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.

ssl_min_protocol appears to be ignored?
by Myriam Luce 14 Apr '22

14 Apr '22

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). Am I forgetting something somewhere, or is this an actual bug?

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
by Steve Litt 14 Apr '22

14 Apr '22

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? Thanks, SteveT Steve Litt March 2022 featured book: Making Mental Models: Advanced Edition http://www.troubleshooters.com/mmm

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. Mar 25 10:37:15 mailsrv1 dovecot: imap(doug)<19284><WKcX5gvbRe7AqFhA>: Error: mkdir(/dev/shm/dovecot/doug) failed: Permission denied (euid=1002(doug) egid=100(users) missing +x perm: /dev/shm/dovecot, dir owned by 97:100 mode=0700) dsync(test): Error: mkdir(/dev/shm/dovecot/test) failed: Permission denied (euid=2003(test) egid=100(users) missing +x perm: /dev/shm/dovecot, dir owned by 97:100 mode=0700) I couldn't locate documentation or discussions on how to set the ownership or permissions for /dev/shm/dovecot in the Dovecot configuration files. 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
by Austin Witmer 11 Apr '22

11 Apr '22

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 () "." Virtual.D&APQ-le&AX4-it&AOk- * LSUB () "." Virtual.Pr&AO0-lohy a OK Lsub completed (0.001 + 0.000 secs). --------------------------------------------------------- As one can see, there are only auto-subscribed Virtual mailboxes, the Virtual.Dnes is missing, despite that it is in subscriptions file. The doveconf -n output (can be wrapped): --------------------------------------------------------- # 2.3.13 (89f716dc2): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.13 (cdd19fe3) # OS: Linux

What is the current state of High Availability Dovecot ?

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

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 ? Kind regards, Dave ---- CUT ---- # doveadm -v sync -df -u 'testaccount(a)mydomain.ext' Debug: Loading modules from directory: /usr/lib/dovecot/modules/doveadm 2022-04-06 10:12:17 Debug: Loading

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. When user found in the first userdb «unknown user» event does not appear. Configuration is: userdb { args = /usr/local/etc/dovecot/udb-ldap-personal.conf driver = ldap override_fields = home=/mnt/mboxes/personal/%n } userdb { args = /usr/local/etc/dovecot/udb-ldap-general.conf driver = ldap override_fields = home=/mnt/mboxes/general/%n } Dovecot verision is 2.3.16 (7e2e900c1a). -- Best regards, Anthony Pankov

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
