[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] 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. 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. However I have noticed some really strange messages in the logs which seems to be related to customers running outlook on macos. When they login after migration they are generating commands like: dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 1 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 1 1 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 1 1 1 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 1 1 1 1 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 1 1 1 1 1 ... this goes on a long time and we've not yet found a solution other than delete the imap config on their outlook and reconfigure. Does anyone have any idea why this might be happening, or if there is a way we can somehow have old namespaces for old customers, new namespaces for new customers (we are using sql login code so should be possible to do something like this in theory I think?) Thanks, Mark

[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. However I have noticed some really strange messages in the logs which seems to be related to customers running outlook on macos. When they login after migration they are generating commands like: 2012-05-07T00:04:43+01:00 imap-03 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 2012-05-07T00:05:38+01:00 imap-03 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 2012-05-07T00:06:44+01:00 imap-03 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 2012-05-07T00:07:33+01:00 imap-03 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 1 2012-05-07T00:08:42+01:00 imap-03 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 1 1 2012-05-07T03:09:00+01:00 imap-03 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 1 1 1 2012-05-07T03:09:08+01:00 imap-03 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 1 1 1 1 2012-05-07T03:10:09+01:00 imap-03 dovecot: imap(xxxx): Mailbox created: INBOX 1 1 1 1 1 1 1 1 1 1 1 1 ... this goes on a long time and we've not yet found a solution other than delete the imap config on their outlook and reconfigure. Does anyone have any idea why this might be happening, or if there is a way we can somehow have old namespaces for old customers, new namespaces for new customers (we are using sql login code so should be possible to do something like this in theory I think?) Thanks, Mark

[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

I've spent the past three hours searching google, but can't find even a hint at what's wrong with my server. As far as I can tell, this is the only thing that has failed after bringing the server back up when power was restored. Can anyone help me figure out what is wrong?

[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

Hello everybody, I have a problem and no idea.

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?)

[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." ========================================================================

[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] Postfix Query
by Tim 10 May '12

10 May '12

Hello, Another question!! Was just trying to sort out mail delivery to subdomains. I set up my system so that I have a mail address of tim(a)subdomain.example.com. I've sorted out Postfix to correctly identify this and pass on to Dovecot for delivery but Dovecot doesn't seem to deliver where I want it to. Ideally I would like to have a structure so that mail is delivered to /var/mail/example.com/subdomain/user My users are stored in MySQL and they are being pulled out correctly, but dovecot is delivering to /var/mail/subdomain.example.com/tim Looking at my logs it seems that the mail location is being picked up not being acted on... May 10 21:51:20 auth(default): Info: master out: USER 1 tim(a)subdomain.example.com maildir=example.com/subdomain/tim uid=mailuser gid=mailgroup quota_rule=*:bytes=2147483647 ...a bit further down... May 10 21:51:20 deliver(tim(a)subdomain.example.com): Info: auth input: maildir=example.com/subdomain/tim ...then further down it seems to change all of a sudden... May 10 21:51:20 deliver(tim(a)subdomain.example.com): Info: maildir: data=/var/mail/subdomain.example.com/tim/Maildir May 10 21:51:20 deliver(tim(a)subdomain.example.com): Info: maildir++: root=/var/mail/subdomain.example.com/tim/Maildir, index=, control=, inbox=/var/mail/subdomain.example.com/tim/Maildir Bit confused!

[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 2.1.6, with lmtp_save_to_detail_mailbox=yes recipient_delimiter=+ messages addressed to "user+detail@domain" are always delivered to INBOX regardless if "detail" mailbox already exists or lda_mailbox_autocreate=yes.

[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

[Dovecot] acls not copied when creating subfolder of private INBOX

Using brand new dovecot 2.1.5 I still have a problem with the inheritance of acls. Setting: - maildir with private INBOX and public folders. - users maildir directory (/home/mail/user/ahelmcke) contains dovecot-acl file - public folders root directory (/home/mail/Fax) contains dovecot-acl file When creating a subfolder of the public folder the dovecot-acl files gets copied to the subfolders directory as expected.

Re: [Dovecot] Dovecot for POP3S proxying

Dovecot is installed but actually I just use auth module (for postfix authentication). In your dovecot.conf example, I don't see the "proxy" command ?

If you already have dovecot running in proxy mode it's easy to add pop3s. If not, see http://wiki2.dovecot.org/PasswordDatabase/ExtraFields/Proxy See http://wiki2.dovecot.org/Services search the page for pop3s.

[Dovecot] IMAP NOTIFY extension

your work on NOTIFY was brought to my attention, and I see it hasn't been changed in two months, a week after you announced it. a few users and some mail admins have been wanting something like this for k9 mail, which I help develop. what is the current status? is it worth installing and starting work in getting k9 to support it yet? I'd offer help on your end, but I just know java and perl. c code usually confuses me (i keep meaning to learn, but...). thanks! -ashley -- Sent from my Android phone with K-9 Mail.

[Dovecot] courier to dovecot
by Grafibit Rendszergazda 07 May '12

07 May '12

Dear All, I know there were many threads on this topic. I was searching the archive and the net also, but did not find a solution on my problem. I hope you can help me. I am migrating from an old server using courier to a new server with dovecot and i can not manage to have the same uids after the migration. After copying the message files from the old server to the new, and executing the script from the wiki page the messages are still re-downloaded by the mail clients. After telnet and logging in to the old server port 110, I got the following on the command *uidl*: 1 UID377-1278276092 2 UID387-1278276092 3 UID394-1278276092 4 UID498-1278276092 5 UID499-1278276092 6 UID564-1278276092 On the new server i set up the *pop3_uidl_format = UID%u-%v* because it seems for me that the old server is using the same uidl format. Either if i execute the /./courier-dovecot-migrate.pl --to-dovecot --recursive --convert /command or i don't the uidls on the new server won't be the same. Both the %u and %v numbers are differ. Please give me any hints how to continue the investigation to have a successful migration.

Yes, that's possible. The IMAP/POP3 servers behind Dovecot director wouldn't even need to be Dovecots at all. Although you really want to use v2.1 director since it has a lot of fixes compared to v2.0.

[Dovecot] Proxying for some users and having the rest local?
by Dr Josef Karthauser 07 May '12

07 May '12

I'm migrating a load of mailboxes from cyrus to a new dovecot server. What I'd like to do is to switch the DNS to dovecot, and set things up so that all old imap mailboxes are accessed through the dovecot proxy. That way I can migrate them one at a time independent of DNS issues. I've got a load of users specified in mysql, and that configuration works well for local mailboxes. How do I configure things so that I can switch proxy access on and off? What's I've got so far is: password_query = SELECT user, domain, password, "masteruser" as master, "masterpass" as pass, proxy, "remoteimap.server" as host FROM mailboxes \ WHERE user = '%n' AND isMailbox AND active AND domain = '%d' I imagined that I could switch the proxy per user by setting proxy='n' or proxy=null for any users that want to be local, and proxy='y' for any users that I want to forward on to the original server. It doesn't appear to work that way though. Irrespective of the proxy value dovecot appears to try and proxy all users. What am I doing wrong? I can't work it out from the docs, and the source will take quite a bit of studying to get to the bottom of it all. Thanks :), Joe

[Dovecot] v2.1.6 released

07 May '12

http://dovecot.org/releases/2.1/dovecot-2.1.6.tar.gz http://dovecot.org/releases/2.1/dovecot-2.1.6.tar.gz.sig * Session ID is now included by default in auth and login process log lines. It can be added to mail processes also by adding %{session} to mail_log_prefix. + Added ssl_require_crl setting, which specifies if CRL check must be successful when verifying client certificates. + Added mail_shared_explicit_inbox setting to specify if a shared INBOX should be accessible as "shared/$user" or "shared/$user/INBOX". - v2.1.5: Using "~/" as mail_location or elsewhere failed to actually expand it to home directory. - dbox: Fixed potential assert-crash when reading dbox files. - trash plugin: Fixed behavior when quota is already over limit. - mail_log plugin: Logging "copy" event didn't work. - Proxying to backend server with SSL: Verifying server certificate name always failed, because it was compared to an IP address.

[Dovecot] Shared namespace
by Daniel L. Miller 07 May '12

I'm not sure what's triggered it - I THINK it has something to do with a force-resync, but not sure. I'm no longer viewing my full list of shared mailboxes. I used to have a number of users shown - they had all had their ACL's set individually and were shown in the list. "doveadm acl debug" shows they SHOULD be shown - at least I think so, as the output for the mailboxes that DO appear is identical for those that don't. Where should I look for breakage? -- Daniel

Given the above, and SIS - if the backup is performed in the same spool, i.e. original is /var/mail/domain/user, backup is /var/mail/domain/user-new - will this result in any problems with SIS? If after the pack and rename operation, the old mail tree is simply deleted - will that leave SIS files unreferenced if the user later deletes the messages from their active store? -- Daniel

[Dovecot] Authentication process holding open filehandles
by George Barnett 07 May '12

07 May '12

Hi, We're using dovecot to provide pop3 for a number of mailboxes. The setup is pretty simple: Each user / domain has a mailstore in /data/mailstore/<domain>/<user>/Maildir (backed by NFS). Passwords are in simple passwd-file format in the top level domain directory eg: # cat /data/mailstore/foo.com/.passwd user:{plain}password The passdb setup looks like this. passdb { args = username_format=%n /data/mailstore/%d/.passwd driver = passwd-file } The problem we're having is that when we want to remove a domain from the system and we go to rm -rf /data/mailstore/<domain>/ we are unable to because the auth process is still holding onto the file handles for the password file. Can somebody suggest an alternative pattern that I could use for storing password files? Ideally, we'd avoid one large file to prevent locking issues and would also keep the passwd-file setup since it's simple. It would be possible to have the password files in a separate dir, but over time I'm guessing that would lead to nfs turds? Easy to clean up I suppose, but maybe there's a simpler solution I'm missing? George

[Dovecot] per user sieve after filters

Hello, Thanks for dovecot, as it's still the best mail server. I'd like to use per users sieve_after scripts. Can I put in my dovecot config file, something like that: sieve_after = %h/Mails/Sieve/After/ It would be very useful for me, as I'd like to add vacation script to be executed from this place. Kind regards, André.

[Dovecot] Shared INBOX change in v2.1.6?
by Timo Sirainen 04 May '12

04 May '12

Previously Dovecot has shown shared INBOX like: * LIST (\HasChildren) "/" "shared/tss2" * LIST (\HasNoChildren) "/" "shared/tss2/INBOX" * LIST (\HasNoChildren) "/" "shared/tss2/foo" The last change in hg makes it return simply (same as with Cyrus): * LIST (\HasChildren) "/" "shared/tss2" * LIST (\HasNoChildren) "/" "shared/tss2/foo" This behavior could be made optional, but does anyone actually want it to work the old way (and why)? I'd rather not add an option that isn't useful to anyone. I think older Dovecot versions have allowed opening both shared/tss2 and shared/tss2/INBOX, but at least in v2.1 that code was broken. With the last change it's still possible to open both of them, the shared/tss2/INBOX just isn't visible in LIST output.

[Dovecot] dovecot sasl with postfix: SASL LOGIN authentication failed: Connection lost to authentication server
by David Jonas 04 May '12

04 May '12

When using dovecot (2.1.5) sasl with postfix (2.8.4) behind nginx smtp proxy I am seeing a ton of errors of the form: postfix/smtpd[7731]: warning: unknown[192.168.0.6]: SASL LOGIN authentication failed: Connection lost to authentication server Nothing is printed by dovecot in the logs regarding the error. It seems that dovecot just hung up on postfix. (side note: no, can't use xclient in nginx/postfix. But perhaps soon.) After much digging I thought I solved it with: login_trusted_networks = 172.20.20.0/24 mail_max_userip_connections = 0 This seems safe enough because dovecot is only providing sasl to postfix, no connections to the outside world. But the error is still happening. # doveadm penalty IP penalty last_penalty last_update 172.20.20.61 1 2012-04-30 19:15:56 19:15:56 strace on the anvil process shows a lot of GETs and INCs: 18:54:06 read(14, "PENALTY-GET\t172.20.20.61\n", 397) = 25 <0.000016> 18:54:06 write(14, "1 1335837245\n", 13) = 13 <0.000029> A two minute survey showed penalty distribution: 0: 60% 1: 15% 2: 18% 3: 8% Finally I just disabled penalties with the info from http://www.dovecot.org/list/dovecot/2011-December/062631.html and that seemed to do it. Is there a better way? This took me a long time to run down so I tried to make this message detailed enough that others with similar problems will stumble upon it.

[Dovecot] doveadm mailbox: rc=0 on error

Hi all, I use "doveadm mailbox mutf7 -7 $folder" to convert imap foldernames to UTF-8. If $foldername is not mUTF-7 encoded, doveadm returns "doveadm(root): Error: Mailbox name not valid mUTF-7: $folder" This errormessage is printed on stderr but the returncode of doveadm is zero. I tested with dovecot-2.0.* and dovecot-2.1.* # all right: $ doveadm mailbox mutf7 -7 'gr&APw-n'; echo $? grün 0 # also all right, no mUTF-7 encoded folder: $ doveadm mailbox mutf7 -7 'gruen'; echo $? gruen 0 # wrong $ doveadm mailbox mutf7 -7 'grün'; echo $? doveadm(root): Error: Mailbox name not valid mUTF-7: grün 0 Would be nice if doveadm exit with an errorcode != 0 in that case.

I asked about log synch error back in March and have (repeatedly) deleted all .imap files but the errors continue. # 2.1.1: /usr/etc/dovecot/dovecot.conf # OS: Linux 2.6.33.5-desktop-2mnb i686 Mandriva Linux 2010.2 mail_access_groups = mail mail_location = mbox:~/Mail:INBOX=/var/spool/mail/%u 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 namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap pop3 lmtp sieve sieve ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } protocol lmtp { mail_plugins = sieve } protocol lda { mail_plugins = sieve } Apr 30 09:00:12 server dovecot: imap(john): Error: Log synchronization error at seq=2,offset=929952 for /home/john/Mail/INBOX/.imap/Archive/dovecot.index: Extension header update points outside header size Apr 30 09:00:12 server dovecot: imap(john): Error: Log synchronization error at seq=2,offset=548744 for /home/john/Mail/INBOX/.imap/Davies/dovecot.index: Extension header update points outside header size Apr 30 09:00:12 server dovecot: imap(john): Error: Log synchronization error at seq=2,offset=541084 for /home/john/Mail/INBOX/.imap/FieldNET/dovecot.index: Extension header update points outside header size Apr 30 09:00:12 server dovecot: imap(john): Error: Log synchronization error at seq=2,offset=539768 for /home/john/Mail/INBOX/.imap/Invoices Out/dovecot.index: Extension header update points outside header size Apr 30 09:00:12 server dovecot: imap(john): Error: Log synchronization error at seq=2,offset=492896 for /home/john/Mail/INBOX/.imap/Lawrence and Hanson/dovecot.index: Extension header update points outside header size Apr 30 09:00:12 server dovecot: imap(john): Error: Log synchronization error at seq=2,offset=530300 for /home/john/Mail/INBOX/.imap/Logger Call/dovecot.index: Extension header update points outside header size Apr 30 09:00:12 server dovecot: imap(john): Error: Log synchronization error at seq=2,offset=524384 for /home/john/Mail/INBOX/.imap/Logger Reset/dovecot.index: Extension header update points outside header size Apr 30 09:00:12 server dovecot: imap(john): Error: Log synchronization error at seq=2,offset=500144 for /home/john/Mail/INBOX/.imap/River Murray/dovecot.index: Extension header update points outside header size Apr 30 09:00:12 server dovecot: imap(john): Error: Log synchronization error at seq=2,offset=532680 for /home/john/Mail/INBOX/.imap/SMS Emails/dovecot.index: Extension header update points outside header size Apr 30 09:00:12 server dovecot: imap(john): Error: Log synchronization error at seq=2,offset=515436 for /home/john/Mail/INBOX/.imap/Soil Moisture Alert/dovecot.index: Extension header update points outside header size Apr 30 09:00:12 server dovecot: imap(john): Error: Log synchronization error at seq=2,offset=578508 for /home/john/Mail/INBOX/.imap/Water Management Alarm/dovecot.index: Extension header update points outside header size Apr 30 09:00:12 server dovecot: imap(john): Error: Log synchronization error at seq=2,offset=648164 for /home/john/Mail/INBOX/.imap/Water Usage/dovecot.index: Extension header update points outside header size Apr 30 09:00:12 server dovecot: imap(john): Error: Log synchronization error at seq=2,offset=492876 for /home/john/Mail/INBOX/.imap/Weather Summaries/dovecot.index: Extension header update points outside header size Apr 30 09:00:12 server dovecot: imap(john): Error: Log synchronization error at seq=2,offset=495744 for /home/john/Mail/INBOX/.imap/Zerna/dovecot.index: Extension header update points outside header size Apr 30 09:00:38 server dovecot: lda(john): Error: Log synchronization error at seq=2,offset=578596 for /home/john/Mail/INBOX/.imap/Water Management Alarm/dovecot.index: Extension header update points outside header size Apr 30 09:00:38 server dovecot: lda(john): Error: Log synchronization error at seq=2,offset=578684 for /home/john/Mail/INBOX/.imap/Water Management Alarm/dovecot.index: Extension header update points outside header size Apr 30 09:00:38 server dovecot: lda(john): Error: Log synchronization error at seq=2,offset=578880 for /home/john/Mail/INBOX/.imap/Water Management Alarm/dovecot.index: Extension header update points outside header size At about the same time, I asked about fsck warnings.

[Dovecot] mdbox corruption
by Daniel L. Miller 02 May '12

02 May '12

I have isolated the corruption in a mailbox to 4 mdbox files. Two of these (smaller) files cause the force-resync to report a breakage and save the file as m.XX.broken. The other two (larger) files cause a crash. Is there a way I can fix these files and recover the mails? -- Daniel

[Dovecot] dovecot, ldap and multiple auth_bind_userdn
by Cédric Jeanneret 01 May '12

01 May '12

Hello List! I'm having some troubles for a client of mine: he has two ldap branches which may contain valid users for imap login... For now, dovecot is configured so that it uses the auth_bind: ======== uris = ldap://localhost:389/ auth_bind = yes auth_bind_userdn = uid=%u,ou=user,dc=org ldap_version = 3 base = dc=artemis user_attrs = user_global_uid = 8 user_global_gid = 8 pass_attrs = uid=user ## other options user_filter = (uid=%u) pass_filter = (uid=%u) default_pass_scheme = CRYPT ======== Unfortunately, I cannot manage to tell him "hey guy, uses those two branches": uid=%u,ou=user,dc=org and uid=%u,ou=external,dc=org Is there a special way to do that ? Is it even possible ? I cannot modify the ldap tree, so this option is out, unfortunately :(. My dovecot version: dovecot --version 1.2.15 Thanks in advance for your answers. Cheers, C.

[Dovecot] question dovecot Inheritance global acl vs userfolder acl
by Robert Schetterer 01 May '12

01 May '12

Hi Timo my tests resulted in inheritance is given if a userfolder has set some acl to its new created subfolder , which is nice if some userfolder has its acl from global acl there is no inheritance to its new created subfolders, that subfolders will always created with full owner rights i am not really sure if its a good idea to have inheritance from global acl and if its hackabel what is your idea to this ? -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

Hello, i'm using kmail2 and for Folder Settings the SETANNOATION command is needed. Is there any way to add this command to Dovecot? I already found a dovecot-metadata-plugin but there is no Package available for Debian. Thanks Dieter

I upgraded to 2.1.5, and we have the same assertion failure, on the same mailbox: Apr 27 16:02:03 imap(nu-imaptest00258(a)example.com): Panic: file mailbox-list-fs.c: line 156 (fs_list_get_path): assertion failed: (mailbox_list_is_valid_pattern(_list, name)) Apr 27 16:02:03 imap(nu-imaptest00258(a)example.com): Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0(+0x4246a) [0x7f310c28146a] -> /usr/lib64/dovecot/libdovecot.so.0(+0x424b6) +[0x7f310c2814b6] -> /usr/lib64/dovecot/libdovecot.so.0(+0x1950a) [0x7f310c25850a] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0x889b5) [0x7f310c5539b5] -> +/usr/lib64/dovecot/lib10_quota_plugin.so(+0x8a30) [0x7f3109ccea30] -> /usr/lib64/dovecot/lib10_quota_plugin.so(+0x8cdf) [0x7f3109ccecdf] -> /usr/lib64/dovecot/lib10_quota_plugin.so(+0x93c8) +[0x7f3109ccf3c8] -> /usr/lib64/dovecot/lib10_quota_plugin.so(+0x9436) [0x7f3109ccf436] -> /usr/lib64/dovecot/lib10_quota_plugin.so(quota_get_resource+0x72) [0x7f3109cca792] -> +/usr/lib64/dovecot/lib10_quota_plugin.so(quota_test_alloc+0x1bd) [0x7f3109ccaaed] -> /usr/lib64/dovecot/lib10_quota_plugin.so(+0xa870) [0x7f3109cd0870] -> +/usr/lib64/dovecot/libdovecot-storage.so.0(mailbox_save_begin+0x4d) [0x7f310c544b9d] -> dovecot/imap [nu-imaptest00258(a)example.com 127.0.0.1 APPEND]() [0x408ac4] -> dovecot/imap +[nu-imaptest00258(a)example.com 127.0.0.1 APPEND](cmd_append+0x139) [0x408d69] -> dovecot/imap [nu-imaptest00258(a)example.com 127.0.0.1 APPEND](command_exec+0x3d) [0x410aed] -> dovecot/imap +[nu-imaptest00258(a)example.com 127.0.0.1 APPEND]() [0x40fa2e] -> dovecot/imap [nu-imaptest00258(a)example.com 127.0.0.1 APPEND]() [0x40fb1a] -> dovecot/imap [nu-imaptest00258(a)example.com +127.0.0.1 APPEND](client_handle_input+0x135) [0x40fd45] -> dovecot/imap [nu-imaptest00258(a)example.com 127.0.0.1 APPEND](client_input+0x5f) [0x41066f] -> +/usr/lib64/dovecot/libdovecot.so.0(io_loop_call_io+0x36) [0x7f310c28d9d6] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run+0x9f) [0x7f310c28ea5f] -> +/usr/lib64/dovecot/libdovecot.so.0(io_loop_run+0x28) [0x7f310c28d978] -> /usr/lib64/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f310c279c73] -> dovecot/imap [nu-imaptest00258(a)example.com +127.0.0.1 APPEND](main+0x29d) [0x418b3d] -> /lib64/libc.so.6(__libc_start_main+0xfd) [0x7f310bebccdd] -> dovecot/imap [nu-imaptest00258(a)example.com 127.0.0.1 APPEND]() [0x408449] Apr 27 16:02:03 imaptest01 perdition.imap4[15893]: Closing session: 211.29.132.209:42922->211.29.132.245:143 authorisation_id=NONE authentication_id="nu-imaptest00258" received=67 sent=53 Apr 27 16:02:03 imap(nu-imaptest00258(a)example.com): Fatal: master: service(imap): child 15894 killed with signal 6 (core not dumped) Any suggestions welcome.

[Dovecot] restoring mails and directories
by oni-neko＠gmx.net 01 May '12

01 May '12

Good day! is there an easy way to restore e.g. deleted mails and/or mail directories? let me specify: I'm running dovecot 1.2.9 on a current ubuntu lts. It is set to Maildir and I backup the folder with the users maildata nightly via rsync. now, when someone deletes a mail that they still need, and I copy it back from the backup, it will not be visible to mail clients. When I change the mailfile by a letter or so, it shows. that's easy enough, if not exactly awesome ;-) But, if said person deletes a whole folder of mails, this way to make restored mails show up becomes rather unreasonable. surely there is a better way to do this? I'd be glad for any and all hints! =) best regards silvana -- Empfehlen Sie GMX DSL Ihren Freunden und Bekannten und wir belohnen Sie mit bis zu 50,- Euro! https://freundschaftswerbung.gmx.de

[Dovecot] Dovecot dsync mail replication issues
by Reuben Farrelly 01 May '12

01 May '12

Hi, I'm trying to set up some dsync based replication between two hosts on my network. The current topology is a single server running Postfix with a single dovecot installation with a Maildir per user (only 4 users including myself). No NFS, just local system users on ext4. I am only using system users, ie no virtual users. I am using dovecot deliver to deliver mails into the Maildir's. This - being a very standard Maildir installation - all works just fine. I'm running dovecot-2.1.5 (release versions) x86_64 with Gentoo on both hosts and using key based ssh to transport the data using the root login. What I would like to do is extend the design so as to replicate the Maildirs across a second machine and in the future be able to connect via IMAP into either machine to sync mail. Two way dsync would be rather cool because I could then deliver via SMTP to either system and have changes automagically propagate - but initially just simple replication would be a good start. I was hoping that dsync would allow me to do this, but I've run into quite a number of problems while getting this to work. http://dovecot.org/list/dovecot/2012-March/064243.html ...was very useful and I've based my config on that. Initially I've tried to sync up the user Maildirs, and this has more or less worked: doveadm sync -u lyn remote:root@dustbowl.reub.net This succeeds without error on the initial sync. However if I try to run the re-sync again (such as a use case of if the sync of another Maildir takes 4 hours so I want to resync up the earlier ones again) I end up with a mysteriously named INBOX folder in both the source and destination Maildirs: drwx------ 5 lyn lyn 4096 Apr 30 19:32 .INBOX_7a86a62d465a974fb92f00003b258734 It has the basic structure of a Maildir but is empty in terms of mails: drwx------ 2 lyn lyn 4096 Apr 30 19:32 cur -rw------- 1 lyn lyn 220 Apr 30 19:32 dovecot.index.log -rw------- 1 lyn lyn 51 Apr 30 19:32 dovecot-uidlist -rw------- 1 lyn lyn 0 Apr 30 19:32 maildirfolder drwx------ 2 lyn lyn 4096 Apr 30 19:32 new drwx------ 2 lyn lyn 4096 Apr 30 19:32 tmp First question: why is this random named directory being created in the origin Maildir? Shouldn't the replication be more or less read-only in the origin Maildir? Second question: If I re-attempt a doveadm sync a second time I get this error: tornado Maildir # doveadm sync -u lyn remote:root@dustbowl.reub.net dsync-local(lyn): Error: Can't rename mailbox INBOX_7a86a62d465a974fb92f00003b258734 to INBOX: Target mailbox already exists dsync-local(lyn): Error: Can't rename mailbox INBOX to INBOX_eb15f30ea563be4b703200002bd68bb1: Renaming INBOX isn't supported. tornado Maildir # It's not clear if the second attempt has failed or succeeded, and it's a bit odd that it errors out on a directory that the dovecot sync process itself has created. Third question: Upon starting Dovecot lots of ugliness is logged in the mail log: Apr 30 19:44:59 tornado dovecot: master: Dovecot v2.1.5 starting up (core dumps disabled) Apr 30 19:44:59 tornado dovecot: doveadm(mozsync): Error: user mozsync: Initialization failed: Namespace '': mkdir(/var/www/xxx/server-full/Maildir) failed: Permission denied (euid=1016(mozsync) egid=1016(<unknown>) missing +w perm: /var/www/xxx/server-full, dir owned by 0:0 mode=0755) Apr 30 19:44:59 tornado dovecot: doveadm(mozsync): Error: sync: User init failed Apr 30 19:44:59 tornado dovecot: doveadm(mozsync): Warning: I/O leak: 0x414190 (line 102, fd 16) Apr 30 19:44:59 tornado dovecot: dsync-local(cisco): Error: remote: doveadm(cisco): Fatal: User doesn't exist Apr 30 19:44:59 tornado dovecot: dsync-local(cisco): Error: read() from worker server failed: EOF Users mozsync and cisco are not valid mail users and it's not appropriate that Dovecot tries to create a Maildir for either of them. The users are system unprivileged users only, and do not ever send or receive mail. And - I/O leak? ;) Also, user cisco is local to one box only, and does not exist (nor does it need to) on the remote host. So any complaints about this user are invalid and dovecot needs to ignore replication for this user anyway. Fourth question, upon starting dovecot again, mail.log then spews several hundred of these messages: Apr 30 19:45:06 tornado dovecot: dsync-local(reuben): Error: msg-get failed: box=Trash uid=114863 guid=1335382569.M98089P29952.tornado,S=6479,W=6625 Before aborting entirely with: Apr 30 19:45:09 tornado dovecot: imap: Server shutting down. in=328 out=2042 It seems to me that a a few of those problems logged could be solved by being able to specify which system users to synchronise, rather than Dovecot making a blind assumption that all users actually have valid Maildirs that need to be created, and all need to be sync'd between two hosts. Subsequent delivery based sync'ing fails silently (pending more investigation) but I'd like to try and fix the above listed problems first before worrying about the later stages of the sync not working. Has anyone else run into these problems or found better ways of making this type of setup all work? Thanks, Reuben

[Dovecot] Sieve doesn't find user scripts
by Jochen Spieker 30 Apr '12

30 Apr '12

Hi, I want to use Sieve filtering with my Dovecot 1.2 installation on Debian squeeze. I have a virtual domain setup using Portgresql. ManageSieve works fine so far, I can edit and activate/deactive scripts (using Thunderbird + Plugin) and they show up in the filesystem where I expect them to be, see below. The problem is that LDA doesn't find the script.

[Dovecot] Refiltering mails without loosing flags
by Dieter Knopf 30 Apr '12

30 Apr '12

Hello, is there a way to refilter all mails in a folder without loosing all flags and moving all messages in a different folder? I have >10k mails in my Inbox and need to create new filterrules from time to time. But there is no way to refilter my inbox without moving. Atm i need to move all mails in a folder like "refilter" and then run getmail/... to refilter the mails. It would be really nice to refilter a existing folder and just move mails with hits in the filter list. Thanks Dieter
