I tried to contribute by updating the wiki docs, but it belched when I saved the update: TextCha: Wrong answer! Go back and try again... Here's what I tried to add at the bottom (in text mode) The {{{deliver_log_format}}} specifies logging details for a successful delivery. (versions>2.0.13: leaving it empty will disable this logging). See example configuration files for a full list of variable expansion: {{{ delivery_log_format = msgid=%m: %$ }}} Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Umask of Homedir
by Francisco Wagner C. Freire 20 Apr '11

20 Apr '11

Hello, I following the instrucions of: http://wiki2.dovecot.org/SharedMailboxes/Permissions When the user receive the first mail, dovecot create the directory structure always using mode 0700, if i change the permission of the user maildir all new mails arrived get the correct umask: dovecot: lmtp(24960, *): Debug: Namespace INBOX.: Using permissions from .../maildir: mode=0770 The problem is: I need to all accounts have the permission 0770. Tried to use the option: mail_access_groups but doesn't work at all when the first creation of the user path. "For example a simple way to set up shared mailbox access for all system users is to make all mail dirs/files 0770/0660 mode and owned by group "sharedmail" and then set mail_access_groups=sharedmail. Using more fine grained groups of course leaks less mail data in case there's a security hole in Dovecot" Is a bug? My dovecot version: doveconf -n # 2.0.12 (811a6d173bb2): /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.1 Access groups: mail_access_groups = _sysadms Thanks and sorry for bad english.

[Dovecot] Logging commands
by Luciano Mannucci 20 Apr '11

20 Apr '11

Hello all, is there a way to make dovecot log the commands it gets from its clients both in imap and pop3? I need to log when messages are deleted so I can tell to the customer when and from which IP address his/her mailbox was emptied. I'm trying to track down problems with M$ Windows Live Mail clients that seem to loose messages now and then. Luciano. -- /"\ /Via A.

[Dovecot] help with MYSQL and dovecot
by Littlefield, Tyler 20 Apr '11

20 Apr '11

Hello all: I understand I can't provide to much information; at the moment, I do not have dovecot installed. Here is the problem. I started out running saslauthd, but there appears to be a problem where memory isn't freed after someone fails to authenticate, which leads to a huge dos attack. I hit this problem a couple of times, and it looks like some poor lonely soul (or bot, as it may be) with no life decided to go after my server again today. I had previously tried to configure dovecot, but I have an odd mysql setup, so it was particularly dificult. I am leaving out of town tomorrow afternoon and will not have internet, so I want to make sure this is going to be running as it should be. Here is the info from the dovecot configuration file for mysql. It was giving an error about "username" when I tried to run this. If someone can't spot the problem from this, I will disable courier and reinstall dovecot tonight so I can get the exact error. userdb static { args = uid=vmail gid=vmail home=/home/vmail/%d/%n password_query = select email as user, password,\ home AS userdb_home, uid AS userdb_uid, gid AS userdb_gid \ from users where email = '%u' user_query = \ SELECT home AS userdb_home, uid AS userdb_uid, gid AS userdb_gid \ FROM users WHERE email = '%n'; } And here is the describe for both tables: mysql> describe users; +----------+-------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +----------+-------------+------+-----+---------+-------+ | email | varchar(80) | NO | PRI | NULL | | | password | varchar(20) | NO | | NULL | | +----------+-------------+------+-----+---------+-------+ 2 rows in set (0.00 sec) -- mysql> describe domains; +--------+-------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +--------+-------------+------+-----+---------+-------+ | domain | varchar(50) | NO | PRI | NULL | | +--------+-------------+------+-----+---------+-------+ 1 row in set (0.01 sec) Thanks, Ty

[Dovecot] LDAP Authentication with multiple independent domains
by Alex Cherniak 20 Apr '11

20 Apr '11

Is it possible to authenticate users against multiple independent AD domains? In my dovecot-ldap.conf I entered two hosts: hosts = host1 host 2 auth_bind_userdn = %d\%n ldap_version = 3 base = cn=users,dc=%d,dc=net auth_bind = yes but OpenLDAP seems to stop authentication as soon as the first host succeeds or fails. I also tried to configure trust between the two, but it didn't work either. Please help...

[Dovecot] LDA null logging patch
by Joseph Tam 20 Apr '11

20 Apr '11

I don't really need logging of successful local deliveries since the MTA provides enough data. I can't get rid of LDA delivery logs by setting deliver_log_format = All this does is produce an empty log message e.g. Apr 16 01:22:05 dserver dovecot: lda(user): Timo, would you consider inclusion of this patch which will skip logging deliveries if deliver_log_format is empty: --- src/lib-lda/mail-deliver.c~ Sat Apr 16 01:27:23 2011 +++ src/lib-lda/mail-deliver.c Sat Apr 16 01:29:05 2011 @@ -100,2 +100,5 @@ + if (!(ctx->set->deliver_log_format) || !(*ctx->set->deliver_log_format)) + return; + va_start(args, fmt); Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Debug new emails?
by Beto Moreno 20 Apr '11

20 Apr '11

Hi guys. I would like to debug all the new emails arrive to the users mailbox, I have some issue with 1 users that claim that is losing some important emails. The issue that I are not logging to much info in dovecot, I had read the mail_log plugin wiki is not difficult to setup. I want to see went the users receive the new emails, because postfix have the log that say" "sent" from the envelop to the issue user, but I the user say that he didn't receive the email, check his emails and is true I didn't see those 2 emails that postfix send to the user mailbox. I check my spam server and is not blocking that envelop, the spam is not causing this. I'm using Centos 5.4 Postfix 2.3.x Dovecot 1.0.x,but reading mail_log plugin say that we need 1.2.x, can I still use this plugin or I have other options? Thanks!!!

[Dovecot] expire-tool skipping mailbox
by Alex Reinhart 20 Apr '11

20 Apr '11

Hello, I have dovecot set up with expire-tool to nuke Junk messages greater than 30 days old. On a server with many user accounts, it seems to work on most of them. However, on my user account, expire-tool skips my Junk folder entirely, despite it containing messages from January of this year. Here is the expire-tool --test output: Info: alex(a)scienceforums.net/Junk: timestamp 1284027481 (Thu Sep 9 05:18:01 2010) -> 1304023056 (Thu Apr 28 15:37:36 2011) Then it skips to the next mailbox. (Note that I intentionally set the timestamp back to force it to consider my mailbox.) I don't understand why it doesn't want to expunge my 2700 junk messages when it will expunge several thousand in other accounts happily. The expire plugin has been enabled for probably over a year, so all of the messages should be tracked. My only hypothesis is that it has something to do with variables in the mail_location; however, mail_location should be overridden by a user_query, though that contains variables too. Would this account for the issue? It seems unlikely, since other users on the server work just fine. dovecot -n output for the interested: # 1.2.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-24-server x86_64 Ubuntu 10.04.2 LTS ext3 base_dir: /var/run/dovecot/ log_timestamp: %Y-%m-%d %H:%M:%S protocols: managesieve imaps pop3s listen(default): *:143 listen(imap): *:143 listen(pop3): *:110 listen(managesieve): * ssl_listen(default): *:993 ssl_listen(imap): *:993 ssl_listen(pop3): *:995 ssl_listen(managesieve): login_dir: /var/run/dovecot//login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login first_valid_uid: 150 last_valid_uid: 150 mail_privileged_group: mail mail_location: maildir:/var/vmail/%d/%u mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugins(default): quota imap_quota expire mail_plugins(imap): quota imap_quota expire mail_plugins(pop3): quota expire mail_plugins(managesieve): mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 mail_plugin_dir(managesieve): /usr/lib/dovecot/modules/managesieve lda: mail_plugins: quota sieve expire postmaster_address: postmaster(a)xyloid.org sendmail_path: /usr/lib/sendmail auth_socket_path: /var/run/dovecot/auth-master sieve_global_path: /etc/dovecot/sieve.global auth default: user: nobody passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 432 user: vmail group: mail plugin: quota: dict:user::proxy::quotadict quota_rule: *:storage=1G quota_rule2: Trash:storage=10%% quota_rule3: Junk:ignore sieve: /var/vmail/%d/%n/dovecot.sieve expire: Trash 7 Trash/* 7 Junk 30 expire_dict: proxy::expire dict: quotadict: mysql:/etc/dovecot/dovecot-dict-quota.conf expire: mysql:/etc/dovecot/dovecot-dict-expire.conf And dovecot-dict-expire.conf: connect = host=localhost dbname=mail user=mail password=[password] map { pattern = shared/expire/$user/$mailbox table = expires value_field = expire_stamp fields { username = $user mailbox = $mailbox } } Thanks. - Alex Reinhart

[Dovecot] sieve-test ignores precedence and other for vacation
by Burckhard Schmidt 20 Apr '11

20 Apr '11

Hello, I'm using pigeonhole-0.2.3, it works fine. I tried to verify some build in checks of vacation concerning precedence or auto-submitted header lines. It looks like sieve-test ignores header lines like Auto-Submitted: auto-submitted Precedence: bulk Return-Path: MAILER-DAEMON@... if I have a vacation script like require ["vacation", "regex", "fileinto", "variables", "envelope"]; if allof (header :regex ["to"] ["address1", "address2"], header :matches "to" "*") { vacation :days 7 : ... "text"; } The email to test contains a line like Precedence: bulk or Return-Path: <MAILER-DAEMON@...> or Auto-Submitted: yes sieve-test -D -C script.sieve mail I get Performed actions: * send vacation message: => seconds : 604800 ... text of vacation message END MESSAGE Implicit keep: * store message in folder: INBOX sieve-test(root): Info: final result: success -- Regards --- Burckhard Schmidt
