[Dovecot] Released Sieve v0.1.1 and ManageSieve v0.11.2 for Dovecot v1.2.alpha4
by Stephan Bosch 25 Nov '08

25 Nov '08

Hello Dovecot users, Since the first release of the new Sieve implementation, not that many bugs were reported. This is probably due to the fact that it is not tried yet by that many people. In the mean time, I did find and fix some more bugs myself, I adapted to changes in Dovecot, wrote some more documentation and started work on the enotify extension. Both Sieve and ManageSieve were changed to match API changes in Dovecot and therefore older versions will not compile against the new Dovecot release. Likewise, these new Sieve and ManageSieve releases will not compile for older Dovecot versions. Changelog Sieve v0.1.1: * Re-enabled support for compiling against dovecot headers. Much like cmusieve, command line tools like sievec and sieved are not compiled in this case. * Started implementation of enotify extension. Not anywhere near finished though. * Adapted to changes in Dovecot on various occasions, making this release dependent on Dovecot >= v1.2.alpa4. + Improved logging of errors at specific occasions and added debug messages to find script execution problems quicker. + Removed code duplication between command line tools and the test suite. Also restructured the sources of the tools. + Added UTF-8 to UTF-7 folder name conversion for compatibility with IMAP. + Created man pages for the command line tools. These are automatically installed upon 'make install' + Incorporated Valgrind support into the test suite and fixed a few memory leaks in the process. - Fixed compile error surfacing for gcc3.4. Forgot mask argument for the open() system call when the O_CREAT flag is specified. Bug found by Sergey Ivanov. - Fixed bug in the sievec tool. -d output was always written to stdout. - Fixed important bug in the imap4flags extension. When no :flags argument is specified, the previous version would always use the final value of the internal variable to set the flags. This means that modifications to the internal variable also affected the bare fileinto/keep actions executed earlier. This does not comply to the RFC. - Fixed bug in the include extension's import/export commands. Duplicate import/exports caused problems. - Fixed bug in the handling of non-existent scripts. Errors were sometimes ignored. - Dovecot omitted unfolding multi-line headers. This was added to the cmusieve plugin after the code was incorporated into the new implementation. This is now implicitly fixed by concurrent change in Dovecot. Changelog ManageSieve v0.11.2: * Adapted to changes in Dovecot, making this release dependent on Dovecot >= v1.2.alpa4 The following files are released: Sieve: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.1.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.1.tar.gz.sig ManageSieve package: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.2.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.2.tar.gz.s… ManageSieve patch: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.alpha4-managesieve-0.11.2.d… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.alpha4-managesieve-0.11.2.d… The full story of the new Sieve implementation is available in my previous posting: http://www.dovecot.org/list/dovecot-news/2008-October/000087.html I still need to update the wiki with pointers to the new Sieve implementation. I hope to have some time and motivation to do so in the next few days. Have fun testing the new releases and don't hesitate to notify me when there are problems.

[Dovecot] v1.1.7 released
by Timo Sirainen 25 Nov '08

25 Nov '08

http://dovecot.org/releases/1.1/dovecot-1.1.7.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.7.tar.gz.sig I should have released this earlier since v1.1.6 had that annoying startup problem, but surprisingly few people complained about it so I kind of forgot about it then. BTW. v1.2 progresses nicely. Now that shared mailboxes are finally fully supported, there aren't any widely used IMAP features missing from Dovecot. v1.2.beta1 shouldn't be in too distant future anymore. * IMAP QUOTA extension now returns "MESSAGE" quota, not "MESSAGES". This makes Dovecot now RFC 2087 compliant. Hopefully this change doesn't break anyone's Dovecot-specific quota checking code.. + Added !include and !include_try directives to config file reader. Note that !include doesn't currently work with deliver. The main point here is that ssl_key_password can be placed to a different file with !include_try that deliver can just ignore. + More error/debug message logging improvements. - v1.1.6 gave "userdb didn't return a home directory" error at startup - Some config file parsers (deliver, passwd-file, acl, trash) ignored the file's last line if it didn't end with LF. - fts: SEARCH SUBJECT didn't search messages that weren't already in fts index. - fts-solr: Don't assert-crash if we couldn't connect to Solr. - IMAP: Mailbox deletion gave an error, but still worked, if mails' control directory wasn't the same as index directory. - Several fixes to rarely used mailbox list layout configurations.

[Dovecot] PLAIN password scheme question
by Dmitri V. Ivanov 24 Nov '08

24 Nov '08

Hi, ppls There is some problem with using passwd-like file and plaintext passwords within it. Let's assume we have users speaking russian. They think and remember their passwords also within russian words (they just not change keyboard layout before entering their passwords). So if the user has password like ":jgf" (meaning "ass" in russian) and passwords are stored into passwd-like file within {PLAIN} scheme what will happen? ===== user:{PLAIN}:jgf:1234:1234:.... ===== Isn't it a reason to implement something like {HEX} and why?

But why do you think there's a bug in Dovecot? Note > that Dovecot never even sees this value. It's the kernel that enforces > it, Dovecot simply reacts to a write() failure. The logs stating the "File too large" errors belong to dovecot's deliver process. While I was searching for a solution, I read that deliver honors mailbox_size_limit setting of postfix, I'm not sure if that is correct or not. Note that the destination mailboxes are smaller than 2GB here, but still gets "File too large" error. The machine is 64-bit, so no fs related kernel limits on file size. I have not dived into postfix and/or dovecot internals, but my guess is , dovecot gets the mailbox size limit and behaves accordingly. If that is the case, the problem can be fixed in dovecot's deliver code. If postfix sets file size limit with ulimit before execing deliver, OR uses a similar process which is out of deliver's control, then there is nothing concerning dovecot. If someone can clarify the issue I would be happy. -- Gokdeniz Karadag

[Dovecot] pam auth fail considered mail.error?
by David Halik 24 Nov '08

24 Nov '08

Hello all, Following the Dovecot wiki and migration help, we recently migrated our core IMAP systems from Courier to Dovecot on Solaris. So far it's been working great, but I have one issue that I'm curious about. Just as the docs mention, we also use "syslog_facility = mail" for logging. Unlike in the past, failed PAM auth attempts are now getting logged as mail.error: Nov 24 08:34:34 xxx.xxx.xxx.xxx dovecot: [ID 107833 mail.error] auth-worker(default): pam(dhalik,xxx.xxx.xxx.xxx): pam_authenticate() failed: Authentication failed Is there a reason for this, or a way to configure this behavior? mail.error is a little harsh for pam auth failures and I would think that the auth channel would be used instead similar to other processes (sshd, courier, etc) I'd like to continue using the mail facility, but if every time there is an auth error Dovecot reports to mail.error, my consoles and legitimate error logs are going to be full of something considered a non-issue by most. Any help is appreciated, thanks. -Dave -- ================================ David Halik System Administrator OIT-CSS Rutgers University dhalik(a)jla.rutgers.edu ================================

[Dovecot] two dovecot server using the same file system
by Osvaldo Alvarez Pozo 24 Nov '08

24 Nov '08

Hi all. I want to use two servers with dovecot using a common file system with drbd. So I have several questions. If one server write a mail to th file system he will use his name as part of the mail identification. the second server will use his own name. Each server will generate it own mail numbers . When an imap or pop user will consult the mails i shoul be confusion. Am I correct. is there a way of solving this issue?? Thanks

Hi, Setting mailbox_size_limit to 0 made deliveries possible. a limit of 2000000000 (<2GB) also did not show the errors. Thank you ! :) My issue is fixed but deliver might have a bug, so I will explain things, sorry for not being clear previously. Old mail server was 32 bit(an old version of debian) and used procmail for deliveries, that setup worked with the given limit of 5GB and mailbox sizes above 1GB. After migrating to an 64 bit server (debian etch) and dovecot's deliver, the stated delivery errors appeared for mailboxes above 1 GB. As I stated at the beginning of my reply, setting mailbox_size_limit below 2GB made deliveries possible. I tried with edge values, mailbox_size_limit=2147483648 (exactly 2GB) would give the following error in postfix logs: fatal: main.cf configuration error: mailbox_size_limit is smaller than message_size_limit A limit of 2147483648 - 1 worked fine. There are two distinct bugs probably, one in postfix and one in dovecot. I guess this is result of using integer values for size limit. values greater than 2GB would wrap and cause warnings in postfix. Probably, my previous limit of 5GB would confuse things and no error was reported. (I don't know how, 5GB cannot be stored in an unsigned int, double overrun makes it within limit ? :) ) Maybe moving to "long long int" for mailbox file size is a possible solution. -- Gokdeniz Karadag

I have these in in postfix/main.cf mailbox_command = /usr/lib/dovecot/deliver mailbox_size_limit = 5120000000 The user.log file shows these (I believe if no logging is specified, deliver binary tries to log with "logger" and they go to user ?) user.log.3.gz:Nov 8 21:23:01 guvercin deliver(dummy): write() failed with mbox file /var/mail/dummy: File too large user.log.3.gz:Nov 8 21:23:01 guvercin deliver(dummy): msgid=<4915957C.8090606(a)ceng.metu.edu.tr>: save failed to INBOX user.log.3.gz:Nov 8 21:23:01 guvercin deliver(dummy): sieve runtime error: Keep: Generic Error The /var/mail/dummy file exists and is 1.9GB, so my filesystem certainly supports files >1G What may be the problem ? dovecot -n output follows : ---------------------------------------- log_timestamp: %Y-%m-%d %H:%M:%S syslog_facility: local1 protocols: imaps pop3s ssl_cert_file(default): /etc/ssl/certs/imap-cert.pem ssl_cert_file(imap): /etc/ssl/certs/imap-cert.pem ssl_cert_file(pop3): /etc/ssl/certs/pop-cert.pem ssl_key_file(default): /etc/ssl/private/imap-key.pem ssl_key_file(imap): /etc/ssl/private/imap-key.pem ssl_key_file(pop3): /etc/ssl/private/pop-key.pem 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 mail_privileged_group: mail mail_location: mbox:~/mail:INBOX=/var/mail/%u:INDEX=/var/spool/dovecot/indexes/%u mbox_read_locks: fcntl dotlock mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 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 tb-extra-mailbox-sep imap_client_workarounds(imap): outlook-idle tb-extra-mailbox-sep imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xv%08Xu pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master:

[Dovecot] OT: Run Sieve On A Mailbox Manually
by Neil 22 Nov '08

22 Nov '08

(Apologies for being offtopic.) The subject basically says it all...does anyone know of a tool to run a sieve script on a mailbox (in particular, Maildirs) manually? Ideally, I'd like to do it without adding a bunch of new headers to the mail. So, could I just do a find (or for-loop, if it was just one maildir) command and pipe all the mails into deliver..? Thanks, Neil.

[Dovecot] mail_privileged_group not working for dotlock files (1.1.6)

Hello, Running dovecot 1.1.6 on centOS 5 and RHEL 5. With the settings: pop3_lock_session = yes mail_privileged_group = mail mail_location = mbox:~/:INBOX=/var/spool/mail/%u mbox_read_locks = fcntl mbox_write_locks = dotlock fcntl and /var/spool/mail permissions: drwxrwx--x 2 root mail 4096 Nov 19 10:16 mail/ Trying to connect via POP3 results in this error: --- Nov 19 09:31:01 lexiconn2 dovecot: child 32127 (pop3) killed with signal 11 Nov 19 09:31:01 lexiconn2 dovecot: POP3(cerberus): file_lock_dotlock() failed with mbox file /var/spool/mail/xxx: Permission denied Nov 19 09:31:01 lexiconn2 dovecot: pop3-login: Login: user=<xxx>, method=PLAIN, rip=1.2.3.4, lip=5.6.7.8, secured --- The docs seem to indicate the above config / settings should work. Is this a bug? The reason we have dotlock as the primary format is due to procmail LDA from sendmail: --- procmail -v 2>&1|grep Locking Locking strategies: dotlocking, fcntl() --- I assume we have to make the "mbox_write_locks" match the procmail locking... Thanks. Rob

[Dovecot] expire-tool fails if mail_location contains %h
by Thorsten Vollmer 21 Nov '08

21 Nov '08

Hi Timo, not long ago you fixed a bug regarding the expansion of ~/ in mail_location that prevented expire-tool from working correctly. A similar problem exists if mail_location contains %h: expire-tool will use the wrong path to access the mailbox. After replacing %h with ~, expire-tool works as expected. Why are there two variables for the home directory? Maybe the use of %h could be discouraged, sparing you some problems. Regards, Thorsten

[Dovecot] Separate quotas not displayed correctly
by Laurent Blume 21 Nov '08

21 Nov '08

Hello all, My system is set up to have quotas both on /var/mail, where emails are received, and on /export/home, where users' homedirs are. But the client (Thunderbird) shows the same /export/home values both for the Inbox and for the folders in the homedir, so a user cannot know where she stands on her /var/mail use. This is Dovecot 1.1.5. As per the wiki, the dovecot.conf file contains this: quota = fs:INBOX:mount=/var/mail quota2 = fs:Others:mount=/export/home A sample user: # quota -v testimap Disk quotas for testimap (uid 1143): Filesystem usage quota limit timeleft files quota limit timeleft /export/home 6490 10000 15000 0 0 0 /var/mail 0 20000 25000 0 0 0 When Icheck the Quota tab in the Properties of the Inbox, the field contains "Others", and the value are 6490 out of 10000. Any idea why this doesn't display the value of /var/mail?

[Dovecot] Dovecot and Bogofilter
by Matthias-Christian Ott 21 Nov '08

21 Nov '08

Hi, on my small Xen-virtualised server with 48 MiB RAM I use Postfix and Dovecot, because the Debian administrators dislike qmail [1], which is in my opinion despite some maintainability and code quality issues a quite well designed software, because it mostly follows the UNIX principles. Postfix is not able to sort my E-Mail into different Maildir folders and after I looked at procmail's source code, I decided to use Dovecot's LDA, because it supports sieve via a plugin. All in all it worked after some tweaking and Dovecot is now responsible for authentication and delivery. Furthermore I want to setup a spam filter and due to the memory constraints I decided in favour of bogofilter (I made no real world tests, but the authors claim that it's fast and has a small memory footprint). My first idea was train bogofilter via a cronjob that runs bogofilter for each E-Mail in my spam folder and deletes them afterwards. Then I stumbled upon the dovecot antispam [2] plugin and quickly wrote a backend for bogofilter. During the development I realised that bogofilter has to update the X-Bogosity header of the reclassified E-Mails. Johannes Berg told me that he wasn't sure whether dovecot would be able to do this and recommended to ask this on the mailing list. An other problem is that each mail needs to be initially classified and due to the fact that sieve is not able to execute external programmes, deliver has to do this task. I'm currently thinking of possibilities to implement this, so far I came up with the following: 1. Write a generic pipe plugin which can execute an arbitrary number of programmes. The problem with this is that I'm not sure how to integrate this is in Dovecot's configuration file. I thought of something like this: pipe = prg1 | prg2 2. Write a bogofilter-specific plugin for this. Anyhow I would like to take this opportunity to criticise Dovecot for being a bloated (unnecessary abstractions, verbose, pseudo object-oriented, ...), non-suckless [3] and non-unixish (plugin architecture, monolithic design, ...) software which in return works quite well and stable so far. I appreciate any suggestions, ideas or criticism. I would really like to finish configuring my mail server as soon as possible. Regards, Matthias-Christian [1] http://smarden.org/pape/Debian/1215531259.4854_332.werc [2] http://johannes.sipsolutions.net/Projects/dovecot-antispam [3] http://www.suckless.org/common/

[Dovecot] nfs_flush_fcntl failed: No locks available

Dear dovecot list: Could any experts help me on the configuration of per-user for dovecot on FreeBSD 7.x with postfix-2.5.4,1. I followed the howto of http://workaround.org/articles/ispmail-etch/, it is an excellent file, my mailserver worked very well. When I configured per-user quota plug-in, quota_rule with 20MB limits can not be overrided by the Mysql query statement, Although I followed the document at : http://wiki.dovecot.org/Quota. Below is the output of dovecot --version, dovecot -n and dovecot-sql.conf. Could any experts help me? Thanks in advance !

[Dovecot] Per User Quotas
by Peter Fraser 21 Nov '08

21 Nov '08

HI All Asking for a little patience and a bit of help here. I'm using dovecot-1.1.3_1 with postfix and squirrelmail. I have implemented a global quota successfully. That works fine. I want to now implement per user quotas. So far I have read the howto in the documentation and searched several threads but can't seem to get it working properly. My LDAP server is Windows 2003 Active Directory. Is there any documentation specific to AD that I could look at or any other doc that could help me? My last effort was to put this in dovecot-ldap.conf user_attrs = streetAddress=quota_rule4=*:storage=%$M ,=uid=1002,=gid=1002,=home=/home/vmail/%u and this in dovecot.conf in addition to the other quota rules. quota_rule4 = *:bytes=%$ I then put the quota in the streetAddress area of AD. I'd certainly appreciate any help. Thanks.

[Dovecot] make archive emails undeletable?

I've been using dovecot for a year or two now, and really like it. I have a fairly simple setup, but I think it's time to get a little more advanced. I keep an "archive" of all my email, both sent and received. Every once in a while I get confused, and accidentally delete something from my archive. I also worry that I'll misconfigure a mail client some day and accidentally wipe out my "trash" folder. I would like some way to prevent deletion in several mailboxes. Is that possible? It looks like ACL could do this, but I can't quite figure out where to start. Any pointers would be greatly appreciated. Thanks, Rob

[Dovecot] Auth Issues - Urgent - Help!
by David Cunningham 21 Nov '08

21 Nov '08

After a few hours of running, I get tons of the following errors in my logs: dovecot: Oct 08 07:41:50 Error: auth(default): ldap(user(a)domain,x.x.x.x): Request queue is full I removed the username and IP, obviously. Any idea how to stop this? I have about 5 Thousand users using horde that login ever 1-5 minutes to refresh their page. I assume it is a setting, but I am confused as to why it doesn't happen almost right away. It seems to take some time to build up. Please help! This is taking my webmail system down hourly.

[Dovecot] Error message in logs since 1.1.6 upgrade
by Guy 21 Nov '08

Hi, I've got two imap boxes, one is running 1.1.5 and hasn't exhibited the error below, but the one that's been upgraded to 1.1.6 is showing them.

[Dovecot] sieve-body extension support for deliver LDA's sieve plugin
by BrunoM 21 Nov '08

21 Nov '08

Hello, I just read your message about sieve and body-extension in Dovecot. Do you have news on that topic? I just have to filter mails containing a particular text fragment, and I cannot do without sieve body, I think.. Thank you for any clue you'd be able to give me ! Regards, Bruno --- Hi Timo & Co, Is there any time frame for updating the deliver LDA's sieve plugin code to that from Cyrus IMAPd v2.3.x? I ask as I'm looking for the functionality of the sieve-body extension, as described here: http://www.ietf.org/internet-drafts/draft-ietf-sieve-body-06.txt This requirement has come up as we're upgrading from a Courier-IMAP/maildrop configuration that has some filtering based on message body content. As an aside, if that time frame is undefined or will be long, if I use maildrop instead as my LDA, will I loose the instant delivery notification via IMAP IDLE? Thanks very much, Scott

[Dovecot] %d in deliver
by Mark Zealey 21 Nov '08

21 Nov '08

Hi there, I run a system that has a lot of virtual users. We invoke deliver from exim and pass the directory to deliver into using the HOME environment variable, so deliver doesn't do any database lookups during the delivery process. The exim pipe environment is described at http://exim.org/exim-html-current/doc/html/spec_html/index.html#toc0239, but basically I'd like to know the domain as well as the user, however deliver doesn't seem to pick this up. Is there any way that you could extend deliver to make it either pick up the domain (or correct username) from the command line, but not do an authdb lookup; or get it to read the domain from an environment variable (or be able to print the contents of an arbitrary environment variable in a formatted string)?

[Dovecot] namespace public / namespace shared - question
by Michal Soltys 21 Nov '08

21 Nov '08

After looking through wiki/config/list I'm still not sure, what exactly is the difference between those two. Even all the examples in dovecot's wiki don't have a single "namespace shared" anywhere. And there's only short mention about the difference in dovecot.conf . Peeking into rfc2342 - would shared namespace relate to "Other Users' Namespace(s)" and public namespace to "Shared Namespace(s)" ? Does perhaps the difference only lie on the client side, depending on the namespace it's asking, while functionally it's the same from the perspective of dovecot ?

[Dovecot] CRAM-MD5 and proxy_maybe
by David Jonas 20 Nov '08

20 Nov '08

When using proxy_maybe CRAM-MD5 authentication fails when the connection is proxied. Is this expected behavior? Is proxy_maybe too simplified for this case? We're using SQL so I could rewrite the query with IFs to fake proxy_maybe and return the password as NULL and nologin as Y, but if it works that way couldn't it work with proxy_maybe? This works: password_query = \ SELECT NULL AS password, host, CONCAT(user,'@',domain) AS destuser \ 'Y' AS nologin, 'Y' AS nodelay, 'Y' AS proxy \ FROM accounts WHERE class='pop' AND domain='%d' This doesn't work if proxied and CRAM-MD5 auth: password_query = \ SELECT \ CONCAT(user,'@',domain) AS user, password, \ host, 'Y' AS proxy_maybe, \ target AS userdb_home, uid AS userdb_uid, gid AS userdb_gid \ FROM accounts WHERE \ class='pop' AND domain='%d' AND user='%n' \ LIMIT 1 Thanks, David

I'd like to take advantage of RFC5229 match variables (it would reduce the number of rules I have by an order of magnitude); however, the required extension isn't supported yet. Am I mistaken? If not, are there plans to support it?

[Dovecot] Unbreakable NFS locking issues...
by Rod Treweek 20 Nov '08

20 Nov '08

Hello All, We are struggling to find a solution to a problem we are encountering with a load-balanced email setup. Currently, we have a Coyote loadbalancer, and 3 Postfix/Dovecot nodes that then get their information from a mysql database. The problem is that after a couple weeks, we start seeing NFS locking issues occur, which then takes email completely down, requiring a site visit to basically do an interactive mode reboot to shut off NFS so that we can remount the filesystem again. We have our mailstore on an Aberdeen NAS which is accessed over NFS v. 4. Dovecot version 1.1.2 Here's the relevant mysql string: grep -v '^ *$#.*$\?$' dovecot-mysql.conf driver = mysql connect = host=X.X.X.X dbname=Something user=Something password=Something password_query = SELECT username as user, password, concat('/NFS1MAILDIR/mailSysV2/', maildir) as userdb_home, concat('maildir:/NFS1MAILDIR/mailSysV2/', maildir) as userdb_mail, 143 as userdb_uid, 143 as userdb_gid, concat('*:bytes=', floor(quota*1024)) AS quota_rule FROM mailbox WHERE username = '%u' AND active = '1' user_query = SELECT concat('/NFS1MAILDIR/mailSysV2/', maildir) as home, concat('maildir:/NFS1MAILDIR/mailSysV2/', maildir) as mail, concat('maildir:/NFS1MAILDIR/mailSysV2/', maildir) as maildir, 143 AS uid, 143 AS gid, concat('*:bytes=', floor(quota*1024)) AS quota_rule FROM mailbox WHERE username = '%u' AND active = '1' And here's what our configuration is on each of the nodes: dovecot -n # 1.1.2: /usr/local/etc/dovecot.conf protocols: imap pop3 ssl_ca_file: /usr/local/etc/dovecot/certs/tdpserver.crt ssl_cert_file: /usr/local/etc/dovecot/certs/tdpserver.crt ssl_key_file: /usr/local/etc/dovecot/certs/tdpserver.key ssl_parameters_regenerate: 0 ssl_cipher_list: ALL:!LOW:!SSLv2 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 login_user: postfix login_greeting: Something witty here.. login_process_per_connection: no login_max_connections: 512 max_mail_processes: 2048 mail_max_userip_connections: 50 verbose_proctitle: yes first_valid_uid: 69 last_valid_uid: 500 first_valid_gid: 69 last_valid_gid: 500 mail_access_groups: postfix mail_privileged_group: postfix mail_location: mbox:/NFS1MAILDIR/mailSysV2/%d/%u:INDEX=/usr/local/mail/indexes/%d/%1n/%n mmap_disable: yes dotlock_use_excl: no mail_nfs_storage: yes mail_nfs_index: yes 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_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota 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 netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(pop3): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: login plain user: dovecot passdb: driver: sql args: /usr/local/etc/dovecot-mysql.conf userdb: driver: sql args: /usr/local/etc/dovecot-mysql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: dovecot group: dovecot plugin: quota: dict:user::proxy::quota imap_quota: dict:user::proxy::quota quota_rule: *:storage=528576 dict: quota: mysql:/usr/local/etc/dovecot/dovecot-dict-quota.conf Any help you can offer is greatly, greatly appreciated, as well as opinions on any other 'validated' postfix/dovecot email enterprise design solutions.

[Dovecot] New message notification
by Juan Asensio Sánchez 19 Nov '08

19 Nov '08

Hi What is the best option to notify a user that a message has arrived? The intention is to write a script that connects to a jabber server and checks if the user is online, so then a message is sent to user notifying him that he has received a new message. The solution should be compatible with Sieve filtering, so the script should not be executed when the message is moved to the SPAM folder, or pass to the script an argument specifying the folder where the message has been saved. Regards and thanks in advance. Juan Asensio Sánchez - http://www.nutum.es

[Dovecot] Solving CVE-2008-4870
by Michal Hlavinka 19 Nov '08

19 Nov '08

Hi, we're trying to solve CVE-2008-4870 = rhbz#436287 = dovecot.conf is world readable - possible password exposure. This problem seems to be little more complicated than we thought. dovecot.conf can contain passphrase for ssl key, which is available for everyone since dovecot.conf has world readable permissions. (In CVE's description is note that it RHEL's/Fedora's problem, but it affects all systems imo) We was thinking about few ways how to fix it: 1) 0640 permissions for dovecot.conf - but it can became not readable for dovecot 2) 0640 root:mail and set deliver to group mail with sgid - possible security problem 3) don't store passphrase in dovecot.conf, just ask for it when dovecot's started - can hang boot process, not good As part of investigating, I've found dovecot is storing all variables in environment variables - it means even passphrase? I'm not completely sure, but all variables can be read via /proc/<pid>/environ (I don't know if it becomes readable in some circumstances.) Is there any plan to solve this problem? Cheers, Michal

[Dovecot] patch: list shared namespace
by Bernhard Herzog 19 Nov '08

19 Nov '08

Hi, I've been working on a patch for dovecot 1.2 from the Kolab branch (http://hg.intevation.org/kolab/dovecot-1.2_kolab-branch/) that implements listing of shared namespaces. I've got something that works in some basic way but is still missing some pieces. See the attached patch, which also contains some installation and configuration notes. Implementation notes: One of the main problems the patch addresses is getting a list of all users that have mailboxes the logged in user can see. The patch uses a dict to cache information about which users have at least one mailbox that is visible to other users. The dict doesn't cache which other users, though. The cache entry for a given user is updated whenever the dovecot-acl-list file in the maildir root directory is updated. This ties the implementation to a specific acl backend to an extent, but that shouldn't be a problem at the moment. Another problem is that namespaces for all those users have to be created. The patch does that in shared-storage.c when the shared storage is created. At this stage of development of the patch that works well enough, I think, but it might be better to update the namespaces whenever a list iterator is created. To avoid unnecessary coupling between the shared namespace code and the ACL plugin, the shared namespace code has a hook that it calls when it needs a list of all the users who may have mailboxes visible to the current user. The ACL plugin sets that hook and uses the dict to produce that list. This way, the ACL plugin depends on the shared namespace code but not the other way round and all the dict handling is in the ACL plugin. I'm not sure the new hook is really needed. The patch could perhaps just as well extend the acl_next_hook_mail_storage_created and acl_next_hook_mailbox_list_created functions to do the namespace creation when they're called for a shared storage or mailbox list. Problems: All of my tests so far involved a shared namespace of the form namespace shared { separator = / prefix = users/%%u/ location = maildir:.../var/mail/%%u:... subscriptions = no list = yes hidden = no } Also, let's assume two users, ford and arthur with ford's "INBOX/hhgttg" available to arthur as "users/ford/INBOX/hhgttg". Arthur may not list ford's INBOX, though. In the following the current user is always arthur. I found the following problems: - LIST response includes namespaces the user doesn't really have access to. E.g. if there's another user, zaphod who's made some mailbox available to somebody else, but not arthur, arthur still sees * LIST (\Noselect \HasChildren) "/" "users/zaphod" Not sure it's worth fixing this, though. - List with "%" doesn't list all intermediate mailboxes. On the one hand arthur sees this: x LIST "" "*" ... * LIST (\Noselect \HasChildren) "/" "users/ford" * LIST (\HasNoChildren) "/" "users/ford/INBOX/hhgttg" x OK List completed. OTOH, with "%" only this: x LIST "" "users/ford/%" x OK List completed. cyrus shows x LIST "" "users/ford/%" * LIST (\Noselect \HasChildren) "/" "users/ford/INBOX" x OK List completed. At least Kontact resp. KMail rely on this. - The dovecot-acl-list is not always rebuilt, even when it should have been, AFAICT. In particular, if the file exists but is empty, it's never updated, even when ACL later change. Maybe this is a bug in the Kolab branch.

[Dovecot] Bug in 1.1.4: New line required in ACL files

Hello, just wanted to notify you about a bug i found in 1.1.4 ACL handling: Global ACLs are ignored, when there is no line break (i.e. "owner lr" is ignored while "owner lr\n" works). I didn't track this down to see if the same happens for per-user ACLs, but it should be quite obvious in the source anyways.

Client: Mail.app v.3.5 Server: Dovecot 1.1.6 I've noticed that when I go to "Account Info" in Mail.app, and then to the "Subscription List" tab, Mail.app will spin for a bit, and then give up, without showing any folders and all the buttons are grayed out. Does anyone know if this a Mail.app issue or a Dovecot issue, if there're any work-arounds, and/or if this is something I should be concerned about? Thanks, Neil.

[Dovecot] Password authentication and character set

[Dovecot] MESSAGE Quota not RFC2087 compliant
by Braun, Martin 18 Nov '08

18 Nov '08

Hi, the configuration of my Dovecot 1.1.3 quota plugin looks like this: quota_rule = *:storage=1G quota_rule2 = *:messages=1337 this leads to the following GETQUOTAROOT response: 01 GETQUOTAROOT INBOX * QUOTAROOT "INBOX" "mbraun quota" * QUOTA "mbraun quota" (STORAGE 6553 1048576 MESSAGES 122 1337) 01 OK Getquotaroot completed. RFC2087 (http://www.faqs.org/rfcs/rfc2087.html) describes the response like as: STORAGE: Sum of messages' RFC822.SIZE, in units of 1024 octets MESSAGE: Number of messages As you can see, the response "MESSAGES" differs from the specified "MESSAGE" which leads to parsing issues on RFC compliant IMAP client implementations. Using *:message=1337 throws a configuration error on Dovecot startup. dovecot-1.1.6/src/plugins/quota/quota.h /* Number of messages. */ #define QUOTA_NAME_MESSAGES "MESSAGES" Greetings, Martin

[Dovecot] ManageSieve SECURITY hole: virtual users can edit scripts of other virtual users (all versions)
by Stephan Bosch 17 Nov '08

17 Nov '08

Hello, While updating the ManageSieve implementation to the latest draft specification I noticed a major omission in the way script names are handled. Essentially, script names are directly appended to the sieve storage directory path and suffixed with '.sieve'. This does not take the use of '../' in script names into account. Therefore, clever virtual users that know the directory structure of the server can read and edit script files of other virtual users with the same system uid. The added '.sieve' suffix prevents further security breach, because only sieve scripts are accessible this way. Note that of course any publicly accessible sieve script is also affected. I am sorry to report that this bug was introduced pretty much from the start, meaning that all versions of the ManageSieve patch/package are affected. To quickly resolve this issue, I provide patches against the existing releases and I release new versions for Dovecot v1.1 through v1.2. The security patches against the existing releases are very small and should therefore also apply to older versions or can be adjusted to apply cleanly with relative ease. The security patches are available as follows: http://www.rename-it.nl/dovecot/1.0/dovecot-1.0.15-managesieve-v9.3-securit… http://www.rename-it.nl/dovecot/1.0/dovecot-1.0.15-managesieve-v9.3-securit… http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.3-security… http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.3-security… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.0-security… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.0-security… The security patch for v1.0 is applied against the patched Dovecot tree, while patches for v1.1 and v1.2 are applied against the ManageSieve package. The new releases are available as follows (v1.1 and v1.2 versions have additional changes, read the NEWS files for more info): http://www.rename-it.nl/dovecot/1.0/dovecot-1.0.15-MANAGESIEVE-v9.4.diff.gz http://www.rename-it.nl/dovecot/1.0/dovecot-1.0.15-MANAGESIEVE-v9.4.diff.gz… http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.4.tar.gz http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.4.tar.gz.s… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.1.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.1.tar.gz.s… Refreshed ManageSieve patches for v1.1 and v1.2 are available to avoid confusion, but an existing patched Dovecot should work fine. I hope package maintainers will quickly incorporate the security patches to get rid of this stupidity as soon as possible. Don't hesitate to notify me when there are problems!

[Dovecot] Dovecot error with Symbian mail client
by jeeger＠thenybble.de 17 Nov '08

17 Nov '08

Greetings list, I have recently acquired an Nokia E71 (which comes with Symbian 3rd edition, feature pack 3 I believe). Accessing my emails has worked before, but now, I cannot connect to the mail server any longer. If I enable verbose_ssl, I get the following error in the log: SSL_accept() failed: error:140943F2:SSL routines:SSL3_READ_BYTES:sslv3 alert unexpected message [141.84.69.67] I cannot access my mail, the dialog just closes and the wireless connection ends. I am using dovecot version 1.0.13 and my config is # 1.0.13: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps ssl_cert_file: /etc/dovecot/dovecot.crt ssl_key_file: /etc/dovecot/dovecot.pem verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login auth default: passdb: driver: pam userdb: driver: passwd Thanks for your answers! Regards, Jan Seeger PS: I have tested the symbian client with gmail, and it works. So the problem is probably a bug in the communication between the symbian client and dovecot.

17 Nov '08

Hi, I am using dovecot 1.0.10 and pysieved, in a master/slave cluster with ldap (auth_bind=yes). For conceptuals reasons, i would like to keep on the same partition the mailstore + sieve scripts. I have try to set "sieve" and "home" variables under the "plugin" section with an absolute path, and i have tried to override home variable in user_attrs (dovecot-ldap.conf) as well with an absolute path, but in vain. Is there a solution ? sam

[Dovecot] OT: Counting emails in IMAP folders
by Nigel Allen 17 Nov '08

17 Nov '08

Greetings I have a customer who has mail server running dovecot with an IMAP account (Customers) which contains hundreds of folders (one per customer). Looks like this: Customers Fred Smith and Co Joe Blogss Cust-1 Cust-n They have a requirement to report monthly on the total number of emails added to each customers' folder during the month. Basically I need to be able to run some kind of command line query that will give me each of the sub-folder names and the number of emails added to the folder for that month (or other user-specified time period). Any ideas please? TIA Nigel.

[Dovecot] Mailbox Hashing
by Justin Krejci 14 Nov '08

14 Nov '08

First off, the website documentation is really good for Dovecot but while reading I was not able to find anything pertaining to inbox hashing for Maildirs. I saw plenty about hashing the directories that the user mailboxes live in but nothing about specifically hashing an individual user's inbox directory itself. Is there any method for hashing the inbox automatically after say 5,000 messages are stored? Example $Maildir/in/0/message0 $Maildir/in/0/message1 $Maildir/in/0/message2 . $Maildir/in/0/message4999 $Maildir/in/1/message5000 $Maildir/in/1/message5001 etc I am not currently using Dovecot but am interested to know if this is available or does running with 20,000+ messages in a single inbox not affect the performance much? I have looked into other file system tuning techniques such as enabling ext3 dir_index or using ReiserFS (maybe not ReiserFS anymore). There will likely be 15,000 to 20,000 accounts spread out on one or more servers using a 6-drive RAID10 setup. Most accounts are not expected to have high message quantities but there will be lots of concurrent connections via pop and imap (and webmail imap). Any suggestions or feedback would be appreciated.

[Dovecot] Folder aliases
by Daniel L. Miller 14 Nov '08

14 Nov '08

I don't if this has been discussed before - or already implemented - but it would be great if I could define one or more "aliases" for a folder. A particular example might be "Sent" where different (badly-written) clients might have hard-coded "Sent" folder locations like "Sent", "Sent Items", "Sent Mail", "Mail Delivered", etc. - and I'd love to get those consolidated. It would also be nice to show a different set of folders based on the client - or if that's not possible (if the client doesn't identify itself as part of the login sequence) then somehow via login name - maybe by an extension? So where my usual login might be "user(a)domain.com", and that would continue to be supported as the default login, I could now have "user(a)domain.com+thunderbird", "user(a)domain.com+mobile", etc.? -- Daniel

[Dovecot] New Dovecot server buildout review
by David Jonas 13 Nov '08

13 Nov '08

Hello Everyone, I have the opportunity to do a new mail system build out for about 20k email boxes over a few hundred domains. I already run a system like this, but this time I can do it right :). My thought on storage is to have a 12 drive JBOD system attached via SAS to a 3ware 9690SA raid controller. Drives would be RAID'd (10 or 5) to appear as one for message storage. Dovecot would run on that box and deliver directly from postfix. POP and IMAP connections would come in directly (no proxy). Postfix head boxes in front of this do anti-virus and spamassassin, so this box won't be doing any heavy crunching, just delivery and serving of messages. Does this sound reasonable? Is there details that I'm missing? An obvious bottleneck I'm overlooking? Is anyone running a similar config with success? It all sounds very standard, but I haven't run something like this before. Thanks for the help! David

[Dovecot] Moving mail between folders
by Ilo Lorusso 13 Nov '08

13 Nov '08

Hi, Ive just installed Dovecot and postfix and Ive created a whole bunch of folders and started moving my mail around. Ive noticed that it copies the mail to the folder I wish to move the mail to and leave the original message waiting to be purged in the original folder Is there a way to have dovecot delete it straight after it has been moved? as I don't think users are going to take well to this change? any help would be appreciated Thanks, Ilo.

[Dovecot] dovecot pop3 performance, what size installation
by Brandon Lamb 13 Nov '08

13 Nov '08

Hello, I was wondering if anyone could tell me their results and maybe help me get an idea how big our mail system installation and usage is. For dovecot pop3 and nfs backend, I am curious how many machines I should expect to need. Here are my stats for what I can tell. 5-7 connections per second average, 8-12 connections per second peak. 30-50 constant connections between 3 servers (8-20+) on each server. We are servicing about 14,000+ email accounts. These are just the pop3 login stats, a lot of users use both or imap through our webmail. My question I guess is whether this is on the small side, medium or larger side mail setup, and should I be thinking that only 1 or 2 servers should be able to handle the load. Right now I am splitting it between 3. Should a single quad core box be able to handle this? Not sure if this is a simple question or not. Im not including my dovecot -n just because this is more of a generic question.

[Dovecot] removing uid, index and cache files
by Lars Uhlmann 13 Nov '08

13 Nov '08

Since a couple of days we're facing a problem with dovecot/MUA and multiple appeareances of single mails. The mail is physical existant only once but outlook shows it twice or more times. Then after some minutes these multiple "virtual" mails just disappear. Because this happens with different MUAs (Outlook and Thunderbid) I assume dovecot causes the problem. All mail are received by »getmail« from outside via POP3 and delivered to the users local Maildir. This was working without problems for over a year now. Is it save to remove to following files (will dovecot rebuild them) from every users Maildir? dovecot.index dovecot.index.cache dovecot.index.log dovecot.index.log.2 dovecot-uidlist Thahks in advance, Lars

[Dovecot] Sieve authentication / directory issue after upgrade to 1.0.13.
by Drew Calcott 12 Nov '08

12 Nov '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi everyone, I have come across a problem after upgrading from 1.0.rc17 to 1.0.13 (debian builds 1.0.13 is from etch-backports). I initially upgraded as 1.0.rc17 isn't compiled with regex support, so vacation messages that were uploaded via horde were being rejected. (Everything else was working fine, just messages that required regex functions were failing). Horde is uploading the filters via pysieved, which is then in turn placing them in the directory of: - --------- /shared/spool/active/%d/%0.1u/%1.1u/%n/sieve/ingo - --------- At least, it was previously. Since upgrading, dovecot has changed the way it passes authentication details to pysieved and the domain is no longer included in the username, so the domain cannot be parsed and pysieved fails as it is unable to strip a value for %d. (as a quick aside, this isn't an issue with single domain servers as there is a "defaultdomain" option that will force the value for %d, however, since we have 9 domains to deal with, this isn't going to cut it). Prior to upgrade, authentication was passed as thus (= are a new line in case the formatting dies) - -------- ======= > 'AUTH\t1\tPLAIN\tservice=pysieved\tresp=YWNhbD* restofstring * ====== < OK\t1\tuser=acal030(a)sit.auckland.ac.nz\tuser=acal030\t\n' ===== Finished SASL authentication : {'username':'acal030(a)sit.auckland.ac.nz', 'result': 'OK'} ===== Plugin returned home :'/shared/spool/active/sit.auckland.ac.nz/a/c/acal030/' = Authenticated user acal030(a)sit.auckland.ac.nz - -------- Both user and user@domain were being passed and it was a matter of simple nagging of the pysieved guys to update their code to strip the required information. However, the new version is passing auth like this: - -------- ======= > 'AUTH\t1\tPLAIN\tservice=pysieved\tresp=YWNhbD* restofstring * ======= < 'OK\t1\tuser=acal030\n' ===== Finished SASL authentication : {'username': 'acal030', 'result': 'OK'} ===== Plugin returned home : '/shared/spool/active//a/c/acal030/' - ------- The only change to the dovecot config I have made is to add "allow_all_users=yes" to userdb static as the new version was a lot stricter about the passdb pam lookup not containing the user data (and failing completely as a result). In the dovecot logs themselves, the following lines were from the earlier build: - ------ Info: auth(default): client out: OK 1 user=acal030(a)sit.auckland.ac.nz user=acal030 Info: auth(default): master in: REQUEST 243 23994 1 Info: auth(default): master out: USER 243 acal030(a)sit.auckland.ac.nz home=/blah, mail=/blah etc. - ------ Compared to this from the new one: - ------ Info: auth(default): auth(acal030(a)sit.auckland.ac.nz,130.216.39.182): username changed acal030(a)sit.auckland.ac.nz -> acal030 Info: auth(default): client out: OK 1 user=acal030 Info: auth(default): prefetch(acal030,130.216.39.182): success Info: auth(default): master out: USER 2 acal030 home=/blah, mail=/blah etc. - ------ I am rather at the end of my tether with this, unfortunately. :( I have browsed through many wiki pages looking for a possible solution or config variable I may have missed, but I really am coming up dry. Cleaned up dovecot.conf is at: http://pastebin.com/m7f4303af Should anyone want strace logs or whatever, I'm more than happy to make with them. Thanks in advance for any assistance.

[Dovecot] Dovecot master process
by Steven F Siirila 12 Nov '08

12 Nov '08

We are running into a situation where Dovecot master is simply trying to do too much. It some situations, we are finding that there are times in which it cannot service requests. Restarting Dovecot seems to help in these situations, possibly due to the fact that it no longer has to manage its THOUSANDS of file descriptors for pipes to the many imap/proxy processes that it uses for logging. Is there a way to turn off logging through the master process (in exchange for lesser security)? If not, would it be easy to have the master process do its logging using separate threads (which would help on some modern hardware)? Finally, would it be easy to delegate the task of logging to a dedicated process? We are still running Dovecot 1.0.0 at this time, on Solaris 10 servers. -- Steven F.

[Dovecot] dovecot-antispam crm114 config
by Peter Fern 12 Nov '08

12 Nov '08

Hi list, Does anyone have a working crm114 config for dovecot-antispam? I have mailreaver running perfectly otherwise, but it doesn't seem to be called correctly from dovecot-antispam - the css files show no change. Piping a message to the command... `/usr/share/crm114/mailreaver.crm --good -u /shared/domains/domain.tld/users/pfern/.crm/` works as expected, and the logs don't indicate anything useful that I can see as to why it isn't working from dovecot.

[Dovecot] How to specify /var/spool/mail/m/i/mike
by Network Operations 11 Nov '08

11 Nov '08

I was wondering if somebody could tell me how I can tell dovecot (IMAP) to read users' mail boxes at /var/spool/mail/{1st char}/{2nd char}/username . For example: Mailbox for user 'mike' would be located at /var/spool/mail/m/i/mike 'karen' would be at /var/spool/mail/k/a/karen etc... Is this possible is version 1.1.6? Please advise. Thanks JB

Thanks for > testing! It solves the problem here as well =) Thanks for the update. Do you plan to implement 'out of band' dspam calling? BTW maybe there is no need for a separate 'queue' folder especially as we only need a message signature. I think it can be stored in some buffer array so as the dspam calls are made i.e. during idle time (or during final cleanup at the latest). Also I am attaching a couple of patches that might be useful. dspam-exec.c.patch adds debug-dumping of the dspam reply (it turned out quite useful not only for the stack corruption problem). Makefile.patch fixes the syntax to compile with gmake under FreeBSD 6.1 and also adjusts the installed plugin permissions. Best wishes Eugene

[Dovecot] NFS Unbreakable lock issues
by Rod Treweek 11 Nov '08

11 Nov '08

Hello All, We are struggling to find a solution to a problem we are encountering with a load-balanced email setup. Currently, we have a Coyote loadbalancer, and 3 Postfix/Dovecot nodes that then get their information from a mysql database. The problem is that after a couple weeks, we start seeing NFS locking issues occur, which then takes email completely down, requiring a site visit to basically do an interactive mode reboot to shut off NFS so that we can remount the filesystem again. We have our mailstore on an Aberdeen NAS which is accessed over NFS v. 4. Dovecot version 1.1.2 Here's the relevant mysql string: grep -v '^ *$#.*$\?$' dovecot-mysql.conf driver = mysql connect = host=X.X.X.X dbname=Something user=Something password=Something password_query = SELECT username as user, password, concat('/NFS1MAILDIR/mailSysV2/', maildir) as userdb_home, concat('maildir:/NFS1MAILDIR/mailSysV2/', maildir) as userdb_mail, 143 as userdb_uid, 143 as userdb_gid, concat('*:bytes=', floor(quota*1024)) AS quota_rule FROM mailbox WHERE username = '%u' AND active = '1' user_query = SELECT concat('/NFS1MAILDIR/mailSysV2/', maildir) as home, concat('maildir:/NFS1MAILDIR/mailSysV2/', maildir) as mail, concat('maildir:/NFS1MAILDIR/mailSysV2/', maildir) as maildir, 143 AS uid, 143 AS gid, concat('*:bytes=', floor(quota*1024)) AS quota_rule FROM mailbox WHERE username = '%u' AND active = '1' And here's what our configuration is on each of the nodes: dovecot -n # 1.1.2: /usr/local/etc/dovecot.conf protocols: imap pop3 ssl_ca_file: /usr/local/etc/dovecot/certs/tdpserver.crt ssl_cert_file: /usr/local/etc/dovecot/certs/tdpserver.crt ssl_key_file: /usr/local/etc/dovecot/certs/tdpserver.key ssl_parameters_regenerate: 0 ssl_cipher_list: ALL:!LOW:!SSLv2 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 login_user: postfix login_greeting: Something witty here.. login_process_per_connection: no login_max_connections: 512 max_mail_processes: 2048 mail_max_userip_connections: 50 verbose_proctitle: yes first_valid_uid: 69 last_valid_uid: 500 first_valid_gid: 69 last_valid_gid: 500 mail_access_groups: postfix mail_privileged_group: postfix mail_location: mbox:/NFS1MAILDIR/mailSysV2/%d/%u:INDEX=/usr/local/mail/indexes/%d/%1n/%n mmap_disable: yes dotlock_use_excl: no mail_nfs_storage: yes mail_nfs_index: yes 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_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota 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 netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(pop3): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: login plain user: dovecot passdb: driver: sql args: /usr/local/etc/dovecot-mysql.conf userdb: driver: sql args: /usr/local/etc/dovecot-mysql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: dovecot group: dovecot plugin: quota: dict:user::proxy::quota imap_quota: dict:user::proxy::quota quota_rule: *:storage=528576 dict: quota: mysql:/usr/local/etc/dovecot/dovecot-dict-quota.conf Any help you can offer is greatly appreciated, as well as opinions on any other 'validated' postfix/dovecot email enterprise design solutions.

[Dovecot] First release (v0.1.0) of the new Sieve implementation for Dovecot v1.2
by Stephan Bosch 11 Nov '08

11 Nov '08

Hello Dovecot users, Finally, after little more than a year, I finished the first release of the new Sieve implementation for Dovecot. The main reason for rewriting the Sieve engine is to provide more reliable script execution and to provide better error messages to users and system administrators. Also, since the Sieve language evolves quickly, with new language extensions published every year, the aim is to provide support for quickly extending the engine with new features. This implementation aims to comply to RFC8225 and it provides support for the following Sieve language extensions: * fileinto * reject * envelope * encoded-character * vacation * subaddress * relational * regex * imap4flags * copy * include * body * variables In comparison to the old CMU Sieve plugin, I added support for the very useful variables extension. However, the notify extension is notably missing. This will be implemented for next major release (0.2.x). Refer to the README file for a full list of its features: http://hg.rename-it.nl/dovecot-libsieve/raw-file/0.1.0/README Installation ------------ The source package is available as follows: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.0.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.0.tar.gz.sig Alternatively, it can be cloned from the mercurial repository: hg clone http://hg.rename-it.nl/dovecot-libsieve The compilation procedure is identical to the cmusieve plugin (http://wiki.dovecot.org/LDA/Sieve) Don't forget to execute ./autogen.sh first if you obtained the sources through mercurial. This release will not compile against Dovecot versions older than v1.2.alpha3. The configuration is very similar to the original plugin as well. The most notable difference is the name of the plugin, which is simply 'sieve' in stead of 'cmusieve'. After compilation, the Sieve engine can be verified before deployment using the included test suite. This is done by executing `make test` in the top of the source tree. The test suite is known to finish flawlessly on the i386 and amd64 platforms. The test suite is not very comprehensive yet, as it only tests the evaluation of scripts and omits testing the actual execution of actions. As this release contains about 30k effective lines of fresh code, bugs will eventually surface. Make sure that you provide enough information to reproduce the problem if you report bugs, i.e. the script and the mail message that caused the problem and/or relevant log entries. Have fun testing the new Sieve plugin. Don't hesitate to notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl IRC: Freenode, #dovecot, S[r]us

[Dovecot] antispam plugin claims "antispam signature not found"
by Jakob Curdes 09 Nov '08

09 Nov '08

Hi, I am trying to setup the antispam plugin using the direct dspam backend. I have set antispam_signature = X-DSPAM-Signature in dovecot.conf and in all mails I have signature lines like X-DSPAM-Signature: 1,49084a24139132188715614 but still, if I try to move a mail into the spam folder, i get the IMAP error message "antispam signature not found". I thought it might have to do with permissions and made sure that the user running dovecot is able to execute the dspam binary. I also tried to enable debug logging to syslog (via the .config file in the make process) but I do not see any debug messages showing up; where should these go? to the mail facility? Perhaps somebody who has a working setup can shed some light on this? Yours, JC

[Dovecot] Renames across namespaces
by Ben Winslow 08 Nov '08

08 Nov '08

Will Dovecot ever support renames across namespaces? I'm attempting to support mailboxes under "INBOX" for compatibility with Courier, which I'm trying to replace, while also supporting mailboxes with no prefix. I don't want to confuse new users (who aren't already subscribed to their mailboxes with the INBOX prefix) by listing the entire tree twice (parented at the root and at INBOX.) This configuration seems to provide what I want: mail_location: maildir:~/mail namespace: type: private separator: . prefix: INBOX. inbox: yes hidden: yes namespace: type: private separator: . list: yes subscriptions: yes ...except that, when a legacy user tries to delete a mailbox under INBOX, Thunderbird (at least) renames the mailbox to make it a child of Trash at the root, e.g.: tag123 RENAME "INBOX.test" "Trash.test" tag123 NO Can't rename mailbox to another storage type. I was a little surprised that it didn't work at first, since they're both using the same (default) mail_location, but I see why it doesn't work after looking at the code. Is there any chance cross-namespace (and even cross-storage _type_) wouldn't eventually be supported? (I guess that the big problem is making cross-type renames appear atomic to clients.) Is there a better way to do what I'm trying to do? -- Ben Winslow <rain(a)bluecherry.net>

[Dovecot] Fetch order
by Warren Baker 07 Nov '08

07 Nov '08

Hi all, Is there a function to modify the fetch order of messages? We have just migrated from Courier to Dovecot and I notice that there is a slight difference in the way messages are fetched in Dovecot compared to Courier. Both Courier and Dovecot sort the mailbox correctly (UID SORT (REVERSE ARRIVAL) UTF-8 ALL), for example: [ 13:22:02.790 ]50800314 UID SORT (REVERSE ARRIVAL) UTF-8 ALL * SORT 195 194 193 192 191 190 189 188 187 186 185 184 183 182 181 180 179 178 177 176 175 174 173 172 171 170 169 168 167 166 165 164 163 162 161 160 159 158 157 156 155 154 153 152 151 150 149 148 147 146 145 144 143 142 141 140 139 138 137 136 135 134 133 132 131 130 129 128 127 126 125 124 123 122 121 120 119 118 117 116 115 114 113 112 111 110 109 108 107 106 105 104 103 102 101 100 99 98 97 96 95 94 93 92 91 90 89 88 87 86 85 84 83 82 81 80 79 78 77 76 75 74 73 72 71 70 69 68 67 66 65 64 63 62 61 60 59 58 57 56 55 54 53 52 51 50 49 48 47 46 45 43 44 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 1 4 8 10 15 18 20 25 14 19 2 3 5 9 13 17 21 22 7 11 16 6 12 23 24 50800314 OK Sort completed. But if we fetch the latest 25 messages, Dovecot will fetch the lowest UID in the list first, so from the example above it would fetch UID 171,172,173 and so on. Courier on the other hand would start the fetch on UID 195,194,193 and so on. We have an internal developed webmail application that has been affected by this change, so I am just wondering whether there is a interim fix while we fix our webmail application to cater for this. Thanks, Warren

[Dovecot] index storage usage
by Giorgenes Gelatti 07 Nov '08

07 Nov '08

Hello there, I failed in finding the answer in the wiki so i'm asking it here. In average, how much the dovecot's indexes increase the usage of storage, compared to a standard maildir mailbox? I believe it would be a function of the number of messages instead of the message's size. Is there a known aproximated function for that? Thank you. gpg

[Dovecot] (1.0.13) fsync failed: Disk quota exceeded for some accounts
by Eric Marin 07 Nov '08

07 Nov '08

Hello all, We've recently migrated the mail server used by our 5000 students, from Tru64/UW-IMAP/Procmail/Postfix/mbox to Debian Etch/Dovecot/Deliver/Postfix/Maildir E-mails are not stored directly on the server (except for index and control files), but on an NAS that exports the students' homedirs on NFS. Each student has a 100MB quota on the NAS. Here is the configuration : vega:~# dovecot -n # 1.0.13: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap pop3 listen: [::] ssl_disable: yes disable_plaintext_auth: no verbose_ssl: yes 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_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no login_process_size: 32 login_max_processes_count: 1024 mail_privileged_group: mail mail_location: maildir:~/Maildir:INDEX=/var/mail/index/%u:CONTROL=/var/mail/control/%u 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_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 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv namespace: type: private separator: / inbox: yes namespace: type: private separator: / prefix: mail/ hidden: yes auth default: cache_size: 1024 passdb: driver: pam args: blocking=yes cache_key=%u dovecot userdb: driver: passwd args: blocking=yes When one mails a student that has filled his quota, one immediately receives this message : "Your message to <studentx> was automatically rejected: Not enough disk space Reporting-UA: vega; Dovecot Mail Delivery Agent Final-Recipient: rfc822; studentx Original-Message-ID: <490F0A9A.8030109(a)utc.fr> Disposition: automatic-action/MDN-sent-automatically; deleted" And in /var/log/mail.log : (...) save failed to INBOX: Not enough disk space (...)

It gets deferred... I have looked at the changelog for Dovecot, but have not found a clear clue that is a bug (if it is !) that has already been corrected in a more recent version... Though if possible, I'd like to keep the Debian package (from etch-backports) instead of compiling it from source. Also, while I've found Dovecot's wiki to be surprisingly informative, there are still a few points that did not seem very clear : - should I use the quota:fs plugin in this case (it seems to work out well without it for most users) ? - would it work in v1.0.13 on NFS ? - if it worked, and I enabled it, what would change for me ? - what is *supposed* to happen without the quota plugin when a user has filled his quota : mail is rejected, or mail is deferred ? - and what about imap_quota ? Best regards, Eric

[Dovecot] Compiling dovecot 1.1.6 with ICC
by Steve 06 Nov '08

06 Nov '08

Hello list I have compiled PostgreSQL with ICC (Intel C/C++ compiler) and this forces me to compile dovecot 1.1.6 as well with ICC. Trying to compile it with GCC fails, telling me it can not build with PostgreSQL support since it can not find libpq (but libpq is there!). The funny part is that I can compile dovecot 1.1.6 with GCC 4.3.2 against MySQL which is build with ICC. But I can not build against PostgreSQL build with ICC. Why is that? Does any one know the reason why PostgreSQL is treated differently then MySQL in dovecot? Well... so no way to get around to build dovecote with ICC. I can build dovecot with ICC but as soon as I start it, I get a crash. Loading the core dump into GDB does not give me much info. Probably because I have not compiled dovecot with debug symbols. Currently I am doing that. Hopefully this will produce better core dumps. I will post more info as soon as I get them. But in the mean time maybe some one has a hint for me how to get dovecot 1.1.6 to build properly with ICC? // Steve -- GMX Download-Spiele: Preizsturz!

[Dovecot] Strange and sudden deletion of mails messages
by נור דאוד 06 Nov '08

06 Nov '08

Hello everyone, I'm having a bizarre problem (bug?) concerning deletion of messages from one of the mailboxes. The platform is set up as follows: FreeBSD 7-STABLE Postfix 2.6-20080411 Dovecot 1.0.13 Webmail using RoundCube 0.1-STABLE The trace (in Postfox logs) revealed that the message has been actually received, and saved to maildir, and then viewed once in Webmail. Hitting Reply in Webmail produced an error, and the letter (somehow) was nowhere to be found on the server! I have no clue what's the cause of this. Is there a way in Dovecot to catch all commands sent to the server, thus revealing who in effect deleted the message? Thanks in advance. Noor

[Dovecot] feature request for dovecot 1.2 Master users/passwords for virtual domain admins
by Robert Schetterer 06 Nov '08

06 Nov '08

Hi Timo, currently superadmins can be configured in dovecot i.e in mysql as "superadmins" this means the can log in in any mailbox on the server this is a very nice feature in real world scenarios specially for support people in postfixadmin i.e there are also defined domainadmins ( this is for delegate usermail creation/delete etc in the postfixadmingui ) in mysql it would be nice to have or simply use postfixadmins mysql domainadmins in mysql table entries to login for domainadmins only login to mailboxes of their related maildomain this would be also massiv helpfull for postmasters/support people in a full virtual setup perhaps you might get this in dovecot 1.2 before closing at beta stage -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

[Dovecot] How do I use plus-addressing in Dovecot 1.1.x?
by Jon Fullmer 06 Nov '08

06 Nov '08

I'm using Postfix, Amavisd-new/SpamAssassin, and Dovecot. They all run on the same server (running Linux). The mailboxes are stored on the same server in maildir format. The logical path for incoming messages (as I understand it) is: 1) received by Postfix; handed off to Amavisd-new 2) Amavisd-new checks to see whether or not it's spam/undesirable; hands off to Dovecot deliver 3) Dovecot deliver delivers the message to the local mailbox Under each of my user's mailbox is a submailbox called "spam". Just so I don't confuse terminologies (I'm no IMAP/maildir expert), for example, we have someone(a)domain.com. My configured mail_location is "maildir:/srv/mail/%d/%n", so this person's mailbox is located here: / srv/mail/domain.com/someone/ Within this directory is another mailbox: /srv/mail/domain.com/someone/.spam/ The plan is to have Dovecot deliver send a message (which has been labeled by Amavisd-new as spam) directly to the ".spam" submailbox, instead of the INBOX (/srv/mail/domain.com/someone/). With Dovecot 1.0.x, I used "plus addressing". Amavisd-new was configured so that, if a message was found to be spam, it delivered the message to Dovecot deliver, but changed the delivery address. Now, instead of "someone(a)domain.com ", it was "someone+spam(a)domain.com". Dovecot deliver took this message and delivered it correctly to the ".spam" submailbox (/srv/mail/ domain.com/someone/.spam/) Just to emphasize, this process does work (using Dovecot 1.0.x). With Dovecot 1.1.0, this process is broken. Now, spam messages are delivered to the INBOX instead, and, when checking the dovecot- deliver.log, I'm seeing "save failed to spam: Unknown namespace". As best as I can tell, the answer seems to lie in "namespaces" as a feature added in Dovecot 1.1.0. The problem is that I don't understand how I could use them to resolve this situation. I've read the documentation. I've looked at as many example configurations as I could find. Please help. I want to get this working again. I'm sure it's something very straight-forward, but I don't understand. How must I change my Dovecot 1.1.x configuration so that my "plus addressing" set up (detailed above) will work again? Or is there a better way? Thanks so much for your help, and thanks for a great product! - Jon

[Dovecot] Limit simultaneous pop3 login for users?
by Patrick MacDonald 05 Nov '08

05 Nov '08

Is there a way to limit simultaneous pop3 logins for users? Like for a user that has pop-every-minute running on two different computers from two different networks? If dovecot can't stop it, anyone know of a trick I could implement? Thanks in advance! Patrick

[Dovecot] mUTF-7 vs UTF-8 in mailbox names
by Timo Sirainen 05 Nov '08

05 Nov '08

(This is about v1.2 only, v1.1 will stay as it is.) Until today Dovecot didn't care about mailbox names. IMAP RFC requires them to be modified-UTF-7, but Dovecot didn't try to enforce it in any way. Mailbox names in Sieve scripts should be UTF-8, but currently Dovecot doesn't translate them to mUTF-7 as it should. Cyrus also did this until the latest release (v2.3.13). Now that I finally today wrote code to do mUTF-7 <-> UTF-8 conversion, Dovecot can finally do the right thing. But should there be an option to keep things backwards compatible? - IMAP: CREATE command requiring the mailbox name to be valid mUTF-7 is probably ok. Several other servers already verify that mailbox names are valid, so I doubt there are clients left anymore that don't send mUTF-7 names. - deliver -m assumes now that the mailbox name is UTF-8 and converts it to UTF-7. Should there be a -7 parameter that changes this behavior back? - Stephan's Dovecot Sieve also needs to be changed so that the mailbox name in fileinto commands can be UTF-8. If -7 parameter is added, it could control this behavior too. Also I'm wondering if in the future the mailbox names in filesystem should be converted to UTF-8. Probably not anytime soon though.. I also added imap_utf7 binary for doing mUTF-7 <-> UTF-8 conversion.

[Dovecot] Another dovecot-antispam plugin can't call dspam
by Rob Klingsten 05 Nov '08

05 Nov '08

Hi folks - I am configuring a new system and the antispam plugin is the last piece I need, everything else is working. Thanks to Johannes for this plugin, it's exactly what I want and an elegant solution for filter training. But I've been trying everything I can think of for the last 3 days to get this to work, no success. I've got: Postfix 2.5.3, dspam 3.8.0, Dovecot 1.1.6, Maildrop 2.0.4 and dovecot-antispam 1.0 tarball. I've built dspam from source with --disable-trusted-user-security to try and isolate the source of the plugin problem, which is the message at the IMAP client "Failed to call dspam." Here's what I've got configured for the plugin: antispam_signature = X-DSPAM-Signature antispam_trash = trash;Trash;Deleted Items;Deleted Messages antispam_spam = SPAM;Spam antispam_dspam_binary = /usr/local/bin/dspam antispam_dspam_args = --user %u And here's what happens: Nov 5 09:31:29 venus imap: antispam: plugin initialising (1.0-notgit) Nov 5 09:31:29 venus imap: antispam: "trash" is trash folder Nov 5 09:31:29 venus imap: antispam: "Trash" is trash folder Nov 5 09:31:29 venus imap: antispam: "Deleted Items" is trash folder Nov 5 09:31:29 venus imap: antispam: "Deleted Messages" is trash folder Nov 5 09:31:29 venus imap: antispam: "SPAM" is spam folder Nov 5 09:31:29 venus imap: antispam: "Spam" is spam folder Nov 5 09:31:29 venus imap: antispam: no unsure folders Nov 5 09:31:29 venus imap: antispam: dspam binary set to /usr/local/bin/dspam Nov 5 09:31:29 venus imap: antispam: dspam extra arg --user dump-capability Nov 5 09:31:29 venus imap: antispam: signature header line is "X-DSPAM-Signature" Nov 5 09:31:29 venus dovecot: Dovecot v1.1.6 starting up Nov 5 09:31:29 venus dovecot: auth-worker(default): mysql: Connected to 127.0.0.1 (postfix) Nov 5 09:31:30 venus dovecot: auth(default): new auth connection: pid=686 Nov 5 09:31:30 venus dovecot: auth(default): new auth connection: pid=687 Nov 5 09:31:30 venus dovecot: auth(default): new auth connection: pid=688 Nov 5 09:32:45 venus dovecot: auth(default): client in: AUTH 1 PLAIN service=imap lip=xxxx rip=xxxx lport=143 rport=55904 Nov 5 09:32:45 venus dovecot: auth(default): client out: CONT 1 Nov 5 09:32:45 venus dovecot: auth(default): client in: CONT<hidden> Nov 5 09:32:45 venus dovecot: auth-worker(default): sql(rob(a)xxxx.org,xxxx): query: SELECT password, email AS user FROM users WHERE email = 'rob(a)xxxx.org'; Nov 5 09:32:45 venus dovecot: auth(default): client out: OK 1 user=rob(a)xxxx.org Nov 5 09:32:45 venus dovecot: auth(default): master in: REQUEST 1 688 1 Nov 5 09:32:45 venus dovecot: auth(default): master out: USER 1 rob(a)xxxx.org uid=5000 gid=5000 home=/var/mail/xxxx.org/rob Nov 5 09:32:45 venus dovecot: imap-login: Login: user=<rob(a)xxxx.org>, method=PLAIN, rip=xxxx, lip=xxxx Nov 5 09:32:45 venus dovecot: auth(default): new auth connection: pid=688 Nov 5 09:32:45 venus dovecot: IMAP(rob(a)xxxx.org): Loading modules from directory: /usr/lib/dovecot/imap Nov 5 09:32:45 venus dovecot: IMAP(rob(a)xxxx.org): Module loaded: /usr/lib/dovecot/imap/lib90_antispam_plugin.so Nov 5 09:32:45 venus dovecot: IMAP(rob(a)xxxx.org): Effective uid=5000, gid=5000, home=/var/mail/xxxx.org/rob Nov 5 09:32:45 venus imap: antispam: plugin initialising (1.0-notgit) Nov 5 09:32:45 venus imap: antispam: "trash" is trash folder Nov 5 09:32:45 venus imap: antispam: "Trash" is trash folder Nov 5 09:32:45 venus imap: antispam: "Deleted Items" is trash folder Nov 5 09:32:45 venus imap: antispam: "Deleted Messages" is trash folder Nov 5 09:32:45 venus imap: antispam: "SPAM" is spam folder Nov 5 09:32:45 venus imap: antispam: "Spam" is spam folder Nov 5 09:32:45 venus imap: antispam: no unsure folders Nov 5 09:32:45 venus imap: antispam: dspam binary set to /usr/local/bin/dspam Nov 5 09:32:45 venus imap: antispam: dspam extra arg --user rob(a)xxxx.org Nov 5 09:32:45 venus dovecot: IMAP(rob(a)xxxx.org): maildir: data=/var/mail/xxxx.org/rob Nov 5 09:32:45 venus dovecot: IMAP(rob(a)xxxx.org): maildir++: root=/var/mail/xxxx.org/rob, index=, control=, inbox=/var/mail/xxxx.org/rob Nov 5 09:32:45 venus imap: antispam: signature header line is "X-DSPAM-Signature" Nov 5 09:32:45 venus imap: antispam: mailbox_is_unsure(Spam): 0 Nov 5 09:32:45 venus imap: antispam: mailbox_is_trash(INBOX): 0 Nov 5 09:32:45 venus imap: antispam: mailbox_is_trash(Spam): 0 Nov 5 09:32:45 venus imap: antispam: mail copy: from trash: 0, to trash: 0 Nov 5 09:32:45 venus imap: antispam: mailbox_is_spam(INBOX): 0 Nov 5 09:32:45 venus imap: antispam: mailbox_is_spam(Spam): 1 Nov 5 09:32:45 venus imap: antispam: mailbox_is_unsure(INBOX): 0 Nov 5 09:32:45 venus imap: antispam: mail copy: src spam: 0, dst spam: 1, src unsure: 0 Can anyone give me some more suggestions? thanks!

[Dovecot] MasterUser and old rev of Dovecot (0.99.14)
by Christopher Alexander 04 Nov '08

04 Nov '08

I need to migrate an old mail server running Dovecot (0.99.14) to a new server running Dovecot (1.0.7; as shipped with CentOS 5.2). My plan was to use the imapsync utility as this will "seamlessly" do the conversion from mbox to maildir between the boxes as well. I've got the MasterUser authentication working fine on the new host and was just about to start getting MasterUsers working on the old host. I noticed that the old .99 version dovecot.conf seems to have a mildly different syntax from 1.0 dovecot.conf. In particular a lot of the directives do not use braces and such. Is the .99 dovecot.conf file essentially able to deal with the same sort of syntax as outlined in the MasterUsers wiki page? [ http://wiki.dovecot.org/Authentication/MasterUsers ] I just wanted to bounce this off you guys before I started messing with a live system. ;) Thanks in advance. -- Christopher Alexander UNIX Network Administrator Broadband Network Technologies Branch (VPNT), Research Network Systems (MRNS) Communications Research Centre [ http://www.crc.ca ] Government of Canada [ http://www.gc.ca ]

It's not clear from your response that you understand why it's failing. It would seem clear that postfix doesn't see this as a local domain. Instead, it thinks you're trying to relay to somewhere else. Check your virtual_mailbox_domains file (or database) and make sure it has an entry for the new domain.

[Dovecot] v1.2.alpha1 released
by Timo Sirainen 02 Nov '08

02 Nov '08

http://dovecot.org/releases/1.2/alpha/dovecot-1.2.alpha1.tar.gz http://dovecot.org/releases/1.2/alpha/dovecot-1.2.alpha1.tar.gz.sig This is the only v1.2.alpha announcement I'm going to send to dovecot-news list. Next announcement will be for either v1.2.beta1 or v1.2.rc1. I'm hoping that v1.2 stabilizes pretty soon. There are no huge changes like there were in 0.99->1.0 or 1.0->1.1, so most of the bugs are probably related to new features. I'm already running v1.2 myself and it's gone through heavy stress testing with my imaptest tool, so I'm expecting it to be stable enough for real world testing with not-all-that-important servers. It's safe to jump between v1.1 and v1.2 at any time or even have them concurrently accessing the same mailboxes. Dovecot v1.2 has a lot of new IMAP extensions implemented. The biggest change comes from CONDSTORE extension which adds a new concept of "modification sequences" (modseq for short). Each message has a modseq that increases whenever a flag is changed or when the message is expunged. The client can keep track of the highest seen modseq and request only changes done since the modseq. See QRESYNC (RFC 5162) for more information. Dovecot starts keeping track of the modseqs only when the first "CONDSTORE/QRESYNC enabling command" is executed. Before that no disk space is used for modseqs. When modseqs are enabled dovecot.index file uses 8 bytes per message more space. Other implemented IMAP extensions are: ESEARCH, SEARCHRES, WITHIN, ID and CONTEXT=SEARCH. Added thread indexes to optimize IMAP THREAD command. Only the first half of threading is currently optimized, the rest will hopefully follow later. Added a non-standard X-REFERENCES2 threading algorithm where threads are sorted by their latest message instead of the thread root message. There is also no base subject merging. This may be renamed and become part of SEARCH=INTHREAD extension some day. SEARCH=INTHREAD is still a draft, but the INTHREAD search key is already implemented by Dovecot v1.2. This is mostly useful with virtual mailboxes. Virtual mailboxes: http://wiki.dovecot.org/Plugins/Virtual Then there are also some internal API changes which will make some things easier. For example lib-storage now allows handling multiple different users at the same time.

[Dovecot] pam_dovecotpw anybody?
by Steinar Bang 02 Nov '08

02 Nov '08

Samba has pam_smbpass which is a PAM module that hooks into password changing, and changes the users' samba password (presumably used for NTLM auth?), when the users change their ordinary unix/linux password. http://gitweb.samba.org/?p=samba.git;a=tree;f=source3/pam_smbpass;h=c230a1b… It shouldn't bee too hard to take the code from here, combine it with dovecotpw and create a PAM module that changes the dovecot password in a way that can be used for cram-md5. Ideally it should read the /etc/dovecot/dovecot.conf (whereever it is), and find the path of the passwd-file and use that. Has anyone else looked into doing something like this?

[Dovecot] Backing Up
by Neil 02 Nov '08

What is the best way to do a (server-side) backup of all mail in a user's mail? I don't think I'm doing anything weird as far as configs go; here's dovecot -n if it helps: # 1.1.4: /etc/dovecot/dovecot.conf protocols: imaps listen: *, [::] ssl_cert_file: /etc/ssl/dovecot/cert.pem ssl_key_file: /etc/ssl/dovecot/key.pem login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login mail_location: maildir:~/.maildir auth default: mechanisms: plain login passdb: driver: pam args: * userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix

[Dovecot] feature request for managesieve build from packager
by seriv＠parkheights.dyndns.org 02 Nov '08

02 Nov '08

Hi everybody, dovecot-1.2 alpha3 with cmusieve, libsieve and managesieve are available as rpm packages for Sisyphus repository (http://ftp.altlinux.org/pub/distributions/ALTLinux/Sisyphus, and specs/patches are available at http://git.altlinux.org/people/seriv/packages/?p=dovecot.git and http://git.altlinux.org/people/seriv/packages/?p=dovecot-sieve.git) Thank you very much Timo and Stephan! I have a feature-request for managesieve configure and Makefiles: they depend on dovecot sources as they are used for build process. I think it would be very nice to have not just --with-dovecot parameter in configure parameters, but also --with-dovecot-includes and --with-dovecot-libs. The same about cmusieve plugin: dovecot has --enable-header-install parameter, but installed headers are not sufficient for building cmusieve, I need install libraries and then modify cmusieve's Makefiles by running something like: --- for f in `find . -name Makefile` do mv -f $f $f.orig sed -e's/\$(dovecotdir)\/src$\/lib\/.*\.a$/\$(libdir)\/dovecot\/modules\1/g' \ < $f.orig > $f done --- before make in %build section. -- With best regards, Sergey Ivanov.

[Dovecot] imap processes eating IO
by Ryan Rawdon 02 Nov '08

02 Nov '08

[Ignore the previous e-mail, I somehow sent it when I was trying to paste from clipboard] I recently migrated my dovecot/postfix setup to a new machine. After doing so, I have encountered a problem where imap processes get stuck in a loop eating loads of IO on the machine. Looking at the trace (snippet below), it looks like they are sitting and reading the inbox and other folders of certain users repeatedly. This seems to be triggered by the delivery of a new e-mail to the user's mailbox while they have an IMAP client connected, though I cannot say for sure. This had never happened before on the old machine. I'm certain more information would be useful, please let me know what I can provide to help! Trace of process 22342 - imap lstat64("/home/vmail/u13.net/ryan/Maildir/cur/1203440140.P6242Q0M41485.scarecrow:2,RSc", {st_mode=S_IFREG|0600, st_size=3079, ...}) = 0

[Dovecot] antispam plugin problem
by Eugene 01 Nov '08

01 Nov '08

Hi people! (Especially Johannes, probably =) I recently switched to DSPAM + antispam plugin combination. Mostly I am happy but there is a problem with calling dspam-exec in order to relearn the messages. Moving messages to spam folder does not work, giving the error message 'Failed to call dspam' to client. I tried to add some debug output and here are the results: This is the output of debug("calling dspam: %s %s %s %s %s %s %s", argv[0], argv[1], argv[2], argv[3], argv[4], argv[5], argv[6]); (debugv(argv) does not produce any output for some reason) Oct 26 02:37:12 qqqqq imap: antispam: calling dspam: /usr/contrib/bin/dspam --source=error --class=spam --signature=490387db858421194018847 --user genie (null) This is the captured output of forked process Oct 26 02:37:12 qsar imap: antispam: dspam returned: ^APdata stack: Out of memory when allocating 1073741840 bytes If I understand correctly, this message is produced by dovecot before it should have launched dspam executable. I don't know why it needs 1GB of stack space for that. Changing dspam to dspamc does not help. Interestingly enough, launching 'sendmail' in mailtrain mode works ok. Do you have any ideas about what is wrong? Best wishes Eugene

Hi dear All, Currently I'm configuring Dovecot+PostfixAdmin+PostgreSQL on FreeBSD 7 Stable and using Dovecot v1.1.3. I hope I've configured everything. But when I run /usr/local/etc/rc.d/dovecot start then dovecot doesn't seems to running. /var/log/maillog is only showing following.

[Dovecot] dovecot expire doesn't work (?)
by LÉVAI Dániel 31 Oct '08

31 Oct '08

Hi! I'm using dovecot-1.1.5 and trying to make the expire plugin work. What I've configured in dovecot.conf is the following: protocol imap,pop3,lda { mail_plugins = [...] expire } dict { expire = db:/var/dovecot/expire/expire.db } plugin { expire = spamassassin/SPAM 2 spamassassin/HAM 2 expire_dict = proxy::expire } I have a sieve rule, to copy certain messages to my "spamassassin/SPAM" folder. Then I want to expire those messages after 2 days (I think I've configured that under the plugin{} section in dovecot.conf). So the actual message saving is done by the dovecot's deliver, but I have the plugin loaded under the "protocol lda {}" section too. So I thought now I just have to wait 2 days, and run the expire-tool, and then it will expire the messages. Now I have three messages dated back to 10.25, but running the expire-tool outputs nothing. # dovecot --exec-mail ext /usr/local/libexec/dovecot/expire-tool --test Nothing in the logfiles, and nothing on the console. I have the /var/dovecot/expire directory: # ls -la /var/dovecot/expire/ total 1640 drwx------ 2 root wheel 512 Oct 26 19:47:53 2008 ./ drwxr-x--- 3 root wheel 512 Oct 27 07:57:42 2008 ../ -rw------- 1 root wheel 24576 Oct 27 13:00:01 2008 __db.001 -rw------- 1 root wheel 57344 Oct 27 13:00:01 2008 __db.002 -rw------- 1 root wheel 270336 Oct 27 13:00:01 2008 __db.003 -rw------- 1 root wheel 98304 Oct 27 13:00:01 2008 __db.004 -rw------- 1 root wheel 49152 Oct 27 13:00:01 2008 __db.005 -rw------- 1 root wheel 32768 Oct 26 19:47:37 2008 expire.db -rw------- 1 root wheel 10485760 Oct 27 14:22:08 2008 log.0000000001 It contains the familiar BDB files, so I think it works, although the expire.db's modify time is yesterday, but deliver saved some messages also today to the spamassassin/SPAM folder. What could be the problem? Am I missing something? Thanks! Daniel -- LEVAI Daniel PGP key ID = 0x4AC0A4B1 Key fingerprint = D037 03B9 C12D D338 4412 2D83 1373 917A 4AC0 A4B1

[Dovecot] Problem with Dovecot 1.1.4 and dovecot-antispam 20080829
by Guillaume Hilt 31 Oct '08

31 Oct '08

Hi there, I'm running a server under Gentoo 64 with postfix 2.5.5, Dovecot 1.1.4-r1 and Dovecot-antispam 20080829 (all are the lastest versions availables under Portage). I ran into a problem when I log in to my mailbox : Oct 30 10:39:23 ks29138 dovecot: IMAP(hiltg): Loading modules from directory: /usr/lib64/dovecot/imap Oct 30 10:39:23 ks29138 dovecot: IMAP(hiltg): Module is for different version 1.1.1: /usr/lib64/dovecot/imap/lib90_antispam_plugin.so Oct 30 10:39:23 ks29138 dovecot: Fatal: IMAP(hiltg): Couldn't load required plugins Is there another version for Dovecot 1.1.4 out there or must I go back to 1.1.1 ? Thanks, Guillaume

[Dovecot] Dovecot read only for users
by JC 31 Oct '08

31 Oct '08

All, I have hopefully a base question. How do you give users only read access to their inbox and folders? If I use chmod 600 they have full access. If I do a 400 they have read access but cannot access their inbox. The config file is the out of the box config other than advertising IMAP and IMAPS. Any help will be appreciated. Thanks.

[Dovecot] Startup info message
by Athan Dimoy 31 Oct '08

31 Oct '08

Hi folks, I'm using the latest Dovecot 1.16 with Postfix for my FreeBSD box. Since v1.1.4 (if i remember correctly), the following message is displayed whenever starting Dovecot. "Info: If you have trouble with authentication failures, enable auth_debug setting. See http://wiki.dovecot.org/WhyDoesItNotWork" Besides that, Dovecot works great but I wonder what this message is all about. I've searched wiki and mailing list but didn't find anything related. PS: I removed Dovecot removing all stalled files and directories and reinstalled it from scratch. Still the message is displayed whenever it starts. Any idea? Athan

[Dovecot] SIGBART/SIGSEGV while SELECTing virtual folder
by Lars Noschinski 30 Oct '08

30 Oct '08

Hello! I just installed Dovecot's latest nightly build (20081020) and tried the virtual folder features. I started with a really simple "all" folder: | # virtual/all | * | all But selecting this folder causes dovecot to panic (in most cases). While trying to debug this, I got slightly different results and I am not really sure yet if this is just non-deterministic, depends on some cached dovecot data or if there is some difference between the debug build or my rudimentary, unpatched debian package (which lacks the debug symbols). The results below are from a build with --prefix set to a clean, temporary directory. Similar problems occured also with the alpha2 release, which caused me to try the latest nightly build. --------------------------------------------------------------------- % ./sbin/dovecot --exec-mail ext /usr/bin/gdb ./libexec/dovecot/imap GNU gdb 6.8-debian Copyright (C) 2008 Free Software Foundation, Inc.

[Dovecot] mail_executable's process environment
by Mike Malsman 30 Oct '08

30 Oct '08

Hello, I recently had to get Dovecot 1.1.4 to write to a "pop3/imap-before- smtp" db such that my MTA could permit relay after a successful authentication with Dovecot. The 'pop3' and 'imap' processes are executed only after a successful auth, so replacing them with wrappers which write to the db seemed the natural choice. Lo and behold, someone thought of something like this, as the 'mail_executable' directive exists - neat. Upon inspection of the processes' environment I'm pleased to see that there's a load of useful information in there. However, one essential component in my case is the destination network address, which is missing. I added it with the attached patch, exposed as 'LOCAL_IP'. Works for me. Is this something that would be useful to anyone else? -Mike

[Dovecot] [dovecot] Enable logging of all client commands in dovecot-1.2.alpha3
by Jonathan Siegle 30 Oct '08

30 Oct '08

Hello, I would like to log all IMAP client commands sent to dovecot. The format would be time pid command arguments. I reviewed http://wiki.dovecot.org/Logging and started digging through dovecot-1.2.alpha3/src/master . I don't need this turned on all the time, just enough to see how clients do things and I don't need to see passwords. Any tips would be appreciated. -Jonathan

[Dovecot] benchmark dovecot
by Mathieu Kretchner 30 Oct '08

30 Oct '08

Hello, We would like to do a feed back to this active mailing list. We are working on a migration project from cyrus to dovecot. And we have just completed the benchmark sequence. As I say, this benchmark is here only to show that our old imap server is out to date. I would not be the source of controversy at all, so I try to explain my approach. Because the only thing I found was this old oriented benchmark : http://www.isode.com/whitepapers/mbox-benchmark.html We've tried to do our tests, here you could find our results : http://www-sop.inria.fr/members/Mathieu.Kretchner/dotclear/index.php/2008/1…

[Dovecot] Enh-Req: Mark As Read When Delivered
by Neil 30 Oct '08

30 Oct '08

I'm under the impression bug-reports are supposed to go to the list, so hopefully it's okay if I put in a feature request here too (assuming it's not already implemented; but it doesn't look like it). Basically, all I would like to do is be able to sometimes deliver mail as already mail into mail boxes. Is there some way to do this? If not, could a flag perhaps be added to deliver to do it? (And Sieve; but for now I think procmail still has much higher adoption, and thus having it in deliver would be rather key...) Thanks, -Neil.

[Dovecot] INBOX stored in AFS
by Hans-Werner Paulsen 30 Oct '08

30 Oct '08

Hello, currently we are storing the incoming mail in the user's home directory, which is within a distributed filesystem called AFS (OpenAFS). Accessing the "mbox" file directly (using the distributed filesystem) works fine with mutt, thunderbird, ... To access the INBOX from a machine, which does not have access to this distributed filesystem, we are using IMAP (UW-imap). Now I wanted to check if dovecot can do the job (maybe faster than UW), and I had the following problem: This is my configuration: ------------------------------------------------------------------------------- # 1.1.4: /opt/dovecot-1.1.4/etc/dovecot.conf log_path: /var/log/dovecot ssl_cert_file: /etc/ssl/certs/imapd.pem ssl_key_file: /etc/ssl/keys/imapd.pem login_dir: /var/run/dovecot/login login_executable: /opt/dovecot-1.1.4/libexec/dovecot/imap-login first_valid_uid: 100 mail_location: mbox:~/Mail:INBOX=~/.maildir/incoming mail_debug: yes mmap_disable: yes mail_nfs_storage: yes mail_nfs_index: yes mbox_write_locks: fcntl mbox_dirty_syncs: no mbox_lazy_writes: no mail_executable: /opt/dovecot-1.1.4/libexec/dovecot/afs-token /opt/dovecot-1.1.4/libexec/dovecot/imap auth default: verbose: yes debug: yes passdb: driver: pam args: setcred=yes session=yes dovecot userdb: driver: passwd ------------------------------------------------------------------------------- When I start my imap-client, I see the content of the INBOX, and I can read, delete, ... the different entries. But when new mail arrives dovecot (and my imap-client) will never notice this. And when I quit my imap-client the dovecot imap server will write back its view of the INBOX, and delete this new mail. This seems to be a problem related to AFS. I poked in the dovecot code and have the following theory: dovecot opens the INBOX R/W, dovecot calls "stat" on the INBOX file periodically to look for modifications. But this does not work, because this machine will stat the local copy (AFS cache) of the INBOX as long as this file is still open R/W. My questions: Is it possible to have a configuration, that the INBOX file is not left open when stat-ing this file? Or is it possible to open the INBOX file R/W only when it us locked? Or is it necessary to modify the code?

Re: [Dovecot] First release (v0.1.0) of the new Sieve implementation for Dovecot v1.2
by seriv＠parkheights.dyndns.org 30 Oct '08

30 Oct '08

Thank you Timo, it was my mistake. In 'plugin {}' section line 'sieve = /var/sievescripts/%n/sieve' worked for both cmusieve and sieve plugins. Command 'fileinto "INBOX/foo/bar"' with private namespace configuration you proposed - also worked in both plugins. I suspected that they have different behavior: cmusieve saved message into INBOX/foo/bar, while sieve - into foo/bar as in the deliver log I'm pasting here. But both messages were filed into the same mail folder. Difference in the logging, I think, is not a big problem. --- ls -l Maildir/.foo.bar/new total 8 -rw------- 1 seriv seriv 513 Oct 30 01:57 1225331850.M790093P1351.sisyphus.office.omniti.com,W=526 -rw------- 1 seriv seriv 518 Oct 30 01:59 1225331966.M468658P1400.sisyphus.office.omniti.com,W=531 tail -n 18 /var/log/deliver/dovecot-deliver.log --- deliver(seriv): Oct 30 01:57:30 Info: Loading modules from directory: /usr/lib64/dovecot/modules/lda/ deliver(seriv): Oct 30 01:57:30 Info: Module loaded: /usr/lib64/dovecot/modules/lda//lib90_cmusieve_plugin.so deliver(seriv): Oct 30 01:57:30 Info: Namespace: type=private, prefix=INBOX/, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes deliver(seriv): Oct 30 01:57:30 Info: maildir: root exists (/home/seriv/Maildir) deliver(seriv): Oct 30 01:57:30 Info: maildir++: root=/home/seriv/Maildir, index=, control=, inbox=/home/seriv/Maildir deliver(seriv): Oct 30 01:57:30 Info: cmusieve: Using sieve path: /var/sieve-scripts/seriv.sieve deliver(seriv): Oct 30 01:57:30 Info: cmusieve: Executing script /var/sieve-scripts/seriv.sievec deliver(seriv): Oct 30 01:57:30 Info: Namespace INBOX/: Using permissions from /home/seriv/Maildir: mode=0644 gid=-1 deliver(seriv): Oct 30 01:57:30 Info: msgid=<20081030015649.B7936140A88(a)sisyphus.office.omniti.com>: saved mail to INBOX/foo/bar deliver(seriv): Oct 30 01:59:26 Info: Loading modules from directory: /usr/lib64/dovecot/modules/lda/ deliver(seriv): Oct 30 01:59:26 Info: Module loaded: /usr/lib64/dovecot/modules/lda//lib90_sieve_plugin.so deliver(seriv): Oct 30 01:59:26 Info: Namespace: type=private, prefix=INBOX/, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes deliver(seriv): Oct 30 01:59:26 Info: maildir: root exists (/home/seriv/Maildir) deliver(seriv): Oct 30 01:59:26 Info: maildir++: root=/home/seriv/Maildir, index=, control=, inbox=/home/seriv/Maildir deliver(seriv): Oct 30 01:59:26 Info: sieve: using sieve path: /var/sieve-scripts/seriv.sieve deliver(seriv): Oct 30 01:59:26 Info: sieve: opening script /var/sieve-scripts/seriv.sieve deliver(seriv): Oct 30 01:59:26 Info: sieve: executing compiled script /var/sieve-scripts/seriv.sieve deliver(seriv): Oct 30 01:59:26 Info: sieve: msgid=<20081030015911.576FC140A88(a)sisyphus.office.omniti.com>: stored mail into mailbox 'foo/bar' -- WBR, Sergey Ivanov. ----- "Timo Sirainen" <tss(a)iki.fi> wrote: > On Wed, 2008-10-29 at 20:31 +0100, Stephan Bosch wrote: > > sergey ivanov schreef: > > > Hi Stephan, > > > Thank you for quick fix.

Did you try dovecot-sieve-1.1 with dovecot 1.2 to verify? I'll ask Timo about this. What is the configuration of your mail store.

[Dovecot] FTS index generation
by Dave McGuire 30 Oct '08

30 Oct '08

Hi folks. I'm experimenting with the Squat plugin. I can execute search commands via direct interaction with IMAP, but I never see the expected dovecot.index.search index file appear in the spool. I'm concerned that I've misconfigured something that is preventing the creation of those indices. Is there a facility to have the squat plugin generate debugging messages so I can see what it's doing? Thanks, -Dave -- Dave McGuire Ahh, you voted for Bush? Port Charlotte, FL Happy now?

[Dovecot] Embedded "From<space>" Lines
by Lennart Lövstrand 29 Oct '08

29 Oct '08

Hi. As some of you may remember, I reported a problem a while back where dovecot 1.1.beta14 (as well as dovecot 1.0) would corrupt mbox-style mailboxes by ignoring the Content-Length header and breaking up messages with embededed "From<space>" lines. I recently downloaded Dovecot 1.1.5 and noted to my pleasure that this bug now has been fixed. That's great! This fix envolves checking to see if the expected_body_size (from the Content-Length header) is larger than the body_size produced by the "From<space>" scanner, and if so, if there is a valid "From<space>" line at the "expected" end of the message. However, I also noted that there's a case which the fix doesn't cover, and that's where the "From<space>" line appears as the first line of the body of the message. When this happens, the body_offset will point to the blank line between the headers and the body and not the actual first line of the body. This will cause the stream to be mispositioned at the time of the "From<space>" verification check in istream_raw_mbox_get_body_size and the (actually correct) expected_body_size will be rejected. I have enclosed a simple diff that will work around this by adjusting the body_offset to point to the next line at the time of call to istream_raw_mbox_is_valid_from in istream_raw_mbox_get_body_size. This appears to handle the problem correctly in all the test cases I have. To anyone else who has run into this problem and gotten corrupted mailboxes as a result, I can also offer an mbox checker that will attempt to detect and repair this problem in existing mailboxes as well as inspect them for other problems. I'm not ready to send it out for a full release yet, but interested beta testers are invited to contact me directly. Cheers, --Lennart

Now i am setting up the quota warning, with this in dovecot.conf: quota_warning = storage=70%% /usr/bin/quota_warning.sh 70 In the plugin section naturally. All seems to work fine, the quota is calculated right, but seems the script is not executed... In dovecot logs i have this: deliver(test(a)test.com): Oct 27 15:14:53 Info: Quota warning: bytes=10752000 (70%) messages=0 (0%) command=/usr/bin/quota_warning.sh 70 But...nothing happens. My quota_warning.sh is this: #!/bin/bash PERCENT=$1 echo "/usr/lib/dovecot/deliver -d "$USER" -c /usr/local/etc/dovecot-nowarning.conf" > /var/log/quotanotify cat << EOF | /usr/lib/dovecot/deliver -d "$USER" -c /usr/local/etc/dovecot-nowarning.conf From: postmaster(a)mediaservice.net Subject: quota warning Your mailbox is now $PERCENT% full. EOF I have added the echo for debug pourpose, but no file was created, so the script is not executed. I thinked is a permission problem, but seems not. Now the script is like this: -rwx--x--x 1 dovecot dovecot 317 Oct 27 15:30 /usr/bin/quota_warning.sh What can be the problem? Stuck!!!

[Dovecot] Dovecot pop3 and SonicWall?
by Brandon Lamb 29 Oct '08

29 Oct '08

Hello Has anyone else run into a problem with dovecot pop3 and sonicwall? A week after switching to dovecot we had two local customers call and report they could no longer download emails with attachments. It turned out to be the email macro filter on the router. After the first report I thought maybe the customer had just changed something or it was a fluke, but then a day later we had the second call with the same issue. For some reason, after us switching the sonicwall's email macro filter was catching any attachments as a threat. I couldnt see how changing pop3 servers could affect that, but I guess anything is possible. I just emailed sonicwall and am waiting for a response from them now as well. Hopefully maybe someone has heard of this before. Unfortunately, I dont know if this was pure coincidence, or if both customers happened to have updated their sonicwall software, or maybe it autoupdates, I have no information on it.Of course to them it looks like we broke it. We just had them both turn this rule off for now.

[Dovecot] Best configuration of dovecot for limit Outlook problems with IMAP
by Alessio Cecchi 29 Oct '08

29 Oct '08

Hi, in some installation where users using IMAP and Outlook Express I have some problems. Outolook randomly presents problems in messages retrieving, for example: "Outlook Express is unable to retrieve the requested message because the server no longer has the message available.... server response: Fecth Completed" or "Message could not be displayed" error message when I try to view an Outlook Express e-mail message I'm using dovecot 1.1.4 with qmail and vpopmail. This is my dovecot configure options: ./configure --prefix=/usr --sysconfdir=/etc/dovecot --localstatedir=/var --with-ssldir=/etc/ssl and this my dovecot config: # dovecot -n # 1.1.4: /etc/dovecot/dovecot.conf log_path: /var/log/dovecot/dovecot-err.log info_log_path: /var/log/dovecot/dovecot.log ssl_cert_file: /etc/apache2/ssl/comun.crt ssl_key_file: /etc/apache2/ssl/comun.key disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login login_greeting: Ready login_process_per_connection: no first_valid_uid: 89 last_valid_uid: 89 first_valid_gid: 89 last_valid_gid: 89 mail_uid: 89 mail_gid: 89 mail_location: maildir:~/Maildir mail_debug: yes mail_plugins: quota imap_quota imap_client_workarounds: outlook-idle delay-newmail namespace: type: private separator: . prefix: INBOX. inbox: yes list: yes subscriptions: yes auth default: verbose: yes debug: yes passdb: driver: checkpassword args: /home/vpopmail/bin/vchkpw userdb: driver: prefetch args: uid=89 gid=89 home=/home/vpopmail/domains/%d/%u plugin: quota: maildir What further changes to the configuration of dovecot could I do?

[Dovecot] Dovecot and quota enforcement - only reporting?
by dovecot＠corwyn.net 29 Oct '08

29 Oct '08

I'm currently setting up postfix and dovecot with virtual users (mysql), imap, and quotas. I'm setting the quotas using mysql. I have quotas working correctly, and I can telnet into the imap server, and submit . getquotaroot inbox and get back valid quota information. I get a maildirsize file in the Maildir directory. Very cool. When I delete mail and expunge it, the quota updates. However, inbound email doesn't appear to update the quota. Two questions, probably related: What causes the quota (which I presume is the maildirsize file) to update? Is there any actual quota enforcement, or just reporting? Because if I send mail to an account, even if it currently reporting (via maildirsize or . getquotaroot) that the user is over quota, they still can send and receive email. Thanks!

[Dovecot] Authentication Error Message formats
by Albert E. Whale 29 Oct '08

29 Oct '08

I have been using UW's IMAP server and I am converting to Dovecot for Maildir support. When a user fails authentication, or a user does not exist, it appears that the same message is used for these events. Is there a way to indicate that the user does not exist (Invalid user), and authentication Failure (Failed Password)? Clearly these two failures indicate a different error in the system. One that some forgot their password, the other indicates a dictionary attack. -- Albert E.

[Dovecot] Empty/corrupt mail leads to duplicate delivery
by Marc Herbrechter 29 Oct '08

29 Oct '08

Hi, when the attached mail was stored in a maildir, fetching mail via POP3 lead to multiple delivery of mails in that maildir to the client (Outlook). I replaced the domain with dots. This is the dovecot configuration: --snip-- protocols = imap imaps pop3 pop3s listen = * disable_plaintext_auth = no ssl_cert_file = /etc/ssl/dovecot/server.pem ssl_key_file = /etc/ssl/dovecot/server.key mail_location = maildir:~/.maildir protocol pop3 { pop3_uidl_format = %08Xu%08Xv } auth default { mechanisms = plain passdb pam { args = "*" } userdb passwd { } user = root socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } --snip-- Version: dovecot-1.1.4-r1 (Gentoo) Gentoo applies the attached "expire" patch. I tried to reproduce the behavior, but when I send an empty mail via telnet, nothing happens. The box is running Amavis, don't know if that helps. -- Mit freundlichen Grüßen, with kind regards, Marc Herbrechter <mh(a)zebroc.de>

[Dovecot] Keep the email on the server
by Rubens A. Mascari 29 Oct '08

29 Oct '08

Hello, I migrate my server POP3/IMAP recently the Courier-IMAP for Dovecot and am having problems when the user configures your e-mail client to leave a copy of mail on the server. All mail in the inbox, are brought all the time that you check your mailbox input via POP3, causing a large traffic of unnecessary data every time. In my opinion you should bring only the new mail, unread. Can you tell me if this is a configuration issue on Dovecot? Thank you all -- Att.

[Dovecot] mbox to Maildir conversion
by Albert E. Whale 28 Oct '08

28 Oct '08

I've been running a mbox solution using UW's IMAP server. I've run it for years. Now do to heavy message volumes, I've decided to to take the plunge to convert to the Maildir format. I am currently testing a single user, and have successfully converted the mail messages from mbox to Maildir format, and now I am setting up the procmail tool to place the messages into the correct folder. I have been following the http://wiki.dovecot.org/Migration/MailFormat formula, but now have a question. New Messages are now being placed into the ~user/Maildir/new folder. However, when I attempt to retrieve those messages, Dovecot does not find them. Why not? -- Albert E.

[Dovecot] Possible header parsing problem
by Eric Stadtherr 28 Oct '08

28 Oct '08

Hi, I ran into a problem wherein my mail client (RoundCube) would not display a message from a Dovecot IMAP server (claiming that the message had no content). The raw source of the message looked fine, but the body structure returned by Dovecot only had the first text/plain part and not the alternative text/html part. The message looks like: ... headers removed ... X-Mailer: Lotus Notes Release 6.5.1 January 21, 2004 Message-ID: <...> From: user(a)host.domain Date: Mon, 20 Oct 2008 14:15:55 -0600 Content-Type: multipart/alternative; boundary="=_alternative 006F3A73872574E8_=" This is a multipart message in MIME format. --=_alternative 006F3A73872574E8_= Content-Transfer-Encoding: 7bit Content-Type: text/plain; charset=us-ascii blah blah blah --=_alternative 006F3A73872574E8_= Content-Transfer-Encoding: 7bit Content-Type: text/html; charset=us-ascii <br><font size=2 face="sans-serif">blah blah blah in HTML</font> --=_alternative 006F3A73872574E8_=-- I did a little bit of tracing through the parsing code (message-header-parser.c:message_parse_header_next()) and it appeared that the boundary in the Content-Type header was not parsed correctly, evidently because the header line was folded in the middle of the boundary string. RFC 822 appears to allow folding in a quoted string like this (§3.3 "quoted-string"), so I'm curious whether the parsing is working correctly. Thanks for your help! Here is my Dovecot information: version: 1.1.4 "dovecot -n" output: # 1.1.4: /usr/local/etc/dovecot.conf Warning: fd limit 256 is lower than what Dovecot can use under full load (more than 384).

[Dovecot] Gah, pop3 falling over
by Brandon Lamb 27 Oct '08

27 Oct '08

Why would I be seeing a million of these? dovecot: 2008-10-27 09:12:33 Warning: chdir(/mail/mail/domain/u/username/) blocked for 18 secs Two servers were working fine and then all of a sudden this morning bam 500 load and theres a million dovecots and tons of these lines in the logs. It is like everyone gets up at exactly 8:30 and hits the pop3 server at once. Anyway, dovecot 1.1.5, nfs mount, debian lenny/sid amd64, 2.6.26-1-amd64 i had the performance mode options for login configured, i just set back to the single process per login though, I think that hasnt fallen over that way but I really dont remember anymore. I included the dovecot -n using the suggest performance login settings?

[Dovecot] Released v1.1.5 and v1.2.alpha3
by Timo Sirainen 27 Oct '08

27 Oct '08

http://dovecot.org/releases/1.1/dovecot-1.1.5.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.5.tar.gz.sig http://dovecot.org/releases/1.2/alpha/dovecot-1.2.alpha3.tar.gz http://dovecot.org/releases/1.2/alpha/dovecot-1.2.alpha3.tar.gz.sig A combined release announcement for a change. :) Largest changes since v1.1.4: * Dovecot prints an informational message about authentication problems at startup. The message goes away after the first successful authentication. This hopefully reduces the number of "Why doesn't my authentication work?" questions. + Maildir/dbox: Try harder to assign unique UIDVALIDITY values to mailboxes to avoid potential problems when recreating or renaming mailboxes. The UIDVALIDITY is tracked using dovecot-uidvalidity* files in the mail root directory. + Many logging improvements - In some conditions Dovecot could have stopped using existing cache file and never used it again until it was deleted. - pop3 + Maildir: Make sure virtual sizes are always written to dovecot-uidlist. This way if the indexes are lost Dovecot will never do a huge amount of work to recalculate them. - mbox: Fixed listing mailboxes in namespaces with prefix beginning with '~' or '/' (i.e. UW-IMAP compatibility namespaces didn't work). - dict quota: Don't crash when recalculating quota (when quota warnings enabled). - Fixes to handling "out of disk space/quota" failures. - Blocking passdbs/userdbs (e.g. PAM, MySQL) could have failed lookups sometimes when auth_worker_max_request_count was non-zero. - Fixed compiling with OpenBSD Largest changes since v1.2.alpha2: + Added userdb checkpassword (by Sascha Wilde) + Autocreate plugin: http://wiki.dovecot.org/Plugins/Autocreate + Listescape plugin: http://wiki.dovecot.org/Plugins/Listescape - All the same fixes as for v1.1.5 I was thinking about waiting for Kolab people's work for shared mailbox support to get done, get that code to v1.2 tree and then release v1.2.beta1 with feature freeze.

[Dovecot] Problems with the pop3 part of dovecot
by Brandon Lamb 27 Oct '08

27 Oct '08

Hello, I originally just typed up a 5 paragraph essay on my problems but just deleted it all. basically I need to find out where to start looking to find out what is the problem with my dovecot pop3 setup. I switched from courier imap/pop3 to dovecot imap/pop3. I have had super high loads (40+ and overnight one server went to 511) and its been a nightmare fighting with this new setup for the last two weeks. I did manage to narrow the problem down to it being with the pop3 part of dovecot. I am not sure why the load keeps going so high. The first week I attributed it to users having to redownload mail and reindex (we were aware of the UIDL problem), but two weeks later one of my machines overnight went to 511. I have changed so many config options to try to make it work that I have become overwhelmed and feel like I have tried everything to get the right settings. I am running four 64bit machines with amd 9850 cpus, 4 gigs ram, the mailstore is nfs mounted, the nfs server is using xfs. Debian lenny/sid. I dont know what to do, I am almost debating going back to courier pop3 and going through the week of support calls of customers downloading mail again but that is a last ditch effort. I can understand if i just need to wait it out while things are indexed for dovecot and stuff, but machines falling over and loads of 40 to 500 just for dovecot seems not right. so, where do I start?

[Dovecot] Problem with quota dovecot as lda and mysql
by Claudio Prono 27 Oct '08

27 Oct '08

Hello to all, That is my situation: I am trying to use dovecot as LDA with postfix, mysql e postfixadmin. So, all the users are stored in mysql, with quota password and all other things. All works properly, except for quota. I am trying to do some tests, but is not clear to me how to debug that problem. Scenario: user with 15 Mb of quota. That is my dovecot.conf (dovecot version 1.1.3 on OpenSuSE 11.0): dovecot -n # 1.1.3: /etc/dovecot/dovecot.conf log_path: /var/log/dovecot-err.log info_log_path: /var/log/dovecot-inf.log protocols: imap imaps pop3 pop3s 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 first_valid_uid: 51 last_valid_uid: 51 first_valid_gid: 51 last_valid_gid: 51 mail_location: maildir:/var/mail/virtual/%d/%u 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 imap_quota mail_plugins(imap): quota 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 imap_client_workarounds(imap): outlook-idle imap_client_workarounds(pop3): pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): %Mf auth default: passdb: driver: sql args: /etc/dovecot/dovecot-mysql.conf userdb: driver: passwd userdb: driver: sql args: /etc/dovecot/dovecot-mysql.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 plugin: quota: maildir quota: maildir:user quota And this is my dovecot-mysql.conf: driver = mysql connect = host=127.0.0.1 port=3306 user=postfix password=XXXXXXXXXXX dbname=postfix default_pass_scheme = MD5-CRYPT password_query = SELECT username as user, password, '/var/mail/virtual/%d/%u' as userdb_home,'maildir:/var/mail/virtual/%d/%u' , 51 as userdb_uid, 51 as userdb_gid FROM mailbox WHERE username = '%n@%d' AND active = '1' user_query = SELECT maildir, 51 AS uid, 51 AS gid, concat('dirsize:storage=', ROUND( mailbox.quota / 1024 ) ) AS quota FROM mailbox WHERE username = '%u' AND active = '1' But.. when i send a mail that "overquota" the mailbox, nothing happens, the mail is normally delivered to maildir and the quota is not considered. An example of the process: I take a mailbox with 15Mb of quota, like test(a)test.com: Email Nome Quota (MB) Ultima modifica Attivo test(a)test.com test 15 2008-10-27 11:47:43 SI <edit-active.php?username=test%40test.com&domain=test.com> modifica <edit-mailbox.php?username=test%40test.com&domain=test.com> cancella <delete.php?table=mailbox&delete=test%40test.com&domain=test.com> I try to send an email to it: Oct 27 11:48:53 dns postfix/smtpd[3489]: connect from cla.mediaservice.pri[192.168.87.70] Oct 27 11:48:53 dns postfix/smtpd[3489]: D8DF2837: client=cla.mediaservice.pri[192.168.87.70] Oct 27 11:48:53 dns postfix/cleanup[3494]: D8DF2837: message-id=<49058EB2.5080208(a)atpss.net> Oct 27 11:48:58 dns postfix/qmgr[2636]: D8DF2837: from=<claudio.prono(a)atpss.net>, size=7716371, nrcpt=1 (queue active) Oct 27 11:48:58 dns postfix/smtpd[3489]: disconnect from cla.mediaservice.pri[192.168.87.70] Oct 27 11:48:59 dns postfix/pipe[3496]: D8DF2837: to=<test(a)test.com>, relay=dovecot, delay=5.6, delays=4.9/0/0/0.71, dsn=2.0.0, status=sent (delivered via dovecot service) Oct 27 11:48:59 dns postfix/qmgr[2636]: D8DF2837: removed Fine, the mail was put into mailbox. dns:/var/mail/virtual/test.com/test@test.com # du -h 0 ./cur 7.3M ./new 0 ./tmp 7.3M .

[Dovecot] Bug? auth(default) Authentication client gave a PID of existing connection
by Brandon Lamb 26 Oct '08

26 Oct '08

Hello, My first time on this list, just switched from courier imap/pop3 system to dovecot. Imap part is great, pop3 seems to suffer, been fighting it for a week. Anyway, the reason for this post is that I have seen these pop up in my logs, and on one of my mailheads there were some 50 lines of this dovecot: 2008-10-26 09:33:54 Error: auth(default): BUG: Authentication client gave a PID 15661 of existing connection Is this really a bug or anything to be concerned with? I just installed 1.1.5. I am using Debian lenny/sid on amd64, phenom 9850 4g ram, nfs mounted maildir format xfs storage.

[Dovecot] Dovecot dies with PAM error?
by Jason Walton 26 Oct '08

26 Oct '08

Just setup a new server on the weekend with Ubuntu 8.10 beta, and Dovecot 1.1.4. Every now and then, the IMAP server dies, and won't let users authenticate. It happens about once or twice a day. In /var/log/mail.log, you can see dovecot complaining about critial errors: Oct 21 14:46:16 tachikoma dovecot: imap-login: Login: user=<jason>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, TLS Oct 21 14:46:16 tachikoma dovecot: IMAP(jason): Disconnected: Logged out bytes=769/9124 Oct 21 14:47:15 tachikoma dovecot: auth-worker(default): pam(jason,127.0.0.1): pam_start() failed: Critical error - immediate abort Oct 21 14:47:17 tachikoma dovecot: imap-login: Disconnected (auth failed, 1 attempts): user=<jason>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, TLS If I have a look at /var/log/auth.log, I see: Oct 21 14:47:15 tachikoma dovecot-auth: PAM _pam_init_handlers: error reading /etc/pam.d/dovecot Oct 21 14:47:15 tachikoma dovecot-auth: PAM _pam_init_handlers: [Critical error - immediate abort] Oct 21 14:47:15 tachikoma dovecot-auth: PAM error reading PAM configuration file Oct 21 14:47:15 tachikoma dovecot-auth: PAM pam_start: failed to initialize handlers This sounds ominous. If I try to cat /etc/pam.d/dovecot, though, the file is obviously there: jason@tachikoma:/var/log$ cat /etc/pam.d/dovecot #%PAM-1.0 @include common-auth @include common-account @include common-session And restarting dovecot seems to fix the problem. Dovecot WAS running just fine, servicing mail all day long, and then suddenly it won't read the PAM config file, and then it won't let anyone log in until I log in and kill it. Any ideas? My IMAP client is either Thunderbird or Roundcube, if that's relevant.

[Dovecot] Bug in QRESYNC SELECT/EXAMINE behavior
by Michael M. Slusarz 24 Oct '08

24 Oct '08

RFC 5162 [3.1] states that a QRESYNC should return all changes in a SELECT/EXAMINE since the given modseq. In the following case, it looks like there is an off-by-1 error somewhere: C: A64 SELECT "TestMailboxTest" (QRESYNC (1224531494 6 1,3:5)) [MMS: MODSEQ given is 6] S: * OK [CLOSED] S: * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) S: * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. S: * 4 EXISTS S: * 0 RECENT S: * OK [UNSEEN 1] First unseen. S: * OK [UIDVALIDITY 1224531494] UIDs valid S: * OK [UIDNEXT 6] Predicted next UID S: * OK [HIGHESTMODSEQ 6] [MMS: HIGHESTMODSEQ is 6 - the same as our cache, so there should be no need for an update] S: * 2 FETCH (MODSEQ (6) UID 3 FLAGS (\Deleted)) [MMS: ...but we get this FETCH that contains the MODSEQ ID of 6, which we have already told the server we are aware of] S: A64 OK [READ-WRITE] Select completed. In other words, I don't think that "2 FETCH ..." should be in the server response - it is duplicative information as to what is already cached on the client. michael

[Dovecot] service imaps.
by Mauro Sanna 24 Oct '08

24 Oct '08

In dovecot.conf protocol imaps is set to port 10943. ssl_listen = *:10943 The standard port for imaps is 993. So why it is set to 10943?

[Dovecot] dovecot 1.2: SEGV in acl plugin when selecting a shared mailbox
by Sascha Wilde 24 Oct '08

24 Oct '08

Hi Timo, there is a bug in the acl plugin (in head, _without_ our acl changes), which causes an segfault on selecting a shared folder. * OK [CAPABILITY ...] Dovecot ready. x login 1(a)example.com secret x OK [CAPABILITY ...] Logged in y select "users/2(a)example.com/INBOX/bla" - Peer has closed the GNUTLS connection The dovecot.log shows a segfault: [...] child 4507 (imap) killed with signal 11 This _only_ happens when the shared mailbox wasn't accessed in the same session by any other means like MYRIGHTS or LSUB (when subscribed). After doing one of those selecting works too... If it helps I can generate a gdb backtrace. cheers sascha -- Sascha Wilde OpenPGP key: 4BB86568 http://www.intevation.de/~wilde/ http://www.intevation.de/ Intevation GmbH, Neuer Graben 17, 49074 Osnabrück; AG Osnabrück, HR B 18998 Geschäftsführer: Frank Koormann, Bernhard Reiter, Dr. Jan-Oliver Wagner

No, the protocol (IMAP/POP3) is irrelevant. The important part to note (and where I suspect your problem is) is that the folder, as far as your client (Thunderbird) is concerned, is "Maildir/", the "Maildir/ new/" directory is part of Maildir's internal format. That is to say, you should never be putting "Maildir/(new|cur|tmp)" as a mailbox name into a client, just "Maildir/". -N.

[Dovecot] ManageSieve v0.11.0 released for Dovecot 1.2.alpha3
by Stephan Bosch 24 Oct '08

24 Oct '08

Hello Dovecot users, I have composed a release of the ManageSieve service for Dovecot v1.2. I also added two new capabilities that were added to the ManageSieve specification. Just like the last few releases, this new release supports the new Sieve plugin already. Change Log v0.11.0 ------------------- * Upgraded to Dovecot v1.2 * Added support for new ManageSieve capabilities RENAME and NOOP * Moved sieve settings to plugin {} section of config file. Now the settings `sieve` and `sieve_dir` in the plugin section are used for both the Sieve plugin and the ManageSieve service, avoiding the posibility of accidental differences in configuration. Installation ------------ The full installation procedure and other relevant information regarding ManageSieve is supposed to be available on the Dovecot wiki: http://wiki.dovecot.org/ManageSieve However, the changes regarding the config file are not properly described there yet. Refer to the package's README file in stead. New release: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.0.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.0.tar.gz.s… I have released a new patch for Dovecot v1.2 as well: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.alpha3-managesieve-0.11.0.d… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.alpha3-managesieve-0.11.0.d… My public key (id: 3DFBB4F4) can be found at wwwkeys.pgp.net.

[Dovecot] logging IMAP username rather than UNIX username
by Dale Gallagher 23 Oct '08

23 Oct '08

Hi there I'd like to change my setup to log the _actual_ IMAP user's login, rather than the UNIX username. My system uses a virtual uid setup with qmail, where the mailboxes are owned by the 'vmail' user and authentication is via checkpassword using user%domain (ie email, just with % instead of @). So dovecot is recording _all_ logins as: imap-login: Login: user=<vmail>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured I have the following log format specified: login_log_format_elements = user=<%u> method=%m rip=%r lip=%l %c I have also tried: login_log_format_elements = user=<%n@%d> method=%m rip=%r lip=%l %c However, this results in a log file entry of: imap-login: Login: user=<vmail@>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured How do I configure dovecot to log the _actual_ username which the client supplies during authentication? Thanks Dale

[Dovecot] Dovecot returns the same UIDL for another message
by Alexander Shikoff 23 Oct '08

23 Oct '08

Hello, I have a serious problem with dovecot and mbox format. dovecot returns the same UIDL for new messages and as result some MUAs don't retrieve new mail. UIDs returned by UIDL command look like 000000*1c*49006cec And there is a moment when dovecot stops incrementing marked digits. In other words when new message arrive to mbox, UIDL command returns used UID. I'll show with example: 1. Send some message and try to retrieve UIDL via telnet: # echo test-mailbox-1 | mail -s Test-1 mbox(a)cu.kiev.ua # telnet pop3.cu.kiev.ua 10110 Trying 193.108.130.4... Connected to emx.itcons.net.ua.

Is there some simple textual frontend to the ManageSieve protocol somewhat easier to use than gnutls-cli? I.e. something to use like managesieve -u ef putscript myscript < /tmp/myscript Password: managesieve -u ef setactive myscript Password: simply doing the TLS authentication and length computation for me.

[Dovecot] dovecot 1.0 to 1.1 upgrade and filesystem separators
by Ian Thurlbeck 23 Oct '08

Dear All I have a test system where I am trying out 1.1.4 On the old 1.0rc6 (!) system I had edited: src/lib-storage/index/maildir/mail-storage.h to change: #define MAILDIR_FS_SEP ';' #define MAILDIR_FS_SEP_S ";" so I can get some mail folder hierarchy and '.'s in folder names - this all worked perfectly. Under 1.1.4 the MAILDIR_FS_SEP lines are no longer present. What is the current practice for doing what I was doing before ? Many thanks!

Can you reproduce it? I can't really see how it's crashing. Could you apply the attached patch, and also compile the lib/*.c and lib-mail/istream-header-filter.c without -O2 so the backtrace will be more usable? (I usually do it by removing -O2 from the subdirs' Makefile and then make clean + make in those subdirs.)

Thanks Jose, Yes in the advanced options on email clients there is always a place to put the root folder path or (some similar name) and on the old server I used ~/mail/ in all of the email clients (thunderbird, outlook, seamonkey etc) and that worked fine. Doing that on the new dovecot based server produces the effect I've described - a folder called mail visible at the same level as inbox and the other IMAP folders inside that. On the older imapd based server doing the same thing produced a view of inbox with no mail folder ... just the IMAP folders in it displayed at the same level as inbox.

[Dovecot] mail_location & NFS mounted home dirs
by Roger Hale 23 Oct '08

23 Oct '08

Hi, I'm fairly new to Dovecot, migrating from a POP-only system with /var/mail only mailboxes. I'm currently on version 1.0.10 on Solaris 10, but I don't think that's relevant to the question. I'm a little overwhelmed by the number of configuration options at the moment. I took the "standard" mail_location = mbox:~/mail:INBOX=/var/mail/%u setting in dovecot.conf. This mostly works fine, but home dirs are NFS mounted and in the event that an NFS server is down users cannot read their mail. This is the case even for users who only use POP. So, my question is, do folks on this list have good suggestions for optimum ways to deal with this so that users (perhaps only POP users) can read their mail independent of home directories being available? I think I can make something up, but I'd rather take a standard approach if there is one. If this has already been discussed I apologise - just point me to it as I didn't find it.

[Dovecot] dovecot-deliver occasionally fails to deliver, leaving no clues
by Lucas Madar 22 Oct '08

22 Oct '08

Hello, I have a FreeBSD 7.1 x86 system using dovecot with postfix and a mysql user database. Everything works completely fine, except that on occasion dovecot-deliver fails. When postfix tries to redeliver the message in about 15 minutes, it succeeds. So this isn't a very big problem, just an annoying puzzle. Here's the postfix log. At first, I thought it could be a postfix delivery problem. Oct 17 00:36:22 xxxxxxx postfix/pipe[16017]: 41E581CC5B: to=<xxxx(a)xxxxx.xxx >, relay=dovecot, delay=0.04, delays=0. 01/0/0/0.03, dsn=4.3.0, status=deferred (temporary failure) I turned on delivery logging to see what I'd get, and I simply get this: deliver(xxxxxx(a)xxxxx.xxx): Oct 17 00:36:22 Info: Loading modules from directory: /usr/local/lib/dovecot/lda deliver(xxxxxx(a)xxxxx.xxx): Oct 17 00:36:22 Info: Module loaded: /usr/ local/lib/dovecot/lda/lib90_cmusieve_plugin.so (normally, here it would print out more info about the user, as "auth input" lines, but it doesn't when it fails in this way) Dovecot is not dumping core, or even printing out any error message that I can see. I have all logging turned on (except for passwords), and I still seem to get nothing. I've attached my dovecot -n output, which doesn't seem to contain the logging I have set up for deliver: log_path = /var/log/delivery.log info_log_path = /var/log/delivery.log mail_debug = yes auth_debug = yes auth_verbose = yes Any clue as to what could be going on here? Thanks, Lucas

This issue is peripherally related to the following thread Re: [Dovecot] client certs with godaddy ssl cert This is running on CentOS 5.2 with latest Atrpms for Dovecot as of this weekend. # rpm -qa | grep dovecot dovecot-sieve-1.1.5-8.el5 dovecot-1.1.4-0_81.el5 With assistance from Rainer Frey (Inxmail GmbH), I am able to successfully use client ssl certs for imap access on both my Nokia e61i and Thunderbird 2.0.0.17, problem now is dovecot sasl and postfix smtp authentication. Using the same self created CA that generates and certifies the ssl client certs in Postfix and using Dovecot SASL, I always get client didn't send proper ssl cert when trying to do a tls based smtp connection from either the e61i or tbird. Cranking up the peer debug level in Postfix, I see the connection is always rejected by Dovecot SASL eg Oct 21 16:39:07 myserver postfix/smtpd[18189]: vstream_buf_get_ready: fd 15 got 45 Oct 21 16:39:07 myserver postfix/smtpd[18189]: < mycomp.myserver.net[10.11.12.5]: AUTH PLAIN ********************************************= Oct 21 16:39:07 myserver postfix/smtpd[18189]: xsasl_dovecot_server_first: sasl_method PLAIN, init_response **************************************== Oct 21 16:39:07 myserver postfix/smtpd[18189]: vstream_fflush_some: fd 16 flush 64 Oct 21 16:39:07 myserver postfix/smtpd[18189]: vstream_buf_get_ready: fd 16 got 58 Oct 21 16:39:07 myserver postfix/smtpd[18189]: xsasl_dovecot_handle_reply: auth reply: FAIL?1?reason=Client didn't present valid SSL certificate Oct 21 16:39:07 myserver postfix/smtpd[18189]: warning: mycomp.myserver.net[10.11.12.5]: SASL PLAIN authentication failed: Client didn't present valid SSL certificate Oct 21 16:39:07 myserver postfix/smtpd[18189]: > mycomp.myserver.net[10.11.12.5]: 535 5.7.0 Error: authentication failed: Client didn't present valid SSL certificate Oct 21 16:39:07 myserver postfix/smtpd[18189]: watchdog_pat: 0x868a570 Oct 21 16:39:07 myserver postfix/smtpd[18189]: vstream_fflush_some: fd 15 flush 85 Oct 21 16:39:07 myserver dovecot: auth(default): client in: AUTH 1 PLAIN service=smtp resp=*********************************************== Oct 21 16:39:07 myserver dovecot: auth(default): PLAIN(?): Client didn't present valid SSL certificate Oct 21 16:39:07 myserver dovecot: auth(default): client out: FAIL 1 reason=Client didn't present valid SSL certificate Oct 21 16:39:07 myserver postfix/smtpd[18189]: vstream_buf_get_ready: fd 15 got 12 Oct 21 16:39:07 myserver postfix/smtpd[18189]: < mycomp.myserver.net[10.11.12.5]: AUTH LOGIN Oct 21 16:39:07 myserver postfix/smtpd[18189]: xsasl_dovecot_server_first: sasl_method LOGIN Oct 21 16:39:07 myserver postfix/smtpd[18189]: vstream_fflush_some: fd 16 flush 26 Oct 21 16:39:07 myserver postfix/smtpd[18189]: vstream_buf_get_ready: fd 16 got 58 Oct 21 16:39:07 myserver postfix/smtpd[18189]: xsasl_dovecot_handle_reply: auth reply: FAIL?2?reason=Client didn't present valid SSL certificate Not sure where to look now, I've configured dovecot and postfix as per their respective wiki's Here are the relevant config entries /etc/postfix/main.cf ### Oct 11/08 - added to allow dovecot sasl for smtp auth smtpd_sasl_type = dovecot # Can be an absolute path, or relative to $queue_directory smtpd_sasl_path = private/auth # and the common settings to enable SASL: smtpd_sasl_auth_enable = yes smtpd_recipient_restrictions = permit_sasl_authenticated, reject_unauth_destination smtpd_sasl_security_options = noanonymous ### Oct 11/08 - added to allow tls smtp authentication with client certs smtpd_tls_auth_only = yes smtp_use_tls = yes smtpd_use_tls = yes smtp_tls_note_starttls_offer = yes smtpd_tls_loglevel = 2 smtpd_tls_received_header = yes smtpd_tls_session_cache_timeout = 3600s tls_random_source = dev:/dev/urandom myhostname = server.myserver.net ### these are the self signed CA based authentication keys, this CA created ### the client certs for the nokia e61i and the Thunderbird 2.0.0.17 smtpd_tls_key_file = /etc/postfix/ssl/server.myserver.net.key smtpd_tls_cert_file = /etc/postfix/ssl/server.myserver.net.crt ### this is the ca cert and crl combined smtpd_tls_CAfile = /etc/postfix/ssl/ca1.crt dovecot -n # 1.1.4: /etc/dovecot.conf protocols: imaps pop3s ssl_listen(default): *:993 ssl_listen(imap): *:993 ssl_listen(pop3): *:995 ssl_ca_file: /etc/openvpn/easy-rsa/keys/combined-ca-and-crl.crt ssl_cert_file: /etc/pki/dovecot/certs/dovecot-chained.cert ssl_key_file: /etc/pki/tls/private/server.myserver.net.key ssl_verify_client_cert: yes ssl_require_client_cert = yes verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_location: mbox:~/mail:INBOX=/var/spool/mail/%u:INDEX=~/mail/.imap/indexes mail_debug: yes mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 auth default: mechanisms: plain login debug: yes debug_passwords: yes ssl_require_client_cert: yes passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix Interestingly enough the mode line in the dovecot.conf file is set as 0660, not 432 as noted above?!?!?

[Dovecot] dovecot delivery log
by jalal 22 Oct '08

22 Oct '08

Trying to debug a delivery problem recently (with Postfix) and I realized that Dovecot wasn't logging any of the delivery information. I'm using Postfix to recieve mail, which is passing it on to Dovecot's deliver to actually deliver the emails into the mail boxes. In dovecot.conf, I have: protocol lda { log_path = /var/tmp/dovecot-deliver.log } [root]# dir /var/tmp/ total 2 drwxrwxrwt 2 root root 1024 Oct 22 12:30 . drwxr-xr-x 24 root root 1024 Aug 5 08:03 .. -rw------- 1 vmail vmail 0 Oct 22 12:11 dovecot-deliver.log The log file gets created OK, but then stays at zero size. Using: Postfix 2.3.3 Dovecot 1.1.4 (and previously 1.0.9) Any clues as to how I can have a delivery log?

[Dovecot] displaying IMAP folders that are in ~/mail/ at same level as inbox
by David London 22 Oct '08

22 Oct '08

Hi, We are moving our current IMAP based system to a new one with dovecot All I can get about the current IMAP (imapd) system is: IMAP4rev1 v12.264 dovecot version is: 1.0.rc15 In the existing system I can see IMAP folders that are in ~/mail/ with many mail clients (e.g. Thunderbird, Outlook, Seamonkey and horde). These folders are presented in the client software as being at the same level as the inbox - i.e. not inside the folder "mail" On the new system, horde webmail shows the other folders in ~/mail/ as being at the same level as the inbox. But ... all the other mail clients above now show a folder (directory) called mail with the imap folders inside. Is there some way to set this up so these other mail clients see the imap folders in ~/mail/ as being at the same level as the inbox as we have on the old server? Thanks, David _________________________________________________________________

[Dovecot] Permission issues with subscriptions
by Eric A. Bonney 22 Oct '08

22 Oct '08

I am having some permission issues with my setup and I can't see where to make the change in the configuration files. My users can not create folders at all from their email clients nor from the web interface. I have noticed that each time I try to create a folder the subscriptions files permissions are set to 000. If I go back and reset the permissions to rw-r--r-- then everything is fine until I try to add another folder. running dovecot -n produces the following: # 1.0.10: /etc/dovecot/dovecot.conf listen: [::] login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login verbose_proctitle: yes first_valid_uid: 1000 default_mail_env: maildir:/mnt/hd4/MailBoxes/%d/%n mail_location: maildir:/mnt/hd4/MailBoxes/%d/%n umask: 511 auth default: user: nobody passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: prefetch I am guessing that Dovecot is the actual process that is creating the folders on the IMAP server, so where inside the configuration file do I set the permissions for the new folders along with the user and groups? Thanks, -Eric

[Dovecot] Proxying pop3 sessions into an imap one.
by Diego Liziero 22 Oct '08

22 Oct '08

I know it seems at least unusual. But I would like to know if someone knows a software that can proxy multiple pop3 and imap connections to the same account and use only imap connections to the real server. I need it because I've to deal with two pieces of software that are out of my control: - 1 - A certified mail provider that states something that I would like to know if it's really true, or if it's worth keeping like a funny signature: "multiple imap sessions are possible. When an imap session is active, no pop3 connections are possible on the same account; when no imap connection is active, only one pop3 connection at a time is possible on the same account. This is a limitation of the pop3 protocol." - 2 - A software written to deal with certified mails that supports only pop3 used by many people on the same account, (and the same account is used also by multiple imap mail readers). Regards, Diego.

[Dovecot] 1.2: Bug in listing of shared mailboxes with dot in user id

In dovecot 1.2 I can create a shared name space like this: namespace shared { separator = / prefix = users/%%u/ location = Maildir:/PATH/TO/spool/%%u/maildir:INDEX=/PATH/TO/spool/%u/maildir/shared_idx subscriptions = no } now, when I subscribe to a shared mailbox of another user with an dot in the users id, like: users/2(a)example.com/INBOX/foo and I list my subscribed mailboxes I get: l001 lsub "" "*" * LSUB () "/" "users/2@example/com/INBOX/foo" as you can see the dot in the user-id got normalized to the hierarchy seperator `/' -- which of cause is wrong. ;-) cheers sascha -- Sascha Wilde OpenPGP key: 4BB86568 http://www.intevation.de/~wilde/ http://www.intevation.de/ Intevation GmbH, Neuer Graben 17, 49074 Osnabrück; AG Osnabrück, HR B 18998 Geschäftsführer: Frank Koormann, Bernhard Reiter, Dr. Jan-Oliver Wagner

[Dovecot] Reporting NFS quotas via IMAP
by Edgar Fuß 21 Oct '08

21 Oct '08

I'm confident that the question has been asked before, but I can't remember the answer. I have -- dovecot 1.1.2 -- Mail storage (maildir format) on NFS -- Quotas on that file system -- A working rquotad -- mail_plugins = quota imap_quota in the protocol imap section -- quota=fs in the plugin section I get (using Apple Mail as a client) -- Notification that the account supports quotas -- No information about the size of the quota nor the usage I probably do something stupidly wrong. The WIKI tells me that fs quota support RPC (i.e., rquotad), so I'd expect my client to report the quota to me. Using quota(1) on the mail server works as expected.

[Dovecot] Using allow_nets
by Guy 20 Oct '08

20 Oct '08

Hi, I'm wanting to implement allow_nets so that some users can be limited to only use webmail while others can use client or webmail access. Adding the sql to pull a list of IPs/ranges for webmail only users was easy enough. For the users that are allowed to access from anywhere, do I need to specify 0.0.0.0/0 or something or can I just let the sql query return a blank field? Thanks Guy -- Don't just do something...sit there!

[Dovecot] v1.1.5 release candidate
by Timo Sirainen 20 Oct '08

20 Oct '08

http://dovecot.org/tmp/dovecot-1.1.5-rc.tar.gz I thought about making v1.1.5 release today, but then thought maybe I'll make an RC instead since I did quite a lot of changes this weekend. So please try and see if there are any bugs left. I'll make the final release in a couple of days. The largest changes since v1.1.4: + Maildir/dbox: Try harder to assign unique UIDVALIDITY values to mailboxes to avoid potential problems when recreating or renaming mailboxes. The UIDVALIDITY is tracked using dovecot-uidvalidity* files in the mail root directory. + Many logging improvements - In some conditions Dovecot could have stopped using existing cache file and never used it again until it was deleted. - pop3 + Maildir: Make sure virtual sizes are always written to dovecot-uidlist. This way if the indexes are lost Dovecot will never do a huge amount of work to recalculate them. - mbox: Fixed listing mailboxes in namespaces with prefix beginning with '~' or '/' (i.e. UW-IMAP compatibility namespaces didn't work). - dict quota: Don't crash when recalculating quota (when quota warnings enabled). - Fixes to handling "out of disk space/quota" failures. - Fixed compiling with OpenBSD

[Dovecot] NFS quota: hard or soft
by Edgar Fuß 20 Oct '08

20 Oct '08

Yes. I could spend more time testing this myself or examining the code. It looks to me that, with fs quota, dovecot refuses to store a mail (e.g. when the client moves a mail from one IMAP folder to another) if the user is beyond his soft limit. Is this correct/intended? Knowing nothing about the IMAP Quota extension, I would have expected that being in grace was OK. At least, this is what would happen if dovecot wasn't quota aware and the file system would enforce the limits.

[Dovecot] Sendmail and deliver LDA exits with EX_TEMPFAIL on overquota
by Sotiris Tsimbonis 20 Oct '08

20 Oct '08

Hi all, I have setup dovecot 1.1.4 and sendmail 8.14.3 with dovecot LDA on linux (RHEL5 on x86_64). I have deliberately set a very low quota (4MB) on a test account, while the actual disk usage is 5MB at the moment, in order to test overquota behaviour.. When I send an email to this account, sendmail accepts the email and tries to deliver it. Deliver fails to save in INBOX and returns an error, but the email stays in sendmail's queue.. Any suggestions on how to avoid this and produce a 5xx error for overquota users before accepting the email would be greatly appreciated..

[Dovecot] workaround for shared maildirs
by Giuliano Gavazzi 19 Oct '08

19 Oct '08

Hello, this is my first post to the list. I have several mailservers running courier-imap, but am planning to convert one (and maybe more) to dovecot 1.1.4. In the process I am also looking to finally implement shared maildirs. As it is well known some clients (notable Apple's Mail) have problems in showing shared folders if the correct private namespace (INBOX) is set in the client, as only folders beneath the INBOX root are displayed. I have seen some solutions proposed, but none satisfactory. As the problem stems in the invisibility of secondary namespaces from Mail.app, I though that tricking the namespace prefix to push the shared mailboxes inside the private INBOX namespace could be a solution and tried the following: namespace public { separator = . prefix = INBOX.Public. inbox = no location = maildir:/SharedMaildirs/Public:CONTROL=~/Maildir/ control/Public:INDEX=~/Maildir/index/Public hidden = yes list = yes subscriptions = yes } note the bogus INBOX.Public prefix. Note also that CONTROL might be better not set as this is a Maildir (see Keyword sharing in http://wiki.dovecot.org/SharedMailboxes) Initially I had defined an additional public namespace with the same maildir and a normal prefix, but this seems not necessary. Well, after some tests from Thunderbird, Mail and cone (yes, the courier UA) I can say it works . Still have to check Outlook and Opera, but this is encouraging. As the public namespace Public is actually contained inside the private (INBOX), as if it was a private mailbox (with no messages) called Public, it is actually possible to create such a mailbox inside INBOX and end up with a private mailbox called Public containing private messages AND public mailboxes... Any mailbox that a user creats inside Public instead, will end up being a public mailbox as expected. Thanks or any comments. Giuliano

[Dovecot] regarding dovecot.index.cache
by Dhaval Thakar 19 Oct '08

19 Oct '08

Hi, This is regarding updating dovecot.index.cache. I have few backup ids configured. these are used only when old mail needs to be retrieved. usually these mailboxes contains more then 9,000 mails. while login to webmail, imap consumption is high, which creates performance related issues for regular mailboxes. to resolve this i have to move heavy mailbox to dedicated server. before doing that, I wanted to confirm if there any way to update dovecot.index.cache even if user is not checking his / her mails. kindly confirm, & provide direction to implement same. Following is the mailserver related details Qmail with Vpopmail 5.4.24 Dovecot-1.1.4 dovecot -n # 1.1.4: /etc/dovecot/dovecot.conf protocols: imap ssl_disable: yes disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login mail_plugins: quota imap_quota trash imap_client_workarounds: delay-newmail outlook-idle namespace: type: private prefix: INBOX. inbox: yes list: yes subscriptions: yes auth default: mechanisms: plain login verbose: yes debug: yes debug_passwords: yes passdb: driver: checkpassword args: /home/vpopmail/bin/vchkpw userdb: driver: vpopmail userdb: driver: prefetch plugin: quota: maildir quota_rule: Trash:ignore thanks & regards dhaval

[Dovecot] Dovecot 1.1.4 / Maildir++ quota and move to trash
by Xavier Beaudouin 18 Oct '08

18 Oct '08

Hello, Seems there is some nasty problems with Dovecot 1.1.4... We use Maildir++ quota, and when moving mail to Trash, Dovecot just drop the connection... when the maildir is overquota. Is there any way to avoid that and just move the mail to the trash allowing user to expunge their mail easily without calling support to do rm -rf Maildir/cur ? Thanks, /Xavier

Although the first login fails, >the next one should succeed. Yes, that's right. I didn't realize it at first, because we were also seeing other problems (eg assertion failure at line 39 of index-sync.c) which did require the index to be deleted. I've since made the following changes: 1) commented out the assertion at line 39 of index-sync.c (as per http://www.nabble.com/dovecot-panic-after-upgrade-1.0.15-to-1.1.2-td1909850…) 2) recompiled dovecot without optimization (ie, gcc -O0 instead of -O2) (as per http://www.mail-archive.com/dovecot@dovecot.org/msg12936.html) 3) reverted to using flock for file locking instead of fcntl (we'd been using flock with dovecot 1.0.10; 1.1.3 used fcntl by default in a couple of places, so I changed it back to see what would happen) After this, we've seen fewer problems, but there are still the occasional ones: - the original corrupted transaction log error which prompted this thread - we still see the occasional assertion failure at line 1091 of index-mail.c; this is the one that I'd hoped to solve by recompiling without optimization, but at least it seems to be happening less frequently than before - this doesn't happen often, but once in a while we see assertion failures at line 163 of src/pop3-login/client-authenticate.c or line 200 of src/imap-login/client-authenticate.c >Can you reproduce this by running imaptest (on a test account)? >http://imapwiki.org/ImapTest Actually this and your other suggestions may not be necessary; I think I just realized what's been going on.

For example, Oct 3 17:52:21 alcor dovecot: imap[14973] XXXX, NNN.NNN.NN.NNN: Corrupted transaction log file /home/XXXX/mail/.imap/sent-mail/dovecot.index.log: record size too small (type=0xcd91, offset=8180, size=0) Oct 3 17:52:21 alcor dovecot: imap[14973] XXXX, NNN.NNN.NN.NNN: fscking index file (in-memory index) Oct 3 17:52:21 alcor dovecot: imap[14973] XXXX, NNN.NNN.NN.NNN: Transaction log got desynced for index (in-memory index) Oct 3 17:52:21 alcor dovecot: imap[14973] XXXX, NNN.NNN.NN.NNN: Disconnected: IMAP session state is inconsistent, please relogin. bytes=169/1848 Oct 3 17:52:22 alcor dovecot: imap-login: Login: [14998], XXXX, NNN.NNN.NN.NNN Oct 3 17:52:22 alcor dovecot: wrapper[15023]: imap, XXXX, NNN.NNN.NN.NNN Oct 3 17:52:22 alcor dovecot: imap[15023] XXXX, NNN.NNN.NN.NNN: open(/home/XXXX/mail/.imap/CFI-Howe/.temp.alcor.15023.e786c194b1dcc08c) failed: Disk quota exceeded Having seen this, I went back to the saved log for September 30th (the one containing the excerpt I pasted into my original message in this thread) -- and interestingly, I found that the quota failure wasn't recorded there. I don't know what was different about that occurrence, but everything I've seen recently suggests that "record size too small" is due to interaction with the quota system. ...so this is where I admit that I have indeed read http://wiki.dovecot.org/Quota/FS; unfortunately, the only user-writable file system on this machine that doesn't have (or need to have!) disk quotas enabled is /var/tmp, which doesn't seem to be a suitable place for dovecot indexes. Under the circumstances, are you still interested in seeing ImapTest results and a backtrace? If so, should I do that before or after upgrading to 1.1.4?

[Dovecot] Request for help with new plugin
by John Lightsey 18 Oct '08

18 Oct '08

Hi there, I was having lots of trouble with the normal expire plugin so I decided to try and come up with a plugin that handles the trash directory in the same way as Courier (when the user logs out it should clean messages from the trash that have been there for more than X days.) I used the expire and trash plugins as a guide but there are probably a number of things done wrong here and I have plenty of questions. To use this you'd need to run autoreconf for the autotools scripts, compile, make, make install, then add "autoexpire" to the imap/pop3 mail_plugins lists and "autoexpire = Trash 7" to the plugin section. 1. Is there any documentation of how the hook system and virtual mailboxes work outside of the source code? 2. I'd like the Trash cleanup to occur at logout, but the closest I could find was mailbox close. This makes the behavior a little quirky. It seems like Dovecot closes the mailbox each time it performs an operation on it, so when the client gets a list of mail in the box it does a close and the oldest items in the returned list will actually be expunged. 3. Is SAVE_DATE the correct field to be looking for here? I want the expiration to be based on the amount of time the letter has spent in the trash folder. 4. For searching through the Trash folder, SEARCH_BEFORE doesn't seem to match up with SAVE_DATE. Is there some other way to limit the search results to the dates that will fall before a certain SAVE_DATE value? J.D.
