[Dovecot] mbox and dual-use folders?
by John Robinson 12 Feb '07

12 Feb '07

Feature request: please can we have support for messages stored in mbox files, but folders containing both messages and folders. I think this could be done for a folder called e.g. dovecot-list by having an mbox file called dovecot-list and a directory called dovecot-list.folder (or whatever, says he handwaving away name clashes which can be worked around like they are in maildirs). This may be a subset or variant of http://wiki.dovecot.org/FeatMboxMaildir Cheers, John.

[Dovecot] IMAP/POP3 server with proxy feature
by Jasper Bryant-Greene 12 Feb '07

12 Feb '07

We are currently evaluating the migration from a proprietary, legacy mail server onto Dovecot for 20,000+ virtual domains. This is a big job and we intend to do it by initially proxying connections through to the legacy server, and moving customers over in batches by turning off the proxy feature for them. In the manual it states "This model is still a bit unfinished in current code" [1]. What is needed to get this production-quality? I'm happy to help out with any work required.

[Dovecot] Shared folders plans for the future
by Timo Sirainen 11 Feb '07

11 Feb '07

So while driving for several hours in my car recently and having nothing else to do, I started thinking how they could be done. I think the "public folders" configuration will stay as it is now. Does it really even need anything else? The problematic case is how the users can share their mailboxes to other users. There are two problems related to it: 1) How to get (quickly) a list of another user's mailboxes that I have access to? 2) How to get quickly a list of all users who have mailboxes that I have access to? The 1) problem is easier to solve. Create a directory listing all the mailboxes that are shared to at least someone (have ACLs set). It could be configured like: namespace shared { # IMAP namespace prefix, %u expands to shared user prefix = user/%u/ # Directory containing symlinks to user's all shared mailboxes share_dir = ~/Maildir/shared # Where to store indexes for other users' accessed mailboxes index_dir = ~/Maildir/others-indexes } The ~/Maildir/shared directory could then contain symlinks to all the shared mailboxes. The directory list could probably be in Maildir++ layout even though the symlinks would point to mboxes. This requires adding code that can handle mixed maildir/mbox directories, but it'll come anyway.. The 2) problem is more difficult. There are 3 choices: a) Use a shared database file. lib-dict could be used for this, so the database could be in SQL or in a berkeley db file. The downside to this is that the file needs to be readable and writable to everyone, so if users have shell access the users could break the file. They dictionary would contain data in format "<destination_user>/<sharing_user>" = 1 and "<destination_group>/<sharing_user>" = 1, ie. the value would be ignored and only the existence of the keys would be important. Then iterating through "<my_username>/*" and "<all_my_groups>/*" would list the users who probably have mailboxes where I have access to. b) Use a directories with sticky bit set. Well, basically the same idea as in a), except filesystem would be used. Actually perhaps this could be made another lib-dict backend.. c) Brute force: Just assume everyone potentially have shared mailboxes. Get the list of users by readdir()ing through /home (configurable). I guess each of these could be made an option.. So something like: namespace shared { .. # a) shared_dict = db:/var/lib/dovecot/shared-mailboxes.db # b) shared_dict = dir:/var/lib/dovecot/shared-mailboxes # c) shared_dict = bruteforce:/home } I'm currently also implementing a "mailbox list index", which contains a list of all the user's mailboxes and some useful metadata for them, such as number of messages and so on. So that STATUS command wouldn't need to open the mailbox index files if they haven't changed. The mailbox list index updating is normally done when directory's mtime has changed. For list of shared users that would also work in 2b) and 2c) cases, but for 2a) I'd either have to always sync everything or alternatively add some sequence/<dest_user/group>=# value which is grown for each update, and the syncing is done only when the sequence is updated.

[Dovecot] help needed - dovecot-ldap authentication
by Vidyasagar Warge 10 Feb '07

10 Feb '07

I am trying to set a up mail server on a ubuntu edgy machine. I followed the howto at http://wanderingbarque.com/howtos/mailserver/mailserver.html . I am able to configure everything except dovecot-ldap authentication :(. After struggling with it for a week I decided to seek help. The current version of dovecot is v1.0 RC21 and the version used for the howto is v0.99.10.9. I installed & tried to configure both versions but none of them was able to authenticate a user from ldap. I noted some differences in syntax of the dovecot.conf files of both the versions. It seems that the ldap documentation at dovecot site is from the old version of dovecot ( I might be wrong on this!). So if anyone can tell me how to configure the current version of dovecot with openldap? Please help me! I am eagerly waiting for your response. Regards, Vidyasagar

[Dovecot] Lda does not query pgsql
by Tognini Samuele 09 Feb '07

09 Feb '07

Hi, I don't know if it's a bug or my configuration fault, but LDA does not work as i expect. Dovecot auth connects to a pgsql database that mirrors Nis users infos, but it has also quota settings because i'd like to use a per-user quota environment. Mailserver and Postfix authenticates users with Nis (through PAM), while imap and local delivery (with the postfix mailbox_command setting) are left to dovecot mechanism. Imap works perfectly, dovecot retrieves authentication and quota setting from database, but dovecot LDA seems to not query any database (and nothing is logged) , so that quota is not retrived and message is not bounced when user is overquota. You can see it in the verbose log: deliver(tognini): 2007-02-08 12:25:02 Info: Loading modules from directory: /usr/lib/dovecot/modules/lda deliver(tognini): 2007-02-08 12:25:02 Info: Module loaded: /usr/lib/dovecot/modules/lda/lib10_quota_plugin.so deliver(tognini): 2007-02-08 12:25:02 Info: Module loaded: /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin. so deliver(tognini): 2007-02-08 12:25:02 Info: mbox: data=/home/t/tognini:INBOX=/var/spool/mail/tognini deliver(tognini): 2007-02-08 12:25:02 Info: mbox: root=/home/t/tognini, index=/home/t/tognini, inbox=/var/spool/mail/tognini deliver(tognini): 2007-02-08 12:25:02 Info: cmusieve: Using sieve path: /home/t/tognini/.dovecot.sieve deliver(tognini): 2007-02-08 12:25:02 Info: msgid=<20070208112502.7706B3273D6(a)arturo.cli.di.unipi.it>: saved mail to INBOX If i set quota variable in dovecot.conf, still no query but the global variable is used for all users: ... deliver(tognini): 2007-02-07 12:33:04 Info: dirsize quota limit = 1024kB ...

[Dovecot] why is there email in my mbox file?
by Kendall Shaw 09 Feb '07

09 Feb '07

Hi, I've installed dovecot-imapd under ubuntu. My account and root are the only email accounts on my computer. I transitioned from using GNUS with fetchmail, exim and movemail, to gnus with exim, fetchmail and imap, so I've kept the mbox format email instead of changing to maildir. This works okay, except my mbox file is giant. I expected dovecot to take the mail out of the mbox file and put it somewhere. But, I see there's a big mbox file (/var/mail/me) that keeps growing. Is dovecot using that as the store of messages? If I were to move to using maildir instead of mbox, what is going to happen to my existing mail? Kendall

Hi A user here has a strange problem when I moved my imap server from UW-IMAP to Dovecot. A folder created monthes ago with mozilla mail (windows client) became suddenly invisible when I stopped UW then started Dovecot. I really think that IMAP created folders a fully compatibles between UW and Dovecot but I'm curious to know from where does come this trouble ??? Anyone had experienced the same problem ?

[Dovecot] negative quota usage causes over-quota messages with dictionary quota backend
by Marshal Newrock 07 Feb '07

07 Feb '07

Using dovecot 1.0.rc21, with quotas being stored in mysql, I have found that if the quota usage stored is negative, then when a message is given to dovecot deliver, the account is reports as being over quota. The squirrelmail quota usage plugin says that the quota is at around 40 million percent (I should have written down the exact number), though I don't know if that's squirrelmail or dovecot coming up with that number. At a guess, I'd say there's an unsigned int being used where the result can be signed. I'm using MySQL 5, so for an easy workaround, I added a trigger that sets the quota usage to 0 if it goes less than 0. I could probably also set the field to unsigned int, but I haven't tested what mysql does if you try to change an unsigned int field such that it would be negative. -- Marshal Newrock, Ideal Solution LLC http://www.idealso.com

[Dovecot] OTP?
by Micah Cowan 07 Feb '07

07 Feb '07

Hello, I was wondering where I might find more information about using OTP as an authentication protocol with dovecot. In searching, I found a thread from 2004, but not much information about how it has progressed from then. I also saw some promising patches from mid-last year, which if I had to guess are probably the addition of support for the SASL OTP mechanism. Is this available in a release yet? (And, also: does anyone know of Linux mail clients that support the OTP SASL mechanism? I'm hoping Thunderbird might...). If not, is it possible to make it work currently with PAM (or, if that's not possible, maybe Cyrus SASL)? It would be okay with me if it can work with PAM but not prompt with the seed/series number: I can scratch off keys no prob. I tried briefly to get it to work through PAM, and in fact opieinfo told me that the series was being decremented, but auth.log gives Feb 6 15:41:46 mabruk dovecot-auth: (pam_unix) authentication failure; logname= uid=0 euid=0 tty= ruser= rhost=x.x.x.x user=micah ssh works fine with the same PAM settings (both include common-auth, which has:) auth sufficient pam_opie.so auth sufficient pam_unix.so nullok_secure auth required pam_deny.so -- Micah J.

[Dovecot] Indexing Performance Question (was tpop3d vs dovecot)
by Nate 06 Feb '07

06 Feb '07

Since posting the previous thread we've setup a new system (Opteron 2.0ghz, 1gb ram, Fedora 6) for testing. I am hoping somebody very familiar with the indexing portion of dovecot can shed some light on this for me. After much testing, I've come to one primary conclusion that dovecot is possibly unnecessarily scanning or reading files within the maildir directories. Take a mailbox for instance (my test one has 71570 emails in the cur/ folder so the process runs long enough to get data of what it's doing). Follow these steps: 1. First pop3 connection. With no index files whatsoever, it takes nearly a full 10 minutes at 100% io load to scan the 71570 files (748M) directory and build the index files from scratch which look like this: -rw------- 1 postfix postdrop 839K Feb 1 00:43 dovecot.index -rw------- 1 postfix postdrop 1.9M Feb 1 00:57 dovecot.index.cache -rw------- 1 postfix postdrop 560K Feb 1 00:43 dovecot.index.log -rw------- 1 postfix postdrop 3.1M Feb 1 00:43 dovecot-uidlist While it's building index i see a lot of these fly by in lsof pop3 2023 postfix 8r REG 8,3 14425 285947 /var/spool/mail/test.visp.net/natetest/cur/1128488047.V902I7d42e.s3.visp.net:2, No problem here, the disk can only go as fast as the disk can go and thats a *lot* of mail. Although, one curious thing here, it appears that dovecot is reading or at least scanning the entire contents of the files within the cur/ directory to generate an index. I assume this by watching my disk cache go from 100MB to 600MB. Is it necessary to do that or only read the top X lines of each file, is that even possible? 2. Second connection. Near instantaneous results from a login and LIST. Cannot perform an lsof fast enough to see what files it's opening. This step can be repeated with nearly the same results. *rebooted machine to clear all cache* 3. Third connection. It takes ~40 seconds to display a LIST after login. The index files are untouched; however, during the 40 seconds I'm waiting, I can catch a few of these in lsof. pop3 1971 postfix 10r REG 8,3 4196 205963 /var/spool/mail/test.visp.net/natetest/cur/1157863512.V902I1f3867.s3.visp.net:2,S This tells me even though there is no new email, it is re-scanning the cur/ directory somewhat. It doesn't take near as long as the initial index build, but certainly takes longer than it would for the system to read any or all of the listed index files above. Why would dovecot need to even enter cur/ if the index file is up to date? Is it verifying that the index file is up to date by re-reading some or all of the many files in cur/? If so, could it not get the info it needs by simply doing the equivalent of a ls, which would take considerably less time? The disk cache is only filled up an additional 30meg vs an additional 500meg from connection 1, so it's certainly not reading as much data. (also makes me wonder why the initial scan/index build could not use this lesser time consuming function if thats what it's doing). Additional information: Running strace on the initial indexing looks like this... ------------------------------------------- open("/var/spool/mail/test.visp.net/natetest/cur/1115929738.V902I67c13.test.visp.net:2,", O_RDONLY) = 8 fstat(8, {st_mode=S_IFREG|0600, st_size=4667, ...}) = 0 pread(8, "Return-Path: <mehl8nl3n8osm3r83a"..., 4096, 0) = 4096 pread(8, "zdik8dyrnffv6bbrue.itownshipno12"..., 4095, 4096) = 571 pread(8, "", 3524, 4667) = 0 close(8) = 0 open("/var/spool/mail/test.visp.net/natetest/cur/1115931742.V902I67c42.test.visp.net:2,", O_RDONLY) = 8 fstat(8, {st_mode=S_IFREG|0600, st_size=3881, ...}) = 0 pread(8, "Return-Path: <sender-5-8759012-9"..., 4096, 0) = 3881 pread(8, "", 215, 3881) = 0 close(8) = 0 ------------------------------------------- Running strace on the 3rd connection looks like this... ------------------------------------------- open("/var/spool/mail/test.visp.net/natetest/cur/1114490671.V902I6011f.test.visp.net:2,", O_RDONLY) = 10 fstat(10, {st_mode=S_IFREG|0600, st_size=5367, ...}) = 0 pread(10, "Return-Path: <qflfmq82vz8zg-u6ci"..., 4096, 0) = 4096 pread(10, "gs/rpoc_District6Spauldings.php?"..., 4095, 4096) = 1271 pread(10, "", 2824, 5367) = 0 close(10) = 0 open("/var/spool/mail/test.visp.net/natetest/cur/1114496568.V902I60bf5.test.visp.net:2,", O_RDONLY) = 10 fstat(10, {st_mode=S_IFREG|0600, st_size=2047, ...}) = 0 pread(10, "Return-Path: <removed(a)aaa-calif.c"..., 4096, 0) = 2047 pread(10, "", 2049, 2047) = 0 close(10) = 0 Thank you for the help! - Nate

[Dovecot] Problem with vpopmail auth
by Fred Moyer 06 Feb '07

06 Feb '07

Hello, I've install 1.021 and am having some problems getting vpopmail authentication to work correctly (running 0.99 in production, upgrading to 1.021). I'm using vpopmail-5.4.16. Here are the authentication debug statements in the log, my dovecot.conf changes from default, and the schema of my vpopmail database. Any ideas / suggestions? I've commented out all authentication except for vpopmail. I took a look around the source but am not that familiar with the vpopmail api.

[Dovecot] Big problems after upgrade from beta8 (FC5) to rc21
by Jim Garrison 06 Feb '07

06 Feb '07

After upgrading a working system from FC5's beta8 to rc21, one vhost is failing with: > dovecot: Feb 05 09:54:30 Error: POP3(user(a)mydomain.com): > open(/var/mail/vhosts/mydomain.com/david/user, O_CREAT) failed: Not a > directory > dovecot: Feb 05 09:54:30 Error: POP3(user(a)mydomain.com): > mkdir_parents(/var/mail/vhosts/mydomain.com/user/.imap/INBOX) failed: > Not a directory > dovecot: Feb 05 09:54:30 Error: POP3(user(a)mydomain.com): Couldn't open > INBOX: Internal error occurred.

If so, how do I recover so users can retrieve mail again? Thx.

[Dovecot] LDAP auth_bind=yes in rc21 = goodness
by Adrian Close 06 Feb '07

06 Feb '07

Hi all, I finally got a chance to try out the fix for the LDAP auth_bind=yes issues in production (using rc21). It seems to be working just fine even after 24 hours of severe abuse. Incidentally, I had switched to bsdauth+login_ldap (on OpenBSD) which was often OK, but occasionally I would see Postfix smtpd throttled with SASL errors due to "connection refused" on the Dovecot authentication socket. This may just have been due to increased LDAP server load (Dovecot's internal LDAP generates much less). Thanks Timo! (And thanks Brad for updating the port) Adrian.

[Dovecot] minor kerberized dovecot build issue
by Dan Price 05 Feb '07

05 Feb '07

Hi all, again, I'm not knowledgeable about Kerberos, but we have a few users who use it to make sure that it works well on Solaris... so, they would like a Kerberized IMAPd. I tried compiling dovecot --with-gssapi on Solaris Nevada (the current development release), and the configure script choked for a couple of reasons. First, script uses 'grep -qv' in the case that you specify --with-gssapi to run some test. Unfortunately, Solaris doesn't have 'grep -q'. There's a note in GNU grep's manpage about this problem and a note that portable scripts should just redirect to /dev/null. Once I fixed this problem, I got: configure: WARNING: gssapi/gssapi.h: present but cannot be compiled configure: WARNING: gssapi/gssapi.h: check for missing prerequisite headers? configure: WARNING: gssapi/gssapi.h: see the Autoconf documentation configure: WARNING: gssapi/gssapi.h: section "Present But Cannot Be +Compiled" configure: WARNING: gssapi/gssapi.h: proceeding with the preprocessor's result configure: WARNING: gssapi/gssapi.h: in the future, the compiler will take +precedence configure: WARNING: ## ---------------------------------- ## configure: WARNING: ## Report this to dovecot(a)dovecot.org ## configure: WARNING: ## ---------------------------------- ## For whatever reason, on Solaris /usr/bin/krb5-config does not like the syntax 'krb5-config --cflags gssapi' (ditto with --libs). I found that removing the 'gssapi' part from the configure script fixed the problem, but I imagine this must break some other OS. If need be, I can follow up with the Kerberos team about this. Once I made these minor changes, I also had to add -lgss to the src/auth makefile's compile line. After that, I had no problem getting this to compile, although we have not yet tested it. -dp -- Daniel Price - Solaris Kernel Engineering - dp(a)eng.sun.com - blogs.sun.com/dp
