[Dovecot] Aborted: Worker is buggy
by David Jonas 25 Aug '09

25 Aug '09

I upgraded from 1.1 to 1.2 a couple months ago and now we are seeing this: Aug 20 05:34:38 kelly dovecot: auth(default): auth workers: Auth request was queued for 7 seconds, 10 left in queue ... Aug 20 05:34:38 kelly dovecot: auth(default): BUG: Worker sent reply with id 53, expected 54 Aug 20 05:34:38 kelly dovecot: auth(default): worker-server(xxx(a)example.com,dd.dd.dd.dd): Aborted: Worker is buggy Aug 20 05:34:38 kelly dovecot: auth(default): passdb(xxx(a)example.com,dd.dd.dd.dd): Fallbacking to expired data from cache When I attempt to restart dovecot there is one dovecot-auth process that won't die and keeps the server from starting. A simple 'killall dovecot-auth' takes care of it and the server is able to start. I'm not using anything exotic, dovecot config below. The most curious fact is that we have identical servers running the same version of dovecot (1.2.3, happened under 1.2.1 as well) talking to the same MySQL database and both develop the problem at the same time. The database is under considerable stress at the time this occurs as the policyd tables are being cleaned. But this happens twice per hour and only sometimes does dovecot have trouble. I'm working to move the policyd database elsewhere, but of course this shouldn't happen in any case. Any help would be much appreciated. Thanks!

[Dovecot] Per user namespace
by Ashley M. Kirchner 25 Aug '09

25 Aug '09

I'm in the process of upgrading an old server which is running uw-imap to a new one running Dovecot. With the old machine, unfortunately, my users had the opportunity to store their e-mails in various locations. For example, some have their mail boxes stored in ~/mail/[various mbox files], others ALSO have a ~/mail/clients/[various mbox files] and yet others simply stored them in their ~/ path (thanks to the old IMAP). Is there a way to create per-user namespaces? I don't want to create a "mail/", "mail/clients/", etc., etc. global name space that will end up showing up on everyone's mail client, nor do I want to individually change each user's setup (and rewrite their .subscriptions file). Any solutions here, or am I SOL? AMK4 -- W | It's not a bug - it's an undocumented feature. +-------------------------------------------------------------------- Ashley M.

[Dovecot] quota bug
by Amr Shahin 24 Aug '09

24 Aug '09

Hello i use dovecot for our mail server, it's installed on about 8 servers and it's doing really good, thanks for the great effort :-) however, i have been facing a quota problem recently, dovecot says that some users are using for example (700MB) while they are actually using (10MB), i solve this by removing *maildirsize *which solves it, is there any fix for this bug ? thanks and regards Amr Shahin

Re: [Dovecot] Dovecot and LDAP-Quotas
by south africa 24 Aug '09

Hi Timo, thank you for your reply. I take the configuration from http://www.linuxmail.info/postfix-dovecot-ldap-centos-5/ especially the dovecot-configuration for passdb and userdb. As you mentioned in your reply I added the userdb ldap with a symbolic link on the original dovecot-ldap.conf: userdb: driver: ldap args: /etc/dovecot-ldap-userdb.conf but with no success. Any hints? I have another question: Does Dovecot expect a special "field type" for the ldap quota field (for ex. integer)?

[Dovecot] Dovecot LDA
by Wouter van der Schagt 24 Aug '09

24 Aug '09

Good morning, Still not having luck to get the LDA to work, using Qmail + Vpopmail and read the wiki. I'm using: auth default { mechanisms = plain passdb vpopmail { } userdb vpopmail { } user = vpopmail count = 1 ssl_require_client_cert = no } Which work well for authenticating users, however when using the following in a .qmail file: |/var/qmail/bin/preline -f /usr/local/libexec/dovecot/deliver -d $EXT@$USER I get the following error message: Error:_userdb_lookup:_connect(/usr/local/var/run/dovecot//auth-master)_failed:_No_such_file_or_directory/ Eventhough it should have been created (I think) in the protocol lda section of the config file. I specifieD: auth_socket_path = /var/run/dovecot/auth-master However I thought since using vpopmail I don't need to use the auth-master ? or am I missing something? Sincerely, - Wouter van der Schagt

[Dovecot] Failover authentication Ldap
by Michel Bulgado 24 Aug '09

24 Aug '09

Hi List I use dovecot with LDA deliver, have quotas for my users use postfix as MTA server. as it could limit or refuse delivery of mail once the user has exceeded the limit of the quota? As in my configuration could define multiple LDAP servers? I have two servers with Active Directory, a PDC and a BDC, but I would specify both in the same configuration. for when the ldap server 1 has problems, authenticating against Ldap 2 . Thanks Michel

[Dovecot] Problems with dovecot/sendmail combi.
by Roger Berger 24 Aug '09

24 Aug '09

Hi, I am really stuck here. I am trying to setup imap for an external mail server. I have a freebsd server running sendmail / dovecot. I am transfering the existing mail from an exchange 2003 server to the mailserver using imapsync. This works fine, but gives errors when it tries to make a submap, also thunderbird gives an error "Mailbox doesn't allow inferior mailboxes" when I try to make a submap. I found out that it has something to do with the mbox not able to have submaps and there should be a workaround using namespaces. I tried several setups but keep getting errors. Does anybody know how to configure namespaces to allow submaps? dovecot -n # 1.2.3: /usr/local/etc/dovecot.conf # OS: FreeBSD 6.4-STABLE i386 log_path: /var/log/dovecot.log protocols: imap imaps pop3 pop3s disable_plaintext_auth: no verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login login_process_per_connection: no login_processes_count: 4 verbose_proctitle: yes first_valid_gid: 0 mail_access_groups: mail mail_location: mbox:~/mail:INBOX=/var/mail/%u mail_debug: yes mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 imap_client_workarounds(default): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(pop3): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh namespace: type: private separator: / prefix: #mbox/ location: mbox:~/mail:INBOX=/var/mail/%u inbox: yes list: yes subscriptions: yes namespace: type: private separator: / location: maildir:~/mail list: yes subscriptions: yes lda: postmaster_address: postmaster(a)example.com sendmail_path: /usr/sbin/sendmail auth default: verbose: yes debug: yes debug_passwords: yes passdb: driver: pam userdb: driver: passwd mbox is in /var/mail/%u and home dir is in /home/mailusers/%u

[Dovecot] sieve vacation response
by Jure Pečar 24 Aug '09

24 Aug '09

Hello, we're implementing a dovecot 1.2.1 with sieve 0.1.7 and managesieve 0.11.7. We're having problems with creating sieve scripts so that vacation works. Our script looks like this: require ["fileinto", "vacation"]; if address :matches ["To", "Cc"] "*someone(a)example.com*" { if not header :matches "X-Spam-Status" "Yes*" { vacation :days 1 :subject "test" "autoresponder test."; keep; } } And when sent and delivered to someone(a)example.com, we get this in the log: dovecot: deliver(username): sieve: msgid=<...>: discarding vacation response for message implicitly delivered to <username(a)fqdn.hostname.com> Our final recipients are in the form of username(a)fqdn.hostname.com; it looks like this is being matched in sieve as address. But we want to match against original recipient address, not address after alias expansion. Any ideas? -- Jure Pečar http://jure.pecar.org http://f5j.eu

[Dovecot] High load with Thunderbird
by Emmanuel Seyman 24 Aug '09

24 Aug '09

Hello, all. I'm using Dovecot 1.0.15 on our internal mail server and I'm seeing a high load from one of our users. This user uses Thunderbird (with the IMAP protocol) and the load average of the server goes through the roof every once in a while. I'ld like to understand why we're seeing this and whether the blame should be put on Thunderbird or on Dovecot. Has anyone ever seen this before? Emmanuel
