identify MUA connecting?
by Juan Pablo 29 Jul '14

29 Jul '14

Hello I am using dovecot 1.2.15 on ubuntu. Is it possible to somehow log the MUA information that is connecting to Dovecot? The reason I am wanting to do this is I would like to know if people are getting their email on personal devices instead of work secured / standardized phones.

Missing IMAP Subfolders
by Tim 29 Jul '14

29 Jul '14

I've recently encountered an issue with my IMAP folders on Dovecot 2.0.19. When I telnet into my account and perform a list, I get the following response: A list "" "*" * LIST (\Unmarked) "." "INBOX" A OK List completed. However I know there are subfolders here and have examined the server directly via SSH and strangely: a select INBOX.Clients * OK [CLOSED] Previous mailbox closed. * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 0 EXISTS * 0 RECENT * OK [UIDVALIDITY 1394028715] UIDs valid * OK [UIDNEXT 1] Predicted next UID * OK [HIGHESTMODSEQ 1] Highest a OK [READ-WRITE] Select completed. When I also subscribe to a couple if these which I am able to to do despite not being able to "LIST" them, I get this with LIST-EXTENDED: a04 LIST (SUBSCRIBED RECURSIVEMATCH) "*" "*" * LIST (\Subscribed \NonExistent) "." "INBOX" (CHILDINFO ("SUBSCRIBED")) * LIST (\Subscribed \NonExistent) "." "INBOX.Clients" (CHILDINFO ("SUBSCRIBED")) * LIST (\Subscribed \NonExistent) "." "INBOX.Clients.Bob" a04 OK List completed. Just not sure why a LIST is not giving me a full list as it's causing problems subscribing to these with Mail Clients. Any help is appreciated!

incremental mailbox syncs for quick migration
by Jogi Hofmüller 29 Jul '14

29 Jul '14

Hi all, We are facing quite large mailboxes (>10GB) in our migration from cyrus to dovecot. I did a test on one mailbox and repeated the sync a couple of times with the expected result that the second, third, etc. sync took only seconds compared to minutes for the first sync. We use this command to sync a mailbox: doveadm backup -R -u USER imapc: Are there any problems to be expected when we first do a sync for all mailboxes but do not migrate the users right away but instead do the actual migration using a second sync? Cheers, -- j.hofmüller http://thesix.mur.at/

problem migrating shared folders from cyrus to dovecot
by Jogi Hofmüller 29 Jul '14

29 Jul '14

Hi all, We face a problem migrating shared mailboxes from an old cyrus server to dovecot. Whereas migrating regular users works like a charm, the shared mailboxes cannot be migrated. dsync/doveadm states: "Error: Failed to access mailbox INBOX: Mailbox does not exist". This is somehow true since the shared mailboxes live not under user.mailbox but rather under shared.mailbox (cyrus special). Has anyone a solution for this peculiar problem? Cheers, -- j.hofmüller http://thesix.mur.at/

Multiple servers and NFS
by Richard Hector 29 Jul '14

29 Jul '14

Hi all, For some reason, I didn't go to http://wiki2.dovecot.org/NFS until now, and I'm starting to get worried ... The plan was to have multple servers (MXes) receiving mail, and delivering via LMTP to multiple backend dovecot servers (with amavis in front of dovecot; LMTP both sides). Then we'd have multiple servers for clients to use IMAP or POP3. This is more or less how the system already works, except with Courier IMAP, and postfix on the backends, delivering to maildirs with procmail. But with the recommendation to use the Director for both IMAP/POP3 and LMTP - that starts to sound like I need a whole bunch more servers to run Directors and proxies, and even then it might not be a good idea to have different servers running lmtp and imap/pop. One possible mitigating point is that our 'load balancing' is DNS round-robin, so a given client will probably stick with a single imap/pop server anyway, but if the user has multiple clients (desktop/mobile etc) then they may still hit different servers. Can someone clarify best practice for a setup needing multiple servers for load balancing and redundancy? Is Courier already likely to have been suffering these problems? Oh, the NFS server is a NetApp Filer, if that matters. I'm using dovecot 2.2.9 from debian wheezy backports, in order to get the quota policy daemon support. Thanks, Richard

Dovecot mailstore performance tuning
by Murray Trainer 29 Jul '14

29 Jul '14

HI All, We have a couple of dovecot director proxies and six backed mailstores each accessing mailboxes stored on five NFSv4 filsystems with about 1TB of mail on each in maildir format. We have about 800 max users on each mailstore at peak times and performance appears to starting to degrade at these times. The mailstores are pretty recent hardware with 64GB of RAM and 24 cores. The NFS storage is EMC VNX and we are doing about 250 I/O per sec upto max of 500 on each filesystem. I need to squeeze more performance out of these servers whether that is in the NFS client, Dovecot or Linux OS/kernel areas. We use LDAP for auth and I am doing some tuning in that area. The NFS filesystems are mounted with the options below: 10.11.0.238:/mailbox_store_01 on /home1 type nfs4 (rw,relatime,vers=4.0,rsize=65536,wsize=65536,namlen=255,hard,nordirplus,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=10.11.0.96,local_lock=none,addr=10.11.0.238) My dovecot config is below. I am not seeing any obvious issues in the server logs. Any suggestions on how to improve performance would be appreciated.

Dovecot pigeonhole help sought

I'm running postfix + dovecot + dovecot-pigeonhole on my CentOS-7 home server. I would like spam to finish up in ~/Maildir/.Spam/ .

No, this is a dovecot server running in my own laptop. I guess some computer crash left the mail in an inconsistent state, and I need to assert the extend of the problem.

Segfault dovecot 2.2.9
by Simon Gareste 29 Jul '14

29 Jul '14

Hi all, When trying to set up dovecot, I somehow managed to get a segfault. Trying to launch dovecot from command line (simply execute 'dovecot') results in the error message: Segmentation fault (core dumped) Trying dovecot -n results in pretty much the same: # 2.2.9: /etc/dovecot/dovecot.conf Segmentation fault (core dumped) Looking at syslog, I see doveconf[3676]: segfault at 200 ip 00007fbb93c4fcb3 sp 00007fff005b4c10 error 4 in libc-2.19.so[7fbb93c04000+1bc000] I tried but couldn't find the core dump anywhere on the server. Any help on this would be appreciated too. I (trying to ) run it with postfix, on an Ubuntu 14.04 (Linux mail2.arturia.com 3.13.0-32-generic #57-Ubuntu SMP Tue Jul 15 03:51:08 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux), brand new server. What troubles me even more is that I just set up successfully another mail server a week ago, with the same configuration (diffing the conf folders) except for log or mailbox paths (driver and stuff are the same). In the google search I've done, I saw some stuff about openssl: both servers are running 1.0.1f, since one is running fine, I guess this is not the culprit. One difference I noticed between the two servers is that on the failing one, there is no /var/run/dovecot. I presume this folder and its files are created once dovecot is launched, so that's why it's not present, and is only a symptom of the failure, not a cause? Thanks for your help, and please tell me what other information I could provide to help. Simon

Multiple passwords with sql authentication
by BlackVoid 29 Jul '14

29 Jul '14

I'm currently working on a control panel which is using postfix, dovecot and other applications and I want to add application specific passwords to increase security. I found one solution [1], however it requires the password to be included in the query which is something I do not want to do, because the query may be written in clear-text to log-files. So I'm wondering if there is a way to have multiple passwords with dovecot without risking passwords being leakied in clear-text to log-files.

Migration from mbox/maildir++ to mdbox
by Nima Saed-Samii 28 Jul '14

28 Jul '14

Dear list, dovecot version: 2.1.7 I have an old mail server that uses mboxes for the INBOX and maildirs for subfolders. I want to migrate our mail handling to a new setup using mdboxes for everything. The current config looks like this: # 2.1.7: /etc/dovecot/dovecot.conf doveconf: Warning: service anvil { client_limit=1000 } is lower than required under max. load (1127) # OS: Linux 3.2.0-0.bpo.4-686-pae i686 Debian 6.0.10 auth_mechanisms = plain login disable_plaintext_auth = no first_valid_uid = 114 log_path = /var/log/dovecot.log log_timestamp = "%Y-%m-%d %H:%M:%S " mail_location = mbox:~/Mail/MBox:INBOX=/var/mail/%u mail_max_userip_connections = 30 mail_privileged_group = mail namespace { hidden = yes inbox = yes list = no location = prefix = "#mbox/" separator = / } namespace { location = maildir:~/Mail/Maildir prefix = separator = / } passdb { args = dovecot driver = pam } protocols = imap service auth { client_limit = 1024 user = root } service imap-login { inet_listener imap { port = 0 } process_limit = 1024 } ssl_cert = </etc/ssl/certs/cert-imap.ikp.pem ssl_key = </etc/ssl/private/key-imap.ikp.pem ssl_key_password = ********* userdb { driver = passwd } I would like to use dsync to migrate all to mdboxes and transfer them to the new system.

ACLs on Top level mailboxes.
by Dan Carroll 28 Jul '14

28 Jul '14

Hello, I’m in the process of migrating a mail server to new hardware. At the same time, I’ve made the decision to switch from courier to dovecot (v2.2.13) and from what I have seen so far I’m pretty happy. I have two questions for the list. I’d like my users mailboxes (Maildir format) to look like this: Inbox UserCreatedSubFolder1 UserCreatedSubFolder2 … Sent UserCreatedSubFolder3 Drafts Trash Junk Archives The Top level folders (Sent, Drafts etc) are all “Special” and I do not wish the users to be able to delete them. I also don’t want them to create new Top level folders. This will force all custom folders to be under a Top Level folder. The Maildir format currently looks like this: ~/Maildir/cur ~/Maildir/new ~/Maildir/tmp ~/Maildir/.INBOX/.UserCreatedSubFolder1/cur ~/Maildir/.INBOX/.UserCreatedSubFolder1/new ~/Maildir/.INBOX/.UserCreatedSubFolder1/tmp ~/Maildir/.Sent/cur ~/Maildir/.Sent/new ~/Maildir/.Sent/tmp etc…. I can get ACLs working with dovecot-acl files, and the permission I need (I think is) “owner lrwstipe”. But if I put it into the ~/Maildir directory, then it applies to Inbox. I’ve tried creating an .INBOX dir and putting it in there but that did not work. I also tried some global-acl file settings but I could not make that work either. Basically, I’m wondering how to apply ACLs to the Top level and have different ACLs for the actual inbox when using this scheme. I’m not opposed to changing the Maildir format, but that would mean a lot of work re-doing proemial scripts. My second question relates to migration. Is it enough that I copy the Maildir structure and simply delete the courier files or is it a lot better to use a courier->dovecot migration tool? I realise folder subscriptions would be lost but that’s OK, I’ll recreate them manually anyway. Thanks for your time. -Dan

After upgrade from 2.1 to 2.2.13 clients can create folders with names containing slash character on a Linux system
by David Davidov 28 Jul '14

28 Jul '14

We have following issue: After upgrade from 2.1 to 2.2.13 clients can create folders with names containing slash character. This was not possible with our previous version 2.1. Tested. Our Dovecot runs on Debian Wheezy system. According http://wiki2.dovecot.org/Plugins/Listescape this should be disabled on a Posix system.

[pigeonhole] disregards --with-ldap=no during compilation
by Michael Grimm 28 Jul '14

28 Jul '14

Hi -- I can't get current dovecot and pigeonhole compiled; compilation stops with: | sieve-ldap-db.h:19:10: fatal error: 'ldap.h' file not found Ok, because my dovecot isn't compiled with ldap (--without-ldap), I tried to apply "--with-ldap=no" with configure as advertised in the INSTALL file of pigeonhole, but without success: [...] | ./sieve-ldap-db.h:19:10: fatal error: 'ldap.h' file not found | #include <ldap.h> | ^ | 1 error generated. | gmake[5]: *** [sieve-ldap-db.lo] Error 1 | gmake[5]: Leaving directory `/usr/local/etc/dovecot/SOURCE/dovecot-2.2-pigeonhole/src/lib-sieve/storage/ldap' [...] | gmake: *** [all] Error 2 My configure run logfile shows: [...] | config.status: creating src/lib-sieve/storage/ldap/Makefile [...] | script drivers . : file dict | : -ldap This happens at FreeBSD-STABLE (clang 3.4.1, gmake 3.82) with dovecot at 2d2d75ac6715 and pigeonhole at 1475892e8cff. Any ideas what went wrong? (I'm back to pigeonhole 0.4.3 (1c6130ff5dd6) for the time being.) Thanks and regards, Michael

Hi, Firstly, I'd like to apologise if this is really simple or the answers available easily. I have searched and tried to solve this alone but with no success. I'm having an issue with dovecot to which its reporting "Disconnected (no auth attempts)" in the info log file.

mdbox "doveadm purge" strategy
by Jesus Cea 28 Jul '14

28 Jul '14

Hi there. I am using mdbox storage with great success but I am seeing something I find strange and I would like to compare notes with you. When doing "doveadm purge", "m.*" files with non deleted messages are left alone, but "m.*" files with deleted messages copy the "non deleted" messages to a newly created "m.*" file and delete the original. Good so far. What surprises me is that the newly created "m.*" files are not fullsize. they can be "small" files, not using the 2MB max size I have configured for mdbox storage. Moreover, those files stay in that size forever, no new messages are appended ever. I guess each old "m.*" file with deleted messages generates a new independent "m.*" containing only the non deleted messages. I wonder if that is the case and if that is a fundamental issue that can't be changed. I would like my "m.*" files to use the full configured mdbox size, instead of having quite a few of new SMALL "m.*" files. Thanks for your time and attention!. -- Jesús Cea Avión _/_/ _/_/_/ _/_/_/ jcea(a)jcea.es - http://www.jcea.es/ _/_/ _/_/ _/_/ _/_/ _/_/ Twitter: @jcea _/_/ _/_/ _/_/_/_/_/ jabber / xmpp:jcea@jabber.org _/_/ _/_/ _/_/ _/_/ _/_/ "Things are not so easy" _/_/ _/_/ _/_/ _/_/ _/_/ _/_/ "My name is Dump, Core Dump" _/_/_/ _/_/_/ _/_/ _/_/ "El amor es poner tu felicidad en la felicidad de otro" - Leibniz

struggling with pigeonhole date extensions
by Laeeth Isharc 27 Jul '14

27 Jul '14

I am struggling with how to use the date extension for Dovecot/Pigenhole implementation of Sieve email filtering language. I have read RFC 5260 several times and tried different things with no luck. I would like to place all messages this year up till the end of March into the specified mail folder. What the snippet below actually seems to do is take any messages this year (whether before or after March). Any thoughts? if allof(date :value "eq" :originalzone "date" "year" "2014", date :value "le" :originalzone "date" "month" "3") { fileinto "INBOX/2014 up to Mar"; stop; } Incidentally, it's puzzling how sparse the ecosystem seems to be for managing sieve scripts given the importance of email and the unmanageability of volumes these days without rules. What would be nice to have is something like the Outlook rule manager as a front end and server side sieve scripts on the back. I looked at Modoboa (which seems to be the only standalone option), but it's a bit heavy for my taste and I struggled to configure it in the time I had available. Thanks in advance.

IMAP forward boxes
by Andre Dietrich 26 Jul '14

26 Jul '14

Hi all, since a few weeks I'm experimenting with some "IMAP forward boxes", but I didn't find a satisfactory solution yet. Target function is a directory structure like following in a shared mailbox: /intern/users/fred /intern/users/ted /intern/users/alice The idea is, that a mail, moved to the directory "/intern/users/fred" via IMAP-client will be forwarded to "fred(a)test.domain" without modifying the mail (except the header line "delivered to:"). So if you get a mail in your inbox and want fred to answer it, you drag'n'drop it to /intern/users/fred. Fred gets the mail in his inbox and can answer it. To share all inboxes, to drop mails directly to them, is not an option, because I don't want everybody to see all other inboxes mails. Only to apply "-w-" ACL rights isn't an option either, because it seems to irritate the mail clients. Some month ago I had a partially working solution using a cron bash script. The script read the mails in the cur and new folders, processed the folders path and passed it to sendmail. It's ok, but it has to run quite often to get an adequate forwarding time and on sendmail errors mails got lost without any notification. It would be nice to have a dot-forward file in this subfolder (like in the qmail mailbox root), which is processed by dovecot when a mail is dropped in. Is it possible to solve this with a sieve script, a dot-forward file, or something similar ? I'm grateful for all solutions / ideas ! thx! Andre

Pigeonhole Sieve LDAP support
by Stephan Bosch 25 Jul '14

25 Jul '14

Hi, Yesterday, I committed two important and rather big changes to the Pigeonhole repository. The first creates a generic interface for implementing Sieve script storages. It was already possible to some extent to read Sieve scripts from other sources than the local filesystem, such as Dovecot dict, but that was still pretty limited, as it was not possible to do this with sieve_before/sieve_after. This is now supported. But, more importantly, ManageSieve did not support storing Sieve scripts on locations other than the local filesystem. Now, alternatives can be implemented. Still, I haven't actually implemented write access to a storage other than the local filesystem yet, but now this would be much easier to achieve. The second creates an LDAP script storage implementation. Much like the dict storage, it is still read-only. It can be compiled directly into the Sieve interpreter, and, alternatively, it can also be compiled as a plugin called sieve_storage_ldap. I've updated the documentation in the sources. For all Xi repository users: I added compilation of LDAP storage as a plugin. Read the INSTALL files and other files referenced therein for more information about how to use the plugin. The plugin is installed as part of the dovecot-ldap package. This is a rather big change, but it should all be backwards compatible in terms of configuration. If you have problems (I heard about one so far), please don't hesitate to notify me. Regards, Stephan.

Maildir migration - using separate INDEX and CONTROL directories?
by Richard Hector 24 Jul '14

24 Jul '14

Hi all, I'm working on a migration from Courier to Dovecot, and the courier-dovecot-migrate.pl seems to work ok, but it puts all the metadata files (dovecot-uidlist etc) in the Maildir, while I want to put them in the appropriate places as specified: mail_location = maildir:~/Maildir:INDEX=/var/mail/meta/index/%d/%1n/%1.1n/%n:CONTROL=/var/mail/meta/control/%d/%1n/%1.1n/%n http://wiki2.dovecot.org/Quota/FS explains why some of these files need to go in different places (which is why I'm doing it), but I haven't seen a complete list of what files will be moved as a result of those directives. Is there a handy tool to move the files to the right places? Or is there a complete list of what files need to go where? Thanks, Richard
