dovecot lda invalid user settings
by CJ Keist 10 Jul '14

10 Jul '14

I'm now dealing with issue with some users on mbox getting invalid user settings in /var/adm/messages. /var/log/syslog has: Jul 10 11:21:42 mail2 dovecot: [ID 583609 mail.error] lda(ejames): Error: user ejames: Initialization failed: Namespace '': Mail storage autodetection failed with home=/top/academic/Atmos/people/ejames/home Jul 10 11:21:42 mail2 dovecot: [ID 583609 mail.crit] lda(ejames): Fatal: Invalid user settings. Refer to server log for more information. I checked this users home directory and the mail folder is there and permissions are all correct. I'm running in a mixed mbox and Maildir environment. I read to support this environment you simply comment out the mail_location lines in 10-mail.conf file which will force dovecot to auto detect what format a user is using. This worked fine in dovecot 1.2.12, but seems to failing here. root@mail2:/userM/mail-services/dovecot/sbin# ./dovecot -n # 2.2.13: /userM/mail-services/dovecot/etc/dovecot/dovecot.conf # OS: SunOS 5.11 i86pc auth_failure_delay = 5 secs auth_mechanisms = plain login cram-md5 auth_worker_max_count = 3000 base_dir = /userM/mail-services/dovecot/var/run/dovecot/ default_client_limit = 30000 default_process_limit = 5000 disable_plaintext_auth = no hostname = mail2.engr.colostate.edu 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 duplicate 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 { driver = pam } passdb { driver = passwd } postmaster_address = cjay(a)engr.colostate.edu service auth { unix_listener /var/lib/postfix/private/auth { mode = 0666 } unix_listener auth-userdb { group = postfix mode = 0666 user = postfix } user = root } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } } service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 ssl = yes } } ssl_cert = </userM/mail-services/dovecot/etc/ssl/dovecot.pem ssl_key = </userM/mail-services/dovecot/etc/ssl/privkey.pem userdb { args = blocking=yes driver = passwd } protocol imap { mail_max_userip_connections = 50 } protocol lda { mail_plugins = sieve } protocol pop3 { mail_max_userip_connections = 50 } -- C.

Hi All, I have the Dovecot quota value coming from LDAP using the line below but my values are stored in MB, not bytes. What can I put in the line to set quotas in MB? user_attrs = homeDirectory=home,mailUID=uid,mailGID=gid,mailQuota=quota_rule=*:bytes=%$ Thanks Murray

Trigger for using an sqlite dictionary for quota
by David Anderson 10 Jul '14

10 Jul '14

Hi, I'm using Dovecot 2.0.9, and was trying to set up a dictionary process to use an sqlite database for quota management. The wiki page has examples for MySQL and PostgreSQL: http://wiki2.dovecot.org/Quota/Dict For sqlite, a trigger needs to be created to get it to work. But I was not sufficiently skilled in sqlite to adapt the PostgreSQL trigger (given on the above URL) for use. Nor did Googling find any example of anyone else who had done it. Does anyone here have an example, or the ability? (Through Googling I found an example trigger for using sqlite with expiries - but I was looking at quotas).

HIGHESTMODSEQ tracking
by Kostya Vasilyev 10 Jul '14

10 Jul '14

Hello, I'd like to follow up on someone else's old thread: http://dovecot.org/list/dovecot/2012-April/082624.html I understand that Dovecot (that 2012 discussion was about version 2.0.18) can return "HIGHESTMODSEQ 1" upon SELECT if persistent modseq tracking was never enabled for a mailbox. I'd like to get a clarification on how to enable proper persistent modseq tracking. Per RFC 4551, "A client supporting CONDSTORE.... indicates its willingness to receive mod-sequence updates... by issuing:" SELECT mailbox (CONDSTORE) STATUS (... HIGHESTMODSEQ ...) ... others ... It seems that Dovecot 2.1.7 (Debian 7.5) enables persistent modseq tracking after one of the above two commands (and maybe others). So far so good. So my questions are: 1 - Is this (enabling persistent modseq) also the case for all Dovecot versions prior to 2.1.7 that advertise CONDSTORE? There must be people running older versions out there, older than 2.1.7. If not, how can I branch my logic to not use HIGHESTMODSEQ, given that Dovecot doesn't appear to return any version info via its greeting or via the ID command? 2 - Is persistent modseq tracking (assuming it's been enabled) available for all types of backend mailbox formats that Dovecot might be using? To be more specific, can it ever be the case that Dovecot appears to enable modseq tracking, returning nice looking HIGHESTMODSEQ values from SELECT / STATUS, but the actual values get reset or not get updated because they're not properly persistent? I'm excluding changes to UIDVALIDITY here, obviously when that changes, the entire mailbox state must be assumed to have changed completely. 3 - I guess the change to return NOMOSEQ instead of "1" for mailboxes with modseq tracking disabled, as mentioned in that discussion from 2012, never happened? At least on the 2.1 branch? Thanks, -- K

Multiple email clients not in sync
by Marc Perkel 09 Jul '14

09 Jul '14

Hello everyone, I'm not sure if this is an issue with dovecot or my various email clients, or my settings. I'm running 2.2.13 and I have Thunderbird on my desktop and K@mail on my android phone. In theory if I delete email on one it should delete it on the other. It does delete it on the server - but the other client isn't always "aware" of it. Same thing sometimes with read messages. I read on one device but the other didn't know it's read unless I shut down and restart the app. Not knowing the details of how this all works I'm assuming there is some form of notification that goes on in the background so as to let other clients know what other clients do so they can sync up. And that where my setup isn't working consistently. Maybe my expectations are just too high? Maybe I don't have things set up correctly? What am I missing? Thanks in advance.

Problem with virtual mailbox when using K9 mail (android)
by Henrik Kjölhede 08 Jul '14

08 Jul '14

Hi! I've managed to setup a virtual mailbox that shows all unread or flagged mail from a selection of IMAP folders. This works great with Roundcube, which I use as webmail client. However, using K9 mail on my android phone, a mail that is opened seems to be immediately marked as read, and any flagging I do doesn't take. Presumably this is because it can't be reached any longer in the virtual folder. I tried adding the recent flag to the virtual search line, but that doesn't make any difference. I haven't been able to locate any information about anyone else experiencing this problem, so I was hoping that someone here could help. I realise that this is not exactly a "dovecot problem", but perhaps someone here has found a solution that they are willing to share. The search line in dovecot-virtual is currently "OR RECENT (OR UNSEEN FLAGGED). Regards

Limit confusion
by Micah Anderson 08 Jul '14

08 Jul '14

Hi, On one of my dovecot servers, i've got a limit problem... and I'm a little confused about which knobs I should adjust to solve it. I've been getting both of these: Error: net_connect_unix(imap) failed: Resource temporarily unavailable - http://wiki2.dovecot.org/SocketUnavailableess This one caused me to go read that wiki page, but none of those seem to apply to me: . i'm running 2.2.9 . i dont have service imap { client_limit }, although I do have service auth ( client_limit = 1024 } . my dovecot/auth process shows: dovecot/auth [91 wait, 0 passdb, 0 userdb] . it doesn't appear the master process is using very much cpu (in fact the system is mostly low load in general) . I have service_count = 0 set for imap-login for the 'high performance mode' dovecot: master: Warning: service(imap): process_limit (2560) reached, client connections are being dropped The second is because I have process_limit of 2560 for the imap service... I can raise that to 4096, but I suspect there are other limits I need to juggle? Thanks a lot for any suggestions!

Dovecot ignores existing mailboxes and creates its own
by Martin Vegter 08 Jul '14

08 Jul '14

Hello, I have Postfix with Maildir format. User's emails are being delivered into $HOME/mail/inbox Apart from ~/mail/inbox, there are the usual folders: $HOME/mail/archive $HOME/mail/drafts $HOME/mail/inbox $HOME/mail/trash Now I have installed dovecot, and set mail_location = maildir:~/mail:LAYOUT=fs additionally, I have defined mailboxes as follows: namespace inbox { mailbox drafts { special_use = \Drafts } mailbox sent { special_use = \Sent } mailbox trash { special_use = \Trash } } The problem I am having is following: 1) dovecot ignores the folders (drafts, sent, trash) and creates its own folders begining with capiotal letter: Drafts Sent Trash 2) dovecot ignores ~/mail/inbox and instead creates ~/mail/cur ~/mail/new ~/mail/tmp can somebody please advise how to tell dovecot, to use my existing folder structure, ie: ~/mail/inbox/{cur,new,tmp} ~/mail/drafts/{cur,new,tmp} ~/mail/sent/{cur,new,tmp} ~/mail/trash/{cur,new,tmp} any advice would be much appreciated thanks, Martin

08 Jul '14

I am trying to use my (decrypted) SSL key and certificate in Dovecot. I have changed /etc/dovecot/conf.d/10-ssl.conf like so: ssl_cert = </etc/ssl/private/ssl-chain-mail-mydomain.com.pem ssl_key = </etc/ssl/private/ssl-key-decrypted-mail-mydomain.com.key However, after running service dovecot restart, dovecot -n still says that the files /etc/dovecot/dovecot.pem and /etc/dovecot/private/dovecot.pem are being used. I am using dovecot 2.2.9, any help would be greatly appreciated.

doveadm quota recalc -A

Hello, It looks like my iteration SQL query (iterate_query) does not work as when I try to run "doveadm quota recalc -A" I get the following error: $ sudo -u vmail doveadm quota recalc -A doveadm(nobody): Error: user nobody: Mail access for users with UID 65534 not permitted (see first_valid_uid in config file, uid from userdb lookup). doveadm(nobody): Error: User init failed My iterate_query is quite simple: iterate_query = SELECT username FROM mailbox So from the output I really don't understand why it looks up the user "nobody". I don't have any user "nobody" in my mailbox SQL table. Anyone has an idea? Regards ML

Redis sentinel support in dict
by Lazy 08 Jul '14

08 Jul '14

Redis sentinel ( http://redis.io/topics/sentinel ) is a service that monitors and manages redis master slave replication. Using sentinel you can easily create a redis ha cluster. You can connect to a sentiniel and subscribe to certain events then in case of an failover update the redis address to new master etc. I think this is better suited to be used with dict proxy. Do You think it can be implemented without changes to dovecot core ? -- Michal Grzedzicki

dovecot 2.2.13 core dump (signal 11)
by Tom Lieuallen 08 Jul '14

08 Jul '14

We just upgraded from 2.1.16 to 2.2.13. One user is experiencing problems when using the shared namespace. Specifically it happens when opening/reading a message and when deleting messages. These functions work for other users. So far, this appears to be only affecting one user. The shared folder is a local ext4 file system and utilizes acls # 2.2.13: /private/dovecot/etc/dovecot/dovecot.conf doveconf: Warning: service auth { client_limit=1000 } is lower than required under max. load (15360) doveconf: Warning: service anvil { client_limit=1000 } is lower than required under max. load (10243) # OS: Linux 2.6.32-358.11.1.el6.x86_64 x86_64 Red Hat Enterprise Linux Server release 6.5 (Santiago) default_process_limit = 5120 first_valid_uid = 100 listen = * mail_location = mbox:~/mail:INBOX=/var/mail/%u:INDEX=/a2/imap-index/%u mail_plugins = quota acl namespace { hidden = yes inbox = no list = children location = maildir:/a1/dove-shared:INDEX=/a2/imap-index/dove-shared/%u prefix = sharedimap/ separator = / type = shared } 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 = /private/dovecot/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } passdb { args = scheme=CRYPT username_format=%u /private/dovecot/etc/passwd driver = passwd-file } plugin { acl = vfile quota = fs:INBOX:mount=/a1 quota2 = fs:Home quota:mount=%h } protocols = imap lmtp service imap-login { service_count = 1 } service imap { process_limit = 2048 } ssl_cert = </private/ssl/certs/mail.engr.oregonstate.edu.pem ssl_key = </private/ssl/certs/mail.engr.oregonstate.edu.pem userdb { args = /private/dovecot/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } userdb { args = username_format=%u /private/dovecot/etc/passwd driver = passwd-file } protocol imap { mail_max_userip_connections = 20 } Here's the backtrace in gdb.

Multiple Instances with Director
by Cassidy Larson 08 Jul '14

08 Jul '14

I have four front end servers with two backend servers. Each front end server has three instances for different mail hosts (individual SSL certs, etc). I'm looking at adding a fourth instance on each front end server for the director process. Currently we just return the backend server ip via SQL and use the old master username/password to proxy the inbound POP/IMAP sessions to the correct backend server. The plan is for each instance to have connect to the same list of director_servers (one from each front end server). What's the trick to separate a director instance into its own setup and having multiple instances/servers connect to that director? Currently I have on my proxy instance: director_servers = 10.128.1.42:9090 (this is the inet_listener from the director instance) service director { unix_listener login/director { mode = 0666 } fifo_listener login/proxy-notify { mode = 0600 user = $default_login_user } unix_listener director-userdb { mode = 0600 } } And I get in logs: director: Fatal: No inet_listeners defined for director service (for standalone keep director_servers empty) Do I need an inet_listener on the front end instance if I want to forward all director queries to the director_servers list? Or is there some other trick to get a proxy front end to talk to a separate director instance(s)? Thanks, Cassidy

question on lmtp logged message
by Leonardo Rodrigues 07 Jul '14

07 Jul '14

Hi, I have dovecot running for IMAP4/POP3 and also local delivery through LMTP. It's working just fine, absolutely no problem on that, setup is fine. Anyway, sometimes LMTP seems to not be able to deliver some messages and keep them on postfixqueue. And on the next or third try, the message gets delivered successfully. The logged message, however, is not helping me identify what is happening.Example: (error - message was expunged) Jun 25 11:49:39 correio postfix/lmtp[21835]: ADB0A1AC05108: to=<vanilson.parreira(a)domain.com.br>, relay=correio.domain.com.br[private/dovecot-lmtp], conn_use=6, delay=13, delays=0.07/0/0/13, dsn=4.2.0, status=deferred (host correio.domain.com.br[private/dovecot-lmtp] said: 451 4.2.0 <vanilson.parreira(a)domain.com.br> Message was expunged (received-date) (in reply to end of DATA command)) (successfull delivery) Jun 25 12:34:42 correio postfix/lmtp[6411]: ADB0A1AC05108: to=<vanilson.parreira(a)domain.com.br>, relay=correio.domain.com.br[private/dovecot-lmtp], delay=2716, delays=2714/0/0/2.3, dsn=2.0.0, status=sent (250 2.0.0 <vanilson.parreira(a)domain.com.br> U7pOLAHsqlPvMgAAHvf8vg Saved) During these two log entries, absolutely nothing was changed, no configuration, absolutely nothing. Everything is local, i mean, no NFS involved. So, finally, question is: what does the 'message was expunged' message given from LMTP means ??? This is happening quite often but, as i mentionted, sooner or later all messages are getting delivered. It's working despite the delay this is causing.

dbox alternate storage and samba
by Francesco 07 Jul '14

07 Jul '14

Hello everyone, i was just wondering if it's possible to use a samba share as an alternate storage for dbox format. I tried creating a samba share, but when i try to move the email to the alternate storage using doveadm altmove, no errors are printed but no mails are moved. Everything works if the alternate storage is simply another directory on the server hard drive. am i mssing something? thanks in advance.

rmdir() EBUSY warnings on 2.2.12
by Giel van Schijndel 07 Jul '14

07 Jul '14

Hi, I'm getting a lot of syslog spam on FreeBSD 10 from nfs_flush_file_handle_cache_dir where, apparently it tries to rmdir() the mountpoint of my mail storage. > Jul 4 00:04:44 mailhost dovecot: imap(user(a)example.com): Error: nfs_flush_file_handle_cache_dir: rmdir(/var/mail/vhosts/example.com) failed: Device busy We're using ZFS and have /var, /var/mail, /var/mail/vhosts, /var/mail/vhosts/example.com and /var/mail/vhosts/example.com/user as separate ZFS datasets (to enable per-user and per-domain snapshotting). So apart from NFS flushing being unnecessary (ZFS != NFS) I'm not really sure why using rmdir() for another directory than the Maildir specified in mail_location is a good idea. I.e. given that Maildirs shouldn't ever be emtpy (cur,new,tmp) anyway. -- Met vriendelijke groet, With kind regards, Giel van Schijndel -- > A programmer started to cuss > Because getting to sleep was a fuss > As he lay there in bed Looping 'round in his head > was: while(!asleep()) sheep++; > -- piercings -- http://bash.org/?845468

[help]how to refresh pigeonhole sieve vacation days data
by wuwei 07 Jul '14

07 Jul '14

hello everybody: I'm using dovecot with pigeonhole sieve Plugin.everything goes well.but when i use vacation module,i found a problem: I write a sieve with a vacation module in, and put it to the sieve location ,used *PUTSCRIPT* comand with *ManageSieve* and *set it ACTIVE*.It's work!I use A email send mail to him and receive an auto-reply.then ,I modify the sieve only change the days num from 7 to 1.Then I use B email send mail to him and receive an auto-reply too. The next day,I send two mails too.But only B receive the auto-reply.I thought that I would receive two mails too. so i think that A email's data in sieve maybe still 7 days.Then I restart the dovecot,but the problem still exsit. Is anyone know how to refresh the data or is their anyother way to solve the problem? thank you! -- View this message in context: http://dovecot.2317879.n4.nabble.com/help-how-to-refresh-pigeonhole-sieve-v… Sent from the Dovecot mailing list archive at Nabble.com.

If like from Nick Edwards suggested a imapproxy is used it will. imapproxy is keeping the connection open. doveadm who will give you a list of all actual logged in users. Without imapproxy you are right: Every page reload will cause a login and a logoff. I get some webmail users by "accident". To get an overview how many users used roudcube within a period check the database table users/last_login. Andreas

Hi all, I need to move e-mail files of my users from one file system to another. I use a MySQL backend on Dovecot 2.1. How can I do to disable temporary an account while moving files ? I have an "active" bit in my DB, but if I set it to 0, my MX servers are bouncing mails. How can I do to disable temporary an account ? In fact, I need dovecot not to do any change on files... I think I could change account password for a while, and reset it after migration, but it will disturb connected users. Maybe I could chmod 0 files on my old file system during migration ? How Dovecot will act ? Thank you :) Flo

Hello guys, After some hours fighting with shared mailbox, I finally understand how it works - and, realy, I can't believe how easy it is! So, to help others like me and to improve the shared mailbox with Dovecot this script does all the "hard work". I don't know if this group permit attachments, so, let's the link: https://sites.google.com/site/allancassaro/mkshared.tar.gz Enjoy! ===== From README file ===== This is a simple code to help with Dovecot Public Shared Mailbox function. Just configure a public shared mailbox with ACLs, change the configuration file and run this program. How it works: 1) The program connect to the LDAP server and fetch groups from it (with ldap filter) 2) With groups, it fetches the members and owners (or any attribute you want); 3) It will walk into the "shared folder" folder base directory and: 3.1) Rename any directory that was renamed in LDAP (based on entryUUID ldap attribute); 3.2) Create diretories and skeletion (new, cur and tmp) of any group that exists in LDAP; 3.3) Optionaly, remove any "orphan" directory (wihtout a ldap entrey); Example: dn: cn=Everyone,ou=Shared_Mailbox, dc=example,dc=com objectClass: labeledURIObject objectClass: top objectClass: groupOfURLs cn: Everyone labeledURI: ldap:///ou=Users,dc=example,dc=com?uid?one?(objectClass=person) member: uid=user2,ou=users,dc=example,dc=com member: uid=user3,ou=users,dc=example,dc=com member: uid=user1,ou=users,dc=example,dc=com member: uid=user.surname,ou=users,dc=example,dc=com owner: uid=user4,ou=Users,dc=example,dc=com This will create a folder tree like this: /path/toshared/.Everyone /path/toshared/.Everyone/new /path/toshared/.Everyone/cur /path/toshared/.Everyone/tmp With permission file (/path/toshared/.Everyone/dovecot-acl): user=user1 lr ... user=user.surname lr user=user4 lrwstipekxa Hope this helps you!
