[Dovecot] Basic configuration problem "not a directory"
by Einar Flesaker 26 Apr '05

26 Apr '05

Hi, I've been struggling with getting dovecot up and running the last hour, but I seem to be stuck. When logging in (which I can do successfully) my connection is dropped, and the following is outputted to my dovecot log: dovecot: Apr 26 09:56:52 Fatal: chdir(/bin/false) failed with uid 513: Not a directory dovecot: Apr 26 09:56:52 Error: child 27345 (imap) returned error 89 .. But I'm certain the relevant directories exist. Relevant configuration details are as follows: * [dovecot.conf] valid_chroot_dirs = /var/spool/vmail default_mail_env = maildir:/var/spool/vmail/$d/%n/ * [passwd sample] einar@domain.com::513:513:/var/spool/vmail/domain.com/:/bin/false:: * [directory listing] [root@server einar]# pwd /var/spool/vmail/domain.com/einar [root@server einar]# ls -l totalt 12 drwx------ 2 virtmail virtmail 4096 apr 26 07:27 cur drwx------ 2 virtmail virtmail 4096 apr 26 08:48 new drwx------ 2 virtmail virtmail 4096 apr 26 08:48 tmp I'd be very grateful for any assistance, any ideas of what might be wrong. Is there any easy way to see the relevant directory that /bin/false exits on? -Einar-

Just a note, I backported some larger mbox changes from 1.0-test67. Hopefully works, but if you're going to try it test it well first :) Should fix some issues related to X-IMAP/X-IMAPbase header handling and maybe some other mbox related problems as well.

[Dovecot] configuration problem: maildir folders and messages not found
by Bram Mertens 26 Apr '05

26 Apr '05

Hi Perhaps I've been going too far OT in my previous thread or perhaps I just didn't explain my problem clear enough so forgive me for trying again. I have configured fetchmail to fetch my mail from my ISP's POP3-server. I have set up procmail to filter messages and deliver all non-filtered messages to the folder ".IN-catchall/" in "$HOME/Maildir" After sending some test messages the "Maildir" folder in my home-folder looks like: m8ram@medion:~$ tree -a Maildir Maildir |-- .IN-catchall | |-- cur | |-- new | | `-- 1114356268.8424_0.medion | `-- tmp |-- .IN-testing | |-- cur | |-- new | | |-- 1114354955.6900_0.medion | | `-- 1114356175.8292_0.medion | `-- tmp |-- .INBOX | |-- .IN-testing | | |-- cur | | |-- new | | | |-- 1114354955.6900_0.medion | | | `-- 1114356175.8292_0.medion | | `-- tmp | |-- .imap.index | |-- .imap.index.data | |-- .imap.index.log | `-- .imap.index.tree |-- .customflags |-- IN-catchall |-- cur |-- new `-- tmp 16 directories, 11 files Because I have been using the mbox format to test dovecot so far I had to modify my dovecot configuration but no matter what I try none of the messages above appear in evolution or thunderbird. Can anybody tell me what I need to add/remove/change in my config? I'm running: m8ram@medion:~$ /usr/sbin/dovecot --version 0.99.14 on debian testing /etc/dovecot/dovecot.conf contains the following: protocols = imap login = imap login = pop3 mail_extra_groups = mail default_mail_env = maildir:/%h/Maildir auth = default auth_mechanisms = plain auth_userdb = passwd auth_passdb = pam auth_user = root When using mbox I used: default_mail_env = mbox:~/mail/:INBOX=/var/mail/%u I also tried the following for maildir: default_mail_env = maildir:~/Maildir default_mail_env = maildir:/home/%u/Maildir But neither worked.

[Dovecot] ldap uid with static gid problem
by Farkas Levente 26 Apr '05

26 Apr '05

hi, i'd like to use dovecot to authenticate from ldap. in ldap each user has it's uniq uid and gid. unfortunately with postfix we can't use uniq uid/gid since in this case we have ot create all user's home in advance. so we decided to use uniq uid and a common gid in postfix since in this case postfix can create new users maildir and deliver new mails. so i'd like to use everyone's own uid in dovecot, but a common gid (same as in postfix). but how can i do so? i read the wiki, but the problem is if i use: auth_userdb = ldap /etc/dovecot-ldap.conf then i have to define ldap attrib name in dovecot-ldap.conf: user_attrs = mail,,,uid,uidNumber,gidNumber what should i use in the last field in user_attrs? or it's not possible with dovecot to define this? i'd be very said in this case:-( any advice? thanks in advance. yours. -- Levente "Si vis pacem para bellum!"

[Dovecot] libexecdir and localstatedir problem
by Marten Lehmann 26 Apr '05

26 Apr '05

Hello, I'd really like to define the finale libexecdir and localstatedir through the configure-script. But the Makefiles are rewriting them. Not $libexecdir is used, but $pkglibexecdir. And $pkglibexecdir is always defined as $libexecdir/dovecot. But I don't want this trailing "/dovecot". Same with localstatedir. I want dovecot to use a certain path. But to this path, a "run/dovecot" is appended. I surely could build some patchfiles to change the Makefiles. But it would be easier, if you could add a new directive --pgklibexecdir to the configure-script. I don't know where the "run/dovecot" is defined, but it would also be very fine to set it in the configure-script (specially when upgrading to new releases) instead of defining them all in the dovecot.conf (base_dir, login_dir). Regards Marten

[Dovecot] 1.0-test68 released
by Timo Sirainen 26 Apr '05

26 Apr '05

http://dovecot.org/test/ Recommended update, has had a lot of testing today. No new big features. Changes: - LDAP authentication should work finally? - Some header lookup fixes that should fix sort/threading issues - Don't crash with 0-byte size mboxes - Transaction log fixes. Also rotate .log file to .log.2 file, allowing more history and less "transaction log file lost" messages. - SEARCHing multiple headers might have crashed - mbox: When first message was expunged we might have gotten "uid-last unexpectedly lost" errors. - recent flag counter wasn't updated in index file header always even if the recent flags were removed - UIDVALIDITY changes are handled more transparently - Added --rundir configure option (not actually tested, does it work? :) - etc.

[Dovecot] INBOX can't be deleted
by Marten Lehmann 26 Apr '05

26 Apr '05

Hi, surely it can't and it shouldn't. I'm just wondering why a check for "INBOX" is done in src/imap/cmd-delete.c AND src/lib-storage/index/maildir/maildir-storage.c. The first is clear because it gives an imap-error to the client. But for which case is the check in maildir-sorage.c? Just to be absolutely sure? The reason for me to ask is, because I need to disable deletions for five folders: Drafts, Infected, Junk, Sent and Trash. A certain webmail-interface and spamfilter will rely on these folders, so nobody shall be able to delete or rename them. First I placed the checks in cmd-delete.c. Should I place them in maildir-storage.c additionally? In normal circumstance, the check in maildir-storage.c should never be reached, right? Regards Marten

[Dovecot] Dovecot Stable (or: When is 1.0 coming to a server near you?)
by Rich West 26 Apr '05

26 Apr '05

I'm mainly just curious, but what version of dovecot is considered to be stable enough to be running in a production environment? We're running the 0.99.13 version shipped with FC3 and, while experiencing great performance gains over UW-IMAP, we have hit a couple of snags here and there (random and infrequent characters at the beginning of a mailbox, periodic duplication of a message here and there, etc). I figure we should upgrade to something a bit more current, but I am not sure what the "recommended" verion would be.. Also, perhaps more important, what's the roadmap to getting 1.0 finalized? What's the timeframe? :-) -Rich

However, I'm still experiencing a segmentation fault with today's snapshot of -stable, as shown in the following gdb backtrace. [I'm still running FreeBSD 5.3] Can you see where it comes from ?

[Dovecot] Quota
by Timo Sirainen 25 Apr '05

25 Apr '05

If anyone's interested about implementing quota code for Dovecot (there were a few of you before! :), now it's finally your chance to do it quite easily. With the API changes committed today to CVS, it's now much easier to write plugins that modify mail-storage behavior. So, I finally fixed my half-working quota plugin that had been lying there for a while. It implements the RFC2087 quota commands for IMAP, a generic quota API that should allow pretty much any kind of quota implementation, and the actual quota limit checking for saving and copying mails. As an example there's an implementation which just scans through all files in a directory and sums their sizes. Currently it can be made to work only when starting from command line, eg.: export QUOTA=~/mail:storage=1024 export MODULE_DIR=/usr/local/lib/dovecot/imap ./imap The QUOTA variable is passed to the quota implementation. In this case quota-dirsize reads it, figures out that ~/mail is the directory where to count the files, and 1024kB is the maximum for quota. I think I'll change the master process code so that any unrecognized varibles that come from userdb are fed to imap/pop3 processes. That way you could simply make the userdb return the quota value (and set other user-specific settings as well). Available from: http://dovecot.org/patches/1.0/quota.tar.gz Unpack under dovecot/src, compile command is at the beginning of quota-plugin.c I'm still wondering where this code should be placed. Maybe the core implementation should be built into Dovecot, while the different quota implementations would be plugins? ..And even better would be if Dovecot's build process was modified so that it's possible to specify with configure script what to compile in and what to compile as plugins.. Anyway, comments welcome, Maildir++ implementation welcome, other implementations welcome as well :)

[Dovecot] File isn't in mbox format - Couldn't open INBOX
by Rich West 24 Apr '05

24 Apr '05

While I saw another thread on the list similar to the issue I was experiencing (http://dovecot.org/pipermail/dovecot/2005-February/006168.html) I was wondering if there was a way around this problem (the thread simply suggested upgrading, but are the later version (specifically the 1.0-test releases) ready for prime time?)... We're periodically having this with some users (not sure what client they are using, but I am pretty sure it is MS Outlook) where the inbox is in near perfect shape except for some extra characters at the beginning of the file. POP or IMAP delivery fails with an error stating "File isn't in mbox format - Couldn't open INBOX". It looks like those characters are of a previous message that was not completely removed from the file, and those characters seem to throw everything out of wack.. It's easily correctable by removing the bogus characters from the beginning of the file, but that gets annoying quickly.. -Rich

[Dovecot] about filtering and dovecot
by Bram Mertens 24 Apr '05

24 Apr '05

Hi I would like to set up a local mailserver but I'm getting lost with all the available options. As I have already decided to use dovecot I hope someone here will be able to point me to the right docs/HOWTO's/... Here's my wish-list: 1) download mail from my ISP's POP3-server 2) scan with spamassassin 3) scan with ClamAV 4) filter messages (mailing lists/sender/...) 5) store messages in dovecot 6) be able to read messages on my desktop (where all of the above will be running) and on my laptop 7) be able to send messages (currently using evolution) from both my desktop and laptop so sent messages are stored in dovecot (the idea is to be able to see all sent messages on both PC's) I have already created a test-account om my ISP's POP3-server, installed and configured fetchmail and dovecot. Exim has been installed as well but I haven't touched it's configuration yet. Running fetchmail manually collects the mail and stores it in /var/mail/m8ram where dovecot finds it. So I would like to know (how to find out) how I can achieve 2), 3), 4) and 7). I have looked around and have discovered that there are many programs that can do some or all of this. But I haven't been able to figure out how to get them to work with dovecot. e.g. I don't understand what I would have to change to dovecot's config if exim or procmail or whatever moves certain messages to different folders (or even where these folders would be created). Perhaps I'm missing a HOWTO that explains all this, if so please let me know.

RE: [Dovecot] IMAP EXPUNGE disconnect/box hang - Fedora Core 2, Squirrelmail and Evolution
by Schettino, John Charles 24 Apr '05

24 Apr '05

Well, I just built and installed the 1.0 stable w/o tags version from source, and so far, it's not hanging/crashing the system - if this is the fix, I'm all over it :D Context: this is my problem: Correction: I'm running yum.log:03/07/05 05:48:28 Updated: dovecot 0.99.14-1.1.fc2.rf.i386 - Sorry about that. I'm a bit befuddled by this behavior. I've been using dovecot for close to a year, and recently the Fedora Core 2 Update: dovecot-0.99.13-4.FC2 build came in via yum. Since then I occasionally get this EXPUNGE disconnect error. When the error hits, the box does not crash but I can no longer log in*, nor start any new processes. I happen to have gkrellm running and I see a slow but steady climb in the # of processess. The only way to recover the box is to do a hard reset, as I cannot log in, nor su - to do a shutdown. In one case I happened to have a root shell open, and I still could not do a shutdown. Any ideas as to what I should do with this? As long as I don't expung everything is fine, but when I do expunge (move something or a filter runs in squirrelmail, or Action/Expunge in Evolution) sometimes it works fine, sometimes I get this error and a weird zombie state. It was all rock solid before this new version. Suggestions welcome - I don't seem to be getting any logging when it goes bad, perhaps I can up the log level? I'm more then happy to build the current dovecot from source, and if I should post this to some Fedora list, point me at it :D

[Dovecot] Dovecot LDA with sieve scripting
by Timo Sirainen 23 Apr '05

23 Apr '05

I also placed dovecot-lda-0.1.tar.gz in http://dovecot.org/test/. It's also in dovecot-lda module in CVS. It's based on the same deliver binary that exists in Dovecot's sources, but I've also plugged in CMU Sieve (mostly because it was the easiest one to plug in). The code could be much prettier, but it works anyway :) I think at some point I'm going to try to make the Sieve stuff a plugin on top of the normal delivery binary. (Dovecot in general should have some pretty plugin architecture, so you could just unpack them in some directory then do ./configure --with-builtin-plugins=quota-maildir,lda-sieve --with-external-plugins=sql,ldap,quota-sql) configure needs --with-dovecot=../dovecot-1.0-test68 option. So, usage goes like I mentioned in my previous mail (uhm. should put it into README): http://dovecot.org/list/dovecot/2005-March/006512.html Sieve script is assumed to be in ~/.dovecot.sieve file. It's automatically compiled to ~/.dovecot.sievec whenever timestamp changes. If it doesn't exist, mail is stored normally into INBOX.

[Dovecot] glue for HPUX
by rja＠surfeu.fi 23 Apr '05

23 Apr '05

Hi! Have anyone successed with hp-ux (how) ? I've compiled 0.99.14 with gcc-3.4.3 at hpux 11.11. I can telnet to port 143 and connection stays up, but I don't get any response back. It seems like dovecot "doesn't see" what I type in telnet. I tried to debug... # ps -ef | grep dovecot # gdb -tui -p 17185 /usr/local/sbin/dovecot Attaching to program: /usr/local/sbin/dovecot, process 17185 [ No Source Available ] warning: reading `r3' register: No data 0x77faff30 in _poll_sys+0x10 () from /usr/lib/libc.2 (gdb) up #1 0x77fba9ac in poll+0x6c () from /usr/lib/libc.2 (gdb) up |163 ret = poll(data->fds, data->fds_pos, msecs); >|164 if (ret < 0 && errno != EINTR) |165 i_warning("poll() : %m"); #2 0x14310 in io_loop_handler_run (ioloop=warning: reading `r8' register: No data 0x0) at ioloop-poll.c:163 (gdb) This works fine... # MAIL=mbox:~/mail /usr/local/libexec/dovecot/imap * PREAUTH [CAPABILITY IMAP4rev1 SORT...

[Dovecot] password_verify in test67 with ldap
by Thomas Hummel 23 Apr '05

23 Apr '05

Hello Timo, your patch introducing pass_attr_names and user_attr_names fixed the problem of the 'shared' attr_names member of [passdb|userdb]_ldap_conn as I answered in the relative thread. Now I think there is a problem while comparing user-provided and ldap-provided passwords causing a false 'password mismatch' situation, while using PLAIN mechanism with LDAP authentication. As a matter of fact, the user provided by the user, as read in the 'mech_plain_auth_continue' function is passed as an argument in the 'auth_request_verify_plain' function which, in turns pass it to the function pointed to by 'passdb->verify_plain' (that is 'ldap_verify_plain') which doesn't use it [instead maybe of setting the 'passdb_ldap_request' 'password' field with it ?]. So once back from the LDAP request, when in 'handle_request' we call 'password_verify', the password we try to match against the one read in the LDAP db is null. Did I get it right ?

[Dovecot] feature request: login in process title
by Marten Lehmann 23 Apr '05

23 Apr '05

Hello, I'm a bit afraid of users, the might slow down the server because of search requests to the imap-server on very large mailboxes. Even with a performant index, this could cause a lot of cpu and i/o-load. Is it possible to include the login-name in the imap process, so that a "ps ax" doesn't just give "imap", but e.g. "imap test(a)example.com"? Maybe it's of general interest to see in the title at which stage an imap-process is working. Regards Marten

[Dovecot] creating subfolders without preceding inbox wanted?
by Marten Lehmann 23 Apr '05

23 Apr '05

Hello, today I accidentally created a subfolder "Trash" instead of INBOX.Trash. No error was given, the creation lead to the folder ".Trash". If I know this folder, I can also select it. But a "list * * " doesn't show the Trash folder. How could I ever find this folder by the imap-procotol if I don't know it's name? Is this the correct behaviour? Or shouldn't imap simply disallow the creation of such folders, but only with preceding "INBOX."? Regards Marten

[Dovecot] IMAP EXPUNGE disconnect/box hang - Fedora Core 2, Squirrelmail and Evolution
by Schettino, John Charles 22 Apr '05

22 Apr '05

Correction: I'm running yum.log:03/07/05 05:48:28 Updated: dovecot 0.99.14-1.1.fc2.rf.i386 - Sorry about that. I'm a bit befuddled by this behavior. I've been using dovecot for close to a year, and recently the Fedora Core 2 Update: dovecot-0.99.13-4.FC2 build came in via yum. Since then I occasionally get this EXPUNGE disconnect error. When the error hits, the box does not crash but I can no longer log in*, nor start any new processes. I happen to have gkrellm running and I see a slow but steady climb in the # of processess. The only way to recover the box is to do a hard reset, as I cannot log in, nor su - to do a shutdown. In one case I happened to have a root shell open, and I still could not do a shutdown. Any ideas as to what I should do with this? As long as I don't expung everything is fine, but when I do expunge (move something or a filter runs in squirrelmail, or Action/Expunge in Evolution) sometimes it works fine, sometimes I get this error and a weird zombie state. It was all rock solid before this new version. Suggestions welcome - I don't seem to be getting any logging when it goes bad, perhaps I can up the log level? I'm more then happy to build the current dovecot from source, and if I should post this to some Fedora list, point me at it :D

I have built Dovecot 1.0 test 67 under MACOSX. But I can not find any tutorial on how to setup it. Please allow me to explain my need. I want to setup a local imap server, and then import all my email from Mail.app and Gnus into it. Thus I can choose to read emails with any client. It's only a single user environment. Could anyone instruct me if there is any tutorial for Dovecot MACOSX setting? Thanks in advance.

[Dovecot] Disable multiple POP3 logins

21 Apr '05

Hi, With some POP3 servers, when you login more than once, the POP3 server says "Err: multiple login". How can I achieve that with dovecot ? For example: I login to my POP account that is hosted by the ISP: $ telnet pop.x.com 110 Trying x.x.x.x... Connected to pop.x.com (x.x.x.x). Escape character is '^]'. +OK <25628.1113981451@bne022mfe> USER mb13536d +OK PASS testcase +OK LIST +OK 1 4608 . STAT +OK 1 4608 While that pop3 login is still active, I run another telnet session to login again to the same account. $ telnet pop.x.com 110 Trying x.x.x.x... Connected to pop.x.com (x.x.x.x). Escape character is '^]'. +OK <11709.1113981546@bne021mfe> USER mb13536d +OK PASS testcase -ERR multiple login Connection closed by foreign host. Thanks, John

[Dovecot] message status changed from new to old on read
by Andrew Pimlott 21 Apr '05

21 Apr '05

Hi. I'm new to IMAP, but just tried uw-imapd and then dovecot in conjuction with offlineimap. I'm using Debian package version 0.99.14-1 and have my mail in mbox format. One of the first things that annoys me about both programs is that as soon as you read a mailbox over imap, the imapd changes all "new" messages to "old". It seems to have the assumption that the IMAP client is "reading" the messages, but particularly in the case of offlineimap, this assumption is not justified: I might not read the message on the client on which I've just synced, I might read it on the server or another client. So I would like dovecot to leave the mailbox alone, and leave it up to the client to write any changes to message status. Is there any option to dovecot that would accomplish this? While experimenting, I noticed that dovecot sometimes doesn't notice changes to the status made directly on the server. For example, if I create new mbox mailbox with one message (initially "new"), and access it with imap (using mutt in this example), it shows up "new" in the client. When I next access it with imap, it shows up "old", because dovecot modified the status as described above. If I then run mutt directly on the mailbox and change the status back to "new", then access it with imap, it still shows up "old". If I then remove the .imap directory containing the caches, it is back to "new". I assume that dovecot is supposed to pick up changes made directly on the server, right? Thanks for your help, Andrew

[Dovecot] minimial maildir++ quota for dovecot-0.99
by David Harris 21 Apr '05

21 Apr '05

Hello, I'm using dovecot-0.99.14, and I wonder if anyone has created patch for *minimal* Maildir++ support. By minimal Maildir++ support, I mean the following: (1) New messages created by dovecot will include the ,S=nnnnn string in the unique identifier so that Maildir++ clients don't have to stat the file to know the size. (2) Dovecot will append to the maildirsize file when a message is deleted or added. If maildirsize gets larger than the 5120 limit, then just delete it and let someone else recalculate the quota. My goal isn't full Maildir++ support in dovecot, but just to make it play nicely with my Maildir++ aware delivery agent. (If someone has full Maildir++ support, I'd be glad for that too!) If what I describe above doesn't exist, I am interested in paying someone to make this quick patch. E-mail me off list if you are interested. Thanks, David

[Dovecot] dovecot ssl problem
by Alexander Heuer 20 Apr '05

20 Apr '05

Hi there, I am having a weird problem with dovecot and ssl. If I am accessing the dovecot imap server with for example sylpheed-claws or evolution, everything works fine. If it is accessed via windows either by outlook or thunderbird, we get occassional timeouts. It's working fine for a few hours, then for 5 to 20 minutes, every attempt to connect from the outside results in "Connection to server timed out". Added to that, the problem only arises, if a direct SSL connection to Port 993 is used. Using Sylpheed with STARTTLS to Port 143 from the outside works fine as well. It's not a firewall Problem, since port 993 and 143 are open, the config files have been checked over and over for 2 weeks and are good as well. Dovecot log says: imap-login: Apr 20 13:26:05 Warning: SSL_read() syscall failed: Connection timed out [83.104.224.142] Doing uber verbose output doesn't bring up any extended information, syslog stays clean as well. The Problem is not directly reproducable by a certain action, it just arises from time to time. There can be 3 working days without problems, or 6 timeouts > 20 minutes within one day. System is Debian Sarge unstable with a custom 2.6.10 Kernel. During the timeouts, mail is still received and put into the users mailboxes by exim, it's just that you cannot access the imap server for approx 20 minutes. Dovecot version is 0.99.14 Regards Alexander Heuer

[Dovecot] SORT using cached filesystem modtimes
by Emmett Lazich 18 Apr '05

18 Apr '05

Timo or anyone, This may be a bug or maybe a design decision. Either way I am curious to hear comments. Why do the dovecot-0.99.14 server's .imap.index files contain a cached copy of each message's date and time as supplied by the filesystem, as opposed to the date and time found in each message header? When testing various imap clients (eg. tbird-1.0.2, evolution-2.0, outlook2003, squirrelmail-1.4.4) I was intrigued by the behaviour of message date sorting. I toggled on/off the use of server side SORTing in some imap clients, then started forcing rebuilds of .map.index files, and eventually came to the above conclusion. For normal dovecot server side processing, this condition (if I am correct) may not be a problem, but if someone was to deposit a bunch of maildir files firstly into an imap account (bypassing dovecot), and if this person (eg. me) did not preserve the filesystem/inode file attributes. Then dovecot appears to cache the "wrong" data. What happens then is that some imap clients can display wrong date+times in the message lists, and some imap clients find that server side SORTing does not work. Keen to hear thoughts/opinions. -Emmett

[Dovecot] Dovecot causing hanging on random folders...
by Rick Flower 17 Apr '05

17 Apr '05

I've been using the 1.0 test series (currently 1.0test 67 and before that 1.0-test59) and both exhibited this issue.. I use Thunderbird and will open one or two of my nested Maildir folders via imap and find that it goes out there trying to open the folder (according to the messages that Thunderbird claims) and it never comes back.. I've attached to the various dovecot processes to see what their doing and they appear to be waiting for things to do -- e.g. not working on anything in particular.. The only way to fix this is to quit Thunderbird and restart it.. I see this about 2-3 times a day.. I'd love to track it down.. I've seen this on Fedora Core 1 (i386 server) and also on a PPC Linux system running an older kernel (on a Buffalo Linkstation if you know what that is).. Below is the current set of dovecot processes running on my FC1 box : [rickf@srv1 dovecot-1.0-test67]# ps aux | grep dove root 748 0.0 0.0 3380 720 ?

All my mail accounts are virtual accounts that come from pam with the following configuration in auth_default: passdb = pam userdb = static uid=5000 gid=5000 home=/var/mail/vhost/example.com/%n mail=/var/mail/vhost/example.com/%n for a user foo, if the directory /var/mail/vhost/example.com/foo already exists, then all is ok, but if the directory doesn't exists, it seems dovecot is unable to create it "on the fly". I get the following error message: Failed to create storage with data: /var/mail/vhost/example.com/foo i'm quite sure it is not a permission related problem (i made /var/mail/vhost/example.com world writable to be sure). I'm currently trying to understand the maildir code... But could someone tell me if the maildir directory should exist for dovecot to work ? In the case that the answer is yes, i would say in advance that it's a problem for sites hosting a lot of virtual users, since it means that these users must receive at least one mail for their mail account to work correctly (i use postfix as MTA, and if the user's maildir doesn't exist, postfix takes care of creating it). I'm not very fond of solutions with scripts taking care of creating users. Thanks in advance for your answers :) -- \|||/ (o o) Matthieu Imbert ooO-(_)-Ooo------------------------------------------ équipe administration réseau et systèmes Ecole normale superieure lettres et sciences humaines 15, Parvis René Descartes BP 7000 69342 LYON cedex 07 tél 0437376127, secrétariat 0437376122 fax 0437376123 contact équipe réseau et systèmes <reseau(a)ens-lsh.fr> contact personnel <matthieu.imbert(a)ens-lsh.fr> -----------------------------------------------------

I've been seeing a lot of these in my logs: dovecot: Apr 11 17:48:24 Error: IMAP(fenner): Lost transaction log file /home/f/fenner/Maildir/dovecot.index.log seq 3 dovecot: Apr 11 17:48:24 Error: IMAP(fenner): Lost transaction log file /home/f/fenner/Maildir/dovecot.index.log seq 3 dovecot: Apr 11 17:48:24 Error: IMAP(fenner): Lost transaction log file /home/f/fenner/Maildir/dovecot.index.log seq 3 dovecot: Apr 11 17:48:24 Error: IMAP(fenner): Lost transaction log file /home/f/fenner/Maildir/dovecot.index.log seq 3 dovecot: Apr 11 17:48:24 Error: IMAP(fenner): Lost transaction log file /home/f/fenner/Maildir/dovecot.index.log seq 3 dovecot: Apr 11 17:48:24 Error: IMAP(fenner): Lost transaction log file /home/f/fenner/Maildir/dovecot.index.log seq 3 dovecot: Apr 11 17:48:24 Error: IMAP(fenner): Lost transaction log file /home/f/fenner/Maildir/dovecot.index.log seq 3 dovecot: Apr 11 17:48:25 Error: IMAP(fenner): Lost transaction log file /home/f/fenner/Maildir/dovecot.index.log seq 3 dovecot: Apr 11 17:48:25 Error: IMAP(fenner): Lost transaction log file /home/f/fenner/Maildir/dovecot.index.log seq 3 dovecot: Apr 11 17:48:25 Error: IMAP(fenner): Lost transaction log file /home/f/fenner/Maildir/dovecot.index.log seq 3 dovecot: Apr 11 17:48:25 Error: IMAP(fenner): Lost transaction log file /home/f/fenner/Maildir/dovecot.index.log seq 3 Agent is Apple Mail. Previously removing the indexes and letting them rebuild fixed the issue. Now I've had to restart the server and remove the indexes.

[Dovecot] Invalid mbox file /var/spool/mail/username: No such file or directory
by Obantec Support 17 Apr '05

17 Apr '05

Hi dovecot-0.99.11-1.FC3.4.i386.rpm on FC3 when i create a user account with pop3 email i find that if i don't send and email to the account (so that sendmail creates the file under /var/spool/mail/testuser) where "testuser" is the users username. If the user logs in with Outlook or Outlook express they get an error and maillog shows. Apr 11 14:18:58 proteus2a pop3(testuser): Invalid mbox file /var/spool/mail/testuser: No such file or directory Apr 11 14:18:58 proteus2a pop3(testuser): Failed to create storage with data: mbox:/var/spool/mail/testuser if "testuser" file does not exist it would be better if Dovecot created an empty file IMHO. as a temp fix i now fire off emails to new accounts to avoid this.

Here's a new one. It just started with the latest (April 8) CVS version. In index-mail-headers.c, line 622: fields = t_new(struct mail_cache_field, count); count is 0 I'm seeing this with several mailboxes. We're using mbox.
