[Dovecot] INBOX. namespace
by Brian Candler 27 Mar '10

27 Mar '10

I am trying to configure dovecot-1.2.11 to have the same IMAP namespacing as courier-imap as per http://wiki.dovecot.org/Migration/Courier, but failing badly. I have a test maildir with INBOX and folder 'junk'. Without fiddling with namespaces, this works fine: there are 91 msgs in INBOX and 2 in junk. a namespace * NAMESPACE (("" ".")) NIL NIL a OK Namespace completed. a examine INBOX ... * 91 EXISTS ... a OK [READ-ONLY] Select completed. a examine junk ... * 2 EXISTS ... a OK [READ-ONLY] Select completed. Now I make the following addition to dovecot.conf: namespace private { separator = . prefix = INBOX. inbox = yes hidden = no } After this the inbox appears to be empty, and I cannot select the junk folder at all: a namespace * NAMESPACE (("INBOX." ".")) NIL NIL a OK Namespace completed. a examine INBOX * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS ()] Read-only mailbox. * 0 EXISTS * 0 RECENT * OK [UIDVALIDITY 1269605071] UIDs valid * OK [UIDNEXT 1] Predicted next UID * OK [HIGHESTMODSEQ 1] Highest a OK [READ-ONLY] Select completed. a examine INBOX.junk * OK [CLOSED] Previous mailbox closed. a NO Mailbox doesn't exist: junk Furthermore I can select "INBOX.INBOX" (although that's empty as well) a examine INBOX.INBOX * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS ()] Read-only mailbox. * 0 EXISTS * 0 RECENT * OK [UIDVALIDITY 1269605071] UIDs valid * OK [UIDNEXT 1] Predicted next UID * OK [HIGHESTMODSEQ 1] Highest a OK [READ-ONLY] Select completed. a examine INBOX.INBOX.INBOX * OK [CLOSED] Previous mailbox closed. a NO Mailbox doesn't exist: INBOX.INBOX a examine junk a NO Unknown namespace. Have I misunderstood what I'm supposed to be doing here? The other relevant setting is: mail_location: maildir:%h but I've not changed this; as I say, this works just fine without meddling with namespaces. Many thanks, Brian.

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. Any suggestions on where to look to figure out what's causing this? I don't see that error at all in the past 4 weeks of logs in production.

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

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

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

(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

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

If using Unstable is it recommended to stay or use the newer ones? 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

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.

[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.

Feb 20 19:34:06 ubuntu-test dovecot: auth: sql(test,192.168.156.99): SELECT home, mail, uid, gid, concat('*:storage=', quota_limit, 'MB') AS quota_rule FROM users WHERE username = 'test' ... Feb 20 19:34:06 ubuntu-test dovecot: imap(test): Quota root: name=user backend=dict args=:proxy::dictionary Feb 20 19:34:06 ubuntu-test dovecot: imap(test): dict quota: user=test, uri=proxy::dictionary, noenforcing=0 ... Note there is no "Quota rule". However it seems to work by adding "quota_rule = *:storage=1024MB" directly to plugin.conf: ... Feb 20 19:39:15 ubuntu-test dovecot: imap(test): Quota root: name=user backend=dict args=:proxy::dictionary Feb 20 19:39:15 ubuntu-test dovecot: imap(test): Quota rule: root=user mailbox=* bytes=1073741824 messages=0 Feb 20 19:39:15 ubuntu-test dovecot: imap(test): dict quota: user=test, uri=proxy::dictionary, noenforcing=0 ... Has there anything changed in dovecot 2.0 in this perspective?

[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 ? Regards, Oliver Eales

[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
