[Dovecot] Segfault when parsing configuration on x86_64
by Matthias Saou 25 Mar '06

25 Mar '06

Hi, Using the exact same build of 1.0.beta3, one i386 and the other x86_64, I get segfaults upon startup with the x86_64 version when using the exact same dovecot.conf file. Here is the error : # dovecot -F Unexpected eof found when reading file 'UNOPENED' (Errcode: 0) Segmentation fault (core dumped) And the backtrace (I don't have symbols for all libs, sorry) : (gdb) bt #0 i_stream_next_line (stream=0x52c3a8) at istream.c:182 #1 0x000000000040e345 in i_stream_read_next_line (stream=0x52c3a8) at istream.c:201 #2 0x000000000040aaa9 in settings_read (path=0x41798e "/etc/dovecot.conf", section=0x0, callback=0x409580 <parse_setting>, sect_callback=0x409a50 <parse_section>, context=0x7fbffff880) at settings.c:222 #3 0x000000000040a0e1 in master_settings_read ( path=0x41798e "/etc/dovecot.conf", nochecks=false) at master-settings.c:1159 #4 0x000000000040875a in main (argc=2, argv=0x7fbffffa18) at main.c:762 #5 0x0000003d4341c4bb in __libc_start_main () from /lib64/tls/libc.so.6 #6 0x000000000040357a in _start () #7 0x0000007fbffffa08 in ??

() The really weird part is that I've managed to get my dovecot.conf in a state where the problem no longer happens, but simply adding a line with '#', or removing trailing spaces (normally harmless) on some config lines makes the error re-appear. My quick guess would be that something is wrong with the config file parser on 64bit archs... Actually, I've just made some more tests, and it is "partially" reproducible on i386. In this part of my configuration : auth default { mechanisms = plain passdb sql { args = /etc/dovecot-mysql.conf } userdb sql { args = /etc/dovecot-mysql.conf } } There is a trailing space on both "args = ..." lines. Well, if I remove them, I get this message with the i386 build. When I put them back, all is fine again.

[Dovecot] Per-user "Seen" flags with shared namespace stored as maildir?
by Mark Lidstone 25 Mar '06

25 Mar '06

Hi all, I was wondering if the above was possible. I know that the "seen" flag is stored in the filename, but was wondering if anyone knew of a way to separate it out? I know this would strictly-speaking break maildir compatibility, but it would be extremely useful for shared folders. I've been given the task of replacing the (extremely heavily used) shared folders functionality of our Exchange server and have almost everything working. I have authentication working against AD, shared folders, per-user subscriptions, "mail enabled folder" functionality and seem to have sorted all the other permissions issues I've been having. Apart from a nice easy-to-use front end for changing folder permissions this is the last thing I can think of that I need to look into before I can show this to my boss.

[Dovecot] Authentication without password
by Feraudet Cyril 25 Mar '06

25 Mar '06

Hi all, for one of my developpements, I need to be able to connect an IMAP server with a login but without password. (I use dovecot 1.0.beta3) For the userdb, I use "userdb static" : userdb static { args = uid=114 gid=114 home=/mydev/mail/%u } But I don't know how to allow IMAP connection by my application without password. I won't connect to a database, having a user/password file or something like this ... I think to use "passdb checkpassword" to call a fake authentication script .... Anyone have a better idea ? Thanks, Cyril Feraudet

[Dovecot] How Can I Add New Flags
by Sezai KARATOZ 25 Mar '06

25 Mar '06

Hi all, I am new in Dovecot. I wanna use Dovecot in the big mail system about 4 million active or passive users. We use recently Courier Imap, but search mails process is so slowly. I tried Dovecot that it is better then Courier so much. But I have a problem with integration Dovecot to my system. I am using some extra flags in mails to mark them from others. For example I use a private flag "M" to understand it that this mail come from us as newsletter. I make some changes in code, but unfortunately I could'nt add this flag to Dovecot correctly. Please help me it that how can add this flag. I use maildir type Thanks, Sezai

[Dovecot] Shared namespaces
by Mark Lidstone 25 Mar '06

25 Mar '06

Hi all, I'm trying to replace the "Public Folders" functionality in Exchange server. At first I thought it'd be something easily do-able with an IMAP server so I immediately thought of Dovecot. I setup what I though would work and things started to go a little screwy with subscription settings and the like. I started off by making a public maildir folder (in /home/public/Maildir) and setting the namespaces up in /usr/local/etc/dovecot.conf like this: namespace private { separator = / prefix = INBOX/ location = maildir:%h/Maildir inbox = yes } namespace public { separator = / prefix = Public/ location = maildir:/home/public/Maildir inbox = no hidden = no } The folder /home/public/Maildir has owner root:users and mode 770, and the file dovecot-shared in there has the same owner and mode 660. I logged with Thunderbird as user 1 and everything seems to work fine. However, when I logged in as user 2 I was getting all kinds of errors. On checking the permissions of /home/public/Maildir/subscriptions it was user1:user1 with mode 600. So then I thought "well, I'll change it to user1:users 660 and then everyone should be able to change it". I was very wrong. Whenever someone changed it, the ownership changed to userx:userx 600. Even when I tried setting the ownership to root:users and mode to 640, anyone could change it and set it to their own name (thus preventing anyone else from using it). To be perfectly honest, I'd ideally like to give people separate subscription settings anyway. I thought about symlinking the folders in, but that makes it a manual process to add new folders to everyone's maildirs. Can anyone please give me any pointers?

[Dovecot] [PATCH] OpenSSL RNG initialization
by Vilmos Nebehaj 25 Mar '06

25 Mar '06

Hi, dovecot tries to use OpenSSL's PRNG to generate random numbers if there is no /dev/urandom found. Unfortunately, it is flawed in its present form, since the PRNG is not seeded before RAND_bytes() is called in src/lib/randgen.c (on systems which have /dev/urandom, OpenSSL automatically seeds its PRNG from the urandom device). Here's a patch to address this issue: it tries to seed the PRNG if there is no /dev/urandom present (which is likely the case if dovecot uses OpenSSL's RAND API). It can also be fetched from http://innoidea.com/~vili/dovecot_rng_init.diff -Vilmos Nebehaj Index: configure.in =================================================================== RCS file: /home/cvs/dovecot/configure.in,v retrieving revision 1.266 diff -u -r1.266 configure.in --- configure.in 28 Feb 2006 08:36:41 -0000 1.266 +++ configure.in 10 Mar 2006 17:15:01 -0000 @@ -358,7 +358,8 @@ AC_CHECK_FUNCS(fcntl flock lockf inet_aton sigaction getpagesize madvise \ strcasecmp stricmp vsnprintf vsyslog writev pread \ setrlimit setproctitle seteuid setreuid setegid setresgid \ - strtoull strtouq setpriority quotactl getmntent kqueue kevent) + strtoull strtouq setpriority quotactl getmntent kqueue kevent \ + getrusage) dnl * I/O loop function have_ioloop=no Index: src/lib/lib.h =================================================================== RCS file: /home/cvs/dovecot/src/lib/lib.h,v retrieving revision 1.20 diff -u -r1.20 lib.h --- src/lib/lib.h 25 Sep 2005 10:44:04 -0000 1.20 +++ src/lib/lib.h 10 Mar 2006 17:15:02 -0000 @@ -20,6 +20,13 @@ # include <stdint.h> /* C99 int types, we mostly need uintmax_t */ #endif +#ifdef HAVE_SYS_TIME_H +# include <sys/time.h> +#endif +#ifdef HAVE_SYS_TIME_H +# include <sys/resource.h> +#endif + #include "compat.h" #include "macros.h" #include "failures.h" Index: src/lib/randgen.c =================================================================== RCS file: /home/cvs/dovecot/src/lib/randgen.c,v retrieving revision 1.13 diff -u -r1.13 randgen.c --- src/lib/randgen.c 6 Jan 2005 19:08:19 -0000 1.13 +++ src/lib/randgen.c 10 Mar 2006 17:15:03 -0000 @@ -81,6 +81,42 @@ return buf; } +static void random_init_rng(void) +{ + int counter = 0; + struct timeval tv; +#ifdef HAVE_GETRUSAGE + struct rusage ru; +#endif + + /* + * If the RNG is already seeded, we can return + * immediately. + */ + if (RAND_status() == 1) + return; + + /* + * Else, try to seed it.

Is there anyway to get a message's filename through the imap server? I've been developing a program for awhile and just switched to dovecot from courier.

[Dovecot] first crack at auto-trash plugin
by David Powers 25 Mar '06

25 Mar '06

I have written an alpha version of an auto trash plugin for dovecot. When compiled in any mail expunged from a non-Trash folder is moved to a folder named Trash. As of yet the folder is not created if it doesn't exist (the process fails before expunge). I would appreciate feedback of any sort. In addition, I am currently getting an error I haven't been able to puzzle out in the logs when it runs: Mar 21 15:22:01 david dovecot: imap(david(a)grayskies.net): Timeout leak: 0x807fad0 I see that it seems to relate to transactions somehow, but my few hours of playing with dovecot haven't given me the answer - so ideas/patches to the code would also be nice. You can grab it here: http://wrath.grayskies.net/tarballs/auto-trash.tar.gz -David

[Dovecot] Method of archiving mail?
by Stephen Allen 24 Mar '06

24 Mar '06

Hello I have a situation in which a number of users have 10,000+ messages in the maildir, going back a few years. I'm not a fan of this many files lying around so I'd like to set up some kind of archiving, but one that will allow user's access to the old mails should they wish to see them. I thought of a cron job trying to sift through messages pulling those what were older than x days, then writing some script to process a request from a user (date/time/from/to/subject/body text) and copy matching messages to a "query" folder in the maildir. However, a) I'm not good at this kind of thing, and b) I have a feeling it's already been done before. Can anyone point me in the right direction please... is their software around to do this already? Many thanks, Steve :)

[Dovecot] Imap Timeouts
by Neil Wilson 24 Mar '06

24 Mar '06

Hi guys, I've got a client running 1.0.beta3 on SuSe 9.3 Everything has been running perfectly since it was installed about 6 months ago, but lately they've had issues with email clients not being able to connect to the IMAP server, until they close their clients(Thunderbird & Outlook) and then re-open them. They have roughly 70 users on their network, so it sounds like it could be too many active sessions at once, but I've tried changing a few things in the config, and so far nothing has resolved this. Any help would be appreciated. Regards.

[Dovecot] Can Dovecot 'slurp' into the INBOX from a mail spool file?
by Daniel Watts 23 Mar '06

23 Mar '06

Hi guys, I have a system whereby I am forced to deal with mbox files of /var/spool/mail/user1 (mbox text file) /var/spool/mail/user2 (mbox text file) etc Their mail homes are maildir format in: /home/user1/Maildir/{cur,new,tmp} /home/user2/Maildir/{cur,new,tmp} etc I can set things up so that the mbox inbox is shown using namespaces: namespace private { separator = / prefix = location = maildir:/home/virtual/%d/home/%n/Maildir/ } namespace private { separator = / prefix = mail/ inbox = yes hidden = no location = mbox:/home/virtual/%d/home/%n/mail/:INBOX=/home/virtual/%d/var/spool/mail/%n } This gives a rather odd folder structure as follows: INBOX Sent Drafts Trash mail/ --- INBOX myfolder1 myfolder2 Both of those INBOXes are actually the same folder. I'd ideally like to hide the mbox namespace entirely so that the user does not see any mbox folders. UW IMAP, with it's mbx format, allows you to just drop in a file called INBOX in mbx format and it will 'slurp' the /var/spool/mail/usersmbox file into the mbx INBOX. Has/could Dovecot have a similar feature whereby you specify a spool folder which is then 'slurped' into the local maildir INBOX? Not sure if I'm being clear enough here - do let me know if not! Much thanks, Daniel

[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

RE: [Dovecot] Shared namespaces - solved
by Mark Lidstone 23 Mar '06

23 Mar '06

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.

RE: [Dovecot] Shared namespaces - solved
by Mark Lidstone 23 Mar '06

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).

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?

[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

[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

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] 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
by Luca Corti 17 Mar '06

17 Mar '06

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

[Dovecot] virtual users

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}"? If there are docs I've missed, please RTFM with a link.

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] Imap crashes when trying to move messages

The imap process crashes when SquirrelMail wants to move a message to another folder. I have run imap in gdb and talked to it the same way SquirrelMail does and got a backtrace. I am using Dovecot beta3. I am using it in combination with XMail, which has maildir databases. My system is Gentoo Linux on x86. The same version of Dovecot works great for me on amd64 with exactly the same config.

[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

Hello, we have problems to access our users mailboxes with SquirrelMail. The log file /var/log/mail.log says permission denied, only one user is allowed to read his mail with SquirrelMail. We are running Debian Sarge, Mailserver is Postfix, imap server is dovecot. Our Mailboxes are stored in the mbox format. Folder of the mbox files is /var/mail/ the users are unix system accounts. Normally we read are mail with the POP-Client Outlook, this works well. But we also want to be able to read our mail (each user his own mails) via SquirrelMail /var/log/mail.log says: Mar 13 10:54:40 webserver dovecot: imap(unix-system-account): mkdir_parents(/var/mail/.imap/INBOX) failed: Permission denied In the folder where the mbox files are stored exists 3 folders called INBOX.drafts INBOX.sent INBOX.trash These folders are owned by the user who is able to read his mail via SquirrelMail and owned by the group mail. Only the user has read and write permissions. Does each user need to have his own INBOX Files? Could you please help me Kind regards, Roland

[Dovecot] Limiting Dovecot access by user-spesific ip addresses?
by Timo Neuvonen 13 Mar '06

13 Mar '06

Hi, Is there any possibility to limit access to mailboxes by user-spesific ip addresses? So, I'd like to have a configuration which by default restricts reading emails to company's own ip-address range. So far, this could be achieved by a basic firewall rule, but not any more the following: However, there is need for a few users to access their emails from world-wide internet, so there should be a possibility to define for certain users an option to skip the allowed address range check.

[Dovecot] Suggested patch: retain user's group privileges after logging into IMAP
by Lior Okman 11 Mar '06

11 Mar '06

Hi, I'm attaching a suggested patch that lets an authenticated user access shared IMAP folders even if the user doesn't directly own the storage, but is a part of a group that has permissions on the storage. This allows for the administrator to setup a shared mailbox with permissions given to a group instead of a user, and allow all of the users that belong to the group to access the mail according to the file-system permissions. What do you think? Is this the right way to do this, or am I missing something security-wise? I'm also attaching a bug fix for the LDAP passdb, where if the password scheme wasn't PLAIN, the password would be cleared from memory before being used to authenticate the user, and the authentication would fail. Regards, Lior

[Dovecot] Segfault problem when using TWO dovecot servers!
by Adam M. Dunn 10 Mar '06

10 Mar '06

Forgive me if this gets submitted twice. I had issues signing up for the listserv but I think I'm strait now. Hi all, I just started working with Dovecot and I'd like to use it for my organization, but I've run into a little problem. So far I love it and it does what I need. One thing we need is to be able to write to multiple mailbox formats on a per user basis (mbox or Maildir), and it does just that. I want users to be able to choose their format, and I can let it autodetect for me. The way I do that is I have Maildrop filters check for the presence of a ~Maildir, and if it finds that it writes to it, otherwise it writes to ~mbox. Dovecot is the only IMAP server I've found to read either or without hard coding one or the other in the config file. The problem: We also want failover. Mail/home directories are NFS mounted. I was planning to setup two dovecot servers, and noticed that whenever one server writes its temp files to the mail directory, if another server tries to read it you get a segfault and the child process fails and dies. So it basically looks like only one server can own the files, and it won't share. I considered trying to set the INDEX option on the mail boxes to write local indexes, but if I try to specify something like: default_mail_env = INDEX=/var/indexes/%d/%n, it doesn't work. Sure I can make it work by putting in a mailbox format before the INDEX, but then I can't use the autodetect which I need. Here's the syslog error: kernel: imap[13689]: segfault at 00007fffffe38000 rip 00002aaaaad3823f rsp 00007fffffe351f0 error 4 Any solutions? I really need this to work badly, or we may have to rethink our entire mail strategy. I'm also using the latest version 1.0beta3. I considered namespaces, but correct me if I'm wrong, you can't setup two namespaces and have it pick the first mailbox format available like the autodetect feature does. I tried seting up namespaces for both mbox and Maildir, but it just creates both. Please help someone. I need a solution to present to my boss, even if that means we have to run one server until the bug is fixed in the next version. Thanks, Adam

[Dovecot] POP3 extension to accept UIDL ranges?
by Matthias Andree 10 Mar '06

10 Mar '06

Greetings, is anybody aware of an extension to POP3 that supports UIDL ranges? It would be very useful for keep-messages-on-server setups (yes, I know, IMAP4 domain) to be able to do UIDL 21-42 to obtain just these 22 UIDs (this would always have to be a multi-line reply, just like UIDL without argument). If such a thing does not exist yet, perhaps a keyword such as "[X]UIDLRANGES" in the CAPA response might advertise this feature to clients. Regards, -- Matthias Andree

[Dovecot] Two namespaces with same prefix.
by Václav Haisman 09 Mar '06

09 Mar '06

Hi, I have yet another problem. First let me explain my setup. I used to use pine a lot so there are mbox mailboxes in ~/mail. Recently I added a Maildir too and moved most of the mbox mailboxes into Maildir format. Now I thoght it would be nice to have them all "in line" in Thunderbird so I tried this configuration: namespace private { separator = / prefix = location = %h/mbox inbox = yes } namespace private { separator = / prefix = location = maildir:%h/Maildir } The problem is that with this configuration I cannot access the ~/mail/box mailboxes. Thunderbird responds with "Mailbox doesn't exist: box" Is such kind of configuration with two namespaces having same prefix unsupported? Vaclav Haisman

[Dovecot] Default SELinux policy on Fedora FC4 prevents dovecot service from starting
by slohcine＠verizon.net 09 Mar '06

09 Mar '06

Hello, I recently setup a Fedora FC4 server to host e-mail and webapps. During the install, I turned on SELinux in active mode. All apps seems to work OK but Dovecot daemon won't start. In the audit log, I see this entry when I try to start the dovecot daemon. type=AVC msg=audit(1141464818.541:40305): avc: denied { read } for pid=1989 comm="dovecot" name=dovecot.pem dev=md2 ino=3646976 scontext=system_u:system_r:dovecot_t tcontext=system_u:object_r:cert_t tclass=file type=PATH msg=audit(1141499436.214:3266533): item=0 name="/etc/pki/dovecot/dovecot.pem" inode=3646976 dev=09:02 mode=0100600 ouid=0 ogid=0 rdev=00:00 I put SELinux into permissive mode and Dovecot works OK. Looks like dovecot does not assume the correct security context when it initializes and reads the cert file. My question for the list is what changes should I make to the SELinux policy to safely permit dovecot to read the file? I'm no expert at SELinux but hoping for some direction, or another way to solve this problem. Ideally, I'd like to keep SELinux in enforcing mode. Many thanks, Eric

[Dovecot] MySQL problem when using Dovecot as proxy
by Christian Jensen 09 Mar '06

09 Mar '06

Hi, I have just installed Dovecot as a POP3 proxy with great success. Its works flawlessly when i keep to the standard but since I am proxying a Microsoft Exchange 2003 (because the build-in POP3 in MS sux bigtime) I would very much like to use account names like: DOMAIN\username and this doesn't work when I include that in the MySQL table. In the logfile it clearly writes DOMAIN\username so its some kind of translation between dovecot and MYSQL. Any suggestions. I another solution would be to allow all users instead of having to create them in the MySQL table. Is this possible ? /Christian P.S Before Dovecot some Outlook users could only download max. 250kB through POP3 - now with Dovecot there is NO LIMIT! :)

My problem is that I can't get :INDEX and :CONTROL working at all: default_mail_env = maildir:~/:INDEX=/home/dovecot/index/%d/% n:CONTROL=/home/dovecot/control/%d/%n ls -l /home/dovecot/ total 8 drwxrwxrwx 3 dovecot dovecot 4096 Mar 8 07:52 control drwxrwxrwx 3 dovecot dovecot 4096 Mar 8 07:55 index (I've made everything 777 for testing) The error I get is: Mar 8 09:54:26 host imap(user(a)domain.com): mkdir (/home/dovecot/index/domain.com/user/.INBOX) failed: Permission denied If I su to the user(a)domain.com user I can manually create the directory OK. I'm using LDAP for authentication if that makes any difference. Any clues? Pointers? Need more information? -- Karl Latiss <karl.latiss(a)atvert.com.au> Atvert Systems

[Dovecot] Can I install in the following fashion?
by Stewart Dean 08 Mar '06

08 Mar '06

<permit me my perhaps foolish preference...an explanation> I run mail service for a small college. I've long joked that if someone stole the mail server, the phone would ring before the alarm (which has a 1 minute delay) did, that the user base expected 25x8x367 coverage. Making updates/upgrades to the mail server feels like a tightrope walk with no net. I always appreciated UofWIMAP because there is one binary. Doing and upgrade or backing it out is simplicity itself. I could compile the single binary on my compile machine, test the same binary on my testbed, and then drop it in my production machine and it would work with a minimum of surprises. So portable, so predictable, no security risk of a compiler on a production machine. Of course, /most/ of open source software has all these bits and pieces scattered everywhere. Oh, it may install initially just dandy, but come the day when It's Time For The Upgrade.... 1) can I do it quick and clean and 2) can I recover to what I had before quickly and correctly if the upgrade flops?????? Alas, Dovecot is sprinkled in many, many pieces...but at least, I think (right?) that they are all in the prefix-dir. Gulp. So. I am hoping I can do this: Build/Test Install 1) build/install in /usr/local/dovecot_bld/ Build### in the expectation that everything will be stuck down there. I don't want to put it into /usr/local/ because it will be in there with everything else....no way to get just the dovecot stuff.. 2) tar up the contents of my prefix directory and extract it over on my testbed under /usr/local/dovecot. Notice that the path to dovecot's "stuff" has changed from /usr/local/dovecot_bld/ Build### to /usr/local/dovecot I'm hoping that this won't be a problem. I will point the line in inetd at it and Everything Will Work. 3) Assuming I don't change anything and everything tests out (flawlessly!), I............. Introduction to Production (assuming that all the mailboxes, homedirs and the like have been sorted out) 1) make a tarball of the current working dovecot executables dir (/usr/local/dovecot) 2) extract the tarball there as before on the testbed machine and everything is fine. 2) if the update flops, I can bring back the tarball of the previous Dovecot incarnation My Questions: A) Will this work or are there dependencies I'm not aware of? B) Is there Some Better Way or..... I have this ongoing <ahem> discussion with the Open Source wonks that delight in many, many modules, libraries, etc. I /know/ the reasons a developer would want to do things that way, but, for those of use fielding the application, it's /so/ much easier and success/failure recovery is /so/ much more likely if....there are only one or two or three chunks that we can drop in or quickly back out. I realize that the developer is coding in large part for the utter joy of creating a wondrous, living, breathing edifice of code, that works, that works cleanly, that works as none has before. Yes. But I would think (IMHO) that the developer would receive a greater portion of the ego rush (also a big part of the developer stimulus) of overwhelming application acceptance (and thunderous applause), if he or she made it easy to support and upgrade! You see a sysadmin is so often an utter coward (I confess), who doesn't like unpleasant surprises, whose managment Really Doesn't Like Unpleasant Surprises. When I do my job really well, nobody knows I've done anything. OK...let me have it. -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] Busy studying
by Timo Sirainen 08 Mar '06

08 Mar '06

In case you're wondering why I haven't answered your mail. I try to do as much reading to exams as possible, and as little as possible anything else.. They're over in 2,5 weeks, so I'll start reading the old emails again then. :) BTW. If someone wants to help a bit, outlook-idle workaround seems to be broken. The timeout function never gets called in cmd-idle.c. I'm guessing it broke after I added the other timeout function for printing "OK Still here" message every 2 minutes, so the bug is probably in timeout handling in ioloop.c.

[Dovecot] Simple Question
by Charlie Davis 08 Mar '06

08 Mar '06

Brand spanking new to Dovecot. Trying to move over to it, got a few simple questions. 1) Is there any documentation on the .customflags file? Not sure what this is for... 2) I'd like to make a directory for every user NOT be writable. Meaning the email server (Exim) can put the mail down in the directory but a user can no move an email into it through Imap. I couldn't find a search for the mailing list either, so sorry if this has been asked 92380498 times. -Charlie

[Dovecot] Special treatment of ~/mail directory

Hi, would it be possible not to treat ~/mail specially and not to add mailboxes in the directory automatically? It would make migrating from IMAP-UW easier. Vaclav Haisman

[Dovecot] Undeleteable folders
by Casey Allen Shobe 08 Mar '06

We have 3 folders in every user's account which need to be there. Sometimes the users are stupid and delete or rename them. Is there any way to make them unmodifiable, but still allow them to see them, and move mail into/out of them?

[Dovecot] Dovecot with mbox and maildir
by Dario Ale 08 Mar '06

08 Mar '06

Hello, I have a question, i need migrate from old mail server to new mail server, the mailboxes format in the new mail server is maildir, in the old is mbox, the problem is that only the INBOXs are approximately 64Gb (are 7000 users), in the new I installed Dovecot, in the old is UW-Imap. The question is, Is there any form for have mbox and maildir simultaneously with Dovecot? I am using Postfix, my MDA is procmail, this write mailbox in the correct format, then i can copy all INBOXs and HOMEs to the new mail server, and change the mailbox format "slowly", supposedly procmail detecting the mailbox format and Dovecot could detect too. Thanks, very much. pd: sorry, my english not is good. -- Dario Ale (dario.a en telpin.com.ar) Area Internet Telpin - Jason 1026 - Pinamar (7167) www.telpin.com.ar

[Dovecot] self-signed certificates
by Benjamin 08 Mar '06

08 Mar '06

Hallo, i'm having troubles installing self-signed certificates for dovecot. After installing, dovecot generates a key and cert. But he is using the wrong common name (where does dovecot get this name from?). I tried deleting them and installing a handcrafted cert with this: openssl genrsa -out mail.key 2048 openssl req -new -key mail.key -out mail.csr openssl x509 -req -days 4312 -in mail.csr -out mail.cert -signkey mail.key after that i tried to update the dovecont.conf to point to the new files. But dovecot refuses to read them, i allways get an error, that dovecot can't read the certificate file. With dpkg-reconfigure dovecot-common, dovecot generates new ones, and they are working fine, but have the wrong common name. Thanks in advance Regards Benjamin

Will that be a problem? I'm not sure, but I think this setting is used for compile time - it's where dovecot expects to find include files, it doesn't mean that anything will be installed there. If you're really concerned, then use "make -n install", and go over the commands that make would have run, you will be able to see exactly where everything goes. Or you could run "make install" inside a chroot jail. I also seem to recall that I saw a script somewhere that could trace the "make install" procedure and print exactly where it puts everything. It was being used for converting .tar.gz "make-based-installations" to rpms. > Q2: Will dovecot not be able to find system resources it needs? Dovecot should be able to find everything it needs, assuming the configuration files are ok. > Tar'ing up a directory is doable. RPM'ing hundreds of files scattered > here and there, perhaps referenced by others, perhaps with new > additions/deletions you don't know about sounds like an heroic task. Tar`ing a directory is doable, but doesn't lend itself well to reusing components and sane system management. When you use RPM/DPKG for manging your configuration, each package you install is responsible for its own files and nothing more. The packaging system makes sure that nothing conflicts or overwrites existing files. If you accidently untar a file with bad configuration files in it, they will probably overwrite your existing configuration. RPM/DPKG will save your old configuration files. Tar can't help you verify that what you installed is what is actually running. RPM -verify can make sure that no trojan has been installed instead of a file provided in an RPM file. And the list goes on and on. > Does anybody see how simple it is to upgrade UWImap with its one binary? Just as long as there is only one binary. AFAIK, UWImap doesn't support configuration files, on the assumption that the sysadmin probably doesn't know enough to create a valid configuration. The downshot of that is that there is a limit to what you can do with UWImap's one binary :-) Lior > > Lior Okman wrote: > > Looking at the debianized version, the bulk of the files are placed in > > € > > or under /usr/lib/dovecot, with all of the configuration files in > > € > > /etc/dovecot, and relevant binaries under /usr/bin and /usr/sbin. > > € > > > > € > > However, reading from the comment in the begining of the default > > € > > dovecot.conf file, you can probably compile your own version of > > € > > dovecot where you specify the following parameters to configure: > > € > > "--prefix=/usr --sysconfdir=/etc --localstatedir=/var > > € > > --with-ssldir=/etc/ssl". > > € > > Just make sure to replace all the paths with where you want to install > > € > > this version of dovecot. > > € > > > > € > > Lior > > € > > > > € > > On 3/7/06, Stewart Dean <sdean(a)bard.edu> wrote: > > € > > > >> Hmmm, hadn't thought of RPM.

[Dovecot] dspam plugin mailing list?
by Johannes Berg 07 Mar '06

07 Mar '06

Hi, Every once a while I get mail about my dspam plugin. While that's great (tells me people are using it or at least like the idea), sometimes I think the discussions then should be accessible to others. I'm thinking of setting up a new mailing list for it so answers get archived, are searchable, and I don't necessarily have to reply to everything. I'm not sure if that's feasible though, there probably aren't *that* many users, and sometimes the questions are more dovecot questions. Would anyone on this list (esp. Timo of course) mind if I were to note on the plugin page that discussion and questions should be sent to this (the dovecot) mailing list? I'll still be reading here and answering questions, of course, but then if something crops up that's more dovecot than plugin related it's at the right place already, or if I'm off for a few days and someone else knows the answer... If there are any objections I'll just set up a private mailing list instead and ask anyone interested to join (it'd be very low volume I guess) :) johannes

[Dovecot] mbox sync: UID inserted in the middle of mailbox...
by Simon Bowden 07 Mar '06

07 Mar '06

Hi, We're getting a lot of errors like this: Mar 7 10:02:35 imapserver dovecot: imap(user1): mbox sync: UID inserted in the middle of mailbox /home/user1/mail/mail/INBOX.Trash (8 > 2, seq=2,idx_msgs=6) We have several hundred people using the server, and at least 22 have had this error in the past 24 hours. The numbers at the end change between each user, which I guess you'd expect. I was able to make the errors go away for one user by removing the index files (rm -rf ~/mail/.imap/INBOX), so I'm guessing they were corrupt. However, the problem with this is that: 1) It requires user intervention 2) The symptom is that they aren't seeing any new mail in the affected mailbox. I had thought that the indexing stuff would not *give up*, but would reindex a directory if there was a problem. Anyone able to help? Some info on our setup: /home/user is nfs-mounted. We allow them to configure their mbox/maildir type and location, but obviously this is only relating to mbox ones. Here's the config file, stripped of comments and blank lines: ==================== protocols = imap imaps ssl_cert_file = /etc/ssl/certs/imapd.cert ssl_key_file = /etc/ssl/private/imapd.pem ssl_ca_file = /etc/ssl/certs/cacert.pem log_timestamp = "%Y-%m-%d %H:%M:%S " login_processes_count = 6 first_valid_uid = 40 mail_extra_groups = default_mail_env = mbox:~/mail/:INBOX=~/.incoming-mail mmap_disable = yes mail_drop_priv_before_exec = yes protocol imap { mail_executable = /usr/local/mail/imap-wrapper imap_client_workarounds = outlook-idle delay-newmail tb-extra-mailbox-sep } protocol pop3 { } auth default { mechanisms = plain gssapi passdb pam { args = session=yes * } userdb passwd { } user = root } plugin { } ==================== /usr/local/mail/imap-wrapper is just a script that lets them configure the setup a bit (effectively change value of MAIL, and some namespace stuff), ultimately running /usr/lib/dovecot/imap. The nfs mount options on the home directory mount are: rw,hard,intr,rsize=8192,wsize=8192,nosuid,nodev,vers=3,proto=udp Thanks! Cheers, - Simon

[Dovecot] Dovecot as a smart IMAP proxy
by Timo Sirainen 07 Mar '06

07 Mar '06

Do you see a use for an IMAP proxy where the proxy would be able to execute hooks which modify mail contents, such as transparent encrypting/decrypting mails, or maybe some virus-filtering? It would need at least some kind of IMAP command/reply parsing capabilities, so it might be able to do all kinds of other things. Maybe one potential use case would be Cyrus Murder-like proxying to multiple IMAP servers to distribute the mailboxes. But that might be done better as an imap process plugin, or maybe as IMAP mail storage backend. Anyway, the reason I'm asking this is because I was asked to add mail encryption/decryption capabilities to Dovecot's IMAP proxy, but I'm not sure what would be the best way to handle this. In any case it would be a plugin or a new binary which is executed instead of imap binary, but can I do it in a way that would actually be useful for Dovecot project in general?

[Dovecot] [IMAP] Strange! No problem when I import mails from local to server.
by Xueron Nee 07 Mar '06

07 Mar '06

Hi, All: I hava just post a question that says when I move mail from one folder to another, mails were holded in the tmp directory of the target folder. I try to move mails from server to local and then, move them from the local folder to the server side folder, it works fine :) I refresh the tmp directory and could see tmp files created-unlinked, and all mail imported to the target folder currectly. What's the problem when I move mails between server-side folders? -- Xueron Nee <xueron(a)gmail.com>

[Dovecot] [IMAP] mails holded in tmp directory
by Xueron Nee 07 Mar '06

07 Mar '06

Version: 1.0.beta3 OS: Redhat AS 4 I use the cvs version of Dovecot to run my IMAP server. When I move some mails from one folder to another, only 1 or 2 mails are moved, while others were holded in the tmp directory of the target folder. So, what's the matter? I use becky and Outlook as client, and both of the two have the same problem. Thanks :) -- Xueron Nee <xueron(a)gmail.com>
