[Dovecot] Dovecot has no understandable configuration any more
by forum 30 Apr '13

30 Apr '13

Hello, my last problem could be solved now with userdb { driver = static args = uid=mail gid=mail home=/srv/mail/%d/%n } I can connect to dovecot locally with an webmailer. But there is no listener process to be seen outside of the server? Locally this ports are working, but not outside: # netstat -tulpn | grep dove tcp6 0 0 :::110 :::* LISTEN 5741/dovecot tcp6 0 0 :::143 :::* LISTEN 5741/dovecot tcp6 0 0 :::993 :::* LISTEN 5741/dovecot tcp6 0 0 :::995 :::* LISTEN 5741/dovecot Is this a configuration problem inside dovecot? Another problem is the migration from the existant emails from V1 to V2: In the log i can find: Apr 30 11:14:57 imap(xxxx@yyyy): Error: Broken file /srv/mail/yyyy/xxxx/.INBOX.dir.09/dovecot-uidlist line 1: Broken header (uidvalidity = 0, next_uid=697) How can i recover this? Delete all the index files? Has someone an idea how to migrate the emails from charset ISO8859-1 to UTF-8? Best regards Karsten

[Dovecot] last login timestamp
by Oscar A. Jara 30 Apr '13

30 Apr '13

Hello, I am settiing up a dovecot (imap, pop, sieve, lda) + openldap infrastructure. I need to store the timestamp of the last login of each user in an attribute of its corresponding ldap object. I could not find a way of doing this through configuration options so I am thinking of coding this task into the dovecot-auth source code, maybe in the passdb-ldap.c file. What do you recomend about this? Thanks. __________ Information from ESET Mail Security, version of virus signature database 8278 (20130429) __________ The message was checked by ESET Mail Security. http://www.eset.com

[Dovecot] mailbox_list_index_parse_header crash
by Kyle Wheeler 29 Apr '13

29 Apr '13

Hi, I got all excited about IMAP NOTIFY support and tried enabling mailbox_list_index on my server. Unfortunately, I rather quickly ran into trouble of the segfault variety. This prevented me from doing basic things like seeing the contents of some of my folders. Disabling mailbox_list_index got me back up and running, but... darnit, that's annoying. The only message I got in my log file was this: imap(user@domain): Fatal: master: service(imap): child 6899 killed with signal 11 (core dumped) If I can help track this down, please let me know. Here's the backtrace: #0 hash_table_insert_node (table=0x10eff60, key=0x103, value=0x10fd8b0, check_existing=<value optimized out>) at hash.c:268 node = 0x69616d2d746e6573 prev = 0x10fbee0 hash =

I appreciate this is a special case, but I am using dovecot and solr as it is, according to the documentation, the favourite way. One user is using a large number of archives sub folders, by years, months and subfolders, since 5 years. I am convincing this user to give up this organisation, but in the mean time, I hope to solve this problem. The virtual folder, called Archives, references all the sub folders in the Archive folder. There is about 380 folders, and worst of all, 55k characters with their names concatenated. On solr, I have increased the value of headerBufferSize to a huge value, but I have still this error. Anyway, this is the error I have when I try to index this virtual folder: ---8<--------------------------------------------------------------------------------------------------------------------------------------- root@lapetus:/mnt/emails/indiefield.co.uk/jsmith/Mails/Virtual# doveadm -v index -u 'john smith' 'Search/Archives' doveadm(john smith): Info: Search/Archives: Caching mails seq=109580..127362 1800/17783doveadm(john smith): Panic: file solr-connection.c: line 416 (solr_connection_select): assertion failed: (!conn->posting) doveadm(john smith): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x4414a) [0x7fcb7b5b014a] -> /usr/lib/dovecot/libdovecot.so.0(default_fatal_handler+0x2a) [0x7fcb7b5b020a] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7fcb7b58782a] -> /usr/lib/dovecot/modules/lib21_fts_solr_plugin.so(+0x754a) [0x7fcb790fa54a] -> /usr/lib/dovecot/modules/lib21_fts_solr_plugin.so(+0x4037) [0x7fcb790f7037] -> /usr/lib/dovecot/modules/lib20_fts_plugin.so(fts_backend_get_last_uid+0x5a) [0x7fcb79b2f66a] -> /usr/lib/dovecot/modules/lib20_fts_plugin.so(+0xc1fd) [0x7fcb79b341fd] -> /usr/lib/dovecot/modules/lib20_fts_plugin.so(+0xc689) [0x7fcb79b34689] -> /usr/lib/dovecot/modules/lib20_fts_plugin.so(+0xc51e) [0x7fcb79b3451e] -> doveadm(+0x16719) [0x7fcb7bf71719] -> doveadm(+0x13346) [0x7fcb7bf6e346] -> doveadm(+0x13e21) [0x7fcb7bf6ee21] -> doveadm(doveadm_mail_try_run+0x161) [0x7fcb7bf6f2e1] -> doveadm(main+0x3d1) [0x7fcb7bf6def1] -> /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xfd) [0x7fcb7b200ead] -> doveadm(+0x13125) [0x7fcb7bf6e125] Aborted ---8<--------------------------------------------------------------------------------------------------------------------------------------- On the solr side: ---8<--------------------------------------------------------------------------------------------------------------------------------------- 28-Apr-2013 17:13:33 org.apache.solr.update.processor.LogUpdateProcessor finish INFO: {add=[1/70af772eafc17c51fb350000812a8a77/john smith(a)indiefield.co.uk, 2/70af772eafc17c51fb350000812a8a77/john smith(a)indiefield.co.uk, 3/70af772eafc17c51fb350000812a8a 77/john smith(a)indiefield.co.uk, 4/70af772eafc17c51fb350000812a8a77/john smith(a)indiefield.co.uk, 5/70af772eafc17c51fb350000812a8a77/john smith(a)indiefield.co.uk, 6/70af772ea fc17c51fb350000812a8a77/john smith(a)indiefield.co.uk, 7/70af772eafc17c51fb350000812a8a77/john smith(a)indiefield.co.uk, 8/70af772eafc17c51fb350000812a8a77/john smith@indiefie ld.co.uk, ...

[Dovecot] dovecot-sql.conf - Unknown setting: driver
by jeep＠rahul.net 27 Apr '13

Im upgrading my dovecot from 2.1.14 to dovecot 2.2.1 on linux. Im using the same configuration file against my MySQL db and getting the following error: doveconf -n # 2.2.1: /opt/dovecot221/etc/dovecot/dovecot.conf doveconf: Fatal: Error in configuration file /opt/dovecot221/etc/dovecot/conf.d/dovecot-sql.conf line 2: Unknown setting: driver dovecot-sql.conf: # The mysqld.sock socket may be in different locations in different systems driver = mysql # Use "host= ... pass=foo#bar" if your password has '#' character connect = host=/var/run/mysqld/mysqld.sock dbname=mydb user=username password=pass password_query = SELECT userid AS username, domain, password \ FROM users WHERE userid = '%n' AND domain = '%d' user_query = SELECT home, uid, gid FROM users WHERE userid = '%n' AND domain = '%d' home=/opt/ii/%1n/%n/INBOX # For using doveadm -A: iterate_query = SELECT userid AS username, domain FROM users That file worked fine in the last version. Looking at the docs 'driver' is still a valid setting. Can someone help me figure out why its complaining? Ive even Im lost as to why this error is occuring unless the error itself is actually another problem and the wrong error is popping up. Been working on this for a day and cant figure it out. Thanks in advance! /mf/home/jeep/shell/.signature

[Dovecot] Replication fails with "Remote dsync doesn't use compatible protocol"
by Rich Wales 27 Apr '13

27 Apr '13

I can't get replication to work in Dovecot 2.2.1. I'm getting the following error on the machine where I'm initiating the replication: richatwork dovecot: doveadm: Error: dsync-remote(richatwork): Error: dsync(local): Remote dsync doesn't use compatible protocol Both the local and remote servers are running identical versions of Dovecot (2.2.1), so I don't understand why I would be having any sort of "compatible protocol" problem. Any ideas? I posted the "dovecot -n" output for both servers in my earlier e-mail on this issue, which I sent about 24 hours ago (and which I assume was too long for people to be willing to read).

[Dovecot] ios clients and namespace trouble
by Kelsey Cummings 27 Apr '13

27 Apr '13

We migrated to dovecot from courier and maintained a courier compatible namespace configuration. This resulted in ios clients needing to be manually configured in order to use the special folders correctly (delete messages, save drafts, etc) either by being given the correct "Path Prefix" or by manually selecting the special folders. I can't fathom why apple has chosen not to support or can't detect namespace correctly and require manual configuration but if they haven't done it by now they must have some reason for it and aren't going to fix it any time soon. Are there any creative solutions to fixing the i-clients and preventing them from needing manual configuration? -K

Sorry i am a bit of a noob, the docs don't explain clearly what to do...

[Dovecot] Replication -- multiple users, three or more servers?
by Rich Wales 24 Apr '13

24 Apr '13

I'm running Dovecot 2.2.1 on an Ubuntu 12.04.2 server, with half a dozen accounts for various family members. I want to set up replication involving at least three Ubuntu servers, with different users replicated on different sets of servers. For example, I might have mail for "user1" replicated on "server1", "server2", and "server3"... while mail for "user2" would be on "server1" and "server2"... and mail for "user3" would be on "server1" and "server3". I've read the wiki page (http://wiki2.dovecot.org/Replication) but I'm still confused. I'd love to see an example that clearly shows how to set up specific individual mail users to be replicated on a different set of servers for each user, like what I described above.

[Dovecot] login crashes - maybe too many simultan connections
by Frank Leonhardt 24 Apr '13

24 Apr '13

Hallo, since a few days, users sometimes have problems connecting to our mailserver, in the mail.err are many lines like this: Apr 23 11:14:25 psy2 dovecot: dovecot: child 17607 (login) killed with signal 11 (core dumps disabled) (ip=xx.xx.146.84) Users who are already logged in keep connected, but new connections are not possible.This happens only between 10 am and 3 pm, never in the early morning or at night, so i assume, maybe this is caused by too many simultaneous connections? After restarting dovecot the problem is temporary solved, new users may connect, but after one or a few days, this may happen again. # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.1 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s 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 mail_privileged_group: alle mail_location: maildir:~/Maildir fsync_disable: yes mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 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 auth default: passdb: driver: pam args: dovecot userdb: driver: passwd May anybody help?

[Dovecot] Strange issue with doveadm user
by Antoine Nguyen 24 Apr '13

24 Apr '13

Dear all, I encounter a strange issue with the *doveadm user* command. (dovecot 2.1.16) I try to retrieve information about a specific user but dovecot says it doesn't exist (whereas I just created it). The following command fails: $ sudo -u vmail doveadm user pouet(a)domain.tld userdb lookup: user pouet(a)domain.tld doesn't exist If I try a more global lookup, the user is properly found: $ sudo -u vmail doveadm user *(a)domain.tld user1(a)domain.tld *pouet(a)domain.tld* Sending a query for another user works well. For example : $ sudo -u vmail doveadm user user1(a)domain.tld userdb: user1(a)domain.tld home : /var/vmail/domain.tld/user1 uid : 500 gid : 500 quota_rule: *:bytes=100M I really don't understand what's happening... The only difference I see between the users is that user1 was created when I was using dovecot 1.2... Thanks for your help.

[Dovecot] Feature request: Configure CONFIG_MODULE_DIR and AUTH_MODULE_DIR at runtime
by Rickard Nilsson 23 Apr '13

23 Apr '13

Hi! I am running dovecot 2.1.16 on NixOS (http://nixos.org) and I have been fighting the dynamically loaded dovecot modules/plugins a bit. The problem is that in Nix/NixOS all packages are completely isolated from each other (each package has a separate /lib, /libexec, /bin etc, with only its own files in it). So dovecot has all its modules under /nix/store/xxx-dovecot/{lib,libexec}/dovecot, and the Pigeonhole modules are under /nix/store/yyy-pidgeonhole/{lib,libexec}/dovecot. Now, dovecot wants to load modules only from one directory, so I created a "virtual" package that unifies all modules in /nix/store/zzz-dovecot-plugins/{lib,libexec}/dovecot. I can then use this directory as the "mail_plugin_dir" setting in dovecot.conf. This works fine, dovecot can then find the "sieve" mail plugin. The problem is the service and auth modules, that dovecot tries to load from the compile-time set MODULE_DIR/{settings,auth}. This is a problem for me, because I can't set the module path during compilation since that introduces a circular dependency between the dovecot package and the virtual dovecot-plugins package. I have solved this by hacking dovecot to read an environment variable, DOVECOT_CONFIG_MODULE_DIR, in the config_parse_load_modules function. This way I can inject my module path during runtime. But this only works for the master process, not the config process which seems to reset its environment (I assume it does this when dropping privileges). So I did another hack which lets me pass an argument to the config process which contains the module path. I can then set this argument in dovecot.conf by "service config { executable = config /my/module/path }". These hacks work, and I can now use both the sieve mail plugin and the sieve service. I have attached the patch, but this is not a request to add it to the source. My hack is a hack because I don't know enough about the inner workings of dovecot to solve it in a good way. Rather, I'm asking for some way to configure the module path in dovecot, either as an argument to the master process or as a setting in dovecot.conf. A bonus would be the ability to specify several paths that dovecot would search, then I can do away with my virtual module package. Best regards, Rickard Nilsson

I understand that the +x workaround suggested for the auth-userdb socket (so as to have 0777 permissions instead of 0666) relies on provisions made in Dovecot's code in order to relax some requirements. But I still need help for a correct interpretation... The socket receives 0666 permissions by default; any process should thus be able to read from/write to that socket. So, why set such a default, since it is anyway going to yield un-intuitive results? And, as far as the log messages are concerned: "client doesn't have lookup permissions...". Who's the client here? Still from the log: "client doesn't have lookup permissions for this user:". Which user? "userdb reply doesn't contain uid" The userdb query seems to have failed; but does it mean that is should explicitly return a uid?

[Dovecot] Dovecot 2.1.16: "default_client_count" written to the logs
by Axel Luttgens 23 Apr '13

23 Apr '13

Hello, As to be expected with low system limits, a warning may be written to the logs: master: Warning: fd limit (ulimit -n) is lower than required under max. load (256 < 1000), because of default_client_count Shouldn't it read "default_client_limit" instead of "default_client_count"? It seems that the warning is written only when reloading Dovecot, not upon Dovecot's startup. Is this deliberate? Thanks, Axel

[Dovecot] Integrate mbox into mdbox
by lutz.niederer＠gmx.net 23 Apr '13

23 Apr '13

Hi! I have several mbox files (unstructured, only the big plain mbox files) and I would like to integrate/read these mbox files into mdbox subfolders of specific users. This is a production system and I don't want to disturb running services and I am a bit afraid of not using the right command and maybe destroying (or whatever) their mailboxes. I am sure it is pretty easy. Can someone please tell me the correct dsync command line that I should use to read each mbox file (one-way) into the specific folder of the mdbox folder structure of a specific user? Thanks a lot, -lutzn

[Dovecot] Using dsync to export mail to remote IMAP account
by Joseph Tam 23 Apr '13

23 Apr '13

I've read the web/man pages on dsync, but it's not clear to me whether dsync can be used to export (rather than import) a user's mailbox to a remote non-dovecot IMAP account. (The intention is to use it whenever a user leaves and wants to copy their local mail to Google or whatever. I currently use uw-imapd's mailutil -- it works, but it's dreadfully slow.) As a first crack at it, I tried (on the dovecot server) dsync -o imapc_user=remoteuser -o imapc_password=remotepassword -o imapc_host=remote-imap-server -o imapc_port=993 -o imapc_ssl=imaps -o imapc_features=rfc822.size -o imapc_list_prefix=remoteprefix -o mailbox_list_index=no backup -f -u localuser imapc: I got this error: dsync(localuser): Error: user localuser: Initialization failed: Namespace '': Unknown mail storage driver imapc dsync(localuser): Fatal: User init failed Is exporting mail to a remote (non-dovecot) IMAP account even doable with dsync, or am I completely off-track?

[Dovecot] Dovecot Failover
by Nikolaos Milas 22 Apr '13

22 Apr '13

Hello, Assuming we have two (low traffic) servers (on different data centers) replicated using dsync, what is the best way to automatically direct users to the main server when it is up and to the redundant one when the main server is down? Using DNS? I've seen that DNS-based failover has generally issues (for example: http://serverfault.com/questions/60553/why-is-dns-failover-not-recommended, which is informative although it refers to web servers). What is the suggested approach? HAProxy? Heartbeat/Pacemaker? Any advice will be appreciated. Thanks and regards, Nick

Can you help me please with sieve plugin for dovecot I have this rule: /require ["variables", "envelope", "fileinto", "subaddress", "imap4flags"]; if anyof ( address :is [ "to", "cc", "bcc" ] "test(a)example.com", envelope :contains "to" "test(a)example.com" ) { fileinto "Test"; stop; }/ and if somebody sends me an email with "test(a)example.com" in "TO" or "CC" - then sieve works properly and put this email in Test folder, but i can't understand why if it sends e-mail to "test(a)example.com" in BCC - sieve don't move it to Test but leave it in Inbox? If i run sieve-test -faD .dovecot.sieve "Message-ID" i get: /Performed actions: * store message in folder: Test Implicit keep: (none) sieve-test(root): Info: final result: success/ but in dovecot log i get: /Info: sieve: msgid=<20130421074437.570EA2BA1C1F(a)mail.com>: stored mail into mailbox 'INBOX'/ and email is going to Inbox folder, instead Test. Please tell me what i am doing wrong and how i can make sieve to work properly with BCC. Thank You. -- View this message in context: http://dovecot.2317879.n4.nabble.com/Sieve-BCC-tp41757.html Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] listen directive changed?
by Nick Edwards 20 Apr '13

20 Apr '13

Timo, Is the global listen directive supposed to be a governing directive, like in apache? or is it there just in case you dont use it in protocols? I set a specific ipv6 address in global listen, but use [::] in proto Testing to a secondary IP, not in the global listen, it still connects, so can I ask has the original use of global listen been deprecated? ciao

[Dovecot] Moving mail servers, moving mailboxes
by Gregory Sloop 19 Apr '13

19 Apr '13

So, I've done some searching - but search terms are hard to come by, that work, for this query. In short, migrating a RHEL 5.9 server running the back-ported Dovecot 1.0.7 To: Ububtu 12.04 with 2.0.19, I believe. [I'm not against compiling a more recent version if there's some real advantage to doing so. But I'd certainly prefer to stay with the packaged version.] Most users are POP3, with some leaving messages on the server for a while. Other users are IMAP - whole mail repository on server. --- In an ideal world, I'd like to simply copy all the mailboxes/dirs from one server to the other. [Local/LAN file copies are possible] It would be great if the message ID's wouldn't change, so the read/unread/new etc status all all the messages wouldn't change between the two servers for POP/IMAP. --- So, does anyone have a reasonable walk-through for doing so? Is this a poor idea? Should I simply set myself on fire now and save everyone a lot of hassle? :) Would you suggest an alternative, and tell me if it might achieve the objectives above? I'm more than glad to take pointers to threads on this topic. I just haven't been able to dredge this up with my Google-foo. TIA -Greg

Hello! I try to configure POP3s with Dovecot. My mail server is behind router and I forward 995 port from router to mail server. POP3s works ok when I log directly to 995 on server. Unfortunately, it shows nothing when I log from outside. It happens also when the firewall is off. All I can see in log is this: Apr 19 13:39:43 hostname dovecot: pop3-login: Warning: SSL: where=0x10, ret=1: before/accept initialization [123.123.123.123] Apr 19 13:39:43 hostname dovecot: pop3-login: Warning: SSL: where=0x2001, ret=1: before/accept initialization [123.123.123.123] Apr 19 13:39:43 hostname dovecot: pop3-login: Warning: SSL: where=0x2002, ret=-1: unknown state [123.123.123.123] Apr 19 13:39:43 hostname dovecot: auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Apr 19 13:39:43 hostname dovecot: auth: Debug: auth client connected (pid=17056) Apr 19 13:39:47 hostname dovecot: pop3-login: Disconnected (no auth attempts): rip=123.123.123.123, lip=10.0.0.2, TLS handshaking: Disconnected (hostname and IPs changed) My config: # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-40-generic-pae i686 Ubuntu 12.04.2 LTS auth_debug = yes mail_location = mbox:~/mail:INBOX=/var/mail/%u mail_privileged_group = mail passdb { driver = pam } protocols = pop3 service pop3-login { inet_listener pop3s { address = * } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } verbose_ssl = yes I think it might be something related to SSL, but what?

You can sort of get that from the logs.

Hello Many users here use the "copy to Sent folder" using the IMAP protocol with Dovecot 2.1.15 on a FresBSD 9 server. Since few days this operation ( copy to sent folder ) became longer than before , it could takes several seconds to complete even the message is very short. Is there a parameter I could tweak to boost this a bit ? may users complain with reason thank you

[Dovecot] Problem with "convert" Plugin
by Andreas Schnederle-Wagner - Futureweb.at 18 Apr '13

18 Apr '13

Hello, I got a Problem with the "convert" Plugin. Trying to convert from mbox to maildir Format. OS: CentOS release 5.8 (Final) dovecot -version: 1.0.7 (Centos RPM) convert Plugin call: convert_mail = mbox:/opt/pop3/%u:INBOX=/var/spool/mail/%u When converting to maildir - POP3 works fine (except the lost UIDL - so every server-saved message is double downloaded - but did not find any fix for this problem with convert plugin) But the IMAP In-Boxes give me some headache . All Folders are converted correct - and displayed in Mail Client. But all Mails in the IMAP INBOX are "lost" (at least Mail Client won't show them anymore) Newly delivered Mails to the Inbox work - but all older ones are missing. When looking into this Folder: /var/maildata/USER/Maildir/cur/ I can see that newly delivered mails look like this: 1366122898.14776_0.SERVERNAME:2, And the old - converted ones like this: 1366119758.P14442Q12M682874.SERVERNAME:2, Can someone point me in the right direction why the converted Mails are missing? (It worked on other Servers - about 1 year ago - without any problem?!)

[Dovecot] qmail-ldap LDA Delivery and sieve
by Ruda Porto Filgueiras 18 Apr '13

18 Apr '13

Hi, I'm using dovecot 2.1.7 on debian Squeeze with ldap integration. Almost everything is working fine and I would link to thank all developers for this amazing piece of software. But after changing my qmail-ldap to do LDA integration get all the benefits from LDA and sieve, some emails return with failure like this: <sar(a)mondialline.com.br>: lda(sar): Fatal: Unknown argument: sar Usage: dovecot-lda [-c <config file>] [-a <address>] [-d <username>] [-p <path>] [-f <envelope sender>] [-m <mailbox>] [-e] [-k] It happens on messanges that could not be delivered and need to be returned to the sender. I'm using the configuration described on wiki to do qmail-ldap integration: http://wiki.dovecot.org/HowTo/qmailldap The relevant delivery command is: | /usr/lib/dovecot/dovecot-lda -a $RECIPIENT -f $SENDER -d $USER I also tried to use this way, as documented here: http://wiki2.dovecot.org/LDA/Qmail | /var/qmail/bin/preline -f /usr/lib/dovecot/dovecot-lda But in that case, some sieve plugins can't detect the mail recipient, like vacation plugin. Finally, the vacation plugin also is not doing email forwarding when I use the first delivery option above.

[Dovecot] Pros and cons of having folders under INBOX vs. not
by Rich Wales 18 Apr '13

18 Apr '13

I have some questions about whether I should set up folders under INBOX vs. having them outside the INBOX namespace. I'm setting up a new Dovecot 2.2.0 on an Ubuntu 12.04.2 server. My plan is to move my users (family members) to this new server from an old Cyrus server. Everybody is currently using (and will continue to use) IMAP, and either Thunderbird or SquirrelMail as their e-mail client. I'm using the maildir mailbox format on this new Dovecot server. No one is using the new Dovecot server yet, so I'm still free to do additional tweaking of the server configuration. When I used imapsync to copy everyone's mail to the new server, I found that all the folders (other than INBOX) were renamed. On the old Cyrus server, all the folders are subfolders of INBOX, but the folders on the new Dovecot server are not. (For example, a folder named "INBOX.Dovecot" on the old server was renamed to "Dovecot" on the new server by the imapsync utility.) Can I just keep things this way on the new server? Or are my users going to run into problems if folders are not all under INBOX? I do realize that IMAP servers can be set up either to put everything under INBOX, or not, but I'm not familiar with all the pros/cons. And if I do need (or want) to put all the folders under INBOX, can I simply rename the existing folders in each user's Maildir (and also edit folder names accordingly in everyone's "subscriptions" file)? Or will Dovecot be broken unless I recopy everything from scratch (with a command-line option to imapsync to put everything in the INBOX destination namespace)? Rich Wales richw(a)richw.org

[Dovecot] Dovecot 2.2 & LEMONADE extensions
by Jan Phillip Greimann 18 Apr '13

18 Apr '13

Hi there, I read an article about dovecot 2.2, which includes the LEMONADE extensions, and was fascinated about the feature "Forward without download". We have a small internet-uplink in our office and our CEO loves to receive mails with large attachments, he also reply/forward it, so every time the full attachments get downloaded and uploaded again. Now the question is: Is LEMONADE supported by desktop-mailclients like thunderbird or just mobile Clients? (Google said nothing to this, maybe searched the wrong words) I hope someone can help me with this. Greetings, Jan

[Dovecot] Maildirs location migration
by Thomas Hummel 17 Apr '13

17 Apr '13

Hello Timo, I'm using dovecot-2.1.15 with Maildir mailboxes located on an NFS filer. Postfix is used to deliver mail through procmail ("mailbox_command) as LDA. Our team has bought another filer and everything is meant to go on it, so we're planning to migrate those mailboxes to the new filer. To test it only on a subset of users, I ended up to the following solution : 1. keep new messages in postfix mailqueue for those users (via a service and a transport) 2. prevent new dovecot authentication for those users (via the "auth-deny" passwd-file type passdb) 3. doveadm kick those users 4. copy or rsync the mailboxes 5. symlink maildir, control and indexes directories to the new filer (nfs mounted on the mail server) 6. re-enable mail delivery and imap authentication I was wondering if such a migration could be done differently in order to be seamless to the user : - for the postfix part, it would be easy, I guess, to create a new service (and a new transport map using this service) to deliver to the new location - but for the imap part, I'm not sure if it can be done. My guess is that, if feasible, it would involve some namespace settings and a dsync copy but I cannot figure out how exactly. What do you think ?

[Dovecot] process_limit must be 1
by FABIO FERRARI 17 Apr '13

17 Apr '13

Hello, recently I have migrated a dovecot configuration from a Red Hat 5 to a CentOS 6. Since the versions of dovecot are quite the same (dovecot-2.0.1-1_118.el5 vs dovecot-2.0.9-5.el6.x86_64), I was thinking that copying the configurations file from one server to the other was a good thing, but instead, when I try to start the service, I have this bad error: Avvio di Dovecot Imap: doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf: service(anvil): process_limit must be 1 Does anyone know why I am getting this? Is there a change in configurations between the 2 versions, is it a known issue or I have to check something else? thanks in advance Fabio Ferrari

[Dovecot] %{session} does not work with deliver_log_format
by Daniel Parthey 17 Apr '13

17 Apr '13

Hi, # 2.1.10: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-45-server x86_64 Ubuntu 10.04.4 LTS deliver_log_format = mailbox: deliver: session=<%{session}> msgid=%m from=%f: %$ produces log messages always containing "session=<session}>", like this one: Feb 24 09:22:09 10.129.3.233 dovecot: lmtp(3484, user(a)example.org) mbnWK6/NKVGcDQAAiWCYmA: sieve: mailbox: deliver: session=<session}> msgid=<20130224082208.8A807C0CF(a)mx01.example.org> from=postmaster(a)example.org: stored mail into mailbox 'INBOX/postmaster' http://wiki2.dovecot.org/Variables leads me to the assumption that %{session} works "everywhere" and for deliver_log_format too. Is deliver_log_format variable expansion handled differently from login_log_format_elements and mail_log_prefix? Regards Daniel -- https://plus.google.com/103021802792276734820

[Dovecot] Delete_to_Trash plugin and quota problem
by BINOTTO Luis SIDOR 16 Apr '13

16 Apr '13

Hello list... I am new at dovecot and I have a problem with it; any help will be very grateful We have a exchange server with outlook at the client side, and we are migrating the exchange server to postfix/dovecot(1.2.15) solution. I enabled the "deleted-to-trash" plugin (v0.3) to move the messages to the Trash folder automatically when it is deleted. Also, I am using quota and quota_imap plugins to maintain the quota for users. The quota rule for Trash folder is unlimit. The problem is, when the client reach their maximum quota and try to delete a mail in the inbox to release space. The delete to trash plugin effectively copy it to the Trash folder, but the original mail still remain (marked for delete) at the inbox folder and the quota does not released.

[Dovecot] Sync errors trying to sync old mbox inboxes to dovecot

[Dovecot] [PATCH] mailbox_get_metadata() for mailboxes with open transactions.
by Dafan Zhai 16 Apr '13

16 Apr '13

Hi everyone, I am writing a dovecot statistic plugin, which calls mailbox_get_metadata() to get the virtual size of the mailbox, if a mail is copied. I have noticed that mailbox_get_metadata() calls mailbox_sync(), and mailbox_sync() will fail for the mailboxes with open transactions. But if a mail is copied, there must be at least one transaction opened for the mailbox. So I can not get the virtual size. Commit [1] has fixed the same problem in mailbox_get_status(). I think the same should also be done in mailbox_get_metadata(). See the patch below. Dovecot version: 2.2.0 OS: OS: Linux 3.4.39-dist i686 maildir:~/Maildir:LAYOUT=fs:INBOX=~/Maildir/INBOX Dafan [1] http://hg.dovecot.org/dovecot-2.2/rev/12136db6e31f # HG changeset patch # User Dafan Zhai <dafan.zhai(a)securepoint.de> # Date 1366118323 -7200 # Node ID 7f0c5122d863d303ef5e74bbf650c2bac89ac564 # Parent f33bacb03cc22e02ca2d11d527d8dc0d99214486 lib-storage: mailbox_get_metadata() no longer forces mailbox to be synced.

[Dovecot] Dovecot 2.2 multiple master user passdb's not working anymore
by Christian Wiese 16 Apr '13

16 Apr '13

Hi, after an update from dovecot 2.1.16 to 2.2.0 I encountered a problem when using multiple master user passdb's like the following: ----%<--------------------------------------------------------- passdb { args = /etc/dovecot/passwd.foo-master driver = passwd-file master = yes } passdb { args = /etc/dovecot/passwd.bar-master driver = passwd-file master = yes } ----%<--------------------------------------------------------- The former behavior that the passdb's are searched sequentially to find the given master user doesn't seem to work anymore. Only the first passdb is searched, and thus authentication will fail for all master users which are not defined in the first passdb. Because I cannot find any hint that the master user handling has changed fundamentally it looks like a bug, but maybe I missed configuration related changes from 2.1 to 2.2 that is causing this new behavior. Cheers, Chris

[Dovecot] Probs authenticating to Dovecot
by Kris Magnusson 16 Apr '13

16 Apr '13

Hi folks. I have set up a Ubuntu 12.04 VM with Dovecot, Postfix, MySQL, amavisd, and ISPConfig 3. The VM has tons of RAM and disk and processor and is permanently connected to the Internet with a static IP. I followed the instructions at howtoforge.com to set up and configure this VM and am using ISPConfig to set up a mail hub for multiple domains. I have the DNS for my other domains' MX records pointing at this host—we'll call it "mail." Here's the version of Dovecot I'm using: root@mail:# dovecot --version 2.1.7 Anyway, when I try to connect to my VM and Dovecot using Mail.app on Mountain Lion, I get the following messages in mail.log: Apr 15 01:18:40 mail postfix/smtpd[4284]: connect from 50-196-170-xxx-static.hfc.comcastbusiness.net[50.196.170.xxx] Apr 15 01:18:40 mail dovecot: auth-worker(4331): mysql(localhost): Connected to database dbispconfig Apr 15 01:18:42 mail postfix/smtpd[4284]: warning: 50-196-170-xxx-static.hfc.comcastbusiness.net[50.196.170.xxx]: SASL PLAIN authentication failed: Apr 15 01:18:42 mail postfix/smtpd[4284]: disconnect from 50-196-170-xxx-static.hfc.comcastbusiness.net[50.196.170.xxx] Apr 15 01:18:54 mail dovecot: imap-login: Disconnected (auth failed, 1 attempts in 6 secs): user=<kris>, method=PLAIN, rip=50.196.170.xxx, lip=50.196.170.yyy, TLS, session=<wwn85mHa8AAyxKq9> Apr 15 01:19:04 mail dovecot: imap-login: Disconnected (auth failed, 1 attempts in 10 secs): user=<kris>, method=PLAIN, rip=50.196.170.xxx, lip=50.196.170.yyy, TLS, session=<XGdT52Ha8QAyxKq9> But if I run alpine on mail, I can send and receive mail all day long.

The mailbox is created, it works on the host, so why wouldn't it work over the network? I've tried frobbing settings in Mail.app, as it does have some wonkiness to it, but no dice. The password is fine, everything is in place, it just doesn't work. Any thoughts or recommendations? Thanks, Kris

[Dovecot] [OT] xi.rename-it.nl dovecot-2.2 stable-auto
by Jan Phillip Greimann 16 Apr '13

16 Apr '13

Hi there, I check my mail-server for debian package-upgrades with Nagios, so everyday I got a mail for 8 "new" dovecot-packages on this server. I think that wasn't so in 2.1 stable-auto, but I'm not sure about that. Maybe someone who uses the 2.1 stable-auto repo could response to this? But 2.2 released only few days ago, maybe the repo-admin hadn't time to change this, or my memory about this is wrong. best regards, Jan

[Dovecot] Dovecot IMAPS and slow reconnections
by Jarrad 16 Apr '13

16 Apr '13

Hi List, I've recently moved from postfix + courier-imap to a new server with postfix + dovecot with a mysql user management. I have it up and running and receiving mail ok but I'm having problems with IMAP connections being slow. I have an iphone with multiple imap accounts set up on it (4 I think) and when I open the mail app it connects to first account quickly. Then if I navigate to another account it takes about 1 minute to connect (sits there with the 'connecting....' status) Looking at the logs it shows the connection come through at the same time the iphone actually connects so it's as if something is timing out before it actually connects. My setup is an Amazon EC2 micro instance running debian wheezy. There is about 5 domains being hosted with approximately 4-5 accounts for each so it's not a heavy load by any means. I've tried bumping up the max connections, service_count and minimum processes but nothing seems to help. Any advice is much appreciated. My config is as per below: # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.0 ext4 auth_debug = yes auth_verbose = yes disable_plaintext_auth = no mail_location = maildir:/var/vmail/%d/%n/Maildir namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocols = " imap pop3" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { group = vmail mode = 0600 user = vmail } } service imap-login { process_min_avail = 5 service_count = 10 } ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.key userdb { args = uid=5000 gid=5000 home=/var/vmail/%d/%n/Maildir allow_all_users=yes driver = static } verbose_ssl = yes protocol lda { auth_socket_path = /var/run/dovecot/auth-master log_path = mail_plugins = postmaster_address = <removed for spam reasons> } protocol imap { mail_max_userip_connections = 100 }

[Dovecot] SSHA512 auth not working
by Marcin Czupryniak 16 Apr '13

16 Apr '13

I'm trying to configure SSHA512 passwords and when testing discovered that they were not working as expected. At first i was using Centos 6.4 which doesn't have the glibc CRYPT newest functions ($6$salt$pass) so had to rollback to the Dovecot format ({SSHA512.HEX}saltedpassword+salt ) but I'm unable to let dovecot authenticate properly. Some logs and details: Apr 16 02:55:37 auth: Debug: client in: AUTH 1 PLAIN service=imap lip=xxx rip=xxx lport=143 rport=58171 resp=AGRpbm9AYWJjLml0AGRpbm8= Apr 16 02:55:37 auth: Debug: sql(dino(a)abc.it,xxxx): query: SELECT '{SSHA512.HEX}' || password as password FROM mailboxes WHERE fullusername='dino(a)abc.it' Apr 16 02:55:37 auth: Info: sql(dino(a)abc.it,xxxx): Password mismatch (given password: dino) Apr 16 02:55:37 auth: Error: md5_verify(dino(a)abc.it): Not a valid MD5-CRYPT or PLAIN-MD5 password Apr 16 02:55:37 auth: Warning: Invalid OTP data in passdb Apr 16 02:55:37 auth: Warning: Invalid OTP data in passdb Apr 16 02:55:37 auth: Debug: sql(dino(a)abc.it,xxxx): SSHA512.HEX(dino) != 'd449914d83c85a786bcde7114b3dfdb24a651c27956388ac641d46eaf40c86e7c95ce2534348730475c8893eab314af189b3a46bf6d76b82cfba119e920813a531e985acd35c47ca8d3cafe50b595b66' Apr 16 02:55:39 auth: Debug: client out: FAIL 1 user=dino(a)abc.it Full password as taken from database: {SSHA512.HEX}d449914d83c85a786bcde7114b3dfdb24a651c27956388ac641d46eaf40c86e7c95ce2534348730475c8893eab314af189b3a46bf6d76b82cfba119e920813a531e985acd35c47ca8d3cafe50b595b66 The first 128 chars are the salted password, remaining 32 the salt (hex uuid representation) I've checked twice that the generated passwords are correct, in fact if you salt the password (dino) you get the exact 128chars as in the stored password but dovecot compares the full password with the salt (160 chars), is this correct? Any ideas?

[Dovecot] rsync migration issue

16 Apr '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I am trying to migrate a mail server from an old VM to a new one. I have maildir and virtual users, the files and dirs of the file system are owned by a single user.

[Dovecot] Delete_to_Trash plugin problem
by BINOTTO Luis SIDOR 15 Apr '13

15 Apr '13

Hello list... I am new at dovecot and I have a problem with it; any help will be very grateful We have a exchange server with outlook at the client side, and we are migrating the exchange server to postfix/dovecot(1.2.15) solution. I enabled the "deleted-to-trash" plugin (v0.3) to move the messages to the Trash folder automatically when it is deleted. Also, I am using quota and quota_imap plugins to maintain the quota for users. The quota rule for Trash folder is unlimit. The problem is, when the client reach their maximum quota and try to delete a mail in the inbox to release space. The delete to trash plugin effectively copy it to the Trash folder, but the original mail still remain (marked for delete) at the inbox folder and the quota does not released. Am I doing something wrong? Thanking you in anticipation.... Luis Binotto. " Notificacion Automatica: Este mensaje y cualquier archivo que se adjunte contiene informacion privilegiada y confidencial.

[Dovecot] Dict quota question
by Antoine Nguyen 15 Apr '13

15 Apr '13

Hi all, I'm using Dovecot 2.1.16 and I'd like to know if the following configuration is supported: * An SQL dictionary quota * A static userdb to get uid/gid/home information * An SQL userdb to get per-user quota limit Currenlty, current quota usage are properly stored into the database but per-user limits are not found. If I replace the SQL dictionary by the maildir backend (my previous config.), it works as expected. Do you have any idea? Thanks in advance, Antoine Nguyen http://modoboa.org/

[Dovecot] lazy_expunge plugin with virtual mailboxes
by Gilles Chauvin 15 Apr '13

15 Apr '13

Hi, When using both lazy_expunge and virtual mailboxes (with, for instance, a "All Messages" virtual mailbox) as soon as a user deletes/expunges a mail in one of its mailbox, Dovecot is saving two mails to the lazy_expunge namespace (the one in the user mailbox and the one in the virtual mailbox). Is there some kind of trick to make Dovecot ignore any mail deleted from a virtual mailbox namespace ? Thanks, Gilles.

[Dovecot] How to manually generate a password hash
by David Murphy 14 Apr '13

14 Apr '13

Hi folks. I've recently set up a Postfix 2.9.6/Dovecot 2.0.19 IMAPS/SMTPS setup on Ubuntu 12.04.2 (Mysql backend). I'm new to all this, so I apologize if this is fairly basic. I've attempted to the best of my ability to search for an answer, but no luck so far. What I'm trying to do is generate a password hash that I can inject directly into my Mysql database (disaster recovery sort of situation). Towards that goal, I'm trying to use 'doveadm pw' to generate a hash that matches a known password in my database. Unfortunately, I'm coming up empty. My default_pass_scheme in dovecot-sql.conf is set to MD5-CRYPT, and the passwords in the database have no scheme prefixes. I'm attempting to generate a hash with: sudo doveadm pw -s 'MD5-CRYPT' but the hash generated does not match the user's password hash in the database, which is known to be a good password. I'm able to log into this account successfully in both Roundcube and a remote IMAP client. I've also tried using the -p flag and including the password in the command, and that doesn't do it either, though it oddly gives a different response than using the prompt. (What causes this? Newlines?) So... what am I missing? If the hash was salted, it would seem the hashes in the database would be longer than the ones generated at the command line, but that isn't the case. I'm out of ideas. Any guidance appreciated. -Dave

[Dovecot] LMTP Setup/Design Help Request

Hi again, Thank you for your first hints. I have now set up a dedicated test instance of postfix and dovecot to be able to recreate the problems in detail. Even after using your inputs, they do not seem to work with my setup I already mentioned above. I get errors like postfix/lmtp[10994]: C2DF4C000DF: to=<user1(a)mydomain.org>, relay=mail.mydomain.org[private/dovecot-lmtp], delay=0.1, delays=0.05/0/0/0.04, dsn=5.1.1, status=bounced (host mail.mydomain.org[private/dovecot-lmtp] said: 550 5.1.1 <user1(a)mydomain.org> User doesn't exist: user1(a)mydomain.org (in reply to RCPT TO command)) As stated before, my setup is as follows: > I only have virtual users and have set > > mail_uid = dovemail > mail_gid = dovemail > > For authentication, I simply use (for now) a flat file: > > passdb { > driver = passwd-file > args = scheme=PLAIN username_format=%u /etc/dovecot/mypasswd.file > } > > # cat /etc/dovecot/mypasswd.file > user1:{PLAIN}userpw1 > user2:{PLAIN}userpw2 > user3:{PLAIN}userpw3 > > And everything works fine with IMAP. I am completely domain-agnostic > here. I do not know how to strip the domain when the username is handed over from postfix to dovecot, and what would be the sane solution. I hope, you can give me a hint to that. Thank you, again, and greetings, Matthias Hofer

I did not think about that, but this solved this issue :D Thank you a lot. And I was now able to solve also my further issues. So I am prepared to try again to switch :) Have great day!

Putting pop3 in /etc/hosts.deny with the associated ip seems to work, like so: pop3: 166.84.1.2 or imap imap: 166.84.1.2 (are there any challenges to this?) Given that services such sendmail and sshd respond to sshd: xxx.xxx.xxx.xxx sendmail: xxx.xxx.xxx.xxx I thought that it should be dovecot: xxx.xxx.xxx.xxx As a suggestion, can dovecot binaries for distributions such as CentOS and Fedora be compiled with tcp wrappers by default? > - Richard Much thanks.

[Dovecot] Questions about the upcoming Object Storage Plugin for 2.2
by Charles Marcus 11 Apr '13

11 Apr '13

Hi Timo, I'm curious and have questions about the new Object Storage Plugin (OSP), and how it can be leveraged by an SMB like us. First, am I reading this right where it could be used as a kind of 'live/realtime backup' solution, where everything is stored *both* locally and in the cloud, with two-way syncing, ie, so local users could access the local server for faster access, and when outside the office, they'd access the cloud based storage and any changes made there are sync'd back to the local server? Or is it intended to be more as an alternative storage for storing older emails in a separate namespace? Or both/either? Second, is SIS fully supported by the OSP? Third - I'm a little confused by the Amazon S3 pricing page, especially on how to try to estimate the costs for usage (bandwidth, etc)... do you have any idea how to go about estimating that? Is there some kind of process we could use on our existing server to measure it over a given period of time that would give us an estimate of what to expect if we decided to switch over? Last - have you established pricing for the OSP? Will it be per user, or per MB/GB, per month (or per year), or just a one-time cost? And/or will you include/bundle it with any/all of your support tiers? Sorry if I'm jumping the gun here... Thanks, really looking forward to the 2.2 release! -- Best regards, Charles

[Dovecot] Configuring dovecot to use tcp wrappers
by Max Pyziur 11 Apr '13

11 Apr '13

Greetings, I am looking to implement tcp wrappers with dovecot; I am using the following two links as guides to configuration: http://blog.acsystem.sk/linux/brute-force-attack-dovecot-imap-server-blocki… http://wiki2.dovecot.org/LoginProcess (you need to go to the very bottom) I'm concerned in making the configuration correctly. If you set login_access_sockets = tcpwrap in /etc/dovecot/dovecot.conf Then everything accessing ports controlled by dovecot (and open by iptables) is blocked. So my question relates to the second part of the configuration examples in the links above: service tcpwrap { unix_listener login/tcpwrap { group = $default_login_user mode = 0600 user = $default_login_user } } Where does this code get placed (in dovecot.conf or in one of the files in /etc/dovecot/conf.d)? And regarding $default_login_user, it appears in a comment line in /etc/dovecot/conf.d/10-master.conf Should that line be uncommented? Much thanks.

[Dovecot] [PATCHES] NetBSD support, authentication buffer size
by Emmanuel Dreyfus 11 Apr '13

11 Apr '13

Hi Here are a few unintegrated patches, just tested against 2.2rc7: 1) NetBSD's getmntinfo uses struct statvfs while other BSD use struct statfs http://ftp.espci.fr/shadow/manu/patch-ak 2) NetBSD 5.x net_getunixcred() support. Build on NetBSD, but not tested (I am testing on NetBSD 6.0): http://ftp.espci.fr/shadow/manu/patch-src_lib_net.c 3) Increase authentication buffer size so that it can cope with unusual authentication scheme. This patch was integrated in dovecot-1.x but did not make its way in dovecot-2.x http://ftp.espci.fr/shadow/manu/patch-src_lib-master_master-auth.h -- Emmanuel Dreyfus manu(a)netbsd.org

[Dovecot] Easy way to make all mailboxes of a user read-only
by Stephan von Krawczynski 11 Apr '13

11 Apr '13

Hello all, I try to configure dovecot to make all imap accesses read-only for a certain user. I thought this would be possible by creating a global acl file (here "global-acl") like: user=<username> lr and plugin { acl = vfile:/etc/dovecot/global-acls:cache_secs=300 } But that seems to be ignored. What is wrong with this idea, the docs are not really clear about a single acl file with global settings. -- Regards, Stephan

[Dovecot] v2.2.rc7 released
by Timo Sirainen 11 Apr '13

11 Apr '13

http://dovecot.org/releases/2.2/rc/dovecot-2.2.rc7.tar.gz http://dovecot.org/releases/2.2/rc/dovecot-2.2.rc7.tar.gz.sig OK, still not quite v2.2.0, but now it's definitely very close. :) * checkpasword: AUTH_PASSWORD environment is no longer set. * Running dsync no longer triggers quota warnings. + dsync: Commit large transactions every 100 new messages, so if a large sync crashes it doesn't have to be restarted from the beginning. - replicator: doveadm commands and user list export may have skipped some users. - Various fixes to mailbox_list_index=yes

[Dovecot] Dovecot distribution configuration files source
by Dave Gattis 11 Apr '13

11 Apr '13

Where can I find unaltered distribution config files (/etc/dovecot/ and /etc/dovecot/config.d/) for Dovecot 2.1.7? I upgraded from version 1 and had to butcher them to get it working. Now that I understand it better, I'd like to do it right. -- Dave

[Dovecot] My old email is not stored
by HylkeB 11 Apr '13

11 Apr '13

Hi, Im have not much experience with dovecot, postfix or debian, which i am using for my email server. But the thing is, everything worked just fine, until I found out that old emails were missing, only emails of a few months old exist on my server. I have no idea if this is a setting in dovecot, postfix or debian, or that something weird happened. But my question is, is there a setting in either dovecot, postfix or debian that i should check that could cause this behaviour, and if so, how do i check that? (opening and checking a conf file for example, or executing some commands in PuTTy). And if this is somehow default behaviour that cannot be changed, is there some other way to store all emails ever entered my inbox? Sincerely, Hylke Bron -- View this message in context: http://dovecot.2317879.n4.nabble.com/My-old-email-is-not-stored-tp41478.html Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Proxying, pertinent values and features, SNI
by Christian Balzer 11 Apr '13

11 Apr '13

Hello, I'm looking into deploying dovecot as a proxy, currently using perdition. Have been using dovecot on the actual servers for years, nearly a decade. So far just 1.x, but for the proxy it will have to be 2.x (2.1.7 is the current Debian version), as the trigger for this change is the need to support multiple SSL certificates. All that happens on the proxy seems to be handled by the login processes, so that is why we're not seeing anything useful in the process titles or with doveadm, right? And from past comments by Timo I guess that adding such functionality isn't on his to-do list at all. A configurable capabilities string for POP would be quite welcome, but at least nothing is different between the 1.x backends and the 2.x proxy in that protocol. Speaking of 1.x versus 2.x, the feature to pass on the remote IP from the proxy to the backend is a 2.x thing only, correct? So I suppose any parameters really affecting this setup are default_process_limit and default_client_limit as well as the settings in service-imap-login and service pop-login. In particular mail_max_userip_connections never is looked at on the proxy as this check happens in the respective protocol AFTER login, rite? I presume to best support all(?) clients out there is to have "local_name" sections for SNI first and then "local" sections for IP address based certs. It is my understanding that SNI needs to be requested by the client, so aside from client bugs (nah, those don't exist ^o^) every client should get an appropriate response for TLS. Has anybody done a setup like that already? Regards, Christian -- Christian Balzer Network/Systems Engineer chibi(a)gol.com Global OnLine Japan/Fusion Communications http://www.gol.com/

[Dovecot] [PATCH proposal] make dsync preserve pop3_uidl_format
by Mark Zealey 11 Apr '13

11 Apr '13

Hi there, I ran into an issue yesterday (dovecot 2.0) whereby when we dsync messages from a local machine (sdbox) to a remote (Maildir) which have different pop3_uidl_formats configured, the uidl format is not preserved. There doesn't seem to be any way to force this in the code, although I suspect that Maildir sources with saved pop3 uidls would pass them correctly. Attached is a rough patch against 2.0.21 dsync which will generate the uidls on the client before passing them over to the destination. This only works for %u and %v currently, also because dsync doesn't read the whole config file you need to specify -o pop3_uidl_format=... to dsync. Mark

[Dovecot] Postfix/Dovecot/lmtp with virtual and local users
by David Obando 11 Apr '13

11 Apr '13

Hi all, I'm about to change my Debian mailserver setup from Postfix/dovecot1/procmail to Postfix/dovecot2/sieve with lmtp enabled. After enabling lmtp the virtual users can receive e-mails but not the local users: Mar 21 14:21:40 orange postfix/lmtp[4119]: DE62226216: to=<user(a)orange.domain.de>, relay=orange.domain.de[private/dovecot-lmtp], delay=7627, delays=7627/0/0/0.02, dsn=5.1.1, status=bounced (host orange.domain.de[private/dovecot-lmtp] said: 550 5.1.1 <user(a)orange.domain.de> User doesn't exist: user(a)orange.domain.de (in reply to RCPT TO command)) In 10-auth.conf I have the setting "auth_username_format = %Lu". When changing it to "auth_username_format = %n" the local users can be found but not the virtual users anymore. Is there a way to define "if <user> is local then auth_username_format = %n else auth_username_format = %Lu"?

[Dovecot] Pigeonhole 0.3.4: Warning: sieve: encountered corrupt binary: re-compiling script
by Daniel Piddock 10 Apr '13

10 Apr '13

Hi all, Upgraded to Dovecot 2.1.16 and Pigeonhole 0.3.4 yesterday. We use lmtp and sieve. I've now started to see in the logs the following entries: >Warning: Jz6kNv8AY1FdfQAAVMeomg: sieve: encountered corrupt binary: re-compiling script [script path] The script then appears to run correctly and the message gets stored where ever it should be. This only appears to be happening for a few users and although it happens on the majority of their messages it doesn't happen for every single one. What's the best way to start debugging? Thank, Dan

[Dovecot] thunderbird detach attachment
by mourik jan heupink 10 Apr '13

10 Apr '13

Hi all, Thunderbird has an option to detach attachments from (for example) sent items. I've tried it, and it does not work, and also in the dovecot logs I don't see anything interesting meanwhile. Before looking deeper into this: Does anyone here know if this option is known to work, or not? We're running dovecot 2.1.7 on debian wheezy. Removing unwanted attachments is a nice way to keep mail archives smaller... Thanks, MJ

[Dovecot] How to see folders/subfolders/emails through imap
by Stephan von Krawczynski 10 Apr '13

10 Apr '13

Hello all, I am trying to do something very simple - at least thats what I thought. I have some fs, it contains folders and subfolders with email files ordered like maildir. Now I try to set up dovecot on top simply to let some imap account watch these email files. But I cannot see any folders at all. I can create new folders and see them, but I cannot create subfolders as subdirs like "folder/subfolder". Instead I get "folder.subfolder" dirs on the fs. I tried to set the separator to "/", but that does not help at all. Is there some easy way to configure dovecot to display: <somedir>/<folder1>/<subfolder1>/new/files... <subfolder2>/new/files... <subfolder3>/new/files... according to fs layout on some imap-client (like thunderbird)? -- Regards, Stephan

You probably want to compile in tcp_wrapper support and handle it that way http://wiki2.dovecot.org/LoginProcess You might also hook into a the post-login script if you need some bizarre logic to determine whether to allow a login or not, but this is later in the session setup rather than block-on-sight like a firewall. http://wiki2.dovecot.org/PostLoginScripting Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] How to exec /usr/libexec/dovecot/imap with specific maildir location

Once upon a time I could configure my mailer to access my historical archives by running something like ssh $mailserver MAIL=maildir:~/Maildir-archive dovecot --exec-mail imap I need to run /usr/libexec/dovecot/imap manually now, and I've fixed that a while ago for my normal email access. But I've just had cause to go back to my archives for the first time in a while... and realised that I don't know how to make it work any more. When invoking /usr/libexec/dovecot/imap, is there an environment variable or command line option which can set the mail location? -- dwmw2

[Dovecot] Received date on emails is wrong after file copying
by maia＠weiser.dk 09 Apr '13

09 Apr '13

Hi, I have installed a new mail server where I'm migrating from Courier to Dovecot. I have made a mistake when I was copying over the emails so the date/time mark on them is updated. So all my mails are now from the copy date/time and not the real receive time. I have tried to copy the emails over again, so they get the right date/time on the file level. And when I look at a single email in details in SquirrelMail it has now the right date/time, but when I look at the overview of a folder it still have the copy date/time on them. Is there any way to get the date/time in the overview updated, maybe delete some index files or force it to re-index? I'm not even sure that the problem is in Dovecot. But I'm sure You can help me here. Best Regards, Kim Johansen

[Dovecot] LMTP Setup/Design Help Request
by Matthias Hofer 09 Apr '13

09 Apr '13

Hi altogether, I am switching from dbmail 2.2 to dovecot 2.1.7, and I was able to do a successful transition of IMAP. But I had a very hard time with receiving mail, and in the end -- after loads of reading and debugging -- I broke down and failed. This is why I am asking you for your kind help. I only have virtual users and have set mail_uid = dovemail mail_gid = dovemail For authentication, I simply use (for now) a flat file: passdb { driver = passwd-file args = scheme=PLAIN username_format=%u /etc/dovecot/mypasswd.file } # cat /etc/dovecot/mypasswd.file user1:{PLAIN}userpw1 user2:{PLAIN}userpw2 user3:{PLAIN}userpw3 And everything works fine with IMAP. I am completely domain-agnostic here. But I was not able to use this fine setup to receive mails with my postfix. I tried about 13 different configurations, some with considerable changes dovecot-config, the passwd-file or postfix, but I could not find a single variant working. In this situation, I would be very happy if somebody could give me a hint, which would be the prudent way to configure dovecot, LDA/LMTP and postfix based on the setup above. Thank you very much in advance, and have a great time, Matthias Hofer

[Dovecot] repeating dsync - questions
by Bob Gustafson 08 Apr '13

08 Apr '13

I'm moving/converting email from one system to another The source system is: Dual core x86_64 6GB memory 180 GB raid1 disks ext4 Fedora 9 Dovecot 1.0.15 Maildir format The destination system is: Dual core x86_64 2GB memory 1TB raid1 disks ext4 Fedora 18 Dovecot 2.1.15 sdbox format I am moving mail in a series of steps: 0) cd ( to mail user home directory ) mkdir Maildir 1) # rsync mail from source system (hoho4) to current (hoho0) time rsync -arv --times hoho4:/home/bobgus/Maildir/ /home/bobgus/Maildir/ This step takes about 37 minutes the first time 2) # dsync mirror/convert to sdbox format on current system time dsync mirror maildir:~/Maildir This step takes about 858 minutes (!!) Looking at -D messages indicates that dsync is deciding between duplicates much of the time. Looking at the results in a mail browser (Evolution), it seems fine, although the latest mails are not there. 3) # pick up more current mail - use same script as in 1) time rsync -arv --times hoho4:/home/bobgus/Maildir/ /home/bobgus/Maildir/ This step takes about 5 minutes although this varies depending on the amount of new mail. 4) # repeat the 2) dsync step time dsync mirror maildir:~/Maildir This is where things look peculiar. When I look at the directory of sdbox/mailboxes, I see duplicated directories [bobgus@hoho0 sdbox]$ cd mailboxes [bobgus@hoho0 mailboxes]$ ls Apple Mail To Do Apple Mail To Do_2a47983780615e5179600000ba55d82c Deleted Messages Deleted Messages_2847983780615e5179600000ba55d82c Drafts Drafts_2447983780615e5179600000ba55d82c Important Important_2947983780615e5179600000ba55d82c INBOX INBOX_1547983780615e5179600000ba55d82c Sent Sent_2547983780615e5179600000ba55d82c Trash Trash_2747983780615e5179600000ba55d82c The 2nd dsync step has not completed yet. I'm wondering whether the extra directory will be magically moved into the older directory. (This is unlikely because the file names are duplicated in the new directory) ------- Is this expected behavior? Are there command changes I can make to speed up the process? Eliminate the duplicate directories?

Hi, I am trying to use separate configurations for ldap authentication thus providing users with the ability to only use username without domain part. Now according to documentation this should be possible http://wiki2.dovecot.org/AuthDatabase/PasswdFile but I keep getting error in my dovecot.log like this auth: Error: Can't open configuration file /etc/dovecot/%l/dovecot-ldap.conf: No such file or directory Why does dovecot does not expand %l to local ip address?

[Dovecot] dsync replication: quota counted twice
by Oli Schacher 08 Apr '13

08 Apr '13

Hi I enabled quota + warnings in my replication test setup and now whenever a mail gets delivered the quota is counted twice (probably due to both servers using the same mysql quota backend) and quota warnings are fired too early. After a doveadm quota recalc -u <username> the quota is correct again. How do I make dovecot only count the quota on the server where the mail was added originally? dovecot -n is the same as in my previous message to the list today http://www.dovecot.org/list/dovecot/2013-April/089558.html (thanks Timo for the hint in this thread btw, changing the permissions made the errors go away) Thanks Oli -- message transmitted on 100% recycled electrons

[Dovecot] Dovecot Configuration
by Andreas K. 08 Apr '13

08 Apr '13

Can somebody, please, point me in the right direction in finding a COMPLETE and EXACT definition of the Dovecot configuration hierarchy. In other words what configuration options exist both at the top level but also at each subconfiguration elements (ex. sections etc). While my C is a bit rusty, I can still make sense of source code and with a bit of effort I will figure it out. I have been going through the src/config/all-settings.c but still have large gaps. A hint in the right direction on how the config works might help clarify and speed things up. Thanks Andreas Kasenides

[Dovecot] Problem with fts lucene, on solaris 10

[Dovecot] checkpassword protocol
by dovecot.pkoch＠dfgh.net 08 Apr '13

08 Apr '13

Hi, I'm writing a checkpassword script in order to support our OTP token as a fallback for client certificate authentication. Here are two questions: 1) It seems to me that the username and the password will be delivered to my script both on file descriptor 3 and via the environment variables AUTH_USER and AUTH_PASSWORD. May I ignore file descriptor 3 and use the environment variables or may it happen that these variables will have differnet content from what is sent via fd 3? 2) There seems to be some undocumented interaction between dovecot and my script via file descriptor 4. Seems that whatever I write to fd 4 will show up in syslog (unless it contains newlines). Can I use this "feature" to send error messages from my script to dovecot? What data does dovecot expect on fd 4? Peter

[Dovecot] ssl_require_crl does not work as expected
by dovecot.pkoch＠dfgh.net 08 Apr '13

08 Apr '13

Hi I'm trying to use dovecot with client certificates. We produce our certificates with our on CA and we do NOT use certificate revocation lists. So I put "ssl_require_crl = no" into 10-ssl.conf. I did not find a solution neither in the wiki nor somewhere else, so I finally started to read the source. My impression is that openssl will always try to use CRLs. If "ssl_require_crl = no" dovecot will use CRLs but tries to ignore openssl error codes X509_V_ERR_UNABLE_TO_GET_CRL and X509_V_ERR_CRL_HAS_EXPIRED. This is done in ssl_verify_client_cert() in ssl-proxy-openssl.c line 871, namely i_info("proxy=%d, require_crl=%d, error=%d", proxy->client_proxy, proxy->set->ssl_require_crl, ctx->error ); if (proxy->client_proxy && !proxy->set->ssl_require_crl && (ctx->error == X509_V_ERR_UNABLE_TO_GET_CRL || ctx->error == X509_V_ERR_CRL_HAS_EXPIRED)) { /* no CRL given with the CA list. don't worry about it. */ preverify_ok = 1; } With my setup proxy->client_proxy is 0. I added the i_info() to check this and with this modification my syslog shows: Apr 7 13:01:16 d600 dovecot: master: Dovecot v2.1.15 starting up (core dumps disabled) Apr 7 13:01:21 d600 dovecot: auth: Debug: Loading modules from directory: /usr/dovecot/lib/dovecot/auth Apr 7 13:01:21 d600 dovecot: auth: Debug: auth client connected (pid=26175) Apr 7 13:01:22 d600 dovecot: imap-login: proxy=0, require_crl=0, error=3 Apr 7 13:01:22 d600 dovecot: imap-login: Invalid certificate: unable to get certificate CRL: /CN=...user cert.../C=DE Apr 7 13:01:22 d600 dovecot: imap-login: proxy=0, require_crl=0, error=3 Apr 7 13:01:22 d600 dovecot: imap-login: Invalid certificate: unable to get certificate CRL: /CN=...intermedieate cert.../C=DE Apr 7 13:01:22 d600 dovecot: imap-login: proxy=0, require_crl=0, error=3 Apr 7 13:01:22 d600 dovecot: imap-login: Invalid certificate: unable to get certificate CRL: /CN=Root-CA.../C=DE I dont know what the proxy-stuff is about so instead of ignoring CRL-related errors I tried to disable CRL-checking. I therefore commented out two lines in ssl_proxy_ctx_verify_client() in ssl-proxy-openssl.c line 1004, namely: // X509_STORE_set_flags(store, X509_V_FLAG_CRL_CHECK | // X509_V_FLAG_CRL_CHECK_ALL); This tells OpenSSL not to check CRLs. Of course in production code this should be done only if "ssl_require_crl = no". Similar code is contained in iostream-openssl-context.c, namely in routine ssl_iostream_ctx_verify_remote_cert() Is this a bug? Peter

[Dovecot] client limit and STARTTLS
by David Benfell 08 Apr '13

08 Apr '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, I'm migrating from one system to another. Both are Arch Linux, but copying the configurations and just modifying them for IP addresses and hostnames didn't work. Here's doveconf -n # 2.1.15: /etc/dovecot/dovecot.conf doveconf: Warning: service auth { client_limit=256 } is lower than required under max. load (3072) doveconf: Warning: service anvil { client_limit=256 } is lower than required under max. load (2051) # OS: Linux 3.8.4-1-ARCH x86_64 base_dir = /var/run/dovecot/ default_client_limit = 256 default_process_limit = 1024 login_trusted_networks = 10.8.0.0/16 127.0.0.0/8 mail_location = maildir:~/Maildir mail_max_userip_connections = 30 passdb { args = failure_show_msg=yes driver = pam } service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } } ssl_cert = </big/www/ssl/www.cybernude.org_publickey.pem ssl_key = </big/www/ssl/www.cybernude.org_privatekey.pem userdb { driver = passwd } Obvious first question: I can't figure out how to make dovecot happy with the client and process limits. I'm not terribly worried about going overboard here, though I have a very small number of users; the migration is to a much more capable system. But I would like to stop looking at the warning. It doesn't seem to matter what I put where--it keeps complaining. Second question: STARTTLS isn't working. What am I missing? Sorry if this is something that should be obvious; I'm fighting a similar battle with postfix and I'm being pushed around the bend while I really need to be working on other things.

[Dovecot] v2.2.rc6 released
by Timo Sirainen 08 Apr '13

08 Apr '13

http://dovecot.org/releases/2.2/rc/dovecot-2.2.rc6.tar.gz http://dovecot.org/releases/2.2/rc/dovecot-2.2.rc6.tar.gz.sig Some more fixes to bugs I noticed today while trying out some new things in production. Note especially the replicator-doveadm socket change, see http://wiki2.dovecot.org/Replication for how to configure it. This change allowed local replicator to notify the remote replicator about user being synced. * replicator: Don't create replicator-doveadm socket by default. This way doveadm replicator commands don't accidentally start an unconfigured replicator server. + replicator: Have remote dsync notify the remote replicator that a user was just synced. This way the replicators are kept roughly in sync. + Added ssl_client_ca_file to specify the CA certs as a file. This is needed (instead of ssl_client_ca_dir) in RedHat-based systems. + Added "doveadm fs" commands, mainly to debug lib-fs backends. - Mailbox list indexes weren't using proper file permissions based on the root directory.

[Dovecot] mdbox and folders containing both messages and sub-folders
by Rich Wales 08 Apr '13

08 Apr '13

I've got Dovecot 2.2r5 (Ubuntu package version 2:2.2.0~rc5-0~auto+1 from the "testing-auto/dovecot-2.2" repository on xi.rename-it.nl) running on a brand-new Ubuntu 12.04.2 server. I'm trying to configure Dovecot (using the "mdbox" mailbox format) to allow folders to contain both messages and sub-folders. However, it's not working consistently. I need to have folders with both messages and sub-folders because I'm trying to migrate mail from an existing (but soon-to-be-retired) Cyrus server, and the existing body of mail has folders of this sort. I'm currently using the following configuration line: mail_location = mdbox:~/mdbox:DIRNAME=.indexes:INDEX=~/mdbox/indexes and am using the Larch program to do an IMAP-to-IMAP copy of one of my family member's mail from the old Cyrus server to the new Dovecot server. When I examine the "mailboxes" directory tree, I see some directories that (correctly) contain both the renamed ".indexes" directory and also directories for IMAP subfolders. However, the Larch output is showing many errors of the form "mailbox cannot contain messages", and some of the messages could not be migrated because of this problem. Am I doing something wrong? Or is the "folders containing both messages and sub-folders" feature simply broken for the "mdbox" format -- meaning presumably that I'll be forced either to use the Maildir format, or else abandon Dovecot entirely and install Cyrus on my new mail server instead?

[Dovecot] autocreate mailbox but no sub folders
by Arnaud Abélard 08 Apr '13

08 Apr '13

Hello, We have been using lda_mailbox_autocreate to avoid to intialize empty mailboxes upon account creations. This does the job allright except that dovecot-lda is also allowed to autocreate sub folders which is a problem when using addresses extensions (adress+folder(a)domain.tld) It's easy for a malicious user to flood a mailbox with tons of subfolders. Is there a way to tell dovecot-lda it can only create the initial mailbox and maybe some special folders but nothing else?

[Dovecot] replicator/dsync over tcp
by Michael Grimm 08 Apr '13

08 Apr '13

Hi -- I am testing replicator/dsync over tcp, and I did run into some issues. First of all I did need to extend http://wiki2.dovecot.org/Replication to get dsync over tcp running without ssl: | # dsync over tcp default port | # | doveadm_port = 12345 | service doveadm { | # running dsync over tcp and using ssl | # added-->| user = vmail | inet_listener { added-->| address = 1.2.3.4 | port = 12345 | # ssl = yes | } | } | plugin { | # this host replicates to remote host | # | mail_replica = tcp:SERVER-A.TLD That didn't work ... | dovecot: doveadm(test): Error: doveadm_password not set, can't authenticate to remote server ... thus, I needed to add: added-->| local 1.2.3.4 { added-->| # password for client authentication by doveadm server added-->| # added-->| doveadm_password = secret added-->| # allow client to only use specified list of commands (default is all): added-->| # added-->| #doveadm_allowed_commands = added-->| } 1. Question: may one include "secret" from a file? Well, that runs like a charm! Now, I did try to add ssl by activating "ssl = yes" in 'service doveadm' (see above) and adding ... | # used by replicator/dsync over tcp | # | ssl_client_ca_dir = /<path-to>/ssl/certs ... and ... | mail_replica = tcps:SERVER-A.TLD But, this didn't work (logfile at remote server): | dovecot: doveadm(test): Invalid certificate: self signed certificate: /OU=dovecot server/CN=OTHER-NAME.TLD/emailAddress=postmaster(a)OTHER-NAME.TLD | dovecot: doveadm(test): Error: SERVER-A.TLD: Received invalid SSL certificate | dovecot: doveadm(test): Error: sync: Disconnected from remote The OTHER-NAME.TLD is served by my additional settings used by my MUAs: | ssl_cert = </<path-to>/ssl/certs/OTHER-NAME.TLD.pem | ssl_key = </<path-to>/ssl/private/OTHER-NAME.TLD.pem I did supply SERVER-A.TLD certs and private certificates at both servers as well, but dovecot seems to use those of OTHER-NAME.TLD for replicator/dsync instead :-( 2. Question: May I config the certificate that should be used for replicator/dsync and that might be different from those used by my MUAs (other then pointing to '/<path-to>/ssl/certs')? I am quite sure that I screwed my config somehow, but I cannot find the cause. Thus, someone? Thanks, and with kind regards, Michael

I had no idea that was how it worked.

This loses much of the security benefits of the login process design, because in case of a security hole (in Dovecot or SSL library) the attacker is now able to see other users logging in and steal their passwords, read their mails, etc. Default client_limit * process_limit = 1000*100 = 100k connections vsz_limit should be increased to avoid out of memory errors, especially if you're using SSL/TLS.

[Dovecot] The sieve_extprograms plugin included in main Pigeonhole 0.4 source tree
by Stephan Bosch 07 Apr '13

07 Apr '13

Hi, I think the sieve_extprograms is mature enough for an initial release and that is why I've included the sieve_extprograms plugin into the main Pigeonhole v0.4 source tree. It is still a plugin, but is no longer provided as a separate package. This should make things easier. It will be released along with Pigeonhole v0.4.0. Regards, Stephan.

[Dovecot] Released Pigeonhole v0.3.4 for Dovecot v2.1.16
by Stephan Bosch 06 Apr '13

06 Apr '13

Hello Dovecot users, Much time passed since I last released a new Pigeonhole, so quite a few unreleased fixes were pending until now. Development of new features is shifted to the upcoming Pigeonhole v0.4 for Dovecot v2.2. I intend to release v0.4.0 shortly after Dovecot v2.2.0. Changelog v0.3.4: * Changed error handling to be less of a nuisance for administrators. Strictly user-caused errors are only reported in user log. Some errors are logged as info instead. * Sieve: Changed behavior of redirect in case of a duplicate message delivery or a mail loop. If a duplicate is detected the implicit keep is canceled, as though the redirect was successful. This prevents getting local deliveries. The original SMTP recipient is used when it is available to augment the entry in the LDA duplicate database. This way, duplicates are only detected when (initially) addressed to the same recipient. + Sieve vnd.dovecot.duplicate extension: added new features to the duplicate test, making it possible to manually compose the key value for duplicate checking. This extension is in the process of being standardized: https://tools.ietf.org/html/draft-bosch-sieve-duplicate-01 + Sieve date extension: generate warning when invalid date part is specified. - Sieve editheader extension: fixed crash occurring when addheader :last was used. - Sieve include extension: fixed missing error cleanup that caused a resource leak. - Sieve vacation extension: fixed determination of From: address for when sieve_vacation_dont_check_recipient is active. - Sieve tools: the -D option wasn't enabled and documented for all tools. - Sieve dict script storage: fixed potential segfault occurring when dict initialization fails. - ManageSieve: fixed bug in skipping of CRLF at end of AUTHENTICATE command. - ManageSieve: fixed handling of unknown commands pre-login. - Fixed compile on Mageia Linux. The release is available as follows: http://www.rename-it.nl/dovecot/2.1/dovecot-2.1-pigeonhole-0.3.4.tar.gz http://www.rename-it.nl/dovecot/2.1/dovecot-2.1-pigeonhole-0.3.4.tar.gz.sig Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] password encryption
by Jim Pazarena 06 Apr '13

06 Apr '13

I have just come to the realization that password encryption using the crypt function in linux, ONLY USES THE FIRST 8 CHARS. I have written routines using crypt allowing 16+ chars, and find that anything past 8 is ignored. Wow. Is there a way around this that can be used in dovecot, as well as encryption routines for an email front end? (not system users). It's the integration with dovecot which is the most important.

[Dovecot] not showing subfolders on INBOX

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, Apologies if a duplicate message. I initially sent the following from a non-subscribed email address (my usual address, but not the one that works when I'm having trouble with mail). First, I'm pretty sure I screwed up something with dovecot. The symptom appears in both thunderbird and mutt. I'm moving my server from a VPS to a dedicated server. *Both* are Arch Linux systems. Here's the dovecot -n output: # 2.1.15: /etc/dovecot/dovecot.conf # OS: Linux 3.8.4-1-ARCH x86_64 base_dir = /var/run/dovecot/ default_client_limit = 3000 default_process_limit = 1000 login_trusted_networks = 10.8.0.0/16 127.0.0.0/8 mail_location = maildir:~/Maildir mail_max_userip_connections = 30 passdb { args = failure_show_msg=yes driver = pam } service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } } ssl_cert = </home/www/ssl/www.cybernude.org_publickey-apache.pem ssl_key = </home/www/ssl/www.cybernude.org_privatekey.pem userdb { driver = passwd } One detail, the kernel version, is different from what is indicated above. munich is the new system; atlanta is the old one: Linux munich.parts-unknown.org 3.8.4-1-ARCH #1 SMP PREEMPT Wed Mar 20 22:10:25 CET 2013 x86_64 GNU/Linux Linux atlanta.parts-unknown.org 3.6.10-1-ARCH #1 SMP PREEMPT Tue Dec 11 09:40:17 CET 2012 x86_64 GNU/Linux I literally copied this configuration, so it's the same on both systems. But on the new system, I'm not seeing subfolders in INBOX. I also copied my Maildir from the old system to the new system, so it should--I thought, anyway--be okay. What did I do wrong?

http://dovecot.org/releases/2.2/rc/dovecot-2.2.rc4.tar.gz http://dovecot.org/releases/2.2/rc/dovecot-2.2.rc4.tar.gz.sig A lot of small random fixes. Some last minute major cleanups/fixes to lib-http and lib-ssl-iostream error handling, which makes them much easier to debug if something goes wrong (so e.g. if https site has invalid certificate, the caller gets error message saying that, including the part of the cert that couldn't be validated). I don't have anything important left in my v2.2 TODO. It passes all my tests. So I'm hoping for v2.2.0 release any day now. + Added "doveadm replicator" commands - Larger changes to lib-http and lib-ssl-iostream error handling. The API caller can now get the exact error message as a string. - Various bugfixes to LDAP changes in rc3

[Dovecot] Outlook 2013 - mounting folders with XLIST
by Hajo Locke 04 Apr '13

04 Apr '13

Hello, i do some tests with dovecot 2.1.7 and activated a default special-use config. To get it work with outlook 2013, i also added XLIST to imap capability string. basically this is working. is somebody also using special-use folders successful with outlook 2013? In my understanding of special-use extension, every client should map its own local folders to corresponding folders on server. Real Name of folder on server should be irrelevant, if a folder "aaa" is marked as \Sent, then a Client should show this folder as "Sent" "Sent Items" or "Gesendete Objekte", just like local preferences. Outlook 2013 seems to work slightly different. Outlook 2013 seems to really use the marked folder on server regardless of local preferences. If i mark Drafts as \Drafts, outlook 2013 will use this for drafts even in german environment. Did somebody other notice this behaviour? Is it possible to adjust some settings in outlook 2013 fo fix this? Otherwise the serveradmin is forced to provide special-use folders per every single user and let them choose how his folders should be named? What experience did others make who use special-use folders in productive environment? Thanks, Hajo

[Dovecot] maildirsize problem
by mastertoilet＠netzero.net 04 Apr '13

04 Apr '13

i am currently using roundcube my webmail and configure using dovecot quota plugins. but it seems to not be updating the maildirsize when new mails comes.Deleting the maildirsize will recreate the files correctly.Is there any solutions to this problem with dovecot. Either you're not using dovecot-lda to deliver the mails, or you haven't configured quota plugin correctly for it. dovecot -n output and logs about a mail delivery would help. My configuration is using Centos 6.dovecot 2.1.1.and i have configure the quota plugin.but i am not sure what you mean by dovecot-lda.i just follow the guides on the internet and skim through dovecots documentation.i am using the local unix account for mail account not using virtual users.here is my configuration: [root@mail ~]# dovecot -n # 2.1.1: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-279.el6.x86_64 x86_64 CentOS release 6.3 (Final) base_dir = /var/run/dovecot/ mail_debug = yes mail_location = maildir:~/Maildir mail_plugins = " quota" maildir_broken_filename_sizes = yes mbox_write_locks = fcntl 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 } plugin { quota = maildir:User quota quota_rule = *:storage=1G quota_rule2 = Trash:storage=+100M } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } } ssl = required ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } protocol imap { imap_id_log = * imap_idle_notify_interval = 2 mins mail_plugins = " quota imap_quota" } protocol pop3 { mail_plugins = " quota imap_quota" } i am still not sure why maildirsize is not updating.thanks ____________________________________________________________ How to Sleep Like a Rock Obey this one natural trick to fall asleep and stay asleep all night. http://thirdpartyoffers.netzero.net/TGL3231/515ce5588c8f765586e9dst01duc

[Dovecot] sieve-filter ignoring separator
by Isak Rubin 03 Apr '13

03 Apr '13

It seems like running sieve-filter from the console ignores the separator setting, thus not letting me filter into folder names containing dots. Normal delivery using lda handles it just fine, but not when using the sieve-filter command. Character not allowed in mailbox name: '.' Is there anyway to override this or is patching and recompiling the source my only option? # dovecot --version 2.1.9 /Isak

[Dovecot] Sieve vacation issue - Dovecot + Postfix + LDA
by Ivan Bogdanovic 03 Apr '13

03 Apr '13

Hi to all, I have an issue with Dovecot Sieve on sending vacation message... Actually Sieve is working and I can use all the filters but just vacation is causing a problem and only in specific case... I have Dovecot + Postfix + LDA running on Ubuntu 11 without MySql database for users but I'm using virtusertable instead. The problem is when linux user ( mail user ) is different from mail allias in virtusertable... Example: ivan(a)domain.com > ivan1 ( from virtusertable ). When alias and user are the same sieve vacation works just fine but when it's not the sieve script collects the user(ivan1)(a)domain.com in from instead ivan(a)domain.com and this is when mail log shows like "discarded message because of implicitily no known envelope in message header etc... Is there a way to adjust sieve to pickup the recipient address from mail header or whatever and not to collect the user...? I was trying to play with postfix master.cf using dovecot-lda switches -f ${sender} -a (or -d ) ${recipient} but without success... Did anyone had this kind of problem? I would really appreciate some hints on fixing this issue... Thanks, Ivan

[Dovecot] Separate log file for Sieve
by Ewald Dieterich 03 Apr '13

03 Apr '13

I use log_path = /var/log/dovecot/error.log info_log_path = /var/log/dovecot/info.log debug_log_path = /var/log/dovecot/debug.log to log to different files. Since I don't consider Sieve errors as severe as "real" Dovecot errors I would like to keep them away from the error log. Is it possible to configure a separate log file for Sieve?

[Dovecot] (no subject)
by Walter Steiner 02 Apr '13

02 Apr '13

I've run into a problem with `doveadm backup` (2.2 rc2 and 20130226) I did not notice in 2.1.15 doveadm backup [-Dv] -R -u cyrtest1(a)iai.uni-bonn.de -m INBOX imapc: => crashes (signal 6 with acl plugin configured, sig 11 without acl) If this is considered a bug (not just because of the crash but in the meaning of "my configuration should work") it would be great if it could be fixed.;-) If I can provide more detail (log, gdb bt full and doveconf -n follow the next paragraph) or test something I would be happy to to so. As I'm planning dsync replication of the two backends I thought it would be better to start things with the upcoming new dovecot 2.2 (dsync protocol) instead of 2.1.15. (?!) --- first some information about what I'm trying to do --- We want to replace our single cyrus 2.4 server with two backend servers (separate storage and all user mailboxes etc. each) Even if cyrus-to-cyrus should be much easier _and_ time is slipping away I want to take this one opportunity to switch to dovecot if possible. - Thank you very much for your great work on dovecot and all the efforts! - We want the IMAP clients to continue using their folders/messages etc so I want to reproduce the "cyrus structure" we are using for the last 14 years: - own user folders: INBOX and INBOX.subfolder ... - (if possible: other user folders: user.otheruser...) - converting as much as possible of existing data To get the folders/messages into the new dovecot server(s) I'm thinking about some repeated "doveadm mirror / backup -R ... imapc:" runs while the cyrus server is still in use. The first sync run will take several days but a few more and the time will be short enough to do the complete switch-over w/o surprises. Insertion: I played with 2.1.15 and namespaces but maybe I did not understand this well enough: doveadm backup -R -u userx [w or w/o -m INBOX and/or -n INBOX] imapc: => if cyrus userx has permissions on other users mailboxes these folders are also copied. ... copied _into_ the INBOX of (dovecot) userx. I too got the known problems with INBOX.INBOX. paths. I changed dsync-brain.c sources to skip "^user." folders and to cut the additional "INBOX." => seems okay... messages (only the expected) got transferred! --- To see if things still work as with 2.1.15 (no dsync source modification!) I did (as before with 2.1.15): doveadm backup [-Dv] -R -u cyrtest1(a)iai.uni-bonn.de -m INBOX imapc: => but it crashes (signal 6) doveadm(cyrtest1(a)iai.uni-bonn.de): Debug: auth input:

[Dovecot] Dovecot 2.2rc3 Client Cert Auth and Webmail -> auth_ssl_require_client_cert problem
by Christian Felsing 31 Mar '13

31 Mar '13

Hello, I would like to set up a Dovecot based mail system which uses X.509 Client Certificates for authentication. A webmail system based on Horde5 should use Dovecot as backend. For now Dovecot works with client certificates issued by my CA and Horde authenticates also with same client certs. Due to protocol it is impossible to use client certs presented by user to Horde for authentication at Dovecot, so Horde should be allowed to authenticate itself without or an arbitrary password to Dovecot. Horde and Dovecot are running in same protected LAN. Unfortunately Dovecot does not support different authentication methods on different IP addresses or ports. This does not work: remote 192.168.116.28/32 { auth_ssl_require_client_cert = no auth_ssl_username_from_cert = yes disable_plaintext_auth = no ssl = yes } Result is "doveconf: Fatal: Error in configuration file /opt/dovecot-2.2.rc3/etc/dovecot/conf.d/10-auth.conf line 103: Auth settings not supported inside local/remote blocks: auth_ssl_require_client_cert" Replacing "auth_ssl_require_client_cert = no" by "ssl_verify_client_cert = no" does not yield in an error, but it does nothing, Dovecot still insists for a client certificate. I afraid that I am trapped by this problem: http://dovecot.2317879.n4.nabble.com/Problem-with-requiring-client-certific… Is there any way to turn off client certs for specific local or remote IP addresses? best regards Christian

[Dovecot] Incorrect response when opening read-only mailboxes with per-user flags?
by Guido Berhoerster 31 Mar '13

31 Mar '13

After some debugging on the protocol level I've finally found the problem with per-user seen flags in read-only mailboxes. Dovecot actually does allow storing the seen flag on messages but AFAICS it does not communicate that correctly to clients, this is what its response to selecting a read-only mailbox with "lrs" ACL in effect for the logged in user looks like: 2 SELECT "Public/Test" * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS ()] Read-only mailbox. * 2 EXISTS * 0 RECENT * OK [UNSEEN 2] First unseen. * OK [UIDVALIDITY 1364221612] UIDs valid * OK [UIDNEXT 3] Predicted next UID * OK [HIGHESTMODSEQ 1] Highest 2 OK [READ-ONLY] Select completed. Shouldn't PERMANENTFLAGS contain \Seen here if per-user seen flags are enable and should it even be tagged READ-ONLY at all in this case? At least clients such as Python imaplib, IMAPClient, or Roundcube will open such mailboxes with EXAMINE and thus do not allow the modification of flags. -- Guido Berhoerster

[Dovecot] dsync mirror to convert from mbox (1.2x) to mdbox (2.2)
by Ken A 31 Mar '13

31 Mar '13

I'm converting mail from mbox to mdbox. I've copied mail over to a new system, and now I'm running dsync like this: dsync -u username mirror mbox:/folder_location/username:INBOX=/inbox_location/username That seemed to work, with a couple minor errors: > dsync(username): Warning: Our dotlock file /mail_location/username.lock was deleted (locked 20 secs ago, touched 20 secs ago) > dsync(username): Error: file_dotlock_delete() failed with mbox file /mail_location/username: No such file or directory Do I also need to specify where dovecot's indexes are for the old mbox files, or is this not needed for mbox conversions (when they are the source)? Thanks, Ken A.

[Dovecot] Dovecot METADATA support
by Bruce Marriner 31 Mar '13

31 Mar '13

I've been trying to work with dovecot metadata plugin and posted a question here related to that a few days ago here : http://www.dovecot.org/list/dovecot/2013-March/089241.html I just read today (e-mail on this list) from Timo Sirainen that >> >> Dovecot is getting close to having native METADATA support. >> I am very curious about this. When is "getting close" and I would guess this will be for v2.2? Will this support be the same as the dovecot-metadata-plugin in hg or something completely different? I'm sorry if I'm asking questions that have already been answered. My goal is to use Kolab3 with Dovecot instead of using Cyrus IMAP and Kolab requires metadata/annotation support. Right now I'm testing this using the dovecot-metadata-plugin but I am very interested it learning about native metadata support and testing it with Kolab 3. Any detail you can provide would be very appreciated. Bruce

[Dovecot] global mail_plugins

Hello! How do I know what is specified in the global mail_plugins? # doveconf |grep mail_plugins mail_plugins = mail_plugins = " quota sieve" mail_plugins = " quota imap_quota autocreate" mail_plugins = " sieve" Is it just what is defined in the dovecot.conf and when there is nothing defined there are no global mail_plugins per default?

[Dovecot] Cassandra support

Hi, I've read some previous threads about Cassandra support. In a message at April 2012 it was written that it would take a few hours after doing some internal stuff. http://dovecot.markmail.org/search/?q=cassandra#query:cassandra%20order%3Ad… I wonder if there have been a progress since then? Or a better alternative came up? -- Goktug

[Dovecot] Custom Headers/Flags Support in dovecot
by Ramesh Natarajan 31 Mar '13

31 Mar '13

I am currently trying to evaluate if I can use dovecot to be used for my imap server like application. This is not an email application but a generic storage server that uses IMAP protocol to save and retrieve messages. The messages have standard From/To/Date headers and a lot of custom headers for threading conversations e.t.c. As a part of my application requirements I also need to support custom flags and have ability to set/change/retrieve them via IMAP. 1) Does Dovecot support custom flags to be set/changed/retrieved? 2) I understand dovecot optimizes standard RFC822 headers and flags in cache/index files for faster lookups and searches. Does custom headers and flags fall into this optimization algorithm? 3) I am planning to support multiple users and each mailbox may have upto 1000 folders. Each folder may have an average of 20 MIME encoded messages. I am planning to use local storage with single-dbox format. Do you see any issues with this? thanks Ramesh

[Dovecot] Conversion from Evolution maildir to imap
by Paul van der Vlis 31 Mar '13

31 Mar '13

Hello, A customer has a thin-client server with 100+ homedirs with Evolution. They are using POP3 and maildir. Now I want to switch to IMAP. Can I use Dovecot on this maildirs, or does Evolution use another kind of maildir? Does Dovecot change anything in the maildirs? Do I loose my flags this way, like "read" ? Normally I am using Cyrus IMAP. What I want to do is to install Dovecot to have access to the mail over IMAP because Dovecot can do maildir (Cyrus cannot). Then I can use imapsync to sync everything to Cyrus. Do you think that's a good idea? With regards, Paul van der Vlis. -- Paul van der Vlis Linux systeembeheer, Groningen http://www.vandervlis.nl/

[Dovecot] Managesieve Automatic Homedir Creation: File not Found Error
by linuxer＠netsteps.ch 31 Mar '13

31 Mar '13

Hi all, I'm running dovecot version 2.0.19 (Ubuntu 12.04) and I discovered some unexpected behaviour related to the Dovecot managesieve module. When connecting to the managesieve service from a client for the first time (e.g. roundcube webmail), I get an application error. This is logged by Dovecot: Error: sieve-storage: opendir(/var/.../exampledomain/exampleuser@exampledomain//sieve) failed: No such file or directory. At first glance I thought the problem was caused by the "//" in the directory path. I assume this is just a concatenation of the user virtual home directory (in my case "/var/.../exampledomain/exampleuser@exampledomain/" and the default sieve folder (~/sieve). While this looks wrong it seems not to be the actual problem (should be fixed though?) Then I noticed that the user home directory and sieve data were actually properly created despite the error. When connecting again, it worked without error. The problem can be reproduced by deleting the users virtual home directory and connecting again. A guess would be that the automatic creation of the virtual users homedir folder structure is some asychronous process not being completed in time. I also found this older thread with a similar issue: http://osdir.com/ml/dovecot-development/2010-05/msg00018.html Could also be worth mentioning that I'm running Dovecot on a virtualized host with possibly relatively poor I/O performance (maybe faster environments don't have this problem). Thanks for looking into this, and thx for the really neat dovecot software package! Cheers, L.

[Dovecot] ACL for root-level mailboxes
by Bradley Rintoul 31 Mar '13

31 Mar '13

Hello: I see in the documentation where it says that if mailboxes are created at the root level it will use the namespace's default ACL. I'm using Dovecot 2.0.9 so there is no default namespace defined, so I'm a bit handicapped here... Anyway, assuming I can figure out how to define a default namespace, how do I specify its ACL? Where would the file describing the access go? Sorry if this is a bit broad, but any help would be appreciated. Thanks, B. Rintoul

[Dovecot] 3 node setup without cluster filesystem
by Michael 30 Mar '13

30 Mar '13

Hi everyone, short version: Is there any 3 host (two MX and one frontend IMAP) that can use a shared (iSCSI) ext4 volume? Long version: I am running a very complex setup right now with two MX, two proxies(lmtp/imap)/imap-frontends and two backends mounting an ocfs2 volume. I would like to reduce the complexity (and the number of hosts) and get rid of ocfs2. I ask myself if I can use an ext4 iSCSI-LUN using this setup: MX01 -> lmtp:unix:private/dovecot-lmtp -> mail_home: /var/mail MX02 -> lmtp:unix:private/dovecot-lmtp -> mail_home: /var/mail IMAP01 (imap) -> mail_home: /var/mail Regards Michael

[Dovecot] Gmail like labels, three years later
by Pablo Vieira 27 Mar '13

27 Mar '13

On this post http://www.dovecot.org/list/dovecot/2011-June/059605.html I was asking about the possibility of using arbitrary labels on messages, much like Gmail does. On following replies, I was told about few tricks that might be used, that the IMAP protocol was being considering UTF-8 labels and ways to integrate them into the current system, etc., etc., etc. That sounds nice and all. I'm chiming in three years later only to know if things have changed, both at Dovecot and at the IMAP protocol. Are we closer to have proper labels on IMAP? Labels that help sorting messages in virtual folders where a message can belong in several of them? I consider "label vs folder" a done discussion (since labels can always include folders; a labels system can always be implemented as a folders system, but not viceversa; etc), so what's stopping development in that direction? Have any new energies being devoted to that cause? I just seen Dovecot is number 1 among IMAP servers by a large margin. Congratulations to the devs. Aleve.

Furthermore, it doesn't need the userdb prefetch. Summarizing, the minimal incantation for passing dovecot variables to the post-login script is userdb { driver = passwd-file args = /var/dovecot/test/passwd default_fields = pw=%w } service imap { executable = imap postlogin ... } service pop3 { executable = imap postlogin ... } service postlogin { executable = script-login /path/to/postlogin-exec # Careful -- defaults to root user = $default_internal_user unix_listener postlogin { } } I've updated the Dovecot2 wiki, but I am unsure which userdb's "default_fields" applies to, and whether it just applies to postlogin scripts, so I documented it at http://wiki2.dovecot.org/AuthDatabase/PasswdFile Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Problem when indexing maildir with a large number of folders
by Andre Rodier 27 Mar '13

27 Mar '13

Hello everybody, As part of a migration from exchange 2003 to dovecot, I have converted a lot of PST files for a user. I am importing his PST files in a maildir folder called 'Archives'. Actually, I reached about 770 'Archives' folders, and the total length of their names is about 59k characters. Thanks to wc! I am using Maildir++ I can run the doveadm index command on the private namespace, however, I am not able to do this on the virtual folders.

[Dovecot] Implementing Single instance attachment storage (SIS) with sdbox
by megodin＠inboxalias.com 27 Mar '13

27 Mar '13

Hi there, as I want to implement data dedupliction on my dovecot system (eg. a users sends the same attchment to 5 different users on my system so I only have to store the attachment one time and set pointers to the file) , I found out it could be possible with Single instance attachment storage (SIS), so I read several pages about SIS as it was quoted here (http://wiki2.dovecot.org/MailboxFormat/dbox) > dbox storage is extensible. Single instance attachment storage was already implemented as such extension. But I did not found any further intructions in Dovecot Wiki how to implement it - however, on Dovecots blog there was an older article from Timo which gave some indication how to get it work (http://blog.dovecot.org/2010/07/single-instance-attachment-storage.html) > mail_location = dbox:~/dbox:ATTACHMENTS=/attachments/$/$ But when I change my configuration according to this (I use sdbox as mail format), I just get a "Unknown setting: ATTACHMENTS" in my mail.err log. Can anybody give me a clue how to get this working? Thanks in advance! Megodin --- Alle PostfÃ¤cher an einem Ort.

[Dovecot] Sieve Vacation for redirected email
by Dave Gattis 27 Mar '13

27 Mar '13

I posted this elsewhere, but under an old post. I apologize for the repeated question. Hello Dovecot Users, Dovecot 2.1.7 Our emails are redirected from the home office causing all vacation responses to fail with, "discarding vacation response for implicitly delivered message; no known (envelope) recipient address found in message headers". I need to use the Sieve Vacation option but cannot figure out how to get it working for us. If I send to the local address, it works fine. If I send to the redirect address, it fails with above error. Unfortunately, all of our emails are redirects from a single domain. There's got to be some way to make it work. Any help would be greatly appreciated, Dave Stephan Bosch-2 wrote > + Vacation extension: finally added support for using the original > recipient in vacation address check. It is also possible to disable > the recipient address check entirely. Check doc/vacation.txt for > configuration information.

[Dovecot] Importing emails from PST Archives
by Andre Rodier 27 Mar '13

27 Mar '13

Hello everyone, I am currently migrating a small company from exchange 2003 to Dovecot. So far, the most painful process has been the PST archives. (Except the inconditionals of Outlook) I have been able to create the directory structure using the last version of readpst, with the -r flag. But once this done, I have not been able to find one tool that worked correctly. Maybe the configuration I have is complex. The perl script to transform mbox files into maildirs in the dovecot distribution is old, and crashed many times in the middle of the process. I had a look to the script, and gave up trying to fix it. I found a python script that was supposed to crawl this folder structure, and to replicate it using IMAP commands, but it crashed as well, and restarting the process would import twice the same messages. The script is here: http://costela.net/2011/06/importing-an-outlook-pst-into-imap/ I found another python script that was working better, and seemed to be well written, but with one mbox to one IMAP folder only. It can be found here: http://imap-upload.svn.sourceforge.net/viewvc/imap-upload/trunk/ I have modified, and I have added some minor fixes: - Recursively traverse a folder structure, and replicate it using IMAP commands on the server. - Properly manage folder names with special characters. (dovecot can manage these characters using the listescape plugin). - Avoid taking all the resources of the server (A quirty hack that can change). I am not an expert in Python, and the script has been quickly writter to fit my needs. However I think it can be modified easily to any configuration. In the future, maybe this script can use the libpst python bindings to import the emails directly. The last version of the script, modified is here: https://github.com/arodier/EmailTools/tree/master/Migration. Do not hesitate to help me, to make the script as generic as possible, particularly if you are a python expert. I post this on this list, because I think you maybe interested if you are in the same case as me. The license is not specified, but I will probably use GPLv3. Regards, André

[Dovecot] Released Pigeonhole v0.2.4 for Dovecot v2.0.14
by Stephan Bosch 26 Mar '13

26 Mar '13

Hello Dovecot users, I release a new version of Pigeonhole tonight. This release extends the configuration capabilities of the include and vacation extensions, adds the ihave extension (RFC 5463), and fixes a few small other things. Judging by Timo's plans, this will be one of the last feature releases for Dovecot v2.0, since I'll be switching active development to Dovecot v2.1 once that matures a little more. Changelog v0.2.4: + Vacation extension: finally added support for using the original recipient in vacation address check. It is also possible to disable the recipient address check entirely. Check doc/vacation.txt for configuration information. + Include extension: made limits on the include depth and the total number of included scripts configurable. Check doc/include.txt for configuration information. + Implemented ihave extension. This allows checking for the availability of Sieve language extensions at 'runtime'. Actually, this is checked at compile time. At runtime the interpreter checks whether extensions that were not previously available are still unavailable. If the situation changed, the script is re-compiled and the ihave tests are evaluated again. + Sieve: optimized compilation of tests that yield constant results (i.e. known at compile tme), such as 'true' and 'false'. No code is produced anymore for script sections that are never executed. Also, semantics are not verified anymore in uncompiled script sections. + Made vnd.dovecot.debug extension available to the LDA plugin instead of only the command line tools. + Sieve: redirect action now adds X-Sieve-Redirected-From header (mainly for people using SPF/SRS). - Sieve: fixed bug in handling flags and keywords; in case of error an assertion was triggered. - Script storage: improved handling of unconfigured user home directory. Originally this would produce an unhelpful error message. - Imap4flags extension: prevent forcibly enabling imap4flags when imapflags is enabled. - Fixed various -Wunused-but-set-variable compiler warnings. - Include extension: forgot to check variable identifier syntax for 'global' command. - Sieve: fixed debug mode; no messages were logged in some situations. - sievec tool: forgot to enable -D (debug) parameter. The release is available as follows: http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.4.tar.gz http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.4.tar.gz.sig Refer to http://pigeonhole.dovecot.org and the Dovecot v2.0 wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] Per-user seen flags for public read-only mailboxes
by Guido Berhoerster 26 Mar '13

26 Mar '13

Hi, I have some trouble getting per-user SEEN-flags to work with read-only mailboxes in a public namespace. Basically, I'm following the wiki at http://wiki2.dovecot.org/SharedMailboxes/Public#Maildir:_Per-user_.2BAFw-Se… and the relevant configuration is as follows: namespace { inbox = yes location = prefix = separator = / type = private } namespace { location = maildir:/srv/mail/public:LAYOUT=fs:INDEX=~/public prefix = Public/ separator = / subscriptions = no type = public } plugin { acl = vfile ... } protocol imap { mail_plugins = " acl quota trash zlib autocreate imap_acl imap_quota imap_zlib" } I have a virtual-user setup with static userdb and there is no permissions problem since everything is created through dovecot: mail_gid = vmail mail_location = mdbox:~/mdbox mail_uid = vmail [...] userdb { args = uid=vmail gid=vmail home=/srv/mail/virtual/%n driver = static } The content of /srv/mail/public/dovecot-acl (and the one of all mailboxes below it) is: owner lrwstipekxa authenticated lr Users can access all mailboxes in the Public/ namespace and read the messages and I can see that dovecot.index.cache and dovecot.index.log are created under ~/public, however setting the SEEN flag for a message is ignored since the mailbox is read-only. Changing the ACL from authenticated lr to authenticated lrs allows user to set the SEEN flag, but globally on the actual mailbox. How can I get per-user SEEN flags to work? The Dovecot version is 2.0.9. Thanks, -- Guido Berhoerster

[Dovecot] Dovecot 2.1.15 on CentOS 6.4 with metadata-plugin
by Bruce Marriner 25 Mar '13

25 Mar '13

Hello, I hope somebody can help me with this :) I am trying to get Dovecot 2.1 working with Kolab 3.0 and to start that processes I need? to compile the Dovecot metadata plugin with Dovecot. For the plugin to compile correctly against the Dovecot source code Dovecot must first be patched with a patch from the plugin author (Dennis Schridde) that is currently not part of the Dovecot code (Timo, could this be added to Dovecot?) I am documenting this entire process and once it's finished it may also be helpful to the Dovecot community. You can see some of my progress, or lack of, and errors here : http://bmts.us/wiki/doku.php?id=article:kolab:dovecot In order to compile the plugin I have removed CentOS yum packages for autoconf, automake, and libtool and downloaded, compiled, and installed versions autoconf 2.69, automake 1.12.6, and libtool 2.4.2. If I download Dovecot (not from hg) I can run ./configure and make without any problems. But, to add the patch to Dovecot I need to run the autoreconf command and this is where I have trouble. [root@kolab dovecot-2.1.15]# autoreconf aclocal: warning: autoconf input should be named 'configure.ac', not 'configure.in' configure.in:284: warning: macro 'AM_ICONV' not found in library configure.in:284: error: possibly undefined macro: AM_ICONV If this token and others are legitimate, please use m4_pattern_allow.

[Dovecot] doveadm with multiple commands
by Timo Sirainen 25 Mar '13

25 Mar '13

This has been in my TODO for a while and today I implemented it (but didn't dare to test it yet :) So the problem has been that you want to run for example: doveadm expunge -A mailbox Trash savedbefore 7d doveadm purge -A This is annoying because it scans through the users' mailboxes twice, wasting disk IO and CPU. So how to make it do the scan only once? The syntax I thought of today would be: doveadm multi [-A | -u wildcards] <separator string> <comand 1> [<separator string> <command 2> [...]] So the first two commands could be for example: doveadm multi -A : expunge mailbox Trash savedbefore 7d : purge The ':' character is the separator. Any other string could be used as well, for example "?SEP?" or whatever. Thoughts? Any better name for the command than "multi"?

[Dovecot] Dovecot v2 multiple domains
by Pavel Dimow 25 Mar '13

25 Mar '13

Hello, I would like to have multiple domains on same server (with different ip's) and I want that user logs with username with domain part for every domain, but I can't find any documentation on this. To be more precise I found a post regarding dovecot v1 that suggest making separate init scripts for every domain but it also suggest that dovecot v2 will support this in code. This is the post http://dovecot.org/pipermail/dovecot/2006-April/012455.html Am I missing something or this is not still possible?

[Dovecot] Dovecot DNS queries its own host many times a second
by Dominic Malolepszy 25 Mar '13

25 Mar '13

Hi, We have observed that Dovecot appears to make a DNS lookup of its own hostname many times a second. Each Dovecot server in our cluster appears to be doing around 50 queries per second to find out its own hostname. Rsyslog was the first thing we assumed was the cause, however stopping it did not help. Also the fact that at the time Dovecot was doing around 50 logins a second, seemed to correlate with it making these queries. Is there any reason why Dovecot would need to do a lookup of its own hosts IP address every time? Seems like a strange thing to do and not cache its own hostname. Dominic

[Dovecot] Confirmation Please - Dovecot for Email Delivery
by craig.dovecot＠noboost.org 25 Mar '13

25 Mar '13

Hi All, Spec: Centos 6.3x64 Dovecot-2.0.9-5.el6.x86_64 Goal: 1) Inbound emails are delivered by Dovecot and the UID/GID is determined by a local /etc/dovecot/users file. 2) I'd like to have IMAPS clients authenticate with Dovecot via LDAP. Questions: 1) I've attempted to ensure that Dovecot will always use the local password file for mail delivery as no actual password is needed. Then the LDAP server for when the IMAPS email client connects. This appears to be working as I expect, can anyone confirm/deny the below settings are correct? 2) Is there a Dovecot architecture diagram/documentation anywhere? Settings: ------------------------------------------------------------------------- File: dovecot.conf protocols = imap lmtp listen = * File: 10-auth.conf disable_plaintext_auth = yes auth_username_format = %Ln auth_mechanisms = plain !include auth-passwdfile.conf.ext !include auth-ldap.conf.ext File: auth-passwdfile.conf.ext mail_location = maildir:/home/%n/Maildir #passdb { # driver = passwd-file # args = username_format=%n /etc/dovecot/users #} userdb { driver = passwd-file args = username_format=%n /etc/dovecot/users } File: dovecot-ldap.conf.ext hosts = sysvm-ipa.noboost.org tls = yes tls_ca_cert_dir = /etc/openldap/certs auth_bind = yes auth_bind_userdn = uid=%u,cn=users,cn=accounts,dc=noboost,dc=org base = cn=users,cn=accounts,dc=noboost,dc=org pass_attrs = uid=user pass_filter = (&(objectClass=posixAccount)(uid=%u)) File: /etc/dovecot/users craig:x:890:432:Craig:/home/craig:/bin/bash ------------------------------------------------------------------------- cya Craig

[Dovecot] Reduce logging auth-worker
by Nick Edwards 25 Mar '13

25 Mar '13

Hello Timo We would like to reduce the logging by increasing severity, we don't use syslog since we use log_path = /var/log/dovecot/pop3.log Is there a way auth-worker can be made to log warn|error instead of info? Constantly 1/5th of the log file is filled with auth-work info connecting to mysql socket, which we do not need to see unless, well, we need to see it either via debug, or if there is a problem, I know this can be done from syslog, but we prefer not to use syslog, and the wiki does not indicate it can be done?

[Dovecot] SiS attachment file larger than expected
by Erik Persson 25 Mar '13

25 Mar '13

Hello! Name's Erik and I have been using Dovecot for a few months and I so far quite happy with the software. To this list I am quite new though. After a testing period I have now been running a ~300 user system running CentOS 6 and Dovecot 2.1.14 with Postfix and SiS enabled. For the large part the system is running flawlessly but I have caught a few error messages: imap(censored(a)censored.domain): Error: Attachment file /mail/attachments/70/d0/70d04b12123bfb145983f5a674ee2e65029a4018aff1c6db51993b75f10bf101-117a1a3b06f54251e96200004d877aa0 larger than expected (370113) The total number of files that I have found complaints about in the log are less than 10 accessed by 3 users in a attachment file system that by now is housing 100k + files. The only common denominator I have found so far is that all the attachments are PDF files. Most if not all of the logged files are the only referenced link of the corresponding hash. Any idea what might be causing this and how it can be prevented? I do like to be a bit paranoid when it comes to data integrity. As I am not completely familiar with the dovecot tools I also wonder if there is a way to find the offending message in the mailbox other than trying to access it via a mail client? Best regards and keep up the good work! /Erik

[Dovecot] Reporting on user info
by Alex 24 Mar '13

24 Mar '13

Hi all, I've just installed fc18 with dovecot-2.1.15 and have all the usual services set up and running properly. Of course now management is interested in who is using what service, for how long. Are there any existing reporting features available from within dovecot to provide stats on mail usage over time? Ideally, I'd like to provide a log file and find out who used each service, how long they were logged in, and from where they logged in. It would also be interesting to have a real-time view of who's connected. Does any such utility exist? Thanks, Alex

[Dovecot] Replicator updates
by Timo Sirainen 24 Mar '13

24 Mar '13

Some new features in hg: - replicator now correctly saves/restores state on exit/startup. it won't immediately start resyncing everyone now always. - if sync fails for user, retry in 5 minutes - doveadm replicator status: Give overview of replication status - doveadm replicator status <usermask>: Show users' replication status - doveadm replicator replicate [-p <priority>] <usermask>: Replicate users now. replication_full_sync_interval was also changed to 24h by default. I was thinking that with that and a nightly cronjob running "doveadm replicator replicate '*'" the full syncs could only be done during night times.

Re: [Dovecot] Migrating password scheme
by Joseph Tam 24 Mar '13

24 Mar '13

I tried the userdb prefetch / postlogin script method to do some password manipulation, but it doesn't appear to work for me. In particular, I don't think this method works with userdb { driver = passwd-file args = /path/to/passwd-file userdb_pw=%w } because it doesn't understand arbitrary var=value in the args configuration. Dvoecot seems to accept the entire string as the pathname for a password file. Is there a way to pass the plaintext password to a post-login script using passwd-file userdb? Before this, I managed password manipulation by process tracing dovecot's auth process read() syscalls and parsing out the user/password from the second buffer argument. Quite a hack but it worked.

[Dovecot] Migarting password scheme
by lst_hoe02＠kwsoft.de 24 Mar '13

24 Mar '13

Hello, by the move to Dovecot we try to alter the password encryption stored in the database from MD5 to CRYPT-SHA256 along the Guide at http://wiki2.dovecot.org/HowTo/ConvertPasswordSchemes. It's mostly working but i still have not found out how to pass the cleartext password to the re-encrypting script. According to the HowTo it should be enough to add "'%w' AS userdb_plain_pass" to the passdb query, to get a environment variable $PLAIN_PASS in the post-login script to pass along. This does not work eg. PLAIN_PASS is always empty. This is Dovecot 2.0.19 from Ubuntu 12.04 LTS. Thanks for any help Regards Andreas

[Dovecot] Disallow POP3 from deleting messages
by DormitionSkete＠hotmail.com 23 Mar '13

23 Mar '13

I'd like to use Dovecot as our IMAP server when our users are within our LAN, but I'd also like to give them the ability to access their emails via POP3 when they are outside the LAN. I know most POP3 clients will give their users the option of not deleting the messages from the server after they are downloaded, but is there any way to restrict them from being able to do so at the server level? In other words, I want to disallow the server from accepting the DELE command from POP3 clients. Is that possible? We have some accounts that multiple users need simultaneous access to. I don't want a user to decide to set up a POP3 account on his own on his iPad or something, and inadvertently blow the Inbox away for everybody else. We have a satellite connection, so our upload speeds are real slow. I think POP3 would give a lot better user experience than IMAP when they are outside the LAN. Any help or advice will be greatly appreciated. Peter, hieromonk ---- Dormition Skete Monastery Website: http://www.DormitionSkete.org Convent Website: http://www.HolyApostlesConvent.org ----

Hint http://dovecot.org/list/dovecot/2012-December/069771.html does not seem to be valid for Dovecot 2.2 On the other hand I think it is not a suitable method to include CRLs into CA file. Certificate should include a link to CRL or - better - an URL to OCSP. Does Dovecot support OCSP? best regards Christian

[Dovecot] Altmove doesn't working after a dsync.
by Breno Moreira 22 Mar '13

22 Mar '13

Hi guys, I'm having a problem with the altmove command after a mailbox migration using dsync. What I'm trying to do is move some users from a datacenter to another and, for that, I'm using the dsync feature. First thing I do is run the dsync mirror command, and this is working properly, but all mails are moved to the main path, ignoring the ALT statement in the mail location. So, what I tried to do was run the doveadm altmove to move the old mails to the new alternate storage, but it simply doesn't work or sometimes moves only few messages. After the user receives new messages, these new files are correctly moved. It can be problem with my search parameter in the altmove command? Or this is a normal result? Best Regards, Breno Moreira -- --------------------------------------------------------------------- Breno Moreira

[Dovecot] How do I enable dsync sieve script replication?
by Oli Schacher 22 Mar '13

22 Mar '13

Hi all, Thank you Timo for adding sieve script replication to dsync, much appreciated! Should this run out of the box with 2.2.rc3 and latest pigeonhole+patch or does this have to be enabled in the configuration somehow? I upgraded my dsync replication test setup, but it doesn't sync sieve so far, so I'm not sure if this is a config issue or if I maybe made a mistake while upgrading/patching. btw: not sure if you saw this bugreport, dsync over tcp still produces "no command given" errors randomly (http://www.dovecot.org/list/dovecot/2013-March/088751.html) Thanks Oli #dovecot -n: # 2.2.rc3: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-279.22.1.el6.x86_64 x86_64 CentOS release 6.3 (Final) auth_master_user_separator = * auth_mechanisms = plain login dict { acl = mysql:/etc/dovecot/dovecot-dict-shares.conf quotadict = mysql:/etc/dovecot/dovecot-dict-quota.conf } disable_plaintext_auth = no doveadm_password = <munged> listen = * login_greeting = Dovecot ready. mail_max_userip_connections = 50 mail_plugins = " quota notify replication" 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 namespace { list = children location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u prefix = shared/%%u/ separator = / subscriptions = no type = shared } namespace inbox { inbox = yes location = 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 } prefix = separator = / type = private } passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { acl = vfile:/etc/dovecot/acls acl_shared_dict = proxy::acl mail_replica = tcp:<munged>:1337 quota = dict:::proxy::quotadict quota_rule = *:storage=10M:messages=1000 quota_rule2 = Spam:ignore quota_rule3 = Trash:storage=+100M quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=75%% quota-warning 75 %u sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = pop3 imap lmtp sieve service aggregator { fifo_listener replication-notify-fifo { user = fumail } unix_listener replication-notify { user = fumail } } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { group = fumail mode = 0660 user = fumail } user = root } service dict { unix_listener dict { mode = 0600 user = fumail } } service doveadm { inet_listener { port = 1337 } } service imap { vsz_limit = 2 G } service lmtp { inet_listener lmtp { address = 127.0.0.1 port = 24 } process_min_avail = 5 unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0660 user = postfix } } service managesieve { vsz_limit = 2 G } service pop3 { vsz_limit = 2 G } service quota-warning { executable = script /usr/local/bin/quotawarning.py unix_listener quota-warning { mode = 0666 user = fumail } user = fumail } service replicator { process_min_avail = 1 } ssl_cert = </etc/ssl/<munged>.crt ssl_key = </etc/ssl/<munged>.key userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocol imap { imap_client_workarounds = mail_plugins = " quota notify replication acl imap_acl quota imap_quota" } protocol pop3 { mail_plugins = " quota notify replication quota" pop3_uidl_format = %08Xu%08Xv } protocol sieve { managesieve_logout_format = bytes ( in=%i : out=%o ) } protocol lmtp { deliver_log_format = from=<%f> msgid=%m action=<%$> subject=%s mail_plugins = " quota notify replication sieve quota" postmaster_address = postmaster@<munged> quota_full_tempfail = yes } -- message transmitted on 100% recycled electrons

[Dovecot] v2.2 dsync_brain_lock() FLOCK compatibility issue on Solaris 11.1
by Walter Steiner 22 Mar '13

22 Mar '13

Hello, On Oracle Solaris 11.1 (Solaris gcc-45 package set) core libraries do not provide flock() anymore. in file: src/doveadm/dsync/dsync-brain.c in function: dsync_brain_lock() around line: 234 is a (maybe unintentional) fix reference to FLOCK locks. if (file_wait_lock(brain->lock_fd, brain->lock_path, F_WRLCK, FILE_LOCK_METHOD_FLOCK, brain->lock_timeout, &brain->lock) <= 0) { resulting in a runtime error about unsupported flock() locks. (HAVE_FLOCK is not set by configure script) Personally, I have just changed "FLOCK" to "FCNTL". [ I have tried brain->lock->lock_method but this seems not to be the correct way => compile time error: dereferencing pointer to incomplete type ] Walter

Re: [Dovecot] Problem with Prefetch User Database

I use PAM because of the easyness of blocking specific validated users - you can just add/remove them in a plain text file. Easy administration will be necessary because of the planned huge amount of users on the system (28.000), and sometimes blocking a user is highly time-dependent (e.g. if one answers to a phising mail and sending out his credentials which are then abused for sending spam). I would go over LDAP if there is an equivalent easy way to solve this over LDAP (easy blocking out users by e.g editing a plain text file) - is there any?

[Dovecot] 2.2.rc2: problem with acl_shared_dict
by Lutz Preßler 22 Mar '13

22 Mar '13

Hello, 2.2.rc2, configuration as before: acl_shared_dict=file:... The contents of this file is used for e.g. LISTing shared mailboxes. But even with file and directory beeing world writable, it's not written into on SETACL commands. Instead, at least sometimes (it seems to make a difference if GETACL is used before in the session) the imap process crashes on SETACL or DELETEACL. Feb 26 00:31:52 host dovecot: imap(13373, user) K64y8ZTWOgB/AAAB: Fatal: master: service(imap): child 13373 killed with signal 11 (core dumps disabled) Anything to do for further debugging? Working correctly with 2.1.15. Greetings, Lutz

[Dovecot] director's imap/pop3 login timeout
by Angel L. Mateo 21 Mar '13

21 Mar '13

Hello, We have two (load balanced) director servers in front of 4 dovecot backend servers. Yesterday we had a problem at backend servers for some users (our SSO was down, so IMAP users couldn't authenticate) and this triggered a problem in director servers where almost nobody could open a new session. In our director's logs I could see errors like this: Mar 20 20:52:47 myotis41 dovecot: imap-login: proxy(<user>): Login failed to 155.54.211.162:143: [UNAVAILABLE] Temporary authentication failure. [myotis32:2013-03-20 19:52:47] So, it seems it was trying to authenticate for 1 hour, after that it timed out the login. But this timeout is too long. Is this a director timeout? Or a backend timeout? How can I reduce it? -- Angel L.
