Dovecot Director scaling / performance
by tim＠linux-daus.de 15 Dec '20

15 Dec '20

Hi, currently i'm going to evaluate the Dovecot Director. Are there someone with experience how the Dovecot Director does scale? The last current information i could find was a post on this mailing list from 2012: 4 Directors are well known, >75 are too much. Are there any more up to date experience regarding how many user (current and new/s) a single Dovecot Director/proxy node could handle and how many director nodes in a ring are known to work (well)? Best regards, Tim

Putting UIDL value into X-UIDL: header
by Süleyman Düzdaban 15 Dec '20

15 Dec '20

Hi, Is there any way to put UIDL value into X-UIDL: header with Dovecot or Sieve? As stated in https://wiki2.dovecot.org/Migration page QPopper can do that. I'm asking this for preventing clients who are using POP to re-download messages and making future migrations easy. I can really benefit from inserting UIDL values even only for the new messages from now on, but if there is any way to put it into all messages in all mailboxes (Maildir) I would be grateful for that too. Dovecot version: 2.3.8 (9df20d2db) Thanks in advance.

How to reset / remove all replicator users
by Ralf Becker 14 Dec '20

14 Dec '20

After creating a new replication pair, it was started with an old sqlite userdb, we use for iteration / replication. The situation was quickly resolved by generating a new sqlite userdb, as it is done hourly anyway. Unfortunately I can not get ride of all access users from the replication: / # doveadm replicator status Queued 'sync' requests 0 Queued 'high' requests 0 Queued 'low' requests 0 Queued 'failed' requests 0 Queued 'full resync' requests 14 Waiting 'failed' requests 1 Total number of known users 724 / # doveadm user '*'|wc -l 507 The replication process creates again and again a lot (empty) mailboxes on both sides of the replication. I tried the obvious with no avail: / # doveadm replicator remove '*' Error: Replicator failed: User not found I also tried restarting the pair one after the other, but it seems the users to replicate are somewhere persisted. I'm also trying to delete the users from the newly created (empty) mailboxes, but the number of known users in "doveadm replicator status" is unchanged: root:/var/dovecot/imap# for domain in $(ls -1 |grep -v bb-trunk.egroupware.de|grep -v outdoor-training.de|grep -v rbz-); do for user in $domain/*; do echo "$(basename $user)@$domain"; doveadm replicator remove "$(basename $user)@$domain"; done; rm -rf $domain; done Any idea what else I can do, or where the replication stores it's users?

How to setup Dovecot director in a NAT-like environment?
by Richard Mader 14 Dec '20

14 Dec '20

How can I setup Dovecot director in a NAT like environment? My mailservers are running within docker and one of them behind a router, so the IP that dovecot binds to does not match the IP that other mailservers have to use to connect to them. Since when running director the servers connect to each other, I'd guess I'd have to set the external IP of the servers in the "director_servers". If I do that I'm unable to start the director nodes since they cannnot find out which of the addresses is their own. I had a quick peek at the sourcecode and director detects its own address by trying to bind to all of the addresses. Since we're behind a NAT, that will of course fail for its external IP. When I set the local address or localhost in the "director_servers" directive, then the director nodes are able to start but they are denied when connecting to other nodes. When using the NAT-internal IP I've got the following error: > Error: Remote director thinks it's someone else (connected to > <other-directors-external-ip>:9090, remote says it's > <other-directors-internal-ip>:9090) When using localhost/127.0.0.1 then I get: > Info: Connecting to <other-directors-external-ip>:9090 (as 127.0.0.1): > Alone in director ring - trying to connect to others > Error: connect(<other-directors-external-ip>:9090) failed: Invalid > argument Is it somehow possible to tell director which of the addresses within "director_servers" is its own address, that it then advertises to other servers, instead of trying figuring that out itself by trying to bind to all ip-addresses on startup? Kafka e.g. has the "advertised.listeners" property to set a custom host to announce to clients and to other Kafka nodes. If there is not such a property or any other workaround, I might consider implementing this into director myself. Although I might need some help getting started since this is my first time contributing to a non Scala/Java or Typescript/NodeJS Project. So far I've discovered that Github seems to be the official repo and is not just a mirror and I was able to compile it on my machine. Now I've got questions such as, where can I find the binaries that I've just compiled and whats the best way to get them running locally and to test my changes, where are unit tests located, ...? Best Regards, Richard

Migrate mailbox from NFS folder to new NFS folder
by Claudio Corvino 14 Dec '20

14 Dec '20

Hi everyone, I need to migrate many user mailboxes from an NFS folder to a new NFS folder, both mounted on the same Dovecot server (2.2.27). Once migrated, users will connect to a new Dovecot server (2.3.4.1). I would like to know how to use /doveadm backup/ (or sync?) instead of /rsync/ as I noted that after migration with rsync I have duplicates and some e-mails marked as unread. What is the correct way to achieve this? Thanks Cheers

Unexpected behavior of doveadm mailbox delete -e -s
by Mar Alegre 13 Dec '20

13 Dec '20

Hello, I have encountered what I believe to be a bug, or at least inaccurate documentation. I am running version 2.3.4.1 of Dovecot (installed via the default repo for Debian 10), so my apologies if this has been fixed in a more recent version. I tried to look for changelogs but was not able to find any. The `doveadm mailbox delete` command accepts flags `-e` and `-s` (among others). The flags are described by both the man pages and the wiki as follows: - `-e`: Require mailboxes to be empty before deleting. - `-s`: Unsubscribe deleted mailboxes. Based on these descriptions, I would expect that when both of these flags are combined, a directory that is not empty would be neither deleted nor unsubscribed. However, I have discovered that when I run the command `doveadm mailbox delete -u $myusername -e -s $non_empty_dir`, the result is that the directory is not deleted, but it *is* unsubscribed. I assume this is a bug, but if it is intended, the documentation should probably be updated to more clearly communicate that the `-s` flag will cause a directory to be unsubscribed even if it is not deleted. Best, Mar Alegre

fyi: please change /var/run to /run in debian buster repository
by Michael 12 Dec '20

12 Dec '20

hey, just one minor thing: if there's any time left, please change in the repository debian/buster in the package dovecot-core in the file /lib/systemd/system/dovecot.service the line PIDFile=/var/run/dovecot/master.pid to PIDFile=/run/dovecot/master.pid because systemd always shows the following warning: Dec 12 15:46:30 mail systemd[1]: /lib/systemd/system/dovecot.service:9: PIDFile= references path below legacy directory /var/run/, updating /var/run/dovecot/master.pid → /run/dovecot/master.pid; please update the unit file accordingly. creating a drop-in in /etc/systemd/system/dovecot.service.d/ doesn't do anything. greetings...

Potential issue with lmtp_rawlog_dir when using TLS

Dovecot 2.3.11.3 LMTP dropping connection after first part of multipart message received
by Steve Akerman 11 Dec '20

11 Dec '20

Good afternoon I have been using Dovecot with great success for several months now with one problem: I have received several messages (3 to date out of a much larger number) which cause Dovecot LMTP to drop the connection with sendmail after only receiving the first part of the message. Dovecot saves the first part to INBOX, and then drops the link with sendmail as it sees the rest of the data from sendmail as new (and invalid) commands Sendmail sees the delivery as unsuccessful and requeues the message, so the cycle continues until i kill the queue These messages are all Multipart MIME I have attached an extract from the log which shows the above sequence Finally, I have kept one such message from the sendmail queue (df and qf) should this be useful, but prefer not to post here as not sanitised Any help in correcting my configuration would be appreciated.

Standalone Directors
by William Edwards 11 Dec '20

11 Dec '20

Situation: We will be switching to Dovecot proxy + Director with three email clusters - each cluster will host different email domains and users - with CephFS storage. Problem: A Director instance has one 'director_mail_servers' setting, meaning I could only use one set of email servers, while the set of email servers in the cluster depends on the client's domain. (The reason I use Dovecot proxy is so people can use the same IMAP/POP/SMTP hostnames; regardless of which email server / email cluster they're hosted on.) Question: Is it possible to set 'director_mail_servers' based on the client's email domain? Met vriendelijke groeten, William Edwards

problems after upgrade from 2.2.27 to 2.3.4.1
by Lampa 09 Dec '20

Hello, after debian version from 9 to, also dovecot was upgraded. There was problems with right imap and imap-login connection settings. I adjusted process_limit, service count increased /proc/sys/net/core/somaxconn from 128 to 1024 for imap It's a system with 1000+ imap and 200+ pop3 connections. When imap connections are over 1000 problems begins.

Question about login_log_format_elements in a proxy environment
by Adi Pircalabu 08 Dec '20

08 Dec '20

Hi, I have a Dovecot proxy setup with several proxy machines (currently running 2.3.11.3) in front of the real Dovecot servers (2.3.10.1) storing the mailboxes. "doveconf -a | egrep lip" returns: login_log_format_elements = user=<%u> method=%m rip=%r lip=%l mpid=%e %c session=<%{session}> In the real server maillog I'm expecting to have "lip" replaced with the IP address of the proxy. It works as expected for imap-login processes, however for pop3-login processes I still see the real server IP instead of the proxy IP. Ideas? Regards, -- Adi Pircalabu

dovecot/imap killed with signal 6 after SEARCH in specific mailbox
by Jiri 07 Dec '20

07 Dec '20

Hi All, on my older production server (Deb9 dovecot version 2.2.27-3+deb9u6) a client reported that searching text in one mailbox failed while other mailboxes do search ok. He is using Rouddcube webmail and is searching the whole messages including the body. Errorlog shows panic and assertion failed logs. So I'v moved the 'problematic' mailbox to my latest production server (Deb10 2.3.4.1-5+deb10u4 = 2.3.4.1 (f79e8e7e4)) where I have more RAM to eliminate that and the same error appeared. There is nothing special about the mailbox, roughly 600MiB and 2200 messges. Other much larger mailboxes on the same server do search fine. After turning on imap logging in Roundcube mail, the critical command was: A0004 UID SEARCH RETURN (ALL) TEXT whatever I increased default_process_limit and default_client_limit, I run: doveadm index -u ttt(a)mail2.swpraha.cz -q INBOX but didn't help. I used the gdb method to reproduce it and to get the whole info including backtrace: vmail@s6mail:~$ gdb --args /usr/lib/dovecot/imap -u ttt(a)mail2.swpraha.cz (gdb) r Starting program: /usr/lib/dovecot/imap -u ttt(a)mail2.swpraha.cz process 4458 is executing new program: /usr/bin/doveconf process 4458 is executing new program: /usr/lib/dovecot/imap * 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 LITERAL+ NOTIFY SPECIAL-USE QUOTA] Logged in as ttt(a)mail2.swpraha.cz a select INBOX * FLAGS (\Answered \Flagged \Deleted \Seen \Draft $MDNSent Junk $Forwarded NonJunk) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft $MDNSent Junk $Forwarded NonJunk \*)] Flags permitted. * 682 EXISTS * 0 RECENT * OK [UNSEEN 639] First unseen. * OK [UIDVALIDITY 1147771637] UIDs valid * OK [UIDNEXT 104487] Predicted next UID * OK [HIGHESTMODSEQ 53108] Highest a OK [READ-WRITE] Select completed (0.002 + 0.000 + 0.001 secs).

logging in to postfixadmin failed probably because of a dovecot error
by peacecop kalmer: 07 Dec '20

07 Dec '20

I can’t log in to postfixadmin anymore. It says that the username or password is incorrect. It can’t be incorrect as I’ve stored them in Google and “Chrome”. I have two admin accounts and none of them can’t be used for logging in. So I changed the main password with “setup.php” and copied that hash into the configuration file. Then, I deleted one of the admin accounts directly in the database from the table “admin”. Finally, I tried to recreate that deleted admin account using “setup.php”. I get the following error message: “can’t encrypt password with dovecotpw, see error log for details”. I had a look into the error log file of postfixadmin and found these complaints: [Wed Dec 02 02:33:37.551048 2020] [authz_core:debug] [pid 30540] mod_authz_core.c(809): [client 192.168.1.65:54948] AH01626: authorization result of Require all granted: granted, referer:https://postfixadmin.tennis24.ee/setup.php [Wed Dec 02 02:33:37.551070 2020] [authz_core:debug] [pid 30540] mod_authz_core.c(809): [client 192.168.1.65:54948] AH01626: authorization result of : granted, referer:https://postfixadmin.tennis24.ee/setup.php [Wed Dec 02 02:33:37.551280 2020] [php7:warn] [pid 30540] [client 192.168.1.65:54948] PHP Warning: Cannot assign an empty string to a string offset in /usr/share/postfixadmin/variables.inc.php on line 31, referer:https://postfixadmin.tennis24.ee/setup.php [Wed Dec 02 02:33:37.568128 2020] [php7:notice] [pid 30540] [client 192.168.1.65:54948] dovecotpw password encryption failed., referer:https://postfixadmin.tennis24.ee/setup.php [Wed Dec 02 02:33:37.568155 2020] [php7:notice] [pid 30540] [client 192.168.1.65:54948] STDERR output: doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/10-ssl.conf line 13: ssl_cert: Can't open file /etc/letsencrypt/live/test.tennis24.ee/fullchain.pem: Permission denied\n, referer:https://postfixadmin.tennis24.ee/setup.php [Wed Dec 02 02:33:37.568897 2020] [deflate:debug] [pid 30540] mod_deflate.c(854): [client 192.168.1.65:54948] AH01384: Zlib: Compressed 1320 to 732 : URL /setup.php, referer:https://postfixadmin.tennis24.ee/setup.php Is the issue connected to the permission problem?

http pipelining on auth_policy_server
by Adrian M 07 Dec '20

07 Dec '20

Hi, I'm curious to know if dovecot can be configured to do pipelining for auth_policy in order to use less connection to the server and keep them for longer. I'm working on making a small policy server and the lack of persistent connections is a cause of overhead. Thank you !

[patch] enhancement for adding limits to solr and tika parsing
by John Fawcett 07 Dec '20

07 Dec '20

Hi As mentioned in a previous thread, the solr + tika combination has caused me some issues due to attachment size. While tika seems to be able to parse large attachments, the resulting volume of text can overwhelm the solr server. One solution would be to throw resources at the problem, but in my case such large attachments don't contain anything worthwile indexing. Additionally I don't want people to be able to randomly crash my solr server by sending large compressed attachments that expand into huge volumes for solr. It's also a safety feature to have sane limits on what can be indexed. Attached is a first attempt to address the problem. I did not find a way to easily get actual attachment sizes, so I used an already available information - the overall message size. It may not be ideal but at least introduces limits where none existed. I have introduced two new parameters for the plugin section, for example: plugin { fts_max_size = 2M fts_max_size_tika = 1M } They can be used separately or together. Both sizes refer to the overall message size. The meaning is: fts_max_size - do not parse message bodies if the message size exceeds this value. A value of 0 indicates no limit. If the message body is not parsed, attachments are also not parsed. fts_max_size_tika - do not parse message attachments with tika if the message size exceeds this value. A value of 0 indicates no limit. If using both settings it makes sense to have fts_max_size > fts_max_size_tika, since with a smaller fts_max_size bodies are not indexed including attachments and the fts_max_size_tika will have no effect. The difference (ft_max_size - fts_max_size_tika) places an upper bound on the size of the non attachment body text that will be indexed. However, any attachments over the fts_size will automatically consume this limit and no body text will be indexed for those messages. I've only updated the tika parser not the script parser though the script parser potentially could benefit from this approach. The attached patch also includes the rolled up patch for using basic auth with the tika server and the previous posted patch (not mine) which solves an assert when using solr and tika together. John

quota-status for outgoing mail (Dovecot/Postfix)
by Peter Folta 06 Dec '20

06 Dec '20

[Dovecot version 2.3.11.3 (502c39af9)] Hi all, I’m using Dovecot’s quota-status service to let Postfix check the recipient’s quota before accepting emails following the guide here: https://blog.sys4.de/postfix-dovecot-mailbox-quota-en.html <https://blog.sys4.de/postfix-dovecot-mailbox-quota-en.html>. This works well for inbound emails. I would like to set up something similar for outbound email, i.e. if a user is over quota, they should not be allowed to send new emails. At the moment, the setup is in a bit of an inconsistent state: Users that have exceeded their quota are still able to send outbound emails but saving them in their Sent folder will fail leaving them without a copy. I have tried using Dovecot’s quota-status in Postfix’s smtpd_send_restrictions but didn’t get this to work. A quick look at the Dovecot source code seems to suggest that the quota-status plugin is only checking the recipient address: https://github.com/dovecot/core/blob/master/src/plugins/quota/quota-status.… <https://github.com/dovecot/core/blob/master/src/plugins/quota/quota-status.…> and https://github.com/dovecot/core/blob/master/src/plugins/quota/quota-status.… <https://github.com/dovecot/core/blob/master/src/plugins/quota/quota-status.…>. I suspect it’s not possible to use the quota-status service to control outbound email but thought I’d ask to confirm. I’m wondering if there’s a different way to achieve this? Thanks Peter

Files in tmp directory
by David Morsberger 05 Dec '20

05 Dec '20

I had to restore many thousands of dovecot emails from a crashed Mac Server to a new Ubuntu server. After completing I am noticing a few things that may be okay or may need to be fixed. 1) a couple of mailboxes have a lot (one has 102462) emails in the tmp directory. The files do not have the standard Mairdir++ filename format. An example: 1581262582.M397740P72267.mini.mmpcrofton.com <http://1581262582.m397740p72267.mini.mmpcrofton.com/> (missing the stuff at the end, ,S=,W=:2,S) 2) I see files in the cur directory that do not have the Maildir++ format. An example: 1601287326.V810Ie80087M240104.mmp-mail.mmpcrofton.com:2,S. (do not have the ,S=,W= values and the second value, V810Ie80087M240104, is longer that the other file names) How do I get the emails in (1) out of tmp? Do I need to convert the emails in (2)? David

Combine director and HAProxy for loadbalancig and failover
by Steven Varco 05 Dec '20

05 Dec '20

Hi All I’m trying to achive an active/active cluster with dovecot-director and HAProxy, as the director does not do health checks (loadblancing only) and I want both, loadblancing AND failover, where the latter is far more important to me (loadblancing I would just use as an addon and for curiosity, it is not really need in my setup). However, I’m not sure if this combination can be used that way, as I found almost no documentation on this. What I found is using either directory OR haproxy with dovecot, but not both. So I guess, that the description here is intended to use without the director: https://wiki2.dovecot.org/HAProxy This older list post is basically exaclty, what I’m trying to achive: https://dovecot.org/pipermail/dovecot/2015-July/101487.html Clients --> Load Balancer(HAProxy) --> Dovecot Proxy(DP) --> Dovecot Director(DD) --> MS1 / MS2 As far as I understood, this would require to (statically) set a host= entry for each client which would give another single point of failure? However reading the documentation: https://doc.dovecot.org/configuration_manual/haproxy/ assumes that this setup IS actually possible. Unfortunately it does not describe how dovecot must be setup at this point. So I assume since HAProxy is listening on port 1143 (for IMAP) and dovecot (with directror enabled) is listening on port 143, which is the main entry point for clients. So in this setup dovecot-director should first pass the mail traffic to HAProxy on port 1143 and then HAProxy passes it to the actual imap servers? So how would the dovecot setup on the director servers look like and how on the dovecot imap mail servers? My setup consist of each two machines: loadblancer (with HAProxy and dovecot-director) and dovecot imap servers. Last but not least, I found documentation for „dovemon“, which, if I got that correctly, should replace the external tool „poolmon“: https://doc.dovecot.org/configuration_manual/dovemon/ - However, I could not find out where the configuration YAML file (/etc/dovecot/dovemon.config.yml) should get included in the main dovecot configuration. By default this file would not be included at all and therefore would have no effect… thanks.

Server-side threading
by ohw.giles＠gmail.com 05 Dec '20

05 Dec '20

Hi list, Considering a message A in INBOX, where a reply B is sent and copied to the recipient's SENT folder, and to which a reply-to-reply C is received, again in INBOX, how should the list of threads in INBOX be (ideally) retrieved? Using THREADS=REFS when listing threads in INBOX to avoid matching unrelated threads unfortunately seems to miss the above example because B is only in SENT, not INBOX. REFERENCES allows A to be linked to C, but the sent message is missing from the returned thread. Of course this is by design. When listing messages in a selected mailbox, many modern clients provide the experience of listing the messages grouped by thread, showing all threads where *at least one message in the thread is in the selected mailbox*. IIUC, clients usually build their own indexes to achieve this, which seems wasteful. Does dovecot provide a server-side way to list or search messages and return threaded results in this manner?

doveadm sync return "failed: EOF (version not received)"

Hi, I have 2 dovecot servers, server1.domain.tld and server2.domain.tld and I'm not able to do a simple doveadm backup command between them. Dovecot version 2.3.11.3, on debian buster, (installed from apt) I try to execute this cmd between to of my dovecot servers : doveadm sync -u postmaster(a)domain.tld remote:root@server2.domain.tld and it returns : doveadm(postmaster(a)domain.tld): Debug: remote(/var/run/dovecot/doveadm-server): auth-master: userdb lookup(postmaster(a)domain.tld): Started userdb lookup doveadm(postmaster(a)domain.tld): Debug: remote(/var/run/dovecot/doveadm-server): auth-master: conn unix:/var/run/dovecot/auth-userdb: Connecting doveadm(postmaster(a)domain.tld): Debug: remote(/var/run/dovecot/doveadm-server): auth-master: conn unix:/var/run/dovecot/auth-userdb (pid=118292,uid=0): Client connected (fd=15) doveadm(postmaster(a)domain.tld): Debug: remote(/var/run/dovecot/doveadm-server): auth-master: userdb lookup(postmaster(a)domain.tld): auth USER input: postmaster(a)domain.tld mail=maildir:/mails/2/domain.tld/postmaster/Maildir:INDEX=/var/lib/dovecot/indexes/domain.tld/postmaster@domain.tld home=/mails/2/domain.tld/postmaster quota_rule=*:storage=3145728000b:messages=500k doveadm(postmaster(a)domain.tld): Debug: remote(/var/run/dovecot/doveadm-server): auth-master: userdb lookup(postmaster(a)domain.tld): Finished userdb lookup (username=postmaster(a)domain.tld mail=maildir:/mails/2/domain.tld/postmaster/Maildir:INDEX=/var/lib/dovecot/indexes/domain.tld/postmaster@domain.tld home=/mails/2/domain.tld/postmaster quota_rule=*:storage=3145728000b:messages=500k) doveadm(postmaster(a)domain.tld): Debug: remote(/var/run/dovecot/doveadm-server): Added userdb setting: mail=maildir:/mails/2/domain.tld/postmaster/Maildir:INDEX=/var/lib/dovecot/indexes/domain.tld/postmaster@domain.tld doveadm(postmaster(a)domain.tld): Debug: remote(/var/run/dovecot/doveadm-server): Added userdb setting: plugin/quota_rule=*:storage=3145728000b:messages=500k doveadm(postmaster(a)domain.tld): Debug: remote(/var/run/dovecot/doveadm-server): Effective uid=65534, gid=65534, home=/mails/2/domain.tld/postmaster doveadm(postmaster(a)domain.tld): Debug: remote(/var/run/dovecot/doveadm-server): Quota root: name=Mailbox backend=count args= doveadm(postmaster(a)domain.tld): Debug: remote(/var/run/dovecot/doveadm-server): Quota rule: root=Mailbox mailbox=* bytes=3145728000 messages=512000 doveadm(postmaster(a)domain.tld): Debug: remote(/var/run/dovecot/doveadm-server): Quota grace: root=Mailbox bytes=314572800 (10%) doveadm(postmaster(a)domain.tld): Debug: remote(/var/run/dovecot/doveadm-server): Namespace inbox: type=private, prefix=INBOX., sep=., inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:/mails/2/domain.tld/postmaster/Maildir:INDEX=/var/lib/dovecot/indexes/domain.tld/postmaster@domain.tld doveadm(postmaster(a)domain.tld): Debug: remote(/var/run/dovecot/doveadm-server): maildir++: root=/mails/2/domain.tld/postmaster/Maildir, index=/var/lib/dovecot/indexes/domain.tld/postmaster(a)domain.tld, indexpvt=, control=, inbox=/mails/2/domain.tld/postmaster/Maildir, alt= doveadm(postmaster(a)domain.tld): Debug: remote(/var/run/dovecot/doveadm-server): Namespace : type=private, prefix=, sep=, inbox=no, hidden=yes, list=no, subscriptions=no location=fail::LAYOUT=none doveadm(postmaster(a)domain.tld): Debug: remote(/var/run/dovecot/doveadm-server): none: root=, index=, indexpvt=, control=, inbox=, alt= doveadm(postmaster(a)domain.tld): Debug: remote(/var/run/dovecot/doveadm-server): quota: quota_over_flag check: quota_over_script unset - skipping doveadm(postmaster(a)domain.tld): Debug: remote(/var/run/dovecot/doveadm-server): brain M: Namespace INBOX. has location maildir:/mails/2/domain.tld/postmaster/Maildir:INDEX=/var/lib/dovecot/indexes/domain.tld/postmaster@domain.tld doveadm(postmaster(a)domain.tld): Debug: remote(/var/run/dovecot/doveadm-server): Namespace INBOX.: Using permissions from /mails/2/domain.tld/postmaster/Maildir: mode=0700 gid=default doveadm(postmaster(a)domain.tld): Error: remote(/var/run/dovecot/doveadm-server): read(root(a)server2.domain.tld) failed: EOF (version not received) doveadm(postmaster(a)domain.tld): Debug: remote(/var/run/dovecot/doveadm-server): auth-master: conn unix:/var/run/dovecot/auth-userdb (pid=118292,uid=0): Disconnected: Connection closed (fd=15) On the destination server, I can see that the destination server is well retrieving the user's info in userdb, before saying : server2 dovecot: doveadm: Error: read(<local>) failed: EOF (version not received) I tried to activate verbosity everywhere, but It does not show anything, like : ssh -v -lroot server2.domain.tld doveadm dsync-server -upostmaster(a)domain.tld -U debug1: Authentication succeeded (publickey).
