[Dovecot] POP3 only - why is cur/ growing?
by Wally Winchester 09 Jan '06

09 Jan '06

Hi, I use Sarge's dovecot for a pop3 mail collection server. IMAP is not used at all. It works well, but I would like to know why one of the accounts also keeps a copy of all e-mail copies in the cur/ folder? Thanks a lot, Wally -- Wally Winchester wally_winchester(a)fastmail.fm -- http://www.fastmail.fm - The way an email service should be

[Dovecot] Running dovecot-lda
by Linus Nordberg 08 Jan '06

08 Jan '06

Hi, I'm planning on setting up dovecot with dovecot-lda, for sieve support. What does the list have to say about versions to use? I prefer stability over features but sieve has to be there. Does anybody use the combination dovecot 1.0 alpha5 and dovecot-lda 0.1 with success or would you recommend running -lda from CVS? If so, is there any point in time that's better than another? And, will dovecot 1.0 alpha5 do for -lda from CVS? Finally, are there any release plans for dovecot-lda that can be shared? Thanks, -- Linus

[Dovecot] Documentation updates in Wiki
by Timo Sirainen 08 Jan '06

08 Jan '06

I started writing a new front page for wiki.dovecot.org: http://wiki.dovecot.org/NewIndex This is partially based on the comments in Documentation thread starting from here: http://dovecot.org/list/dovecot/2005-July/008076.html "A simple Dovecot installation" section is pretty much finished from my point of view. I hope it's clear enough for anyone wanting to install a working Dovecot server. Suggestions are welcome of course. You're also welcome to just edit the pages directly. I'll get email notifications of all page changes, so if I see changes that I don't think belong in there, I'll just remove them and maybe move them elsewhere (so don't add too much text without asking :). I'm not sure about what exactly should be visible in the front page. Currently there's probably too much. But I think it's better to show more than too little, so that new people can just look at the page and quickly pick up the interesting keywords without having to click through multiple pages. Maybe most of the sub-sections in "full guide" section could be listed only under those root sections. So that it becomes something like: * Starting guidelines * Authentication configuration * Mail configuration * Namespaces * Shared folders * SSL * POP3 * Dovecot LDA * Full configuration file reference * Examples / Scenarios I'd leave namespaces and shared folders there so that they can be easily found. I'm not sure where to put "full configuration file reference" or what exactly to call it. The same goes for Examples/Scenarios. Tuning should maybe be only part of "full guide". "Generic information about mail servers" is meant for discussion of mail server components, protocols, etc. without being too much Dovecot-specific. It's partially for "mail server newbies", but also would contain some "hard core" information about how things really work (mailbox format and user authentication especially). Anyway, if you have time please start adding the missing pages and writing to them. Even if you only give a FIXME-list that others can then fill out :) My school starts again at monday, and I'll be too busy to do anything else than that and work for the rest of January (after that only finals, yay).

Let me know how you like this one. This assumes one config parameter. The non-null of auth_bind_userdn overrides auth_bind = yes. I'm using this patch now on cvs head. Comments are always welcome. Thanks much, Geff

[Dovecot] Questions regarding quota
by Stian Jordet 07 Jan '06

07 Jan '06

Hi, I have some trouble trying to test the quota plugin. First off all, it says in the wiki: "Dovecot 1.0 supports quota using a quota plugin. It's currently discussed in Dovecot LDA page and it supports only very simple quota calculation which is suitable only for mboxes. Maildir++ quota support will come later." Does that mean that it won't work at all with Maildir++, or just that it's slow? Second; there are two plugins? One in src/plugins/quota and one ine src/plugins/imap-quota. What's the difference? Is one for imap-quota and the other for fs-quota? (I would love that!) But third and most importantly; I can't get it too work. I'm using CVS from tonight (which fixed the missing symbol bug). But neither when I'm using static userdb nor LDAP as explained in the wiki I can't get it to work. I'm not really sure of the getquota syntax, but whatever I try, I get: a OK No quota. So please, enlighten me! :) Best regards, Stian

[Dovecot] FETCH FLAGS in response to SORT and SEARCH commands
by Michael Doppler 06 Jan '06

06 Jan '06

[Dovecot] Dovecot Version Numbers - Let's drop the Alpha?
by Marc Perkel 04 Jan '06

04 Jan '06

I'd like to make a suggestion. Let's drop the Alpha and come out with an official version 1.0. Here's my reasons. The 0.9x version are obsolete and people should be using the 1.0 Alpha versions which seem to me to do everything the previous versions did and more. It's as full featured and stable as all other IMAP servers and in my opinion is ready to be called 1.0. The "Alpha" label scares people off and with the 0.9x version being obsolete I think it creates confusion for new users. It created confusion for me when I converted to dovecot, and distros are less ,ikely to include versions with the Alpha label. Once you go to 1.0 you can start a 1.1 alpha series and finish it up. I know Timo has high standards but as a marketing issue I think that the Alpha label needs to go to get people to accept and use 1.0 in production.

[Dovecot] problems connecting to the Problems connecting to mysql
by Alfonso Fernández Vázquez 04 Jan '06

Hi, I'm trying to setup a mailserver running postfix and dovecot with mysql as database backend. Postfix is already running and delivers mails just fine. Unfortunately, dovecot has great problems connecting to the database (using username + password). Found that two threads about the same issue but none of them solves the problem http://dovecot.org/list/dovecot/2005-April/006770.html http://dovecot.org/list/dovecot/2005-August/008394.html I am using: dovecot-1.0.alpha5 mysql 5.0.17-1 Please, can anyone help?

[Dovecot] Intermittent "Password Mismatch" errors
by dan＠ipws.com 03 Jan '06

03 Jan '06

Hello - I have had a problem the last few days with Dovecot reporting intermittent "Password Mismatch" errors for pretty much every client. Not all the time, maybe 1 out of every 10 connections. I cannot pinpoint where the process may be failing. I am using a MySQL backend to store user information in, and Dovecot queries that database directly. It works fine, but it seems as if Dovecot has a problem connecting to the SQL server for this information, instead of doing something smart, it just reports a password mismatch. I've turned on debugging and verbose logging, but I can't see exactly *why* the process fails on occasion. MySQL is tuned appropriately, and there's no reason why Dovecot cannot connect to the server. I'm wondering if anyone has seen this, and if so, what they've done about it. Because honestly, I'm lost. Thanks -dant

[Dovecot] very slow imap opens in pine after moving maildirs to new drive
by Dave Lugo 03 Jan '06

03 Jan '06

Hi, I've been running dovecot-0.99.10 for the past several years, with virtually no problems. Lately, I noticed that the filesystem holding my users' imap maildirs was getting close to full. So... last night, I used tar to copy /var/spool/imap to a new drive (9G scsi, reiserfs) that I then mounted under /var/spool/imap (after moving the old dir aside). After the move, what would take pine a handful of seconds, with the load average barely breaking .40, now takes several minutes, with a load average spike to nearly 3. I must admit to being rather puzzled by this, as I would not have expected the move to result in worse performance. Do I need to figure out what the index file names are, and delete those? Any suggestions greatly appreciated - as even closing pine now takes nearly 5 minutes, whereas when dovecot talks to my old imap dir (I've tested this), closing the session takes no more than 10 seconds. server is Mandrake 9.1, 2.4.21-0.13mdkenterprise, P4 2.6GHz, 1G RAM 9G U2W SCSI system disk, 9G U2W SCSI (and big*ss IDE drive for /users). Each of the scsi drives is on its own aha-2940UW controller. Filesystem on old imap location (/var filesystem) is reiserfs, same as that on new dedicated disk.

[Dovecot] fast bind patch for ldap passwords
by Geff 03 Jan '06

03 Jan '06

All, I'm not sure if I sent this in yet or not. Basically it works like this: if you set "fast_bind = yes" it overrides auth_bind. And requires that you set userdn. Example config: fast_bind = yes userdn = cn=%u,ou=people,o=dovecot I'm using the patch right now on the cvs head branch. Comments are welcome. Geff

[Dovecot] another migration problem from courier with Outlook 2003

[Dovecot] Using dovecot auth with Postfix
by Kim Culhan 01 Jan '06

01 Jan '06

Attempting to setup smtpd auth for Postfix using the Dovecot authorization unix socket. Some info is at: http://www.postfix.org/SASL_README.html To enable operation when Postfix is chrooted, a method from the reference above is to locate the socket at: /var/spool/postfix/private/auth To do this, I have this configuration in dovecot.conf: # listener sockets will be created by Dovecot's master process using the # settings given inside the auth section auth default_with_listener { mechanisms = plain passdb passwd { } userdb pam { } socket listen { master { path = /var/spool/postfix/private/dovecot-auth-master # WARNING: Giving untrusted users access to master socket may be a # security risk, don't give too wide permissions to it! mode = 0600 # Default user/group is the one who started dovecot-auth (root) user = group = } client { path = /var/spool/postfix/private/dovecot-auth-master mode = 0660 } } } With this configuration Dovecot writes this to the log at startup: dovecot: Dec 31 17:04:32 Error: child 3536 (auth) returned error 89 dovecot: Dec 31 17:25:34 Error: Auth process died too early - shutting down dovecot: Dec 31 17:25:34 Error: auth(default_with_listener): Unknown userdb driver 'pam' (typo, or Dovecot was built without support for it? Check with dovecot --build-options) Before modifying the setup for this auth function, pam authentication was working fine. Also, Dovecot will make /auth owned by root which Postfix considers a 'fatal' problem. Should it be setup to run as user Postfix ? Any help here is vy appreciated -kim -- w8hdkim(a)gmail.com

[Dovecot] invalid mbox files
by Harout S. Hedeshian 31 Dec '05

31 Dec '05

Hello! I recently upgraded from dovecot 0.9x to 1.0.5-Aplha and now when ever folders are opened (in IMAP), it keeps saying invalid mbox files. It worked fine in 0.99.x. It is detecting the right mbox files because it lists the folders and the subscriptions correctly. I am using "default_mail_env = mbox:~/mail/:INBOX=/var/mail/%u" in the config file, but I get the same error with "Detect automatically". It generates nothing in the log files so I am lost!! I tried both outlook and thunderbird but same results. Thanks for the help, Harout S. Hedeshian

[Dovecot] 1.0alpha5: fcntl() locking problem
by Jeff A. Earickson 31 Dec '05

31 Dec '05

Hi, My setup: Solaris 9, /var/mail is NFS mounted from another Solaris 9 box, home directories and dovecot index stuff is on local ufs filesystems. I upgraded from alpha4 to a5 about 36 hours ago. Dovecot is configured like so during the build: VERSION=1.0.alpha5 CC=gcc CFLAGS="-g -O" CPPFLAGS=-I/opt/openssl/include LDFLAGS=-L/opt/openssl/lib \ ./configure --prefix=/opt/dovecot.$VERSION --with-ssl=openssl \ --with-ssldir=/opt/openssl/ssl > configure.out This afternoon dovecot basically locked up where a lot of people (including me) were getting: imap(user): fcntl() failed with mbox file /var/mail/user: No record locks available for syslog messages, and their mailbox operations would fail. In my case pine just closed the mailbox with an internal error. I did a quick fix by stopping dovecot, killing all dovecot processes, killing /usr/lib/nfs/lockd on the dovecot server, and restarting lockd. Ideas? Suggestions? Jeff Earickson Colby College

[Dovecot] Bug with userdb prefetch
by Stian Jordet 31 Dec '05

31 Dec '05

Hi, when I'm (trying) to use userdb prefetch with ldap, it works fine for system users, but for virtual users without their own uid and gid, it won't work. I get in the log: Dec 31 01:34:47 buick dovecot: auth(default): prefetch(oddrun,127.0.0.1): userdb_uid not returned Dec 31 01:34:47 buick dovecot: auth(default): prefetch(oddrun,127.0.0.1): userdb_gid not returned Which means that the problem is that user_global_uid and user_global_gid is not used when using prefetch. That must be a bug? Best regards, Stian

[Dovecot] dovecot and ldaps://
by David Coppa 31 Dec '05

31 Dec '05

Hi all, I've managed to get dovecot running with ldaps (ssl over port 636, not starttls). Btw, it's working right only if i specify "TLSVerifyClient never" in my slapd.conf. With any other parameter (like "TLSVerifyClient demand"), the bind fails with: connection_get(12) connection_get(12): got connid=0 connection_read(12): checking for input on id=0 TLS trace: SSL_accept:before/accept initialization TLS trace: SSL_accept:SSLv3 read client hello A TLS trace: SSL_accept:SSLv3 write server hello A TLS trace: SSL_accept:SSLv3 write certificate A TLS trace: SSL_accept:SSLv3 write certificate request A TLS trace: SSL_accept:SSLv3 flush data TLS trace: SSL_accept:error in SSLv3 read client certificate A TLS trace: SSL_accept:error in SSLv3 read client certificate A connection_get(12) connection_get(12): got connid=0 connection_read(12): checking for input on id=0 TLS trace: SSL3 alert write:fatal:handshake failure TLS trace: SSL_accept:error in SSLv3 read client certificate B TLS: can't accept.

Or maybe make dovecot parse the ldaprc file under /etc? Best Regards, David

[Dovecot] new user setup trouble
by Will Ling 30 Dec '05

Hi again, I am still trying to run Dovecot but persistently get the errors Corrupted transaction log file and Lost transaction log file. I cannot find any reference to this problem that will help, I have checked the file permissions and locks and cannot see any obvious cause.

[Dovecot] Dovecot index cache regeneration
by John Newman 30 Dec '05

30 Dec '05

Hi, We've been using dovecot in the lab now for quite a while and really like the results we're seeing. Underlying dovecot we're using maildir mailboxes. We have the need to manually remove maildir files from time to time. That is, by hand (we'll, actually by script) but not via imap or pop. Dues to dovecot's index caching (which I might add, we love most of the time) imap clients still continue to display the message once they're gone (as we'd expect). However, in this instance it's not what we're after. So my question is, what is the "dovecot recommended" way to force the index cache to regenerate. We really don't want to delete the entire index cache for a particular mailbox as larger mailboxes will then need to unnecessarily regenerate indices on unaffected messages. Many thanks for any tips you can provide. John.

[Dovecot] dovecot INSTALL
by Tom Lee 30 Dec '05

30 Dec '05

Hello, I just tried dovecot-stable-20051206.tar.gz. It takes me one additional day to get it work. >From INSTALL file, it failed to miss the following installation steps: 1) needs to create the file /etc/pam.d/dovecot 2) needs to create the directory /etc/ssl/certs/ and /etc/ssl/private/, configure doc/dovecot-openssl.cnf, chmod +x doc/mkcerts.sh doc/mkcerts.sh Not sure why it is not in the the file INSTALL. For pop3 client configuration, I wonder if it is OK for me to use: #outlook-no-nuls: # Outlook and Outlook Express hang if mails contain NUL characters. # This setting replaces them with 0x80 character. # oe-ns-eoh: # Outlook Express and Netscape Mail breaks if end of headers-line is # missing. This option simply sends it if it's missing. pop3_client_workarounds = outlook-no-nuls, oe-ns-eoh or dovecot can only allow one such as: pop3_client_workarounds = outlook-no-nuls Thanks. Tom

[Dovecot] LDAP authenticated bind support
by J.M. Maurer 30 Dec '05

30 Dec '05

Recently at Better.be we implemented LDAP authenticated bind support for dovecot. A patch against CVS HEAD is attached. I have not tested it against all possible configurations one can use, but the basic operation seems to be right. As documented in the patch, it adds one new option to the dovecot-ldap.conf configuration file: # Set "auth_bind" to "yes" if you want to use "authenticated binds" # as a login validation mechanism. NOTE: the pass_attrs option # will (naturally) be ignored if you enable this auth_bind = yes Authenticated bind support is implemented asynchronously. This involves 2 asynchronous calls: the first being 'ldap_search' to find the dn to bind against and the second being the actual 'ldap_bind' call. I'd love to hear some feedback on this. Regards, Marc Maurer Better.be B.V.

[Dovecot] Migrating from Courier-IMAP to Dovecot
by Andreas Mimz 27 Dec '05

27 Dec '05

Hi! I'm currently trying to migrate from courier-imapd to dovecot... Unfortunately I'm experiences some difficulties here... Since I don't want any user to notice the change of the server backend I've tried changing the namespace in dovecot.conf to namespace private { separator = . location = maildir:~/Maildir prefix = INBOX. inbox = yes hidden = no } With this setting almost everything works fine! Almost... ;-) Squirrelmail won't show 'INBOX' on the left side of the folder tree... If I configure dovecot without the 'INBOX.' prefix it works fine in Squirrelmail, except that all other eMail clients show all sub-folders as a sub-folder of root and not the inbox... root \- inbox \- sent \- trash \- drafts \- private \- spam instead of root \- inbox | \- sent | \- trash | \- drafts | \- private | \- spam any Idea what could be wrong? I've read the wiki about the courier-migration and also tried the conversion script ... but something is wrong I'm afraid... thanks in advance, Andreas

[Dovecot] inbox problems when moving from server to server
by Eric S. Johansson 27 Dec '05

this is probably an FAQ but I moved all the mailboxes from a gentoo server to an ubuntu one and all old inbox messages "disappeared" for. New messages appear and can be read, deleted etc. the old messages can still be found in the Maildir/cur directory like they were on the old mail server. Ownership was changed to user:user and is 600 permissions. Dovecot version: 0.99.14-1ubuntu1 all other mailboxes are fine, all messages visible as far as we can tell. ideas?

[Dovecot] dovecot and virtual mailbox - suggestions please
by David Bain 26 Dec '05

26 Dec '05

I've setup postfix to delivered my mail to a maildir located at /var/spool/virtual_mailboxes/mydomain.com/myuser My postgresql database called 'mails' has a user table setup as follows: CREATE TABLE users ( userid VARCHAR(128) NOT NULL, password VARCHAR(128), realname VARCHAR(128), uid INTEGER NOT NULL, gid INTEGER NOT NULL, home VARCHAR(128), mail VARCHAR(255), PRIMARY KEY (userid) ); What would the query look like in my dovecot-pgsql.conf file to retrieve the appropriate INBOX information? mine currently looks like this. user_query = SELECT '/var/spool/virtual_mailboxes/'||home AS home, uid, gid FROM users WHERE userid = '%u' The user authenticates fine via pop, yet I keeping getting the following error. -*ERR No INBOX for user*

Hi, Dovecot 1.0alpha (tested 0.99.14, 1.0alpha1, 1.0alpha4 and 1.0alpha5) does not return UID number in 'UID STORE uid-number +FLAGS (\Seen)' command response.

[Dovecot] dovecot - postgresql ERR No INBOX for user.
by David Bain 24 Dec '05

24 Dec '05

I've setup dovecot to authenticate against postgresql. But I consistently get a "No INBOX for user" error when I try to do pop requests. Any pointers would be helpful. Postfix deposits mails in maildirs in the format /var/spool/virtual_mailboxes/{domain}/{username}/ below is the result of a telnet test (altered slightly of course, but gives the idea) telnet localhost 110 Trying 127.0.0.1...

[Dovecot] Corrupted transaction log file

Hi, I am new to dovecot and have just got it up and running on mandrake 8.2. Dovecot seems to be running OK, I can telnet in and log in and Mail on OS X will get the folder list but if a client selects a mail box I get an error back.

[Dovecot] Re: PATCH: Dovecot SASL authentication for Postfix 2.3-20051220
by wietse＠porcupine.org 23 Dec '05

23 Dec '05

I'm adding the finishing touch to the Postfix Dovecot plug-in, to be released with snapshot 20051223. The plug-in code quality is generally very good. I had two observations, both of minor importance: - The authentication server protocol uses the TAB character as a delimiter, so it is critical that legitimate user names don't contain this character. This is of course trivial to ensure with the authentication server implementation, so I will not worry about it. - I noticed that the plug-in did not satisfy one Postfix principle, namely that operations be bounded in time. I added a time limit for connect, read and write operations. Postfix will time-bound all operations anyway, but the diagnostics of the watchdog timer are less specific and therefore less useful.

[Dovecot] Thinking about switching from courier-imap to Dovecot: 2 simple questions
by kadafax 23 Dec '05

23 Dec '05

Hi, I'm using RHEL4 and since the dovecot RPM is present in the main repository, I'm thinking about switching from courier-imap (with whom I've got trouble to update) to Dovecot. Here are two questions about Dovecot (google didn't answer me): 1. Is it possible for dovecot to use the bind mecanism against ldap for authentification purpose. My main concern is to avoid the clear-text password in the dovecot-ldap.conf file. With courier-imap, the process simply bind to the ldap tree with the users's supplied login/password. No need for a special authentification purpose user. 2. Does imap's dovecot implementation support folders imbrication (more than one level folders) ? Thanks, kfx.

[Dovecot] Dovecot & pam_mkhomedir
by Stroller 22 Dec '05

22 Dec '05

Hi there, Does anyone have Dovecot working correctly with pam_mkhomedir, please? I seem to be going through quite a number of IMAP servers this week, trying to find one that will not only authenticate against a Windows domain but which will also create home directories for users the first time they log in. I'm using winbind to do the authentication & that seems to be doing the trick in the first instance - if I log in using Squirrelmail I see entries written to the system log saying: Dec 16 11:58:35 baby pam_winbind[9319]: user 'ned' granted access I have set Dovecot to log to /var/log/mail and in that I see only three entries saying: imap-login: Dec 16 11:58:36 Info: Login: ned [127.0.0.1] But Squirrelmail gives: ERROR: Could not complete request. Query: SELECT "INBOX" Reason Given: /etc/pam.d/imap says: #%PAM-1.0 auth required /lib/security/pam_winbind.so account required /lib/security/pam_winbind.so session required /lib/security/pam_mkhomedir.so skel=/etc/skel umask=0022 If I use the same configuration for SSH then the user's home directory is created upon authenticaton, but not with Dovecot. I chose to try Dovecot because I understood it handled PAM session wossisnames, which Courier-IMAP doesn't. My dovecot.conf is attached - I'm wondering if the problem could be with the "auth_userdb" setting, but `getent passwd` does show an entry for the user: # grep ned /etc/passwd # getent passwd | grep ned ned:x:10012:10000:Ned Nedbody:/home/DOMAIN/ned:/bin/false # Many thanks in advance for any advice or suggestions - I'd really like to understand what's going on here. I believe I can authenticate against the domain using LDAP / Active Directory, but since I don't know if that'll help I'd rather not go that route yet. If I first try to log in using ssh with pam_mkhomedir enabled then the users' home directory is created successfully & I can subsequently log on in Squirrelmail. But it's important to me that I shouldn't have to create users' home dirs for them - I should be able to add them on the Windows domain controller & just tell them to log in to their email - the home dir on the mailserver should be created automagically when they authenticate against the domain.

[Dovecot] dovecot -CVS and epoll and cvs not building
by Reuben Farrelly 22 Dec '05

22 Dec '05

Hi, After reviewing my dovecot ./configure options I thought I'd give --with-ioloop=epoll a go again (as opposed to just using =poll) but I'm seeing some errors appearing in the maillog that aren't there with standard poll: Dec 23 02:34:47 tornado dovecot: imap-login: Login: user=<reuben>, auth-method=plain, remote=220.237.24.149, TLS Dec 23 02:34:48 tornado dovecot: imap-login: io_loop_handle_add: epoll_ctl(3, 9): No such file or directory Dec 23 02:34:48 tornado dovecot: child 16524 (login) returned error 89 They're appearing fairly frequently, ie within a few mins of starting up and then the message won't go away until the client is restarted. So it's easy to reproduce but I'm not sure how to go about debugging it. Can anyone help with this? It's a very recent Linux-2.6 system so epoll support should not be an issue. Additionally -CVS won't compile for me right now, it bails out when compiling the 'quota' plugin. Workaround is to manually edit the dovecot/src/plugins/Makefile and not build this plugin.. Timo - is there a file/commit missing from -CVS at the moment for this plugin?

[Dovecot] Migrating from mbox to maildir, which converter is compatible with dovecot
by Oliver Schulze L. 22 Dec '05

22 Dec '05

Hi, I'm testing/debuging the migration from mbox to maildir in a mailserver running Dovecot 1.0alpha5. I migrated all 472715 emails(in a test server) and later noted that dovecot could not get the same flags/status of the emails as in the mbox. I was using perfect_maildir.pl and I think its not dovecot fault. Seems to me that perfect_maildir.pl convert the emails in a way that dovecot could not understand completelly. So, my cuestion is, which mbox to maildir converter can I use that is compatible with dovecot 1.0alpha5 ? Thanks Oliver -- Oliver Schulze L. <oliver(a)samera.com.py>

[Dovecot] mailbox from ldap and indexes
by Stian Jordet 21 Dec '05

21 Dec '05

Hi, because of quota, I would like to have indexes on another filesystem then user's maildir. This I can do with "default_mail_env= maildir:/% h/Maildir:INDEX=/var/indexes/%u" or something. But when I get the users mailbox location from ldap, there is no way to set the index? I guess I can make the ldap entry contain the INDEX as well, but I would like to use the ldap entry in the exim conf as well, to tell exim where to write the mails... Is there a way I haven't thought of yet? I have this in dovecot-ldap.conf now: user_attrs = uid,homeDirectory,mailbox,uid,uidNumber,gidNumber If I could do something like: user_attrs = uid,..,"maildir:" . mailbox . ":INDEX=var/indexes/%u",... that would have been awesome. Best regards, Stian

Also, on Jeff Earickson's post, I looked at my dovecot.conf settings and they're basically default which means everything in the "Login processes" section is commented out. I have 10 users on this system and will hold off migrating any more until I can resolve this problem. By the way, my "ulimit -a" shows "open files" at 256 which seems low. # ulimit -a core file size (blocks) 0 data seg size (kbytes) unlimited file size (blocks) unlimited open files 256 pipe size (512 bytes) 10 stack size (kbytes) 8192 cpu time (seconds) unlimited max user processes 29995 virtual memory (kbytes) unlimited Any advice would be appreciated. I can't reboot for a few more days.

[Dovecot] 1.0 alpha5: Plugin woes: quota/trash
by Jan-Piet Mens 21 Dec '05

21 Dec '05

Hello, I'm running Dovecot v1.0.alpha5 and I'm trying to get the quota plugins to work. I've enabled modules in dovecot.conf, but when the IMAP connection is opened, the log shows undefined symbols. : Loading modules from directory: /usr/local/lib/dovecot/imap : dlopen(/usr/local/lib/dovecot/imap/libtrash_plugin.so) failed: /usr/local/lib/dovecot/imap/libtrash_plugin.so: undefined symbol: quota : dlopen(/usr/local/lib/dovecot/imap/libimap_quota_plugin.so) failed: /usr/local/lib/dovecot/imap/libimap_quota_plugin.so: undefined symbol: quota : dlopen(/usr/local/lib/dovecot/imap/libquota_plugin.so) failed: /usr/local/lib/dovecot/imap/libquota_plugin.so: undefined symbol: dict_transaction_commit The source shows that the modules are read by reading the module directory and loading each of the found .so files. Supposing that the ordering of the files in the directory is wrong, I've even recreated the module directory manually, copying the libs into it in different orders; no change. It seems to me as though there are cross-dependencies in the shared libs that cannot be resolved. Has anybody found it to work or could anyone give me a hint on how to get it working? Thanks & regards, -JP

[Dovecot] Auto-expunge
by John Newman 20 Dec '05

20 Dec '05

Hi, For some time we've been intermittently experiencing a problem whereby dovecot often automatically expunges "deleted" messages. This has happened across several mailboxes. The problem is proving difficult to isolate as it's seemingly non-deterministic in nature. One commonality, however, is that the "auto-expunge" seems to occur with greater frequency on mailboxes with a larger of deleted messages. First off, does this sound any alarm bells for anybody else? Perhaps others have encountered this in the past? I've trolled the mailing list (and web) but cannot find any references to this occurring elsewhere. Additional Information: We have experienced this "bug" in 1.0-alpha3 and alpha4. Underlying dovecot we have a maildir, populated via Perl's Mail::Box::Maildir module. Many thanks for any assistance that can be offered. John.

My setup: Solaris 9, dovecot built with gcc 4.0.2. Mailboxes on remote NFS file mount from another S9 box (mbox format), index files local disk. IMAP usage only. Dovecot build like so: VERSION=1.0.alpha5 CC=gcc CFLAGS="-g -O" CPPFLAGS=-I/opt/openssl/include \ LDFLAGS=-L/opt/openssl/lib \ ./configure --prefix=/opt/dovecot.$VERSION --with-ssl=openssl \ --with-ssldir=/opt/openssl/ssl > configure.out The assertion: Dec 16 14:59:54 emerald dovecot: [ID 107833 mail.error] imap(user): file message-body-search.c: line 414 (message_body_search_ctx): assertion failed: (input->v_offset == part->physical_pos + part->header_size.physical_size) Dec 16 14:59:58 emerald dovecot: [ID 107833 mail.error] imap(user): file message-body-search.c: line 414 (message_body_search_ctx): assertion failed: (input->v_offset == part->physical_pos + part->header_size.physical_size) (twice in four seconds).

If its too hard for them to setup the pop3 catch all, we can probably put some mapping in place to smtp froward mail to their server. This is more complex on our part so would prefer not to do it that way, but its an option and will require not setup on their part other than make sure their server does not accept mail for anyone other than our server. dovecot-request(a)dovecot.org wrote: > Send dovecot mailing list submissions to > dovecot(a)dovecot.org > > To subscribe or unsubscribe via the World Wide Web, visit > http://dovecot.org/cgi-bin/mailman/listinfo/dovecot > or, via email, send a message with subject or body 'help' to > dovecot-request(a)dovecot.org > > You can reach the person managing the list at > dovecot-owner(a)dovecot.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of dovecot digest..." > > > Today's Topics: > > 1.

[Dovecot] Two-phase delete/expunge ?
by Jan-Piet Mens 16 Dec '05

16 Dec '05

Is it possible to have messages which have been marked for deletion or which are to be expunged, moved into a "secret" directory on the IMAP server? The IMAP client would consider the message as deleted, but an administrator could easily restore single messages (without having to retrieve tapes) by moving the message back into inbox. I understand there are patches floating around somewhere enabling that for Cyrus, but I'd love to see Dovecot do that as well. Is anyone aware of such functionality? Thanks, -JP

[Dovecot] strange connection NG
by Yi Xuan 16 Dec '05

16 Dec '05

Dear all, I have a devocot server based on fedora core 3 in Japan. When my users are in Japan, there is no any problem reported.Devocot works very well. But when my users are in China, sometimes the following problem occured. Sometimes the user can not download mails, after that all connections attempt to server(e.g http/ssh) failed. the user has to close OutLook, and wait for about 10 minutes, then access the webmail to read mail. Maybe the POP NG is due to the network , but what is the possible reason of 10-minute other connection NG? Is there any solution? Because users in China share the same outside IP, when one user occures POP NG, all users occures server access NG, that is a big puzzle. Thanks in advance. Best regards,

Hi, I would like to submit the attached patch. It implements IO loop using FreeBSD's kqueue/kevent syscalls. It is based on snapshot of CVS HEAD as of 2005-12-12. I could only give it limited testing on FreeBSD 5.4 but it works fine so far. Vaclav Haisman

[Dovecot] 1.0alpha5 released
by Timo Sirainen 16 Dec '05

16 Dec '05

We have now some new big features: - Beginnings of dbox mailbox format. It should work, but if you happen to delete/break index files, the mails aren't found again. So really not a good idea to use it for more than testing. - GSSAPI (Kerberos 5) support by Jelmer Vernooij with some fixes by pod(a)herald.ox.ac.uk - Added dictionary API to Dovecot, similar to what Postfix has. It can be used for getting/setting key=value pairs, which can be useful for many different purposes. For example it could be used to store mailbox metadata for ANNOTATEMORE extension. Implemented SQL backend for it. In future there should be berkeley DB backend at least. Also there could be some kind of proxy backend which would use UNIX socket to connect to dictionary server doing the actual work. This way each imap/lda process wouldn't have to connect to SQL server themself. - Quota plugin is now included. We also have now dictionary based quota support, which means the quota limits and values can be stored in SQL. However I haven't actually tested these changes yet, so there's a good chance the quota plugin doesn't actually work at all. - Created a new trash plugin which works only together with quota plugin. The point of it is to expunge mails from a list of configurable mailboxes whenever saving new mails would cause the account to go over quota. The oldest mails are expunged first, and only as many mails are expunged as is needed to save the new mail. For configuration it first looks up for ~/.dovecot.trash.conf, and then fallbacks to /etc/dovecot-trash.conf. The file format is "<priority> <mailbox name>". It's possible to have multiple mailboxes with same priority. Lower number = higher priority. This plugin is also currently untested. The plugins are currently installed as shared libraries to plugin directory. At some point I'll add a configure option to select which plugins to compile directly into binaries. Possibly even do it by default for some plugins (quota). And smaller new features: - If LDAP lookup fails because connection gets closed, try retrying it again after reconnect. This is however untested, hopefully didn't break LDAP code completely.. - %w variable in dovecot-auth contains password. Can be used to do eg.: password_query = select null as password from users where userid = '%u' and password = password('%w') - syslog_facility setting And fixes: - auth_cache was quite broken - adding keywords caused sometimes assert-crash - If login_greeting_capability = yes we could have sent the capability before dovecot-auth returned what auth mechanisms were available, forcing clients to use plaintext authentication - Lots of mbox fixes again.. - userdb prefetch wasn't supposed to be uncommented in dovecot-example.conf in alpha4. Comment it out if you don't need it. - Don't crash with "out of memory" in 64bit systems - IDLE command might have crashed when finishing itself if there were lots of external changes - pop3_reuse_xuidl setting wasn't actually working

[Dovecot] messages_count too large (1121 > 1115)
by Moritz Willers 16 Dec '05

16 Dec '05

I've seen this was mentioned before but remains unsolved. I upgraded Dovecot from 0.99 to v1.0.alpha4 yesterday and it rendered my inbox inaccessible: Dec 15 00:09:07 sand dovecot: imap(willers): Corrupted index file /home/willers/mail/.imap/INBOX/dovecot.index: messages_count too large (1121 > 1115) I've since moved that inbox away so I can view my new mail again. The error has moved with the mbox file: Dec 15 00:27:41 sand dovecot: imap(willers): Corrupted index file /home/willers/mail/old-inbox/.imap/200407-200512/dovecot.index: messages_count too large (1121 > 1115) Dec 15 00:27:41 sand dovecot: child 83886 (imap) killed with signal 11 This is on FreeBSD 4.8 (yes, yes ... but: "up 687 days" which is quite nice) all running on local disk. So earlier suspicions about NFS or MacOS X are out of the window. One day I'll move move from mbox to dir format and the problem will go away, in the meanwhile, I thought it would be good to resolve this issue. Let me know how I can help to get to the bottom of this. - mo

[Dovecot] Variable '%r' doesn't transfomr in Postgres query

Hi, i'm using postgres for authorization. When I switched from a4 to a5 authorization stoped working. Query in conf file for postgres looks like this: password_query = select password from auth('%u','%r'); But in logs, the transformed query looks like this: Performing query: select password from auth('test','%r'); Looks like you don't transform that remote IP parameter?

[Dovecot] writing an MDA, help me avoid corrupted indexes
by Lee Howard 15 Dec '05

15 Dec '05

Hello. First, I want to thank those responsible for Dovecot IMAP as it was a real treat to implement in comparison to my mostly-failed attempts with Cyrus. The passwd-file authentication was exactly what I needed as I really didn't want to have to deal with PAM or LDAP but where I am setting up a server with virtual accounts. I'm using Postfix as an MTA, and it quite handily passes the mail off to SpamAssassin. From there I need an MDA to dump any mails detected as spam into a common spam folder, discard any mails with viruses (antivir) and send a notification to me, and then drop good mail into the appropriate maildir directory for the virtual users to get via both POP3 and IMAP. I could conceivably use procmail to do that MDA, and I've done similar things with procmail in the past, but my growing experience with procmail indicates that procmail is too ferocious for what simple work I need done, and too difficult to make work right in a virtual-user environment. So I've written my own little MDA with a few lines of shell that will take the mail from Postfix+SpamAssassin and ultimately deposit mails in the maildirs. So far so good, except that I keep seeing corrupt indexes... probably because I'm not touching the indexes at all with the MDA. My guess is that in order for the MDA to properly deal with maildir it needs to adjust the indexes after depositing new mail. Okay. So can someone either give me a pointer to the proper documentation on this, including the index file formats, or perhaps just explain it to me? Maybe I'm missing a larger picture of maildir handling? I've glanced through http://www.dovecot.org/doc/index.txt but I notice that the index files are not ASCII, so I'm not sure where to start at understanding that documentation. Any and all help would be appreciated. Thanks, Lee.

[Dovecot] How to serve two "inboxes" via imap
by Roderick Johnstone 15 Dec '05

15 Dec '05

Hi In our setup we have mail delivered to /var/spool/mail/<username>. Many users like thunderbird as their MUA and we typically have thunderbird set up to read mail using a movemail account with the local mail directory set to ~/mail so that the mail can be read easily by pine as well. So, when a user clicks the "Get Mail" button in Thunderbird, mail is moved from /var/spool/mail/<username> to ~/mail/Inbox. Although I can serve other folders from ~/mail my imap clients don't see ~/mail/Inbox, they see just /var/spool/mail/<username> as INBOX. Can anyone advise please how to make the ~/mail/Inbox available as well via imap using dovecot (currently using 1.0-alpha5). We currently use default_mail_env = mbox:~/mail/:INBOX=/var/spool/mail/%u Many thanks Roderick Johnstone

[Dovecot] checkpassword authentication
by Florian Füessl 14 Dec '05

14 Dec '05

Hi, does anyone already use the checkpassword authentication scheme? I have not found any description how I have to configure dovecot in order to work together with qmails checkpassword. Enabling passdb = checkpassword /bin/checkpassword in dovecot.conf starts /bin/checkpassword for every authentication request, but the result does not seem to matter for the authentication. Without enabling a userdb entry, dovecot claims not to be able to find out the uid, gid and home of the user, although checkpassword replies these values. Setting static values with "userdb = static uid=$fixed_mail_uid gid=$fixed_mail_gid home=/maildata/%d/%n" results in being every login successful, no matter if the checkpassword authentication is ok, or not. I'm using the latest dovecot nightly build from 22. Nov. 2005. - Florian

Lines of ssl in /etc/dovecot.conf protocols = imaps pop3s imaps_listen = * pop3s_listen = * ssl_disable = no ssl_cert_file = /usr/share/ssl/certs/dovecot.pem ssl_key_file = /usr/share/ssl/private/dovecot.pem ssl_parameters_file = /var/run/dovecot/ssl-parameters.dat disable_plaintext_auth = yes If i do telnet localhost 993 or 995 I don't see any "Ok Dovecot Ready" message.If I enable pop3 and imap in dovecot.conf and then I telnet localhost 110 or 143 I can see "Ok Dovecot Ready" message. Any pointers what else I am missing for ssl in dovecot and I am also attaching the dovecot.conf file with this email. Thanks & Regards Ankush Grover

[Dovecot] Hi everyone .. need some pro-dovecot arguments :-)
by Florian Schnabel 13 Dec '05

13 Dec '05

Hi, i never used dovecot so far, but i heard a couple good things about it .. for one the debian maintainer of the exim package recommended it :-) so i want to change our mailserver (currently using ipop3 and uw-imap) to dovecot ... now my boss seems to favour cyrus. i could use some good arguments for dovecot, also your experiences with it and with other mailservers so i can make a reasonable desicion and preset some good arguments :-) Florian

I'm trying to switch to imap from pop3, so I set up dovecot on my Slackware 10.2 mailserver. I'm very new to imap, so I figured my configuration was wrong. If our symptoms are the same, maybe our setup errors are as well. The problem... while Thunderbird and Outlook are OK, the Inbox doesn't show in Outlook Express. You can click on the Imap Folders button, select the Inbox, click on the "Go To" button and the Inbox will appear until you shut down Outlook Express. Next time you fire up OE, no Inbox. Other than that, it all works as expected. I haven't torture-tested the setup yet though, I wanted to set up one of each client and get the basics running before doing that. Are your symptoms similar? Here is my dovecot.conf less comments... ssl_cert_file = /etc/mail/certs/wally.cert.pem ssl_key_file = /etc/mail/certs/wally.key.pem first_valid_gid = 100 mail_extra_groups = "mail" namespace private { separator = / inbox = yes prefix = "#mbox/" location = mbox:/var/spool/mail/%u } namespace private { separator = / prefix = location = maildir:/data/imap/%u } protocol imap { imap_client_workarounds = outlook-idle } protocol pop3 { } auth_realms = "laframboise.net" auth default { mechanisms = plain passdb shadow { } userdb passwd { } userdb prefetch { } user = root }

[Dovecot] mailserver pop3-login: Disconnected
by Shawn Bishop 13 Dec '05

13 Dec '05

Good Day I am having the following serious problem. I am running CentOS 4.1 with dovecot 0.99.11. The users are using POP3 login to retrieve mail. For the last 2 days we have experienced the following problems. I have recreated all the users and reconfigured the dovecot,but the same problems occur. Please see attached /var/log/maillog messages It appears so users login whereas others cant.Eventually after about an hour none of the users can login.

[Dovecot] Case sensitive nightmare

12 Dec '05

It took me 4 days to figure this out and I sure hope someone can help me solve it. My Setup: Postfix + MySQL + dovecot dovecot.conf: default_mail_env = maildir:/var/spool/vmail/%d/%n/Maildir password_query = SELECT password FROM mailbox WHERE username='%u' user_query = SELECT maildir, 108 AS uid, 108 AS gid FROM mailbox WHERE username='%u' The virtual host schema is postfix.admin compatible but I¹m not using it (phpMyAdmin is actually easier to use). When foo(a)domain.tld, abrand new account, logs in using an IMAP client (any client; squirrelmail, OE, tbird, Apple...) a maildir is created named domain.tld/foo/Maildir¹ and everything is good. Now I login as Foo(a)domain.tld and then as fOo(a)domain.tld and then as foO(a)domain.tld then so on for every case variation. Each of these accounts can login correctly, they are seen as being the same account by dovecot. On the other hand they are not seen as being the same mailbox! When I check my mail spool I see one maildir for every case variation (domain.tld/foo/Maildir, domain.tld/FOO/Maildir, etc.) It would seem to me that the queries above would fail for the different variations of the name but they don¹t seem to. Is dovecot converting %u to lower case for the query on the virtual users table but then using it unconverted when looking up the Mairdir for the account? If the username column has the value foo(a)domain.tld1 how does SELECT * FROM table WHERE username=¹FOO(a)domain.tld1 match the row? Also puzzling is that I select a column named maildir which has the path to the mailbox in it (using the correct case). Even if SELECT pigs fly¹ AS when WHERE FoO¹=¹foo¹ the maildir path for the account is being returned which is domain.tld/foo/Maildir¹ so how does domain.tld/FoO/Maildir¹ get created? This is both a pain in the nuts support nightmare but also a security problem (albeit fairly limited). An account named ³barneyrubble² could generate a significant number of maildir directories if you logged in with every variation thereof. Any assistance would be greatly appreciated. Thanks

hey friends, I am trying to secure my mail server.I have enabled TLS support in postfix(version postfix-2.1.5), now I am trying to configure squirrelmail(version 1.4.4-1 rpm) for tls/ssl support.In config.php i have choosen use_imap_tls=true and use_smpt_tls=true.

[Dovecot] Corrupted index problem when disk quota exceeded
by Sergey Redin 11 Dec '05

11 Dec '05

Hi! I should report yet another problem with dovecot index files. Suppose we have a user with his filesystem disk quota exceeded. He logins via POP3 or IMAP to remove some mail messages and fix this problem. When he logins for the first time, everything works fine, and he can read and remove something. But if his disk quota is still exceeded when he logs out, he cannot login any more. I guess it is not fair to give user only one chance to clean his mail folders :) The problem is that dovecot tries to rewrite index files on logout, but it cannot do it correctly because the user's filesystem quota is exceeded. So the next time dovecot just replies "Mailbox is in inconsistent state, please relogin". I believe that dovecot should work with any kind of corrupted index files, this is why I report such kind of bugs here. Here is a sample session with dovecot which shows the problem: ======================================== dovtest# telnet localhost pop3 Trying ::1... Trying 127.0.0.1... Connected to localhost.

[Dovecot] openssl > 0.9.f-4 a must for dovecot 0.99.14 ??
by Adrian Mak 10 Dec '05

10 Dec '05

My linux is Redhat AS3 U3, openssl is 0.9.7a-33 I downloaded dovecot 0.99.14 src rpm and rebuild to binary rpm Everything went smooth but I tried to install the dovecot binary rpm, it reported that openssl need >= 0.9.7f-4 Since there are many other rpm packages have dependency on the current version of openssl 0.9.7a-33, so It's not possible to upgrade openssl to 0.9.7f-4 or greater Is it a must to use openssl 0.9.7f-4 or greater in order to use dovecot 0.99.14 ?

[Dovecot] Order of emails
by Marcus Don 10 Dec '05

10 Dec '05

Hi We have an issue regarding the order in which emails are displayed in an imap folder, which our customers regularly complain about. By default, emails are returned from a folder in the order in which they were placed into the folder, which makes perfect sense. However, if an email is moved into another folder, it will always appear at the top, no matter how old it is. We could order the emails ourselves before displaying them in our webmail program. However, this would mean parsing the headers of every single email, which could be many thousands, so would slow things down considerably and greatly increase load. At the moment, we only read 30 at a time as the user pages through the folder. >From what I can see, the order is determined by the timestamp in the email filename, which gets updated every time the email is moved. Is there any way we could disable this, so the filename (or at least the timestamp part of it) remains constant? If so, would this affect in any way the behaviour of other imap clients, such as Outlook? All suggestions welcome.

[Dovecot] Squirrelmail/dovecot sort problem/bug
by A.P.Munnikes 10 Dec '05

10 Dec '05

Hello, there is a little bug in Squirrelmail 1.4.5 or Dovecot 1.0.alpha4-1: the sort is not correct if I use squirrelmail with the option: 10. Allow server thread sort : true 11. Allow server-side sorting : true with the option on false and with Thunderbird 1.5rc1 there is no problem, but I think Thunderbird 1.5rc1 already does the sort by itself. I have a folder with 1054 messages, but if I sort (from old to new) them in squirrelmail the newest 3 messages (received after the migration from thunderbird/pop3 to dovecot) are on the first page, before the messages from 5 month ago. 14:08 3.4 k (that is today 8 dec, 2005 ) 08:26 5.2 k + 00:07 2.9 k 8 jul, 2005 4.1 k 6 jul, 2005 3.5 k 3 jul, 2005 3.1 k 8 jul, 2005 4.1 k 6 jul, 2005 3.3 k 8 jul, 2005 3.8 k 5 jul, 2005 4 k 8 jul, 2005 7.4 k 11 jul, 2005 6.8 k Also my 'sent' folder: sorted from new to old contains on the last page 2 messaged that I send today (after the migration to dovecot) 12 jan, 2005 2.8 k 12 jan, 2005 1.7 k 11 jan, 2005 1.5 k 10 jan, 2005 1.1 k 8 dec, 2005 1.1 k ( <= send from thunderbird) 8 dec, 2005 1.6 k ( <= send from squirrelmail) And also an other mail folder has sorting problems. However my INBOX looks normal, while I received 5 or 6 messages after the migration. What have I done: *restarted apache2 a couple of times *restarted dovecot a couple of times *In the first folder (with >1000 messages) I already have deleted the dovecot files and new files are generated -rw------- 1 alfred alfred 17184 2005-12-08 23:41 dovecot.index -rw------- 1 alfred alfred 60416 2005-12-08 23:42 dovecot.index.cache -rw------- 1 alfred alfred 17908 2005-12-08 23:42 dovecot.index.log -rw------- 1 alfred alfred 10 2005-12-08 21:15 dovecot-keywords -rw------- 1 alfred alfred 40600 2005-12-08 23:41 dovecot-uidlist *closed webbrowser and restarted a new firefox 1.5 and surfed to squirrelmail.

[Dovecot] Update on Using Dovecot with Webmin
by Lee MSN 10 Dec '05

10 Dec '05

First of all thanks for the replies. I have decided to try the updated version 1.0 alpha After uninstalling Dovecot .99 and cleaning up user,groups and files. (Dovecot .99 was authenticating as best I can tell using unix users = the default -- and PAM = the default - I only had to setup the PAM if I remember correctly. Loaded Dovecot 1.0, made sure user, folders and files all seem to be setup correctly. Now - Webmin is able to stop and start Dovecot and it loads fine on reboot. But, it is pretty obvious that the Webmin modual is not up with then new and much more powerful Dovecot config file. For me that is OK, as long it will show weather the service is up or down - stop and start it, which is seems to be doing just fine. The reason I say this is when I try and use the Webmin modual to set user authentication to Standard Unix user database and PAM - it does not work. So I am needing help editing the Dovecot.conf file. My new problem is this: Can not get users to authenticate. I am trying to first setup just unix authentication - with plain text for starters then will move up to more secure. I have left the config file default - just made changes until it would start. With the notable execption I set plain text to yes. I have setup the Dovecot PAM file per the documentation. So what I need help now with is this I am wanting to setup a very simple setup to start with: A setup so that a outlook express client can login, using plain text password, unix login and password POP3 = yes Users = linux/unix (/etc/passwd) Passwords = PAM or Shadow Can anyone send me and edited config file that is setup to for this type of authentication? Or cut from their config file those sections needed for the authentication? Actually, if anyone is willing to share a config file that is setup with a more secure type of authentication that would be great too. (Thinking of switching to Cyrus - have any of you jump off of Cyrus to use Dovecot -- why??)

[Dovecot] Dovecot out of memory errors on Debian sid
by Ric 10 Dec '05

10 Dec '05

hi I have dovecot (1.0.alpha4-1) installed on a Debian sid amd64 machine (dovecot-imapd and dovecot-common). I am using this so that I can use both Mutt and something like Thunderbird to access my local Maildir folders. Sometimes it works fine. Sometimes when I try to access my mailboxes locally using Mutt, it hangs for a very long time (the bottom of the screen says "Selecting in..." (.in is the mailbox), and eventually gives me a blank mailbox with "(no mailbox)" at the bottom of the screen. In /var/log/mail.err I find lines like the following: Dec 3 06:39:02 localhost dovecot: child 4600 (imap) returned error 83 (Out of memory) Dec 3 06:44:03 localhost dovecot: imap(ric): pool_system_malloc(): Out of memory For example, it was working fine earlier this morning, but now I am unable to access the mailboxes and I'm getting the error messages in /var/log/mail.err. I have the same problem with Thunderbird; it hangs and cannot access the mailboxes. At my office I have dovecot (0.99.14-1) installed on a Debian sarge machine and it works fine. I would appreciate any suggestions as to what to try or what to look for. My dovecot.conf file is very simple: ## Dovecot 1.0 configuration file protocols = imap listen = localhost ssl_disable = yes log_timestamp = "%Y-%m-%d %H:%M:%S " mail_extra_groups = mail protocol imap { } protocol pop3 { } auth default { mechanisms = plain passdb pam { } userdb passwd { } userdb prefetch { } user = root } Thanks, Ric

[Dovecot] "Out of memory" error in 1.0alpha3
by Sergey A. Lipnevich 10 Dec '05

10 Dec '05

Hi All, I have Dovecot 1.0 Alpha3 running on x86_64 Linux 2.6 multi-CPU box using Maildir folders. Moving messages from one folder to another in Thunderbird 1.0.7, regardless of their size (usually small), produced error 83, "Out of memory", when both of these parameters were unset (default): mail_read_mmaped, mmap_disable. The log line before the error was pool_system_malloc(): Out of memory. I initially changed mmap_disable to "yes", the error stopped, but it still wasn't moving messages reliably. I then set MM parameters more aggressively: mail_read_mmaped = yes, mmap_disable = no (and the third of the series, mmap_no_write, is left unset). The error stopped popping up, and the moving works speedily. Maybe the default for mail_read_mmaped should be "yes?" Thank you! Sergey.

[Dovecot] yet another update of the Dovecot AUTH patch: 20051208
by /dev/rob0 09 Dec '05

09 Dec '05

Wietse won't sit still ... removal of the lmtp(8) client broke the previous issue of the revised Dovecot AUTH patch. So I just redid it for the 20051208 snapshot: http://www.nodns4.us/postfix-2.3-20051208-dovecot-auth.patch.gz $ md5sum *gz ; ls -l $_ 32946afa424b3fbc04c8d9822e711e1f postfix-2.3-20051208-dovecot.patch.gz -rw-r--r-- 1 rob0 console 7287 2005-12-09 17:09 postfix-2.3-20051208-dovecot.patch.gz The original patch is here: http://dovecot.org/patches/postfix/postfix-2.2.1-dovecot-auth.patch Instructions are here (and don't forget the Postfix SASL_README too): http://dovecot.org/patches/postfix/README NB: Although my own postfix-2.3-20051208 snapshot compiled with the patch and is running, it is not tested at all. I'll try with AUTH later and see if it's working. I will not be able to test with LMTP. IIUC how this patch affects LMTP, it's only in that the USE_SASL_AUTH flag was changed to USE_SASL_CLIENT_AUTH. So the only people affected would be ones who are using Cyrus-SASL for client AUTH. Please let me know via either list (or offlist, see .sig) if you use this and have any problems. -- mail to this address is discarded unless "/dev/rob0" or "not-spam" is in Subject: header

[Dovecot] Controlling Dovecot with Webmin
by Lee MSN 08 Dec '05

08 Dec '05

Dear Sir I have just setup a Fedora 4SE server, with Webmin - latest production release and Dovecot .99.14. The only way to start dovecot is to be logged into the server as root - locally or ssh, and type the dovecot command. >From Webmin - logged in as ROOT, when I attempt to start Dovecot it tells me that it can't because it can not open the config file - permission denied. This indicates to me that Webmin is not really logged in a "root" but that doesn't seem right since I use root/password when I access the server per the Webmin instructions. Also, in the Webmin configuration for that server - it references a master.pid file. Which did not exist. I tried to create a pid file using the PID (19638) of the Dovecot service. That did not help the start up problem, but I am sure needs to be fixed before I can have the service start on boot up?? I got the PID number after starting Dovecot and then going and seeing the services that where then running. The user/group Dovecot where created during the install. Sendmail is running along with SpamAssassign. When I start Dovecot, logged in as root at shell, everything runs well, email is processed all the way through. Do you know how to resolve this problem of controlling Dovecot through Webmin and making sure the Dovecot will start on reboot of the server. Thank you very much. Lee D. I am new to setting up linux servers like this. _________________________________________________________________ Express yourself instantly with MSN Messenger!

[Dovecot] Dovecot login hangs often
by P P Anwar 08 Dec '05

08 Dec '05

Hi - We have dovecot version : 0.99.11 release : 2.EL4.1 on Centos 4.2, with an LDAP backend (Samba PDC) and pam set to authenticate against LDAP. Dovecot is set to use pam for authentication. It uses mbox, and the machine has very little load (95% idle, no memory pressure). Every 36 hours or so, no users are able to login to imap (we have only imap enabled). Other services that use the same backend are working fine (like squid and ssh logins) even while this is happening. So we are not sure if we can blame this on pam/ldap problems. When this happens, we tried a "service dovecot restart", and that results in saying the "address is in use". About 10 "imap-login" processes seem to lurk around holding on to the imap port. We can get dovecot service to start again, only after a "killall -9 imap-login". What kind of debug should we enable so that you all can diagnose this further ? Any other configuration things that we should try ? We prefer to stay with Redhat/Centos releases, but if this is already reportedly fixed in one of the later builds, we are open to trying one. Regards, Anwar.

[Dovecot] "pop before smtp" dovecot.conf
by Jean-Marc Pigeon 07 Dec '05

07 Dec '05

Bonjour a Tous, I would like to generate (on the fly) a list "popbeforesmtp" when dovecot POP/IMAP authentication succeed. Intended Format will/should be such as: 'timestamp_in_second' user_id remote_ip one user per line. My guess we have all the needed information within dovecot to make such list. But I have seen no way to 'trick' dovecot (dovecot-1.0.alpha3) to do it... Could someone on the list able to give me some advices? I know there is Perl script to scan maillog file and extract information from collected data, but this seem to me 'a kind of the very last option'.... May be the trick can be achieved using 'executable' function? Ideally I'll like to have an entry in dovecot.conf, like... popbeforesmtp=/somewhere/in/the/tree A bientot -- ========================================================================== Jean-Marc Pigeon Internet: Jean-Marc.Pigeon(a)safe.ca SAFE Inc.

[Dovecot] Pop-before-smtp and MySQL?
by Matteo Garofano 07 Dec '05

07 Dec '05

Hi, I found that dovecot have many nice features. Now I write because I'm tring to setup the dovecot server, I would substitute a qpopper daemon (patched for mysql authentication) The problem I find is to set up the pop-before-smtp using sql (mysq) as written in http://wiki.dovecot.org/moin.cgi/PopBSMTPAndDovecot (Waiting for post_login ;-) I would use the script popbsmtp.sh and not a perl pig. (I'm using qpopper patched to store the relay IP in mysql and it works) I set .my.cnf in /root What happen is that the $3 don't contain the IP that should be written to the DB. Is there something I miss ? I tried to modify the dovecot.conf file like this mail_executable = /usr/local/libexec/dovecot/popbsmtp.sh /usr/local/libexec/dovecot/pop3 %r "%r" and it write to the db the litteral value %r and not the ip, otherwise it write nothing. the connection with mysql works and any other operation on it works. this should be the last step for my setting. Have you any hint? Thanks in advance and best regards Matteo Garofano

[Dovecot] Tools to analyze status/stats?
by wolff 07 Dec '05

07 Dec '05

Hello, I recently installed dovecot on a server running Debian. I only have 10 users, but we probably have 6Gig of email between us. Things were working flawlessly for a couple of weeks, and I'm still getting email, but the last few days we are getting fewer emails that we typically do. So although things seem to be working well, everyone is suspicious something is wrong due to the lack of email volume. Is there a size limit that dovecot can manage? Are there any admin tools to get status messages for dovecot? Are there any reporting tools to show how many messages are processed/managed by dovecot? Thanks!!

[Dovecot] 1.0alpha4: pop3_reuse_xuidl patch
by grant beattie 06 Dec '05

06 Dec '05

hi all, this is needed to make the pop3_reuse_xuidl option work in 1.0alpha4. I am using maildir and I noticed that for each message which doesn't have an indexed X-UIDL header, the entire message is read from disk. as this is reading only headers, it is probably reasonable to stop reading at the end of the headers. it would also be neat if dovecot could be configured to only try reading X-UIDL headers from messages if the mailbox indexes don't exist, since I guess it would be common to want to preserve existing X-UIDLs but not bother for new messages (perhaps some mtime comparison, or something). opinions? I haven't looked at the source enough yet to be able to do this, but these two optimizations would vastly reduce the amount of disk IO as a result of using this option. grant.

[Dovecot] Struggling with namespaces...
by Kev Latimer 06 Dec '05

06 Dec '05

Hi all, I've been using dovecot 0.99x as a basic POP3/IMAP server at a couple of sites for a few months now and am very happy with it's simplicity, stability and performance, especially over the rather 'clunky' courier and the mammoth cyrus. I'm building up a top level mail server for our organisation and am desperate to use dovecot in there but I'm really struggling with using namespaces to create some shared maildirs - note that in this case I'm using the 1.0alpha4 debian packages that recently made it into 'etch'. I have very simple requirements here - I just want to be able to have some common folders subscribable by certain users, for my testing an announcements folder accessible by all and an archive folder I want to place some restrictions on. Whenever someone needs access to someone elses folder (ie. holiday watch), symlinking should be sufficient. I can start up dovecot, log in as a user (I authenticate against LDAP btw), see the directories specified in my namespace directives be created but I can't subscribe to anything. Squirrelmail gives an error stating "[TRYCREATE] Mailbox doesn't exist: archives" while Thunderbird shows the folder names in grey and refuses to subscribe. Am I missing the point of namespaces or have I failed to create something in the folders to get them to play? I read something about a dovecot-shared file but I think this is a 0.99 thing, although I tried creating the file with the permissions I wanted applied to the folder and it didn't do anything... I did notice that when the folders are created, they are created owned by the first user logged in. I have tried chmod'ing them to 777 to see if it makes a difference, but alas, no. The relevant bit of dovecot.conf is: namespace private { separator = / #prefix = #location = inbox = yes #hidden = yes } namespace public { separator = / prefix = announcements/ location = maildir:/var/mail/announcements/Maildir } namespace shared { separator = / prefix = archives/ location = maildir:/var/mail/archives/Maildir } I'm sure I'm just being picky, but a better explanation of namespaces in the docs might be in order, maybe with some examples. If I get this sussed out, I'll put one in the wiki ;) Any help much appreciated! Kev

[Dovecot] 1.0.alpha4 process creation wierdness
by Mark Rosenstand 06 Dec '05

06 Dec '05

Hi list! I'm a little confused. I have set "login_process_per_connection = yes" and "login_processes_count = 1", and this is how my pstree looks when nobody is connected: dovecot -,- dovecot-auth `- imap-login However, when I connect with a client it looks like this: dovecot -,- dovecot-auth |- imap `- 2*[imap-login] I would expect it to only have one imap-login running. Anyway, when I disconnect the client, the imap process exits but imap-login keeps running: dovecot -,- dovecot-auth `- 2*[imap-login] This is when it gets really wierd. When I connect a client again, my pstree looks like I would have expected it to on my first connect: dovecot -,- dovecot-auth |- imap `- imap-login If I re-connect, we start over again (i.e. dovecot-auth, imap, 2 * imap-login). Anybody got a clue what's going on? :-) -- .-. Mark Rosenstand (-.) oo| cc ) /`'\ (+45) 255 31337 3-n-( (\_;/) mark(a)borkware.net _(|/`->

[Dovecot] Feature/bug starting from xinetd
by Geoffrey S. Mendelson 06 Dec '05

06 Dec '05

Hi, I hate to have my first post be a bug, but this drove me crazy for a while. I compiled the latest version from source and followed the instalation instructions. I then copied the xinetd.d entries from the Wiki and proceded to test. No matter what I did I could not log on. I found that while I was editing /usr/local/etc/dovecot.conf, nothing was hapening. I then started it manualy and found several errors in my editing. :-) After fixing the errors and getting it to work properly, I went back to running it from xinetd. It would not allow me to log on, nor would it use any of the loging options I set. After making a symlink from /usr/local/etc/dovecot.conf to /etc/dovecot.conf, it worked perfectly. My suggestions: 1. Change the Wiki to point out the difference in the config file location. 2. Change the inetd version to default to /usr/local/etc. 3. Add (and/or document) an option to the inetd version to specify config file location. Thanks, Geoff. ( A very happy Dovecot user, thanks for a good product). -- Geoffrey S.

[Dovecot] New Install Assistance
by Cliff Hayes 06 Dec '05

06 Dec '05

Hello, I built a Fedora 4 sendmail server to replace our old one. I wanted to try the stock Dovecot popper (we currently use pop3d). I tried implementing Dovecot this morning and failed. All I want to use is the POP portion (no IMAP). From what I could find on the Internet, all I had to do is change dovecot.conf protocols line to read like this: protocols = pop3 Apparently, that wasn't enough. Here are the errors I saw in maillog: Oct 31 07:54:23 sendmail dovecot: child 25511 (pop3) returned error 89 Oct 31 07:54:24 sendmail pop3(cliffhayes): mbox: Can't create root IMAP folder /home/cliffhayes/mail: Permission denied Oct 31 07:54:24 sendmail pop3(cliffhayes): MAIL environment missing and autodetection failed (home /home/cliffhayes) Now, I did find out that I had a permissions problem with /var/spool/mail (I had done an SCP of all our users to var/spool/mail on new box). All user mailboxes had root/root as user/group. I know how to fix that for next time, but why is it trying to use a home directory (we don't use those)? And what MAIL environment is missing? Do I need to mess with the following settings: # default_mail_env = maildir:/var/mail/%1u/%u/Maildir # default_mail_env = mbox:~/mail/:INBOX=/var/mail/%u # default_mail_env = mbox:/var/mail/%d/%n/:INDEX=/var/indexes/%d/%n Thanks, Cliff

[Dovecot] Dovecot and loadbalancer
by Cyril Feraudet 06 Dec '05

06 Dec '05

Hi all, I've 4 servers with dovecot and ldap authentication behind a loadbalancer (Alteon). To connect to dovecot, client need to use a vip of the loadbalancer. To connect to the ldap server, dovecot need to use the loadbalancer cause there are several ldap server. The loadbalancer close a connection without activity during 30mn Dovecot lauch several authentication process who have a connection to the ldap server each. Each client (user) have several imap connection to dovecot. I've 2 problemes : - If a client (thunderbird for ex.) don't use a connection during 30mn, the loadbalancer delete this connection from his connection table and the client seem not able to correctly reopen another - If a dovecot authentication proccess want to request ldap but haven't do it in the last 30mn, it fail an say that the authentification fail. Somebody have already use dovecot in a redundent environnement ? Have you an idea to solve these problems Thanks, Cyril Feraudet

[Dovecot] New mailbox format
by Timo Sirainen 06 Dec '05

06 Dec '05

I've been doing some thinking on a new better mailbox format that'd be faster than mbox and maildir for most common uses. Comments welcome. It won't come to Dovecot v1.0, but I'll probably create another branch to Dovecot CVS where I'll start implementing it and some other possibly destabilizing changes. Generic ------- The point is to have a mailbox format where the mailbox can consist of one or more files. Grouping multiple files in a single file makes it faster to read, but it's slower to expunge mails from the beginning of the file. So this format would allow sysadmin to specify rules on how large the files would be allowed to grow. This format is mostly designed to work nicely with separate index files such as Dovecot has. The flags are stored in the mailbox files mostly as a backup in case the index gets lost or corrupted. Index File ---------- Named "index". Index file gives a mapping between UIDs <-> filenames: Header: <uidvalidity> <last-used-uid> Record: <uid-first> <uid-last> <filename> Record: .. eg.: 1127468129 5 1 3 msg.1 4 4 msg.4 All of the UIDs don't have to actually exist in the file if they have been expunged. The record should be removed once all of the UIDs have been removed from it (and the file itself been deleted). The same file may appear multiple times in the index. For example: 1 2 msg.1 3 3 msg.3 4 5 msg.1 This means that UIDs 1, 2, 4 and 5 are in file msg.1, but UID 3 is in file msg.3. The filename doesn't matter as long as it's unique, but probably wouldn't hurt to include its first UID in the filename so humans can find mails more easily. The filename however must not end with ".lock". The file is modified by creating first exclusively owned "index.lock" file, updating it and then rename()ing it over the index file. This lock file shouldn't be held for a long time, so if it exists, and it doesn't get modified at all within 30 seconds, it can be overwritten. Before rename()ing over the index file, you should check with stat() that the index.lock file is still the same as you expect it to be (in case your process was temporarily stopped for over 30 secs). The index file's mtime timestamp must grow after each modification. This makes it easy to check if new mail has been added to the mailbox. Mail File --------- File header: Bytes Format Description 8 hex Header size 16 hex Append offset 4 hex Mail header size 4 hex Mail header padding 4 hex Keyword count in mail headers Mail header: Bytes Format Description 8 hex UID 16 hex Mail size 1 1/0 Answered flag 1 1/0 Flagged flag 1 1/0 Deleted flag 1 1/0 Seen flag 1 1/0 Draft flag 1 1/0 Expunged flag n 1/0 Keywords The file layout then goes: <File header> - possible padding due to Header size <Mail header #1> - possible padding due to Mail header size <Mail data #1> - possible padding due to Mail header padding (ie. next Mail header's offset is divisible with Mail header padding) <Mail header #2> etc.. The UIDs must be ascending within the file (but as said above, some UIDs between them may exist in other files). When the file is opened, it must be shared locked with flock(). Expunging mails requires exclusive flock(), so expunges can't happen while someone is still reading the file. Mails can however be marked with expunged-flag, and such mails should be treated as if they are already expunged. Expunged flag must not be removed. If the mail for some reason is wanted to be un-expunged, it must be copied as a new mail with new UID to the mailbox. Modifying flags doesn't require any locks. You'll simply write over those flags you wish to change. That's why each flag takes one byte. Safest way to expunge is to copy all non-expunged mails after the first expunged one to new file. Then update the index file with the new location for the UIDs, and at last ftruncate() at the position of first expunged mail in the original file. Alternative way to expunge is to just move the data over the expunged mails and fruncate() at the end. No index file updates necessary. This is more filesystem quota friendly, but if the expunging gets aborted in the middle it will corrupt the mails. Appending mails can be done by either locking existing file with a dotlock and appending to it, or creating a new file. If appending to existing file, also flock() it so expunging won't happen in the middle of append. If appending to new file, create it with .lock suffix and then check that the file without .lock wasn't already just created. When appending to existing file, check "Append offset" from file's header. If that offset is at the end of file, just append there. Otherwise read the mail's header from there. If it has a non-zero UID and index file says that the same UID exists in this file, jump over the mail and do the same checks for all the rest of the mails in the file. Once the check doesn't match or you reach EOF, update the append offset in the header to that offset and write your mail there. Initially write the UID in mail's header as zeroes ('0', not NUL). Once the append is completely finished, you'll have to update it with the new UID. You'll do this by locking index file, reading the latest last-used-uid and using the next value for your UID. Once you've written it, rewrite the index file with updated last-used-uid field and your UID added to it. After this, update the append offset in the mail file and unlock it. Keywords file ------------- Named "index.keywords". This contains mappings between keyword numbers and names. TODO: may be problematic with lockless flag writes.. Recent file ----------- "index.recent.<uid>" file tells what the last non-recent UID was. The file doesn't have any data inside it. When opening the mailbox you should find and rename() the existing index.recent.<uid> file to the new index.recent.<last-uid>. A successful rename() means the mails between <uid>+1 .. <last-uid> are recent for you. A failed rename() means that someone else managed to do it. You should look for the file again and if it was renamed to less than <last-uid>, you should try again. Nightly cleanups ---------------- Because expunged mails may be left lying around for a while, there probably should be some nightly check that cleans them up. Other cleanups that may be necessary after crashes are: - .lock files - expunged data at the end of files (can be checked with same rules as how appending determines the offset where to append) One problem with nightly expunging is how to expunge mails if the file is still locked by some process. Forced shutdowns may be annoying to users and can be difficult to implement.. Alternative locking strategy ---------------------------- The locking strategy as described above is optimized for high concurrency: Only if mail file is in the middle of being expunged, we're waiting on locks. With appending we may be waiting for existing appends to finish if we don't wish to create a new file for some reason. Other than those, reading and flag updating are completely lockless. The two downsides to this are: 1. flock() isn't available everywhere. It could however be replaced with fcntl() if that's available. NFS may not have either. 2. Expunges can't happen while multiple processes are accessing the mailbox at a same time. This may be a problem if the mailbox never has less than two processes accessing it. The alternative to flock()ing would be to simply handle unexpected end-of-file reads as a sign of expunge, which would require re-reading index file to see where the mails went (or if they were really expunged). This has two problems however. One is that flag writes couldn't catch expunges without locking, and another is that if you've already sent half a mail to IMAP client, you have no other choice than to disconnect the client if you can't send the rest of the mail. It might be worth it optionally. Especially for NFS people. Then you'd basically have the dotlock file that locks appends, expunges and flag updates. Reading would still be lockless. Also for the best performance the mail flags could be stored only in Dovecot's index files. In that case there's no need to update flags and the only downside with this locking strategy would be the potential disconnections, which probably aren't all that bad. Compatibility ------------- If needed, it would be possible to create new/ and tmp/ directories under the mailbox to allow mail deliveries to be in maildir format. The maildir files would be then either just moved or maybe be appended to existing mail files.

[Dovecot] Still weird UID ordering issues with maildir
by Todd Vierling 06 Dec '05

06 Dec '05

Nightly 20050829 (includes everything currently in nightly/ChangeLog): Sep 1 09:25:02 server dovecot: imap-login: Login: user=<tv>, method=PLAIN, rip=192.168.1.1, lip=192.168.1.3, TLS Sep 1 09:25:02 server dovecot: IMAP(tv): Maildir /home/tv/.maildir sync: UID < next_uid (1187 < 1188, file = 1125581033.7788_2.server.duh.org:2,) repeated every time I try to login. I had to nuke the dovecot indexes and let it reindex (which throws off the ordering of some messages). It had been working without incident since updating to 20050829, until now. -- -- Todd Vierling <tv(a)duh.org> <tv(a)pobox.com> <todd(a)vierling.name>

[Dovecot] 1.0-alpha2: assertion failed
by Wolfram Schlich 06 Dec '05

06 Dec '05

Hi, I am experiencing some problems with Dovecot 1.0-alpha2: --8<-- Sep 20 13:54:45 mailgateway dovecot: imap(support): file mail-index-view-sync.c: line 168 (mail_index_view_sync_begin): assertion failed: (!view->syncing) Sep 20 13:54:45 mailgateway dovecot: child 27047 (imap) killed with signal 6 --8<-- I tried to make it core as described in http://www.dovecot.org/bugreport.html, but without luck. The problem only happens to two accounts/users, which are used by more than one remote user/client at once. Dovecot OS is Linux 2.4.30 on RedHat 7.3. Clients are Thunderbird 1.0.6 on Linux and Windows. The mail storage format is Maildir. The indexes are stored in memory or in a separate directory (tried both). Any hints? -- Wolfram Schlich

[Dovecot] Segfault when using multiple servers
by Marc Maurer 06 Dec '05

06 Dec '05

Should it be possible to run multiple dovecot servers on the same mailboxes (Maildir in my case)? I've a setup where 2 dovecot 0.99.13 servers write to the same mailboxes, which dovecot apparently does not like too much. Example (using imap): - Login with mail client on server1 - Login with webmail on server2 - Delete a mail using webmail on server2 - Hit send/receive in the mail client Result: server1 segfaults. Is such a setup, which is basically a loadbalancing setup, allowed at all by dovecot? Cheers, Marc

[Dovecot] mbox separators ignored
by Kenneth Porter 06 Dec '05

06 Dec '05

Using dovecot-0.99.13-4.FC2 I grabbed a bunch of Mailman archive files from the Weather mailing list here: <http://www.buoy.com/pipermail/weather/> I gunzipped the older ones, then concatenated them all in correct order to create one big mbox file. I dropped it into my ~/mail folder and started my IMAP client (Mulberry) and opened the new Weather folder. It shows one gargantuan concatenated message, instead of lots of more reasonable-sized ones. The messages appear to be properly separated by "<linefeed><linefeed>From<space>". Why doesn't dovecot parse them into separate messages? I double-checked and removed any header lines with Content-Length, X-UID, X-IMAPbase, and X-Keywords. So this should look like a new mbox file with new content delivered by procmail. What's confusing dovecot?

We have used qpopper on our email server RH 9 for long. But recently as the number of people using the server has increased too fast we have to switch to dovecot. Things seem to be OK with the rate users post and receive emails. But from that time very often I see this when top: . dovecot-auth <defunct> And some people sometimes have to restart their outlook to receive emails Could any give us a hand to solve this problem.

[Dovecot] Virtual domain support using more than one MySQL database
by Dragiša Durić 04 Dec '05

04 Dec '05

For historical reasons I am stuck with situation where hosted domain users have their Mailbox info in mysql enabled vpopmail and our ISP's users have their info in nss_mysql. While I can easily move my users from vpopmail's mysql database to something more "native" to Dovecot, I see no problem to configure Dovecot, as I've already configured Postfix, to use this database directly and access mailboxes without problem. And I would not like to make separate auth database for ISP's users, as I don't like to have two watches when one suffice. Under courier-imap, I've configured my vpopmail domains to authenticate using it's vchkpw module, and mysql was left to me to be configured to use nss_mysql. It works well. Is it possible under Dovecot, and how? Is it possible to to MySQL auth using two different databases? It would be the best. TIA, dd

[Dovecot] Dovecot strange behaviors on Solaris
by Mario Nigrovic-rvvk40 03 Dec '05

03 Dec '05

Folks - I've been using Dovecot for some time now, but have only recently upgraded to 1.0alpha4. I'm struggling to get my configuration right and I'm seeing some truly bizarre issues. My Setup: Solaris 2.8 / Thunderbird / Procmail / Dovecot 1.0alpha4 My mail setup is only for me, so Dovecot runs at an odd port and under my userID. All my mail is in my home directory, which is on NFS (NetApp). The main mail receiver is a different machine which mounts my home directory. Typical entry from .procmailrc: :0 * ^(From|To|CC):.*@.*\<si2.org Maildir/.SI2/ Highlights from dovecot.conf: #default_mail_env = maildir:%h/.mail/Maildir:INDEX=/var/tmp/mario/dovecot default_mail_env = maildir:%h/.mail/Maildir:INDEX=MEMORY mmap_disable = yes #lock_method = flock lock_method = fcntl #lock_method = dotlock protocol imap { listen = *:2143 } auth_worker_max_count = 0 auth default { mechanisms = plain userdb passwd { } } When I run as above (INDEX=MEMORY), I have access to all my mail, but I'm seeing literally thousands of .nfs files created all throughout my .mail/Maildir directories, and Thunderbird periodically locks up. As the filesystem fills with useless .nfs files (I deleted 10000 from ONE mailbox directory this morning), everything gets really, really slow, and I suspect this contributes to Thunder bird's problem. But, if I run with the INDEX on a local disk, many mailboxes will not load (the most critical ones, of course...), but also some do. My inbox will list messages, but cannot display any. Others won't even list messages. I'm at a total loss how to proceed, here. I've tried everything I can think of to debug what's going on, but have gotten nowhere (well, I did discover the whole lock_method=fcntl trick). I've tried enabling rawlog, but am just not familiar enough with IMAP to get help from those logs. Here's what's happening in a typical mailbox: % pwd /home/mario/.mail/Maildir/.SI2 % ls -al total 544 drwx--S--- 5 rvvk40 lowv 425984 Dec 2 14:42 ./ drwx--S--- 64 rvvk40 lowv 16384 Dec 2 14:43 ../ -rw------- 1 rvvk40 lowv 15 Nov 16 07:16 .customflags -rw------- 1 rvvk40 lowv 24 Dec 2 14:38 .nfs00986 -rw------- 1 rvvk40 lowv 24 Dec 2 14:40 .nfs08986 -rw------- 1 rvvk40 lowv 312 Dec 2 14:11 .nfs16686 -rw------- 1 rvvk40 lowv 24 Dec 2 14:32 .nfs1A886 -- 40+ deleted here for brevity -- -rw------- 1 rvvk40 lowv 24 Dec 2 14:39 .nfsE3986 -rw------- 1 rvvk40 lowv 312 Dec 2 14:38 .nfsEF886 -rw------- 1 rvvk40 lowv 24 Dec 2 14:26 .nfsF3886 -rw------- 1 rvvk40 lowv 312 Dec 2 14:32 .nfsF9886 -rw------- 1 rvvk40 lowv 312 Dec 2 14:17 .nfsFF686 drwx--S--- 2 rvvk40 lowv 4096 Dec 2 07:58 cur/ drwx--S--- 2 rvvk40 lowv 4096 Dec 2 07:58 new/ drwx--S--- 2 rvvk40 lowv 4096 Dec 2 07:58 tmp/ % pwd /home/mario/.mail/Maildir/.SI2 Help!

[Dovecot] Silly newbie questions...
by Michael Segel 03 Dec '05

03 Dec '05

Hi, I'm relatively new to dovecot, less than 48 hours, and I've ran in to a few bugs in the installation/configuration process. Here's my set up. I have my own domain. Within the domain, I have a couple of Linux boxes. So I control both my primary and secondary mail servers. My Linux boxes are a mixture of SuSE 9.2, 9.3 and 10.0 (All based on age of the hardware.) I'd like to use Postfix for my MTA, which I have up and running, but I'd also like to add an IMAP server (hence dovecot) so I can get my mail from any of my PCs and my blackberry.) On my main mail server, I have KDE running and it uses ~/Mail/inbox/(cur,new,...) When I tried to use KDE on my other Linux server, I got it to authenticate and I could see the folders, but I couldn't see any of the mail. (Its all in cur subdirectory.) Now I did notice that when Postfix gets a mail message, its placed in /var/spool/mail/msegel which would imply its using an mbox format. So what am I missing? TIA! -Mike -- Michael Segel Principal MSCC

[Dovecot] corrupt attachments
by Brian Thompson 02 Dec '05

02 Dec '05

Not sure if this has already been covered, but any pointers or suggestions would be greatly appreciated. We just realized last night that dovecot-stable seems to be corrupting the attachments within users' inboxes. In an attempt to resolve the problem, we upgraded the mail server here to Dovecot 1.0alpha4 but it didn't help. To the best of our knowledge we didn't start experiencing this phenomena until we migrated from Solaris 8/Sparc to Solaris 10/x86 about 3 weeks ago. To be more specific: A non-corrupt attachment can be sitting within a user's mail spool (mbox format) and live there without a problem until an imap client goes to download the attachment via dovecot. At that time, dovecot seems to be stripping the last four characters from each base64 encoded ascii line within the attachment and rewriting the message within the mail spool without those characters. From then on, the attachment is permanently corrupt, even via local unix direct file access clients such as pine or elm. We've temporarily switched back to UW imapd, but users have noticed the decrease in speed - not having the indexing available. Again, any suggestions would be greatly appreciated. Thanks, Brian

[Dovecot] Multiple authentication databases and storage locations
by Odhiambo Washington 02 Dec '05

02 Dec '05

Hello Everyone, I am playing with the $subject matter using 1.0alpha4, and thanks to the archives, I lifted this one from Alexander Shikoff off and used it in my setup. auth default { mechanisms = plain user = root passdb pam { args = pop3 } passdb sql { args = /usr/local/dovecot/etc/dovecot-mysql.conf } userdb passwd { } userdb sql { args = /usr/local/dovecot/etc/dovecot-mysql.conf } } It seems to work, but I have virtual users as well as system users. System accounts have their mail stored as follows: default_mail_env = maildir:/home/%u/Maildir While virtual users have this: default_mail_env = maildir:/htdocs/virtual/spool/%d/%u/Maildir Now, virtual users can login because I have used their $default_mail_env in my configuration. I am stuck how to get system users to successfully access their e-mails. Here is the error I get: beastie# telnet 0 110 Trying 0.0.0.0... Connected to 0. Escape character is '^]'. +OK Welcome. Dovecot is Ready to serve. user wash +OK pass a_verysecret1 +OK Logged in. -ERR No INBOX for user. Connection closed by foreign host.

[Dovecot] After restart dovecot do not serves IMAPS anymore
by Marian Hercek 02 Dec '05

02 Dec '05

I had to restart computer yesterday and now Dovecot has strange behaviour. Dovecot is running and should serve IMAPS, but client Mozilla Thunderbird cannot connect. I tried openssl s_client -connect localhost:993 and it said only CONNECTED(00000003). A time ago when everything was OK, the listing after connection was "a bit" longer than it is now. I remember there was "OK, dovecot ready" or something like that. Now, there is none. Of course in /etc/dovecot.conf: protocols = imaps imaps_listen = * ssl_disable = no So, what's the problem?

[Dovecot] Dovecot logs to syslog (other than MAIL)?
by Steve Bigley 02 Dec '05

02 Dec '05

I see in the config file where I can enable syslog, but then all logging goes to the MAIL facility. I could find no reference to changing the facility:level for syslogging. Is that implemented, or planned? I know I could just write it to a file, but I'd prefer to use syslog because then I can pipe it to a central logging server.

[Dovecot] Unused SQL API
by Curtis Maloney 02 Dec '05

02 Dec '05

Greetings, recently I've been writing a database driver module for Dovecot to use SQLite. It's mostly for my own use, but I do recall other people have asked for this. Firstly - Timo, I grow to love your work more and more every day. :) I have not had any trouble figuring out what is needed of the driver, even without any API documentation. However, the one part of the driver that's given me pause has turned out to most likely be unnecessary. Whilst I was trying to work out how to deal with the sql_result->get_values() call without leaking memory, it seemed an odd method to have along side the other calls. So I decided to look for where it was used, to try to understand. Only, it isn't. The _only_ point I can find in the sources that calls that method is in the Postgress SQL driver. Am I missing something? -- Curtis Maloney cmaloney(a)cardgate.net

Is there a way to move an imap subfolder up one level? I have a bad mouse and every now and then I have accidentally dragged an imap folder on top of another folder. I am unable to get the original folder back up one level. I've tried using several clients and I can't get it to work with dovecot. I keep getting a "folder already exists" message. I'm guessing dovecot still sees the original folder before it was moved. Any tips... besides getting a new mouse? -- Andy

[Dovecot] Chrooting question
by Greg Pendler 01 Dec '05

01 Dec '05

Hi, All. I've got a feeling it's a simple matter and it was discussed on this list (i've searched the archive) but still all answers i've found didn't solve this problem. We want to move from UW-IMAP to dovecot, when users INBOX is /var/mail/USER_NAME and his folders are ~USER_NAME/mail/. In addition the host is an FTP server that uses chrooting in order to prevent users from accessing files outside their home directories. Our /etc/passwd line looks like this: some_user:x:1234:123:Some User:/home/./some_user:/bin/shell When i try to check mail on this host with this user i receive the following error message: Dec 1 08:21:11 server dovecot: [ID 935345 mail.error] Invalid chroot directory '/home' (user some_user) (see valid_chroot_dirs in config file) After which comes a line with: "Internal login failure" I've tried to configure different chroot options in configuration file, but had no luck at all. Of course when i remove the "." from passwd line everything works great (except FTP:). I'm using 1.0 alpha 4 on Solaris 9. Please let me know if you have such setup and what is the exact setting i need to add to configuration. Thanks in Advance, Greg

[Dovecot] dovecot 1.0.alpha4 hangs at auth
by Mihai Secasiu 01 Dec '05

01 Dec '05

I'm using dovecot 1.0.alpha4 on a freebsd 5.3 i386 system. Dovecot is configured to use mysql authentication and I'm running mysql 5.0.15 . Everything works fine, but after a period of inactivity (20-30 minutes ) when I connect and try to authenticate it just hangs. I noticed that the dovecot-auth worker process is not running anymore... from looking at the source code I understand that the dovecot-auth worker process is actually a client that connects to the main dovecot-auth process ( the server) I restarted dovecot and I straced the auth worker process ... after 20-30 minutes it just existed here is the output of strace : gettimeofday({0, 0}, NULL) = 0 poll([{fd=5, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=4, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}], 2, 0) = 0 gettimeofday({1133138508, 221796}, {0, 0}) = 0 gettimeofday({0, 0}, NULL) = 0 poll([{fd=5, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=4, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL, revents=POLLIN}], 2, 1999) = 1 gettimeofday({1133138509, 49095}, {0, 0}) = 0 read(4, "", 478) = 0 close(4) = 0 fcntl(7, F_SETFL, O_RDWR|O_NONBLOCK) = 0 read(7, "", 8192) = 0 fcntl(7, F_SETFL, O_RDWR) = 0 write(7, "\1\0\0\0\1", 5) = -1 EPIPE (Broken pipe) shutdown(7, 2 /* send and receive */) = 0 close(7) = 0 close(3) = 0 close(5) = 0 close(6) = 0 close(-1) = -1 EBADF (Bad file descriptor) exit(0) = ? Why is the auth worker exiting if it reads 0 from fd=4 ? is it possible to make it so that it does not exit ? and in the case it exits is there a mechanism to restart it? Another question would be why read(4, "", 478) returns 0 ? this means that the server closed connection right ? why would the auth server close the connection with the auth worker ? I had a similar problem with dovecot 0.99 but there I got a "login failed" error message immediately , with 1.0alpha4 it just hangs. I also used a nightly cvs snapshot and the problem is there too. Thank you for your time Mihai Secasiu http://denixsolutions.com/

Hello all, I am running Dovecot v1alpha4 on Fedora 4 from the command line (as opposed to deamon). Is there a recommended way to shut it down gracefully? Or do I just use killall -9 dovecot? I'm not using the included version, so I can't do SERVICE DOVECOT STOP. Thanks, Cliff

[Dovecot] Problem with openldap+nscd+dovecot
by Oliver Schulze L. 29 Nov '05

29 Nov '05

Hi, I'm having a problem with this setup: RHEL4 U4.2(Centos) + openldap + nscd The problem I see is that for some reason, after a couple of hours dovecot stuck in the auth procress. I do a : telnet localhost imap Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK dovecot ready. 1 login user pass (here is the delay) After passing a username/password, the process is like stuck for some reason. I have to killall dovecot processes and do a: service dovecot restart and it work again. I have 1.5GB left on the disk and this problem just appeared now after month of working correctly. Could it be the disk space? How can I debug the problem? Should I migrate de 1.0alpha4? Does alpha4 have a new code in the authentication phase? Regards, Oliver -- Oliver Schulze L. <oliver(a)samera.com.py>

[Dovecot] Not an IMAP4 Server?
by John Gray 28 Nov '05

28 Nov '05

I've been testing alpha4, and every once in a while my client (Thunderbird 1.5 RC1) tells me the dovecot isn't a valid IMAP4 server. This is usually (maybe always) when I first bring up the client up. If I just ask the client to get the mail again, it does so happily (without any errors). I must say I found dovecot as a pleasant surprise. We have been using UW. Which didn't scale well. I was considering going to cyrus, but dovecot seems to have given much (if not all) of performance improvements without all the hassle of conventing all the existing mbox mail to maildir.

[Dovecot] authentication failure messages in log
by Daniel 26 Nov '05

26 Nov '05

Hi I'm using Dovecot 1.0.stable branch on a production Fedora Core 3 server. All is running very well other than I getting tons of these messages in the log (/var/log/messages): Nov 26 13:38:56 bmw unix_chkpwd[19360]: password check failed for user (xxxx) Nov 26 13:38:56 bmw imap(pam_unix)[19359]: authentication failure; logname= uid=0 euid=0 tty= ruser= rhost=x.x.x.x user=xxxx However the sessions are authenticating correctly and the user is able to down load the mail fine. I have tested this. I send mail to an account then login and download the mail correctly, however my session gets the above in the messages log. Each log on to dovecot get ones of these messages in the log. It making the log file large. Any idea on what it is? Regards Daniel -- "Unix is simple.

[Dovecot] Problem with mysql authentication
by Jacek Osiecki 25 Nov '05

25 Nov '05

Hi, I'm trying to set up dovecot-stable (http://www.dovecot.org/nightly/stable/dovecot-stable-20051124.tar.gz) All seems to be prepared correctly, but... my dovecot can not access the mysql database :( Connection string goes like this (i tried changing the order of parameters, that's why password is the first in the line): connect = password=***** host=/var/lib/mysql/system/mysql.sock dbname=vmail user=vmail But - in dovecot log I see: dovecot: Nov 24 23:53:05 Error: auth(default): mysql: Connect failed to vmail: Access denied for user 'vmail'@'localhost' (using password: TAK) Same in mysql log: 051124 23:53:05 171 Connect Access denied for user 'vmail'@'localhost' (using password: TAK) All settings in connection string are 100% correct - I have pasted them from dovecot-sql.conf to command-line mysql client and it worked, I have logged in. My copy of dovecot has been compiled recently, so all libraries are correct. Mysql version is 5.0.15 - but I doubt it is the reason... Can anyone help? Thanks in advance!

[Dovecot] Newbie question: shared folders means..?
by Jeff Turner 22 Nov '05

22 Nov '05

Hi, The website says "Shared mailboxes aren't yet supported". Does that mean that one shouldn't have two mail clients (same username) accessing the same IMAP account simultaneously? Or that Dovecot doesn't support distinct users accessing the same 'shared' Maildir box? Cheers, Jeff

I'm trying to build a new 1.0+ copy of dovecot. I'm trying to build it so I can use SSL. I tried the ./configure --with_ssl= option, did a make clean, then a make and a make install.

[Dovecot] What's the best way to do this?
by Michael Segel 22 Nov '05

22 Nov '05

Hi, Got a situation where I have a couple of mailing list subscriptions as well as system generated e-mails from my clients' computers sending me warning messages. (Along with my normal load of personal e-mail). Does it make sense to set up virtual mailboxes (maildirs) one for each mailing list or group? Then using an IMAP client to subscribed only to the lists that I *want* to read? My biggest problem is that I have a blackberry and I don't want to get interrupted for non-critical e-mail. Or is there a better solution? TIA! -Mikey -- Michael Segel Principal MSCC 312 952- 8175 [M]

[Dovecot] How to add the footer to multipart emails
by Magnus Holmgren 21 Nov '05

21 Nov '05

I recently lerned that Mailman adds its footer to MIME multipart messages by putting the original message in the first part of a new multipart/mixed entity and the footer in the second part, with Content-Disposition: inline. It works well in Thunderbird at least, i.e. the footer is visible; the glitch is that the footer shows up as an attachment as well, as does my PGP/MIME signature. Would this be something for EoC to adopt? It would allow non-ASCII characters as well (but not in text/plain messages). -- Magnus Holmgren Linköping, Sweden

Re: [Dovecot] messages_count too large (2578 > 2566) Help!
by Rob Frohne 21 Nov '05

21 Nov '05

Hi Everyone, I found that I could "fix" the problem by moving all my messages from Maildir/cur/ to a temporary location and then try and load the inbox using Thunderbird which then saw no messages, and then moving them all back into Maildir/cur/ and then Thunderbird loaded them fine. I have had this funny business with messages_count to large happen twice tonight now. Both times after I deleted dovecot* in the Maildir/ folder. Hope this helps someone else if they end up with the same issue, or perhaps it might help Timo figure out what is happening. Thanks, Rob -- Rob Frohne, Ph.D., P.E. E.F.

[Dovecot] Big THANKYOU to Dovecot development team

Time for a positive message. As a (very) part time administrator of a small network running on an ecclectic bunch of machines I'd like to thank the dovecot team for developing such an easy to use and faultlessly functional product. Having been forced into finally replacing my UW IMAP server, I'm glad to have hit on Dovecot after struggling with mailbox transfer issues with cyrus and almost tearing my hair out. On my Fedora4 server, Dovecot was running withing a minute and reading all my folders in five further minutes, thanks Guys, Will.

[Dovecot] Shared Mailboxes, Per User SEEN flag and Mailing lists
by Reikan - Sidney Ferreira 20 Nov '05

20 Nov '05

Hi! Im making a small research about IMAP servers and it's features. As the subject suggests, I want make a shared mailbox, with per user \seen flag to work like a mailin-list works. The reason to use 1 shared folder is simple: Imagine 12k users sending 1KB messages each week, it will be 12+ MB of useless information. Many people told me that IMAP could do this, but now seem that it is a little harder then what they made it look like. Finally, some EXIM users told me that Dovecot could handle it a little better than Courier, so, Im here to try to find more information about it. Follows the mail that I received from an EXIM user.

[Dovecot] Sorting messages by date
by Stephen Allen 19 Nov '05

19 Nov '05

I've recovered a load of messages from a different mail server without it's index file (it was corrupted). I now have thousands of messages which display in Outlook Express (yes, you may puke at this), all as today's date. However when I read them in Pine, the date of each message is displayed correctly, but they're in no particular order whatsoever. There are several questions here, some of which aren't suitable for this list, but for completeness... 1. Does Dovecot store what it thinks is the date the message arrived, in it's index file? 2. Can I fake Dovecot into thinking the messages arrived on a different date by including something in the message headers, or changing the date/time stamp of each file (but I don't know how to do this)? 3. Pine correctly picks out a date from the message (although it doesn't sort by this order), and Outlook Express just displays everything as the date which it (or Dovecot) first saw the message. Does Outlook rely on Dovecot's sorting/date information or does it do it's own? Many thanks, Steve :)

This may seem off the wall, but can dovecot be configured to support a connection to a database server and use the database server to store the e-mail message and its attachments?

[Dovecot] Retention Policy Feature(?)
by Ted Strzalkowski 18 Nov '05

18 Nov '05

I am currently using dovecot 0.99.14p1 on OpenBSD 3.8, mbox format, procmail+sendmail MTA. I subscribe to quite a few mailing lists and currently have procmail sorting mail into the proper mboxes. I was hoping there would be some sort of retention policy feature built in to dovecot. I want to delete mail more than X days old from X folders. I have combed the documentation, list archives, and google. Is this a feature? If so, where can I find more information on it. If this isn't a feature, is it in the works or is it left out to keep things "slim line"? Ted Strzalkowski

[Dovecot] Authentication hanging with 1.0alpha4 - mysql issue?
by brock＠theskeptik.com 18 Nov '05

18 Nov '05

Hello, Recently, I configured my server (RHEL4, 2.6.9-22.0.1.ELsmp) to run postfix 2.1.5 and dovecot 1.0 alpha4. It connects to a MySQL database (mysql 4.1.12) to verify authentication. From 30 minutes to an hour after dovecot is started, authentication and mail access works perfectly. However, after those 30 minutes to an hour, further attempts to authenticate with dovecot result in "hangs" - no temporary authentication errors are reported to the client, and no errors are logged to the dovecot log. The dovecot is still running, and responds to connections, but once the password is sent, the server fails to respond. The following line is registered in the log with each authentication attempt after the "hang": > dovecot: Nov 17 22:44:41 Info: auth-worker(default): mysql: Connected to localhost (postfix) along with an eventual disconnection notice (although no Login: line is registered): > dovecot: Nov 17 22:45:41 Info: imap-login: Disconnected: Inactivity: method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Killing and restarting dovecot immediately fixes the problem, although it reappears after 30 minutes to an hour. Following is my dovecot-sql.conf: driver = mysql connect = host=localhost dbname=postfix user=dovecot_read password=**obfuscated** default_pass_scheme = PLAIN-MD5 password_query = SELECT password FROM mailbox WHERE username = '%u' user_query = SELECT 89 AS uid, 89 AS gid FROM mailbox WHERE username = '%u' (dovecot_read has SELECT access on the postfix database, and 89 is the uid/gid of the owner of the maildirs.) I searched through this list's archives over the last two months and couldn't find anything related to this. Does anyone have any idea what the problem could be? Regards and many thanks in advance.

[Dovecot] Mailbox isn't a valid mbox file
by Cliff Hayes 16 Nov '05

16 Nov '05

Hello all, I have a new installation of Fedora 4 and Dovecot 1.4.Alpha4 A small percentage of my users are getting unable to pop mail from a client (ie: Outlook), they get continually prompted for username/password. The error they get is: Mailbox isn't a valid mbox file. When I look in the file, I don't see anything unusual. There's not much info on the Internet about this problem. The only thing I found mentioned blank lines in the file. So, I tested and found that I'm able to get mail on other accounts regardless of whether there are blank lines in between messages. Thanks, Cliff

[Dovecot] Improper listening on IMAPS
by Marian Hercek 16 Nov '05

16 Nov '05

I want Dovecot handling IMAPS. /etc/dovecot.conf: protocols = imaps imaps_listen = * ssl_disable = no ssl_cert_file = /etc/ssl/certs/dovecot.pem ssl_key_file = /etc/ssl/private/dovecot.pem The problem is that Dovecot is not listening on 993 port, or there's something listening on 993, but it does not introduce itself. There's no problem if Dovecot listens on 143 (IMAP). When I telnet on 143, Dovecot introduces itself like this: $ telnet localhost 143 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK dovecot ready. But when I telnet on 993: $ telnet localhost 993 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. There is not other process that would be listening on IMAPS 993 port. Dovecot was compiled with SSL support: # ldd /usr/sbin/dovecot libssl.so.0.9.7 => /usr/lib/libssl.so.0.9.7 (0x20597000) libcrypto.so.0.9.7 => /usr/lib/libcrypto.so.0.9.7 (0x205c6000) libdl.so.2 => /lib/libdl.so.2 (0x206ba000) libc.so.6 => /lib/libc.so.6 (0x206be000) /lib/ld-linux.so.2 (0x20580000)

[Dovecot] Sub-Folder Query
by Kaan Kivilcim 16 Nov '05

16 Nov '05

Hi all, I have a question in regards to folders/sub-folders with dovecot and Microsoft Outlook 2000. When creating folders if you do not append a "/" to the end of the folder name you cannot create sub-folders. Is there any solution/work around so that users do not have to append a slash on the end of the folder name? I would like to use dovecot for about a 50-user IMAP server however adding a slash to the end of folder names won't go down well with the users who are not the most computer literate people.

[Dovecot] Need to move mail
by Brent Clark 15 Nov '05

15 Nov '05

Hi all My imap server is getting to the stange where I need to start worring about the disk usage. Due to the number of users we seem to be hiring, I need to start looking at a new mail server, suppose its a blessing in disguise too. Would it be ok to just tar my current users mail (there home directory, I dont use virtual setup) and the untar it on the new mail server. Is there anything that dovecot on the new machine will complain about. Obviously I would tar everything, indexes etc. Just something I was wondering. Kind Regards Brent Clark

[Dovecot] a proposal to increase the stability
by Udo Rader 15 Nov '05

15 Nov '05

Hi, we've been using dovecot for the past 2 years or so for our 3K+ mail accounts and have never regretted our step. Yet from time to time there appear to be, how shall I say, "major" problems in the daemon that of course are no reason to whine and complain about because dovecot is OSS and everybody can do something about it. And that's where I would like to make a suggestion. From our own software projects I am used to the usage of extensive testing frameworks, like junit for java based applications. I almost completely lack knowledge about C/C++ programming, so I have no idea if something like this could be done for dovecot. For "the other end" of the mail chain I know dumbster, which is a fake SMTP server used for testing MUAs. So maybe something similar could be done for IMAP/POP3 servers? What I am thinking of is to run those tests before anything new is released. On the other hand I cannot even estimate how much work would be needed for this ...

[Dovecot] Leftover mbox behavior from uw transition
by Adam Porter 15 Nov '05

15 Nov '05

Currently running dovecot 0.99.12 on a RHEL 3 server. This system used to use UW imap with mbox mailboxes, is now using dovecot with Maildir. (Actual user shell logins are not permitted.) Performance is tremendously improved. However, we still have users that have their client imap root set to the "mail" or "mail/" directory. (Can't reach/change them all easily.) As a result, people are still (inadvertently) creating/using mbox-style mailboxes (sent mail folders most often) on the dovecot server (dovecot of course handles them without complaining) which grow and hurt server performance. Now that we've figured this out, I think we could use mb2md in a script to convert these big mbox files to Maildir. (Is there a better way?) But what would be the smart way to prevent people from creating these mbox files and still have their client work correctly with their imap root set to "mail"? We currently use: default_mail_env = maildir:~/Maildir Thanks! -Adam

[Dovecot] entourage pop to dovecot imap migration
by wagner 15 Nov '05

15 Nov '05

I'm beginning to migrate my years of mail stuck in Entourage 2004 (MacOSX) to dovecot imap on Fedora FC4. No matter how I have tried I cannot get the status flags to migrate. Eg: all the mail, once transfered from the pop archive to the imap server looses all Status: and X-Status: flags and ends up being marked "new" on the imap side. After lots of testing it appears that, while simply having both pop and imap configured Entourage and dragging messages from the pop config to the imap area does move messages, all flags are lost. This also is the case if I export Entourage folders as mbox files and then import them into the imap server with Entourage or Mail.app. Has anyone else came upon this obstacle? Any advice? I am in the process now of gathering information to facilitate my own "migration utility". It seems the Entourage DB keeps the read/flagged/replied flags for each message in its own internals and doesn't deem it worthwhile to export them as part of it's mbox export nor retain them as Status or X-Status flags when moving messages from its pop DB to the imap server. I believe I can write a script to work on a set of found, for example, "replied to" messages to add an "X-Status: A" to their headers before moving them to the imap server. Same for "read" and "flagged" MS DB internals to Status/X-Status headers. With these headers added, moving them to the imap server, from my limited testing would seem to be the method to keep those status flags per message? Does dovecot use those flags or does it have its own means of storing that status information? Will it at least use those in the messages to populate its DB if it does have its own method? Flags I've identified so far: Status: O - old Status: RO - recent old(?) X-Status: A - replied to X-Status: F - flagged Thanks for any insight or suggestions.
