[Dovecot] install sieve without any dovecot sources
by Δημήτριος Καραπιπέ ρης 17 Aug '09

17 Aug '09

Hi all I have dovecot 1.1.16 (dovecot-1.1.16-0_94.el5 x86-64) installed on a Red Hat Enterprise v.5. I am already using Dovecot's deliver for virtual users local delivery and need to install the cmusieve plugin for the filtering capabilities. I don't have any sources, since I installed Dovecot from a binary package. Is there any way to install the cmusieve plugin? Thanks in advance Dimitrios Karapiperis

[Dovecot] Crash in v1.2.3: istream.c: assertion failed on line 99
by Phillip Macey 17 Aug '09

17 Aug '09

Hi, I have a couple of people bumping into an issue with their imap process crashing - from the users perspective, their mail client (thunderbird) just stops recieving new mail. It still seems to be possible for them to read their mail using squirell mail. When it crashes, it leaves behind a log message like this on the server: Aug 12 15:52:25 fury dovecot: imap-login: Login: user=<zhi>, method=PLAIN, rip=10.8.5.15, lip=10.10.0.26 Aug 12 15:52:25 fury dovecot: IMAP(zhi): Panic: file istream.c: line 99 (i_stream_read): assertion failed: ((size_t)ret+old_size == _stream->pos - _stream->skip) Aug 12 15:52:25 fury dovecot: IMAP(zhi): Raw backtrace: imap [0x49ddc0] -> imap [0x49de23] -> imap [0x49d4a6] -> imap [0x4a252e] -> imap [0x4a4691] -> imap(i_stream_read+0x48) [0x4a23f8] -> imap(i_stream_read_data+0x28) [0x4a2558] -> imap [0x4ab22e] -> imap(o_stream_send_istream+0x2e) [0x4aa63e] -> imap(maildir_save_continue+0x32) [0x443d12] -> imap(mail_storage_copy+0x6a) [0x462a1a] -> imap(maildir_copy+0x5e) [0x441d2e] -> imap(cmd_copy+0x1fe) [0x41a94e] -> imap(cmd_uid+0x78) [0x41f8d8] -> imap [0x42053c] -> imap [0x4205f2] -> imap(client_handle_input+0x3f) [0x42072f] -> imap(client_input+0x5f) [0x42127f] -> imap(io_loop_handler_run+0xf8) [0x4a5b08] -> imap(io_loop_run+0x1d) [0x4a4c1d] -> imap(main+0x620) [0x428b80] -> /lib64/libc.so.6(__libc_start_main+0xf4) [0x353e41d974] -> imap [0x4198f9] Aug 12 15:52:25 fury dovecot: dovecot: child 14759 (imap) killed with signal 6 (core dumps disabled) I was able to fairly reliably trigger the same behaviour myself by attempting to move a bunch (thousands) of emails in my account using thunderbird - I dont know exactly what it is that triggers the crash though.

[Dovecot] How to disable system users from receiving mail?
by Paul H Park 17 Aug '09

17 Aug '09

I know that login can be disable for system users and groups, but how do I refuse email for system groups? It's a bit of a security/maintenance irritation - I don't want to check for such spam mail, since that is possible. Thanks for any help!! Answer preferably given, so that I can configure it through webmin please.

[Dovecot] can't deliver with Kerberos username
by Nikolay Shopik 16 Aug '09

16 Aug '09

I've been trying to use Kerberos and PLAIN text file for authentication. I've setup deliver in postfix master.cf and make sure correct username are expanded but deliver is always told me "user unknown". I can logon into mailbox using Kerberos w/o problems and can send emails. Looks like Dovecot lookup up passwd files and not finding users which are in Kerberos realm. # 1.0.15: /etc/dovecot/dovecot.conf log_path: /var/log/dovecot.log protocols: imap ssl_cert_file: /etc/postfix/new_chained.crt ssl_key_file: /etc/postfix/mail.pem login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_greeting_capability: yes mail_location: maildir:/var/mail/store/%u dotlock_use_excl: yes maildir_copy_with_hardlinks: yes auth default: mechanisms: PLAIN CRAM-MD5 GSSAPI passdb: driver: passwd-file args: /etc/dovecot/passwd userdb: driver: static args: uid=vmail gid=vmail home=/var/mail/store/%u socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 438 user: root group: root plugin: sieve: /var/mail/store/%u/sieve

[Dovecot] Listing shared mailboxes with a domainpart
by Mathias Tausig 16 Aug '09

16 Aug '09

Hy! I am currently configuring a new mailserver using postfix and dovecot 1.2.1. The filesystem strucutre in my spool directory is user1/ user2/ domain/info/ domain/office/ user1 and unser2 are ordinary users mailboxes, the latter two contain the virtual mailboxes for info@domain and office@domain as created by postfix. I want these virtual mailboxes (all of them are in maildir format) to be shared to certain real users. I configured a shared namespace: namespace shared { separator = / prefix = shared/%%d/%%n/ location = maildir:/var/spool/vmaildir/%%d/%%n/ #I tried ths as well # prefix = shared/%%u/ # location = maildir:/var/spool/vmaildir/%%u/ hidden = no subscriptions = no list = yes inbox = no } Then I configured a dictionary to list the folders, as described in the wiki: plugin { acl_shared_dict = proxy::acl } dict { acl = mysql:/etc/dovecot/dovecot-dict-sql.conf } where /etc/dovecot/dovecot-dict-sql.conf holds map { pattern = shared/shared-boxes/user/$to/$from table = virtual_user_shares value_field = dummy fields { from_user = $from to_user = $to } } The database table consists of +-------------+------------+-------+ | from_user | to_user | dummy | +-------------+------------+-------+ | info@domain | user1 | 1 | +-------------+------------+-------+ But when I login as user1 I can neither see nor subscribe to the info@domain mailbox. In the "flat" case (sharing the user2 mailbox to user1), this setup works. I am pretty clueless how to go on. cheers Mathias

[Dovecot] Released Sieve v0.1.10 for Dovecot v1.2.2
by Stephan Bosch 15 Aug '09

15 Aug '09

Hello Dovecot users, In the last week two nasty bugs were found in the new Sieve implementation. Primarily, the include extension did not work when a compiled binary was loaded from disk. This is something that is still not tested by the test suite, giving this bug the opportunity to slip through. Also, the value matching implementation would sometimes cause a assertion failure. Other than that, various small bugs were fixed. On the more positive side, I have implemented support for the new mailbox extension (RFC 5490), which provides the means to test whether a mailbox exists. Also, it adds the :create argument to the fileinto command, which makes sure that the target folder is created before saving is attempted. Of course, this is only useful when deliver is used with the -n option. There wasn't a great need for this extension, but I could use it in the test suite and it was almost trivial to implement. In other news, I have further developed the sieve-filter command line tool. It is getting closer to a usable state, being able to filter a large number of messages in an existing mailbox, but its use is currently still very much discouraged as it tends to be very good at eating mailboxes when the user is less attentive. It needs more command line configuration options, a simulation mode to perform a dry run, and a man page that describes its use and its dangers. Changelog for Sieve v0.1.10: * Changed action execution of fileinto and keep. These changes depend on API additions in Dovecot, making this release depend on Dovecot v1.2.2 or newer. * Further developed the sieve-filter command line tool. This required a few changes to the action execution of the Sieve engine. The tool was successfully tested on folders with a few 100k spam messages. However, the commandline options are still incomplete, a man page is missing and it needs much more testing before I can recommend anyone to use this tool. + Added support for the mailbox extension. This allows checking whether a mailbox exists using the mailboxexists command and it adds the :create argument to the fileinto command to create the mailbox when it is missing. The :create feature is useless unless the Deliver LDA is run with the -n option. + Improved the testsuite with tests for message delivery. Messages stored using keep and fileinto can be fed back into the Sieve engine for verification. This includes testing of applied IMAP flags. + Updated the man pages with the new method of specifying the supported extensions using + and - (for the -x parameter of the sieve tools) + Further developed the deprecated notify extension. A dummy for the denotify command exists, meaning that its use does not cause an error anymore. - Fixed a bug in the derivation of the binary path from the script path. A bare filename would yield a path relative to root. - Fixed a bug in the value matching code. The context data now uses a proper pool in stead of the data stack. Bug reported by Jan Sechser. - Fixed assertion fail in the include extension caused by missing initialization upon binary load. This bug surfaces only for stored binaries. Bug reported by Tom Hendrikx. - Fixed include error message for failed :global include. It mentioned the wrong config parameter. - Fixed broken wiki reference in an error message of the plugin about the 'sieve' setting. - Fixed behavior of fileinto when delivering into a namespace prefix. Previous fix used the wrong storage. The release is available as follows: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.10.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.10.tar.gz.sig Have fun testing the new releases and don't hesitate to notify me when there are problems. Please include your configuration, the involved Sieve scripts and an example message in any bug or problem report when possible, so that I can easily reproduce the issue. Regards, -- Stephan Bosch stephan(a)rename-it.nl

Re: [Dovecot] Redirecting mail gives 'mail forwarding loop' to the sender - calling for sieve help
by Andrés Yacopino 15 Aug '09

15 Aug '09

Yes, the configuration seems odd or interesting as you said. The idea behind this is: - Before scripts will be use for filtering spam, when they have SPAM header. Not problem at it. - User scripts will be used for vacation messages. These are created with Squirrelmail and avelsize plugin (user interaction) - After scripts will be used for doing redirections, such as forwarding mail to a blackberry account(not problem at it) or forwarding to another user account (in the same domain, the problem is here). The reason not to put the redirections or forwarding in users scripts is to avoid users deleting redirections and have in one file all the redirections. I also try to use redirections from avelsieve plugin (0.9.9.9) and it works the forwarding but it didn't work the keep command, the mail is forwarded but the user doesn't have a copy of it. I will investigate your advice for envelope or try to use user's scripts. I didn't know about original headers, if this in RFC sieve documents? Thanks Timo and thanks Stephan for the tips.

[Dovecot] Very long establishment time for secondary connections
by Jeff Mitchell 14 Aug '09

14 Aug '09

Hello, I'm currently on Dovecot 1.1.17 and I have a user that runs into a problem quite a lot. She's using Thunderbird on a Mac. When she sends mail, Thunderbird is set up to save sent mail to her Sent folder. Often (usually when she has not sent another mail for a long while) when she sends mail, Thunderbird sits there saying "Copying message to Sent folder" for about thirty seconds. My best guess, after looking at dovecot messages in syslog related to her login, is that Thunderbird is using a secondary imap process to do this copying and this connection times out due to inactivity, so that when she sends mail it has to reestablish itself. For some reason this reestablishment seems to take a very long time, even though her initial login/connection when she opens Thunderbird is very fast. I looked for a way to increase the inactivity time in dovecot.conf but didn't see one. I don't know of any other user that has this problem, which makes me suspicious of her client rather than Dovecot. Pretty much everyone is using Thunderbird, although she's the only one using it on a Mac. Is it possible/likely that it takes so long because for some reason Thunderbird on a Mac doesn't notice that the second connection has died and is taking a long time trying to use the first invalid connection before reestablishment? Or is it likely that this is a Dovecot problem and I simply haven't figured out what's going on, yet? All help very much appreciated. Thanks, Jeff

[Dovecot] Upgrade question from 1.1 to 1.2
by Wouter van der Schagt 14 Aug '09

14 Aug '09

Good afternoon, I am considering to upgrade from Dovecot 1.1.18 to 1.2.x and was reading your Wiki regarding any changes and found: "If you were using e.g. mail_location = maildir:/var/mail/%h, just change it to mail_location = maildir:%h and add /var/mail/ prefix to home dirs." I am currently using: "mail_location = maildir:~/Maildir" in combination with vpopmail. Does this need to be changed? or is ~/Maildir considered an absolute directory? Is there anything else I should be aware of ? Sincerely, - Wouter van der Schagt

[Dovecot] Dovecot Proxy
by Michel Bulgado 14 Aug '09

14 Aug '09

Hello I have installed Dovecot as a POP3 server, IMAP on my internal network, the authentication against Windows Active Directory. I would like to know how to setup a second server dovecot as my proxy server for external users outside the network, in another segment of different IP addresses, or at least define which mailboxes will be stored on another server to be accessible to both servers. I have reviewed the document on the wiki site, but I said that is only possible with mysql authentication, but as I said the road where the messages are stored, it is possible for NFS? Thanks Michel

[Dovecot] QUOTA not appearing in CAPA
by Tim Traver 14 Aug '09

14 Aug '09

Hi, ok, I've compiled it a few times, and made sure all of my settings are correct, but the QUOTA is not appearing in the opening CAPA that comes with the greeting. I have it configured in the dovecot.conf like so: protocol imap { mail_plugins = quota imap_quota } and I can see when turning debugging on that the following is spit out when starting : Starting DovecotILoading modules from directory: /usr/local/lib/dovecot/imap IModule loaded: /usr/local/lib/dovecot/imap/lib10_quota_plugin.so IModule loaded: /usr/local/lib/dovecot/imap/lib11_imap_quota_plugin.so IEffective uid=65534, gid=65534, home=/tmp IQuota root: name= backend=maildir args= IEffective uid=65534, gid=65534, home=/tmp and then I see the following in the dovecot logs : Aug 10 17:35:10 IMAP(xxxxx(a)simplenet.com): Info: Module loaded: /usr/local/lib/dovecot/imap/lib10_quota_plugin.so Aug 10 17:35:10 IMAP(xxxxx(a)simplenet.com): Info: Module loaded: /usr/local/lib/dovecot/imap/lib11_imap_quota_plugin.so when I log into the IMAP port, I get the following greeting : * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN AUTH=LOGIN] Dovecot ready. So it seems there is no QUOTA support for the IMAP server to query for the quota file... can someone help me as to a direction to go here??? The reason I need it is because I believe the web client relies on the QUOTA being in the CAPA in order to show it... Thanks, Tim.

[Dovecot] More effective mailbox fetching over high RTT link
by Andrzej Adam Filip 13 Aug '09

13 Aug '09

Could you offer some suggestion how to fetch mailbox content over high RTT link (with negligible packet loss)? Currently I use IMAP+IDLE *but* it fails to use full available bandwidth due to high RTT and "send command wait for response" nature of POP3 and IMAP4 protocols. -- [pl>en: Andrew] Andrzej Adam Filip : anfi(a)onet.eu Learning without thought is labor lost; thought without learning is perilous. -- Confucius

[Dovecot] sieve: variable extension?
by Lev Serebryakov 13 Aug '09

13 Aug '09

Hello, Dovecot. Does dovecot sieve supports variable extension (rfc5229)? It is very useful for users with large amount of mailing lists, as it allows to write only one rule for all lists (filtering by List-Id). If it is not supported, is here any plans to support it? I can try to implement it, but I don't want to duplicate work, if somebody has this extension in pipeline. -- // Black Lion AKA Lev Serebryakov <lev(a)serebryakov.spb.ru>

[Dovecot] Tilde expansion in ManageSieve for dovecot-1.1.
by Stephen O'Dor 13 Aug '09

13 Aug '09

Greetings all, I'll skip the details of the setup, except to say that it has a non-standard (and non-templateable) home directory path for virtual users. Ran into the following problem when a debian (possibly from backports) packaged dovecot-1.1.2 was upgraded to a dovecot-1.1.13-2~bpo50+1 (definately from backports): sieve-storage: root directory specified by mail data does not exist: ~/Maildir After some analysis, it would appear that ManageSieve (looks like 0.10.4 is included in the debian backports) doesn't do the tilde expansion before doing a stat test to see if the ~/Maildir exists. Here's a quick diff of the change I made to make it work: sodor@madawg:~/tmp/deb-dove/dovecot-1.1-managesieve-0.10.4/src/lib-sievestorage$ diff sieve-storage.c ../../../sieve-storage.c 73c73 < const char *root_dir, *dir, *p, *d; --- > const char *root_dir, *dir, *p, *d, *home; 127a128,133 > /* expand tilde in root so that the stat below works */ > home = getenv("HOME"); > if (home != NULL && *home != '\0') { > root_dir = home_expand_tilde( root_dir, home ); > } > I'm not sure if this was the best way to fix this (or if this is even a bug, I might just have a crazy setup). Thanks, -Steve

[Dovecot] Dovecot proxy server
by michel＠casa.co.cu 13 Aug '09

13 Aug '09

Hello I have installed Dovecot as a POP3 server, IMAP on my internal network, the authentication against Windows Active Directory. I would like to know how to setup a second server dovecot as my proxy server for external users outside the network, in another segment of different IP addresses, or at least define which mailboxes will be stored on another server to be accessible to both servers. I have reviewed the document on the wiki site, but I said that is only possible with mysql authentication, but as I said the road where the messages are stored, it is possible for NFS?

[Dovecot] user_global_* ldap deliver
by Noel Leistad 12 Aug '09

12 Aug '09

Searched archive, but failed to find... :-( "deliver" does not honor user_global_* from dovecot-ldap.conf or userdb static{} also it looks like delivery attempts being made to %n/Maildir/cur ?? one other curious thing, use of ${recipient} in master.cf|deliver command causes the "passdb ldap" lookups to be completely ignored? only checks passdb and ignores userdb compleletely? IF I put noel(at)metc(dot)net into passwd.dovecot using passdb flatfile, auth and delivery seem to work. Thanks for any direction. I lament I couldn't get farther on my own.

[Dovecot] Dovecot Versions and Debian
by Mario Antonio 12 Aug '09

12 Aug '09

If you want to run Dovecot on Debian Lenny for a Production System (with Fast Upgrade System for Security Patches), What would you recommend? Stick to the current port with Dovecot Version 1.0.15 (1:1.0.15-2.3) Use Backports Version 1.1.13 (1:1.1.13-2~bpo50+1) or Use any of the packages from: ---------------------------------------------------------------------------------------------------------------------- Dovecot v1.1 for Debian Testing (binary and source): deb http://xi.rename-it.nl/debian/ testing-auto/dovecot-1.1 main deb-src http://xi.rename-it.nl/debian/ testing-auto/dovecot-1.1 main Dovecot v1.2 for Debian Testing (binary and source): deb http://xi.rename-it.nl/debian/ testing-auto/dovecot-1.2 main deb-src http://xi.rename-it.nl/debian/ testing-auto/dovecot-1.2 main ---------------------------------------------------------------------------------------------------------------------- Do you find any compelling reason for not using version 1.0.15 ? (Besides of ACL limitations ...) Regards, Mario Antonio

[Dovecot] sieve/managesieve and spam filtering
by Charles Sprickman 11 Aug '09

11 Aug '09

Hello all, I've got a test environment setup in preparation for a move from qmail/vpopmail/courier to postfix/padmin/dovecot. I have a number of questions that seem to span multiple pieces of software, and this is one of them... Our policy with spam filtering is that a user should be able to turn it off (ie: not put tagged spam into a spam folder, but deliver to their inbox) if they want to. Currently qmailadmin and a custom squirrelmail plugin give people the option to do this by dumping a .qmail file in their directory that calls a common maildrop script that will deliver spam to the spam folder. It looks like I can emulate this with sieve and something that can speak to Dovecot's managesieve server. Where I'm stuck is that if I want users to be able to do other custom filtering using sieve, how do I go about making sure that my common spam delivery rule does not get clobbered? This really has me a bit stumped. I see there's a global sieverc that can be included, but I need something along the lines of a per-user include that brings in the spam filtering rule that will "stick" until the user explicitly deletes it. Any ideas? Thanks, Charles ___ Charles Sprickman NetEng/SysAdmin Bway.net - New York's Best Internet - www.bway.net spork(a)bway.net - 212.655.9344

[Dovecot] Index cache file problems in Dovecot 1.2.0
by Chris Wakelin 11 Aug '09

11 Aug '09

I've been seeing lots of index cache file errors (using mbox on Solaris 8 sparc 64-bit, but with 32-bit Dovecot) since I switched my account to Dovecot 1.2.0 (we're still on 1.0.15 mostly, but I'm hoping to upgrade to 1.1.17+ this summer, or 1.2.x if it's stable enough). e.g. Error: Corrupted index cache file <path>/.imap/INBOX/dovecot.index.cache: field index too large (47 >= 25) I've tried renaming/removing the .imap/INBOX directory, but the "Corrupted index cache file" errors return within a day or so. This morning, Thunderbird got itself in a mess retrying something that caused multiple core dumps: > Jul 14 08:52:53 dovecot: Error: child 17694 (imap) killed with signal 10 (core dumped) > Jul 14 08:52:54 dovecot: Error: child 17697 (imap) killed with signal 10 (core dumped) > Jul 14 08:52:55 dovecot: Error: child 17700 (imap) killed with signal 10 (core dumped) Here's a backtrace > #0 mail_cache_get_record (cache=0x124e28, offset=289, rec_r=0xffbeeb6c) > at mail-cache-lookup.c:30 > 30 if (rec->size < sizeof(*rec)) { > (gdb) bt > #0 mail_cache_get_record (cache=0x124e28, offset=289, rec_r=0xffbeeb6c) > at mail-cache-lookup.c:30 > #1 0x84e2c in mail_cache_lookup_iter_next_record (ctx=0xffbeeb60) > at mail-cache-lookup.c:186 > #2 0x84f14 in mail_cache_lookup_iter_next (ctx=0xffbeeb60, field_r=0xffbeeb50) > at mail-cache-lookup.c:219 > #3 0x85650 in mail_cache_lookup_headers_real (view=0x128510, dest=0x129728, > seq=11416, field_idxs=0xffbeec74, fields_count=2) > at mail-cache-lookup.c:500 > #4 0x85848 in mail_cache_lookup_headers (view=0x128510, dest=0x129728, > seq=11416, field_idxs=0xffbeec74, fields_count=2) > at mail-cache-lookup.c:555 > #5 0x6ba94 in index_mail_get_raw_headers (mail=0x128f20, > field=0xff142ee8 "Message-ID", value_r=0xffbeecfc) > at index-mail-headers.c:614 > #6 0x6c084 in index_mail_get_first_header (_mail=0x128f20, > field=0xff142ee8 "Message-ID", decode_to_utf8=false, value_r=0xffbeede4) > at index-mail-headers.c:771 > #7 0x7893c in mail_get_first_header (mail=0x128f20, > field=0xff142ee8 "Message-ID", value_r=0xffbeede4) at mail.c:118 > #8 0xff1419a0 in mail_log_add_hdr (mail=0x128f20, str=0x10edc8, > name=0xff142d68 "msgid", header=0xff142ee8 "Message-ID") > at mail-log-plugin.c:277 > #9 0xff141c5c in mail_log_action (dest_trans=0x128f20, mail=0x128f20, > event=MAIL_LOG_EVENT_DELETE, data=0x0) at mail-log-plugin.c:318 > #10 0xff141e5c in mail_log_mail_update_flags (_mail=0x128f20, > modify_type=MODIFY_ADD, flags=12) at mail-log-plugin.c:376 > #11 0x78af8 in mail_update_flags (mail=0x128f20, modify_type=MODIFY_ADD, > flags=12) at mail.c:184 > #12 0x2ab3c in cmd_store (cmd=0x11bec8) at cmd-store.c:192 > #13 0x2b5f8 in cmd_uid (cmd=0x11bec8) at cmd-uid.c:27 > #14 0x2ccc4 in client_command_input (cmd=0x11bec8) at client.c:611 > #15 0x2cb68 in client_command_input (cmd=0x11bec8) at client.c:660 > #16 0x2cd4c in client_handle_next_command (client=0x11bc40, > remove_io_r=0xffbef23f) at client.c:701 > #17 0x2ce40 in client_handle_input (client=0x11bc40) at client.c:713 > #18 0x2cf78 in client_input (client=0x11bc40) at client.c:752 > #19 0xc6c04 in io_loop_handler_run (ioloop=0x1186d8) at ioloop-poll.c:203 > #20 0xc63f4 in io_loop_run (ioloop=0x1186d8) at ioloop.c:338 > #21 0x369f4 in main (argc=1107968, argv=0xffbef484, envp=0xffbef494) > at main.c:323 I didn't have these problems with 1.1.x.

[Dovecot] Problems with Dovecot 1.2.3 + IMAP (SSL) + iPhone OS 3.0
by Sascha Scandella 11 Aug '09

11 Aug '09

Hello Has anyone else problems with Dovecot 1.2.3? For clients such as Thunderbird, Outlook 2007 everything works perfect. When I use an iPhone the child process is killed: Aug 11 08:08:44 imap-login: Info: Login: user=<username>, method=PLAIN,rip=1.2.3.4, lip=4.3.2.1, TLS Aug 11 08:08:44 dovecot: Error: child 5382 (imap) killed with signal 11 (core dumps disabled) Currently I have downgraded again to the working 1.2. I wonder if this problem is known or anyone is looking for it.

[Dovecot] RFC: Storing indexes in a (remote) database to increase dovecot scalability
by Mark Zealey 10 Aug '09

10 Aug '09

Hi all, This is just an idea I had over the weekend; I was wondering if instead of storing the indexes/caches on disk, it would be possible to have an option to store them in a remote database (eg mysql). There are several issues that we currently have with scaling dovecot, and I think that if it could store indexes in an external database we could alleviate most of these issues. In no particular order: 1) One major issue we have with dovecot is the number of iops it requires to keep its files in sync on our big disk arrays. If this were a mysql database, we'd have better ways of keeping these in sync, for example switching the speed at which it flushes the updates to disk, growth using partitioning/sharding, read-only slave instances etc, specific ssd storage for indexes/caches. I know that we could create a separate ssd disk array and export that over nfs too, but see issue (2) below. If indexes were stored in a mysql database we could choose to have a different reliability for the indexes (ie if the database server crashes we have 1 second of index changes lost, whereas for the email itself we can ensure it is always kept in sync on our other disk arrays). 2) nfs locking issues. No matter how hard we try, we always find there are some issues with concurrency over nfs. It really doesn't seem designed to handle these issues very well. I've not tried with nfsv4 and I believe there are some improvements there, but at the same time nfs wasn't really designed to store databases and have heavy concurrency. A proper database server (eg mysql, postgres) on the other hand thrives in this type of environment, especially when coupled with a transactional storage backend such as innodb which includes support for deadlock handling etc. 3) As we store all of our mail systems over nfs, effectively each export is a single-threaded connection to the server. No matter how fast the central nfs server you can realistically not go above 10k nfs ops/sec on the fastest of local networks due to latency issues. With mysql you could have multiple parallel connections to the central database store (1 per process?) which would mean more nfs ops available for actually serving the files. 4) Caching. Much more tuneable on a database server than in a filesystem. Eg in mysql there are loads of options to tune the various innodb/query/key caches, on nfs there are very few even on advanced netapps etc I know some of you store all your indexes on a single server locally & then store the emails on a remote central filestore. Whilst this is a good idea, it doesn't scale very well in that if the one server fails then everything has to be reindexed as clients login which causes incredible load as dovecot has to re-read most of the messages (in pop3 mode at least) in order to work out size counts etc. In my experience this reindexing would take out our email system for the best part of a day. I'm sure we could set something up with drbd mirroring or a central san array with ssd's for the index data, but this intrinsically does not scale with as much ease as a replicating database cluster could. There are also failover issues which can be very easily solved with a database system (eg mysql with an active/passive dual-master setup). Also, I know that most of these points refer to nfs; and I know that there are alternative methods (eg san + gfs or some other scalable filesystem) however most of these are relatively new technologies whereas nfs is pretty much the standard for remote file storage; certainly I'd consider it a lot more reliable when compared to the likes of gfs or lustre. Your typical large scale mail setup would be over nfs and this is the sort of environment that I've run into these scaling issues in. I've heard that gfs also doesn't work very well with 'hot spots' which indexes tend to be, although I've no first hand experience of this. So, although this post only really mentions nfs & mysql (the two technologies that I'm most familiar with) I think this is a much more general problem so I'm not advocating the use of either technology apart from them being most people's first choices for ease of use. What I'm really proposing is a way to separate the two different types of data that dovecot uses. Indexes&caches contain small frequent transactions; and whilst these are relatively important, dropping the past few seconds of these transactions doesn't seriously matter. On the other hand emails are larger, infrequently changed & it's important they are kept fully in sync - if we accept a message it should be guaranteed that we don't loose it. At the end of the day it seems to me that a filesystem is the ideal place to store emails, whereas a database server would be the ideal place to store indexes/caches. Obviously for speed of setup, simply storing everything on a filesystem is easy so I'm not suggesting that we abandon this route, but for truly large infrastructures I think being able to use a database system would have significant advantages in each of these four areas. Any thoughts?

Hi, I´m using dovecot at our storages, accounts is distributed among many storages (not entire domain), all of them with compression (when message > 30Kb), nightly crontab script. Even though compression and many storages, we always have problems with disk space and need to migrate accounts. Have you ever implemented any archive solution working with dovecot ?

[Dovecot] Mail not begin proccessed
by Andre Labuschagne 10 Aug '09

10 Aug '09

Good day all, [Dovecot version 1.2.1] I've set up postfix and dovecot on Centos. I have a problem with the mail, it is begin received but not "processed" by dovecot. I've looked in the maillog file and found two problems; the first is that private/dovecot directory (I think it should be a directory) did not exist and the second problem is "mail transport unavailable". I've create a directory called /var/spool/postfix/private/dovecot but I get the following error in the log file: Connection refused (Is this an ownership issue? I've made the owner postfix) As for the second problem, I've spend the most of the past 3 days googling the error and found very little "useful" information. Do I need to supply more info? Best regards, Andre

[Dovecot] Released Sieve v0.1.11 and ManageSieve v0.11.8 for Dovecot v1.2.3
by Stephan Bosch 10 Aug '09

10 Aug '09

Hello Dovecot users, Apart from unfinished development of the date extension, this is a set of bug-fix releases. A few portability issues were found, a few stupidities were fixed and the ManageSieve proxy now also works with TLS. Most notably, the include extension had an issue regarding the expansion of $HOME in the personal include path. I've built a project site at: http://pigeonhole.dovecot.org Changelog Sieve v0.1.11: + Built skeleton implementation for the date extension (RFC5260). It compiles, but it does not do anything useful yet. Therefore, it is not part of the default compilation. - Fixed ARM portability issues caused by char type not being signed on that platform. Reading optional operands from a binary would fail for action side effects. Also, an accidental mixup of an int return type with bool caused the interpreter to continue on ARM even though an error occured. - Removed direct stdint.h includes to prevent portability issues. - Fixed segfault bug in the handling of script open failures. - Include: improved user error messages and system log messages. - Fixed copy-paste mixup between sieve_after and sieve_before settings in the LDA Sieve plugin. If only a sieve_after script was active, nothing would have been executed. Patch by Mike Abbott. - Include: fixed a bug in HOME substitution in the sieve_dir path. Surfaced in ManageSieve. Changelog ManageSieve v0.11.8: - Fixed TLS support for proxying ManageSieve. The protocol state machine was incorrect. Also added a check that disables ssl when 'starttls' is not enabled for the user. This produces a proper warning in the log file. There is no such thing as a managesieveS protocol which has SSL from the start. The releases are available as follows: Sieve: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.11.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.11.tar.gz.sig ManageSieve (package + patch): http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.8.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.8.tar.gz.s… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.3-managesieve-0.11.8.diff.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.3-managesieve-0.11.8.diff.g… Have fun testing the new releases and don't hesitate to notify me when there are problems.

[Dovecot] virtual plugin and ACL
by Nikita Koshikov 10 Aug '09

10 Aug '09

Hello list, We are using virtual plugin for to provide users two additional folders: Company/all - it contains all messages in user's mailbox Company/favorites - here is flagged messages. Here is namespace part of config file: namespace private { prefix = Company/ separator = / location = virtual:/var/mail/virtual:INDEX=MEMORY:LAYOUT=maildir++ subscriptions = no } Everything works fine, but problem arises when someone rename or delete virtual mailbox.

[Dovecot] how secure is Dovecot when exposed to the Internet?
by Florin Andrei 10 Aug '09

10 Aug '09

$ dovecot -n # 1.1.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.28-11-server x86_64 Ubuntu 9.04 protocols: imap imaps managesieve I need to make an IMAP (actually imaps) server available over the Internet. Unfortunately, VPN is not available (not all clients support VPN), so I will have to expose the imaps port to the Internet. My question is: how reliable is Dovecot in such a setup? I am not talking about encryption (protecting the traffic between server and client). I am talking about having the daemon exposed to anything coming in from the Internet, buffer overflows and stuff like that. What's the security history of this software in situations like this? -- Florin Andrei http://florin.myip.org/

[Dovecot] Wiki entry for expire plugin, PostgreSQL trigger needs update
by Stefan Förster 09 Aug '09

09 Aug '09

The wiki entry at http://wiki.dovecot.org/Plugins/Expire needs an update for Dovecot 1.2 and PostgreSQL: -- v1.2+: CREATE OR REPLACE FUNCTION merge_expires() RETURNS TRIGGER AS $$ BEGIN IF exists(SELECT 1 FROM expires WHERE username = NEW.username AND mailbox = NEW.mailbox) THEN UPDATE expires SET expire_stamp = NEW.expire_stamp WHERE username = NEW.username AND mailbox = NEW.mailbox; RETURN NULL; ELSE RETURN NEW; END IF; END; $$ LANGUAGE plpgsql; CREATE TRIGGER mergeexpires BEFORE INSERT ON expires FOR EACH ROW EXECUTE PROCEDURE merge_expires(); At least that's what I think after looking at the code: iter = dict_iterate_init(dict, DICT_EXPIRE_PREFIX, DICT_ITERATE_FLAG_RECURSE | DICT_ITERATE_FLAG_SORT_BY_VALUE); /* We'll get the oldest values (timestamps) first */ while (dict_iterate(iter, &key, &value) > 0) { /* key = DICT_EXPIRE_PREFIX<user>/<mailbox> */ userp = key + strlen(DICT_EXPIRE_PREFIX); [...] T_BEGIN { username = t_strdup_until(userp, p); If this code does somehow iterate usernames which are not present in the dict, I apologize.

[Dovecot] User Auth
by Richard Harwood 09 Aug '09

09 Aug '09

Hello all, I am new to the mailing list and I'm in the process of setting up a LAMP + mail server. I have configured my MTA (Postfix) to deliver messages to: /var/spool/mail/vhosts/domain.tld/name I have configured Dovecot as follows: -- # 1.2.2: /usr/local/etc/dovecot.conf protocols: imap imaps pop3 ssl: no disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login mail_privileged_group: mail mail_location: mbox:/var/spool/mail/vhosts/%d:INBOX=/var/spool/mail/vhosts/%d/%n mail_debug: yes mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 lda: postmaster_address: postmaster(a)example.com auth default: debug: yes passdb: driver: passwd-file args: /etc/passwd.dovecot userdb: driver: passwd -- Password excepted, my passwd.dovecot file containing a single virtual user looks like: richard:{plain}password:504:505::/home/vmail The uid/gid is the same as used by Postfix (a dedicated vmail user/group). That user/group owns the mbox I am trying to manipulate in this example. When I attempt to login via telnet on port 110 I get the error: +OK Dovecot ready. user richard(a)richardaharwood.com +OK pass password -ERR Authentication failed. It seems to dislike the fact I specify the domain as part of the login username. If I repeat and login as: user richard - I am authenticated, however I get the error: -ERR [IN-USE] Couldn't open INBOX: Internal error occurred. Refer to server log for more information. Tailing the maillog, I see the following: Aug 8 17:19:01 richardaharwood dovecot: auth(default): client in: AUTH 1 PLAIN service=pop3 secured lip=83.170.110.193 rip=83.170.110.193 lport=110 rport=58115 resp=<hidden> Aug 8 17:19:01 richardaharwood dovecot: auth(default): passwd-file(richard,83.170.110.193): lookup: user=richard file=/etc/passwd.dovecot Aug 8 17:19:01 richardaharwood dovecot: auth(default): client out: OK 1 user=richard Aug 8 17:19:01 richardaharwood dovecot: auth(default): master in: REQUEST 4 3603 1 Aug 8 17:19:01 richardaharwood dovecot: auth(default): passwd(richard,83.170.110.193): lookup Aug 8 17:19:01 richardaharwood dovecot: auth(default): master out: USER 4 richard system_groups_user=richard uid=500 gid=500 home=/home/richard Aug 8 17:19:01 richardaharwood dovecot: POP3(richard): Effective uid=500, gid=500, home=/home/richard Aug 8 17:19:01 richardaharwood dovecot: POP3(richard): mbox: data=/var/spool/mail/vhosts/:INBOX=/var/spool/mail/vhosts//richard Aug 8 17:19:01 richardaharwood dovecot: POP3(richard): fs: root=/var/spool/mail/vhosts, index=, control=, inbox=/var/spool/mail/vhosts//richard Aug 8 17:19:01 richardaharwood dovecot: POP3(richard): open(/var/spool/mail/vhosts//richard) failed: Permission denied (euid=500(richard) egid=500(richard) missing +x perm: /var/spool/mail/vhosts/) Aug 8 17:19:01 richardaharwood dovecot: POP3(richard): Couldn't open INBOX: Internal error occurred.

I also notice the effective uid/gid is not that specified in the passwd file? The uid/gid appears to be that of my own ssh account which is not connected to the mail account that I wish to simply access as a virtual user. Would anyone be kind enough to point me in the right direction? In a nutshell, where am I going wrong with my authentication? This is a basic setup for the time being, until I get my head around it, but any pointers would be really appreciated. Have spent quite a few hours but I don't feel much closer to getting to the bottom of it! :) Many thanks, Richard

[Dovecot] multiple auth-client sockets
by LEVAI Daniel 09 Aug '09

09 Aug '09

Hi! I'm gonna need to use dovecot's auth-client socket in an authentication program. Now the auth-client socket is only used by my MTA, which is postfix. Because postfix's smtpd process (which uses the auth-client socket) runs chrooted under postfix's spool directory, I must create the auth-client socket under that spool directory. However, to reach that socket from another chrooted program is impossible. Can I create multiple instances of auth-client sockets? I tried to define another client {} stanza in socket listen {} in dovecot.conf, but only the last client socket got created. I need only a true or false response from dovecot regarding the authentication, and I thought that this is exactly what auth-client socket will do. However, if I can not reach it, is there any alternative to this? What's up with the auth-master or auth-worker sockets? Are they capable of respond to an auth request too? btw, I'm running dovecot-1.2.3 Thanks!

[Dovecot] autocreate plugin fails to subscribe mailbox in public namespace

Hi, I'm one step away from replacing a 7 years old qmail/uw-imapd setup with some state of the art soft- and hardware. We got migration scripts and test almost done - just one thing that keeps failing: The autocreate plugin is supposed to subscribe new users to different mailboxes, one of them being in namespace "Public." - this subscription to "Public.announcements" fails. Below is a dovecot -n - and no, there are no error messages in the logs. # 1.2.2: /etc/dovecot/dovecot.conf # OS: Linux 2.6.30-bpo.1-amd64 x86_64 Debian 5.0.2 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps managesieve listen(default): *:143 listen(imap): *:143 listen(managesieve): * ssl_listen(default): *:993 ssl_listen(imap): *:993 ssl_listen(managesieve): ssl_cert_file: /etc/ssl/owncerts/snakeoil.crt ssl_key_file: /etc/ssl/private/snakeoil.key login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login verbose_proctitle: yes mail_privileged_group: vmail mail_location: maildir:~/Maildir mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_process_size: 384 mail_plugins(default): quota imap_quota fts fts_squat acl autocreate expire trash mail_plugins(imap): quota imap_quota fts fts_squat acl autocreate expire trash mail_plugins(managesieve): mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(managesieve): /usr/lib/dovecot/modules/managesieve namespace: type: private separator: . inbox: yes list: yes subscriptions: yes namespace: type: public separator: . prefix: Public. location: maildir:/export/vmailboxes/public:INDEX=~/Maildir/public list: yes lda: postmaster_address: postmaster(a)test.cite.lan hostname: testvm06.test.cite.lan mail_plugins: quota sieve expire trash auth_socket_path: /var/run/dovecot/auth-master auth default: mechanisms: plain login cram-md5 passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: sasl master: path: /var/run/dovecot/auth-master mode: 384 user: vmail group: vmail plugin: quota: maildir:User quota quota_warning: storage=90%% /usr/local/bin/quota-warning.sh 90 quota_warning2: storage=95%% /usr/local/bin/quota-warning.sh 95 sieve: ~/.dovecot.sieve sieve_storage: ~/sieve sieve_extensions: +imapflags fts: squat fts_squat: partial=4 full=10 acl: vfile autocreate: Trash autocreate2: Drafts autocreate3: Sent autocreate4: learn-spam autosubscribe: Trash autosubscribe2: Drafts autosubscribe3: Sent autosubscribe4: learn-spam autosubscribe5: Public.announcements autosubscribe6: INBOX expire: Trash 60 Trash/* 60 expire_dict: proxy::expire trash: /etc/dovecot/dovecot-trash.conf dict: expire: pgsql:/etc/dovecot/dovecot-dict-expire.conf Any hints are really appreciated.

Only ~1000 users, but still...

[Dovecot] Creating a "default" domain
by Charles Sprickman 09 Aug '09

09 Aug '09

Hello, I'm setting up a test server to work through the issues involved in bringing a bunch of vpopmail/qmail/courier users into a postfix/dovecot server. So far I'm seeing lots of info to aid in the transition. One thing I'm lost on is that since Dovecot is providing all the auth mechanisms rather than vpopmail, I'm not sure how to emulate a particular vpopmail behavior we rely on. Vpopmail allows for the concept of a "default" domain for authentication. So if I have a bunch of domains, and one is "example.com", users in that domain can login with only the username part of their id (ie: "john") rather than supplying the domain (ie: "john(a)example.com"). I need to continue to offer this unless I want to walk a few hundred users through reconfiguring their mail clients. :) Any pointers?

[Dovecot] convert config from 1.1.2_1 to 1.1.16
by Ebbe Hjorth 09 Aug '09

09 Aug '09

Hi, Im tryin to follow a guide, telling me howto setup freebsd with postfix and dovecot. The text in bold (first section), is what the guide says, and the text that follows is what the /usr/local/etc/dovecot.conf files says. Can you please help me on how to convert from the 1.1.2_1 setup to the correct configuration for the 1.1.16? / Thank you very much. *socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } * socket listen { master { # Master socket provides access to userdb information. It's typically # used to give Dovecot's local delivery agent access to userdb so it # can find mailbox locations. path = /var/spool/postfix/private/auth mode = 0600 # Default user/group is the one who started dovecot-auth (root) #user = #group = } client { # The client socket is generally safe to export to everyone. Typical use # is to export it to your SMTP server so it can do SMTP AUTH lookups # using it. path = /var/run/dovecot/auth-client mode = 0660 }
