[Dovecot] Losing messages
by Stian Jordet 23 Mar '06

23 Mar '06

Hi, I have been running dovecot cvs happily for.. well.. very, very long now. Don't remember when I switched from 0.99, but it was back in the test-days, long before the alpha's. Anyway, it seems to have been working very well all the time. But recently three of my clients have claimed to have lost mail when moving from Thunderbird. I even experienced it myself once. I'm using Evolution 99% of the time, and have never seen any problems with that - but that doesn't mean the problem only occurs with Thunderbird. When moving mail from one folder to another, everything seems fine, except that the mail isn't in any folder anymore. It _seems_ related to this: Mar 14 14:46:53 buick dovecot: imap(larsmj): Fixed index file /home/larsmj/Maildir/.Junk/dovecot.index: first_recent_uid_lowwater 40 -> 36 Mar 14 14:46:53 buick dovecot: imap(larsmj): Corrupted index file /home/larsmj/Maildir/.Junk/dovecot.index: Duplicate header extension keywords But I'm not sure. Either way I get these lines rather often for some users. What does it mean? Anyone seen anything like it? I really don't like the idea of losing clients mail... I hope someone can shed some light on this. Best regards, Stian

Hi Steffen, I'm using procmail as my LDA and postfix as my MTA. Also, in my case I need all email to any email address at my domain starting with "pr" then some numbers to go into these folders. The reason for this is I'm trying to setup an open-source replacement for our mail-enabled Exchange Public Folders at the moment (can you believe you can't search sub-folders in Exchange Public Folders?!). First I created a fake user with it's own group: adduser public_folders Next, I added all the relevant users to that group: usermod -G public_folders john_smith usermod -G public_folders jon_doe Next, in /home/public_user/.procmailrc I put the following: MAILDIR=/home/public_folders/Maildir # If any mail gets through to this account without having a project number address, # put it in an "Unfiled" folder. DEFAULT=$MAILDIR/.Unfiled/new * # This line just gets me the project number (also makes sure the preceding letters * # are uppercase - otherwise we could end up with separate folders for pr123, Pr123, * # pR123 and PR123. * PROJECT_NUM=`formail -xTo: | egrep -o [pP][rR][0-9]+ | tr '[a-z]' '[A-Z]'` # This is not absolutely necessary, but I prefer to keep logs so I can see where # emails have been stored if anything goes missing. LOGFILE=$MAILDIR/procmail.log # This UMASK setting is basically what you're looking for, Steffen. The mail files # on the disk are stored with mode 660. UMASK=007 # Because these are public folders receiving a lot of mail, I've put in a big message # ID cache. :0 Wh: msgid.log |formail -D 2097152 $MAILDIR/msgid.cache * # Notice that regexps in .procmailrc are case insensitive unless you specify otherwise * :0 H * * ^To: .*PR[0-9]+(a)mydomain\.tld * { * PROJECT_FOLDER=$MAILDIR/.Projects.${PROJECT_NUM} * * # Here I basically check if the folder exists. If not it's created with mode * # 770 - this is also important. * :0 Wic: * * ? test ! -d ${PROJECT_FOLDER} * # Make all the subfolders, or they will be made by dovecot when the first user * # tries to look in there messing up the permissions on that folder. * |mkdir -m 770 -p ${PROJECT_FOLDER}/new;\ * mkdir -m 770 ${PROJECT_FOLDER}/cur;\ * mkdir -m 770 ${PROJECT_FOLDER}/tmp * * # And here I finally store the email * :0: * ${PROJECT_FOLDER} * } Make sure the file has mode 0600 public_folders:public_folders or procmail will ignore it. Next, I had to set the following permission on the public_folders home folder: chmod 770 /home/public_folders Next, I put the following namespace into /usr/local/etc/dovecot.conf: namespace public { separator = / prefix = Public/ location = maildir:/home/public_folders/Maildir:INDEX=%h/Maildir/public_folders/indexes:CONTROL=%h/Maildir/public_folders/control inbox = no hidden = no } Next, I made sure the relevant folder structure existed with the right permissions (I cheated and did this as root): cd /home/public_folders mkdir -p Maildir/new cd Maildir mkdir cur mkdir tmp mkdir -p .Unfiled/new mkdir .Unfiled/cur mkdir .Unfiled/tmp for file in `find`; do chown public_folders:public_folders $file if [ -d $file ]; then chmod 770 $file else chmod 660 $file fi done *Next, I made a file called /etc/postfix/virtual.pcre with the following content: * * /^[pP][rR][0-9]+(a)mydomain\.tld/ public_folders@localhost * *And finally I put the following into /etc/postfix/main.cf: * * virtual_alias_maps = pcre:/etc/postfix/virtual.pcre, hash:/etc/postfix/virtual Then I restarted postfix and away I went. Now when someone sends an email to "pr123(a)mydomain.tld" it gets put into the relevant project folder under the "public _folders" maildir. If you don't need the automated project filing, ignore the lines with a * at the start. I hope someone finds this helpful.

Heh heh heh. Whoops. I've spent a few hours digging around in the source and nearly posted a kludge of a patch I'd written to give a kind of half-baked attempt at getting group-usable subscriptions files. Then I came across something in the source........ In the config file, do something like the following: namespace public { separator = / prefix = Public/ location = maildir:/home/public/Maildir:CONTROL=%h/Maildir/Public inbox = no hidden = no } Notice the "CONTROL=" part of the location line. This tells dovecot where to store "control" files (of which the "subscriptions" file is one). As you can see I have told it to put the control files in each user's home space. This means not only are there going to be no permission problems, but each user can have separate subscriptions (because everyone is using their own "subscriptions" file). Of course I could also have set the CONTROL dir to be something like "/home/public/Maildir/control/%u" so they would all be stored in one place, but I prefer the idea of having it in the user's home folder. After searching the wiki I don't see the CONTROL option explained anywhere. Is there any chance someone could add that in somehow (a link from the SharedFolders page would be extremely useful also). Channing - you were very nearly right there.

[Dovecot] Save sent mail on server
by Benjamin 23 Mar '06

23 Mar '06

Hi dovecot list users, currently we have some email accounts which get maintained by different people. If any of this users sends a mail, it is only saved on his local machine, but not on the imap server. But i'll need them to get saved on the mail server for backup purposes and that every user can see which mails have been sent through this account. Is this possible? Thanks in advance Regards Benjamin

[Dovecot] mail shown throught outlook, shows todays date
by bclark 23 Mar '06

23 Mar '06

Hi all I seem to be sitting with an interesting situation where by I need to copy mail from Exchange to dovecot (Maildir) I used a mixture of solution (Moz Thunderbird, fetchmail and outlook) to copy and test the mail. The interesting thing is, once I have some mail on the dovecot, the date displayed on Mozilla is correct, but the mail shown throught outlook, shows todays date (thats for all mail). I logged in squirrel mail, that too correctly displays the date. Almost seems as Outlook (office 2000) looks at the date / time stamp of the file it self as opposed to opening and reading the mail and reading the necassry tags. If anyone could help me understand this (is this a dovecot issue), I would really appreciate it. Kind Regards Brent Clark

[Dovecot] Tiny kqueue specific patch
by Václav Haisman 22 Mar '06

22 Mar '06

Hi, I have noticed from logs that (only handful of occurrences during whole week) sometimes there is some kind of unrecognized event on handle and the branch with i_panic() in ioloop-kqueue.c:io_loop_handler_run() catches it. This patch allows the i_panic() to print some more info about the nature of the unrecognized event so that I can find out what it is about. Since it is really rare event I ask anybody who sees Dovecot dying with "Unrecognized event" in logs to try this patch and report back with the output if it triggers again. The patch is against version 1.beta3.

[Dovecot] One dovecot, multiple domains
by Ben 22 Mar '06

22 Mar '06

Hey guys, I've got dovecot configured to work perfectly for virtual users across different domains. It's great. My problem is that, as far as I can tell, dovecot makes me use one SSL certificate across all my domains. That's not what I want. Is there a way I can get dovecot to use the cert for mail.foo.com when somebody is logging into a foo.com account, and the cert for mail.bar.com when somebody is logging into a bar.com account? Am I missing something obvious, or asking the impoosible?

[Dovecot] Using mbox INBOX with Maildirs?
by Mark Winslow 22 Mar '06

22 Mar '06

Thanks for everybody's tips on the mbox to maildirs converter. I was unaware that Maildirs was a common format not specific to dovecot, so I was searching using a dovecot keyword. I'm having this problem now with inboxes. I want to use maildirs, but my mail is delivered to an mbox. I can't seem to get dovecot to recognize the inbox location. Is something like: maildir:%h/Maildir:INBOX=/var/mail/%u impossible to use? What I'm trying to do is slowly merge people from mboxes to maildirs, so I have to use the passwd file per user maildirs settings with some sort of recognizeable inbox. I'm using sendmail as my mail server. Do I have to tell that to put the mail in the right inbox format? Thanks. __________________________________ Discover Yahoo!

[Dovecot] compilation and installation of dspam-plugin
by Stefan Schmidt 21 Mar '06

21 Mar '06

hello johannes, i just discovered your wonderful plugin for dovecot. it was pretty much exactly what i was looking for, only that i didn't know that yet :) "Instead of moving mail into special folders, the user has two actions available: moving it out of the SPAM folder and moving it into the SPAM folder. The dovecot plugin watches these actions [...] and tells dspam that it made an error and needs to re-classify the message, depending on the action the user took. The user can now move the message directly into whatever folder she choses, and it all works. [...]" i think this is the most usable and intuitive approach to dspam-training i have seen so far and would love to integrate dspam with this plugin into my current setup (postfix + maildrop + dovecot). i have installed dovecot via package from the debian stable section [1] therefore i am currently using version 0.99.14 in my setup. despite this difference in version i gave your betacode [2] a try together with the source of the corresponding dovecot-version [3], hoping it wouldn't crash and burn when used with my earlier version of dovecot. but i didn't get to the point where i could actually testdrive it. i tried compiling the plugin with the instructions contained in the file, but the compilation didn't suceed. ---------------------------------------------------------------------- stefan@myserver:~/sources/dovecot-dspam-plugin/dovecot-1.0.beta3/plugin$ gcc -fPIC -shared -Wall -I../src/ -I../src/lib -I.. -I../src/lib-storage -I../src/lib-mail -I../src/lib-imap -I../src/imap/ -DHAVE_CONFIG_H spam_plugin.c -o spam_plugin.so In file included from ../src/imap/common.h:4, from spam_plugin.c:32: ../src/lib/lib.h:6:22: config.h: No such file or directory In file included from ../src/lib/lib.h:23, from ../src/imap/common.h:4, from spam_plugin.c:32: ../src/lib/compat.h:31:4: #error uoff_t size not set In file included from /usr/include/sys/socket.h:35, from ../src/lib/compat.h:80, from ../src/lib/lib.h:23, from ../src/imap/common.h:4, from spam_plugin.c:32: /usr/include/bits/socket.h:36: error: conflicting types for `socklen_t' ../src/lib/compat.h:51: error: previous declaration of `socklen_t' In file included from /usr/include/netinet/in.h:23, from ../src/lib/compat.h:81, from ../src/lib/lib.h:23, from ../src/imap/common.h:4, from spam_plugin.c:32: /usr/include/stdint.h:111: error: conflicting types for `uint_fast32_t' ../src/lib/compat.h:46: error: previous declaration of `uint_fast32_t' /usr/include/stdint.h:141: error: conflicting types for `uintmax_t' ../src/lib/compat.h:38: error: previous declaration of `uintmax_t' In file included from ../src/lib/lib.h:23, from ../src/imap/common.h:4, from spam_plugin.c:32: ../src/lib/compat.h:107: error: redefinition of `struct iovec' In file included from ../src/imap/commands.h:6, from ../src/imap/client.h:4, from ../src/imap/common.h:5, from spam_plugin.c:32: ../src/lib-storage/mail-storage.h:435: error: syntax error before "mail_get_virtual_size" ../src/lib-storage/mail-storage.h:435: warning: type defaults to `int' in declaration of `mail_get_virtual_size' ../src/lib-storage/mail-storage.h:435: warning: data definition has no type or storage class ../src/lib-storage/mail-storage.h:438: error: syntax error before "mail_get_physical_size" ../src/lib-storage/mail-storage.h:438: warning: type defaults to `int' in declaration of `mail_get_physical_size' ../src/lib-storage/mail-storage.h:438: warning: data definition has no type or storage class In file included from ../src/imap/commands.h:7, from ../src/imap/client.h:4, from ../src/imap/common.h:5, from spam_plugin.c:32: ../src/lib-imap/imap-parser.h:45: error: syntax error before "uoff_t" ../src/lib-imap/imap-parser.h:45: warning: no semicolon at end of struct or union ../src/lib-imap/imap-parser.h:45: warning: no semicolon at end of struct or union ../src/lib-imap/imap-parser.h:47: error: syntax error before '}' token ../src/lib-imap/imap-parser.h:47: warning: type defaults to `int' in declaration of `_data' ../src/lib-imap/imap-parser.h:47: warning: data definition has no type or storage class ../src/lib-imap/imap-parser.h:48: error: syntax error before '}' token ../src/lib-imap/imap-parser.h:72: error: field `args' has incomplete type ../src/lib-imap/imap-parser.h:125: error: syntax error before "_imap_arg_literal_size_error" ../src/lib-imap/imap-parser.h:125: warning: type defaults to `int' in declaration of `_imap_arg_literal_size_error' ../src/lib-imap/imap-parser.h:125: warning: data definition has no type or storage class ---------------------------------------------------------------------- just in case it matters: i currently have gcc 3.3.5 installed. greetings, stefan [1] http://packages.debian.org/stable/mail/dovecot-common [2] http://snipurl.com/nvol [3] http://www.dovecot.org/releases/dovecot-1.0.beta3.tar.gz

Hello, I've attached a patch that adds an additional expando to pop3_uidl_format. The additional expando (%M) expands to the md5sum of the filename (which is already available via %f.) This UIDL style is compatible with tpop3d when using Maildir. The patch is against dovecot 1.0 beta3, and I'd love to see it be merged into the official tree.

I can imagine having a 'pipe' action instead of 'run' that would give the command the message on stdin for example. johannes

[Dovecot] VERY cool add-on request.
by Adam M. Dunn 20 Mar '06

20 Mar '06

I would like to have the ability to execute a command on a folder based on a user doing something like copying a message to that folder. This could be accomplished with a config file directive. For example, this would be EXTREMEMLY useful as a spam learning hook. Take a scenario where each user has their own spamassassin bayes database, and you want to give the users the ability to train their own database based on what they think is SPAM. It would be nice to give all the users a folder called Spam, and tell them to just copy/move mail into that folder, and spamassassin will automatically learn about it. If we had a configuration hook where you could execute on a copy/move, then I could tell Dovecot whenever a user puts a message into the Spam folder, execute 'sa-learn --spam --file %s' on that message. Sure we could just do an external script in a cron job to do it every hour or something, which I'll probably do in the mean time, but often users will just delete messsages after they copy into it. Doing it through IMAP means spamassassin will learn about it immediately. How cool would that be? It seems like an easy hook to implement. I would like to patch it myself for my own use, but I'm not very proficient in C. I saw someone on the net patched Courier to do the same thing so I know I'm not alone in wanting this. Anyone know how I could patch it? Can we add that to the feature request list? ~Adam

[Dovecot] mbox to maildir conversion

Usage is something like: > > src/plugin/convert-tool user /home/user mbox:/home/user/mail:INBOX=/var/mail/%u maildir:/home/user/Maildir I would RTFM but searching wiki.dovecot.org turns up nothing. Give me more hints and I will add a new wiki page. The feedback the command gives is $ ./convert-tool Fatal: Usage: <username> <home dir> <source mail env> <dest mail env> Why does the tool want a home directory? What does it look for there? I know you say the syntax is the same for other tools but I don't know it for them yet either. :-) Guessing at the syntax for the source, it looks like the first thing is the format of the source (mbox:) followed by a directory containing mbox format files. The INBOX portion specifies the location of the mbox that the MDA puts incoming messages into. I can see the variables defined in doc/variables.txt, got that already. Is it intended to run both directions? That is, if I swap the last two args is will it convert maildirs into mboxes? This comment from Stian seemed pertinent as well. > But there is at least one "bug" with this; you should convert .'s in > mbox names to underscore or something, else it looks weird. Other than > that, it seems to work fine :) ..but I am unsure what 'looks weird' means. Can you give an example? Why is this tool under 'plugins' when it appears to be a separate utility? My guess is that it was easier to put there due to the build environment. Maybe it should install to a bin or sbin location? Thanks for all you do, Brian

[Dovecot] auto move of purged mail to trash
by David Powers 17 Mar '06

17 Mar '06

I am moving a courier installation over to Dovecot and I am wondering if there is a way to set Dovecot to automatically move purged items to trash (under IMAP). Additionally, is there a way to automatically delete old items from a Trash folder? -David

Re: [Dovecot] Converting huge mbox to Dovecot mbox + indexes
by Bertrand Leboeuf 17 Mar '06

My mistake, good point. I thought that creating the indexes would take a long time, but after a couple of tests, I found that Dovecot is so fast that it beats UW IMAP even while creating the indexes and after that, it is just fast.

[Dovecot] mbox to maildir: what about INBOX
by Bertrand Leboeuf 17 Mar '06

17 Mar '06

I migrated from UW IMAP/Qpopper to Dovecot using: # indexes on /var/indexes is faster: local, not NFS mouted default_mail_env = mbox:~/mail:INBOX=/var/mail/%u:INDEX=/var/indexes/%u # Qpopper pop3_reuse_xuidl = yes The new mail is sent to in /var/mail/%u in mbox format How can I migrate some users to maildir and have them receive their emails either in POP3 or IMAP. (lots of big files to convert) How does new email get spooled in the right INBOX (POP3/IMAP) ? Thanks. Bertrand Leboeuf leboeuf(a)emt.inrs.ca

[Dovecot] LDA Sieve debugging

Hello all, I've installed and setup the LDA with postfix. I'm trying out Sieve support, and wrote the following global script: require "fileinto"; if address :contains "To" "luca(a)mydomain.tld" { fileinto "Spam"; } and tried to send an email to that address. The sieve script seems to be processed and sieve-global.scriptc is compiled, but the message is not filed in the correct folder. Is there a way to debug the script execution? thanks -- Luca Corti PGP Key ID 1F38C091 BOFH excuse of the moment: Internet exceeded Luser level, please wait until a luser logs off before attempting to log back on.

[Dovecot] PAM authentification problem
by Vladislav Kyjasko 17 Mar '06

17 Mar '06

Hi everybody, we try to migrate our IMAP service from uw-imap to dovecot because of horrible server slowdown when a lot of people poking in theirs huge imap folders. So, I try to run testing instance of dovecot on different imap port (12143) I have trouble with authentication by PAM module of MIT Kerberos. It successfuly works for authentificate users of wu-imap but not for dovecot. I see in dovecot.log messages like that : Info: Dovecot v1.0.beta3 starting up Info: auth(default): client in: AUTH 1 PLAIN service=IMAP lip=10.0.0.154 rip=10.0.0.148 Info: auth(default): client out: CONT 1 Info: auth(default): client in: CONT 1 AGtDNLamUjvADNLamUjQRsbw== Error: auth(default): pam(kyyashko,10.0.0.148): Child process died Info: auth(default): shadow(kyyashko,10.0.0.148): invalid password field Error: auth(default): PAM: Child 6748 died with signal 11 Info: auth(default): client out: FAIL 1 user=kyyashko temp Almost all users are in kerberos DB and has in local shadow field "*KRB*" instead of encrypted password. So, line "shadow ... invalid password field" is OK (when I made a local password in shadow the login was success) My dovecot.conf looks like: sl_disable = yes protocol imap { listen = *:12143 } auth_default_realm = FZU.CZ auth_verbose = yes auth_debug = yes auth_debug_passwords = yes auth default { mechanisms = plain passdb pam { } userdb passwd { } user = root } original /etc/pam.d/dovecot I introdused by lines auth sufficient pam_krb5.so auth required pam_unix2.so use_first_pass nullok or tryed to substitute whole file pam.d/dovecot by actualy working one of imap: #%PAM-1.0 auth sufficient pam_krb5.so auth required pam_unix2.so use_first_pass nullok auth required pam_unix2.so account required pam_unix2.so but similary fruitless. Which direction I have to dig? P.S. Dovecot was built from dovecot-1.0.beta3-6.src.rpm on SuSE 9.0 with the same result like from dovecot-1.0.beta3.tar.bz2 :(

[Dovecot] Install/configure on FC4 with maildir and mysql
by Netlink Tech 17 Mar '06

17 Mar '06

Hello, I have a FC4 x64 server that I am configuring/testing. It had dovecot 0.99 loaded after I did a yum update. That worked great with mbox, the passwd file, and test users in /home/users/username. I would like to be able to authenticate virtual users by 'username(a)domain.com' and have them be able to use squirrelmail or Outlook/Outlook Express to access their email. Users have no reason to have a login (shell) account on this machine. I also would like to use the maildir format for performance. I also have hundreds of users currently on a RH9 mail server using qpopper in mbox format, hashed mail spool. Questions: 1)Is a mysql database the best way to support "user(a)domain.com" email users? (they don't have any reason for a shell account on this machine) 2)What version of dovecot should I be using? I prefer RPMs and at http://www.dovecot.org/list/dovecot/2006-February/011467.html I found http://fedora.ivazquez.net/yum/4/x86_64/RPMS.alternatives/dovecot-1.0-0.iva… I installed this and then configured procmail for maildir delivery. I configured dovecot-sql.conf for mysql driver...but the mysql driver does not appear to be compiled in this rpm. 3)Anyone have any general tips on how to configure such a beast? Thanks, Curt

Hello All. I've been reading the virtual user howto but cant get the login working. dovecot.conf is below [0] if anyone can offer some pointers. I'm confused about the format of /etc/imap.passwd [1] also. Does the "pass" word in the example need to be plaintext, or the MD5 string from do. Also, what is the significance of "{plain}"?

It's my server and it's still running and working properly. Dovecot version is (as on the newer server) beta3, but the first Dovecot running was beta2 I think. Imap works properly on that server. Anyway Dovecot shouldn't crash ever if the index files are broken!

[Dovecot] Shared Folders Problem. Bug?
by Adam M. Dunn 16 Mar '06

16 Mar '06

I'm trying to get shared folders to work, and I've noticed a few issues. I created a private and public namespace, the private one with autodetection for Maildir or Mbox, and the public one for a public folder. Something like this: namespace private { separator = / inbox = yes prefix = location = } namespace public { separator = / prefix = Public/ location = maildir:/var/mail/public } My plan is to eventually setup a public area for users to drop Spam and Ham into for my spam bayesan filter. The problem is the Wiki says if you drop a file in the public area called 'dovecot-shared' with the same permissions and ownership, that any new files dovecot creates there will use those same attributes. This does not seem to be the case. I created a Maildir folder identical to the one on the Wiki, named everything 'dovecot:dovecot' since my dovecot server will be running as that user, as well as the 'dovecot-shared' file. I get permission denied errors in syslog when I try to access it via an IMAP client. The only way I can make it work is ignore the dovecot-share file and put all users in a common unix group and make the Public folder group 'rwx'. Also, I would like to be able to make the Public folder writable, but not readable. It seems if I take the read bit away, my IMAP clients complain. Does anyone know how to make that work? One thing about the namespaces while I'm at it. I had to put my private namespace first followed by the public one. If I reversed them, all the subfolders except the inbox in my mail directories disappear from the client. Is that a bug too? Thanks, Adam

[Dovecot] Problems with Oulook Clients
by Patrick Carney 16 Mar '06

16 Mar '06

Hello all. I have problems with clients running Outlook 2003 that keep getting IMAP server timeout errors, "mailbox in an inconsistant state" Are there any mods to be made to the config file that could eliminate this? It happens about ever 10minutes. Here is what our previous Sys Admin sent me on our setup. dovecot is the IMAP server that allows clients to connect and get to their mailboxes. Postfix is that part of the mail system that moves messages around, from one server to another and puts them in the appropriate mailboxes. Thanks Patrick

[Dovecot] Strange dovecot-uidlist behavior on maildir conversion
by allen petersen 15 Mar '06

15 Mar '06

Hi. So I just moved my email over from mbox to maildir. For the most part the conversion went fine, but I had a bit of an odd thing happen when I accessed my mail through dovecot. It seems that when I ran mb2md to convert my mailboxes from mbox to maildir, I got a lot of messages created that look like 1142356176.000000.mbox:2,RS 1142356176.000421.mbox:2,S 1142356176.000001.mbox:2,S 1142356176.000422.mbox:2,RS 1142356176.000002.mbox:2,RS 1142356176.000423.mbox:2,S 1142356176.000003.mbox:2,RS 1142356176.000424.mbox:2,S and so forth. Now, that really should be fine, that I can tell; each message has the same timestamp and a different, sequential delivery identifier. However, for some reason when dovecot accessed this directory, it created UIDs for these messages like so: (from dovecot-uidlist) 1 1142362834 915 1 1142356176.000488.mbox 2 1142356176.000207.mbox 3 1142356176.000425.mbox 4 1142356176.000117.mbox 5 1142356176.000398.mbox 6 1142356176.000335.mbox I have no idea where this order came from, but it's clearly not the order that I would have expected. I would expect that dovecot would sort these messages by timestamp, followed by delivery identifier. Instead, it put them in a seemingly random order. And, of course, my email client by default shows messages in the order that it gets them from the server, so now when I look at my email all of my old messages are shuffled until I do an explicit sort by date. Any idea why this is happening? Is there some reasoning behind this, or is it just a bug? I looked through the archives a bit, but didn't find a mention of anyone else with this particular problem. I suppose I could just create the initial uid lists by hand and put them in the correct order, but that really doesn't seem like the correct solution. Or I could actually dig through the source and find out exactly what it's doing, but, well, I figure that asking the list first is easier. For reference, I'm running dovecot 0.99.14-1 on debian sarge. I though that I was doing a good job by reproducing this on the newer version my ubuntu desktop, but it turns out that it's running the same version. :) -allen

[Dovecot] Rootless configuration
by James Davis 14 Mar '06

14 Mar '06

I'm trying to setup a rootless configuration so I can better manage the e-mail that comes to the mailbox of a unix account I have. I've successfully compiled Dovecot and followed the instructions for a rootless configuration, tweaking my config until Dovecot returns no errors. However I've got to a stage where upon running ~/..../sbin/dovecot it just quits with no server running and no errors. Any ideas? My rather small and basic configuration file is as follows... # Base directory where to store runtime data. base_dir = /home/jamesd/imap/dovecot/run/ # Protocols we want to be serving: protocols = imap listen = * ssl_disable = yes log_path = /home/jamesd/imap/dovecot/logs/ info_log_path = /home/jamesd/imap/dovecot/logs/ ## Login processes login_dir = /home/jamesd/imap/dovecot/run/login login_chroot = no login_user = jamesd ## IMAP specific settings protocol imap { listen = *:10143 } ## Authentication processes auth default { mechanisms = plain passdb passwd-file { args = /home/jamesd/imap/dovecot/etc/passwd } user = jamesd } Many thanks, James -- http://www.freecharity.org.uk/ - Free hosting for charities http://jamesd.ukgeeks.co.uk/

[Dovecot] Shared maildir through namespace help...
by Brice Figureau 14 Mar '06

14 Mar '06

Hi, I'm a happy user of dovecot since the 0.99.x days, and recently switched my user base to 1.0b2. Now, to the point, I got a request (from marketing) to share a lot of maildirs between two (and possibly more) accounts. Those two accounts have differents uid/gid. The maildirs are actually in one of the account. I thought I could possibly craft a public namespace for those maildirs as explained in the wiki, but alas, it doesn't quite work as I expected: excerpt of dovecot.conf: namespace public { separator = / prefix = marketing/ location = maildir:/home/marketing/Maildir:INDEX=%h/ } users belong to the marketing group. $ find /home/marketing/Maildir -ls 4767751 4 drwxrwxr-x 3 marketing marketing 4096 Mar 14 11:57 . 4767752 4 drwxrwsr-x 6 marketing marketing 4096 Mar 14 11:59 ./Maildir 4767753 4 drwxrwsr-x 2 marketing marketing 4096 Mar 14 11:57 ./Maildir/cur 4767754 4 drwxrwsr-x 2 marketing marketing 4096 Mar 14 11:57 ./Maildir/tmp 4767755 4 drwxrwsr-x 2 marketing marketing 4096 Mar 14 11:57 ./Maildir/new 4767756 0 -rw-r--r-- 1 marketing marketing 0 Mar 14 11:57 ./Maildir/dovecot-shared >From there, the namespace is visible from all the IMAP accounts. Now, if a user creates a new folder in this public namespace, here is what I get: 4767757 4 drwx--S--- 5 brice marketing 4096 Mar 14 12:05 ./Maildir/.test 4767758 4 drwx--S--- 2 brice marketing 4096 Mar 14 11:59 ./Maildir/.test/cur 4767759 4 drwx--S--- 2 brice marketing 4096 Mar 14 11:59 ./Maildir/.test/new 4767760 4 drwx--S--- 2 brice marketing 4096 Mar 14 11:59 ./Maildir/.test/tmp 4767761 0 -rw-r--r-- 1 brice marketing 0 Mar 14 11:59 ./Maildir/.test/dovecot-shared 4767762 4 -rw------- 1 brice marketing 6 Mar 14 11:59 ./Maildir/subscriptions As you can see: the cur,new,tmp dir don't have the right permissions (they're not rw for the group), and moreover, the 'subscriptions' file has the same problem. The result is that any other user don't have access to this directory even if it is in a public namespace. Now, the question, is: is that setup could work only with virtual users setup with a static uid/gid ? Is there a mean to implement what I want ? Does using symlinks instead of the namespace could work ? Regards, -- Brice Figureau <brice+dovecot(a)daysofwonder.com>

[Dovecot] mbox to maildir conversion - good idea regarding Outlook?
by Gerhard Hofmann 14 Mar '06

14 Mar '06

Hi list, first of all, many thanks to the Dovecot authors for supplying an IMAP server that works well with M$-Outlook! I have used UW-imapd for quite a while and was annoyed by frequent "imap...timeout..." error messages. Now I'd like to give maildir format a try because I want to use email sub-folders. What are other Outlook users' experiences with maildir? Is it as stable as mbox? Regards Gerhard

[Dovecot] tls
by lenny＠edpausa.com 13 Mar '06

13 Mar '06

is it possible to turn off TLS and only SSL ? The reason are many reasons for this, one major being the fact that TLS is automatically discovered by many clients on the standard ports, thus requiring a valid cert for production use, while SSL could be set up on some unknown to anybody port with self signed cert for testing, etc... thank you
