[Dovecot] Dovecot discards mail over quota
by Gary V 27 Jan '09

27 Jan '09

I'm new to Dovecot, using 1.1.8 and I just wanted to verify that what I am observing is the intended behavior. I'm using Maildir++ quota. When a message is delivered to a mailbox that cannot accept the message because it would place them over the quota limit, deliver states to the MTA that the messsage was delivered successfully (example using postfix): Jan 17 12:05:31 msa postfix/pipe[13983]: 088C5B9D47: to=<test(a)example.com>, relay=dovecot, delay=0.72, delays=0.34/0.02/0/0.36, dsn=2.0.0, status=sent (delivered via dovecot service) But in actuality the mail is discarded (dropped). Then a bounce is created stating the mail was rejected: Your message to <test(a)example.com> was automatically rejected: Quota exceeded (mailbox for user is full). Question: is it possible (without changing code) to alter this to where deliver would instead tempfail or something. Somehow it seems wrong to me to tell the MTA that everything is good, and then silently discard messages - regardless of the fact dovecot creates a bounce. This is not necessarily ideal either, but I _am_ wondering if this is configurable or not. deliver(test(a)example.com): 2009-01-17 12:05:31 Info: msgid=<1293474859.20090117120812(a)example.com>: save failed to INBOX: Quota exceeded (mailbox for user is full) deliver(test(a)example.com): 2009-01-17 12:05:31 Info: sieve runtime error: Keep: Generic Error deliver(test(a)example.com): 2009-01-17 12:05:31 Error: sieve_execute_bytecode(/var/sieve/global.sievec) failed deliver(test(a)example.com): 2009-01-17 12:05:31 Info: msgid=<1293474859.20090117120812(a)example.com>: rejected: Quota exceeded (mailbox for user is full) deliver(garyv(a)example.com): 2009-01-17 12:05:31 Info: msgid=<dovecot-1232219131-401523-0@msa>: saved mail to INBOX -- Gary V

[Dovecot] behavior of dovecot with Openldap
by Masaharu Kawada 27 Jan '09

27 Jan '09

Dear team, I'm sorry if this is a stupid question, but I'd like to know the behavior of dovecot in a particular stuation. My questions are as follows. In /etc/dovecot-ldap.conf, 'hosts=' field is the one which can be used to specify availabled ldap server to access from the clients to authorize. And also sevral ldap servers can be specified in 'hosts =' field as shown like below. hosts = ldap-server1.example.com ldap-server2.example.com ※both server have the same configuration and available to replication ldap-server1(master) to ldap-server2(slave). If this is right, how does dovecot know which ldap server is currently used? and if the master dies, how does dovecot know and switch to slave one? In addition, which one is the exact behavior of dovecot in case master server dies? 1. only swithcing to the slave server 2. switching to the slave server, and once the master server is reactive then switch back to the master server automatically OS：RHEL4 U3 kernel 2.6.9-34.ELsmp openldap-2.2.13-12.el4 Thanks in advance, Masaharu Kawada ------------------- Masaharu Kawada Associate Global Support Engineer Red Hat K K Ebisu Neonato 8F 1-18 Ebisu 4-chome, Shibuya-ku Tokyo 150-0013, Japan Direct: +81-3-5798-8482

[Dovecot] FOLDER INTERNAL DATA (uw pine header)
by Charles Gregory 26 Jan '09

26 Jan '09

Hello! I run Dovecot on CentOS 4 (dovecot-1.1.4-0_81.el4), and I *also* run the "Alpine" mail system that comes with that OS. Alpine still writes out the 'FOLDER INTERNAL DATA' pseudo-message at the beginning of each user's mbox, but dovecot does not. I make use of that record as a simle/quick way to verify when a user actually last read their e-mail (for administrative purposes, identifying stale/unused accounts), so is there any way to configure/command dovecot to write (or update) these hidden messages? (Note: I tried looking in the archives, but most references seemed to be about this message being a 'side effect' of transferring *from* UW IMAP, and how to get 'rid' of it. Not what I need. :) Apologies if this was covered before in a different thread.) - Charles

[Dovecot] uint_cmp bug
by Mike Abbott 26 Jan '09

26 Jan '09

In reviewing the differences between 1.1.8 and 1.1.9 I saw a probable bug in the new function uint_cmp() in src/lib-storage/index/maildir/ maildir-sync-index.c: if (*i1 < *i2) return -1; else if (*i1 > *i2) return -1; else return 0; The second case should return 1 not -1.

[Dovecot] Released ManageSieve v0.10.5 for Dovecot v1.1.9
by Stephan Bosch 26 Jan '09

26 Jan '09

Hello Dovecot users, Because there was a crash bug in the ManageSieve v0.10.4 login daemon, I made a new release of the ManageSieve service for Dovecot v1.1. This release includes two other small fixes as well. Changelog v0.10.5: - Fixed a segfault bug in the authentication time-out. Bug report and trace provided by Wolfgang Friebel. - Fixed maximum permissions for uploaded scripts; was 0777. This was shielded however by the default umask (not documented to be configurable), so the actual permissions would never have been 0777. - Fixed handling of ~/ in use of mail-data for script location The following files are released: ManageSieve package: http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.5.tar.gz http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.5.tar.gz.s… ManageSieve patch: http://www.rename-it.nl/dovecot/1.1/dovecot-1.1.9-managesieve-0.10.5.diff.gz http://www.rename-it.nl/dovecot/1.1/dovecot-1.1.9-managesieve-0.10.5.diff.g… Have fun testing the new releases and don't hesitate to notify me when there are problems.

[Dovecot] userdb didn't return a home directory with v1.1.7

Hi all, I am running Dovecot v1.1.7 in a relatively quiet and calm environment. Suddenly overnight cron job has started throwing out errors like: /usr/sbin/dovecot --exec-mail ext /usr/lib/dovecot/expire-tool Error: userdb(user1(a)mail.example) didn't return a home directory Error: userdb(user2(a)mail.example) didn't return a home directory Indeed, running this command produces: ------------------------- $ sudo /usr/sbin/dovecot --exec-mail ext /usr/lib/dovecot/expire-tool --test Error: userdb(user1(a)mail.example) didn't return a home directory Info: User lookup failed: user1(a)mail.example Error: userdb(user2(a)mail.example) didn't return a home directory Info: User lookup failed: user2(a)mail.example ------------------------- Yet these mailboxes are valid, corresponding users can login, send and receive mail. Other mailboxes are OK, too. Where to to start looking? I found that similar error message with v1.1.6 is fixed in v1.1.7, but I am running v.1.1.7 already. Please see dovecot configuration below.

[Dovecot] Shared Mailboxes (symlink) and kmail: known issues?
by Wilhelm Meier 26 Jan '09

26 Jan '09

Hi, are there any known issues with symlinked-shared-mailboxes and kmail? I use virtual users (LDAP), so there are no unix-permissions related problems here: all mailboxes are owned by the local user vmail. Each user maildir has some symlinks to shared mailboxes. This works fine if I use squirrelmail as a MUA. kmail instead seems to have some problems: if I save a mail into the shared-folder, the other users are seeing this new mail almost immediately. But if I delete(!) a mail from the shared-folder, the list of the other kmails remains untouch. Refreshing does nothing. I have to close kmail and restart. Is this related to some sort of wrong config of the shared mailboxes or is this a (known) dovecot <-> kmail problem? -- Wilhelm

[Dovecot] Shared mailboxes support status
by Thomas Hummel 26 Jan '09

26 Jan '09

Hello Timo, I'm running dovecot-1.1.8 and I'm about to play with namespaces and shared mailboxes. I've read on the list that the Kolab people did contribute to that, and I read at http://dovecot.org/doc/NEWS-1.2 "+ Full support for shared mailboxes and IMAP ACL extension." I'd like to know the differences between shared mailboxes support between 1.1. and 1.2 branches and if it may be considered "safe" to use shared mailboxes on a production server running 1.1.8+ dovecot version (i.e. is it working and how, compared to the upcoming 1.2 release). I guess part of the answer is in the diffences between shared and public namespaces handling.

by Allison Vollmann 26 Jan '09

26 Jan '09

Hello, i want to get the maildir current quota usage of an user, but i'd know what is the better way to do. in imap clients my quota usage, in example, show: 505KB, but if i sum only the size of each message from Maildir, i get total: 440KB, trying to use real and apparent block size but the sum differs from value showed in imap client. is quota usage based on why, have another way to do this? thanks

[Dovecot] Postfix and Dovecot
by Leonardo Coelho 26 Jan '09

26 Jan '09

Hi Everybody, I'm mount two failover servers which use Postfix and Dovecot but the hostname of the machines r diferent: first node # uname -n # mail secound node #uname -n #mail2 So far so good, the real problem is that the e-mail file name on server is like this: 1232449377.P31789Q0M963611.mail2 and when I using the server called mail the file stay like this: 1232449377.P31789Q0M963611.mail I'm using drbd disk for the mailboxes and when I'm using the server called mail the files with mail2 on the end is not read for the dovecot when the user turn on the mail client but if I change the end from mail2 to mail that's ok the dovecot can read. How can I make dovecot read both files or any name on the end?

I tried adding it to global, and it didn't change anything, but then I just realized that I still had it in LDA, and so once I removed that part, and only have the configuration in global, it works! Thank you very much for your help Noel. :) Cheers -- John Reese LeetCode.net

[Dovecot] Dovecot upgrade broke per-user Sieve scripts
by John Reese 25 Jan '09

25 Jan '09

Hi all, I'm migrating my private mail server from Dovecot 1.0.10 to Dovecot 1.1.4 (both the latest package in Ubuntu Hardy and Intrepid, resp.). I'm using Postfix with Postfixadmin virtual users , passing mail to Dspam, which in turn passes email to the Dovecot LDA. The relevant configuration section is attached below. When running on the old version of Dovecot, the LDA correctly executed either the user's personal sieverc script, or the global sieverc, as expected. However, after the upgrade to 1.1.4, Dovecot will not execute any per-user Sieve scripts, although the configuration and file permissions hasn't changed. I've added debug logging to Dovecot, and the relevant portions of the log file are also attached below. What am I missing here? Why can't cmusieve find the user's script? Did the configuration for Sieve change? I've read and re-read the Dovecot wiki page for Sieve, and I can't see why my configuration should be causing any troubles. All help or suggestions are greatly appreciated. Thank you. ### dovecot.conf protocols = imap imaps disable_plaintext_auth = no mail_debug = yes log_path = /var/log/dovecot.log info_log_path = /var/log/dovecot.log mail_location = maildir:/srv/mail/%u/Maildir first_valid_uid = 900 ssl_cert_file = /srv/ssl/dovecot.pem ssl_key_file = /srv/ssl/leetcode.net.key auth default { mechanisms = plain login passdb sql { args = /srv/etc/dovecot/dovecot-mysql.conf } userdb sql { args = /srv/etc/dovecot/dovecot-mysql.conf } socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 user = vmail } client { path = /var/spool/postfix/private/auth mode = 0600 user = postfix group = postfix } } } protocol lda { log_path = /srv/mail/dovecot-deliver.log auth_socket_path = /var/run/dovecot/auth-master postmaster_address = postmaster(a)leetcode.net mail_plugins = cmusieve sieve_global_path = /srv/mail/sieverc plugin { sieve = /srv/mail/%u/sieverc } } ### end dovecot.conf ### dovecot.log deliver(jreese(a)leetcode.net): Jan 24 14:30:40 Info: Loading modules from directory: /usr/lib/dovecot/modules/lda deliver(jreese(a)leetcode.net): Jan 24 14:30:40 Info: Module loaded: /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.so deliver(jreese(a)leetcode.net): Jan 24 14:30:40 Info: auth input: jreese(a)leetcode.net deliver(jreese(a)leetcode.net): Jan 24 14:30:40 Info: auth input: maildir=jreese(a)leetcode.net/ deliver(jreese(a)leetcode.net): Jan 24 14:30:40 Info: auth input: uid=900 deliver(jreese(a)leetcode.net): Jan 24 14:30:40 Info: auth input: gid=900 deliver(jreese(a)leetcode.net): Jan 24 14:30:40 Info: maildir: data=/srv/mail/jreese(a)leetcode.net/Maildir deliver(jreese(a)leetcode.net): Jan 24 14:30:40 Info: maildir++: root=/srv/mail/jreese(a)leetcode.net/Maildir, index=, cont> deliver(jreese(a)leetcode.net): Jan 24 14:30:40 Info: cmusieve: /srv/mail/%u/sieverc doesn't exist deliver(jreese(a)leetcode.net): Jan 24 14:30:40 Info: cmusieve: Using sieve path: /srv/mail/sieverc deliver(jreese(a)leetcode.net): Jan 24 14:30:40 Info: cmusieve: Executing script /srv/mail/sievercc ### end dovecot.log -- John Reese LeetCode.net

[Dovecot] v1.1.9 released
by Timo Sirainen 23 Jan '09

23 Jan '09

http://dovecot.org/releases/1.1/dovecot-1.1.9.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.9.tar.gz.sig Lots of small dbox fixes, hopefully migrations from Maildir are now working correctly. I'm also planning on releasing v1.2.beta1 in a few days. + Sending SIGUSR2 to dovecot-auth now also logs statistics about cache inserts. This could help figuring out auth cache size. + deliver: Added rejection_subject setting, which is used for rejected mails. + pop3: Prevent clients from looping forever trying to fetch an expunged message. + If login process crashes, log the IP address that (maybe) caused it. + If core dump limit is 0, add "core dumps disabled" to startup log line. + Log better messages for "Permission denied" errors - mbox: Fixed assert-crash with pop3_lock_session=yes - dbox: Fixes to handling maildir-converted files. - Auth cache wasn't working correctly for all fields (e.g. allow_nets) with blocking passdbs (e.g. mysql). - pgsql: Handle reconnecting to server without failing auth lookups. - Berkeley DB memory/resource leak fixes. - maildir: Fixes to handling over 26 keywords.
