[Dovecot] mdbox with mail_attachment_dir per user in 2.2.12
by Pavel Stano 04 Apr '14

04 Apr '14

Hello, we have 2 netapp arrays with 2 volumes and we need to store our mail data in one or other volume for every user. We want keep data for one user in one volume only. So we would like to have 2 separate mail_attachment_dir, one on every volume. But in latest version 2.2.12 it look like it is only possible to set one global mail_attachment_dir. I have an idea with 2 separate dovecot instances per machine with different mail_attachment_dir. Or it is possible to somehow specify it per user ?

[Dovecot] imap / IPv6 problems?
by Egbert 04 Apr '14

04 Apr '14

Hi, I have this intermittant problem. When sending an email it *sometimes* takes ages before the process finishes. The process seems to hang in moving the message to the sent items" folder". When I disable the IPv6 stack in the network config (this is MS Windows 7), the hanging process immedialetely completes! This makens me think that is has to do with the IP stacks. Another observed effect is a long "rotating wheel" when just klicking on an imap folder before the listing in the right pane updates. Here the same trick solves the problem. I use Thunderbird on W7 as client and have my mail (3 accounts) on a remote mailserver. I have full control over that server which can become handy... Th emailserver is Ubuntu 12.04 LTS with postfix and Dovecot (2.0.19) from the standard repo's. My IPv6 connections is a native IPv6 from my ISP (xs4all.nl). I have no reason to think that the IPv 6 connecition itself is the problem. Any advise to investigate this problem is welcome. Egbert Jan, NL

[Dovecot] xz compression
by T.B. 04 Apr '14

04 Apr '14

Hello Timo, I've successfully setup xz compression for my Dovecot installation using the version 2.2.12 from Debian unstable. Together with the activation of the "Single Instance Attachment Storage", this reduced the mail storage utilization for 20 mail accounts by 74%. *My question:* (For this test just one user was logged in. OS = Debian Wheezy, AMD64) After conversion of my mail storage, IMAP read by Thunderbird worked perfectly. But IMAP write and LMTP write was not possible.* *xz compression seems to need a higher vsz_limit than its default value of 256M without compression. Before the conversion, 256M was enough with the plugins "**acl fts fts_solr" and " imap_zlib". 512M was still not enough for xz compression, 1024M works OK but I'm not sure since this is a relative large increase. My new setting: /etc/dovecot/conf.d/10-master.conf: service imap { vsz_limit=1024M } The absolute minimum to successfully send an empty mail is 710MB (700MB still produces out of memory)! _*Is this normal behaviour? What is a recommended value for "service imap {vsz_limit = }"?*_ I recommend to add this "_vsz_limit"_-increase to the wiki (http://wiki2.dovecot.org/Plugins/Zlib) to make others life easier. Error log below. * **My config & how I converted:* /etc/dovecot/conf.d/10-mail.conf: mail_plugins = *zlib *acl fts fts_solr /etc/dovecot/conf.d/90-plugin.conf: # Enable these only if you want compression while saving: zlib_save_level = 9 # 1..9 zlib_save = xz For "Single Instance Attachment Storage": /etc/dovecot/conf.d/10-mail.conf: # Directory root where to store mail attachments. Disabled, if empty. mail_attachment_dir = /srv/vmail/mail_attachments For compressed IMAP access ( to reduce the bandwidth usage of IMAP ) (has nothing to do with storage space): /etc/dovecot/conf.d/20-imap.conf: protocol imap { mail_plugins = $mail_plugins *imap_zlib* } Previous storage format was standard mdbox Format. To convert a single user, I used dsync from the command line: dsync -u user(a)domain.de mirror mdbox:/srv/converted_vmail/user@domain.de/ After conversion (~2 hours per account), I moved the original mail folder of the user to a backup location and replaced it by the converted folders from "/srv/converted_vmail/user(a)domain.de/". (Pay attention that the directory structure matches!, I had to adjust ist.) *My Problem:* *After conversion IMAP read by Thunderbird worked perfectly**. But IMAP write and **LMTP write was not possible**.** **/var/log/dovecot.log showed that vsz_limit**was to restrictive:* Log: Apr 03 14:13:14 imap(user(a)domain.de): Fatal: lzma: Out of memory Apr 03 14:13:14 imap(user(a)domain.de): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x674f0) [0x7f8538fd54f0] -> /usr/lib/dovecot/libdovecot.so.0(+0x675ce) [0x7f8538fd55ce] -> /usr/lib/dovecot/libdovecot.so.0(i_error+0) [0x7f8538f90678] -> /usr/lib/dovecot/modules/lib20_zlib_plugin.so(o_stream_create_lzma+0xeb) [0x7f8538393ecb] -> /usr/lib/dovecot/modules/lib20_zlib_plugin.so(+0x2c14) [0x7f8538390c14] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_save_begin+0x43) [0x7f85392bdc23] -> dovecot/imap [user(a)domain.de 192.168.1.42 append](+0xd824) [0x7f8539788824] -> dovecot/imap [user(a)domain.de 192.168.1.42 append](cmd_append+0x10e) [0x7f8539788a6e] -> dovecot/imap [user(a)domain.de 192.168.1.42 append](command_exec+0x3c) [0x7f853979390c] -> dovecot/imap [user(a)domain.de 192.168.1.42 append](+0x178ff) [0x7f85397928ff] -> dovecot/imap [user(a)domain.de 192.168.1.42 append](+0x179b5) [0x7f85397929b5] -> dovecot/imap [user(a)domain.de 192.168.1.42 append](client_handle_input+0x125) [0x7f8539792cd5] -> dovecot/imap [user(a)domain.de 192.168.1.42 append](client_input+0x75) [0x7f8539793065] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x27) [0x7f8538fe55c7] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0xd7) [0x7f8538fe6357] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7f8538fe5168] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f8538f95723] -> dovecot/imap [user(a)domain.de 192.168.1.42 append](main+0x2c4) [0x7f8539787324] -> /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xf5) [0x7f8538be6b45] -> dovecot/imap [user(a)domain.de 192.168.1.42 append](+0xc490) [0x7f8539787490] Apr 03 14:13:14 imap-login: Debug: SSL alert: close notify [192.168.1.42] Apr 03 14:13:14 imap(user(a)domain.de): Fatal: master: service(imap): child 23995 returned error 83 (Out of memory (service imap { vsz_limit=256 MB }, you may need to increase it) - set CORE_OUTOFMEM=1 environment to get core dump) ==============================================

You could create MEMORY indices e.g. mail_location = maildir:~/Maildir:INDEX=MEMORY which will allow all the other processing like sieve to work. However, I would look at the cause of the "insufficient privileges": it is a symptom of something that could lead to other problems. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] dovecot 2.2.10 & fts_lucene: Failed to initialize backend
by Benjamin Podszun 03 Apr '14

03 Apr '14

Hey there. (Lesson to self: Don't try to be cute. Somehow a trademark sign breaks my setup and the rest of the mail is discarded? Sorry for the previous, incomplete post) Lurking most of the time here, currently I'm trying to make FTS work. As far as I understand [1], squat is deprecated, solr is a rather big dependency for my 'friends & family' type of installation: Lucene it is! My problem: The lucene backend isn't working, I get this error whenever I try to access it (be it doveadm fts or a search, triggering an index): # doveadm fts rescan -u dar(a)darklajid.de doveadm(dar(a)darklajid.de): Error: fts: Failed to initialize backend 'lucene': Unknown backend doveadm(dar(a)darklajid.de): Error: fts not enabled for user's namespace (null) Any ideas what I might be doing wrong here?

[Dovecot] Disable maildir indexing and dovecot-uidlist on LMTP/LDA delivery
by Jouko Nikula 03 Apr '14

03 Apr '14

Hello all, Is there a way to use LMTP (or LDA) so that maildir index and dovecot-uidlist are not updated? My setup is such that mail delivery sees user's maildir as write only. This setup works well when using postfix for mail delivery, but when I try to switch to dovecot LMTP the lmtp process wants to read the dovecot-uidlist and fails on insufficient privileges. Is there a way around this without exposing the maildir and mail home for read access? Regards, Jouko Nikula

Now to crack on with replication... :-) -Mark
