[Dovecot] Dovecot 2.0beta3: Auth master process is now running as default_internal_user
by Thomas Leuxner 16 Mar '10

16 Mar '10

Hi, with 'changeset 10910' the Auth master process is running as 'default_internal_user' now (dovecot). This requires permissions tuning for 'passwd-files' at least, while other plugins would run in a different user context, 'vmail' in my setup. I see that this may be safer, just wondering how to streamline the config: [20:27] root spectre:/var/vmail/conf.d# l drwxr-x--- 4 dovecot vmail 4096 2010-03-14 17:40 leuxner.net [20:27] root spectre:/var/vmail/conf.d# l leuxner.net/ drwx------ 2 vmail vmail 4096 2010-03-14 13:09 acls -r-------- 1 dovecot vmail 125 2010-02-07 13:08 passwd drwx------ 2 vmail vmail 4096 2010-03-14 12:13 sieve [20:27] root spectre:/var/vmail/conf.d# cat leuxner.net/passwd tlx@leuxner.net:{SSHA}xxxx:5000:5000::/var/vmail/leuxner.net/tlx::userdb_quota_rule=*:storage=5G […] Regards Thomas

[Dovecot] ACL problem
by SZÉKELYI Szabolcs 16 Mar '10

16 Mar '10

Hey, I seem to have a problem with ACLs. I'm trying to use them on shared folders those work fine without it. But as soon as I enable the plugin and create the dovecot-acl files, they disappear. I used strace to see if there's a problem with file permissions, but it looks like Dovecot doesn't even attempt to access the dovecot-acl file in the maildir, only the dovecot-acl-list files. However, it does look for dovecot-acl files in users' home directories. Maybe the ACL plugin is enabled only for the private mailboxes, not for the public ones, but I want right the opposite. How can I achieve it? Please find my dovecot config below. Thanks, -- cc # 1.2.4: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-686 i686 Debian 5.0.4 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps ssl: required ssl_cert_file: /etc/ssl/certs/imapd.pem ssl_key_file: /etc/ssl/private/imapd.key.pem login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_privileged_group: mail mbox_write_locks: fcntl dotlock mail_plugins: acl namespace: type: private location: mbox:%h:INBOX=/var/mail/%u inbox: yes list: yes subscriptions: yes namespace: type: public separator: / prefix: Logs/ location: maildir:/data/mail/logs:LAYOUT=fs:INDEX=~/.imap- public/Logs:CONTROL=~/.imap-public/Logs list: yes auth default: passdb: driver: pam userdb: driver: passwd plugin: acl: vfile

[Dovecot] Dovecot 2.0beta3 LMTP hanging when delivering into a non-existing mailbox

[Dovecot] Authentication userdb file / configuration help - newbie question...
by Zilon X 16 Mar '10

16 Mar '10

Hi All, I need to configure Dovecot with a XMail server ( www.xmailserver.org ) - this server uses a userdb file with the following format: "domain"[TAB]"account"[TAB]"encrypted-passwd"[TAB]"account-id"[TAB]"account-dir"[TAB]"account-type"[NEWLINE] How can authenticate Dovecot against this userdb file? Was anyone doing that? Maybe, can I authenticate Dovecot using SMTP Auth? Thank you for any help!

[Dovecot] Dovecot 2.0b3: mdbox with incorrect ACL file permissions crashes
by Thomas Leuxner 16 Mar '10

16 Mar '10

Hi, played around with 'mdbox' format some more. Converted my personal mailbox with latest Dovecot and dsync from HG: dsync convert -u login(a)yourdomain.com mdbox:~/mdbox One thing I noticed is, that dsync does not take care of existing 'dovecot-acl' files, which it should migrate/copy from my point of view, but simply skips them. Anyway I copied over the ACLs manually and forgot to set the rights accordingly. So the files were owned by 'root:vmail' instead of 'vmail:vmail' in my setup. Voilà Dovecot crashed, where it should really throw a warning or ignore the owner and work with the group permissions: Mar 2 19:27:52 spectre dovecot: imap(tlx(a)leuxner.net): acl vfile: file /var/vmail/conf.d/leuxner.net/acls/Support/Serverloft not found Mar 2 19:27:52 spectre dovecot: imap(tlx(a)leuxner.net): acl vfile: no access to file /var/vmail/leuxner.net/tlx/mdbox/mailboxes/Support/Serverloft/dbox-Mails/dovecot-acl Mar 2 19:27:52 spectre dovecot: imap(tlx(a)leuxner.net): Panic: file acl-cache.c: line 295 (acl_cache_update_rights): assertion failed: (obj_cache->my_current_rights != &negative_cache_entry) Mar 2 19:27:52 spectre dovecot: imap(tlx(a)leuxner.net): Raw backtrace: /usr/lib/dovecot/libdovecot.so.0 [0x7f4d8595ffb2] -> /usr/lib/dovecot/libdovecot.so.0 [0x7f4d8596001a] -> /usr/lib/dovecot/libdovecot.so.0 (i_error+0) [0x7f4d859603c3] -> /usr/lib/dovecot/modules/lib01_acl_plugin.so [0x7f4d84da690b] -> /usr/lib/dovecot/modules/lib01_acl_plugin.so [0x7f4d84da4249] -> /usr/lib/dovecot/modules/lib01_acl_plugin.so [0 x7f4d84da4572] -> /usr/lib/dovecot/modules/lib01_acl_plugin.so [0x7f4d84da472e] -> /usr/lib/dovecot/modules/lib01_acl_plugin.so [0x7f4d84da2aba] -> /usr/lib/dovecot/modules/lib01_acl_plugin.so(acl_object_get_m y_rights+0x65) [0x7f4d84da2b85] -> /usr/lib/dovecot/modules/lib01_acl_plugin.so [0x7f4d84da8fd9] -> dovecot/imap [tlx(a)leuxner.net 84.58.106.99 STATUS](client_find_namespace+0x17f) [0x41149f] -> dovecot/imap [t lx(a)leuxner.net 84.58.106.99 STATUS](cmd_status+0xfc) [0x40dc2c] -> dovecot/imap [tlx(a)leuxner.net 84.58.106.99 STATUS] [0x40f9bc] -> dovecot/imap [tlx(a)leuxner.net 84.58.106.99 STATUS] [0x40fa6d] -> dovecot/imap [tlx(a)leuxner.net 84.58.106.99 STATUS](client_handle_input+0x45) [0x40fbe5] -> dovecot/imap [tlx(a)leuxner.net 84.58.106.99 STATUS](client_input+0x62) [0x410622] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handl er_run+0xcb) [0x7f4d8596abab] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x18) [0x7f4d85969d28] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f4d85959eb3] -> dovecot/imap [tlx(a)leuxner.n et 84.58.106.99 STATUS](main+0x191) [0x418661] -> /lib/libc.so.6(__libc_start_main+0xe6) [0x7f4d851e71a6] -> dovecot/imap [tlx(a)leuxner.net 84.58.106.99 STATUS] [0x4084e9] Mar 2 19:27:52 spectre dovecot: master: service(imap): child 30281 killed with signal 6 (core dumps disabled) Regards Thomas

[Dovecot] Shared folders
by Неворотин Вадим 16 Mar '10

16 Mar '10

I need to create a shared folder (mailbox for group mailing list) with access of several accounts to it. But all peoples with access to this mailbox should be able to work with this folder absolutely in the same way, as with local mailbox. Each user should be able to delete emails and mark it as readed. But this changes must be only for one user, not for others. For example user1 and user2 have access to folder Trades. There is a new incoming mail. User1 read it and delete. But in user2's client this mail must be not readed and not deleted. So there should be only one copy of a email (in group mailbox), but state (unreaded|readed|deleted) of this email shoud be different for each user. Can I do this with dovecot? Yes, I know that I can send a copy of group letter to each user's mailbox, but unfortunately I has a lot of groups and very big letters, so I can't duplicate each letter to many mailboxes. The purpose is to story only one instance of each letter, but to allow users to work with it like with their own letters. Now I use Maildir++ mailboxes.

[Dovecot] Quota plugin and SQL
by David 16 Mar '10

16 Mar '10

I have read through http://wiki.dovecot.org/Quota/Dict, which suggests a database schema for using quota. For 1.2, this includes a username, bytes and messages. Is there any way to modify the queries used to split out username into localpart and domain? This would enable me to put the current quota information in my main mailbox table and display it to users in my admin interface. Or possibly it should be in a separate table for a reason, and I should be look there for the values? Thanks, David
