[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' ... Feb 20 19:34:06 ubuntu-test dovecot: imap(test): Quota root: name=user backend=dict args=:proxy::dictionary Feb 20 19:34:06 ubuntu-test dovecot: imap(test): dict quota: user=test, uri=proxy::dictionary, noenforcing=0 ... 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 ... Has there anything changed in dovecot 2.0 in this perspective?

[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 ? Regards, Oliver Eales

[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

[Dovecot] 2.0beta3 10876:370ee9717a6c broke listen on literal IPv6 address
by Bernhard Schmidt 19 Mar '10

19 Mar '10

Hi, apparently the following change in dovecot hg * New revision (10876:370ee9717a6c) in dovecot Mercurial repository: - config: Forgot to add header file. broke listen = 83.170.6.69, 2001:1b10:1000::110:1:1 mail.svr02.mucip.net:~# dovecot -F -c /etc/dovecot/dovecot.conf doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:29: listen=..:port has been replaced by service { inet_listener { port } } doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf: duplicate listener: 1: Is this even possible? That doesn't make sense to me, but Stephan's +29 works fine for me, +30 (with just that change according to changelog) doesn't. Bernhard

[Dovecot] GlusterFs - Any new progress reports?
by Ed W 18 Mar '10

18 Mar '10

GlusterFs always strikes me as being "the solution" (one day...). It's had a lot of growing pains, but there have been a few on the list had success using it already. Given some time has gone by since I last asked - has anyone got any more recent experience with it and how has it worked out with particular emphasis on Dovecot maildir storage? How has version 3 worked out for you? Anyone had success using some other clustered/HA filestore with dovecot who can share their experience? (OCFS/GFS over DRBD, etc?) My interest is more in bootstrapping a more highly available system from lower quality (commodity) components than very high end use Thanks Ed W

Re: [Dovecot] sieve vacation
by Martin F. Foster 18 Mar '10

18 Mar '10

Following from Steffen Kaiser's response, RFC5230 explains the conditions necessary for the Sieve Vacation extension to trigger a response. This says: "Vacation" MUST NOT respond to a message unless the recipient user's email address is in a "To", "Cc", "Bcc", "Resent-To", "Resent-Cc", or "Resent-Bcc" line of the original message. So your scenario 4 happens when the sender is only in the envelope, and not in the headers. For example: this transaction will get a response because the mailbox address is in the To: header ehlo there.com mail from: <dude(a)there.com> rcpt to: <user(a)domain.tld> << envelope recipient, mailsystem routes with this information data To: "Some User" <user(a)domain.tld> << header recipient must be correlated for Sieve Vacation to send a response From: "Dude" <dude(a)there.com> Subject: message Hi there . This transaction will not get a response, and will trigger the "discarding vacation response for message implicitly delivered to <user(a)domain.tld> " log: ehlo there.com mail from: <dude(a)there.com> rcpt to: <user(a)domain.tld> data Subject: message Hi there .

[Dovecot] Dovecot 2.0 b13e01d82083
by Renaud Allard 18 Mar '10

18 Mar '10

Hello, I was trying to compile Dovecot 2.0 b13e01d82083, and I found this when doing make: Making all in lib test -f UnicodeData.txt || wget http://www.unicode.org/Public/UNIDATA/UnicodeData.txt /bin/sh: wget: not found I think it's probably not the best idea to assume everyone has wget installed. Perhaps it is installed by default on linux, but probably not on all other platforms. Why not just include the UnicodeData.txt file? Best Regards
