] configuration parameter. Here is the documentation about this parameter: > Support for RFC 7628 OpenID Discovery (OIDC) can be achieved with > openid_configuration_url setting. Setting this causes Dovecot to report OIDC > configuration URL as openid-configuration element in error JSON. After reading the RFC I understand this brings some context to the error messages, but at first glance I would have expected more from this parameter. - Dovecot could read the userinfo_endpoint option [2] in the OIDC discovery endpoint to guess the IDP userinfo endpoint [3], and make the dovecot introspection_url parameter optional. - Dovecot could read the introspection_endpoint option [4] in the OIDC discovery endpoint to guess the IDP introspection endpoint [5], and make the dovecot tokeninfo_url parameter optional. RFC8414 is still a draft though, but there seems to be a convention about this parameter be called either token_introspection_endpoint or introspection_endpoint. Maybe both could be checked? - Dovecot could read the jwks_uri [4] option in the OIDC discovery endpoint to guess the IDP public keys, and make the local_validation_key_dict dovecot parameter optional. I would suggest to keep the values in introspection_url, tokeninfo_url and local_validation_key_dict if defined, but use the values found in the OIDC discovery endpoint by default. I think this would really help using OAUTH with dovecot. What do you think?

Dovecot v2.3.18 released
by Aki Tuomi 04 Feb '22

04 Feb '22

Hi all! We are pleased to release v2.3.18 of Dovecot. Debian/Stretch support has now been dropped. CentOS 8 packages have been replaced with RedHat Enterprise Linux 8 packages. These should be compatible with all the various variants. https://dovecot.org/releases/2.3/dovecot-2.3.18.tar.gz https://dovecot.org/releases/2.3/dovecot-2.3.18.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 -- * Removed mail_cache_lookup_finished event. This event wasn't especially useful, but it increased CPU usage significantly. * fts: Don't index inline base64 encoded content in FTS indexes using the generic tokenizer. This reduces the FTS index sizes by removing input that is very unlikely to be searched for. See https://doc.dovecot.org/configuration_manual/fts/tokenization for details on how base64 is detected. Only applies when using libfts. * lmtp: Session IDs are now preserved through proxied connections, so LMTP sessions can be tracked. This slightly changes the LMTP session ID format by appending ":Tn" (transaction), ":Pn" (proxy connection) and ":Rn" (recipient) counters after the session ID prefix. + Events now have "reason_code" field, which can provide a list of reasons why the event is happening. See https://doc.dovecot.org/admin_manual/event_reasons/ + New events are added. See https://doc.dovecot.org/admin_manual/list_of_events/ + fts: Added fts_header_excludes and fts_header_includes settings to specify which headers to index. See https://doc.dovecot.org/settings/plugin/fts-plugin#plugin-fts-setting-fts-h… for configuration details. + fts: Initialize the textcat language detection library only once per process. This can reduce CPU usage if fts_languages setting has multiple languages listed and service indexer-worker { service_count } isn't 1. Only applies when using libfts. + lib-storage: Reduced CPU usage significantly for some operations that accessed lots of emails (e.g. fetching all flags in a folder, SORT, ...) + lib: DOVECOT_PREREQ() - Add micro version which enables compiling external plugins against different versions of Dovecot. + lmtp: Added new lmtp_verbose_replies setting that makes errors sent to the LMTP client much more verbose with details about why exactly backend proxy connections or commands are failing. + submission: Support implicit SASL EXTERNAL with submission_client_workarounds=implicit-auth-external. This allows automatically logging in when SSL client certificate is present. - *-login: Statistics were disabled if stats process connection was lost. - auth: Authentication master user login fails with SCRAM-* SASL mechanisms. - auth: With auth_cache_verify_password_with_worker=yes, passdb extra fields in the auth cache got lost. - doveadm: Fixed crash if zlib_save_level setting was specified, but zlib_save was unset. v2.3.15 regression. - doveadm: Proxying can panic when flushing print output. v2.3.17 regression. Fixes: Panic: file ioloop.c: line 865 (io_loop_destroy): assertion failed: (ioloop == current_ioloop) - doveadm: stats add --group-by parameter didn't work. - fts: Using email-address fts tokenizer could result in excessive memory usage with garbage email input. This could cause the indexer-worker processes to fail due to reaching the VSZ memory size limit. Only applies when using libfts. - imap: A SEARCH command timing out while fts returns indexes may timeout returning "NO [SERVERBUG]", while it should return "NO [INUSE]" instead. - imap: LIST-EXTENDED doesn't return STATUS for all folders. Sending LIST .. RETURN (SUBSCRIBED STATUS (...)) did not return STATUS for folders that are not subscribed when they have a child folder that is subscribed as mandated by IMAP RFCs. - imapc: Mailbox vsize calculation crashed with Panic: file index-mailbox-size.c: line 344 (index_mailbox_vsize_hdr_add_missing): assertion failed: (mails_left > 0) - indexer: If indexer-worker crashes, the request it was processing gets stuck in the indexer process. This stops indexing for the folder until indexer process is restarted. v2.3.14 regression. - indexer: Process was slowly leaking memory for each indexing request. - lib-event: Unnamed events were wrongly filtered out for event/metric filters like "event=abc OR something_independent_of_event_name". - lib-index: 64-bit big endian CPUs handle last_used field in dovecot.index.cache wrong. - lib-ssl-iostream: Fix buggy OpenSSL error handling without assert-crashing. If there is no error available, log it as an error instead of crashing. The previous fix for this in v2.3.11 was incomplete. Fixes Panic: file istream-openssl.c: line 51 (i_stream_ssl_read_real): assertion failed: (errno != 0) - lmtp: Out-of-memory issues can happen when proxying large messages to LMTP backend servers that accept the message data too slow. - master: HAProxy header parsing has read buffer overflow if provided header size is invalid. This happens only if inet_listener { haproxy=yes } is configured and only if the remote IP address is in haproxy_trusted_networks. - old_stats: Plugin kept increasing memory usage, which became noticeable with long-running imap sessions. - stats: Dynamically adding same metric multiple times causes multiple stats. - submission-login: Authentication does not accept OAUTH2 token (or other very long credentials) because it considers the line to be too long. - submission-login: Process can crash if HELO is pipelined with an invalid domain. - submission-proxy: Don't use SASL-IR if it would make the AUTH command line longer than 512 bytes. - submission: Service would crash if relay server authentication failed. - virtual: FTS search in a virtual folder could crash if there are duplicate mailbox GUIDs. This mainly happened when user had both INBOX and INBOX/INBOX folders and the namespace prefix was INBOX/. Fixes Panic: file hash.c: line 252 (hash_table_insert_node): assertion failed: (opcode == HASH_TABLE_OP_UPDATE) - virtual: If mailbox opening fails, the backend mailbox is leaked and process crashes when client disconnects. Fixes Panic: file mail-user.c: line 232 (mail_user_deinit): assertion failed: ((*user)->refcount == 1) - virtual: Searching headers in virtual folders didn't always use full-text search indexes, if fts_enforced=no or body.

How to use virtual "All" and "Flagged" mailbox?
by A B 01 Feb '22

01 Feb '22

Hello, I'm trying to use the virtual "All" and "Flagged" mailboxes as described in 15-mailboxes.conf. The information here ( https://doc.dovecot.org/configuration_manual/virtual_plugin/) doesn't really touch on how to actually interact with the virtual mailboxes. My presumption is that when I mark an email message in the Inbox as FLAGGED (and I can confirm the \Flagged flag has been set) then I should then be able to either (1) see a copy of that message in the virtual.Flagged folder, or (2) when I use an imap command to get the message nums or whatever from the virtual.Flagged folder/mailbox, it should return the message that is flagged in the inbox as a result. Additionally, I'm presuming that for each new user that automatically gets added, I would have to create my own script that would add the dovecot-virtual file, dovecot doesn't do that on its own. When I view the user's directory I see these folders were created: --- [snippet] drwxrwx---. 5 vmail vmail 135 Jan 25 17:01 .virtual.All/ drwxrwx---. 5 vmail vmail 158 Jan 25 17:14 .virtual.Flagged/ [.virtual.Flagged]# ll total 20 drwxrwx---. 5 vmail vmail 158 Jan 25 17:14 ./ drwxrwx---. 20 vmail vmail 4096 Jan 25 17:33 ../ drwxrwx---. 2 vmail vmail 6 Jan 25 16:58 cur/ -rw-rw----. 1 vmail vmail 868 Jan 25 16:58 dovecot.index.cache -rw-rw----. 1 vmail vmail 384 Jan 25 17:01 dovecot.index.log -rw-rw----. 1 vmail vmail 51 Jan 25 17:01 dovecot-uidlist -rw-r--r--. 1 vmail vmail 8 Jan 25 17:14 dovecot-virtual -rw-rw----. 1 vmail vmail 0 Jan 25 16:58 maildirfolder drwxrwx---. 2 vmail vmail 6 Jan 25 16:58 new/ drwxrwx---. 2 vmail vmail 6 Jan 25 16:58 tmp [.virtual.Flagged]# cat dovecot-virtual * flagged --- Side note: This set-up uses the php-imap library to interact with Dovecot.

Quota: read how much diskspace is available?
by Hans van Zijst 01 Feb '22

01 Feb '22

Hi, I've been trying to get domain quotas to work for a while, but to no avail so far. Is there a way to let Dovecot simply check how much space is still available in a directory? I'm using GlusterFS as my mailstore, so I can configure quotas per directory. All I need is a way to let Dovecot check quota in a way like "df /var/vmail/<domain>". Kind regards, Hans

Set mail crypt private password with OAUTH?
by Max Kostikov 31 Jan '22

31 Jan '22

We currently use Dovecot and mailbox encryption via the mail-crypt-plugin. With standard password authentication, we set the value of the individual password to encrypt the contents of the userdb_mail_crypt_private_password mailbox in the SQL query. Is it possible to set the userdb_mail_crypt_private_password value when authenticating via OAUTH2 ? -- Best regards, Max Kostikov

silly quesiton
by steph.mag220＠netcourrier.com 31 Jan '22

31 Jan '22

Hi, Up to now, I used PAM of each user in order to send and receive email. ( BTW, sending email, a use authentication was required and we used the login and passwd of the user on the system Now, for dovecot, I start to use MD5 passwrd.. and that sounds to be OK auth_mechanisms = plain login cram-md5 passdb { driver = passwd-file # Path for passwd-file. Also set the default password scheme. args = scheme=cram-md5 /etc/cram-md5.pwd } But changing the passwrd for the user1.. he can retrieve emails from dovecot, but cannot send anymore, because sending emails kept the old passwrd. ( using the PAM) 1) How can I says sendmail to use the same passwd file ( with MD5) than dovecot ? 2) Ideally, I would like to create virtual users for the same mailbox Is that possible ? like 2 files Users and PAsswrds pointing out the mailbox : maildir :/home/mailbox/user1 ex : user1(a)foo.com passwrd1 /home/mailbox/generic_mails and user2 passwrd2 home/mailbox/generic_mails How can I do that ? Thanks for your help

Dovecot is the latest 2.3.17.1 My OS is Ubuntu 21.04 Can anyone help me with this please? Thanks!

Sync via ssh fails when ssl is active
by Johan 31 Jan '22

31 Jan '22

I have computers at two different locations and one computer running dovecot at each place. I sync my emails between these two servers using ssh and I haven't had any problems with this lately until I upgraded dovecot recently. I now get the following error at location "alfa" when trying to sync with dovecot at location "delta" Jan 20 16:13:09 doveadm: Error: doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/10-ssl.conf line 16: ssl_cert: Can't open file /etc/letsencrypt/live/delta.oxyl.net/fullchain.pem: Permission denied Jan 20 16:13:09 dsync-local(johan(a)oxyl.net)<FWBVNQN86WH52iQA1AGq6A>: Error: read(vmail(a)192.168.119.12) failed: EOF (version not received) Jan 20 16:13:09 dsync-local(johan(a)oxyl.net)<FWBVNQN86WH52iQA1AGq6A>: Error: Remote command returned error 89: ssh -q -p 22 -o StrictHostKeyChecking=no -i /datastorage/epost/vmail/.ssh/id_ecdsa -lvmail 192.168.119.12 doveadm dsync-server -ujohan(a)oxyl.net Trying to sync from "delta" i get the same error but the domain is changed in the error-message to 'alfa.oxyl.net' I can read mail at both locations using STARTTLS. There is no error in dovecot.log when I restart the service. If I disable ssl and comment out ssl_cert/ssl_key in 10-ssl.conf I have no trouble performing sync between servers. If I run the ssh-command in the error-message as user vmail I get the same ssl-error as above. Any ideas how to solve this? /Johan Pålsson

Dsync replication - delayed replication (Sync lock)
by Daniel Botting 31 Jan '22

31 Jan '22

Hi, *Our setup:* Two Debian 10 machines that are setup to replicate mail between them, we have round robin DNS setup so a user can connect to either server. *What should happen:* Mail is delivered to either server and replicated across straight away to their mailbox on the other server so it does not matter which one they are connected to they will receive it fairly soon after delivery. *What actually happens:* In some instances the user will experience a delayed receipt of messages if they are not connected to the server that the message is initially delivered to, sometimes the delay is 5/10 minutes, we had a recent support ticket submitted where it was over an hour. Error message seen in mail.err: Sep 1 10:16:15 <host name> dovecot: dsync-local(<username>)<WELSGEERTl8FEAAAZJ7A9A>: Error: Couldn't lock /path/to/mailbox/.dovecot-sync.lock: fcntl(/path/to/mailbox/.dovecot-sync.lock, write-lock, F_SETLKW) locking failed: Timed out after 30 seconds (WRITE lock held by pid 3697) Process 3697 is dovecot/doveadm-server. *Doveconf -n output:* # 2.3.10.1 (a3d0e1171): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.10 (67bf5bd7) # OS: Linux 4.19.0-10-amd64 x86_64 Debian 10.5 # Hostname: <server hostname> auth_verbose = yes default_vsz_limit = 0 doveadm_password = # hidden, use -P to show it first_valid_gid = 8 first_valid_uid = 8 last_valid_gid = 8 last_valid_uid = 8 lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes mail_gid = 8 mail_location = maildir:~/Maildir mail_plugins = " notify replication" mail_uid = 8 managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex im ap4flags copy include variables body enotify environment mailbox date index ihave duplicate mime foreverypart extracttext editheader imapfla gs namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { mail_replica = tcps:<server being replicated to>:<port being used> sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_extensions = +editheader +imapflags } postmaster_address = postmaster@<domain address> protocols = " imap sieve pop3" replication_max_conns = 12 service aggregator { fifo_listener replication-notify-fifo { user = mail } unix_listener replication-notify { user = mail } } service auth { unix_listener /var/run/dovecot-exim-bridge { mode = 0660 user = Debian-exim } } service doveadm { inet_listener { port = <port being used for replication> ssl = yes } } service imap-login { inet_listener imap { port = 143 } } inet_listener imaps { port = 993 ssl = yes } process_limit = 512 process_min_avail = 4 service_count = 1 } service imap { process_limit = 1024 } service managesieve-login { inet_listener sieve { port = <sieve port> } process_min_avail = 1 service_count = 8 vsz_limit = 256 M } service managesieve { process_limit = 1024 } service replicator { process_min_avail = 1 unix_listener replicator-doveadm { mode = 0666 } } ssl = required ssl_cert = </path/to/ssl/cert/fullchain.pem ssl_cipher_list = ALL:!LOW:!SSLv2:!EXP:!aNULL ssl_client_ca_dir = /etc/ssl/certs ssl_key = # hidden, use -P to show it ssl_min_protocol = TLSv1.2 userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap override_fields = home=/var/mail/%u uid=mail gid=mail } protocol lda { mail_plugins = " notify replication sieve" } protocol imap { mail_max_userip_connections = 32 mail_plugins = " notify replication" } protocol sieve { mail_max_userip_connections = 10 managesieve_logout_format = bytes=%i/%o managesieve_max_line_length = 65536 } Kind regards Daniel

Non-unique Message ID in mail messages
by Daniel Ryšlink 28 Jan '22

28 Jan '22

Hello! I apologize for bringing perhaps trivial/well-known matter, but I am interested in your opinion. RFC 5322 clearly states that mail messages SHOULD contain a Message ID identifier, but if the do contain it, it MUST be globally unique. Despite this requirement, I have encountered senders (namely Spamcop) that sends obviously different (albeit related) messages called "Alert" and "Summary" (they are always related to the same incident and have the same Message ID). This creates all sorts of problems when processing these mails, namely with users that have local forwards from one domain to another (our mailserver hosts multiple domains), because for example Dovecot refuses to forward the second message, flagging it as a duplicate. My question to you is - did you also encounter similar incorrect (according to RFC standards) problem, and if so, is there a way to persuade dovecot to perhaps determine the uniqueness of a message by other means than just checking the message ID (i.e. look at other identifiers, Subject, perhaps)? Because according to the log records, Spamcop does not seem to be the only offender. Thanks in advance for any reactions, and if I did something wrong by writing this message, I apologize again in advance. If required, I can provide samples of the Spamcop messages. -- --===============-- --== Best Regards! ==-- --===============-- Daniel Ryšlink Sysadmin @ Quantcom.cz Czech Republic

hi Christian >Did the password hash algorithm change between devuan 3 and 4? >You can check that in your /etc/shadow file. As I understand, devuan is pretty much debian without systemd? And that if you were prepared to do a fair bit of work you could start with debian installed, hack it about and end up with something like devuan? I doubt devuan has done anything to deviate from debian at this level and both machines were recently dist-upgraded. Dovecot needed no tinkering with at all on the debian machine. >The start of the password field should be the same something like $6$... > Yes it is on devuan 4. I no longer have anything with devuan 3 to check that, but it shouldn't have changed in a dist-upgrade? Interestingly, although it's the same user and password on both machines, I notice that the hashes in /etc/shadow are not identical after the commencing $6$. But then I don't know how these hashes are derived, so maybe that is not unexpected? -- David Matthews mail(a)dmatthews.org

doveadm backup : Warning: Deleting mailbox GUID= is missing locally
by Laura Smith 28 Jan '22

28 Jan '22

Hi, As per the docs (https://wiki.dovecot.org/Tools/Doveadm/Sync) I'm presently running doveadm backup multiple times with a view to eventual server migration. I am seeing messages such as this: Warning: Deleting mailbox 'Junk': UID=1826 GUID= is missing locally Is it anything to worry about ? If so, how should I be dealing with it. I also have a further question. It is not clear from the docs what the role of the "-R" flag is in relation to "doveadm backup" ? Surely by definition backup = remote -> local ? Thanks ! Laura

Question regarding delivery from Postfix via LMTP proxy
by Vlad Sedov 28 Jan '22

28 Jan '22

Hello, I'm using Postfix with Dovecot 2.3.13, and trying to get LMTP proxy to work for authentication and delivery in the following scenario: Incoming Mail -> Postfix (server A) -> LMTP to Dovecot (server A) -> LMTP to Dovecot (server B) I'm using MySQL for authentication. I've created a user on both server A and server B, test(a)domain.tld On server A, host parameter in password_query for test(a)domain.tld is set to server B's address, and proxy_maybe is enabled. Delivery and authentication to Server A works fine. Authentication and IMAP proxy to server B works fine as well. I can connect to IMAP on server A with credentials for test(a)domain.tld and access the maildir on server B. This works surprisingly well, and is about half the battle for me.. What I can't figure out, is how can I get Postfix to deliver mail using LMTP via server A to server B.. Currently, mail still gets delivered to the user's maildir on server A. Is this possible with Dovecot alone, or do I need to use another method to get messages to hop to server B via server A? Any help would be appreciated.. cheers, Vlad

hi Christian Same user and password on both machines, users with shell accounts; exactly the same; in fact I'm struggling to see anything different that might be relevant. On one machine dovecot just works on the other, it stopped working after a dist-upgrade. One machine (where it works) is a debian 11 VPS, the other is real PC hardware running devuan 4, but their dovecot is a debian package. I can't see why either of that should matter and dovecot also just worked on the PC with devuan 3. I've tried purging dovecot-core and dovecot-imapd and reinstalling to no effect. > > 1.

doveadm stateful backup
by Christian 26 Jan '22

26 Jan '22

Hi all, first: I'm using version 2.3.4.1 I manage some rather large imap mailboxes which I want to backup on a regular basis. Some of them have relatively heavy traffic and one of them is greater than 30GB in size. I studied the docs for doveadm backup (https://wiki2.dovecot.org/Tools/Doveadm/Sync) and even did some code research to better understand the process. The docs state that using stateful synchronization is the most efficient way to synchronize mailboxes, therefore I chose this approach. Highlevel overview: - store a copy of the whole maildir in a separate directory (/var/vmail/backup) - backup to this directory once a minute (trying to make most use of transaction logs) using the last state stored within a file - create a backup once a day using tar (full, differential and incremental ones) blocking the backup process of the before mentioned step I quite often receive notifications that doveadm backup returned an exit code of 2, which should be quite normal. These notifications look like that: dsync(another_address(a)my.domain): Warning: Failed to do incremental sync for mailbox INBOX, retry with a full sync (Modseq 171631 no longer in transaction log (highest=177818, last_common_uid=177308, nextuid=177309)) dsync(another_address(a)my.domain): Warning: Mailbox changes caused a desync. You may want to run dsync again: Remote lost mailbox GUID e9149d0ae4e02d532505000026ca4352 (maybe it was just deleted?) Synced another_address(a)my.domain successfully but missing some changes. Took 3 seconds. Starting retry 1... The first message seems to point out that the transaction log got rolled and no more contains the messages from the backup dir, right? I thought about setting mail_index_log_rotate_min_age to 1hour to prevent rolling transaction logs too often, but abandoned this thought and increased the backup interval to once a minute. The warnings still appear so maybe my thoughts about transactions logs are wrong. The second message seems less alarming to me. How does doeveadm backup behave in such situations? Does it directly fall back to a less efficient way of syncing mails? Does the state store the information "retry with a full sync" and the next run uses this mode? To investigate on this I simply measured runtimes an saw that the second/retry run takes a bit longer (up to about 15 seconds) to sync the dir. I'm afraid of losing messages using my approach. Is it safe to always use doveadm backup -s $state? Simply counting one maildirs files within the live directory and the backup copy shows a 100 fewer files within the backup dir although the script runs only since a few days. For reference, see my backup script below.

pop3-login logging double Disconencted
by Noel Butler 26 Jan '22

Hi all, Wondering if anyone else is seeing this double Disconnected in the logs with current stable version, it only happens for pop3-login, and only with Too many commands... other pop3-login logging with Disconnected like Connection closed (no auth attempts... etc are fine Example of anomaly - pop3-login: Info: Disconnected: Disconnected: Too many bad commands (no auth attempts in ... If anyone running 2.3.17.1 sees this or does not see it on Too many bad... or at all, kindly mind letting me know, not sure if something has gone haywire here or its a bug that needs reporting since logs indicate this only occurred after updating to the point 1 release. -- Regards, Noel Butler This Email, including attachments, may contain legally privileged information, therefore at all times remains confidential and subject to copyright protected under international law.

noob maildir question
by mikfum 25 Jan '22

25 Jan '22

I would like to ask if it is an acceptable practice to manage messages in the maildir as a file (move them from one folder to another) while dovecot is in stop state thinking that it will be rebuild to the next imap user login thanks for your patience:) mik

S3 integration w Dovecot
by Martin Olsen 21 Jan '22

21 Jan '22

Good morning, day, evening :P As stated on documentation S3-compatible Storages — Dovecot documentation <https://doc.dovecot.org/configuration_manual/mail_location/obox/s3/> only AWS S3 is officially supported. However, we know that Scality has been successfully integrated at some larger corporations. Particularly curious if anyone has integrated with Pure S3 object storage solution, or any other for that matter? Just looking at some different options. - Sincerely, Martin.

sockets created for lmtp
by Mike 20 Jan '22

20 Jan '22

Was recently configuring lmtp to listen in the postfix spool for mail. I set the socket as suggested in the documentation, however, when I look at what sockets were created there was an additional one for dovecot. Since I made the change, my expectation would have been just the one that I set up. I doubt it impacts it negatively, but I wanted to understand if I configured things correctly or not. Thanks. Mike

FTS Tokenization filters normalizer-icu vs lowercase
by Alessio Cecchi 20 Jan '22

20 Jan '22

Hi, I'm trying to setup fts-flatcurve with tokenization. What are the differences/benefits with "fts_filters = normalizer-icu" vs "fts_filters = lowercase"? Reading the Doc I found about normalizer-icu "This is potentially very resource intensive." and about lowercase "Supports UTF8, when compiled with libicu". So, using lowercase is almost the same that normalizer-icu but faster? FYI for using fts-flatcurve with dovecot RPM packages from repo.dovecot.org you have to rebuild with --with-icu --with-stemmer --with-textcat and related library. Thanks -- Alessio Cecchi Postmaster @ http://www.qboxmail.it https://www.linkedin.com/in/alessice

Save of messages slow when replica unavailable
by Jörg Faudin Schulz 20 Jan '22

20 Jan '22

We have a setup with a dovecot server + replica. This works fine as long as the replica is available. When the replica is not available for some reason, the clients can work normally with one exception: the saving of sent messages to their inboxes takes ages. Thunderbird times out and complains (and duplicates the message), mail.app just waits until it's done. Is there any setting that helps here? For the time being, I deactivated replication; but this isn't a long time solution. Thank you for all your work&support, appreciating the doc as well.

lmtp_save_to_detail_mailbox: " If the recipient address includes a detail element / role (as in user+detail format), save the message to the detail mailbox. " Im not understanding this, what is the "detail mailbox"? I tried testing this feature by setting "lmtp_save_to_detail_mailbox = yes" and sending an email to user+test(a)example.com. The email still ended up in the default inbox folder. So what does lmtp_save_to_detail_mailbox do or is there another setting that also needs to be set to use this feature?

Outlook vs. Dovecot experience
by Vladislav Kurz 18 Jan '22

18 Jan '22

Dear colleagues, what is your experience regarding using outlook (2016/365) as IMAP client and dovecot on server side? We have sync issues with outlook vs. cyrus IMAP server, and we consider moving to dovecot. But before that I'd like to hear from others if this combination works well. Especially if users have large and bushy mailboxes (>10 GB, >100 mailboxes), two mailboxes (accounts) on the same server. I don't want to do the migration just to find out that it is general issue of outlook vs. any IMAP server. -- Best regards Vladislav Kurz

JA3/JA3S as a Dovecot plugin?
by Sidsel Jensen 18 Jan '22

18 Jan '22

Hi We have been looking a bit into JA3 (https://engineering.salesforce.com/tls-fingerprinting-with-ja3-and-ja3s-247… <https://engineering.salesforce.com/tls-fingerprinting-with-ja3-and-ja3s-247…> and https://blog.squarelemon.com/tls-fingerprinting/ <https://blog.squarelemon.com/tls-fingerprinting/> ) for possible threat actor identifications. Roughly speaking you can think of JA3 as the TLS equivalent of the User-Agent string. Has anybody been looking into the possibility of building an open source dovecot JA3 plugin? I’d also like to hear the technical pros/cons of doing so…and perhaps the ethical deliberations also :-) Kind Regards, Sidsel

FTS flatcurve not index messages when SEARCH run on Virtual Mailboxes
by Alessio Cecchi 18 Jan '22

18 Jan '22

Hi, I'm testing FTS flatcurve plugin in order to understand if I can switch from FTS Solr to flatcurve. In my configuration I have enabled Virtual mailboxes and for search in all folders I just SEARCH on Virtual/All folder. I this (virtual) folder is not indexed with FTS Solr Dovecot start to index it (or all real folders). But with FTS flatcurve when I SEARCH on Virtual/All for the first time the indexer process does not start and the search return empty. Only if I run manually "doveadm index -q -u alessio(a)email.net '*'" flatcurve find messages. Can flatcurve have the same feature as Solr for Virtual mailboxes? Here a sample of my configuration: namespace Virtual { hidden = yes list = no location = virtual:/etc/dovecot/virtual:INDEX=~/Maildir/virtual prefix = Virtual/ separator = / subscriptions = no } namespace inbox { [...] mailbox virtual/All { comment = All my messages special_use = \All } } # cat /etc/dovecot/virtual/All/dovecot-virtual * all Thanks -- Alessio Cecchi Postmaster @ http://www.qboxmail.it https://www.linkedin.com/in/alessice

Extracting CLIENTID information from checkpassword or postlogin scripting
by Dan Conway 18 Jan '22

18 Jan '22

Hello, When extracting client_id information from the client connection (i.e. setting imap_id_log = *) the information is directly logged by Dovecot as such: ID sent: name=Thunderbird, version=91.5.0 My question is, Is it possible to export/set this information in a checkpassword script or a postlogin script? client_id If|imap_id_retain| <https://doc.dovecot.org/settings/core/#core_setting-imap_id_retain>is enabled this variable is populated with the client ID request as IMAP arglist. I've enabled both checkpassword and postlogin on a test server, as well as 'imap_id_retain' set to 'yes'. I wrote a simple Perl script that dumps everything in %ENV as well as @ARGV for checkpassword and postlogin, but I don't see any occurrences of ID information. I've also tried to see if I could supply that variable in dovecot.conf by setting 'client_id' as a parameter, but that didn't seem to do the trick either. passdb { ... # Doesn't work args = /usr/local/bin/checkpassword.pl client_id # Doesn't work args = /usr/local/bin/checkpassword.pl %{client_id} ... } What am I missing? Is it possible to get these variables into an external script that checkpassword or postlogin executes? Thanks.

Order of loading and checking userdb on Ubuntu
by Mike 16 Jan '22

16 Jan '22

When using the lmtp service for local delivery, I'd like to change the user lookup to only use the user portion of the email address. I think I do that in the 20-lmtp.conf file, but not exactly sure how. From what I've found on the web, I just need to change the auth_username_format=%n. I feel confident that I'm not doing it right. older posts implied that the order things are loaded is an issue, but not sure if that is the case anymore. My goal is to set username_format for only lmtp. Thanks for any help.

Wrong timestamp value in name of file
by Ervin Hegedüs 14 Jan '22

14 Jan '22

Hi there, Debian 10, Dovecot 2.3.4 (1:2.3.4.1-5+deb10u6), ext4 mailstore. A user on our server reorganized the sent items: he moved few items from the old sent folder into a new one. After that, he noticed me that he does not see every mail, but when he starts a search, then he finds it. I looked up the mail, and found this situation: # ls -la 1642152396.M997381P21341.mail2\,S\=473164\,W\=479469\:2\,S -rw-r--r-- 1 vmail vmail 473164 aug 24 10:21 '1642152396.M997381P21341.mail2,S=473164,W=479469:2,S' # grep Date '1642152396.M997381P21341.mail2,S=473164,W=479469:2,S' Date: Tue, 24 Aug 2021 10:21:39 +0200 # date -d @1642152396 Fri Jan 14 10:26:36 CET 2022 As you can see that mail had sent on 24 Aug, 2021, but after the reorganization it got a new timestamp with the date of today. I assume the client (iPhone) orders the mail by the name of files - am I right? Why did this happen? How can I fix that? I mean, is there any way to rename this files (a few hundred...) to the "real" timestamp? Thanks, a.

ssl=required per user?
by Arkadiusz Miśkiewicz 13 Jan '22

13 Jan '22

Can ssl=required be forced on per user setting? Right now I could modify password_query to check if %c (%{secured}) is empty and return appropriate error as "reason" like in https://doc.dovecot.org/configuration_manual/authentication/nologin/#authen… example. Unfortunately password_query is a bit too late. I would like to deny access as soon as possible, so just after user sends his login. (that won't help much in cases when client sends password early like "AUTH PLAIN b64loginpass" but will help in all other cases) user_query doesn't have this capability that password_query it seems. -- Arkadiusz Miśkiewicz, arekm / ( maven.pl | pld-linux.org )

Migrate mail_location
by hello＠reox.at 11 Jan '22

11 Jan '22

Hi! I have a dovecot installation, with the following configuration: mail_home = /var/vmail/%d/%n mail_location = maildir:~ I would like to migrate the mail_location to maildir:~/mail, to get around the issues described in the documentation. But I can not really find a good way to do that. I played around with doveadm sync/backup, but I can only copy everything into a new location (i.e. doveadm sync maildir:~/mail), but this does not really untangle the mail_home and location. My other idea was to migrate the maildir manually, i.e. move the maildir related folders and files (new, cur, tmp, all folders starting with a dot and containing itself {new,cur,tmp}, dovecot.* files, subscriptions file) into the ~/mail folder, but I'm not sure if this is a safe method. Is there any safe method to do this using dovecot tools? If the only way is a offline migration, I'm fine with that. Best, Sebastian

Spamassassin fails
by Hans Brage 10 Jan '22

10 Jan '22

Hi! I've been running a server with Dovecot, Sieve, Spamassassin and getmail to handle my emails for several years now. Just before christmas I did one of these regular updates and since then I got problems with spamassassin. Quite a lot of spam is not been filtered out. I can see a lot of errors like these in the mail-log. spamd: failed to create readable default_prefs: /home/vmail/.spamassassin/user_prefs Vmail is the user that is running my scripts that retrieves email and executes spamc. Any ideas? Regards, Hans

outlook 2019 not working
by postmaster 10 Jan '22

10 Jan '22

Just tried connecting a Windows 10 client with Outlook 2019 but it fail's on both POP3 or IMAP - i knew it was working when i tested it after the server setup about a year ago because i documented everything with screenshots. All other devices we use (Thunderbird, iPhone/iPad, Android devices, RoundCube) are working without any issue, just Outlook won't connect anymore. We don't have much Windows/Outlook experience - any help/hints appreciated. This what i have in the logs, but doesn't see anything that helps: 2022.01.10 02:22:25 pop3-login: Debug: SSL: where=0x10, ret=1: before SSL initialization 2022.01.10 02:22:25 pop3-login: Debug: SSL:

Patch: assertion failed in doveadm fts lookup
by John Fawcett 09 Jan '22

09 Jan '22

Hi I'm reposting this patch, which I have been applying locally since I originally posted it. Hopefully it can be considered for inclusion in the official release. It was tested on dovecot 2.3.16 but applies against the latest version 2.3.17.1.

Non-user logins?
by Ken Wright 09 Jan '22

09 Jan '22

My Dovecot issues continue. Right now I see at least two issues: first, my logs consistently show non-users trying (and failing) to log in, and I'm still unable to log in from my email client (Evolution or Roundcube, either one). I'll post about the second issue later; right now I wonder why I'm getting so many non-users trying to log in. Am I the subject of concerted hacking attacks, or is there something else going on? Some of the attempted logins are more-or-less random names claiming to be @mydomain, but at least one is a username that's really on my server, to wit: Jan 7 22:52:01 grace dovecot: lmtp(776281): Error: lmtp-server: conn unix:pid=776262,uid=117 [3]: rcpt www-data(a)mydomain.com: Failed to lookup user www-data(a)mydomain.com: Internal error occurred. Refer to server log for more information. (Another quick question: which server log should I check?) So, if anyone can tell me what's going on with all these logins, I'd be much obliged! Ken

Patch: enhancements for solr/tika integration
by John Fawcett 09 Jan '22

09 Jan '22

Hi here's a patch with some enhancements that I am applying locally for solr/tika integration. Hopefully this can be considered for inclusion. I've tested up to 2.3.16 and this patch applies against latest version 2.3.17.1. The contents are: 1. Allow username and password in tika configuration (as is already supported for solr). For example: fts_tika = https://user:password@tika_host:tika_port/tika/tika This means that tika can be more easily located on a different server to dovecot. Locating Solr and Tika on separate servers can isolate the Dovecot server from issues that may happen on Solr or Tika (like out of memory). 2. Introduce an optional configurable limit on the size of emails whose message bodies will be indexed with solr via a new setting fts_max_size, to be put in the plugin section. For example plugin { ... fts_max_size = 2M ... } Message body indexing is skipped for messages that are larger than this setting. 3. Introduce an optional configurable limit on the size of emails whose attachments will be sent to tika for keyword extraction, via a new setting fts_max_size_tika, to be put in the plugin section. For example: plugin { ... fts_max_size_tika = 1M } I noticed that some very large attachments are being sent to tika and these often do not have any useful content to index. For simplicity the check is done on message size not individual or total attachment size. Here's the patch: diff -ur dovecot-2.3.17.1-orig/src/plugins/fts/fts-build-mail.c dovecot-2.3.17.1-new/src/plugins/fts/fts-build-mail.c --- dovecot-2.3.17.1-orig/src/plugins/fts/fts-build-mail.c 2021-12-03 12:48:47.000000000 +0100 +++ dovecot-2.3.17.1-new/src/plugins/fts/fts-build-mail.c 2022-01-09 01:33:23.398341998 +0100 @@ -17,6 +17,7 @@ #include "fts-filter.h" #include "fts-api-private.h" #include "fts-build-mail.h" +#include "settings-parser.h" /* there are other characters as well, but this doesn't have to be exact */ #define IS_WORD_WHITESPACE(c) \ @@ -25,6 +26,8 @@ wherever */ #define MAX_WORD_SIZE 1024 +static bool debug = FALSE;

Patch: safeguard against too large value for uid being sent to solr for single mailbox searches
by John Fawcett 09 Jan '22

09 Jan '22

Hi I'm reposting a patch for solr integration which I have been applying locally. It applies against 2.3.17.1. Dovecot already has a mechanism when doing solr fts searches on multiple mailboxes that prevents a too large value for maximum rows being sent to solr. #define SOLR_MAX_MULTI_ROWS 100000 (defined and used in plugins/fts-solr/fts-backend-solr.c) However on single mailbox searches Dovecot uses the last uid of the mailbox, which can be too large for solr. My suggested patch is to also limit maximum rows to return on single mailbox searches. Here is the patch: diff -ur dovecot-2.3.17.1-orig/src/plugins/fts-solr/fts-backend-solr.c dovecot-2.3.17.1-new/src/plugins/fts-solr/fts-backend-solr.c --- dovecot-2.3.17.1-orig/src/plugins/fts-solr/fts-backend-solr.c 2021-12-03 12:48:47.000000000 +0100 +++ dovecot-2.3.17.1-new/src/plugins/fts-solr/fts-backend-solr.c 2022-01-09 01:33:23.401341959 +0100 @@ -837,7 +837,7 @@ str = t_str_new(256); str_printfa(str, "wt=xml&fl=uid,score&rows=%u&sort=uid+asc&q=%%7b!lucene+q.op%%3dAND%%7d", - status.uidnext); + I_MIN(status.uidnext,SOLR_MAX_MULTI_ROWS)); prefix_len = str_len(str); if (solr_add_definite_query_args(str, args, and_args)) { John

When I try to log in to my mail server (ubuntu 20.04, Postfix 3.4.13, Dovecot 2.3.7.2) I get a response saying "Source stream returned no data”. At least to me, that's not particularly informative. Is it any more informative to anyone else? Ken

Sv: banning
by Sebastian Nielsen 08 Jan '22

08 Jan '22

I would say, lock accounts to for example IP address, ASN or GeoIP. This can be accomplished simply by a custom login handler, which also checks IP against database. And first time users, and those who change country/ISP/IP have to simply logon to a web interface (where 2FA can be required and also Captcha) and add their IPs/ASNs/Geo's. For a larger user base, I would recommend GeoIP and no web interface, save country of first login to database, and subsequent logins must originate from same country. Users that want to reset have to contact support. If you are a web hotel who only sell service to a specific country at all, lock the ports in firewall to that GeoIP. For smaller user base, like 50-100 users, I would recommend locking to ASN and providing a web interface where multiple ASN can be added. So people syncing from mobile and home can succeed. For very small user base, like 10's of users, just plan lock to IP. By connecting IP to accounts, you greatly reduce the attack surface.

feature-request: make received-header on submission optional or at least drop the ip in it
by dc-ml＠dvl.werbittewas.de 07 Jan '22

07 Jan '22

hi. we're just trying to re-structure a system and want to use dovcots submission-ability. because the github-repository have no entry for any issues at all, we're sending this feature-fequest to this ML. unfortunately there doesn't seem to be any option to drop the received-header at all or at least hide the IP of the user. because the client-ip is covered by GDPR as personal data and so it should never shown to others without a certain reason, we want to hide it, but there's no "submission_add_received_header"-option like for lmtp and it doesn't seem to be any other option to hide this information. maybe this is possible to implement in near future? thanks a lot. best regards d.

Dovecot fixing maildir message size?
by Grant Keller 07 Jan '22

07 Jan '22

We recently updated dovecot from 2.1.17 to 2.3.10. It used to be when we encountered the following error: Jan 6 15:29:20 d.imapd.sonic.net dovecot: imap(momomo): session=aBd2O/LULMu4F6ia Error: Mailbox INBOX: UID=1: read(/var/spool/mail/07/00/momomo/cur/1510707300.12345_0.a.spam,S=1234:2,) failed: Cached message size larger than expected (1234 > 704, box=INBOX, UID=1) (read reason=) Dovecot would fix the size by renaming the file. Now this doesn't appear to be the case. Was there a change in behaviour, or is there an option I need to enable now to have dovecot auto fix this?

Enable push notifications for all users
by Felix Ingram 06 Jan '22

06 Jan '22

Hello all, Is there a way to enable push notifications for all users, rather than having to enable them one by one? My thinking was to set mail_attribute_dict to a static file but I can’t work out what I would need to put in it. (I’ve now realised that that will not allow me to have other attributes to be different per user, but that’s not a real issue with my use case) If a flat file isn’t the answer, then is a SQL dict my best bet? Thanks in advance, Felix

Hi Alex, thanks for your answer, I think this could be related to Dovecot version in use, in our case it is the same: 2.3.4.1 (f79e8e7e4). It could be useful to know if someone can confirm this assumption so we can try an upgrade to the latest version hoping this could solve our issue.

Doveadm auth fails
by Ken Wright 05 Jan '22

I'm still troubleshooting a faulty email server, and got the following results when I tried doveadm: kwright@grace:/etc/dovecot/conf.d$ doveadm auth lookup me(a)mydomain.com Error: auth-master: passdb lookup(me(a)mydomain.com): Auth PASS lookup failed Error: passdb lookup failed for me(a)mydomain.com kwright@grace:/etc/dovecot/conf.d$ doveadm auth test me(a)mydomain.com Password: Error: auth-client: conn unix:/var/run/dovecot/auth-client: connect(/var/run/dovecot/auth-client) failed: Permission denied (euid=1000(kwright) egid=1000(kwright) missing +r perm: /var/run/dovecot/auth-client, dir owned by 0:0 mode=0755) kwright@grace:/etc/dovecot/conf.d$ ls -la /var/run/dovecot/auth-client srw------- 1 dovecot root 0 Jan 4 19:09 /var/run/dovecot/auth-client I see /var/run/dovecot/auth-client only has read and write permissions for the owner and nothing for anyone else. Is this part of my problem? Ken

Here is what solr sends to dovecot, the offending uid in this exmaple is '21' { "responseHeader":{ "status":0, "QTime":1, "params":{ "q":"body:Zeitserver"}}, "response":{"numFound":1,"start":0,"numFoundExact":true,"docs":[ { "uid":[21], "box":["2e60f3054059c95fbf580600eb1947e0"], "user":["oliver.krone(a)snoog.ch"], "id":"21/2e60f3054059c95fbf580600eb1947e0/oliver.krone(a)snoog.ch", "body":[" ...

I've been trying to log into Dovecot without success, and this is what I found in /var/log/mail.log: Jan 3 02:47:33 grace dovecot: auth: Debug: client passdb out: FAIL#0111#011user=me(a)mydomain.com Jan 3 02:47:33 grace dovecot: imap-login: Disconnected (auth failed, 1 attempts in 6 secs): user=<me(a)mydomain.com>, method=PLAIN, rip=192.168.1.1, lip=192.168.1.10, TLS, session=<bgBsu6jUhqzAqAEB> I know I provided the correct password, but I'm still having no joy.
