[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?
by Dan Stromberg 27 Apr '05

27 Apr '05

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)?

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

[Dovecot] Limiting IP range access
by Luigi Rosa 25 Apr '05

First of all, MANY compliments for this fantastic software. Now the question: is it possibile to limit the access to dovecot (or a single service) to a specified range of IPs? Basically, I am thinking about an IP-based ACL. Thankyou in advance. Ciao, luigi -- A beer delayed is a beer denied.

[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

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

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.

[Dovecot] 1.0 release
by Patrick Avery 21 Apr '05

21 Apr '05

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] dovecot-sasl license
by Marcus Rueckert 19 Apr '05

19 Apr '05

hi, i talked to timo about re-licensing the sasl part of dovecot under a more liberal license (bsd/lgpl e.g.). it would allow the integration of it in bsd base systems. another reason i would be interested is adding sasl support to svnserve [1]. so here is my question: what is your oppinion about this issue? any objections from contributors? darix [1] http://subversion.tigris.org/ -- irssi - the client of the smart and beautiful people http://www.irssi.de/

[Dovecot] attr_names in test67

Hello, I'm wondering if the following situation is valid (though I think it isn't since I still cannot authenticate with ldap pass/userdb on test67 running on FreeBSD-5.3).

[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] Multiple auth mechinisms

From the WIki features page, ( http://wiki.dovecot.org/moin.cgi/CoreFeatures ) it's not clear to me if the dovecot-stable release supports multiple authentications mechanisms (like in 1.0-testxx). I need both virtual domains and system users. Can I use the stable release for this? Thanks, --Micha

[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.

[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

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.

[Dovecot] Delimiter of mailbox changes in response to STATUS command...
by Lawrence Katz 06 Apr '05

06 Apr '05

Hi - I've been using Hastymail with my Dovecot server for awhile now. However, I have noticed that at some point Hastymail stopped showing the number of unseen messages in its folder drop down list, it just shows 0 for the folders that I have it checking for unseen messages. I'm not sure when it broke, but I think it's when I went to one of the testing builds several months ago. I just upgraded to Hastymail 1.3 and Dovecot testing66 today just to see if the issue would go away and it hasn't. So I did some digging and I think I found the cause of the issue... If I send a STATUS command, like the one shown below, Dovecot changes the mailbox delimiter in the result from a "/" to a "."... 2 STATUS "Misc/Spam" (UNSEEN) * STATUS "Misc.Spam" (UNSEEN 3) 2 OK Status completed. I was able to work around this in Hastymail by substituting a "/" for a "." when the result comes back, but it's not that elegant. Any thoughts on why this might be happening in Dovecot? Is it a configuration issue on my part, or a bug? The private namespace in my dovecot.conf has the following: separator = / Thanks, Lawrence

[Dovecot] Dovecot 1.0 POP3 login but no mail
by David Wynter 06 Apr '05

06 Apr '05

Dovecot is installed on the hosted FC1 server I have, it was working fine until yesterday when they had to bounce the server. I can login fine from Outlook or connect telnet <hostname> 110. But even though I can see sendmail has received mail into my %h/.maildir (via webmail's user mail facility) when I log into dovecot via Outlook it does not retrieve any of it. I tried from W2K "telnet <hostname> 110", it connects "+OK dovecot ready.", then I typed "LOGIN <username> <password>" and i get "-ERR Unknown command.". However with Outlook it logs in fine I see in maillog the result, no other errors in maillog. Cannot see what is wrong. Here are the important bits of my dovecot.conf, everything else is std. i.e. commented out protocols = pop3 login = imap login = pop3 default_mail_env = maildir:%h/.maildir client_workarounds = outlook-idle mbox_locks = fcntl auth = default auth_userdb = passwd auth_passdb = pam auth_user = root auth_verbose = yes Ideas on where to look next?

[Dovecot] FETCH order fix backport to stable from test66
by Chris Wakelin 05 Apr '05

05 Apr '05

I've had a go at back-porting Timo's recent fixes to the IMAP fetch command from 1.0-test66 to 1.0-stable. This seems to fix the problem with kmail, and Thunderbird seems to work fine without its RFC822.SIZE fix. It's a bit big for the body of this message, so it's attached. The bit I'm most concerned about in my port is whether I got the buffer_insert call right (back-ported from an array_insert call) in imap-fetch.c :- @@ -119,8 +129,14 @@ memset(&h, 0, sizeof(h)); h.handler = handler; h.context = context; + h.buffered = buffered; - buffer_append(ctx->handlers, &h, sizeof(h)); + if (!buffered) + buffer_append(ctx->handlers, &h, sizeof(h)); + else { + buffer_insert(ctx->handlers, ctx->buffered_handlers_count * size of(h), &h, sizeof(h)); + ctx->buffered_handlers_count++; + } } 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] ldap auth with test66
by Thomas Hummel 04 Apr '05

04 Apr '05

Hello, The installation of 1.0-test66 (still on FreeBSD 5.3-RELEASE-p1 with openldap-2.1.27) solved the SIGSEV problem I posted here on March 30 but I still cannot authenticate correctly with ldap. logs report "ldap(dovetest,127.0.0.1): No password in reply" and my client gets a "NO Temporary authentication failure." Obviously the attr_names array of the passdb_ldap_connection struct is valid until the preinit function but has been corrupted when we're at the passdb_init function. For instance, here's what I get in the log file for the 'fields' value : --- dovecot: Apr 04 11:43:19 Info: Dovecot v1.0-test66 starting up dovecot: Apr 04 11:44:58 Info: auth(default): client in: AUTH 1 PLAIN service=IMAP secured lip=127.0.0.1 rip=127.0.0.1 resp=AGRvdmV0ZXN0AHBhc3M = dovecot: Apr 04 11:44:58 Info: auth(default): ldap(dovetest,127.0.0.1): base=ou= personnes, dc=pasteur, dc=fr scope=subtree filter=(&(objectClass=posixAccount)(u id=dovetest)) fields=0^S^<^S^d^S^°^S^ð^S^^T^T^Ð^T^Ø^T^^C -- Beside, I could notice, by adding some logging info, that the attr_names seem to hold the USER attrs instead of the PASS attrs. I'm trying now to investigate further through gdb (I added a sleep in the main of dovecot-auth to be able to attach the running process in gdb) but without success for now. Do you have any clue of where I should look ? -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] Nested folders
by Michael Irons 03 Apr '05

03 Apr '05

I would like to have nested folders that users could create from their MUA. The problem is that I cannot create sub folders either through the MUA or by hand on the server side. I can make folders that are not the subfolder of anything. I have an Inbox, Mailing Lists, Spam, Trash, etc. But I cannot create subfolders of these. For example, I would like a subfolder under Mailing Lists for each Mailing list that I have subscribed. I am using Postfix that delivers directly to procmail which puts mails into Maildir style mail boxes in each users home directory. I am using the dovecot-0.99.13-4.FC2 rpm if that helps. I am sure that there would be some information about this somewhere, but I haven't found it in the mailing lists or googling around. The only information I have been able to find is that dovecot reportedly supports this. Thanks, Mike

[Dovecot] We couldn't drop root group privileges

Hi, I just installed dovecot. The installation went well and i configured dovecot to user ~/Maildir. When I tested imap via telnet the login work, but right after that the connection is cutted: Trying 192.168.0.14... Connected to op. Escape character is '^]'. * OK dovecot ready. . login jerik password . OK Logged in. Connection closed by foreign host. And the log says: dovecot: Apr 02 19:37:18 Info: Dovecot starting up imap-login: Apr 02 19:38:03 Info: Login: jerik [192.168.0.23] imap(jerik): Apr 02 19:38:03 Fatal: We couldn't drop root group privileges dovecot: Apr 02 19:38:04 Error: child 15194 (imap) returned error 89 So the problem is that dovecot "could't drop root group".

I am combining a MySQL database of virtual host accounts with the system password database of local machine accounts. Both work correctly when enabled on their own, but when enabled together only the one listed first in the "auth default" section of dovecot.conf works - the other logs the following error (line 5 below): Mar 29 21:56:50 rivendell dovecot: Dovecot v1.0-test65 starting up Mar 29 21:56:51 rivendell dovecot: auth(default): mysql: Connected to 127.0.0.1 (maildomains) Mar 29 21:56:51 rivendell dovecot: auth-worker(default): mysql: Connected to 127 .0.0.1 (maildomains) Mar 29 21:57:05 rivendell dovecot: auth-worker(default): BUG: PASSV had invalid passdb num Mar 29 21:57:38 rivendell dovecot: Killed with signal 2 To the client, dovecot locks up when a LOGIN command is issued for a user which can't be authenticated using the first method available (in my case, passwd). So for me, /etc/passwd users can still log in ok, but dovecot will lock up whenever a login with any other username is attempted.

Default namespace is simply done by having a # namespace with empty prefix. #namespace private { # Hierarchy separator to use. You should use the same separator for all # namespaces or some clients get confused. '/' is usually a good one. #separator = / # Prefix required to access this namespace. This needs to be different for # all namespaces. For example "Public/". #prefix = # Physical location of the mailbox.

[Dovecot] Trouble with basic Dovecot setup
by paul wisehart 03 Apr '05

03 Apr '05

Hi, I have compiled dovecot-1.0_stable. (http://dovecot.org/nightly/stable/dovecot-stable-20050328.tar.gz) I have it set to "userdb = passwd" & "passdb = passwd" I have a user "wise" with an maildir type mailbox at ~/Mail The actual maildirs are all subfolders with the INBOX "inbox" being one of them. I also have setup the ssl certificates with the script from the source doc directory. I start dovecot, and try to login from a seperate machine running thunderbird. I tell it to use ssl ( 993 ).

[Dovecot] QUOTA support timeframe? (also -- folders in folders?)
by Gerald V. Livingston II 03 Apr '05

03 Apr '05

I see it's been in the wishlist a while. Any possible timeframe for getting it working, or maybe a patch (or is it too big a change) to support it? I'm building a new server to move an existing userbase to. So far I have working: Postfix (with Maildir quota patches that work fine) Amavis-new with ClamAV scanning for viruses (will add SpamAssassin soon) SquirrelMail IMP (Horde) (Yes, 2 webmails to allow customers a choice of interface) Right now my test accounts have quotas, but they have no way to see where they stand without IMAP++ QUOTA support. Also, a question. Does Dovecot support folders within folders other than INBOX? I hadn't even thought about that question until I tried to create a test folder from within Squirrelmail and checked the "Let this folder contain subfolders" box and the creation failed ---- nevermind, that must be a Squirrelmail oddity. I created another folder inside the test folder and it worked OK -- just have to NOT check that box. Thanks all, Gerald

Hi, I know that's how Demon do it, but surely it's not the only way of doing it.

Dovecot does not do this. And I don't see a need for that. Configure your MTA to put the envelope data into the mail header (e.g. Return-path and Envelope-to). I used this several times for multidrop-mailboxes (which also seems to be the main use of SDPS).

[Dovecot] virtual user question
by Steve Hoffman 03 Apr '05

03 Apr '05

I'm sorry if this has been asked already, but I'm new to the list and to dovecot. I'm trying to add imap to our existing setup where we host many virtual domains and would like to use dovecot to do it as I find it's one of the most configurable I've seen so far. The problem is that our virtual users passwd files are kept in seperate directories so /etc/virtual/%d/passwd, but I can't use the variable substitution in the dovecot.conf file as it results in a load error because it won't translate the %d. I'm using the latest development release, test65. I read in the config file that you can use many passdb's but do I have to put them all in there or is there a way to use some sort of substitution? The other issue I'm having is when I try to test the connection (with a hard coded path to passwd) it fails auth if I pass the username "user(a)domain.com" but passes if I pass just "user". Any help or places you can point me for these issues? Thanks, Steve

[Dovecot] new to dovecot, dealing with MH foders
by jerry scharf 03 Apr '05

03 Apr '05

Hello, I'm sorry if this is a repeat, a few choice searches into google didn't help and I found no search for the archives. I can no longer put of moving away from UW-IMAP. Dovecot certainly seems to be the right choice, but I am having problems getting it to do what I need it to for all my mail. The machine is running the dist version, 0.99.12. I have a system mailbox and a large MH mail tree (~25K messages.) I saw that dovecot didn't support mh trees like UW did. It looked like maildir would be a good common target. So I found a script that would convert the mbox to maildir and have adjusted postfix, and that all works fine. Then I found mh2maildir, and ran it over my entire mh tree. Then I tried just for a test copying one of the small top level directories under ~/Maildir, but my MUA (mulberry) doesn't see it. So how do I get dovecot to see things other than the inbox in maildir format? How can I easily test to see if it's dovecot's problem or the MUA? thanks for any help, jerry Jerry Scharf laguna way consulting

[Dovecot] dovecot-1.0-test65 + mysql build problem (sha1_result)

[Dovecot] FC2 POP3/SMTP Configuration
by Linux Stuff 02 Apr '05

02 Apr '05

OK, let me try this again. . . . I'm a newbie to dovecot and a little bit less of a newbie to linux. I am in the process of moving my server from RH9 to FC2. The only obstacle remaining is my email. I run dovecot (v0.99.14) POP3 and sendmail (8.12.11-4.6) with Mozilla (1.4.2 and others), Thunderbird (1.0.2) and Netscape (7.1 on PC's, etc) mail clients - mostly PC's (W2K, WXP). They all can read their mail but none of the users can send any mail. I have also tested with Outlook and it works!? Ximian Evolution (1.4.6) also works!??? Depending on the state of the dovecot.conf file, I get the following: Mar 28 16:04:14 corvette sendmail[5810]: unable to open Berkeley db /etc/sasldb2: Invalid argument Mar 28 16:04:14 corvette sendmail[5810]: unable to open Berkeley db /etc/sasldb2: Invalid argument Mar 28 16:04:14 corvette sendmail[5810]: no secret in database Why do Outlook and Ximian work and the others do not?

[Dovecot] LDA Wishlist idea

02 Apr '05

Hi all, Sorry if this is out of place, but I've seen people suggesting future functionality for Dovecot on here before. TBH I'm not completely sure if this would be possible in a LDA. Demon (an ISP) have extensions to POP3 they call "SDPS" - there's basically an extra command that can be called for an email and it gives the envelope rcpt and from addresses. I was wondering if there was any chance of future versions of Dovecot allowing something similar?

Re: [Dovecot] [ #14832]: Capital letters in POP3 logins
by Gerald V. Livingston II 01 Apr '05

I just tested and IMAP doesn't ignore case either. Remove the UPPER CASE maildir created by your POP3 login then do the same thing with an IMAP client. Set up the IMAP client to use an UPPER CASE username and when you log-in/refresh folders it creates the new UPPERCASE empty Maildir all over again. Crap, between this and the missing QUOTA feature I guess I'm gonna have to rip out Dovecot and use Courier. I really wanted to use Dovecot for it's speed with the indexing. What I don't understand is -- all usernames in my test database are stored in lower case -- shouldn't it simply fail to match and cause the login to fail? Can anyone point out how to force the match to be case sensitive? I'll investigate and get back to the list. It would be "nicer" though if Dovecot converted all username input to lower case before authenticating to maintain uniqueness of email addresses.

[Dovecot] test65 killed by SIGSEV
by Thomas Hummel 31 Mar '05

31 Mar '05

Hi, I had successfully set up dovecot-1.0-test62 + ldap pass/user db, but now I'm encoutering a SIGSEV problem with a similar set up of a brand new dovecot-1.0-test65 installation. The auth process is killed by a SIGSEV as reported in the error log file : dovecot: Mar 30 17:06:59 Error: child 28291 (auth) killed with signal 11 To be precise, the problem occurs in the "ldap_lookup_pass" function (auth/passdb-ldap.c) just before loging the ldap request parameters (auth_request_log_debug) and to actually perform the search (db_ldap_search). The signal occurs on the call of t_strarray_join(attr_names, ",") What I'm observing is that the "attr_names" array of the "passdb_ldap_conn" ldap connection doesn't seem to hold the right attributes : while in the test62 version it holded 'uid' and 'userPassword', it holds now 'uid' and 'homeDirectory'. As a matter of fact, the content of this array seem to change between the "preinit" and "init" passdb function and I'm not quite sure this is legal. So my client (actually just a test through telnet) gets a 'NO Temporary authentication failure'. Here's a gdb backtrace of the process : ------- Program received signal SIGSEGV, Segmentation fault. 0x08065bf6 in t_strarray_join (arr=0x807aa20, separator=0x8067b1a ",") at strfuncs.c:571 571 len = strlen(*arr); (gdb) bt full #0 0x08065bf6 in t_strarray_join (arr=0x807aa20, separator=0x8067b1a ",") at strfuncs.c:571 alloc_len = 8 sep_len = 1 len = 9 pos = 39 needed_space = 0 str = 0x806e488 "uid,homeDirectory,,,uidNumber,gidNumber" #1 0x080578a1 in ldap_lookup_pass (auth_request=0x8077a10, ldap_request=0x8077ab0) at passdb-ldap.c:181 conn = (struct ldap_connection *) 0x807a810 vars = (const struct var_expand_table *) 0x807a9a0 attr_names = (const char **) 0x807aa08 filter = 0x806e268 "(&(objectClass=posixAccount)(uid=dovetest))" base = 0x806e468 "ou=personnes, dc=pasteur, dc=fr" str = (string_t *) 0x806e268 #2 0x08050947 in auth_request_verify_plain (request=0x8077a10, password=0x806e198 "pass", callback=0x8054790 <verify_callback>) at auth-request.c:261 passdb = (struct passdb_module *) 0x806b9e0 result = -1077941592 cache_key = 0x646975 <Error reading address 0x646975: Bad address> __PRETTY_FUNCTION__ = "auth_request_verify_plain" ---Type <return> to continue, or q <return> to quit--- #3 0x0805486e in mech_plain_auth_continue (request=0x8077a10, data=0xffffffff <Error reading address 0xffffffff: Bad address>, data_size=6580597) at mech-plain.c:62 authenid = 0x806e181 "dovetest" error = 0xbfbfeaf8 "(ë¿¿²ø\004\b\020@\b\b\034\020\b\b(ë¿¿dø\004\b\002" pass = 0x806e198 "pass" i = 0 count = 2 #4 0x08051a80 in auth_request_handler_auth_begin (handler=0x8084010, args=0x808101c "1\tPLAIN\tservice=IMAP\tsecured\tlip=127.0.0.1\trip=127.0.0.1\tresp=AGRvdmV0ZXN0AHBhc3M=") at auth-request-handler.c:327 len = 20 mech = (struct mech_module *) 0x0 request = (struct auth_request *) 0x8077a10 list = (const char * const *) 0x806e114 name = 0x806e130 "resp" arg = 0x806e160 "\200á\006\b\016" initial_resp = 0x806e0de "AGRvdmV0ZXN0AHBhc3M=" initial_resp_data = (const void *) 0x646975 initial_resp_len = 0 id = 1 buf = (buffer_t *) 0x806e160 valid_client_cert = 0 ---Type <return> to continue, or q <return> to quit--- #5 0x0804f8b2 in auth_client_input (context=0x80785c0) at auth-client-connection.c:144 conn = (struct auth_client_connection *) 0x80785c0 line = 0x8081017 "AUTH\t1\tPLAIN\tservice=IMAP\tsecured\tlip=127.0.0.1\trip=127.0.0.1\tresp=AGRvdmV0ZXN0AHBhc3M=" #6 0x0805f8dc in io_loop_handler_run (ioloop=0x8078000) at ioloop-poll.c:184 data = (struct ioloop_handler_data *) 0x806d080 pollfd = (struct pollfd *) 0x2 tv = {tv_sec = 1, tv_usec = 999555} io = (struct io *) 0x806d5c0 t_id = 2 msecs = 0 ret = 0 call = 1 #7 0x0805f319 in io_loop_run (ioloop=0x8078000) at ioloop.c:218 No locals. #8 0x080541dd in main (argc=1, argv=0x1) at main.c:311 foreground = 0 (gdb) ------- Thanks -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] Pine and prefix - LIST command bug?
by Chris Wakelin 31 Mar '05

31 Mar '05

I've been having problems with Pine 4.62 talking to Dovecot 1.0 stable. It's fine when the folder collection path is empty, but if I have "~/mail/" or "mail/" it gives access errors (I'm using the "~/mail/", "mail/" etc. hidden namespaces for backwards compatability). It seems to me that Dovecot is not replying correctly to a "LIST" command with empty mailbox name: - Dovecot: xyz LIST "" "" * LIST (\NoSelect) "/" "" xyz LIST "~/mail/" "" * LIST (\NoSelect) "/" "" xyz LIST "mail/" "" * LIST (\NoSelect) "/" "" UW-IMAP; xyz LIST "" "" * LIST (\NoSelect) "/" "" xyz LIST "~/mail/" "" * LIST (\NoSelect) "/" ~/ xyz LIST "mail/" "" * LIST (\NoSelect) "/" mail/ RFC 2060 says: An empty ("" string) mailbox name argument is a special request to return the hierarchy delimiter and the root name of the name given in the reference. The value returned as the root MAY be null if the reference is non-rooted or is null. In all cases, the hierarchy delimiter is returned. This permits a client to get the hierarchy delimiter even when no mailboxes by that name currently exist. Mind you, it looks like at least our UW-IMAP also gets it wrong for "~/mail/". Of course, I may be misunderstanding something!

support(a)majordomo.ru wrote: > Can I solve this problem or it is virtually "bug" of dovecot? No bug, just the "garbage in, garbage out" principle. Mysql's string matches are case-insensisitive by default, so when dovecot asks mysql for the user information of UsEr1, it will get the information of user1 and therefore assumes that UsEr1 is a valid login. It's not dovecot's fault. If you want the match case-insensitive (so UsEr1 will be rejected), add the BINARY attribute to the userid field or change your query to '... WHERE BINARY userid = "%u"' in password_query and user_query. If you want to allow logins as UsEr1 (and let him access user1's mail), you have to change your dovecot.conf, I think. Use %h instead of %u there, and let user_query return the home directory with something like 'SELECT CONCAT('/var/spool/vmail/',LOWER(userid)) AS home, ...'.

[Dovecot] [ #14832]: Capital letters in POP3 logins
by support＠majordomo.ru 30 Mar '05

Hello all! I'm newbie here :) Using dovecot (version 1.0-test59, with mysql-auth) I saw strange problem: after authentication by POP3 in case that username given has capital letters, for example SupportTeam(a)majordomo.ru, dovecot creates new maildir 'SupportTeam' for this username instead reading mails from existing maildir 'supportteam'. Then dovecot scans created maildir 'SupportTeam' and returns 0 messages (sure:). IMAP4 works fine in the same time. Can I solve this problem or it is virtually "bug" of dovecot? Thanks in advance!

[Dovecot] Chrooting dovecot.
by BSD Mail 30 Mar '05

30 Mar '05

Greetings, I have installed Dovecot under FreeBSD 5_3 It is pretty impressive. I got SSL working with no problem for both imap and pop3. Besides that I do still want to chroot Dovecot. I noticed that there are some options in the dovecot.conf that are intended for this. Unfortunately online resources on how to do that can't be found on google. Although I'm running the server as user dovecot. I still do have this: dovecot pop3-login 491 1 tcp4 10.0.1.4:995 *:* dovecot pop3-login 490 1 tcp4 10.0.1.4:995 *:* dovecot pop3-login 489 1 tcp4 10.0.1.4:995 *:* dovecot imap-login 488 1 tcp4 10.0.1.4:993 *:* dovecot imap-login 487 1 tcp4 10.0.1.4:993 *:* dovecot imap-login 486 1 tcp4 10.0.1.4:993 *:* root dovecot 481 5 tcp4 10.0.1.4:993 *:* root dovecot 481 6 tcp4 10.0.1.4:995 *:* Fine for the first six lines it's doing what it's doing. But the last two lines are running as root. That is why I want to chroot the server. I would like if anyone can point me to some howto or notes on how to do so. If there is none I will have to configure a jail just for this purpose. Thanks in advance. -- Regards,

I just tried the latest version from CVS and got this error: dovecot: Mar 29 18:11:33 Error: 27526 IMAP(todd.bluegenesis.com): Corrupted index cache file /mailhome/new/t/b/todd.bluegenesis.com/.imap/INBOX/dovecot.index.cache: Duplicated field in header: hdr.RESENT-TO dovecot: Mar 29 18:11:33 Error: 27526 IMAP(todd.bluegenesis.com): file index-mail-headers.c: line 68 (index_mail_parse_header_finish): assertion failed: (match[match_idx] != mail->header_match_value + 1) dovecot: Mar 29 18:11:34 Error: child 27526 (imap) killed with signal 6 I deleted the index files, didn't help.

[Dovecot] Compile Error in current CVS

Had a small error with the current CVS version. It was in deliver.c. Here's a fix. I'm assuming that adding NULL is correct ;-) dovecot.2005-03-29/src # diff deliver/deliver.c.orig deliver/deliver.c 86c86 < box = mailbox_open(storage, mailbox, MAILBOX_OPEN_FAST | --- > box = mailbox_open(storage, mailbox, NULL, MAILBOX_OPEN_FAST | Here's the symptoms: deliver.c: In function `save_mail': deliver.c:87: warning: passing arg 3 of `mailbox_open' makes pointer from integer without a cast deliver.c:87: error: too few arguments to function `mailbox_open' make[3]: *** [deliver.o] Error 1 make[3]: Leaving directory `/services/src/9.2/dovecot/dovecot.2005-03-29/src/deliver' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/services/src/9.2/dovecot/dovecot.2005-03-29/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/services/src/9.2/dovecot/dovecot.2005-03-29' make: *** [all] Error 2

[Dovecot] Checkin 1.37 of src/lib-storage/mail-storage.c
by Geo Carncross 29 Mar '05

29 Mar '05

Checkin 1.37 of src/lib-storage/mail-storage.c added a parameter to mailbox_open() but this broke building src/deliver/deliver.c as revision 1.2 doesn't use the new parameter. It looks like save_mail() of src/deliver/deliver.c calls mailbox_open() and it looks like it might work fine if it were to use a (struct istream *)0 as the third parameter (instead of the flags) -- but I don't use deliver [yet], so I don't have any adequate way to test this. -- Internet Connection High Quality Web Hosting http://www.internetconnection.net/

[Dovecot] mbox zlib compression plugin
by Timo Sirainen 29 Mar '05

29 Mar '05

Some people have been asking this forever, but because it wasn't possible to implement it as a plugin, I hadn't done it. Now, due to some API changes for other purposes, it was suddenly easy. So, if you want to try it, grab the latest CVS code / nightly CVS snapshot and http://dovecot.org/patches/1.0/zlib-plugin.tar.gz Compilation instructions inside zlib-plugin.c file. What it does is check if mbox name ends with ".gz", if so it opens it as read-only using zlib. If the file isn't actually zlib compressed, zlib seems to be able to still access it as a normal file (but it's still read-only). It should be possible to implement it for maildir files as well by hooking into mail_get_stream().

[Dovecot] FC2 POP Configurtion
by Linux Stuff 29 Mar '05

29 Mar '05

I'm a newbie to dovecot and a little bit less of a newbit to linux. I am in the process of moving my server from RH9 to FC2. The only obstacle remaining is my email. I run sendmail with netscape mail clients - mostly PC's. They all can read their mail but none of the users can send. Depending on the state of the dovecot.conf file, I get the following: Mar 28 16:04:14 corvette sendmail[5810]: unable to open Berkeley db /etc/sasldb2: Invalid argument Mar 28 16:04:14 corvette sendmail[5810]: unable to open Berkeley db /etc/sasldb2: Invalid argument Mar 28 16:04:14 corvette sendmail[5810]: no secret in database I know I must be missing something, probably trivial. Does someone have a simple, easy-to-read, config file for dovecot pop running with sendmail? Thanks

[Dovecot] Address with whitespace shows as ""@MISSING_DOMAIN
by Chris Wakelin 28 Mar '05

28 Mar '05

It seems that Dovecot gets confused when presented with a header like: From: someone(a)somewhere.org i.e. with leading whitespace and no "friendly name" This shows up as ""@MISSING_DOMAIN in clients, such as Pine, that believe what Dovecot tells them rather than parsing the headers themselves (e.g. Thunderbird). Here's a sample IMAP session: xyz FETCH 728 ENVELOPE * 728 FETCH (ENVELOPE ("Tue, 22 Mar 2005 10:10:50 +0100 (BST)" "Test" ((NIL NIL "" "MISSING_DOMAIN")) ((NIL NIL "c.d.wakelin" "reading.ac.uk")) ((NIL NIL "" "MISSING_DOMAIN")) ((NIL NIL "" "MISSING_DOMAIN")) NIL NIL NIL "<Pine.GSO.3.96.1010704101043.17798B-100000@suma3>")) xyz OK Fetch completed. Here's UW-IMAP on the same mailbox: . FETCH 729 ENVELOPE * 729 FETCH (ENVELOPE ("Tue, 22 Mar 2005 10:10:50 +0100 (BST)" "Test" ((NIL NIL "c.d.wakelin" "reading.ac.uk")) ((NIL NIL "c.d.wakelin" "reading.ac.uk")) ((NIL NIL "c.d.wakelin" "reading.ac.uk")) ((NIL NIL "c.d.wakelin" "reading.ac.uk")) NIL NIL NIL "<Pine.GSO.3.96.1010704101043.17798B-100000@suma3>")) . OK FETCH completed I'm not sure I read the RFC correctly, but it looks like whitespace is allowed (and if it wasn't, I'd expect our MTA, Exim to fix it on delivery). There's a particular member of one of the UK academic computing mailing lists who always seems to do this, but I'm not sure how common a problem it is!

[Dovecot] Troubleshooting help
by Paul Michael Reilly 28 Mar '05

28 Mar '05

Somehow, hopefully to be determined, I got my Thunderbird/dovecot Fedora Core 3 configuration into a real snit, such that I can no longer access my INBOX. When Thunderbird tries to get the INBOX content (or get new mail) it reports "The current command did not succeed. The mail server responded: Invalid messageset: -2147483648:*." Scouring logs and googling has come up empty. Now I'm flailing at trying to get to a state that this problem does not exist. I'd like to understand how this situation arose and how to deal with it better if it happens to any other users on my mail server. Thanks, -pmr

[Dovecot] cannot select
by juri vrljicak 28 Mar '05

28 Mar '05

hi everybody, Found many many answers in here but...not this one. My imap client displays all of the folders but not the inbox one (cannot select inbox). Paths in imap.passwd seem to be fine. using mbox format and error log says "fail with mbox file..is a directory" which i already know. do i have to create a file? and what about valid uids and gids, i had some trouble with that too. well defined and nevertheless dropped.

[Dovecot] test65 "deliver" LDA bug
by "Branko F. Gračnar" 28 Mar '05

28 Mar '05

Hello. I've tried to implement dovecot's deliver LDA to my home mailserver. I've run into troubles :) dovecot-deliver.conf: -- snip -- mail = maildir:%h/Maildir:INBOX=maildir:%h/Maildir mbox_read_locks = flock mbox_write_locks = flock -- snip -- when i run: deliver -d bfg < email.txt dovecot delivers message to ~/Maildir/maildir/new It acctually creates "maildir" folder inside real maildir folder. If i try to list messages via Outlook express mail client, OE reports entire folder list, but also lists one message "which no longer exists on server". If i remove ~/Maildir/maildir folder this message dissaperas from OE imap folder listing. Test scenario: 1. start dovecot 2. try to deliver message using "deliver" program (succeedes) 3. try to open INBOX via imap: Outlook Express: - reports INBOX message listing with one message, which "doesn't exist on server anymore" - the next delivery test with "deliver" LDA fails (lots of nanosleep() calls) Thunderbird: - reports that there are NO messages in INBOX - still can delivery messages with "deliver" LDA deliver strace output (search for EVIL CODE string): --- snip --- execve("/opt/dovecot/libexec/dovecot/deliver", ["/opt/dovecot/libexec/dovecot/deliver", "-d", "bfg"], [/* 42 vars

[Dovecot] Another imap crash...
by Todd Burroughs 26 Mar '05

26 Mar '05

The segfault problem that was happening seems to be fixed. I'm still getting some "(imap) killed with signal 6" errors. I just noticed that it did get one segfault. Unfortunately, I don't have a core file. I'll try to get one if this happens again. Here's the error messages, not sure if it will help. I'm using the CVS copy from March 24. dovecot: Mar 26 05:28:20 Error: 4282 IMAP(support): Corrupted index cache file /mailhome/new/s/support/.imap/INBOX/dovecot.index.cache: indexid changed dovecot: Mar 26 05:28:20 Error: 4282 IMAP(support): Corrupted transaction log file /mailhome/new/s/support/.imap/INBOX/dovecot.index.log: invalid indexid (1111832898 != 1111831599) dovecot: Mar 26 05:28:20 Error: 4282 IMAP(support): Corrupted index file /mailhome/new/s/support/.imap/INBOX/dovecot.index: Record UIDs are not ordered dovecot: Mar 26 05:28:20 Error: 4282 IMAP(support): Corrupted transaction log file /mailhome/new/s/support/.imap/INBOX/dovecot.index.log: invalid indexid (1111831599 != 0) dovecot: Mar 26 05:28:20 Error: 4282 IMAP(support): Corrupted index file /mailhome/new/s/support/.imap/INBOX/dovecot.index: Record UIDs are not ordered dovecot: Mar 26 05:28:20 Error: child 4282 (imap) killed with signal 11 Todd Burroughs

[Dovecot] quota issue POP3
by Obantec Support 26 Mar '05

26 Mar '05

Hi Just u/g to RH FC3 from RH8.0 which seemed to work fine with quotas. I have quotas for usernames set up as /home/domain/domainX/username/ for web space 50MB say 48MB used so 2MB free and /var/mail/spool/username for email. 100MB (60MB used so 40MB is available). /var/mail/username is symbolic linked via to spool/mail under /var dovecot seems to be using the quota for /home/.. and sees only 2MB so refuses to write file back. maillog is reporting (username and IP replaced). Mar 16 13:20:03 proteus2a pop3-login: Login: username [11.22.33.44] Mar 16 13:20:03 proteus2a pop3(username): Error rewriting mbox file /var/mail/username: Disk quota exceeded Mar 16 13:20:03 proteus2a pop3(username): write() failed with mbox file /var/mail/username: Disk quota exceeded i am assuming this is when pop3 login is trying to re-write file back when deleting emails.

[Dovecot] Postfix SMTP AUTH patch updated
by Timo Sirainen 25 Mar '05

25 Mar '05

There was a small protocol change in later 1.0-test releases which made the older patches not to work. Updated the patch for Postfix 2.1.5 and added patch for Postfix 2.2.1. I also tested that it works with Dovecot 1.0-stable releases. So, if you're interested: http://dovecot.org/patches/postfix/

[Dovecot] Segfault in imap process
by Todd Burroughs 24 Mar '05

24 Mar '05

We've been testing dovecot for a while and I noticed yesterday that imap crashes quite often. It seems to be about even with SIGABRT and SIGSEGV. This one was SIGSEGV. Our system is SuSE Linux 9.2, 2.6.11.5 kernel (also happened with an older 2.6 kernel). Dovecot version is 1.0-test64 and was compiled with: "./configure --prefix=/services/dovecot --disable-ipv6" It's using mbox over NFS and I've configured "mmap_disable = yes". The mailbox that it crashed on is one of our support mailboxes and it is pretty busy. In the last 1/2 hour, it received over 100 emails. I had a look at the code, but didn't notice anything obvious. Thanks for any help... Here's the log messages: dovecot: Mar 22 18:22:23 Error: 19697 IMAP(support): UIDVALIDITY changed (1111532787 -> 1111533642) in mbox file /mailhome/new/s/support/mbox dovecot: Mar 22 18:22:26 Error: child 19697 (imap) killed with signal 11 and a backtrace: mail201:/services/dovecot/var/log # gdb /services/dovecot/libexec/dovecot/imap imap.core.pid19697 GNU gdb 6.2.1 Copyright 2004 Free Software Foundation, Inc.

Fw: [Dovecot] Auto Create Folders
by Chris L. Franklin 24 Mar '05

24 Mar '05

>> the problem might be: what would your mta do if: >> 1. the user never logged in via imap okay, so then they would never get there mail ? I guess I don't see where your going with this problem. >> 2. therefor no folders were created by dovecot .... Ok ?? >> 3. it has to deliver a spam message to the spam folder. Your right the filter would put it into the spam folder, witch it would created if it's not found. And as a side note the "Spam" folder was just a example folder name. Really for are needs it would be a folder called "Meetings" >> "so you have to ensure the folder existance at the user creation level >> imho. thats the logical point to do exactly that. >> checking for folder existance everytime a user might access a service is >> stupid. it costs at least a stat() call per directory." Some how you missed the part.I'd like to make sure this use always has this folder. Aka if they delete it, I'd like it to be recreated. PS. In the end all's it comes down to is i was wounder if there was a way to have dovecot auto create a folder or a list of folders at login. OR really if there was a way to tell dovecot a list of folders a user COULD NOT delete (But could delete the folders in side). -- Chris L. Franklin --

I notice that when I have two clients connected and one of them reads a new message, the server sends a status update which contains the number of unseen messages, but doesn't specifically say which ones have changed. I think the solution to this problem, while not wasting bandwidth, is to issue a unilateral FETCH FLAGS response whenever a flag changes. There doesn't seem to be a way to get dovecot (I'm using 0.99.10) to do this. Can the 1.0-test versions do this? cya .sig

[Dovecot] Hide non-accessable folder from users
by Remy Zandwijk 22 Mar '05

22 Mar '05

Hi all, In our faculty, people keep asking about shared mail folders. With Dovecot up and running this should be no problem. I think we will have about 50 shared folders. I did take a look at the various solutions, but not all of them are useable. For example, I do not want users to create sub-folders in shared folders. This means the symlink option is unuseable. In my opinion, the easiest solution is creating a namespace and create the shared folders in the location of this namespace. Every shared folders gets his own UNIX group ID. Offcourse, this works great. The ony big disadvantage is that every users 'sees' all shared mailfolders, even if the user does not have the proper rights to access the folders. Is there a way to hide the non-accessable folders from users? Best regards, Remy Zandwijk

[Dovecot] strange email client problems
by Gabriel Granger 22 Mar '05

22 Mar '05

I've got some issues with dovecot, that I need to resolve, I only have about 20 users in the office, but the average disk space used by each user is anywhere from 1GB up to at the extreme end of the scale 7GB. I'm using the mailbox format. The server is a P4 2.8 with a 1GB of ram and run off 250GB SATA disks. most users have lots of structured folders going as deep as 6 levels. The problems I'm getting are odd the problems that I'm getting at the moment are "cannot copy mail to sent folder", but sends the message fine, this doesn't happen all the time but happens to everyone but me... I'm using OS X's Mail.app which seems to always work:) all my users are using W2K and either ThunderBird or Mozilla The other problem which I've been made aware of... The users get the "loading message" or "opening messages" and the egg timer goes round but never completes. I managed to clear the problem by getting the user to close their email client and then kill their IMAP processes on the server, when the user logs in again the client responds correctly. Is there something I'm doing wrong with the configuration of dovecot? would using MailDir help, I dont want to migrate from Mailbox unless this change will make things better, I understand their are benefits from using MailDir, but I dont know if I will continue to see the same problems if I migrate. Any help or advise would be great, I should add that everyone is connecting to the server over SSL Gabe

[Dovecot] Mixing mbox and maildir
by Tom Alsberg 21 Mar '05

21 Mar '05

Hi there. I understood that in Dovecot 1.0 it should be possible to mix the usage of mbox and maildir mailboxes. I just downloaded, built, and am testing dovecot-stable-20050304. I'm a bit confused as to the terms of namespaces (haven't read that part of the RFC yet), but this does not seem related. Anyway, when I try specifying: default_mail_env = ~/mail/:INBOX=/var/mail/%u On login I'm immediately disconnected, seeing something like: dovecot: IMAP(user): Failed to create storage with data: ~/mail:INBOX=/var/mail/user in the log file. This seems more like a bug to me (or maybe something in permissions I haven't noticed - but I've checked...) Any way, according to the documentation, it will detect whether ~/mail/ is mbox or maildir - but would that enable having both mbox and maildir in that directory? The goal is, to deploy Dovecot 1.0 at some time, while here there are users who have both maildir and mbox mailboxes (I.E. spool is mbox, ~/mbox is mbox, ~/mail contains some mbox mailboxes for small stuff that users want to be able to access even using /usr/bin/mail, and some larger maildir mailboxes (less critical, or high volume - e.g. mailing lists). How is that possible? Thanks, -- Tom P.S. Thanks again, Timo and rest of developers for this big piece of code - I maintain Dovecot 0.99 in another place and it's by far the most useful IMAP server yet. -- Tom Alsberg - hacker (being the best description fitting this space) Web page: http://www.cs.huji.ac.il/~alsbergt/ DISCLAIMER: The above message does not even necessarily represent what my fingers have typed on the keyboard, save anything further.

[Dovecot] Shared maildirs with symlinking
by Gauthier Vandemoortele 21 Mar '05

21 Mar '05

Hello, I try to set up a shared maildir with symbolink links, but it doesn't work. The main user, from which I would share a mailbox, creates a mailbox named "Commun" with thunderbird. I see on the file system from the server that a directory .Commun is created in his ~/Maildir/ and that the file ~/Maildir/.subscriptions has now such an entry. Right. In ~/Maildir/Commun the permissions are /cur 700 /new 700 /tmp 700 .customflags 600 .imap.index 600 .imap.index.data 600 .imap.index.log 600 .imap.index.tree 600 dovecot-uidlist 600 and as owner MainUser/users (I work on a slackware 10, all the users have by default the group users.) So, I change all the rights to 770 for directories and 660 for other files (I don't forget .Commun itself) Now the other user ; he creates also a folder named "Commun", so that such an entry exists in .subscriptions. As admin, I delete his folder ~/Maildir/.Commun, and create a symbolink link ~OtherUser/Maildir/.Commun pointing to ~MainUser/Maildir/.Commun Now MainUser moves a mail in his folder Commun, always with thunderbird ; OtherUser sees now a message in the "same" folder, but he can't read it. In fact, Thunderbird displays a little icon but without textuel information, like subject, or so. If OtherUser clicks on it, the mailer hangs indefinitly. It's logical, the file created in ~MainUser/Maildir/.Commun has 600 as permissions. On the other hand, OtherUser can move or create a file in his folder Commun, but MainUser does'nt see it, I suppose because his index is not updated. I had read in http://wiki.dovecot.org/SharedFolders that : It's important to have dovecot-shared file created in the shared maildir with the permissions and group ID you want to have access to the mailbox. Dovecot uses the same permissions and GID when it creates index files, dovecot-uidlist file, new mail files, etc. With my experience, it seems that Dovecot creates the file regardless of the permissions of the shared folder. Can someone say how to resolve that ? I use dovecot-0.99.11 Thanks in advance, -- Gauthier Vandemoortele <gauthier.vandemoortele(a)skynet.be> ...

[Dovecot] Loading messages
by Gabriel Granger 19 Mar '05

19 Mar '05

Thanks to all for pointing out the Thunderbird bug workaround, I've got another question Some of my users are complaining that when they select a message, the email client says "Loading Message" and either takes a long time to display a small message or does not display the message at all. Its odd becuase it seems that larger message on these users machines seem to open more quickly then the small 1Kb - 15Kb messages. Looking a little further on the messages that wont open they all seem to be very small in size. Is this a common issue? or something i need to tweak on the dovecot.conf or on the client side? Gabe

[Dovecot] problems with migration to Maildir
by F. Even 19 Mar '05

19 Mar '05

I'm attempting to use Maildir and mbox together until I can finish migrating all mailboxes and figure out issues I'm having with a couple other mailboxes. But, I want to officially start using Maildir as the primary msg. store. Now...when I configure Dovecot as follows, it creates new folders in the ~/mail folder, which is where my mboxes reside: #default_mail_env = #default_mail_env = mbox:~/mail/:INBOX=~/mbox #default_mail_env = mbox:~/:INBOX=~/mbox #default_mail_env = mbox:~/mail:INBOX=~/mbox default_mail_env = maildir:~/Maildir #namespace private { # separator = / # inbox = yes # prefix = # location = mbox:~/mail:INBOX=~/mbox #} #namespace private { # separator = / # prefix = "Maildir/" # location = maildir:~/Maildir #} namespace private { separator = / inbox = yes location = maildir:~/Maildir } namespace private { separator = / location = mbox:~/mail } I would like to have access to the mbox hierarchy, but I want all new folders by default created in ~/Maildir. How do I go about acheiving this? Thanks, Frank

[Dovecot] postfix + SMTP AUTH using DOVECOT AUTH DAEMON
by Ing. Alejandro Rodriguez 18 Mar '05

hi ppl I'm the new member of the list. Looking at recent messages look like there is a way to do SMTP AUTH in postfix using the Dovecot AUTH daemon. Currently my Dovecot installation auth again PAM (local users) and a simple shadow file (for virtual users, I plan to move to MYSQL later). I don't want to have different databases one for dovecot a one for SASL. Where I can found the POSTFIX patch, or better, some kind of helper daemon for Postfix. thx A

[Dovecot] Namespaces and subscriptions
by Chris Wakelin 17 Mar '05

17 Mar '05

I've got a problem with subscriptions in 1.0-stable when migrating from UW-IMAP. I've modified the SUBSCRIPTION_FILE_NAME entries as suggested in the Wiki http://wiki.dovecot.org/Migration and included the "~/mail/" etc. hidden namespaces. The .mailboxlist files contain entries like "~/mail/somefolder" and the clients have "~/mail/" set as a prefix. In UW-IMAP: xyz LSUB "" "*" * LSUB () "/" ~/mail/somefolder xyz LSUB "~/mail/" "*" * LSUB () "/" ~/mail/somefolder Now with Dovecot: xyz LSUB "" "*" * LSUB () "/" "~/mail/somefolder" xyz LSUB "~/mail/" "*" * LSUB () "/" "~/mail/~/mail/somefolder" In other words, Dovecot is prepending the namespace to the list of folders stored in .mailboxlist. This causes Thunderbird to show the folders as -~ - mail | somefolder which are accessible. Squirrelmail gets completely confused and tries to display "~/mail/~/mail/somefolder" (but works with the prefix set to ""). Am I missing something? I tried Geo's empty namespace patch, just in case that would help, but it didn't.

[Dovecot] 1.0-test65
by Timo Sirainen 17 Mar '05

17 Mar '05

http://dovecot.org/test/ If dovecot-auth was crashing with you, this release should fix it. I don't know when it did though, I just applied a patch from Andrey Panin with that description :) Fixed also another dovecot-auth crash with Solaris and maybe some other systems. Contains the first attempt of a Dovecot LDA. It's still in pretty ugly shape, but it should work, more or less. I wouldn't recommend using it in production yet. There are two ways to use it: 1. As a normal user. The username is taken from passwd. 2. Giving -d <username> option. This connects to dovecot-auth and requests the uid, gid, home, etc. from it. dovecot-auth's master socket is expected to be in /var/run/dovecot/auth-master but you can override this with -a parameter. To actually create the auth-master socket you'll need to add this inside auth { .. } : socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 } } Dovecot LDA also currently needs dovecot-lda.conf file. Everything that is read from it is just dumped into environment variables internally. You should be able to set pretty much all the same settings in there as exists in dovecot.conf. The most important exception is that instead of default_mail_env there's just "mail". Example dovecot-lda.conf would be: # note that namespaces aren't supported yet.. mail = mbox:~/mail:INBOX=/var/mail/%u mbox_read_locks = flock mbox_write_locks = flock # EOF All this goes away once I get the config process implemented. The actual usage goes something like: /usr/local/libexec/dovecot/deliver -d username < mail_file ie. the mail is read from standard input. Any suggestions if the "deliver" name should be changed and maybe moved to /usr/bin/? Another large change is that I created dynamically growing array implementation with possibility to do compile time type checking. The old code was using buffer_t for arrays, but that got pretty ugly. I changed most of those in lib-index/ to the new array API. I'd be happy if someone changed the rest of them since it's pretty boring and time consuming job :) See lib/array.h for explanation how it works.

[Dovecot] corruption and errors in dovecot-stable

[Dovecot] imap-login zombies
by Robin Breathe 16 Mar '05

16 Mar '05

Running dovecot-0.99.13 on Solaris9/Sparc with ~25k users, we are having regularly recurring problems with large numbers imap-login/pop3-login drones, cycling on poll(). Over the course of 1-2 days, the number of such processes slowly rises to >1000, exhausts resources, and necessitates that dovecot be restarted (having killed all current active and zombie child processes). Nothing of interest seems to be logged with the possible exception of a reasonably high number of aborted logins (~10/hour). Can anyone offer any guidance as to how to track down this bug and help get it resolved? Any help would be much appreciated, as we would very much like to see this resolved in the 0.99 branch. Regards, Robin

[Dovecot] dovecot-auth hangs with IO leak
by Alan Tam 16 Mar '05

16 Mar '05

Hi dovecot, I am using the debian dovecot packages on a system running LDAP. My /etc/pam.d/common-* looks like this, which simply means try /etc/passwd first, and try LDAP using the same password if it is failed. account [success=1 default=ignore] pam_unix.so account required pam_ldap.so use_first_pass account required pam_permit.so auth [success=1 default=ignore] pam_unix.so auth required pam_ldap.so use_first_pass auth required pam_permit.so session [success=1 default=ignore] pam_unix.so session required pam_ldap.so use_first_pass session required pam_mkhomedir.so skel=/etc/skel umask=0002 session required pam_permit.so When many LDAP users login, /var/log/auth.log shows many (expected) error like: (note "pam_unix") Feb 3 18:16:15 eta dovecot-auth: (pam_unix) authentication failure; logname= uid=0 euid=0 tty= ruser= rhost=127.0.0.1 Feb 3 18:16:19 eta dovecot-auth: (pam_unix) check pass; user unknown After recent upgrades from probably 0.99.10 to 0.99.13, these lines begin to appear in /var/log/mail.log: Feb 3 16:31:00 eta dovecot-auth: Login process has too old (123s) requests, killing it. Feb 3 16:31:00 eta dovecot-auth: Login process has too old (124s) requests, killing it. And some more like this, which shows the problem: Feb 3 16:45:23 eta dovecot-auth: I/O leak: 0x8054940 (13) Feb 3 16:45:23 eta dovecot-auth: I/O leak: 0x8054940 (14) Feb 3 16:45:23 eta dovecot-auth: I/O leak: 0x8054940 (15) The problem can be solved by changing /etc/pam.d/dovecot to: auth required pam_ldap.so account required pam_ldap.so session required pam_mkhomedir.so skel=/etc/skel umask=0002 session required pam_ldap.so This change means PAM not fail auth for /etc/passwd again. I think dovecot has some problem dealing with the pam_unix + pam_ldap configuration. Do you have any idea? I am Cc-ing this message to the corresponding bug in Debian BTS. -- Regards, Alan

[Dovecot] Bit of a Newbie Question
by Jud 16 Mar '05

16 Mar '05

Apologies in advance - I'm sure there's something quite obvious I'm not doing correctly, but since I'm unable to resolve the problem myself.... I've installed Dovecot 99.14 on FreeBSD-CURRENT using the Dovecot FreeBSD port. My "network" consists of a cable modem connected to a router which is in turn connected (only) to my computer. My ISP assigns a dynamic IP address. I have ddclient set up to sync the dynamic IP to my hostname and MX via dyndns.org. Local operations (local delivery via Postfix or copying/moving/deleting with Thunderbird) work fine. Mail delivery from remote machines does not seem to work via either IMAP or IMAP-SSL. (That is, test e-mails I send from this [Fastmail] account to my local IMAP server never reach their destination.) Enabling port forwarding on my router for ports 993 and 143 has made no difference. What should I be doing to make this work correctly? Jud

[Dovecot] Strange behaviour with moving mail
by Remy Zandwijk 15 Mar '05

15 Mar '05

Hi All, Sorry to bother you again. I am not too familiar with IMAP yet, so maybe I am asking stupid questions. Here goes anyway: In our (Dovecot 1.0-stable) setup, we have two namespaces: the default namespace, which location is '/var/mailstore/1%u/%u' and the "Mailstorage" namespace, which location is '~/.Mailstorage/'. Now we create a folder called 'Test' in the default namespace and the "Mailstorage" namespace. As far as I know this is possible and not a strange thing to do. When moving an email from the first 'Test' folder to the other 'Test' folder, it appears that everything works like expected, but when refreshing the mailbox, the message is still in the original folder. This happens with a number of different mailclients (which are configured with an empty namespace setting). I guess Dovecot doesn't look at the namespace in which the mail folder is. Is this a Dovecot bug or is this normal behaviour? Best regards, Remy B.T.W: When moving the mail, this is the IMAP conversation: 00029 UID COPY 4 TEST * 2 EXISTS * 2 RECENT 00029 OK Copy completed. 00030 UID STORE 4 +Flags.silent (\Deleted) 00030 OK Store completed.

[Dovecot] Is it possible to regenerate the index files?
by Joakim Verona 15 Mar '05

15 Mar '05

Is it possible to regenerate the index files, on other conditions than the mbox file being read? For instance, it would be nice if I could regenerate the index for a specific mbox whenever procmail delivers mail to it. If theres no existing solution, would it be possible to make a small script with something like "nc" that could send an imap command to dovecot, so that dovecot would rebuild its index for that mbox? If so, which imap command triggers an index rebuild? -- Joakim Verona www.verona.se

[Dovecot] Visibility of .subscriptions and .customflags
by justin 15 Mar '05

15 Mar '05

Hi, I upgraded to test65 from 0.99 (mostly to get the namespace feature) and now it seems my .subscriptions and .customflags are showing up as mail folders in my IMAP client (Eudora). If I try and open those folders, of course I get an error. How can I configure dovecot so that these aren't displayed to my IMAP client? I looked through about 6 months of acrhives and couldn't find it mentioned anywhere. Thanks.

[Dovecot] logging
by F. Even 15 Mar '05

15 Mar '05

I'm curious about exactly what this means in my log: Mar 13 10:56:20 cerebus dovecot: imap-login: Disconnected [130.94.242.20] Mar 13 10:56:51 cerebus last message repeated 177 times Mar 13 10:57:32 cerebus last message repeated 179 times Now...does Dovecot ONLY log the names of users on successful attempts? Is this "Disconnected" log entry an indication someone ran a username/password attack against the imap server and failed to authenticate? If so, is there any way to make this a little more verbose, so I can perhaps see what names, etc. the annoying idiot is throwing against my server....? Thanks.

[Dovecot] (no subject)
by Gabriel Granger 15 Mar '05

15 Mar '05

Hi All, Bit the bullet last night and switched off UW-IMAP and turned on Dovecot. With any migration I've got some teething problems and hoping someone might be able to point me in the right direction. I tested the system using apple's Mail.app which worked fine, no problems at all, but it seems that most of my users are getting problems, i suspect Mail.app is hiding these messages from me. All my users are using ThunderBird 1.0 lastest stable release. Some messages in their IMAP folders are producing the following error. The current command did not succeed. The mail server responded: Error in IMAP command UID: Invalid BODY[_] parameter: Missing '>' in '<16384.-14781>'. it occurs on the same messages in the users email client but happens randomly, it does not stop you from viewing the message, its just pops up with this error. I'm current using IMAP over SSL and using mbox not maildir for IMAP Any ideas or hep would be great as I'd rather not have to roll back out to UW-IMAP Gabe

How old version are you using? :) Or had you changed the default? i had indeed changed the default, thinking that it would be a nice feature to turn on. when the problem first surfaced, i immediately thought of this option. however, since the problem was that applemail wasn't seing the new mail, and this was an option to notify the client that there *was* new mail, i guess common sense got the better of me and i forgot this was something i had changed... > > mailbox_idle_check_interval = 0 > > This shouldn't matter because OSX Mail doesn't use IDLE.

[Dovecot] corrupted inboxes

Hi all, Two users on our system have recently had trouble reading their inbox, and it seems to be a result of their inbox getting corrupted. In the most recent case, their Mailbox file (in /home/eric/Mailbox in this case), has the following as the first line: cnw.igmg-- Here's a piece of the logs below... if you look for "eric", there's a successfully delivery, followed a bit later by a POP attempt by "eric" that returns that the Mailbox isn't in mbox format.

[Dovecot] Authentication to Active Directory
by Chris Wakelin 15 Mar '05

15 Mar '05

Has anybody managed to have Dovecot authenticate to Microsoft Active Directory? I've tried to get it to work using LDAP and the following settings dovecot.conf: userdb = ldap /etc/dovecot-ldap.conf passdb = ldap /etc/dovecot-ldap.conf dovecot-ldap.conf: hosts = rdg-home.ad.rdg.ac.uk dn = cn=bind-user,cn=users,dc=rdg-home,dc=ad,dc=rdg,dc=ac,dc=uk dnpass = XXXXX ldap_version = 2 base = dc=rdg-home,dc=ad,dc=rdg,dc=ac,dc=uk user_filter = (sAMAccountName=%u) pass_filter = (sAMAccountName=%u) I've also tried things like "(&(objectClass=sAMACcountName)(cn=%u))" to no avail. It appears to bind properly, but never finds the account, so login fails. I've had Active Directory authentication working with Squid and with Cyrus SASL/IMAP.

[Dovecot] Drac and Dovecot, almost there ...
by Jon Shoberg 15 Mar '05

15 Mar '05

I have dracd and dovecot up and running and trying to get the two connected. I'm using the FC3 rpms from callimg yum install. I've downloaded the drac patch from http://dovecot.org/patches/drac.c and compiled it with both gcc -Wall -W -shared -fPIC -DHAVE_CONFIG_H -I$dovecot -I$dovecot/src/lib drac.c -o drac.so -ldrac and gcc -Wall -W -shared -fPIC -DHAVE_CONFIG_H -I$dovecot -I$dovecot/src/lib drac.c -o drac.so I get no warnings or errors on the compiling to drac.so. In the conf file I have imap_use_modules = yes imap_modules = /usr/lib/dovecot/imap However, I don't see the module being called. Is there a way to tell. The dracd database (/etc/mail/dracd.db) is not being updated via testing with the drac utilities. Thoughts? Ideas? Below is output from a strace ...

[Dovecot] Dovecot 64-bit and Pine error
by Remy Zandwijk 15 Mar '05

15 Mar '05

Hi all, I compiled a 64-bit Dovecot stable (13-03-2005) version on a Solaris 9 box with gcc 3.4.2. OpenSSL and libiconv are compiled 64-bit also. The configure I use: export CPPFLAGS="-m64 -I/var/tmp/openssl/include" export LDFLAGS="-m64 -L/var/tmp/openssl/lib" ./configure \ --prefix=/opt/dovecot \ --sysconfdir=/etc/opt/dovecot \ --disable-shared \ --with-libiconv-prefix=/var/tmp/iconv \ --without-passwd-file \ --without-shadow \ --without-vpopmail \ --without-static-userdb \ --with-ssl=openssl \ --with-ssldir=/etc/opt/dovecot/cert \ --without-pop3d Dovecot is running fine, all email clients are running fine, except for Pine (4.62). When saving a mail to another IMAP mailbox, Pine report an error message and the logfile shows: Mar 14 16:33:28 tbox dovecot: [ID 107833 local1.error] IMAP(tstud1): utime(/var/tmp/var_mailstore/ t/tstud1/.Drafts/tmp/1110814408.P2681Q0M979308.tbox) failed: Value too large for defined data type Compiling Dovecot in 32-bit, saving mail within Pine is doing just fine. I guess this is caused by maildir-save.c, line 219. Is this a bug in Solaris or Dovecot? -Remy

[Dovecot] dovecot 0.99 + apple mail.app
by sean finney 15 Mar '05

15 Mar '05

hello all, first off, a success story. after much testing and preperation, we've switched from uw-imap to dovecot. i am not kidding when i say that we have experienced an order of magnitude decrease in server load (previously load peaks were 40-60, now they are 3-4). so, suffice to say that the mail admins here are very happy :) one problem that has come up though is particular to apple's mail.app. when a client recieves a new message, they aren't notified that it's arrived, and often even when pressing "check for new mail" they don't see it come in. however, if they move from one mailbox to another, and then back, it shows up. it also shows up if thtey completely quit out of the program and start it back up. i'm going to try and get a packet dump of this to see if i can find out what's happening in the conversation, but figured in the meantime i'd put my feelers out to see if anyone else is having this problem. thanks, sean

[Dovecot] dovecot-stable mbox weirdness
by Matt Howard 14 Mar '05

14 Mar '05

I just tested dovecot-stable from 2005-03-08 and 03-12 and saw the following behavior. All of my mbox folders show is the first message's header. None of the files were truncated (whew, saves a restore). I had 0.99.12.1 installed before this, and just switched back to 0.99.14. Both 0.99.x versions work fine. I removed all of the index files to see if there was a hiccup there, with no effect. System is Slackware 10.0. My package was built with this: http://tinyurl.com/6l2vv

[Dovecot] aha! (was apple mail vs. v0.99)
by sean finney 14 Mar '05

14 Mar '05

it seems that when you say "check for new mail" in apple mail, it sends a NOOP to the imap server to get the response. in uw, the conversation is something like: 25 NOOP 25 OK NOOP completed 26 NOOP * 2796 EXISTS * 7 RECENT 26 OK NOOP completed however, with dovecot, if it has already notified the client that new mail has arrived, it will look something like: * 24 EXISTS * 2 RECENT 22 NOOP 22 OK NOOP completed. 23 NOOP 23 OK NOOP completed. (the counts are different because these are seperate accounts) so evidently, apple mail is too stupid to realize to read info from the server unless it asked for it... so now that i think i have a short-term fix (disabling notification for new mail server-side), i can breathe a sigh of relief. for a long-term fix, would it be possible to have the server always notify the client of new mail after a NOOP? thanks, sean

[Dovecot] Authentication error after authentication query (for Eudora 5.2 on Mac)
by Tim Alberts 14 Mar '05

14 Mar '05

Greetings all, I'm a new user of Dovecot and want to say thanks for the great software. I am having a problem at the moment. I run a heterogeneous network with windows and Mac clients logging into a Fedora Linux 2 box running sendmail and previously UW-IMAP, but now Dovecot. I am using strictly pop3, plain authentication with mbox format. Every computer in the network is working fine with this sytem, except 1. A mac running Eurdora mail 5.2. It gives me an Authentication error every time it tries to get mail. I telnet into the server and when I skip the AUTH process and just log in, the server works fine as follows: [talberts@localhost ~]$ telnet mail.inside.msi 110 Trying 192.168.0.3... Connected to mail.inside.msi (192.168.0.3). Escape character is '^]'. +OK dovecot ready. user tdazey +OK pass ****** +OK Logged in. quit +OK Logging out. Connection closed by foreign host. [talberts@localhost ~]$ However, when I do the following session: [talberts@localhost ~]$ telnet mail.inside.msi 110 Trying 192.168.0.3... Connected to mail.inside.msi (192.168.0.3). Escape character is '^]'. +OK dovecot ready. auth cram_md5 -ERR Unsupported authentication mechanism. auth login -ERR Unsupported authentication mechanism. auth plain + user tdazey -ERR Authentication failed. user tdazey +OK pass ****** +OK Logged in. quit +OK Logging out. Connection closed by foreign host. [talberts@localhost ~]$ I don't need any authentication except plain. However, when the client queries the settings, it fails the login. I tried this on multiple accounts with the same results. What do I do to fix this?

[Dovecot] Dovecot, pam and OpenLDAP
by Rune Hamnvik 14 Mar '05

14 Mar '05

Hello We have a Dovecot installation using only pop3 where auth data is stored in OpenLDAP and accessed using pam. With Fedora 2 everything has worked fine, but when we upgraded to Fedora 3 we started to get problems. After a while a lot of dovecot processes existed, and error messages was logged in maillog telling that the processes was too old. Then some error messages telling about memory leak was logged. Our /etc/pam.d/dovecot looks like this: #%PAM-1.0 auth required pam_nologin.so auth required pam_stack.so service=system-auth account required pam_stack.so service=system-auth session required pam_stack.so service=system-auth Any idea what is happening?

I've always had to drop my IMAP connection and reconnect to recognize changes I've made on the server side. A kill -1 to dovecot will only reload the server process and the login auth processes...it won't kill your already established IMAP connection, which as far as I can tell, keeps using old settings. If you are having that many problems, delete all of your subscriptions files and dovecot caches and start from scratch. I've had to do it a few times to get things to work as expected.

[Dovecot] Restrict Imap access
by Sergiu Zaharia 14 Mar '05

14 Mar '05

Hello. I need to restrict access to IMAP ports to a few users, so that all users can use POP3 and just a few of them will be able to access IMAP. I use secure connections POP3s and IMAPs. Is it possible? Also... When I connect to the Dovecot server using Outlook (IMAPs) I get a Warning message,something like: "The server you are connectiing to uses a non verified protection certificate. A chain of certificates ...so on ( I can't translate :) ) Continue using the server? " How can I fix that warning? Thanks

Do you even see the mailbox list? Maybe kmail got somehow confused and recreating the IMAP account entirely would be easiest way to fix it.

[Dovecot] pop before smtp with 'exact' and 'exim4'
by Jools Smyth 13 Mar '05

13 Mar '05

Hello, I just thought I would write this in case its useful to anyone. I've used dovecot for a while, as its so easy to set up, its fast and it and just "works". I recently wanted to be able to send via my server after pop3s authentication. I'm also running debian (testing) which utilises exim4 by default. I found no information about how to do it with this combination of software so went about sorting it out myself. First I got exact : (a pop before smtp daemon) http://adju.st/dist/exact/ After compiling and installing i edited its /usr/local/etc/exact-servers.conf It doesn't support dovecot's log format out of the box, so i created a regular expression entry for it. <server dovecot> order username,address match (Login): (.*) \[(.*)\] </server> I then edited its main configuration, (/usr/local/etc/exact.conf) changing only the user its running on (default mail/mail) to Debian-exim/mail. (so that the state file it creates can be read fine by exim4) I also changed the mail log ownership so that group mail can read them, /usr/local/var/state/exact to drwxr-sr-x 2 Debian-exim mail 1024 Mar 13 16:39 exact and /usr/local/var/run/exact to drwxr-sr-x 2 Debian-exim mail 1024 Mar 12 21:54 exact Exact's exim documentation is not for the most recent version, so I had to locate the correct line to modify. I went into the exim4 configuration files. I use the debian split format configuration. In the file /etc/exim4/conf.d/acl/30_exim4-config_check_rcpt there is a line near the bottom which reads accept hosts = +relay_from_hosts I changed this to accept hosts = +relay_from_hosts : net-lsearch;/usr/local/var/state/exact/rela y I then just set exact to and start/stop in /etc/init.d/exim4 thats all!

Feb 27 03:10:42 eta dovecot-auth: Login process 8 disconnected Any clues what it means? Recently I have to restart dovecot several times a day, after I have report that all users cannot login. I am running Debian sarge (2.6.8 kernel) with dovecot version 0.99.14-1 with auth_verbose and auth_debug on. -- Regards, Alan

[Dovecot] Errors when searching large folders

I am getting errors from dovecot when trying to search, in large Maildir folders. The folder has 40454 messages and is 371MB in size. The email client is squirrelmail 1.4.3, running on FreeBSD-current. I've had this problem before, and i posted a message here. The author said he would fix this, but it seem the problem is still not resolved. This is the error i get: --- ERROR : Connection dropped by imap-server. Query: SEARCH CHARSET ISO-8859-1 ALL BODY {5} hello BODY {5} there --- At this point the HD led remain on for another 30 seconds or so. Thanks.
