Trouble viewing Inbox via IMAP Client
by Peter Cook 02 Sep '14

02 Sep '14

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. The problem I am having is that I can send and receive mail fine, but when I try to view my Inbox in an IMAP client like Thunderbird, I can only view sent mail and trash. Here is the result of my dovecot -- version and dovecot -n --version 2.0.9 dovecot -n # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-431.el6.x86_64 x86_64 CentOS release 6.5 (Final) ext4 auth_debug = yes auth_debug_passwords = yes disable_plaintext_auth = no mail_location = maildir:/var/mail/vmail/%d/%n/ mbox_write_locks = fcntl passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } passdb { driver = pam } protocols = imap pop3 service auth { group = postfix unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } user = postfix } ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } userdb { driver = passwd }

dsync-server couldn't create .dovecot-sync.lock file
by Listas＠Adminlinux 02 Sep '14

02 Sep '14

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. How can I avoid this error message? ================================================================================ root@myserver2:/root# doveconf -n # 2.2.9: /etc/dovecot/dovecot.conf # OS: Linux 3.13.0-30-generic x86_64 Ubuntu 14.04.1 LTS auth_master_user_separator = * auth_mechanisms = plain login auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@= auth_worker_max_count = 1 disable_plaintext_auth = no doveadm_password = secret doveadm_port = 12345 listen = myserver2.mydomain.com log_path = /var/log/dovecot.log login_greeting = MAILBOX IMAP/POP3 server mail_fsync = never mail_gid = dovemail mail_plugins = " notify replication quota" mail_uid = dovemail passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } passdb { args = /etc/dovecot/dovecot-sql-master.conf.ext driver = sql master = yes pass = yes } plugin { mail_replica = tcp:myserver1.mydomain.com:12345 quota = dict:User quota::file:/var/lib/imap/%n/dovecot-quota quota_rule = *:storage=1GB } protocols = imap pop3 lmtp service auth-worker { user = $default_internal_user } service auth { client_limit = 1024 process_limit = 1 process_min_avail = 1 } service doveadm { inet_listener { port = 12345 } } service imap { process_limit = 1024 process_min_avail = 1 } service lmtp { inet_listener { address = myserver2.mydomain.com port = 24 } process_limit = 256 process_min_avail = 1 } service pop3-login { inet_listener pop3 { address = myserver2.mydomain.com port = 110 } } service pop3 { process_limit = 256 process_min_avail = 1 } service replicator { process_min_avail = 1 } ssl = no userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol imap { imap_client_workarounds = tb-extra-mailbox-sep imap_idle_notify_interval = 2 mins imap_max_line_length = 64 k mail_max_userip_connections = 50 mail_plugins = " notify replication quota imap_quota" } protocol lmtp { mail_fsync = optimized mail_plugins = " notify replication sieve quota" } protocol pop3 { mail_plugins = " notify replication quota" } ================================================================================ Thanks! -- Thiago Henrique

Master user and non-plaintext auth does not work
by SATOH Fumiyasu 01 Sep '14

Hi, I want to use CRAM-MD5 or DIGEST-MD5 (non-plaintext) authentication for master users, but Dovecot 2.2.13 rejects it with the following log: Sep 1 06:18:08 localhost dovecot: auth: passwd-file(masteruser,10.0.1.20,master,<ZA1s9/oBgAAKAAEU>): Master user logging in as u0001 Sep 1 06:18:08 localhost dovecot: auth: cram-md5(u0001(a)example.jp,10.0.1.20,<ZA1s9/oBgAAKAAEU>): password mismatch Sep 1 06:18:10 localhost dovecot: imap-login: Disconnected (auth failed, 1 attempts in 2 secs): user=<u0001(a)example.jp>, method=CRAM-MD5, rip=10.0.1.20, lip=10.0.103.100, secured, session=<ZA1s9/oBgAAKAAEU> PLAIN and LOGIN are OK: Sep 1 06:20:34 localhost dovecot: auth: passwd-file(masteruser,10.0.1.20,master,<SpwmAPsBgwAKAAEU>): Master user logging in as u0001 Sep 1 06:20:34 localhost dovecot: imap-login: Login: user=<u0001(a)example.jp>, method=PLAIN, rip=10.0.1.20, lip=10.0.103.100, mpid=23743, secured, session=<SpwmAPsBgwAKAAEU> Sep 1 06:20:34 localhost dovecot: imap(u0001(a)example.jp): SpwmAPsBgwAKAAEU: Connection closed in=13 out=663 I have the following configuration in my dovecot.conf: auth_mechanisms = plain login cram-md5 digest-md5 disable_plaintext_auth = yes auth_master_user_separator = % passdb { driver = passwd-file args = /etc/dovecot/passwd.masterusers master = yes pass = yes } # don't work too #passdb { # driver = checkpassword # args = /opt/osstech/etc/dovecot/checkpassword.masterusers # master = yes # pass = yes #} passdb { driver = ldap args = /etc/dovecot/dovecot-ldap.conf.ext } Is this a bug or a restriction of Dovecot? -- -- Name: SATOH Fumiyasu @ OSS Technology Corp.

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
