[Dovecot] Error in rename uidlist while fetching through pop3
by James Berry 03 May '05

03 May '05

My dovecot server seems to randomly begin giving errors to pop3 users who try to fetch their email. Once this begins, they see no more new mail, though the mail is in cur. Running: dovecot-stable 20050501, Mac OS X 10.3.9 Log entries like this: May 2 19:35:18 caddy dovecot: pop3-login: Login: kim [24.22.16.169] May 2 19:35:18 caddy dovecot: POP3(kim): rename(/Users/kim/Maildir/ dovecot-uidlist.lock, /Users/kim/Maildir/dovecot-uidlist) failed: Input/output error May 2 19:35:18 caddy dovecot: POP3(kim): file_dotlock_replace(/Users/ kim/Maildir/dovecot-uidlist) failed: Input/output error Is this a known problem, and/or is there a known way to recover from such a situation? I'm managed to throw out the uidlist, but that means they get a whole dump of new mail. -jdb

[Dovecot] How to try dovecot-lda
by Joakim Verona 02 May '05

02 May '05

Hello, I'm interested in trying the dovecot-lda with sieve support. What would be the proper way to test it? I'm currently using a Fedore core 2 server, with spamassassin and procmail. To get the same effect with dovecot-lda, would I put a line like this in my .forward? spamassassin|dovecot-lda I'm just guessing, so please correct me if im wrong. Im thinking of setting up a separate mail account and copy my mail there to test the ported procmail to sieve recipies also. -- Joakim Verona www.verona.se

[Dovecot] disabling indexes?
by Marten Lehmann 02 May '05

02 May '05

Hello, I recently had the problem, that an index was corrupt. Thus, messages haven't been listed (talking about POP3), but still remained in the filesystem. As there is no SEARCH-command in POP3, dovecot didn't notice that the index is corrupt and didn't rebuild it. The problem is, that a user can't delete messages through POP3 which aren't listed by dovecot. If the maildir size increases, the arrival of new messages will be blocked because the mailbox is full. And the user has no chance to delete it. Regards Marten

[Dovecot] Blank lines in mailboxes
by Jakob Curdes 30 Apr '05

30 Apr '05

Hello, we use dovecot on a regular basis. Sometimes I end up with a user telling me he does not get mail. When I look after the problem, I always find leading blank lines in the mbox file. We are using postfix with dovecot and amavisd as spam scanner. Amavisd never accesses the mbox files directly so this can be ruled out. I suspected procmail but now it happened also with accounts where no procmail is active. I found only a list thread where this happened always, i.e. it was a configuration error. (Meaning the mailbox was correct but dovecot would not read it). Here ist is only occasionally and therefore hard to track . Does anybody have the same problem or has hints to a solution ? We are running postfix 2.1.4 and dc 0.99.10.6 ; just now I am upgrading to pf 2.2.2. and dc 0.99.14. Yours, Jakob Curdes

[Dovecot] Fresh Dovecot Install
by GPL 29 Apr '05

29 Apr '05

Working on an RH9 box. Did not use yum. Downloaded the "dovecot-stable-latest.tar.gz". Uncompressed it, downloaded and installed gcc. Ran the following: ./configure make sudo make install Seemed to have done its thing. I'll admit I am not well versed in using "make" or compiling anything. When I install I usually use yum on fedora machines. This one being an RH9 machine I have plugged yum into the fedora legacy project and it did not let me install dovecot via yum. So I opted for this route. Regardless, if I run 'which dovecot' I see "/usr/local/sbin/dovecot" However now I do not seem to be able to see it run. I get nothing when I: rpm -qa | grep dovecot ps aux | grep dovecot service dovecot status SO AM HAVE MISSED SOMETHING! Is there another script I need to run? Suggestions welcome. Thanks, George

[Dovecot] dovecot 0.99.xx to 1.0-stable how-to?
by Rich West 28 Apr '05

28 Apr '05

I realize that there have been some big changes in features and configuration file settings between 0.99.xx and 1.0-stable, so when I went to perform an upgrade on our testing server, I carefully combed through the configuration files and matched up everything I could. I fired up dovecot-1.0-stable and was pleased to see that it was happily running. I attempted to connect to it, and discovered that it wasn't listening to any ports.. then I realized that the app had crashed due to a typo in the config file (oops). Fixed that, started it up, and it was happily running and listening. However, it wouldn't authenticate any users.. Backing down to the 0.99.14 version that we had installed allowed for authentication (against ldap) to work just fine.. Is there anything that I should be looking for within the dovecot-1.0-stable that is dramatically different in regards to user authentication? -Rich

I don't know enough to say either way. Maybe I'll take a closer look after I've finished delving into Sun's RBAC. As for the code changes, from memory the UID checking stuff is all in the one place ( in 0.99.14 it seems to be src/lib/restrict-access.c ). I'm not sure about 1.0... we'll move to that when we can have custom flags :) -- Curtis

[Dovecot] cutting everything after @
by Juraj Bednar 27 Apr '05

27 Apr '05

Hello, I am migrating one server to dovecot. The only problem is, that users have logins with @domain as part of their user name. I want to use pam auth (for other reasons, if only for dovecot, I would use mysql, but I need the same password db to be used for other services, like samba). Is there a way to allow this type of login? Just cut everything beginning with @. I can change the source code, but then I don't get nice automatic upgrades. Or can this be done easily with PAM? Thanks, Juraj.

[Dovecot] Shared mailboxes and accessing MailDir not through IMAP
by Steffen Kaiser 27 Apr '05

27 Apr '05

Hello, I'm testing Dovecot that is part of Debian/sarge (v0.99.14-1). So far so good. I have migrated some mailboxes for testing with success and seems that everything works fine. One thing I do not figure out is, what to do about shared mailboxes, which are the very reason of searching for an alternative IMAP server, The Wiki states that there is some sort of shared mailboxes, based upon symlinks. Well, but since which version actually?? The Changelog stops at 2003-11-08 21:12 ? What I need is a mailbox (maildir) for a contact address (not a real shared mailbox, but several users shall be able to read a mail and delete it after processing). For this, one needs write permission to the mails therein only, the MDA takes care of to make the mails readable for the group. It would be good to see, if somebody had answered a mail already, but that's not required. What I tried is this: I setup all Unix-permissions of the folders (. cur new tmp: u=rwx,g=srwx) and their parents (u=rwx,g=x). Then I placed a symlink into the maildir of all users. Each user caches the INDEXes into an individual /var/ directory, not in the maildirs themselves. (BTW: I wonder why I need to give the group write permission to the base directory '.'). The mailbox shows up and is read-write. Now I wonder, what impact I'm to expect here? Esp. "The only problem is that currently everyone's message flags would be shared as well." (quote from a message of a thread taken from the Wiki) Then there is http://dovecot.org/pipermail/dovecot/2003-March/001113.html the third item will apply to my situation, I guess. MailDir is (sort of) expected to be read by mutt directly, for instance. Because the mailboxes are located within the users home directories, some of them do this. Do this item mean that Dovecot is NOT expecting that mails are deleted in any other way than through itself? Otherwise Dovecot would find a change in the mailbox and rebuilt the index file regardless whether the change had been originated by another IMAP client or by directly manipulating the maildir. Bye, -- Steffen Kaiser

[Dovecot] local users + virtual domains
by Micha Silver 27 Apr '05

27 Apr '05

I'm redesigning our mail server which holds several hundred mailboxes - most are local system users and some are virtual domains that we host. I understand that the 1.0x stable release allows for multiple auth mechinisms, so that I could use both PAM for local users and a passwd-file for the virtuals. If I want to stick with 0.99x can I mix and match in a single passwd-file the username/passwd for both local and virtual users? In dovecot.conf I'd have something like: default_mail_env = maildir:%h/Maildir auth-userdb = /etc/dovecot/passwd-file auth-passdb = /etc/dovecot/passwd-file then in passwd-file I'd enter: # local users localuser1:<passwd>:501:501::::: localuser2:<passwd>:502:502::::: ... #virtual domains virt1(a)example1.com:<passwd>:5001:5001::/var/vmail/%d/%u:/bin/false::INBOX=/var/vmail/%d/%u/Maildir postmaster(a)example1.com:<passwd>:5001:5001::/var/vmail/%d/%u:/bin/false::INBOX=/var/vmail/%d/%u/Maildir virt1(a)example2.com:<passwd>:5001:5001::/var/vmail/%d/%u:/bin/false::INBOX=/var/vmail/%d/%u/Maildir postmaster(a)example2.com:<passwd>:5001:5001::/var/vmail/%d/%u:/bin/false::INBOX=/var/vmail/%d/%u/Maildir ... Would this combination work? Thanks, Micha

We're using procmail to deliver mail and dovecot as the imap server. Imap access is sometimes through UW-imap on the same mailboxes. We keep the index files on the NFS server and are using mbox format. I am only running this on one server at this point, so you could see other problems if it is run on multiple servers. Procmail is run on several servers. We're probably testing around 50 mailboxes, some quite large. I haven't seen any corruption of the mboxes and some of them get hit pretty hard. >From my experience, I wouldn't call it "unreliable". I have this setting in the config: mmap_disable = yes I haven't tried using mmap yet... The server is Linux, kernel 2.6.x and the NFS server is a NetApp. Make sure that NFS locking is working. Todd

[Dovecot] Track when user last checked mail
by Del Stoliker 27 Apr '05

27 Apr '05

First off I've just got to say thanks. We just upgraded from UW to Dovecot migrating from mbox to maildir. Wow, what a difference! Load average used to hang around 5.0 during business hours and could get up to 20+ on a bad day. Now we rarely break 1.0! I'm wondering if there's a way to keep track of the last time a user checked their email and whether they checked it using POP or IMAP. We're trying to gather statistics on what protocols our users use and find accounts that haven't been checked for a long time. We used to be able to do some of this with the finger command and the user's mbox. I found a script called "mfinger" that works better with Maildir, but it's designed for Courier. Any ideas? Thanks!

[Dovecot] docecot and procmail?

Is dovecot still considered unreliable when combined with NFS? Is this true for mbox only, or Maildir as well? If dovecot Is still considered unreliable with NFS, how about having a dovecot mode that would chain into procmail for delivery, so that dovecot doesn't (necessarily) have to reinvent that wheel? Thanks!

[Dovecot] Why is "UIDVALIDITY changed" fatal?
by Chris Wakelin 27 Apr '05

27 Apr '05

I've got several users testing Dovecot IMAP at the moment, but some of them are also accessing their mail via UW-IMAP at other times. (I've warned them about accessing the same folder simultaneously via UW-IMAP and Dovecot!) In addition, we have special folders "AutoSpam" and "Trash" that pruned using Washington's "mailutil" automatically every so often. Of course, Dovecot's indexes will become invalid in such cases, but they seem to get rebuilt automatically OK. However, in some cases UW-IMAP seems to change the UIDVALIDITY value (not sure why!) and when Dovecot tries to sync it notices this and gives up with a fatal error on opening that folder. Opening the folder a second time is then OK. I was wondering why Dovecot can't just rebuild the indexes silently in such cases (which seems to be done by returning "0" from the mbox_sync_loop() routine)?

[Dovecot] 1.0-stable update
by Timo Sirainen 26 Apr '05

26 Apr '05

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] Limiting IP range access

[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] 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

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

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] How to setup dovecot under MACOSX?
by CHENG Gao 22 Apr '05

22 Apr '05

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] maildir creation
by Renzetti Federico 22 Apr '05

22 Apr '05

Hi all, this is my first post to the list and sorry for my english. I have a mail server based on qmail+dovecot+ldap with virtualdomains and maildir stored in /var/vmail/<DOMAIN>/<USERNAME>/Maildir. When I create a user on LDAP I don't create maildir too. So if I log-in with dovecot (143,110) I hope dovecot creates maildir for users but this is not I get: maildir are not created... dovecot.conf .... default_mail_env = maildir:/var/vmail/%d/%n/Maildir .... There is a way to create automatically maildir for users? Thanks all. -- Renzetti Federico System/Network Administrator RedHat Certified Engineer Fabaris S.r.l.

I'm dying to use the 1.0 capability to use more than one mysql user pasword database. However, I'm too chicken to use 1.0-test in a production environment. Does anyone know if there is a planned release date for 1.0? Or can anyone say how risky it is to use 1.0-test?

[Dovecot] Disable multiple POP3 logins
by Jesus Salvo Jr. 21 Apr '05

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] attr_names in test67

[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 ?

[Dovecot] Failed to create storage with data:
by Matthieu Imbert 17 Apr '05

17 Apr '05

Hi, i'm using dovecot-1.0-stable. 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> -----------------------------------------------------

This doesn't happen to other folders I try to access via IMAP, only my INBOX. Since this only seems to affect Evolution and not pine, I don't know whether this is technically a bug in dovecot or Evolution. I guess that's up to the RFC, which I haven't read all the way through. Anybody got an idea about how to fix this or what's causing it? (Please CC me directly on any replies, I'm not subscribed to this mailing list) Thanks, --Dennis Lambe, <malsyned(a)gmail.com> P.S. Is there a way to get a session transcript out of dovecot? It would save me a fair bit of perl hackery.

[Dovecot] Upcoming configuration file changes
by Timo Sirainen 17 Apr '05

17 Apr '05

For those who might be interested. Comments welcome. A few weeks ago I had started redesigning how Dovecot handles configuration files. I wrote a new parser and converted dovecot-auth to use the new way. Today I finally managed to convert imap process as well, which wasn't that easy because I didn't want mbox/maildir-specific settings to be hardcoded in any common code. So, the changes will be: - Dovecot master process will need a new completely different configuration file which tells what processes to run and their uids/chroots/memory limits. Very much like Postfix's master.cf. I'm not sure about its format yet (suggestions welcome), but maybe something like it's already: process imap-login { executable = /usr/lib/dovecot/imap-login chroot = /var/run/dovecot/login uid = dovecot vsz_limit = 32M } ... Hopefully after these changes the master process will become very small and simple. - One of the processes will be a configuration process, which is the one that reads and parses the configuration for non-master processes. The default configuration file format will be pretty similar to what we have now, but it can of course be replaced with SQL backends and whatever. Config process will listen in some unix socket waiting for requests from other processes, which connect to it just after they start up and maybe also sometimes later (eg. to get user/IP-specific settings when a new client connects). - The data that config process sends and what other processes parse is based on simple key=value pairs, so it's possible to still store and parse them from environment if needed. Also it makes it possible to override settings from command line (eg. imap -o mail_debug=yes) or give user-specific settings in userdb. Here's an example: # config process reads something like: mmap_disable = yes namespace foo { type = private separator = / mbox { dir = ~/mail mbox_read_locks = dotlock } } # sends out: mmap_disable = yes namespaces = foo namespaces_foo_type = private namespaces_foo_separator = / namespaces_foo_mbox = 1 namespaces_foo_mbox_1_dir = ~/mail namespaces_foo_mbox_1_mbox_read_locks = dotlock - Config process should verify that all given settings are valid so that typos are noticed. This may not be that easy because the setting definitions are distributed all around the source code. I think there needs to be at least a (Perl) script that finds out all the setting definitions and writes them to some all-settings.c for config process so it knows them. Settings for plugins are more difficult though.. Should they somehow be marked in config file that they're plugins (plugin foo { .. })? Or maybe config process could dynamically load all the plugins itself and request their setting definitions?

[Dovecot] Logwatch

Having FC3 systems and utilizing Dovecot, I have come to rely on some of the information I get from the daily logwatch run.

[Dovecot] comparision with other imap servers and folder sharing
by Emmett Lazich 15 Apr '05

15 Apr '05

Some praise: Timo, I must say I am super impressed with this product. I do free support a few good friends with small businesses running Linux servers (a mix of RH9, Suse9.2 and gentoo) that I dropped as email and samba servers. I found UW-IMAP to be terrible in every way except that using mbox is sometimes nice for old s/w tools. No need for details re UW-IMAP problems. In early 2004 I found courier-imap to be vastly better behaved than UW-IMAP and also much faster once large folders were open. DJB's Maildirs seemed cool, and postfix likes them too, and mb2md-3.20.pl worked great . So everything seemed good and certainly was better. But courier cannot cope with large imap accounts (eg. millions of messages and a few GBytes) where courier-imap grinds to a halt on the initial folder scanning. Cyrus just looks like a big evil beast that needs too much time to learn. Four days ago, this lead me to dovecot. The performance, reliability, configurability of dovecot is amazing. Timo, I think you could give yourself more credit on something important when selling Dovecot. You write that Dovecot "does not support shared folders". This might turn away some people considering Dovecot. People whom like me do not have/want a good understanding of the imap protocol. I believe you mean that Dovecot does not support shared folders in the technical imap sense of shared namespaces between separate imap accounts. Since Dovecot works beautifully when sharing folders via logging in with the same username more than once. Plus your documentation and config notes imply that this is no problem. IDLE and fcntl locking works great for me. Thank you and good luck! -Emmett

[Dovecot] test67 ldap_connection

As 'passdb_ldap_conn' and 'userdb_ldap_conn' are of the 'ldap_connection' type and since the 'db_ldap_init' function returns the existing ldap connection if it exists, the 'passdb_ldap_preinit' and 'usedb_ldap_preinit' will call the 'db_ldap_set_attrs' function on _the same_ 'ldap_connection' object. - So when the 'db_ldap_search' function is called from the 'passdb-ldap.c:ldap_lookup_pass function, the 5th argument (passdb_ldap_conn->attr_names) will point to the 'user_attrs' instead of the 'pass_attrs', since userdb_preinit will have already been called. - I've also noticed the use of the 'attr_map' hash to store the attribute/value pairs, but since it doesn't seems to be used when calling 'ldap_lookup_pass', I guess the problem is somewhere else. Can someone give me a clue ? Has someone successfully set up dovecot-1.0-test67 on a similar configuration ? thanks -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] Syslog, Dovecot, and LogWatch
by Rich West 12 Apr '05

12 Apr '05

At what level does Dovecot log to syslog? UW-IMAP uses local6.debug to log to syslog, but it doesn't seem that dovecot does the same.. (the file I defined for UW-IMAP's output hasn't received anything since I moved over to Dovecot? Also, has anyone managed to get LogWatch and Dovecot to play nicely together? I noticed that LogWatch no longer gives any statistics on the imap usage since I shut down UW and went full blast with Dovecot.. -Rich

[Dovecot] Index(?) problem under OpenBSD
by Gaby vanhegan 12 Apr '05

12 Apr '05

Hi, My apologies if this has been mentioned before, I haven't pulled up a google search yet. I run Dovecot from the package under OpenBSD 3.6 (dovecot-0.99.10.8). The problem I have is that occasionally dovecot corrupts an index file (I think), which causes the process to gradually creep up in usage, until it hits 99%, where it stays, without quitting. If I then fire up my mail client later on, it does the same thing. Doing this two or three times results in 3 processes, all at 33%, and a load of 100 on the server. The problem is resolved by deleting all the index files in my Maildir. If this doesn't solve the problem, then duplicating my Maildir and using the new copy, after deleting all the index files, fixes the problem. But these only work for a while, and the problem rears it's head with other users as well, so I need a fix. Has anybody else suffered this problem? Is there a fix in a more recent version? Is it OpenBSD specific? What can I do to help diagnose the problem? Should I turn of indexes? Upgrade to the latest version? Some example errors from my logfile: imap(gaby): Apr 11 15:32:37 Error: Corrupted index file /home/gaby/Maildir/.INBOX/.imap.index: Wrong messages_count in header (261 != 382) imap(gaby): Apr 11 15:32:37 Error: Corrupted index data file /home/gaby/Maildir/.INBOX/.imap.index.data: used_file_size larger than real file size (142368 vs 10264) imap(gaby): Apr 11 15:32:44 Error: Corrupted index file (in-memory index for /home/gaby/Maildir): UIDVALIDITY changed in uidlist imap(gaby): Apr 11 15:36:12 Error: Timeout while waiting for release of shared fcntl() lock for index file /home/gaby/Maildir/.Work.LTSN/.imap.index imap(gaby): Apr 11 16:21:27 Error: Timeout while waiting for release of shared fcntl() lock for index file /home/gaby/Maildir/.Archive.Trash-20050308/.ima imap(gaby): Apr 11 16:25:02 Error: Timeout while waiting for release of shared fcntl() lock for index file /home/gaby/Maildir/.Archive.Trash-20050407/.ima Gaby -- Uganda Maximum - Enemy of the English Thrust gaby(a)vanhegan.net http://weblog.vanhegan.net

[Dovecot] Namespace prefix not ending with separator
by Chris Wakelin 11 Apr '05

11 Apr '05

I'm still battling my way through using hidden namespaces to hide the change from UW-IMAP to Dovecot 1.0-stable from my users. The latest problem is that some (probably many) users have their IMAP folder prefix set to "~/mail" rather than "~/mail/". I have hidden namespaces with prefixes "~/mail/", "~%u/mail/" and "mail/". LIST "~/mail" "*" returns nothing, so I've tried adding another namespace for "~/mail". Now LIST "~/mail" "*" returns * LIST (\NoInferiors \UnMarked) "/" "~/mailtest1/test1-2" * LIST (\NoInferiors \UnMarked) "/" "~/mailtest2" * LIST (\NoInferiors \UnMarked) "/" "~/mailtest3" whereas UW-IMAP returns * LIST (\NoInferiors \UnMarked) "/" ~/mail/test1/test1-2 * LIST (\NoInferiors \UnMarked) "/" ~/mail/test2 * LIST (\NoInferiors \UnMarked) "/" ~/mail/test3 I wonder whether LIST should insert an extra namespace separator in such cases? Having said that, it seems to work, except it may cause problems with folder subscriptions, which I've had to hack in order for them to be compatible with UW-IMAP (i.e. to store them as "~/mail/test1" etc.) Best Wishes, Chris --+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+-- Christopher Wakelin, c.d.wakelin(a)reading.ac.uk IT Services Centre, The University of Reading, Tel: +44 (0)118 378 8439 Whiteknights, Reading, RG6 2AF, UK Fax: +44 (0)118 975 3094

[Dovecot] imap segfault in mail-index-sync.c
by Todd Burroughs 10 Apr '05

10 Apr '05

Our support team seems to have caused another crash. They treat this mailbox like a shared one, so there may be a few people accessing it at once. They are mostly using dovecot, but some could be using uw-imap. These are the only two ways that this box is accessed. I know that this doesn't really work with mbox, but it doesn't appear to corrupt the mailbox. It seems to be a good stress test... In this case, it looks like several of them are logged in at once. Here's the log entry and backtrace of the imap process which segfaulted. I'll put a section of logs covering this time at the end, in case it helps.

[Dovecot] Authentication and the wrong mailbox?
by Rich West 10 Apr '05

10 Apr '05

I just migrated from UW-imap to dovecot last night. After some tweaking of the dovecot.conf file, disabling xinetd's entries, firing up the dovecot daemon, and copying the .mailboxlist to .subscriptions for all users, things looked to be going just fine! I received a call this morning from a user stating that they had all of *my* emails in *their* inbox! They don't know when it happened as their machine POP's email off every 5-10 minutes or so, but we were able to isolate it to a 8hr period last night. Further investigation showed that at some time through the evening, dovecot freaked out during the authentication phase and for some bizzare reason, when the user connected via POP3, they were able to download all of my inbox! Additionally, by the time I was looking in to it, NO users could authenticate via dovecot, and, hence, no one had access to email. Restarting dovecot resolved the issue, but I have my doubts about it being truly resolved. I'm going to run some tests (what little I can think of), but this is the first time I have ever experienced a situation such as this. One thing for UW is that this situation never happened, and I've only had dovecot running for about 13hrs. Any ideas as to how or why this may have happened, and how it can be prevented, would be wonderful. -Rich -- Richard West $14.95 Registrations mailto:rwest@wesmo.com Wesmo Computer Services .com .net .org .tv .cc http://www.wesmo.com Full Domain & Web Hosting .BIZ .INFO & MORE!!

[Dovecot] Outlook express confusion
by Andrew Hutchings 08 Apr '05

08 Apr '05

Hi, This may be a problem with my config file but I am finding that customers (and more importantly my boss) that are using outlook express when using test66/67 (upgraded from test60 + from address patch) are having message reappear after being fully deleted (not just marked) but are unreadable, sometimes blank headers appear too but again no message. Since it is affecting my boss he has told me to go back to test60 or lower, and won't let me find the problem.

[Dovecot] maildir quota management
by Wayne Lovely 08 Apr '05

08 Apr '05

Hi everyone, my name is Wayne Lovely and this is my first post. My company has a need for dovecot to decrement the portion of quota used. The used portion and hard limit will be stored in a central database. Initially I'll just hack in what we need as a proof of concept, but I would like to get some input into what people would really like, such that I can make a good contribution. regards, Wayne Lovely

[Dovecot] 1.0-test67
by Timo Sirainen 08 Apr '05

08 Apr '05

http://dovecot.org/test/ Hopefully better release than last one. Fixes several problems test66 had and also some older problems reported in this list. It also contains a pretty large mbox code cleanup, fixing several problems (especially related to X-IMAP/X-IMAPbase headers) and making it a bit faster. Maybe I'll backport it to 1.0-stable too when it looks like it's stable.. BTW. mbox code is slower than necessary when updating message flags and mbox_lazy_writes=yes, because it reads message headers for each message whose flag is to be changed (in index). Should fix that one soon too..

Re: [Dovecot] Delimiter of mailbox changes in response to STATUS command...
by Lawrence Katz 08 Apr '05

08 Apr '05

Hi Chris - Thank you for the reply. > I can't reproduce this in our setup in either 1.0-stable or > 1.0-test66. What's your namespace definition and MAIL= environment? > What does > > 1 LIST "Misc/" "*" > > give you? The LIST command returns what I expect to see (for readability): 2 list "Misc/" "*" * LIST (\HasNoChildren) "/" "Misc/Spam" > Can you 1 SELECT "Misc/Spam" OK? I can select that mailbox as well as others without a problem. Here's what NAMESPACE returns: 3 NAMESPACE * NAMESPACE (("" "/")) NIL NIL My namespace definition in dovecot.conf is as follows: namespace private { separator = / # prefix = # location = inbox = yes # hidden = yes } I didn't have default_mail_env set to anything, but I just tried the following without a change in the STATUS command's behavior: default_mail_env = maildir:/home/%u/Maildir Is there any other information that might help? Thanks, Lawrence

[Dovecot] Linux, Maildir over NFS, Locking problems
by Terrence Martin 08 Apr '05

08 Apr '05

Hi, I am having problems with file locks with my NFS mounted Maildir setup. NFS Client/IMAP Server is RHEL3 clone whitebox and NFS server is a Fedora Core 2 system. Both are running lockd as far as I can tell. dovecot is installed with Dag's latest dovecot RPMs for RHEL3. Time is synced between the two systems. Here is the pertinent log file entry dovecot: Dovecot starting up Apr 7 11:17:42 sentry imap(tmartin): /home/tmartin/Maildir/.subscriptions failed with subscription file file_wait_lock(): No locks available Now what I can find in nfs.txt is that I need to use fnctl is this ".customflags and .subscriptions files require fcntl() locking currently. Many NFS servers don't support it, at least without a separate lockd daemon. These will be fixed later to be NFS-safe by default." My question is am I using fcntl? The only reference I can find in the config refers to mbox formats, but I am using maildir. Setting the one reference to fcntl does not seem to have any effect. Is there a configuration setting to tell the server to use fcntl locks or a way to tell if it is trying to use fcntl locks? Thanks for any tips, Terrence

[Dovecot] MySQL-Auth Problem

Hi, i would use Dovecot-test66 with MySQL-Auth for virtual users. MySQLd version: 4.1.10a I compliled dovecot with: CPPFLAGS=-I/usr/include/mysql LDFLAGS=-L/usr/lib ./configure --prefix=/usr --sysconfdir=/etc/dovecot --without-passwd --without-shadow --without-pam --without-checkpassword --without-bsdauth --without-vpopmail --with-mysql --with-ssl=openssl --with-storages=maildir --with-moduledir=/etc/dovecot/modules but if i start Dovecot i get: Apr 3 12:44:28 l2 dovecot: auth-worker(default): mysql: Connect failed to 127.0.0.1 (mail): Benutzer 'mail'@'localhost' hat keine Zugriffsberechtigung (verwendetes Passwort: Ja) - waiting for 75 seconds before retry but password and user are correct and worked with dovecot 0.99.14 cu Felix

[Dovecot] 1.0-test66
by Timo Sirainen 08 Apr '05

08 Apr '05

http://dovecot.org/test/ I've still lots of mails in my INBOX and in this list that I should be looking into.. But here's a release that fixes at least some things. Maybe I'll make another one tomorrow.. Most importantly keyword code was changed a lot. It's now faster and less buggy. The keywords are also finally written into mbox, and keyword changes in the mbox are picked up. So upgrading from Dovecot 0.99.x or UW-IMAP (or reverting back to them) doesn't anymore lose the keywords. Maildir still needs 0.99.x-compatible customflags-file and storing the keywords as a..z flags in maildir filename. Hopefully I'll get that done soon, and then we should be nearing 1.0-alpha1 release :) The new keyword code hasn't been tested much, so this might be less stable than earlier versions. - Renamed oe6-fetch-no-newmail workaround to delay-newmail and changed it to work more like the name says: only newmail notifications are skipped and not only for FETCH command. - LDAP crashfixes - Changed FETCH to return smaller items first. Should fix all kmail and Thunderbird problems. Removed tb-negative-fetch workaround as it shouldn't be needed anymore. - Cache file was breaking constantly with test65 - Blocking passdb fixes and proper RPA realm support patches from Andrey - in-memory indexes should be working again if someone wants to use them for some reason (:INDEX=MEMORY) - gzipped mbox plugin http://dovecot.org/patches/1.0/zlib-plugin.tar.gz - SORT crashfix - Some mbox rewriting fixes (should fix some asserts) - etc.

[Dovecot] Question about "reply from worker without password scheme"
by Zoong PHAM 08 Apr '05

[Dovecot] imap segfault in mail-cache.c
by Todd Burroughs 08 Apr '05

08 Apr '05

Found an imap crash. I'm using the CVS copy from March 23. This is running under Linux, kernel 2.6.11.something. We use mbox over NFS, everything is on the NFS server. There is currently only one dovecot server accessing the mailbox. Here's the log messages: dovecot: Apr 05 13:11:20 Error: 27911 IMAP(support): UIDVALIDITY changed (1112720886 -> 1112721068) in mbox file /mailhome/new/m/support/mbox dovecot: Apr 05 13:11:20 Error: 27911 IMAP(support): mbox sync: UID inserted in the middle of mailbox /mailhome/new/m/support/mbox (316790 > 316789) dovecot: Apr 05 13:11:20 Error: 27911 IMAP(support): Corrupted index cache file /mailhome/new/m/support/.imap/INBOX/dovecot.index.cache: indexid changed dovecot: Apr 05 13:11:20 Error: child 27911 (imap) killed with signal 11 Here's a backtrace.

[Dovecot] Archiving Dovecot format maildir
by Leslie Viljoen 08 Apr '05

08 Apr '05

Hi! It seems that the Maildir format used by Dovecot is a standard, right? Has anyone written something to archive mail in Dovecot format maildirs? I have a script that seems to be for Cyrus IMAP but it doesn't seem to work. I'll write a Perl program if there is nothing available but I am concerned about dovecot's index files - do I need to do anything to get dovecot to rebuild them? Leslie Viljoen

[Dovecot] headers don't match message
by Kevin 08 Apr '05

08 Apr '05

the other day i moved all mail functions to a different machine. i copied over my existing maildir's and installed dovecot-stable-20050405. once i had everything moved and dovecot running i checked my mail via imap. all the messages appeared however when i try to read a message the message body doesn't match the header info that's showed in the message list. is this an index problem? or did i corrupt my maildir when i moved it over to another host?

[Dovecot] public or shared folders
by Richard Stegman 08 Apr '05

08 Apr '05

Hello I would like to setup a public namespace with folders under it that are accessiable by certain users. Something like this: Projects---- | |-----03060 | |-----04579 Users should be able to move emails from their inbox to the shared folders, and all user can see the moved email. Here is what I have done so far: 1. I installed dovecot-1.0-0 4 stable20050221.rhf3.at.i386.rpm to a Fedora core 3 machine with Postfix and procmail. 2. Tested mail server - both pop and imap work. 3. Modified dovecot conf. file with the following entry: namespace private { separator = / prefix = inbox = yes hidden = no } namespace public { separator = . prefix = Projects. location = maildir:/var/mail/Projects inbox = no hidden = no } 4. Restart dovecot. Test - imap and pop work. 5. Create group imapu. Add email users to group imapu 6. Create (as root) /var/mail/Projects. Change group to imapu. Change mode 770 7. Touch file dovecot-shared to /var/mail/Projects. Change group to imapu. Change mode 770 8. Make directory /var/mail/Projects/.03060. Change group to imapu. Change mode 770 9. Touch file dovecot-shared to /var/mail/Projects/.03060. Change group to imapu. Change mode to 770 10. Restart dovecot. I start up thunderbird and the Project namespace shows up. I then subscribe to 03060 and get this error: The current command did not succeed. The mail server responded: Error in IMAP command UID: Invalid BODY[..] parameter: Missing '>' <10240.-1357>'. I click ok and I can move email from the inbox to 03060. The mail shows up in 03060. No other user can then subscribe to 03060. What am I doing wrong? Thanks Rick

[Dovecot] pam problems
by Matthieu Imbert 07 Apr '05

07 Apr '05

Hi, i'm quite new to dovecot. i built it from the stable-1.0 sources. i have the following error messages in syslog when trying to launch dovecot: dovecot: Dovecot v1.0-stable starting up dovecot: auth(default): Unknown passdb type 'pam' dovecot: Auth process died too early - shutting down dovecot: child 373 (auth) returned error 89 i googled a bit, and found some posts on this mailing list describing the same problem, and the answer is that pam support is not compiled in. So i tried to ensure pam support would be compiled: i made sure that i have the proper libs. I work on debian so i did: apt-get install libpam-runtime libpam-modules apt-show-version tells me the version numbers installed: ... libpam-modules/testing uptodate 0.76-22 libpam0g/testing uptodate 0.76-22 libpam-runtime/testing uptodate 0.76-22 libpam-ldap/stable uptodate 140-1 ... my configure line is as follows: ./configure --sysconfdir=/etc --localstatedir=/var --with-ssl=openssl --with-pam when running configure, the only line related to pam is the following: checking for pam_start in -lpam... no and at the end of the configure script i get the following summary: Building with user database modules : static passwd passwd-file checkpassword (modules) Building with password lookup modules : passwd passwd-file shadow checkpassword (modules) So it seems that pam support is not built in. What is the lib i am missing ? Any help appreciated, thanks -- \|||/ (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> -----------------------------------------------------

Re: [Dovecot] Dovecot 1.0 POP3 login but no mail
by david＠stpenable.com 06 Apr '05

I followed Geralds' instructions and dovecot returns "0 0" to stat cmd and "0 messages:" to list. So it thinks there are zero when there are over 40 in "%h/.maildir". I had not changed my config file before reboot so how can this happen? It worked prior to reboot and not after. I get no maillog errors, what next? Thx.
