[Dovecot] 1.2.5: quota.c + quota_fs.c crashs dovecot
by Ralf Becker 16 Sep '09

16 Sep '09

Hi Timo, "quota.c" calls "root->backend.v.init_limits(root)", but "quota_fs.c" initializes this with NULL. On AIX e.g. this results in core dumping imap with SIGILL. I've attached a (quick and dirty) patch. Ralf -- ______________________________________________________________________ Dipl.-Inform.

[Dovecot] General question for Dovecot under OpenBSD
by jean-francois 15 Sep '09

15 Sep '09

Hello All, First of all thanks a lot for providing a quality software such as Dovecot. I am having troubles for setting up the config files of OpenBSD's binary package of Dovecot, flavor sieve/mysql. Do you know where some documentation could be found for setting up correctly the .conf (dovecot.conf & dovecot-sql.conf) since it does not even load ("Error in configuration file /etc/dovecot.conf line 871: Unknows setting: args"). I shall understand that the problem lies in dovecot-sql.conf, which is not a file I understand well and can configure correctly, as it seems. Some more docs/infos about this issue could be helpful. Thks, JF

[Dovecot] Thunderbird does not find the right folders :-(
by sterkel＠gmx.de 15 Sep '09

15 Sep '09

Moika, Overnight, I migrated my user-mails from uw-imap to dovecot-maildir. I used the uw2dovecot.pl script to convert all mails and changed exim, too. Receiving mails works fine allready, but nobody can access the usual subscribed folders with thunderbird. Via "subscriptions" I can find the converted folders in a folder called "_" (underline). People getting mad about me as the cannot find their stuff any more in the usual folders. What can I do that they have the converted stuff in the same folders as they had before?

Hi Timo, No, I mean, when I try to subscribe folders, I get offered a folder "_" with some subfolders. I do a screenshot, its maybe better to understand. The "real" folders in ~/Maildir look ok. > > -------- Original-Nachricht -------- > Datum: Tue, 15 Sep 2009 13:07:21 +0300 > Von: Timo Sirainen <tss(a)iki.fi> > An: sterkel(a)gmx.de > CC: dovecot(a)dovecot.org > Betreff: Re: [Dovecot] Thunderbird does not find the right folders :-( > > On Sep 15, 2009, at 11:10 AM, sterkel(a)gmx.de wrote: > > > Via "subscriptions" I can find the converted folders in a folder > > called "_" > > (underline). > > I don't really understand what this means.

[Dovecot] 1.2.4 Maildir Quota Issues
by Mario Antonio 15 Sep '09

15 Sep '09

Has anybody noticed this behavior when using maildir quota with Version 1.2.4: # 1.2.4: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-686-bigmem i686 Debian 5.0.3 xfs My default configurations quota configurations: plugin: quota: maildir:User quota quota_rule: *:storage=2G Customized Use Configurations at the Mysql level: user_query = SELECT 5000 AS uid,5000 AS gid,'/vmail/%d/%n' as home, \ concat('*:storage= ', virtual_users.quota_kb) AS quota_rule \ from virtual_users LEFT JOIN virtual_domains ON virtual_users.domain_id=virtual_domains.id \ where virtual_users.user='%n' and virtual_domains.name='%d' When I change quota at the SQL level (per user), that quota becomes active once Dovecot is restarted. Until then it keeps the previous quota assigned. I do not remember seeing this behavior in previous versions --quota was active after sql changes. M.A.

[Dovecot] fixing deleted-to-trash-plugin
by Lex Brugman 15 Sep '09

15 Sep '09

Hi, I'm currently trying to make the deleted-to-trash-plugin work with dovecot v1.2.4, without this plugin the trash mailbox is pretty useless with mail clients like Evolution and Outlook, I still can't believe this functionality isn't intergrated into dovecot since it doesn't even influence the operation of other mail clients that do support this option theirselfs (even when turned on, the plugin detects this and doesn't break the client's functionality). I have modified the plugin to run without errorsin 1.2.4, when using a mail client which doesn't support this feature in the client itself, (according to my debug and the mail-log plugin output) everything works, but the mails are deleted as expected but not visible in the Trash box, it looks like they where copied to /dev/null :P (even though the log output makes me think otherwise). Log output: Sep 09 20:21:09 IMAP(xxx(a)xxx.xxx): Info: opening Trash succeeded Sep 09 20:21:09 IMAP(xxx(a)xxx.xxx): Info: from INBOX to Trash, previous action from (null) Sep 09 20:21:09 IMAP(xxx(a)xxx.xxx): Info: copy: uid=11, dest=Trash, msgid=<7706BCE6-6882-473C-B7F3-62AE3F75F632(a)xxx.xxx>, size=1718 Sep 09 20:21:09 IMAP(xxx(a)xxx.xxx): Info: copying to Trash succeeded Sep 09 20:21:09 IMAP(xxx(a)xxx.xxx): Info: delete: uid=11, msgid=<7706BCE6-6882-473C-B7F3-62AE3F75F632(a)xxx.xxx> The clients I used to test: Evolution and Outlook (they both don't support this feature from the client) and the mail client on an iPhone (which does support this feature, the plugin detects that the client already copied the mail to the Trash box and skips it). I'm really stuck here :( no errors, the logs tell me everything went fine, but it didn't. The source is attached, any help is greatly appreciated! Gr, Lex Brugman

[Dovecot] Crash: imap process, Dovecot 1.2.4, related to ACLs (backtrace included)
by Andreas Ntaflos 14 Sep '09

14 Sep '09

Hi, I started experimenting with ACLs and found I could reliably and reproducibly crash the IMAP process when trying to create a subfolder of a folder that has has ACLs set. The folder is called "Sent" with an ACL of "owner lrwstipke". I wanted to be able to have certain folders the the user cannot delete but where subfolders can be created freely. Relevant information follows and I hope the backtrace is useful (lots of "value optimized out" entries). You can also find everything from below on <https://daff.pseudoterminal.org/misc/dovecot/>. Please tell me if I can provide more information. dovecot -n: =========== # 1.2.4: /usr/local/etc/dovecot.conf # OS: Linux 2.6.26-2-686 i686 Debian 5.0.2 log_timestamp: %Y-%m-%d %H:%M:%S protocols: managesieve imap imaps pop3 pop3s login_dir: /usr/local/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_executable(managesieve): /usr/local/libexec/dovecot/managesieve-login mail_access_groups: mail mail_privileged_group: mail mail_location: maildir:~/Maildir mail_drop_priv_before_exec: 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_executable(managesieve): /usr/local/libexec/dovecot/managesieve mail_plugins(default): autocreate acl mail_plugins(imap): autocreate acl mail_plugins(pop3): mail_plugins(managesieve): 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 mail_plugin_dir(managesieve): /usr/local/lib/dovecot/managesieve namespace: type: public separator: . prefix: Public. location: maildir:/var/mail/public:CONTROL=~/Maildir/control/public:INDEX=~/Maildir/index/public list: yes namespace: type: private separator: . prefix: Backup. location: maildir:~/Maildir-backup hidden: yes list: no namespace: type: private separator: . inbox: yes list: yes subscriptions: yes lda: log_path: info_log_path: auth_socket_path: /var/run/dovecot/auth-master postmaster_address: postmaster(a)mailtest0.rise-s.com mail_plugins: sieve acl auth default: mechanisms: plain login passdb: driver: pam passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: passwd userdb: driver: static args: uid=vmail gid=vmail home=/var/vmail/%Ld/%Ln allow_all_users=yes socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail plugin: sieve: ~/.dovecot.sieve sieve_dir: ~/sieve sieve_global_path: /etc/dovecot/sieve/default.sieve sieve_global_dir: /etc/dovecot/sieve/global/ sieve_before: /etc/dovecot/sieve/before/ autocreate: Trash autocreate2: Drafts autocreate3: Sent autocreate4: INBOX.Spam autosubscribe: Trash autosubscribe2: Drafts autosubscribe3: Sent autosubscribe4: INBOX.Spam acl: vfile:/etc/dovecot/acl Log entry: ========== Aug 28 01:08:01 mailtest0 dovecot: IMAP(andreas.ntaflos(a)example1.rise-s.com): Panic: file acl-backend-vfile.c: line 1124 (acl_backend_vfile_object_update): assertion failed: (!update->rights.global) Aug 28 01:08:01 mailtest0 dovecot: IMAP(andreas.ntaflos(a)example1.rise-s.com): Raw backtrace: imap [0x80f1ec1] -> imap [0x80f1f42] -> imap [0x80f18c9] -> /usr/local/lib/dovecot/imap/lib01_acl_plugin.so [0xb7dddcf6] -> /usr/local/lib/dovecot/imap/lib01_acl_plugin.so(acl_object_update+0x18) [0xb7ddb1a8] -> /usr/local/lib/dovecot/imap/lib01_acl_plugin.so [0xb7de2ac7] -

[Dovecot] Dovecot+PAM advice please?
by S. A. Woltering 14 Sep '09

14 Sep '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, sorry to bother you with this. I'm trying to set up an experimental system (which may become production if it ever gets off the ground) and it's not working. The short version: I'm trying to get Dovecot 1.2.4 to authenticate against a customised PAM module. In short, we're using a specialised OTP radius backend. One of my colleagues has coded up a PAM module for this backend. The IMAP service is on HP-UX11.23, IA64. The module is compiles into /usr/lib/security/hpux32 and is called "pam_cached_radius.so.0.0". The entry in /etc/pam.conf is: cached-radius auth required pam_cached_radius.so.0.0 The PAM module compiles OK, and my colleague's test suite (run, both as root and as our local "dovecot" user) works fine. When I use the following options in dovecot.conf: auth default { user = root mechanisms = plain passdb pam { args = cached-radius } userdb passwd { } } it fails leaving only the log entry below in syslog. Sep 14 09:15:15 elrond syslog: load_modules: can not open module /usr/lib/security/hpux32/pam_cached_radius.so.0.0 Sep 14 09:15:22 elrond syslog: load_modules: can not open module /usr/lib/security/hpux32/pam_cached_radius.so.0.0 (Always 2 entries). I appreciate that this probably isn't a dovecot issue per se, but it is suspicious that our test suite works and divecot can't access the module. I'd be most grateful if anyone could offer some possible avenues of investigation.

[Dovecot] Problems getting Dovecot to work.
by Mark Gillespie 14 Sep '09

14 Sep '09

Hi, having a nightmare trying to get dovecot working on my SheevaPlug (flash based ARM embedded device). I need to use virtual users, and I need to store all the mail on an external USB HDD (not in home directories which live in the limited flash space). However I can't even log in via telnet. I've followed the Wiki troubleshooting tips, and still no further forward. logging via telnet, I get: "user sheeva BAD Error in IMAP command received by server." the logs show: ubuntu dovecot: User sheeva is missing UID (see mail_uid setting) What do I need to do? I know basic Linux stuff, but I wouldn't call myself an expert, so please no tech talks!!! -- Using Opera's revolutionary e-mail client: http://www.opera.com/mail/
