[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

[Dovecot] Indexes recovery failed

Hi Timo, Was getting the following error repeatedly in my mail client (squirremail) "error: connection dropped by IMAP server" Looked at the logs for this user and found the following: Nov 19 17:11:32 mink dovecot: IMAP(bobuser(a)maildom.com): broken sync positions in index file /virtual/store2/mail/s/bobuser_maildom.com/Maildir/dovecot.index Nov 19 17:11:32 mink dovecot: IMAP(bobuser(a)maildom.com): fscking index file /virtual/store2/mail/s/bobuser_maildom.com/Maildir/dovecot.index Nov 19 17:11:32 mink dovecot: IMAP(bobuser(a)maildom.com): Fixed index file /virtual/store2/mail/s/bobuser_maildom.com/Maildir/dovecot.index: log_file_tail_offset 2273345664 -> 996 Nov 19 17:11:32 mink dovecot: Panic: IMAP(bobuser(a)maildom.com): file mail-transaction-log.c: line 341 (mail_transaction_log_set_mailbox_sync_pos): assertion failed: (file_offset >= log->head->saved_tail_offset) Nov 19 17:11:32 mink dovecot: IMAP(bobuser(a)maildom.com): Raw backtrace: imap [0x46c772] -> imap [0x46c7e3] -> imap [0x46be56] -> imap [0x452d6d] -> imap(mail_index_sync_commit+0x42) [0x44e022] -> imap(maildir_sync_index_finish+0xdd) [0x42b59d] -> imap [0x42ada1] -> imap(maildir_storage_sync_init+0x64) [0x42af44] -> imap(mailbox_sync+0x1c) [0x43e96c] -> imap(cmd_select_full+0xce) [0x41a2be] -> imap(cmd_select+0xb) [0x41a44b] -> imap [0x41bb7c] -> imap [0x41bc32] -> imap [0x41c3ff] -> imap(client_input+0x63) [0x41c633] -> imap(io_loop_handler_run+0xf8) [0x472ed8] -> imap(io_loop_run+0x1d) [0x471ffd] -> imap(main+0x3c2) [0x423a92] -> /lib/libc.so.6(__libc_start_main+0xf4) [0x7f29213711c4] -> imap [0x416349] Looks like dovecot tried to fix the indexes but failed. I manually deleted all the dovecot.index* files and the account started working. Perhaps dovecot could try the fix but if it still fails just go and delete the indexes itself? Dovecot version 1.1.6 Using Maildirs Over NFS mount If you need any more info just let me know. Regards, Daniel

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

[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] 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.

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.

[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?
by Rob Nichols 21 Nov '08

21 Nov '08

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] 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
by sleeper-＠gmx.net 19 Nov '08

19 Nov '08

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.

[Dovecot] Mail.app & Subscriptions
by Neil 19 Nov '08

19 Nov '08

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
by Fredrik Grönqvist 19 Nov '08

19 Nov '08

Hi, I've searched in the wiki and in the mailinglist archives but haven't found anything about password character sets within the dovecot authentication deamon. My problem is that we have users with passwords containing scandinavian characters (äöå, umlauts) and the debug log shows that different clients send the password in different charsets. The passwords are stored in a Mysql table, if that makes any difference.

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.

[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!

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.

[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

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).

[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

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] ocfs2 dovecot
by Robert Schetterer 10 Nov '08

10 Nov '08

Hi Timo, in the wiki there is only talked about gfs filesystem are there any known breaking problems using ocfs2 with dovecot ? in my vmware setup ocfs2 seems to be more debian/ubuntu config friendly like gfs dont got gfs to run, perhaps this might be better on suse/centos/redhat but i simply want to use ubuntu hardy server version -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

[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

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

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] problem with i_stream_next_line()

Hello there, I have a "subscriptions" file that is *not* ended with a line break (created by another system). When I do a "lsub "" "*"" the last mailbox name is not listed. Debugging a little showed that it looks like i_stream_next_line() is not returning the last line if it doesn't end with a line break. Is this a bug? btw, i'm using version 1.1.6. []'s

[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.

Does the log show that the incoming messages are actually received? If not, it sounds like you're missing an MX record in DNS. If you are seeing the message come in, what does the log say it did with it? - Jon On Nov 2, 2008, at 1:45 PM, mailing wrote: > > I am using Postfix and /var/logs/mail.log does not have any errors > when > sending to lemcoe.com > > Thanks for quick response. > > On Sun, 2 Nov 2008 13:41:31 -0700, Jon Fullmer <jon(a)jonfullmer.com> > wrote: >> What are you using as your MTA (i.e., which server is listening for >> the incoming SMTP message)?

[Dovecot] Issue with domains
by David M Lemcoe Jr. 02 Nov '08

I am running Dovecot 1.0.10 and have it working great on ender.ath.cx (my free DynDNS.com subdomain), but recently I registered lemcoe.com and pointed it to the same IP address as ender.ath.cx. The problem is, only e-mail sent to the @ender.ath.cx works. If it is send it to @lemcoe.com, I don't know where it goes. I get no errors either. How can I get Dovecot to recognize both domains? TIA.

[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] 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.
