[Dovecot] File and group permissions for incoming mails
by Sascha Scandella 02 Apr '09

02 Apr '09

Hello I am using Dovecot 1.1.1 together with Postfix (and for some users Procmail for Spam Filtering). Until now I didn't have to use shared mailboxes. Now I want to use simple simlinking to grant other users of the same group access to my mails. The problem is that new incoming mails have always file permissions set to 0600. I have also a file called dovecot-shared (0660) in the Maildir folder. No success. Why doesn't this work? I also tried to use UMASK in the procmailrc. No success. Any help is appreciated! Best regards Sascha

[Dovecot] dbox - how to awaken the monster
by Odhiambo Washington 02 Apr '09

02 Apr '09

Hello people, Since the invention of this storage called dbox, I have never quite gotten round to understanding it, nor getting to use it. It seems so strange to me and I must ask a few stupid questions about it. I use the MTA to deliver mail to Maildir, either in ~/Maildir or /some/path/%d/%n/Maildir. It has always beat me how dbox comes into play under such circumstances. From the wiki, I see the following: "dbox supports a quick migration from Maildir format" - now this leaves me hanging. How? Suppose I migrate from Maildir to dbox, what changes do I make to the MTA to understand that I use dbox? Ok, I use Exim as my MTA. I hope someone can explain to me what I need to do to Exim and what to do th Dovecot so that I can test this dbox thing. And suppose I want to transfer userA's mail to UserB, what do I do? With Maildir, I can simply do something like mv ~A/Maildir ~B/Maildir chown -R B ~b/Maildir Suppose I am using dbox, howdy? Thank you in advance. I know those sound dumb, but I simply haven't understood dbox. -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ "The only time a woman really succeeds in changing a man is when he is a baby." - Natalie Wood

[Dovecot] Dovecot in OSCON 2009?
by Timo Sirainen 02 Apr '09

02 Apr '09

Hi, I'm thinking about attending OSCON 2009 with some other people from Mailtrust and having some kind of an informal Dovecot meeting nearby. We could for example talk about what Dovecot would need to work better in your system, like missing features or if some things are annoyingly difficult etc, or just general talking and socializing. If you're interested in joining, send me a mail (privately, unless you have something else to say besides "yes").

[Dovecot] Slightly OT : Maildir format (silly) questions
by Thomas Hummel 01 Apr '09

01 Apr '09

Hello, I was asking what was the motivation for not having the envelope From in the Maildir format, as defined in the qmail spec : "The message is delivered without an extra UUCP- style From_ line, without any >From quoting, and without an extra blank line at the end." which may sound silly since we lose an important piece of information. Same question about the motivation in Courrier (Maildir++) for emulating a hierarchy for subfolders (like in .folder.subfolder.subsubfolder) instead of (note : I know about layout=FS, I'm not talking about that) implementing a real filesystem hierarchy. I understand dovecot kept those for compatibility reasons but I'd like to know what was the authors of thoses specs thinking when deciding this.

[Dovecot] Informations in LDAP and Database
by Etienne MAYNIER 01 Apr '09

01 Apr '09

Hi everybody, I'm installing an application using LDAP and I want dovecot to use LDAP too. The problem is that they don't use the same schema (especially because we want per-user quotas). I think the best solution is to have the authentication by LDAP and others datas (like quotas) in a database. Is it possible with dovecot ? and How ? Thanks Etienne

Hi, I'm testing migration from courier to courier-0.57.0 to dovecot-imap-1.1.12 on a debian/sid box. When running the migration script, non of the active users' "courierimapsubscribed" and "courierimapuiddb" files seem to be detected: ZENON:~# ./courier-dovecot-migrate.pl --to-dovecot --recursive /home Testing conversion to Dovecot format Finding maildirs under /home /home/XXXX/Maildir: No imap/pop3 uidlist files /home/XXXX/CB: No imap/pop3 uidlist files /home/XXXX/Maildir/subscriptions already exists, not overwritten /home/XXXX/Maildir: No imap/pop3 uidlist files /home/XXXX/Maildir: No imap/pop3 uidlist files /home/XXXX/Mail: No imap/pop3 uidlist files /home/XXXX/Maildir: No imap/pop3 uidlist files /home/XXXX/Maildir: No imap/pop3 uidlist files Total: 0 mailboxes / 0 users 0 mailboxes / 0 users 0 errors No actual conversion done, use --convert parameter (the /home/XXXX users are old, non-active users) However when trying the courier-dovecot-migrate-1.0.pl I get plenty of mailbox matches, but since I am installing 1.1.12 it is useless to me.

[Dovecot] about quota in dovecot
by guojinpeng(郭晋鹏) 01 Apr '09

01 Apr '09

Hi, I’m currently try to use the dovecot quota plugin. I use the maildir plugin ,and use mysql as to get the quota rule.

[Dovecot] ampersand in local-part

I have a new email server (postfix/dovecot/mysql) with accounts migrated from another server (different platform) and email addresses with ampersands like "r&d(a)domain.com" that worked on my old email server are not working now.

[Dovecot] dbox with non-dovecot LDA
by Justin Krejci 01 Apr '09

01 Apr '09

Aside from the code is there any documentation on using dbox with a non-Dovecot LDA? We have our own MTA and currently use Dovecot with Maildir only for message retrieval and just have our MTA write the message files to our own directory structure (Dovecot per user mailbox locations stored in mysql) but I am interested in looking at moving to dbox if it is better for performance and other things like static filenames. One thing we'd like to do is not use the Dovecot LDA so as to control the entire inbound email delivery process all the way to verifying the actual message is 100% written to disk. Certainly we can use the Dovecot LDA if it came to it but we'd like to retain control over this entire process if possible.

[Dovecot] Virtual user folder configuration
by Daniel L. Miller 31 Mar '09

31 Mar '09

Since I'm going to make a change to my folder structure, what would be recommended so I can avoid the need in the future? All my mail users are virtual - they have no existence in /etc/passwd, nor do they have folders under /home. At this time, all mail is being delivered to maildir:/var/mail/%d/%n - and the home is the same (which is becoming more of a problem). As I see it, I have the choices of: 1. Place mail underneath home, as in /var/mail/%d/%n/mailbox Probably the simplest, but adds a level to the folder hierarchy. Does that matter in any way? 2. Place home underneath mail, as in /var/mail/%d/%n/home (unless THAT poses a problem as well, with a non-mail folder visible to the mail system) Leaves mail alone - but means the home folder is visible from within the mail system. 3. Relocate home totally outside mail, as in /var/mail/home/%d/%n Would provide isolation - but more difficulty in administration, particularly adding/deleting users. Any suggestions? -- Daniel

[Dovecot] CMUSieve with virtual users
by Guillaume HILT 31 Mar '09

31 Mar '09

Hi, I'm using dovecot 1.1.7 on Gentoo with Postfix and PostfixAdmin to manage my virtual users. I'm trying to use sieve (which has been compiled with Dovecot) but it doesn't work. I added cmusieve in the lda protocol : mail_plugins = cmusieve mail_plugin_dir = /usr/lib/dovecot/lda My maildir scheme is : /home/vmail/%d/%n/.maildir The sieve file is in /home/vmail/%d/%n/.dovecot.sieve (i'm using the sieve variable in the plugin section). I also tried in /home/vmail/%d/%n/.maildir/.dovecot.sieve. Then I tried in /var/sieve-scripts/%u.sieve. None of these solutions worked :x I enabled all the debug options in dovecot, and i can't see anything about sieve in my logs. I'm using the same configuration without virtual users on another server and it's working fine. I'm out of ideas. Could someone has managed to use sieve scripts with virtual users ? Thanks :) Guillaume

[Dovecot] Sieve Rule for Folders
by Gerhard Wiesinger 31 Mar '09

31 Mar '09

Hello! Is it possible with sieve to do the following: When a new message is added to a folder (e.g. dovecot folder and not INBOX) then an action like forwarding it per E-Mail should be triggered. Is this possible? If yes, how does the sieve script look like? If possible, can a shell script also be triggered as action? Thanx. Ciao, Gerhard -- http://www.wiesinger.com/

[Dovecot] Empty To: Header and message_address_parse
by Wolfgang.Friebel＠desy.de 31 Mar '09

31 Mar '09

Using dovecot 1.2beta (but earlier versions should behave similarly) we have a problem in conjunction with empty To: headers and the RT request tracker. RT sends mail out using Bcc: and no To: header at all. To make some mailers happy one can configure to send a dummy To: header, which we do. Our To header looks like: To: "AdminCc of rt Ticket #123456":; The message_address_parse function called with the TRUE flag (triggers add_fixed_address) in dovecot changes that to To: AdminCc of rt Ticket #123456: MISSING_MAILBOX@MISSING_DOMAIN ; and then at least alpine does use that invalid address as Cc: address when replying. If the mail is stored in a local folder, i.e. does not get fetched via IMAP then the To: line is displayed as is and a reply does not result in an errorneous Cc: This behaviour is at least inconsistent from a user point of view. Is there some advice other than change the RT mail header generation? (other mailers seem to copy the To: line unaltered which results in an invalid address as well, therefore I admit that the real problem is with RT) -- Wolfgang Friebel Deutsches Elektronen-Synchrotron DESY Phone/Fax: +49 33762 77372/216 Platanenallee 6 Mail: Wolfgang.Friebel AT desy.de D-15738 Zeuthen Germany

[Dovecot] Convert from maildir to dbox
by Daniel L. Miller 31 Mar '09

31 Mar '09

Ok...I made the leap. Compiled a copy of 1.2b4 (very pleasant compile BTW - almost no warnings, nice code Timo!)...tweaked a config...had a few false starts... 1.2b4 seems to working quite nicely. Now...for my next magical trick... I would like to migrate from maildir to dbox. I've tried using the convert plugin, but it kept failing during the conversion. I should mention my paths: home (old & new) = /var/mail/%d/%n old mail = maildir:/var/mail/%d/%n new mail = dbox:/var/mail/%d/%n/dbox Note that "home" was defined as the same path as "mail" in my old config - I'm looking to fix that as well during the migration. I found entries in my mail log after the convert execution similar to: Mar 30 19:00:52 bubba dovecot: IMAP(sfox(a)amfes.com): rename(/var/mail/amfes.com/sfox/.dovecot.convert.lock/cur, /var/mail/amfes.com/sfox/dbox/mailboxes/dovecot/convert/lock/dbox-Mails) failed: Not a directory Mar 30 19:01:41 bubba dovecot: IMAP(sfox(a)amfes.com): Mailbox conversion failed for mailbox dovecot.convert.lock Now that I'm staring at that line...I'm wondering if that "home=mail" configuration is part of the problem. I currently have about a dozen users on this box - but with very large mailboxes (I still have archived mailing lists in mine!). If there's a few manual steps I need to perform to "condition" this setup prior to conversion please advise. Should I manually shift the mailboxes into a "/var/mail/%d/%n/maildir" folder? -- Daniel

[Dovecot] MAILBOXDIR question
by Stewart Dean 31 Mar '09

31 Mar '09

I'm unclear about where and how this is to be used. I gather it is to be a new standard, but I didn't seem to find anything about it in the Dovecot Wiki Mail Location page. There are some words about it in the 1.1.12/3 release notes, but perhaps I'm thick, but they're meta-ambiguous to me. Is it meant to be used like this: mail_location = mbox:MAILBOXDIR=~/mail:INBOX=/var/mail/%u instead of the current mail_location = mbox:~/mail:INBOX=/var/mail/%u ??? Sorry to be so dense. -- ==== Once upon a time, the Internet was a friendly, neighbors-helping-neighbors small town, and no one locked their doors.

[Dovecot] Panic: Trying to allocate 2147483648 bytes
by David Halik 30 Mar '09

30 Mar '09

Hi all, I recently upgraded from courier to dovecot 1.1.12 on a Solaris 9 system with about 100 users. We have been testing dovecot for sometime in a mixed Linux/Solaris environment and are aware of the index endianess issue with multiple archs. To solve this, we run with INDEX=MEMORY (as seen in the docs) so that only Linux clients have anything to do with the indexes. We generally have much more of them anyways. So far everything is working smoothly, but when someone does a search through directory with a large number of emails, dovecot dies and prints the following message: [ID 107833 mail.crit] Panic: Trying to allocate 2147483648 bytes I googled around and saw this same issue elsewhere, with NFS indexes usually being the problem. However, we have indexes turned off, so I don't understand why the same problem is still happening. Just to be sure, I ran with: mmap_disable = yes dotlock_use_excl = no mail_nfs_storage = yes But there has been no change, I can still reproduce it at will. Setting mail_nfs_index = yes caused my connections to stop working, so that didn't help either. Besides, I wouldn't think that would be the answer considering we set INDEX=MEMORY. This thread also seems to be related, but we're definitely running with this code in 1.1.12, yet it still happens: http://dovecot.org/list/dovecot/2008-September/033615.html I grabbed a backtrace if it is helpful: http://pastebin.com/f5f3d282c Also, here is dovecot -n: # 1.1.12: /usr/local/etc/dovecot.conf # OS: SunOS 5.9 sun4u protocols: imap imaps pop3 pop3s ssl_cert_file: /usr/local/ssl/certs/nbcs.key+crt.pem ssl_key_file: /usr/local/ssl/certs/nbcs.key+crt.pem login_dir: /usr/local/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_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no mail_location: maildir:~/Maildir:INDEX=MEMORY mmap_disable: yes mail_nfs_storage: 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 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 pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): UID%u-%v namespace: type: private separator: . prefix: INBOX. inbox: yes list: yes subscriptions: yes auth default: passdb: driver: pam args: * userdb: driver: passwd plugin: quota: fs Any help would be appreciated!

[Dovecot] Upgrade from 1.0 to 1.1, plus migration from Maildir to dbox
by Daniel L. Miller 30 Mar '09

30 Mar '09

Ok - I gave up on trying to get CIFS to work - there's obviously stuff going on I don't understand. So - instead of trying to get a virtual server to work, I next tried a chroot. That worked...but imapsync error'ed out trying to handle one of my large mailboxes. I was trying to setup a "new" server, migrate all my mail over, verify everything worked - maybe even leave the virtual server operating for a while. But the fates are consipiring against me. So - time to make the leap. I want to upgrade a live version 1.0 server to version 1.1 (from Ubuntu repositories, using version 1.0.10 to 1.1.4). What special steps do I need to take to have this go smoothly? At least I have some semi-tested configs for 1.1 that I can use. Do I just stop the server, upgrade, upgrade the configs, start - and pray? Or is there another step? Also, my legacy installation was using maildir - I'd like to try shifting to dbox. Do I just need to change the prefix on mail_location and the conversion will magically happen? -- Daniel

[Dovecot] dovecot: auth(default): ldap(...): Authenticated user not found
by Stas SUSHKOV 29 Mar '09

29 Mar '09

Hi, I'm trying to set up dovecot together with postfix and experience some problems. Here's in details what I have and what I want to get. I have a ldap server on localhost, a working setup of dovecot to serve sasl, imap using ldap, a working setup of Postfix for (s)smtp (I can authenticate which uses dovecot's sasl). What i wan't to get is a completely working email server for ldap users with their email forwardings (so far they have only 1 forwarding). The porblem I stuck on is the following: when sending mail through (s)smtp, after passing authentication, I get my email dropped. And I see this in logs: http://ciorne.softwareliber.ro/index.php/view/raw/aaf3eb42 ***Authenticated user not found!!!*** My dovecot conf is this: http://ciorne.softwareliber.ro/index.php/view/raw/f8696531 And my dovecot-ldap is this: http://ciorne.softwareliber.ro/index.php/view/raw/698dc851 (I'm using prefetch) Can somebody point me where's my problem. *Any* advices are welcomed!!! Thank you in advance. P.S.: Environment is a vanilla installation of Ubuntu 8.04.02 with latest updates. -- () Campania Panglicii în ASCII /\ http://stas.nerd.ro/ascii/

[Dovecot] sendmail with dovecot sasl
by Mario Pavlov 28 Mar '09

28 Mar '09

Hi, I was wondering if I can make sendmail use dovecot's SASL implementation...maybe I should somehow compile it against dovecot's SASL ? My idea is to make sendmail and dovecot authenticate against one central user/password repository. Is this possible ? thank you. P.S. I want to use virtual users

Hi, Is there a way for dovecot to use a pool of sql (mysql) servers and load balance queries between these? Also fallback to next available sql server if connection to previous one fails. Can dovecot do such things currently? (If not this is feature request). -- Arkadiusz Miśkiewicz PLD/Linux Team arekm / maven.pl http://ftp.pld-linux.org/

[Dovecot] Making changes to dovecot log levels
by Thomas M Goerger 27 Mar '09

27 Mar '09

Hi Timo, Not sure if you saw this yet, or if you're still working on a response. Awhile back I'd written about making changes to some of the log levels that dovecot writes to to stop the process from writing these to monitor. I wanted to run a few changes by you for this, just to make sure these won't cause problems somewhere else. And to send this to the list, in case anyone else wants to make similar changes in the future. In the file src/lib-index/mail-index.c: duplicate the function mail_index_set_error to mail_index_set_warning and call this function in /src/lib-index/mail_cache.c instead int mail_index_set_error(struct mail_index *index, const char *fmt, ...) { va_list va; i_free(index->error); if (fmt == NULL) index->error = NULL; else { va_start(va, fmt); index->error = i_strdup_vprintf(fmt, va); va_end(va); i_error("%s", index->error); } return -1; } changing the line : i_error("%s", index->error); to i_warning("%s", index_error); and for the file src/lib-storage/index/mbox/mbox-sync.c changing this code if (rec == NULL && uid < sync_ctx->idx_next_uid) { /* this UID was already in index and it was expunged */ mbox_sync_set_critical(sync_ctx, "mbox sync: Expunged message reappeared in mailbox %s " "(UID %u < %u, seq=%u, idx_msgs=%u)", sync_ctx->mbox->path, uid, sync_ctx->idx_next_uid, sync_ctx->seq, messages_count); ret = FALSE; rec = NULL; } else if (rec != NULL && rec->uid != uid) { /* new UID in the middle of the mailbox - shouldn't happen */ mbox_sync_set_critical(sync_ctx, "mbox sync: UID inserted in the middle of mailbox %s " "(%u > %u, seq=%u, idx_msgs=%u)",sync_ctx->mbox->path, rec->uid, uid, sync_ctx->seq, messages_count); ret = FALSE; rec = NULL; from mbox_sync_set_critical( etc... to mail_storage_clear_error(storage) i_warning("Error text"... mail_storage_set_internal_error(storage) to clear and set the storage pointer Hopefully that's all clear. If you have any questions, please let me know.

[Dovecot] outlook problem if TLS mailsettings are off
by Georg Käfer 27 Mar '09

27 Mar '09

Dear List, I dont know if its a config problem or its an outlook 2007 issue. Behaviour: If I set /etc/dovecot/dovecot.conf: Following is valid with IMAP mailboxes only: disable_plaintext_auth = yes # outlook 2007 with TLS in/out enabled) can show index of mails and klick on mail does preview / doubleklick opens mail PERFECT AS INTENDED disable_plaintext_auth = no # outlook 2007 with TLS/SSL OFF can show index of mails, but (double)-/klick on mail gives me "sandwatch"-mouspointer and I've to restart outlook again (and enable TLS again to get it work again) with POP3 mailbox both variants are working smoothly. Other ssl/tls settings: ssl_disable = no login_process_per_connection = yes using or not using following makes no difference... imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh I'm sad - but I cant force SSL/TLS for my users - so I cant "solve" this by using "disable_plaintext_auth = yes" Is there any way out of the dark? my data: gentoo linux dovecot 1.1.7 postfix 2.5.5 postfixadmin-2.2.1.1 mysql 5.0.70-r1 php 5.2.8-pl12 dovecot -n # 1.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-gentoo-r3 i686 Gentoo Base System release 1.12.11.1 ext3 protocols: pop3 pop3s imap imaps ssl_cert_file: /etc/ssl/dovecot/server.pem ssl_key_file: /etc/ssl/dovecot/server.key 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_max_userip_connections(default): 10 mail_max_userip_connections(imap): 10 mail_max_userip_connections(pop3): 30 first_valid_uid: 8 last_valid_uid: 8 first_valid_gid: 12 last_valid_gid: 12 mail_privileged_group: mail mail_uid: mail mail_gid: mail mail_location: maildir:/var/mail/%d/%n/Maildir/:INDEX=/var/mail/%d/%n/indexes mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/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/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail 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: plain login passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: prefetch userdb: driver: sql args: /etc/dovecot/dovecot-sql.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: mail group: mail regards, Georg

[Dovecot] very slow pop3 downloads

Hi all, I have a dovecot installation which very suddenly decided to slow to a crawl yesterday after being totally fine for months.

[Dovecot] Preventing IMAP folder deletion?
by dovecot＠corwyn.net 27 Mar '09

27 Mar '09

Hi! I'm running postfix with dovecot using mysql for user accounts, with Outlook being used as the IMAP mail client. I'm using a mail delimiter ("+") and mail automatically goes to a Spam folder as part of spam filtering with amavisd and spam assassin. It's configured so that folders won't automatically create; if the folder isn't there mail delivers to the inbox (so that spam doesn't create extra folders). the problem I ran into today is that a user deleted the Spam folder. While recreating it isn't that hard, is there a way I can prevent them from being able to delete specific folders in IMAP? In squirrelmail I can create "system" folders that the user can't change or delete, but that's client based. Since I don't see that ability in Outlook, can I somehow configure dovecot so the user can't delete specified folders? Thanks Rick Rick Steeves http://www.sinister.net "The journey is the destination"

[Dovecot] Version 2.0 with multiple IP/TLS certificate support.
by Gordon Dickens 26 Mar '09

26 Mar '09

Hello, I sent this email earlier but for some reason it did not go through so I will try again! I am using Dovecot on several servers that require multiple domain SSL certificates. I like Dovecot very much because of its speed and stability. Currently, Dovecot does not support multiple SSL certificates directly although I have gotten around this problem with multiple Dovecot instances running multiple configuration files. However, I would prefer to have one configuration file that supports multiple domain certificates. My understanding is that Dovecot Version 2.0 will have this "multiple SSL certificate" feature. So, my question is, when is version 2.0 projected to be released? Many thanks! Gordon Dickens

[Dovecot] v1.2.beta4 released
by Timo Sirainen 26 Mar '09

26 Mar '09

http://dovecot.org/releases/1.2/beta/dovecot-1.2.beta4.tar.gz http://dovecot.org/releases/1.2/beta/dovecot-1.2.beta4.tar.gz.sig This release fixes a memory corruption bug related to MODSEQ handling in earlier v1.2 releases. Memory corruption means that it's a security bug and possibly exploitable. MODSEQ code is new in v1.2, so v1.1 and older releases are not affected. Other than that, there is an ESORT bugfix and other fixes that were added to v1.1 branch too.

[Dovecot] Missing TMP folder - Dovecot 1.2 Beta3
by Matt Rude 26 Mar '09

26 Mar '09

Recently after upgrading to 1.2 Beta3 from 1.1.13, I started to defer mail. After looking into it deeper, it looks like Dovecot/sieve now asks for a tmp folder in the imap (maildir) folder. Once I added the tmp folder as the logs indicants, the mail was processed normally. I have split my Inbox and imap store to different folder. Looking at what it's trying to do, it looks to me that dovecot/sieve expect the imap directory to be the Inbox.

I use dovecot mailbox as destination of fetches from a few POP mailboxes. I would like to pass name of "source mailbox" to sieve script via deliver's command line option(s). As I understand I should use -a "mailbox@domain". How it would be accessible in sieve script? -- [pl>en: Andrew] Andrzej Adam Filip : anfi(a)onet.eu It is always the best policy to tell the truth, unless, of course, you are an exceptionally good liar. -- Jerome K.

[Dovecot] Dbox Upgrade Problem With MAILBOXDIR
by Alan Swanson 25 Mar '09

25 Mar '09

Hi. Trying to upgrade from Dovecot 1.1.11 to 1.1.13 but having a problem with imap process segfaulting. Backtrace is below. I presume it's related to these MAILBOXDIR changes but the only documentation is the single line in the news for changing to ":MAILBOXDIR=mailboxes" when using dbox. Current configuration is "mail_location = dbox:~/Mail" so what exactly should be changed here?

[Dovecot] selection correct auth with multiple auth methods
by jm 24 Mar '09

24 Mar '09

How do you control which socket or authentication process dovecot's pop3 daemon chooses to use? I've got a user database with two flags one to allow pop3 access and the other to allow the use of auth smtp. There are two authentication instances configed, thus, auth default { .... passdb sql { args = /etc/dovecot-sql-postfix.conf } .... socket listen { master { path = /var/run/dovecot/auth-master mode = 0660 user = group = } } auth postfix { ..... passdb sql { args = /etc/dovecot-sql-postfix.conf } .... socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } From the logs and testing pop3 is using the postfix authentication instance and not the default as expected. Does anyone out there know how control dovecot's pops daemon authentication choice? This infomation seems to be lacking in the documentation I can find. Jeff.

[Dovecot] Making changes to dovecot log levels
by Thomas M Goerger 24 Mar '09

24 Mar '09

Hi Timo, Awhile back I'd written about making changes to some of the log levels that dovecot writes to to stop the process from writing these to monitor. I wanted to run a few changes by you for this, just to make sure these won't cause problems somewhere else. And to send this to the list, in case anyone else wants to make similar changes in the future. In the file src/lib-index/mail-index.c: duplicate the function mail_index_set_error to mail_index_set_warning and call this function in /src/lib-index/mail_cache.c instead int mail_index_set_error(struct mail_index *index, const char *fmt, ...) { va_list va; i_free(index->error); if (fmt == NULL) index->error = NULL; else { va_start(va, fmt); index->error = i_strdup_vprintf(fmt, va); va_end(va); i_error("%s", index->error); } return -1; } changing the line : i_error("%s", index->error); to i_warning("%s", index_error); and for the file src/lib-storage/index/mbox/mbox-sync.c changing this code if (rec == NULL && uid < sync_ctx->idx_next_uid) { /* this UID was already in index and it was expunged */ mbox_sync_set_critical(sync_ctx, "mbox sync: Expunged message reappeared in mailbox %s " "(UID %u < %u, seq=%u, idx_msgs=%u)", sync_ctx->mbox->path, uid, sync_ctx->idx_next_uid, sync_ctx->seq, messages_count); ret = FALSE; rec = NULL; } else if (rec != NULL && rec->uid != uid) { /* new UID in the middle of the mailbox - shouldn't happen */ mbox_sync_set_critical(sync_ctx, "mbox sync: UID inserted in the middle of mailbox %s " "(%u > %u, seq=%u, idx_msgs=%u)",sync_ctx->mbox->path, rec->uid, uid, sync_ctx->seq, messages_count); ret = FALSE; rec = NULL; from mbox_sync_set_critical( etc... to mail_storage_clear_error(storage) i_warning("Error text"... mail_storage_set_internal_error(storage) to clear and set the storage pointer Hopefully that's all clear. If you have any questions, please let me know.

[Dovecot] Problem with dovecot + imap idle + qmail-local delivery
by Jochen Schug 24 Mar '09

24 Mar '09

Hi, I've recently switched from courier-imap to dovecot. Everything seemed to work fine, but after I while I noticed that dovecot is occasionaly causing problems with delivery of new incoming mails. System: Gentoo Linux, kernel 2.6.19, qmail 1.03, vpopmail 5.4.26 , dovecot 1.1.11, maildir, mail store on ext3. Symptoms: qmail is having trouble with the mail delivery. First I thought it had something to do with vpopmail or dovecot's quota support, but I tracked it down to qmail-local. I tried two different versions, one with Bill Shupp's maildir++ patch and one without. With the patch, I'm getting "User_over_quota._(#5.1.1)" errors. Mail is delivered once and sender is sent a notification about the exceeded quota. Without the patch, I get "Temporary_error_on_maildir_delivery._(#4.3.0)". Mail is delivered, but delivery is tried again and again. This only happens if a MUA is logged in to the mailbox and IMAP IDLE is being used. If the MUA is disconnected: fine. If dovecot is stopped: fine. I tried a couple of different things, all without success: - upgraded dovecot from 1.1.7 to 1.1.11 - compiled a new kernel with inotify support and recompiled dovecot - migrated mail store from reiserfs to ext3 - disabling quota support in dovecot - tried dovecot's various file locking mechanisms Right now I'm working around this by removing IDLE from the capabilities. This solves the problem, but leaves me with a less functional IMAP server. Any help is greatly appreciated.

[Dovecot] Staged migration from mbox to maildir
by Stewart Dean 24 Mar '09

24 Mar '09

So much changes in this migration that the ideal way to do it would be to begin with a few users or a department, then migrate the users affinity group by affinity group: first an institute or so, then the faculty, then the staff, then the students, moving to bigger and bigger groupings as the bugs work out of the migration and the move becomes more assured. We use sendmail and procmail. There's no problem there, as the ~./procmailrc can be changed to over-ride the mbox default until all groups are done and it become the default. The problem comes with IMAP. While dovecot can tell if a folder is mbox or maildir, it has to be pointed to the right place (by namespace definitions in the client, IIRC), and the default of putting the inbox under ~/mail is one I'd like to embrace for various reason...but given that that means moved inbox folders and *that* means either making a global change (there goes staged migration) OR changing the namespace definitions on each PC. I can get to the early few and change the namespaces definition, but there doesn't appear to any equivalent (enlighten me, if I'm missing something) to ~/.procmailrc for imap, so that I don't have to get on the client machine. Is this correct or am I (hopefully) wrong and there *is* a way to change things on the server that allows for staged migration? Oh, I would so like to be wrong!

[Dovecot] Released Sieve v0.1.4
by Stephan Bosch 23 Mar '09

23 Mar '09

Hello Dovecot users, Not much Sieve development was done in the last five weeks, but some important platform-dependent bugs were found and repaired. The main new feature is the addition of a custom Sieve language extension for debugging in the Sieve command line tools. Changelog Sieve v0.1.4: * Started work on the sieve-filter tool. With this command line tool it will be possible to (re-)apply Sieve filters on a mail folder. It is currently undocumented and far from functional. + Added a custom debug extension that provides the possibility to print debug messages from scripts executed by the Sieve tools. - Fixed issue with opening relative paths as a mail file. Bug reported by Ian P. Christian. - Fixed MAC OSX compile problem. Turns out the extern modifier was missing at multiple places. Bug reported by Edgar Fuss. - Fixed Solaris compile problem: removed unecessary and unportable linker flags that caused compile to fail. Bug reported by Andres Yacopino. The release is available as follows: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.4.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.4.tar.gz.sig Have fun testing the new release and don't hesitate to notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] v1.1.13 and v1.2.beta3 released
by Timo Sirainen 21 Mar '09

21 Mar '09

http://dovecot.org/releases/1.1/dovecot-1.1.13.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.13.tar.gz.sig http://dovecot.org/releases/1.2/beta/dovecot-1.2.beta3.tar.gz http://dovecot.org/releases/1.2/beta/dovecot-1.2.beta3.tar.gz.sig Looks like Friday the 13th isn't the best day to make releases. :) These releases fix two bad bugs in v1.1.12. - v1.1.12's MAILBOXDIR changes broke accessing mails in some setups - v1.1.12's login_executable -D checking changes caused dovecot to crash at startup if protocols setting contained only pop3. - mbox: pop3_lock_session=yes was broken with mail_privileged_group.

[Dovecot] Single Instance Storage still on the roadmap?
by Charles Marcus 20 Mar '09

20 Mar '09

Hey Timo, I was curious where Single Instance Storage fits in on the roadmap, now that you are maybe settled in in your new digs... Is it still coming soon? Has it been pushed back by your new employers priorities? Its real high on mine, so if has been back-burnered, I'll need to start looking for alternatives... Thanks, -- Best regards, Charles

[Dovecot] update of current quota usage
by floss＠pBartels.info 20 Mar '09

20 Mar '09

Hello, I use Dovecot 1.1.11 and store the current quota usage in a Database. As far I can see it, the quota usage is updated each time dovecot performs an action on a mail. For example if a new mail is stored in the inbox, the current quota usage is increased. If a mail is deleted the quota usage is decreased. If there are still existing E-Mails in the inbox, before quota is turned on or if I perfom changes on the "mail storage" myself (for example purging trash or spam, or something) the current quota usage is NOT updated automatically by dovecot. For example I copy some mailboxes to my server, then the current quota for this mailboxes is still zero. Is it correct that dovecot can't do this for me? If yes, it seems I have to write my own (simple) update script and run it sometimes croned (because I don't really trust the actual quota implementation) and/or I have to update the current quota usage each time I perform actions myself. This "workaround" is easy by using a DB storage, but what about other implementations? Wouldn't it be nice if dovecot could do this or provide a tool for it? Thank you! Philipp

[Dovecot] ESORT broken in Dovecot 1.2
by Michael M. Slusarz 20 Mar '09

20 Mar '09

Looks like ESORT is broken (just compiled 1.2 from hg 10 minutes ago). Here is the command I'm using and the corresponding error message: C: 5 UID SORT RETURN (ALL COUNT) (ARRIVAL) US-ASCII UNSEEN S: 5 BAD Error in IMAP command UID: Invalid sort argument. The corresponding UID SORT command (without the RETURN syntax) works fine: 5 UID SORT (ARRIVAL) US-ASCII UNSEEN * SORT 5 OK Sort completed (0.000 secs). michael

[Dovecot] fchown() error with Public Folders
by Stephen Carville 18 Mar '09

I was able to get public folders to work with a dedicated account for the hierarchy and ACL's for individual users. I have location defined so that each user has a local index and control files location = maildir:/usr/mail/public/cs/mail:CONTROL=~/Maildir/CS:INDEX=~/Maildir/CS Now i am seeing the folliwing error in the logs. dovecot: IMAP(stephen): fchown() failed with file /home/stephen/Maildir/CS/.Incoming/dovecot.index.log: Operation not permitted As I understand it, dovecot runs as root but the the IMAP process that servicers the request runs as the user so naturally the fchown() fails.

[Dovecot] IMAP ACLs not working
by Seba 18 Mar '09

18 Mar '09

Hi, I've some problems to get folder ACLs working with Dovecot. I've defined some folders (like drafts, spam etc.) for every user and created a dovecot-acl file in every folder so that users can not delete or rename these folders but this does not work as expected. Config ===== Debian Lenny 5.0 Dovecot 1.0.15 dovecot.conf ========= protocols = imap protocol imap { listen = xxx.xxx.xxx.xxx } disable_plaintext_auth = yes log_timestamp = "%Y-%m-%d %H:%M:%S " ssl_disable = yes mail_location = maildir:/home/vmail/%Ld/%Ln namespace private { separator = . prefix = inbox = yes } mail_privileged_group = vmail protocol imap { mail_plugins = acl } protocol lda { postmaster_address = postmaster(a)example.com hostname = hostname(a)example.com mail_plugins = cmusieve } auth_username_translation = %Lu auth default { mechanisms = cram-md5 passdb pam { } passdb sql { args = /etc/dovecot/dovecot-sql.conf } userdb passwd { } userdb static { args = uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes } user = root socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 user = vmail } client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } Folder structure =========== (For dovecot-acl) /home/vmail/example.com/user/.Spam/dovecot-acl dovecot-acl contains =============== owner lrwstiek For me the config looks OK and I can't find an error... When I change the dovecot-acl to "owner l" for example it seems that this change has no effect. Are there an error in my setup? Seba

[Dovecot] mbox on NFS + automount, folder creation -> mkdir_parents() failed
by Sebastian Kayser 18 Mar '09

18 Mar '09

Hi, i am about to migrate some internal imapd mboxes to dovecot. Regular access is fine, just when i want to create a folder i get the following error message in the logs: Mar 18 17:36:57 pulsar dovecot: [ID 107833 mail.error] IMAP(skayser): mkdir_parents(/home/skayser) failed: Operation not applicable /home/skayser is mounted via autofs. When i set mail_location to a subdirectory within /home/skayser, folder creation works. From looking at the truss output dovecot tries to mkdir() the parent and doesn't seem to like the ENOSYS that is returned when the directoy is an autofs mountpoint.

[Dovecot] NFS-error with dovecot 1.1.12

Uhg, I win the CluelessnUnobservant Award for this. Thanks everyone for the followups. I caught that myself yesterday and fixed the problem on Postfix's side. To sum up in case anyone else runs in to this, the mistake I made was in assuming that Postfix just made the handoff to Dovecot and that Dovecot would handle the rest, so I commented out the parts of the old config where Postfix handled this when I was using Postfix virtual transport. Once I restored those and gave Postfix the query it needed, it worked fine. Thanks for bearing with me, everyone. Kat

Re: [Dovecot] Dovecot LDA and "undeliverable" emails

Timo wrote: > So Postfix delivers bounces to everyone by calling Dovecot LDA > separately for each bounce? Looks like a Postfix configuration problem > to me. I should have been more specific... because we'd also changed domain names at the time we moved over to using Dovecot as the LDA, I temporarily disabled automatically bouncing mail addressed to invalid users because I figured that we'd have at least one who decided that they didn't want the standard formation of email addresses... What I'd wanted to happen was for Postfix to accept the message(s) and then for them to be delivered to the postmaster address so that I could address the issue. I'm still unsure as to why, when Dovecot couldn't find the user in the tables, it copied the message to every user of the system - that seems like odd behavior, which indicates that even though the system is "working", I need to fine-tune something.

[Dovecot] Dovecot as a POP3-/POP3SSL-proxy in front of exchange 2003
by south africa 17 Mar '09

17 Mar '09

Dear all, im looking for a solution to protect an Exchange 2003 email server from direct "pop3-internet-connects". Is it possible that Dovecot act as a POP3-/POP3SSL-Proxy, "LDAP-authenticate" all user logins to a Windows 2003 domain controller and forward then all POP3-connects to a single Exchange 2003 server? Could someone give me some advices or a link for howtos for this solution? The howto on www.dovcot.org (http://wiki.dovecot.org/HowTo/ImapProxy) does not fit in my situation because it prefere a mysql server and not a LDAP-server/domain-controller.

[Dovecot] Errors on mbox to Maildir conversion
by Phill Edwards 17 Mar '09

17 Mar '09

I have Julian Fitzell's migrateuser.sh script which uses mb2md-3.20.pl to convert a mailbox in mbox format to Maildir. I have set up a test user called "mailtest" which has mail as follows: /var/mail/mailtest /home/mailtest/mail/ Drafts MoreStuff Sent Items Stuff After the conversion I want all this user's mail to be in /home/mailtest/Maildir/ I'm not quite sure how to run the migrateuser.sh script, but I think it's like this (run as user mailtest): $ /usr/local/bin/mb2md/migrateuser.sh mailtest /home/mailtest /home/mailtest/Maildir When I run this I get the following output: mailtest -- Migrating INBOX...

[Dovecot] folders are not under INBOX
by Ondrej Svoboda 16 Mar '09

16 Mar '09

hi guys, I hope it's common trouble, but I'm not able to find a solution: - i'am using courier imap and trying to migrate to the dovecot - on courier I have all folders as subfolder of Inbox - i.e. Inbox.Sent but on dovecot the folder Sent is not subfolder of Inbox, but its on the same level. Please is there some possibility to have the subfolders the same behaviour as in courier? we have lot's of customers so after the upgrade the folders can't change. thank you ondrej

[Dovecot] Dovecot and high availability
by d dimov 16 Mar '09

16 Mar '09

Hello dear all. Please accept apologies if the topic was discussed already, tried searching the archives but found few details. What I am looking for would be the best way to making Dovecot highly available in an environment where: two Alteons are load-balancing two Dovecot servers, each Alteon seing both of them; the clients are using exclusively POP3; low volume; in case of a Dovecot server failure service should fail over to the other node with preferably no manual intervention. Failover could mean Alteons just ignoring the failed host and routing all requests to the healthy one. Would it be shared NFS volume mounted on both of the servers from some NAS, maildirs put on that volume and both Dovecots seing the mailboxes simultaneously? Any risks? Is there a good document describing such a setup? Thank you in advance and please indicate if I missed relevant details. Best regards, Dimov

The only symptom is the log messages. The client sees nothing unusual, at least in this case where the session is a retrieval of one large message. I haven't tried long sessions retrieving multiple messages. If I remove pop3_lock_session = yes, the issue does not occur. I don't think I need it. I put it in a long time ago to attempt to solve a problem that was actually caused by something else. Since removing it does seem to avoid this issue, I will leave it out, but I'm reporting this anyway as it seems there may be some underlying problem. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

[Dovecot] pop-proxy to redundant servers ?
by Jan-Frode Myklebust 15 Mar '09

15 Mar '09

I'm considering putting two servers with failover IP-addresses in front of our pop/imap cluster, with dovecot in proxy-mode running on both servers. But, can dovecot handle more than one backend server for each user ? I.e. I would want to point the dovecot proxy to send userX to backend-server1, or backend-server2 if backend-server1 is down. Is something like that possible ? -jf

Changes in v1.2.beta2 since beta1: * Authentication userdb: Renamed system_user to system_groups_user. Probably pretty much no one used this feature. * deliver no longer creates temp files to /tmp. They're instead created to the users' mailbox directories. - IMAP: Fixed SORT command crashing - POP3 was broken in beta1 - Fixes to virtual mailboxes - Fixes to IMAP ACL support Changes in both v1.1.12 and v1.2.beta2: * Added :MAILBOXDIR= to mail_location to specify the root dir for mailboxes. dbox users should migrate to ":MAILBOXDIR=mailboxes", because that's going to be the default in v1.2+. + Linux: Adding -D parameter to login_executable makes login processes dump core to login_dir if they crash. - IMAP: SELECT didn't always return first unseen message in reply - POP3: pop3_lock_session=yes didn't use mail_privileged_group while dotlocking. - mbox: Don't crash if >=8192 bytes long line begins with "From ". - Maildir: More fixes to handling over 26 keywords. - Several logging fixes and improvements - Fixed authentication caching with non-plaintext mechanisms when using a blocking passdb (e.g. MySQL) - Fixed DIGEST-MD5 authentication with user@domain style usernames.

[Dovecot] setting up both system password users AND virtual users
by Jim Pazarena 14 Mar '09

14 Mar '09

I'm afraid that I am a rookie at dovecot, and cannot seem to figure the configuration for a dual system & virtual setup. For now I am using POP3 ---only--- I've got the "system" working, but cannot figure out how to add the virtual system. The docs aren't quite clear enough for me to understand. The wiki example for dynamic passwd-file locations shows: mail_location = maildir:/home/%d/%n/Maildir userdb passwd-file etc etc I am using mbox, not maildir, AND I've already used mail_location for my system accounts with the following line: mail_location = mbox:~/mail/:INBOX=/mail/%u In the case of my virtual users, the mail is stored in INBOX=/mail/VIRTUAL/%d/%u and the password file is stored in /exim/etc/VIRTUAL/%d/passwd would someone kindly help me with this? thanks!

[Dovecot] pam_authenticate() failed: authentication error
by Zbigniew Szalbot 14 Mar '09

14 Mar '09

Hello, I would like to ask for your help. I have noticed some error messages issued by dovecot. Mar 13 20:00:57 relay dovecot: auth-worker(default): pam(example(a)example.com): pam_authenticate() failed: authentication error (/etc/pam.d/dovecot missing?) Not surprisingly $ l /etc/pam.d/dovecot ls: /etc/pam.d/dovecot: No such file or directory The funny thing is that authentication does work but I guess I have something misconfigured. I'd appreciate if you could help me. I am on a FreeBSD system (7.0) if that matters. Thank you! -- Zbigniew Szalbot

Hi, all. I use dovecot-1.1.11 with OpenLDAP backend. but i found the mail_location is not correct. How can i override mail_location setting in dovecot.conf? LDAP user data and dovecot config are attached below. in dovecot config, mail_location is: ---- mail_location = maildir:/%Lh/%Ld/%Ln/:INDEX=/%Lh/%Ld/%Ln/ ---- but the correct maildir should be 'homeDirectory' + 'mailMessageStore': ---- maildir:/home/vmail/a.cn/w/ww/www/ ---- LDAP user: ---- dn: mail=www(a)a.cn,ou=Users,domainName=a.cn,o=domains,dc=iredmail,dc=org objectClass: inetOrgPerson objectClass: mailUser objectClass: top cn: www sn: www uid: www mail: www(a)a.cn accountStatus: active homeDirectory: /home/vmail mailQuota: 104857600 userPassword: {SSHA}crkYO5tg8KRkOY7W3bRgjtLQ+79U4NgG enabledService: mail enabledService: smtp enabledService: pop3 enabledService: imap enabledService: deliver mailMessageStore: a.cn/w/ww/www/ ---- Dovecot ldap config file: ---- user_attrs = homeDirectory=home,=sieve_dir=/home/vmail/sieve/%Ld/%Ln/,mailMessageStore=maildir:mail,mailQuota=quota_rule=*:bytes=%$ ---- Dovecot main config file: ---- # dovecot -n # 1.1.11: /etc/dovecot.conf # OS: Linux 2.6.18-128.el5 x86_64 Red Hat Enterprise Linux Server release 5.3 (Tikanga) log_path: /var/log/dovecot.log protocols: pop3 pop3s imap imaps listen: * ssl_cert_file: /etc/pki/iRedMail/SSL_Cert.pem ssl_key_file: /etc/pki/iRedMail/SSL_Key.pem 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_uid: 500 mail_gid: 500 mail_location: maildir:/%Lh/%Ld/%Ln/:INDEX=/%Lh/%Ld/%Ln/ 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_plugins(default): quota imap_quota zlib mail_plugins(imap): quota imap_quota zlib mail_plugins(pop3): quota zlib mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login default_realm: a.cn user: vmail passdb: driver: ldap args: /etc/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot-ldap.conf socket: type: listen client: path: /var/spool/postfix/dovecot-auth mode: 438 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 438 user: vmail group: vmail plugin: quota: maildir quota_rule: *:storage=10M expire: Trash 7 Trash/* 7 Junk 30 expire_dict: proxy::expire auth_socket_path: /var/run/dovecot/auth-master sieve: /home/vmail/sieve/%Ld/%Ln/.dovecot.sieve dict: expire: db:/var/lib/dovecot/expire/expire.db ---- -- Best regards.

If so, I think the behavior is correct. Maybe change the query to: where username = '%n' and (domain = '%d' or ('%d' = '' and domain is null)) And change all the domain='' to domain=NULL.

[Dovecot] New to list, got a quota question
by Vlad Sedov 13 Mar '09

13 Mar '09

Hello folks - I'm running dovecot on top of qmail/vpopmail/mysql, serving up about 2500 mailboxes. Everything is running very smooth and fast.... I recently upgraded dovecot to 1.1, so I'm trying to implement some extra features like IMAP quotas. I'm using the sql passdb, with the following config: driver = mysql connect = host=/var/lib/mysql/mysql.sock user=username password=password dbname=vpopmail default_pass_scheme = PLAIN password_query = SELECT CONCAT(pw_name, '@', pw_domain) AS user, pw_clear_passwd AS password FROM vpopmail WHERE pw_name = '%n' AND pw_domain = '%d' user_query = SELECT pw_dir as home, 508 AS uid, 503 AS gid FROM vpopmail WHERE pw_name = '%n' AND pw_domain = '%d' My vpopmail installation keeps the quota information in the mysql database (pw_shell field) instead of maildirsize. The quota is in maildir format, e.g. 400M or 50331648S. Unlimited quota is specified as NOQUOTA. The question is... Is it possible to make dovecot understand this format and get it directly from SQL (via user_query, for example) or would it be easier to reconfigure the vpopmail installation somehow to use maildirsize? Thanks! Vlad

[Dovecot] how to handle CA CRL updates with client certificate verification context ?
by Raphael PRECIGOUT 13 Mar '09

13 Mar '09

Hello, As far as I can read in the Dovecot SSL configuration wiki page, each CA cert must be followed by the related CA CRL in the client certificate verification context ("ssl_ca_file" setting). In my company we do have our own PKI and as soon as Client certificate is compromised we do revoke it and update the related CA's CRL. Does that mean that I have to issue a new "ssl_ca_file" file as soon as our issuing CA CRL is updated ? If yes, does someone has an idea on how to do so ? Is it then necessary to restart dovecot process (to take the "ssl_ca_file" file changes into account) ? Does Dovecot have a way to check the issuing CA CRL automatically ? (the CRL is published in DER format and is accessible though http, the URI is mentionned in the CRL Distribution points of the CA certificate) Thanks in advance for your help. Regards, Raphael

[Dovecot] Problem with sasl auth with postfix...
by Douglas M. Stanley 13 Mar '09

13 Mar '09

Hello list, I'm running into some problems, and I couldn't find any info about this anywhere on the net. I recently set up a new debian lenny machine, and used my notes from the last debian etch machine I set up, which basically is for postfix + dovecot for sasl auth. On my old etch box, in the dovecot.conf, in the auth default section, I have a socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } However, if I use the same config on my lenny setup, dovecot fails to start, and I see this in my logs: Mar 13 19:16:30 mailserver dovecot: Dovecot v1.0.15 starting up Mar 13 19:16:30 mailserver dovecot: auth(default): User doesn't exist: postfix Mar 13 19:16:30 mailserver dovecot: Auth process died too early - shutting down Mar 13 19:16:30 mailserver dovecot: child 4623 (auth) returned error 89 Now if I comment out the user and group lines, it works fine, but the socket is owned by root, and so I have to change the mode line so that it's world readable in order for postfix to use it. The version of dovecot in etch is: 1.0.rc15-2etch4 and the version in lenny is: 1.0.15-2.3 Any ideas why this might be happening? Did the syntax to do this change between those versions? Any input? I guess I don't mind leaving it world readable, but I wasted an entire morning trying everything to get it to work, so I guess I'm hoping some one atleast has an answer as to why it doesn't work. Thanks, Doug

[Dovecot] Using LDAP for Dovecot extra/regular fields
by Jack Stewart 13 Mar '09

13 Mar '09

Hi, We're moving to a dovecot proxy / server configuration in order to make sure that a users go to a specific server. If someone has used these LDAP for this, there are a few things that I wish to verify. Dovecot does not verify that type of the LDAP attribute, only that the returned value works. If a boolean is used for a yes/no field, then FALSE sets the field to no and TRUE sets the field to yes. If a multivalue attribute is used for a single value field, the last returned value for the LDAP lookup is used in that field (i.e. host will use the last value). If a string attribute is returned for a yes/no field and has any value, then the associated field is set to true. There is no automatic failover with the host field so if the remote host is down, the IMAP connection no longer works. I'm fairly sure of all of these except for the boolean. Now this is just due diligence. I don't know that turning on/off or switching LDAP attributes is the right way to go to handle failover but it might work for phased rollout. My feeling is the best configuration will be using a secondary IP address that has to be manually turned on for a host after a reboot or shutdown. This creates a poor mans "fencing". The secondary can either be brought up on another host or handled via a load balance with DSR/backup server. As a practical matter, it is probably worth setting sensible attributes for each field (i.e. numeric for host, boolean for proxy/proxy_maybe etc). Any interest in registering an LDAP object class for dovecot? ---Jack

[Dovecot] Maildir dirty syncs
by Timo Sirainen 13 Mar '09

13 Mar '09

http://dovecot.org/patches/1.1/maildir-dirty-syncs.diff This patch adds a new maildir_very_dirty_syncs setting. If set to "yes", Dovecot assumes it's the only one changing the cur/ directory (so other MDAs can add mails to new/ without problems). This makes it possible to avoid rescanning the cur/ directory all the time looking for filenames. It also looks like (in stress testing) it still scans the cur/ directory unneededly in some situations, but it shouldn't be common. Maybe I'll look into it some day to see why. I'd be interested in hearing how large performance benefits it gives, if any. If they're big I could consider adding it to v1.1.12. If they're pretty much irrelevant I probably won't even bother adding the code to v1.2. I guess you mainly see the performance benefits with large/huge mailboxes.

[Dovecot] General approach question - am I doing this the right way?
by Alan Bates 13 Mar '09

13 Mar '09

Quick outline of my current working setup: I'm running dovecot 1.0.5 as an IMAP mail server on my ubuntu home server, which i connect to with my phone and several other machines to check my mail etc. i use getmail to collect mail from my various pop accounts. getmail filters the mail using spamassassin via a Filter_external, before moving it to my Maildir on the home server. Then when I connect to the home server from my various machines, IMAP manages the status of all the mail, so unread messages are common etc. All works very nicely. However I'd like to fix a minor annoyance... ...Spamassassin marks mail as SPAM but the mail client has to do the job of moving it to the Junk folder. I'd like the mail to be filtered on the home server on receipt. Am I just making things really complicated for myself? Is there a simpler setup for what I'm trying to do? Thanks in advance for any thoughts or suggestions

[Dovecot] Extremely custom mailbox locations
by Steve Kemp 13 Mar '09

13 Mar '09

I'm in the position where I'd like to offer IMAP access to a collection of email accounts which are stored in a very odd manner. Files are stored as: /blah/$dd-$mm-$yy/$domain/1234/1234 For example: /reject/12-3-2009/cvsrepository.org/35199/35199639 There is a single file for each mail, which I guess technically probably counts as an mbox folder, but only just. I can handle the custom login requirements I have, but I see no obvious way to create a mailstore from this information unless I build up a parallel symlink farm, such as: /imap/cvsrepository.org/{new cur tmp} I suspect if I fill cur/ with symlinks to each of the individual messages things will mostly work out OK, but I wonder if that is the best solution, or if there is a slim chance that I could serve this hierarchy without the intermediate step?

[Dovecot] which architecture to use?
by GVG GVG 13 Mar '09

13 Mar '09

Dear List, Based on the following installed environment: - OpenBSD (latest version!) - PostgreSQL - dovecot with SSL would like to have a mail server which accepts system as well as virtual users and being able to connect to their mailboxes either via an MUA (Thunderbird etc.) or a web interface (squirrel mail?). When using the web interface, non registered users should be able to creat e-mail accounts which will be dovecot virtual users! Which components should I use? Thanks

http://dovecot.org/tmp/dovecot-1.1.12.rc.tar.gz I would have already released 1.1.12, but it needed the MAILBOXDIR change described below, and I'm slightly worried that it might have broken some special setup. So please test first and I'll release in v1.1.12 then in a few days. * Added :MAILBOXDIR= to mail_location to specify the root dir for mailboxes. dbox users should migrate to ":MAILBOXDIR=mailboxes", because that's going to be the default in v1.2+. - IMAP: SELECT didn't always return first unseen message in reply - POP3: pop3_lock_session=yes didn't use mail_privileged_group while dotlocking. - mbox: Don't crash if >=8192 bytes long line begins with "From ". - Maildir: More fixes to handling over 26 keywords. - Several logging fixes and improvements - Fixed authentication caching with non-plaintext mechanisms when using a blocking passdb (e.g. MySQL) - Fixed DIGEST-MD5 authentication with user@domain style usernames.

[Dovecot] Imap logout message on Dovecot restart
by RutgerM 12 Mar '09

12 Mar '09

I'm trying to receive a "Disconnected" message in my logfile for the connected imap-clients when I restart dovecot. When you disconnect a client, you receive the following message in your log: Mar 12 21:45:55 mail dovecot: IMAP(mailbox(a)domain.com): Disconnected: Logged out bytes=7496/22441 When a IMAP client is connected and Dovecot is restarted, this message is not shown. This should be solvable by a script like this: #!/bin/sh unset LOG_TO_MASTER export USE_SYSLOG=1 exec /usr/lib/dovecot/imap But this logs the user that runs the script into the imap server and when I terminate this terminal I get a "Disconnected" message for the local linux user, which I don't need of course. Is there a way to get to what I want ? I want to log my IMAP statics for every day and I need to "disconnect" my imap clients for it in some way to receive the Disconnected message and count from there. Thanks.

[Dovecot] High load/corrupted indexes after moving mailboxes?
by Patrick A. Treptau 12 Mar '09

12 Mar '09

Hello, we're experiencing an odd issue after combining two vDisks used for mail storage into one big new LVM. We've done this in the past successfully and didn't experience a lot of problems. We stopped all services (dovecot/postfix) to ensure that mailbox contents (Maildir) will not be changed, rsynch'ed the mail to the new disks and restarted everything. When we restarted dovecot, we noticed a huge spike in load (average load in top and high cpu iowait) and isolated dovecot as the issue. At some point, the average load crept up to over 100 and crashed the server twice. However, over time the average load and cpu wait times went down slightly. I have noticed a spike in load after moving user's mail storage, but not like this. It almost looks like everyone is either re-indexing or re-caching their mail? Any help would be appreciated. We're on dovecot 0.99. -Pat

[Dovecot] migration from dovecot to dovecot on different servers without downtime (dovecot replication?)
by Pau Oliva 12 Mar '09

12 Mar '09

Hello, I have an imap server with huge Maildirs and several users running dovecot 1.0.13, I need to migrate all the imap accounts to a new box which runs dovecot 1.1.4. The requisite is that need to do it with no downtime or minimal downtime possible, and totally transparent for end users. I have tried IMAP<-->IMAP syncing using a master user in both servers and imapsync, however due to the huge Maildirs (some users have more than 10 years of mail) this tends to be quite slow and painful. Can I tar all the user's Maildir and move them from one box to the other, and then run imapsync again? which I assume that would be faster... or is there any better solution I am not aware of? (ie: I've seen some emails about dovecot replication on the list archives, but few details of how that should be configured). I'd appreciate any feedback or thoughts on this matter. Thank you. Cheers, Pau Oliva

[Dovecot] GUI/WUI for creating (common) sieve scripts?
by Roderick A. Anderson 11 Mar '09

11 Mar '09

Anyone aware of a Web User Interface or GUI to allow users to create simple/common-type sieve scripts? I found the sieve testing and have used it as I play; plus mangesieve (and Net:ManageSieve.pm) but want to allow users to build so some clicking and maybe a little typing and then end up with some filters. So before I go invent this wheel I'd like to know what others are doing? TIA, Rod --

[Dovecot] Error crosscompiling
by Diego Roversi 10 Mar '09

10 Mar '09

Hi, I was trying to crosscompile dovecot, but I got some error: --with-notify=inotify don't work, as it try to run a test program to verify if inotify is supported in the building platform. Solved with --with-notify=dnotify. Ihmo, is more a hack than a solution. | checking whether posix_fallocate() works... configure: error: cannot run test program while cross compiling I can't find an a suitable option for this error. Again the problem is that configure can't run an executable for a different platform. It's possible to set a safe default?

[Dovecot] Random timeouts on mailboxes
by Bastien Semene 10 Mar '09

10 Mar '09

Hello, My dovecot server is currently having random issues when users want to acces their mailbox. When the issue is occuring there's a timeout. It's random because it happens more or less often and is not dependent on a user or the way their check the mailbox. The time during the problem occurs is random, sometimes it's less than a minute, sometimes it's some hours. When a user can't connect to its mailbox, he generally can receive its emails through his BlackBerry (it's just to illustrate the fact that it doesn't seem to be linked to an account). When this issue occurs they can't receive the headers from any folder (INBOX, custom, sent, ...) and can't read mails that headers are known by the mail client. When there's timeout, users can send emails (same jail and with an error when the client want to write a copy in the sentbox) and use the calendar server for example (on the same machine). Dovecot is running on a FreeBSD 7.0 32bits, 4GB RAM, Intel Xeon QuadCore @ 1.86 Ghz, and 3*500Gb SATA-2 RAID-5 disks. The box is hosting jails, and the mail jails ( imap + smtp, clamav + spamassassin ). The mail jails are new (since August 2008) but worked great since the beginning of this year. The server is hosting 122 accounts currently. My first thought was that there's an I/O issue, the disks are maybe too busy or there's paging that result in a timeout. I check it through vmstat an top commands but nothing appears, there's always some memory free (between 90-300 MB) and a very little paging, generally around 1MB. The fault are under a hundred and when, few times, it has more than a hundred (generally under 200) the next snapshot is under 100. I set the screen/line to refresh every 5 seconds. I shutdowned all jails not directly related to the mail service but the problem still occured. I also separated clamav and spamassassin from imap and smtp to a different box. After that I checked the dovecot config to lighten it, and ( only ) disabled fsync. I upgraded the RAM, added memory is used, but nothing changed. The human resources are constantly changing here, we were more before the problem started than now (around 10-15%), to illustrate the fact that I don't think it is linked to the number of users. I tried to recreate some accounts having the issue, but the problem appeared again. I upgraded Dovecot Friday to 1.1.11 from 1.1.7 (The installation was before 1.1.7, I did an upgrade some times ago). I used a command script to log Thunderbird's IMAP activity, everything is fine but there's no timestamp in the logs. So I'm only sure now this is not an erroneous packet/info sent problem. I watched the TB doc ( http://www.mozilla.org/projects/nspr/reference/html/prlog.html#25306 ) but there's no directive to put a timestamp for each line of log. The network is fine. I tried different configuration to be sure a device isn't doing something weird. Now, I don't know what to check to identify the issue. If anyone has any idea I didn't wrote here, or if I did erroneous interpretation(s) from the datas, I'll be glad to know. Regards, -- Bastien Semene Administrateur Réseau & Système

Would you give me some advice if I make this specialty as a plugin? Thank you! WD David from China.

Re: [Dovecot] Random timeouts on mailboxes
by listacc＠gmx.de 09 Mar '09

09 Mar '09

Hi Bastien, just a little thought because I had an issue like this (but with cyrus): Where is your thunderbird installation stored? In my case, it was not locally but on some windows mapped drive, and so also the imap cache of thunderbird was on this drive. Because we have a lot of mails in our accounts, the cache was about 50-100MB for some users, and users with a lot mail accounts had very often timeouts. This was due to performance problems on our network storage. Sometimes it also works to delete thunderbird´s cache files. Then it has to download all the headers again (bad with bad performing network storage :-/), but it seems that these cache files get corrupted from time to time and this also produces timeouts. kind regards Andreas -- Computer Bild Tarifsieger!

[Dovecot] Dovecot and Pipermail integration
by Ricardo Ramirez 09 Mar '09

09 Mar '09

Hello, I have a standard Mailman/Pipermail install with mboxes at MM_HOME/archives/public/listname.mbox/listname.box What's the best way to export these via IMAP using Dovecot 1.0rc15 on Debian etch? I know I could make a namespace with MM_HOME/archives/public/ but that would result in half of the directories being exported (the ones containing the HTML archives) being unusable. I could also create another directory and symlink all the mboxes in there but that seems wrong. Preferably, I'd like to have something like a namespace with a mail location of MM_HOME/archives/public/*.mbox/ but that doesn't work with v1.0 Ricardo

[Dovecot] system & virtual setup
by Jim Pazarena 07 Mar '09

07 Mar '09

No one replied to my original email, and I was hoping if I re-phrase my question I can get an answer. I would like dovecot to provide system email (located at /mail/%u with system password and /home/%u) and also virtual email (/u/mail/VIRTUAL/%d/%u with password found at /u/exim/etc/VIRTUAL/%d/passwd). NO home space, but I would consider /home/%d/%u This I think has something to do with namespace, but the docs are too vague for me to understand. Can anyone help me out? I would very much appreciate it. I would even consider PAYING someone to set me straight. I am looking to migrate away from vm-pop3d. initially with POP3 and ultimately into IMAP. Thanks!

[Dovecot] verbose_proctitle doesn't work?
by Mark Hedges 05 Mar '09

05 Mar '09

How is verbose_proctitle supposed to work? I set it in the config but I don't see anything particularly verbose while the mailbox is connected. This is while the connection is open, immediately after deleting a message, before closing the connection. Same for IMAP and POP tests. # `ps axu | grep dove` # root 20392 0.0 0.0 1888 540 ? Ss 12:45 0:00 /usr/sbin/dovecot # root 20393 0.0 0.0 8112 1968 ? S 12:45 0:00 dovecot-auth # root 20395 0.0 0.0 8116 2048 ? S 12:45 0:00 dovecot-auth -w # dovecot 20396 0.0 0.0 4828 1520 ?

[Dovecot] imap locking spool?
by Mark Hedges 05 Mar '09

05 Mar '09

How does IMAP lock the /var/spool/mail/user file? Here's my problem: I'm writing a script to expire old or oversize mail through a series of archive folders. I don't want to take the whole server down to do this, nor does it seem like I would have to lock the user out entirely if I can manage to emulate the locks correctly. I am able to lock /var/spool/mail/user (and ~user/mail/*) from procmail, dovecot popmail, and openwebmail using dotlocks. What do I do to prevent dovecot imap from writing the spool and various mbox files while my script is running? Just posix fcntl on the various files? I'm trying to use Mail::Box in perl which I'm having some problems with, corresponding with the developer, but if anyone has any easy way out I would appreciate the advice very much! Mark

[Dovecot] failed assertion in 1.1.8: istream.c: line 81
by Alan Ferrency 05 Mar '09

05 Mar '09

Hello, We're having a problem in Dovecot 1.1.8 with a failed assertion on certain mbox format mailboxes. It happens both with deliver when it attempts to delier to the mailbox, and with IMAP connections for the affected box (though I'm not sure what they're doing at the time). Mar 3 12:55:26 <snip> dovecot: Panic: IMAP(<snip>): file istream.c: line 81 (i_stream_read): assertion failed: (_stream->skip != _stream->pos) This is on FreeBSD 6.2, without any nfs. The IMAP client is Squirrel Mail, but as I said, the assertion occurs with deliver as well. Apparently, moving the inbox out of the way fixed the problem for a while, but then it came back. Clearing out the dovecot index files seemed not to have any effect. I have a core dump available for deliver; here's a backtrace: #0 0x282bbecb in kill () from /lib/libc.so.6 #1 0x282bbe68 in raise () from /lib/libc.so.6 #2 0x282bab78 in abort () from /lib/libc.so.6 #3 0x080b7ad8 in default_fatal_finish (type=LOG_TYPE_PANIC, status=0) at failures.c:150 #4 0x080b7dbb in i_syslog_fatal_handler (type=LOG_TYPE_PANIC, status=0, fmt=0x80ca9a0 "file %s: line %d (%s): assertion failed: (%s)", args=0xbfbfe2a4 "{\215\r\bQ") at failures.c:308 #5 0x080b7c37 in i_panic (format=0x80ca9a0 "file %s: line %d (%s): assertion failed: (%s)") at failures.c:197 #6 0x080bb8a1 in i_stream_read (stream=0x8102e28) at istream.c:93 #7 0x080bbd3d in i_stream_read_data (stream=0x8102e28, data_r=0xbfbfe350, size_r=0xbfbfe354, threshold=0) at istream.c:322 #8 0x0806d85b in istream_raw_mbox_get_body_size (stream=0x8102e28, expected_body_size=11013) at istream-raw-mbox.c:562 #9 0x080736dd in mbox_sync_do (sync_ctx=0xbfbfe640, flags=0) at mbox-sync.c:151 #10 0x08075700 in mbox_sync (mbox=0x8103028, flags=0) at mbox-sync.c:1833 #11 0x08070001 in mbox_save_init (_t=0x80f2980, flags=0, keywords=0x0, received_date=1236108538, timezone_offset=0, from_envelope=0x80e6100 "<snip>", input=0x80f6f28, dest_mail=0x8106028, ctx_r=0x0) at mbox-save.c:318 #12 0x282ee17f in quota_save_init (t=0x80f2980, flags=0, keywords=0x0, received_date=-1, timezone_offset=0, from_envelope=0x80e6100 "<snip>", input=0x80f6f28, dest_mail=0x8106028, ctx_r=0xbfbfe9f0) at quota-storage.c:236 #13 0x0808e36d in mailbox_save_init (t=0x5, flags=0, keywords=0x0, received_date=-1, timezone_offset=0, from_envelope=0x80e6100 "<snip>", input=0x80f6f28, dest_mail=0x8106028, ctx_r=0xbfbfe9f0) at mail-storage.c:726 #14 0x0808c34a in mail_storage_copy (t=0x80f2980, mail=0xbfbfe9f0, flags=0, keywords=0x0, dest_mail=0x8106028) at mail-copy.c:28 #15 0x282ee08a in quota_copy (t=0x80f2980, mail=0x80fd028, flags=0, keywords=0x0, dest_mail=0x8106028) at quota-storage.c:180 #16 0x080590a4 in deliver_save (namespaces=0x80f7028, storage_r=0xbfbfeb60, mailbox=0x80d0eeb "INBOX", mail=0x80fd028, flags=0, keywords=0x0) at deliver.c:237 #17 0x0805a90c in main (argc=5, argv=0xbfbfec14) at deliver.c:1093 Does anyone have any clues on how to debug this further? I wonder if the original bug reporter removed both the mailbox and the index files at the same time; the current explanation is less than satisfactory. Thanks, Alan Ferrency pair Networks, Inc.

[Dovecot] deliver to root
by Philipp Kolmann 05 Mar '09

Hi, we use dovecot 1.1.11 on a RH Server with sendmail. Local delivery is done with deliver: Mlocal, P=/usr/local/libexec/dovecot/deliver, F=lsDFMAw5:/|@qSPfhn9, S=EnvFromL/HdrFromL, R=EnvToL/HdrToL, T=DNS/RFC822/X-Unix, A=deliver -d $u This setup works without issues for us, but mail to root has a problem with deliver: deliver(root): Mar 04 16:31:31 Error: userdb(root) returned 0 as uid deliver(root): Mar 04 16:31:31 Error: userdb(root) returned 0 as gid deliver(root): Mar 04 16:31:31 Error: User root is missing UID (set mail_uid) Is it generally not possible to use deliver to deliver mail to root?

[Dovecot] set \Seen flag on mail
by J.P. Trosclair 04 Mar '09

04 Mar '09

I'm looking for a way to set the \Seen flag on certain mail no matter what. Currently I'm using a global sieve script to do this. From what I've read, there is no way to enforce the global script if the user creates their own sieve script. More details: I have a postfix transport that along with sender_bcc_maps and recipient_bcc_maps uses deliver to create a read only archive of user's mail. The mail intended to be archived is stored in a per user imap folder called "Archives" that uses the ACL plugin to make the messages there read only. In addition to that, I want the mail marked as \Seen upon delivery so that user's who subscribe to the Arhives folder don't see new mail indications and what not when mail is delivered there. Is there a better way to set the \Seen flag other than the global sieve script since it can be overridden by the user? -- J.P. Trosclair

[Dovecot] tls and auth plain login
by Bradley Giesbrecht 04 Mar '09

04 Mar '09

Hello List, I want to allow plain text passwords only on ssl/tls. Is it possible to have: auth default { mechanisms = cram-md5 ntlm ...... } and then over-ride this when connection is ssl/tls to allow plain and login? I have tried adding "mechanisms = plain login cram-md5 ntlm" to "protocol imaps{}" as an example but I get an error that the protocol does not exist. I read somewhere today that dovecot enables plain automatically over secure connections (ssl/tls) but I'm not seeing it. Also, "auth default" suggests that "auth something_else" is possible. I'm probably just doing a poor job of research but I'm not finding the answers I'm seeking.

[Dovecot] problems with dotlock
by Mark Hedges 03 Mar '09

03 Mar '09

I have to make dotlock work because this openwebmail thing only supports one of dotlock or flock, but procmail delivery does dotlock and fcntl. procmail correctly creates a dotlock file in /var/spool/mail/username.lock when delivering, I can watch this with `while :; do ls -la | grep lock; done`. It works fine when lock_method=fcntl, but no dotlock file shows up in /var/spool/mail. mbox_write_locks are working correctly with mbox_write_locks = dotlock fcntl, the dotlock file shows up in the user's mail directory. However, dotlocking /var/spool/mail doesn't work: $ ls -la /var/spool/mail total 44 drwxrwxr-x 2 root mail 4096 Feb 25 17:39 . $ grep mail_privileged_group /etc/mail/dovecot.conf mail_privileged_group = mail Feb 25 17:45:45 anubis dovecot: POP3(despam_test_anubis): Effective uid=511, gid=100 Feb 25 17:45:45 anubis dovecot: POP3(despam_test_anubis): mbox: data=/home/anubis/despam_test_anubis/mail:INBOX=/var/spool/mail/despam_test_anubis Feb 25 17:45:45 anubis dovecot: POP3(despam_test_anubis): mbox: root=/home/anubis/despam_test_anubis/mail, index=/home/anubis/despam_test_anubis/mail, inbox=/var/spool/mail/despam_test_anubis Feb 25 17:45:45 anubis dovecot: POP3(despam_test_anubis): file_lock_dotlock() failed with mbox file /var/spool/mail/despam_test_anubis: Permission denied Feb 25 17:45:45 anubis dovecot: POP3(despam_test_anubis): Couldn't open INBOX: Internal error occurred.

[Dovecot] GSSAPI cross-realm still broken
by Bryan Jacobs 03 Mar '09

03 Mar '09

I've been trying to track down some problems with Dovecot in a Kerberos 5 cross-realm environment, and there seem to be a few issues. LOGIN/PLAIN work fine using pam_krb5, but GSSAPI is a bit harder to handle. On line 436 of src/auth/mech-gssapi.c, the authn_name and the authz_name are compared using gss_compare_name. This dates back to the message at: http://dovecot.org/pipermail/dovecot/2005-October/009615.html While everything within that message is true, as things stand, Dovecot is unusable in a cross-realm environment. When cross-realm tickets are used, the authn_name is "username@REALM" and the authz_name is "username" (or vice versa, I don't remember). The attached patch causes dovecot to display these two values in human-readable format to illustrate the issue. Because these two GSS names differ, Dovecot refuses to allow access in spite of the fact that krb5_kuserok would return TRUE. I am not the only one to have noticed this problem: http://dovecot.org/pipermail/dovecot/2007-July/023868.html http://dovecot.org/pipermail/dovecot/2007-October/026027.html Might I suggest that some more robust security checking be done instead of abusing gss_compare_name like this? I don't know how to do this using GSSAPI, but on the Kerberos side Heimdal provides the function krb5_kuserok. Dovecot could also just have a configurable file listing acceptable krb5 principals (preferably in .k5login syntax) and check that both auth_name and authz_name are in the list. Bryan Jacobs

[Dovecot] Anyone know or have a perl, c/c++ script?
by Brandon Lamb 03 Mar '09

03 Mar '09

Hello all, Im hoping maybe someone on this list has already looked for or built something similiar. Basically from what I can tell, phps imap libraries or whatever dont support setting custom keywords. So I am wondering if someone has a library or script that can take a username, domain, password, folder, uid and flag to set so that my webmail app can call this to set imap keywords. So far my google searching isnt turning up anything, but searching for the word keyword doesnt really help.

[Dovecot] Seperate auth per protocol (pop3/imap)
by Guy 03 Mar '09

03 Mar '09

Hi, During discussions with the boss we've speculated about having users having only specific services available. One of the ideas was to have users being able to specify if they wanted POP3 or IMAP and whether we could limit their access to one or the other server side. We use MySQL for the userdb and passdb lookups at the moment. Is it possible to specify separate auth files with different MySQL lookups per protocol? Thanks Guy -- Don't just do something...sit there!

by Lorenzo Bettini 02 Mar '09

02 Mar '09

We've been using an imap(s) dovecot server for a while on an ubuntu 8.04.2 and we noted that tags set by thunderbird ("important", "to do", etc.) are almost always lost, i.e., when connecting to the same imap account from another machine, the tags are not there anymore... this always happens for the Inbox, and seldomly for other imap folders... anyone else experiencing this? Note that the same problem does not arise with other imap server accounts... thanks in advance Lorenzo -- Lorenzo Bettini, PhD in Computer Science, DI, Univ.

[Dovecot] Maildir format use question
by Rick Romero 02 Mar '09

02 Mar '09

Hey all, I've got a couple servers using Maildir format. As I understand it from a simple perspective, 'new' contains newly delivered messages, and 'cur' contains messages that have been 'handled'. I like to keep things simple for users, so rather than have 'Spam', 'Junk' 'ToLearn' and other possibly confusing folders, what I thought I would do is scan their .Spam/cur folder for mail that was older than an hour (based on file atime(?) stamp) and feed that through SpamAssassin. The idea being that anything in 'cur' would: 1. have been moved there by the user. 2. be recently read, and I think if it were innocent, would be handled within an hour 3. Not contain newly delivered, unread mail. This is actually what I see when I view my Spam folder through Evolution. If I use a PHP webclient - either Horde or Roundcube (I've captured the debugs if you'd like them), then a simple view of the Spam folder causes the files to be moved from new/ to cur/. They are updated with the :2, - but since nothing was actually done, no flags are added. So I'm left with a quandry. I guess the simple question is, Should mail in cur, EVER not have a flag? I suppose if it were marked as UNSEEN after being SEEN, that's possible. So I just answered myself there :) Is it possible to have Dovecot NOT move a file from new/ to cur/ until a flag has been assigned to the mail? Just from a, possible, performance standpoint - it seems when accessing an INBOX from a PHP webmail system with MANY new mails, there is an unnecessary(?) mass move of these files to another folder. Thoughts? Rick

[Dovecot] Forwarding with Dovecot
by Sawtooth500 02 Mar '09

02 Mar '09

I'm using Dovecot with Postfix as my MTA I need to set up forwarding with Dovecot. I create a .forward file in my user's home directory, and in the .forward file I put destination_email_address email(a)example.com. Well, it got delivered to the forwarded email just fine. But the sender also got an undeliverable email from the dovecot mailbox and a copy was not saved in the dovecot mailbox. I need emails forwarded, and a copy saved in the dovecot mailbox. Thanks in advance for the help! -- View this message in context: http://www.nabble.com/Forwarding-with-Dovecot-tp22244316p22244316.html Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Remote storage
by Daniel L. Miller 01 Mar '09

01 Mar '09

What options are available for remote storage, i.e. storage devices directly mounted on the machine running Dovecot? I've seen discussions of NFS usage - but my experiences with NFS in times past have been poor. CIFS has worked well for me for non-mail use - would this be suitable? Or is there another method I've not considered? -- Daniel

[Dovecot] Compilation Issue on Old Boxes with macro in src/master/main.c
by Kevin A. McGrail 28 Feb '09

28 Feb '09

I'm throwing an error compiling with a custom-compiled gcc 3.2.3 on one box. The configuration string is CC=/usr/local/gcc3.2.3/bin/gcc CPPFLAGS=-I/usr/local/ssl/include LDFLAGS=-L/usr/local/ssl/lib ./configure --with-ssl=openssl --with-ssldir=/usr/local/ssl/certs --with-pam --with-pop3d --sysconfdir=/etc --localstatedir=/var I've used this to compile on other older boxes with success. And I compared the command lines and they are identical. This is the error I get with src/master/main.c main.c:365:1: directives may not be used inside a macro argument main.c:364:16: unterminated argument list invoking macro "printf" main.c: In function `print_build_options': main.c:372: syntax error before string constant Changing the function to a simpler function without the ifdef's resolves the issue and dovecot compiles. I would really like to know why two boxes with the same compiler are failing on one but not the other. Perhaps there's some program or library or preprocessor or path or something out of whack. Especially since using gcc 2.96 on the same box works! However, I since this is a simple options output routine and (from my cursory read) there may be some standards issue with this technique, I've also patched the issue. http://www.peregrinehw.com/downloads/dovecot/dovecot-1.1.11-build_options_m… Thoughts?

[Dovecot] allow_nets
by CJ Teets 28 Feb '09

28 Feb '09

Hello, Im using Ubuntu 8.10 with Dovecot 1.0.10. I am using passwd files, not a MySQL database. I have 2 files, a "users" file, and a "passwd" file. I have added: allow_nets=10.1.10.1 to the end of a specific users entry in the users file. When that user tries to login, I get the following in the logs: dovecot: 2009-02-28 09:06:59 Error: IMAP(bob(a)mydomain.com): Ambiguous mail location setting, don't know what to do with it: allow_nets=10.1.10.1 (try prefixing it with mbox: or maildir:) dovecot: 2009-02-28 09:06:59 Error: IMAP(boo(a)mydomain.com): Mail storage creation failed with mail_location: allow_nets=10.1.10.1 dovecot: 2009-02-28 09:06:59 Error: child 4174 (imap) returned error 89 here is the line from my users file: bob@mydomain.com::5000:5000::/home/vmail/ mydomain.com/:/bin/false::allow_nets=10.1.10.1 here is the corresponding line from the passwd file: bob@oldschoolpunk.com:$1$evcHgrbC$BuyQRCspMzTpD8zkphxo0/ My goal is, that I want to allow this user to check email ONLY from the IP specified (i.e. 10.1.10.1) I just can't seem to get this working... Am I going about something the wrong way? Thanks!

[Dovecot] Custom flags in v1.0.15
by Pascal Mouret 28 Feb '09

28 Feb '09

Hello all, I'm having problems with setting custom flags on a dovecot imap setup, with mbox mail store. I was running v1.0rc15 on a Debian Etch box, upgraded recently to v1.0.15, but nothing changed. The problem : I read my mail using IMAP. In Thunderbird (various versions, current one being v2.0.0.19), I can set various message flags (Important, Personal, Work, ... mapped to IMAP as $Label4,$ $Label3, $Label2, ...). I read my mail from several machines, but all changes made on the message flags from one machine won't appear on the others !? Still I've read that those flags are supported in Dovecot. Actually, I logged the IMAP traffic, and saw that Dovecot claims to "handle" them. For instance, I added a flag to a message : Thunderbird > 621 uid store 35150 +FLAGS ($label4) Dovecot > * 6716 FETCH (UID 35150 FLAGS (\Seen \Recent $Label4)) Now, if I close TB, so that changes are written to the mbox file, and if I open that file on a the server with any text editor, the 'X-Keywords' line doesn't appear !? And as a matter of a fact, if I read my mail from any other machine, the flag isn't set ! Anyone knows where the problem can be ? Do I need to upgrade to v1.1 ? Or are custom flags actually supported in v1.0 (which I believe is the case) ? I browsed through the internet and searched the archives of this mailing list but didn't find any clue ...

[Dovecot] Dovecot + Postfix Mail Forwarding Question
by Taras Hryniw 28 Feb '09

28 Feb '09

I have dovecot and postfix set up on debian lenny. Squirrelmail is used to access the mail. I put a .forward file in my user's home directory, and that sure gets the job done of forwarding email, but I need a copy saved on the local machine as well. How do I do that?

This: Feb 16 10:05:56 server dovecot: Panic: IMAP(user): file istream-tee.c: line 144 (i_stream_tee_read): assertion failed: (ret > 0) auth-worker died. That happened with Dovecot 1.1.4, 1.1.7 and 1.1.11, 1.1.7 was not with me, was with another user I found, on some mailing list. The problem occurred when copying or deleting messages, sometimes even viewing (Webmail). Since it's a production server, I compiled the latest 1.0.x and I'm using it. This particular server was running Ubuntu 8.04 (the default package is 1.0.x) and I upgraded to 8.10 (the default package is 1.1.x). > > > Is it possible to have Dovecot on one machine serving two different domains? > > Set up how? Do you want to use user@domain style usernames, or do you > want Dovecot to detect the domain based on the server's IP address? One dovecot server which receives mail to two domains and does not forward the mail anywhere, it's the final destination for the two of them. I already have usernames that are unique, by using Dovecot variables I have username~domain.org as the actual username/mailbox name. I want to have two mailbox roots, this way, even knowing that mailbox names are unique (john~domain.org != john~anotherdomain.org) and when authenticating (from what you wrote down here about passdb) john(a)domain.org will not be confused with john(a)anotherdomain.org, even so, I want all mailboxes from one domain to sit on a different mailbox root. > > > Is is possible to set a LDAP config to one domain and another > > LDAP config to the other (the auth part, I wan't users to reside > > on different bases on my LDAP tree, so search bases need to be > > different) > > Yes. You can just create two passdb ldap {}s. Ok, so, I have 3 aspects to consider: a) When mail arrives b) When user logs in to check mail c) Where mailboxes are located a) Since I can make mailbox names unique with Dovecot variables (mailbox name is "susan~domain.org" which is different from susan~anotherdomain.org) when mail arrives, the mail message will be saved to the correct mailbox (even if I have, under the same mailbox root, two users with "susan" as the login, but from different domains). b) Since you said, on Dovecot 1.0.x, I can have two passdb ldap{}'s, when the user logs in, he/she will be redirect to the right mailbox, not the "other susan". c) Ok, the two above give me the possibility to have all mailboxes, from the two domains, under the same mailbox root, users will be unique no matter the scenario (mail arriving, user checking mail), BUT, I would like to keep them separated anyways, is that possible to force that? > thanks! = Miata Convertible Tops Buy manufacturer direct from gahh, leader in high-quality convertible tops using original materials and attachments.

[Dovecot] Quota + Sieve
by Linux Advocate 27 Feb '09

27 Feb '09

Thanx to everybody's help , i have got a working combination of; - dovecot LDA - smtp auth thru dovecot sasl - postfix - virtual users in mysql - postfixadmin - thunderbird as the email client Just 2 additional questions - A. Sieve .............. With the imap filters in thunderbird, do i need to use sieve in dovecot? my initial observations/ findings say "no"? B. Quota ............. If i have not set quota in dovecot or postfix ( no quota related configuration ), may i then assume, the users have "unlimited storage" , limited only by the hardware/filesystem? I would like to have this feature ( just like unlimited storage in yahoo ) and just have a cron script running regularly to delete old emails ( for middle level, low level users ). Is such a strategy ok? regards, mgomez

From there it didn't take long to figure out that something had changed with update of Dovecot that no longer allowed this configuration line to work: mail_location: ~/Maildir and both in dovecot.conf and log I was warned to add the prefix "maildir"" With this everything seems to be fixed. I don't know whether this would be considered any kind of bug. The Debian package allowed me to upgrade Dovecot without warning me that the rules for mail_location had changed.

One way I can do this is to set up a mailbox and then have an application that checks to see if there's mail and then processes it. (Old school Unix script) Is there a way to set it up with dovecot? (Cleaner solution) Thx -Mike

[Dovecot] exim4 + dovecot + SquirrelMail virtualhosted on Debian
by Tim Legg 25 Feb '09

25 Feb '09

Hello, I have a Debian machine that is virtual-hosting 6 domains with exim4. I finally got exim4 working well enough where I can send and receive mail using the mail command on my machine. I would eventually like to have SquirrelMail (which requires IMAP) working on my website. For whatever reason, exim4 doesn't seem to support IMAP. I found out that Dovecot is a prominent IMAP server. So I installed the most current Dovecot package (1.0.rc15) in Debian. Something is broken though... As I log into SquirrelMail, I get an error message "Error connecting to IMAP server: localhost. 111 : Connection refused". To investigate, I decided to telnet localhost on port 143 and found out that yes, the connection is in fact refused. So what do I need to do in order to have dovecot listen on port 143? Also, I noticed when I restart dovecot... debian:/etc/dovecot# /etc/init.d/dovecot restart Restarting mail server: dovecotError: Can't use mail executable /usr/lib/dovecot/imap: No such file or directory I hope this isn't a serious problem. Thanks Tim Legg

[Dovecot] imap SORT core dumps on beta1
by jsiegle＠psu.edu 25 Feb '09

25 Feb '09

Steps to reproduce: 0 login userid password 1 select myfavoritemailbox 2 sort (FROM) UTF-8 ALL I tested alpha5 and it works fine. Here is the trace of beta1. I see many adds in revision 8726(hg annotate mail-storage.c), but that line number(674) is very old. So it might be a local problem. Here is what dbx "where" says about what happened. mailbox_header_lookup_init(box = (nil), headers = 0x0ffffffffffff260), line 674 in "mail-storage.c" wanted_fields_get(box = (nil), sort_program = 0x0ffffffffffff3a0, wanted_fields_r = 0x0ffffffffffff308, headers_ctx_r = 0x0ffffffffffff310), line 518 in "imap-search.c" imap_search_start(ctx = 0x0000000110021c70, sargs = 0x00000001100848b8, sort_program = 0x0ffffffffffff3a0), line 536 in "imap-search.c" cmd_sort(cmd = 0x0000000110021b58), line 136 in "cmd-sort.c" client_command_input(cmd = 0x0000000110021b58), line 603 in "client.c" client_command_input(cmd = 0x0000000110021b58), line 652 in "client.c" client_handle_next_command(client = 0x00000001100216d0, remove_io_r = 0x0ffffffffffff621), line 693 in "client.c" unnamed block in client_handle_input(client = 0x00000001100216d0), line 703 in "client.c" client_handle_input(client = 0x00000001100216d0), line 703 in "client.c" client_input(client = 0x00000001100216d0), line 748 in "client.c" io_loop_handler_run(ioloop = 0x000000011001f850), line 203 in "ioloop-poll.c" io_loop_run(ioloop = 0x000000011001f850), line 338 in "ioloop.c" main(argc = 1, argv = 0x0ffffffffffff918, envp = 0x0ffffffffffff928), line 315 in "main.c" (dbx) quit Thanks, Jonathan

All fail but 777. ps -ef|grep exim shows that exim is run by user 101. A look into /etc/group reveals the user as libuuid. Debian-exim is user 103. Could this be what is causing my problems? How do I change what user exim is run as? -- Daniel

[Dovecot] Securing mailboxes and passwords
by Daniel Aleksandersen 25 Feb '09

25 Feb '09

Hi list I am just experimenting with seting up my own email server. I want some tips and hints on how to secure my setup to prevent unauthorised assess to my email. I have read through the wiki and have not found many tips. I hope to improve the wiki with tips gathered from the emailing list. :-) A basic measurement I could take right now would be to set more secure file premissions on my setup. My setup is based on http://wiki.dovecot.org/HowTo/VirtualhostingWithExim with a few addittions: fetchmail and exim4 deliver mail to my maildir and dovecot grants me access through imap. dovecot authenticates against /home/postmaster/passwd.digest and ./passwd.cram -- Daniel Aleksandersen <aleksandersen(a)runbox.no>

[Dovecot] Calling dovecot deliver from procmail
by Harry Lachanas 25 Feb '09

25 Feb '09

I came up with this trick That is Since my previous mail server had a bunch of complex procmail recipies and I am not sure that I can turn them into sieve scripts I am calling dovecot deliver to drop mail in it's final $DEFAULT destination. :0 | /some/path/dovecot/deliver in order to update the index, control files etc upon delivery time. So far in my "tests" it works. But I wonder if this is wise or not. Regards, Harry.

[Dovecot] Dovecot problem after last Debian sid update
by Paul Scott 25 Feb '09

25 Feb '09

Hi All, After upgrading dovecot for sid Thunderbird no longer displays the contents of any emails I have had a working IMAP setup for as much as a year even though I don't understand dovecot configuration well enough to know how I got it to go in the first place. Here is the output of dovecot -n # 1.1.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-1-vserver-686 i686 Debian 5.0 log_timestamp: %Y-%m-%d %H:%M:%S disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_location: ~/Maildir auth default: passdb: driver: passwd-file args: /etc/passwd.dovecot userdb: driver: passwd TIA for any clues as what to do next.

[Dovecot] OT: Fixing Messages To Be RFC 2822 Compliant
by Neil 25 Feb '09

25 Feb '09

So....apparently I have some messages which are not RFC compliant sitting in my mailboxes (mostly older ones), and I have some software which is refusing to handle such messages. 1. Does anyone know of a nice way to verify that all my messages are compliant/find those that aren't? (I suppose I could use the existing failing software, but I was hoping for something a little more robust...) 2. Does anyone know of any tools that will do The Right Thing as far as fixing these messages are concerned? Googling didn't turn up much for me, but maybe I wasn't hitting the right terms ("RFC message repair", "fix email message", etc.). Thanks.

[Dovecot] Read-Only IMAP
by Neil 24 Feb '09

24 Feb '09

Inspired by the "Dovecot as a email storage system" thread... Is there a way to instruct Dovecot go into read-only mode for an account, or a mailbox? Could I maybe fake it by setting perms on the maildir directory to 440?

[Dovecot] Dovecot as a email storage system
by Roderick A. Anderson 24 Feb '09

24 Feb '09

I was thinking about all the old email I have and don't want to get rid of and how much space it is taking on my mail server. The idea came to me to install Dovecot on a server at home then I could drop mail into I want to save. It doesn't need to receive mail except what that is moved to it. Anyone see problems with doing this? Thanks, Rod --

[Dovecot] email stuck in outbox
by barnaby cockcroft 24 Feb '09

24 Feb '09

Can anyone here help me out with a client side Outlook issue? I know outlook is a horrible imap client :( We intermittently have a problem where mail gets "stuck" in Outlook users' outboxes. Might have anything to do with dovecot? Is there anyway I can troubleshoot this server side? Are there any settings I can tweak? We have a new and an old dovecot server (see below) and both exhibit the same behavior (occasionally) for heavy mail users. We haven't ruled out a layer 2 issue but nor have we found one.... If anyone has any ideas (other than suggesting a different email client), they'd be much appreciated. Dovecot version(s) 1.19 & 0.99.11 Configuration from 1.19: # 1.1.9: /usr/local/etc/dovecot.conf # OS: Linux 2.6.9-78.0.13.ELsmp i686 Red Hat Enterprise Linux ES release 4 (Nahant Update 7) ext3 syslog_facility: local0 ssl_cert_file: /usr/local/etc/ssl/**************** ssl_key_file: /usr/local/etc/ssl/***************** disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login mail_location: mbox:/home/%u/mail:INBOX=/var/spool/mail/%u mbox_write_locks: fcntl auth default: debug: yes passdb: driver: pam userdb: driver: passwd

[Dovecot] Broken dovecot-uidlist files
by Ulrich Zehl 24 Feb '09

24 Feb '09

I have just upgraded to 1.1.8, hoping to fix these types of errors: Jan 20 10:39:27 laura deliver(xxxxxx(a)example.net): Broken file /srv/storage/mail/store/net/example/xx/xxxxxx/Maildir/dovecot-uidlist line 156: Invalid data: Jan 20 10:41:19 laura dovecot: POP3(yy.yy(a)example.at): Broken file /srv/storage/mail/store/at/example/yy.yy/Maildir/dovecot-uidlist line 2: Invalid data: Unfortunately, they still pop up. Since I suspect these errors to be responsible for customers complaining about downloading mails twice, I'd like to fix them. Our setup has multiple servers sharing the same NFS-mounted directory for maildirs and indexes; we have set mmap_disable = yes dotlock_use_excl = yes fsync_disable = no mail_nfs_index = yes lock_method = fcntl As far as I can tell, for at least one of these errors, there was no concurrent access to the mailbox in question. What can I do to solve this problem, or to analyze it further? Ulrich

This is with respect to an error that I am facing in dovecot. The error is that is seen in logs is "Feb 23 00:04:46 mailblade1 dovecot: IMAP(USERNAME): /indexes/USERNAME/.INBOX/dovecot-uidlist: Duplicate file entry at line 7: 1234776125.M559298P3988.s2o.qlc.co.in,S=13111,W=13470:2, (uid 94277 -> 97805)" This error is seen for multiple users.

[Dovecot] Postfix LDA vs the Dovecot LDA + other quetions
by Linux Advocate 24 Feb '09

24 Feb '09

Guys , 1. What is the benefit of using Dovecot' LDA as compared to postfix's LDA? Will there be better performance? And along the same vein, 2. What is the benefit of using Dovecot's SASL as compared to Cyrus SASL? Is there better performance? 3. Quota Management ( Creating, enforcing, notifying ) - is it done thru dovecot or postfix or are both needed? Regards, mgomez

I'm trying to integrate both the new sieve implementation and managesieve into pkgsrc. Managesieve seems to need some dovecot libraries that dovecot doesn't install (lib-storage/libstorage.a, lib-auth/libauth.a, lib-imap/libimap.a, lib-index/libindex.a, lib-mail/libmail.a, lib-charset/libcharset.a, lib-dict/libdict.a and lib-charset/libcharset.a). There seems to be no provision in pkgsrc for the build of a package needing the work directory of the build of another package. Would it make sense for dovecot to install those libraries?

[Dovecot] sieve-test again
by Ian P. Christian 23 Feb '09

23 Feb '09

I'm not sure what it is I'm doing wrong here, perhaps my 'test' mail is not in the format expected by sieve-test. The 'test' file is a file taken directly from a dovecot maildir - so is in the normal format of having headers, a new line, then the body. There is nothing exceptional about this email. Notice how the header below is 'innocent', however it appears that the test is ignoring this header. # grep DSPAM-Res test X-DSPAM-Result: Innocent # cat sievetest require ["regex", "fileinto","envelope","reject","vacation","relational","comparator-i;ascii-numeric"]; if header :contains "X-DSPAM-Result" "Innocent" { fileinto "moo"; stop; } # sieve-test -c ./sievetest ./test Performed actions: (none) Implicit keep: * store message in folder: INBOX Info: final result: success I don't think it's this header, but rather *all* headers, as the following check also appears to fail. if header :contains "To" "o" { fileinto "Spam"; stop; } Am I mis-using the tool? Thanks, Ian

Hello all. I use dovecot in combination with postfix, postfixadmin for virtual users. Deliver to the mailbox now is done by postfix Now i want to enable quota's and therefor i need dovecot deliver. Can i just switch to dovecot deliver? Or must i first do some prrperations in the mailboxes. regards -- _______________________ *Johan Hendriks* *Schavemaker Transport* Tel: +31 (0)251 229098 Fax: +31 (0)251 212016 email: j.hendriks(a)schavemaker.com <mailto:j.hendriks@schavemaker.com> web: http://www.schavemaker.com _______________________ /Confidentiality Notice: The information in this document may be confidential.

[Dovecot] lda catchall
by Stéphane Cottin 23 Feb '09

23 Feb '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I'm using dovecot lda in a qmail / vpopmail testing environnement. I would like to replace vpopmail lda with dovecot's one , because of quotas , sieve filers, indexing while delivering ... Everything is working great, except the catchall. If I want to bounce, a first line like "# bounce-no-mailbox" in the .qmail file works, without this line, emails to unknown addresses are deferred and stay in the queue, because they are deliverable for qmail, but not for dovecot lda. How can I set a catchall email address for dovecot lda ? thx Stéphane Cottin -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkmixCcACgkQNgQUYqHIqqvttQCfcNBLd9Qo06g5nMcrfZAwVlpv WegAnj7jIA/XFJWmt/2jkg1sxRYKRaI7 =JTTV -----END PGP SIGNATURE-----

[Dovecot] IMAP ACLs and global ACLs in v1.2
by Timo Sirainen 23 Feb '09

23 Feb '09

I just committed code for IMAP ACL support based on the code from Kolab people. I did quite large changes though. I also changed how global ACLs are handled. Previously local ACLs could override global ACLs, but now that users are able to modify the ACLs I think it should be the other way around. From what I've heard global ACLs are typically added for things like 1) disallowing user from doing something in specific mailboxes such as expunge messages, 2) giving a specific master user access to some mailboxes ONLY, such as voicemail. For 1) case a user really shouldn't be able to grant himself privileges back but still should be able to share the mailbox to others (so the global ACL should have 'a' privilege). For 2) case a user shouldn't be able to remove privileges from the voicemail. So now the user can freely update the local ACLs in whatever way he wants. But in the end if there are any global ACLs, all the local ACLs for those identifiers are ignored. Also local negative identifiers are ignored, so that e.g. global "user=foo lr" can't be disabled by a local "-user=foo lr" ACL. I guess I should update the Wiki ACL page about how exactly the ACLs are applied now that they're well in my memory. :) One thing I'm not really sure about is the "owner" handling. IMAP ACL specifications have no such concept. I think many/most other servers simply add a default ACL for the user name directly. It's a useful concept though, especially with the global ACLs. So currently Dovecot replies: x getacl inbox * ACL "inbox" "owner" lrwstiekxacd x OK Getacl completed. But should it just internally convert "owner" to "username" when replying? But then again if there's a separate rule directly for the "username" it breaks. Do any of the existing ACL-capable IMAP clients want to see the username in the ACL reply or can they handle "owner" just fine? Also what about global ACLs? The current code just lists them twice with local ACLs, which is definitely wrong: x getacl foo * ACL "foo" "xx" w "xx" lr "owner" lrwstiekxacd x OK Getacl completed. Perhaps the global ACLs could have a prefix character? Maybe '#'? Which reminds me, the current dovecot-acl file is mapped to IMAP ACLs like this: dovecot-acl : IMAP ACL - anyone : anyone - authenticated : authenticated - owner : owner - user=name : name - group=name : $name - group-override=name : !$name So all global ACLs would get the # prefix, like #anyone, #name, #!$name. Any thoughts? BTW. Listing shared mailboxes still doesn't work. I guess we'll see tomorrow if I still have energy to get that done.

[Dovecot] dovecot auth
by ben 23 Feb '09

Hi, I'm using dovecot with a passdb-file . When I login using : test(a)testdomain.com I notice dovecot strips off the domainname and looks up everything in front of the @ in his passdb-file... So I went on to configure the following in my dovecot.conf : auth_username_format = %u@%d restarted dovecot, but he still strips of the @ and the domainname ... LOG (sorry for f* up format) : dovecot: Feb 21 12:15:08 Info: auth(default): new auth connection: pid=24483 dovecot: Feb 21 12:15:12 Info: auth(default): client in: AUTH 1 PLAIN service=pop3 lip=195.207.136.102 rip=195.207.136.108 lport=110 rport=36132 resp=AGJlbkBpdHV4LmJlAHRlc3QxMjMu dovecot: Feb 21 12:15:12 Info: auth(default): passwd-file(test@testdomain.com@testdomain.com,195.207.136.108): lookup: user=test file=/opt/dovecot/etc/dovecot.passwd dovecot: Feb 21 12:15:12 Info: auth(default): passwd-file(test@testdomain.com@testdomain.com,195.207.136.108): unknown user dovecot: Feb 21 12:15:14 Info: auth(default): client out: FAIL 1 user=test(a)testdomain.com Can someone enlighten me on how to config it so he looks up "test(a)testdomain.com" fully ? thx

[Dovecot] TLS / Dovecot / POP3
by John Espiro 22 Feb '09

22 Feb '09

I am using Thunderbird 2.x as my client, Dovecot on the server (POP3 not IMAP). Currently I have in my conf file: protocols = pop3s pop3 ssl_disable = no ssl_cert_file = /usr/share/ssl/certs/dovecot.pem ssl_key_file = /usr/share/ssl/private/dovecot.pem ssl_parameters_file = /var/run/dovecot/ssl-parameters.dat disable_plaintext_auth = yes login = pop3 In Thunderbird, I have the email server setup to: - Port 110 - TLS Here's my question: If I change protocols = pop3s pop3 to protocols = pop3s I can no longer connect to my mail server via Thunderbird unless I setup Thunderbird to use SSL. Am I doing something wrong? Thanks, John

[Dovecot] Problem with v1.1.10
by Cyrus Rahman 22 Feb '09

22 Feb '09

I've been using 1.1.8 successfully but tried out 1.1.10 this morning. I have a combination of system and virtual users. The system users were unaffected by the change, but the virtual users all lost access to their mail because their home directories, as interpreted by dovecot, moved from user@domain to user@user@domain. The location of the home directory is given to dovecot for virtual users using the static db as uid=vmail gid=vmail home=/var/vmail/%u mail=maildir:~/Inboxdir Were there any changes in this area that might have caused the problem?

[Dovecot] dovecot 1.2 virtual folders question
by Robert Schetterer 22 Feb '09

22 Feb '09

Hi Timo is this possible a possible setup ? for downloading imap folders ( including inbox ) with pop3 controlled by a a dovecot-virtual file in usr/local/virtual/%d/%u/ with content something like that * -Trash -Trash/* -Sent -Sent/* -Drafts -Drafts/* all namespace private { separator = / prefix = "" location=maildir:/usr/local/virtual/%d/%u/:CONTROL=/usr/local/virtual/%d/%u/:INDEX=/usr/local/virtual/%d/%u/ inbox = yes subscriptions = yes list = yes } namespace private { prefix = virtual/ separator = / location = virtual:/usr/local/virtual/%d/%u:LAYOUT=maildir++ inbox = no } it doesnt work yet, but i am nearly sure that i havent understand http://wiki.dovecot.org/Plugins/Virtual perhaps you might bring me on the way background : i want to include a global sieve rule which sorts marked spam mails in a subfolder of inbox called Junk, so that users never can overide it and set perhaps an autoreply by an Sieve rule by incomming mail to inbox to make it possible that pop3 users may fetch sorted Spam mails outta the Junk folder too, i wanna use virtual setup folders Trash , Sent , Drafts are standart folders are standart and should be ignored with that -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

[Dovecot] DIGEST-MD5 user/realm mismatch with Postfix
by Darren Pilgrim 21 Feb '09

21 Feb '09

This is a follow-on to the "SQL field format for digest-md5?" thread. After some additional debugging, I've found the problem is a mismatch in what Dovecot expects and Postfix uses for the user and realm. For a username "user(a)example.com" and password "sekret", Dovecot expects: username = "user" realm = "example.com" but Postfix sends the checksum of: username = "user(a)example.com" realm = "" How do I fix this?

[Dovecot] One Dovecot serving 2 domains - possible?
by k bah 21 Feb '09

21 Feb '09

I'm talking about Dovecot 1.0.x, since 1.1.x showed some problems on some of my servers. -- Is it possible to have Dovecot on one machine serving two different domains? How can I set the mailboxes root to one domain to /dir1/ and to the other domain to /dir2/ ? I want all mailboxes from one domain to reside on a different mailbox root. I use Dovecot LDA. Is is possible to set a LDAP config to one domain and another LDAP config to the other (the auth part, I wan't users to reside on different bases on my LDAP tree, so search bases need to be different) thanks in advance = Scrublade Wipers New, Heavy Duty, wiper design to remove bugs and road slime. http://a8-asy.a8ww.net/a8-ads/adftrclick?redirectid=2b9f0c9f1afcc5e7181028e… -- Powered by Outblaze

[Dovecot] auth-worker always opens PAM session
by Miguel Di Ciurcio Filho 21 Feb '09

21 Feb '09

I'm using Dovecot 1.1.7 on CentOS 5.2. I've changed my passdb from passwd to pam, it works fine, but I've found this messages on /var/log/secure: dovecot-auth: PAM adding faulty module: /lib64/security/pam_limits.so dovecot-auth: PAM unable to dlopen(/lib64/security/pam_limits.so) dovecot-auth: PAM [error: /lib64/security/pam_limits.so: failed to map segment from shared object: Cannot allocate memory] Latter I realized that my auth_process_size was 64. Changed it to 128 and problem solved. But I suspect that dovecot should not be opening sessions, because there is no session=yes on my passdb configuration. According to the docs: args = dovecot [session=yes] [setcred=yes] [failure_show_msg=yes] [cache_key=<key>] [<service name>] session=yes makes Dovecot open and immediately close PAM session. Some PAM plugins need this to work, such as pam_mkhomedir. I checked the source code in passdb-pam.c: struct pam_passdb_module { struct passdb_module module; const char *service_name, *pam_cache_key; unsigned int pam_setcred:1; unsigned int pam_session:1; unsigned int failure_show_msg:1; }; And this: /* -session for backwards compatibility */ if (strcmp(t_args[i], "-session") == 0 || strcmp(t_args[i], "session=yes") == 0) module->pam_session = TRUE; It seams to me that the session is going to be opened anyway, since pam_session is always TRUE. Regards, Miguel
