[Dovecot] Public Folder for mailinglist with deliver
by Sebastian Heil 21 Mar '10

21 Mar '10

Hello Everybody, I'm looking for a nice way to implement the following: We are running a mail server for system users who are having their own mailbox. Now there's the idea to subscribe for a few mailinglists which are then available for the user per shared/public folder. So they can simply subscribe and unsubscribe with their MUA. For every mailinglist subscription there should exist an own email account with own mail directory. The namespaces are already working (in a test environment). But I haven't found any implementation to realize this nicely with deliver. The possiblities I'm thinking about are: -create a somewhere in userdb a passwd entry for each mailinglist email address with the corresponding directory -create a static userdb entry, but then deliver cannot check if an email address/mailbox exists. I think both ideas aren't a good implementation. So I'm asking you for help. Has someone a similar setup or a little idea how to make this work with deliver. Thanks in advance Sebastian

Since I haven't had the opportunity to update my hg handling setup yet, I just created a symlink; for those looking for a quick workaround until a beta4 or a rc1 gets issued, and assuming --sysconfdir=/usr/local/etc: /usr/local/etc/dovecot/dovecot.conf -> ../dovecot.conf No great info of course. ;-) Axel

[Dovecot] Sendmail + deliver; silent errors.
by Daryl Tester 20 Mar '10

20 Mar '10

Hi all. I've got a bit of a peculiar issue here. I'm running dovecot 1.2.9 on an Ubuntu 9.10 box using Sendmail 8.14.3. I've set up Sendmail similar to <http://wiki.dovecot.org/LDA/Sendmail> except that *) dovecot's deliver is configured as my default local mailer, so some of the flags for the Mailer definition had to be adjusted accordingly. *) The setuid users listed in the wiki kept result in setgid() failures from deliver, so I've changed it to root:mail (mail being sendmail's MDA group), with permissions as u+s,g+rx,o-rwx When sendmail attempts delivery, I'm getting "deferred: deliver failed with EX_TEMP", but nothing recorded in the log files. I've embarrassingly widened the permissions of /var/log/dovecot and the files contained within to read/write everyone, just to ensure that whomever it's running as has access, but the log files aren't updated. The peculiar thing kicks in when I attempt to debug this. So far I have (amongst other things): *) Run deliver from the command line logged in as "mail". *) written a shell wrapper script to be able to confirm things like the user ID that was invoking deliver. *) both in the shell script, and as an mailer definition in sendmail, strace'd (using a setuid root binary) deliver to capture what it was doing. Whenever I do any of the above, deliver works perfectly, and appears to log correctly. It only appears to bork when no-one is watching it, which is quite frustrating when trying to fix it. Help? Configuration of dovecot follows: # 1.2.9: /etc/opt/dovecot-1.2.9/dovecot.conf # OS: Linux 2.6.31-14-server x86_64 Ubuntu 9.10 ext3 base_dir: /var/run/dovecot-1.2.9/ log_path: /var/log/dovecot/dovecot.log info_log_path: /var/log/dovecot/dovecot-info.log protocols: pop3 imap imaps ssl: no disable_plaintext_auth: no login_dir: /var/run/dovecot-1.2.9//login login_executable(default): /opt/dovecot-1.2.9/libexec/dovecot/imap-login login_executable(imap): /opt/dovecot-1.2.9/libexec/dovecot/imap-login login_executable(pop3): /opt/dovecot-1.2.9/libexec/dovecot/pop3-login mail_uid: vmail mail_gid: vmail mail_location: maildir:/vmail/spool/%u:LAYOUT=fs mail_executable(default): /opt/dovecot-1.2.9/libexec/dovecot/imap mail_executable(imap): /opt/dovecot-1.2.9/libexec/dovecot/imap mail_executable(pop3): /opt/dovecot-1.2.9/libexec/dovecot/pop3 mail_plugin_dir(default): /opt/dovecot-1.2.9/lib/dovecot/imap mail_plugin_dir(imap): /opt/dovecot-1.2.9/lib/dovecot/imap mail_plugin_dir(pop3): /opt/dovecot-1.2.9/lib/dovecot/pop3 lda: postmaster_address: postmaster(a)handcraftedcomputers.com.au auth_socket_path: /var/run/dovecot-1.2.9/auth-master auth default: verbose: yes passdb: driver: passwd-file args: /vmail/auth/passwd userdb: driver: static args: uid=vmail gid=vmail socket: type: listen master: path: /var/run/dovecot-1.2.9/auth-master mode: 384 user: vmail group: vmail -- Regards, Daryl Tester Member of the Amalgamated Australian Association Against Apostrophe Abuse.

[Dovecot] Dovecot v2.0.beta3 quota using userdb
by e-frog 20 Mar '10

20 Mar '10

Hello Timo, I'm playing around with the new Dovecot v2.0.beta3 and don't seem to be able to get quotas working from userdb. I didn't change the SQL query which was working for 1.2.10. Feb 20 19:34:06 ubuntu-test dovecot: auth: sql(test,192.168.156.99): SELECT home, mail, uid, gid, concat('*:storage=', quota_limit, 'MB') AS quota_rule FROM users WHERE username = 'test' ...

Note there is no "Quota rule". However it seems to work by adding "quota_rule = *:storage=1024MB" directly to plugin.conf: ... Feb 20 19:39:15 ubuntu-test dovecot: imap(test): Quota root: name=user backend=dict args=:proxy::dictionary Feb 20 19:39:15 ubuntu-test dovecot: imap(test): Quota rule: root=user mailbox=* bytes=1073741824 messages=0 Feb 20 19:39:15 ubuntu-test dovecot: imap(test): dict quota: user=test, uri=proxy::dictionary, noenforcing=0 ...

[Dovecot] INBOX of a shared namespace appears to be always subscribed
by Holger Richter 20 Mar '10

20 Mar '10

In dovecot 1.2.10 I run into the following problem: Our users are entitled to share their personal mailboxes. This works. But if user A shares any of its mailboxes with user B, then dovecot always reports the INBOX of user A as subscribed by user B. No matter whether user B really subscribed the INBOX of A, or whether user A permitted user B the access to its INBOX. The problem is caused by the repeated call of LSUB. Starting with the second call LSUB always shows INBOX as subscribed. To reproduce: -> telnet imap.xx.yy 143 1 LOGIN user password 2 LSUB "" shared/* => shows shared/UserB/folderXX 3 LSUB "" shared/* => shows shared/UserB/INBOX shared/UserB/folderXX 4 LSUB "" shared/* => shows shared/UserB/INBOX shared/UserB/folderXX Regards, Holger

[Dovecot] problem with master db and dovecot-2.0.beta3
by Oliver Eales 19 Mar '10

19 Mar '10

Hello, i am currenty testing dovecot 2.0.beta3 and ran into a problem with the master-db setting. For our webmail access we are sucessfully using the following settings with dovecot-1.2.10 auth_master_user_separator =* auth default { mechanisms = plain passdb passwd-file { args = /etc/dovecot/passwd.masterusers master = yes pass = yes } passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } } when "converting" the settings to version 2.0 i tried the following: auth_mechanisms = plain auth_master_user_separator = * passdb { driver = passwd-file args = /etc/dovecot/passwd.masterusers master = yes pass = yes } passdb { driver = ldap args = /etc/dovecot/dovecot-ldap.conf } But when i try to login, the auth process gets stalled with the following log entry: auth: Fatal: Master passdb can't have pass=yes if there are no passdbs master: Error: service(auth): command startup failed, throttling Am i doing something wrong or is it problem with the 2.0-beta ?

[Dovecot] Triggering mailbox fetch
by Brian Candler 19 Mar '10

19 Mar '10

Greetings, I would like to migrate mailboxes into a Dovecot system by using an IMAP transfer from the old system - and I'd like this to take place automatically at the time the user first logs into the new system. I have a script which will perform an IMAP fetch and dump it into the local maildir. In courier-imap I could create a '.loginexec' file which is executed when the user logs in, and gets deleted if it completes successfully. I'm trying to find something similar for Dovecot. * fetchmail-wakeup is the right kind of idea, but I need it to stop running once mail has been transferred successfully once. It also needs different parameters for each user (e.g. user/pass used to login to the remote IMAP server) * The convert_mail plugin only works with local mail spools, as far as I can tell. I'm not sure how it determines whether conversion has already taken place (whether the target maildir already exists?) * autocreate only creates empty mailboxes Any of these might be a starting point for developing my own plugin, but does anyone here know of an existing one which would do the job? Thanks, Brian.

[Dovecot] Problem with quota recreation
by Uroš Gruber 19 Mar '10

19 Mar '10

Hi, I'm migrating from cyrus to dovecot 1.2.10 with cyrus2dovecot. I've setup quota with mysql dict and while testing delivery quota is working fine. The only problem is when i migrate mailbox from cyrus to dovecot and when bytes and messages is set to 0. I tried with x GETQUOTAROOT Inbox but the quota usage is not recalculated and when a new message is delivered quota is calculated only on the new message. Any help would be greatly appreciated. Best regards Uros

[Dovecot] ACL + shared-imap + nested AD groups
by Martin Ott 19 Mar '10

19 Mar '10

Hi, I'm looking for a solution to use nested AD groups for authorization in shared-imap folders(namespace public). As a simple hack to determine the (primary) groups of a user we use the following setup with a post-login script: in dovecot.conf ... protocol imap { mail_executable = /etc/dovecot/ldap_groups.sh ... ldap_groups.sh ACL_GROUPS=`ldapsearch -h ldapserver -p 3268 -s sub -D "cn=ldap mail, ou=user, ou=global, ou=xxx, dc=xxx, dc=local" -b "ou=xxx, dc=xxx, dc=local" "(&(sAMAccountName=$USER))" -LLL memberOf -w password | grep "memberOf: CN=" | sed 's/memberOf: CN=//' | sed 's/,OU=.*//' | tr "\n" "," | sed 's/, $//'` export ACL_GROUPS exec /usr/libexec/dovecot/imap $* Does anyone know, how to simply get the groups of groups with such a post-login script? Thanks, Martin
