Trying Dovecot Replication with dsync
by Listas＠Adminlinux 04 Sep '14

04 Sep '14

Hi, I have a failover cluster for mail server with: Ubuntu12.04 + DRBD (for block replication) + Ext4 filesystem + Dovecot-2.0.19-2 with Mdbox It works fine with ~50k accounts. My cluster design: http://adminlinux.com.br/cluster_design.txt I plan to test Dovecot Replication with dsync to build an active/active cluster with load balancing. Can anyone direct me to some literature? A tutorial for example. I'm installing a cluster (for tests) with Ubuntu 14.04 + Ext4 filesystem (without Drbd) + Dovecot-2.2.9-1ubuntu2.1. My conf is in: http://adminlinux.com.br/replication-doveconf.txt I'm following this doc http://wiki2.dovecot.org/Replication but I'm getting some errors: 1) Aug 14 15:39:34 ceph1 dovecot: imap(account=domaintest.com): Error: open(/var/run/dovecot/replication-notify-fifo) failed: Permission denied What is the correct perms for /var/run/dovecot/replication-notify-fifo ? Currently: # ll /var/run/dovecot/replication-notify-fifo prw------- 1 root root 0 Aug 14 15:57 /var/run/dovecot/replication-notify-fifo| 2) Aug 14 16:02:34 ceph1 dovecot: dsync-server(account=domaintest.com): Error: Couldn't create lock /var/lib/imap/account=domaintest.com/.dovecot-sync.lock: No such file or directory Aug 14 16:02:34 ceph1 dovecot: dsync-local(account=domaintest.com): Error: Couldn't create lock /var/lib/imap/account=domaintest.com/.dovecot-sync.lock: No such file or directory In my production cluster, it is automatically created by dovecot when the user performs the first login: /var/lib/imap/<account> for INDEX /var/spool/imap/<account> for Mdbox Thanks! -- Thiago Henrique

Some Dsync Replication Errors

This one is fairly common: Sep 3 12:58:25 molecular dovecot: dsync-server(user(a)domain.org): Warning: Failed to do incremental sync for mailbox INBOX, retry with a full sync (Modseq 100298 no longer in transaction log) These two I ran into yesterday and today: Sep 2 11:13:32 molecular dovecot: dsync-server(user2(a)domain2.org): Error: Timeout during state=slave_recv_last_common Sep 3 12:52:08 molecular dovecot: dsync-server(user3(a)domain3.org): Error: read(remote.mailserver.net) failed: EOF Configs: mail_plugins = notify replication service doveadm { inet_listener { port = 1234 } } service replicator { process_min_avail = 1 unix_listener replicator-doveadm { mode = 0600 } } service aggregator { fifo_listener replication-notify-fifo { user = vmail mode = 0600 } unix_listener replication-notify { user = vmail mode = 0600 } } plugin { mail_replica = tcp:sub.domain.org:1234 } And doveconf -n: [root@molecular dovecot]# doveconf -n # 2.2.13.16 (94835dd63163): /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-431.el6.x86_64 x86_64 Scientific Linux release 6.5 (Carbon) ext4 auth_mechanisms = plain login auth_verbose = yes auth_verbose_passwords = plain deliver_log_format = msgid=%m: from=%f: %$ doveadm_password = secret doveadm_port = 1234 mail_debug = yes mail_home = /vmail/%d/%n/home mail_location = maildir:/vmail/%d/%n mail_plugins = notify replication 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 duplicate namespace { inbox = yes location = prefix = separator = / type = private } passdb { args = /etc/dovecot/dovecot-mysql.conf driver = sql } plugin { mail_log_fields = box msgid from flags mail_replica = tcp:sub.domain.org:1234 sieve = /vmail/%d/%n/home/.dovecot.sieve sieve_dir = /vmail/%d/%n/home/sieve } protocols = imap pop3 lmtp sieve service aggregator { fifo_listener replication-notify-fifo { mode = 0600 user = vmail } unix_listener replication-notify { mode = 0600 user = vmail } } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { group = vmail mode = 0660 user = vmail } unix_listener auth-userdb { mode = 0660 user = vmail } user = root } service doveadm { inet_listener { port = 1234 } } service imap-login { process_min_avail = 3 service_count = 0 vsz_limit = 0 } service managesieve-login { inet_listener sieve { port = 4190 } process_min_avail = 0 service_count = 1 vsz_limit = 64 M } service replicator { process_min_avail = 1 unix_listener replicator-doveadm { mode = 0600 } } ssl_cert = </etc/postfix/ssl/sub.domain.org.pem ssl_key = </etc/postfix/ssl/domain.key userdb { args = /etc/dovecot/dovecot-mysql.conf driver = sql } protocol lda { hostname = sub.domain2.org mail_plugin_dir = /usr/lib64/dovecot/ mail_plugins = sieve postmaster_address = postmaster(a)domain2.org } protocol imap { imap_idle_notify_interval = 24 mins mail_max_userip_connections = 60 } protocol sieve { mail_max_userip_connections = 10 managesieve_implementation_string = Dovecot Pigeonhole managesieve_logout_format = bytes=%i/%o managesieve_max_line_length = 65536 } -- --Asai

Insert custom header in Mail logger plugin
by Bruno Galindro da Costa 03 Sep '14

03 Sep '14

Is it possible to log a message custom header through Mail logger plugin or other method? It seems that there are a fixed number of info that is configurable via mail_log_fields (http://wiki2.dovecot.org/Plugins/MailLog) .. My custom header is X-VERTICAL-IP-Quarantine-ID and I want a log event like this one: Aug 27 09:48:13 imap dovecot: imap(user@domain): copy from INBOX: box=SPAM, uid=213, *X-VERTICAL-IP-Quarantine-ID=u7cnUqYDPA9a*, msgid=< 0.0.D7.290.1CFC155CE887302.0(a)etm2.com>, size=26481, vsize=26949, from==?UTF-8?Q?Dafiti=20-=20Parceiros?= <aaa@domain>, subject==?UTF-8?Q?Sapatos=20com=2040%OFF?==?UTF-8?Q?!=20Apro?=? =?UTF-8?Q?veite!?= -- Att.

Setup sieve failed
by Christian Vielhauer 03 Sep '14

03 Sep '14

Hi, I try to setup sieve but I have some trouble. Using dovecot 2.2.9 on Ubuntu 14.04.1 LTS. I replaced my correct domain with „domain.tld“. I am able to create sieve scripts using SOGo. The scripts are created in my mailbox. For example in /var/www/kunden/mail/domain.tld/testuser/sieve/sogo.sieve I have the following script and in same ~/sieve folder is a subdirectory available that’s called "tmp“: ~/sieve ~/sieve/tmp require ["vacation"]; if allof ( not exists ["list-help", "list-unsubscribe", "list-subscribe", "list-owner", "list-post", "list-archive", "list-id", "Mailing-List"], not header :comparator "i;ascii-casemap" :is "Precedence" ["list", "bulk", "junk"], not header :comparator "i;ascii-casemap" :matches "To" "Multiple recipients of*" ) {vacation :days 1 :addresses [„testuser(a)domain.tld"] text: This is a vacation test message. Please ignore. . ; } Now I open /var/log/mail.err and I can see the following: Sep 3 17:50:09 mail dovecot: imap(testuser(a)domain.tld): Error: stat(/var/www/kunden/mail/domain.tld/testuser/.dovecot.sieve/tmp) failed: Not a directory I try to create ~/.dovecot.sieve folder, but this file exists and is a symlink. 0 lrwxrwxrwx 1 vmail vmail 16 Sep 3 18:14 .dovecot.sieve -> sieve/sogo.sieve I think I have some miss configuration because i don’t receive any vacation reply when I send mail to my testuser.

quota for subfolder with prefix=INBOX.
by Jogi Hofmüller 03 Sep '14

03 Sep '14

Hi all, We use prefix=INBOX. in order to keep things as they were on the old server. Now I started playing with quota and have trouble getting the additional quota for Trash and/or Junk working. My expectation was that once a user is over quota and moves email to trash sh/e should be able to receive new email again. That's what I cannot get to work with our setup. Attached you find the config that I thought should be working. The numbers are ridiculously low but that's just for testing. Here is some output from doveadm doveadm quota get -u user Quota name Type Value Limit % User quota STORAGE 5422 5120 105 User quota MESSAGE 18 - 0 doveadm mailbox status -u user "messages vsize" "*" INBOX messages=13 vsize=3147033 doveadm mailbox status -u user "messages vsize" "INBOX.*" INBOX.Drafts messages=0 vsize=0 INBOX.Sent messages=0 vsize=0 INBOX.Trash messages=5 vsize=2475790 INBOX.Junk messages=0 vsize=0 Regards, -- j.hofmüller We are all idiots with deadlines. - Mike West

Hi, I just moved the dovecot maildir location for all virtual users to another location. I moved everything from /var/mail/vhosts/%d/%n to /var/vmail/%d/%n/maildir Everything seem to be fine except of one recurring error: Sep 2 10:16:09 mx0 dovecot: lmtp(13226, sv_bogies(a)neurohr.at) Error: file_dotlock_open(/var/mail/vhosts/domain.at/michael/.dovecot.lda-dupes) failed: No such file or directory Sep 2 13:31:27 mx0 dovecot: lmtp(16248, sv_bogies(a)neurohr.at) Error: file_dotlock_open(/var/mail/vhosts/domain.at/michael/.dovecot.lda-dupes) failed: No such file or directory So Dovecot is looking in the old path.

Trouble viewing Inbox via IMAP Client

Hello, I have been having trouble with this issue for quite some time now. Here is my environment: CentOS 6.5, Postfix built with PGSQL support, PFA, and dovecot.

dsync-server couldn't create .dovecot-sync.lock file

My dovecot stores users' emails on /var/spool/imap/<user> and stores the messages index on /var/lib/imap/<user>. I have many users who do not yet have their userdb_home directories created on the server, because that is created at the time of first login. I'm testing dsync for replication and have seen the following error: dsync-server(<user>): Error: Couldn't create lock /var/lib/imap/<user>/.dovecot-sync.lock: No such file or directory The /var/lib/imap/<user> directory does not exist yet and I think this is the cause.
