[Dovecot] NTLM authentication with Outlook 2010
by Kevin Bridges 01 May '13

01 May '13

All, I have a Ubuntu 12.04.2 box running Dovecot 2.0.19. I have it configured for our active directory. WBinfo and ntlm_auth work great. I am trying to get sso to work with ntlm. Gssapi with thunderbird works like it should. I just cant get ntlm with outlook 2010 to work for sso. I get prompted for my password each time I open outlook. I have attached my config for dovecot. Any help would be much appreciated. # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-39-virtual x86_64 Ubuntu 12.04.2 LTS auth_debug = yes auth_debug_passwords = yes auth_mechanisms = gssapi ntlm auth_use_winbind = yes auth_verbose = yes auth_verbose_passwords = plain debug_log_path = /var/log/dovecot_debug.log log_path = /var/log/dovecot.log mail_location = mdbox:~/mdbox passdb { driver = pam } plugin { quota_rule = *:storage=2G quota_warning = storage=95%% quota-warning 95 %u } protocols = " imap" service auth-worker { user = root } service auth { user = root } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } protocol imap { mail_plugins = " quota imap_quota" }

[Dovecot] Antispam r49 breaks Dovecot v2.1
by Steffen Kaiser 30 Apr '13

30 Apr '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear Eugene, patch 49 breaks compilation with Dovecot v2.1. Attached patch encloses the change in a #if. To feed the #if the actual Dovecot version, I've introduced an extra variable in extra.mk, but I cannot help with making the GNU configure stuff doing it right away. There will be numerous other ways to get the Dovecot version into the source ... . Maybe, Timo would add a binary version of the Dovecot version in its config.h ? In order to be able to built version-aware plugins.

[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.

[Dovecot] Dovecot Solr Panic
by Andre Rodier 29 Apr '13

29 Apr '13

Hello Everyone, I have a small base of users (30), but a lot of emails. I have an error again when I am indexing a virtual folder with a large number of folders. 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

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?

Hello, there seems to be a typo in the dovecot-2.2.1-sources: in dovecot-2.2.1/src/lib-http/Makefile.in at line 758 the two lines ../lib-test/libtest.la \ ../lib/liblib.la do not fit into the Makefile-syntax. At compile-time they produce the error make: Fatal error in reader: Makefile, line 725: Unexpected end of line seen If I remove these two lines, everything compiles fine. Could you please check this. Thanks, Andreas -- ________________________________________________________________________ Dr. Andreas Piper, Hochschulrechenzentrum der Philipps-Univ.

[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

[Dovecot] Sieve - BCC
by iliusha 21 Apr '13

21 Apr '13

Hi ! 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

The thing is if a user A updates, deletes, flags mail messages in the imap folders the changes don't get propagated to the other mail clients. To state this clearly, PC (A) thunderbird has an account SALES, Maildir etc PC (B) thunderbird also has the SALES account. Changes from PC (A) and vice-versa like marks,deletes, or moves mails around will randomly get propagated to PC (B) Sometimes they do sometimes they don't.

[Dovecot] Dovecot and port forwarding
by Slawomir Wawak 19 Apr '13

19 Apr '13

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.

Changes from PC (A) and vice-versa like marks,deletes, or moves mails around will randomly get propagated to PC (B) Sometimes they do sometimes they don't. This never occured with previous version 1.2.xx I am attaching my doveconf -a output .. Please Help, Thanks in advance Harry

[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] auth: passwd file (info): unknown user
by Jim Knuth 18 Apr '13

18 Apr '13

Hello, the problem is: The users are system users (by Confixx) say webxpy. But behind it e-mail puts of course address like info(a)domain.de and so on. Everything functions perfectly, nevertheless, is following in the log. … … dovecot: auth: passwd file (jk): unknown user … dovecot: auth: passwd file (jim.knuth): unknown user … dovecot: auth: passwd file (info): unknown user … and so on It is tried obviously, before the domain part in the passwd file to find user info … However, there is in it only webxpy. How can I solve this dilemma, by which does this come then? auth_username_format = %n Thanks in advance as attached mine dovecot-n -- Mit freundlichen Grüßen, with kind regards, Jim Knuth

[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

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.

[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] [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().

[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. Here's a log entry that demonstrates this: Apr 15 01:20:01 mail postfix/smtpd[4284]: connect from localhost[127.0.0.1] Apr 15 01:20:01 mail postfix/smtpd[4284]: lost connection after CONNECT from localhost[127.0.0.1] Apr 15 01:20:01 mail postfix/smtpd[4284]: disconnect from localhost[127.0.0.1] Apr 15 01:20:01 mail dovecot: pop3-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=127.0.0.1, lip=127.0.0.1, secured, session=<FGhS62HaIwB/AAAB> So I thought it was a problem with SASL not liking PLAIN authentication. When I go to /etc/dovecot and print the contents of dovecot.conf, I see that auth_mechanisms = plain login. root@mail:/etc/dovecot# more dovecot.conf listen = *,[::] protocols = imap pop3 auth_mechanisms = plain login disable_plaintext_auth = no log_timestamp = "%Y-%m-%d %H:%M:%S " mail_privileged_group = vmail ssl_cert = </etc/postfix/smtpd.cert ssl_key = </etc/postfix/smtpd.key passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { quota = dict:user::file:/var/vmail/%d/%n/.quotausage sieve=/var/vmail/%d/%n/.sieve } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = vmail mode = 0600 user = vmail } user = root } protocol imap { mail_plugins = quota imap_quota } protocol pop3 { pop3_uidl_format = %08Xu%08Xv mail_plugins = quota } protocol lda { mail_plugins = sieve quota } At this point I'm not sure what to think about this. 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
by Luigi Rosa 16 Apr '13

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. I exported the old (now in production) /var/spool/mail with (ro,no_root_squash) parameters I mounted the NFS on the new server with -o nolock This is not the first time I use this method and it always worked. Until now. If I try to rsync the current maildir structure to the new server I get MANY errors like: rsync: readdir("/mnt/xxxx/username"): Invalid argument (22) rsync: readdir("/mnt/xxxx/username/.Deleted Messages/cur"): Too many levels of symbolic links (40) I tried with rsync -a rsync --force --delete-after --devices --specials --sparse -tPrlHpogEAX rsync --force --delete-after --devices --specials --sparse -tPrlHpogEAXL but the result is the same.

[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.

By contrast, 2.1.16 compiled (and runs) just fine. I'm surprised that this hasn't cropped up elsewhere.

[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
by Matthias Hofer 13 Apr '13

13 Apr '13

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

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?)

[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

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

Re: [Dovecot] Any simple way to block logins by IP address?

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>
