[Dovecot] quota ignore trash
by JC 23 Sep '07

Hi everybody, I have a server works good but the quota calculation includes trash, what i have to do in order to ignore trash in quota calculation? My server imap is dovecot 1.0, my smtp server is postfix 2.3.8-2 and my webmail is horde 3.1.3 and imp 4.1.3. my dovecot.conf : base_dir: /var/run/dovecot/ log_path: /var/log/mail.log log_timestamp: %Y-%m-%d %H:%M:%S protocols: pop3 imap 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 login_process_size: 64 login_processes_count: 5 login_max_processes_count: 256 login_max_connections: 512 first_valid_uid: 5000 last_valid_uid: 5000 first_valid_gid: 5000 mail_extra_groups: vmail mail_location: maildir:/home/vmail/%d/%n maildir_copy_with_hardlinks: yes maildir_copy_preserve_filename: 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 trash imap_quota mail_plugins(imap): quota trash 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 delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh namespace: type: private separator: . prefix: INBOX. inbox: yes auth default: mechanisms: plain login user: vmail passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: prefetch socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: vmail master: path: /var/run/dovecot/auth-master mode: 432 user: vmail group: vmail plugin: quota: maildir:storage=10240:messages=1000:ignore=Trash trash: /etc/dovecot/dovecot-trash.conf my dovecot-sql.conf : password_query = SELECT email AS user, password, '/home/vmail/%d/%n' AS userdb_home, 'maildir:/home/vmail/%d/%n' AS userdb_mail, 5000 AS userdb_uid, 5000 AS userdb_gid FROM users WHERE email = '%u' user_query = SELECT '/home/vmail/%d/%n' AS home, 'maildir:/home/vmail/%d/%n' AS mail, 5000 AS uid, 5000 AS gid, CONCAT('maildir:storage=', ROUND(quota/1000) ) AS quota FROM users WHERE email = '%u'

[Dovecot] kmail + IMAPS
by Timothy Murphy 23 Sep '07

23 Sep '07

I have dovecot IMAPS + kmail working perfectly on two laptops - I'm using one now - but I just tried starting it on a third laptop, and cannot get it running; kmail on the third laptop just waits indefinitely, saying "Retrieving Folder Contents Please wait ...". All 3 laptops are running Fedora 7, with more or less the same packages, all updated. (1) I suspect the problem lies with authentication. But how can I test this? Running "telnet <server> 993" gets the same response on all 3 laptops: [tim@elizabeth ~]$ telnet www.*.com 993 Trying 86.*.*.228... Connected to www.*.com. Escape character is '^]'. with no further response until I press ^]. I looked at <http://wiki.dovecot.org/TestInstallation> but this seems only to apply to IMAP on port 143. (2) kmail has an option to "Check What the Server Supports" under the Security tag, but pressing this just returns without any message, leaving whatever settings as they are. (On the laptops where kmail is working as an IMAPS client, the settings are changed to "Use TLS ..." and "Clear text".) I realise this is probably a kmail question, but shouldn't clicking on this option return some warning if it does not work? (3) I guess I don't understand exactly how TLS authentication works. Does installing openssl set up the correct certificates on server and client? Is there any documentation on this? Any suggestions or enlightenment gratefully received.

[Dovecot] recipient delimiter results in sieve errors
by Gregory Mokhin 23 Sep '07

23 Sep '07

Hello, I'm using dovecot 1.0.3 and Dovecot Sieve plugin 1.0.2. Sieve script works fine with normal addresses, like user@domain.., and messages marked with "X-Spam-Flag: YES" are delivered directly to INBOX.Spam. To make deliver understand recipient_delimiter I tried two methods, the first one as per wiki (tweaking postfix master.cf), and the second one by tweaking dovecot-sql.conf (the main idea is to use concat(substring_index('%n',"+',1),'@','%d') for the username). Both methods work good. However when deliver processes sieve script for the addresses with a delimiter, user+ext(a)domain.tld, there is an error: deliver(test@k..): Info: cmusieve: Using sieve path: /home/vmail/.dovecot.sieve deliver(test@k..): Info: cmusieve: Executing script /home/vmail/.dovecot.sievec deliver(test@k..): Info: sieve runtime error: Keep: Generic Error deliver(test@k..): Error: sieve_execute_bytecode(/home/vmail/.dovecot.sievec) failed deliver(test@k..): Info: msgid=<..@mail...>: saved mail to INBOX In that case message is delivered to INBOX, not to INBOX.Spam Regards, Gregory

[Dovecot] Binary packagers: BSD license issues
by Timo Sirainen 23 Sep '07

23 Sep '07

Adding this SHA256 code made me read the BSD license once again. It says: * 2. Redistributions in binary form must reproduce the above copyright * notice, this list of conditions and the following disclaimer in the * documentation and/or other materials provided with the distribution. Then there are a few files from Cyrus as well which contain: * 4. Redistributions of any form whatsoever must retain the following * acknowledgment: * "This product includes software developed by Computing Services * at Carnegie Mellon University (http://www.cmu.edu/computing/)" And something similar in utc-mktime.c for Berkeley university as well. I think I'd really like to get rid of those base64.c and utc-mktime.c exceptions.. There's probably also an easier/faster way to implement utc_mktime(). Anyway.. Currently these copyrights or acknowledgments aren't listed anywhere else than in the source files. I don't know if binary packagers have added those, but somehow I doubt it. So I think I should add these to COPYING file somehow. Any suggestions?

[Dovecot] IDLE with inotify problem
by Michael Guntsche 23 Sep '07

23 Sep '07

Hi, I recently switched from courier imap to dovecot. With courier I had a working IDLE setup that informed me immediately when new mail arrived. With Dovecot it is different, sometimes i get an immediate result but most of the time it takes a rather long time for the notification to return to the client. For testing purposes I set mailbox_idle_check_interval = 1 and i now get the same behaviour as with couier (a new mail immediately causes a notification) but i am not sure that this is the right solution. Reading the comments in the config files I was under the impression that this is not needed if dovecot uses inotify. Setup: Kernel 2.6.22.1 with inotify dovecot 1.0.3 from debian unstable Build options: ioloop=epoll notify=inotify ipv6 openssl So my question is can I check that dovecot is actually using inotify? Kind regards, Michael

[Dovecot] Problems with quota dict in 1.1.alpha4
by arvids 22 Sep '07

22 Sep '07

Hello, there are problems with quota dict when multiple dovecot deliver processes are launched in parallel. It can be reproduced by sending a mail with multiple different recipients - the mail is delivered OK to all recipients, but the quota are not updated correctly in sql. I looked at the code and it seems that the problem is somewhere in dict cache. If I configure in Postfix max number of deliver processes to 1, dict quota is updated correctly. postconf -n output: # 1.1.alpha4: /usr/local/dovecot/etc/dovecot.conf base_dir: /var/run/dovecot/ syslog_facility: local0 protocols: pop3 ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/dovecot/libexec/dovecot/pop3-login login_greeting: Server. login_process_per_connection: no login_process_size: 64 verbose_proctitle: yes first_valid_uid: 95 first_valid_gid: 95 mail_uid: 95 mail_gid: 95 mail_location: maildir:~/Maildir mail_debug: yes fsync_disable: yes mail_executable: /usr/local/dovecot/libexec/dovecot/pop3 mail_plugins: quota mail_plugin_dir: /usr/local/dovecot/lib/dovecot/pop3 pop3_enable_last: yes pop3_client_workarounds: outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login digest-md5 cram-md5 apop cache_size: 2048 cache_ttl: 28800 cache_negative_ttl: 60 user: doveauth verbose: yes debug: yes debug_passwords: yes passdb: driver: sql args: /usr/local/dovecot/etc/dovecot-sql.conf userdb: driver: prefetch userdb: driver: sql args: /usr/local/dovecot/etc/dovecot-sql.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 user: vmail group: vmail plugin: quota: dict:::proxy:/var/run/dovecot/dict-server:quotadict dict: quotadict: mysql:/usr/local/dovecot/etc/dovecot-sql-dict-quota.conf Regards, Arvids

[Dovecot] Feature Request for Proxy
by Ed W 22 Sep '07

22 Sep '07

Hi, Quick feature request for the proxy function: I have a couple of machines which are all customer facing and customer mailbox lives on any one of them. Customer can login to any machine and the proxy feature then forwards them to the correct machine (often the machine they are already connected to). However, right now if the SQL query simply returns the IP of the correct machine, and this happens to be the same machine that the connection is already on, then we get the auth process stuck in an infinite loop (and generating a lot of log files...) The quick fix is to customise each installation and add some kind of WHERE clause to change the results IF result is already the same as the machine we are on. However, this is error prone when setting up new machines and it's easy to forget or make a typo adjusting the config files. In my case I am using vservers and it's quite neat to be able to simply copy the whole image and fire it up on a new IP to test an upgrade, etc, hence easy to mess up adjusting the conf files when creating a new image. Any suggestions on how this could be done more dynamically, or else could I raise a feature request that the auth process somehow realises when it's being forwarded to an IP address that it's actually listening on already already (ie it's a request which loops back to itself), thus simplifying the config files? I haven't cracked open the code, but it sounds somewhat possible to check the list of IP addresses we are currently listening on and check that the proxy dest isn't among them? Cheers Ed W

[Dovecot] maildir rename_subfolders() and listescape interaction
by pod 22 Sep '07

22 Sep '07

I'd like to flag a problem we are observing that looks like it is caused by the listescape-plugin.c. I realize that this plugin is not part of the standard Dovecot 1.0 distribution but I would appreciate any insights or suggestions for fixes that anyone is kind enough to offer. The problem concerns subfolder renames when used in conjunction with Maildir folders (I've not tested this against any other folder type). Without listescape plugin: mail_location: maildir:%h/Maildir:INDEX=%h/index:CONTROL=%h/control mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota namespace: type: private separator: / inbox: yes 01 LIST "" * * LIST (\HasNoChildren) "/" "INBOX" 01 OK List completed. 02 CREATE a 02 OK Create completed. 03 CREATE a/b 03 OK Create completed. 04 LIST "" * * LIST (\HasChildren) "/" "a" * LIST (\HasNoChildren) "/" "INBOX" * LIST (\HasNoChildren) "/" "a/b" 04 OK List completed. 05 RENAME a c 05 OK Rename completed. 06 LIST "" * * LIST (\HasChildren) "/" "c" * LIST (\HasNoChildren) "/" "INBOX" * LIST (\HasNoChildren) "/" "c/b" 06 OK List completed. 07 LOGOUT * BYE Logging out 07 OK Logout completed.

Seemingly the only relevant log entry is @4000000046d70d8f1f72b66c dovecot: Error: IMAP(pod): rename(/srv/mail/home/test0/pod/Maildir/.a/b, /srv/mail/home/test0/pod/Maildir/.c/b) failed: No such file or directory Note the response to tag 05 in each case. The 06 list response in the listescape case is not unexpected given the nature of the failure. My initial reading of rename_subfolders() from maildir-storage.c suggests that the calls through maildir_mailbox_list_init() and maildir_mailbox_list_next() are returning "external" style names (i.e. ones that present "/" as the hierarchy separator) to rename_subfolders(), which is an "internal" helper function. This is supported by the logged error message. I am afraid I am yet to get my head around the actual code path and the escaping and unescaping that is going on so am not able to suggest a fix as yet.
