Create a separated mailbox for archived mails
by Claudio Corvino 22 Oct '21

22 Oct '21

Hi, I have an MTA configured with Postfix that deliver email to an IMAP/LMTP Dovecot server version 2.3.4.1 configured to bind LDAP/AD for users. I would like to configure Dovecot to create another mailbox to archive mails of users to a separated NFS mount. Here is my /dovecot-ldap.conf/: [...] /ldap_version=3// //auth_bind = yes// //dn = XXX// //dnpass = XXX// //scope = subtree// //user_attrs = sAMAccountName=home=/mnt/mail-storage-dev/%$,=uid=501,=gid=501// //pass_attrs = sAMAccountName=user// //user_filter = (&(objectclass=person)(samaccountname=%n))// //pass_filter= (&(objectclass=person)(samaccountname=%n))/ [...] I think I will add another conf file, let's say /dovecot-ldap-archive.conf /using "url" as LDAP/AD filed to distinguish from normal users: [...] /ldap_version=3// //auth_bind = yes// //dn = XXX// //dnpass = XXX// //scope = subtree// //user_attrs = url=home=/mnt/mail-storage-archive/%$,=uid=501,=gid=501// //pass_attrs = url=user// //user_filter = (&(objectclass=person)(url=%n))// //pass_filter= (&(objectclass=person)(url=%n))/ [...] I then added to "test" user a "url" filed into Active Directory named /test-archive//, b/ut it's not working, when I bind Dovecot with: /doveadm user test-archive/ I receive: /field value// //userdb lookup: user test-archive doesn't exist/ With test user it works: /doveadm user test// //field value// //uid 501// //gid 501// //home /mnt/mail-storage-dev/test// //mail maildir:~/Maildir:INDEX=/var/indexes/test/ What I'm doing wrong? Thanks in advance! // -- *Claudio Corvino IT Systems Administrator*

local_name in dovecot for SNI and wildcard
by Alessio Cecchi 20 Oct '21

20 Oct '21

Hi, in dovecot configuration the options "local_name" can support wildcard domain name (es. *.mailserver.com)? This because we have a wildcard SSL certificate and I prefer to specifica a wildcard name instead of single. Is fine this? local_name *.mailserver.com { ssl_cert = </etc/dovecot/ssl/mailserver.com.pem ssl_key = </etc/dovecot/ssl/mailserver.com.key } And local_name can support multiple hostname in the same line? local_name pop.mailserver.com imap.mailserver.com { ssl_cert = </etc/dovecot/ssl/mailserver.com.pem ssl_key = </etc/dovecot/ssl/mailserver.com.key } Thanks -- Alessio Cecchi Postmaster @ http://www.qboxmail.it https://www.linkedin.com/in/alessice

dovecot-lda -> lmtp server ?
by Scott Q. 17 Oct '21

17 Oct '21

I'm stuck with using Qmail which has no LMTP support, and thus I'm using dovecot-lda which has certain drawbacks. Has anyone found a way to direct dovecot-lda to deliver the mail to the LMTP server or any other way for Qmail to deliver the mail to the LMTP server directly ? Thanks!

Broken uidlist when using NFS on newer kernels
by Jeremy Hanmer 15 Oct '21

15 Oct '21

I know this has been reported in the past, but I think I have some useful new information on the problem. After an OS upgrade from Ubuntu Xenial (4.4.0 kernel) to Ubuntu Focal (5.4.0 kernel) and corresponding upgrade from Dovecot 2.2.27 to 2.3.7.2, we've started seeing broken uidlist files to an extent that's making larger mail boxes nearly unusable because the file is constantly being regenerated. I've also used the 2.3.16-2+ubuntu20.04 version distributed from dovecot.org and the behavior is unchanged. The environment consists of NFS mounts from a NetApp device, with a couple dozen MX servers receiving mail and about a hundred IMAP/POP servers. This is the exact error (note the blank after "invalid data"): Error: Mailbox INBOX: Broken file /mnt/morty/morty2/gravest/x15775549/Maildir/dovecot-uidlist line 373: Invalid data: I've been able to trigger the problem rather easily by piping an email to dovecot-lda in a loop and reading the resulting dovecot-uidlist file on a different server. What it shows is that occasionally we're seeing the last line of the file prepended with a number of null bytes equal to the line that's being written (for example, if the entry is "35322 :1633719038.M516419P3623238.pdx1-sub0-mail-mx202,S=2777,W=2832", we'll have it prepended by 69 null bytes). This then breaks the IMAP process' ability to read the file. My first thought was to extend the retry functionality so the imap proces makes more attempts to read the file when it detects a problem like this, but would love input from someone more familiar with the codebase.

email migration of mdbox to sdbox with set index in mail_location
by filipe＠digirati.com.br 13 Oct '21

13 Oct '21

Hello, my name is Filipe I'm migrating an email server to another new server. Accounts have their storage configured as mdbox and their index being saved in another storage device. I want to migrate all messages to the new server with a new storage mode, sdbox. The new server will have storage settings set to sdbox for email accounts: In dovecot's doc it says mdbox mode is the only one that supports index storage on another device. https://doc.dovecot.org/admin_manual/mailbox_formats/dbox/#layout /"Index files can be stored in a different location by using the INDEX parameter in the mail location specification. If the INDEX parameter is specified, it will override the root mail location for index files and the "map index" file (mdbox only). "/ Even with this warning I performed the migration of some accounts as a test. running the commands from server A to server B. "Server A" conf: dovecot version: 2.2.33.2 /mail_location: mdbox:/var/spool/imap/test=x.com:INDEX=/var/lib/imap/user/test=x.com/ "Server B" conf: dovecot version: 2.3.7.2 /mail_location: sdbox:/var/spool/imap/test=x.com:INDEX=/var/lib/imap/user/test=x.com/ command executed on server A to execute message migration: /root@serverA: ~# doveadm sync -u test=x.com ssh root@*serverB* doveadm dsync-server -u test=x.com/ In the end, the message migration was successful and the access to the email account worked normally on server B. The question is whether dovecot has this support to move the index when I use the sdbox? Thank you for your help

Howto show user id for failed authentications attempts
by Jesús Ángel del Pozo 13 Oct '21

13 Oct '21

Hello, I am using dovecot_authenticator for Exim and I get a lot of authentication failure log entries, most of them due to brute force attacks.

two different mail_location
by Gabx 12 Oct '21

12 Oct '21

Hi everybody, my mail system has all users in usual path ~ . Only one user is in /var/%u . This user doesn't receive emails. I guess it is because its $HOME is on a different path than the one specified in dovecot mail_location which is: > mail_location = maildir:~/%u/Maildir What's the best way to solve this issue ? Namespaces ? If so could someone explain me how ? Best Regards Gabriel -- GPG fingerprint: 5A6A F742 ACEA C9A7 93A8 8D5E 7AEF 5A02 D080 89F7 Contact: xmpp://gabx@jabber.tcpreset.net

Dovecot Replica one user at a time
by Claudio Corvino 12 Oct '21

12 Oct '21

Hi all, I have two IMAP/LMTP Dovecot server in replica (version 2.3.4.1) for testing purposes, both connected through an IPsec tunnel, I use LDAP/AD for /userdb, /all seems to work fine. Now I would like to go in production where at the moment I have only one server active and setup the replica too ... but! I need to know how I can exclude all the users from replication (help/examples appreciated!) and doing replication one user at a time, in order to not saturate bandwidth on the IPsec tunnel. I read https://wiki.dovecot.org/Replication: "Since v2.3.1 you can disable replication for a user by providing 'noreplicate' user database field <https://wiki.dovecot.org/UserDatabase/ExtraFields>. Another way to disable replication for some users is to return mail_replica field from userdb for users you want to replicate." but I can't figure out how to do it. One last question: since I have to deal with huge mailboxes, if prior to activate replication I do an rsync between the two Dovecot filesystems, does the replication will work? Thanks in advance! Cheers -- *Claudio Corvino IT Systems Administrator*

Authentication problems due to file ownership issue.
by C. Petro 12 Oct '21

12 Oct '21

I am getting: Oct 03 20:19:52 auth: Error: net_connect_unix(auth-worker) in directory /run/dovecot failed: Permission denied (euid=5000(vmail) egid=5000(vmail) missing +r perm: /run/dovecot/auth-worker, dir owned by 0:0 mode=0755) Because: root@mailserver:/run/dovecot# ls -l auth-worker srw------- 1 dovecot root 0 Oct 3 20:09 auth-worker When it really needs to be "vmail" (I think). I have set: service auth-worker { # Auth worker process is run as root by default, so that it can access # /etc/shadow. If this isn't necessary, the user should be changed to # $default_internal_user. user = vmail group = vmail } in 10-master.conf (because I'm using postfixadmin/mariadb to store user information, I don't *want* access to /etc/shadow) I set this about an hour ago, then applied some security patches and restarted (ubuntu 20.04 system) and it didn't change. I then manually did a "chown vmail: of that file, and I got further. I had a different problem that I resolved, and then restarted dovecot, and /run/dovecot/auth-worker reverted. I'm not sure where I need to set this. Thanks. Petro. :wq

SNI via lookup?
by Felipe Gasper 08 Oct '21

08 Oct '21

Hello, How (if at all) might I configure a Dovecot server to read its SNI configuration dynamically? Right now I’ve got thousands of domains all served from a quite-large static config file that has to be rebuilt every time a domain is added or removed. It would be much simpler if there were a way to make Dovecot call out to some external service to fetch a given domain’s certificate. Thank you in advance! cheers, -Felipe Gasper

writing Maildir subscriptions file outside of dovecot
by David Mandelberg 08 Oct '21

08 Oct '21

Hi, Is it safe to write to the Maildir subscriptions file directly? I'm trying to figure out a way to make sure the subscriptions match the actual folders exactly. I know how to subscribe to existing mailboxes with `doveadm mailbox list` and `doveadm mailbox subscribe`, but the latter seems to only accept mailboxes on the command line, and any local user can see the command line of any other user's commands. Also, that doesn't handle unsubscribing from non-existent mailboxes. I think unsubscribing from any mailboxes listed in `doveadm mailbox list -s` but not in `doveadm mailbox list` would work, but it has the same issue of mailboxes on the command line. It looks like I could do what I want with something like this command, but I'm not sure if it's safe to write directly to the subscriptions file: { echo INBOX; ls -1A | grep '^\.' | cut -c 2-; } > subscriptions (I was also thinking about using `doveadm mailbox list` to write the subscriptions file directly, but it looks like they use different separators and encodings.)

reconsidering my (your?) current setup
by Marc 07 Oct '21

07 Oct '21

With redhat 'dumping' the support for centos and the availability of containers. I thought about reconsidering my default dovecot setup. Since the concept of having a lts distribution that is supported by redhat/centos is more or less 'unavailable'. I thought about using the repo of dovecot with centos8stream. os == For now I stick with centos8stream, just because the rest is still on centos7 support and the ceph development team is using it as a default. (And can't yet let go of the idea this closest to professional distro ;)) auth uid gid os =============== I am not really convinced that storing users in mysql/postgres is a better alternative than having linux do auth. I also think it is good to have mailbox files stored with different uid's (no idea if this is even the case when dovecot is using mysql/maria/postgres) Normally I would use a synced ldap server on the vm for authentication. But I was thinking of using now an external ldap task from the container environment. To de-duplicate services/data and make the environment simple. Since rh is moving to a different ldap server, it would be good to have this seperated in the future. New to me is the sssd, used nscd/nslcd for decades without issues. I guess the best solution is to have the os uid/gid coming from sssd, configure sssd to have a huge timeout if the backend ldap auth is not available. What is your thought about this? auth uid gid dovecot ==================== I do not really have an idea if I should have dovecot use ldap directly or use this sssd pam? The advantage of using ldap directly is you could maybe skip identifying users in the os. But maybe then tools like dovadm that require a user are not working anymore. From the keep it simple perspective it is probably better to use sssd. However centos8stream and sssd are not really known to me. So any ideas/advice about this?

sieve: active= doesn't seem to use bindir=
by David Mandelberg 05 Oct '21

05 Oct '21

Hi, I'm trying to set up dovecot to read sieve source files from a read-only directory, and save compiled binaries to a separate directory with the bindir option. That worked when I pointed the sieve option at a single file, but I just changed it to point at a directory and added the active= option, also pointing at a symlink in a read-only directory. It looks like dovecot is trying to save the compiled active script to the same directory as the source file, instead of to bindir. Am I missing something? $ doveconf -n # 2.3.13 (89f716dc2): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.13 (cdd19fe3) # OS: Linux 5.10.0-8-amd64 x86_64 Debian 11.0 ext4 ... plugin { sieve = file:/usr/local/etc/mail/%{domain}/%{username}/sieve;active=/usr/local/etc/mail/%{domain}/%{username}/sieve/.active.sieve;bindir=/var/cache/mail/%{domain}/%{username}/sieve sieve_before = file:/etc/dovecot/sieve-before sieve_filter_bin_dir = /etc/dovecot/sieve-filter-bin sieve_filter_exec_timeout = 30s sieve_global_extensions = +vnd.dovecot.filter sieve_plugins = sieve_extprograms sieve_user_log = /var/local/mail/persistent/mail/%{domain}/%{username}/sieve.log } ...

Issue with the log service after upgrading from 2.1.17 to 2.3.10.1
by Grant Keller 05 Oct '21

05 Oct '21

Hello, As stated in the subject we have been doing a pretty big version upgrade. Both new and old are on CentOS 7. For the second time, one of our upgraded servers have had the dovecot log process start consuming 100% cpu, and the strace output shows it trying to access /etc/localtime: stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=2819, ...}) = 0 stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=2819, ...}) = 0 stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=2819, ...}) = 0 stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=2819, ...}) = 0 stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=2819, ...}) = 0 stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=2819, ...}) = 0 With no other output then that multiple times a second. The process itself shows this from ps: root 76106 8.3 0.0 15384 6532 ? R Sep29 140:21 dovecot/log [service too fast: 34/34/imap-postlogin: ] As a part of this upgrade we also modified our postlogin script to include an index location for each user, so I am not sure if this is related to that change or a change in the logging service.

I'd seen them around yes, but that would require mounting a local dovecot to make the mailboxes available over IMAP no? And I was kinda hoping to avoid doing that, as as noted in the initial message I know very little about dovecot.

I've seen thread with problem identical to mine started "Fri May 28 13:54:27 EEST 2021" and I was wondering did you get to fix this issue? Mine looks like this: dovecot: replicator: Panic: data stack: Out of memory when allocating 1073741864 bytes dovecot: replicator: Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(backtrace_append+0x42) [0x7f57c5a4c4e2] -> /usr/lib/dovecot/libdovecot.so.0(backtrace_get+0x1e) [0x7f57c5a4c5fe] -> /usr/lib/dovecot/libdovecot.so.0(+0xfc49b) [0x7f57c5a5849b] -> /usr/lib/dovecot/libdovecot.so.0(+0xfc531) [0x7f57c5a58531] -> /usr/lib/dovecot/libdovecot.so.0(+0x53aee) [0x7f57c59afaee] -> /usr/lib/dovecot/libdovecot.so.0(+0x53435) [0x7f57c59af435] -> /usr/lib/dovecot/libdovecot.so.0(+0xf5d88) [0x7f57c5a51d88] -> /usr/lib/dovecot/libdovecot.so.0(+0x11b818) [0x7f57c5a77818] -> /usr/lib/dovecot/libdovecot.so.0(+0xf25f2) [0x7f57c5a4e5f2] -> /usr/lib/dovecot/libdovecot.so.0(+0xf26a9) [0x7f57c5a4e6a9] -> /usr/lib/dovecot/libdovecot.so.0(buffer_write+0x1e) [0x7f57c5a4e8be] -> dovecot/replicator(replicator_queue_push+0x14a) [0x55aabc673b1a] -> dovecot/replicator(+0x5296) [0x55aabc673296] -> dovecot/replicator(+0x493e) [0x55aabc67293e] -> dovecot/replicator(+0x4acc) [0x55aabc672acc] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x69) [0x7f57c5a6df59] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0x132) [0x7f57c5a6f592] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x50) [0x7f57c5a6e000] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x40) [0x7f57c5a6e1c0] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f57c59e44e3] -> dovecot/replicator(main+0x18d) [0x55aabc671cad] -> /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xea) [0x7f57c57b4d0a] -> dovecot/replicator(_start+0x2a) [0x55aabc671d6a] And setting vsz_limit = 0 doesn't help either - it just tries to allocate all available memory.

Exporting a mailbox over IMAP.
by Xavier Morel 04 Oct '21

04 Oct '21

Hello, Upfront note: I know very little about dovecot and IMAP lingo / terms of art, I'll try to be clear and complete but I may be missing important bits. I have a VPS backup with mailboxes in the maildir dovecot format: $ ls some/folder/backup/mail/domain/\* cur dovecot-uidlist dovecot-uidvalidity.5c0637b7 dovecot.index.cache dovecot.mailbox.log subscriptions dovecot-keywords dovecot-uidvalidity dovecot.index dovecot.index.log new tmp Separately and independently, I also have an existing IMAP account I do not personally manage. By "account" I mean that if I connect to the IMAP server, LOGIN, then LIST I see a pretty standard set of folders: (\HasNoChildren) "/" INBOX (\HasNoChildren \Archive) "/" Archive (\HasNoChildren \Drafts) "/" Drafts (\HasNoChildren \XNotes) "/" Notes (\HasNoChildren \Sent) "/" Sent (\HasNoChildren \Junk) "/" Spam (\HasNoChildren \Trash) "/" Trash I would like to copy / upload / … the content of the backup mailboxes to the IMAP account, ideally without losing the metadata. I asked about this on IRC and user "cmouse" provided me with information about the imapc storage (plugin?), a sample "doveadmin import" command, and a sample dovecot configuration which I expanded to this (for simplicity, the original sample command used a lot of `-c` and I figured I could just shove them into the configuration file for readability): $ dovecot -n # 2.3.16 (): /opt/local/etc/dovecot/dovecot.conf # OS: Darwin 15.6.0 x86_64 auth_verbose = yes imapc_host = <server> imapc_password = # hidden, use -P to show it imapc_port = 993 imapc_ssl = imaps imapc_user = <user> mail_location = imapc: # did not setup a "vmail" user or group as I just want to move the contents mail_uid = <current_user> mail_gid = staff namespace { inbox = yes location = prefix = separator = / } ssl = no verbose_proctitle = yes verbose_ssl = yes That did not work as I guess "import" wants to create all the mailboxes, and these already exist: $ doveadm -Dv import maildir:some/folder/backup/mail/domain/\* '.' all […] Debug: Mailbox Archive: Mailbox opened because: import Debug: Mailbox spam: Mailbox opened because: import Debug: Mailbox Junk: Mailbox opened because: import Debug: Mailbox Trash: Mailbox opened because: import Debug: Mailbox Sent: Mailbox opened because: import Debug: Mailbox Drafts: Mailbox opened because: import Debug: Mailbox INBOX.Spam: Mailbox opened because: import Debug: Mailbox INBOX.Junk: Mailbox opened because: import Debug: Mailbox INBOX.Drafts: Mailbox opened because: import Debug: Mailbox INBOX: Mailbox opened because: import Debug: Namespace : Using permissions from : mode=0700 gid=default Error: Couldn't create mailbox ./INBOX: Mailbox already exists I tried messing around with the options but didn't achieve anything, the only change which did anything visible was to replace '.' with '.INBOX' which resulted in import creating `.IMPORT/IMPORT` and exiting with: Error: Couldn't create mailbox INBOX/INBOX: Invalid mailbox name which… fair enough.

Something like that? Anyway that's where I'm stuck so far, I've got no idea whether `sync` is even the right direction but I don't really know what to try. NOTES: the maildir I'm working on right now has 41 messages in it: $ ls some/folder/backup/mail/domain/\*/cur | wc -l 41 though the uidlist has 45 lines (which is 3 more than I'd have expected): $ wc -l some/folder/backup/mail/domain/\*/dovecot-uidlist 45 some/folder/backup/mail/domain/\*/dovecot-uidlist Xavier

ssl_cipher_list
by dovecot＠ptld.com 04 Oct '21

04 Oct '21

Is there a difference between not setting #ssl_cipher_list = or setting to nothing ssl_cipher_list = or setting to ssl_cipher_list = PROFILE=SYSTEM Which is the best preferred way for default? Also, the docs say "You should usually prefer server ciphers and their order, so setting ssl_prefer_server_ciphers=yes is recommended." however this setting is =no by default. Why? Should it be yes or not?
