(now from my subscribed account) Hi all.

Hi there! I've installed dovecot for debian from the dovecot-repo in the latest Version 2:2.3.4-2~stretch And i still get this error-messages. dovecot[5817]: imap(user.name)<26484><nzUgti58YaEuffpZ>: Error: Log synchronization error at seq=4,offset=5748 for /var/lib/dovecot/db/indexes/Maildir/user.name/Trash/dovecot.index: Append with UID 202, but next_uid = 203 I read in the release-notes, that doveadm force-resync can solve this problem... But it didn't I ran the command on all Mailboxes, but deleting a message in Thunderbird (= moving it into Trash) causes the error above. Do you need further informations? BG jakob

Mailing list address harvested for spamming
by dovecot-e51＠deemzed.uk 03 Dec '18

03 Dec '18

Not to stir the pot, but I notice my email address has recently been harvested from this list for spamming purposes. This email address is unique and not used for anything else. I'd distinguish this from spam sent to the mailing list itself, which is obviously different. Is there anything further that could be done to prevent this? -- Dave

Relocate subfolders to different mount point
by Marc Roos 03 Dec '18

03 Dec '18

I would like to relocate the subfolders of the Sent folder to a different location. Now send messages mail is stored in mbox format at the location /home/users/testuser/mail/.Sent. I would like to store the subfolders Sent/2017 and Sent/2018 at the location /home/archive/users/testuser/.Sent.2017 and /home/archive/users/testuser/.Sent.2018 Is this even possible? I am using currently using this mail_location: mail_location = mbox:~/mail:INBOX=/var/spool/mail/%u:CONTROL=~/mail/control:INDEX=/var/d ovecot/%u/index:LAYOUT=maildir++ /var/dovecot is on a ssd /var/spool/mail is on sda ~/mail is on sdb with these folders [@mail]# ls -ac1 .folderc .Drafts .foldera control .Trash.folderc .folderb .Sent .Sent.2018 .Trash

The tool metaphor is realistic. In my experience (which dates back to the 1980s), email ist a powerful tool, and people need to learn how to use it properly, with the appropriate software set. Especially in the area of technical mailing lists I see no reason to cater to dumb MUA software. > Email should be intitive If by "intuitive" you mean "used without engaging one's brain", I have to disagree.

Sieve broken after upgrade
by Pavel Stratil 02 Dec '18

02 Dec '18

Hi everyone, after switching to ubuntu (from debian) and running a newer dovecot --version 2.2.33.2 (d6601f4ec) i encountered a problem with configuring sieve. The mailserver has virtual maila accounts stored in /decrypted/%d/%n Prior, i used plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_before = /etc/dovecot/sieve/before.d } after the upgrade, I moved the sieve_before location on disk and changed this to plugin { sieve = file:~/sieve;active=~/.dovecot.sieve sieve_before = /var/lib/dovecot/sieve/before.d } only to see that sieve didnt forward e-mails anymore. Looking at the logs below, i suspect, that I didnt understood the meaning of sieve = file:~/sieve;active=~/.dovecot.sieve correctly: Dec 2 16:01:57 vao01 dovecot: lmtp(events(a)industra.space): Debug: Module loaded: /usr/lib/dovecot/modules/lib90_sieve_plugin.so Dec 2 16:01:57 vao01 dovecot: lmtp(events(a)industra.space): Debug: sieve: Pigeonhole version 0.4.21 (92477967) initializing Dec 2 16:01:57 vao01 dovecot: lmtp(events(a)industra.space): Debug: sieve: include: sieve_global is not set; it is currently not possible to include `:global' scripts.

I tried several combinations of configuring this, but I seem to miss some important point. Would you kindly help me get this right? Configs are attached. Thanks in advance, Pavel

Hi! It seems we accidentically had a high amount of subscribers temporarily disabled due to DMARC on some sender's host. We have now taken actions to prevent this in the future and all temporarily disabled members have been restored. Aki

Dovecot crash
by JCA 01 Dec '18

01 Dec '18

This happening when my Thunderbird client is trying to establish a connection with a Dovecot server. Some background first: 1) I am running Thunderbird 6.20.1 from a Linux client. 2) Other clients (e.g. Maildroid in my Android phone) do not have any issues. 3) The Dovecot software is version 2.2.9, running in a Linux server. 4) This may be the root of the problem: at some point, the Dovecot software was changed to version 2.3.1, and the reverted to 2.2.9. The crash started to appear when this reversion took place. My guess is that upgrading to 2.3.1 will eliminate this problem. However, in case that does not solve the problem, I would be grateful if anybody could throw some light into exactly what is going on here, and whether it can be fixed even without the need of upgrading to 2.3.1. What follows are the traces generated by Dovecot 2.2.9 when a connection is attempted from Thunderbird, with usernames and IP addresses disguised for privacy, and some blank lines inserted for readability: Nov 28 13:36:20 imap-login: Info: Login: user=<xyz>, method=PLAIN, rip=xxx.yyy.z zz.154, lip=aaa.bbb.ccc.7, mpid=29245, TLS, session=<q7jNhL97qQDMhbWa> Nov 28 13:36:20 imap(xyz): Panic: file mail-index-sync-keywords.c: line 227 (key words_update_records): assertion failed: (data_offset >= sizeof(struct mail_index_record)) Nov 28 13:36:20 imap(xyz): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so. 0(+0x65626) [0xb75ae626] -> /usr/lib/dovecot/libdovecot.so.0(+0x6569f) [0xb75ae6 9f] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0xb756180e] -> /usr/lib/dove cot/libdovecot-storage.so.0(mail_index_sync_keywords+0x707) [0xb76cb6b7] -> /usr /lib/dovecot/libdovecot-storage.so.0(mail_index_sync_record+0xf7) [0xb76cc167] - > /usr/lib/dovecot/libdovecot-storage.so.0(mail_index_sync_map+0x2a4) [0xb76cd22 4] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_index_map+0x57c) [0xb76bcb9c ] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0xb7c2a) [0xb76b7c2a] -> /usr/lib /dovecot/libdovecot-storage.so.0(+0xb7daa) [0xb76b7daa] -> /usr/lib/dovecot/libd ovecot-storage.so.0(mail_index_open+0x114) [0xb76b7f54] -> /usr/lib/dovecot/libd ovecot-storage.so.0(index_storage_mailbox_open+0xab) [0xb76a808b] -> /usr/lib/do vecot/libdovecot-storage.so.0(+0x5a481) [0xb765a481] -> /usr/lib/dovecot/libdove cot-storage.so.0(+0x5a6f2) [0xb765a6f2] -> /usr/lib/dovecot/libdovecot-storage.s o.0(+0x7a017) [0xb767a017] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_o pen+0x26) [0xb767a1d6] -> dovecot/imap(client_open_save_dest_box+0x79) [0x805dca 9] -> dovecot/imap() [0x8052678] -> dovecot/imap(command_exec+0x32) [0x805d7a2] -> dovecot/imap() [0x805c746] -> dovecot/imap() [0x805c820] -> dovecot/imap(clie nt_handle_input+0x125) [0x805cad5] -> dovecot/imap(client_input+0x71) [0x805ce91 ] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x42) [0xb75c1292] -> /usr /lib/dovecot/libdovecot.so.0(io_loop_handler_run+0xdb) [0xb75c22cb] -> /usr/lib/ dovecot/libdovecot.so.0(io_loop_run+0x48) [0xb75c0cd8] -> /usr/lib/dovecot/libdo vecot.so.0(master_service_run+0x2d) [0xb756728d] -> dovecot/imap(main+0x2bf) [0x 8066fef] -> /lib/libc.so.6(__libc_start_main+0xe6) [0xb73cfdb6] Nov 28 13:36:20 imap(xyz): Fatal: master: service(imap): child 29245 killed with signal 6 (core dumps disabled) Nov 28 13:36:20 imap-login: Info: Login: user=<xyz>, method=PLAIN, rip=xxx.yyy.z zz.154, lip=aaa.bbb.ccc.7, mpid=29247, TLS, session=<xPzShL97lADMhbWa> Nov 28 13:36:21 imap(xyz): Panic: file mail-index-sync-keywords.c: line 227 (key words_update_records): assertion failed: (data_offset >= sizeof(struct mail_inde x_record)) Nov 28 13:36:21 imap(xyz): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so. 0(+0x65626) [0xb7757626] -> /usr/lib/dovecot/libdovecot.so.0(+0x6569f) [0xb77576 9f] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0xb770a80e] -> /usr/lib/dove cot/libdovecot-storage.so.0(mail_index_sync_keywords+0x707) [0xb78746b7] -> /usr /lib/dovecot/libdovecot-storage.so.0(mail_index_sync_record+0xf7) [0xb7875167] - > /usr/lib/dovecot/libdovecot-storage.so.0(mail_index_sync_map+0x2a4) [0xb787622 4] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_index_map+0x57c) [0xb7865b9c ] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0xb7c2a) [0xb7860c2a] -> /usr/lib /dovecot/libdovecot-storage.so.0(+0xb7daa) [0xb7860daa] -> /usr/lib/dovecot/libd ovecot-storage.so.0(mail_index_open+0x114) [0xb7860f54] -> /usr/lib/dovecot/libd ovecot-storage.so.0(index_storage_mailbox_open+0xab) [0xb785108b] -> /usr/lib/do vecot/libdovecot-storage.so.0(+0x5a481) [0xb7803481] -> /usr/lib/dovecot/libdove cot-storage.so.0(+0x5a6f2) [0xb78036f2] -> /usr/lib/dovecot/libdovecot-storage.s o.0(+0x7a017) [0xb7823017] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_o pen+0x26) [0xb78231d6] -> dovecot/imap(client_open_save_dest_box+0x79) [0x805dca 9] -> dovecot/imap() [0x8052678] -> dovecot/imap(command_exec+0x32) [0x805d7a2] -> dovecot/imap() [0x805c746] -> dovecot/imap() [0x805c820] -> dovecot/imap(clie nt_handle_input+0x125) [0x805cad5] -> dovecot/imap(client_input+0x71) [0x805ce91 ] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x42) [0xb776a292] -> /usr /lib/dovecot/libdovecot.so.0(io_loop_handler_run+0xdb) [0xb776b2cb] -> /usr/lib/ dovecot/libdovecot.so.0(io_loop_run+0x48) [0xb7769cd8] -> /usr/lib/dovecot/libdo vecot.so.0(master_service_run+0x2d) [0xb771028d] -> dovecot/imap(main+0x2bf) [0x 8066fef] -> /lib/libc.so.6(__libc_start_main+0xe6) [0xb7578db6] Nov 28 13:36:21 imap(xyz): Fatal: master: service(imap): child 29247 killed with signal 6 (core dumps disabled)

Replacing email envelope
by jon.sp2＠wp.pl 30 Nov '18

30 Nov '18

Hi, Could you please advice how I can replace envelope of a message received on my server? Best would be using sieve. Simple case - email A(a)example.com receives message, which I'd like to repack into new envelope (I want to have control what values in the envelope will be there - from, to, replay-to et.c) and send to B(a)test.com . At first I wanted to use editheader extension, but it is not allowing me to modify From or To values as far as I can tell. Another idea was to use envelope, but I don't see any way of editing values. Only reading. Now, I am thinking of writing script and from sieve it will be passed there, where I'll do message parsing and send new message using mutt or something similar. Frankly speaking I suppose there is much better solution to that and I'd appreciate any advice on the topic. Thanks, Jon

rspamd / imapsieve script is not executed/called
by Michael Ludwig 30 Nov '18

30 Nov '18

Hi to all of you, as I am struggling around with this a week or so I'm afraid I have to ask for help here. The problem is sitting right in front of the computer, as most of the time. ;-) So let me explain: Dovecot is working properly for IMAP with LE certificates, so I thought it's time to continue with Christoph Haas tutorial primarily and other blogs and tutorials for setting up the server. Next part would be to get rspamd learning what mails the user puts into junk folder. I followed the tutorial, but it will not work. Also I tried to get into debug mode, but I feel that dovecot is not really logging too much. Server is freshly set up Ubuntu 18.04.1, latest patchlevel with packages mostly from Ubuntu sources, except rspamd, but this was added as ppa if my remembering is correct. This is what I get on syslog, whilst *.* is being put at /var/log/allmessages. ######################################### Nov 25 23:30:50 myserver dovecot: imap(info(a)mydomain.tld): Debug: INBOX/Junk: Mailbox opened because: UID move Nov 25 23:30:50 myserver dovecot: imap(info(a)mydomain.tld): Debug: imapsieve: mailbox INBOX/Junk: MOVE event Nov 25 23:30:50 myserver dovecot: imap(info(a)mydomain.tld): Debug: sieve: Pigeonhole version 0.4.21 (92477967) initializing Nov 25 23:30:50 myserver dovecot: imap(info(a)mydomain.tld): Debug: sieve: Sieve imapsieve plugin for Pigeonhole version 0.4.21 (92477967) loaded Nov 25 23:30:50 myserver dovecot: imap(info(a)mydomain.tld): Debug: sieve: Sieve Extprograms plugin for Pigeonhole version 0.4.21 (92477967) loaded Nov 25 23:30:50 myserver dovecot: imap(info(a)mydomain.tld): Debug: imapsieve: Static mailbox rule [1]: mailbox=`Junk' from=`*' causes=(COPY) => before=`file:/etc/dovecot/sieve/report-spam.sieve' after=(none) Nov 25 23:30:50 myserver dovecot: imap(info(a)mydomain.tld): Debug: imapsieve: Static mailbox rule [2]: mailbox=`*' from=`Junk' causes=(COPY) => before=`file:/etc/dovecot/sieve/report-ham.sieve' after=(none) ######################################### So as far as I can interpret there is absolutely no script called when I move a mail from inbox to junk folder in Thunderbird.

Best way of merging mbox files
by Marc Roos 30 Nov '18

30 Nov '18

When concatenating mbox files like described here https://xaizek.github.io/2013-03-30/merge-mbox-mailboxes/. You will end up with an 'unsorted' mbox file. Is this going to be a problem esspecially when they are large >2GB's and new emails will be written to it? The email client nicely sorts the message from folder A "foldera 5 last" as last, but of course the mbox is not like this. Is there a better solution for merging files? Having: A folder A with messages: From Subject Received Size test foldera 1 16:18 665 B test foldera 2 16:18 665 B test foldera 3 16:18 665 B test foldera 4 16:18 665 B test foldera 5 last 16:29 670 B A folder B with messages: From Subject Received Size test folderb 1 16:23 665 B test folderb 2 16:24 665 B test folderb 3 16:24 665 B test folderb 4 16:24 665 B test folderb 5 16:24 665 B [@ mail] cat .foldera .folderb > .folderc Getting a folder C with messages: From Subject Received Size test foldera 1 16:18 665 B test foldera 2 16:18 665 B test foldera 3 16:18 665 B test foldera 4 16:18 665 B Mail System Internal Data DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA 16:19 454 B test folderb 1 16:23 665 B test folderb 2 16:24 665 B test folderb 3 16:24 665 B test folderb 4 16:24 665 B test folderb 5 16:24 665 B test foldera 5 last 16:29 670 B

"merging" folders Sent-Items Sent-Messages Sent
by Marc Roos 29 Nov '18

29 Nov '18

I have a running server and would like to clean up a bit, and merge sent folders and trash folders etc. Is this best done via the mailbox alias plugin like mentioned here? Or is there a better way? I prefer to have one folder listed at the client, and not "Unfortunately it also means that some clients will download the same mails to local cache multiple times." https://wiki2.dovecot.org/Plugins/MailboxAlias dovecot-2.2.10-8.el7.x86_64 CentOS Linux release 7.5.1804 (Core)

Installing on Mojave, with Homebrew and mysql

25 Nov '18

I’m using Homebrew to install Dovecot on Mojave, but have to modify the formula to add ‘--with-mysql’. Unfortunately compiling always fails with: checking for mysql_config... NO checking for mysql_init in -lmysqlclient... no configure: error: Can't build with MySQL support: libmysqlclient not found I added: ENV['LD']="-L/usr/local/opt/mysql(a)5.7/lib" to the ‘def install’ section of the formula, but it still fails. config.log shows: … KRB5_LIBS='' LD='-L/usr/local/opt/mysql(a)5.7/lib/' LDAP_LIBS=‘' … And mysqlclient is here: $ locate mysqlclient /usr/local/Cellar/mysql(a)5.7/5.7.24/lib/libmysqlclient.20.dylib /usr/local/Cellar/mysql(a)5.7/5.7.24/lib/libmysqlclient.a /usr/local/Cellar/mysql(a)5.7/5.7.24/lib/libmysqlclient.dylib /usr/local/Cellar/mysql(a)5.7/5.7.24/lib/pkgconfig/mysqlclient.pc I changed the formula to: ENV['LD']="-L/usr/local/Cellar/mysql(a)5.7/5.7.xn--24/lib/-236c And still get the same thing. Any suggestions? Thanks, James.

Testing validity of Dovecot config in a script
by Ralph Seichter 24 Nov '18

24 Nov '18

While trying to determine a given configuration is valid from within a script, I found that the following works with Dovecot version 2.3.2.1: #!/usr/bin/env bash doveconf -n >/dev/null || echo "Config is invalid" However, the return code is not documented in the doveconf manual page, and I wonder if the observed behaviour can be relied on? Is this the recommended method to test configuration validity? Personally, I'd like to have a dedicated call available. Something like # Proposal: "-t" for "test config" doveconf -t [-c config-file] with documented return codes would be ideal. -Ralph

Problems after upgrading to 2.3.2.1
by Joel Dahl 23 Nov '18

23 Nov '18

Hi, I've just upgraded dovecot from 2.2.35 to 2.3.2.1 on my mail server and noticed something odd. My mail clients (mutt and Apple mail) both stopped seeing new mail in my mailboxes. For example, ~/Maildir/mailinglist1/new has 5 new mails. In mutt, vieweing the list of mailboxes mutt reports 0 new mail for "mailinglist1". Opening up the actual mailbox in mutt reveals the 5 new mails. Going back to the list of mailboxes, mutt now correctly reports 5 unread mails. Waiting a few hours, and about 10 new mails have arrived, but mutt still says 5 unread. This is the same for every mailbox. As a test I deleted the index files for a specific mailbox and restarted dovecot. But it didn't help. I use procmail to deliver my mail into the Maildir folders, if that matters. Any ideas? I haven't changed my dovecot configuration in a long time, except for adding ssl_dh after the upgrade. My config is below: auth_mechanisms = plain login imap_client_workarounds = delay-newmail tb-extra-mailbox-sep tb-lsub-flags info_log_path = /var/log/dovecot-info.log log_path = /var/log/dovecot.log mail_location = maildir:~/Maildir mail_privileged_group = mail maildir_very_dirty_syncs = yes passdb { args = session=yes dovecot driver = pam } protocols = imap service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } ssl = required ssl_cert = </path/to/cert.pem ssl_dh = # hidden ssl_key = # hidden userdb { driver = passwd } -- Joel

doveadm dsync-server doesn't use user parameter?
by Harald Leithner 23 Nov '18

23 Nov '18

Hi, I tried to migrate my dovecot 2.2 to a new server with a other storage configuration and dovecot 2.3. New (and old) Server uses mysql for user information I use the following storage settings mail_home = /storage1/vmail/%{userdb:path} mail_location = mdbox:/storage1/fast/%{userdb:path}:FULLDIRNAME=iTrNiCs-DBOx-mAiLs:INDEX=/storage1/indexes/vmail/%{userdb:path}:ALT=/storage1/slow/%{userdb:path}:VOLATILEDIR=/tmp/%{userdb:path} userdb:path is generated by the mysql query and ends in something like "2000/6" SQL: CONCAT(u.idAccount, '/', u.idUser) AS userdb_path If I login with imap dovecot is creating the INBOX on the correct path /storage1/fast/2000/6/mailboxes/INBOX btw. it creates a link to dbox-alt-root but without creating the target directory is this expected? Now if I start doveadm backup -u <username> remote:mailstore2 it ignores it seams that dsync-server doesn't make a database query and doesn't use the userdb_path field. It only uses /storage1/fast/mailboxes/INBOX as path. Is this a problem with my configuration? thx --- doveconf -n # 2.3.3 (dcead646b): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.3 (f018bbab) # OS: Linux 4.15.18-7-pve x86_64 Debian 9.6 zfs # Hostname: mailstore2 auth_cache_negative_ttl = 1 secs auth_cache_size = 10 M auth_cache_ttl = 1 secs auth_master_user_separator = * auth_mechanisms = PLAIN LOGIN APOP auth_verbose = yes default_client_limit = 600 default_vsz_limit = 512 M dict { lastlogin = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext sqlacl = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext sqlquota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } disable_plaintext_auth = no first_valid_gid = 1001 first_valid_uid = 1001 hostname = mailstore2 imap_hibernate_timeout = 1 mins imap_id_log = * imap_id_send = * imap_idle_notify_interval = 10 mins imap_logout_format = bytes=%i/%o instance_name = mailstore2 last_valid_gid = 1001 last_valid_uid = 1001 lda_original_recipient_header = X-LDA-Original-To lmtp_rcpt_check_quota = yes login_greeting = ITronic Mail Store login_trusted_networks = 172.22.14.0/24 mail_cache_min_mail_count = 5 mail_gid = vmail mail_home = /storage1/vmail/%{userdb:path} mail_location = mdbox:/storage1/fast/%{userdb:path}:FULLDIRNAME=iTrNiCs-DBOx-mAiLs:INDEX=/storage1/indexes/vmail/%{userdb:path}:ALT=/storage1/slow/%{userdb:path}:VOLATILEDIR=/tmp/%{userdb:path} mail_plugins = lazy_expunge acl quota mail_log notify mail_prefetch_count = 100 mail_server_admin = mailto:postmaster@example.com mail_server_comment = Mail System mail_shared_explicit_inbox = yes mail_uid = vmail managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate mime foreverypart extracttext vacation-seconds mdbox_preallocate_space = yes namespace { hidden = yes list = no location = mdbox:/storage1/fast/%{userdb:path}:MAILBOXDIR=expunged:LISTINDEX=expunged.list.index:FULLDIRNAME=iTrNiCs-DBOx-mAiLs:INDEX=/storage1/indexes/vmail/%{userdb:path}:ALT=/storage1/slow/%{userdb:path}:VOLATILEDIR=/tmp/%{userdb:path} prefix = "#EXPUNGED/" subscriptions = no type = private } namespace { list = children location = mdbox:%%h/mdbox prefix = "#Users/%%u/" separator = / subscriptions = yes type = shared } namespace inbox { hidden = no inbox = yes location = mailbox Archvie { special_use = \Archive } mailbox Drafts { special_use = \Drafts } mailbox Sent { special_use = \Sent } mailbox Spam { special_use = \Junk } mailbox Trash { special_use = \Trash } prefix = separator = / subscriptions = yes type = private } passdb { args = /etc/dovecot/master-users driver = passwd-file master = yes result_success = continue-ok } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { acl = vfile acl_shared_dict = proxy::sqlacl last_login_dict = proxy::lastlogin last_login_key = #

Re: LDAP stored quota
by Aki Tuomi 23 Nov '18

23 Nov '18

I noticed that you sent replies to me directly... Anyways, seems the problem was that the LDAP user_attrs is missing commas, and the mailRoutingAddress is used wrong, so the correct syntax would be: user_attrs = \ mailRoutingAddress=user, \ =uid=vmail, \ =gid=mail, \ =home=/var/mail/%d/%n, \ =quota_rule=*:bytes=%{ldap:departmentNumber} Aki > On 22 November 2018 at 15:29 Vincent Seynhaeve <vlamsdoem(a)gmail.com> wrote: > > > doveadm quota recalc -u test doesn't give anything. > Bellow the ouput of the `doveconf -n` and `doveadm user test` > > doveconf -n > # 2.2.10: /etc/dovecot/dovecot.conf > # OS: Linux 3.10.0-862.11.6.el7.x86_64 x86_64 CentOS Linux release 7.5.1804 > (Core) xfs > auth_debug = yes > auth_mechanisms = plain login > auth_verbose = yes > mail_debug = yes > mail_gid = mail > mail_home = /var/mail/%d/%n > mail_location = maildir:/var/mail/%d/%n/Maildir > mail_plugins = " quota" > mail_uid = vmail > managesieve_notify_capability = mailto > managesieve_sieve_capability = fileinto reject envelope encoded-character > vacation subaddress comparator-i;ascii-numeric relational regex imap4flags > copy include variables body enotify environment mailbox date ihave > mbox_write_locks = fcntl > namespace inbox { > inbox = yes > location = > mailbox Drafts { > special_use = \Drafts > } > mailbox Junk { > special_use = \Junk > } > mailbox Sent { > special_use = \Sent > } > mailbox "Sent Messages" { > special_use = \Sent > } > mailbox Trash { > special_use = \Trash > } > prefix = > } > passdb { > args = /etc/dovecot/dovecot-ldap.conf.ext > driver = ldap > } > plugin { > quota = maildir:User quota > quota_grace = 10%% > quota_rule2 = Trash:storage=+100M > quota_status_nouser = DUNNO > quota_status_overquota = 552 5.2.2 Mailbox is full > quota_status_success = DUNNO > sieve = ~/.dovecot.sieve > sieve_dir = ~/sieve > } > protocols = imap pop3 lmtp sieve > service auth { > unix_listener /var/spool/postfix/private/auth { > group = postfix > mode = 0666 > user = postfix > } > unix_listener auth-userdb { > group = mail > mode = 0600 > user = vmail > } > } > service imap-login { > inet_listener imap { > port = 0 > } > } > service managesieve-login { > inet_listener sieve { > port = 4190 > } > } > service pop3-login { > inet_listener pop3 { > port = 0 > } > inet_listener pop3s { > port = 0 > } > } > ssl = required > ssl_cert = </etc/pki/tls/certs/imap.example.com.crt > ssl_key = </etc/pki/tls/private/imap.example.com.key > userdb { > args = /etc/dovecot/dovecot-ldap.conf.ext > driver = ldap > } > protocol lda { > mail_plugins = " quota sieve" > } > protocol imap { > mail_plugins = " quota imap_quota" > } > > > > > doveadm user test > field value > uid vmail > gid mail > home /var/mail//test > mail maildir:/var/mail//test/Maildir > mailRoutingAddress user =uid=vmail =gid=mail =home=/var/mail//test > =quota_rule=*:bytes=1M > > > Le jeu. 22 nov. 2018 à 14:18, Aki Tuomi <aki.tuomi(a)open-xchange.com> a > écrit : > > > Can you provide output of `doveconf -n` and `doveadm user test`?

Same emails appearing multiple time after upgrade to version 2.33

22 Nov '18

Hi, I have update today dovecot and dovecot pigeonhole to the latest version available on my centos 7. It’s a small email servers with postfix/amavisd/clamav/spamasssin. I had dovecot for IMAP/POP3 with spam plugins to store spam message automatically into the spam folder. After the upgrade, I was noticed by some of my users that they have in their message the same message appearing 2,3 even 10 times. I had the same behavior when using roundecube I was able to stop this after removing pigeonhole rpm (removing/disabling the config was not enough). Would appreciate your help to understand what is wrong with my config.

Multi-server but small scale
by Daniel Miller 21 Nov '18

21 Nov '18

I have a small but critical server that supports our group. As a single server - it's obviously a single-point-of-failure for lots of things. As I just experienced...again. It was a lot more fun building systems from components when I was younger... Previously 3rd-party hosted solutions didn't look attractive for several reasons...but I'm seeing prices now for cloud virtual machines that are stupid cheap. Even if they wind up being limited speed & availability - it would seem they'd be a lot better than nothing! So I'm considering having at least one backup server for various services - obviously that includes mail. So now I have to wonder about the backend. And while I think I'm reasonably current with networked file systems (not distributed or cluster) I haven't played with replication for a quite a while. For this particular usage (I'm envisioning two servers total) - is there a need/reason to use any form of networked/distributed/cluster file storage? Or would this be accomplished via "pure" Dovecot - dsync replication would keep things updated between the servers and director would handle the connections? So with identically configured SMTP servers, passing to the local LMTP agents, the file system would be "purely local" with no NFS or other interconnection? -- Daniel

analysing of dmarc report
by Poliman - Serwis 21 Nov '18

21 Nov '18

I have a problem with understanding dmarc reports and some features. I attach two reports. First one come from google.com, second one from tumieszkamy.pl. On my server is dns zone of domain kamir-transport.pl but whole mail service is deployed on Google - in dns zone MX points to Google and there are all mailboxes, aliases etc. Last time I have configured dkim and dmarc policies and I got two reports. Honestly I don't know why two, from two different providers - google.com and tumieszkamy.pl. Moreover in report originating from google I see IP of my server [which fails spf and dkim policies] and I don't understand why this IP is evaluated? Second thing which I don't understand is second report which I got from tumieszkamy.pl. SPF record in dns zone of domain kamir-transport.pl was looking like below (now I changed it to slightly different): *v=spf1 mx include:_spf.google.com <http://spf.google.com> -all* Does anybody could help uderstand these things? -- *Pozdrawiam / Best Regards* *Piotr Bracha*

Quota in MySql Dict not recalculate automatic
by SUnsin＠gv-bayern.de 20 Nov '18

20 Nov '18

Hi, I have a working Installation with: Ubuntu 16.04 LTS Dovecot 2.2.22 MySql 5.7.24 Postfixadmin 3.2 Apache 2.4.18 Rainloop 1.12.1 I manage the E-Mail Accounts with postfixadmin in a MySql-DB. Also I use quotas with Quota Backend postfixadmin-DB (dict). Everything works fine. Now I installed a new Server with the following Versions and migrate the Configs to the new System. Ubuntu 18.04 LTS Doveot 2.2.33 MySQL 5.7.24 Postfixadmin 3.2 Apache 2.4.18 Rainloop 1.12.1 The Problem is now: When I receive a E-Mail, the quota will not Update (recalculate) automatical in the MySql-DB from Dovecot. In the old System there execute the SQL Statement after receiving a E-Mail, for example: UPDATE quota2 SET bytes=bytes+3076,messages=messages+1 WHERE username = <E-Mail Address> On the new System with the newer Dovecot Version, the Statement never comes after receive an E-Mail. With Dovecot Version 2.3 on the old System with Ubuntu 16.04, everything works fine with the same config. Is a BUG in the Dovecot Version 2.2.33 possible? Can everbody help me?

Update virtual folders via doveadm?
by Daniel Miller 20 Nov '18

20 Nov '18

I'm trying to have my server maintain it's FTS indexes reasonably current at all times. From prior threads, and based on my namespace configuration, I have the following hourly cronjob: doveadm index -A -q '*' doveadm index -A -q 'shared/*' doveadm index -A -q 'virtual/*' This seems to work just fine to maintain the FTS (Solr). However - as I understand it Dovecot's virtual folders are not updated with new mails until they are accessed by a client. Therefore the above command sequence would work fine for my default namespace and the shared - but the virtual namespace won't actually be current. So... Would a command such as: doveadm mailbox status -A messages virtual/* Be appropriate to run prior to the virtual/* FTS indexing? -- Daniel

IMAP Limitations with Outlook 2013?
by Robert Adkins 19 Nov '18

19 Nov '18

Good Day! I have a fairly new user on my network that has, over about 10 months, created in root inbox and nested sub-folders totaling over 900 individual folders. In the past few weeks, newly created folders will be visible in Outlook 2013, but when an email is moved into that folder, it is no longer visible. I can ssh into the server, drill down to that sub-folder and see the email in the folder AND it is also available to be seen without issue in Thunderbird. I know this is a longshot, but if there is some feature that I haven't found in Dovecot to force Outlook to synchronize with all the folders/sub-folders, please let me know. Beyond that. With this particular users habits, over the next 5 years, there could be nearly 10,000 folders/sub-folders. Does anyone know if this will create any problems with Dovecot or is this JUST a Microsoft software problem? -- Best Regards, Robert Adkins IT Manager/Tool Designer Impel Industries, Inc. 586-254-5800

macOS Mojave: setgroups(501) failed: Too many extra groups
by Heiko W. Rupp 18 Nov '18

18 Nov '18

Hello, I have recently upgraded to macOS 10.14 (Mojave) and am running into an issue where one use can no longer log into dovecot via imap. Log shows Oct 11 08:10:27 imap(hwr)<12659><YpC/0+133+EAAAAAAAAAAAAAAAAAAAAB>: Fatal: setgroups(501) failed: Too many extra groups and indeed, the user is in 17 groups, which is more than NGROUPS_MAX (16). Another user with << 16 groups can log in fine. Unfortunately it is not (easily) doable to reduce the number of groups, as macOS seems to set them internally. Is there a config option that I am missing to work around this? Looking at the source, I see this is handled in src/lib/restrict-access.c::fix_groups_list(), where above the call to setgroups() a gid_list2 is constructed. I wonder if one could have a config option to prevent adding all those extra groups, which then make the call to setgroups() fail Any help appreciated Heiko -- hwr(a)pilhuhn.de m:0179/207 4919 b:http://pilhuhn.blogspot.com

Re: Issue sharing folders with Thunderbird
by Jason Perry 17 Nov '18

Hi Aki I see what you are saying, and no I don’t believe so. I’m using typical /etc/passwd for the user db. I reviewed https://wiki.dovecot.org/UserDatabase/ExtraFields <https://wiki.dovecot.org/UserDatabase/ExtraFields> but I’m not clear on how to actually return system_user userdb attribute. I also have set mail_user_groups = sharedusers in dovecot.conf and then in /etc/group put all the users with mailboxes into the sharedusers group. I can see why that wouldn’t work if the above is not set. Can you point me in the right direction on how to pass that information?

For example, lets say user u2.name creates a folder called “starbucks” and uses the IMAP commands to share it out to user operations.

Mail slowed down to a crawl...
by StarionTech (IMAP) 16 Nov '18

16 Nov '18

Been moving along just fine for a couple years now, then in the last two days, email has slowed to a crawl. Retrieving email via IMAP is very slow, progress bar in the mail client shows that it is downloading messages almost constantly, like it never closes the connection, or it’s getting the messages very slowly. The server that dovecot/postfix is on has also bogged down to a crawl. The postfix queue is sitting with hundreds of queued up good customer email. It’s almost acting like dovecot is not getting the messages from postfix, or they’re being delayed for some reason. How to approach fixing this? Jeff J.

dovecot 2.2/openssl 1.0 vs dovecot 2.3/openssl 1.1.1 ssl regression
by Arkadiusz Miśkiewicz 15 Nov '18

Hi. I'm considering dovecot migration from 2.2.36 run with openssl 1.0.2o to dovecot 2.3.3 run with openssl 1.1.1. Currently I have both variants running with identical configs and certs (the only differences are due to config syntax changes in dovecot 2.3), so for example on both I have: ssl_ca = </etc/openssl/certs/wildcard_ca.pem (this file contains single intermediate certificate of my CA) ssl_cert = </etc/openssl/certs/wildcard_crt.pem (this contains single cerificate for my *.example.com domain) ssl_key = # hidden, use -P to show it (and one key) No alt certs in use. Chain is: - CA trusted by clients (this certificate isn't provided by my dovecot, it's not needed) - wildcard_ca.pem - intermediate CA - wildcard_crt.pem - wildcard certificate for my *.example.com domain dovecot 2.2.36 behaviour is to provide wildcard_ca.pem and wildcard_crt.pem to the client - that behaviour is OK. Client has full trust chain. dovecot 2.3.3 provides only wildcard_crt.pem certificate to the client which is a big problem because missing wildcard_ca.pem (intermediate certificate) breaks chain and client is not able to verify trust chain. Testing is done with simple: openssl s_client -connect my.example.com:143 -starttls imap -servername my.example.com -showcerts 2.3.x announcements and upgrade wiki mention no such behaviour change, so I assume it is a regression. Now doing cat wildcard_ca.pem >> wildcard_crt.pem solves the problem and dovecot starts providing both certs to clients but if that's the proper way of solving this issue then what's the point of having ssl_ca config setting? Ideas? -- Arkadiusz Miśkiewicz, arekm / ( maven.pl | pld-linux.org )

FETCH BODY vs FETCH BODYSTRUCTURE + FETCH BODY.PEEK
by Alessio Cecchi 15 Nov '18

15 Nov '18

Hello, we are developing a web page, for a ticket system, to show the email messages ordered by the biggest attachments size present in an IMAP folder, with a pagination of 100 messages per page. Each raw represents a message with "DATE, FROM, SUBJECT, the preview (the first 500 chars of the text/html of the messsage) and the list of the attachments (name + size) it contains. The problem is that the page load is VERY slow because we fetch the entire BODY of all 100 messages, in order to get the preview and the attachments name and size. Now, considering that each messages can contain up to 50 MB of attachments, we risk to download 5000MB from IMAP for every page. An option might be to perform two FETCH for each message: - one fetch with just the BODYSTRUCTURE (where we can get the attachments name and size and the text/html parts). - one fetch with the body parts (BODY.PEEK[]) we need to build the preview (text + html). We are wondering if there is a single FETCH command to get the text and html parts (needed to build the preview) with only the name and the size of the attachments without downloading the entire message. Thanks. -- Alessio Cecchi Postmaster @ http://www.qboxmail.it https://www.linkedin.com/in/alessice
