[Dovecot] Dovecot 2.0beta4 changset 11014 dict: Panic: file driver-mysql.c

Hi, With the latest hg version I see panics with dict process whenever a message is received via lmtp. This didn't happen with the original beta4 release. Mar 27 11:45:51 ubuntu-test dovecot: dict: mysql: Connected to localhost (mails) Mar 27 11:45:51 ubuntu-test postfix/lmtp[5261]: 0F22B27F0D: to=<test(a)ubuntu-test.localdomain>, orig_to=<test(a)ubuntu-test.localdomain>, relay=ubuntu-test.localdomain[dovecot-lmtp], delay=0.41, delays=0.06/0.01 /0.22/0.11, dsn=2.0.0, status=sent (250 2.0.0 <test(a)ubuntu-test.localdomain> WsNlE9/hrUuOFAAA7I0XzQ Saved) Mar 27 11:45:51 ubuntu-test dovecot: master: service(dict): child 5263 killed with signal 6 (core not dumped) Mar 27 11:45:51 ubuntu-test dovecot: master: service(dict): command startup failed, throttling Mar 27 11:45:51 ubuntu-test dovecot: lmtp(5262, test): WsNlE9/hrUuOFAAA7I0XzQ: sieve: msgid=<4BADE1E9.7000709(a)ubuntu-test.localdomain>: from=test(a)ubuntu-test.localdomain: stored mail into mailbox 'INBOX' Mar 27 11:45:51 ubuntu-test dovecot: dict: Panic: file driver-mysql.c: line 633 (transaction_send_query): assertion failed: (rows != (my_ulonglong)-1) Mar 27 11:45:51 ubuntu-test dovecot: dict: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0 [0xb773dd92] -> /usr/lib/dovecot/libdovecot.so.0 [0xb773ddff] -> /usr/lib/dovecot/libdovecot.so.0(i_erro r+0) [0xb77198ee] -> dovecot/dict [0x80506aa] -> dovecot/dict [0x80506e6] -> dovecot/dict(sql_transaction_commit_s+0x20) [0x804f730] -> dovecot/dict [0x804de42] -> /usr/lib/dovecot/libdovecot.so. 0(dict_transaction_commit_async+0x2f) [0xb771e4ff] -> dovecot/dict [0x804c930] -> dovecot/dict [0x804c35d] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0xe2) [0xb774a2d2] -> /usr/lib/d ovecot/libdovecot.so.0(io_loop_run+0x30) [0xb7749320] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x2a) [0xb7736dfa] -> dovecot/dict(main+0x19c) [0x804d00c] -> /lib/tls/i686/cmov/libc. so.6(__libc_start_main+0xe6) [0xb72dab56] -> dovecot/dict [0x804c051] Mar 27 11:45:51 ubuntu-test postfix/qmgr[2335]: 0F22B27F0D: removed Mar 27 11:45:51 ubuntu-test dovecot: lmtp(5262): read(/var/run/dovecot/dict) failed: Remote disconnected Mar 27 11:45:51 ubuntu-test dovecot: lmtp(5262): Disconnect from local: Client quit Thanks, e-frog ------------------------------------------------------------------------- # 2.0.beta4: /etc/dovecot/dovecot.conf # OS: Linux 2.6.31-20-generic-pae i686 Ubuntu 9.10 auth_debug = yes auth_socket_path = /var/run/dovecot/auth-userdb auth_username_format = %Ln deliver_log_format = msgid=%m: from=%f: %$ dict { dictionary = mysql:/etc/dovecot/dovecot-dict-sql.conf } disable_plaintext_auth = no lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes mail_debug = yes namespace { hidden = no inbox = yes list = yes location = prefix = separator = / subscriptions = yes type = private } namespace { location = virtual:/etc/dovecot/virtual:INDEX=~/.maildir/control prefix = virtual/ separator = / subscriptions = no type = private } passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { fts = squat fts_squat = partial=4 full=10 quota = dict:user::proxy::dictionary sieve = ~/.dovecot.sieve sieve_before = /etc/dovecot/sieve-global/ sieve_dir = ~/.sieve } postmaster_address = postmaster@ubuntu-test protocols = imap lmtp managesieve quota_full_tempfail = yes sendmail_path = /usr/lib/sendmail service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { mode = 0666 } } service dict { unix_listener dict { mode = 0666 } } service lmtp { unix_listener /var/spool/postfix/dovecot-lmtp { group = postfix mode = 0660 user = postfix } } service managesieve-login { inet_listener sieve_deprecated { port = 2000 } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } verbose_proctitle = yes protocol managesieve { mail_plugins = virtual } protocol lmtp { mail_plugins = virtual quota sieve } protocol lda { info_log_path = /var/log/deliver.log log_path = /var/log/deliver.log mail_plugins = virtual quota sieve } protocol imap { mail_plugins = quota imap_quota fts fts_squat virtual }

Probably depends on what city/state/province/country as well. I'm in the midwest USA, and alot of people in general, sysadmins or not, are DIY type folks. You grow up on a farm or in a small town and learn a whole lot of non computer stuff (including basic woodworking) before going to college and then to the big city for the sysadmin job. Then you visit mom/dad on the weekends, and they have you rebuilt the kitchen and bathroom. Then you decide to rebuild your own kitchen and bathroom.

You think anyone is going to add the user "pigeon" to any groups? I'm thinking that, as with "dovenull", that most would avoid touching "pigeon" at all costs. Then again, some may think their system was hacked, and want to remove the user "pigeon" lol. If your main goal is getting people to leave that user alone, I think pigeon would definitely fit the bill. And it adds a bit of humor to the mix since pigeons tend to crap all over everything. ;) >> dovecot dove-main >> dovecot-auth dove-auth >> imap-login dove-imaplgn >> pop3-login dove-poplgn >> imap dove-imap >> pop3 dove-pop3 >> >> Just a thought.

I wouldn't know why some process is owned by user "dovel". That might not even make me realize it's a Dovecot process. How about "pigeon"? Dovecots house two kinds of birds, doves, and, far more often, pigeons. So, pigeon should be the new user name. No one knows what the heck a "dovecot" is until they look it up anyway (at least non Scots), so using "pigeon" is in keeping with naming your server Dovecot. There. Now that that's settled... Kinda related to the current subject, naming things, I personally believe renaming all of the processes with a "dove-" or similar at the start of the process name would be nice. I wish Wietse would do so with Postfix as well, although I've not mentioned it (yet). Something like this: dovecot dove-main dovecot-auth dove-auth imap-login dove-imaplgn pop3-login dove-poplgn imap dove-imap pop3 dove-pop3 Just a thought. But a nice thought at that. :) -- Stan

[Dovecot] corrupted mbox
by Jernej Porenta 27 Mar '10

27 Mar '10

Heya, we have two IMAP (UW-imap and dovecot) servers accessing the same mbox files for our users (don't ask why) and sometimes the UW-imap corrupts the mbox file. The mbox looks just like normal mbox except it does not have the proper 'From ' beginning of the file (usually there are some random tidbits in the begining of the file, which can be easily stripped to recover the working mbox). The problem is that if we use dovecot for POP3 server, the dovecot logs the mbox corruption just fine: POP3(username): Couldn't init INBOX: Mailbox isn't a valid mbox file But if we use IMAP for the same mailbox, dovecot opens the file and does not report any corruption, the user on the other hand sees just empty mailbox. So I was wondering if there are any possibilities to report mbox corruption with IMAP as well? thanks in advance, regards, Jernej

Hi, It's not clear from the configuration when CR/LF conversion happens with mail_save_crlf set. Does this only happen with appends, or do all mails handled by Dovecot always get converted when opened? Cheers, Sabahattin

[Dovecot] cmusieve auto-reply and quota
by Mauro Faccenda 27 Mar '10

27 Mar '10

Hi there, I'm quite new to Dovecot, but already can tell that it is a really great work, congrats to the developers! But I'm having a little problem and couldn't figure it out how to solve. First, let me talk about my setup: I'm running Debian 5 (Lenny) with it's default Dovecot (common, pop3 and imap) packages (version 1:1.0.15-2.3+lenny1), I really would like to keep it this way unless I haven't another option. All authentication is made through a MS Active Directory and messages delivered to a virtual mailbox (/var/vmail/<domain>/<mailbox>), using Postfix as SMTP, that uses procmail (just for filtering the messages, not to deliver) that calls Dovecot's deliver like this: -- :0 w | $DELIVER -d $RECIPIENT -e -- $DELIVER points to /usr/lib/dovecot/deliver and $RECIPIENT is fed by Postfix in it's master.cf All this work great. Then I needed to enable quotas it's working as well. Here is the section that show how I've set it up: -- protocol lda { mail_plugin_dir = /usr/lib/dovecot/modules/lda mail_plugins = cmusieve quota postmaster_address = postmaster(a)do.ma.in hostname = mybox.do.ma.in auth_socket_path = /var/run/dovecot/auth-master quota_full_tempfail = no } -- I also want to run some sieve scripts just to be able to do some auto-replies (i.e. Out of office), and also it works well. Here is an example of a sieve I was using in some tests: -- require ["fileinto", "vacation"]; if header :contains "X-DSPAM-Result" "Spam" { stop; } vacation :days 1 :subject "Out of office reply" :addresses ["john.doe(a)do.ma.in", "jd(a)do.ma.in"] "I'm out of office, please contact Joan Doe instead. Best regards John Doe"; -- And as I said it works. But when I send a message to this mailbox that could exceed it's quota I get this on my logs: -- Mar 25 14:02:25 mybox postfix/pickup[21407]: 68D1DA82F: uid=103 from=<> Mar 25 14:02:25 mybox deliver(john.doe(a)do.ma.in): msgid=<4BAB9728.6000601(a)other.do.ma.in>: sent vacation response to <faccenda(a)other.do.ma.in> Mar 25 14:02:25 mybox postfix/cleanup[22119]: 68D1DA82F: message-id=<dovecot-1269536545-332912-0(a)do.ma.in> Mar 25 14:02:25 mybox postfix/qmgr[17299]: 68D1DA82F: from=<>, size=623, nrcpt=1 (queue active) Mar 25 14:02:25 mybox deliver(john.doe(a)do.ma.in): msgid=<4BAB9728.6000601(a)other.do.ma.in>: save failed to INBOX: Quota exceeded Mar 25 14:02:25 mybox deliver(john.doe(a)do.ma.in): sieve runtime error: Keep: Generic Error Mar 25 14:02:25 mybox deliver(john.doe(a)do.ma.in): sieve_execute_bytecode(/var/vmail/do.ma.in/john.doe/.dovecot.sievec) failed Mar 25 14:02:25 mybox deliver(john.doe(a)do.ma.in): msgid=<4BAB9728.6000601(a)do.ma.in>: Rejected: Quota exceeded Mar 25 14:02:25 mybox postfix/pipe[22086]: 7C666A825: to=<john.doe(a)do.ma.in>, relay=procmail, delay=1.1, delays=0.39/0/0/0.68, dsn=4.3.0, status=deferred (temporary failure) -- And every time the server tries again to deliver that message it re-sends the auto-reply. Is it an undesirable behavior, isn't it? Does anyone knows how to address it? Also, I thought that that configuration (using the -e parameter to deliver) and the "quota_full_tempfail = yes" would make give an permanent error, not trying to deliver that message again. What is wrong about it? Thanks in advance,

[Dovecot] A questions about consume_results (driver-pgsql.c)

27 Mar '10

Code -------------- static void consume_results(struct pgsql_db *db) { do { if (!PQconsumeInput(db->pg)) break; if (PQisBusy(db->pg)) return; } while (PQgetResult(db->pg) != NULL); if (PQstatus(db->pg) == CONNECTION_BAD) io_remove_closed(&db->io); else io_remove(&db->io); db->querying = FALSE; if (db->queue != NULL && db->connected) queue_send_next(db); } --------------- This is the only part of the driver-pgsql.c code where a CONNECTION_BAD does not result in driver_pgsql_close being called. This will likely happen after the next query (from queue or a new one) failed because the connection was bad. Is there a reason for this?

[Dovecot] v2.0.beta4 released
by Timo Sirainen 27 Mar '10

27 Mar '10

http://dovecot.org/releases/2.0/beta/dovecot-2.0.beta4.tar.gz http://dovecot.org/releases/2.0/beta/dovecot-2.0.beta4.tar.gz.sig I think this release is finally feature complete. There are still some bugs left to be fixed, but it's mainly in the dsync/mdbox area. v2.0.rc1 should hopefully be out in a couple of weeks. After that v2.0.0 will be released after no serious bugs have been found for a couple of weeks. Major changes since beta3: - auth process now runs as $dovecot_internal_user ("dovecot") by default. Auth worker processes still run as root by default, so this won't break PAM etc, but it could break passwd-file configurations. - It can now read v1.2's dovecot.conf file. If you find that it won't read your config, let me know and I'll see about adding code to fix it. It'll log warnings about each obsolete setting it sees. The easiest way to get rid of the warnings is to just translate your old config to v2.0: doveconf -n -c old.conf > new.conf - auth passdb/userdb configuration in example-config is now a bit different .. hopefully less confusing to new people than the old one. - added support for auth settings (including passdb/userdb) inside protocol sections, so it'll affect only those protocols - mail_plugins can now be set more easily. you can have a single global mail_plugins and then add more plugins to it like protocol imap { mail_plugins = $mail_plugins imap_quota } - doveconf finally shows all settings, including all protocol, local and remote sections - doveadm quota get|recalc command added. This is a plugin (yeah, doveadm now supports plugins!), so you must have a global mail_plugins=quota setting for the command to show up. - doveadm kick user/network to kick out logged in users (by sending TERM signal to processes). This was written by Pascal Volk. - and of course tons and tons of fixes all around

[Dovecot] CentOS yum update causing died unexpectedly
by dovecot＠corwyn.net 26 Mar '10

26 Mar '10

Running CentOS 5.x running a postfix/dovecot implementation. Dovecot 1.1.8. I just ran a full system update in my dev environment, and now I'm occasionally getting: Mar 26 07:15:43 example dovecot: auth(default): worker-server(test222(a)int.example.com,127.0.0.1): Aborted: Worker process died unexpectedly in /var/log/maillog.

Hello, i use successfully mysql-quotasystem with dovecot 1.2.11 on different servers except for mysql 4.0 servers dovecot internally uses sql: "ON DUPLICATE KEY UPDATE" which was introduced in mysql 4.1 Is there a chance to make this statement mysql 4.0 compatible or should i update mysql? i want to avoid updating mysql because some old software is running which is not compatible to higher mysql versions.

[Dovecot] Dovecot 2.0beta4
by Renaud Allard 25 Mar '10

25 Mar '10

Hello, It seems dovecot 2.0 beta4 still behave strangely without tcpwrap. I still get the errors: 2010-03-25_17:26:59.33848 Fatal: service(tcpwrap) access(/opt/dovecot/libexec/dovecot/tcpwrap) failed: No such file or directory 2010-03-25_17:27:00.36108 Fatal: service(tcpwrap) access(/opt/dovecot/libexec/dovecot/tcpwrap) failed: Permission denied It's easy to solve by touching and chmodding 0755 that file, but prod version shouldn't exhibit that behavior.

[Dovecot] 1.2.11 nfs_flush_file_handle_cache_dir problems
by Ade Fewings 25 Mar '10

25 Mar '10

Hi chaps We're using the mbox_snarf plugin to snarf mail from /var/mail/%U to ~%U/Mail/inbox and using dotlocking on all accesses. This is on Solaris with NFS mounted home directories. We're getting a few (very few) of these for just a couple of users: Error: nfs_flush_file_handle_cache_dir: rmdir(/var/mail) failed: Device busy Which, having searched, I see some discussion of in the past, but not with 1.2. We're using: mail_privileged_group = mail For the /var/mail 'inboxes', which I thought would tackle this problem. Couple of questions, if you don't mind: 1. Does dovecot user need to be a member of the mail group? 2. Does this error message represent a real problem that needs solving? It's very strange how rare it is and that only a few select users have encountered.

[Dovecot] Dovecot-1.2 + Sieve + Managesieve on Debian
by Proskurin Kirill 25 Mar '10

25 Mar '10

Hello! I think about migrate from FreeBSD to Linux because I need DRBD for clustering. I want to use Debian Lenny but run on some problems. I want near latest Dovecot packages. Native repos are too old. Backports seems to don`t have a Sieve&Managesieve support and we need it(am I wrong?). Stephan Bosch auto packeges is not for production. How could I solve this without make own packages? What Debian folk`s do in this situation? P.S. I don`t want to use RedHat like OS because I not familiar with it. -- Best regards, Proskurin Kirill

[Dovecot] can Dovecot do VERP?
by Rick Graves 25 Mar '10

25 Mar '10

Hey, I have several thousand email addresses, the vast majority of which are definitely no good, and I want to figure out which are good. So I will send out an email to all the email addresses. By making a list of the ones that bounced, and comparing that list with the full list, I can determine which are still good. This is for a non-profit association -- I am not in the spam business. Knowing exactly which emails bounced would be much easier if I could set up an in box implementing VERP. http://en.wikipedia.org/wiki/Variable_envelope_return_path In other words, I want an in box accepting all mail where the email addresses match a wildcard pattern like this: mail_admin_??????(a)domain.org, where ?????? are 6 digits. The digits would be a scrambled contact ID. Since they will be digits only, here is the regular expression: mail_admin_\d{6}. (We will pick a wildcard pattern that does not conflict with any existing address on the server.) Sending the outgoing emails, each with a different "From" address matching the wildcard pattern, is not a problem -- I have a working python script for this. The challenge is getting one in box to accept emails with different "From" addresses (matching the wildcard pattern). We are running IMAP server Dovecot 1.0.7. How do I set this up in the IMAP server to accept emails to addresses matching the wildcard pattern? Thanks, Rick Graves

Re: [Dovecot] quota dict with mysql 4.0

(sorry, i only read the digest version of list and always create i new thread by "fake-Re") Hello, >> Perhaps you can implement some updating procedure that >> would only involve a percentage of your users at one time. no way, i want to fix this! but i need help because i have no idea of c-programming. i can read the code a little bit, but never lerned it. solution is to edit dovecot-1.2.11/src/lib-dict/dict-sql.c i can avoid using ON DUPLICATE KEY UPDATE by changing line 91 to: orig: dict->has_on_duplicate_key = strcmp(driver->name, "mysql") == 0; changed: dict->has_on_duplicate_key = strcmp(driver->name, "mysqlXXX") == 0; this works only 50%. if a user has no entry in quotatable, dovecot is updating his quota with 2 queries: INSERT INTO quota (bytes,username) VALUES ('2456','myuser') INSERT INTO quota (messages,username) VALUES ('2','myuser') The first query works, the second throws an error because username-field is uniqe. Duplicate entry 'myuser' for key 1 So i have to find a way to make this query in one step: INSERT INTO quota (bytes,messages, username) VALUES ('2456','2','myuser') or turn the second insert into an update update quota SET messages='2' where username='myuser' But iam afraid this is too much for my c-skills. I need help of an C-Crack or timo as developer. if timo could create a switch for mysql 4.0 would surely be the best. Thanks, Andre

Re: [Dovecot] quota dict with mysql 4.0
by Andre Hübner 25 Mar '10

25 Mar '10

Hello, >> I am somewhat surprised that the older software is not compatible with >> the newer version of MySQL. Usually, it is the other way around. Have >> you checked to see if newer versions of the incompatible software >> exist? I would be willing to wager that they have been updated to >> accommodate the newer MySQL versions. Syntax changed a litte bit and also there are some new protected words which are used by older software in sql without backticks etc. I agree updating would be the better way but we talking about a big number of servers and customers still using it. this is not changed over night.... I looked into dovecot-1.2.11/src/lib-dict/dict-sql.c, there seems to be a check for "ON DUPLICATE KEY UPDATE" on line 588. I recompiled dovecot on mysql 4.0 machine and tried again but there was no change. SQL is successful when dataset in quotatable is existing. in this case dovecot triggers an update of the data. But if no line for user is existing in quotatable and an insert is needed there is still the error: sql dict: commit failed: You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near 'ON DUPLICATE KEY UPDATE bytes='12525'' at line why is the mysql 4.0-recompiled dovecot thinking my mysql is able to do "ON DUPLICATE KEY UPDATE"? How to avoid this? Thanks, Andre

[Dovecot] Question howto wiki.dovecot.org about quotas using dict
by Ricardo Barbosa 24 Mar '10

24 Mar '10

Hi, I am configuring a server with postfix and dovecot with virtual domains and using quota. To implement quota followed the documentation of the link http://wiki.dovecot.org/Quota/Dict, did not understand what you mean the field "where_field = path" would be the path on the filesystem of your mailbox? I would have to create the table that he says in the documentation or can I force a value with concat and using the AS (ie select '/var/vmail/domain/user' as path from table) ?

[Dovecot] Is it possible to prevent users from ever deleting anything?
by Snaky Love 24 Mar '10

24 Mar '10

Hi, dear dovecot-users, is it possible to make dovecot ignore the DELETE command for some accounts? Basically what I want to achieve is: users shall not be able to delete their emails - but they still should be able write emails. This is meant for a setup where different users are sending and receiving emails for a "support" account. I looked into IMAP virtual folders and ACL but I did not see a way of totally disabling the possibility to delete emails and share the whole account. I realize there may be race conditions with a setup like this and a web based ticket system might be a better solution, but it is only a very small team and we can always talk to each others to resolve conflicts - so using only one mail account for support seems practical and could keep the overhead small - but we do not want to delete anything from it (accidentaly). Of course, at one point in future somebody has to delete some mails from this accounts to get rid of old stuff - so I would like to implement a super-user that is able to do that kind of mailbox maintanance. How would I use ACL to setup such a scenario? Is it even possible? Or did I misunderstand IMAP shared folders completely??? Thank you very much for your attention! Have a nice day, Snaky

[Dovecot] Writing "sieve" script
by Jerry 24 Mar '10

24 Mar '10

This is probably not the best place to ask this question; however, I figured I had to start somewhere. I want to write a sieve script that can sort incoming mail into specific locations. EXAMPLE: require ["fileinto"]; if header :contains "X-Virus-Status" "Infected" {fileinto "SPAM"; stop;} elsif header :contains "X-SpamCop-Disposition" "Blocked" {fileinto "SPAM"; stop;} elsif address :contains "To" "user1(a)domain.com" {fileinto "INBOX.user1";} elsif address :contains "To" "user2(a)domain.com" {fileinto "INBOX.user2";} elsif address :contains "To" "user3(a)domain.com" {fileinto "INBOX.user3";} # The rest goes into INBOX # The default is "implicit keep", we do it here explicitly else {keep;} This works fine unless user1, user2 and or user3 are all included in the same e-mail address. It is rare; however, it does happen. In that case, a separate message for each recipient would be delivered to the first matching mailbox. The other recipients would not receive any traffic at all. I am new at writing sieve scripts, and have not come up with any way of preventing this from happening. If anyone has a suggestion, I would love to hear it. Even the examples I found by Googling were not really informative. -- Jerry Dovecot.user(a)seibercom.net Disclaimer: off-list followups get on-list replies or get ignored.

[Dovecot] Removing Duplicates
by Sabahattin Gucukoglu 23 Mar '10

23 Mar '10

Hi all, I am starting fresh with a local repository of mails, which almost certainly have duplicates in them. I am going to use maildirs, and ensure all mails are input with CRLFs. The question is: does anybody know how I can find and remove duplicates, either while injecting mail with IMAP, or afterward? I can use tools to find duplicate Message-IDs, but don't know of a way to remove duplicates in mailboxes that are already imported as opposed to incoming mail. Perhaps there is a way to use the IMAP protocol for this? Cheers, Sabahattin

I'd say it was production, yes, but I'm forgiving of problems in the latest releases, so long as they aren't meant to be beta (i.e., known breakages). Cheers, Sabahattin

[Dovecot] dovecot-2.0.beta4 mysql support in Solaris
by Tomi Vainio 22 Mar '10

Hi, I've been able to configure --with-mysql in Solaris 10 which has MySQL version 4.0.31 bundled in. Since beta4 build fails due to change in src/lib-sql/driver-mysql.c. I've never used this feature but so I don't need it. This is just a FYI if someone reads mailing list.

[Dovecot] Shared mailboxes basics
by Thomas Hummel 22 Mar '10

22 Mar '10

Hello Timo, I'm trying to set up shared mailboxes with dovecot-1.2.11/Maildir. I previsouly used public namespaces with 1.1+ to somehow implement them but I'm looking at the real ones now. I've read the Wiki but I'm still confused or not 100% sure about the following (basic) points : 1. Namespaces prefixes My understanding is that a namespace prefix is just an escape mechanism for the client to access the mailboxes this namespace holds. So the real location is _only_ defined by the "location" directive, independently of what the prefix is. So, for example, If you've got : prefix="foo/bar/" location=maildir:/some/folder/%u mailboxes are physically in /some/folder/%u, not in /foo/bar/some/folder/%u or something am I correct ? 2. Other Users mailboxes RFC234 states that shared mailboxes (which they call "Other Users" mailboxes) are "mailboxes from the Personal Namespaces of other users." Dovecot's Wiki takes as an example : # User's private mail location. mail_location = maildir:~/Maildir # You need to create also a private namespace: namespace private { separator = / prefix = #location defaults to mail_location. inbox = yes } namespace shared { separator = / prefix = shared/%%u/ location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u subscriptions = no list = children } and states : "This creates a shared/ namespace under which each user's mailboxes are." My understanding is that # User's private mail location. mail_location = maildir:~/Maildir and location = maildir:%%h/Maildir implies that mailboxes in both the private and the shared/ namespace are physically in the same location (under the "$HOME/Maildir" directory of the user who shares his mailbox) . Am I correct ? I tried the following set up : namespace private { separator = / location = maildir:/courriel/boites/%u:CONTROL=/courriel/meta/%u:INDEX=/var/dovecot-test/indexes/%1u/%u inbox = yes hidden = no list = yes subscriptions = yes } namespace shared { separator = / prefix = "#shared/%%u/" location = maildir:/courriel/boites/%%u:INDEX=/var/dovecot-test/indexes/%1u/%u/shared/%%u subscriptions = no list = yes # will try children later } the user doveimap has the following mailboxes : # pwd /courriel/boites # ls -l doveimap total 64 drwx------ 5 doveimap Invites 4096 Oct 23 13:38 .Trash drwxr-xr-x 5 doveimap Invites 4096 Oct 27 17:00 .sous drwxr-xr-x 5 doveimap Invites 4096 Oct 27 17:00 .sous.arbo drwxr-xr-x 5 doveimap Invites 4096 Oct 27 17:00 .sous.arbo.rescence drwx------ 5 doveimap Invites 4096 Oct 23 13:43 .testcopy drwx------ 2 doveimap Invites 4096 Mar 15 17:08 cur drwx------ 2 doveimap Invites 4096 Mar 15 17:07 new drwx------ 2 doveimap Invites 4096 Mar 15 17:07 tmp I can perform for instance : * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN] Dovecot test ready. x login doveimap xxxxxxxx x OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS ACL RIGHTS=texk] Logged in 1 setacl INBOX dovepop rl 1 OK Setacl complete. But isn't a client like Thunderbird (3.0.3) supposed to . show me the #shared (even if no one shares mailboxes to me) "folder" (because of list = yes )? . let me share, let's say the .sous.arbo mailbox ? If yes, how ? Or should I first pre-set some acl files ??? For now, it says : "This is a personnal mail folder. It is not shared."

[Dovecot] dovecot-2.0.beta3 tcpwrapper support in Solaris
by Tomi Vainio 22 Mar '10

22 Mar '10

Hi, 2.0 compiles fine in Solaris but and I've found only one glitch so far. Tcpwapper support needs some tweaks. I need to add CPPFLAGS=/usr/sfw/include because tcpd.h is in there. Then also LDFLAGS='-R/usr/sfw/lib -L/usr/sfw/lib' is needed. It would be nice to have --with-tcpwrap-dir or something. After this linking gives an error Undefined first referenced symbol in file deny_severity /usr/sfw/lib//libwrap.so allow_severity /usr/sfw/lib//libwrap.so These are not defined but application itself should define these globally so I've added these to configure and src/util/tcpwrap.c #include <syslog.h> int allow_severity = LOG_INFO; int deny_severity = LOG_WARNING; Tomppa

[Dovecot] Dovecot 1.2.11 renames Maildir filenames on first read of foreign POPstore - how to avoid
by Sam C. Nicholson !! 22 Mar '10

22 Mar '10

Greetings, I'm converting from a custom POPstore ( > 100,000 messages) which is Maildir-like and uses the filename as the UIDL and doesn't store it inside the message. I'm wondering whether there is hope for config-file options to keep devecot from renaming files when it first sees them, or whether I'm going to need to create a new backend for dovecot based on Maildir. The renaming not only blows my current UIDLs, it seems to upset Dovecot's indexing, Cheers! -sam My POPstore looks like this: /zdata/domain/%d/folders/%n/{cur, new, tmp}/ and message filenames like this: msg.yyyy:mm:dd:hh:mm:ss.random I was able to get Dovecot to see the store by the symlink: INBOX -> . Here are the log messages regarding the index warnings: Mar 22 07:45:52 POP3(scion(a)6ix.net): Warning: Fixed a duplicate: /zdata/domain/6ix.net/folders/scion/INBOX/cur/msg.2008:02:20:16:37:56.951.2376 -> 1269258346.M323507P15988.mailbase Mar 22 07:45:52 POP3(scion(a)6ix.net): Warning: Fixed a duplicate: /zdata/domain/6ix.net/folders/scion/INBOX/cur/msg.2008:01:08:00:00:50.25142.18396 -> 1269258346.M323508P15988.mailbase ^ |____Dovecot message name appears to increment here #dovecot -c config -n # 1.2.11: /home/scion/Packages/dovecot-1211/dovecot.conf.short Warning: fd limit 256 is lower than what Dovecot can use under full load (more than 640).

[Dovecot] configure dovecot to read-only ?
by Frank Gadegast 22 Mar '10

22 Mar '10

Hi, I like to configure the use of IMAP to read-only on a special backup system. Users should only be able to read archived email, they should not be able to create folders or delete email. I know how to configure user- or folder-specific acls, but it seems to be a bit complicated to setup a ACL for every user. Any simple global option available ?

[Dovecot] Possible programming error in maildir_mail_get_save_date
by Rainer Weikusat 22 Mar '10

22 Mar '10

The maildir_mail_gate_save_date routine (lib-storage/index/maildir/maildir-mail.c) returns the save date when that was determined by looking at the ctime of the corresponding file. This is different from all other get_save_date routines which either return -1 if the date could not be determined or 0 to signal success. A particular problem caused by this would be that the first_nonexpunged_timestamp routine (plugins/expire/expire-plugin) never finds a not-yet-expired e-mail after the first message in a mailbox has been expunged when using the maildir storage and file ctimes for save dates, causing the expire_mailbox_transaction_commit function (same file) to delete expiry information for the mailbox in question from the expires table despite mails supposed to expire still exist.

[Dovecot] Public Folder for mailinglist with deliver
by Sebastian Heil 21 Mar '10

21 Mar '10

Hello Everybody, I'm looking for a nice way to implement the following: We are running a mail server for system users who are having their own mailbox. Now there's the idea to subscribe for a few mailinglists which are then available for the user per shared/public folder. So they can simply subscribe and unsubscribe with their MUA. For every mailinglist subscription there should exist an own email account with own mail directory. The namespaces are already working (in a test environment). But I haven't found any implementation to realize this nicely with deliver. The possiblities I'm thinking about are: -create a somewhere in userdb a passwd entry for each mailinglist email address with the corresponding directory -create a static userdb entry, but then deliver cannot check if an email address/mailbox exists. I think both ideas aren't a good implementation. So I'm asking you for help. Has someone a similar setup or a little idea how to make this work with deliver. Thanks in advance Sebastian

[Dovecot] Sendmail + deliver; silent errors.
by Daryl Tester 20 Mar '10

20 Mar '10

Hi all. I've got a bit of a peculiar issue here. I'm running dovecot 1.2.9 on an Ubuntu 9.10 box using Sendmail 8.14.3. I've set up Sendmail similar to <http://wiki.dovecot.org/LDA/Sendmail> except that *) dovecot's deliver is configured as my default local mailer, so some of the flags for the Mailer definition had to be adjusted accordingly. *) The setuid users listed in the wiki kept result in setgid() failures from deliver, so I've changed it to root:mail (mail being sendmail's MDA group), with permissions as u+s,g+rx,o-rwx When sendmail attempts delivery, I'm getting "deferred: deliver failed with EX_TEMP", but nothing recorded in the log files. I've embarrassingly widened the permissions of /var/log/dovecot and the files contained within to read/write everyone, just to ensure that whomever it's running as has access, but the log files aren't updated. The peculiar thing kicks in when I attempt to debug this. So far I have (amongst other things): *) Run deliver from the command line logged in as "mail". *) written a shell wrapper script to be able to confirm things like the user ID that was invoking deliver. *) both in the shell script, and as an mailer definition in sendmail, strace'd (using a setuid root binary) deliver to capture what it was doing. Whenever I do any of the above, deliver works perfectly, and appears to log correctly. It only appears to bork when no-one is watching it, which is quite frustrating when trying to fix it. Help? Configuration of dovecot follows: # 1.2.9: /etc/opt/dovecot-1.2.9/dovecot.conf # OS: Linux 2.6.31-14-server x86_64 Ubuntu 9.10 ext3 base_dir: /var/run/dovecot-1.2.9/ log_path: /var/log/dovecot/dovecot.log info_log_path: /var/log/dovecot/dovecot-info.log protocols: pop3 imap imaps ssl: no disable_plaintext_auth: no login_dir: /var/run/dovecot-1.2.9//login login_executable(default): /opt/dovecot-1.2.9/libexec/dovecot/imap-login login_executable(imap): /opt/dovecot-1.2.9/libexec/dovecot/imap-login login_executable(pop3): /opt/dovecot-1.2.9/libexec/dovecot/pop3-login mail_uid: vmail mail_gid: vmail mail_location: maildir:/vmail/spool/%u:LAYOUT=fs mail_executable(default): /opt/dovecot-1.2.9/libexec/dovecot/imap mail_executable(imap): /opt/dovecot-1.2.9/libexec/dovecot/imap mail_executable(pop3): /opt/dovecot-1.2.9/libexec/dovecot/pop3 mail_plugin_dir(default): /opt/dovecot-1.2.9/lib/dovecot/imap mail_plugin_dir(imap): /opt/dovecot-1.2.9/lib/dovecot/imap mail_plugin_dir(pop3): /opt/dovecot-1.2.9/lib/dovecot/pop3 lda: postmaster_address: postmaster(a)handcraftedcomputers.com.au auth_socket_path: /var/run/dovecot-1.2.9/auth-master auth default: verbose: yes passdb: driver: passwd-file args: /vmail/auth/passwd userdb: driver: static args: uid=vmail gid=vmail socket: type: listen master: path: /var/run/dovecot-1.2.9/auth-master mode: 384 user: vmail group: vmail -- Regards, Daryl Tester Member of the Amalgamated Australian Association Against Apostrophe Abuse.

[Dovecot] INBOX of a shared namespace appears to be always subscribed
by Holger Richter 20 Mar '10

20 Mar '10

In dovecot 1.2.10 I run into the following problem: Our users are entitled to share their personal mailboxes. This works. But if user A shares any of its mailboxes with user B, then dovecot always reports the INBOX of user A as subscribed by user B. No matter whether user B really subscribed the INBOX of A, or whether user A permitted user B the access to its INBOX. The problem is caused by the repeated call of LSUB. Starting with the second call LSUB always shows INBOX as subscribed. To reproduce: -> telnet imap.xx.yy 143 1 LOGIN user password 2 LSUB "" shared/* => shows shared/UserB/folderXX 3 LSUB "" shared/* => shows shared/UserB/INBOX shared/UserB/folderXX 4 LSUB "" shared/* => shows shared/UserB/INBOX shared/UserB/folderXX Regards, Holger

[Dovecot] problem with master db and dovecot-2.0.beta3
by Oliver Eales 19 Mar '10

19 Mar '10

Hello, i am currenty testing dovecot 2.0.beta3 and ran into a problem with the master-db setting. For our webmail access we are sucessfully using the following settings with dovecot-1.2.10 auth_master_user_separator =* auth default { mechanisms = plain passdb passwd-file { args = /etc/dovecot/passwd.masterusers master = yes pass = yes } passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } } when "converting" the settings to version 2.0 i tried the following: auth_mechanisms = plain auth_master_user_separator = * passdb { driver = passwd-file args = /etc/dovecot/passwd.masterusers master = yes pass = yes } passdb { driver = ldap args = /etc/dovecot/dovecot-ldap.conf } But when i try to login, the auth process gets stalled with the following log entry: auth: Fatal: Master passdb can't have pass=yes if there are no passdbs master: Error: service(auth): command startup failed, throttling Am i doing something wrong or is it problem with the 2.0-beta ?

[Dovecot] Triggering mailbox fetch
by Brian Candler 19 Mar '10

19 Mar '10

Greetings, I would like to migrate mailboxes into a Dovecot system by using an IMAP transfer from the old system - and I'd like this to take place automatically at the time the user first logs into the new system. I have a script which will perform an IMAP fetch and dump it into the local maildir. In courier-imap I could create a '.loginexec' file which is executed when the user logs in, and gets deleted if it completes successfully. I'm trying to find something similar for Dovecot. * fetchmail-wakeup is the right kind of idea, but I need it to stop running once mail has been transferred successfully once. It also needs different parameters for each user (e.g. user/pass used to login to the remote IMAP server) * The convert_mail plugin only works with local mail spools, as far as I can tell. I'm not sure how it determines whether conversion has already taken place (whether the target maildir already exists?) * autocreate only creates empty mailboxes Any of these might be a starting point for developing my own plugin, but does anyone here know of an existing one which would do the job? Thanks, Brian.

[Dovecot] Problem with quota recreation
by Uroš Gruber 19 Mar '10

19 Mar '10

Hi, I'm migrating from cyrus to dovecot 1.2.10 with cyrus2dovecot. I've setup quota with mysql dict and while testing delivery quota is working fine. The only problem is when i migrate mailbox from cyrus to dovecot and when bytes and messages is set to 0. I tried with x GETQUOTAROOT Inbox but the quota usage is not recalculated and when a new message is delivered quota is calculated only on the new message. Any help would be greatly appreciated. Best regards Uros

[Dovecot] ACL + shared-imap + nested AD groups
by Martin Ott 19 Mar '10

19 Mar '10

Hi, I'm looking for a solution to use nested AD groups for authorization in shared-imap folders(namespace public). As a simple hack to determine the (primary) groups of a user we use the following setup with a post-login script: in dovecot.conf ... protocol imap { mail_executable = /etc/dovecot/ldap_groups.sh ... ldap_groups.sh ACL_GROUPS=`ldapsearch -h ldapserver -p 3268 -s sub -D "cn=ldap mail, ou=user, ou=global, ou=xxx, dc=xxx, dc=local" -b "ou=xxx, dc=xxx, dc=local" "(&(sAMAccountName=$USER))" -LLL memberOf -w password | grep "memberOf: CN=" | sed 's/memberOf: CN=//' | sed 's/,OU=.*//' | tr "\n" "," | sed 's/, $//'` export ACL_GROUPS exec /usr/libexec/dovecot/imap $* Does anyone know, how to simply get the groups of groups with such a post-login script? Thanks, Martin

[Dovecot] 2.0beta3 10876:370ee9717a6c broke listen on literal IPv6 address
by Bernhard Schmidt 19 Mar '10

Hi, apparently the following change in dovecot hg * New revision (10876:370ee9717a6c) in dovecot Mercurial repository: - config: Forgot to add header file. broke listen = 83.170.6.69, 2001:1b10:1000::110:1:1 mail.svr02.mucip.net:~# dovecot -F -c /etc/dovecot/dovecot.conf doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:29: listen=..:port has been replaced by service { inet_listener { port } } doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf: duplicate listener: 1: Is this even possible? That doesn't make sense to me, but Stephan's +29 works fine for me, +30 (with just that change according to changelog) doesn't. Bernhard

[Dovecot] GlusterFs - Any new progress reports?
by Ed W 18 Mar '10

18 Mar '10

GlusterFs always strikes me as being "the solution" (one day...). It's had a lot of growing pains, but there have been a few on the list had success using it already. Given some time has gone by since I last asked - has anyone got any more recent experience with it and how has it worked out with particular emphasis on Dovecot maildir storage? How has version 3 worked out for you? Anyone had success using some other clustered/HA filestore with dovecot who can share their experience? (OCFS/GFS over DRBD, etc?) My interest is more in bootstrapping a more highly available system from lower quality (commodity) components than very high end use Thanks Ed W

Re: [Dovecot] sieve vacation
by Martin F. Foster 18 Mar '10

18 Mar '10

Following from Steffen Kaiser's response, RFC5230 explains the conditions necessary for the Sieve Vacation extension to trigger a response. This says: "Vacation" MUST NOT respond to a message unless the recipient user's email address is in a "To", "Cc", "Bcc", "Resent-To", "Resent-Cc", or "Resent-Bcc" line of the original message. So your scenario 4 happens when the sender is only in the envelope, and not in the headers. For example: this transaction will get a response because the mailbox address is in the To: header ehlo there.com mail from: <dude(a)there.com> rcpt to: <user(a)domain.tld> << envelope recipient, mailsystem routes with this information data To: "Some User" <user(a)domain.tld> << header recipient must be correlated for Sieve Vacation to send a response From: "Dude" <dude(a)there.com> Subject: message Hi there . This transaction will not get a response, and will trigger the "discarding vacation response for message implicitly delivered to <user(a)domain.tld> " log: ehlo there.com mail from: <dude(a)there.com> rcpt to: <user(a)domain.tld> data Subject: message Hi there .

[Dovecot] Dovecot 2.0 b13e01d82083
by Renaud Allard 18 Mar '10

Hello, I was trying to compile Dovecot 2.0 b13e01d82083, and I found this when doing make: Making all in lib test -f UnicodeData.txt || wget http://www.unicode.org/Public/UNIDATA/UnicodeData.txt /bin/sh: wget: not found I think it's probably not the best idea to assume everyone has wget installed. Perhaps it is installed by default on linux, but probably not on all other platforms. Why not just include the UnicodeData.txt file? Best Regards

[Dovecot] .mailboxlist location
by Dave Brenner 18 Mar '10

18 Mar '10

Greetings. On our 1.2.9 setup, we are finding that .mailboxlist (we recompiled to use this name rather than .subscriptions) ends up in the user's ~/mail folder. We'd like this file to be stored in ~/ instead. Is this possible without changing namespaces (for UW compatibility) and/or userdb mail location?

[Dovecot] v1.2.11 released
by Timo Sirainen 18 Mar '10

18 Mar '10

http://dovecot.org/releases/1.2/dovecot-1.2.11.tar.gz http://dovecot.org/releases/1.2/dovecot-1.2.11.tar.gz.sig mbox users really should upgrade, because by sending a message with a huge header you could basically cause a DoS (this problem exists only with v1.2.x, not with v1.0 or v1.1). - mbox: Message header reading was unnecessarily slow. Fetching a huge header could have resulted in Dovecot eating a lot of CPU. Also searching messages was much slower than necessary. - mbox, dbox, cydir: Mail root directory was created with 0770 permissions, instead of 0700. - maildir: Reading uidlist could have ended up in an infinite loop. - IMAP IDLE: v1.2.7+ caused extra load by checking changes every 0.5 seconds after a change had occurred in mailbox

Re: [Dovecot] I stream read - stale NFS file handle (reboot of server)
by Damon Atkins 18 Mar '10

18 Mar '10

In the old days NFS Shared Path had a static handle (ie a number), normal based on some number pulled out of the file system/inode. To fix (well work around) a security issue, for about 10+ years now, when a NFS server reboots, it generates a new random handle for the NFS Share. (sever may generate a new random handle per mount request) The NFS Stale Handle happens when the client is still using the old NFS handle, the only fix is a remount Some NFSv3 server let you fix the handle id for NFS share so it does not change over reboots. (this is how NFS clustering works, sometimes you need to install cluster software if the exportfs/share command does not let you hard code the fsid by hand. The other option is to use NFSv4 which is design to handle reboots by servers.

[Dovecot] Testing EXTERNAL AUTHENTICATION
by Stephen Feyrer 17 Mar '10

17 Mar '10

Hi. I'm trying to test EXTERNAL AUTHENTICATION in Dovecot. To do this I first configured Thunderbird and Opera to use my server, neither of them were successful. As a result I contacted both organisations to enquire if they supported EXTERNAL AUTHENTICATION in their products. Thunderbird responded and said yes. However, on closer inspection my contact at Thunderbird identified that support for EXTERNAL AUTHENTICATION was poor at best and then only in SMTP. From that point on, my contact has been trying to implement support in Thunderbird. I've also try to test using openssl s_client which is detailed below. As far as I can tell my problems appear after the authentication. I don't know what the problem is only that there is one.

[Dovecot] qmail-secretary plugin for dovecot deliver
by Rajkumar S 17 Mar '10

17 Mar '10

Hi, I have been using qmail-ldap for quite some time and now moved to postfix/dovecot. One feature that I miss is that provided by qmail-secretary. qmail-secretary basically is a mail list manager with following features: 1 no limit, just explode to all members 2 members only, as the name says; only members are allowed (based on envelope sender, so not very secure, everybody can fake that) 3 sender confirm, sender has to confirm submission and return address like DJBs qmail-secretary 4 moderated, moderator(s) have to accept every message; there are DN and RFC822 moderators All configuration (name, members, moderated etc...) are taken from LDAP. I had gone through the code and from what I understand for each 4 delivery types it works as follows: 1. Just deliver to all recipients (say, inject it via sendmail). 2. verify if envelope sender is in allowed list and proceed as above. 3. 1. create a random hash 2. save the mail in new/ with hash as filename 3. create a new mail with listname-confirm-hash(a)domain.com and send 4. If that mail comes back, deliver the mail to all recipients. 4. 1. as above but using listname-approve-hash and list-name-reject-hash 2. move the msg to cur/ 3. if appropriate reply comes retrieve the mail from cur/ and send to all recipient. qmail-secretary is invoked by qmail-local and thus this is a nice candidate for a deliver plugin. Before I start coding I just want to check if there is any gotchas that I am missing? I assume all these operations can be performed as a deliver plugin and that deliver plugin is the correct place for such functionality. It goes without saying that I would be contributing this plugin back to dovecot. with regards, raj

Re: [Dovecot] [xmail] XMail + Dovecot
by Sabahattin Gucukoglu 17 Mar '10

What, exactly, is the problem? How do you want Dovecot and XMail to work together? I am setting up Dovecot to read from standard Maildirs in user home directories, because I am using a separate delivery agent (TMDA but would work for maildrop, Dovecot's deliver program and others) to deliver mails using mailproc.tab. So, even while XMail runs as root, Dovecot need not and there is no problem getting it to work just like with other MTAs. XMail can't help with delivery to Maildir because it runs as root, and unless you mess about with packet filters to non-root it you'll still end up using for instance XACLs to allow Dovecot to read the mails. For authentication of XMail to Dovecot you would have to write external authentication helpers that use Dovecot's protocol. Or, you can use checkpassword or PAM-POP3 or something else to try getting Dovecot to authenticate against the active XMail list of users. Or you can just do what I do, maintain two databases and keep them in sync. Cheers, Sabahattin

[Dovecot] Design: Asynchronous I/O for single/multi-dbox
by Timo Sirainen 17 Mar '10

17 Mar '10

The long term plan is to get all of Dovecot disk I/O asynchronous. The first step to that direction would be to make dbox/mdbox I/O asynchronous. This might also allow mbox/maildir to become partially asynchronous. http://www.dovecot.org/list/dovecot/2009-December/045481.html already started describing how the lib-storage API could be changed to support high-latency storages. Adding support for all of the paralellism would be nice, but probably not necessary as the first step. Then again, the API changes are necessary, so the parallelism optimizations probably aren't a huge task on top of that. Besides the API changes described in the above link, another change that's necessary is to add mail_get_nonblocking_stream(). The returned stream can return EAGAIN whenever it would need to block. Whenever sending message data to client, this stream would have to be used. It would also be used internally by all of message parsing/searching code. Luckily all of that already supports nonblocking input or can be easily modified to support it. Below are some thoughts how to go forward with this. I originally thought about writing a more specific plan, but I think this is good enough now to start coding. The target Dovecot version is v2.1, not v2.0. Filesystem API ============== The idea is to first abstract out all POSIX filesystem accessing in dbox/mdbox code. Non-blocking I/O works pretty nicely for socket I/O, so I thought I'd use a similar API for disk I/O as well: handle = open(path, mode) - this function can't fail. it's executed asynchronously. - mode=read-only: no writing to file - mode=append: appending to file is allowed handle = create(path, mode, permissions) - this function can't fail. it's executed asynchronously. - mode=fail-if-exists: commit() fails if file already exists - mode=replace-if-exists: commit() replaces file if it already exists - permissions: i'm not entirely sure how this works yet. but it should contain mode and gid in some format set_input_callback(handle, callback, context) set_output_callback(handle, callback, context) - call the callback when more data can be read/written ret = pread(handle, buf, size, offset) - just like pread(), but can fail with EAGAIN if there are no bytes already buffered. so the idea is that the backend implementation would buffer/readahead data, which would be returned by this call. this would require memcpy()ing all data, but it might get too complex/fragile if it was asynchronously written to given buffer. ret = write(handle, buf, size) - append data to given file and return how many bytes were actually added to write buffer. works in a similar way than writing to socket. data can only be appended to files, there is no support for overwriting data. - no writes will be visible to reads until commit() is called ret = commit(handle, [filename]) - commit all previous writes to disk. either returns success/EAGAIN. - if filename is given and a new file is being created, the filename is changed to the given one instead of using the original path's filename. this is needed because e.g. mdbox saving can write many temp files in a single transaction and only at commit stage it locks the index files and knows what the filenames will be. rollback(handle) - rollback all previous writes. close(handle) - if file was created and not committed, the temp file will be deleted - does implicit rollback ret = try_lock(handle) - this isn't an asynchronous operation! it assumes that locking state is kept in memory, so that the operation will be fast. if backend doesn't support locking or it's slow, single-dbox should be used (instead of multi-dbox), because it doesn't need locking. - returns success or "already locked" - only exclusive locking is possible Async IO streams ================ Async input streams are created with FS API handle, so it's possible to start reading from them before the file has even been open()ed. The callers must be aware of this and realize that read() can fail with ENOENT, etc. Async input streams' read() would work exactly as file_istream works for non-blocking sockets: It would return data that is already buffered in memory. If there's nothing, it returns EAGAIN. The FS API's set_input_callback() can be used to set a callback function that is called whenever there's more data available in the buffer. Async output streams also work the same as non-blocking file_ostreams: write() returns the number of bytes added to buffer. When buffer becomes full, it starts returning EAGAIN. The ostream handles flushing internally the same way as file_ostreams does, although instead of using io_add(IO_WRITE) it uses FS API's set_output_callback(). If callers need to know when more data can be written or when all of the data has been written, it can override the ostream's flush_callback, just like with file_ostreams. Async IO for FS API backend =========================== So now that all of the APIs have been designed, all that's needed to do is to write a simple FS API implementation using kernel's async IO API, right? Wrong. There is no usable async IO API in Linux, and probably nowhere else either: * POSIX AIO isn't supported by Linux kernel. And even if it was, it only supports async reads/writes, not async open(). * Linux kernel has its own native AIO implementation! ..But it only works with direct IO, which makes it pretty much useless for almost everyone. There have been many different attempts to get buffered AIO support to Linux, but all of them have failed. So for now the only practical way is to implement it with threads. There are several libraries that could make this easier.. But all of them enable (and require) full thread safety for libc calls. I don't really like that. Dovecot isn't using threads, I shouldn't pay the penalty of using extra locking when it's really not necessary. So I was thinking about doing the async IO in two ways: 1) For Linux/x86/x86-64 (and maybe others) implement a version that creates threads with clone() and uses lockless queues for communicating between the async io worker threads. The threads won't use malloc() or any other unsafe calls, so this should be pretty nice. 2) Fallback version that uses pthreads with mutexes. Is 2) going to be noticeably slower than 1)? Probably not.. In both cases there is also the problem of how many worker threads to create. I've really no idea, kernel would be so much better in deciding that.. I guess that also depends on how many processes Dovecot is configured to run on (and how busy they are at the moment). Maybe it could be just a globally configurable number of threads/process, defaulting to something like 10. dbox changes ============ Most of the dbox code shouldn't be too difficult to change to using the FS API. The one exception is writing messages. Currently the format looks like: <dbox header magic (2 bytes)> <dbox message header, which contains message size><lf> <message> <dbox metadata magic (2 bytes)><lf> <dbox metadata> <lf> The problem is that the message size isn't always known before the message is written. So currently the code just pwrite()s the size afterwards, but this is no longer possible with the new FS API. One possibility would be to buffer the message in memory, but that could waste a lot of memory since messages can be large. So the only good solution is to change the dbox file format to contain the message size after the message. At the same time the dbox format could be cleaned up from old broken ideas as well. The reading code could support the old version format as well, because reading isn't a problem. The new dbox format could look like: <dbox header magic (2 bytes)> <dbox unique separator (random 16 bytes or so)><lf> <message> <dbox metadata magic (2 bytes)> <dbox unique separator, same as above><message size><lf> <dbox metadata, last item being metadata size> <lf> The unique separator exists there primarily for fixing corrupted dbox storage, so it can (quite) reliably recognize where a message ends. Multi-dbox's indexes contain already the message offset + size of (message+metadata), i.e. offset+size = offset of next message. The size is primarily used to figure out if more data can be appended to the file (so it won't grow too large). This size could just be changed to become message's size and the check just changed to assume metadata size would be e.g. 512 bytes. It won't really matter in practise. So then the reading code could get the message's size from the index. Single-dbox doesn't have such index. There are two ways to solve the problem there (both actually would work for multi-dbox too): 1) Metadata block can be found by reading backwards from end of file. For example read the last 512 bytes of the file and find the metadata magic block. Get the message's size from there. 2) Create an istream that simply reads until it reaches dbox metadata magic and unique separator. And to be absolutely sure it reached the correct end of message, it can also check that the rest of the data in the stream contains only a valid metadata block.

[Dovecot] how configure quotas with dovecot and mysql databases
by Wilberth Pérez 17 Mar '10

17 Mar '10

some one knows, how to configure quotas with dovecot and mysql databases ? my dovecot was compiled with: CPPFLAGS=-I/opt/mysql/include/mysql LDFLAGS=-L/opt/mysql/lib/mysql ./ configure --with-sql --with-mysql and my dovecot.conf and dovecot-sql.conf have the following configurations: =========== dovecot.conf =========== protocol imap { listen = *:143 mail_plugins = quota imap_quota } protocol pop3 { listen = *:110 mail_plugins = quota } plugin { quota = maildir:storage=30M quota_rule = *:storage=30M quota_warning = storage=95%% /usr/local/bin/quota-warning.sh 95 quota_warning2 = storage=80%% /usr/local/bin/quota-warning.sh 80 } ============ dovecot-sql.conf ============ driver = mysql connect = host=localhost dbname=mail user=mail password=mail user_query = SELECT 1 AS gid, concat('maildir:storage= ', quota_kb) AS quota FROM users WHERE user = 'testuser'; I test my configuration and don't show errors , however, dovecot never show me my quota configuration. I will be omitting something ?

[Dovecot] Dovecot 2.0beta3: Auth master process is now running as default_internal_user
by Thomas Leuxner 16 Mar '10

16 Mar '10

Hi, with 'changeset 10910' the Auth master process is running as 'default_internal_user' now (dovecot). This requires permissions tuning for 'passwd-files' at least, while other plugins would run in a different user context, 'vmail' in my setup. I see that this may be safer, just wondering how to streamline the config: [20:27] root spectre:/var/vmail/conf.d# l drwxr-x--- 4 dovecot vmail 4096 2010-03-14 17:40 leuxner.net [20:27] root spectre:/var/vmail/conf.d# l leuxner.net/ drwx------ 2 vmail vmail 4096 2010-03-14 13:09 acls -r-------- 1 dovecot vmail 125 2010-02-07 13:08 passwd drwx------ 2 vmail vmail 4096 2010-03-14 12:13 sieve [20:27] root spectre:/var/vmail/conf.d# cat leuxner.net/passwd tlx@leuxner.net:{SSHA}xxxx:5000:5000::/var/vmail/leuxner.net/tlx::userdb_quota_rule=*:storage=5G […] Regards Thomas

[Dovecot] ACL problem
by SZÉKELYI Szabolcs 16 Mar '10

16 Mar '10

Hey, I seem to have a problem with ACLs. I'm trying to use them on shared folders those work fine without it. But as soon as I enable the plugin and create the dovecot-acl files, they disappear. I used strace to see if there's a problem with file permissions, but it looks like Dovecot doesn't even attempt to access the dovecot-acl file in the maildir, only the dovecot-acl-list files. However, it does look for dovecot-acl files in users' home directories. Maybe the ACL plugin is enabled only for the private mailboxes, not for the public ones, but I want right the opposite. How can I achieve it? Please find my dovecot config below.

[Dovecot] Authentication userdb file / configuration help - newbie question...
by Zilon X 16 Mar '10

16 Mar '10

Hi All, I need to configure Dovecot with a XMail server ( www.xmailserver.org ) - this server uses a userdb file with the following format: "domain"[TAB]"account"[TAB]"encrypted-passwd"[TAB]"account-id"[TAB]"account-dir"[TAB]"account-type"[NEWLINE] How can authenticate Dovecot against this userdb file? Was anyone doing that? Maybe, can I authenticate Dovecot using SMTP Auth? Thank you for any help!

[Dovecot] Dovecot 2.0b3: mdbox with incorrect ACL file permissions crashes
by Thomas Leuxner 16 Mar '10

16 Mar '10

Hi, played around with 'mdbox' format some more. Converted my personal mailbox with latest Dovecot and dsync from HG: dsync convert -u login(a)yourdomain.com mdbox:~/mdbox One thing I noticed is, that dsync does not take care of existing 'dovecot-acl' files, which it should migrate/copy from my point of view, but simply skips them. Anyway I copied over the ACLs manually and forgot to set the rights accordingly. So the files were owned by 'root:vmail' instead of 'vmail:vmail' in my setup. Voilà Dovecot crashed, where it should really throw a warning or ignore the owner and work with the group permissions: Mar 2 19:27:52 spectre dovecot: imap(tlx(a)leuxner.net): acl vfile: file /var/vmail/conf.d/leuxner.net/acls/Support/Serverloft not found Mar 2 19:27:52 spectre dovecot: imap(tlx(a)leuxner.net): acl vfile: no access to file /var/vmail/leuxner.net/tlx/mdbox/mailboxes/Support/Serverloft/dbox-Mails/dovecot-acl Mar 2 19:27:52 spectre dovecot: imap(tlx(a)leuxner.net): Panic: file acl-cache.c: line 295 (acl_cache_update_rights): assertion failed: (obj_cache->my_current_rights != &negative_cache_entry) Mar 2 19:27:52 spectre dovecot: imap(tlx(a)leuxner.net): Raw backtrace: /usr/lib/dovecot/libdovecot.so.0 [0x7f4d8595ffb2] -> /usr/lib/dovecot/libdovecot.so.0 [0x7f4d8596001a] -> /usr/lib/dovecot/libdovecot.so.0 (i_error+0) [0x7f4d859603c3] -> /usr/lib/dovecot/modules/lib01_acl_plugin.so [0x7f4d84da690b] -> /usr/lib/dovecot/modules/lib01_acl_plugin.so [0x7f4d84da4249] -> /usr/lib/dovecot/modules/lib01_acl_plugin.so [0 x7f4d84da4572] -> /usr/lib/dovecot/modules/lib01_acl_plugin.so [0x7f4d84da472e] -> /usr/lib/dovecot/modules/lib01_acl_plugin.so [0x7f4d84da2aba] -> /usr/lib/dovecot/modules/lib01_acl_plugin.so(acl_object_get_m y_rights+0x65) [0x7f4d84da2b85] -> /usr/lib/dovecot/modules/lib01_acl_plugin.so [0x7f4d84da8fd9] -> dovecot/imap [tlx(a)leuxner.net 84.58.106.99 STATUS](client_find_namespace+0x17f) [0x41149f] -> dovecot/imap [t lx(a)leuxner.net 84.58.106.99 STATUS](cmd_status+0xfc) [0x40dc2c] -> dovecot/imap [tlx(a)leuxner.net 84.58.106.99 STATUS] [0x40f9bc] -> dovecot/imap [tlx(a)leuxner.net 84.58.106.99 STATUS] [0x40fa6d] -> dovecot/imap [tlx(a)leuxner.net 84.58.106.99 STATUS](client_handle_input+0x45) [0x40fbe5] -> dovecot/imap [tlx(a)leuxner.net 84.58.106.99 STATUS](client_input+0x62) [0x410622] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handl er_run+0xcb) [0x7f4d8596abab] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x18) [0x7f4d85969d28] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f4d85959eb3] -> dovecot/imap [tlx(a)leuxner.n et 84.58.106.99 STATUS](main+0x191) [0x418661] -> /lib/libc.so.6(__libc_start_main+0xe6) [0x7f4d851e71a6] -> dovecot/imap [tlx(a)leuxner.net 84.58.106.99 STATUS] [0x4084e9] Mar 2 19:27:52 spectre dovecot: master: service(imap): child 30281 killed with signal 6 (core dumps disabled) Regards Thomas

[Dovecot] Shared folders
by Неворотин Вадим 16 Mar '10

16 Mar '10

I need to create a shared folder (mailbox for group mailing list) with access of several accounts to it. But all peoples with access to this mailbox should be able to work with this folder absolutely in the same way, as with local mailbox. Each user should be able to delete emails and mark it as readed. But this changes must be only for one user, not for others. For example user1 and user2 have access to folder Trades. There is a new incoming mail. User1 read it and delete. But in user2's client this mail must be not readed and not deleted. So there should be only one copy of a email (in group mailbox), but state (unreaded|readed|deleted) of this email shoud be different for each user. Can I do this with dovecot? Yes, I know that I can send a copy of group letter to each user's mailbox, but unfortunately I has a lot of groups and very big letters, so I can't duplicate each letter to many mailboxes. The purpose is to story only one instance of each letter, but to allow users to work with it like with their own letters. Now I use Maildir++ mailboxes.

[Dovecot] Quota plugin and SQL
by David 16 Mar '10

16 Mar '10

I have read through http://wiki.dovecot.org/Quota/Dict, which suggests a database schema for using quota. For 1.2, this includes a username, bytes and messages. Is there any way to modify the queries used to split out username into localpart and domain? This would enable me to put the current quota information in my main mailbox table and display it to users in my admin interface. Or possibly it should be in a separate table for a reason, and I should be look there for the values? Thanks, David

[Dovecot] extraneous mail folder created
by John Moorhouse 16 Mar '10

16 Mar '10

I'm trying to set up dovecot on a Fedora box for about 5 users, I have a raid 5 array that is used for home folders etc mounted on /home, and I've created a directory /home/mail, which I have used a sym link to map /var/mail to. I've created folders for each of the users with relevant permissions and edited the dovecote config with:- namespace private { separator = / prefix = "#dbox/" location = dbox:~/mail:INBOX=/var/mail/%u inbox = yes hidden = yes list = no # for v1.1+ } namespace private { separator = / prefix = location = dbox:/var/mail/%u/mail } This all seems to work with the exception that when a imap client attaches to dovecot an empty folder called 'mail' is created in the users home directory. so for client jenni, whist all her emails etc are stored in /home/mail/jenni/ for INBOX and /home/mail/jenni/mail/ for folders etc, an empty folder is created as /home/jenni/mail/ Any help appreciated John

[Dovecot] IMAP proxy configuration
by Leonardo Rodrigues 16 Mar '10

16 Mar '10

i know dovecot can act as IMAP and POP3 proxy ..... but i'm having a hard time configuring it. Actually i'm using a simple dovecot configuration with virtual users stored on MySQL. My dovecot-sql.conf is pretty simple: [root@correio dovecot]# cat dovecot-sql.conf driver = mysql connect = host=localhost dbname=DATABASE user=USERNAME password=PASSWORD default_pass_scheme = PLAIN # Get the mailbox user_query = select '/var/spool/mail/%u' as home, 'maildir:/var/spool/mail/%u' as mail, 8 as uid, 12 as gid, concat('*:storage=', quota) as quota_rule, 'Trash:storage=100M' as quota_rule2 from emails where endereco = '%u' and ativa = '1' # Get the password password_query = select endereco as user, password, '/var/spool/mail/%u' as userdb_home, 'maildir:/var/spool/mail/%u' as userdb_mail, 8 as userdb_uid, 12 as userdb_gid, concat('*:storage=', quota) as userdb_quota_rule, 'Trash:storage=100M' as userdb_quota_rule2 from emails where endereco = '%u' and ativa = '1' [root@correio dovecot]# i've read several docs about configuring proxy on dovecot but all of them says about proxying specific users .... i'm interested on proxying some domains. I couldnt find a way to configure that nor some howto similar to that. could anyone point me some documentation on configuring dovecot as IMAP/POP3 proxy for a full domain and not specific users ? Ideally i would have a list of domains that should be proxied to somewhere else and all the other domains would be threated locally.

[Dovecot] dovecot-2.0.beta3 does not create dovecot/login directory
by Jürgen Bereuter 16 Mar '10

16 Mar '10

Hello, i build the beta3 of dovecot 2.0 on Opensolaris (SunOS sol 5.11 snv_134 i86pc i386), restarted and dovecot logs the following error. I created the directory path /var/run/dovecot/login and voila, imap is starting up without any problems. But as soon as i reboot the PC (it is only a pseudo private server), the new directory gets deleted (as expected and planed, as fa as i know), but not to be (re)created. Not a big problem, but i think it is worth to mention it. Perhaps i am wrong and messed something completely up, in that case i would be glad to receive a clue. Thanks, bye, jürgen Permissions of /var/run/dovecot are drwxr-xr-x 4 root root 573 Mär 15 21:03 dovecot Mar 15 20:12:54 imap-login: Info: Login: user=<xxxxxx>, method=PLAIN, rip=xx.xx.xx.xx, lip=10.0.0.5 Mar 15 20:25:22 imap(jub): Warning: Killed with signal 15 (by pid=846 uid=0 code=kill) Mar 15 20:25:22 imap(jub): Info: Server shutting down. bytes=31/428 Mar 15 20:25:22 imap(jub): Warning: Killed with signal 15 (by pid=846 uid=0 code=kill) Mar 15 20:25:22 imap(jub): Info: Server shutting down. bytes=1071/3075 Mar 15 20:25:22 imap(jub): Warning: Killed with signal 15 (by pid=846 uid=0 code=kill) Mar 15 20:25:22 imap(jub): Info: Server shutting down. bytes=504/1548 Mar 15 20:25:22 imap(jub): Warning: Killed with signal 15 (by pid=846 uid=0 code=kill) Mar 15 20:25:22 imap(jub): Info: Server shutting down. bytes=1176/1090254 Mar 15 20:25:22 log: Warning: Killed with signal 15 (by pid=846 uid=0 code=kill) Mar 15 20:25:22 master: Warning: Killed with signal 15 (by pid=846 uid=0 code=kill) Mar 15 20:26:48 master: Error: opendir(/var/run/dovecot//login) failed: No such file or directory Mar 15 20:26:51 master: Error: bind(/var/run/dovecot//login/ssl-params) failed: No such file or directory Mar 15 20:26:51 master: Error: bind(/var/run/dovecot//login/imap) failed: No such file or directory Mar 15 20:26:51 master: Error: bind(/var/run/dovecot//login/dns-client) failed: No such file or directory Mar 15 20:26:51 master: Error: bind(/var/run/dovecot//login/auth) failed: No such file or directory Mar 15 20:26:51 master: Fatal: Failed to start listeners Mar 15 20:26:51 master: Error: opendir(/var/run/dovecot//login) failed: No such file or directory Mar 15 20:26:51 master: Error: bind(/var/run/dovecot//login/ssl-params) failed: No such file or directory Mar 15 20:26:51 master: Error: bind(/var/run/dovecot//login/imap) failed: No such file or directory Mar 15 20:26:51 master: Error: bind(/var/run/dovecot//login/dns-client) failed: No such file or directory Mar 15 20:26:51 master: Error: bind(/var/run/dovecot//login/auth) failed: No such file or directory Mar 15 20:26:51 master: Fatal: Failed to start listeners Mar 15 20:26:52 master: Error: opendir(/var/run/dovecot//login) failed: No such file or directory Mar 15 20:26:52 master: Error: bind(/var/run/dovecot//login/ssl-params) failed: No such file or directory Mar 15 20:26:52 master: Error: bind(/var/run/dovecot//login/imap) failed: No such file or directory Mar 15 20:26:52 master: Error: bind(/var/run/dovecot//login/dns-client) failed: No such file or directory Mar 15 20:26:52 master: Error: bind(/var/run/dovecot//login/auth) failed: No such file or directory Mar 15 20:26:52 master: Fatal: Failed to start listeners

[Dovecot] Courier to dovecot migrations
by Daniel Grilo 16 Mar '10

16 Mar '10

Dear All, I saw some topics discussed in forums about this, but none with my problems :( Currently we have a mailserver postfix with courier-imap-4.1.1, and courier-pop3 and courier-authlib. Our Maildir's are written in the users home directory (ex: ~/Maildir) I'm now migrating the mailserver to other cluster and installing with dovecot. We're also moving the Maildir's to other directory (ex: /opt/mailboxes/%u) I've ran your perl script courier-dovecot-migrate-1.0.pl which worked just great (as far as I can tell from the OK messages) .. but when configuring my mail client for this account I get the following: Mar 16 09:49:27 magenta dovecot: auth(default): master out: USER 69 scanner system_user=scanner uid=734 gid=100 home=/home/scanner Mar 16 09:49:27 magenta dovecot: imap-login: Login: user=<scanner>, method=PLAIN, rip=::ffff:192.168.1.210, lip=::ffff:192.168.1.110 Mar 16 09:49:27 magenta dovecot: IMAP(scanner): Effective uid=734, gid=100, home=/home/scanner Mar 16 09:49:27 magenta dovecot: IMAP(scanner): maildir: data=/opt/mailboxes/scanner Mar 16 09:49:27 magenta dovecot: IMAP(scanner): maildir: root=/opt/mailboxes/scanner, index=/opt/mailboxes/scanner, control=, inbox= Mar 16 09:49:27 magenta dovecot: IMAP(scanner): stat(/opt/mailboxes/scanner/cur) failed: Permission denied Mar 16 09:49:27 magenta dovecot: IMAP(scanner): stat(/opt/mailboxes/scanner/cur) failed: Permission denied [root@magenta ~]# ls -la /opt/mailboxes/ total 36 drwxrwx--- 4 root dovecot 4096 Mar 15 11:49 . drwxr-xr-x 6 root dovecot 4096 Mar 9 2009 .. drwxrwx--- 2 root root 16384 Feb 10 15:55 lost+found drwx------ 9 scanner users 4096 Mar 15 11:56 scanner The second problem is between postfix / dovecot..

[Dovecot] public folders grayed out
by Harald Dunkel 16 Mar '10

16 Mar '10

Hi folks, I have configured a public folder as described on the Wiki (more or less; see below), but in TB3 I see the "Public" folder grayed out. I cannot subscribe. Toggling the subscriptions flag doesn't help. What did I miss here? Any helpful comment would be highly appreciated. If this is a TB3 problem: Which MUA would you suggest?

[Dovecot] Fatal: open() failed for /var/run/dovecot/login: Permission denied
by Andy Yen 15 Mar '10

15 Mar '10

I keep getting this message when I try to start dovecot using the -F option. Fatal: open() failed for /var/run/dovecot/login: Permission denied Checking /var/run/dovecot/login folder permissions does not seem to indicate anything wrong as root has all the permissions it needs. If I am not mistaken, dovecot can run as root while in the login directory correct? When I try to start the dovecot service, it fails with the message: dovecot dead but subsys locked. Can anybody help me resolve this issue? I am running RHEL5.4. Thanks in advance.

[Dovecot] Extra Imap processes
by Dominique St-Amand 15 Mar '10

15 Mar '10

Hello fellow dovecot users! I have a question for you guys. I have a server running dovecot/exim and I allow both pop/pops and imap/imaps. When I look at the running processes, I see a lot of imap processes that look like the following: imap [user(a)domain.tld USER_IP] Sometimes, there are duplicates imap [user(a)domain.tld USER_IP] processes. I was wondering, how come those processes don't quit and stick around in the system? Should they quit after the user issued the disconnect command from its mail client? Also, is there any way to actually make them to quit or should I make a shell script that runs at a certain period of time and actually kill those processes? Thanks

[Dovecot] Status update
by Timo Sirainen 14 Mar '10

14 Mar '10

Looks like I'm pretty badly lagged behind emails in mailing list and in my INBOX. I should read and do something about maybe 150 messages. The good thing at least is that v2.0 is getting closer. Only 3 larger things left besides bug fixing: 1. config handling is too slow 2. I just noticed auth cache is only for passdb. it really should be changed to cache userdb too. 3. fts-solr should optionally use mailbox GUIDs instead of mailbox names And 2 and 3 are actually old problems..

[Dovecot] Bug in driver-mysql.c + fix
by Alain Williams 13 Mar '10

13 Mar '10

I tried to use MySQL stored procedures from dovecot: password_query = CALL user_pass_check('%n', '%d', '%w') user_query = CALL user_info('%n', '%d') This failed with the message: User query failed: PROCEDURE imap.user_info can't return a result set in the given context The root of this problem is that mysql_real_connect() needs to be called with option CLIENT_MULTI_RESULTS and mysql_next_result() called to retrieve extra results (that will not exist in the way that we use it). I attach a patch that fixes this problem -- the patch is against dovecot-1.2.10. This works for me ... but could probably do with testing by other people. BTW: I got the same problem with exim this morning, wrote a patch that has now been accepted. The dovecot patch is similar. I am looking to use mysql procedures, there are some interesting things that can be done. Two suggestions that I have will help with this: 1) There be variable (say) %o - this be the obscured password, ie what password_query returns. 2) that dovecot look for either ''password_query'' as above, or ''password_check''. password_check would NOT return a password, but would be given %o and determine itself if the password is correct. It would return the other values (user, userdb_home, ...) and auth_result that would encode success/retry/fail (0, 1, 2 - or maybe more structured [**]) and auth_reason some human readable reason. The ''nologin'' value encodes some of this. The motivation for this is that my stored procedure will record the number of successive login failures and lock the account after 3 of them. It would also be possible to do time based restrictions & the such. Also: by passing %o the password is not sent in plain to the database server - which will increase security. I will publish my stored procedures when done. Regards [**] eg taking ideas from the HTTP codes: 200 - OK 300 5 - try again in 5 minutes 301 2 9 - try again on tuesday at 9am 400 - Login forbidden, no reason given 401 - bad username and/or password 402 - account locked administratively 403 - too many failed login attempts 500 - authentication system error The above would allow a native language version of auth_reason to be produced -- Alain Williams Linux/GNU Consultant - Mail systems, Web sites, Networking, Programmer, IT Lecturer. +44 (0) 787 668 0256 http://www.phcomp.co.uk/ Parliament Hill Computers Ltd.

[Dovecot] Plugin like zlib
by Alex Baule 13 Mar '10

13 Mar '10

Hi everyone. I rebuild a plugin, based on zlib plugin. The changes between this plugin and zlib, is the zlib stuffs is replaced by open, read, lseek, close. With "plain-text" files, its works ok. So, my file is encrypt, and the result from decrypt file is different from fread. Like zlib, i read from fread the size variable, but the value added in seek_offset and pos is the result from decrypt, and it can be dfferent from fread. Like zlib, my file size is different from email. In zlib the file is smaller than the email. In my file, the file is bigger than the email. OK, lets go to the problem now. when the email arrives in the new folder, by imap, the stat (read my file by "while (i_stream_emexis_read(stream) > 0)" like zlib) and the seek works fine....the email is readed and the final stat size is the decrypted size of my email (smaller than original file). When I receive the email, clicking in "Send/Receive", The read function is aborted because the size to read (like zlib) is negative. I put some debug in my plugin, and print some stuffs about the functions. Email decryt size = 49556 Email encrypt size = 49568 Attachements: mail-arrived, is when the email arrives, and it's ok the read. mail-receive, is when the email is received, and have the error. maillog is the /var/log/mail The bigger difference from zlib is the i_stream_zlib_read part.... do { ret = read(zstream->fd ,crypttext, size); fprintf(zstream->debug,"DENTRO DA READ RET = %d -- ERRNO = %d -- STR = |%s|\n", ret, errno, strerror(errno)); if(ret > 0){ EVP_DecryptUpdate(&ctx, plaintext, &plain_len, crypttext, ret); memcpy(stream->w_buffer + stream->pos , plaintext, plain_len); bzero (plaintext, DEFAULT_MAX_BUFFER_SIZE); EVP_DecryptFinal(&ctx, plaintext, &plain_len_final); memcpy(stream->w_buffer + stream->pos + plain_len , plaintext, plain_len_final); } } while (ret < 0 && errno == EINTR && stream->istream.blocking); *retc *= plain_len + plain_len_final; if (ret == 0 ) { /* EOF */ stream->istream.eof = TRUE; return -1; } if (ret < 0) { if (errno == EAGAIN) { i_assert(!stream->istream.blocking); ret = 0; // } else { // i_assert(errno != 0); // stream->istream.stream_errno = errno; // return -1; } } fprintf(zstream->debug,"READ RET = %d -- ERRNO = %d -- STR = |%s|\n", ret, errno, strerror(errno)); fprintf(zstream->debug,"stream->pos = %d -- zstream->seek_offset = %d\n", stream->pos, zstream->seek_offset); zstream->seek_offset += *retc*; stream->pos += *retc*; i_assert(ret > 0); fprintf(zstream->debug,"READ RET DECRYPT = %d -- stream->pos = %d -- zstream->seek_offset = %d\n", ret, stream->pos, zstream->seek_offset); fprintf(zstream->debug,"********************** FINISH READ *********************\n"); fflush(zstream->debug); return *retc;* The* retc* is the result from decrypt. In mail-receive file (line 38), there is the error, at some point along the read/send email, the stream->pos (its returned by i_stream_compress, with stream->pos -= stream->skip) is changed out from context and the size to read is negative, but i don't understand why. Someone can help me find out what happens ?

[Dovecot] Sendmail / Dovecot Config
by John Moorhouse 13 Mar '10

13 Mar '10

I'm trying to set up dovecot on a Fedora box for about 5 users, I have a raid 5 array that is used for home folders etc mounted on /home, and I've created a directory /home/mail, which I have used a sym link to map /var/mail to. I've created folders for each of the users with relevant permissions and edited the dovecote config with:- namespace private { separator = / prefix = "#dbox/" location = dbox:~/mail:INBOX=/var/mail/%u inbox = yes hidden = yes list = no # for v1.1+ } namespace private { separator = / prefix = location = dbox:/var/mail/%u/mail } I was hoping that this would create a inbox in the root of each users folder in the mail directory and a sub folder to hold any user created folders. This all seems to work as I can create folders, copy emails to them r-arrange the folders etc as I want via a mail client using imap on 143. My only problem is that I have also configured send mail as best as I know to listen on port 25 as an SMPT client but any emails sent to it to one of the email addresses are saved by sendmail to /var/spool/mail/username and not picked up by dovecot Thanks John

[Dovecot] Emails Disappearing -- Mystery

12 Mar '10

I got a case that I haven't been able to resolve. I hope somebody can give me some hints. One of our users is reporting emails disappearing in front of his eyes, (Right ... emails filters at the client side ....) Server does not have global sieve filter enabled (no file present), even though this configuration is present: sieve_global_path=/vmail/globalsieverc User does not have any sieve scripts enabled at the server side. Ok, 1) The user shuts down his apple mail software, his Iphone, and the Web interface: 2010-03-11 15:52:57 IMAP(my_user(a)mydomain.com): Info: Connection closed bytes=2188/6499 2010-03-11 15:52:57 IMAP(my_user(a)mydomain.com): Info: Connection closed bytes=3887/7336 2010-03-11 15:52:57 IMAP(my_user(a)mydomain.com): Info: Connection closed bytes=5873/68309 2010-03-11 15:52:57 IMAP(my_user(a)mydomain.com): Info: Disconnected in IDLE bytes=4514/547136 2) He generates the troublesome emails from a notification system in Craiglist .... We can see the email hitting the inbox (we also see in Postfix this email going to Dovecot) 2010-03-11 15:54:48 deliver(my_user(a)mydomain.com): Info: From=noreply(a)craigslist.org : msgid=<20100311205447.0C0FE118B04(a)web8p.int.craigslist.org> : saved mail to INBOX 3) Email is deleted !!! 2010-03-11 15:54:49 IMAP(my_user(a)mydomain.com): Info: delete: uid=10719, flags=(\Deleted \Recent $Junk), msgid=<20100311205447.0C0FE118B04(a)web8p.int.craigslist.org>, from=craigslist.org <noreply(a)craigslist.org>, subject=POST/EDIT/DELETE : (accounting/financejobs) Test Post 2010-03-11 15:54:49 IMAP(my_user(a)mydomain.com): Info: expunge: uid=10719, flags=(\Deleted \Recent $Junk), msgid=<20100311205447.0C0FE118B04(a)web8p.int.craigslist.org>, from=craigslist.org <noreply(a)craigslist.org>, subject=POST/EDIT/DELETE : (accounting/finance jobs) Test Post , size=2776 Who is deleting this email ? I can see the flag $Junk ... perhaps some filter somewhere is seeing that flag and proceeding to delete it. If I understand sieve filters at the server side, they will act in the deliver process. So once the email is saved into INBOX, sieve filters will not count. Am I right?

Yes, I´ve read these doc. I was just considering if someone had any experience with Mogile in email environment. Well, actually I´m trying to figure out if one of those nosql systems can store and scale email systems (ie, mailboxes - instead of maildir). I know mysql is always quoted as an option and discussed sometimes in the list. I think it´s an unnecessary overhead and bottleneck. As brainstorm.

[Dovecot] patch: allow proxy to lookup host by name
by Martin F. Foster 12 Mar '10

12 Mar '10

This patch allows the dovecot proxy processes to lookup the destination host by name instead of IP address. Tested agains 1.2.10, expected to work against 1.2.11. The patch is pretty straightforward, it's making it work within the restrictions of the login process that's more interesting. I have made some changes to the wiki (pending approval) to - enhance the discussion of proxy with LDAP http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy - discuss the implication of this patch w.r.t. the login_chroot configuration parameter: http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy/HostLookup Feedback is appreciated, particulary from a security standpoint. Cheers, -Martin Foster martin_foster(a)netlog.net dump of wiki info, for the lazy. It will look better if viewed from the URL: http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy/HostLookup For all released versions of Dovecot, the "host" referred to in a proxy or proxy_maybe lookup must be an IP address see: the main PasswordDatabase/ExtraFields/Proxy <http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy> page for more info A patch is available to enable lookups, but it has some imporant caveats due to the nature of the LoginProcess <http://wiki.dovecot.org/LoginProcess> that the proxy function is a part of. This page exists to discuss these. The Problem Proxying is done from the dovecot login processes, both pop3-login & imap-login call code in src/login-common/login-proxy.c to handle the proxying to the given host. If the host is not an IP address, name resolution must be done. Two options from dovecot's configuration: 1. Dovecot running with roots Dovecot is started as root and drops privileges later; this is the recommended way of running Dovecot. Set by the config option: login_chroot = yes. In this mode, the login process is chrooted to login_dir, from which the proposed patch adds name resolution. Resolution is done via dovecot's net_gethostbyname() function - a wrapper for getaddrinfo/gethostbyname depending on compile-time platform support. These functions need access to the name service switch configuration, then whatever dependencies are required to consult the host resolution databases stipulated. so, if the /etc/nsswitch.conf hosts entry is: hosts: dns files Then the system will need access to /etc/resolv.conf and the nss_dns libraries for "dns" lookup, and /etc/hosts for "files" lookup. The exact files will vary by platform/operating system, but these all need to be available in the chroot for the lookup to succeed. and, if dovecot.conf has: login_chroot = yes login_dir = /var/run/dovecot/login login_user = dovecotuser Then for the nsswitch.conf entry above, the following files need to be copied (not symbolically linked!) to the chroot. This example is for a 64-bit RHEL5 system, with 64-bit dovecot daemon. Ownership of the new directories must be set to whatever the login_user is set to. mkdir /var/run/dovecot/login/etc mkdir /var/run/dovecot/login/lib64 cp /etc/nsswitch.conf /etc/resolv.conf /etc/hosts /var/run/dovecot/login/etc cp /lib64/libnss_dns.so.2 /var/run/dovecot/login/lib64 chown -R dovecotuser:dovecotuser /var/run/dovecot/login/etc chown -R dovecotuser:dovecotuser /var/run/dovecot/login/lib64 Remember that the ownership of the login_dir itself *must not* be changed. So: # ls -ld /var/run/dovecot/login/ drwxr-x--- 4 root dovecotuser 4096 Mar 12 06:48 /var/run/dovecot/login/ Troubleshooting If the lookup fails because of a perceived lookup-in-chroot issue, an error message of this form will be printed to the logs dovecot: pop3-login: proxy(test(a)domain1.test): cannot resolve mailhost.domain1.test. If name resolution is working outside dovecot, it may be a chroot issue. See LoginProcess on wiki, and login_dir& login_chroot in config. Clients will receive a much less descript general error message, for example with POP3: -ERR [IN-USE] Account is temporarily unavailable. Things to check 1. does name resolution work for normal users? the dovecot user? 2. are all the files required by the Name Service Switch's configuration available? Use a process tracing tool such as strace or truss against the pop3-login or imap-login processes to check. 3. are other security measures interfering? eg: 1. SELinux <http://en.wikipedia.org/wiki/Security-Enhanced_Linux> (RedHat <http://www.redhat.com/rhel/> EL, CentOS, Oracle EL) 2. AppArmor <http://en.wikipedia.org/wiki/AppArmor> (SuSE, Ubuntu?) 3. RBAC (Solaris, OpenSolaris <http://en.wikipedia.org/wiki/Open_Solaris>) Caveats This procedure allows the chroot'ed login to do something, which forms a security risk if the libraries in the chroot are exploitable. It will be up to the operator to ensure that the copy of the files in the chroot get updated whenver the copies in the real filesystem do. On systems where the chroot is on the same filesystem/partition that the original file copies are, hard links (again: no soft links!) could be used to accomplish this. 2. Dovecot running without roots (RootLess) Dovecot is started as whatever user/group is used to start the master daemon. See the discussion on Rootless <http://wiki.dovecot.org/HowTo/Rootless> for reasons why this is not the recommended way of running Dovecot, which includes a discussion on how this is more likely to be less secure. In dovecot.conf, rootless is selected by setting: login_chroot = no In this mode, the login process will have access to the required Name Service Switch configuration files and their dependencies if the user that started dovecot did. No further configuration is required for the proxy process to lookup hostnames.

[Dovecot] Scalability plans: Abstract out filesystem and make it someone else's problem
by Timo Sirainen 12 Mar '10

12 Mar '10

This is something I figured out a few months ago, mainly because this one guy at work (hi, Stu) kept telling me my multi-master replication plan sucked and we should use some existing scalable database. (I guess it didn't go exactly like that, but that's the result anyway.) So, my current plan is based on a couple of observations: * Index files are really more like memory dumps. They're already in an optimal format for keeping them in memory, so they can be just mmap()ed and used. Doing some kind of translation to another format would just make it more complex and slower. * I can change all indexing and dbox code to not require any locks or overwriting files. I just need very few filesystem operations, primarily the ability to atomically append to a file. * Index and mail data is very different. Index data is accessed constantly and it must be very low latency or performance will be horrible. It practically should be in memory in local machine and there shouldn't normally be any network lookups when accessing it. * Mail data on the other hand is just written once and usually read maybe once or a couple of times. Caching mail data in memory probably doesn't help all that much. Latency isn't such a horrible issue as long as multiple mails can be fetched at once / in parallel, so there's only a single latency wait. So the high level plan is: 1. Change the index/cache/log file formats in a way that allows lockless writes. 2. Abstract out filesystem accessing in index and dbox code and implement a regular POSIX filesystem support. 3. Make lib-storage able to access mails in parallel and send multiple "get mail" requests in advance. (3.5. Implement async I/O filesystem backend.) 4. Implement a multi-master filesystem backend for index files. The idea would be that all servers accessing the same mailbox must be talking to each others via network and every time something is changed, push the change to other servers. This is actually very similar to my previous multi-master plan. One of the servers accessing the mailbox would still act as a master and handle conflict resolution and writing indexes to disk more or less often. 5. Implement filesystem backend for dbox and permanent index storage using some scalable distributed database, such as maybe Cassandra. This is the part I've thought the least about, but it's also the part I hope to (mostly) outsource to someone else. I'm not going to write a distributed database from scratch.. This actually should solve several issues: * Scalability, of course. It'll be as scalable as the distributed database being used to store mails. * NFS reliability! Even if you don't care about any of these alternative databases, this still solves NFS caching problems. You'd keep using the regular POSIX FS API (or async FS api) but with the in-memory index "cache", so only a single server is writing to mailbox indexes at the same time. * Shared mailboxes. The filesystem API is abstracted, so it should be possible to easily add another layer to handle accessing other users' mails from both local and remote servers. This should finally make it possible to easily support shared mailboxes with system users.

[Dovecot] troubles with expire plugin
by Denis Fateyev 11 Mar '10

11 Mar '10

Hello there, Now I'm using `expire` plugin and getting troubles with cronjob (from user `exim`): /usr/sbin/dovecot --exec-mail ext /usr/libexec/dovecot/expire-tool.sh Fatal: setgid(12(mail)) failed with euid=93(exim), gid=93(exim), egid=93(exim): Operation not permitted (This binary should probably be called with process group set to 12(mail) instead of 93(exim)) The same error occurs when I run this command from `exim` user with sudo. My dovecot v1.2.11 configuration: dovecot.conf ----------------- ... socket listen { master { path = /var/run/dovecot/auth-master mode = 0660 user = exim group = mail } client { path = /var/spool/exim/private-auth mode = 0660 user = exim group = mail } } ... userdb-sql.conf ------------------------ # exim uid: 93, mail gid: 12 user_query = SELECT CONCAT('/var/mail/', maildir) AS home, \ CONCAT('maildir:/var/mail/', maildir) AS mail, 93 AS uid, 12 AS gid, \ CONCAT('*:storage=', quota, 'B') AS quota_rule, \ 'storage=90%% /usr/libexec/dovecot/quota_warning.sh 90' AS quota_warning \ FROM mailbox WHERE username = '%u' AND active = '1' password_query = SELECT username AS user, password, \ CONCAT('/var/mail/', maildir) AS userdb_home, \ CONCAT('maildir:/var/mail/', maildir) AS userdb_mail, \ 93 AS userdb_uid, 12 AS userdb_gid, \ CONCAT('*:storage=', quota, 'B') AS userdb_quota_rule, \ 'storage=90%% /usr/libexec/dovecot/quota_warning.sh 90' AS userdb_quota_warning \ FROM mailbox WHERE username = '%u' AND active = '1' ( maybe, is any additional information required? ) All working fine with dovecot except this issue with `expire` plugin. How to avoid it? As I see, it's working if I run this command from `root` instead of `exim`, but I don't think it will be right to leave it in the root's crontab. Thanks, --- wbr, Denis.
