Hi, I want to configure dovecot as gmail imap proxy. If any system in my network wants to connect to imap.gmail.com,993 it has to go through the dovecot proxy. Is it possible to setup such environment with dovecot? If yes, can you please help me to configure my dovecot server. Warm Regards Supratik

Hi all, is there some easy way to inform Dovecot about a new delivery, which has happened after postfix invoked maildrop, so the index files would be updated?

[Dovecot] Socket permission 432/384 and dovecot.conf
by Seba 19 Jan '10

19 Jan '10

Sorry for that question but: when you set in dovecot.conf this for example: socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } and you run "dovecot -n" you'll see client: path: /var/spool/postfix/private/auth mode: 432 I'm wondering about the mode "432" - how is this value calculated? Same for the auth/master socket socket - the value ist "384" and in dovecot.conf it's 0600. Thanks for any info. Seba

[Dovecot] Dovecot Proxy and environment variables
by BaQs 19 Jan '10

19 Jan '10

Dear list, First of all, I am French so excuse my bad english. I am currently using dovecot proxy feature, using sql backend. I "proxy" the imap/pop requests to another server, let's say server2. On server2, I use a script to keep up to date a "pop before smtp auth" database. I used mail_executable = /path/to/this/script.sh ... My problem is: the $IP environment variable on server2 is the proxy's IP. How could I give a variable from proxy to server2, or simply get the real client public IP ? Thanks a lot in advance for your answers Pierre. PS: let me also thank very much dovecot developers and community !

[Dovecot] No filelocking at "shared-mailboxes" dictionary?
by Peer Heinlein 18 Jan '10

18 Jan '10

Using imapsync I changed many ACLs on many accounts simultaneously in four concurrent IMAP-sessions. I started with an empty file "shared-mailboxes". But after the sync the file "shared-mailboxes" has been crashed. I found broken lines and I'm missing some entrys. Is it possible that there's no filelocking on that file? I used the ext3 filesystem. That's what shred-mailboxes looks like at the moment: shared/shared-box 1 shared/shared-boxes/user/user1.example.com/user2.example.com 1 .example.com/user5.example.com 1 hared/shared-boxes/user/user6.example.com/user4.example.c2442203233424^? 1 ser/user7.example.com/user2.example.com Peer dovecot -n: # 1.2.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.27.39-0.2-default x86_64 openSUSE 11.1 (x86_64) protocols: imap imaps managesieve ssl_cert_file: /etc/ssl/old.pem ssl_key_file: /etc/ssl/old.pem shutdown_clients: 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(managesieve): /usr/lib/dovecot/managesieve-login login_process_per_connection: no login_max_processes_count: 512 max_mail_processes: 1024 mail_max_userip_connections(default): 40 mail_max_userip_connections(imap): 40 mail_max_userip_connections(managesieve): 10 verbose_proctitle: yes mail_uid: vmail mail_gid: vmail mail_location: maildir:~/Maildir mail_executable(default): /usr/lib/dovecot/imap-usernamenmigration mail_executable(imap): /usr/lib/dovecot/imap-usernamenmigration mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugins(default): quota imap_quota acl imap_acl mail_plugins(imap): quota imap_quota acl imap_acl mail_plugins(managesieve): mail_plugin_dir(default): /usr/lib64/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib64/dovecot/modules/imap mail_plugin_dir(managesieve): /usr/lib64/dovecot/modules/managesieve namespace: type: private separator: / inbox: yes list: yes subscriptions: yes namespace: type: shared separator: / prefix: zz_SHARED_ACCOUNTS/%%u/ location: maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u list: yes lda: postmaster_address: postmaster(a)iea-dpc.org mail_plugins: quota acl sieve mail_plugin_dir: /usr/lib64/dovecot/modules/lda quota_full_tempfail: yes auth default: mechanisms: plain login digest-md5 cram-md5 verbose: yes debug: yes debug_passwords: yes passdb: driver: passwd-file args: /etc/dovecot/userdb userdb: driver: passwd-file args: /etc/dovecot/userdb userdb: driver: static args: uid=5001 gid=5001 socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 432 user: vmail group: vmail plugin: quota: maildir quota_rule: *:storage=102400 acl: vfile acl_shared_dict: file:/var/lib/dovecot/shared-mailboxes sieve: ~/.dovecot.sieve sieve_dir: ~/sieve -- Heinlein Professional Linux Support GmbH Linux: Akademie - Support - Hosting http://www.heinlein-support.de Tel: 030 / 40 50 51 - 0 Fax: 030 / 40 50 51 - 19 Zwangsangaben lt. §35a GmbHG: HRB 93818 B / Amtsgericht Berlin-Charlottenburg, Geschäftsführer: Peer Heinlein -- Sitz: Berlin

[Dovecot] Upgrade path questions
by Thomas M Goerger 18 Jan '10

18 Jan '10

Hi, We are currently running Dovecot v1.1.6 on our servers, and are contemplating an upgrade to 1.2, or 2.0 soon. We are wondering how many organizations are still running a 1.1 version of Dovecot, and if anyone has any thoughts on this transition. Have you upgraded from 1.1 to 1.2? What are your experiences with this? Have you upgraded from 1.1 to 2.0 directly? What are your experiences this way? We are also running an environment with both mbox and maildir formats. How many of you are running similarly, or are running solely maildir or mbox? We're just looking to gather information going forward, and anything you might be able to contribute would be very helpful. Thanks! ************************************************************************* * Tom Goerger - Email/Unix System Administrator * * * * University of Minnesota Email: tmg(a)umn.edu * * Operations, Infrastructure and Architecture Phone: 4-5804 * * Internet Services Office: 626J WBOB * * * *************************************************************************

[Dovecot] unlinking

Quick question. How important are these? Are the errors recoverable and not a big deal, or are they actually a problem? I see a few of these randomly over the course of the day.
