Search problems after activating fts/solr

Hi, after activating fts/solr, we can see a changed behavior of standard (not fulltext) searches. For example, when searching the 'From' field for something(a)example.com, before activating solr it was ok to start search for word 'some' and the result was correct and complete (all messages from that user was found). After activating fts/solr, searches like this are returning none or only part of messages - i need to search for 'something' to get correct and complete result. Any hints? azur

Fwd: Some mails do not get replicated anymore after memory-exhaust
by Christoph Kluge 02 Mar '17

02 Mar '17

Hey guys, overall I have an working dovecot replication between 2 servers running on amazon cloud. Sadly I had some messages that my server ran out of memory. After investigating a little bit further I realized that some mails didn't got replicated, but I'm not sure if this was related to the memory exhaust. I was expecting that the full-sync would catch them up but sadly it's not. Attached I'm adding: * /etc/dovecot/dovecot.conf from both servers * one sample of my memory-exhaust exception * maildir directory listing of one mailbox on both servers * commands + outpot of manual attempt for full-replication * grep information of missing mail inside Maildir on both servers Here is my configuration from both servers. The configugration is 1:1 the same except the mail_replica server. Please note one server runs on debian 8.7 and the other one on 7.11. ---- SERVER A > # dovecot -n > # 2.2.13: /etc/dovecot/dovecot.conf > # OS: Linux 3.2.0-4-amd64 x86_64 Debian 8.7 > ---- SERVER B > # dovecot -n > # 2.2.13: /etc/dovecot/dovecot.conf > # OS: Linux 2.6.32-34-pve i686 Debian 7.11 > auth_mechanisms = plain login > disable_plaintext_auth = no > doveadm_password = **** > doveadm_port = 12345 > listen = *,[::] > log_timestamp = "%Y-%m-%d %H:%M:%S " > mail_max_userip_connections = 100 > mail_plugins = notify replication quota > mail_privileged_group = vmail > passdb { > args = /etc/dovecot/dovecot-sql.conf > driver = sql > } > plugin { > mail_replica = tcp:*.****.de > quota = dict:user::file:/var/vmail/%d/%n/.quotausage > replication_full_sync_interval = 1 hours > sieve = /var/vmail/%d/%n/.sieve > sieve_max_redirects = 25 > } > protocols = imap > replication_max_conns = 2 > service aggregator { > fifo_listener replication-notify-fifo { > mode = 0666 > user = vmail > } > unix_listener replication-notify { > mode = 0666 > user = vmail > } > } > service auth { > unix_listener /var/spool/postfix/private/auth { > group = postfix > mode = 0660 > user = postfix > } > unix_listener auth-userdb { > group = vmail > mode = 0600 > user = vmail > } > user = root > } > service config { > unix_listener config { > user = vmail > } > } > service doveadm { > inet_listener { > port = 12345 > } > user = vmail > } > service imap-login { > client_limit = 1000 > process_limit = 512 > } > service lmtp { > unix_listener /var/spool/postfix/private/dovecot-lmtp { > group = postfix > mode = 0600 > user = postfix > } > } > service replicator { > process_min_avail = 1 > unix_listener replicator-doveadm { > mode = 0666 > } > } > ssl_cert = </etc/postfix/smtpd.cert > ssl_key = </etc/postfix/smtpd.key > ssl_protocols = !SSLv2 !SSLv3 > userdb { > driver = prefetch > } > userdb { > args = /etc/dovecot/dovecot-sql.conf > driver = sql > } > protocol imap { > mail_plugins = notify replication quota imap_quota > } > protocol pop3 { > mail_plugins = quota > pop3_uidl_format = %08Xu%08Xv > } > protocol lda { > mail_plugins = notify replication quota sieve > postmaster_address = webmaster@localhost > } > protocol lmtp { > mail_plugins = notify replication quota sieve > postmaster_address = webmaster@localhost > } This is the exception which I got several times: Feb 26 16:16:39 mx dovecot: replicator: Panic: data stack: Out of memory > when allocating 268435496 bytes > Feb 26 16:16:39 mx dovecot: replicator: Error: Raw backtrace: > /usr/lib/dovecot/libdovecot.so.0(+0x6b6fe) [0x7f7ca2b0a6fe] -> > /usr/lib/dovecot/libdovecot.so.0(+0x6b7ec) [0x7f7ca2b0a7ec] -> > /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7f7ca2ac18fb] -> > /usr/lib/dovecot/libdovecot.so.0(+0x6977e) [0x7f7ca2b0877e] -> > /usr/lib/dovecot/libdovecot.so.0(+0x699db) [0x7f7ca2b089db] -> > /usr/lib/dovecot/libdovecot.so.0(+0x82198) [0x7f7ca2b21198] -> > /usr/lib/dovecot/libdovecot.so.0(+0x6776d) [0x7f7ca2b0676d] -> > /usr/lib/dovecot/libdovecot.so.0(buffer_write+0x6c) [0x7f7ca2b069dc] -> > dovecot/replicator(replicator_queue_push+0x14e) [0x7f7ca2fa17ae] -> > dovecot/replicator(+0x4f9e) [0x7f7ca2fa0f9e] -> dovecot/replicator(+0x4618) > [0x7f7ca2fa0618] -> dovecot/replicator(+0x4805) [0x7f7ca2fa0805] -> > /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x3f) [0x7f7ca2b1bd0f] > -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0xf9) > [0x7f7ca2b1cd09] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x9) > [0x7f7ca2b1bd79] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x38) > [0x7f7ca2b1bdf8] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x13) > [0x7f7ca2ac6dc3] -> dovecot/replicator(main+0x195) [0x7f7ca2f9f8b5] -> > /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xf5) [0x7f7ca2715b45] > -> dovecot/replicator(+0x395d) [0x7f7ca2f9f95d] > Feb 26 16:16:39 mx dovecot: imap(***.com): Warning: replication(***.com): > Sync failure: > Feb 26 16:16:39 mx dovecot: replicator: Fatal: master: > service(replicator): child 24012 killed with signal 6 (core dumps disabled) This is the current maildir listing on Server A # ls -la /var/vmail/*.eu/*h/Maildir/new/ > total 24 > drwx------ 2 vmail vmail 4096 Feb 27 18:12 . > drwx------ 15 vmail vmail 4096 Feb 27 21:47 .. > -rw------- 1 vmail vmail 3600 Feb 27 14:49 1488206976.M277562P25620.mail, > S=3600,W=3671 > -rw------- 1 vmail vmail 4390 Feb 27 15:17 1488208642.M513542P27111.mail, > S=4390,W=4478:2,S > -rw------- 1 vmail vmail 3577 Feb 27 16:32 1488213157.M307300P30773.mail, > S=3577,W=3648:2,S This is the current maildir listing on Server B # ls -la /var/vmail/*.eu/*h/Maildir/new/ > total 16 > drwx------ 2 vmail vmail 12288 Feb 27 16:45 . > drwx------ 15 vmail vmail 4096 Feb 27 21:47 ..

Exclude namespace from replication
by George Kontostanos 01 Mar '17

01 Mar '17

Hello list, I am using replication with dsync and I am facing some issues with shared folders. More particularly expunged message reappearing. I have searched a bit and it was suggested that shared folders should not be synced. My namespace looks like that: namespace { inbox = no list = children location = maildir:/usr/local/vhosts/mail/%%d/%%n:LAYOUT=fs:INDEX=/usr/local/vhosts/indexes/%d/%n/shared/%%u:INDEXPVT=/usr/local/vhosts/indexes/%d/%n/shared/%%u prefix = shared/%%d/%%n/ separator = / subscriptions = no type = shared } I was wondering if defining: replication_dsync_parameters = -d -N -l 30 -U -x shared Is enough. Or do I need to change the syntax of the namespace like that: namespace shared { .... .... type = shared } Thanks for your help

Preserve environment variables for doveadm
by Teodor Milkov 01 Mar '17

01 Mar '17

Hello, I noticed there are ways to instruct various dovecot processes to preserve particular environment variables. One way is to use import_environment in dovecot.conf and yet another is to export DOVECOT_PRESERVE_ENVS variable – both can contain space delimited list of variables to preserve. I found report that this is supposed to work for dsync: http://www.dovecot.org/list/dovecot/2012-October/138659.html Unfortunately I can't it to work for "doveadm quota recalc". Is it supposed to work or am I doing something wrong? I did strace on the doveadm process and noticed it does exec() doveconf which in turn does exec() doveadm again. If I replace doveconf with a shell script which exports my environment variables then they become available to doveadm: # cat /dovecot/bin/doveconf.wrapper #!/bin/sh export LD_PRELOAD='dovecot-preload.so' exec /dovecot/bin/doveconf.orig "$@"
