migrating servers
by chris 23 Aug '15

23 Aug '15

Hi I am trying to migrate from a Centos dovecot 1.0.7 install to a debian dovecot 2.1.7 install. I thought simply replicating the maildirs would be fine (using rsync) but when I fetch mail from the new server using IMAP thunderbird wants to download all the messages again as duplicates. I searched the wiki over to see if I could find a solution and while it appeared I could use doveadm backup that seems to only work pushing changes from the new server to the old (wrong direction) and that program does not exist on the earlier version of dovecot on the old server. If I can be very blunt the documentation on the wiki assumes far too much knowledge from the reader. It is often hard to decipher exactly what is meant by many of the obtuse instructions. But that is an aside can anyone give me pointers on how to do this migration for all my users so they don't need to sort through hundreds of duplicated emails? Chris

Delivering email to Maildir PreINBOX
by Paulo Matos 22 Aug '15

22 Aug '15

Hi all, I have a running dovecot with: $ dovecot -n # 2.2.18: /etc/dovecot/dovecot.conf # OS: Linux 4.1.0-x86_64-linode59 x86_64 Fedora release 22 (Twenty Two) ext4 auth_debug = yes auth_mechanisms = plain login digest-md5 cram-md5 auth_verbose = yes auth_verbose_passwords = yes default_internal_user = root imap_client_workarounds = delay-newmail tb-extra-mailbox-sep mail_debug = yes mail_location = maildir:/home/vmail/%d/%n/Maildir maildir_very_dirty_syncs = yes mbox_write_locks = fcntl namespace { inbox = yes location = prefix = INBOX. separator = . type = private } namespace inbox { 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.ext driver = sql } postmaster_address = pmatos protocols = imap quota_full_tempfail = yes service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-master { mode = 0600 user = vmail } user = $default_internal_user } ssl = required ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { args = uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes driver = static } protocol lda { auth_socket_path = /var/run/dovecot/auth-master deliver_log_format = msgid=%m: %$ log_path = /home/vmail/dovecot-deliver.log } protocol imap { mail_max_userip_connections = 100 } I started to filter my email with imapfilter running on the same host as dovecot. I would therefore like to deliver email to a folder called PreINBOX so that imapfilter then sorts the email and ends up delivering only the useful email to INBOX. How can I change the name of the inbox dovecot delivers to? Best, -- Paulo Matos

Error: User initialization failed

OK, I obviously forgot something when setting up new user accounts (which I did via postfix admin to add them to the MySQL database): dovecot: lda(chance(a)example.com): Error: User initialization failed: Namespace '': Ambiguous mail location setting, don't know what to do with it: /usr/local/virtual/chance@ example.com (try prefixing it with mbox: or milder:) I have lots of mysql users defined and working, but do I need to manually create the mail store for new ones? (Sorry, it’s been quite a long time since I had to add accounts). -- You start a conversation you can't even finish it You're talkin' a lot, but you're not sayin' anything When I have nothing to say, my lips are sealed Say something once, why say it again?

logging into user mailboxes with admin credentials
by Noam Birnbaum 19 Aug '15

19 Aug '15

Hey folks, We are planning a migration away from Dovecot (sorry) to Google Apps and are trying to figure out how to migrate the contents of user mailboxes to the new provider. Normally we would use an IMAP migration tool to log into each user's mailbox on the old and new providers and transfer the data that way. However, there is no central directory service; all accounts are local. We have a large number of users and for both management and security reasons it's not feasible to compile a list of all IMAP passwords. Is there a way to log into user IMAP accounts on Dovecot using a central administrative credential? Thanks!

NFSv4 delegation
by brd 18 Aug '15

18 Aug '15

hi all, i'm managing a large installation of a dovecot cluster in director + NFS backend architecture and we are moving from NFSv3 to NFSv4. Our NFS server is a Netapp in clustered mode and reading technical specs of NFSv4 delegation feature it seems that enabling delegation in this type of dovecot architecture should bring great benefits: only one backend server access a specific mailbox at a time (even deliveries are managed by director hashing via LMTP) so the getattr rpc calls should decrease significantly while the risk of conflicting delegations is very low (impacting negatively on the benefits obtainable). Can anyone confirm this hypothesis? I've heard that the linux implementation of NFSv4 delegation is mature only for read delegation (and not yet for write delegation): is this true? And, if true, could this fact limit the benefits of activating NFS delegation feature? Best regards -brd

multiple messages per second to a single mailbox
by Chad M Stewart 18 Aug '15

18 Aug '15

Dovecot 2.2.18 on CentOS 6 I have a pair of servers setup with MySQL, Postfix, and Dovecot. Replication is setup and working between the two dovecot instances. The problem I'm running into is that a single mailbox receives a lot of messages, at times the rate is multiple messages per second. Delivery from Postfix to Dovecot is via tcp based LMTP. When I do 'ps -aef|grep lmtp|wc -l' I get 62 and does not appear to go higher than that. At the moment I have 4500 and 8300 messages queued on two Postfix instances waiting to deliver via LMTP to the same dovecot instance. Deliveries only happen via LMTP and only one of the two nodes actually gets the deliveries. What I'm seeing is very high load on the system (40) and queues building on the Postfix side. Replication is keeping up. Looking at the logs now I see anywhere from 4-7 messages per second delivered to this single mailbox. I would like to increase that rate a lot. These machines are VMs hosted on Xenserver 6.x. I have them setup with 8 vCPUs (2 sockets with 4 cores per socket), the dom0 machines have dual HBA connectors back to a SAN and have 128 CPUs and 256GB of RAM and are not taxed. I added a 2nd virtual disk that is used for storing mailbox data. It is ext4 and has noatime set during mount. /var is also mounted with noatime. The performance graphs in XenCenter show nearly all 8 vCPUs at about 50%, and the writes on the mailbox data disk are about 20%. iostat is showing mostly <5 for await times for the disks, though I do see a 10 now and again. I'm guessing that maybe I'm hitting a mailbox locking issue and not sure how to reduce the contention and thereby increase the delivery rate to this mailbox. -Chad

Syncing two mail servers?
by Knute Johnson 17 Aug '15

17 Aug '15

I currently have a mail server using Dovecot and sendmail. I was thinking I would like to have a backup of my mail and an additional server in case of hardware failure. Is it possible to run two identical or nearly identical server setups and sync the mail files between them? If it is possible, in general terms how would one go about this? Thanks, -- Knute Johnson

sieve-filter failure problems
by Jost Krieger 17 Aug '15

17 Aug '15

I use sieve-filter for postprocessing misclassified mail. For false positives I use the following script: require [ "variables", "include", "fileinto" ]; global [ "FORCENOSPAM", "ext", "ext1" ]; set "FORCENOSPAM" "YES"; fileinto "JUNK-PRENOUCE"; if header :matches "Delivered-To" "*+*@*" { set "ext" "${2}"; set "ext1" "${2}"; } include :personal "production"; FORCENOSPAM suppresses the spam handling and the Delivered-To stuff tries to regenerate envelope info. This is my crontab entry: 1-57/4 * * * * cd ~kriegjcb; /usr/local/dovecot/bin/sieve-filter -v -e -W -u kriegjcb -m Spam/U0-failed ~kriegjcb/sieve/nospamfilter.sieve Spam/U0 Most things work fine, but a few of my rules will try to forward mail. This will fail and my idea was I handle this manually from the folder Spam/U0-failed. Unfortunately the mail will arrive there but will also be left in the source folder Spam/U0 and will be processed again every 4 minutes ... This is probably not intentional?

Duplicate mails with pop3 + dsync replication
by Wolfgang Hennerbichler 17 Aug '15

17 Aug '15

Hi, When I enable (and it only happens when it is actually running) replication over TCP my users get duplicate mails via pop3. Here’s what happens: * User gets mail * Mail appears in (Maildir) new/ folder on both replicas * user retrieves mail (retr), calls dele. Mail still exists in new/ folder on both replicas. * user runs retr (and gets the duplicate) and dele a second time, the mail is actually removed. If I disable replication this behaviour goes away. I use dovecot from debian stable resources. Any help would _really_ be appreciated.

sieve and antispam
by Andrew McN 17 Aug '15

17 Aug '15

I have a fairly standard antispam/dspam setup: postfix delivers to dspam, which classifies and tags the mail, and then passes it to postfix which uses sieve to put mail into the appropriate folders based on dspam's classification. I also have the antispam plugin watching mail being moved between folders and re-training dpsam accordingly. If I now add some sieve filter rules which put incoming mail into appropriate folders, possibly overriding what would normally result from dspam's classification, will that be seen by the antispam plugin and used for training dspam?

ipv4 imap not accepting connections in mixed ipv4/ipv6
by djk 15 Aug '15

15 Aug '15

I have two installations of dovecot 2.18, apart from the necessary changes to allow them to replicate amongst themselves the configs are identical. Both are running Ubuntu 14.04 and are kept up to date. One is running 64bit and the other 32 bit (for historical reasons). Both have ipv4 and ipv6 addresses. The 64 bit installation allows access on port 143 and 993 on both ipv4 and ipv6. The 32 bit installation does not allow access on 143 on ipv4, but allows ipv4/ipv6 on 993. Both installations happily allow connections to any other ports that dovecot might be using on both ipv4/ipv6, as well as everything else that is running (on other ports) on those machines. There are firewalls, but no warning messages. Switching firewalls off makes no difference. Tcpdump shows the SYN packets arriving on the (correct) interface. Any suggestions? Dirk

IMAP folder separator issue
by Alex 15 Aug '15

15 Aug '15

Hi, I'm using dovecot-2.2.18 on fedora22 and having a problem with Thunderbird. I reported this problem some time ago, and received some tips, but no solution that's worked. I'm now trying to fix this in earnest, and having problems. The problem is sub-folders are created with a caret in them, instead of a new folder below the parent folder. So instead of folder/sub-folder, folder^sub-folder is created. I'm using mbox folders, and it worked under previous versions of fedora and dovecot. I believe it has to do with the separator character that's used, based on this wiki page: http://wiki2.dovecot.org/Plugins/Listescape The problem is that those instructions cause errors: Aug 14 20:00:01 orion dovecot: pop3(cerberus): Error: User initialization failed: namespace configuration error: Duplicate namespace prefix: "" Aug 14 20:00:01 orion dovecot: pop3(cerberus): Error: Invalid user settings. Refer to server log for more information. I've also had to change the "namespace private" to "namespace { type=private }" as that's apparently a deprecated syntax. Perhaps there's an updated page with more instruction and correct information? I'm unsure where this duplicate namespace is that it's talking about... I've included my doveconf output below, in hopes someone can help. I should also point out that "separator = $" is quoted in the original doveconf.conf but apparently doveconf doesn't properly print it. # 2.2.18: /etc/dovecot/dovecot.conf # OS: Linux 4.0.7-300.fc22.x86_64 x86_64 Fedora release 22 (Twenty Two) default_client_limit = 2000 mail_gid = mail mail_location = mbox:~/mail:INBOX=/var/spool/mail/%u mail_plugins = " listescape" mail_privileged_group = mail mbox_write_locks = fcntl namespace { inbox = yes location = prefix = separator = $ type = private } 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 = pam } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } service imap-login { inet_listener imap { port = 0 } inet_listener imaps { port = 993 } process_min_avail = 20 service_count = 0 } service pop3-login { inet_listener pop3 { port = 0 } inet_listener pop3s { address = 192.168.1.100 port = 995 } } ssl_ca = </etc/pki/dovecot/certs/ca-bundle.pem ssl_cert = </etc/pki/dovecot/certs/orion-2015.pem ssl_key = </etc/pki/dovecot/certs/orion-2015.key userdb { driver = passwd } userdb { driver = passwd }

Grepping for the message-ID in the mail.log, I can see lmtp says it is saved : Aug 12 15:23:23 imap-01 dovecot: lmtp(4943, johndoe(a)example.net) fFuCO09Hy1VPEwAA2t/0+w: sieve: vsize= msgid=<037e01d0d502$0e3687d0$2aa39770$(a)example.net>: stored mail into mailbox 'INBOX' The only difference with others recipients is the 'sieve:... stored mail' instead of 'saved mail to' when there is no sieve. But when he asked me, the message was no more in his maildir (I checked with doveadm search). As we have checked and disabled all the filters in his MUA and on the server (sieve) and this issue still continue, I did mkdir a dovecot.rawlog inside his home. With the help of rawlog, I can see that the message can be found in a .out file (by grepping the Message-ID). And by reading this .out log raw log, the entire message were sent to the client. So I guess that : * the message was written to disk * it was sent to the MUA But I need your help because I don't get how this message disappear from his maildir. My assumptions was that the client must do some commands like : * STORE the \Deleted flag to this message UID * and then, later do EXPUNGE but I did : * grep -i expunge * 20150812* => no match * grep -iE '\+flags .*\\deleted' => a few matches but not with the appropriate UID snippet from the 20150812-133858-13317.in file: 8nk1 UID FETCH 208209 (UID FLAGS RFC822.SIZE BODY.PEEK[HEADER] INTERNALDATE) p7uv IDLE DONE 6yk3 NOOP 83g6 IDLE DONE yhbd UID FETCH 208209 (UID FLAGS BODY.PEEK[]) fy16 IDLE DONE snippet from the 20150812-133858-13317.out file: * 56295 FETCH (UID 208209) wn2p OK Fetch completed. * 56295 FETCH (UID 208209 FLAGS (\Deleted \Seen \Recent) RFC822.SIZE 17138 INTERNALDATE "12-Aug-2015 15:23:22 +0200" BODY[HEADER] {2836} Considering these points: * I cannot find any match with 208209 early in raw logs * I don't see any expunge for the whole day * I've grepped for \Deleted (insensitive) and didn't find matching like a interval of messages UID. What did I miss to find out how/when the message got \Deleted flag and was removed from his maildir? A few about my setup : * system is ubuntu 14.04 inside OpenVZ containers (Proxmox) * dovecot version is 2.2.9 from Ubuntu packages * 2 director with Internet and local ip addresses * 2 backends with only local addresses * these dovecot access storage servers by NFSv3 (that's why we have director) * imap/lmtp are proxied Thanks a lot for reading, I'm really disappointed about this problem. For the moment, I'll delete his script even if all rules are disabled (via roundcube, and I checked the rule is commented in the file). And also I'll try to watch what happens with inotify on the storage server.

backing up IMAP server on a hard drive
by Kevin Laurie 13 Aug '15

13 Aug '15

Hi, I am trying to back up my IMAP server to a hard drive. Later I intend to extract all mails for attachments. What do you reckon is the best too to perform this ? Imapsync or Thunderbird (or something else, please recommend) One problem I am having with imapsync is the setting for host2 (being a localhost computer). How does one set a parameter for host2 being a desktop computer. Thanks Kevin

userdb / user map with director
by Will Yardley 10 Aug '15

10 Aug '15

This is with dovecot-ee 2.2.18.2 on RHEL6.... To handle backend and frontend on same machine, I'm using the following hack, as previously outlined here: [in director instance config] passdb { # See thread ending in: # http://dovecot.org/pipermail/dovecot/2012-June/083817.html # for why this has to be sql instead of 'static' driver = sql args = /etc/dovecot/dovecot-sql.conf } [in /etc/dovecot/dovecot-sql.conf] driver = sqlite connect = /etc/dovecot/empty.db password_query = select 'y' as proxy, \ NULL as password, \ 'y' as nopassword, \ case '%a' \ when '110' then '10110' \ when '995' then '10110' \ when '143' then '10143' \ when '993' then '10143' end \ as port; This works, but I was getting a failure on usernames, since director instance didn't have a userdb. So I tried the following: [in config] passdb { driver = sql args = /etc/dovecot/dovecot-sql.conf } userdb { driver = prefetch } and appended the following to the SQL query: password_query = select '%u' AS user, \ Then I see the following error in the log when I try to run the map "Trying to iterate users, but userdbs don't support it" and doveadm -i director director map returns: Error: User listing returned failure Error: user listing failed [...] I'm sure I'm missing something obvious, so is there an easy fix to make this mapping work? w

Dovecot sends "OK Logged in" with empty tag
by Simon Thelen 10 Aug '15

10 Aug '15

Hello, I'm currently writing my own IMAP client and testing it against Dovecot, and when doing PLAIN AUTH Dovecot sends the "OK Logged in" with an empty tag at the start. I tried reproducing the conversation with netcat, but Dovecot sends a correctly tagged OK at the end of the AUTH so I assume it's timing related. I've attached pcap dumps of the TCP conversation in both situations as well as the output of dovecot -n. Side Note: Why does Dovecot send the updated capabilities before OK'ing the authentication? Seems strange to me as the client can't assume that the authentication proceeded successfully until it actually receives the OK so it has to assume that those capabilities are pre login. -- Simon Thelen

Using a separate passdb per service
by Gerry 10 Aug '15

10 Aug '15

Situation: one front-facing server running Dovecot as IMAP/POP3/ ManageSieve proxy, a mixture of IMAP servers (Dovecot, Exchange, ...) in the back-end. Dovecot's passdb does lookups against MySQL which contains a simple user/host mapping, the actual authentication happens on the back-end IMAP servers. The configuration is more or less as described here: http://wiki2.dovecot.org/PasswordDatabase/ExtraFields/Proxy Now I would like to add a Postfix instance on the front-facing server which listens on the submission port and authenticates users via SASL using the local Dovecot's UNIX socket. The idea being that a user only needs to remember one single hostname, one username and one password for all mail-related services. The problem is that Dovecot is operating in proxy mode, which means that the password_query returns NULL as the password and explicitly returns a field "nopasswd" containing "Y". Thus, users can not authenticate against the UNIX socket. What I think I want to do is convince Dovecot to use one passdb for the imap/pop3/managesieve services and different one for the "auth" service. The configuration snippet below doesn't work, but it should illustrate what I want to achieve: > protocols = imap pop3 sieve > > service auth { > passdb sql { > driver = sql > args = /etc/dovecot/mysql-auth-sasl.conf.ext > } > > unix_listener /var/spool/postfix/private/auth { > user = postfix > group = postfix > mode = 0666 > } > } > > # IMAP/POP3/ManageSieve auth against MySQL > passdb sql { > driver = sql > args = /etc/dovecot/mysql-auth-default.conf.ext > } Example mysql-auth-sasl.conf.ext > driver = mysql > connect = host=127.0.0.1 dbname=mail user=mail password=somethingrandom > password_query = SELECT password AS password FROM users WHERE login = '%u' Example mysql-auth-default.conf.ext: > driver = mysql > connect = host=127.0.0.1 dbname=mail user=mail password=somethingrandom > password_query = SELECT NULL AS password, 'Y' as nopassword, host, 'Y' AS proxy FROM users WHERE login = '%u' Any pointers?

Trying to back

Hi, I am trying to backup multiple mail accounts by using imapsync and Dovecot on my local machine. I am using maildir as a mail storage format and currently have the following setting on my local machine :- mail_location = maildir:~/Maildir I am afraid that if I imapsync multiple accounts they will all get stored in the same location. Is there a way to seperate the accounts based on the email address? Appreciate if someone could advise. Thanks! Kevin

Dovecot/Pigeonhole Issue (UTC modtime instead of localtime)
by Christoph Gröver 06 Aug '15

06 Aug '15

Hi List, We are using the following setup: Dovecot-2.2.18 Pigeonhole-0.4.8 (for Dovecot-2.2) After the mail is finally delivered via a fileinto by the Sieve filter it gets an updated timestamp (modification time). The server has localtime setup correctly IMO (UTC +0200), but still the delivered mail is setup as being two hours old. I think I found out that the function sieve_file_storage_update_mtime() is the cause of this problem. But perhaps there has to be some kind of setup, that tells pigeonhole to use the 2 hour offset of CEST. I think to reset the mtime by utime(s) is a bit strange. It already gets the correct modtime just by storing it in the filesystem. Last version we used (0.2.5) did not have this poblem. So it must be there for some reason? Perhaps you can enlighten me. Thanks for your time.

Renaming shared mailbox makes it disappear from sharee
by Andy Csillag 03 Aug '15

03 Aug '15

I've run into an interesting thing. If a mailbox has been shared to a second user (I'll call it the sharee), and there are subfolders on that mailbox, and the sharee renames one of those subfolders, it disappears from view to the sharee. The only way I've been able discover to fix it is to have the sharee create a new subfolder -- then the renamed folder shows up again; in addition to the newly created folder. For example, first(a)example.org shares it's INBOX to second(a)example.org. There's a folder INBOX/thing, which second@ renames to INBOX/renamed (ACLs permitting). second@ can no longer can see INBOX/renamed (or INBOX/thing for that matter), via IMAP's LIST command. But if second@ creates a new folder INBOX/other, INBOX/renamed is now visible. This is very reproducible for me. I also tried it without the imappostlogin bit (in the dovecot -n). Anyone else run into this? No NFS is involved, this is a single machine setup.

Structure of dovecot.index.pvt.log

Hi, we are migrating from Cyrus to Dovecot and I would like to migrate seen flags for shared folder too. We have Dovecot 2.2.13 prepared as: location = maildir:/vmail/user/%%n/Maildir:INDEXPVT=/vmail/user/%n/Maildir/Shared/%%n Now I'm looking for 'dovecot.index.pvt.log' syntax to be able migrate Seen flags. All I know is, that index contains messages UID and Seen flag. May I ask you for a link to doc (if it exists) or into a source code? Should I care about 'dovecot.index.pvt.log' timestamps?

Question RE listescape and separators
by Jakob Curdes 30 Jul '15

30 Jul '15

Hello, we just start moving a large number of mailboxes to a new dovecot server with dovecot 2.0.9 (from CentOS) and sdbox as mailbox type. We use imapsync so there is no issue with mailbox type conversion. However, in test runs I noted that some mail folders,e.g. with dots in them, could not be transferred; dovecot says Couldn't create folder [7.8) Personnel] from [7.8) Personnel]: 106 NO Character not allowed in mailbox name: '.' We have the separator "/" defined for our only namespace so the dot should not be an issue!? I tried to use listescape but either the plugin is not loading (how can I verify this?) or it does not escape the dot in the mailbox name. The listescape settings are the defaults: namespace { separator = / (...) } mail_plugins = $mail_plugins listescape plugin { listescape_char = "\\" } What am I doing wrong? How can I make dots in mailboxes possible? Best regards, Jakob Curdes

Re: Sieve case insensitive detail part

Hello Sascha, sieve scripts are quite easy, see Steffen's example. I think what you want your script to do is: With any detail part, lowercase it, file message into detail folder, create as necessary. Something like auto-variables in Makfiles, where the rule gets its value from the target, e.g. -- peter

Deafness
by Steffan Cline 29 Jul '15

29 Jul '15

I’ve started in the last day or so having issues where users get a timeout when connecting to dovecot. The iPhone interprets this as an auth issue but re-entering the password makes no change. Outlook will either just not connect to it at all or it gives an error to re-enter the password also with no change. This happens within an hour of a "service dovecot restart". I’m using CentOS 6 with dovecot 2.0.9 from the centos repos. There’s nothing visible in the logs. Suggestions of what to check for? Thanks, Steffan

dbox: message internal date
by Francesco 29 Jul '15

29 Jul '15

Hello everyone and thanks in advance for the help :) I'm trying to figure out where does dovecot store the message internal date when using single dbox storage format. In Maildir format, the internal date is determined by the actual date of the file on the filesystem, but in dbox it doesn't seem to be the case. I'm looking forward for a way to modify a message internal date when on a dovecot instance running dbox storage engine, maybe anyone knows if it's possible and how to accomplish this? Again, thank you for the help Sincerely Francesco

sharing INBOX with ACL -> share all folders

Importing mbox archives into a inbox?

Greetings from a dovecot newbie. I have a bunch of mailing list archives (in mbox) format that I want to dump into the inbox for a particular account on the system. I want them to retain all of their information, particularly the date. I'm not seeing how to do this, but I could be missing it. Is this LDA or LMTP with some command-line options I'm not seeing? --Paul Hoffman

POP3 getting previously delivered messages.
by Jas Reehal 24 Jul '15

24 Jul '15

Hi All, This is my first post to this list. I have recently upgraded to dovecot version 2.2.10. 1. I have one POP3 user who does not want to delete his email on the server. 2. He has accumulated over 19000 messages, and the 'dovecot.uidlist' file has more than 19000 lines! 3. Occasionally now when he has received one or more new emails, and his email client does a 'get new mail' operation (POP3) he begins to receive email he has already received previously. last time this happened all 19000+ messages were delivered again, leaning to duplicate entries in all his mailboxes. I have reproduced this issue with a dummy email account with a POP3 client, leaving all messages on the server. I have delivered 20000 messages to this email account, each about 1.3k ins size and each with .... Subject: Message number <n> Body containing "Message number <n>" where <n> is 1 to 20000 now occasionally if I send another message to this email account, and then check for new messages using a POP3 client I get more messages downloaded than I expect! The 'dovecot.uidlist' file is not corrupt, but I beleive due ti it's size (number of lines) the is an issue on compiling a ' POP3 drop-list'. I have attached a file 'dovecot-a.txt' which shows the 'dovecot -a' output from my server. Based on what I have investigated I believe that this issue may not be correlated with a migration to version 2.2.10, but more to do with the number of messages retained on the server. Is there anyone who has any insight into what is happening and if there is any remedy, perhaps a "pop3_client_workarounds =" or other POP3 or UIDL directive in the conf files? The user is stubbornly resisting migration to IMAP, because of the time and effort he says will be required to replicate his organised filing/storage of messages on the server.

possible patch for ACL SQL ERROR: duplicate key value violates unique constraint "user_shares_pkey"
by Steffen Kaiser 24 Jul '15

24 Jul '15

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I'm using Postgres as dict backend now and then I get this error, when someone changed ACLs, actually for some reason some users, who get permission from other users, get this error quite often: dict: Error: sql dict: commit failed: ERROR: duplicate key value violates unique constraint "user_shares_pkey" (query: INSERT INTO user_shares (dummy,to_user,from_user) VALUES ('1','user1','user2')) It looks like that this error is triggered, when a MUA is connecting to Dovecot after ACLs had been changed and opens several mailboxes at once. So two or parallel Dovecot instances try to insert the record simultaneously. With a similiar technique to the quota problem, I added a trigger. The idea is to use the condition dummy ISNULL to detect, that the function was triggered from the INSERT of the function itself, hence, breaking the recursive triggers. This assumes that dummy is never NULL from Dovecot. The same applies to anyone_shares, just remove the to_user field from the function. Does somebody see something wrong with my hack? ============= CREATE FUNCTION insert_sharing() RETURNS trigger LANGUAGE plpgsql AS $$ BEGIN IF NEW.dummy IS NULL THEN -- ugly kludge: we came here from this function, really do try to insert return NEW; END IF; LOOP UPDATE user_shares SET dummy = NEW.dummy WHERE from_user = NEW.from_user AND to_user = NEW.to_user; IF found THEN -- updated and inserted RETURN NULL; END IF; BEGIN INSERT INTO user_shares (from_user,to_user,dummy) VALUES (NEW.from_user,NEW.to_user,NULL); --- return NULL; EXCEPTION WHEN unique_violation THEN -- someone just inserted the record, update it END; -- Update dummy after INSERT END LOOP; END; $$; CREATE TRIGGER insertsharing BEFORE INSERT ON user_shares FOR EACH ROW EXECUTE PROCEDURE insert_sharing(); - -- Steffen Kaiser -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEVAwUBVbHxJXz1H7kL/d9rAQIn5gf/dNMQKmmigGrbccGQQrsGU66B6OHvTY7L 1vyh8hgr985KNk2/Ws/usLnAqpl5jhpo8kVPLI8TqcGYLAS/67TOIFrwLKAEBU96 e+QpbqqiSm66mZwWOQZgCI63+Fh7fdBUMREL6UqGleFF1GrzNnjmX4MGecbpu/L9 gQMAGUG++/S+ka9S6B275RXIj9DvWzq/oYqJ1M1grGckUxXfDk5szLyvuIJ981At 20qaCHEIlIOlkQ0ttE4W+RWkkYS2rMJvCzQelF4pcm6vaxhXxvqUryzmy9pv+UUT osqS6igWt7BPXF7ku8+rKYVp/qPZrh9IWXMsajr/2nI+V5gRb6u2ow== =gb1P -----END PGP SIGNATURE-----

Authenticate system user with alternate password
by AC 23 Jul '15

23 Jul '15

Is there a way to configure Dovecot to authenticate a system user against a different password list? I want to give my own personal account on my machine a password for IMAP and have that be different from the password I use to log into the system for maintenance purposes. I currently do this for outbound email by having the MTA authenticate against a SASL database during the initial SMTP connection (STARTTLS).

dovecot proxy/director and high availability design
by Chad M Stewart 21 Jul '15

21 Jul '15

I'm trying to determine which dovecot components to use and how to order them in the network path from client to mail store. If I have say 1,000 users, all stored in MySQL (or LDAP) and have 4 mail stores, configured into 2, 2 node pods. MS1 and MS2 are pod1 and are configured with replication (dsync) and host users 0-500. MS3 and MS4 are pod2 and are configured with replication between them and host users 501-1000. Ideally the active connections in pod1 would be split 50/50 between MS1 and MS2. When maintenance is performed obviously all active connections/users would be moved to the other node in the pod and then rebalanced once maintenance is completed. I'm not sure if I need to use both the proxy and director, or just one or the other? If both then what is the proper path, from a network perspective? I like the functionality director provides, being able to add/remove servers on the fly and adjust connections, etc.. But from what I've read director needs to know about all mail servers. The problem is that not all servers host all users. User100 could be serviced by ms1 or ms2, but not by ms3 or ms4. I'm trying to design a system that should provide as close to 99.999% service availability as possible. Thank you, Chad

Dovecot in UCS
by Daniel Tröder 21 Jul '15

21 Jul '15

Hello :) I hope you can forgive me a little advertisement: The English translation of my blog post on the Dovecot integration I did for the Univention Corporate Server (UCS) is online: https://www.univention.com/2015/07/dovecot-is-the-default-imappop3-mail-ser… UCS is a Debian based Linux Distribution, everything - incl. management bits - is OSS. There is a "Core Edition" that you can download and use (also commercially) for free, that is - despite its name - feature complete: https://www.univention.com/downloads/ucs-download A lot of interesting Dovecot features can be changed without breaking things, so this blog post may be interesting to everyone. The German version can be found here: https://www.univention.de/2015/07/mailserver-dovecot-als-standard-imappop3-… Greetings Daniel Tröder

[Dovecot Antispam] Can't seem to load plugin
by James Lott 21 Jul '15

21 Jul '15

Hello list, I'm hoping there is a user of the antispam plugin out there who might be able to lend a pointer or two. I am running dovecot 2.2.18 on FreeBSD 10 (doveconf -n attached), where I have installed the binary dovecot2-antispam-plugin package. I have put together what should, in my estimation, be a working configuration for the plugin. I have reviewed the man page and the online documentation, and I think at the *very least* I should be seeing errors for something not working correctly. However, what I have is a great deal more troubling. There is no sign on the plugin even attempting to load. No log entries, no errors, nothing. The plugin is definitely in the right place with the right name, since I let the package manager handle all of that for me root@zerolag:~ # ls -l /usr/local/lib/dovecot/lib90_antispam_plugin.so -rwxr-xr-x 1 root wheel 32488 Jul 2 09:41 /usr/local/lib/dovecot/lib90_antispam_plugin.so I am unable to make any sense of this. Thanks in advance for any pointers :) -- James Lott

Problems with IMAP/POP and dovecot director on backend (director_proxy_maybe)
by dominik 20 Jul '15

20 Jul '15

Hello dovecot community, first of all: dovecot ist great! ;) ...nevertheless I´ve got some problems to get my director scenario running as needed/expected :( My scenario: I´d like to configure two dovecot backends, without the need for multiple dovecot instances. Both backend servers are active/active and act on top of a glusterfs storage, which implies the need for dovecot director. As described in release notes (v2.2.17) this should be possible by setting the extra field "director_proxy_maybe=yes".: "+ director: Implemented director_proxy_maybe passdb extra field to be able to run director and backend in the same Dovecot instance. (LMTP doesn't support mixed proxy/non-proxy destinations currently.)" My setup: * 1 LMTP client (SLES11p3 with postfix) * 1 IMAP/POP3 client (Debian8 with thunderbird 31.6.0): 10.0.0.26. The client connects through a dovecot mailproxy or direct. * 1 dovecot mailproxy: 10.0.1.151 * 2 mailbox backends running dovecot v2.2.18 on SLES11p3 with mail_location pointing to a glusterfs-mountpoint (GlusterFS: v3.6.3) * mailbox01.example.de: 10.0.2.21 * mailbox02.example.de: 10.0.2.22 * mailbox-gluster.example.de points as an A-RR to 10.0.2.21 and 10.0.2.22. My problem: With LMTP everything works fine (thanks for this!). The director sets the "host" field correctly and all delivery attempts work fine to the estimated backend servers. But when I try to connect via IMAP-/POP3-client (through proxy or direct) it fails with following log messages. It seems, that the director doesn´t set the host field within IMAP/POP sessions before proxying!? auth: Debug: auth client connected (pid=46359) imap-login: ID sent: x-session-id=V3iJmU4biAAK/BAa, x-originating-ip=10.0.0.26, x-originating-port=54408, x-connected-ip=10.0.1.151, x-connected-port=143, x-proxy-ttl=4: user=<>, rip=10.0.1.151, lip=10.0.2.21, session=<RVnAm04bzwAK/FCX> auth: Debug: client in: AUTH 1 PLAIN service=imap session=RVnAm04bzwAK/FCX lip=10.0.2.21 rip=10.0.1.151 lport=143 rport=54735 resp=<hidden> auth: Debug: ldap(tester(a)example.de,10.0.1.151,<RVnAm04bzwAK/FCX>): bind search: base=o=example,c=de filter=(&(|(uid=tester@example.de)(mail=tester@example.de))(!(<cut-cut-cut>)) [...] auth: Debug: client passdb out: OK 1 user=tester(a)example.de director_proxy_maybe=yes lip=10.0.2.21 lport=143 proxy pass=<hidden> imap-login: Debug: Ignoring unknown passdb extra field: director_proxy_maybe imap-login: Debug: Ignoring unknown passdb extra field: lip imap-login: Debug: Ignoring unknown passdb extra field: lport imap-login: Error: proxy: host not given: user=<tester(a)example.de>, method=PLAIN, rip=10.0.2.151, lip=10.0.2.21, session=<RVnAm04bzwAK/FCX> imap-login: Disconnected (internal failure, 1 successful auths): user=<tester(a)example.de>, method=PLAIN, rip=10.0.2.151, lip=10.0.2.21, session=<RVnAm04bzwAK/FCX> Finally the output of "doveadm proxy list" is empty! "doveadm director map" output after a successfull LMTP delivery attempt (before: doveadm director flush all): user hash mail server ip expire time tester(a)example.de 856838019 10.0.2.21 2015-07-20 15:49:18 "doveadm director map" output after a failed IMAP session attempt (before: doveadm director flush all): user hash mail server ip expire time tester(a)example.de 856838019 10.0.2.21 2015-07-20 15:50:02 So, director seems to work in this constellation, but only for LMTP and not for IMAP/POP Proxy :( Has anybody configured this before?

Helper to open "/doc/wiki/.." paths; suggestions
by Christian Jaeger 18 Jul '15

18 Jul '15

I wrote this script to have an easier time looking at the doc paths referenced from the default configuration files (currently using dovecot in Debian oldstable). Feel free to include in the distribution or wherever. Probably a better solution would be to publish the config files with the paths already expanded to the online URL, or a local filesystem path that works (in the latter case, I'd wish the docs would be bundled in html format). I wonder whether to approach the debian maintainer about this or the Dovecot team? Definitely something for the maintainer is to put the bundled docs in a place where I would have expected it (/usr/share/docs/dovecot/wiki/ instead of /usr/share/docs/dovecot-core/dovecot/wiki/, or a dovecot-doc package, also, links or mentions from the doc dirs of all dovecot packages to the docs). Also, I think there should be a README document that serves as the first introduction of the user to how to configure the system: how are the config files split up, what does "!include" mean (why the "!"? Is it a comment char?), other rules on the config file format. I.e. the basics to enable the new user to go about reading the current config and where to find further docs/help. Thanks & Cheers, Christian.

Getting duplicated mails while using imapc and dsync
by Michael 17 Jul '15

17 Jul '15

Hello list, currently I'm migrating our old mailserver to a new mail architecture that is based on a master-master dovecot setup (two machines). The replication actually works but I'm also syncing our mails from the current mailserver via imapc on a regular schedule. For some reason I've in most (but not all) imapc-synced mailboxes duplicated emails that I also can't deduplicate with doveadm. I've also set up test-mailboxes that I don't sync with imapc and in those I don't have any duplicated mails. My command to sync the mails from the old host to the master-master system looks as follows: doveadm -o imapc_user=$i*dovemig -o imapc_password=<password> -o imapc_host=<oldhost> -o imapc_features="rfc822.size fetch-headers" -o mail_prefetch_count=20 -v -D sync -R -u$EMAIL imapc: &> $LOGS/$i.log So, is this actually the wrong approach to sync mails from the old host to the new one or is it just not recommended to sync them over-and-over again in such a setup via imapc or is it better to sync them only once? Any hint/pointing me to the right solution is greatly appreciated. Michael

Dovecot-EE repository for Debian 8 (Jessie/stable)
by Bernhard Schmidt 17 Jul '15

17 Jul '15

Hi, are there plans to support Debian 8 (alias stable, alias jessie) in the dovecot-ee repository? Currently there are only squeeze and wheezy repos. The wheezy repo is uninstallable due to an unsatisfyable dependency on libicu48. Of course you can install libicu48 from Wheezy on a Jessie system, but this will break security updates and might not be the best idea for a library like that. Bernhard

Quota policy service not rejecting messages when user over quota
by james＠lottspot.com 17 Jul '15

17 Jul '15

For some very odd reason, the quota-status service is failing to enforce quotas. Every other aspect of my configuration is working with absolutely no problems. When I attempt delivery via LTMP, the message is, as expected, rejected due to the user's inbox being full. root@smtp:/usr/local/etc/mail-config # nc -U /var/spool/postfix/private/dovecot-lmtp < 220 mx0.lottspot.com Dovecot ready. > LHLO localhost < 250-mx0.lottspot.com < 250-8BITMIME < 250-ENHANCEDSTATUSCODES < 250 PIPELINING > MAIL FROM:<root@localhost> < 250 2.1.0 OK > RCPT TO:<james(a)lottspot.vpn> < 552 5.2.2 <james(a)lottspot.vpn> Quota exceeded (mailbox for user is full) The policy service however, just lets everything go right through. I know that accessing the userdb is not an issue, because I passed a bogus user before passing my real user and received the expected response. root@smtp:/usr/local/etc/mail-config # nc -U /var/spool/postfix/private/policy-quota > recipient=noop(a)fake.tld > < action=551 User not found < > recipient=james(a)lottspot.vpn > < action=250 Quota status success < I'm using Dovecot 2.2.15, and I have included my quota configuration below. If anyone wants to see full doveconf -n output, I can provide it, but figured it was a bit much for this case. Thanks in advance for any pointers! --> Note: I'm the quota_status_* directives have been set as is for testing purposes only. I'm fully aware not to do that in production. plugin { quota = maildir:User quota quota_rule = *:bytes=1G quota_rule2 = Trash:storage=+10%% quota_status_success = "250 Quota status success" quota_status_nouser = "551 User not found" quota_status_overquota = "552 5.2.2 Recipient mailbox is full" } service quota-status { executable = quota-status -p postfix unix_listener /var/spool/postfix/private/policy-quota { user = postfix group = wheel mode = 0666 } }

[Sieve] Unable to fileinto subfolders
by james＠lottspot.com 17 Jul '15

17 Jul '15

Hello again list! I am configuring a server running Dovecot 2.2.15 (Pigeonhole 0.4.6), and I am having an issue with Sieve scripts where I cannot sort messages into a subfolder of a mailbox. An email which is matched by the following script: require "fileinto"; if header :contains "Subject" "[SORT ME]" { fileinto "INBOX.Sorted"; } Yields the following error: Jul 16 18:54:46 smtp dovecot: lmtp(james(a)lottspot.vpn): Error: DiJmNGZgqFWLFAEANWXNPw: sieve: msgid=<4973528.yvy4Yu8Tt4@arch_project>: failed to store into mailbox 'INBOX.Sorted': Character not allowed in mailbox name: '.' As far as I can tell based on the Sieve usage page in the wiki (http://wiki2.dovecot.org/Pigeonhole/Sieve/Usage) this is *supposed* to work. I have included my namespace configuration below, but if anyone wants the whole doveconf -n, I will gladly provide it. Thanks in advance for any help! namespace inbox { type = private separator = / prefix = inbox = yes mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Spam { auto = subscribe special_use = \Junk } mailbox Trash { auto = subscribe special_use = \Trash } } namespace { type = shared separator = / prefix = shared/%%d/%%n/ location = maildir:/home/%%d/%%n/mail:INDEX=~/indexes/%%d/%%n:INDEXPVT=~/indexes/%%d/%%n subscriptions = no list = children }

question on Dovecot replication
by Arnold Wang 17 Jul '15

17 Jul '15

I'm running Dovecot 2.2.x and have a question on its replication capability. I plan to run Dovecot in two different sites with two nodes at each site. My question is how many replication partners can each Dovecot node have? Can I define three "mail_replica" entries in every node so any message received by one node will be replicated to three other nodes automatically? Thanks in advance for your help.

Admin access to sieve filters with managesieve
by Christian Theune 15 Jul '15

15 Jul '15

Hi, I’ve been a long-time user of Cyrus and started using sieve with Dovecot recently. A question that came up is: how do I access a users’s sieve scripts through managesieve without their credentials? Managesieve allows separating authentation and the corresponding mailbox identification, right? That’s what I used with cyrus sieve all the time. :) I didn’t find documentation in the wiki or googling where to configure someone as admin in Dovecot so he can access foreign sieve scripts through managesieve. Pointers? Am I using the right words?

doveadm search -A problem with dropped privileges
by Sebastian Kricner 14 Jul '15

14 Jul '15

Hello, if you want to answer to this mail, please send it directly to me. I have found a big issue with the following command "doveadm -search -A". It whatsoever works by setting doveadm_worker_count = 0 in the dovecot.conf configuration file. The problem is that doveadm-server or something similar uses privileges of "nobody" and so it fails searching e-mails. Instead also the process tries to create a maildir for "nobody": Debug: Namespace : /var/mail/nobody doesn't exist yet, using default permissions Debug: Namespace : Using permissions from /var/mail/nobody: mode=0700 gid=default Error: User initialization failed: Namespace '': mkdir(/var/mail/nobody) failed: Permission denied (euid=65534(nobody) egid=65534(nobody) missing +w perm: /var/mail, we're not in group 12(mail), dir owned by 0:12 mode=0775) Error: search: User init failed Error: userdb lookup: connect(/var/run/dovecot//auth-userdb) failed: Permission denied (euid=65534(nobody) egid=65534(nobody) missing +r perm: /var/run/dovecot//auth-userdb, we're not in group 12(mail), dir owned by 0:0 mode=0755) Error: search: User lookup failed: Internal error occurred. Refer to server log for more information. Even after setting permissions, so that the process can create a maildir for "nobody" in the /var/mail location, it fails to "setresgid" to the particular user to be scanned. It can´t work because it is not possible to gain other user privileges from another user. # 2.2.16: /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.7 # OS: Linux Gentoo Base System release 2.2 auth_cache_negative_ttl = xx mins auth_cache_size = xx M auth_cache_ttl = xx mins auth_mechanisms = xx xx auth_worker_max_count = xx base_dir = /var/run/dovecot/ default_process_limit = xx dict { expire = sqlite:/xx } doveadm_worker_count = 1 first_valid_gid = xx first_valid_uid = xx login_greeting = xx.xx mail_location = maildir:/xx/xx/%u mail_privileged_group = xx 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 index ihave duplicate passdb { args = scheme=SHA512 /xx/xx/xx.xx driver = passwd-file } plugin { expire = xx expire2 = xx expire_dict = proxy::expire sieve = ~/.xx.xx sieve_dir = ~/.xx } protocols = imap sieve service auth { unix_listener auth-client { group = xx mode = 0660 } unix_listener auth-userdb { group = xx mode = 0660 } } service dict { unix_listener dict { mode = 0666 } } service imap-login { inet_listener imap { port = 0 } process_limit = 6 service_count = 1 } ssl_cert = </xx/xx/xx/xx.xx.xx ssl_key = </xx/xx/xx/xx.xx.xx ssl_parameters_regenerate = xx days userdb { driver = passwd } protocol lda { mail_plugins = sieve expire } protocol imap { imap_idle_notify_interval = xx mins mail_max_userip_connections = xx mail_plugins = expire } Regards Sebastian Kricner -- http://tuxwave.net -- the difference to think makes it real!

Systemd and listen restriction to localhost not enforced

Hi, in /etc/dovecot/conf.d/10-master.conf I have restricted IMAP to localhost only: service imap-login { inet_listener imap { address = 127.0.0.1 #port = 143 } inet_listener imaps { #port = 993 #ssl = yes } } However, /lib/systemd/system/dovecot.socket make it listen on 0.0.0.0:143 and [::]:143 causing the service being available to the public which it should not. - IMHO this is a security issue. PS: When starting dovecot I got: Jul 6 22:52:14 srv1 dovecot[19921]: Error: systemd listens on port 143, but it's not configured in Dovecot. Closing.

Hello, dovecot 2.2.18 on CentOS6.5 Jul 08 11:53:44 dsync-server(system): Fatal: master: service(doveadm): child 32554 returned error 83 (Out of memory (service doveadm { vsz_limit=521 MB }, you may need to increase it) - set CORE_OUTOFMEM=1 environment to get core dump) I tried increasing to 1 G, 1024 M or even disabling via value of zero -- to no change. Every other service has the famous 18446744073709551615 B limit. default_vsz_limit = 2 G The second node with the same setup/config is happily accepting a higher value, since both come from the same provisioning I cannot see (or expect) differences around ulimit and thelike. The configuration comes from a single file, so no include drama or such. Any pointers why the setting is being ignored?

ESEARCH multiple folders
by Peter Chiochetti 08 Jul '15

08 Jul '15

FTS-Solr is blazingly fast; yet searching e.g. an archive with subfolders still is slow; I learned, that this is a feature/bug of the imap protocol. So I'd like to ask: Does or will dovecot support the "IMAP4 Multimailbox SEARCH Extension" specified in RFC 7377? -- Kind regards Peter

Scalability with high density servers and proxies, TCP port limits
by Christian Balzer 08 Jul '15

08 Jul '15

Hello, first post in 3 years, kinda shows how painless Dovecot is. ^o^ Also this isn't really a dovecot issue, alas it's involved and since there are some large scale implementations of it I hope somebody here has some insights I might have missed. Currently we're running this setup: 1. LVS (DR mode) in a HA configuration (2 node cluster) 2. Dovecot in proxy mode on a 2 node cluster 3. Dovecot on actual mailbox servers (dual node DRBD clusters) There are about 500k users, but most of them use POP3, so there are usually less than 6k IMAP sesions at any given time. This is about to change, I'm looking at potentially millions of users who will have all semi-permanent IMAP sessions. We already have a pure SSD based mailbox cluster and based on the experiences with that another one is on order that will be able to easily handle about 500k users with regards to IOPS and other needs. However there's the issue of having all these concurrent IMAP sessions. Namely, running out of ephemeral ports. Lets assume 2 million users and 50k ports per IP and revisit the setup above. 1. LVS should have no problem, from experience and tests I expect a well tuned and spec'ed machine to handle millions of connections. This is in DR mode, in NAT mode I assume things would run into a wall a lot quicker. But even if LVS should run out of steam, there's a wide selection of high capacity load balancers available. 2. Here is where the fun starts. Each IMAP session that gets proxied to the real mailbox server needs a port for the outgoing connection. So to support 2 million sessions we need 40 IP addresses here. Ouch. And from a brief test having multiple IP addresses per server won't help either (Dovecot unsurprisingly picks the main IP when establishing a proxy session to the real mailbox), at least not with just one default GW. 3. All of this gets repeated on the actual mailbox servers, by either having a lot of low density servers or (preferably) high density servers with multiple IP addresses. Am I on track so far or missing something obvious? How many concurrent connections do you (hello Timo) think dovecot in proxy mode can handle? High performance mode of course in this case. I'm interested in internal limitations, assume that CPU and RAM are amply supplied. Any and all feedback is appreciated.

HELP: wrinting dovecot-sql.conf to authenticate to an existing database
by Filippo Zeus 08 Jul '15

08 Jul '15

hi all, can anyone help me with dovecot-sql.conf please ? I'm not a mysql expert and I'am trying to authenticate dovecot2 to an existing database. I have a database "egroupware" with table "egw_accounts". The field "account_lid" is the full email address and "account_pwd" is the password in Blowfish format. Here is my dovecot-sql.conf driver = mysql connect = host=localhost dbname=egroupware user=egroupware password=********* default_pass_scheme = BLF-CRYPT password_query = SELECT account_pwd AS password FROM egw_accounts WHERE account_lid = '%u' when I try to login to POP or IMAP I got this error in mail.log/mail.info Error: sql(hidden@mydomain.com,::1): Invalid password in passdb: crypt() failed: Invalid argument auth: Debug: client passdb out: FAIL#0111#011user=hidden(a)mydomain.com dovecot: pop3-login: Debug: Ignoring unknown passdb extra field: I think I'm having trouble with the password value that is stored in the account_pwd as: {crypt}$2a$12$XTAolzXgwMC211MuZELQUedPv9tjZNs7Osh97PnZ50pAKuk3WPGmS Reading at http://wiki2.dovecot.org/Authentication/PasswordSchemes I suppose that the heading "{crypt}$2a$" instead of a simple "$2a$" (witch identifies a Blowfish password) is my problem.

Autocreate folders with specific permissions
by Fabio S. Schmidt 07 Jul '15

07 Jul '15

Hi, I have Dovecot 2.1 deployed running about 65k mailboxes. We need to create a specific folder for all users with specific permissions. I mean, the user could not delete or rename the folder. To create the folder automatically I have used the autocreate, but is there any way to set specific permissions on those folders? My best regards.

Problem with IMAP-Proxy and M$ Exchange-Server
by Luca Bertoncello 07 Jul '15

07 Jul '15

Hi List! I **HATE** Exchange-Server. I think it's not able to manage E-Mails, but we have to use it at work... Well, we need to read the E-Mails from outside, so I configured Dovecot with IMAPC to connect to the Exchange-Server. It works, but I have a problem... If I receive an E-Mail, and I read it from my phone (for example), I see in Outlook that the E-Mail as been read. If I move the E-Mail in another folder from my phone, I see in Outlook the E-Mail in the new folder **AND** in the INBOX. If I check my E-Mail from another phone (or Mail-Client), I see the E-Mail just in the new folder, so I think, the Exchange-Server did move it. But Outlook does not get this information... Any idea how can I solve my problem? Thanks Luca Bertoncello (lucabert(a)lucabert.de)

Large jumps in dovecot-uidlist
by Mark 07 Jul '15

07 Jul '15

Since upgrading to Debian Wheezy I have been observing large jumps in the value stored in dovecot-uidlist. The effect of these jumps is to confuse some mail clients (Thunderbird, Opera Mail) causing them not to display messages from a (random?) point in time onwards in the affected folder. I have been unable to determine the root cause of these jumps. What I do know: 1. I never observed the problem while running Debian Squeeze. 2. The only way I have found to fix the issue is to remove all the dovecot* files from the affected folder and restart dovecot. I have tried removing various subsets of the dovecot* files but haven't yet found a subset that works. 3. I first tried upgrading from Squeeze to Wheezy within a few weeks of the Wheezy release. At that point the problem occurred so frequently that I couldn't sync my mail client with my mail box. Multiple folders exhibited this problem and while I was fixing them the problem appeared in other folders. I was unable to reach a point where the system was stable so I reverted back to Squeeze. 4. Some time later (I think a year but I am not sure) I tried the upgrade to Wheezy again. This time the system was stable. After a few days I noticed that the problem was still occurring but less frequently. Since then I have been fixing the problem as I notice it and experimenting with various settings (mainly locking related) without success. I now have a cron job that looks for problematic folders and fixes them when found. 5. I have updated Dovecot packages to those from Jessie via wheezy-backports and the problem still occurs. 6. Dovecot is installed along with postfix, amavisd-new, clamav-daemon, procmail and fetchmail. 7. The mail server is running on a eSATA SheevaPlug that boots of an external USB drive. All user home dirs (and associated mailboxes) are located on a LUKS/ext3 encrypted partition. 8. The output of dovecot -n may be found at the end of this mail. 9. Uid values for the three most recent instances of this problem are: 3801596527, 3371927249, 3443181615 10. Some folders seem more susceptible to this problem but I have not been able to identify any common factors/triggers. 11. The problem occurs - on average - once a day. I am happy to provide any further information, configure any debug logging and/or test suggested configuration settings that may help track down the root cause of this problem. Any help gratefully appreciated.

Are the Dovecot Enterprise Edition Ubuntu 14.04 packages stable?
by deoren 07 Jul '15

07 Jul '15

I recently begun to migrate mail services to a new box so I could retrofit an existing box. I took this opportunity to check back on the official Dovecot Enterprise Edition (EE) pages to see if support has been added for Ubuntu 14.04 LTS. I never could find the information on the dovecot.fi website, but taking my existing credentials for Dovecot EE repo access and looking at the root path I see that 14.04 packages are available from the APT repo. Are those stable or experimental? I have an Ubuntu 12.04 box I've kept around just for Dovecot EE that I'd like to move to 14.04 if the packages are stable. p.s. Thank you for continuing to provide access for existing users of the repo, but what would new users need to do to obtain access? Thanks for your time.

Questions about hardlinks, alternate storage and compression
by Gionatan Danti 06 Jul '15

06 Jul '15

Hi all, I have some questions about hardlinks, alternate storage and compression. I already scanned the list for related information and I have an idea of how things works, but I would like to have a definite answer. System spec: - CentOS 6.6 x64 - dovecot-2.0.9-8.el6_6.4.x86_64 RPM package/version - sdbox mail store 1) About hardlinks: when sending the same message to two different recipients, I see that the two u.x files are created as two different files. Diffing them, I see that the only difference is a single char (see [1] for an example). My questions are: a) it is possible to tell dovecot to create a single file + a single hardlink (linkref=2)? As other IMAP servers support that features (eg: Cyrus, CommunigatePro, etc) I am wondering if I missed something in configuring dovecot... b) If it is not possible, can I run a script that compare the various files and substitute equal ones (minus the changing line) with hardlinks, or it will confuse dovecot? As a side note, why the changing line ever exists? 2) About alternate storage and compression: actually, I use a single mail_location without compression. I would like to have an alternate storage and to enable compression on it only, leaving the main location without compression. I if understand it correctly, it _should_ be done using a command similar to "doveadm -Dv -o "plugin/zlib_save=gz" altmove -uu testuser sentbefore 8d". I'm right thinking that it should work? I will really end with a primary uncompressed mail store and an alternate, zlib-compressed one? Thank you all and sorry if I did some naive questions.

Each user has a unique UID but they all have 1 GID (800) My MTA is sendmail I am using dovecot-lmtp for local delivery Mailbox format is mbox Configured managesieve plugin to listen on 4190. (not sure if this is even related but it might) The problem I see is that lmtp(user1) tries to access the home directory /home/user2 and I cannot figure out the reason why. This only happens when sending mails to multiple recipients. I see the that lmtp complains that it doesn't have execute permissions. But I don't want to place execute permissions for others on the entire /home/* dir structure. Also, 700 are the default creation permissions. So new users would have to be chmod'ed manually. (unless there is a setting in dovecot) I used "mailx" to send a test email to multiple recipients `echo "test message" | mailx -s "subject" -r vader at dhcp90.##### han.solo at dhcp90.##### vader at dhcp90.##### tester at dhcp90.#####` The only one who actually receives the message is han.solo at dhcp90.##### and The same happens with aliases in /etc/aliases. `echo "group test" | mailx -s "subject" -r vader at dhcp90.##### grouplist at dhcp90.#####` "grouplist" is defined in /etc/aliases and contains the same users as in the log Any help with this is greatly appreciated.

autocreating folders with special chars stored in mysql-userdb
by Hajo Locke 03 Jul '15

03 Jul '15

Hello, i use dovecot 2.2.18 and do some tests with an utf8 mysqlbackend. I use MySQL to authenticate Users and for retrieving some individual settings like autocreating folders etc. by userdb-settings in user-query. Yet no problems with standard language. Now i try to provide userdb-settings in exotic languages. My MySQL table uses utf8 charset. I store some data in my userdb-column. Here an polish example: "namespace/inbox/mailbox=example namespace/inbox/mailbox/example/name=postępować namespace/inbox/mailbox/example/auto=subscribe" Result is a new folder in dovecot, but in client every special char ę and ć is replaced with a "?" I seems that at some point a conversion to latin1 is performed which ruins the utf8 chars. Creating a folder postępować by imap-client is no problem. Hmm, what should i do now? I dont know how to influence dovecot to process retrieved utf8 data furthermore as utf8. Which charset is using dovecot when connecting to mysqldb and how to take influence? Thanks, Hajo

Dovecot auth username mapping
by Laz C. Peterson 02 Jul '15

02 Jul '15

I have an interesting case here … Virtual mailboxes, domain/username/aliases stored in MySQL, authentication done using PAM. PAM authenticates through Kerberos, which are internal realms and not the email domains — for example, my username would be laz(a)PARAVIS.LOCAL <mailto:laz@PARAVIS.LOCAL> and my email address would be laz(a)paravis.net <mailto:laz@paravis.net>. All of this works just fine. But what I want to do is allow the users to log in using their email address and not their full Kerberos name. It is becoming laborious to help the users understand the difference between their username(a)LOCAL.REALM and username(a)email.address <mailto:username@email.address> and why we have to have two separate identities that mean the same thing. I have the SQL statements to convert either the Kerberos login or the email address to the actual Kerberos login (so they may use either). But I cannot seem to figure out how to get Dovecot to acknowledge this as the mapped username. I’m sure there has to be a way. Any help will be greatly appreciated. Thank you! ~ Laz Peterson Paravis, LLC

Outlook 2013 not fetching new mail/synchronization issues

Hi all, Dovecot 2.2.10 CentOS 6 64 bit. We are having terrible synchronization issues with Outlook 2013 (all updates) on Windows 7 SP1 and 8.1 hosts (all updates). Scenario: 1. Emails were sent since user closed Outlook 2. Next day: start computer, open outlook 3. No new email (even though email were sent overnight) 4. half a day later Outlook fetches emails like nothing happened Second issue: folders created or email send in Outlook 2013 does not synchronize on IMAP, they remain only local .. But I am mostly interested into finding a fix for the first synchronization issue described in scenario. Second is also important but I have a feeling its connected to the first.

duplicate namespace prefix

Hello, I am in the process of setting up a server that is running to invocations of dovecot. One of the invocations is acting as a backend and the other as a Director. I believe I have most of the configuration complete but I keep running into the following error: Jul 01 14:17:04 lda(postmaster(a)mydomain.com: Error: user postmaster(a)mydomain.com: Initialization failed: namespace configuration error: Duplicate namespace prefix: "" Jul 01 14:17:04 lda(postmaster(a)xn--mydomain-8za.com: Fatal: Invalid user settings. Refer to server log for more information. Not sure where to go from here and most of my searches on the error have lead me to dead ends hoping someone can help me out. Thanks.

dovecot-lmtp

Hi, I'm trying to use dovecot-lmtp so that I can filter messages with sieve, however it doesn't appear to be working. I followed the instructions on wiki2.dovecot.org. I'm running Debian Wheezy. I've got runit configured to execute postfix and dovecot, which may be the source of the problem (runit executes /usr/sbin/dovecot -F). I've got mail_debug turned on and there is nothing in the mail log about lmtp.

Dovecot deleting files and directories
by Jan Ekholm 01 Jul '15

01 Jul '15

Hi, I’m a new Dovecot user and using version 2.2.18 on an OpenSuse system. In general it all works quite nicely and clients can connect to Dovecot and manage mails normally. The layout used is maildir. The users are all virtual, i.e. they do not exist on the Linux system. They all log in without any authentication due to a very specialized and internal setup. However, sometimes Dovecot simply deletes mails from the maildir structure. It also seems to delete entire users too. This is not a simple case of clients deleting mails, but the entire folder for the user seems to sometimes get nuked. I’ve also seen that only the mails and Dovecot’s admin files (indexes etc) are deleted. The log file is not really too informative, mostly lines of this form: Jul 01 14:00:36 imap(firstname.lastname(a)domain.x): Info: Disconnected: IMAP session state is inconsistent, please relogin. in=781 out=2630 Jul 01 14:00:36 imap(operators-east(a)east.domain.x): Debug: Namespace : /opt/mail/operators-east doesn't exist yet, using default permissions Jul 01 14:00:36 imap(operators-east(a)east.domain.x): Debug: Namespace : /opt/mail/operators-east doesn't exist yet, using default permissions Jul 01 14:00:36 imap(operators-east(a)east.domain.x): Debug: Namespace : Using permissions from /opt/mail/operators-east: mode=0700 gid=default Jul 01 14:00:36 imap(firstname.lastname(a)domain.x): Debug: Namespace : /opt/mail/firstname.lastname doesn't exist yet, using default permissions Jul 01 14:00:36 imap(firstname.lastname(a)domain.x): Debug: Namespace : /opt/mail/firstname.lastname doesn't exist yet, using default permissions Jul 01 14:00:36 imap(firstname.lastname(a)domain.x): Debug: Namespace : Using permissions from /opt/mail/firstname.lastname: mode=0700 gid=default Jul 01 14:01:03 imap-login: Info: Login: user=<firstname.lastname(a)domain.x>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=9326, secured, session=<2+YiPc4ZGwB/AAAB> Jul 01 14:01:03 imap(firstname.lastname(a)domain.x): Debug: Effective uid=1001, gid=100, home=/opt/mail/firstname.lastname Jul 01 14:01:03 imap(firstname.lastname(a)domain.x): Debug: maildir++: root=/opt/mail/firstname.lastname, index=, indexpvt=, control=, inbox=/opt/mail/firstname.lastname, alt= Jul 01 14:01:07 imap-login: Info: Login: user=<operators-east(a)east.domain.x>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=9333, secured, session=<11NpPc4ZHAB/AAAB> Jul 01 14:01:07 imap(operators-east(a)east.domain.x): Debug: Effective uid=1001, gid=100, home=/opt/mail/operators-east Jul 01 14:01:07 imap(operators-east(a)east.domain.x): Debug: maildir++: root=/opt/mail/operators-east, index=, indexpvt=, control=, inbox=/opt/mail/operators-east, alt= I’ve changed the name and domain. Not sure if the namespace complaints have anything to do with the directories on disk, but normally they are there when the logging comes. Below is the used config file. I can’t see anything that would trigger deletions and there is no logging or similar about it. To me it’s quite serious that an IMAP server randomly deletes mails and its own files. ########################################################################################### # support only IMAP, no pop3 protocols = imap # listen only on IPv4 (the default is: "* ::") listen = * # where logging gets sent log_path = /var/log/dovecot.log # disable SSL ssl = no disable_plaintext_auth = no # we're using maildir without any extra folders in the user's home directory (set in userdb) mail_location = maildir:~ # user ids default_login_user = dovenull default_internal_user = dovecot # auth config auth_verbose = yes auth_mechanisms = plain # password scheme. Uses an external Python application to verify the password. It gets # sent the username and password and can perform authentication. The current one # simply accepts anything. passdb { driver = checkpassword args = /opt/dovecot-2.2.18/bin/checkpassword.py } # user database userdb { driver = static args = uid=navie gid=users home=/opt/mail/maildir/%n } ########################################################################################### Anything obviously wrong? I’ve seen that mail_location and mail_home should not be the same, but using mail_location = maildir:~/mail gives the exact same behavior. Best regards, Jan Ekholm

LDAP default value variable interpolation
by Leon Kyneur 01 Jul '15

01 Jul '15

I'm wondering if there is a way I can dynamically generate an LDAP default value by using variables. I have a configuration that works something like this on my front end proxy: pass_attrs = mail=user,\ =nopassword=y,\ =proxy=y,\ =host=mail.%d The above works perfectly well even though it seems a bit hack. I want to fetch the host field from LDAP and default it to "mail.%d" if the attribute isn't populated for the user. I have tried the following : pass_attrs = mail=user,\ =nopassword=y,\ =proxy=y,\ =host=%{ldap:mailHost:mail.%d} however the interpolation doesn't occur on the default. Just wondering if there is a way to achieve this? thanks

Getting regularly mailbox desyncs while syncing with imapc
by Michael 30 Jun '15

30 Jun '15

Hello list! I sync approximately ~1000 Mailboxes actually without any problems, except my very own mailbox - Dovecot 2.2.18 (mdbox format) running here. The server from where I sync my mails from runs Dovecot 1.2.4 (with mbox format). The last log line that I receive is: dsync(ms(a)ddnetservice.de): Warning: Mailbox changes caused a desync. You may want to run dsync again. dovecot error log: 2015-06-30 13:09:50 imap(ms(a)ddnetservice.de): Error: Corrupted transaction log file /var/vmail/ddnetservice.de/ms/mdbox/mailboxes/INBOX/dbox-Mails/dovecot.index.log seq 2: indexid changed 1435401731 -> 1435662589 (sync_offset=0) This is the command for running my syncs: doveadm -o imapc_user=<remote_user> -o imapc_password=<remote_pw> -o imapc_host=<remote_host> -o imapc_features="rfc822.size fetch-headers" -o mail_prefetch_count=20 -v -D sync -R -u<local_user> imapc: &> $LOGS/$BOX.log A re-run of this command for my mailbox doesn't fix the problem. The "Inbox" remains empty. Only a "doveadm force-resync -ums(a)ddnetservice.de" fixes this problem with the exception that the Inbox still remains empty. So after force-resyncing I need to run the sync again and my Inbox remains consistent until the next imapc sync run. Actually the desync message is self-explanatory, but I wonder why this behaviour only occurs for my own Inbox (only Inbox, other directories aren't affected) and not anywhere else. Is there any possiblity to debug this? Could also the amount of new incoming mails cause this or do I have maybe a bugged mail in my original mailbox that is causing my trouble? Any hint is appreciated. Thanks, Michael

Same-server mail transfer
by Andrew Obertas 30 Jun '15

30 Jun '15

Hello, What would be the best way to perform a same-server Maildir transfer, while retaining the IMAP structure already in place, between users with the same GID but different UIDs? I've tried doveadm import but I presume it is encountering a permissions error due to the different UIDs. Worst case scenario, I could move everything over manually and then update the UIDs. I feel like there should be a more elegant solution though that I'm not immediately grasping however. -- Best regards, Andrew Obertas Junior Systems Administrator Infinet Communications Group

I have cache problem: if I change password at postfixadmin, I can not use the new password to login imap when old password is cached. dovecot log below: Jun 28 11:50:32 auth: Debug: client in: AUTH 6 CRAM-MD5 service=imap securedsession=xjn534sZ9gB/AAAB lip=127.0.0.1 rip=127.0.0.1 lport=143 rport=36342 Jun 28 11:50:32 auth: Debug: client passdb out: CONT 6 PDQzNTU5NTA4MTQxODg5NzUuMTQzNTQ2MzQzMkBtYWlsLmxoeS5jb20udHc+ Jun 28 11:50:32 auth: Debug: client in: CONT<hidden> Jun 28 11:50:32 auth: Debug: cache(test(a)test.example.com,127.0.0.1,<xjn534sZ9gB/AAAB>): hit: <hidden> user=test(a)test.example.com userdb_home=/share/postfix/domains/test.example.com/test/home userdb_mail=maildir:/share/postfix/domains/test.example.com/test userdb_uid=143 userdb_gid=143 Jun 28 11:50:32 auth: Info: cram-md5(test(a)test.example.com,127.0.0.1,<xjn534sZ9gB/AAAB>): password mismatch Jun 28 11:50:34 auth: Debug: client passdb out: FAIL 6 user=test(a)test.example.com Jun 28 11:50:34 imap-login: Debug: Ignoring unknown passdb extra field: Jun 28 11:50:34 imap-login: Info: Disconnected (auth failed, 1 attempts in 2 secs): user=<test(a)test.example.com>, method=CRAM-MD5, rip=127.0.0.1, lip=127.0.0.1, secured, session=<xjn534sZ9gB/AAAB> if I disable "cram-md5" with "auth_mechanisms = plain login". everything is fine. dovecot log below: Jun 28 11:32:24 auth: Debug: cache(test(a)test.example.com,127.0.0.1,<WNsin4sZ6gB/AAAB>): hit: <hidden> user=test(a)test.example.com userdb_home=/share/postfix/domains/test.example.com/test/home userdb_mail=maildir:/share/postfix/domains/test.example.com/test userdb_uid=143 userdb_gid=143 Jun 28 11:32:24 auth: Info: cache(test(a)test.example.com,127.0.0.1,<WNsin4sZ6gB/AAAB>): Password mismatch Jun 28 11:32:24 auth-worker(3711): Debug: sql(test(a)test.example.com,127.0.0.1): query: SELECT username as user, password, '/share/postfix/domains/test.example.com/test/home' as userdb_home, 'maildir:/share/postfix/domains/test.example.com/test' as userdb_mail, 143 as userdb_uid, 143 as userdb_gid FROM mailbox WHERE username = 'test(a)test.example.com' AND active = '1' Jun 28 11:32:24 auth: Debug: client passdb out: OK 15 user=test(a)test.example.com Jun 28 11:32:24 auth: Debug: master in: REQUEST 1951268865 3672 15 0b198494a7e732324f6d6c507b25c13e session_pid=3956 request_auth_token Jun 28 11:32:24 auth: Debug: prefetch(test(a)test.example.com,127.0.0.1,<WNsin4sZ6gB/AAAB>): success Regards, tbskyd

Out of bounds read error in wildcard_match.c
by Hanno Böck 27 Jun '15

27 Jun '15

Hi, I discovered an out of bounds read error in the file wildcard_match.c. Here's the code: /* find the end of each string */ while (*(++mask)); mask--; while (*(++data)); data--; The problem with this: It will search for the end of the strings (zero-terminated), but it'll only start at position 1, not at position 0 (because the ++ in front of the variable will first increment and then return the value). However these strings can be empty. This can be fixed by changing ++mask to mask++ (and same for data), then there must be a -=2 instead of -- afterwards. See attached patch. I found this by compiling dovecot with address sanitizer and running the test suite. cu, -- Hanno Böck http://hboeck.de/ mail/jabber: hanno(a)hboeck.de GPG: BBB51E42

"Sensible" location for Sieve scripts
by Andrew Beverley 26 Jun '15

26 Jun '15

I'm configuring some Sieve scripts for virtual users. I'd like to keep the Sieve scripts somewhere "sensible". Currently, all the mail goes into /var/mail/vhosts/<domain>/<mailbox> So I thought a good place for the sieve script might be in there as well, for example: /var/mail/vhosts/example.com/username/sieve Is there any reason *not* to store the sieve scripts in the same location as the mail? Thanks, Andy

replication notification with chroot users
by Tim Kuijsten 25 Jun '15

25 Jun '15

I'm getting the following error when using dovecot replication: dovecot: imap(foo(a)bar.com): Error: open(/var/dovecot/replication-notify-fifo) failed: No such file or directory I guess this has something to do with the fact that every user is chrooted in it's own homedir.

Namespace Translation / IMAP Proxying
by Daniel van Ham Colchete 25 Jun '15

25 Jun '15

Hello everyone! About three years ago we migrated from Courier do Dovecot using the procedure at http://wiki2.dovecot.org/Migration/Courier. So we have a namespace prefix os "INBOX.". We are trying to implement the SOGo collaboration with Exchange ActiveSync integration with Android Lollipop devices. So, in this exact configuration (namespace prefix + ActiveSync + Android Lollipop) things dont work really well [1]. I'm trying to get an IMAP Proxy of any kind in front of my Dovecot system to translate my namespaces when SOGo connects to it. So instead of presenting INBOX and INBOX.Sent it should show INBOX and Sent. I tried to do it with imapc but couldn't find any configuration that would allow it. I also looked at Perdition IMAP Proxy and NGINX but couldn't find it there also. Does anyone knows a way to do it? Best, Daniel Colchete [1] https://lists.inverse.ca/sogo/arc/users/2015-06/msg00301.html

Fatal: -N parameter requires syncing with remote host
by lejeczek 25 Jun '15

hi I get with default (not declared) replication_dsync_parameters above errors, and for users that I'm trying to disable replication. I'm trying to disable with: override_fields = mail_replica="" in userdb and just in case (ldap) also user_attrs = =mail_replica="" my replication conf is pretty basic: service replicator { process_min_avail = 1 unix_listener replicator-doveadm { mode = 0660 } } service aggregator { fifo_listener replication-notify-fifo { user = vmail group = Domain Users mode = 0660 } unix_listener replication-notify { user = vmail group = Domain Users } } service doveadm { inet_listener { port = 12345 } } doveadm_password = secret # I can tell simple test: doveadm -v sync -f -u my(a)my.domain ssh vmail@server doveadm dsync-server -u me(a)my.domain works. It's for a user that I don't want replication. What am I missing here? many thanks

Re: Virtual Mailboxes
by dmiller＠amfes.com 25 Jun '15

25 Jun '15

My next bonehead maneuver - was more of the first! location = virtual:/var/mail/%%d/%%n/mdbox/mailboxes/virtual was adapted from my definition for my shared namespace. Which was intended to share OTHER users - which is why the '%%' prefixes are used. Changing to: location = virtual:/var/mail/%d/%n/mdbox/mailboxes/virtual Now I can actually view something! But I still have a challenge - the mailboxes don't allow subscriptions via IMAP. If I manually edit the "subscriptions" file I can force it and I can now browse & view - but I can't make changes via IMAP clients.

EXT4/LVM recommendations for 3TB of mdbox ?
by Nicolas C. 25 Jun '15

25 Jun '15

Hello, Do you have recommendations on EXT4 and LVM options for a 3TB file-system for mdbox? We currently use the mbox format on a XFS with poor performances since the update in v2.1 (Debian). We will switch to EXT4 to have the possibility of shrinking the file-system if needed (which is not possible with XFS), we currently have LVM partitions but with mdbox we will use LVM snapshots to backup the server in a consistent state. So, - any particular options to use with mkfs.ext4 for the creation of the FS ? - do you recommend a «thin» logical volume ? Our storage (IBM Storwize v7000) already have thin provisioning capabilities. The server will be a VMware virtual machine running Debian with RDM LUNs of 500GB. Data blocks will be automatically spread across several RAID disk (SSD, SAS, SATA) by the v7000. The «mdbox_rotate_size» will be configured around 10MB. Thanks, Nicolas C.

why would replicated to server ask for extra fs permissions?

is it safe to have two backed used for the same user?

hi everybody I wonder if it is safe (and wise) to have two passw-user databases for the same one user. I'm thinking, mail to me via pam mail to me(a)this.domain via ldap whole Maildir would be essentially the same one storage target, I see permissions have to be mangled, available to write for both vmail and actual uid. what do you think? Is it how it's done? regards

Assert test not compatible with s390(x) and ppc64 architectures

Hi, we have found that assert test fails on some architectures: test-net.c:59: Assert failed: net_addr2ip("127.0.0.1", &ip) == 0 && ip.family == AF_INET && ip.u.ip4.s_addr == (127 | (1 << 24)) It seems as bug in test suit as test is expecting IPv4 address in LE format (0x0100007f), but it gets address in BE format(0x7f000001). Patch in attachment should fix this issue. Regards Michal Hlavinka

a temporary failure
by lejeczek 23 Jun '15

23 Jun '15

dear all I have a postfix relaying to dovecot's lda but "strangely" it does not work, I mean I imaging it's me doing something wrong, yet I cannot figure out what. postfix logs: to=<me(a)my.domain>,orig_to=<root@localhost>, relay=dovecot, delay=39296, delays=39294/2.2/0/0.27, dsn=4.3.0, status=deferred (temporary failure) and dovecot logs no error, despite having debug to yes in couple of places, it shows: auth: Debug: master in: USER 1 me(a)my.domain service=lda auth-worker(25343): Debug: passwd(me(a)my.domain): lookup auth-worker(25343): passwd(me(a)my.domain): unknown user auth: Debug: ldap(me(a)my.domain): user search: base=ou=People,dc=my,dc=domain scope=subtree filter=(&(objectClass=person)(uid=me)) fields= auth: Debug: ldap(me(a)my.domain): result: objectClass=top,top,top,top, ... here goes the whole lot of ldap atrribs, and at the end: unused. For passdb & userdb in the configs I only configure ldap backed, nothing else. Ldap works, I can query it without failling. I believe it's very simple set up but I must be wrong somewhere. pass_filter = (&(objectClass=posixAccount)(uid=%n)) pass_attrs = uid=user=%n,userPassword=password user_attrs = =home=/var/spool/mail/%d/%n,=mail=maildir:/var/spool/mail/%d/%n/Maildir:INDEX=/var/spool/mail/%d/%n:CONTROL=/var/spool/mail/%d/%n user_filter = (&(objectClass=person)(uid=%n)) Any suggestions very appreciated. thanks

Proxy to more Servers

Hi list! Finally I got the LDAP-Authentication work (it was a problem of the OU-Path... :( ). Now I can authenticate the user against the AD and forwarding the IMAP-Connection to the Exchange Server. Wow! My next problem: we have TWO ADs and TWO Exchange-Servers. The first AD has the users for the first Exchange, and the second AD for the second Exchange. I defined two files so: auth-ldap-OLDAD.conf.ext: passdb { driver = ldap args = /etc/dovecot/dovecot-ldap-OLDAD.conf.ext } userdb { driver = ldap args = /etc/dovecot/dovecot-ldap-OLDAD.conf.ext default_fields = imapc_user=%u imapc_password=%w imapc_ssl=imaps imapc_host=sphinx.company.local imapc_port=993 driver=imap uid=imapproxy gid=imapproxy home=/home/imapproxy } auth-ldap-NEWAD.conf.ext: passdb { driver = ldap args = /etc/dovecot/dovecot-ldap-NEWAD.conf.ext } userdb { driver = ldap args = /etc/dovecot/dovecot-ldap-NEWAD.conf.ext default_fields = imapc_user=%u imapc_password=%w imapc_ssl=imaps imapc_host=exchange01.ad.company.org imapc_port=993 driver=imap uid=imapproxy gid=imapproxy home=/home/imapproxy } Well, the authentication works as expected, but when a user of the second AD/Exchanges tries to log in, after a SUCCESSFULLY authentication can't speak with the new Exchange server... :( In the log of Dovecot I see: Jun 23 15:07:58 proxy01 dovecot: imap(chorris): Error: User initialization failed: Namespace '': Mailbox list driver imapc: missing imapc_host Jun 23 15:07:58 proxy01 dovecot: imap(chorris): Error: Invalid user settings. Refer to server log for more information. Could someone explain me, why the configuration for imapc_host in the second file are ignored? Thanks Luca Bertoncello (lucabert(a)lucabert.de)

allowing shell users to change passwords

Does anyone else here have a need to allow shell users to change their imap/pop3 passwords? I came up with a little thing that works similarly to regular passwd(1), dovepasswd, which can be found at https://github.com/DavidGriffith/dovepasswd. It does the job for me and I'd love for other people to take a look and give me some feedback. -- David Griffith dave(a)661.org A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing in e-mail?

Problem with LDAP... again...

Hi list! I'm always trying to configure Dovecot to ask our LDAP-Server (AD) in order to authenticate the users. I really don'know what can I do wrong... I configured my Dovecot so: hosts = chimaera.company.local dn = CN=mailproxy,CN=Users,DC=company,DC=local dnpass = SECRET sasl_bind = no tls = no debug_level = -1 auth_bind = yes ldap_version = 3 base = dc=company,dc=local deref = never scope = subtree user_filter = (&(sAMAccountName=%n)(objectClass=user)) pass_attrs = userPassword=password pass_filter = (&(samAccountName=%n)(objectClass=user)) default_pass_scheme = CRYPT If I try to login in, with my login and password, I see with ngrep that Dovecot ask the AD for my data AND GET THEM, then I see: T 10.0.46.4:49204 -> 192.168.168.23:389 [AP] 0p...ck."DC=DomainDnsZones,DC=company,DC=local................4....samAccountName..bertoncello....objectClass..user0. # T 192.168.168.23:389 -> 10.0.46.4:49204 [AP] 0........e................000004DC: LdapErr: DSID-0C0906E8, comment: In order to perform this operation a successful bind must be completed on the connection., data 0, v1db1.

To say that disabling the use of index files solved your problems is akin to saying amputating your foot solved your bunion problems. Ordinarily, indices ought to be a benefit -- it will help with I/O bottlenecks when mailboxes or number of users get huge. I can't tell from your list of problems whether they are the result of one or many causes, but fixing the index consistency problem would go a long way toward clearing up most of your problems. If INDEX=MEMORY is working for you and you don't see performance degradation, there's no harm in using it, but in my opinion, it may benefit you in the future to get to the bottom of the indexing problem rather than to lop it off altogether. > I am curious if setting INDEX=MEMORY "disables the index completely" as > per http://wiki2.dovecot.org/MailLocation: "If you really want to, you > can also disable the index files completely by appending > :INDEX=MEMORY."

The latter I believe. The important words in the wiki sentence is "index files", not "indexing". Dovecot is still indexing, exept that it builds it from scratch each and every time a worker process accesses a mailbox, so incurs a fixed overhead that cannot be used for the next session.

Dovecot as Proxy for __MORE__ Exchange-Servers
by Luca Bertoncello 22 Jun '15

22 Jun '15

Hi list! I'm trying to configure Dovecot 2.2.18 to act as proxy. Dovecot has to authentificate the users against an LDAP-Server (AD) and then act as IMAP-Proxy to an Exchange Server. Now the problem is, that we have TWO Exchange servers (and two ADs, too). How can I say to Dovecot that it has to search for the user in the first AD (and if found proxy to the first Exchange server) and if the user was not found, to search in the second AD (and if found proxy to the second Exchange server)? Thanks a lot Luca Bertoncello (lucabert(a)lucabert.de)

Quota SQL separate queries?
by Akos Vandra 22 Jun '15

22 Jun '15

Hello, We are trying to enforce per-domain quotas. Currently my quota-sql.conf looks like this: connect = host=/var/run/postgresql dbname=mail user=mailreader map { pattern = priv/quota/storage table = quota username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota username_field = username value_field = messages } With quota = dict:Domain:%d:proxy::sqlquota This works with a trigger by updating and , however I am unable to show the administrators a list of which of their users are using the most space. That is to be purely informative, and is not to be enforced. I would appreciate if there was a documented way to specify exact SQL queries to run for inserting, updating and selecting from the quota storage, something like this: -- CREATE VIEW quota_domain AS SELECT domain, sum(bytes), sum(messages) FROM quotas GROUP BY domain INSERT/UPDATE INTO quotas(username, domain, bytes, messages) SELECT bytes, messages from quota_domain WHERE domain = %d Is there such a possibility? If not, can you suggest a workaround to have a list of per-user quota usages as well as enforced per-domain quotas? Thanks, Akos Vandra

Mailbox aliases problem
by azurIt 22 Jun '15

22 Jun '15

Hi, i'm trying to implement malbox aliases but it's not fully working as i expected. This is my configuration: mail_plugins = acl mailbox_alias plugin { mailbox_alias_old = INBOX/Odoslane mailbox_alias_new = INBOX/SentTest } That 'INBOX/' must be there because of this (we were moving from Courier IMAP): namespace inbox { type = private prefix = INBOX/ separator = / inbox = yes list = yes } All of this is working fine, if i create folder SentTest, the link to folder Odoslane is correctly created on filesystem. The problem is that folder SentTest is invisible even after creation: 1 CREATE "INBOX/SentTest" 1 OK Create completed. 2 LIST "" "*" <all folders except SentTest are listed> 2 OK List completed. 3 LIST "INBOX/SentTest" "*" 3 OK List completed. 4 LIST "INBOX/Odoslane" "*" 4 LIST (\HasNoChildren \Sent) "/" INBOX/Odoslane 4 OK List completed. 5 CREATE "INBOX/SentTest" 5 NO [ALREADYEXISTS] Mailbox already exists 6 DELETE "INBOX/SentTest" 6 OK Delete completed. None of the e-mail clients i tried can see the folder. I'm using Dovecot 2.2.13 from Debian Wheezy (wheezy-backports). Any hints? azur

I'd like to set the quota of a user through the IMAP protocol. I use Pythons imaplib: imap.setquota("test1m(a)uni.dtr", "(storage 8192)") ('NO', ['Quota can be changed only by admin.']) So... which user is the "admin" user in a virtual user setting (passwd: PAM, userdb: LDAP)? Greetings Daniel

I guess this would be a common case, I am hoping for some final clarification. a few Linux boxes share ldap (multi-master) backend that PAM/SSSD uses to authenticated users, and these LDAPs are also is used by Samba, users start @ uid 1000. Boxes are in the same both DNS and Samba domains. Do I treat these users as system or virtual users from postfix/dovecot perspective? If it can be a matter of choice then which is better/best? many thanks.

The first bonehead maneuver seems to be: location = virtual:/var/mail/%%d/%%n/mdbox/virtual I'm thinking it should be: location = virtual:/var/mail/%%d/%%n/mdbox/mailboxes/virtual But...it didn't seem to make a difference. And if I have the "virtual" folder tree under a location other than "/var/mail/domain/user/mdbox/mailboxes" no names appear - so I think I have the files in the right place.

Virtual Mailboxes

Having some trouble with my first attempt at virtual mailboxes. I've enabled the plugin in 10-mail.conf, added a virtual namespace, and created the dovecot-virtual files in the folders. I see the folder names in the list when I refresh the folders available for subscription - but the folders cannot be subscribed to and I can't view their contents.

Dovecot 2.2.16: disappearing messages, mismatched summaries, duplicated messages, excessive full re-downloads
by David Gessel 20 Jun '15

20 Jun '15

My Dovecot 2.2.16 server is interacting poorly with a variety of mail clients. The symptoms include disappearing messages, mismatched summaries, duplicated messages, and excessive full re-downloads. Dovecot 2.2.16 on FreeBSD 10.1-release r280247M ZFS is interacting suboptimally with various email clients. Output of "dovecot -n" further down. *Client Artifacts* Thunderbird 31.6 Win 7 Ultimate SP1: - messages disappear and reappear with checks somewhat randomly. - Sometimes full re-download of folders is triggered, also seems random - Copies of messages appear, sometimes multiplying with each mail check up to about 5-8 or so of each message. - The summary information in the list pane doesn't match the message headers in the preview pane - quit and restart always cleans it up. - sometimes changing folders cleans it up, but not always - sometimes instigating a manual mail check cleans it up but not always Mulberry 4.08 Win 7 Ultimate SP1: - messages disappear and reappear - full re-scans of entire folders triggered occasionally when changing folders, but not always - message list filled with semi-blank entries (message number, status flags, and dates are listed, but no sender, subject, or body is available). The time stamps do not appear to be correct "date received". - message list fills with duplicates - the last of the set of duplicates, which are not necessarily sequentially numbered, has load-able body text and headers, but the others do not. There may be 3-5 copies, only one of which is the real message. The inbox is sequentially numbered by "message number" (the "natural order of the mailbox") and duplicates have unique numbers. - If there's a deleted message left, the "expunge" button is enabled and this also restores normal mailbox view. - disconnecting and reconnecting usually fixes the issues - changing mailboxes while connected sometimes fixes the issues. Claws 3.10.1 Win 7 Ultimate SP1 - initial load is correct, but once claws tries to sync mail, it locks up and never releases (even after days). Claws is weird like that. Sylpheed 3.4.2 Win 7 Ultimate SP1 - mail list always looks fine, but sometimes clicking a message shows "can't display" in the preview pane - "get messages" restores access to messages. Thunderbird 31.5 Linux Mint 17 Qaina 3.13.0-24-generic - messages disappear and reappear with checks somewhat randomly. - Sometimes full redownload of folders is triggered, also seems random - Copies of messages appear, sometimes multiplying with each mail check - The summary information in the list pane doesn't match the message headers in the preview pane - wrong message total (every other client agrees on 2576 but TB-linux says 3242, perhaps counting dups) Claws 3.9.3 Linux Mint 17 Qaina 3.13.0-24-generic - Occasionally shows "this message can't be displayed" - executing a "get mail" fixes the error K-9 5.004 Android 4.3 - messages appear and then disappear on the next check - message body is occasionally blank (only subject and arrival time appear, no body preview line, clicking on the message shows "no text" *Server artifacts:* dovecot.log shows runs of this error: Apr 15 09:02:37 imap(user(a)domain.com): Warning: Maildir /mail/domain.com/user//.Sent: Expunged message reappeared, giving a new UID (old uid=306286, file=1429102024.M826331P1156.host,S=1678,W=1724:2,S) or this error: Apr 15 10:04:00 indexer-worker(user(a)domain.com): Warning: Maildir /mail/domain.com/user//.Sent: Expunged message reappeared, giving a new UID (old uid=306803, file=1428785463.M645546P27215.host,S=5389,W=5442:2,S) # grep -c "Expunged message reappeared" dovecot.log.0 8981 The first entry in dovecot.log.0 is at Apr 15 10:00:12, and the last entry at Apr 15 12:00:13; Dovecot is logging 4,490 expunged message reappeared messages per hour.

I tried removing most of my customizations one by one and testing, but the problem has not been improved. I strongly suspect that the index files are getting thrashed or otherwise abused. I have no idea what's triggering whatever event is resulting in the thousands of expunged messages reappearing, but the client artifacts suggest a mismatch between cache or index files and files on disk: UID, keywords, and set date appear as if from cache but the body of the message does not. It seems as if the UID doesn't match a message on disk any more, which soon gets automatically fixed and everything syncs again until something re-triggers - a false expunge perhaps? Or perhaps the transaction log is suffering some sort of ongoing abuse? *dovecot -n* # dovecot -n # 2.2.16: /usr/local/etc/dovecot/dovecot.conf # Pigeonhole version 0.4.7 # OS: FreeBSD 10.1-RELEASE

I think reason was a damaged Index in ~username/mail/.imap/INBOX/ I removed this folder and immediately errors are gone and Mailbox was readable again. Never noticed this kind of errors for years on 2.1.17, maybe this helps to find a Bug in Code. Thanks, Hajo

Dovecot 2.1.9 shared folder deletion causes fault
by JT 19 Jun '15

19 Jun '15

Hey all, I'm getting a fault in dovecot (see below) using shared folders. I have a mailbox that receives new mail (Account X/INBOX). Another account (Account A) has access to the other account (Account X/INBOX) with ACL below. The ACL directory (.DEFAULT) contains: user=AccountA lrwst I removed a test email from Account A/INBOX, which is supposed to remove the email from Account X/INBOX. A fault occurs whenever my client (Thunderbird) attempts to connect and complete the deletion. Other actions complete successfully. It only appears to happen when using Thunderbird. Mac Mail does not cause the fault. I'm not getting a core dump so all I have is what the log outputs. I can reproduce this regularly so let me know if you need any additional information.

maildir, how to always add size tags to filename (,S=).
by Sergei Franco 19 Jun '15

19 Jun '15

Hi There, I have thoroughly read through documentation and wiki and I simply cannot find how to force dovecot to always add the size tag to the filename when using maildir format. We are using dovecot 2.2.9 (whatever comes from ubuntu 14.04 LTS). We are using dovecot in conjunction with exim with maidirsize file enabled and maildir quotas. For example exim has following configuration: maildir_tag = ,S=$message_size Which adds the size to the filename of the message. This has enormous (orders of magnitude) performance benefit as to calculate quota one does not need to stat every single file (only getents for each directory). I have wrote a script that adds the size tag retrospectively to files it didn't had it, and rebuild the dovecot index/cache if changes where made. This worked fine. Behaviour of dovecot is very peculiar: it generally adds the ,S= tag (along with ,W= tag) but occasionally it does not (I wander if it depends on the IMAP client). Is there anyway to force dovecot to add size tag to the files (like with exim example above)? Thank you very much. Sergei.

Best practices for mailbox network file storage?
by Andy Csillag 18 Jun '15

18 Jun '15

Is there a current best practice for a shared filesystem backend for mailboxes (in my case, all virtual accounts)? NFS 3/4, GFS2, GlusterFS, other? In the case of the latter ones, is the use of Director necessary? Any specific anti-recommendations? Also, if it matters, I *think* I want to use BackBlaze racks for storage. Also, I've seen recommendations for the filesystem underneath like XFS or ext4 or whatever. Is there a best practice? Thanks, Drew

Most of my users are virtual. Do I need defined namespaces or is the default undefined one OK?

LMTP with Postfix Problem
by Steve Matzura 18 Jun '15

18 Jun '15

Here's a maillog entry that's one of many I receive when I try sending a test message to my system. The recipient is a virtual user in /etc/virtual. The way I'm expecting it to work is that my message from me to this Postfix virtual user will be sent back to me. Every time the message delivery is attempted, Dovecot says the LMTP directory doesn't exist. I thought it was created automatically as messages arrive. Jun 18 01:48:27 <machine-name> postfix/lmtp[30644]: 4CA5B8CB6: to=<postmaster@<my-domain>>, orig_to=<postmaster>, relay=none, delay=0.02, delays=0.02/0/0/0, dsn=4.4.1, status=deferred (connect to <my-FQDN>[private/dovecot-lmtp]: No such file or directory)

Pigeonhole vacation from alias address
by Dino Blazeka 18 Jun '15

18 Jun '15

Hi everyone. I've set up my instance not to check recipient address with sieve_vacation_dont_check_recipient=yes to enable users to set up their vacation script without listing addresses (there are to many). Only problem remaining is that when they receive an e-mail sent to their alias, the vacation response comes from their original mail address. Is there a setting or workaround that would enable vacation extension to send response with from field set to whichever address the original message was addressed to. Thank you in advance, Dino P. S. This is my first message to the list so I apologize in advance if I have broken any rules. It was not done intentionally

privilege of process executed by extprograms plugin
by Takahiro Yakoh 18 Jun '15

18 Jun '15

Hi, I'm just a beginner of extprograms plugin of sieve. When I execute a process via execute or pipe command, the process start with "root" privilege. Why? I believe the process must be executed with recipient privilege. Give me some checkpoints, or hints, please. My setup is as follows: Ubuntu 14.04.2 LTS 64bit + dovecot-core, dovecot-sieve plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_execute_bin_dir = /some/where sieve_extensions = +vnd.dovecot.execute +vnd.dovecot.pipe sieve_pipe_bin_dir = /some/where sieve_plugins = sieve_extprograms } protocol lmtp { mail_plugins = " sieve" postmaster_address = postmaster(a)some.where } Yakoh

bug in indexer/indexer-worker
by Infoomatic 18 Jun '15

18 Jun '15

Hi, I have already mentioned this in http://www.dovecot.org/pipermail/dovecot/2014-November/098592.html I could reproduce the errors above in a self-compiled v2.2.18 and the prebuilt packages from xi.rename-it.nl (in addition to version 2.2.15 mentioned in the link) The problem occurs when enabling fts_tika in the plugins (tried tika 1.6, 1.7 and 1.8). I tried to move a folder of my mailbox with about 2000 mails to my server (no users, modern hardware). At some point I get an error and from this time on dovecot keeps repeating the last lines with every mail that comes in ... see [1] I then get kernel syslog messages like in [2]. when I try to index all users (had another testuser) mailboxes with "doveadm index" I get the errors of [3]. The mailfolder does contain mails with attachments of all sorts, videos, office documents etc. When disabling fts_tika it works. dovecot -n output is [4] Could someone of the devs please have a look? best regards, infoomatic [1] Then comes the panic which produces loads of errormessages below the "Raw backtrace" part: Jun 16 10:11:08 testhost dovecot: indexer-worker(user1): Warning: I/O leak:

FTS lucene and english + german mails
by Felix Zielcke 17 Jun '15

17 Jun '15

Hi, I'm currently looking over the FTS pages to enable it in my dovecot. But I'm unsure what the best settings of the lucene plugin are, if you receive german and english mails. Wiki says: textcat_conf=<path> textcat_dir=<path>: If specified, enable guessing the stemming language for emails and search keywords. This is a little bit problematic in practice, since indexing and searching languages may differ and may not find even exact words because they stem differently. On Debian libstemmer is included in the debian-lucene package. So what settings are the best to have not the problem that exact words can't be found?

SOLR 5
by Robert Gierzinger 17 Jun '15

17 Jun '15

Hello, I just wanted to give SOLR 5 a try, however there probably have changed quite some bits in the config files, did not even manage to create a core with various solrconfig.xml and schema.xml files, but I am absolutely no expert in solr. Has anybody given it a try or are there some tips on how to get it running? regards, Robert

dsync userdb and required fields?
by lejeczek 17 Jun '15

17 Jun '15

hi, I'm fiddling with dsync and get these in the logs: auth: Error: password(ps655@): Password data is not valid for scheme SSHA: Input isn't valid base64 encoded data .. auth: Error: ldap(ns580(a),172.25.12.215): ldap_search(base=ou=,ou=mail,dc=virtual,dc=hosting filter=(&(objectclass=person) .... This is on a dovecot that I'd call second, to which I'd like to replicate, first dovecot which is already populated with users, etc. does not show these errors. and I also have seen complains about possixAccunt I think. Do these mean that there is a base minimum required from dovecot/dsync in order to deem/find a user as a valid user? Also I can tell that those users do belong to different domain (not even this RDN) than the one in which the second dovecot is trying to look. These fields/attributes are nowhere defined/mentioned in my configs thus I wonder. many thanks

Imap process crashes when search in virtual mailbox

Mail to nowhere
by Steve Matzura 17 Jun '15

17 Jun '15

The next phase of my testing procedure involves the simple act of delivering mail to my test box. When I send a message to either a valid or relayed user at my remote machine's address, it never gets there. I know this virtually for sure because I'm tailing /var/log/maillog and nothing new has been added for the past hour. I'm thinking eventually my ISP will send the message back to me as undeliverable, and in that bounced message there may be some information about why it was undeliverable, but maybe someone has a thought as to why I'm not even seeing anything attempt to connect?

replication of a big mailbox
by Tim Kuijsten 16 Jun '15

16 Jun '15

I'm running dovecots replicator successfully on 33 mailboxes. There is only one mailbox (the biggest one, 167000 mails) that is not replicating successfully. After 10 minutes the "source" starts logging these messages: dovecot: dsync-local(foo(a)example.com): Error: dsync(imap.netsend.nl): I/O has stalled, no activity for 600 seconds dovecot: dsync-local(foo(a)example.com): Error: Timeout during state=sync_mails (send=mail_requests recv=changes) dovecot: dsync-local(foo(a)example.com): Error: Remote command process isn't dying, killing it dovecot: dsync-local(foo(a)example.com): Error: kill(17459, SIGKILL) failed: Operation not permitted dovecot: doveadm: Error: Pseudo-terminal will not be allocated because stdin is not a terminal. dovecot: doveadm: Error: dsync-remote(foo(a)example.com): Error: Couldn't lock //.dovecot-sync.lock: Timed out after 30 seconds dovecot: doveadm: Error: Pseudo-terminal will not be allocated because stdin is not a terminal. dovecot: doveadm: Error: dsync-remote(foo(a)example.com): Error: Couldn't lock //.dovecot-sync.lock: Timed out after 30 seconds The 30 seconds timeout keeps repeating, while the doveadm process on the destination keeps on going for hours and hours. Destination imap.netsend.nl is creating a lot of hardlinks (at least one hardlink per message) in .temp.... files. This takes about 1,5 hour, after that the number of hardlinks decline again. But it looks like the connection with source is already lost. I've patched the source to overcome the timeout by changing it from 10 minutes to 3 hours[1] but now I'm running into a memory error: dovecot: dsync-local(foo(a)example.com): Error: dsync(imap.netsend.nl): I/O has stalled, no activity for 10800 seconds dovecot: dsync-local(foo(a)example.com): Error: Timeout during state=sync_mails (send=done recv=mails) dovecot: dsync-local(foo(a)example.com): Error: mremap_anon(211677184) failed: Cannot allocate memory The allocate memory error shows up every 10 seconds.

Problem logging in during testing
by Steve Matzura 16 Jun '15

16 Jun '15

Instructions at http://wiki2.dovecot.org/BasicConfiguration say the next thing to test after getting IMAP and Telnet working is to create a dummy user file with the following command: echo "$USER:{PLAIN}password:$UID:$GID::$HOME" > users And place it in /etc/dovecot and protect it appropriately. It was also edited to change the plain-text password from `password' to what it really is. The next section describes changes to 10-auth.conf and other things: If you used the example configuration files, switch to passwd-file by modifying conf.d/10-auth.conf: # Add '#' to comment out the system user login for now: #!include auth-system.conf.ext # Remove '#' to use passwd-file: !include auth-passwdfile.conf.ext In conf.d/auth-passwdfile.conf.ext you should have: passdb { driver = passwd-file args = scheme=CRYPT username_format=%u /etc/dovecot/users } userdb { driver = passwd-file args = username_format=%u /etc/dovecot/users } Verify with doveconf -n passdb userdb that the output looks like above (and there are no other passdbs or userdbs). All done successfully. Now, when I telnet 127.0.0.1 143 and attempt to log in with the string: a login <any username> <any password> whether it's one in my users file or not, I get: a NO [AUTHENTICATIONFAILED] Authentication failed.

What became of dovecot.passwd?
by Steve Matzura 15 Jun '15

15 Jun '15

Since I've decided to go to version 2, which is a lot more difficult to set up because I have to look in a lot more places than I did with version 1.0.15, what do I do with the old dovecot/passwd or its contents? I see no references to it in any of the stuff in conf.d or doc/dovecot/wiki. As always, thanks in advance.

More about my SSL certificate problem
by Steve Matzura 15 Jun '15

15 Jun '15

Someone, I don't remember whether it was Alex or Urban, asked me to check on my private keyfile to see if it began with "Begin RSA private key". I reported that it does not. Now here's where things get strange: When I ran the command: $ openssl req -nodes -newkey rsa:2048 -sha1 -keyout myserver.key -out server.csr on an old Ubuntu system, `myserver.key' does begin with "Begin RSA private key". But when I run that same command on a Fedora 20 system, the word "RSA" isn't there. Could this have anything to do with my 0906D06C error?

dsync replication issues with shared mailboxes

Gentlemen, I've setup 2 servers with dsync replication and hit a serious issue - some messages got duplicated thousands times in some shared mailboxes(~5).

dovecot only partially indexing ... fts
by Infoomatic 14 Jun '15

14 Jun '15

hi, I have a setup using solr as fts, however it seems that when I move messages it does not automatically index the stuff. Also, when using sieve scripts to store messages in different folders I get: dovecot: indexer-worker(user): Indexed 0 messages in testfolder If I get a mail to normal INBOX I get dovecot: indexer-worker(user): Indexed 1 messages in INBOX doveadm index -u user '*' does the trick, however, I have set "fts_autoindex = yes" ... the relevant part of doveconf -n: mail_plugins = fts fts_solr zlib acl quota zlib fts fts_solr acl plugin { fts = solr fts_autoindex = yes fts_solr = url=http://localhost:8983/solr/ break-imap-search sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_extensions = +notify +imapflags } protocol lda { mail_plugins = fts fts_solr zlib sieve acl } protocol imap { mail_plugins = fts fts_solr zlib acl quota imap_acl imap_quota } is this normal behaviour or did I screw something up? TIA, infoomatic

LDA versus LMTP
by Steve Matzura 13 Jun '15

13 Jun '15

My system has a great big four users. The Dovecot wiki says LMTP is more efficient, and someone on IRC told me I'd need it if I were ever to use sieve, which at this time I have no intention of doing. Should I stick with LDA, or just implement LMTP so I'm ready if ever I need it in the future? The bottom line is, it's unclear from the wiki how to explicitly specify use of one or the other, so that's my question.

Non-Existent Log File
by Steve Matzura 13 Jun '15

13 Jun '15

My /var/log/maillog was getting pretty big because of lots of testing and re-configuring I've been doing lately with both Dovecot and Postfix. I figured just remove /var/log/maillog and it would be re-created. It wasn't--not by Dovecot, not by Postfix. I had to manually create a new one, put one character in it, save it, properly secure it with chmod, and then Dovecot (and postfix) messages got written to it. This can't possibly be the proper procedure to clear maillog messages ... can it?

Error when starting Dovecot
by Steve Matzura 13 Jun '15

13 Jun '15

After applying some changes to 10-master.conf as detailed at http://wiki2.dovecot.org/HowTo/PostfixDovecotLMTP I receive the following when trying to start: doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/10-master.conf line 49: Expecting '{' I'm trying to enable LMTP. The instructions say: Socket configuration The actual socket is configured in /etc/dovecot/conf.d/10-master.conf. The LMTP service can be bound to both INET or Unix sockets. In this example a Unix socket is placed inside the Postfix spool with appropriate permissions set: service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } I copied this block and placed it in my copy of 10-master.conf. Line 49 is the first line of this block, and there's clearly a left-brace there. The braces match, too. Thoughts?

Imap Notify
by Tony Morehen 12 Jun '15

12 Jun '15

I'm trying to enable Imap Notify in Dovecot 2.2.13. I know that's a bit out of date, but that's what's provided with openSuSe 13.2. The first thing I did was add mailbox_list_index=yes to /etc/dovecot/dovecot.conf. Both doveadm -n and dovecot -n show the change. I then used doveadm reload to force dovecot to reread its config file. Despite this, NOTIFY did not show up it Dovecot's capabilities: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN] Dovecot ready.

1.0.15 gone, can't start version 2
by Steve Matzura 12 Jun '15

12 Jun '15

On advice/recommendation received on this list, I removed version 1.0.15 with: rm -rf /usr/local/dovecot However, now that I have version 2 properly installed, configured, and ready to start testing with Postfix, it appears the old version is still in /usr/local/sbin, /usr/local/include, /usr/local/libexec, /usr/local/lib and /usr/local/shared/doc. Thinking that anything in /usr/local is something that was installed s a result of having built it from source (which 1.0.15 definitely was), should these also be removed?

Replication: "cross-updates" of mail meta-data
by Andre Nathan 11 Jun '15

11 Jun '15

Hello I have a two-server dovecot setup using replication. Each server runs two dovecot instances, one for director and another for the backend. Initially I set up a single server, got it all working, then rsync'd the data and index partitions to the new one and started the clusters (I used rsync as a way to speed-up dovecot's initial replication). Both servers listen on a virtual IP addresses load-balanced by IPVS as well as their own IP addresses. When I started dovecot in the second server, users started reporting that some of their messages were missing. I noticed that while the mail data seemed to be up to date in server1, it wasn't in server2; however, the indexes were being updated in server2 but not in server1. For example, "doveadm quota get -u some-user" would report the wrong value in server1 and the right value in server2, while a "du" would show that only server1 actually had the most up-to-date data. At the moment I had to take down server2, because as soon as dovecot is running in it, users start reporting missing messages again. To solve that problem, a "doveadm force-resync" in server1 isn't enough. I either rsync the index files from server2 or remove the indexes in server1 before the force-resync, which then works. Has anyone ever saw anything similar to this? Any help would be much appreciated. I'm running Ubuntu 14.04 with dovecot 2.2.15 with the configurations below: === Backend instance === # dovecot -n # 2.2.15: /etc/dovecot/dovecot.conf # OS: Linux 3.16.0-37-generic x86_64 Ubuntu 14.04.2 LTS auth_master_user_separator = * auth_mechanisms = plain login auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@= auth_worker_max_count = 10 disable_plaintext_auth = no doveadm_password = secret doveadm_port = 12345 listen = server1.mydomain.com mail_fsync = never mail_gid = dovemail mail_plugins = " notify replication quota" mail_uid = dovemail managesieve_sieve_capability = fileinto reject envelope vacation subaddress comparator-i;ascii-numeric relational regex copy include vacation-seconds imapflags notify namespace { inbox = yes location = mailbox SPAM { auto = subscribe } prefix = separator = / type = private } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } passdb { args = /etc/dovecot/dovecot-sql-master.conf.ext driver = sql master = yes pass = yes } plugin { mail_replica = tcp:192.168.0.2:12345 #

Order of keys
by Steve Matzura 10 Jun '15

10 Jun '15

I hope I'm asking this on the right list, in the right place. I go through this every three years and for whatever reason keep forgetting to record how this works! In the Dovecot config, there are two places to define SSL certificates--ssl_cert_file and ssl_key_file. My question is this: Which two of the three files--the certifying authority, the signed certificate for the specific system, and the private certificate file--are combined to create the file that goes with ssl_cert_file? Since there are six possible permutations to answer this question (because order of files matters), which two go with ssl_crt_file and in what order? I have a private certificate file, the certifying authority's .CRT file, and the certifying authority's signed .PEM file which contains the system's certified certificate. Thanks in advance.

Dovecot mbox & other programs
by Pali Rohár 09 Jun '15

09 Jun '15

Hello, I want to use dovecot as imap server with mbox storage format (described at [1]) but I also want to access (and modify!) those mbox files which are stored on server (and used by dovecot). What is correct way to read those mboxes? From wiki page [1] I read that I should ignore first message in mbox (which contains X-IMAPbase header) and mbox file is in mboxcl2 format. And what is correct way to modify that mbox file (which is used by dovecot imap)? I would like to configure mutt on server to directly access those mbox mailboxes without need to use imap protocol (over localhost). It is possible without any data/message damage?

special_use \Archive not working with some foldernames
by Hajo Locke 09 Jun '15

09 Jun '15

Hello list, i use dovecot 2.2.18 compiled on my own and want to report an odd behaviour when using a folder for special_use \Archive. In my case it is not working when using some special foldernames (mbox). I compared to version 2.2.15 which i found pre-packaged on launchpad.net, same behaviour. All other special_use Folder work like expected. My situation: We authenticate users using mysql-db. also we allow users to store individuell special_use settings in db. this is a way which was recommended by this mailinglist some years ago. we use a password_query like this: password_query = SELECT `inbox` as `user`, `password`, `home` as userdb_home, `uid` AS userdb_uid, `gid` AS userdb_gid, `userdb_import` AS userdb_userdb_import FROM `mail_users` WHERE `login` = '%u' AND `active`='Y' typical column in db looks like this: | username | cryptedpass | path | inboxname | uid | gid | Y | namespace/inbox/mailbox=Sent namespace/inbox/mailbox/Sent/name=Gesendet namespace/inbox/mailbox/Sent/auto=subscribe namespace/inbox/mailbox/Sent/special_use=\Sent namespace/inbox/mailbox=Drafts namespace/inbox/mailbox/Drafts/name=EntwÃ¼rfe namespace/inbox/mailbox/Drafts/auto=subscribe namespace/inbox/mailbox/Drafts/special_use=\Drafts namespace/inbox/mailbox=Trash namespace/inbox/mailbox/Trash/name=Papierkorb namespace/inbox/mailbox/Trash/auto=subscribe namespace/inbox/mailbox/Trash/special_use=\Trash namespace/inbox/mailbox=Junk namespace/inbox/mailbox/Junk/name=Spam namespace/inbox/mailbox/Junk/auto=subscribe namespace/inbox/mailbox/Junk/special_use=\Junk namespace/inbox/mailbox=Archives namespace/inbox/mailbox/Archives/name=Archiv namespace/inbox/mailbox/Archives/auto=subscribe namespace/inbox/mailbox/Archives/special_use=\Archive | Now i noticed that in this case the folder Archiv was not binded to special_use \Archive: * LIST (\NoInferiors \UnMarked \Junk) "/" Spam * LIST (\NoInferiors \UnMarked \Drafts) "/" Entw&APw-rfe * LIST (\NoInferiors \UnMarked \Sent) "/" Gesendet * LIST (\NoInferiors \UnMarked \Trash) "/" Papierkorb * LIST (\NoInferiors \UnMarked) "/" Archiv * LIST (\HasNoChildren) "/" INBOX If i change the name of folder which is binded to special_use \Archive its working again, no other changes: * LIST (\NoInferiors \UnMarked \Archive) "/" Archiviu or a shorter one: * LIST (\HasNoChildren \Archive) "/" Arc It works in most cases, it is not working if i have chosen name "Archiv". It seems also that autocreating of folder is not working if name is "Archiv". I activated the debug settings but was not helpful. Looks the same in all cases: Debug: Added userdb setting: namespace/inbox/mailbox=Archives Debug: Added userdb setting: namespace/inbox/mailbox/Archives/auto=subscribe Debug: Added userdb setting: namespace/inbox/mailbox/Archives/name=Arc Debug: Added userdb setting: namespace/inbox/mailbox/Archives/special_use=\Archive or: Debug: Added userdb setting: namespace/inbox/mailbox=Archives Debug: Added userdb setting: namespace/inbox/mailbox/Archives/auto=subscribe Debug: Added userdb setting: namespace/inbox/mailbox/Archives/name=Archiviu Debug: Added userdb setting: namespace/inbox/mailbox/Archives/special_use=\Archive or the not working one: Debug: Added userdb setting: namespace/inbox/mailbox=Archives Debug: Added userdb setting: namespace/inbox/mailbox/Archives/auto=subscribe Debug: Added userdb setting: namespace/inbox/mailbox/Archives/name=Archiv Debug: Added userdb setting: namespace/inbox/mailbox/Archives/special_use=\Archive I have no idea what is going wrong here. I have no further hints in my logs. What to do now? Any ideas? Thanks, Hajo

Backup performance may be another big win for Maildir, especially for incremental backups.

Dovecot mailbox indices are self-healing: indices should be rengenerated automatically when the mailbox is out of sync with regards to the indices. There may be a few complaints in the mail logs about it (e.g. UIDVALIDITY changes), but they are mostly harmless. Joseph Tam <jtam.home(a)gmail.com>

Does Dovecot allow different clients to subscribe different subsets of IMAP folders?
by Steve 04 Jun '15

04 Jun '15

I have a working Dovecot IMAP server (v. 2.2.9) where I have a single user but a lot of folders (over 800 in total, hierarchically arranged, about 50 of which are in active use.) I have multiple clients (including k9Mail on Android and Thunderbird on Linux and Windows). These clients all present a consistent subscription to a single subset of the available folders . What I'd like to be able to do is (somehow) allow different devices (different email clients) to subscribe to a different subset of folders. For example, I may want K9mail on my phone to be subscribed only to my "main Inbox" - but for Thunderbird on Windows to also be subscribed to active mailing-list folders. Does Dovecot support such a mode of operation? If so, how do I configure it? If not, what options are there to achieve the desired end result - i.e. different devices/IMAP clients subscribed to different subsets of the universe of folders available to a single user. Mandatory details: Version : 2.2.9 Configuration: See http://paste.ubuntu.com/11564807/

Testing SHA512-CRYPT password hashes with doveadm pw -t fails
by Felix Zielcke 04 Jun '15

04 Jun '15

Hi, I use Debian jessie with Dovecot 2.2.13-11. While writing a script for Horde to change the passwords in my passwd file I noticed doveadm pw -t fails for SHA512-CRYPT: # doveadm pw -s SHA1 -p test {SHA1}qUqP5cyxm6YcTAhz05Hph5gvu9M= # doveadm pw -t {SHA1}qUqP5cyxm6YcTAhz05Hph5gvu9M= -p test {SHA1}qUqP5cyxm6YcTAhz05Hph5gvu9M= (verified) # doveadm pw -s SHA512-CRYPT -p test {SHA512-CRYPT}$6$8FfoioQWQDR/Vuzu$ynKiO/E6Xf4dMvfx2LsP9KQotqy5cEOEppnEh5Hqe1UpCYAgOwSIJlNb0O65fxdYcRZH3gNFQ7ZOM/2kD/R811 doveadm pw -t {SHA512-CRYPT}$6$8FfoioQWQDR/Vuzu$ynKiO/E6Xf4dMvfx2LsP9KQotqy5cEOEppnEh5Hqe1UpCYAgOwSIJlNb0O65fxdYcRZH3gNFQ7ZOM/2kD/R811 -p test doveadm(root): Fatal: reverse password verification check failed: Password mismatch If this can't work for SHA512-CRYPT then at least the error message should be more helpful. Or am I understanding the -t option wrongly? Then this sohuld be maybe somewhere clarified. I just use now doveadm auth test which works fine. Regards, Felix Zielcke

Misleading SSL/TLS Log Messages
by Yahooguntu 03 Jun '15

03 Jun '15

Hi all, I think I've found a small bug in how Dovecot logs SSL/TLS info. Basically, if I connect to the server using TLS, the logs have a lot of entries saying I used SSLv3 (which is not allowed). Here's my system info: OSX Yosemite (x86_64, HFS+) Dovecot 2.2.15 (via Homebrew) OpenSSL 0.9.8zd The configuration (see below) disallows SSLv3, and if I try and connect with OpenSSL to test that ("openssl s_client -connect localhost:993 -ssl3") it fails as expected. If I do the same command, but with "-tls1" instead of "-ssl3", I can connect and run IMAP commands. The problem is, if I open up the Dovecot logs and look at the SSL log messages, they all say I used SSLv3. As an example, this is a truncated log from when I connected to the server and immediately did a LOGOUT: 14:50:59 : master: Warning: Killed with signal 15 (by pid=1 uid=0 code=unknown 0) 14:51:03 : master: Dovecot v2.2.15 starting up for imap, lmtp (core dumps disabled) 14:51:13 : imap-login: Debug: SSL: elliptic curve secp384r1 will be used for ECDH and ECDHE key exchanges 14:51:13 --- last message repeated 1 time --- 14:51:13 : imap-login: Debug: SSL: where=0x10, ret=1: before/accept initialization [127.0.0.1] 14:51:13 : imap-login: Debug: SSL: where=0x2001, ret=1: before/accept initialization [127.0.0.1] 14:51:13 : imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 read client hello A [127.0.0.1] 14:51:13 : imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write server hello A [127.0.0.1] 14:51:13 : imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write certificate A [127.0.0.1] 14:51:13 : imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write key exchange A [127.0.0.1] 14:51:13 : imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write server done A [127.0.0.1] 14:51:13 : imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 flush data [127.0.0.1] 14:51:13 : imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 read client certificate A [127.0.0.1] 14:51:13 : imap-login: Debug: SSL: where=0x2002, ret=-1: SSLv3 read client key exchange A [127.0.0.1] 14:51:13 --- last message repeated 1 time --- 14:51:13 : imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 read client key exchange A [127.0.0.1] 14:51:13 : imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 read finished A [127.0.0.1] 14:51:13 : imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write session ticket A [127.0.0.1] 14:51:13 : imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write change cipher spec A [127.0.0.1] 14:51:13 : imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write finished A [127.0.0.1] 14:51:13 : imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 flush data [127.0.0.1] 14:51:13 : imap-login: Debug: SSL: where=0x20, ret=1: SSL negotiation finished successfully [127.0.0.1] 14:51:13 : imap-login: Debug: SSL: where=0x2002, ret=1: SSL negotiation finished successfully [127.0.0.1] 14:51:19 : imap-login: Aborted login (no auth attempts in 6 secs): user=<>, rip=127.0.0.1, lip=127.0.0.1, TLS, session=<QdX1YaIXTQB/AAAB> 14:51:19 : imap-login: Debug: SSL alert: close notify [127.0.0.1] The second to last line, which indicates I never tried to log in, correctly states that I used TLS.

indexer-worker crashes handling mails with big attachments (dovecot 2.2.16/2.2.18 + FTS Apache Solr + Tika)
by Robinson Bomze 03 Jun '15

03 Jun '15

Hi, yesterday i tried to setup Dovecot with Solr (3.6.2) + Tika (1.8) for FTS. i used a fresh Debian 8.0 system in the beginning with Dovecot 2.2.13 from the Debian repository. After i got some issues with Tika/Dovecot and i read on the mailinglist that these problems where fixed in 2.2.14+, so i tried 2.2.18. With 2.2.18 i get panics with big (ok... huge) attachments. Most mailboxes (and their attachments) get index fine, but on some i got panics from the indexer-worker. i was able to isolate the problem. It seems that when Tika (which works flawless) sends a big reply to Dovecot and Dovecot sends this data to Solr, communication crashes between Dovecot and Solr. Eg. indexing an email with a 200k char wordfile results in a panic of the indexer-worker: Jun 02 23:50:57 indexer-worker(username): Warning: I/O leak: 0x7ff65f39f540 (line 120, fd 20) Jun 02 23:50:57 indexer-worker(username): Warning: Timeout leak: 0x7ff65f39f2e0 (line 325) Jun 02 23:50:57 indexer: Error: Indexer worker disconnected, discarding 1 requests for username Jun 02 23:50:57 imap(username): Error: indexer failed to index mailbox INBOX.username Jun 02 23:50:57 indexer-worker(username): Fatal: master: service(indexer-worker): child 11429 killed with signal 11 (core dumped) I got similar issues results with 2.2.16: Jun 02 23:21:12 indexer-worker(username): Warning: I/O leak: 0x7ffff7811cc0 (line 127, fd 20) Jun 02 23:21:12 indexer-worker(username): Panic: file ioloop.c: line 39 (io_add_file): assertion failed: (callback != NULL) Jun 02 23:21:12 indexer-worker(username): Error: Raw backtrace: /usr/local/lib/dovecot/libdovecot.so.0(+0x77130) [0x7ffff7842130] -> /usr/local/lib/dovecot/libdovecot.so.0(+0x7 Jun 02 23:21:12 indexer: Error: Indexer worker disconnected, discarding 1 requests for username Jun 02 23:21:12 imap(username): Error: indexer failed to index mailbox INBOX.username Jun 02 23:21:12 indexer-worker(username): Fatal: master: service(indexer-worker): child 7909 killed with signal 6 (core dumps disabled) The problem was already posted: http://dovecot.org/pipermail/dovecot/2015-May/100901.html I could trigger the same panic running the indexer via 'doveadm index -u username MAILBOX'.

multi sync (>2 servers) + selective sync + trigger
by b-dovecot.org＠grmbl.net 03 Jun '15

03 Jun '15

Hi all, I've been researching ways to replicate mail across multiple mailstores and have a few questions. Synching 2 mailstores (M1 & M2) via dsync works fine. I want to add a 3rd and 4th (M3 & M4) server to also be synced. Multi-sync (>2 servers): 1) How do I tell M1 and/or M2 to also sync to M3 and/or M4? Selective sync: 2) How do I sync specific domains to specific servers and not to others? Trigger: 3) Does a normal sync check only check the mailbox being changed or does it get triggered on mailbox changes to check ALL indexes and sync all changed mailboxes accordingly? 4) Can I use an email to trigger a sync for any other mailboxes which might be out of sync? TIA B

Outlook Express with XP...
by SH Development 03 Jun '15

Dovecot 2.0.9 I am able to connect successfully with Thunderbird, Win 8, Apple Mail, iPhone, iPad. Outlook Express on Win XP receives just fine, but will not send. I get a "Client host rejected: Access denied” message. I believe this is simply Postfix telling me the connection isn’t properly authenticated, as setting up the exact same credentials on another client (non OE) works. It is only with OE on XP that I am unable to send/authenticate. I have literally tried every combination of settings in OE and nothing works. What else might I need to enable to get this working? Using SSL, ports 993, 587 PLAINTEXT. dovecot -n as follows: # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-504.16.2.el6.x86_64 x86_64 CentOS release 6.6 (Final) ext4 log_timestamp = "%Y-%m-%d %H:%M:%S " mail_location = maildir:/home/vmail/%d/%n/Maildir mail_max_userip_connections = 50 namespace { inbox = yes location = prefix = INBOX. separator = . type = private } passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { mode = 0600 user = vmail } user = root } ssl_ca = </etc/pki/dovecot/certs/intermediate.pem ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { args = uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes driver = static } protocol lda { auth_socket_path = /var/run/dovecot/auth-master log_path = /home/vmail/dovecot-deliver.log postmaster_address = postmaster(a)starionhost.net } protocol pop3 { pop3_uidl_format = %08Xu%08Xv }

As others have noted, your MTA handles the connection. I believe Windows XP needs to be updated to the latest service patch to handle SSLv3 disabled sites. Try checking to make sure your Postfix SSL security settings and your WinXP SSL capabilities are compatible. Joseph Tam <jtam.home(a)gmail.com>

Pop3 service stops responding
by Mike Eriksson 02 Jun '15

02 Jun '15

Hi! I have problem with the pop3 service stops responding at random intervals on my server. We started to notice this problem as we're running icinga to check the imap & pop3 service. When icinga reports that the service is down. We try to telnet to the server on port 110 but it refuses the connection. I've checked the netstat during this time and it's listens on port 110. My first thought we were hitting the max connections and similar. Changed login_max_connections from 128 to 256. Didnt solve the problem. Started the debug on the dovecot server but could not see anything in the logs. Also the error log or the syslog dosnt report anything that I can see. Best thing would of course be to start and upgrade the software and os(Debian 5) but I'm not comfortable upgrading it at the moment as my knowledge about dovecot / postfix isn't great. Do you have any idéas how to move forward? dovecot -n # 1.0.15: /etc/dovecot/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot-error.log info_log_path: /var/log/dovecot-info.log log_timestamp: %Y-%m-%d %H:%M:%S protocols: pop3 imap imaps pop3s ssl_cipher_list: ALL:!LOW disable_plaintext_auth: no login_dir: /var/run/dovecot//login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_max_processes_count: 256 first_valid_uid: 1090 last_valid_uid: 1090 first_valid_gid: 1090 last_valid_gid: 1090 mail_privileged_group: mail mail_location: maildir:~/Maildir mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv auth default: username_chars: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@% username_translation: %@ username_format: %Lu passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: passwd userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail group: vmail plugin: quota: maildir sieve_global_path: /etc/dovecot/sieve_scripts/spam-sort.sieve login_max_processes_count: 256 login_max_connections: 256 max_mail_processes: 1024 Best Regards Mike

Failed running extprograms execute via socket - fatal recv(MSG_PEEK) failed disconnected

I switched from running my extprograms execute script directly to running with dovecot socket. Log shows only this dovecot: lmtp(test(a)example.com): Debug: wdi0Tb5VPlGfPnEAM/SpMA: sieve: action execute: running program: test dovecot: lmtp(test(a)example.com): Debug: Namespace : Using permissions from /vmail/example.com/test: mode=0770 gid=default dovecot: script: Fatal: recv(MSG_PEEK) failed: disconnected For testing I opened up the script and socket with permissions 777 but the error seems to indicate less about permissions more about some kind of protocol problem i guessing. Sieve script calls using this: execute "test"; Plugin config: plugin { sieve_plugins = sieve_extprograms sieve_global_extensions = +vnd.dovecot.execute sieve_execute_socket_dir = sieve-execute sieve_before = /usr/local/etc/dovecot/sieve } service test { executable = script /usr/local/etc/dovecot/sieve_globals/test.sh unix_listener sieve-execute/test { mode = 0660 group = vmail } } FYI I have quota-warning sockets configured identical to this and they work good. Dovecot 2.2.16 Pigeonhole 0.4.7 Help appreciate a lot.

Sieve extprograms ?not exexuting?
by E.B. 01 Jun '15

01 Jun '15

Hello, I was testing the extprograms plugin. I think I had it working in the past, but many things have changed since then, so no use trying to figure out where it broke - starting over again... Debug-enabled log give me: Apr 27 04:11:36 mail dovecot: lmtp(test(a)example.com): Debug: qOGyA0DePHVaOyHEM/SpMA: sieve: action execute: running program: test.sh Apr 27 04:11:36 mail dovecot: lmtp(test(a)example.com): Debug: waiting for program `/usr/local/etc/dovecot/sieve_globals/test.sh' to finish after 0 seconds So I guess it thinks it is running my script? But simple test script does nothing. Here it is: #!/bin/sh read INPUT INPUT="Hello world: $INPUT" echo "$INPUT" >> /tmp/hello echo "---------------------------" >> /tmp/hello Permissions on this script file for now are rwxrwxrwx But nothing goes to /tmp/hello at all. Script works when I run it manually. I also tried without the "read" but I think that's required isn't it? Anyway, what else can I do to debug this? Dovecot 2.2.16 Pigeonhole 0.4.7

OT: Central sieve management
by list＠airstreamcomm.net 29 May '15

29 May '15

A bit off topic, but I was wondering if anyone here has a solution for centrally managing sieve for multiple users from a custom web application? We would like to implement pigeonhole sieve on our dovecot cluster, however we need to be able to access user’s sieve configurations from a central location for troubleshooting and support purposes.

Enabling Master User for migration
by Charles Marcus 29 May '15

29 May '15

Hi all, Ok, just need a quick-n-dirty way to enable a master user for a migration... Reading the docs, I'm not sure what the bare minimum is I need to do this... At: http://wiki2.dovecot.org/Authentication/MasterUsers The Example config shows: auth_master_user_separator = * passdb { driver = passwd-file args = /etc/dovecot/passwd.masterusers master = yes pass = yes } passdb { driver = shadow } userdb { driver = passwd } But, if I'm using a non-real user (just need a master user that can log in as all other users for the migration), do I need all three of these? Or just the first two? Or, just the first one? I think I need the first two and not the last one, but am unsure. This is on a production system so don't want to break things, and I'm unfamiliar with using multiple passdb's... Thanks, Charles

I've read information on the wiki about setting up shared mailboxes, but I want to do something that isn't really coved by the instructions I was reading there. My son (now 7 years old) has an account on the system, but doesn't use it directly. But, for things he's interested in like Minecraft, and/or the local zoo, we have given out his email address in a small number of places. What I would like to set up, both for now while he's not actually ever reading his email himself, and perhaps even for the future when we teach and/or allow for that, is for my wife and I to be able to "view" his inbox from our accounts. The instructions for setting up shared folders all are written so that they're secondary folders to all accounts. Is there a way to either (a) configure sharing someone elses Inbox by other accounts, or (b) setting up a separately configured shared folder to _act_ as the inbox for a single account? Thanks. Any suggestions to achieve the above described end goal would be appreciated. - Chris

Creating IMAP folders/subfolders with Thunderbird
by Alex Regan 29 May '15

Hi, I have dovecot-2.2.15 on fedora21 with Thunderbird and having some difficulty creating subfolders and deleting folders. Creating subfolders results in a folder at the root with a caret instead of a slash called folder^subfolder with an entry in .subscriptions with that name, instead of a new folder under the directory. I'm also unable to delete any folders. The command from within Thunderbird is just completely ignored. Any idea what's happening here? Thanks, Alex

X-UID in mail header is removed?

Dear Dovecot Mailing List, I have 2 questions regarding dovecot and would very much appreciate if you would kindly give me helps. <Question 1> Is 'X-UID' no longer shown in mail header via pop3? I have checked with the following 3 version of dovecot packages in order to make sure if a message sent by dovecot have 'X-UID' in its mail header, and the result is that only "dovecot-0.99.11-10.EL4" shows 'X-UID' and the other ones do not(Please see the result written in the second half of this mail). <Question 2> Is 'X-UID' used for checking if a message has already been sent to a user so that he never gets any duplicated mails that are already in his mbox? The reason why I am asking this here is that I am working on a problem that a user sometimes gets a duplicated mail from dovecot if the user keeps mails on the server as its settings. I actually thought this kind of thing would happen if the 'UIDL' gets corrupted or changed for some reasons. However, it is said that this issue never happened in using "dovecot-0.99.11-10.EL4" which shows 'X-UID' in mail header and in using "dovecot-2.0.9-8.el6_6.4" which does not show 'X-UID', the issue happens sometimes. Thus, I would like information indicating what is exactly used to avoid getting any duplicated messages while downloading a message via pop3 from dovecot. Here is the test result I checked: (dovecot-0.99.11-10.EL4) ]# telnet localhost 110 Trying 127.0.0.1... Connected to localhost.localdomain (127.0.0.1).
