[Dovecot] Problem with hard links in lda - please help
by Fabio Ferrari 26 Jul '10

26 Jul '10

Hello, I'm trying to enable hardlinks for messages sent to mutiple users. (I need this because I have mailing lists with 5000 users used many times a day). I've read that, to do this, I have to write a script that uses the /usr/local/libexec/dovecot/deliver command in this way: deliver -p <FILE> -d <USER1> -d <USER2> Of course, I enabled the "socket listen" option in the configuration file to get the command line work, and set the maildir_copy_with_hardlinks = yes The deliver command works, so I have the messages correctly in the "new" directory in the maildir folder. But if I list the files, they have the "links" number = 1, so I see that the file was copied, not hardlinked! I see in the page http://wiki.dovecot.org/LDA that is possible, in fact it says Parameters [...] -p <path>: Path to the mail to be delivered instead of reading from stdin. If using maildir the file is hard linked to the destination if possible. This allows a single mail to be delivered to multiple users using hard links, but currently it also prevents deliver from updating cache file so it shouldn't be used unless really necessary. (v1.1+) Of course, I use a version 1.1+ (1.2.12). Please help, thanks in advance Fabio Ferrari

Hello, For my manager I need to write a script to extract the From: e-mail addresses from his e-mail account. Then they are sent invitations to join our mailing list(s). I inherited this Dovecot server, I have not done anything with Dovecot before. Could you give me some direction on if/how can this be done? We run Dovecot 1.0.1 (dovecot --version) Thank you, Iv

[Dovecot] antispam plugin troubleshooting
by Bradley Giesbrecht 26 Jul '10

26 Jul '10

I built the dovecot antispam plugin and renamed it so I could have multiple backends installed at the same time. http://johannes.sipsolutions.net/Projects/dovecot-antispam I tried recompiling antispam without renaming the .so and I get the same result indicated below. All other plugins and the system as a whole has been functioning normally. Only when I add antispam plugin does dovecot not start and perform as expected. What can I do to find the reason dovecot is not loading lib90_antispam_mailtrain_plugin.so successfully? Below is some info I could think to supply for help. Regards, Bradley Giesbrecht Mac OS X 10.5.8 dovecot antispam plugin 1.3 bash-3.2# tail -f /var/log/system.log | grep dovecot Jul 25 13:51:07 trex org.macports.dovecot[10354]: ^AILoading modules from directory: /opt/local/lib/dovecot/imap Jul 25 13:51:07 trex org.macports.dovecot[10354]: ^AIModule loaded: / opt/local/lib/dovecot/imap/lib20_autocreate_plugin.so Jul 25 13:51:08 trex org.macports.dovecot[10354]: Error: imap dump- capability process killed with signal 11 Jul 25 13:51:08 trex org.macports.dovecot[10354]: Fatal: Invalid configuration in /opt/local/etc/dovecot/dovecot.conf bash-3.2# file /opt/local/lib/dovecot/imap/ lib90_antispam_mailtrain_plugin.so /opt/local/lib/dovecot/imap/lib90_antispam_mailtrain_plugin.so: Mach-O executable ppc bash-3.2# dovecot --version 1.2.11 bash-3.2# dovecot -n # 1.2.11: /opt/local/etc/dovecot/dovecot.conf # OS: Darwin 9.8.0 Power Macintosh hfs log_path: /opt/local/var/serveza/log/mail/dovecot.log protocols: imap imaps pop3 pop3s managesieve listen(default): * listen(imap): * listen(pop3): * listen(managesieve): *:2000 disable_plaintext_auth: no login_dir: /opt/local/var/run/dovecot/login login_executable(default): /opt/local/libexec/dovecot/imap-login login_executable(imap): /opt/local/libexec/dovecot/imap-login login_executable(pop3): /opt/local/libexec/dovecot/pop3-login login_executable(managesieve): /opt/local/libexec/dovecot/managesieve- login mail_max_userip_connections: 30 mail_location: dbox:/opt/local/var/serveza/mail/%d/%n/dbox mail_debug: yes mail_executable(default): /opt/local/etc/dovecot/bin/log_imap_login.sh mail_executable(imap): /opt/local/etc/dovecot/bin/log_imap_login.sh mail_executable(pop3): /opt/local/etc/dovecot/bin/log_pop3_login.sh mail_executable(managesieve): /opt/local/libexec/dovecot/managesieve mail_plugins(default): autocreate antispam_mailtrain mail_plugins(imap): autocreate antispam_mailtrain mail_plugins(pop3): mail_plugins(managesieve): mail_plugin_dir(default): /opt/local/lib/dovecot/imap mail_plugin_dir(imap): /opt/local/lib/dovecot/imap mail_plugin_dir(pop3): /opt/local/lib/dovecot/pop3 mail_plugin_dir(managesieve): /opt/local/lib/dovecot/managesieve lda: postmaster_address: postmaster(a)pixilla.com hostname: ix.databoost.com sendmail_path: /opt/local/sbin/sendmail auth_socket_path: /opt/local/var/run/dovecot/auth-master log_path: /opt/local/var/serveza/log/mail/dovecot-deliver.log mail_plugins: sieve auth default: mechanisms: plain login cram-md5 ntlm apop debug: yes passdb: driver: sql args: /opt/local/etc/dovecot/dovecot_mysql.conf userdb: driver: prefetch userdb: driver: sql args: /opt/local/etc/dovecot/dovecot_mysql.conf socket: type: listen client: path: /opt/local/var/spool/postfix/private/auth mode: 432 user: _postfix group: _postfix master: path: /opt/local/var/run/dovecot/auth-master mode: 384 user: _vmail plugin: sieve_before: /opt/local/var/serveza/mail/filter/sieve/global/before/ sieve: /opt/local/var/serveza/mail/filter/sieve/%d/%n/active.sieve sieve_global_path: /opt/local/var/serveza/mail/filter/sieve/global/ default.sieve sieve_dir: /opt/local/var/serveza/mail/filter/sieve/%d/%n/sieve sieve_global_dir: /opt/local/var/serveza/mail/sieve/global/include/ sieve_after: /opt/local/var/serveza/mail/filter/sieve/global/after/ autocreate: Trash autocreate2: Spam autosubscribe: Trash autosubscribe2: Spam antispam_mailtrain_signature: X-DSPAM-Signature antispam_mailtrain_signature_missing: error antispam_mailtrain_trash_pattern_ignorecase: trash;Deleted * antispam_mailtrain_spam_pattern_ignorecase: SPAM*;Junk* antispam_mailtrain_dspam_binary: /opt/local/bin/dspam antispam_mailtrain_mail_tmpdir: /tmp antispam_mailtrain_mail_sendmail: /opt/local/sbin/sendmail antispam_mailtrain_crm_binary: /bin/false

[Dovecot] imap core dumping on signal 10
by Chris Hoogendyk 25 Jul '10

25 Jul '10

We are just trying to bring up a new server and chose to use Dovecot rather than the uw-imap from our previous servers. At this point I am just testing with some throw away accounts using squirrelmail. I can load my inbox, but then the imap connection is lost. I presume you need some real information to get your teeth into, so this is going to get a little long. I'll give you three things below: 1. a piece of /var/adm/dovecot.log, 2. the output of `dovecot -n`, and then 3. the full gdb trace back on the core file. I'm hoping that, aside from there being a bug that causes core dumps, we might have a straightforward misconfiguration that we could fix and have a working installation.

[Dovecot] v1.2.13 released
by Timo Sirainen 25 Jul '10

25 Jul '10

http://dovecot.org/releases/1.2/dovecot-1.2.13.tar.gz http://dovecot.org/releases/1.2/dovecot-1.2.13.tar.gz.sig This release fixes a bug in ACL plugin, which could be considered a security bug: If Maildir is used with default settings (INBOX is same as Maildir root dir) and user set some ACLs to INBOX, those ACLs were copied to all newly created mailboxes. This should have been done only for "default ACLs", but with Maildir the INBOX directory is the same as the default ACL directory, so this mixup happened. This bug exists only in v1.2.x releases. Other fixes: - Fixed iconv() crash when it was processing several kilobytes of broken continuous input. This mainly could have caused a problem with IMAP SEARCH. Possibly also with some Sieve checks. - If MIME encoded-words contained line feeds, Dovecot logged cache corruption errors. - mbox: Renaming mailbox under newly created dir didn't move index directory. - mbox: When generating envelope to From_-line, don't append a second @owndomain if username already has one.

[Dovecot] Shared folders issue
by Emmanuel Gonzalez Carmona 23 Jul '10

23 Jul '10

Hello guys, I have an issue with shared folders: 1) The USERA shares his INBOX with USERB 2) USERB subscribes the USERA share without problems. 3) USERA deletes all his / or some directories from his INBOX (Trash, Drafts and Sent) 4) USERA logouts and makes login, so dovecot recreates the folders. 5) USERB gains access to subscrive those folders (Trash, Drafts and Sent) this is my namespace configuration: ... namespace private { separator = / prefix = inbox = yes #list = yes #subscriptions = yes } namespace shared { separator = / prefix = "shared/%%u/" location = maildir:/maildirs/%%d/%%u/Maildir subscriptions = no list = children } ... any ideas?

hi, we are using the dovecot-rc1 version, and we are testing the director service, as there is little documentation on this service, a pair of questions.. if i'm not wrong, the proxy_maybe it's not implemented, yet? will be soon? this limitation does not allow use the same two directors servers like mail backend servers? the fairlure of one director server it's automatically detected or require manual intervention? thanks and sorry for so many questions...

[Dovecot] Doveadm protocol for parallel user processing
by Timo Sirainen 23 Jul '10

23 Jul '10

A lot of doveadm commands process users' mails. They can optionally process either a single user or multiple users (e.g. -A = all, -u '*(a)domain.org'). For example to expunge old mails from everyone's Trash, you'd use: doveadm expunge -A mailbox Trash savedbefore 30d The problem is, this doesn't work with the new director way of doing proxying. Only a single server can access a user's mails safely, so this command can't be run safely if there are multiple mail servers. It's also a bit problematic for regular proxying, but it's especially problematic with director: Since users aren't permanently assigned anywhere, it's not even possible to build a user <-> host mapping and run the command only for those users in their assigned server. First I started thinking about adding another lib-storage backend that supports proxying to another server, maybe via IMAP or maybe via another protocol. Maybe I should do that some day anyway, but it seems a bit complex for this task. Then I also realized that even if all users are on local server, it would probably finish faster if doveadm could handle users in parallel in separate processes (due to disk I/O latencies and maybe other latencies). So, it seems like it would be a good idea to make doveadm internally a client/server architecture. When you start doveadm, it would be only the "brain" part, which connects to the worker doveadms either via local UNIX socket or to remote servers. Admin could configure how many doveadm worker processes the brain should connect per server (could be a per-server setting). So, what's needed to make this happen? 1. The actual client/server split and the protocol. Probably can be really simple and won't be anything interesting. Or maybe it becomes more interesting once I start thinking about it more, we'll see. :) 2. Authentication. 3. TLS-protection? After merging code from dovecot-2.0-sslstream branch this should be pretty easy. Although Dovecot should finally then add support for checking that CommonName/etc match the server name. Authentication -------------- For local UNIX sockets that are 0600 root, the authentication wouldn't be necessary. It could internally check that if the listener socket has these permissions, it would just announce that doveadm is already authenticated. Otherwise, and especially for TCP connections, there should be authentication. I was thinking about using already existing master users for this. Doveadm client says "I'm <masteruser>, my password is <pass>, and I want to access <user>'s mails". Auth process does the authentication and replies either success or failure, just like for similar IMAP/POP3/etc logins. It's possible to restrict what users a master user can log in as, like admin(a)domain.org could only log in as *(a)domain.org. This means that you could also enable doveadm protocol for external users, and let the domain administrators use doveadm directly to manage their own domain's users. PLAIN authentication mechanism would be easy to support. But this might be a good time to also introduce client side SASL library to Dovecot to support other auth mechanisms. But then again, maybe it doesn't really matter.. Privilege dropping ------------------ I hate it that with multiple UIDs doveadm processes currently have to be run as root and they only temporarily drop privileges. With client/server split it would be possible to get rid of this. Each doveadm worker process would then handle only a single user and then exit. This would be optional similar to how login processes are now, e.g.: service doveadm { # 1 = default = one user access per process, 0 = unlimited user accesses service_count = 1 } LMTP privilege dropping ----------------------- Completely unrelated to doveadm, but due to the above doveadm privilege dropping thinking I also started thinking about LMTP. It's also annoying that it runs as root, and only temporarily drops privileges. It could also avoid this by saving a mail only to a single user per process. The problem is that there can be multiple RCPT TO:s in a same session, but this can be handled by treating them similarly than when using LMTP proxying: Just connect to localhost again and proxy the mail there for each user separately. This could also be optionally done only when the process UID differs from the destionation user's UID. When? ----- These are too invasive changes to v2.0, so I guess they'll wait until v2.1. Luckily there won't be any hugely destabilizing changes going into v2.1, so maybe v2.1.0 release won't be too many months after v2.0.0. :)

[Dovecot] quota-warning example script from wiki2
by Daniel Luttermann 22 Jul '10

22 Jul '10

Hi, in the wiki there's an example script for sending an email to an user that has exceeded his quota. Link: http://wiki2.dovecot.org/Quota/Configuration The dovecot deliver command line is: dovecot-lda -d $USER -o "plugin/quota=maildir:User quota:noenforcing" I wonder about -o: seems to be "undocumented" because I've found no information about this parameter. If this parameter is needed what if I use dict instead of maildir? Is the syntax different? Thanks. -- Daniel

[Dovecot] v2.0.rc3 released
by Timo Sirainen 22 Jul '10

22 Jul '10

http://dovecot.org/releases/2.0/rc/dovecot-2.0.rc3.tar.gz http://dovecot.org/releases/2.0/rc/dovecot-2.0.rc3.tar.gz.sig A lot of dsync fixes. I think I've fixed now all of the bugs ever reported about dsync and I'm hopeful that it's now stable. All the rest of Dovecot looks pretty good too. Maybe v2.0.0 will be out next week. Changes since rc2: * Single-dbox is now called "sdbox" instead of "dbox". "dbox" will stay as an alias for it for now. + Added mail_temp_dir setting, used by deliver and lmtp for creating temporary mail files. Default is /tmp. + doveadm: Added "director map" command to list user -> host mappings. - imap: Fixed checking if list=children namespace has children. - director: If all login processes died, director stopped reading proxy-notify input and caused future login processes to hang - mail_log plugin configuration was broken - Using more than 2 plugins could have caused broken behavior - mdbox: Race condition fixes related to copying and purging - dsync: Lots of fixes

Hello Everyone....

[Dovecot] doveadm mailbox create -7 … returns 0
by Pascal Volk 22 Jul '10

22 Jul '10

Hi Timo, I'm using doveadm in my script to create [sm]dboxes. For some reason I forgot to remove the -7 option in my script. I wondered why no mailboxes were created and the script didn't report an error - it checks the exit status from doveadm. The problem: doveadm mailbox create -7 … returns 0 Regards, Pascal -- The trapper recommends today: f007ba11.1020305(a)localdomain.org

[Dovecot] NFS Maildirs
by Martijn de Munnik 22 Jul '10

22 Jul '10

Hi, We have our user homedirs on nfs so I enabled nfs parameters in dovecot.conf. Everything works fine but when I want to delete a homedir of a user I can't delete it because I can't remove the .nfs files in the Maildir. I don't want to stop dovecot, remove the homedir and start dovecot. Is there another way to accomplish this. Thanks, Martijn # 1.2.12: /etc/opt/redknot/dovecot.conf Warning: fd limit 256 is lower than what Dovecot can use under full load (more than 4096).

[Dovecot] Applemail did not sync when MailTags enabled
by mailinglists＠belfin.ch 22 Jul '10

22 Jul '10

Hi I run dovecot 1.2.11. One of my users turned on MailTags in his AppleMail with the effect that he could not anymore synchronize his imap folders. No error message, just endless waiting. Has anybody experienced a similar behaviour? Thanks John
