[Dovecot] Username bug in '%%' variables selects
by Victor 06 Apr '12

06 Apr '12

Hi! Forgive my bad English. I trying to set up shared folders, but I can't. I shared INBOX of 'victor(a)domain.com' for 'victor(a)testmail.domain.com' There is my debugging results: doveadm acl debug -u victor(a)testmail.domain.com INBOX.shared.victor(a)domain.com. doveadm(victor(a)testmail.domain.com): Error: Couldn't create namespace 'INBOX.shared.' for user victor@domain: userdb didn't return a home directory, but mail_location used it (%h): maildir:%h That's I seen in logs: auth-worker: Debug: sql(victor@domain): SELECT CONCAT('/var/spool/mail/', SUBSTRING_INDEX(email, '@', -1), '/', SUBSTRING_INDEX(email, '@', 1)) as home from `users` WHERE email='victor@domain' What happened with my username? 'victor@domain' is not correct value. My config: namespace { inbox = yes location = prefix = INBOX. separator = . type = private } namespace { hidden = no list = yes location = maildir:%%h prefix = INBOX.shared.%%u. separator = . subscriptions = no type = shared } password_query = \ SELECT email as username, password \ FROM users WHERE email = '%u' user_query = SELECT CONCAT('/var/spool/mail/', SUBSTRING_INDEX(email, '@', -1), '/', SUBSTRING_INDEX(email, '@', 1)) as home from `users` WHERE email='%u' Please, help me! -- Best regards, Victor

I just installed the 2.1.3 version of dovecot. When I telnet to my dovecot linux server on the imap port (143) and try to login I get the error "No [UNAVAILABLE] Temporary authentication failure" on the telnet display and dovecot: auth: Error: ldap(bhammond_test(a)131.103.212.38,128.121.121.193): ldap_search(base=uid=bhammond_test(a)131.103.212.38,ou=users,dc=aspect filter=(&(objectClass=posixAccount)(productFeature=mail))) failed: No such object in the /var/log/maillog.

[Dovecot] dovecot and unison
by FZiegler 05 Apr '12

05 Apr '12

I am successfully using dovecot purely as a personal local mail store on my desktop. (There is only one account, and it's only ever accessed by local mail clients on the machine. The point is to have a common store I can use with any client; plus, I prefer dovecot's Mailbox storage to Thunderbird's mboxes.) Now I'd like if possible, to replicate this setup on my laptop and keep both in sync with unison (http://www.cis.upenn.edu/~bcpierce/unison/) which I am already using to sync much of my home dir about once a day. I found at least one positive message regarding this topic (http://dovecot.org/list/dovecot/2010-April/048092.html) but I feel I could use some more advice. Namely, which of the ancillary files should I be syncing (or perhaps deleting before sync)? In addition to the mails themselves I'm seeing: -rw------- 1 fz 501 13 Apr 1 17:10 dovecot-keywords -rw------- 1 fz 501 2483 Apr 1 17:10 dovecot-uidlist -rw------- 1 fz 501 1040 Mar 29 14:50 dovecot.index -rw------- 1 fz 501 44032 Apr 1 17:10 dovecot.index.cache -rw------- 1 fz 501 9772 Apr 1 17:10 dovecot.index.log and at the top level (in .local/var/Maildir/): -rw------- 1 fz 501 8 Apr 1 17:10 dovecot-uidvalidity -r--r--r-- 1 fz 501 0 Apr 1 17:10 dovecot-uidvalidity.4efb323d -rw------- 1 fz 501 3288 Apr 1 17:10 dovecot.mailbox.log -rw------- 1 fz 501 4104 Mar 28 10:53 dovecot.mailbox.log.2 -rw------- 1 fz 501 5114 Apr 1 17:10 subscriptions In my naive trials I ended up at least once in a situation where Thunderbird would not see some subfolders (even though they were there). That's since fixed but I guess my question is, what's the safe recommended way to not have this happen? Thanks, FZiegler

[Dovecot] Dovecot allows creation of folders outside of a user's directory
by Christoph Bußenius 05 Apr '12

05 Apr '12

Hi, in our dovecot 2.0 setup with shared folders, users can make dovecot create directories outside their mail directory. Which is a bit scary imho. The following command: . create inbox.shared.abc123 or even . create "inbox.shared.strange &ANY- characters" -- even though it will fail with a "permission denied" error -- will create a directory like "/mail/users/strange &ANY- characters". That directory will only contain a subdirectory "Maildir" and therein dovecot-acl-list. I think basically the reason for this behaviour is that Dovecot checks whether the directory has enough ACLs for the user to access it, and auto-creates the directory in the process. Is there way to avoid this auto-creation - or maybe a way to make Dovecot check whether the directory name is an existing username? Here's a config to reproduce this: # 2.0.19: /usr/local/dovecot/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-35-server x86_64 Ubuntu 10.04.4 LTS auth_username_format = %Ln disable_plaintext_auth = no mail_gid = vmail mail_home = /mail/users/%u mail_location = maildir:~/Maildir mail_plugins = " acl" mail_uid = vmail maildir_very_dirty_syncs = yes namespace default { inbox = yes location = prefix = INBOX. separator = . type = private } namespace sharedns { inbox = no list = children location = maildir:/mail/users/%%u/Maildir prefix = INBOX.shared.%%u. separator = . subscriptions = no type = shared } passdb { args = /usr/local/dovecot/etc/dovecot/users driver = passwd-file } plugin { acl = vfile:/usr/local/dovecot/etc/dovecot/global-acls:cache_secs=300 acl_shared_dict = file:/mail/vmail/shared-mailboxes.db } service auth { unix_listener auth-userdb { group = vmail mode = 0660 } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem syslog_facility = local6 userdb { args = /usr/local/dovecot/etc/dovecot/users driver = passwd-file } protocol lmtp { mail_plugins = " sieve" } protocol imap { imap_client_workarounds = tb-extra-mailbox-sep mail_plugins = " acl imap_acl" } Content of the "users" file looks like this: user1:{plain}(hidden):::user1:/mail/users/user1:: user2:{plain}(hidden):::user2:/mail/users/user2:: testuser:{plain}(hidden):::testuser:/mail/users/testuser:: Cheers, Christoph -- Christoph Bußenius Rechnerbetriebsgruppe der Fakultäten Informatik und Mathematik Technische Universität München +49 89-289-18519 <> Raum 00.05.055 <> Boltzmannstr. 3 <> Garching

[Dovecot] problem to configuration dovecot and postfix
by Akihiko Sato 05 Apr '12

Hi, I'm having a problem with dovecot and postfix. I'm using a dovecot version 2.0.13. Postfix (Version: 2.8.5) config is changed according to the http://wiki2.dovecot.org/LDA/Postfix: I have thought to build a virtual user and virtual mailbox, and use the functionality of the Sieve. However, when the test set, the mail not received the mailbox. Record that there was a "temporary failure" in the log of Postfix. It delivered and to change the "virtual" to "dovecot", I think that's a matter of dovecot. To ensure that mail is delivered as intended, will How do I?

[Dovecot] Dovecot upgrade from 1.2.x to 2.0.x: roundcube/squirrelmail sent folder doesn't work any more
by Gerhard Wiesinger 05 Apr '12

05 Apr '12

Hello, After upgrading from 1.2.x to 2.0.x I'm having problems using sent folder in Webmail applications like roundcube mail and squirrelmail. Relevant config dovecot.conf: mail_location = mbox:~:INBOX=/var/mail/%u Different LIST behaviour from rawlog: 1.2.x: with Prefix ~/Mail A002 LIST "" "~/Mail/sent" * LIST (\NoInferiors \UnMarked) "/" "~/Mail/sent" A002 OK List completed. 2.0.x: with Prefix ~/Mail A0003 LIST "" ~/Mail/sent A0003 OK List completed.: Configured prefix for private spaces in roundcube mail is ~/Mail . Roundcube Webmail application checks for existence of the folder but dovecot doesn't return anything in 2.x.latest. Is this by design? Any ideas to fix it by configuration? (I tried prefix Mail/ in roundcube mail without success) Thunderbird works well. Thnx. Ciao, Gerhard

[Dovecot] Modifying LDAP search results for user_attrs
by Patrick Ben Koetter 04 Apr '12

04 Apr '12

I need to authenticate users via LDAP either by mailaddress or login name. In both cases the mailbox location is /src/mail/%d/%n. I can easily deduct that path from the mailaddress, but not so from the login name. Can I get the mail address as part of fetching user_attrs and modify it on the fly? Something along the lines of this: user_attrs = mail:/srv/mail/%d/%n=home,uidNumber=uid,gidNumber=gid Or would I be able to modify this with a post-login script? p@rick -- state of mind () Digitale Kommunikation http://www.state-of-mind.de Franziskanerstraße 15 Telefon +49 89 3090 4664 81669 München Telefax +49 89 3090 4666 Amtsgericht München Partnerschaftsregister PR 563
