[Dovecot] inotify max_user instances
by Charles Marcus 07 Jan '14

07 Jan '14

Hello, Timo, last year when you remoted into our server and performed the migration from courier-imap, we ran into this issue, and you solved it by doing: echo 1024 > /proc/sys/fs/inotify/max_user_instances Then you said you were going to solve this permanently by changing the init script... Here is what you said (this is from the skype chat): [2012-06-04 10:40:43 AM] timosirainen: probably put to dovecot init script or something I guess I could manually modify my init script, but I'm clueless as to where.how. The current (gentoo) init script is: > #!/sbin/runscript > # Copyright 1999-2012 Gentoo Foundation > # Distributed under the terms of the GNU General Public License, v2 or > later > # $Header: > /var/cvsroot/gentoo-x86/net-mail/dovecot/files/dovecot.init-r4,v 1.1 > 2012/12/01 10:40:49 eras Exp $ > > extra_started_commands="reload" > > depend() { > need localmount > before postfix > after bootmisc ldap mysql ntp-client ntpd postgresql saslauthd > slapd > use logger net > } > > checkconfig() { > DOVECOT_INSTANCE=${SVCNAME##*.} > if [ -n "${DOVECOT_INSTANCE}" -a "${SVCNAME}" != "dovecot" ]; then > DOVECOT_CONF=/etc/dovecot/dovecot.${DOVECOT_INSTANCE}.conf > else > DOVECOT_CONF=/etc/dovecot/dovecot.conf > fi > if [ ! -e ${DOVECOT_CONF} ]; then > eerror "You will need an ${DOVECOT_CONF} first" > return 1 > fi > if [ -x /usr/sbin/dovecot ]; then > DOVECOT_BASEDIR=$(/usr/sbin/dovecot -c ${DOVECOT_CONF} > -a | grep '^base_dir = ' | sed 's/^base_dir = //') > else > eerror "dovecot not executable" > return 1 > fi > DOVECOT_BASEDIR=${DOVECOT_BASEDIR:-/var/run/dovecot} > DOVECOT_PIDFILE=${DOVECOT_BASEDIR}/master.pid > } > > start() { > checkconfig || return 1 > ebegin "Starting ${SVCNAME}" > start-stop-daemon --start --exec /usr/sbin/dovecot \ > --pidfile "${DOVECOT_PIDFILE}" -- -c "${DOVECOT_CONF}" > eend $? > } > > stop() { > checkconfig || return 1 > ebegin "Stopping ${SVCNAME}" > start-stop-daemon --stop --exec /usr/sbin/dovecot \ > --pidfile "${DOVECOT_PIDFILE}" > eend $? > } > > reload() { > checkconfig || return 1 > ebegin "Reloading ${SVCNAME} configs and restarting auth/login > processes" > start-stop-daemon --signal HUP --exec /usr/sbin/dovecot \ > --pidfile "${DOVECOT_PIDFILE}" > eend $? > } Suggestions? -- Best regards, Charles

[Dovecot] need assistance migrating between apple servers
by Raymond Norton 06 Jan '14

06 Jan '14

I am attempting to move imap folders from an Apple Snow Leopard server to a new Apple Mavericks server. Dovecot --version is not working , but I believe the old server is running dovecot 1.1.2 and can confirm the new one is running 2.2.x. I have tried taring and moving folders, but have not been able to get the transfered messages and folders to show up in user accounts (new messages show up fine). I have attempted to recreate index files, but that has not worked either. The last attempt I made to migrate was to use dsync, but it does not exist on the old server and I do not see a way to install it. What method would work best to migrate or move files and folders from the old server and get them to show up for clients on using the new server? -- Raymond Norton LCTN 952.955.7766 Sent from My Desktop

[Dovecot] [SIEVE] Locking Errors with vnd.dovecot.duplicate Extension
by Daniel Parthey 06 Jan '14

06 Jan '14

Hi, we are running a 4 host setup which each hosts a director+mailbox which is mounted via NFSv4 from a DRBD cluster. * Dovecot upstream release 2.1.16 * Doveadm batch subcommand fix - http://hg.dovecot.org/dovecot-2.1/raw-rev/850b5d8bbcc9 * Pigeonhole release 0.3.4 Now we would like to remove duplicate Mails using the vnd.dovecot.duplicate extension using a SIEVE script like this: require ["vnd.dovecot.duplicate", "fileinto", "mailbox", "regex", "vacation", "variables"]; if duplicate { fileinto :create "Trash"; } But as soon as we start delivering duplicate mails, we're sometimes getting locking errors from the mailbox (which is responsible for the user) according to the director: Dec 27 16:36:30 10.129.3.213 dovecot: lmtp(27975, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:33 10.129.3.213 dovecot: lmtp(27987, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:35 10.129.3.213 dovecot: lmtp(27994, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:36 10.129.3.213 dovecot: lmtp(28011, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:36 10.129.3.213 dovecot: lmtp(28013, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:38 10.129.3.213 dovecot: lmtp(28017, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:39 10.129.3.213 dovecot: lmtp(28025, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:42 10.129.3.213 dovecot: lmtp(28037, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Dec 27 16:36:43 10.129.3.213 dovecot: lmtp(27973, user001(a)example.org) Error: Creating lock file for /mail/dovecot/example.org/user001/.dovecot.lda-dupes timed out in 20 secs Configs and Error log is attached.

[Dovecot] RFE: IMAP LIST Extension for Special-Use Mailboxes
by Patrick Ben Koetter 03 Jan '14

03 Jan '14

Timo, would you consider adding support for "IMAP LIST Extension for Special-Use Mailboxes" <http://www.rfc-editor.org/rfc/rfc6154.txt> any time near in the future? I would really love to get rid of all those folders created by all those different mail clients just because they can't agree to use the same folder for special purpose. Obviously clients need to support it too. Having Dovecot support it certainly would make them adopt the standard sooner. p@rick -- state of mind Digitale Kommunikation http://www.state-of-mind.de Franziskanerstraße 15 Telefon +49 89 3090 4664 81669 München Telefax +49 89 3090 4666 Amtsgericht München Partnerschaftsregister PR 563

[Dovecot] Allow both SSL/993 and STARTTLS/143 connections (secure only)
by Charles Marcus 03 Jan '14

03 Jan '14

Hi all, Ok, up until now, I've only always allowed IMAPS connections to dovecot on port 993. I want to also start allowing clients to user port143+STARTTLS, but I walso want to make sure both ports are locked down to ONLY allow secure connections. So... is disable_plaintext_auth = yes in the main config enough to accomplish this? http://wiki2.dovecot.org/SSL/DovecotConfiguration says: There are a couple of different ways to specify when SSL/TLS is required: * disable_plaintext_auth=yes allows plaintext authentication <http://wiki2.dovecot.org/Authentication/Mechanisms> only when SSL/TLS is used first. * ssl = required requires SSL/TLS also for non-plaintext authentication <http://wiki2.dovecot.org/Authentication/Mechanisms>. * If you have only plaintext mechanisms enabled (auth { mechanisms = plain login } ), you can use either (or both) of the above settings. They behave exactly the same way then and the comments in 10-auth.conf say: # Disable LOGIN command and all other plaintext authentications unless # SSL/TLS is used (LOGINDISABLED capability). Note that if the remote IP # matches the local IP (ie. you're connecting from the same computer), the # connection is considered secure and plaintext authentication is allowed. # See also ssl=required setting. #disable_plaintext_auth = yes These seem to be saying that all I need to do is set either or both (ssl-required and/or disable_plaintext_auth=yes). I'm looking for the simplest, and don't like redundant/unnecessary settings, so... which is the best/preferred way? And what is the difference between ssl=required and disable_plaintext_auth=yes? Thanks, -- Best regards, */Charles/***

[Dovecot] Problem building dovecot 2.2.10 with pigeonhole 0.4.2

Hi, I am on CentOS 5.10 x86_64 and I am trying to build RPMs for Dovecot 2.2.10 with pigeonhole 0.4.2. I am getting an error that autogen.sh is missing from pigeonhole 0.4.2 source (as available from: http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.2.tar…) /var/tmp/rpm-tmp.89185: line 92: /home/mockbuild/rpmbuild/BUILD/dovecot-2.2.10/dovecot-2.2-pigeonhole-0.4.2/autogen.sh: No such file or directory Indeed, the file is missing, as: tar --list -f dovecot-2.2-pigeonhole-0.4.2.tar.gz | grep autogen ...produces no output. However, I managed to use the latest source code: http://hg.rename-it.nl/dovecot-2.2-pigeonhole/shortlog/32beba3bfd8d which does contain an autogen.sh, and this package worked fine. I guess the released source tar pack should be updated? Thanks and regards, Nick

[Dovecot] Dovecot doesn't seem to read userdb for the first delivery
by phuhimself＠phunehehe.net 02 Jan '14

02 Jan '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hello List, First of all, this is my first post so please bear with me if I miss something. I'm using Postfix with Dovecot 2.0.19 as the LDA. The home directory is of the form `/var/mail/virtual/<domain>/<username>`. The mail directory is under the home directory and named `mail`. `mail_location` is left empty, and userdb is specified using SQL: user_query = SELECT uid AS uid, \ gid AS gid, \ homedir AS home, \ maildir AS mail \ FROM users WHERE email = '%u' Everything had been fine, until I added a new user. In the log, Dovecot complains that it doesn't have permission to create the mail directory (email address replaced): > Jan 2 05:46:19 mail1 dovecot: lda(test(a)test.com): Error: user > test(a)test.com: > Initialization failed: Initializing mail storage from mail_location > setting > failed: mkdir(mail) in directory /var/spool/postfix failed: Permission > denied > (euid=5000(virtual) egid=5000(virtual) missing +w perm: > /var/spool/postfix, > dir owned by 0:0 mode=0755) Sometimes it complains about /run/dovecot instead of /var/spool/postfix, but I think that doesn't really matter. I think not specifying `mail_location` confused Dovecot, as explained in [MailLocation][1]. When I put in the right value for `mail_location` the error went away. What I don't understand is, it is said in the [same document][1] that the userdb field `mail` will override `mail_location` anyway. I would think that I can skip `mail_location` if I specify userdb `mail` for all users. Is the document wrong?

I'm running dovecot version 2.0.9 under CentOS-6.5 . I want to add the following plugin: ==================== require "fileinto"; if header :contains "X-Spam-Flag" "YES" { fileinto "Spam"; } ==================== Could some kind soul tell me where exactly I should place this script (eg "anywhere in /etc/dovecot/dovecot.conf" or "anywhere in /etc/dovecot/conf.d/90-plugin.conf"), and do I need to take any other action? Actually, the folder I should like spam to go to is ~/Maildir/.Spam/cur/ - should I modify the above script? If these queries are anwered clearly in some dovecot documentation, please point me to that. -- Timothy Murphy e-mail: gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin 2, Ireland

[Dovecot] dsync-local crashes due to assertion failures
by Fabian Groffen 30 Dec '13

30 Dec '13

Hi, I have two servers that share nothing, running dovecot version 2.2.9. The first server hosts the original mail base, which I want to sync using dovecot to the second server. With some trial and error I managed to get synchronisation running using tcp sockets. Now for some accounts I see dsync-local crashing on the server that has the original mail base (which is still the only of the two that receives new mail). The log shows: Dec 8 03:13:14 zeus dovecot: dsync-local(someuser): Panic: file mail-index-tr ansaction-export.c: line 203 (log_append_ext_hdr_update): assertion failed: (u32 .offset + u32.size <= ext_hdr_size) Dec 8 03:13:14 zeus dovecot: dsync-local(someuser): Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0(+0x70ea0) [0x7f3ee4137ea0] -> /usr/lib64/dovecot/libdovecot.so.0(+0x70efe) [0x7f3ee4137efe] -> /usr/lib64/dovecot/libdovecot.so.0(i_fatal+0) [0x7f3ee40ebd2c] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mail_index_transaction_export+0xbed) [0x7f3ee442e89d] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0x89104) [0x7f3ee442d104] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mail_index_transaction_commit_full+0xb2) [0x7f3ee442d592] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mail_index_transaction_commit+0xc) [0x7f3ee442d63c] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mail_index_sync_commit+0xb6) [0x7f3ee44372b6] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0x335d6) [0x7f3ee43d75d6] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0x328bc) [0x7f3ee43d68bc] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0x32d83) [0x7f3ee43d6d83] -> /usr/lib64/dovecot/libdovecot-storage.so.0(maildir_storage_sync_init+0xd9) [0x7f3ee43d7199] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mailbox_sync_init+0x2e) [0x7f3ee43e7f2e] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mailbox_sync+0x27) [0x7f3ee43e8047] -> dovecot/doveadm-server(dsync_brain_master_send_mailbox+0xcf) [0x41f17f] -> dovecot/doveadm-server(dsync_brain_run+0x2c8) [0x41d738] -> dovecot/doveadm-server() [0x41dd70] -> dovecot/doveadm-server() [0x42eda0] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_call_io+0x36) [0x7f3ee41495a6] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run+0xbd) [0x7f3ee414a62d] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7f3ee4149008] -> dovecot/doveadm-server() [0x41bb6c] -> dovecot/doveadm-server() [0x40ee3b] -> dovecot/doveadm-server() [0x419581] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_call_io+0x36) [0x7f3ee41495a6] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run+0xbd) [0x7f3ee414a62d] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7f3ee4149008] -> /usr/lib64/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f3ee40f1643] Dec 8 03:13:14 zeus dovecot: dsync-local(someuser): Fatal: master: service(doveadm): child 14116 killed with signal 6 (core dumps disabled) It seems that despite these crashes, some data is being transferred. Newer accounts seem not to have problems, this happens with older accounts only, for as far as I can see. I tried removing the index files, but that didn't seem to help. Any ideas on what I can do here? Both servers are configured to use maildir storage. Thanks, Fabian -- Fabian Groffen Gentoo on a different level

[Dovecot] pop3 rate limit
by Christian Rößner 30 Dec '13

30 Dec '13

Hi, we have customers with Exchange servers that are polling for new mail every minute with dozens of pop3 accounts. I am looking for a mechanism to rate limit this per user. So what I am looking for is a way to block users from polling, if a user asks for new mail more than every 5 minutes (for example). Is this possible? Can this be achieved within Dovecot or does it need external scripting? (I thought about fail2ban, but also want IPv6 support) Thanks in advance -Christian Rößner -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Axel von der Ohe, Marc Schiffbauer Aufsichtsratsvorsitzender: Florian Kirstein

[Dovecot] Sieve's spamtest always returns 0
by martin f krafft 28 Dec '13

28 Dec '13

I am a bit at a loss here with Sieve (pigeonhole) and the spamtest extension. I am using Dovecot 2.1.7 (backported to Debian squeeze), which comes with Pigeonhole 0.3.0. Messages are scanned with SpamAssassin, which adds a header like X-Spam-Status: Yes, score=84.6 required=5.0 tests=… and so I configured spamtest in conf.d/90-plugin.conf like so: sieve_spamtest_status_type = score sieve_spamtest_status_header = X-Spam-Status: [^,]*, score=(-?[[:digit:]]+\.[[:digit:]]).* sieve_spamtest_max_header = X-Spam-Status: [^,]*, score=[^[:space:]]+ required=(-?[[:digit:]]+\.[[:digit:]]).* I tested those regular expressions with sed -r, e.g. % sed -rne "s@^X-Spam-Status: [^,]*, score=-?[[:digit:]]+\.[[:digit:]] required=(-?[[:digit:]]+\.[[:digit:]]).*@\1@p" mailfile 5.0 and they work. Unfortunately, in sieve scripts, the spamtest value is always 0, which is indicative of the spamtest "not having run", which in this case I assume means that the regular expression didn't match. Am I right in assuming that the matching happens at the time of evaluation, and so adding the headers using vnd.dovecot.filter just before works? Or does the spamtest matching happen before the sieve scripts are executed? Can you see any other reason why spamtest always yields a value of 0?

[Dovecot] Dovecot 'Submission' service?

[Dovecot] Using DSync to convert from maildir to m/sdbox during migration of mail to new server
by Charles Marcus 27 Dec '13

27 Dec '13

Ok, now to work out the precise method (config for the target server and dsync command) to use to perform the migration from the old server to the new one, converting to dbox (s or m, depending on how the other thread discussing this turns out). I'll update the old server to 2.2.10 tomorrow morning so they're both at the same version. So, assuming both servers are running 2.2.10, with OldServer: mail_location = maildir:~/:INDEX=MEMORY and NewServer: mail_location = sdbox:~/sdbox or mail_location = mdbox:~/mdbox After reading and re-reading: http://wiki2.dovecot.org/Tools/Dsync I'm not so sure... First problem - apparently it can only be used one user at a time? And - do you have to actually know the users password too? If so, then this probably isn't going to be easier, and maybe even harder than just rsyncing everything, then slowly converting each user one at a time. -- Best regards, */Charles/*

[Dovecot] Migrating from Maildir to dbox+SIS... sdbox or mdbox?
by Charles Marcus 27 Dec '13

27 Dec '13

Ok... Now that I've got the niggling issues resolved, on to bigger and better things. I want to convert everyone from Maildir to dbox and enable SIS (our users use a lot of large attachments), and after some reading/googling, I think it may be better to use dsync instead of rsync for the actual migration after all since it will do this at the same time as the syncing. If I'm not mistaken, once I've figured out the correct syntax for the command, I should be able to do the conversion and migration at the same time. So, that is what I want to do, but I still have to choose between sdbox and mdbox. I tend to feel a little safer with sdbox, just because it seems more stable - and I like the idea that if a file gets corrupted somehow, then it is only that one mail that may potentially be lost, but if mdbox indexes get corrupted, you are guaranteed to lose messages (maybe a lot)... But I also really like the idea of an order of magnitude fewer actual files (would make rsync based backups much faster, etc). Timo - the last comments I was able to find from you were back in 2011... would you mind commenting on the current stated of dbox - especially mdbox, as far as reliability goes? The 'scary warnings' about how important the index files are ... well ... scares me... ;) I know there were definitely some issues with mdbox a few years ago - I found the old thread from 2011, but nothing substantial since, so... So... are there any people here, especially larger installs, using mdbox? sdbox? I'd especially be interested in hearing from anyone who has used both, and picked one over the other, and their reasons for doing so. Thanks, -- Best regards, */Charles/*

[Dovecot] Enabling SIS (single instance storage)
by Charles Marcus 27 Dec '13

27 Dec '13

Ok, didn't find much on this... The bottom of /etc/dovecot/conf.d/10-mail.conf has the following settings: #mail_attachment_dir = #mail_attachment_min_size = 128k #mail_attachment_fs = sis posix #mail_attachment_hash = %{sha1} all of which are apparently the defaults according to doveconf -d output - so no need to set them explicitly, unless I want to change them, right? So, enable the first one - but - the comments don't say anything about supporting variables. I'm assuming you can, otherwise all attachments for all domains would be in a single directory, which some admins might not like (I wouldn't)... so hopefully I can just set it to this: mail_attachment_dir = /var/vmail/%d/.attachments So how does this work during conversion? Users still on maildir simply don't engage it? But as users are converted to dbox, all attachments are de-duped, and then new mails coming in with attachments (for converted users) are de-duped at delivery? The wiki could do with a bit more on enabling and implementing it, especially what to expect when enabling it for the first time on a production system and what to expect along the way when converting existing users... -- Best regards, */Charles/*

[Dovecot] mail_location, user 'home', questions
by Charles Marcus 27 Dec '13

27 Dec '13

Hi all, Ok, another question... I always like changes to the default settings whenever possible (KISS principle)... So, according to the dovecot wiki, the default location for a maildir setup is: mail_location = maildir:~/Maildir However, when I first tried to access mail on the new box, something wasn't right, and I ended up having to change this to: mail_location = maildir:~ to get mail to display correctly. The filesystem for a users maildir currently has everything (cur/new/tmp, and the individual folders) inside that users directory, ie: /var/vmail/example.com/user/ Do I need to change this so that everything is under a 'Maildir' subdirectroy inside the users directory, like: /var/vmail/example.com/user/Maildir/ ? Also, I'm aware that it is important that even virtual users have valid 'homes', but I'm confused as to where these are (or are supposed to be) by default. My sql query currently contains: user_query = \ SELECT CONCAT('/var/vmail/', maildir) AS home \ FROM mailbox WHERE username = '%u' iterate_query = SELECT username AS user FROM mailbox So... what exactly is this saying? That the users 'home' is '/var/vmail'? Or does it automatically append %d/%u? I'm specifically wondering if the intention for the defaults is for the users home to be: /var/vmail/example.com/user and the users maildirs to be in: /var/vmail/example.com/user/Maildir Would appreciate some clarification... It wouldn't be hard to mv all of the users maildirs to a Maildir subfolder after the sync, but I want to know for sure that that is what I should/need to do... Thanks, -- Best regards, */Charles/*

[Dovecot] Thunderbird message cache out of sync after repetitive rsyncs...
by Charles Marcus 27 Dec '13

27 Dec '13

Ok, hopefully there is a solution to this. I've been experimenting with multiple rsyncs in preparation for pulling the trigger on the mail server switch, but have a problem that I really want to fox before doing so. Apparently something causes Thunderbirds local message cache to get out of sync with dovecot after a sync. Here is the series of commands I'm running: 1. stop postfix, stop dovecot on new server 2. rsync -rltgovDHP --delete --exclude-from 'excludes.txt' /path/to/vmail/example.com/ /var/vmail/example.com/ 3. chown vmail:vmail /var/vmail 4. start dovecot, start postfix ls -al /var/vmail/example.com/user/cur shows all of the messages that should be there, and all perms are correct. Go to my account that is pointed to this mail server/account, and none of the new messages show up. Also, some messages are still showing up that shouldn't. I've tried compacting the folders, closing/relaunching Thunderbird, but nothing helps. The only way to get them to show up is to go to the local Thunderbird cache for the account, and delete the files associated with the folder having the problem. The problem is, ALL folders will have this problem, which means that everyone will need to delete ALL of their local cahced folders. This will be a major support problem. Anyone have any ideas? -- Best regards, */Charles/*

[Dovecot] Server Migration Attempt - new messages DELETED after secondary rsyncs
by Charles Marcus 27 Dec '13

27 Dec '13

Starting a new thread, as I've got a lot more details now... First, I know this may be (or is even likely) something weird happening with Thunderbird, but the bottom line is, I have to find a resolution or a workaround or something, or I will be unable to pull the trigger on the server migration. It is simply unacceptable to lose ANY mails doing this. Goal: migrate mailstore from old server to new server using rsync Thunderbird (24.2) is set up to access the new account for testing Problem: after rsync, ls shows new messages (11 for the 27th), but when Thunderbird accesses the maildir again after another rsync, MOST (but not all) of the new messages are deleted (only one for the 27th remains) Timo - I'd be happy to do anything necessary to track this down if you'll just tell me what you need... Note: if you are pretty confident that upgrading dovecot on the old server and using dsync to do the migration will solve the problem, obviously I'm willing to do that if there is no other choice, but... I hope you'll want to get to the bottom of this regardless, as, according to you and everything I've read, it should work without losing any emails... Ok, as to details...

[Dovecot] v2.2.10 released
by Timo Sirainen 27 Dec '13

27 Dec '13

http://dovecot.org/releases/2.2/dovecot-2.2.10.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.10.tar.gz.sig I've been really busy the last few months, as I guess people in Dovecot mailing list have seen since I haven't been very responsive. There are at least some dsync bugs I haven't had time to look into yet. The busyness probably continues for a while more, but the next year is looking much better for me and for Dovecot in general. We're planning to hire a few more Dovecot coders at some point, so if you're interested send me an email. :) + auth: passdb/userdb dict rewrite to support much more complex setups. See doc/example-config/dovecot-dict-auth.conf.ext. The old settings will continue to work. + auth: Added userdb result_success/failure/tempfail and skip settings, similar to passdb's. See http://wiki2.dovecot.org/UserDatabase + imap: Implemented SETQUOTA command for admin user when quota_set is configured. See http://master.wiki2.dovecot.org/Quota/Configuration + quota: Support "*" and "?" wildcards in mailbox names in quota_rules + mysql: Added ssl_verify_server_cert=no|yes parameter. This currently defaults to "no" to make sure nothing breaks, but likely will become "yes" in Dovecot v2.3. + ldap: Added blocking=yes setting to use auth worker processes for ldap lookups. This is a workaround for now to be able to use multiple simultaneous LDAP connections. + pop3c+dsync performance improvements - quota-status: quota_grace was ignored - ldap: Fixed memory leak with auth_bind=yes and without auth_bind_userdn. - imap: Don't send HIGHESTMODSEQ anymore on SELECT/EXAMINE when CONDSTORE/QRESYNC has never before been enabled for the mailbox. - imap: Fixes to handling mailboxes without permanent modseqs. (When [NOMODSEQ] is returned by SELECT, mainly with in-memory indexes.) - imap: Various fixes to METADATA support. - stats plugin: Processes that only temporarily dropped privileges (e.g. indexer-worker) may have been logging errors about not being able to open /proc/self/io.

[Dovecot] obox_fs and Dropbox, someone uses it?

I purchased the license for the Dovecot Object Storage for Dropbox to test this functionality on a personal domain. Unfortunately I can not make it work, I create the token for my Dropbox account from here https://dropbox.dovecot.fi/ and setup in dovecot configuration. When I try to login with an user I found these errors in log file: ============ Dec 27 10:52:16 mail dovecot: imap-login: Login: user=<dovecot1(a)test.it>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=8844, secured, session=<xxCXDIHuTQB/AAAB> Dec 27 10:52:16 mail dovecot: metacache-worker(8839): Error: fs-dropbox: GET 1/metadata/sandbox/dovecot1(a)test.it/idx/?file_limit=25000 failed: 401 Unauthorized Dec 27 10:52:16 archiviomail dovecot: metacache-worker(8839): Error: Failed to iterate dovecot1(a)test.it/idx/: GET 1/metadata/sandbox/dovecot1(a)test.it/idx/?file_limit=25000 failed: 401 Unauthorized Dec 27 10:52:16 mail dovecot: imap(dovecot1(a)test.it): Error: user dovecot1(a)test.it: Initialization failed: Namespace '': obox: USER-REF: /var/run/dovecot/metacache returned failure Dec 27 10:52:16 mail dovecot: imap(dovecot1(a)test.it): Error: Invalid user settings.

[Dovecot] German Umlauts in folder name and sieve

[Dovecot] Question re: indexes

26 Dec '13

Hi all, On the old/current dovecot server, I have disabled on disk indexes: mail_location = maildir:~/:INDEX=MEMORY On the new server, I removed the 'INDEX=MEMORY' part, and I now see some new index related files, but what I don't see is the main dovecot.index file... I only have: dovecot.index.cache and dovecot.index.log So... where is the main dovecot.index file? -- Best regards, */Charles/*

I have dovecot version 2.2.9 on Linux 3.11.0-14-generic x86_64 Ubuntu 13.10 and I get the same results on 32-bit Debian as well. Does anyone have idea what's wrong? Thanks in advance, Jouko Nikula

[Dovecot] Patch for Dovecot's quota policy daemon
by Peer Heinlein 24 Dec '13

24 Dec '13

Hi Timo, we wrote a simple Patch for the Dovecot quota policy daemon. If a user is over quota, I prefer blocking the user sending e-mails, so I need a policy daemon, that's able to use the envelope or sasl sender as lookup key. I'd be happy if that patch can become part of the normale Dovecot releases. Peer -------- Original-Nachricht -------- Betreff: Re: Fwd: Quota-Patch Datum: Wed, 11 Dec 2013 17:33:45 +0100 Von: Stephan Seitz <s.seitz(a)heinlein-support.de> Organisation: Heinlein Support GmbH An: Peer Heinlein <p.heinlein(a)heinlein-support.de> Parameter r Code ENUM QUOTA_MATCH_RECIPIENT Stringmatch recipient= ${recipient} This macro expands to the complete recipient address.

[Dovecot] Eliminate legacy INBOX namespace - how?
by Charles Marcus 23 Dec '13

23 Dec '13

Hi all, Our mailstore was converted from a Courier-IMAP system last year, but I am planning a migration to a shiny new VM, and would really like to clean things up and do away with the legacy INBOX namespace. My goal is to simplify IMAP client setup - no special 'INBOX' namespace needed, they just enter the server info and credentials. Also important because I will be rolling out SOGo, which has a nice web interface, and I want the mailstore to be as close to default dovecot settings as possible - although I do plan on converting from maildir to mdbox when I do the conversion I also don't want other folders to show up as subfolders of the Inbox in IMAP clients, they should all show up on the same level as the Inbox. I've read http://wiki2.dovecot.org/Migration/Courier, but I don't see anything about how to eliminate this stupid legacy INBOX. namespace, so that new IMAP clients won't show all folders as subfolders of the INBOX unless/until they add the INBOX namespace prefix in the advanced settings. I've also been reading http://wiki2.dovecot.org/Namespaces, but I'm still confused as to how to go about this. Currently I have: namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = INBOX. separator = . } The wiki recommends avoiding the 'alternative' of having two different namespaces, so I don't want to do that. Also - it would be ok if existing clients had temporary issues displaying folders properly until the INBOX prefix was removed (I would give everyone plenty of advance warning). Anyone ever done this before? Any suggestions Timo? Note: I am planning a migration to a new mail server (VM), so could make any filesystem layout changes when I do this if necessary. Thanks, -- Best regards, */Charles/*

[Dovecot] Is the users password available from a mail_filter?
by martijn.list 23 Dec '13

23 Dec '13

Hi, I'm working on a Dovecot encryption module which uses the mail filter plugin to encrypt/decrypt the message "on the fly". I was wondering whether it is possible to access the password (or a hashed password) of the user. It seems that only the user (using the %u parameter) is available to the mail_filter plugin. Any idea how to get hold of the (possibly hashed) password? Kind regards, Martijn Brinkers

Hi I have strange situation with one of mailboxes in mdbox format. Some messages are duplicated, not all. I am sure that is not sieve or another mail client issue, because access is via roundcube without sieve plugin.

[Dovecot] Horde + dovecot metadata support
by Andreas Schulze 23 Dec '13

23 Dec '13

Hello, Horde (http://horde.org) has the ability to store its preferences direct into a users imap mailbox using imap metadata extension. There are two implementations of the imap extension. 1. a dovecot plugin: http://hg.dovecot.org/dovecot-metadata-plugin 2. dovecot itself: http://www.dovecot.org/list/dovecot/2013-November/093243.html I setup Horde and dovecot-2.2.5 to use this extension and it works well using 1.) Now, with dovecot-2.2.9, the plugin fail to compile (unrelated problem on my side). So I tried 2.) But here I get a Horde-Error "Error in IMAP command GETMETADATA: Invalid arguments." I enables mail_debug but saw no helpfull logging. mail_attribute_dict = file:/tmp/%Lu/dovecot-attributes remote horde.testserver.ip/32 { imap_metadata = yes mail_debug = yes } Also I created directory /tmp/$my_login_id (mode 777) but dovecot also created no files. neither it logs anything about it. This is a sample imap session generated by horde: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN AUTH=LOGIN] Dovecot ready. 1 AUTHENTICATE PLAIN *** 1 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS THREAD=ORDEREDSUBJECT MULTIAPPEND URL-PARTIAL CATENATE UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS SPECIAL-USE BINARY MOVE METADATA QUOTA] Logged in 2 NAMESPACE * NAMESPACE (("" "."))

Are there any hints or is the metadata extension just not fully implemented in dovecot?

[Dovecot] TLS SNI with Dovecot
by Michael Neurohr 22 Dec '13

Hi! I've been using Dovecot for one single Domain with SSL certificates. Now I would like to use Dovecot with several Domains and proper SSL certificates. I tried to setup TLS SNI but it does not work.

When trying to login via IMAP, I see the following lines in the log file: =================================================================== Dec 22 21:01:05 mx0 dovecot: imap-login: Warning: SSL alert: where=0x4004, ret=554: fatal bad certificate [151.236.5.22] Dec 22 21:01:05 mx0 dovecot: imap-login: Warning: SSL failed: where=0x2002: SSLv3 read client certificate A [151.236.5.22] Dec 22 21:01:05 mx0 dovecot: imap-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=151.236.5.22, lip=151.38.7.25, TLS handshaking: SSL_accept() failed: error:14094412:SSL routines:SSL3_READ_BYTES:sslv3 alert bad certificate: SSL alert number 42, session=<Rg5EzyXutgCX7AaF> =================================================================== The actual Dovecot config is pasted below.

[Dovecot] Duplicated (but only for unread) messages after second rsync pass...
by Charles Marcus 22 Dec '13

22 Dec '13

Ok, I know I should probably be using dsync for this, but I'm more familiar with rsync, and didn't think this would be a problem. Here is what I am doing, and what is apparently happening (only done this once, but I'm guessing it will happen each time): rsync -avHP /mnt/vmail/example.com/user1/ /var/vmail/example.com/user1/ chown -R vmail:vmail /var/vmail/example.com Ok, so far so good, everything works fine accessing the mails (I'm using Thunderbird). Now I do another rsync, but this time I did the entire mailstore: rsync -avHP /mnt/vmail/example.com/ /var/vmail/example.com/ chown -R vmail:vmail /var/vmail/example.com Right after I started up dovecot again, I hot a bunch of these in the logs: 2013-12-22T09:52:51-05:00 newhost dovecot: imap(user1(a)example.com): Warning: Maildir /var/vmail/example.com/user1/: Expunged message reappeared, giving a new UID (old uid=45516, file=1387468268.Vfe02Ic1343fM845754.oldhost.sub.example.com:2,ST) 2013-12-22T09:52:51-05:00 newhost dovecot: imap(user1(a)example.com): Warning: Maildir /var/vmail/example.com/user1/: Expunged message reappeared, giving a new UID (old uid=45518, file=1387468645.Vfe02Ic73e0eM530539.oldhost.sub.example.com:2,ST) The problem is, it looks like every single message that was flagged as unread is now duplicated on the new system. Also - not that this is a problem, but all of the old messages have the fqdn of the old server in the individual email file names - oldhost.sub.example.com - while the new ones only have the local hostname (newhost) Did I do something wrong? Or is this going to be an unavoidable problem if I want to use rsync to do the final migration that using dsync would avoid? Thanks, -- Best regards, */Charles /*

[Dovecot] Dovecot proxying with LDAP - an example?
by Graham Leggett 22 Dec '13

22 Dec '13

Hi all, I have been struggling trying to understand the syntax to configure dovecot as a proxy against an LDAP server. As a single server dovecot works great. Now I want to add the "mailHost" attribute which, if present, should indicate the DNS name of the host that contains the person's mailbox. If the mailHost matches the local hostname, the mailbox should be served locally as it already does now. If the mailHost is not the local hostname, dovecot should proxy the request to the given server using SSL on port 993. The docs at http://wiki2.dovecot.org/PasswordDatabase/ExtraFields/Proxy suggest that proxy_always is what I am looking for, but I cannot find any worked examples of how this might work. Has anyone attempted this before? What I have so far is this, but no proxying seems to take place: pass_attrs = mail=user,userPassword=password,\ mailMessageStore=userdb_mail,=proxy_always=y,mailHost=host,=ssl=yes Can anyone confirm? I am using dovecot v2.0.9 as provided out the box by RHEL6. Regards, Graham --

[Dovecot] 'unknown user' using dovecot LDA
by Charles Marcus 22 Dec '13

22 Dec '13

Ok, one more issue to resolve. The old server was still using the postfix/virtual for delivery, but the new one is using the dovecot LDA. Now, when an email generated locally by a cron job is delivered, this shows in the log: 2013-12-22T10:29:55-05:00 host postfix/pickup[31400]: C67FD90F676B2: uid=0 from=<newsrv+rkhunter(a)example.com> 2013-12-22T10:29:55-05:00 host postfix/cleanup[22349]: C67FD90F676B2: message-id=<20131222152955.C67FD90F676B2(a)smtp2.example.com> 2013-12-22T10:29:55-05:00 host postfix/qmgr[31401]: C67FD90F676B2: from=<newsrv+rkhunter(a)example.com>, size=1555, nrcpt=1 (queue active) 2013-12-22T10:29:55-05:00 host dovecot: auth-worker(22365): passwd(user1(a)example.com): unknown user 2013-12-22T10:29:55-05:00 host dovecot: lda(user1(a)example.com): msgid=<20131222152955.C67FD90F676B2(a)smtp2.example.com>: saved mail to INBOX 2013-12-22T10:29:55-05:00 host postfix/pipe[22361]: C67FD90F676B2: to=<user1+rkhunter-report(a)example.com>, relay=dovecot, delay=0.06, delays=0.02/0/0/0.04, dsn=2.0.0, status=sent (delivered via dovecot service) 2013-12-22T10:29:55-05:00 host postfix/qmgr[31401]: C67FD90F676B2: removed The mail was delivered (as the log also clearly shows), but what is with the 'unknown user'? I'm not sure how I can test my maps with dovecot, but testing with postfix shows: # postmap -q user1(a)example.com mysql:/etc/postfix/maps/mysql/vmm.cf example.com/user1/ Which is correct. And my dovecot-sql-conf.ext contains: driver = mysql connect = "host=localhost dbname=db_name user=dbuser password=password" default_pass_scheme = CRYPT password_query = \ SELECT username AS user, password \ FROM mailbox WHERE username = '%u' user_query = \ SELECT CONCAT('/var/vmail/', maildir) AS home \ FROM mailbox WHERE username = '%u' iterate_query = SELECT username AS user FROM mailbox I confirmed the db info is identical to what postfix is using. Oh - and in order to make sure that all usernames are lowercased, shouldn't I change '%u' above to '%Lu'? Appreciate any suggestions on where to go next... thanks -- Best regards, */Charles/*

Hi all, Ok, I'm making progress on my new server, but there is an entry in the logs on the old/current server that is not showing p on the new one... lines like: dovecot: auth-worker(20284): mysql(localhost): Connected to database my_auth_db I've looked everywhere, compared settings, etc, and can't seem to find why I get this line on the old server and odn't on the new one. Anyone have a clue stick? Thanks

[Dovecot] File descriptor leak in sieve-extprograms

[Dovecot] Ignoring mount points for secondary dovecot instance does not seem to work
by Jouko Nikula 21 Dec '13

21 Dec '13

Hello, I tried to ignore all mountpoints in Dovecot. I have two dovecot instances running: root@fileserver# doveadm instance list path name last used running /usr/local/var/run/dovecot dovecot 2013-12-21 08:09:34 yes /var/run/dovecot.smtp smtp-auth 2013-12-21 08:09:34 yes I give commands: root@fileserver# doveadm mount add '/*' ignore root@fileserver# doveadm -i smtp-auth mount add '/*' ignore And then restart dovecot. In the log I can see that the main instance is now ignoring my mountpoints, but the smtp-auth instance is still warning about my mountpoints. Is this a bug or am I missing something? My configurations are as follows: root@fileserver# doveconf -ni smtp-auth # 2.2.9: /usr/local/etc/dovecot/dovecot.conf.smtp # OS: Linux 3.2.0-4-686-pae i686 Debian 7.1 auth_mechanisms = plain login base_dir = /var/run/dovecot.smtp/ first_valid_uid = 123 instance_name = smtp-auth log_timestamp = "%Y-%m-%d %H:%M:%S " mail_gid = mail mail_location = maildir:~/mail mail_uid = vmail passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } passdb { args = dovecot driver = pam } protocols = service auth-worker { user = vmail } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } ssl_cert = </etc/ssl/certs/imapd.pem ssl_key = </etc/ssl/private/imapd.pem userdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } root@fileserver# doveconf -n # 2.2.9: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-686-pae i686 Debian 7.1 auth_mechanisms = plain login first_valid_uid = 123 log_timestamp = "%Y-%m-%d %H:%M:%S " mail_gid = mail mail_location = maildir:~/mail mail_uid = vmail passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } passdb { args = session=yes dovecot driver = pam } protocols = imap service auth-worker { user = vmail } ssl_cert = </etc/ssl/certs/imapd.pem ssl_key = </etc/ssl/private/imapd.pem userdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } regards, - Jouko

Hi all, I've been on this list for 18 months but almost completely as a lurker. You know why? Because Dovecot never, ever, ever screws up on me or displays unexpected behavior, so I never have technical questions. Thank you for producing such a rock solid piece of software!

Re: [Dovecot] configure lmtp to deliver to email addresses case insensitively
by Adrian Zaugg 20 Dec '13

20 Dec '13

Hi David > I believe RFC822 email addresses are case-insensitive, and (in some RFC 2821, Page 13, 1st paragraph: "The local-part of a mailbox MUST BE treated as case sensitive. Therefore, SMTP implementations MUST take care to preserve the case of mailbox local-parts. Mailbox domains are not case sensitive. In particular, for some hosts the user "smith" is different from the user "Smith". However, exploiting the case sensitivity of mailbox local-parts impedes interoperability and is discouraged." (http://tools.ietf.org/html/rfc2821#section-2.4) > cases, especially ones where there's just a mail server) it's entirely > possible that people remember their account names with some capital > letters that aren't in user db. (System knows you as > "mrsmithy(a)mail.domain", while the user may remember the account as > "MrSmithy(a)mail.domain" or "MrsMithy(a)mail.domain"...). Also, people with I just want login names to be case sensitive but not email addresses, and in spite of being treated as case insensitive email addresses should retain their case, just like defined and suggested in the RFC. This reduces support calls because it's con-formant and we have a clear policy: Usernames are always lower case, non-email addresses, the same simple and short name for all our services. There is nothing easier than this. We use this since 17 years and it works without confusion. If a user now spots that suddendly any capitalization of usernames is working when logging in to the webmail, how can I explain that this doesn't work with other services like FTP? > smartphones may not notice that the phone "helpfully" uppercased the > first letter of a lowercase user name. Forcing case reduces support > calls, which is always a good thing. That's why email addresses should be allowed containing capitalizations. On smartphone people tend to use MUAs and there the username is saved and not entered each and every time, so for the username this is less true, I think. Back to dovecot: Using LDA as a transport for the dovecot store, it used to work perfectly (with dovecot 1.x). It's just LMTP that spits, because it looks up the local part in the userdb, which is PAM in our case. I won't change PAM to act case insensitive: I'm not in the position to change a common sense in the computing world as it always was. It's enough Microsoft did that and probably just because of that we're having this discussion here... However, it's maybe best to lowercase the local part in the exim lmtp-transport and leave dovecot's LMTP in peace. Best regards, Adrian.

[Dovecot] Does quota-status respect quota_grace?
by Jiri Bourek 20 Dec '13

20 Dec '13

Hello, I have Dovecot 2.2.9 from Debian repository running on AMD64, ext4 filesystem for mail storage. Each mailbox has its own system user, quotas are enforced by file system. Quota settings in configuration are as follows (from doveconf -n): quota = fs:Domain quota:group:inode_per_mail quota2 = fs:Mailbox quota:user:inode_per_mail quota2_grace = 18%% quota_grace = 18%% quota_status_nouser = DUNNO quota_status_overquota = 552 5.2.2 Mailbox is full quota_status_success = DUNNO Quota rules are read from PostgreSQL (snippet) user_query = ... '*:bytes=' || domains.quota_size || 'M:messages=' || domains.quota_files as quota_rule, \ '*:bytes=' || mailboxes.quota_size || 'M:messages=' || mailboxes.quota_files as quota2_rule, \ ... As far as I can tell, quota enforcing in dovecot-lda works correctly. User is allowed one message which brings him over quota (provided the message fits into filesystem quota hard limit and quota_grace value), every other message after that is rejected. However policy service quota-status for Postfix seems to ignore the quota_grace value. When a message arrives which would make user go over quota (but which would not make him exceed the grace limit value), Postfix checks the policy service and is told to reject the message. I checked and dovecot itself is fine with the message - if I try to send it with the policy service check disabled, Postfix accepts it and so does dovecot-lda, the message is delivered into mailbox. My question is - is that intended behavior or bug in the quota-status? Appending some lines from debug log - as far as I can see there's not much in it though: dovecot: quota-status: Debug: Added userdb setting: mail=maildir:/home/mailboxes/t/e/test.info/test/:LAYOUT=fs:INDEX=/var/lib/dovecot-data/index/1010:CONTROL=/var/lib/dovecot-data/control/1010 dovecot: quota-status: Debug: Added userdb setting: plugin/quota2_rule=*:bytes=11M:messages=110 dovecot: quota-status: Debug: Added userdb setting: plugin/quota_rule=*:bytes=15M:messages=150 dovecot: quota-status(test(a)test.info): Debug: Effective uid=1010, gid=1007, home=/home/mailboxes/t/e/test.info/test/ dovecot: quota-status(test(a)test.info): Debug: Quota root: name=Domain quota backend=fs args=group:inode_per_mail dovecot: quota-status(test(a)test.info): Debug: Quota rule: root=Domain quota mailbox=* bytes=15728640 messages=150 dovecot: quota-status(test(a)test.info): Debug: Quota grace: root=Domain quota bytes=2831155 (18%) dovecot: quota-status(test(a)test.info): Debug: Quota root: name=Mailbox quota backend=fs args=user:inode_per_mail dovecot: quota-status(test(a)test.info): Debug: Quota rule: root=Mailbox quota mailbox=* bytes=11534336 messages=110 dovecot: quota-status(test(a)test.info): Debug: Quota grace: root=Mailbox quota bytes=2076180 (18%) dovecot: quota-status(test(a)test.info): Debug: Namespace inbox: type=private, prefix=, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:/home/mailboxes/t/e/test.info/test/:LAYOUT=fs:INDEX=/var/lib/dovecot-data/index/1010:CONTROL=/var/lib/dovecot-data/control/1010 dovecot: quota-status(test(a)test.info): Debug: fs: root=/home/mailboxes/t/e/test.info/test, index=/var/lib/dovecot-data/index/1010, indexpvt=, control=/var/lib/dovecot-data/control/1010, inbox=/home/mailboxes/t/e/test.info/test, alt= dovecot: quota-status(test(a)test.info): Debug: fs quota add mailbox dir = /home/mailboxes/t/e/test.info/test dovecot: quota-status(test(a)test.info): Debug: fs quota block device = /dev/sdc1 dovecot: quota-status(test(a)test.info): Debug: fs quota mount point = /home dovecot: quota-status(test(a)test.info): Debug: fs quota mount type = ext4

[Dovecot] auth failures

Hello, last week and today our dovecot pop3 server stopped responding. Without any other logentries dovecot start to log only this: Dec 12 09:14:12 mbox1 dovecot: auth: Error: ldap(testuser,192.0.2.110,<FBZH7lHtAQAK/FCj>): ldap_search(base=ou=accounts,dc=example,dc=de filter=(&(|(uid=testuser)(mail=testuser))(!(state=blocked)))) failed: Operations error For every pop3 Session, ~2000 per Minute ..., over 10 Minutes I send dovecot a SIGTERM. After dovecot was started again, all was fine again. # doveconf -n http://postmaster.datev.de/tmp/dovecot.conf The LDAP-Server itself did resond to queries in the same timeframe. I know this because the MTA on the same host was able to deliver messages into mailboxes. Any hints?

[Dovecot] External auth

Hello, I saw a lot of tutorials about setting postfix with dovecot sasl but I would like more. I want to set a SSO system with roundcube on dovecot. I would like to know how to make dovecot work with sasl or saml, not as a provider but as a service plugging on an external provider. I saw there is an EXTERNAL auth mechanism but I didn't find any doc about it. Can you help me ? Thanks.

[Dovecot] Mailbox with .broken files

We're using Dovecot 2.2.4 and mdbox storage with compression. I noticed yesterday that at least one of the accounts has unusual files in it's mail/storage directory.

Starting on Dec 11, storage files m.409 through m.731 have not only their m.### file, but also a m.###.broken file.

[Dovecot] problem with password in a changing scenario
by Angel Luis Mateo Martinez 19 Dec '13

19 Dec '13

Hello, I'm having a problem with with password changing. According to http://wiki2.dovecot.org/Authentication/Caching, I understand "normal scenario" and "Using old cached password scenario", but I'm having a problem with the "Early change scenario". I understand that in this case, if in step 4 user tries password Y, then this password is not tried again and login fails. But if the user tries another password Z, then is it test it? Or does it directly fail? I think that it is directly failing. And here is my problem... I am using dovecot with a ldap backend and another pam backend. The first one is users connecting with an email client. The other one applies when the ldap backend fails and it is use for connections from our webmail, which is integrated in our CAS SSO environment (it has running an imap proxy too). Sometimes (the only scenari we were able to reproduce is with users that for some reason has two SSO sessions opened) dovecot receives an invalid CAS ticket, then authentication fails, and no newer tickets are tried until cache is clean. That's why I think that in this scenario another Z password is even tried. Any idea? -- Angel L.

[Dovecot] letters local filter duplicated
by John Smith 18 Dec '13

18 Dec '13

two servers with replicated master/master. dovecot.conf = http://pastebin.com/jVnvyWZM with this setup letters processed local filter duplicated. ie when the mail client receives a letter begins processing using rules (filters) to move the letters in a different folder. summarized in this folder is two duplicate letters. if you disable the filter, the message is not duplicated. But does not move to another location. -- Best Regards, Evgeny Senior System Administrator OOO "Vaz Service Hurley"

[Dovecot] Size detection/replair does not work with zlib
by Roland Rosenfeld 18 Dec '13

18 Dec '13

Hi! Usually dovecot auto detects or repairs the size of a maildir message. So I can place a message named "foo" in the cur directory and dovecot uses it. Now I tried the same with a zlib compressed message but here dovecot doesn't recognize/repair the size of the message. When I access this folder via IMAP the connection is diconnected and in dovecot logs I see the following error messages: Error: Cached message size smaller than expected (805 < 2666) Error: Corrupted index cache file /somedir/dovecot.index.cache: Broken physical size for mail UID 23 Error: read() failed: Input/output error (FETCH for mailbox INBOX UID 23) Disconnected: Internal error occurred. Refer to server log for more information. [2013-12-12 10:54:18] in=321 out=1977 As you can see in the first line, dovecot does know the compressed size of the file (805) as well as the uncompressed size (2666), but it isn't able to repair its index for this. If I modify the setup a little with a standard file naming but with a wrong file size in S-flag (compressed size instead of uncompressed size), the log entries become stranger: Error: Cached message size smaller than expected (805 < 2666) Error: Maildir filename has wrong S value, renamed the file from /somedir/cur/1386772057.M152553P9709.host,S=805:2, to /somedir/cur/1386772057.M152553P9709.host,S=805:2, So here dovecot detects the wrong S value, but instead of fixing it by using the uncompressed size, it renames to the same file name as before... All the above was tested with dovecot 2.1.17. We did a short cross test with 2.2.9 which gives somewhat different error messages, but also isn't able to detect/repair the (uncompressed) file size: Error: Cached message size smaller than expected (805 < 2666) Error: Corrupted index cache file /somedir/dovecot.index.cache: Broken physical size for mail UID 23 Error: read(zlib(/somedir/cur/foo)) failed: Invalid argument We also noticed that on both dovecot versions after trying to access the above file, dovecot.index.cache is always deleted and not rebuild... Is all this intended behavior? It sounds different to the standard behavior of dovecot, that repairs broken folders if possible... Ciao Roland

[Dovecot] configure lmtp to deliver to email addresses case insensitively
by Adrian Zaugg 17 Dec '13

17 Dec '13

Dear List Using dovecot 2.1.7 with LMTP and exim4 I want to accept local parts regardless of their case. Exim does all virtual alias handling and delivers the messages to dovecot LMTP addressed to the right mailbox name. This works well except for addresses which do not need to be resolved by exim and which do have the "wrong" case in the local part. For example: There is a mailbox and a user on the mailsystem "example.org" called "user". Mails to "user(a)example.org" get delivered just as they should. If an incoming message is addressed to "USER(a)example.org" with upper case local part, exim passes the message to LMTP with the case unaltered (RFC 2821 conform), but LMTP fails with: LMTP error after RCPT TO:<USER(a)example.org>: 550 5.1.1 <USER(a)example.org> User doesn't exist: USER(a)example.org How can I tell dovecot to deliver "USER" to the mailbox "user" aswell? Thank you for your help. Best regards, Adrian. (I have tried to use %Ln and %Lu in mail_location setting with no success.)

[Dovecot] Dovecot proxy and Postfix SASL
by Andreas Kasenides 17 Dec '13

17 Dec '13

Can somebody please verify that currently (v 2.2.9) SMTP AUTH using SASL from Postfix with Dovecot proxy is still not supported as discussed in these threads (especially the first one)? http://www.dovecot.org/list/dovecot/2012-August/067977.html http://www.dovecot.org/list/dovecot/2011-May/059107.html As I understand it is possible to use saslauthd to do this by using the remote imap option (rimap). Such a facility is important since I am attempting to separate the outward facing servers (dovecot proxy, postfix relay) that have no knowledge of user databases from the backends. thanx Andreas

[Dovecot] Accessing plain text password from memory
by Stanislas SABATIER 17 Dec '13

17 Dec '13

Is there a way to retrieve the client's password in plain text from memory ? I don't store the password in plain text in my postgreSQL but I need it when the client is connected to make crypto computation. If I write a plugin to do the job, how could I retrieve the plain text password from master ? Thank you for your help, Regards, Stan. --------------------------------------------------------------- Stanislas SABATIER s.sabatier(a)pobox.com ---------------------------------------------------------------

[Dovecot] Turn of mount point adding?
by Scott Galambos 16 Dec '13

16 Dec '13

I'm running dovecot 2.2.5 and would like to completely turn off all automatic adding of mount points. So var/lib/dovecot/mounts would be empty essentially. Is this possible? Somehow dovecot always adds a mount point that does not exist and was removed a long time ago. I've dove: doveadm mount add '/my custom path/*' ignore but it still will add mount points in the "mounts" file and flag them as online. for example: ignore /apps/proftp/servers/ftp.domain.ca/* ignore /mnt/* online / online /apps/proftp/servers/ftp.domain.ca/www.site1.com online /apps/proftp/servers/ftp.domain.ca/www.site2.com online /apps/proftp/servers/ftp.domain.ca/www.site3.com what does it list site1, 2 and 3 if its suppose to ignore the root path with the first line? I would to completely disable all mountpoints. Even "doveadm mount add '/*' ignore" should render a mounts file empty on reboot correct? It doesn't and keeps rebuilding it.

[Dovecot] Is mail deleted when mail-filter fails?
by martijn.list 15 Dec '13

15 Dec '13

Hi, While experimenting with the mail-filter, during some tests my filter failed with a non-zero exit code and did not write any data to the output. This seems to result in a lost email. Is this correct? Is there a way to gracefully handle error from a mail-filter out script? Kind regards, Martijn Brinkers

[Dovecot] Possible pigeonhole dealing with negative numerical values
by Sam Mulvey 14 Dec '13

14 Dec '13

Using dovecot 2.2.9 and pigeonhole 0.4.2 The system is a Xen VM running Arch Linux x86_64, presently up to date, on an XFS filesystem in an LVM2 partition. After recently updating my mail server, I found that a sieve rule I had which would check X-Spam-Score for a value over a certain number, in my case 2.5. In my most recent update, negative values would trip the rule. Here's the rule in question: # rule:[Spam Filter Subject] if anyof (header :contains "Subject" "[SPAM]", header :value "gt" :comparator "i;as cii-numeric" "X-Spam-Score" "2.5") { fileinto "Spam Box"; stop; } I have a successful work-around by checking the numerical value and also insuring that the header doesn't contain a '-', and things work as they should. Possible the bug could be in my Sieve interface, which is a RoundCube plugin. Otherwise things are working great. If there's anything I can add, please let me know. Thanks! -Sam dovecot -n output: # 2.2.9: /etc/dovecot/dovecot.conf # OS: Linux 3.12.4-1-ARCH x86_64 xfs auth_cache_size = 512 k auth_cache_ttl = 10 mins auth_mechanisms = plain login auth_verbose = yes default_internal_user = mailstore first_valid_gid = 50 first_valid_uid = 50 hostname = tacomatelematics.com last_valid_gid = 50 last_valid_uid = 50 lda_mailbox_autocreate = yes mail_gid = 50 mail_location = maildir:/var/spool/mail/%d/%n/Maildir/ mail_privileged_group = postfix mail_uid = 50 managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave namespace { inbox = yes location = prefix = separator = . type = private } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } postmaster_address = postmaster(a)tacomatelematics.com protocols = imap pop3 lmtp sieve service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-master { group = mailstore mode = 01130 user = mailstore } unix_listener auth-userdb { group = mailstore mode = 0600 user = mailstore } } service managesieve-login { inet_listener sieve { port = 4190 } inet_listener sieve_deprecated { port = 2000 } } ssl_cert = </etc/certificate.pem ssl_key = </etc/certificate.pem userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol lmtp { mail_plugins = " sieve" } protocol lda { mail_plugins = " sieve" }

[Dovecot] v2.2.8 released
by Timo Sirainen 13 Dec '13

13 Dec '13

http://dovecot.org/releases/2.2/dovecot-2.2.8.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.8.tar.gz.sig + Mail cache lookups work for the mail being saved. This improves performance by avoiding the need to parse the mail multiple times when using some plugins (e.g. mail_log). + Mail cache works for recently cached data also with in-memory indexes. + imapc: Many performance improvements, especially when working with dsync. Also added imapc_feature=fetch-headers which allows using FETCH BODY.PEEK[HEADER.FIELDS (..)] to avoid reading the entire header. + mail_location = ..:FULLDIRNAME=dbox-Mails is the same as :DIRNAME=dbox-Mails, but it will also be used for :INDEX and :CONTROL directories. (It should have worked this way from the beginning, but can't be changed anymore without breaking existing installations). - Fixed infinite loop in message parsing if message ends with "--boundary" and CR (without LF). Messages saved via SMTP/LMTP can't trigger this, because messages must end with an "LF.". A user could trigger this for him/herself though. - lmtp: Client was sometimes disconnected before all the output was sent to it. - imap_zlib plugin caused crashes during client disconnection in v2.2.7 - replicator: Database wasn't being exported to disk every 15 minutes as it should have. Instead it was being imported, causing "doveadm replicator remove" commands to not work very well.

I googled "safe_mkstemp permission denied" and first hit is this thread dovecot.org/list/dovecot/2010-August/052319.html which mentions this error coming about from chrooting users. Looking back on your post, I see http://www.dovecot.org/list/dovecot/2013-December/093900.html mail_chroot = /var/vmail As long as your desperate, maybe try leaving this setting empty?

[Dovecot] dovecot-imapd eating 100% cpu every once in a while

Hello, About once or twice a week, dovecot's imap-login process on my system seems gets out of control, eating 100% CPU for about 2 hours. Afterwards everything seems to go back to normal.

[Dovecot] Locking down master user to certain domains through passwd-file auth
by Andrew Obertas 12 Dec '13

12 Dec '13

Hello, I know it is possible to lock down a master user to only have access to certain domains through SQL login but I was wondering if the same was possible with a passwd-based system. I currently have a master-passwd file residing in the /etc/virtual/domain.com/ directories I want the master user to be able to log in to. Is there a way to tell passdb to only allow the master user login to proceed if they can auth to the master-passwd file in the same folder as the user? Alternatively, is there a better way to go about this? What I assumed would be the easy approach, where the domain from the user's e-mail is fetched, doesn't seem to work as %d fetches the master user's domain and, unless I'm doing something wrong, the login_domain variable cannot be used as this is outside Dovecot-auth. Any assistance with this would be appreciated. -- Best regards, Andrew Obertas Technical Support Representative Infinet Communications Group

[Dovecot] what's wrong with this config file?
by Jim Reid 12 Dec '13

12 Dec '13

Hi. I'm setting up a new IMAPS server. Mail users don't have login access to the box but will each have unique UNIX-style UIDs: no back-end database or LDAP thing. So far. Their mail will get delivered to UNIX-style mailboxes in /var/mail/%u (where %u is the UNIX username obviously). Their IMAP folders will go in /var/imap/%u. These will contain subfolders once everyone migrates to the new set-up and some folders will contain messages and subfolders. I think this is what I configured in dovecot. However when I try to set up a test account, dovecot reports the following error: Dec 12 02:22:00 shaun dovecot: imap-login: Login: user=<jim>, method=CRAM-MD5, rip=10.0.0.1, lip=10.1.1.1, mpid=14874, TLS, session=<8Hy1Ak3t+gDDNulD> Dec 12 02:22:00 shaun dovecot: imap(jim): Error: user jim: Initialization failed: namespace configuration error: Duplicate namespace prefix: "" Dec 12 02:22:00 shaun dovecot: imap(jim): Error: Invalid user settings. Refer to server log for more information. I've checked and re-checked the wiki. google was unable to suggest any explanation either. Any ideas what's wrong?

[Dovecot] ot: tracking messages- luser troubleshooting

I had a user complaining of 'not getting emails' I've searched for sender in maillog, got two messages, both showed up as; Dec 12 15:51:29 emu postfix/pipe[9607]: 3F21C5E750: to=<xxx>, relay=dovecot, delay=6.4, delays=6.3/0.01/0/0.12, dsn=2.0.0, status=sent (delivered via dovecot service) Dec 12 15:51:29 emu postfix/qmgr[20178]: 3F21C5E750: removed yes the user claimed the message was not received, eventually, after traversing through severl directories, I found the message in '../Maildir/.Deleted Messages' it turns out it was inadvertenltly deleted on iphone. there has to be a better way to try to find / resolve such issues ? what's an optimal way of trying to trace such? I greped for the 3F21C5E750 string through several Maildirs tia,

[Dovecot] Dovecot as caching proxy
by Anton Lundin 12 Dec '13

12 Dec '13

Hi. I'm bin playing around with dovecot to try to setup it as a caching imap proxy. I manged to get dovecot to use both proxy=y and imapc: connections to the master server, but i haven't manged to get dovecot to cache any mails. The remote imap server is a quite hostile one, that i don't have any super/master user access to, and it only exposes imap. I've used tried both with the static passdb, nopassword=y, and imap authdb and with static and prefetch userdbs. I manage to produce the same results, eg. dovecot grabbing the password from the client and uses it to establish a imapc connection to the server and re-exposing it, and starts to write indexes. ( The later plan is probably to use pam as passdb to grab a and store a hashed copy of the password to allow offline access to the cached emails, but thats a later problem to solve.) What i haven't managed to get working is to trigger some replication of the remote emails to dovecot and using that as a cache to serve the emails to the client. I found some presentations and some emails that point in the direction that this should be possible to achieve, probably with the replication plugin, but never managed to get this to work. I'm using dovecot 2.2.9 Does anyone have manged to produce a working setup like this? //Anton -- Anton Lundin +46702-161604

[Dovecot] Dovecot connection problem - Too many invalid commands (no auth attempts) - v2.0.19
by Thomas Standaert 12 Dec '13

12 Dec '13

Hello. This might be a silly problem, but I'm a bit a newbie at this, and the internet didn't give me a solution to this yet. I installed a mail server with postfix, dovecot, postfixadmin and a mysql DB for authentification, using this tutorial : <http://www.exratione.com/2012/05/a-mailserver-on-ubuntu-1204-postfix-doveco t-mysql/> http://www.exratione.com/2012/05/a-mailserver-on-ubuntu-1204-postfix-dovecot -mysql/. Except step 4. The complete tutorial worked on a virtual machine, but doesn't work here on a vps from ovh.net. Connecting via telnet localhost 143 works, I can connect. When I try to connect via thunderbird, the domain name is picked up, but gives me a bad login/password combination. Mail.log, mail.err and error don't show anything. Via MS Outlook, I seem to get stuck on the connection page, and I get the following errors in mail.log: dovecot: imap-login: Disconnected: Too many invalid commands (no auth attempts): rip=x, lip=y dovecot: pop3-login: Disconnected (no auth attempts): rip=x, lip=y dovecot: imap-login: Disconnected (no auth attempts): rip=x, lip=y, TLS: Disconnected dovecot: pop3-login: Disconnected (no auth attempts): rip=x, lip=y, TLS: Disconnected dovecot: pop3-login: Aborted login (no auth attempts): rip=x, lip=y dovecot: imap-login: Disconnected (no auth attempts): rip=x, lip=y, TLS: Disconnected dovecot: imap-login: Disconnected (no auth attempts rip=x, lip=y dovecot: imap-login: Disconnected (no auth attempts): rip=x, lip=y, TLS handshaking: Disconnected dovecot: pop3-login: Disconnected (no auth attempts): rip=x, lip=y, TLS handshaking: Disconnected And after a while asks to try to connect via plain method. Doveconf -n gives me this # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-042stab068.8 x86_64 Ubuntu 12.04.2 LTS simfs auth_mechanisms = plain login first_valid_uid = 150 last_valid_uid = 150 mail_gid = mail mail_location = maildir:/var/vmail/%d/%n mail_uid = vmail passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocols = " imap pop3" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = mail mode = 0600 user = vmail } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } Hope you guys can help me, and thanks in advance for it.

[Dovecot] Selectively allow non-SSL connections based on userdb
by Trent Lloyd 12 Dec '13

12 Dec '13

Howdy Folks, I am considering transitioning our mail service over to SSL-only. As a transition mechanism, it would make sense to force all new accounts to use SSL, but still allow old accounts to go unencrypted until some transition date passes. I have done some extensive searching but could not figure a mechanism through which I could specify a setting for this in userdb or similar. Does anyone have any ideas that doesn’t involve a post-login script? Thanks, Trent

[Dovecot] Plugin development - ostream and index cache size
by Philipp Brüll 11 Dec '13

11 Dec '13

Hi, I'm new to this list, so first thanks for the dovecot tool! So far, it has been great to work with. Currently, I'm developing a scrambler plugin for dovecot, that should stores the mails encrypted. To do that, I've created the scrambler_ostream and scrambler_istream that does the encryption and that I hook in the mail storage process. The scrambler_ostream is stacked on top of the output stream of the mail_save_context (mail_save_context->data.output) and the scrambler_istream is attached to the input stream when the virtual function istream_opened in the mail_private struct is called. Basically, the encrypt/decrypt works, but during the process the data size changes slightly. And when I'm doing a FETCH BINARY[] via imap, it results in the error... Cached message size smaller than expected (204 < 208) Error: Corrupted index cache file /home/.../mail/mailboxes/INBOX/dbox-Mails/dovecot.index.cache: Broken physical size for mail UID 1 My guess is, that the FETCH function tries to deliver the unencrypted cache version of the mail (204 bytes) and not the stored version (208 bytes). How can I make dovecot cache the output of my scrambler_ostream or at least disable this caching for testing? I've read already a lot of code, but I've found a hint yet. How does - for example - the zlib plugin handle this issue? I have read the code a couple of times, but still have no clue. Best regards, Philipp

[Dovecot] OT: Large corporate email systems - Exchange vs open source *nix based
by Charles Marcus 11 Dec '13

11 Dec '13

Hello, There has been some whispers about considering migrating our mail systems to Exchange Server. I want to try to nip this in the bud. I would like to ask for some help with providing some kind of comparison of large(r) commercial companies use of email systems... specifically, those using Microsoft Exchange Server, vs those using open source Linux/Unix based systems, including even commercial *nix groupware based systems like Zimbra, as well as plain mail systems like dovecot, or cyrus or courier. I know that many (if they are smart) Admins that do use Exchange internally will use postfix (or something else linux/unix based) in front of it as their relayhost (for both inbound and outbound), so just counting the number of publicly accessible smtp servers won't be a good gauge. Does anyone know of any decent non-biased studies that have been done, hopefully relatively recently (last few years) that provide such a comparison? Thanks, -- Best regards, */Charles/*
