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

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.

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

mail_location hashing & lowercasing?
by Ralf Hildebrandt 31 Aug '14

31 Aug '14

Currently, I'm using mail_location = mdbox:/var/spool/mail/%Ld/%Ln/mdbox Now I want to add a partitioning (so I don'T have all directories in one single directory), but can't find the right syntax: mail_location = mdbox:/var/spool/mail/%Ld/<HASHING HERE>/%Ln/mdbox It seems like I'd need to use %N (new hash) on %Ln and then take a substring of that. %2NLn 2 Characters of the %N hash of %Ln (the lowercase username) But this gives me a verbatim "Ln" on the path! -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Marc Schiffbauer Aufsichtsratsvorsitzender: Florian Kirstein

Need help to compile and install a minimal dovecot imap plugin
by Stefan Arentz 31 Aug '14

31 Aug '14

I am trying to create a plugin that adds a new IMAP capability. So far I have this: const char *foo_plugin_version = DOVECOT_ABI_VERSION; static struct module *foo_module; static imap_client_created_func_t *next_hook_client_created; static void foo_client_created(struct client **client) { str_append((*client)->capability_string, " XFOO"); if (next_hook_client_created != NULL) { next_hook_client_created(client); } } void foo_plugin_init(struct module *module) { i_info(“init”); foo_module = module; next_hook_client_created = imap_client_created_hook_set(foo_client_created); } void foo_plugin_deinit(void) { i_info(“deinit”); imap_client_created_hook_set(next_hook_client_created); } const char foo_plugin_binary_dependency[] = "imap”; On Fedora 20, with the dovecot and dovecot-devel packages installed, I compile this with: cc -Wall -shared -fPIC -DHAVE_CONFIG_H -I/usr/include/dovecot -o lib20_foo_plugin.so foo-plugin.c And then install with: sudo cp lib20_foo_plugin.so /usr/lib64/dovecot/ (I also have mail_plugin_dir = /usr/lib64/dovecot in 10-mail.conf) I enable this plugin in /etc/dovecot/conf.d/20-imap.conf with: protocol imap { mail_plugins = $mail_plugins foo } But … nothing happens. No warnings, no errors, no crashes. How do I debug this? Am I missing something obvious? Does the naming of the plugin matter? S.

Misleading error message when case-insensitive file/dir names from config files clash with case-sensitive file system.
by Info Akra 30 Aug '14

30 Aug '14

Hi, Is it noted somewhere that Dovecot (v 2.0.9) doesn’t use case in directory names in its config-files? I found that out the hard way (i.e. a week of debugging)!! in /etc/dovecot/conf.d/10-master.conf, the line: unix_listener /var/spool/postOut/auth/dovecot-auth { creates a: Jul 29 22:15:58 server dovecot: master: Error: service(auth): unlink(/var/run/dovecot/) failed: Is a directory but unix_listener /var/spool/postout/auth/dovecot-auth { works just fine (with matching case changes on the directory names themselves). That’s on running on Ubuntu 12.04.4 TLS, standard installation from apt-get, in cooperation with Postfix 2.0.9. — Hugo

Dsync setup... help needed
by Sinergizmas Sin ergizmas 30 Aug '14

30 Aug '14

Hello, I tried to implement Dsync (doveadm version 2.2.10) following https://www.evilcoder.org/2014/08/22/automatic-replication-with-dovecot/ but had no luck. SSH commands working quite well, but I need to respond more quickly. So TCP looks promising. I have Centos 6, Dovecot 2.2.10. I did everything that is written there, but after I restart dovecot doesn't sync. Then i ran netstat command but no service listen to port 12345 also. Iptables service are of in testing scenario...

Migrating courier to dovecot
by Patrick Lion 29 Aug '14

29 Aug '14

Hi, i want to migrate the following setup: postfix / courier-{imap/s,pop3/s,authlib} / maildrop / mysql I´m using the maildir format and quotas as well. My target is the following setup: postfix / dovecot / some sort of quota respecting lda / mysql What i`ve done already: SQL-Implementation for dovecot, login process and also sending mails via auth-userdb is already working. Quotas are read out from database and working. Before i mention my problems while implementing, here is the config im using at this time: # 2.2.13: /etc/dovecot/dovecot.conf # OS: Linux 3.14.14-gentoo x86_64 Gentoo Base System release 2.2 auth_mechanisms = plain login auth_socket_path = /var/run/dovecot/auth-userdb auth_verbose = yes disable_plaintext_auth = no info_log_path = syslog login_log_format_elements = user=<%u> method=%m ip=%r mpid=%e mail_debug = yes mail_location = maildir:.maildir mail_plugins = quota namespace inbox { inbox = yes location = .maildir 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 = INBOX. separator = . } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { args = /etc/dovecot/dovecot-sql.conf.ext quota = maildir:User quota quota_rule = %u quota_rule2 = trash:storage=+150M quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=80%% quota-warning 80 %u } service auth { unix_listener /var/spool/postfix/private/auth { group = mail mode = 0660 user = postfix } unix_listener auth-userdb { group = mail mode = 0660 user = postfix } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0666 user = postfix } } ssl_cert = </etc/ssl/dovecot/server.pem ssl_key = </etc/ssl/dovecot/server.key userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol imap { mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota } grep -v '^ *$#.*$\?$' dovecot-sql.conf.ext driver = mysql connect = host=127.0.0.1 dbname=postfix user=postfix password=thereisone default_pass_scheme = MD5-CRYPT password_query = \ SELECT username, password \ FROM mailbox WHERE username = '%u' user_query = \ SELECT concat('/', home, user, '/', destinationname) AS home, uid, gid, \ concat('*:storage=', round(quota / 1000 * 1.024)) AS quota_rule \ FROM mailbox WHERE username = '%u' Where user is the row where the admin-panel user is stored and username is the mbox-user. My problem is the LDA, with dovecot-lda im having the uid / gid trouble and i really dont want to suid oder sudo it. dovecot-lmtp just gives me status=deferred (host xx.xx[/var/run/dovecot/lmtp] said: 451 4.3.0 <box(a)xx.xx> Temporary internal error (in reply to end of DATA command)) Postfix virtual is working as well as maildrop, but no dovecot-implementation wants to, i also didnt find anything about the error above, except a bug in v2.2.2 and a google groups thread where users are just blaming each others for nothing .. I want to use a dovecot lda/lmtp because the quota settings for trash-folders are very nice and reducing my support times but im stuck at getting one of the dovecot-LDAs to work. Let me know if you need any additional information. Any help is greatly appreciated! -- Viele Grüße / Best regards Patrick
