[Dovecot] Dovecot 2 fails after correct login
by Frank Walter 20 May '12

20 May '12

Hello I installed dovecot 2.0.9 (and dovecot-mysql!) on my Ubuntu 12.04 LTS root-server to work together with Postfix 2.9.1-4 After some struggle, I got Postfix's auth working, using dovecot for smtp-authentification with mysql. But dovecot himself is not working properly. When I connect, after giving plaintext password I read the error in the client (I connect for debug reasons with a dos-box on windows): telnet example.org 110 +OK Dovecot ready. USER me(a)example.org +OK PASS myplainpassword -ERR [IN-USE] Internal error occurred. Refer to server log for more information. If I do: ... PASS thisisthewrongpassword I get: -ERR Authentication failed. And this is the debug-log (I changed IP and names, server to 1.2.3.4 me to 5.6.7.8 server-name to example.org, my email to me(a)example.org) May 20 12:14:54 auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth May 20 12:14:54 auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libdriver_mysql.so May 20 12:14:54 auth: Debug: auth client connected (pid=25337) May 20 12:14:57 auth: Debug: client in: AUTH 1 PLAIN service=pop3 lip=1.2.3.4 rip=5.6.7.8 lport=110 rport=1731 resp=AGZyYW5jQGV3Ni5vcmcAMzE0MTU= May 20 12:14:57 auth-worker: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth May 20 12:14:57 auth-worker: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libdriver_mysql.so May 20 12:14:57 auth-worker: Debug: pam(me(a)example.org,5.6.7.8): lookup service=dovecot May 20 12:14:57 auth-worker: Debug: pam(me(a)example.org,5.6.7.8): #1/1 style=1 msg=Password: May 20 12:15:00 auth-worker: Debug: sql(me(a)example.org,5.6.7.8): query: SELECT email as user, password FROM view_users WHERE email='me(a)example.org'; May 20 12:15:00 auth: Debug: client out: OK 1 user=me(a)example.org May 20 12:15:00 auth: Debug: master in: REQUEST 4018667521 25337 1 ccd274c0359454ad3beae53ccb1cc03b May 20 12:15:00 auth: Debug: passwd(me(a)example.org,5.6.7.8): lookup May 20 12:15:00 auth: Debug: prefetch(me(a)example.org,5.6.7.8): passdb didn't return userdb entries, trying the next userdb May 20 12:15:00 auth-worker: Debug: sql(me(a)example.org,5.6.7.8): SELECT home, uid, gid FROM users WHERE username = 'me' AND domain = 'example.org' May 20 12:15:00 auth: Debug: master out: FAIL 4018667521 And with wrong password: ...

[Dovecot] Convert from ISO-8859-1 to UTF-8?
by Bjørn T Johansen 20 May '12

20 May '12

The server I am running Dovecot on is still using locale = ISO-8859-1 but I am thinking it is time to convert to UTF-8... Can I just use convmv to convert all the files in the mailboxes to UTF-8 or is there anything else I need to do? Do I need to run iconv to convert the content also or does dovecot/MUA fix this by it self? (i.e. they display the mail as encoded in ISO-8859-1) Regards, BTJ -- ----------------------------------------------------------------------------------------------- Bjørn T Johansen btj(a)havleik.no ----------------------------------------------------------------------------------------------- Someone wrote: "I understand that if you play a Windows CD backwards you hear strange Satanic messages" To which someone replied: "It's even worse than that; play it forwards and it installs Windows" ----------------------------------------------------------------------------------------------- -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

Re: [Dovecot] BEWARE: This list is being harvested for leads

I personally didn't mind a one-time notice from the dev's team that that are now offering paid commercial support. What if I WANTED it? I felt like it was a courtesy email from them to let me know that it's available. If those emails continue unsolicited, then it may start to feel like spam to me, but this did not. In general, I've actually been looking for ways to financially support good open source projects. I have worked with many & find that oftentimes, the ones with hood commercial support tend to be ones that have the manpower resources needed to quickly fix bugs, patch vulnerabilities, maintain a strong development schedule & give decent support through mailing lists & similar means. So when I received the email, immediately I thought: "Hmm. This may come in handy down the road, and would serve two purposes by giving me an easily justifiable means to support the project".

[Dovecot] Best way to change index location on mdbox
by Patrick Westenberg 20 May '12

20 May '12

Hi, right now my index directory is part of the users home directory: mail_home = /var/mail/%d/%n mail_location = mdbox:~/mdbox I want the indexes to be stored in a different location: mail_home = /var/mail/%d/%n mail_location = mdbox:~/mdbox:INDEX=/var/indexes/%d/%n If I just switch this setting and reload the configuration, no e-mails are shown to the user. After restoring the whole maildir I deleted all dovecot.index.*-files from that user and starting dovecot with the new index directory setting, I got the following error after connecting. I expected the index files to be regenerated but I got an error: May 18 23:11:12 imap(test(a)example.com): Panic: file mail-storage.c: line 787 (mailbox_check_mismatching_separators): assertion fail ed: (strncmp(vname, ns->prefix, ns->prefix_len-1) == 0) May 18 23:11:12 imap(test(a)example.com): Error: Raw backtrace: /usr/local/lib/dovecot/libdovecot.so.0(+0x4475a) [0x7f993f60875a] -> /usr/local/lib/dovecot/libdovecot.so.0(+0x447a6) [0x7f993f6087a6] -> /usr/local/lib/dovecot/libdovecot.so.0(i_error+0) [0x7f993f5df5bf] - > /usr/local/lib/dovecot/libdovecot-storage.so.0(mailbox_open_stream+0) [0x7f993f8ccca0] -> /usr/local/lib/dovecot/libdovecot-storage.so. 0(mailbox_open+0xf) [0x7f993f8cccbf] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(mdbox_storage_rebuild_in_context+0xb2b) [0x7f993f8 8eeab] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(mdbox_sync_begin+0x7ec) [0x7f993f88ce7c] -> /usr/local/lib/dovecot/libdovecot-st orage.so.0(mdbox_sync+0x46) [0x7f993f88cee6] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(mdbox_storage_sync_init+0x87) [0x7f993f88c fc7] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(mailbox_sync_init+0x31) [0x7f993f8cb851] -> /usr/local/lib/dovecot/libdovecot-stor age.so.0(mailbox_sync+0x27) [0x7f993f8cc387] -> /usr/local/lib/dovecot/libdovecot-storage.so.0(index_storage_get_status+0x28f) [0x7f993f8 ef41f] -> dovecot/imap(imap_status_get+0x7a) [0x41756a] -> dovecot/imap(cmd_status+0x14f) [0x40e85f] -> dovecot/imap(command_exec+0x3d) [ 0x41158d] -> dovecot/imap() [0x41050e] -> dovecot/imap() [0x4105ed] -> dovecot/imap(client_handle_input+0x135) [0x410815] -> dovecot/imap (client_input+0x5f) [0x41113f] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x36) [0x7f993f6148f6] -> /usr/local/lib/dovecot /libdovecot.so.0(io_loop_handler_run+0x9f) [0x7f993f61592f] -> /usr/local/lib/dovecot/libdovecot.so.0(io_loop_run+0x28) [0x7f993f614898] -> /usr/local/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f993f601023] -> dovecot/imap(main+0x2a4) [0x419364] -> /lib/libc.s o.6(__libc_start_main+0xfd) [0x7f993f280c8d] -> dovecot/imap() [0x408e89] How can I change the index directory without losing mails?

[Dovecot] wrong search results with fts_solr

[Dovecot] High level of pop3 popping causing server to become unresponsive
by Root Kev 19 May '12

19 May '12

Hello all, We have put Dovecot 2.1.4 on several of our production servers (CentOS, on Dell R710, with 20GB memory, dual CPU Quad-core). We have a single instance of Dovecot running and currently have several instances of Popa3d. When there are significant amount of popping from 2 mailboxes that dovecot that is popping from (500+ msgs in the mailboxes), the popping of the messages causes the boxes to become unresponsive. We use another application that connects to the Dovecot, downloads 2-10 messages, then processes them, then sends the delete command to Dovecot. When this issue occurs we are unable to become Root, or login again if we close our ssh connection. This only occures when Dovecot is doing the popping. If we only run the older Popa3d, this doesn't occur. We believe it is caused by the way dovecot is authenticating. We are using auth_mechanisms = plain passdb drive = shadow usedb driver = passwd args = blocking=yes If anyone could suggest what could be causing the login issue, we would appreciate any incite to fix it! Thanks, Kevin

[Dovecot] ..::MBOX ISSUE::..
by Alfonso Alejandro Reyes Jimenez 19 May '12

19 May '12

Hi everyone. I have a postfix working with sasl auth and dovecot, everything works fine. I just have 2 issues, the first is that if you add the IMAP mail accounts you can import all the mboxes on the /var/spool/mail/ which we don't want. The second issue is that there's no sent, trash and draft folder, so if we have imap we are not able to store those emails. Basically I would like to know how to fix both but the first one is the most urgent. I thought it was a postfix issue, but it seems not to be. Any ideas? Thanks in advance for your help.

[Dovecot] Authentication with AD and quick mbox question
by Kaya Saman 19 May '12

19 May '12

Hi, I'm attempting to implement Dovecot 2.1.3 built on a FreeBSD 8.2 64 bit system from ports. I had the servicve up and running on a local vbox demo which did a very simple Maildir format sytem which was situated in ~/Maildir. I would now like to expand the system and tie it to a Windows domain. What is the best way to go about doing this? Can Dovecot be directly tied in or do I need to tie the server in to the domain? This is my current dovecot.conf file - which of course I will tweak but as I am currently in the stage of building this is what I have so far: protocols = imap # It's nice to have separate log files for Dovecot. You could do this # by changing syslog configuration also, but this is easier. log_path = /var/log/dovecot.log info_log_path = /var/log/dovecot-info.log # Disable SSL for now. ssl = no disable_plaintext_auth = no # We're using Maildir format #mail_location = maildir:~/Maildir mail_location = mbox:/mail:INBOX=/mail/%u # If you're using POP3, you'll need this: #pop3_uidl_format = %g # Authentication configuration: auth_verbose = yes auth_mechanisms = plain passdb { driver = passwd-file args = /usr/local/etc/dovecot/passwd } userdb { # driver = static # args = uid=root gid=root home=/root/ driver = static args = uid=500 gid=500 home=/ZPOOL_1/%u } Is this correct to use mbox++ format and store under /mail/%u ?? Can anybody give me some advice? Regards, Kaya

[Dovecot] Migration between namespaces breaks outlook on mac's
by Mark Zealey 19 May '12

19 May '12

Hi there, We're running dovecot 1.1 on one set of servers with a courier-imap-like namespace configuration: namespace private { separator = . prefix = INBOX. inbox = yes } We're now migrating customers onto a dovecot-2 platform, switching from Maildir to sdbox (using dsync mirror) & changing the namespace at the same time.

[Dovecot] TLS X.509 CRLs
by Matthias-Christian Ott 18 May '12

18 May '12

Hi, according to the documentation file referenced by ssl_ca must contain the Client certificate CA and the corresponding CRL. Thus dovecot would have to receive SIGHUP to reload a new CRL. Did I understand this correctly? Regards, Matthias-Christian

[Dovecot] Getting Postfix Admin's DB to work with Postfix's/Dovecot's MySQL DB
by Femi Ajayi 18 May '12

18 May '12

Hi all, I followed the instructions here: http://library.linode.com/email/postfix/dovecot-mysql-centos-5 to configure Postfix to work with MySQL and Dovecot before discovering PostfixAdmin (I was searching for a visual tool for creating users). Since I had created MySQL database already for virtual domains and user mailboxes (following the instructions I linked to earlier) and PostFix admin's db too does the same. Question #1: is there anyway to make all these work with together for the creationg and use of virtual users/mailboxes? or is there another visual tool for creating virtual users/mailboxes? I had also installed Roundcube following the instructions on Roundcube's page: http://trac.roundcube.net/wiki/Howto_Install The questions now is: . #2. Roundcube came with its own database, which also stores user information. Is there a way to ensure that the user information is picked from the database created to work with Postfix (and not Roundcube's)? Thanks.

[Dovecot] Error in dovecot 2.0.13: "Too many levels of symbolic links"
by Tom Pawlowski 17 May '12

17 May '12

Hi all, I've run into an issue we have with dovecot versions 2.0.12 through 2.0.14 on latest CentOS 6.2 when dealing with Maildirs located on NFS partitions. Although I saw Mr. Egbert's thread, his resolution does not work on our end. When dealing with users with over 500 messages in any of their Maildir folders, they occasionally receive an error from the server: Internal error occurred. Refer to server log for more information. The corresponding log entries: dovecot: imap(user1): Error: readdir(/u1/user1/Maildir/.AUTO-DELETED-SPAM/new) failed: Too many levels of symbolic links dovecot: imap(user1): Error: readdir(/u1/user1/Maildir/.logwatch/new) failed: Too many levels of symbolic links dovecot: imap(user2): Error: readdir(/u2/user2/Maildir/cur) failed: Too many levels of symbolic links dovecot: imap(user2): Error: readdir(/u2/user2/Maildir/.Trash/new) failed: Too many levels of symbolic links dovecot: imap(user3): Error: readdir(/u1/user3/Maildir/.Trash/new) failed: Too many levels of symbolic links dovecot: imap(user3): Error: readdir(/u4/user3/Maildir/.AUTO-DELETED-SPAM/new) failed: Too many levels of symbolic links dovecot: imap(user4): Error: readdir(/u1/user4/Maildir/.AUTO-DELETED-SPAM/new) failed: Too many levels of symbolic links dovecot: imap(user4): Error: readdir(/u1/user4/Maildir/new) failed: Too many levels of symbolic links A 'find . -type l' shows there are absolutely no symbolic links to be found in those directories. Running readdir.c that Timo provided always returns errno == 0 on {cur,new} of all the directories reported in the logs. It does not occur consistently in production, but it does tend to occur to a fuzzy set of the same users on different partitions. We can replicate it every time in testing. The file count in these directories are all over the place, from less than a thousand to multiple thousands. However, it's hard to calculate what may have been in new prior to the clients processing/sorting that mail. It may have been more on the higher side than lower. The error tends to favor new over cur, but there are exceptions. The tests we have been trying: Create a new folder using alpine, save anywhere from 1000 to 10000 identical emails to the new folder. Change to that new folder, thus prompting the move from new to cur. The client receives the message and aborts the opening. Anywhere from 400-520 files are successfully moved each time. It takes numerous attempts to finally move all the files over--which I suspect some IMAP clients do, hence the inconsistent errors in production. We then create a brand new folder with the same amount of files and verify that the error is reproduceable--which it is. I'm leaning towards some sort of bug on the NFS client level, as Timo mentioned, but the odd thing is we were running this setup since early April and did not begin seeing these errors until early May--with user load being relatively consistent during that time. I would think the bug would have been evident before then. I'm also curious as to why dovecot is getting an ELOOP error code from it. Any ideas or pointers would be appreciated, sorry for the length. :) -- Tom Pawlowski OIT-CSS System Administrator office: Hill 145 email: tompru(a)jla.rutgers.edu phone: (732) 445-2634

[Dovecot] Migration between namespaces breaks outlook on mac's
by Mark Zealey 17 May '12

17 May '12

Hi there, We're running dovecot 1.1 on one set of servers with a courier-imap-like namespace configuration: namespace private { separator = . prefix = INBOX. inbox = yes } We're now migrating customers onto a dovecot-2 platform, switching from Maildir to sdbox (using dsync mirror) & changing the namespace at the same time. New namespace configuration looks like (as taken from http://wiki2.dovecot.org/Namespaces) # This is for courier-imap namespace compatability namespace { type = private separator = / prefix = inbox = yes } namespace { type = private prefix = INBOX. separator = . inbox = no hidden = yes list = no alias_for = } For 99% of clients this works fine eg thunderbird on first login after migration notices the folder structure has changed & automagically redownloads folders & emails.

[Dovecot] How to make Dovecot verbous
by Frank Walter 16 May '12

16 May '12

Hello I am struggling with Dovecot 2 (coming from Dovecot 1.0.10) with mysql Authentification for Postfix. I get errors when using it: dovecot: auth: Fatal: Unknown database driver 'mysql' dovecot: master: Error: service(auth): command startup failed, throttling But a first thing would be to log the real errors, if there are any, so I set in /etc/dovecot/conf.d/10-logging.conf auth_verbose, auth_verbose_passwords, auth_debug, auth_debug_passwords, mail_debug, verbose_ssl all to yes and I set: debug_log_path = /var/log/dovecot-debug.log but there is no logfile after restarting dovecot. How can I enable a (verbous) own Logfile in Dovecot? frank

I thought someone could make money coming up with an "unsend" and "untwitter" service that all it does is to queue the outgoing message for 5 minutes, during which the sender can re-consider and remove it from the queue. Sorot of like the kill-switch for live broadcasts. But as the saying goes, you can't make things foolproof, as they keep making better fools. As to the OP trying to determine whether an Email message has been read, an indirect and imperfect technique, used by spammers and marketing critters, is to web bug http://en.wikipedia.org/wiki/Web_bugs It works by placing innocuous individualized tags in HTML formatted Email e.g. "<img src="http://your.domain/?id={hash}>" that downloads a 1x1 dot). You can then correlate web logs with the hashes to see which messages got rendered. A hit does not necessarily mean it got read, and the absense does not mean it was ignored, but it's better than nothing. If you value your privacy, turn off HTML rendering on your Email reader.

[Dovecot] plugin: Don't allow deleting the last instance of a mail
by Timo Sirainen 16 May '12

16 May '12

Before beginning to code it, does anyone have any related ideas that could be useful before starting it? Mainly what I'm intending to do is to write a plugin for mdbox storage that allows users to expunge mails in a specific namespace only if there are other instances for the mail. So basically: * Users can't accidentally delete mails (in shared mailboxes) * Users can still move mails within folders For v2.1 this can be implemented only to a specific storage backend, so at least for now only mdbox will support it. Maildir and sdbox support would also be possible by looking at hard link counts. Race conditions would allow deleting the mails, but that's unlikely to be an issue since the main point is to avoid accidental deletions that shouldn't be attempted in the first place anyway.

[Dovecot] stats + fts squat plugins, indexer-worker error on message indexing
by David Warden 16 May '12

16 May '12

On RHEL 6.2 + dovecot 2.1.5 with the stats and fts (squat) plugins enabled and each user having their own uid on the system I get the following error in the logs when the indexer-worker process indexes some messages: Apr 25 09:56:19 wardentest3 dovecot: imap-login: Login: user=warden, method=PLAIN, rip=137.238.60.164, lip=137.238.2.240, lport=1993, mpid=19464, encryption=TLS Apr 25 09:56:26 wardentest3 dovecot: service=indexer-worker user=warden rip= Indexed 12 messages in INBOX Apr 25 09:56:26 wardentest3 dovecot: service=indexer-worker user=warden rip= Error: open(/proc/self/io) failed: Permission denied Apr 25 09:56:29 wardentest3 dovecot: service=imap user=warden rip=137.238.60.164 Disconnected: Logged out bytes(in/out)=46/780 What I did to generate the above was remove the squat indexes for my Inbox then log in via telnet and search for a string in my Inbox, which forced an index of the messages in my Inbox. Based on http://wiki2.dovecot.org/Services#indexer-worker it seems like this is because the indexer-worker process is created as root but at the time of indexing the indexer-worker drops privs to the mail user. In /proc/<indexer-worker pid>/, io is mode 0400 and owned by root, so it makes sense that the mail user would be unable to read that file. The strange thing is it looks like the stats are still collected (unless I am reading the output of the stats dump incorrectly): [root@wardentest3 mailtest]# doveadm stats dump -s /var/run/dovecot/mailtest/stats command user=warden cmd args session user last_update user_cpu sys_cpu min_faults maj_faults vol_cs invol_cs disk_input disk_output read_count read_bytes write_count write_bytes mail_lookup_path mail_lookup_attr mail_read_count mail_read_bytes mail_cache_hits select inbox 27fb87218302984f084c0000ae899e04 warden 1335362182.950250 0.000000 0.000000 172 0 46 0 0 12288 13 7883 4 381 0 0 0 0 0 search text "warden" 27fb87218302984f084c0000ae899e04 warden 1335362186.588023 0.001000 0.000000 32 0 4 1 0 0 4 108 1 43 0 0 0 0 0 logout 27fb87218302984f084c0000ae899e04 warden 1335362189.161790 0.000000 0.000000 1 0 0 3 0 0 1 108 3 157 0 0 0 0 0 This obviously isn't a show-stopper but if this is causing stats to be incorrect it would be great if this could be fixed. -David Warden My doveconf -n: # 2.1.5: /etc/dovecot/mailtest/dovecot.conf doveconf: Warning: service auth { client_limit=4096 } is lower than required under max. load (12288) doveconf: Warning: service anvil { client_limit=4096 } is lower than required under max. load (12291) # OS: Linux 2.6.32-220.7.1.el6.x86_64 x86_64 Red Hat Enterprise Linux Server release 6.2 (Santiago) nfs auth_cache_negative_ttl = 0 auth_cache_size = 16 M auth_gssapi_hostname = $ALL auth_krb5_keytab = /etc/dovecot/mailtest.combined.keytab auth_master_user_separator = * auth_mechanisms = plain login gssapi auth_username_format = %Ln base_dir = /var/run/dovecot/mailtest/ default_client_limit = 4096 default_process_limit = 4096 deliver_log_format = msgid="%m" subject="%s" from="%f" size=%p result="%$" first_valid_uid = 0 hostname = mailtest.geneseo.edu instance_name = mailtest lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes login_log_format_elements = user=%u method=%m rip=%r lip=%l lport=%a mpid=%e encryption=%c mail_fsync = always mail_location = maildir:/Mail/mailhome/%Ln/mailtest/Maildir:CONTROL=/Mail/mailhome/%Ln/mailtest/.dovecot-control:INDEX=/Mail/mailhome/%Ln/mailtest/.dovecot-index mail_log_prefix = "service=%s user=%u rip=%r " mail_nfs_index = yes mail_nfs_storage = yes mail_plugins = zlib quota mail_log notify fts fts_squat stats maildir_very_dirty_syncs = yes 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 mbox_write_locks = fcntl mmap_disable = yes namespace default { inbox = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Junk { auto = no special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } prefix = separator = . type = private } passdb { args = /etc/dovecot/passwd.masterusers driver = passwd-file master = yes } passdb { args = cache_key=%u dovecot driver = pam } plugin { fts = squat mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename flag_change append mail_log_fields = uid box msgid size from subject flags mail_log_group_events = yes quota = maildir:User quota quota_exceeded_message = Quota exceeded (mailbox for user is full).

[Dovecot] [Plugin dev] First-time-only cache lock failure
by John G 15 May '12

15 May '12

Hi This is a question related to plugin developement on Dovecot 2.1.4. I'm currently implementing a dovecot plugin that retrieves mails from a corporate server through an internal protocol. The plugin is very similar to the pop3c storage (lib-storage/index/pop3c). The plugin has to map original server UIDs to IMAP UIDs, using MAIL_CACHE_POP3_UIDL cache field the same way pop3c does. So, I've got a function similar to pop3c_sync_messages(), performing several mail_index_append() and mail_cache_add() calls. The problem is that on the first sync, when the index and cache files don't exist yet, there's a failure writing data in cache. The call to mail_index_sync_commit()\mail_cache_transaction_commit() fails because of mail_cache_transaction_lock(). The index and cache files are properly created, but the cache doesn't contain the MAIL_CACHE_POP3_UIDL values. It works properly on the second sync, the MAIL_CACHE_POP3_UIDL field being properly saved. Would you have some ideas on what could be wrong here? Thanks, John

[Dovecot] default mail quota when using per user quota
by Andreas Helmcke 14 May '12

14 May '12

Hello, using dovecot 2.1 and per user mail quota via ldap is there a way to have a default quota which gets used, if the "quota" field in ldap is not set? I tried with: plugin { quota = maildir:User quota quota_rule = *:storage=3G } userdb { args = /etc/dovecot/dovecot-ldap.conf driver = ldap } and in dovecot-ldap.conf: user_attrs = dcMailQuota=quota_rule=*:storage=%$ but with this configuration the mail quota /allways/ gets loaded from ldap resulting in users without dcMailQuota attribute having no quota at all. Greetings Andreas

[Dovecot] doveadm not working
by Christian Rößner 14 May '12

14 May '12

Hi, I know I must have done some misconfiguration, but I do not know where to start searching for. All began when looking at my weekly cron message, where doveadm purge -A is run. That fails. So I tried doveadm quota -A as well, which several weeks ago was working perfectly. Example: doveadm quota get -A doveadm(root): Error: User listing returned failure doveadm: Error: Failed to iterate through some users Username Quota name Type Value Limit % All I see in the logs is: May 13 13:03:20 mx0 dovecot: auth: Error: auth worker: Aborted request: Lookup timed out May 13 13:03:21 mx0 dovecot: auth-worker(26753): Error: LDAP: ldap_start_tls_s() failed: Connect error May 13 13:03:21 mx0 dovecot: auth-worker(26753): Error: LDAP: ldap_start_tls_s() failed: Can't contact LDAP server Dovecot itself works. Only doveadm does not. My LDAP is using SASL/EXTERNAL. Certs are in standard folders under /etc/ssl/{certs,private} (see below). I guess that "some" user (but which?) tries to read the certs but is disallowed. Can somebody help me please to fix my permissions on that (private used) mail server? Is my "vmail" user required?

[Dovecot] Log files
by Chris Lasater 14 May '12

14 May '12

Hi, I just started using Dovecot and was trying to create separate logs instead of using syslog. Is there a way to get the file permission to be something other then root? I have tried the below configuration and it does not seem to change anything. The log process does change to a new user, but it still creates and writes as root. Whenever I test a new setting I delete all the current logs so they will have to be recreated to make sure it does not just keep the previous permissions. I also dont see much documentation on the service log. according to dovecot -a there are a good number of options, but I dont see any information about them. Here are my logging settings below and I am running 2.1.6 and tried on 2.1.5. ### Logging info_log_path = /home/user/dovecot/logs/dovecot_info.log log_path = /home/user/dovecot/logs/dovecot.log debug_log_path = /home/user/dovecot/logs/debug.log service log { user = user unix_listener log-errors { group = user2 mode = 0620 user = user } } Thanks, Chris

[Dovecot] dovecot report W value error and Corrupted index cache file
by 甄东宇 14 May '12

14 May '12

Hello everybody, I have a problem and no idea. Yesterday Dovecot.log report: Warning: Fixed a duplicate: /opt/*/cur/<time>.M*.<domain>,S=*,W=*:2,S -> <time>.M*.<domain> Now Dovecot.log report: Error: FETCH [ ] for mailbox INBOX UID 10546 got too little data: 79850 vs 81231 Error: Maildir filename has wrong W value: /opt/DIR/DOMAIN/USER/cur/1281317869.M*.*,S=79569,W=81231:2,S~ Error: Corrupted index cache file /opt/DIR/DOMAIN/USER/dovecot.index.cache: Broken virtual size for mail UID 10546 A few days ago, we used a new machine for mail server (and we used maildir format with dovecot-1.2.0).In fact ,we used iRedmail on CentOS5. And last week, I copy some mail data from old machine to new one through SCP and CP command. It worked well. Yesterday, I copy the mail data from old machine to new one through RSYNC. I guess maybe the errors have a relationship with rsync, because the new machine open SELinux and the rsync data error. Although the files were copyed to /cur directory , it seemed to appear the same mail file. Now,I receive some BLANK mails by pop3 of OutLook2007 . There are not any Header and any Body( Totally BLANK). Outlook show they are 760B size. I am confusing for this problem. Please help me. Thank you.

[Dovecot] userdb namespace settings bug
by Alexander 'Leo' Bergolth 14 May '12

14 May '12

Hi! Since upgrading to 2.1.6, setting namespaces via environment variables using a imap-postlogin-script *sometimes* doesn't work. Sometimes, the prefix of a namespace isn't set correctly, but is set to an empty string, which leads to the following error: namespace configuration error: Duplicate namespace prefix: "" However, the environment is set correctly, the error seems to occur when parsing the environment. See the attached log: The postlogin-script sets the environment variables attached as dovecot-postlogin-environment.txt. (dumped from postlogin script via env) However, the variable "NAMESPACE/S-GSD/PREFIX=Shared/GSD/" gets parsed as: plugin/namespace/s-gsd/prefix=Shared/GSD/ See the error message: Unknown userdb setting: plugin/namespace/s-gsd/prefix=Shared/GSD/ After restarting dovecot, the same configuration sometimes works correctly. I'd greatly appreciate your help! Unfortunately I have done the upgrade on a production system, so the issue is quite serious for me.. Will downgrading to 2.0 work? (Index-files, etc?) Thanks, --leo -- e-mail ::: Leo.Bergolth (at) wu.ac.at fax ::: +43-1-31336-906050 location ::: IT-Services | Vienna University of Economics | Austria

[Dovecot] dovecot wants to access my music directory
by Ian Pilcher 14 May '12

14 May '12

I am getting an SELinux error every time dovecot starts, because it is trying to access my music directory (/srv/music). I've read the doveadm-mount man page, and tried: doveadm mount add /srv/music ignore but it didn't make any difference. Now, I certainly didn't tell dovecot to access this directory, so how can I tell it *not* to do so. This is dovecot-2.1.6-2.fc17.x86_64 on Fedora 17 Beta, BTW. Thanks! -- ======================================================================== Ian Pilcher arequipeno(a)gmail.com "If you're going to shift my paradigm ... at least buy me dinner first." ========================================================================

do we really need "session=<ugAua+i/ewBUcit1>" additional to proxy log-lines? until this change it was possible on a 24" screen with "tail -f /var/log/maillog" to watch without linebreaks, now each proxy line breaks PLEASE reconsider such changes!

[Dovecot] index IO patterns
by Cor Bosman 12 May '12

12 May '12

Hey all, we're in the process of checking out alternatives to our index storage. We're currently storing indexes on a NetApp Metrocluster which works fine, but is very expensive. We're planning a few different setups and doing some actual performance tests on them. Does anyone know some of the IO patterns of the indexes? For instance: - mostly random reads or linear reads/writes? - average size of reads and writes? - how many read/writes on average for a specific mailbox size? Anyone do any measurements of this kind? Alternatively, does anyone have any experience with other redundant storage options? Im thinking things like MooseFS, DRBD, etc? regards, Cor

[Dovecot] /var/run/dovecot folder gets deleted on server reboot? ubuntu 10.10
by jacques 11 May '12

11 May '12

Hi After rebooting my server connections to the mail system set up there failed - on closer inspection no dovecot process was running or got started. When running as root /usr/share/sbin/dovecot -c /etc/dovecot/dovecot.conf got error on console /var/run/dovecot/auth-master could not be opened and found no /var/run/dovecot folder!. Is there better script to place in /etc/init.c/ to start dovecot (which will not fail silently?) Any idea what would remove the folder on ubuntu 10.10, running dovecot 2.1.5 and postfix 2.1.7? Any suggestions? Jacques

[Dovecot] Request for help with dovecot.conf file: configured to work with MySQL and Postfix.
by Femi Ajayi 10 May '12

10 May '12

Greetings, I have CentOS 6.2 running on our server with a VPS provider (Linode.com) I need to configure Postfix, dovecot, MySQL to work for virtual domains (multiple domains on our server). The only instructions for setting up Email with Postfix, Dovecot and MySQL my host provides is for the configuration on CentOS 5 which is here: http://library.linode.com/email/postfix/dovecot-mysql-centos-5 , I followed it for the installation/configuration of Email with Postfix, Dovecot and MySQL on our CentOS 6.2 Everything seemed to work fine until I got to the editing of the dovecot.conf file. The guide on the Linode Library provides instructions for Dovecot 1.x, while the newer versions of CentOS (CentOS 6) , apparently use Dovecot 2.x. The config file format has changed, so the one in the guide is no longer applicable, and as a result, I got a errors.. I would therefore appreciate it greatly if someone with a copy of the Dovecot 2.x dovecot.conf file configured to work with MySQL and Postfix (for handling mails for multiple domains) could share it with me. You could get a better understanding of the problem if you take some time to look at the instructions I followed so far: http://library.linode.com/email/postfix/dovecot-mysql-centos-5 ..and also the forums where I had previously sought help: http://forum.linode.com/viewtopic.php?p=50603#50603 http://www.linuxquestions.org/questions/showthread.php?p=4672839#post4672839 Thanks in anticipation of your help.

[Dovecot] Thunderbird log-in --->Authentication failed - password in uppercase in log files
by jacques 10 May '12

10 May '12

Hi I use dovecot 2.1.5 with postfix, amavis, spamassasin, mysql, virtual domains only. Dovecot being used for SASL authentication, and delivery. When I connect via telnet to port 25 or with smtp and try to do auth plain with mmencode connection string authentication works fine. I can send and recieve messages, and relay works as well. Trying to set up thunderbird to connect to this server I get problems - seems as if the password is resolved proper from the database (use postfixadmin), but then compares an upper case version of my password in the MD5-CRYPT() call to the password string obtained from the database. I do see the base64 encoded connection string in dovecot log though.

[Dovecot] Enforcing Dovecot Quotas
by tcsmith1978 10 May '12

10 May '12

Hello, I have been looking at enforcing quotas for users of my mail system (postfix and Dovecot v1.2). Have tried to follow a few tuts on the web but its not having the desired effect. Essentially I can still send and receive mail on an account that I believe has had its quota exceeded. In my main.cf, I have: userdb sql { args = /etc/dovecot/mysql/dovecot-mysql.conf } passdb sql { args = /etc/dovecot/mysql/dovecot-mysql.conf } and... protocol lda { mail_plugins = quota } protocol imap { mail_plugins = quota imap_quota } plugin { quota_exceeded_message = You have exceeded the maximum quota for your mailbox } the dovecot sql (mysql) file has the following query for pulling out user ids and quotas etc: user_query = SELECT maildir, mymailuser as uid, mymailgroup as gid,concat('maildir:storage=',quota) as quota FROM virtual_mailbox WHERE username = '%u' I have set one of my users to have a quota of 1 (so one byte I believe) so it should be over the limit pretty much immediately. Looking at the logs I can see that the system is picking up on the quota limit but doesn't seem to enforce it. Apr 27 10:29:02 deliver(test(a)testdomain.com): Info: auth input: quota=maildir:storage=1 Apr 27 10:29:02 deliver(test(a)testdomain.com): Info: Quota root: name=storage=1 backend=maildir args= Any ideas?

[Dovecot] dovecot and systemd
by Michal Hlavinka 09 May '12

09 May '12

Hi all, dovecot supports systemd socket activation. Together with standard unit activation (like old sysv init script), there are two ways how to configure dovecot(only interface:port, not whole configuration). This can result in situation where those configurations does not say the same. Question is what should happen then? For example, lets have dovecot configured to listen for imap(s) and lets have systemd dovecot socket configured to listen for all protocols - pop3(s) and imap(s). When dovecot is configured to start on boot, systemd will start it and dovecot will listen on imap(s) ports. But when dovecot.socket is enabled, it'll listen on pop3(s) too and when new pop3 connection comes, it'll pass it to dovecot and dovecot will serve it. The question is: Should this happen? What exactly should happen when dovecot.conf does not match dovecot.socket configuration? Michal
