[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

20 Apr '05

Hi, I have some problems with my connection from outside to POP3/IMAP... As far as I can see every should be set corret. Currently I use version 0.99.11-1.FC3.4 installed from an RPM-file. I tried to debug the signin process. It's always saying bad password... What encryption can DoveCot read? Currently my password is encrypted with md5crypt... Regards Anders

[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] Fetching POP3 Mail with Dovecot
by Eurig Jones 18 Apr '05

18 Apr '05

Hi, I have a small personal server here which I've managed to successfuly install the dovecot server onto. What i'm hoping to do is download POP3 mail from 1 or 2 accounts using the dovecot server so I'll be able to read all from the dovecot server... Is this possible? thanks! Eurig

[Dovecot] attr_names in test67
by Thomas Hummel 18 Apr '05

18 Apr '05

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 17 Apr '05

17 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> -----------------------------------------------------

Hi dovecot-0.99.11-1.FC3.4.i386.rpm on FC3 when i create a user account with pop3 email i find that if i don't send and email to the account (so that sendmail creates the file under /var/spool/mail/testuser) where "testuser" is the users username. If the user logs in with Outlook or Outlook express they get an error and maillog shows.

[Dovecot] dovecot and evolution
by Dennis Lambe 17 Apr '05

17 Apr '05

I am using dovecot 0.99.13 and Evolution 2.0.2 on Fedora Core 3. Recently, Ximian stopped being able to access my local INBOX via IMAP, failing with the following error: Error while Opening folder imap://malsyned@localhost/INBOX. Incomplete server response: no information provided for message 1. I got a transcript of the conversation between Evolution and dovecot. The relavent section follows: ========================== [>>] Reading from client A00015 SELECT INBOX [<<] Reading from server * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 7668 EXISTS * 0 RECENT * OK [UNSEEN 7660] First unseen. * OK [UIDVALIDITY 1101063317] UIDs valid * OK [UIDNEXT 334080] Predicted next UID A00015 OK [READ-WRITE] Select completed.

The headers it gives for message #2 are the same as the first message in my mailspool, and the headers for message #3 are those of the second message in my mailspool. It goes on from there. 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
by Rich West 16 Apr '05

16 Apr '05

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

How can I configure the dovecot for working with maildir's through NFS? If I add option "index_mmap_invalidate = yes" (as in doc/nfs.t) then in log I have this message: "Error: Error in configuration file /etc/dovecot.conf line 296: Unknown setting: index_mmap_invalidate" If I try to get the mail without option "index_mmap_invalidate" then I have in log this message: "Error: POP3(butyrev.lk): mail_index_lock_fd() failed with file /var/mail/sam-butyrev.lk/dovecot.index.log: No locks available dovecot: Error: POP3(butyrev.lk): mail_index_wait_lock_fd() failed with file /var/mail/sam-butyrev.lk/dovecot.index.log: No locks available dovecot: Error: POP3(butyrev.lk): Couldn't open INBOX: Internal error occured.

[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 11 Apr '05

11 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 09 Apr '05

09 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 07 Apr '05

07 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.

[Dovecot] 1.0-test66
by Timo Sirainen 07 Apr '05

07 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] Archiving Dovecot format maildir
by Leslie Viljoen 07 Apr '05

07 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 07 Apr '05

07 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 07 Apr '05

07 Apr '05

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

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

07 Apr '05

Hi, i'm quite new to dovecot. i built it from the stable-1.0 sources. i have the following error messages in syslog when trying to launch dovecot: dovecot: Dovecot v1.0-stable starting up dovecot: auth(default): Unknown passdb type 'pam' dovecot: Auth process died too early - shutting down dovecot: child 373 (auth) returned error 89 i googled a bit, and found some posts on this mailing list describing the same problem, and the answer is that pam support is not compiled in. So i tried to ensure pam support would be compiled: i made sure that i have the proper libs. I work on debian so i did: apt-get install libpam-runtime libpam-modules apt-show-version tells me the version numbers installed: ... libpam-modules/testing uptodate 0.76-22 libpam0g/testing uptodate 0.76-22 libpam-runtime/testing uptodate 0.76-22 libpam-ldap/stable uptodate 140-1 ... my configure line is as follows: ./configure --sysconfdir=/etc --localstatedir=/var --with-ssl=openssl --with-pam when running configure, the only line related to pam is the following: checking for pam_start in -lpam... no and at the end of the configure script i get the following summary: Building with user database modules : static passwd passwd-file checkpassword (modules) Building with password lookup modules : passwd passwd-file shadow checkpassword (modules) So it seems that pam support is not built in. What is the lib i am missing ? Any help appreciated, thanks -- \|||/ (o o) Matthieu Imbert ooO-(_)-Ooo------------------------------------------ équipe administration réseau et systèmes Ecole normale superieure lettres et sciences humaines 15, Parvis René Descartes BP 7000 69342 LYON cedex 07 tél 0437376127, secrétariat 0437376122 fax 0437376123 contact équipe réseau et systèmes <reseau(a)ens-lsh.fr> contact personnel <matthieu.imbert(a)ens-lsh.fr> -----------------------------------------------------

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

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

[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? Thx David
