[Dovecot] Segfault in dovecot 1.2rc2 with quota + public namespace enabled
by Markus Werner 07 Apr '09

07 Apr '09

Hi, I have configured a public namespace ("#Shared"). Since dovecot 1.2rc2 (1.1.11 worked fine) I get a segfault, if I try to access a folder under this namespace when quota plugin is enabled. When the quota plugin is disabled, accessing those folders works. $ dovecot -n # 1.2.rc2: /opt/dovecot/etc/dovecot.conf # OS: Linux 2.6.26-1-686 i686 Debian 5.0 base_dir: /var/run/dovecot protocols: imap pop3 listen: 127.0.0.1,192.168.128.151 ssl_listen: 192.168.128.151 ssl_ca_file: /opt/dovecot/etc/certs/cacert.pem ssl_cert_file: /opt/dovecot/etc/certs/asterixCert.pem ssl_key_file: /opt/dovecot/etc/certs/asterixKey.pem ssl_parameters_regenerate: 0 ssl_cipher_list: ALL:!LOW:!SSLv2 disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /opt/dovecot/libexec/dovecot/imap-login login_executable(imap): /opt/dovecot/libexec/dovecot/imap-login login_executable(pop3): /opt/dovecot/libexec/dovecot/pop3-login login_user: dovecotl login_process_per_connection: no login_processes_count: 1 login_max_processes_count: 3 max_mail_processes: 100 mail_max_userip_connections: 8 first_valid_uid: 2000 last_valid_uid: 2000 first_valid_gid: 2000 last_valid_gid: 2000 mail_access_groups: dovecot mail_uid: 2000 mail_gid: 2000 mail_location: maildir:~/Maildir mail_debug(default): yes mail_debug(imap): yes mail_debug(pop3): no mail_executable(default): /opt/dovecot/libexec/dovecot/imap mail_executable(imap): /opt/dovecot/libexec/dovecot/imap mail_executable(pop3): /opt/dovecot/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota acl imap_acl fts fts_squat mail_plugins(imap): quota imap_quota acl imap_acl fts fts_squat mail_plugins(pop3): mail_plugin_dir(default): /opt/dovecot/lib/dovecot/imap mail_plugin_dir(imap): /opt/dovecot/lib/dovecot/imap mail_plugin_dir(pop3): /opt/dovecot/lib/dovecot/pop3 pop3_no_flag_updates(default): no pop3_no_flag_updates(imap): no pop3_no_flag_updates(pop3): yes namespace: type: private separator: / prefix: INBOX/ inbox: yes list: yes subscriptions: yes namespace: type: public separator: / prefix: #Shared/ location: maildir:/var/spool/dovecot/sharedfolders:INDEX=~/Maildir/index/public:CONTROL=~/Maildir/control/public list: yes subscriptions: yes namespace: type: shared separator: / prefix: #User/%%u/ location: maildir:%%h/Maildir:INDEX=~/Maildir/index/shared/%%u list: yes auth default: mechanisms: plain login user: dovecota worker_max_count: 3 passdb: driver: passwd-file args: /opt/dovecot/etc/passwd userdb: driver: passwd-file args: /opt/dovecot/etc/passwd socket: type: listen client: path: /var/run/dovecot/auth-client mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 432 user: dovecota group: dovecot plugin: sieve: ~/.dovecot/.dovecot.sieve acl: vfile:/opt/dovecot/etc/dovecot-acls acl_shared_dict: file:/var/lib/dovecot/shared-mailboxes.db acl_anyone: allow quota: dict:user::file:%h/Maildir/dovecot-quota quota_rule: *:storage=10G:messages=500000 fts: squat fts_squat: partial=4 full=10 $ gdb /opt/dovecot/libexec/dovecot/imap /var/spool/dovecot/users/markus/core GNU gdb 6.8-debian Copyright (C) 2008 Free Software Foundation, Inc.

[Dovecot] v1.3 plugin locations
by Timo Sirainen 07 Apr '09

07 Apr '09

It's getting more and more annoying to have separate plugin directories for lda, pop3 and imap. Currently all the plugins are installed into $lib/dovecot/ and then symlinked to the lda, pop3, imap directories. The original reason was that v0.99 just loaded everything in those directories since there was no mail_plugins setting. But then there are things like expire-tool and convert-tool (and the upcoming doveadm) that don't load plugins at all, even though they probably should. Adding just more directories to them seems to be pointless. Also SQL plugins are shared by dovecot-auth and dict and those would need symlinking.. And in future you might want to load SQL plugins to e.g. imap process. So, I was planning on just putting everything into $lib/dovecot/. expire-tool etc. would use mail_plugins setting that wasn't inside protocol {}. So for example: mail_plugins = quota protocol lda { mail_plugins = quota sieve } protocol imap { mail_plugins = quota imap_quota } protocol pop3 { # defaults to mail_plugins=quota above, no need to set it explicitly } That leaves auth and dict.. I was considering adding new auth_plugins and dict_plugins settings, but that might make it more difficult to start using distro-compiled Dovecot where sql, ldap, etc. are in plugins. So perhaps the auth/ and dict/ directories can stay and contain symlinks. But the $lib/dovecot/sql/ directory could go away and the sql plugins be stored just in $lib/dovecot/ among everything else. Any thoughts?

[Dovecot] Compile and configure Solr plugin
by Rui Carneiro 07 Apr '09

07 Apr '09

Hi all, I'm having some kind of troubles on Solr's integration. I configured Dovecot with the Solr argument (--with-solr) and everything proceeded just fine. But, when I started Dovecot I got this error: Plugin fts_solr not found from directory /usr/lib64/dovecot/modules/imap Error: imap dump-capability process returned 89 Fatal: Invalid configuration in /etc/dovecot/dovecot.conf In fact, there is no Solr plugin in that directory. So I tried to make a symbolic link from where the compiled Solr plugin was to this directory: ln -s /usr/local/lib/dovecot/lib21_fts_solr_plugin.so And now I have the following error: dlopen(/usr/lib64/dovecot/modules/imap/lib21_fts_solr_plugin.so) failed: /usr/lib64/dovecot/modules/imap/lib21_fts_solr_plugin.so: undefined symbol: mailbox_get_virtual_box_patterns Couldn't load required plugins Error: imap dump-capability process returned 89 Fatal: Invalid configuration in /etc/dovecot/dovecot.conf I'm missing some steps in this installation for sure, do anyone have any clue? Thanks, Rui Carneiro

[Dovecot] Modified websieve for use with dovecot
by Wolfgang.Friebel＠desy.de 07 Apr '09

07 Apr '09

In order to let users construct a sieve filter using a GUI I have taken websieve.pl from Alain Turbide (for use with Cyrus) and modified it to work with dovecot. In order to get it working quickly I have removed all the code I did not need (e.g. ldap support, password authentication) and coded Kerberos5 auth (via GSSAPI or SASL) in. I understand that this makes the work mostly useless to others. As however the dovecot adaptations were done by removing internally used perl packages by ones on CPAN such as Mail::IMAPClient and Net::Managesieve that part of the code should be of a broader interest. If someone is interested to have a look or even wants to help make it again a more universal tool I have put the code on ftp://ftp-zeuthen.desy.de/pub/unix/mail/websieve.pl Current status: I have tested the creation and modification of sieve rules, inspecting and setting ACL's (dovecot 1.2), displaying quota and creating folders. All the other code (e.g. the part that deals with an administrative user) is untested and probably not compatible yet with the new perl modules used. -- Wolfgang Friebel Deutsches Elektronen-Synchrotron DESY Phone/Fax: +49 33762 77372/216 Platanenallee 6 Mail: Wolfgang.Friebel AT desy.de D-15738 Zeuthen Germany

[Dovecot] Script to install dovecot 1.2 plus Managerootsieve to CentOS5.2
by Bruce A. Mallett 07 Apr '09

07 Apr '09

I have no idea if this is of interest to anyone but it might save you some work .. I created a script that will install Dovecot 1.2-rc2 (currently) to a CentOS5.2 installation complete with Stephan Bosch's Managesieve, postfix, virtual users, LDAP, and LDAP personal address books. Oh right! .. and Squirrelmail plus various plugins (change LDAP password, LDIF import, Avelsieve). Also self-signed certificates are created from data supplied in a configuration file. I've stuck the required files here: http://www.nightstorm.com/~bam/CentOS5.2/ I did an install to a 32 bit CentOS so it has worked at least once on that architecture. It *should* work on a 64 bit as well (I provide the RPM) but I've not personally tested it. I am by no means an expert on any of this stuff (particularly the security aspects), so I'd certainly welcome any suggestions for ways to improve on the installation, the script, life, the universe, ... ;-) - Bruce
