[Dovecot] Maildir Seen Flags not heeded when dovecot-shared present
by J E Lyon 28 Jun '12

28 Jun '12

Hi, After many hours of searching (!) and lots of testing procmail scripts, I found the explanation I was looking for -- something you explained at http://www.dovecot.org/list/dovecot/2008-July/032551.html That explains it. Thing is, though, every time I've seen shared mailboxes -- really shared by multiple staff or not -- the preference is in fact for the shared behaviours to also "share" the Seen flags. Typically, someone doesn't want to read an email that someone else has already picked up and started dealing with or responded to. (They'll file it in due course, but the Seen flag is the first indicator that someone's opened and started to deal with it.) Hacking source code and branching and whatnot isn't easy or done lightly, but I wondered if anything else had come to light in recent years about this issue. I'd be as happy getting my procmail script to tell Dovecot to update the index based on the flag, but I'm pretty sure that's not possible :) Any ideas greatly appreciated, thanks. ~ James.

[Dovecot] last hope... public namespace and directory structure
by Daniel Fischer 28 Jun '12

28 Jun '12

hello, I would like to migrate to dovecot, but I have a problem with a public namespace declaration: # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-2-amd64 x86_64 Debian wheezy/sid And here are the relevant parts from the configuration: namespace { location = maildir:/var/mail/vhosts/%d/public prefix = Public. separator = . type = public } namespace inbox { prefix = separator = . subscriptions = yes type = private } I assume that all folders under ./public/ are public mailboxes. The public folder itself is not a maildir, but contains the team mailboxes i.e. ./public/.sales/ ./public/.service/ ./public/.purchase/ The file passwd for those 3 samples looks like this: sales@$DOMAIN::5000:5000::/var/mail/vhosts/$DOMAIN/public/.sales service@$DOMAIN::5000:5000::/var/mail/vhosts/$DOMAIN/public/.service purchase@$DOMAIN::5000:5000::/var/mail/vhosts/$DOMAIN/public/.purchase Note: All other users have mail_location /var/mail/vhosts/%d/%n Now a have the following problem: If I login in as user sales and create a folder foo and in there a folder bar. The directory structure is: ./public/. sales /.foo and /public/. sales /.foo.bar thats exactly what I´m expect. Now I logon as normal user. I can see the namespace Public with the sales mailbox but no subfolder foo or foo.bar. Now I create also the folders foo and in there bar, but the result is to me unexpected ;-): ./public/. sales ./public/. sales.foo ./public/. sales.foo.bar Looking forward to your comment, Daniel

[Dovecot] permissions on auth-userdb

28 Jun '12

Hi.. im still trying to upgrade to 2.0. Im getting: dovecot: lda: Error: userdb lookup: connect(/var/run/dovecot/auth-userdb) failed: Permission denied (euid=10000(vmail) egid=10000(vmail) missing +r perm: /var/run/dovecot/auth-userdb, euid is not dir owner) the error is correct caus its owned by root. My Questions is who should own it ? Im not sure how that works, what process/user calls the auth-userdb ? The auth-userdb returns the args generated in master.conf, right ? i think comment out the user and group setting in master.conf will fix it but im not sure if that is the securest way. the mails come from postfix via dovecot-lda Hans master.conf service auth { # auth_socket_path points to this userdb socket by default. It's typically # used by dovecot-lda, doveadm, possibly imap process, etc. Its default # permissions make it readable only by root, but you may need to relax these # permissions. Users that have access to this socket are able to get a list # of all usernames and get results of everyone's userdb lookups. unix_listener auth-userdb { mode = 0600 #user = vmail #group = vmail } auth-ldap.conf.ext passdb { driver = ldap args = /etc/dovecot/dovecot-ldap.conf.ext } userdb { driver = static args = uid=vmail gid=vmail home=/home/MAILBOXES/%u/ mail=/home/MAILBOXES/%u/mail }

[Dovecot] The deleted_to_trash Plugin (workaround Outlook 2007 behaviour)
by J E Lyon 27 Jun '12

27 Jun '12

Hi, I see this plugin exists for v1 & v2, all very interesting... Surprised no one seems to have created an RPM and it looks like deleted_to_trash is one of the very few plugins to not be shipped as part of the default install with CentOS 5.5 or CentOS 6 (i.e. Dovecot v1 & v2 respectively.) Am I missing something, or does everyone really build from source? Thanks, James.

[Dovecot] pop3-throttle
by manu＠netbsd.org 27 Jun '12

27 Jun '12

Hello I am having a hard time with users using POP while leaving mailboxes of several gigabyte cumulated. This causes a lot of disk I/O and kills performancs for everyone. I try to encourage people migrating to IMAP, but that migration will take some time, and therefore I am looking for alterantive ways to workaround the problem. I found pop3-throttle-plugin.c, which seems a smart way to solve the problem, unfortunately it comes with no documentation. I was able to build it and load it, bu itsays nothing in the logs. Is there any doc somewhere? Any advices on how to set it up? -- Emmanuel Dreyfus http://hcpnet.free.fr/pubz manu(a)netbsd.org

[Dovecot] Hardware infrastructure for email system
by Michael Wessel 27 Jun '12

27 Jun '12

Hi, I'm currently (re-)planning my email setup and have been doing some research. I have done some searches and read several threads in the areas of my questions here. While there are some that come close I haven't yet been able to get all my questions answered. I currently run a postfix, dovecot & roundcube setup and have about 2000 active accounts. I have a separate SMTP server for outbound mail and auth is done against a separate LDAP server. In front of the POP/IMAP server I have another SMTP (4 in parallel actually) server that receives and filters inbound mail through a company specific, proprietary filter before the mail hits the POP/IMAP server. LDAP & SMTP servers are ESXi VMs. So right now both dovecot and roundcube run on the same box which is a Dell PE2950 with dual quad-core Xeon, 16GB RAM and 6 1TB disks in RAID 6, so only local storage using maildir. So far it's been holding up fine, but it's beginning to show signs of overload now. I also expect an increase in users over the next few months up to somewhere between 10 - 20,000 mail boxes. Hence the re-planning. My first priority in redesigning my setup is reliability. I definitely need something fail-save and as close to always on as possible. Next is performance. And while the budget is of course limited for the moment I'm setting that aside and will worry about that when the time comes. Now here is my question(s): In order to support up to 20,000 mailboxes (distributed over several times-zones so they won't all be used at the same time) with a very reliable service with good performance, what do I actually need? Do I need(ul) SAN or is it just a "would be nice to have"? If yes, why and what would be appropriate for my needs? Or will a setup with a few more servers like the ones I already have, using something like DRBD and distributing services (imap, http, spamd etc) onto different boxes do? I know I have more reading to do on all the different options out there, but would like some input from people that have experience in this area so I can focus on the stuff that's right for my situation.

[Dovecot] doveadm proxy kick in director setups
by Tom Pawlowski 27 Jun '12

27 Jun '12

Something I noticed on a 2.1.7 director test cluster (two directors, three backends): 'doveadm proxy kick user' will kick all connections for that user on that director only. Any additional connections on other directors will remain active unless the command is run on all directors. Are the proxy and director sub-commands intended to be separate and distinct in their operation? If so, then this makes sense, as a proxy isn't necessarily a director. Are there any plans for a proxy kick equivalent that would work across directors? -- Tom Pawlowski OIT-CSS System Administrator office: Hill 145 email: tompru(a)jla.rutgers.edu phone: (732) 445-2634

[Dovecot] director map and mysql
by Костырев Александр Алексеевич 27 Jun '12

27 Jun '12

hello! Is "doveadm director map" command suppose to work when I store "host" value in mysql table? It gives me nothing in output with no errors in log. I've successfully setup directors with static passdb, and decided to give a try setup with storing host value in mysql table. The proxying is actually working, I'm just unhappy with no output from "doveadm director map". on the other hand output from "doveadm director map" is not empty, when I configure my password_query not to return host from table. director's settings in dovecot.sql is: passdb { driver = sql args = /etc/dovecot/dovecot-sql.conf } userdb { driver = sql args = /etc/dovecot/dovecot-sql.conf } director_servers = 192.168.5.125 director_mail_servers = 192.168.5.110 192.168.5.111 service doveadm { inet_listener { port = 24245 } } protocol doveadm { auth_socket_path = director-userdb } doveadm_proxy_port = 24245 in /etc/dovecot/dovecot-sql.conf at director there's password_query = SELECT \ NULL AS password,\ 'Y' as nopassword, \ 'Y' AS proxy, \ MBOX_NAME as user, \ host2 as host \ from M_MAILBOX \ where MBOX_NAME = '%u' user_query = SELECT \ MBOX_NAME AS username, \ MAIL_DIRECTORY as home \ from M_MAILBOX \ where MBOX_NAME = '%u'; iterate_query = select MBOX_NAME AS username from M_MAILBOX; backend's conf: service doveadm { inet_listener { port = 24245 } }

[Dovecot] pop3c_master_user
by Martin Schitter 27 Jun '12

27 Jun '12

the configuration keyword "pop3c_master_user" mentioned in the dsync migration documentation (http://wiki2.dovecot.org/Migration/Dsync) does not work for dovecot 2.1.7. a config line like: "pop3c_master_user = cyrus" will produce this error: doveconf: Fatal: Error in configuration file /etc/dovecot/local.conf line 33: Unknown setting: pop3c_master_user it's not defined in: src/lib-storage/index/pop3c/pop3c-settings.* is this feature not enabled with intention? btw. another question: will 'doveadm backup' mirror all the IMAP ACL information? thanks martin

[Dovecot] Dovecot performance under high load (vs. Courier)
by email builder 27 Jun '12

27 Jun '12

Hi, We are building a new system that will support a large number of users (high volume, high concurrent usage, etc). We have played with Dovecot, but in most serious applications we have traditionally used Courier IMAP. It's my (lay) understanding that with indexing and perhaps other things in Dovecot, it might perform better than Courier in larger environments like this. Am I correct or is it less clear-cut? Any tips on making the migration (not migrating an existing system, I mean migrating our paradigm - things to consider, things to watch out for)? TIA

[Dovecot] Virtual users - what is better Maildir or mbox?
by Kaya Saman 26 Jun '12

26 Jun '12

Hi, I'm trying to configure a server to use SAMBA and Winbind to authenticate to Active Directory.... I managed to get this portion up and running even the Dovecot portion. For reference something similar to this guide: http://www.whitneytechnologies.com/?p=119 However PAM is slightly different: # cat /etc/pam.d/dovecot auth sufficient pam_krb5.so no_user_check validate account sufficient pam_permit.so This is what my dovecot.conf file looks like: # cat dovecot.conf # v1.2+: auth_use_winbind = yes auth_winbind_helper_path = /usr/local/bin/ntlm_auth protocols = imap # It's nice to have separate log files for Dovecot. You could do this # by changing syslog configuration also, but this is easier. log_path = /var/log/dovecot.log info_log_path = /var/log/dovecot-info.log # Disable SSL for now. ssl = no disable_plaintext_auth = no # We're using Maildir format #mail_location = maildir:~/Maildir mail_location = mbox:/mail:INBOX=/mail/%u # Authentication configuration: auth_verbose = yes auth_debug = yes auth_username_format = %n auth_mechanisms = plain ntlm login userdb { driver = static # args = uid=501 gid=1001 home=/mail/%u args = home=/mail/%u driver = static } passdb { driver = pam args = failure_show_msg=yes } Now what I would like to know is, which is better for "virtual hosting" Maildir or mbox? Basically my requirement is that I would like to separate users via either individual folders and then put each user's mbox or Maildir in the created directory, or simply name each mbox or Maildir according to the user name. First up is this possible? Secondly, how would I go about doing it? My users are not allowed to login to the system outside of IMAP as it's a Mail only server. Currently I've been looking at many links: http://satish-linuxbug.blogspot.co.uk/2008/08/freebsd-with-active-directory… http://joseph.randomnetworks.com/2005/11/08/freebsd-users-and-groups-with-s… http://wiki2.dovecot.org/HowTo/ActiveDirectoryNtlm http://wiki2.dovecot.org/Authentication/Mechanisms/Winbind http://wiki2.dovecot.org/TestInstallation http://wiki2.dovecot.org/VirtualUsers http://www.linuxmail.info/active-directory-dovecot-pam-authentication/ http://wiki2.dovecot.org/HowTo/SimpleVirtualInstall I'm running dovecot version 2.1.7 on FreeBSD 8.2 x64 RELEASE. The system is not being used as an MTA server meaning that only IMAP transfers are being done using MS Outlook then filtered by Thunderbird. Regards, Kaya

[Dovecot] specifying home/sieve/sieve_dir relative to mail_location
by Edgar Fuß 25 Jun '12

25 Jun '12

With 1.2, is it possible to specify home, sieve and sieve_dir relative to mail_location? I have mail_location = maildir:/import/mail/%n/:INDEX=/var/db/dovecot/indexes/%n and, in the plugin section, home = /import/mail/%n/home sieve = /import/mail/%n/dovecot.sieve sieve_dir = /import/mail/%n/sieve I would like to partially move users to another location (different file server) by using an LDAP entry. I know it's possible to specify everything relative to home, so I could probably use relative ~/../-type paths for mail_locatin etc., but that looks a bit awkward. The VirtualUsers/Home Wiki enty contains an example for relative paths user_attrs = .., mailDirectory=home=/var/vmail/%$ which I do not understand.

[Dovecot] 2.1.7 TLS issues
by Christian Rößner 25 Jun '12

25 Jun '12

Hi, I have an interesting problem: I am building dovecot packages for Ubuntu since 10.04. Never had bigger trouble with it. Now since 2.1.6 or 2.1.7 (I can not say more precisely), Thunderbird 10ESR and Outlook 2010 can no longer use 143/TLS correctly. Automx delvers 143/TLS and Outlook tells me that it can not create a secure connection. I changed automx to use 993/SSL and everything works. Under Thunderbird 10ESR, I get a box that tells me that I need to change settings. When I sent mail, TB told me that it could not copy the mail to the sent folder. I also changed to 993/SSL and everything is perfect. At the other and, Apples Mail.app and iOS devices work perfectly over 143/TLS. So my guess is that it has to do with OpenSSL. Did something change in dovecot concerning TLS? Can I change options in the built process?

[Dovecot] Dovecot Quotas in Version 2
by Brian Spraker 24 Jun '12

24 Jun '12

Hello all, Just upgraded from Ubuntu 10.04 to 12.04 on a server today and went through a few issues that I finally got corrected with many different services. However, one of them - I absolutely cannot figure out. I was using Dovecot 1 in Ubuntu 10.04 - but in Ubuntu 12.04, it has been upgraded to Dovecot 2. Finally managed to get the configuration to work and get it to use MySQL as the back-end authentication method (had to install the dovecot-mysql package). But, I cannot get quotas to work. The moment I uncomment a quota line, Dovecot fails to start. Would appreciate any help with this. I am not using any of the individual configuration files on the conf.d folder - simply the dovecot.conf and dovecot-sql.conf file. Here is a copy of those. You can see the one commented line (mail_plugins under imap) simply will not work - but yet the one under POP works (although I don't think it is used): base_dir = /var/run/dovecot/ disable_plaintext_auth = no first_valid_uid = 33 last_valid_uid = 33 listen = * log_timestamp = "%Y-%m-%d %H:%M:%S " mail_privileged_group = www-data passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { quota = maildir quota_rule = Trash:storage=100M } protocols = imap pop3 service auth { user = root } service imap-login { executable = /usr/lib/dovecot/imap-login } service imap { executable = /usr/lib/dovecot/imap } ssl = no userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocol imap { imap_client_workarounds = mail_plugin_dir = /usr/lib/dovecot/modules/imap # mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota pop3_uidl_format = %08Xu%08Xv } And for the dovecot-sql.conf file (passwords changed, of course): driver = mysql connect = dbname=horde user=<USER> password=<PASSWORD> host=localhost default_pass_scheme = PLAIN password_query = SELECT user_uid as user, user_pass as password FROM horde_users WHERE user_uid = '%u'; user_query = SELECT uid, gid, home, maildir, concat('maildir:storage=', quota) AS quota FROM horde_users WHERE user_uid = '%u'; I did not update the dovecot-sql.conf file at all - so I don't know if there maybe be some configuration issue with how it is pulling the quota limit from the database. Quotas are in bytes in the database. Certainly would appreciate any help with this. I went through the Dovecot Quota Configuration in the wiki but it wasn't any help - as I basically already have that line in the config file, but it will fail to start Dovecot. Thank you! Brian S.

[Dovecot] Problems getting auto create plugin to work
by Dr Josef Karthauser 23 Jun '12

23 Jun '12

Hi there, I've configured the 'autocreate' plugin (in v.2.1.6), but it doesn't appear to be working. Can someone help me work out how to work out why please? I've got this in my 20-imap.conf file: protocol imap { mail_plugins = $mail_plugins antispam autocreate } and this in my 90-plugins.conf file: plugin { autocreate = Trash autocreate2 = Spam autosubscribe = Trash autosubscribe2 = Spam ... etc } But, the spam does not get created upon login. I've restart dovecot and restarted my mail client, but there's no hint of an spam folder. Is there something else that I also need to do? Thanks, Joe

[Dovecot] Import from Evolution
by Jonathan Ryshpan 23 Jun '12

23 Jun '12

I need to import the mail database generated by the evolution mail reader into dovecot. Evolution stores its mail in maildir format (fully standards compatible, I think); I would be using the maildir format in dovecot. Is there anything in the wiki, etc. explaining exactly how to do this? Why do this? Evolution is hopelessly broken, and is not likely to be fixed in the forseeable future, and I would like to keep my mails in maildir form. Reviews of kmail are very bad, and thunderbird uses the mbox format for storage. Thanks in advance - jon

[Dovecot] cumulative userdb ?
by Benoit Branciard 22 Jun '12

22 Jun '12

in Dovecot 2.0, is it possible to have kind of "cumulative" multiple userdb ? that is, for all users: - extract some attributes (let's say: uid, gid, home) from a first userdb (Passwd for example), - an extract some other attributes (mail for example, but overwriting those from the first userdb in case of redundancy) from a second userdb (LDAP for example) ? This is *different* from the "multiple databases" setup described in http://wiki2.dovecot.org/Authentication/MultipleDatabases, where it is meant as "failover": the second database is looked up only if the user isn't found in the first database. -- Benoit BRANCIARD Service InfraStructures (SIS) - Direction du Système d'Information (DSI) Université Paris 1 Panthéon-Sorbonne Centre Pierre Mendès France B 406 - 90, rue de Tolbiac - 75634 Paris cedex 13 - France Tél : +33 1 44 07 89 68 - Fax : +33 1 44 07 89 66 Accueil tél. : +33 1 44 07 89 65 Assistance : assistance-dsi(a)univ-paris1.fr Web : http://dsi.univ-paris1.fr -- Ce message a ete verifie par MailScanner pour des virus ou des polluriels et rien de suspect n'a ete trouve.

[Dovecot] Dovecot LDA, Offlineimap and Sieve
by Johnny 22 Jun '12

22 Jun '12

Hi, I am trying to st up Offlineimap to use Dovecots LDA to be able to use Sieve for mail filtering, but am not sure how to get this working. I think the right way would be to use 'preauthtunnel' in .offlineimaprc and try the setup below, which doesn't work. ,----.offlineimaprc | [Repository LocalRepository] | type = IMAP | preauthtunnel = ssh -q localhost '/usr/libexec/dovecot/deliver -d myloginid' `---- If I go via the network card, the snch is fine, but Sieve can't be used? ,---- | [Repository LocalRepository] | type = IMAP | preauthtunnel = MAIL=maildir:$HOME/Maildir/myMailDir /usr/libexec/dovecot/deliver -d mylogonid | remotehost = localhost | port = 143 | remoteuser = mylogonid | remotepass = mypassword `---- Has anyone got any tips on how to get offlineimap to send mail to Dovecot in a way that Siev3e can be used? thanks! -- Johnny

[Dovecot] LDA vs maildrop... LDA *and* maildrop?
by email builder 22 Jun '12

22 Jun '12

We're considering a move from Courier to Dovecot. So far, looks like it's not too bad, but the most challenging obstacle is what to do about our local delivery. Factors: 1. we use a lot of maildrop "features" that are impossible in sieve without piping to an external program (would rather not re-write our working maildrop scripts in another language) 2. would love to try dbox 3. we use IMAP/Maildir++ quotas (looks like with a little finesse it's possible to get maildrop and dovecot to play nice on this account, yes?) I saw it suggested to just call LDA from maildrop for any maildrop "to" commands (hmmm, what about "cc"?) here: http://article.gmane.org/gmane.mail.imap.dovecot/56120 How much overhead will this take? Would it be possible or advisable to use LMTP instead if that would help? Is this idea just too crazy?

[Dovecot] Manual manipulation of Sieve files
by email builder 22 Jun '12

22 Jun '12

We have some scripts that take care of some tasks when creating new email accounts, such as creating some default mail filter rules. I know Sieve scripts are plain text files, but need to be compiled for use. I see that you can use seivec to compile scripts manually, which can help me create .dovecot.svbin which can be placed where needed and permissioned correctly. But a couple questions: * Sieve has the concept of an active script - is this merely whatever is compiled into the .dovecot.svbin file? * Does dovecot (managesieve) do any other housekeeping when a user sieve script is installed and set as the active script? I would need to replicate this manually. * If the default script is always the same (sorry, for us, the solution isn't global scripts), would it work to compile that script once, keep the compiled version somewhere and merely copy it into the correct place for a new user? Are there issues with this? * Should we always have the plain text version along with the compiled one for proper managesieve operation going forward (users can edit their sieve scripts) Thank you

[Dovecot] Dovecot proxy/director and mail pop3/imap backend service on same server
by Aerion Stevens 22 Jun '12

22 Jun '12

Hi all, I am interested in running a Dovecot Proxy(with Director) on the same server as the main Dovecot IMAP/POP3 service. I have a basic Proxy/Director configuration working, however I am struggling with getting the Proxy and IMAP/POP3 service to coexist on the same server. I plan to use three IMAP/POP3 servers with a NFS/maildir backend, and I am playing with Dovecot 2.1.5 at the moment. I have two seperate configurations, one for the Proxy/Director and one for the Dovecot IMAP/POP3 "mail backend servers". For this to work my thoughts are that I will need to run the Proxy/Director imap/pop3 login process on the standard ports 143, 110, 993, 995 and for the Dovecot IMAP/POP3 mail backend service running on the same server will need to use different ports (I decided to be 9143, 9110, 9993, 9995 for example). How do I tell the director to proxy incoming imap/pop3 connection to the mail backend servers running on ports 9143, 9110, 9993, 9995 rather than the default imap/pop3 ports? Using the default ports will clearly cause loops. Can anyone kindly provide an example snippet of config that tells the director to use different port for IMAP and POP3 proxy? I have so far found the following pages helpful to what I am working on: http://wiki2.dovecot.org/PasswordDatabase/ExtraFields/Proxy http://wiki2.dovecot.org/PasswordDatabase/ExtraFields http://wiki2.dovecot.org/Director Cheers, Aerion.

[Dovecot] GlusterFS + Dovecot
by Romer Ventura 22 Jun '12

22 Jun '12

Hello, Has anyone used GlusterFS as storage file system for dovecot or any other email system..? It says that it can be presented as a NFS, CIFS and as GlusterFS using the native client, technically using the client would allow the machine to read and write to it, therefore, I think that Dovecot would not care about it. Correct? Anyone out there used this setup?? Thanks.

[Dovecot] dovecot 2.1.5 performance
by Angel L. Mateo 21 Jun '12

21 Jun '12

Hello, I'm migrating from 1.1.16 running in 4 debian lenny servers virtualized with xenserver and 1 core and 5GB of RAM to 2.1.5 running in 4 ubuntu 12.04 servers with 6 cpu cores and 16GB of RAM virtualized with VMWare, but I'm having lots a performance problems. I don't think that virtualization platform could be the problem, because the new servers running in xenserver has the same problems than running in vmware. I have about 70000 user accounts, most of them without real activity (they are students who doesn't read his email or have its account redirected to other provider). I have about 700-1000 concurrent imap connections. I have storage in nfs (nfsv3, the nfs server is a celerra), but indexes are in local filesystems (each server has its own index fs). Mailboxes are in maildir format. Old servers and actual director servers are load balanced with an radware appdirector load balancer (the new backend servers don't need to be balanced because I'm using a director farm) In the old platform I have scenario number 2 described at http://wiki2.dovecot.org/NFS, but in the new ones I have a director proxy directing all connections from each user to the same server (I don't specify any server for the user, director selects it according to the hash algorithm it has). Some doubts I have for the recommended in that url: * mmap_disable: both single and multi server configurations have mmap_disable=yes but in index file section says that you need it if you have your index files stored in nfs. I have it stored locally. Do I need mmap_disable=yes? What it's the best? * dotlock_use_excl: it is set to no in both configurations, but the comment says that it is needed only in nfsv2. Since I have nfs3, I have it set it to yes. * mail_nfs_storage: In single server is set to no, but in multi server it set to yes. Since I have a director in front of my backend server, what is the recommended? With this configuration, when I have a few connections (about 300-400 imap connections) everything is working fine, but when I disconnect the old servers and direct all my users' connections to the new servers I have lot of errors. server loads increments to over 300 points, with a very high io wait. With atop, I could see that of my 6 cores, I have one with almost 100% waiting for i/o and the other with almost 100% idle, but load of the server is very, very high. With the old servers, I have performance problems, access to mail is slow, but it works. But with the new ones it doesn't work at all. Any idea? -- Angel L.

[Dovecot] public namespace
by Daniel Fischer 21 Jun '12

21 Jun '12

Hello, dovecot -n # 2.0.18: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-2-amd64 x86_64 Debian wheezy/sid mail_gid = 5000 mail_location = maildir:~:INDEX=/var/mail/indexes/%d/%n mail_privileged_group = vmail mail_uid = 5000 namespace { hidden = no inbox = yes list = yes location = prefix = separator = / subscriptions = yes type = private } namespace { list = children location = maildir:/var/mail/vhosts/%d/public:INDEX=/var/mail/indexes/%d/%n/public prefix = Public/ separator = / subscriptions = no type = public } i´m a little bit confused but I hope I find help here. The user mailboxes work perfectly just the public mailbox is a little bit tricky I expect that all public maildirs be placed under /var/mail/vhosts/%d/public. They are created by defining a public namespace, under which all the shared mailboxes are. For those special users, I have set the maillocation via passwd file to /%d/public/%n, all other users have /%d/%n. So we have following folder structure \public \public\.info \public\.lager \public\.buchhaltung And so on Thats works fine, but with subfolder start the problems. When the info-user loggs on and creates a subfolder under his INBOX(called hust2) then no other people can see this. Otherside, if a normal user creates a folder in public folder info(called hust), the info user can´ t see this one. If I look to filesystem, the reason is clear: %d/public/.info# ls -la insgesamt 32 drwx--S---+ 2 vmail vmail 6 Jun 19 11:50 cur -rwxrwx---+ 1 vmail vmail 51 Jun 21 09:50 dovecot-uidlist -rw-rw----+ 1 vmail vmail 8 Jun 19 11:51 dovecot-uidvalidity -r--r-----+ 1 vmail vmail 0 Jun 19 11:50 dovecot-uidvalidity.4fe04b06 drwx--S---+ 5 vmail vmail 78 Jun 19 11:54 .INBOX.hust2 drwx--S---+ 2 vmail vmail 6 Jun 19 11:50 new -rw-rw----+ 1 vmail vmail 18 Jun 19 11:51 subscriptions drwx--S---+ 2 vmail vmail 6 Jun 19 11:50 tmp drwx--S---+ 5 vmail vmail 78 Jun 21 09:51 .Trash %d/public# ls -la insgesamt 16 -rw-rw----+ 1 vmail vmail 8 Jun 19 11:51 dovecot-uidvalidity -r--r-----+ 1 vmail vmail 0 Jun 19 11:51 dovecot-uidvalidity.4fe04b36 drwx--S---+ 7 vmail vmail 4096 Jun 21 09:50 .info drwx--S---+ 5 vmail vmail 78 Jun 21 09:51 .info.hust A look to the info mailbox makes it clear: info@BLABLA \INBOX \hust2 >create by info user in his mailbox \Trash \Public \info >his own public share \hust >create by other user in public folder What I need is: %d/public/lager/cur %d/public/lager/new %d/public/lager/tmp %d/public/lager/.foo %d/public/lager/.foo.bar %d/public/ info /cur %d/public/ info /new %d/public/ info /tmp %d/public/info/.hust %d/public/info/.hust.deeperhust %d/public/info/.hust2 All public maildirs under /%d/public/%n Must I create a namespace for all public maildirs?: namespace { location = maildir:/var/mail/vhosts/%d/public/info } namespace { location = maildir:/var/mail/vhosts/%d/public/lager } I can´ t figure out on my own, please give me an explanation.

[Dovecot] Dovecot not liking AD config from wiki??
by Kaya Saman 21 Jun '12

21 Jun '12

I think the issue seems to be the mechanism between Dovecot and AD, so basically PAM..... I adapted my pam.d file to this: # auth auth sufficient pam_krb5.so no_warn try_first_pass debug #auth sufficient pam_ssh.so no_warn try_first_pass auth required pam_unix.so no_warn try_first_pass # account #account required pam_nologin.so #account required pam_unix.so account required pam_krb5.so in the hope that this config would work: userdb { driver = static args = uid=501 gid=501 home=/mail/%u driver = static # args = uid=500 gid=500 home=/ZPOOL_1/%u # allow_all_users=yes } passdb { driver = pam } However I am still having issues :-( Regards, Kaya

[Dovecot] Problem with Dovecot 2.0/2.1 and MySQL 5.1
by Mark Schmale 20 Jun '12

20 Jun '12

Hi everyone, since some time I got problems with dovecot & mysql. I got the problem with version 2.0.x and upgraded to 2.1.7 to check if its gone. But its not :( The logs just tell me this: dovecot: auth: Error: auth worker: Aborted request: Worker process died unexpectedly If I change to a sqlite setup, everything works fine. Here are some informations. I hope someone can tell me whats wrong with my system/setup. I really dont think that this is a bug because someone else should have hit that before me. doveconf - n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.2-hardened-r1 x86_64 Gentoo Base System release 2.1 auth_verbose = yes mail_location = maildir:~/%d/mail/%n 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 { 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 = } passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap pop3 lmtp sieve service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = vmail user = vmail } } ssl_cert = </etc/ssl/dovecot/server.pem ssl_key = </etc/ssl/dovecot/server.key userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocol lda { mail_plugins = sieve } contents of dovecot-sql.conf: default_pass_scheme = PLAIN-MD5 driver = mysql connect = host=localhost dbname=config user=user password=pass password_query = SELECT CONCAT( u.username, '@', d.name ) AS user, password FROM mail_user AS u LEFT JOIN mail_domains AS d ON u.domain = d.id WHERE u.username = '%n' AND d.name = '%d' user_query = SELECT home, uid, gid FROM mail_user AS u LEFT JOIN mail_domains AS d ON u.domain = d.id WHERE u.username = '%n' AND d.name = '%d' // linebreaks added by mailclient for readability bt full with gdb: [Thread debx7fb891e85977 "216be49381eb03d180103cdf6eb90483" fields_count = 2 name = 0x0 #1 sql_query_callback (result=0x7fb891e82f60, sql_request=0x7fb891e82c08) at passdb-sql.c:87 auth_request = 0x7fb891e82a80 _module = <optimized out> module = <optimized out> passdb_result = PASSDB_RESULT_INTERNAL_FAILURE password = 0x0 scheme = <optimized out> ret = <optimized out> __FUNCTION__ = "sql_query_callback" #2 0x00007fb891c3c940 in driver_sqlpool_query_callback (result=0x7fb891e82f60, request=0x7fb891e82e50) at driver-sqlpool.c:635 db = 0x7fb891e66540 conn = 0x0 conndb = 0x7fb891e66910 #3 0x00007fb891c3dbe0 in driver_mysql_query (db=<optimized out>, query=<optimized out>, callback=0x7fb891c3c8c0 <driver_sqlpool_query_callback>, context=0x7fb891e82e50) at driver-mysql.c:296 result = 0x7fb891e82f60 #4 0x00007fb891c3cc41 in driver_sqlpool_query (_db=0x7fb891e66540, query=0x7fb891e561c8 "SELECT CONCAT( u.username, '@', d.name ) AS user, password FROM mail_user AS u LEFT JOIN mail_domains AS d ON u.domain = d.id WHERE u.username = 'masch' AND d.name = 'masch.it'", callback=0x7fb891c31960 <sql_query_callback>, context=0x7fb891e82c08) at driver-sqlpool.c:657 db = 0x7fb891e66540 request = 0x7fb891e82e50 conn = 0x7fb891e667c0 #5 0x00007fb891c23b49 in auth_worker_handle_passv (args=0x7fb891e560b8, id=1, client=<optimized out>) at auth-worker-client.c:200 auth_request = 0x7fb891e82a80 passdb = <optimized out> password = 0x7fb891e55ff2 "somepassword" passdb_id = 1 #6 auth_worker_handle_line (line=<optimized out>, client=<optimized out>) at auth-worker-client.c:559 args = out>0x7fb891e560a8 id = 1 ret = false #7 auth_worker_input (client=0x7fb891e80650) at auth-worker-client.c:647 _data_stack_cur_id = 3 line = <optimized out> ret = true #8 0x00007fb89179f4b6 in io_loop_call_io (io=0x7fb891e80970) at ioloop.c:379 ioloop = 0x7fb891e5e390 t_id = 2 #9 0x00007fb8917a043f in io_loop_handler_run (ioloop=<optimized out>) at ioloop-epoll.c:213 ctx = 0x7fb891e69100 events = <optimized out> event = 0x7fb891e69170 list = 0x7fb891e809c0 io = <optimized out> tv = {tv_sec = 59, tv_usec = 999508} msecs = <optimized out> ret = 1 i = <optimized out> j = <optimized out> call = <optimized out> #10 0x00007fb89179ed50 in io_loop_run (ioloop=0x7fb891e5e390) at ioloop.c:398 No locals. #11 0x00007fb891786a87 in master_service_run (service=0x7fb891e5e240, callback=<optimized out>) at master-service.c:544 No locals. #12 0x00007fb891c289a3 in main (argc=2, argv=0x7fb891e5e080) at main.c:373 c = <optimized out> best regards, Mark Schmale

[Dovecot] Dovecot not liking AD config from wiki??
by Kaya Saman 20 Jun '12

20 Jun '12

Hi, I'm trying to setup Dovecot with MS AD and am using this as my guide: http://wiki2.dovecot.org/HowTo/ActiveDirectoryNtlm I can definitely access information on the AD server using wbinfo -g and wbinfo -u..... Currently my dovecot.conf file looks like this: # v1.1: #auth_ntlm_use_winbind = yes # v1.2+: auth_use_winbind = yes auth_winbind_helper_path = /usr/local/bin/ntlm_auth protocols = imap # It's nice to have separate log files for Dovecot. You could do this # by changing syslog configuration also, but this is easier. log_path = /var/log/dovecot.log info_log_path = /var/log/dovecot-info.log # Disable SSL for now. ssl = no disable_plaintext_auth = no # We're using Maildir format #mail_location = maildir:~/Maildir mail_location = mbox:/mail:INBOX=/mail/%u # If you're using POP3, you'll need this: #pop3_uidl_format = %g # Authentication configuration: auth_verbose = yes auth_debug = yes auth_username_format = %n auth_mechanisms = plain ntlm login userdb { driver = static args = uid=501 gid=501 home=/mail/%u driver = static allow_all_users=yes } According to the documentation I should be using: userdb static { ... } which seems to be Dovecot v1. config, and additionally the "allow_all_users=yes" statement when added seems again v1. config since Dovecot 2. won't even start? In the meantime when not using "allow_all_users" Dovecot throws up these errors: Jun 20 11:30:40 master: Warning: Killed with signal 15 (by pid=4149 uid=0 code=kill) Jun 20 11:30:48 auth: Fatal: No passdbs specified in configuration file.

[Dovecot] Very High Load on Dovecot 2 and Errors in mail.err.
by Urban Loesch 20 Jun '12

20 Jun '12

Hi, I have a DELL PE R610 (32GB RAM 2x Six Core CPU and about 1,4 TB RAID 10) running with 20.000 Mailaccounts behind 2 Dovecot IMAP/POP3 Proxies on a Debian Lenny. The Server was running about 1 year without any problems. 15Min Load was between 0,5 and max 8. No high IOWAIT. CPU Idletime about 98%. But since yesterday morning the Systemload on the Server has been increased over 500. I Think this is very high. The strange thing: there was no IOWAIT and the CPU Idle time was allways the same on about 98%. The total amount of IMAP Sessions is about 300 - 600.

HI I'm tryin to set up sieve the way so it will put incoming message into Junk folder, which is described via namespace. Unfortunately rule doesn't work and message is put into Inbox. If i change destination folder to folder not described via namespace in the same rule the message is placed to that folder. please help dovecot 1.2.9 namespace: type: private prefix: Junk/ location: maildir:/opt/mail/Junk/INBOX:LAYOUT=fs hidden: yes list: yes subscriptions: yes

[Dovecot] message parser: Fixed infinite loop when parsing a specific message.
by Timo Sirainen 20 Jun '12

20 Jun '12

I committed this change to all hg branches: http://hg.dovecot.org/dovecot-2.1/rev/4461b48fcc1f After that I realized that it doesn't actually matter, because it fixes only a situation where input buffer's size is less than 84 bytes. This happened on a test program where I was using a 64 byte buffer, but the real code in Dovecot always uses much larger buffers. So, don't worry, there's no way to actually DOS Dovecot with this. No need for distro people to create any security releases.

[Dovecot] doveadm fetch LARGE attachments and remove message
by Bradley Giesbrecht 19 Jun '12

19 Jun '12

Looking at the wiki and man pages I am unsure how to fetch email attachments from a unix shell. I have an "doveadm search" that returns the messages that have the attachments I am after. Would I loop through an "doveadm fetch" and use a commandline imap client to save the attachments and move the message to the Trash? Or is there a doveadm command for this? Regards, Bradley Giesbrecht (pixilla)

[Dovecot] dovecot-sieve and LMT
by Martin Weil 19 Jun '12

19 Jun '12

Dear list, My mail server is working perfectly. So I am trying to add feature after feature, until I have all the features I need. This has worked fine until now. I am trying to get dovecot-sieve to work. So I activated dovecot-lda and the sieve plugin and told postfix to use deliver instead of procmail. After restarting all services I then created a test sieve file. Obviously I have not yet understood the whole process completely because, it simply does not work. I suspect some permission problems or misconfiguration of the sieve file, but I am not sure where to look for solutions. -rw-r--r-- 1 2001 2001 116 2012-06-16 21:25 /var/mail/vmail/domain.com/user/dovecot.sieve dovecot.sieve require "fileinto"; if header :contains ["subject"] ["Test"] { fileinto ".Folder1"; } else { fileinto ".Folder2"; } Of course Folder1 and Folder2 do exist. (/var/mail/vmail/domain.com/user/mail/.Folder1 and Folder2) As far as I can tell there are no errors reported anywhere, I checked mail.log and syslog. 2001 is the virtual uid/gid of this particular user. If anyone can help me with this it would be great. The Mailserver works very well apart from this. There was one odd thing apart from this. In the docs I read that auth-master has to be running for deliver to work correctly. I did not know this before, but mails were delivered correctly after I started using deliver. So is there a need for auth-master to be running or not?

[Dovecot] question about fts_squat
by Wojciech Puchar 18 Jun '12

18 Jun '12

just installed dovecot with fts_squat config attached after message. When i telnet to imap server and execute by hand 1 login user password select foldername search body "someword" it works fine, and at blazing speed except first run (indexing). i already indexed everything by doveadm index offline to prevent server overload if multiple users (after i tell them) will try fulltext search. All great BUT it doesn't work in thunderbird. Just gives zero results. i used tcpdump to check how thunderbird executes it and it uses search undeleted body "someword" tried manually and it DOES NOT WORK. always give empty results. even search all body "someword" doesn't work. while search body "someword" always work very well. what's wrong? # 2.1.7: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.3-STABLE amd64 disable_plaintext_auth = no listen = * mail_location = maildir:~/Maildir mail_plugins = fts fts_squat 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 = } passdb { args = /usr/local/etc/dovecot/deny-users deny = yes driver = passwd-file } passdb { driver = pam } plugin { fts = squat fts_squat = partial=4 full=10 } protocols = imap ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } protocol imap { mail_plugins = fts fts_squat }

[Dovecot] Problem with lmtp director proxy
by Angel L. Mateo 18 Jun '12

18 Jun '12

Hi, I have a timeout problem only when I have heavy load in my system. I have two director servers directing to 4 backend servers. The problem is when my smtp relays tries to deliver mail to my users via lmtp (proxied with director). In the smtp logs I have: Jun 12 11:41:18 xenon13 postfix/lmtp[4248]: 4433E5D5A0: to=<myuser(a)um.es>, relay=pop.um.es[155.54.212.106]:24, delay=31, delays=0.41/0.06/0/30, dsn=4.4.0, status=deferred (host pop.um.es[155.54.212.106] said: 451 4.4.0 Remote server not answering (timeout while waiting for reply to DATA reply) (in reply to end of DATA command)) If I look for this connection in the director servers I have: Jun 12 11:40:39 myotis41 dovecot: lmtp(6595): Connect from 155.54.212.167 Jun 12 11:40:39 myotis41 dovecot: lmtp(6595): Debug: auth input: user=user1 proxy host=155.54.211.163 proxy_refresh=450 Jun 12 11:40:39 myotis41 dovecot: lmtp(6595): Debug: auth input: user=user2 proxy host=155.54.211.163 proxy_refresh=450 .... (more users, a total of 34 recipients) Jun 12 11:40:39 myotis41 dovecot: lmtp(6595): Debug: auth input: user=myuser proxy host=155.54.211.164 proxy_refresh=450 ... Jun 12 11:41:09 myotis41 dovecot: lmtp(6595): Disconnect from 155.54.212.167: Client quit (in reset) and in one of the final server (the one for the user in question): Jun 12 11:40:38 myotis34 dovecot: lmtp(16824): Connect from 155.54.211.186 Jun 12 11:40:38 myotis34 dovecot: lmtp(16824, <user1>): wJ9BD7YM10 +4QQAAG5O5Qg: sieve: msgid=<182283367.48.1339494011054.JavaMail.tomcat@sakai-prod4>: stored mail into mailbox 'INBOX' ...

Jun 12 11:41:11 myotis34 dovecot: lmtp(16824): Disconnect from 155.54.211.186: Connection closed (in reset) So the mail seems to be correctly delivered in about 30 seconds. All my postfix timeouts are bigger than this time: lmtp_connect_timeout = 0s lmtp_connection_cache_time_limit = 2s lmtp_connection_reuse_time_limit = 300s lmtp_data_done_timeout = 600s lmtp_data_init_timeout = 120s lmtp_data_xfer_timeout = 180s lmtp_lhlo_timeout = 300s lmtp_mail_timeout = 300s lmtp_pix_workaround_delay_time = 10s lmtp_pix_workaround_threshold_time = 500s lmtp_quit_timeout = 300s lmtp_rcpt_timeout = 300s lmtp_rset_timeout = 20s lmtp_sasl_auth_cache_time = 90d lmtp_starttls_timeout = 300s lmtp_tls_session_cache_timeout = 3600s lmtp_xforward_timeout = 300s So... why do I have this error? As a side effect this mail was delivered twice in the user's mailbox, this is one and the other when postfix retries again. Any help? Thank you -- Angel L.
