Solr: URI Too Long
by azurit＠pobox.sk 29 Nov '18

29 Nov '18

Hi, i'm quite often getting this error: Error: fts_solr: Lookup failed: 414 URI Too Long Most web servers are limiting URI length to 8192 characters. Why not to use POST instead of GET when communicating with Solr? Solr is able to handle this ok, also see: https://dzone.com/articles/solr-select-query-get-vs-post azur

determine why mail clients download mails 2nd time
by Poliman - Serwis 29 Nov '18

29 Nov '18

I have strange problem. In last Friday I had a problem with dovecot. It didn't see directories with mailboxes in /var/vmail. Somehow it crashed because probably two things (a lot of this type of lines in mail.err file): *Nov 23 07:05:02 s1 dovecot: lda(poli(a)poli.li <poli(a)poli.li>): Error: User initialization failed: Initializing mail storage from mail_location setting failed: mkdir(/var/vmail/poli.li/poli/Maildir <http://poli.li/poli/Maildir>) failed: Permission denied (euid=5000(vmail) egid=5000(vmail) missing +w perm: /var/vmail, dir owned by 0:0 mode=0755)* and maybe *Nov 12 09:27:59 s1 dovecot: imap(artur(a)firmastanaszek.pl <artur(a)firmastanaszek.pl>): Error: Corrupted index cache file /var/vmail/firmastanaszek.pl/artur/Maildir/dovecot.index.cache <http://firmastanaszek.pl/artur/Maildir/dovecot.index.cache>: Broken MIME parts for mail UID 559 in mailbox INBOX: Cached MIME parts don't match message during parsing: Cached header size mismatch (parts=)Nov 12 09:27:59 s1 dovecot: imap(artur(a)firmastanaszek.pl <artur(a)firmastanaszek.pl>): Error: unlink(/var/vmail/firmastanaszek.pl/artur/Maildir/dovecot.index.cache <http://firmastanaszek.pl/artur/Maildir/dovecot.index.cache>) failed: No such file or directory (in mail-cache.c:28)* and after this event probably all mailboxes download again all emails from 1.11 to 22.11. They were duplicated in mail clients. -- *Pozdrawiam / Best Regards* *Piotr Bracha*

Dovecot Version: 2.3.2.1 Hello Mailing List, We are having a random issue in a couple of our production servers, where one of the child processes randomly dies with an out of memory error (see below): Nov 26 11:58:17 config: Fatal: pool_system_malloc(8192): Out of memory Nov 26 11:58:17 pop3-login: Fatal: Error reading configuration: read(/var/run/dovecot/config) failed: EOF Nov 26 11:58:17 config: Fatal: master: service(config): child 29696 returned error 83 (Out of memory (service config { vsz_limit=2048 MB }, you may need to increase it) - set CORE_OUTOFMEM=1 environment to get core dump) We only use dovecot for internal application POP3 mail access from a mailbox, and there is under 10 connecting applications.

LDAP login fails after LDAP server restart

25 Nov '18

Hi! Just udated my Fedora dovecot to version 2.2.36 and found that after the update dovecot will fail all LDAP logins after slapd has been restarted during the logrotate. Restarting dovecot fixes the problem. Is there a bug preventing dovecot to reopen the LDAP session when it fails? Best Dag

Installing on Mojave, with Homebrew and mysql
by James Brown 25 Nov '18

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.

Is there any information on using dovecot on Mojave? I have been using Mac OS Server for a few years and looking for the preferred way to move to Mojave since dovecot and postfix admin support has been dropped by Apple.

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`?

Core dump during UID Search

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
