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 ? 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

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
by Paul Kudla (SCOM.CA Internet) 24 Mar '22

24 Mar '22

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. Use # "postfix reload" to eliminate the delay. # #alias_maps = dbm:/etc/aliases alias_maps = hash:/usr/home/postfix/config/aliases #alias_maps = hash:/etc/aliases, nis:mail.aliases #alias_maps = netinfo:/aliases # The alias_database parameter specifies the alias database(s) that # are built with "newaliases" or "sendmail -bi". This is a separate # configuration parameter, because alias_maps (see above) may specify # tables that are not necessarily all under control by Postfix. # #alias_database = dbm:/etc/aliases #alias_database = dbm:/etc/mail/aliases alias_database = hash:/etc/postfix/aliases #alias_database = hash:/etc/aliases, hash:/opt/majordomo/aliases # ADDRESS EXTENSIONS (e.g., user+foo) # # The recipient_delimiter parameter specifies the separator between # user names and address extensions (user+foo). 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 # :nexthop part is optional.

By default, mail for unknown@$mydestination, # unknown@[$inet_interfaces] or unknown@[$proxy_interfaces] is returned # as undeliverable. # # The following expansions are done on luser_relay: $user (recipient # username), $shell (recipient shell), $home (recipient home directory), # $recipient (full recipient address), $extension (recipient address # extension), $domain (recipient domain), $local (entire recipient # localpart), $recipient_delimiter. Specify ${name?value} or # ${name:value} to expand value only when $name does (does not) exist. # # luser_relay works only for the default Postfix local delivery agent. # # NOTE: if you use this feature for accounts not in the UNIX password # file, then you must specify "local_recipient_maps =" (i.e. empty) in # the main.cf file, otherwise the SMTP server will reject mail for # non-UNIX accounts with "User unknown in local recipient table". # #luser_relay = $user(a)other.host #luser_relay = $local(a)other.host #luser_relay = admin+$local # JUNK MAIL CONTROLS # # The controls listed here are only a very small subset. 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.
