Virtual User Authentication
by Jerry 11 Nov '14

11 Nov '14

I have only "virtual users" on the system that I maintain. I am using Postfix which is configured to use Devecot for authentication. I get several attempts everyday to hack into the system, both via Postfix and directly via Dovecot. The following is from the dovecot log: Nov 11 04:14:48 auth-worker(21005): Error: pam(monica,69.193.88.146): pam_authenticate() failed: authentication error (/etc/pam.d/dovecot missing?) Now, I do not use "pam" on this system. Is there a way I can eliminate Dovecot from trying to use it? -- Jerry

Replication Advice Needed
by Asai 11 Nov '14

11 Nov '14

I successfully set up Dovecot replication, having 2 servers syncing with each other. While I had both servers in the same room on a Gigabit network, they were syncing fine. But I took one to another location, and syncing was turned off for about 2 weeks. Now I've turned both back on, they're sort of syncing, but not really. The one remote server is not populating emails into various folders and it really should be cranking to sync those emails. Do anyone have any insights on how we could troubleshoot this? -- --Asai

deliver an email to a large number of local users directly via doveadm
by Mahdi Mahdi 11 Nov '14

11 Nov '14

Hello,We have a mail service that uses postfix and dovecot. We would like to send an email to a large number of users(about 100K). However, it takes too long to send the email through smtp. Is there any solution to deliver the email locally to all user mailboxes directly.dovecot uses lmtp for transfering local emails. the worst solutoin is that copy the email to all mailboxes via linux file system. But we would prefer to use some tools provided by dovecot like doveadm. is there any way to do this job?

mail location change results in various errors

I have a sendmail/dovecot imap/pop3 system that has been running with the following mail_location: mail_location = mbox:/var/empty:INBOX=/var/spool/mail/%u:INDEX=/var/indexes/%u In order to reduce errors and simplify operation I removed imap and am now only responding to pop3.

Performance issue
by absolutely_free＠libero.it 10 Nov '14

10 Nov '14

Hi, Since few days I noticed very high load on my mailserver (Centos 6.6 64bit, 8 GB RAM, 2 x CPU 3.00GHz I am using Dovecot + Postfix + Roundcube + Nginx. I have about 10000 users. Spool is on network attached storage (Coraid). File system is ext4 (mounted with noatime). Problem appears almost every morning (while load is normal during afternoon). I suspect that this can be related to some user that have so many messages in his mailbox. How can I troubleshoot this? Here some messages that I got in maillog: Warning: Maildir: Scanning /var/spool/pop/domains/xxxx.it/YYYYYYYYY/Maildir/new took 71 seconds (1 readdir()s, 1 rename()s to cur/) Warning: Maildir /var/spool/pop/domains/zzzz/WWWWWWWWWWWW/Maildir/.Trash: Synchronization took 74 seconds (5 new msgs, 0 flag change attempts, 0 expunge attempts) dovecot: imap(xxxx(a)zzzz.it): Warning: Inotify instance limit for user 89 (UID postfix) exceeded, disabling. Increase /proc/sys/fs/inotify/max_user_instances tail: inotify cannot be used, reverting to polling: Too many open files My relevant dovecot conf: mail_location = maildir:/coraid-s2l2/domains namespace { type = private separator = . prefix = INBOX. inbox = yes } mail_uid = 89 mail_gid = 89 mail_fsync = never first_valid_uid = 89 first_valid_gid = 89 maildir_very_dirty_syncs = yes mbox_write_locks = fcntl thank you very much!

Best practise for deleting with Thunderbird
by Stefan G. Weichinger 09 Nov '14

09 Nov '14

As I mentioned in another thread I set up these 2 namespaces for a couple of users: namespace { inbox = yes location = prefix = separator = / type = private } namespace { location = maildir:/home/vmail/oeffentlich:INDEXPVT=/home/vmail/public/index/%d/%u/index prefix = Oeffentlich/ separator = / subscriptions = yes type = public } It is planned that they all will use Thunderbird (on MS Windows) to access their mailboxes. Now when I create a folder in the public space and try to delete it via thunderbird I get something like: "Renaming not supported across non-private namespaces" As far as I found out by browsing the web this is related to Thunderbird trying to move (=rename) the mail from the public to the private namespace, correct? Setting TB to immediately remove mails (tested that, this works) seems a bit scary to me: this removes a safety layer for the users because this would also apply to their personal maildirs. Is there any more elegant way of solving this? Do I have to set up some kind of ACLs? Some kind of "public paperbin folder" ?? Pls help me to understand this better ;-) Regards, Stefan

Improvement proposal
by Jorge Bastos 09 Nov '14

09 Nov '14

Hi, I'd like to purpose a small improvement. When a user has a quota set in message limit instead of bytes, the returning message it's the same as in bytes limit quota (Quota exceeded (mailbox for user is full)) If possible, when the user has the message limit, it could return something different like: Quota exceeded (max messages reached for user) Thanks, Jorge,

Dovecot quota via custom column

Hello, we have multiple domains connected to single user account and we want to have quota counted via this column - called account_id. Users are stored in mysql database. --------------------------------------------------------------------------------- iterate_query = SELECT email AS user FROM mailboxes user_query=SELECT email, 501 AS uid, 501 AS gid, CONCAT('*:storage=',quota,'M') AS quota_rule FROM mailboxes AS m WHERE email='%u' password_query=SELECT email AS user, pw_hash AS password, CONCAT('*:storage=',quota,'M') AS userdb_quota_rule FROM mailboxes AS e WHERE email='%u' --------------------------------------------------------------------------------- We have quota stored in dovecot dictionary and as usable variables we found only - http://wiki2.dovecot.org/Variables. Is there any way to do use account_id as quota username? Thanks, Filip Bartmann

Virtual alias with dovecot

I'd like to also simplify the mail_location to get rid of index errors since I don't need indexes: mail_location = mbox:/var/spool/mail:INBOX=/var/spool/mail/%n But when I applied the new mail_location I began to get the following five errors: Nov 6 23:17:24 sendmail dovecot: pop3(chayes): Warning: UIDVALIDITY changed (1132434125 -> 1205169149) in mbox file /var/spool/mail/chayes Nov 6 23:17:26 sendmail dovecot: pop3(chayes): Panic: Message unexpectedly expunged from index Nov 6 23:17:26 sendmail dovecot: pop3(chayes): Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0() [0x3340045e2a] -> /usr/lib64/dovecot/libdovecot.so.0() [0x3340045e6e] -> /usr/lib64/dovecot/libdovecot.so.0(i_fatal+0) [0x3340019eb3] -> /usr/lib64/dovecot/libdovecot-storage.so.0() [0x3ef62567ed] -> /usr/lib64/dovecot/libdovecot-storage.so.0() [0x3ef6256e75] -> /usr/lib64/dovecot/libdovecot-storage.so.0() [0x3ef62928ed] -> /usr/lib64/dovecot/libdovecot-storage.so.0(index_mail_set_seq+0x76) [0x3ef6294ae6] -> /usr/lib64/dovecot/libdovecot-storage.so.0() [0x3ef625698c] -> dovecot/pop3() [0x405ec7] -> dovecot/pop3(client_command_execute+0x6d7) [0x4071c7] -> dovecot/pop3(client_handle_input+0x78) [0x405618] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_call_io+0x36) [0x3340052c36] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run+0xa7) [0x3340053a57] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_run+0x28) [0x3340052778] -> /usr/lib64/dovecot/libdovecot.so.0(master_service_run+0x13) [0x334003e3c3] -> dovecot/pop3(main+0x283) [0x403cc3] -> /lib64/libc.so.6(__libc_start_main+0xf5) [0x359f821a05] -> dovecot/pop3() [0x403e2d] Nov 6 23:17:26 sendmail dovecot: pop3(chayes): Fatal: master: service(pop3): child 3358 killed with signal 6 (core dumps disabled) Nov 6 23:18:00 sendmail dovecot: pop3(jbkirk): Error: open(/var/spool/mail/.imap/INBOX/dovecot.index.log) failed: Permission denied (euid=2151(jbkirk) egid=12(mail) missing +r perm: /var/spool/mail/.imap/INBOX/dovecot.index.log, dir owned by 3575:12 mode=0770) dovecot -n output # 2.1.16: /etc/dovecot/dovecot.conf # OS: Linux 3.9.2-200.fc18.x86_64 x86_64 Fedora release 18 (Spherical Cow) ext4 auth_mechanisms = plain login auth_verbose = yes auth_verbose_passwords = plain disable_plaintext_auth = no mail_location = mbox:/var/empty:INBOX=/var/spool/mail/%u:INDEX=/var/indexes/%u 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 } protocols = pop3 ssl = no ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } What do I need to do to transition to the new mail_location without the errors?

Dovecot replication causing deleted emails to reappear
by Asai 06 Nov '14

06 Nov '14

Greetings, I've set up replication successfully on two Dovecot servers. I had fully synced the servers but then took one offline for 2 weeks. When I restored it, the servers synced but ended up replacing deleted emails in random people's inboxes. I'm using maildir. Does anyone have any insights as to correcting this issue? Asai -- --Asai

Dovecot-lda permission errors or maybe authentication errors?
by Robert Kryger 06 Nov '14

06 Nov '14

I am a new dovecot user who recently transitioned my old mailserver to a new CentOS/Postfix/Dovecot system. I am running a simple configuration with about a dozen system users and Maildir folders. The e-mail setup seems to be running fine when I use the default local-delivery-agent in Postfix. However, I am trying to use the dovecot-lda instead so I can take advantage of the sieve functionality. I have tried to specify the dovecot-lda in two ways. First, in the /etc/postfix/main.cf file: mailbox_command = /usr/libexec/dovecot/dovecot-lda -f "$SENDER" -a "$RECIPIENT" or alternatively, I leave the mailbox_command blank and specify the following in the .forward file of a test user: | "/usr/libexec/dovecot/dovecot-lda" Either approach gives me the same error(s). When a mail message is sent to the test user USER1, the following errors appear in the dovecot-lda error file: Nov 04 08:47:29 lda(user1): Error: chdir(/home/user1/) failed: Permission denied (euid=524(user1) egid=524(user1) stat() failed: No such file or directory, euid is not dir owner) Nov 04 08:47:29 lda(user1): Error: chdir(/home/user1) failed: Permission denied Nov 04 08:47:29 lda(user1): Error: user user1: Initialization failed: Namespace 'INBOX.': stat(/home/user1/Maildir) failed: Permission denied (euid=524(user1) egid=524(user1) stat() failed: No such file or directory, euid is not dir owner) Nov 04 08:47:29 lda(user1): Fatal: Invalid user settings. Refer to server log for more information. Nov 04 08:47:29 lda(user1): Error: chdir(/home/user1/) failed: Permission denied (euid=524(user1) egid=524(user1) stat() failed: No such file or directory, euid is not dir owner) Nov 04 08:47:29 lda(user1): Error: chdir(/home/user1) failed: Permission denied Nov 04 08:47:29 lda(user1): Error: user user1: Initialization failed: Namespace 'INBOX.': stat(/home/user1/Maildir) failed: Permission denied (euid=524(user1) egid=524(user1) stat() failed: No such file or directory, euid is not dir owner) Nov 04 08:47:29 lda(user1): Fatal: Invalid user settings. Refer to server log for more information. At first, I interpreted this to mean the file permissions were not set correctly on the home directory or the Maildir folder. However, I have opened these up to full rwx access for everyone and I still get the same errors. Alternatively, perhaps this is related somehow to the dovecot-lda authentication process via the password or user databases, but I can't make any sense of the documentation. Can anyone suggest what might be wrong or how to better diagnose? For reference, I am running dovecot version 2.0.9. The dovecot-lda process also outputs the following messages (not errors) when a test message is sent to the USER1 account: Nov 04 08:47:29 lda: Debug: Loading modules from directory: /usr/lib64/dovecot Nov 04 08:47:29 lda: Debug: Module loaded: /usr/lib64/dovecot/lib90_sieve_plugin.so Nov 04 08:47:29 lda(user1): Debug: Effective uid=524, gid=524, home=/home/user1 Nov 04 08:47:29 lda(user1): Debug: Namespace : type=private, prefix=INBOX., sep=., inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:~/Maildir Nov 04 08:47:29 lda(user1): Debug: maildir++: root=/home/user1/Maildir, index=, control=, inbox=/home/user1/Maildir Nov 04 08:47:29 lda: Debug: Loading modules from directory: /usr/lib64/dovecot Nov 04 08:47:29 lda: Debug: Module loaded: /usr/lib64/dovecot/lib90_sieve_plugin.so Nov 04 08:47:29 lda(user1): Debug: Effective uid=524, gid=524, home=/home/user1 Nov 04 08:47:29 lda(user1): Debug: Namespace : type=private, prefix=INBOX., sep=., inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:~/Maildir Nov 04 08:47:29 lda(user1): Debug: maildir++: root=/home/user1/Maildir, index=, control=, inbox=/home/user1/Maildir The output of dovecot -n is: # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-431.29.2.el6.x86_64 x86_64 CentOS release 6.5 (Final) auth_debug = yes auth_debug_passwords = yes auth_mechanisms = plain login disable_plaintext_auth = no login_trusted_networks = 71.xx.xx.xx 71.xx.xx.xy 71.xx.xx.xz 71.xx.xx.yx mail_debug = yes mail_location = maildir:~/Maildir 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 mbox_write_locks = fcntl namespace { inbox = yes location = prefix = INBOX. separator = . } passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_global_dir = home/sieve sieve_max_script_size = 1M } protocols = imap lmtp sieve service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } service managesieve-login { inet_listener sieve { port = 4190 } } ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } protocol lda { info_log_path = /var/log/dovecot-lda.log log_path = /var/log/dovecot-lda-errors.log mail_plugins = sieve postmaster_address = postmaster(a)xxxxxxx.com }

Even better it would be to have a recipe for a custom SELinux policy to not be mislead switching off SELinux at all. Such a custom policy is necessary when storing mail in the user's homedir because files created there get a wrong SELinux context for that usecase by default. An general overview about this topic can be found on http://wiki.centos.org/HowTos/SELinux Kind regards Alexander

Can I take mail from Maildir mailbox and deliver it as new?
by James Pryor 06 Nov '14

06 Nov '14

Hello list, I have a need for someone to point me in the right direction. Our old email system (system A) had an account that acted as a mailing list accumulator/archiver. This account was a member of every list and mail would be sent to it's address. The strange part is that email was not delivered to system A because there was a . (dot) forward alias to another machine (system B) that runs sendmail. System B's sendmail then slurped up the incoming mail and processed it in some fashion which I do not care about. On our new mail server (system C (OS is RHEL6.5, dovecot-2.0.9-7.el6_5.1.x86_64, postfix-2.6.6-6.el6_5.x86_64)), I performed a bulk Linux account and mailbox migration from system A to system C using postfix/dovecot/imapsync. But I forgot to put the alias in place on system C to send all incoming that special account's mail on system B. So mail started to get delivered to local user ar_list on system C. So now I have a Maildir format mailbox on system C that has mail in it and I want to be able to manipulate and/or re-send those emails as new mail to system B. Once it is received by sendmail on system B, then I don't care about it any more. Is there a way to take mail sitting on disk in a mailbox and deliver it as if it was new mail to some other machine? Thanks, James -bash-4.1$ ls -l total 566 drwx------ 2 ar_list users 2048 Aug 7 21:29 cur -rw------- 1 ar_list users 12556 Oct 8 17:09 dovecot.index -rw------- 1 ar_list users 378880 Oct 9 14:41 dovecot.index.cache -rw------- 1 ar_list users 2580 Oct 9 14:41 dovecot.index.log -rw------- 1 ar_list users 65549 Oct 9 14:41 dovecot-uidlist -rw------- 1 ar_list users 8 Aug 7 19:38 dovecot-uidvalidity -r--r--r-- 1 ar_list users 0 Aug 7 19:38 dovecot-uidvalidity.53e40ddc drwx------ 2 ar_list users 100352 Oct 9 14:41 new drwx------ 2 ar_list users 2048 Oct 9 14:41 tmp -bash-4.1$ ls new/ | wc -l 1020 -bash-4.1$ ls cur | wc -l 25

Alexander, You are absolutely right - I apologize for my confusion regarding SElinux. In fact, when I turn off SElinux in /etc/selinux/config (setting SELINUX=disabled, instead of =enforcing) then dovecot-lda starts working. Thanks for the advice - I have been fighting with this for several weeks without making headway! Robert

gssapi considered as PLAIN?
by Harry Schmalzbauer 05 Nov '14

05 Nov '14

Hello, as soon as I set "disable_plaintext_auth = yes", AUTH=GSSAPI vanishes from capabilities. ([CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS AUTH=GSSAPI AUTH=PLAIN AUTH=LOGIN] vs [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS LOGINDISABLED]) Why? I'm wondering especially because at http://wiki2.dovecot.org/Authentication/Mechanisms, GSSAPI is correctly listed under “Non-plaintext authentication“. Thanks, -Harry

ntlm_auth seems ok, initial auth failure with dovecot2 (and winbind 4.1.13)
by Harry Schmalzbauer 05 Nov '14

05 Nov '14

Hello, I've read quite often that there are problems with ntlm_auth helper (last one here http://www.dovecot.org/list/dovecot/2014-June/096561.html) But haven't found any confirmation, neither it's working for anybody else nor that it's known taht this issue needs debuging. Like for ohers, my authentication tests from the commandline with ntlm_auth exactly give expected results. But initial authentication (with Outlook) fail at first, but after entering the user's password, nevertheless succeeds with mech=NTLM. See the attached ntlm-log.txt Can't exactly tell when this regression occured, one year ago nobody had to enter his password, it worked like intended with Outlook (which still is version 2010). Any idea how to debug? It could be also a regression in samba, both highly appreciated applications were upgraded at the same time… Thanks, -Harry

calling post-login script with doveadm

Hello everyone, I'm trying to execute some commands with doveadm but I need some information loaded in a post-login script before running these commands. Is possible to run the post-login script while executing doveadm? I've found how to do something similar with -o key=value to override settings, but I want to change a namespace location, as done in the post-login script: ... export USERDB_KEYS="$USERDB_KEYS namespace/archivo/location" exec env "NAMESPACE/ARCHIVO/LOCATION=$location" "$@" ...

Public mailbox confusion
by Stefan G. Weichinger 05 Nov '14

05 Nov '14

greets, I am quite sure I ask some faq here ... sorry, but I am confused by the many options and choices here. What I want to do is: I migrate lots of public folders from a MS Exchange Server ... The customer wants that there is a "Public" folder containing all these hundreds of folders, the public folder should be visible for all the dovecot-users and all the subfolders should be automatically subscribed as soon a new user logs in. What I have now: namespace { type = private separator = / prefix = inbox = yes } namespace { type = public separator = / prefix = Public/ location = maildir:/home/vmail/public:INDEXPVT=/home/vmail/public/index/%d/%u/index subscriptions = yes } As far as I see from testing this doesn't yet work that way. When I open the mailbox with eg. roundcube I see "Public" but nothing below it ... Could someone please give me a good pointer here? Thanks! Stefan

sieve replication and .dovecot.lda-dupes
by Jan Behrend 05 Nov '14

05 Nov '14

Hello list, I have a replicated dovecot with two servers. People seem to get vacation responses more often then it is specified in "days: XX", depending on which dovecot instance they receive the incoming mail. Is ".dovecot.lda-dupes" replicated? The other problem is that the vacation response is coming from the wrong address depending on which field the recipient was listed: "to:" or "cc:" Here is my test example: g9-rz has the vacation rule set up: date | mail -s test -r jbehrend(a)mpifr-bonn.mpg.de -c g9-rz(a)mpifr-bonn.mpg.de jan(a)flatpick.de and this returns this vacation response: ### snip ### Return-Path: <> Delivered-To: <jbehrend(a)mpifr-bonn.mpg.de> Received: from mail2.mpifr-bonn.mpg.de ([134.104.18.60]) by mailbox2.mpifr-bonn.mpg.de (Dovecot) with LMTP id +pgPDzm1WFSn9wAAvl5QjA for <jbehrend(a)mpifr-bonn.mpg.de>; Tue, 04 Nov 2014 12:16:13 +0100 X-Sieve: Pigeonhole Sieve 0.4.2 Message-ID: <dovecot-sieve-1415099773-541512-0(a)mailbox1.mpifr-bonn.mpg.de> Date: Tue, 04 Nov 2014 12:16:13 +0100 From: jan(a)flatpick.de To: <jbehrend(a)mpifr-bonn.mpg.de> Subject: Vacation In-Reply-To: <E1Xlc5t-0001LT-Bu(a)jb1.mpifr-bonn.mpg.de> References: <E1Xlc5t-0001LT-Bu(a)jb1.mpifr-bonn.mpg.de> Auto-Submitted: auto-replied (vacation) Precedence: bulk MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 8bit X-Evolution-Source: 1385020682.6450.3@jb1 Ain't here!

However, when I tried to index my inbox with "doveadm index -A '*'" I get: doveadm(infoomatic): Error: fts_tika: PUT http://localhost:8081/tika failed: 500 Server Error doveadm(infoomatic): Warning: I/O leak: 0x7f4f697bb170 (line 127, fd 24) doveadm(infoomatic): Panic: file ioloop-iolist.c: line 22: unreached doveadm(infoomatic): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x67f30) [0x7f4f697e8f30] -> /usr/lib/dovecot/libdovecot.so.0(default_fatal_handler+0x2a) [0x7f4f697e8f9a] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7f4f6979c515] -> /usr/lib/dovecot/libdovecot.so.0(+0x79b0d) [0x7f4f697fab0d] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handle_add+0x3b) [0x7f4f697fb2ab] -> /usr/lib/dovecot/libdovecot.so.0(+0x78cf1) [0x7f4f697f9cf1] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_move_io+0x3e) [0x7f4f697fa93e] -> /usr/lib/dovecot/libdovecot.so.0(connection_switch_ioloop+0x14) [0x7f4f697e6df4] -> /usr/lib/dovecot/libdovecot.so.0(http_client_switch_ioloop+0x28) [0x7f4f697bf8e8] -> /usr/lib/dovecot/libdovecot.so.0(+0x36a86) [0x7f4f697b7a86] -> /usr/lib/dovecot/modules/lib21_fts_solr_plugin.so(solr_connection_post_more+0x29) [0x7f4f68d9f069] -> /usr/lib/dovecot/modules/lib21_fts_solr_plugin.so(+0x3547) [0x7f4f68d9b547] -> /usr/lib/dovecot/modules/lib20_fts_plugin.so(fts_build_mail+0x35c) [0x7f4f68faaffc] -> /usr/lib/dovecot/modules/lib20_fts_plugin.so(+0xd3ee) [0x7f4f68fb03ee] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_precache+0x19) [0x7f4f69ac3c39] -> doveadm() [0x419501] -> doveadm() [0x4153c3] -> doveadm(doveadm_mail_try_run+0x48c) [0x4162ac] -> doveadm(main+0x3d8) [0x412588] -> /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xf5) [0x7f4f693dcec5] -> doveadm() [0x4127a4] Aborted (core dumped) The last messages of the tika-server: Nov 04, 2014 10:18:17 PM org.apache.tika.server.TikaResource logRequest INFO: tika (video/x-ms-wmv) Nov 04, 2014 10:18:17 PM org.apache.tika.server.TikaResource$3 write WARNING: tika: Text extraction failed org.apache.tika.exception.TikaException: Unexpected RuntimeException from org.apache.tika.server.TikaResource$1@44742f73 Nov 04, 2014 10:18:17 PM org.apache.cxf.jaxrs.utils.JAXRSUtils logMessageHandlerProblem SEVERE: Problem with writing the data, class org.apache.tika.server.TikaResource$3, ContentType: text/plain Nov 04, 2014 10:18:17 PM org.apache.cxf.jaxrs.impl.WebApplicationExceptionMapper toResponse WARNING: javax.ws.rs.WebApplicationException: HTTP 415 Unsupported Media Type dovecot -n: # 2.2.15: /etc/dovecot/dovecot.conf # OS: Linux 3.13.0-39-generic x86_64 Ubuntu 14.04.1 LTS ext4 auth_username_format = %n disable_plaintext_auth = no mail_gid = vmail mail_home = /var/lib/vmail/home/%u mail_location = mdbox:/var/lib/vmail/mail/%u mail_plugins = fts fts_solr mail_uid = vmail 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 ihave duplicate imapflags mdbox_rotate_size = 32 M 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-ldap.conf.ext driver = ldap } plugin { fts = solr fts_autoindex = yes fts_solr = url=http://localhost:8080/solr/ break-imap-search fts_tika = http://localhost:8081/tika sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_extensions = +imapflags } protocols = " imap sieve" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = vmail user = vmail } } service managesieve-login { inet_listener sieve_deprecated { port = 2000 } } ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol lda { mail_plugins = fts fts_solr sieve } Has anyone hints?

With as much information as you already have in your database schema you may want to look at using the Prefetch userdb. http://wiki2.dovecot.org/UserDatabase/Prefetch P.S.

SSL Client authentication with trustcenter-certificate
by dovecot.pkoch＠dfgh.net 04 Nov '14

04 Nov '14

Dear reader, we are using dovecot 2.2.7 and like it very much. Authentication is done via a checkpassword program that does two things: 1) check wether the client has connected via SSL using a client certificate 2) check wether the client is using a one time password generator Most of our users are using certificates that we have created ourself. These certificates contain a x500uniqueidentifier. But some users are using certificates from a german trust center and these certificates do not contain a x500uniqueIdentifier nor something similar. I would like to map these certificates to user accounts and my first idea was to do so from my checkpassword programm. But how do I find out the client-certificate from within a checkpassword script. I tried to add an additional entry to auth_request_var_expand_static_tab and fill in that environment variable in auth_request_get_var_expand_table_full() (both in src/auth/auth-request.c). But where do I find the SSL-context from which I can extract the client certificate? Kind regards Peter Koch

Released Pigeonhole v0.4.5 for Dovecot v2.2.15.
by Stephan Bosch 02 Nov '14

02 Nov '14

Hello Dovecot users, Unfortunately, Pigeonhole v0.4.4 had a rather big issue with error handling and the execution of the implicit keep. This problem presented itself for example when users exceeded their quota. This did not result in the proper rejection message. This is why I quickly release a new version. Changelog v0.4.5: + Added a Pigeonhole version banner to doveconf output. This way, future bug reports will also include Pigeonhole version information. - Fixed handling of implicit keep. Last version erroneously reported that implicit keep succeeded after an earlier failure, while it in fact had failed. Particularly occurred for mailbox quota errors. - Fixed segfault occurring on SunOS systems when there is no active script. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.5.tar… http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.5.tar… 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

Sa-learn-pipe.sh script modification
by Pierre Barre 01 Nov '14

01 Nov '14

Hello, I've seen on this wiki page: http://wiki2.dovecot.org/Plugins/Antispam A script called "sa-learn-pipe.sh". I've tested it but it slow things down because dovecot wait for the script termination. So, I've made a modification. Now, the task is running in the background and dovecot move the mail without waiting for the script termination: #!/bin/bash echo /usr/bin/sa-learn $* /tmp/sendmail-msg-$$.txt echo "$$-start ($*)" >> /tmp/sa-learn-pipe.log #echo $* > /tmp/sendmail-parms.txt cat<&0 >> /tmp/sendmail-msg-$$.txt /usr/bin/sa-learn $* /tmp/sendmail-msg-$$.txt && rm -f /tmp/sendmail-msg-$$.txt & echo "$$-end" >> /tmp/sa-learn-pipe.log exit 0 I want know if this can cause any problem ? Thanks. -- Best regards, Pierre Barre.

SSLv3 attack on pop3?
by Hans Morten Kind 31 Oct '14

31 Oct '14

We turned off SSLv3 support on our pop/imap running dovecot on Oct 16th, we did check that all users where using TLSv1 and there have been no complaints (except one old windows-phone). But at 13:00 UTC today, suddenly strange entries is seen in the logfile: Error: SSL: Stacked error: error:140943F2:SSL routines:SSL3_READ_BYTES:sslv3 alert unexpected message: SSL alert number 10 Followed by: pop3-login: Disconnected (no auth attempts in 2 secs) user=<>, rip= Some 20 ips have been seen so far, all ips are uniq and none have used our server lately. Just one resoved and it's name ends .cn, some lookups with whois leads to the same origin for all. This makes me anxious that some have made some poodle-like thing for pop3? hmk

vpopmail, open_smtp_relay and non-PLAIN auth mechs
by Jim Jagielski 31 Oct '14

31 Oct '14

I've noticed that if using the vpopmail auth setup, that the roaming-user functionality provided via open_smtp_relay() is only done if the auth mechanism is PLAIN. For example, if the client authenticates via DIGEST-MD5, the open relay file is not updated, as it should be. This is due to the call to open_smtp_relay only being done via vpopmail_verify_plain(). Instead, imo, that call should be done in auth_request_success() in the auth-request.c file, so that it is done however the authentication is done, as long as it is successful. Attached is a patch for 2.2.15. Let me know if attachments are not the preferred method and I'll cut/paste. tia! -- Jim Jagielski

Question wrt. dovecot replicator
by Remko Lodder 30 Oct '14

30 Oct '14

Hi People, I recently setup a replication service within dovecot between two machines in different datacenters, which has the following configuration; (yes it is hashed out, because I needed to) #service replicator { # unix_listener replicator-doveadm { # mode = 0666 # } # process_min_avail = 1 #} # #service aggregator { # fifo_listener replication-notify-fifo { # mode = 0666 # #user = vmail # } # unix_listener replication-notify { # mode = 0666 # #user = vmail # } #} # #service doveadm { # inet_listener { # port = 12346 # } #} # ##doveadm_port = 12346 #doveadm_password = XXXXXXX #replication_max_conns = 30 # and a mail_replica = tcp:host{a,b}:12346 configuration on each host so that they are pointing to eachother; This seems to work fine for most accounts, for example: I never experienced issues with this. However, several other accounts (with a large variety of clients) got duplicated emails. Looking with doveadm I only noticed that the numbers of the messages are closely related to eachother but one number incremented. So they cannot be deleted with the deduplicator function. The replication is provided over TCP only, the connection streams over an OpenVPN tunnel so that the contents are protected, the machines are located in different Datacenters but close to eachother. How can I determine why there are duplicated emails? What kind of messages should I specifically look for? Can I set this up for a few selected accounts instead of all accounts like it was currently? To make sure I do not make things worse for others then needs to be :-) The service had been disabled for the time being to prevent the other users from getting duplicated emails. Thanks for the advice in advance!

different mail location in different namespace
by Héctor Moreno Blanco 30 Oct '14

30 Oct '14

Hello everyone, We have Dovecot 2.1.6. With different Namespaces: ... mail_location = maildir:%h/Maildir ... namespace { separator = . prefix = inbox = yes type = private } namespace { inbox = no location = prefix = INBOX. separator = . hidden = yes type = private list = no } namespace { location = maildir:/buzon/archivo/%u/_ARCHIVO prefix = _ARCHIVO. hidden = yes separator = . type = private } We take the attribute "home directory" from the LDAP in the userdb attributes. We would like to modify this attribute for the Namespace ARCHIVO. For example, if a home directory is /buzon/buzon1/11111111, the mail location for ARCHIVO would be /buzon/archivo1/11111111. Is this modification possible without adding another attribute at the LDAP (just editing the attribute)? Thank you very much in advanced. Kind regards. Héctor Moreno.

Bug in the combination of Lazy_expunge and acl plugin
by Philipp Faeustlin 30 Oct '14

30 Oct '14

Hello Timo, Hello Dovecot Developers, Hello everyone on the list, I think I have some bug, because I haven't found a working configuration till now. I use latest dovecot 2.2.13 from the dovecot-ee repository, with acl and the lazy_expunge plugin. My configuration for shared folders work fine with lazy_expunge disabled. If I enable lazy_expunge and the user (named userA), which I'm testing with, got no shared folders, then lazy_expunge is working as supposed. Now I add some shared folder for example per doveadm: doveadm acl set -u userB(a)domain.de INBOX user=userA(a)domain.de lookup read write write-seen write-deleted insert expunge create After that every list command fails with: Fatal: lazy_expunge: Unknown namespace: '.EXPUNGED/' '.EXPUNGED/' is the name for the namespace of lazy_expunge. Easiest way for me to reproduce the error is: doveadm mailbox list -u userA(a)domain.de which results in: ----------------- Trash Drafts Sent doveadm(userA(a)domian.de): Fatal: lazy_expunge: Unknown namespace: '.EXPUNGED/' ------------------ I hope someone can confirm this behavior and or give me some hints to get rid of it.

Bug in fts (solr?, Maildir?) incorrect last_indexed_uid
by Karl O. Pinc 30 Oct '14

30 Oct '14

Hi, I thought I should document this. (Dovecot 2.2.9, see config at bottom.) I installed dovecot and then converted a number of mbox mailboxes to Maildir, and had a number of pre-existing Maildir mailboxes. I then installed the debian (wheezy) fts-solar and jetty packages, and tested my inbox using the "telnet localhost imap ... 3 SEARCH text "test" method as described on the dovecot wiki. Everything seemed to work. But when I used balsa to search a mailbox other than my inbox, I got no results. "doveadm dump" on the searched mailbox showed that "last_indexed_uid" to be the last uid of my inbox. Stopping dovecot, deleting out the dovecot-index* files, starting dovecot, and re-running "doveadm dump" showed a non-existant last_indexed_uid -- that is, last_indexed_uid did not show up in the dump output. Using the telnet method above to attempt to search again yielded no results, but this time (I think, I also tried various times with balsa) the last_indexed_uid value was that of the last uid in my trash mailbox. I don't believe I'd yet tried fts on my trash. Using balsa as an imap client the results were very consistent; every Maildir where "doveadm dump" returned no last_indexed_uid value had the last_indexed_uid set to that of the inbox's largest uid. Running "doveadm fts rescan -u foo" fixed the problem. (FWIW, now all the Maildirs seem to have a last_indexed_uid=0.)

Quota reporting
by Hanns Mattes 30 Oct '14

30 Oct '14

Hi, my main server will be upgraded from Dovecot 1.2something to 2.2. For testing I've installed a setup with postfix, handing malis as a relay via lmtp. So far it's up and running - really nice. AFAICS there's one issue left: Thunderbird and Kmail don't show the quota status. Using doveadm quota the information is shown correctly, even the user-specific values (coming from openldap) are set correctly. I think, I miss something obvious ... (and besides quota - any configuration hint is very welcome) linux:/etc/dovecot # doveconf -n # 2.2.15: /etc/dovecot/dovecot.conf # OS: Linux 3.7.10-1.40-desktop x86_64 openSUSE 12.3 (x86_64) auth_master_user_separator = * auth_mechanisms = plain login digest-md5 cram-md5 apop auth_verbose = yes mail_debug = yes mail_location = maildir:~/Maildir mail_plugins = " quota zlib fts fts_lucene trash" 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 ihave duplicate namespace inbox { inbox = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Sent { auto = subscribe special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } prefix = } passdb { args = /etc/dovecot/master-users driver = passwd-file master = yes pass = yes } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { fts_autoindex = yes fts_lucene = whitespace_chars=@. quota = maildir:User quota quota_exceeded_message = Storage quota for this account has been exceeded, please try again later. quota_grace = 100M quota_rule = *:storage=1000M quota_rule2 = Trash:storage=+10%% quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=80%% quota-warning 80 %u quota_warning3 = storage=75%% quota-warning 75 %u sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_max_redirects = 32 trash = /etc/dovecot/dovecot-trash.conf.ext zlib_save = gz zlib_save_level = 6 } postmaster_address = admin(a)93er.net protocols = imap pop3 lmtp sieve service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } } service lmtp { inet_listener lmtp { address = 127.0.0.1 port = 24 } user = vmail } service managesieve-login { inet_listener sieve { port = 4190 } inet_listener sieve_deprecated { port = 2000 } } service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 ssl = yes } } service quota-warning { executable = script /usr/local/bin/quota-warning.sh user = vmail } ssl_cert = </etc/dovecot/brueckokomplett2014.crt ssl_key = </etc/dovecot/brueckofrei2014.key userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } verbose_proctitle = yes protocol lmtp { mail_plugins = " quota zlib fts fts_lucene trash quota sieve" } protocol lda { mail_plugins = " quota zlib fts fts_lucene trash" } protocol imap { mail_plugins = " quota zlib fts fts_lucene trash quota imap_quota imap_zlib" } here is dovecot-ldap.conf.ext: hosts = 127.0.0.1 192.168.0.1 dn = cn=Manager,dc=dies,dc=jenes dnpass = ganzgeheim auth_bind = no base = ou=virtualmail,dc=dies,dc=jenes scope = subtree user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid,quota=quota_rule=*:\ storage=%$M user_filter = (&(objectClass=CourierMailAccount)(uid=%u)) pass_attrs = uid=user,userPassword=password,homeDirectory=userdb_home,uidNumber\ =userdb_uid,gidNumber=userdb_gid,quota=userdb_quota_rule=*:storage=%M pass_filter = (&(disableimap=FALSE)(objectClass=CourierMailAccount)(uid=%u)) iterate_attrs = uid=user iterate_filter = (objectClass=CourierMailAccount) default_pass_scheme = PLAIN Any ideas?

Renaming not supported across conflicting directory - why?
by Arkadiusz Miśkiewicz 30 Oct '14

30 Oct '14

I wonder what is point of checkign file/dir create mode like this? Here it makes problems since some folders have different permissions than others but both are accessible/writable by user. So renaming is possible (as renaming according to unix permissions). Yet dovecot artificially prevents this. /* if we're renaming under another mailbox, require its permissions to be same as ours. */ if (strchr(newname, mailbox_list_get_hierarchy_sep(newlist)) != NULL) { struct mailbox_permissions old_perm, new_perm; mailbox_list_get_permissions(oldlist, oldname, &old_perm); mailbox_list_get_permissions(newlist, newname, &new_perm); if ((new_perm.file_create_mode != old_perm.file_create_mode || new_perm.dir_create_mode != old_perm.dir_create_mode || new_perm.file_create_gid != old_perm.file_create_gid)) { mailbox_list_set_error(oldlist, MAIL_ERROR_NOTPOSSIBLE, "Renaming not supported across conflicting " "directory permissions"); return -1; } } -- Arkadiusz Miśkiewicz, arekm / ( maven.pl | pld-linux.org )

Sieve plus addressed mail filtering
by Peter Chiochetti 30 Oct '14

30 Oct '14

Today I learned, that to filter incoming plus addressed mail (user+tag@…) I had to deviate from the documentation. There it reads: if envelope :detail "to" "spam"{ fileinto "Spam"; } Instead I had to write: if address :is :detail "To" "tag"{ fileinto "Tagged"; } Dovecot version is 2.2.13-1+bigmichi1~precise+1 -- peter
