[Dovecot] Default mbox file ownership and permissions with static userdb
by Christian Kreibich 18 Jan '09

18 Jan '09

Hi there! I'm using Dovecot 1.1.7 in a simple setup with a static userdb: userdb: driver: static args: uid=50018 gid=50019 home=/home/dovemail When my users create folders via IMAP, the ownership of the mbox file is user dovemail, group dovemail, and permissions are 600. I'd like this to change to user dovemail, group doveusers, permissions 660, but I can't figure out a way to do it. Can anyone help? Thanks in advance. -- Cheers, Christian

[Dovecot] Possible Bug segnalation
by Claudio Prono 18 Jan '09

Hi to all, Today i have manually copied at least 250 mail from a mailbox to another and i have encountered some problems with dovecot. When finished to download all the messages, via pop3, at the next check mail dovecot give me that error: dovecot: Jan 15 10:59:55 Info: POP3(michele(a)domain.net): Mailbox init failed top=0/0, retr=0/0, del=0/29, size=932800 Then, the messages from the pop server was deleted, to the client an error was given but no mail downloaded. I have resolved that deleting all the dovecot files into the mailbox, so: dovecot-uidlist dovecot.index dovecot.index.cache dovecot.index.log Then, all restarted to works normally, but...the most bad thing is... the lost mails! I use OpenSuSE 11 with dovecot11-1.1.3-5.1 with postfix and virtual users on mysql. Here is my dovecot -n: # 1.1.3: /etc/dovecot/dovecot.conf log_path: /var/log/dovecot-err.log info_log_path: /var/log/dovecot-inf.log protocols: imap imaps pop3 pop3s disable_plaintext_auth: no 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 first_valid_uid: 51 last_valid_uid: 51 first_valid_gid: 51 last_valid_gid: 51 mail_location: maildir:/var/mail/virtual/%d/%u mail_debug: yes mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota 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 imap_client_workarounds(default): outlook-idle imap_client_workarounds(imap): outlook-idle imap_client_workarounds(pop3): pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): %Mf auth default: passdb: driver: sql args: /etc/dovecot/dovecot-mysql.conf userdb: driver: passwd userdb: driver: sql args: /etc/dovecot/dovecot-mysql.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 plugin: quota: maildir quota: maildir:user quota quota_warning: storage=80%% /usr/bin/quota_warning.sh 80 quota_warning2: storage=90%% /usr/bin/quota_warning.sh 90 quota_warning3: storage=99%% /usr/bin/quota_warning.sh 90 Anyone have some similar experience to mine?

[Dovecot] Trouble with %d in args of passwd-file
by Nathan Hüsken 18 Jan '09

18 Jan '09

Hello, I am trying to configure my dovecot folowing this guide: http://www.w3style.co.uk/virtual-domains-with-exim-and-dovecot I append the output of dovecot -n below. I created /etc/vmail/my-domain.de/user containing: test-user:{PLAIN}test:1002:100::/home/test-user:: No I try to login: telnet 127.0.0.1 143 Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'. * OK This is Dovecot, and it is ready. a01 LOGIN test-user(a)my-domain.de test a01 NO Authentication failed. It does not work! But when I change the "%d" to my-domain.de, and login without the domain, it works! What am I doing wrong? Thanks!

[Dovecot] 1.1.9 release candidate
by Timo Sirainen 18 Jan '09

18 Jan '09

http://dovecot.org/tmp/dovecot-1.1.9.rc.tar.gz There are a couple of a bit larger changes, so would be nice if a few people tested this on different setups before I released the final v1.1.9. Changes since v1.1.8: + deliver: Added rejection_subject setting, which is used for rejected mails. + pop3: Prevent clients from looping forever trying to fetch an expunged message. + If login process crashes, log the IP address that (maybe) caused it. + If core dump limit is 0, add "core dumps disabled" to startup log line. - mbox: Fixed assert-crash with pop3_lock_session=yes - dbox: Fixes to handling maildir-converted files. - Auth cache wasn't working correctly for all fields (e.g. allow_nets) with blocking passdbs (e.g. mysql). - pgsql: Handle reconnecting to server without failing auth lookups. - Berkeley DB memory/resource leak fixes. - maildir: Fixes to handling over 26 keywords.

Ah, ok. I think blackberry is an exception here. But actually you can disable IDLE by changing imap_capability setting manually. Set it to the default CAPABILITY reply you get from Dovecot, just remove IDLE.

Have looked through all of the config options in the wiki and don't see a reference to turning off IDLE similar to courier's capability. Is it possible? Thanks for any pointers. Using version 1.1.6

[Dovecot] Patch to deliver
by Allan Cassaro 16 Jan '09

16 Jan '09

Hi Timo! I wrote a little patch to add the capability of the deliver to customize the "subject" of the rejection messages. Now is possibly to translate the body and subject! In dovecot.conf: rejection_reason_subject = Automatically rejected mail to %t rejection_reason = Your message to <%t> was automatically rejected:%n%r Please, review the patch! :D
