dsync multiple mailboxes per connection?
by Felipe Gasper 21 May '20

21 May '20

Hello, Is it possible to batch syncs of multiple mailboxes in a single dsync session? We’re transferring users between servers and want to use dsync to transfer the mail; ideally we’d like to avoid creating a separate TCP connection per user. Thank you! cheers, -Felipe Gasper

how to automatically delete folders from Trash after x days
by chayes＠afo.net 20 May '20

20 May '20

This works great for keeping the Trash from overflowing ... doveadm expunge -A mailbox Trash before 30d ... but it doesn't delete folders that the user put in the trash. What is the recommended method for erasing folders from the trash?

question about director_mail_servers setting
by Joe Wong 20 May '20

20 May '20

Hello, I have a question about director_mail_servers setting for director, I am aware that I can define a list of dovecot backend hostname there but I am not sure if the hashing apply to the hostname or underlying IP address of each hostname given? What if the IP of a specify hostname is changed? Will director pickup the new IP automatically? Will the same user hashed into the original IP still be mapped back to the new IP in this case? - Joe

Problem with tika
by Arjen Heidinga 19 May '20

19 May '20

Hello all, For some time now we've bin using solr as a search engine (working great). I have added tika for searching inside documents, however it keeps crashing when indexing. When just indexing mails that arrive works good, but a reindex on all mail constantly crashes with below stacktrace. When I observe the packets with wireshark I see a HTTP-flow going to tika and suddenly, midway a document dovecot (or the server) sends a RST. Sometimes after thousands of documents, sometimes after a few. Usually after a few hundred. It appears there are less errors using http than https. Relevant config: OS: CentOS6, fully updated plugin { fts = solr batch_size = 1 fts_solr = url=https://username:password@solr-01.vevida.net:443/solr/dovecot/ #fts_tika = https://solr-01.vevida.net:443/tika/ batch_size = 1000 fts_autoindex=yes soft_commit=no } # dovecot --version 2.3.9.3 (9f41b88fa) # Configure options: --docdir=%{_docdir}/dovecot \ --disable-static \ --with-nss \ --with-shadow \ --with-pam \ --with-gssapi=plugin \ --with-ldap=plugin \ --with-sql=plugin \ --with-pgsql \ --with-sqlite \ --with-zlib \ --with-bzlib \ --with-lzma \ --with-libcap \ --with-ssl=openssl \ --with-ssldir=%{ssldir} \ --with-solr \ --with-docs # It is compiled agains the latest openssl # Tika and Solr: Both latest versions. #Stacktrace: doveadm(info(a)samenmetrenske.nl): Info: Sent: Caching mails seq=1..161 doveadm(info(a)samenmetrenske.nl): Panic: file http-client-request.c: line 1173 (http_client_request_send_more): assertion failed: (req->payload_input != NULL) doveadm(info(a)xxxxxxxxxxxxxxxxxxx.x): Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0(backtrace_append+0x2f) [0x7f95d805acbf] -> /usr/lib64/dovecot/libdovecot.so.0(backtrace_get+0x26) [0x7f95d805add6] -> /usr/lib64/dovecot/libdovecot.so.0(+0xe90ba) [0x7f95d80660ba] -> /usr/lib64/dovecot/libdovecot.so.0(+0xe9161) [0x7f95d8066161] -> /usr/lib64/dovecot/libdovecot.so.0(+0x41158) [0x7f95d7fbe158] -> /usr/lib64/dovecot/libdovecot.so.0(http_client_request_send_more+0x424) [0x7f95d8005094] -> /usr/lib64/dovecot/libdovecot.so.0(http_client_connection_output+0x11a) [0x7f95d800a24a] -> /usr/lib64/dovecot/libssl_iostream_openssl.so(+0x8f6a) [0x7f95d57a2f6a] -> /usr/lib64/dovecot/libdovecot.so.0(+0x114483) [0x7f95d8091483] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_call_io+0x61) [0x7f95d807e581] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0xdc) [0x7f95d808076c] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run+0x5c) [0x7f95d807e67c] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7f95d807e8c8] -> /usr/lib64/dovecot/libdovecot.so.0(+0x89105) [0x7f95d8006105] -> /usr/lib64/dovecot/libdovecot.so.0(http_client_request_send_payload+0x1f) [0x7f95d80063cf] -> /usr/lib64/dovecot/lib20_fts_plugin.so(+0xd31d) [0x7f95d6ad931d] -> /usr/lib64/dovecot/lib20_fts_plugin.so(fts_parser_more+0x1a) [0x7f95d6ad83ca] -> /usr/lib64/dovecot/lib20_fts_plugin.so(fts_build_mail+0x761) [0x7f95d6ad6401] -> /usr/lib64/dovecot/lib20_fts_plugin.so(+0x114ca) [0x7f95d6add4ca] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mail_precache+0x2a) [0x7f95d835ab4a] -> doveadm(+0x31e75) [0x55e7c1052e75] -> doveadm(+0x321fb) [0x55e7c10531fb] -> doveadm(+0x2c321) [0x55e7c104d321] -> doveadm(+0x2c577) [0x55e7c104d577] -> doveadm(doveadm_cmd_ver2_to_mail_cmd_wrapper+0x1e8) [0x55e7c104ec38] -> doveadm(doveadm_cmd_run_ver2+0x52e) [0x55e7c105fafe] -> doveadm(doveadm_cmd_try_run_ver2+0x37) [0x55e7c105fb97] -> doveadm(main+0x21a) [0x55e7c1062aca] -> /lib64/libc.so.6(__libc_start_main+0x100) [0x7f95d7983d20] -> doveadm(+0x1c479) [0x55e7c103d479]

doveadm backup, question
by dovecot-user 19 May '20

19 May '20

Hello everyone. I am an inexperienced user of dovecot and I faced probably a simple problem, but I still do not understand how to solve it. The issue is related to using doveadm backup - I want to backup mailboxes; make this copy on the same machine (hereinafter, files with backup copies will be taken from this machine into the storage by a separate mechanism, this is not related to the issue). I am using dovecot 2.2.27 (c0f36b0) on Debian GNU/Linux 9 (stretch). The options related to storing mail and attachments are as follows: mail_location = mdbox:/var/mail/%d/%n mail_attachment_dir = /var/mail/%d/%n/attach Thus, the mail of user(a)domain.tld is stored in /var/mail/domain.tld/user/, and mail attachments inside this directory, for example: /var/mail/domain.tld/user/attach. When I start copying (as root while in test mode): #doveadm backup -u "user(a)domain.tld" sdbox:/backup/domain.tld/user, copying passes, but, as I understand it, the attachments are not copied (I am judging so far by the volume of the initial storage and the received one, it should not differ VERY much, but it differs by 10 times, it seems that it’s just the total amount of attachments). Tell me, plz, how to run doveadm backup correctly so that everything is copied so that you can subsequently deploy it from the backup? Thanks.

dovecot sync not pushing automatically ?
by Laura Smith 17 May '20

17 May '20

Hi, I'm aware its an async process, but despite sending test messages and then waiting a few minutes, the stats are still unchanged : $ sudo doveadm replicator status Queued 'sync' requests 0 Queued 'high' requests 0 Queued 'low' requests 0 Queued 'failed' requests 0 Queued 'full resync' requests 0 Waiting 'failed' requests 0 Total number of known users 18 However if I manually run it using : sudo doveadm -D sync -u test(a)example.com -1 -d -N -l 30 -U It syncs fine and the mails are visible on the standby server. The master server is setup as per the docs : replication_dsync_parameters = -1 -d -N -l 30 -U plugin { mail_replica = tcps:foobar.example.com:11867 } service replicator { process_min_avail = 1 } service aggregator { fifo_listener replication-notify-fifo { user = foobar } unix_listener replication-notify { user = foobar } } service replicator { unix_listener replicator-doveadm { mode = 0600 user = foobar } } replication_max_conns = 10

iterate_query with static userdb ?
by Laura Smith 17 May '20

17 May '20

Hi, Going by the "static userdb" example on this page (https://wiki.dovecot.org/VirtualUsers#homedirs) tried to achieve a similar setup in conjunction with pgsql for passdb. However I get an error "auth: Warning: sql: Ignoring changed iterate_query in /etc/dovecot/local_sql_users.conf, because userdb sql not used. (If this is intentional, set userdb_warning_disable=yes)" Does this mean the following is not a valid config ? Or at least I will not be able to achieve iteration ? mail_location = maildir:/foobar/mail/%d/%n/Maildir passdb { driver = sql args = /etc/dovecot/local_sql_users.conf } userdb { driver = static args = uid=foo gid=bar home=/foobar/mail/%d/%n }

Fallback driver after autodection
by Bjoern Koenig 16 May '20

16 May '20

Dear developers and dovecot users, I am running a dovecot with virtual users that have a mailbox using the Maildir format. mail_location = maildir:/usr/local/virtual/%d/%n New mailboxes are created on-the-fly if a new user logs in. I had the wish that the mailboxes of new users are created using the sdbox format and old mailboxes remain in Maildir format. In case the Maildir and sdbox mailboxes already exist, it is easy to use the "auto" driver which detects the correct format. But it is not possible to create mailboxes with the "auto" driver because there is no way to tell dovecot the preferred mailbox format. I wrote some lines of code which add the possibility to specify a fallback driver that will be used if a mailbox is created with the "auto" driver. mail_location = auto:/usr/local/virtual/%d/%n:FALLBACK=sdbox In case you like the idea you might want to develop it further. I am aware of the fact that there are some caveats if you mix it with other settings like LAYOUT. It won't work in any case.

converting old uucp buffer files to maildir
by mh＠mike.franken.de 15 May '20

15 May '20

Hi *, besides my dovecot maildir structure, that has been migrated from an Exchange server, I have an even older mail structure in an ancient uucp style. The program named CrossPoint I used for this isn't wideley known, but it used so called mpuffer files in a plain text format. It is the program I still use to write for example this mail. I wonder if there already exists a program or script to convert the files from this program to the Dovecot maildir structure or some Howto for writing it myself. The format of these files looks like shown below. Mails are separated by two new lines. ------------------------< snip snip snip >----------------------------- EMP: /archiv/net/dovecot^M KOP: <some_recipient>^M OEM: dovecot(a)dovecot.org^M ABS: ricardomachini(a)gmail.com (Ricardo Machini Barbosa)^M WAB: dovecot-bounces(a)dovecot.org^M BET: Header search on Dovecot with SOLR^M ROT: perth.mydomain.de!localhost!perth.hirmke.de!aqua.hirmke.de!elvis.otherdomain.de!rachael.otherdomain.de!talvi.dovecot.org!talvi.dovecot.org!mail-qk1-x72e.google.com!smtp.gmail.com!DESKTOP4CIJMB3^M MID: 078901d61d7e$0964bcd0$1c2e3670$(a)gmail.com^M EDA: 20200428165659W-03^M LEN: 6112^M MAILER: Microsoft Outlook 16.0^M X-XP-Boundary: ----=_NextPart_000_078A_01D61D64.E4184820^M MIME-Type: multipart/alternative;

doveadm sync backup from old to new server
by Gregory Sloop 15 May '20

15 May '20

So I've done quite a lot of searching on the list and on the web - and perhaps my google-fu is really bad - but I can't find any real recipes on how to sync mail from the old server to the new. As an FYI - the old server is a CPanel/WHM setup on a VPS. The new is mailcow - which uses docker. However, I don't think either of these platforms is what's causing the issue - but I'm certainly not sure of that. --- I've tried several things - but have lost track of all the things I've tried. This seemed like the best of all the things I've tried. This particular mailbox/user+domain is setup on both servers. doveadm backup -D -u mc-user(a)abc.net ssh root(a)abc.net -p2200 doveadm dsync-server -u cp-user(a)abc.net mc-user(a)abc.net is the MC/NEW mailbox/domain cp-user(a)abc.net is the CPanel/OLD user/domain account The SSH server of the remote system is running on port 2200. However when I try this, I get: WARNING: The WATCHDOG_NOTIFY_EMAIL variable is not set. Defaulting to a blank string. dsync-local(user(a)abc.net)<v44NFyRWvF5efgAAb6OASA>: Error: read(remote) failed: EOF (version not received) doveadm(user(a)abc.net): Fatal: execvp(ssh) failed: No such file or directory The process appears to hang, and a Ctrl+C stops it. I'd love to get pointed at a reasonable recipe on how to make this work. I don't really get/understand the docs much at all. [And either everyone else understands it just fine, and never thinks to write a document on how to do it - or, and I think this is a lot more likely - they're using something like imapsync to do it. I found numerous places where others were, essentially, "Dovecot's tool is way too complicated and I can't get it to work right, so I used imapsync." I suppose I should probably just do that too, but it does seem a shame to do that when the dovecot tool is almost certainly the best tool for the job, but I can't figure out how to use it.] If someone can help me grok what's going on, I'm glad to write it up for the list and or a blog entry so it's more accessible. TIA -Greg

Can't connect to Managesieve Server - what´s wrong?
by Anton Blau 15 May '20

15 May '20

Hi, please excuse my bad english language. But I am not a native speaker. I have installed dovecot including sieve and managesieve on a ubuntu 18.04 lts. When I try to access the filter with roundcube (from another vm) I get the error message "Cannot connect to Managesieve-Server". If I try a "telnet myserver.dynvpn.de 4190" from the roundcube-vm I get Trying 188.194.95.63... Connected to myserver.dynvpn.de. Escape character is '^]'.

[Dovecot v2.3.9.3] HTTP API Endpoint for mailbox cryptokey operations
by Thibault HUTTIN-PASSERON 14 May '20

14 May '20

Hello everyone, I successfully set up the mail_crypt plugin using folder keys, and require user's key to be encrypted with a password using mail_crypt_require_encrypted_user_key = yes. As I'm trying to streamline the process of creating a user, and want to develop an application in PHP to help me in that process, I'm very interested in the doveadm HTTP API. Although the mail_crypt plugin is not referenced in the API, I discovered that it could be accessed all the same, provided some camelCase changes. So far I've been able to generate the following json for the mailbox cryptokey generate command: curl -X POST -H "Authorization: X-Dovecot-API <base64-api-token>" -H "Content-Type: application/json" -d '[["mailboxCryptokeyGenerate",{"user":"<username>","userKeyOnly":true},"tag1"]]' http://localhost:8081/doveadm/v1 which is able to give me the same output as the related command: doveadm mailbox cryptokey generate -u <username> -U. This only works if a keypair has already been generated for the user, which is kind of counter-productive in my use case. I would like to know if there was a way to adapt the following command into a json API call : doveadm -o plugin/mail_crypt_private_password=<password> mailbox cryptokey generate -u <username> -U Especially the -o plugin/mail_crypt_private_password=<password> part, since it seems I've figured out the other part partly tinkering partly looking through the source code. Thanks everyone for your input.

Deleting messages from filesystem with sdbox mail format
by Gionatan Danti 11 May '20

11 May '20

Dear list, I recently had to delete some messages from an sdbox mailbox, for which I used the canonical "doveadm expunge" command without issues. However I got curious and, on a test mailbox, I deleted an unimportant message directly from the filesystem (rm u.650). After removing the file, the webmail continued to show it in the mail list - but no text was retrieved when I selected it. I supposed this was due to dovecot.index.cache and, indeed, deleting the cache got rid of the message in the webmail list. While I understand that it is not recommended (deleting and regenerating the index cache is an expensive operation), I wonder if removing a file from the filesystem, and regenerating the index cache file, is a safe operation when using an sdbox mailstore. Specifically, I would like to know if, after a manual filesystem deletion, the main index file (dovecot.index) is automatically updated by dovecot (reflecting the deletion) or if lingering references are kept in it. Thanks. -- Danti Gionatan Supporto Tecnico Assyoma S.r.l. - www.assyoma.it [1] email: g.danti(a)assyoma.it - info(a)assyoma.it GPG public key ID: FF5F32A8

Directory hashing

Hi, I struggle with directory hashing. I want something like this: /srv/mail/c/cf37a8dff5e360927ba10ab2 The final folder is simpel, as it is: %{sha256;truncate=96:user} But how do I get a first level from sha256? Unfortunately, the truncate option aligns only full 8bit and does not divide into low and high nibbles. How can I express this for sha256? in MD5 this would be %1Mu Many thanks in advance Christian -- Rößner-Network-Solutions Karl-Bröger-Str. 10, 36304 Alsfeld Fax: +49 6631 78823409, Mobil: +49 171 9905345 USt-IdNr.: DE225643613, https://roessner.website PGP fingerprint: 658D 1342 B762 F484 2DDF 1E88 38A5 4346 D727 94E5

Unable to disable TLSv1.3 or fallback to TLSv1.2 when 1 cipher is disabled
by Steve Egbert 10 May '20

10 May '20

I have an operational need to disable TLSv1.3 due to inadequate support to exclude certain ciphers. Much to my dismay, the `ssl_protocols` had been renamed and re-functionalized into `ssl_min_protocol`. Now, there is no way to exclude a specific group of one or more TLS versions. For a new bug report, I think we need two new settings: * `ssl_tls13_ciphersuite` and * `ssl_tls10_cipher` settings introduced into Dovecot for better granularity. ALong with support for fallback to TLSv1.2 as outlined in https://bugzilla.mozilla.org/show_bug.cgi?id=1250568 I'm still being hammered with the following error with Thunderbird 76.0b3, Dovecot 2.3.4.1-5+deb10u1, Debian 11: May 8 11:15:47 ns1 dovecot: imap-login: Debug: SSL: where=0x10, ret=1: before SSL initialization May 8 11:15:47 ns1 dovecot: imap-login: Debug: SSL: where=0x2001, ret=1: before SSL initialization May 8 11:15:47 ns1 dovecot: imap-login: Debug: SSL: where=0x2002, ret=-1: before SSL initialization May 8 11:15:47 ns1 dovecot: imap-login: Debug: SSL: where=0x2001, ret=1: before SSL initialization May 8 11:15:47 ns1 dovecot: imap-login: Debug: SSL alert: where=0x4008, ret=582: fatal protocol version May 8 11:15:47 ns1 dovecot: imap-login: Debug: SSL: where=0x2002, ret=-1: error May 8 11:15:47 ns1 dovecot: imap-login: Debug: SSL error: SSL_accept() failed: error:14209102:SSL routines:tls_early_post_process_client_hello:unsupported protocol May 8 11:15:47 ns1 dovecot: imap-login: Disconnected (disconnected before auth was ready, waited 0 secs): user=<>, rip=XX.XX.XX.XX, lip=XX.XX.XX.XX, TLS handshaking: SSL_accept() failed: error:14209102:SSL routines:tls_early_post_process_client_hello:unsupported protocol, session=<GN/GeCSlYuhEhl2U> May 8 11:15:47 ns1 dovecot: imap-login: Debug: SSL error: SSL_accept() syscall failed: Invalid argument This occurred when specifying one TLSv1.3 cipher to be excluded in ssl_cipher via an exclamation mark.

Marking all emails in "Trash" as opened, and also prohibiting email clients from creating new mails
by Sebastian Nielsen 10 May '20

10 May '20

Dovecot version: 2.3.7.2 (3c910f64b) (pkg shipped by: Ubuntu-Desktop 20.04) I want to accomplish 2 things in dovecot: 1: I want to force all mails inside Trash to have an "opened"/"read" flag and "Non-Recent" flag. Basically Status: RO This regardless how the flag appears, either by copying/moving the mail into trash, creating a new mail in trash, flagging email in Trash or whatever. Basically, no email in Trash should ever be able to have a recent or unread flag. I tried with a static mail filter and sieve filter to add \\seen to the email upon COPY (as mentioned here: https://dovecot.org/pipermail/dovecot/2017-November/110122.html ), but regardless how I do it, it doesn't work when Samsung Email client trashes an unread email, AND/OR also, it causes weird issues like duplicate email in the trash folder sometimes. Best would be some event filter that executes for every mail that somehow end up in Trash, that checks if \\seen is present, if not, then it will add it, on all emails in trash? But how I do to prevent the duplicate copy that appears sometimes? 2: I want to prohibit email clients from ever creating a new mail in Sent folder. If its possible to allow MOVE and/or COPY, it should be allowed, only new mail should be prohibited. (also note that external processes must be able to create new mail in Sent) HOWEVER - this prohibition must be silent - ergo the newly created email is simply discarded. No error message or error codes should be returned to IMAP client. (The reason I want this, is because I have configured my outgoing SMTP server to populate Sent, and some email clients doesn't have the option to "Don't store a copy of the email in Sent folder" resulting in duplicates) Best regards, Sebastian Nielsen

Dovecot v2.3.4.1 Debian 10.3 mbox format - Error: chdir(/var/spool/mail/domain/user) failed: Not a directory
by vik 10 May '20

10 May '20

Hi colleagues, I am trying to setup dovecot and have a strange problem. I configured it to: #dovecot -n|grep ^mail mail_gid = mail mail_location = mbox:/var/spool/mail/%d/mailboxes/%n:INBOX=/var/spool/mail/%d/%n mail_uid = mail And also setup exim4 to use it. I sent a test message and observe a mailbox file /var/spool/mail/domain/user, containing this message. But when I try to access dovecot with a client (thunderbird), client cannot fetch mail, and I observe error in the dovecot's log: May 09 23:35:51 imap(user@domain)<25179><JNFIDz2ldeOsEAE3>: Error: chdir(/var/spool/mail/domain/user) failed: Not a directory What is it, and how to solve it? Thank you. Kind regards, Viktor

What's a Reasonable Inbox Size?
by Asai 09 May '20

09 May '20

Greetings, I have several users who have inboxes that are over 20 GB. Lately I have noticed Dovecot logs say it's taking over 30 seconds to sync their mailboxes. As email admins, how do you handle inboxes that are so large? Do you use mailbox types that have better performance like dbox? We're using maildir. What's a reasonable inbox size? Is 20+ GB reasonable and nothing to worry about? Thanks for any insight here. -- Asai7

dovecot-lda quota warning email add BCC
by Admin Beckspaced 08 May '20

08 May '20

Dear dovecot users, I have setup doveot with quota warning. Once a quota wearning is reached a shell script is called which then sends an email to the user via dovecot LDA this is the command in the shell script: /usr/lib/dovecot/dovecot-lda -d $USER -o "plugin/quota=dict:User quota::noenforcing:proxy::quota" I already have looked in the docs: https://wiki.dovecot.org/LDA but can't find an option to add a BCC I would like to receive a copy of the quota warning email so I also get notified and know if user mailboxes get filled up. How could I achieve that? thanks & greetings Becki

courier-dovecot-migrate.pl and courier-5: UTF-8 flag

08 May '20

Hi, Courier to dovecot migration script https://dovecot.org/tools/courier-dovecot-migrate.pl referenced at the https://wiki.dovecot.org/Migration/Courier page has a couple of problems. One of them is that the script could not process courierpop3dsizelist generated by courier-5. File format has been changed a bit to mark UTF-8 messages with an additional attribute. Is it safe to ignore such flag or its value should be stored somewhere for dovecot? Internally courier assumes false value during migration from the previous format version (v2 to v3). --- courier-dovecot-migrate.pl.orig 2012-07-28 17:14:20.000000000 +0000 +++ courier-dovecot-migrate.pl 2020-05-08 09:54:53.249214022 +0000 @@ -170,8 +170,9 @@ my $pop3_fname = "$dir/$courier_pop3_uidfile"; open( $f, $pop3_fname ) || die $!; my $pop3_hdr = <$f>; - if ( $pop3_hdr =~ /^\/2 (\d+) (\d+)$/ ) { + if ( $pop3_hdr =~ /^\/[23] (\d+) (\d+)$/ ) { # /2 <next uid> <uidvalidity> + # /3 <next uid> <uidvalidity> $_ = <$f>; } elsif ( $pop3_hdr =~ /^\/1 (\d+)$/ ) { @@ -193,9 +194,13 @@ chomp $_; $line++; - my ( $full_fname, $fsize, $uid, $uidv ); + my ( $full_fname, $fsize, $uid, $uidv, $_is_utf8 ); - if ( /^([^ ]+) (\d+) (\d+):(\d+)$/ ) { + if ( /^([^ ]+) (\d+) (\d+):(\d+):(\d+)$/ ) { + # v3 + ( $full_fname, $fsize, $uid, $uidv, $_is_utf8 ) = ( $1, $2, $3, $4, $5 ); + } + elsif ( /^([^ ]+) (\d+) (\d+):(\d+)$/ ) { # v2 ( $full_fname, $fsize, $uid, $uidv ) = ( $1, $2, $3, $4 ); }

Seive + Spamprobe terminates with signal 6

Ubuntu 20.04, Dovecot 2.3.7.2, SpamProbe v1.4d. For the past weeks my sieve filters that call spamprobe have been crashing out for some users.

auto: mdbox is automatically recognized as sdbox

Hi:   I did a simple test with Dovecot-2.3.9:            First step : A test account uses mdbox format to store emails with 'mail_location = mdbox:%h/%Ld/%Ln:ALT=%h/altstorage/%Ld/%Ln',           Second step: I adjust 'mail_location = auto:'  and dovecot restart           Third step: telnet 127.0.0.1 143  then log in and fetch emails.     When I fetch email data , the log shows that the storage format is automatically recognized as sdbox and index is Rebuild, as the result, all emails is lost： May 08 12:22:15 mail imap(q2(a)a.com)<30883><+nFkVxul5oF/AAAB>: Debug: Mailbox INBOX: Mailbox opened because: SELECT May 08 12:22:15 mail imap(q2(a)a.com)<30883><+nFkVxul5oF/AAAB>: Warning: sdbox /srv/vmail/a.com/q2/mailboxes/INBOX/dbox-Mails: Rebuilding index May 08 12:23:12 mail auth-worker(30882): Debug: conn unix:auth-worker (pid=29526,uid=12348): Disconnected: Connection closed (fd=-1) May 08 12:24:19 mail imap(q2(a)a.com)<30883><+nFkVxul5oF/AAAB>: Info: Logged out in=50 out=881 deleted=0 expunged=0 trashed=0 hdr_count=0 hdr_bytes=0 body_count=0 body_bytes=0          I am confused why mdbox and sdbox cannot be recognized automatically or there are same problem with my test ??   Thanks

SPECIAL-USE and Outlook folders

Hi, in the recent version of Outlook seem impossible to remap the Sent (but also Drafts) folders in order to show as the localized name. I have enabled the "special_use" in 10-mailbox.conf but still is not working: namespace inbox { inbox = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Sent { auto = subscribe special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Spam { auto = subscribe special_use = \Junk } mailbox Trash { auto = subscribe special_use = \Trash } prefix = separator = / } On Internet someone suggest to add the imap_capability "XLIST" but I haven't understand if it the solutions. Does anyone have any suggestions? Thanks -- Alessio Cecchi Postmaster @ http://www.qboxmail.it https://www.linkedin.com/in/alessice

Unable to set ssl_min_protocol=TLSv1.3
by Thomas Schneider 07 May '20

07 May '20

Good $daytime, as per the recommendations of Mozilla’s SSL config generator[0], I wanted to set ssl_min_protocol=TLSv1.3 in my dovecot config. This produced the error: imap-login: Error: Failed to initialize SSL server context: Unknown ssl_min_protocol setting 'TLSv1.3' After some digging, I found the function that parses this setting in src/lib-ssl-iostream/iostream-openssl-common.c (openssl_min_protocol_to_options()), which maps strings such as SSL_TXT_TLSV1_2 == "TLSv1.2" (from openssl/ssl.h) to the appropriate version and option defines of OpenSSL. Said openssl/ssl.h does not contain a SSL_TXT_TLSV1_3, so it’s no surprise that dovecot does not know this setting. As a quick fix, I could probably extend struct {…} protocol_versions[] (in iostream-openssl-common.c again) with an appropriate "TLSv1.3" entry (and send a patch), though I would also suggest to OpenSSL to add a SSL_TXT_TLSV1_3 define. Unfortunately, I have not found a config setting in dovecot to set SSL_OP_NO_TLSv1_2, or in fact any way to enforce TLS >=1.3, except maybe via the cipher list string. I think that dovecot should support setting this, and I’d also gladly provide a patch. Thanks, Thomas [0]: https://ssl-config.mozilla.org/#server=dovecot&version=2.3.4.1&config=moder…

Hi All, I am having dovecot installed on my redhat 7. There was an email came to my "Maildir" directory as per the logs. There is an application reading the emails from the Maildir inbox. I have the log stating the email has been delivered to maildir folder below. But the application team says that they didn't receive the email. The emails is also not there in the Maildir folder. Is there any way/log we can see, from Maildir folder, whether the application picked the email? or where that email went (to any server) from the Maildir folder? any such verification is possible? ============= [root@testserver log]# grep EB6A2206818 temp.log May 5 07:35:20 testserver postfix/smtpd[29839]: EB6A2206818: client=test-server May 5 07:35:20 testserver postfix/cleanup[29842]: EB6A2206818: message-id=<AM0PR01MB42257878E93ED4C6> May 5 07:35:21 testserver postfix/qmgr[29801]: EB6A2206818: from=< tester1(a)testing.com>, size=13614, nrcpt=1 (queue active) May 5 07:35:21 testserver postfix/virtual[29843]: EB6A2206818: to=< selfemail(a)testing2.com>, relay=virtual, delay=0.05, delays=0.05/0/0/0, dsn=2.0.0, status=sent (delivered to maildir) May 5 07:35:21 testserver postfix/qmgr[29801]: EB6A2206818: removed ============== Please help me...

Thank you for the reply. Actually there are 7 emails sent by the user. 2 emails are delivered successfully. 5 are missing. All are having the same log with virtual. At present I might not be able to change those settings.... Is there any way to verify they are delivered to them or not? do we have any logs to verify the same?

Dovecot IMAPS : Thunderbird SSL cert issue / Evolution OK
by hanasaki＠gmail.com 05 May '20

05 May '20

Recently thunderbird and Dovecot IMAPS cannot agree on SSL however Evolution, on the exact same system, is working fine with the same accounts. Tried recreating the Dovecot cert and also the thunderbird accounts from scratch. The OpenSSL raw client works fine as well. Would someone also confirm the openssl commands to create a selfsigned cert for dovecot imaps. They cert created does work with evolution; just not thunderbird. Thoughts?

Greetings, Lately I've been seeing this error pop up when running a nightly cron to a backup share with doveadm: Error: stat(/vmail/domain.tld/user/.dovecot-box-sync.lock/tmp) failed: Not a directory: 1 Time(s) This is the command: doveadm backup -u user(a)domain.tld maildir:backupshare/daily/domain.tld/user Our main vmail directory is on an NFS share and seems to be working fine. This has only occurred recently. Can anyone offer any insights into what this is and fixing it if need be? -- Asai

Problems during replication
by Francis Augusto Medeiros-Logeay 02 May '20

02 May '20

Hi, I migrated my dovecot instance to a new server. I moved the mail directories, databases, etc. Replication is on, and I keep having these errors: May 02 16:19:45 dsync-local(francis(a)francisaugusto.com): Error: Couldn't lock /var/mail/vmail/francisaugusto.com/francis//.dovecot-sync.lock: fcntl(/var/mail/vmail/francisaugusto.com/francis//.dovecot-sync.lock, write-lock, F_SETLKW) locking failed: Timed out after 30 seconds (WRITE lock held by pid 178) May 02 16:19:45 doveadm: Error: Couldn't lock /var/mail/vmail/medeiros.co/inis//.dovecot-sync.lock: fcntl(/var/mail/vmail/medeiros.co/inis//.dovecot-sync.lock, write-lock, F_SETLKW) locking failed: Timed out after 30 seconds (WRITE lock held by pid 185) See the errors are both from dsync-local and doveadm. Any tips on how to fix this? Best, Francis

01 May '20

Hello, I would like to know if dovecot/pigeonhole provide a way to do sieve redirection with sender rewriting scheme (srs)? I apologize in advance if that e-mail address isn't meant for assistance, but I've asked on the official irc channel on freenode and was told to direct my query to dovecot(a)dovecot.org, I hope you won't mind. Thanking you in advance Best Regards Mathieu Gosset

Shared folder replication - query - can it be replicated?
by Daniel Botting 01 May '20

01 May '20

Hi, Further to my earlier posting to the mailing list this morning regarding replicating of public namespaces is it possible that a shared name space can be replicated: https://wiki.dovecot.org/SharedMailboxes/Shared We use LDAP, the thought being that an LDAP service account is created and the corresponding mailbox is shared to other mail users on the server. Kind regards Daniel

Public folder replication ( not replicating) - roadmap query
by Daniel Botting 01 May '20

01 May '20

Hi, We have a server pair running Dovecot 2.3.10 (latest stable) version directly from repo.dovecot.org and have mailbox and sieve replication working as required in production. I have setup a test pair with the exact same configuration and on each server setup public name space for a mailbox address such as jobs@ where multiple users would need to subscribe to this to view recruitment emails. This is not replicating as per the advice on the below url: - https://wiki.dovecot.org/Replication Is there an easily maintainable workaround at this time and is this on the roadmap for the developers, if so what time scale is being envisaged? Kind regards Daniel

Header search on Dovecot with SOLR
by Ricardo Machini Barbosa 28 Apr '20

28 Apr '20

Hello, I am using dovecot 2.3.0 with FTS Solr 7.7.2. I started having problems where the solr stopped working, I came to the conclusion that when a specific user is accessing his email, the queries made on SOLR are dropping this service. Apr 28 11:03:59 Error: imap(tullio(a)dominio.com.br)<125772><fdHRQlqkupe6zZkj>: fts_solr: Lookup failed: Request timed out (Request queued 180.186 secs ago, 2 times retried, 3 send attempts in 180.185 secs, 60.062 in last attempt, 60.063 in http ioloop, 0.000 in other ioloops, connected 60.062 secs ago) Analyzing the solr logs, we got an example query: http://127.0.0.1:8983/solr/dovecot/select?wt=xml&fl=uid,score&rows=15824&sor t=uid+asc&q=%7b!lucene+q.op%3dAND%7dhdr:%3ceyJlX21faWQiOjE1ODUxMiwidF9pZCI6O DUxMCwiZV9jX2lkIjoxLCJjX3BfdF9pZCI6MywiY19pZCI6MzQ4MzIzMDUsImVfaWQiOjg3NjYwL CJlX3RfaWQiOjYsInRzIjoiMjAyMC0wNC0yNCAxOTozMjoxMS4wIn0%3d(a)edrone.me%3e&fq=%2 Bbox:8ba9c7227a37835cbaf20100b047fe86+%2Buser:tullio@dominio.com.br What I could see is that this query in question was a search in the headers and not in the body. Should this query type go through FTS Solr? Reading the documentation I understand that the standard behavior is that header searches are made by dovecot and only bodies searches are made by Solr. I saw about a recent option called fts_enforced, where it is possible to forward header searches to FTS, but I am not using this option. I would like to know if my understanding is incorrect or if there is some kind of problem with dovecot? Regards, Ricardo

Dovecot LDAP/AD with exim as mta
by Benoît PELISSIER 28 Apr '20

28 Apr '20

Hi, I have done configuration dovecot/exim/samba4ad. I use dovecot-lda not exim to deliver mail. And dovecot to authentify users. I have users with mail address on AD. When i sent mail to user mail address, its working. I have distribution group or group with mail address on AD and users as member of this groups. But when i send mail to group mail address, its not working Dovecot-lda can do it ? Or i need do it with exim (or postfix) ? Thanks Benoît

Quota calculation with MySQL backend and replication.
by Reio Remma 27 Apr '20

27 Apr '20

Hello! Over the weekend I converted our Dovecot server from Maildir quota to MySQL backed quota and then provisioned a fresh replica server and seeded it via Dovecot replication. This morning most mailboxes were over quota, reporting twice the actual usage. I'm fairly certain it's the effect of having sql backed quota with both Dovecot servers using the same database. Can anyone tell me if this is a one-off problem stemming from replicating the 2nd server from scratch or should I be aware of other quirks concerning sql backed quota and replication? Thanks a bunch! Reio

Hierarchy separator recommendation?
by Admin Beckspaced 27 Apr '20

27 Apr '20

Dear dovecot list, I'm using Maildir as mailbox format. Is there any recommendation for the namespace hierarchy separator? Currently I didn't set any. So it is the default of dot '.' I'm switiching from a rather unknown IMAP Server called DBMail (http://www.dbmail.org/) Planning to synchronize the mailboxes via imapsync (https://github.com/imapsync/imapsync) Is there anything I should be thinking / planning about? Or can i always change this namespace hierarchy separator later on? Any hints or insights are more than welcome ;) thanks & greetings Becki
