[Dovecot] Shared mailboxes unix permissions
by Thomas Hummel 16 Apr '10

16 Apr '10

Hello Timo, I'm running dovecot-1.2.11/Maildir and plan to migrate to single UID mailboxes some day, but for now, I've got "system" users and I'm testing permissions handling in order to set up shared mailboxes. The private namespace mailboxes location is location = maildir:/courriel/boites/%u:CONTROL=/courriel/meta/%u:INDEX=/var/dovecot-test/indexes/%1u/%u I've . created a 'doveshared' unix group . added 'mail_access_groups = doveshared' . chmod/chgrp the maildir and control dirs like this : drwxrws--- 7 doveimap doveshared 4096 Mar 31 18:47 /courriel/boites/doveimap drwxrws--- 5 doveimap doveshared 4096 Mar 31 18:47 /courriel/meta/doveimap [which were empty] . added 'acl_shared_dict = file:/var/dovecot-test/dict/shared-mailboxes' with drwxrwxs-- 2 root doveshared 512 Mar 31 18:44 /var/dovecot-test/dict [which were empty] Everything gets created with the permission I was expecting, except : -rw------- 1 doveimap doveshared 8 Mar 31 18:47 /courriel/meta/doveimap/dovecot-uidvalidity -rw------- 1 doveimap doveshared 0 Mar 31 18:44 /courriel/meta/doveimap/dovecot-uidvalidity.4bb37be4 and -rw------- 1 doveimap doveshared 0 Mar 31 18:44 /var/dovecot-test/dict/shared-mailboxes I can't see the explanation in http://wiki.dovecot.org/SharedMailboxes/Permissions and the 'dovecot-shared' file doesn't help (besides, my understanding is that in 1.2x, it's for backward compatibility reason). Any idea ? Thanks -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] "try MD5-CRYPT scheme instead"?
by Ralf Hildebrandt 16 Apr '10

16 Apr '10

I'm getting a lot of entries like this in my log: Apr 16 10:10:18 postamt dovecot: auth(default): shadow(doxxxris,141.42.206.38): CRYPT(wrongpassword) != '$1$qSe71xxx$09MoMqNyll.wPLCdSaFuA0', try MD5-CRYPT scheme instead It seems that changing the password via SquirrelMail (poppasswd) breaks the authentication scheme somewhat. Users cannot log in anymore. -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebrandt(a)charite.de | http://www.charite.de

[Dovecot] Error in SimpleVirtualInstall
by Simone Neugierig 16 Apr '10

16 Apr '10

Hi, i still got a little Problem (Thunderbird cant copy my mail to "Gesendet") but besides that i can send and receive mail. ive used: http://wiki.dovecot.org/HowTo/SimpleVirtualInstall there it says that /etc/dovecot/passwd should look like: test:{PLAIN}pass bill:{PLAIN}secret timo@example.com:{PLAIN}hello123 dave@example.com:{PLAIN}world234 joe@elsewhere.org:{PLAIN}whee jane@elsewhere.org:{PLAIN}mypass but the syntax used for test and bill didnt work here, i had to add the virtual domain to get it working. or else deliver wasnt able to recognize the user (unknown user). Can anybody please confirm this? Also i would like to suggest to explicitely say that protocol lda { } is needed even if it contains nothing. or better change the example so that it contains the postmaster address. but the one in the howto just contains .. dovecot probably wont even start with that example. this is dovecot 1.2.11 -- GRATIS für alle GMX-Mitglieder: Die maxdome Movie-FLAT!

[Dovecot] dovecot2: authcache statistics
by Andreas Schulze 16 Apr '10

16 Apr '10

Hello, setting auth_cache_size to nonzero enables caching of authentication data. The cache hitrate may be logged by sending SIGUSR2 to dovecot/auth process. Is it possible that dovecot logs statistics on regular intervals ?

[Dovecot] manipulating mails
by Sven 16 Apr '10

16 Apr '10

Hi all, sorry for my inexperience. I am still learning. I searched for a while but found nothing useful. I am looking for the best way to manipulate headers, bodies, attachments, locations, folders and/or flags while using deliver and e.g. perl. In other words manipulating the whole mail in respect of the requirements of the LDA, MUA and User. I see two diffent ways. As i understand I can work via IMAP and pre-auth sessions, which keeps track of the index files from dovecot and handles complications with users already logged in. Can I use e.g. some perl imap module -> download the mail -> change it -> upload it again with all other parameters unchanged and no confusions on the user's side? This way I think its complex to rewrite the mail header/body/attachments as desired and keep everything else, eg times, flags, headers. the goal should be close to invisibility for a user. This maybe leads to open pre-authed sockets/ports and a lot of work. The other way would be to directly modify the file system. This keeps everything (i think), but changes mtime and needs some index file and MUA cache update. For performance reasons I would like to not use the index-automatism of dovecot but do it manualy at runtime of some script. How does the index update gets initialized from the outside? Same for the client cache. Is there some command available or is a IMAP login my workaround? This maybe leads to password problems or open pre-authed sockets/ports. Last question: Is it possible to add some received-tag to a mail-header when appending mails via imap to the mailbox? Can anyone turn my head in the desired direction? Thanks in advance Sven

dovecot.org gets more memory in a few hours, so it'll be down for a while (maybe max 30 mins?)

[Dovecot] version 1.2.11 creating symlink loop for config file
by Adrian Pepper 15 Apr '10

15 Apr '10

What is the following at the end of "main_init" in dovecot 1.2.11 (src/master/main.c) intended to accomplish? base_config_path = t_strconcat(settings_root->defaults->base_dir, "/"PACKAGE".conf", NULL); (void)unlink(base_config_path); if (symlink(configfile, base_config_path) < 0) { i_error("symlink(%s, %s) failed: %m", configfile, base_config_path); } } With our compilation parameters and runtime setup it ends up removing the working base_config_path file and making it instead a symlink to itself. (I.e. a non-working loop). Strangely, the one instance of dovecot continues and seems to mostly work. But (for now) I need to put back the proper dovecot.conf before I can restart it. I think that would be the expected result if strcmp(configfile, base_config_path) == 0. Is that in fact not expected to be the case? (See my initial question). I did not expect self-modifying of configuration like this. (See my initial question). Pattern matches (e.g. "config_path") find no apparent mention of this in recent postings.

[Dovecot] imap login fails with "no auth attempts"
by Niels Richter 15 Apr '10

15 Apr '10

Hi, I'm currently facing a strange behaviour of dovecot 1.2.10 (and before): after some days the login into our mail servers stops working for imap-connections. pop3-users can go on with using dovecot. Looking into the logfile I can only find: [...] imap-login: Disconnected (no auth attempts) imap-login: Disconnected: Shutting down (no auth attempts) [...] as a hint what is maybe happening. After restarting the system is working quite well again for some time. There is no extra load and not other special at the server running. The authentication is handled over mysql. This is our dovecot -n output (relevant parts): # 1.2.10: /usr/local/etc/dovecot.conf # OS: FreeBSD 7.2-STABLE i386 ufs protocols: imaps pop3s pop3 imap ssl_ca_file: /usr/local/etc/ssl/... ssl_cert_file: /usr/local/etc/ssl/... ssl_key_file: /usr/local/etc/ssl/... disable_plaintext_auth: no login_dir: /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 mail_max_userip_connections(default): 20 mail_max_userip_connections(imap): 20 mail_max_userip_connections(pop3): 10 verbose_proctitle: yes first_valid_gid: 0 mail_access_groups: mail mail_privileged_group: mail mail_location: maildir:/usr/... 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_process_size: 512 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 imap_client_workarounds(default): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(pop3): namespace: type: private prefix: INBOX. inbox: yes list: yes subscriptions: yes Do you see anything which is unclear or unnecessary and could lead to a crash of the imap-login process after some time? Thanks for your help! -- Niels.
