[Dovecot] what does this mean: Warning: Error in custom flags file / Corrupted Indexes
by rick tait 18 Sep '05

18 Sep '05

Hi everyone: I am seeing a whole LOT of these messages in my dovecot logfile: imap(rickt): Sep 12 17:14:03 Warning: Error in custom flags file / home/rickt/mail/.imap/TRASH/.customflags: Duplicated ID 0 imap(rickt): Sep 12 17:14:03 Warning: Error in custom flags file / home/rickt/mail/.imap/TRASH/.customflags: Duplicated ID 1 and also these: imap(mbwnews): Sep 12 17:10:16 Error: Corrupted index file /home/ mbwnews/mail/.imap/INBOX/.imap.index: used_file_size larger than real file size (2016 vs 1608) imap(mbwnews): Sep 12 17:10:18 Error: Corrupted index file /home/ mbwnews/mail/.imap/INBOX/.imap.index: used_file_size larger than real file size (2016 vs 1608) And not just referring to my inbox, other users as well. I hava bog standard install of 0.99.10.8, on an openbsd 3.6 box. every now and then i get an error from my or my users' IMAP email client saying that it couldn't access a particular inbox. a few clicks of "OK" or "Cancel" etc and the problem seems to go away. all kinds of errors (similar to above) in the imapd logfile though, seem to correspond with the timing of the abovementioned IMAP mail client errors. one thing: my users DO use procmail, so there is a chance that their IMAP client might have a mailbox open that procmail may be trying to append to. i wonder if this is a locking issue? i guess what i'm asking is - 2 thing: 1) how can i get these pesky imap client errors to go away so my users mailboxes can be successfully selected? 2) what do the indexing errors mean? are the 2 things related? Thanks so very much in advance everyone! Best, Rick. rick tait | e: rickt(a)rickt.org | t: 323.829.5703

[Dovecot] Timeout while waiting for lock....
by Rob Frohne 16 Sep '05

16 Sep '05

Hi, I'm very new to administering mail, and this is surely a newbie question. I have my own IMAP mail server because I use my email as a way of filing important things, and I subscribe to a number of lists that I like to archive. I have about 40 mailboxes with up to 80,000 messages in some, and one with 40,000 messages is almost a Gigabyte in size. The total size is around 4 Gigabytes. Things were working quite well until I upgraded to OS X 10.4 and its new Mail.app mail client and then everything was too slow. I was using the UW IMAP server (2002d if I recall right) and Mail.app 1.3.9. I tried upgrading the server to the latest, but it didn't improve things noticeably. I swapped to dovecot 1.0alpha1, and used the mbox format, but that wasn't any better. I read that Maildir format was better, so I converted my mail to that format and tried that. It didn't seem much better. I tried to compile Cyrus on OS X and ran into all kinds of difficulty. I finally tried Cyrus on a Linux box, and turned off all my rules that move messages around. In comparing this to dovecot on my OS X box, Cyrus loads the messages significantly faster. I think there are some problems with my dovecot setup though. My mail.log is filled with this type of thing.

Can anyone suggest something to fix my problems, besides deleting all my email? Thanks, Rob

[Dovecot] SSL/TLS stopped working in 1.0 alpha2
by Andy Cravens 15 Sep '05

15 Sep '05

I have both 1.0 alpha1 and alpha2 installed on my test mail server. SSL/TLS does not work on alpha2. I'm using the same config file for both. No errrors in dovecot.log either. Is there a way to increase debugging info without recompiling?

[Dovecot] Dovecot-LDA problems (CVS version) Signal 11 and empty 'mail' dir
by Steffen Kaiser 14 Sep '05

14 Sep '05

Hello, I'm trying dovecot-lda (deliver.c has CVS version 1.18). When I try to deliver a mail, an empty directory is created name $HOME/mail. This is neither the configured (via LDAP) nor the default "mail" setting in the /usr/local/etc/dovecot-deliver.conf. When the $HOME directory does not exist, but the user itself: Sep 1 11:47:12 localhost deliver: mbox: Can't create root IMAP folder /home/skaise2a/mail: Permission denied Sep 1 11:47:13 localhost sm-mta[4684]: j819lCgd004682: SYSERR(root): mailer local died with signal 11 Default mail: mail = maildir:%h/.mailboxes:INDEX=/usr/local/var/spool/dovecot/indexes/%Lu Configured via LDAP for user skaise2a: maildir:/mailcache/skaise2a:INDEX=/var/cache/dovecot/indexes/skaise2a:CONTROL=/var/cache/dovecot/control/skaise2a I have only found the error message in dovecot's src/lib-storage/index/mbox/mbox-storage.c function create_root_dir(). The Dovecot logs indicate that dovecot-lda is requesting the information from it and the message is - once the empty directory could be created - delivered into the configured IMAP root.

Locking _does_ work for postfix and dovecot (discussed with Wietse, partly by mail). Any idea? As an alternative, is there a way of handling the problem better?

dovecot-v1.0-alpha build failed for Solaris 11 (OpenSolaris Nevada). The problematic line is in socket.c line 228. The fix should be to change SOL_TCP to IPPROTO_TCP found in netinet/in.h. This change should work universally on all platforms. Gary

[Dovecot] An alternate "dovecot-auth" daemon using cyrus-sasl
by buc 12 Sep '05

12 Sep '05

We use dovecot in a heterogeneous environment (Windows/Linux desktops and Linux servers). For unified authentication we use a sheaf "Samba/Openldap" (i.e., Samba NT domain with openldap backend and pam/nss_ldap for Linux). Windows users are authenticated well everywhere, but there is one old issue. As "SPA" (NTLM) against NT domain is not supported by dovecot, it is necessary to use default "plain" method. In addition to security problems, it does also a problem of password unification. Each time a user changes the password, he should do it one more time for the mail program. I know that dovecot supports NTLM, however against local database only (not for NT domain controller). In early versions support of cyrus-sasl (which supports NTLM now) had been incorporated, however it like not work and now is removed. Fortunately, there is a possibility to substitute dovecot-auth executable. Therefore I have tried to make an alternate variant of dovecot-auth, which supports all that we need. For us, it seems to be more useful to create an auth daemon using cyrus-sasl, rather than to add domain support to existing ntlm code. First of all, it is easier for implementation. Besides it enables use of all mechanisms supported by cyrus-sasl (present and future), including GSSAPI. Anyway, it will be the useful additive to dovecot. I have made appropriate patches for both dovecot-1.0-stable and dovecot-1.0.alpha1. The idea is to copy "src/auth" to "src/auth-cyrus", strip all unneeded from newly created directory and add cyrus-sasl support. The resulting code probably looks not so elegantly as if it has been written separately, however this way allows to not make a lot of things from the scratch. The patch against 1.0.alpha1 is here: http://dmitry.butskoy.name/dovecot/dovecot-1.0.alpha1-cyrus.tar.gz . To be more readable, it is not a flat patch (due to a lot of whole files add/remove). It is a tarball with 3 files: a list of files to initial copy from auth/ to auth-cyrus/, a patch for resulting tree, and a script which automates this steps (:-)). (The script should be run in the root of the main source, i.e. a dir with src/ and doc/ subdirs). I already have successfully tested this patch with PLAIN method. However before testing of other methods, it would be desirable that somebody have looked at it. Whether someone could check up my patch (just fluently having read), at least for obvious bugs and typos?

[Dovecot] Dovecot feature request: move /var/mail/uid to INBOX
by Steffen Kaiser 12 Sep '05

12 Sep '05

Hello, UW-Imap has a (questional, but for me useful) feature to slurp all mails pending in /var/mail/uid into the user's INBOX whenever the user successfully logs on and the INBOX is not configured as /var/mail/uid. The usefulness for me is that users have a relatively small quota, so the noisy "over quota" messages pop up for everyone now and then, regardless how frequent one reads the mail. When I now set a large quota for the "pending INBOX", where the user (aka dovecot) can only delete mails from, I circumvent those messages, prevent that users use the (large) INBOX as yet another place to pile up data (the user does not know about the pending INBOX at all) and let the users have "full" control over their folders. The disadvantage is that it works for "real" users only. Another disadvantage is that one would expect "LDA"-features in the server portion of Dovecot, e.g. Sieve :-), or the server would need to spawn the Dovecot-LDA somehow. (Next thing is that, currently, the mails are delivered into the home directory of the users, what leads to several annoyances when someone is away for some time and finds his home directory locked, because the mass of mails locked the directory. Mostover, those IMAP servers I ran so far didn't allowed the user to delete a mail via IMAP often, because some temp or arbitary file couldn't created in the IMAP root. Because the user is already logged on onto Dovecot, there should be less problems deleting mails when the quota exceeds while slurping them in. At least I had extremly good experiences with this mechanism, when I used UW-Imap and the INBOX was located as mbx in the user's homedirectory.) Bye, -- Steffen Kaiser

[Dovecot] reading subfolders with mail.app

Hi all, I have been having a hard time using Fedora Core 4 with dovecot +sendmail. Namely, I cannot read my home dir's procmail filtering dir (where I have some subfolders) in ~/mail. I cannot create mailboxes either. I'm wondering if this is a client issue, and whether I need to switch to Maildir, which I'd like to do, but don't know how to with sendmail (with postfix, it's a piece of cake). Any advice on what my problem is? I'm all ears! regards, Patrick

[Dovecot] 1.0alpha2 released
by Timo Sirainen 12 Sep '05

12 Sep '05

Changes: - Some cache file corruption fixes (shouldn't be any left?) - Some index file fixes with mmap_disable=yes - Some mbox syncing fixes - Timezones in mbox From-lines were handled wrong - Added pop3_reuse_xuidl setting. Patch by Chris Wakelin - "stack frame changed" crashfix for FETCH BODYSTRUCTURE - Added %R (reverse string) and %H (hash string) variable modifiers. These can be useful if you want to automatically split users to multiple partitions (eg. %3RHu gives values 0..2 based on the given username). See doc/variables.txt for more information. The POP3 bug mentioned in ChangeLog doesn't actually exist, so don't be alarmed by it :)

[Dovecot] Do index files need removing when upgrading 1.0-stable to 1.0-alpha1 or later?
by Chris Wakelin 11 Sep '05

Hi Timo, Just a quick question: do index files still need removing when upgrading from 1.0-stable (as in the testXX series) or will Dovecot regenerate them automatically? I'm expecting to go with 1.0-stable on Tuesday for my 20,000 users (as that's what I've been testing), but if we see lots of index issues, I may want to upgrade to alpha1 (or later) fairly soon afterwards and it would be annoying to have do delete thousands of indexes!

[Dovecot] subscriptions or .subscriptions?
by Andy Cravens 11 Sep '05

11 Sep '05

I may have found a problem with the documentation concerning the subscriptions file. On the Dovecot web site there is a document that outlines the conversion from UW IMAP to Dovecot. The document says Dovecot's folder list is stored in ".subscriptions" However, I have found that Dovecot's folder list is really "subscriptions" without the preceding dot. Did Dovecot version 1.0.alpha1 remove the dot from the subscriptions filename? .subscriptions does not seem to work at all. http://wiki.dovecot.org/moin.cgi/Migration#head-5dde807bf059dea93fc2303e202…

[Dovecot] Problem in dovecot 0.99 - login username case sensitive create fake maildirs

Hello, I have noticed a weird behaviour in dovecot 0.99 which, I hope, is not replicated in 1.0-alpha. First I have to say that it works very well. So if I login with user foo(a)bar.com, the maildir is created. But when I log in with User FOO(a)BAR.COM, or FOO(a)BAR.com, then two other maildirs are created. Authentication is ok (I'm using mysql backend) but no mails are obviously found. Maybe a solutions would be adding some config item to turn lowercase the maildir path or authentication tokens (received from client) at login time. Or maybe I am missing something. Is there a solution for this problem out there ? Thanks, Massimo

[Dovecot] POP3 problem about multi users from one IP address concurrent
by Yi Xuan 11 Sep '05

11 Sep '05

Hi,all I have a POP3 problem about multi users from one IP address concurrent. [Issue description] The network architecture is as following. I have setup a mail server(sendmail/dovecot) in PlaceA with IP_A. And about 6 users are receving mail from the same IP_B( NATed public IP) in PlaceB. Their mails are many( about 1Mb/hour each) and ususally set fetch time as 10min/fetch. Then they complain that their mails often cannot be downloaded. [Reason investigation] I noticed that 1.when one of them fail to fetch mail. All TCP IP connection between IP_A and IP_B will be RST.which means that http/ssh/pop/smtp all not work for a while. And after about 10 minute, the http/ssh can work well. 2.I have asked them to backup and delete pop accounts and use webmail through imap provided by dovecot.And that seems work well but inefficient. I think this maybe because of multi users from one IP address concurrent, [Question] Would you pls provide some suggestion or solution about this issue? Is this a bug of dovecot or just a mis-configuration I don`t know? Thanks in advance for any advice. Best regards, Yi Xuan

[Dovecot] Fatal: EOF while reading environment from master Error
by Phil Bettinson 11 Sep '05

11 Sep '05

Hello all! I guess it's a standard reason for joining a mailing list, but I have a problem. For some reason, whenever I try to start dovecot, be it from the xinet.d or from the commandline, I get this rather bizzare error. I can't even work out what it means, so I can't even begin to debug it. There is nothing extra in /var/log/messages, so I'm out of ideas. I've tried it with the default config, as well as with a config that I adjusted to fit the environment. I'm currently out of ideas. I did notice that there is a brief thread on this in the mailing-list archive, but it doesn't seem to point to a solution. Hopefully someone can help. I'm running it with the command /usr/local/libexec/dovecot/imap-login I am using the 1.0.alpha1 version, running on RedHat AS 3. thanks in advance.

[Dovecot] Dovecot-alpha1 and Thunderbird Sent problems
by Nicholas Young 09 Sep '05

09 Sep '05

I have dovecot 1.0alpha1 setup in a semi test environment running on Solaris 2.6. When using Thunderbird 1.0.6 from Windows occasionally the client will hang after sending a message and before copying it to the Sent folder on dovecot. Sendmail logs indicate that the message has been sent correctly. The mail directory is not shared over NFS. It is in maildir format. Restarting Thunderbird and sending exactly the same message will work. This seems to imply that it is not message dependant. Once the error has occured once it continues to occur until the client is restarted. We have file system quotas however they are very large for a very small amount of mail. The filesystem is about 80% free space and about 98% free inodes. I cannot replicate the issue under Linux using Thunderbird that is current for FC3. Some hacked version 1.0.2-1.3.3 Imap workarounds turned on under dovecot are outlook-idle for imap. The issue has not been seen under Outlook. Outlook is using a local Sent-Items folder instead of an Imap one however. The connection is running over SSL so I can not sniff the traffic on the wire, I have not tried using the rawlog settings yet. I plan to start this now, however the sporadic nature of the problem may delay useful information from here. The dovecot logs are not showing error messages, just: dovecot: Sep 09 09:24:35 Info: imap-login: Login: user=.... TLS Any suggestions on where to start would be great. This issue was not reported to me when running dovecot-1.0-stable-20050718. Thanks for any help/suggestions on where to go from here. -- Nich

[Dovecot] Ip addr + login name
by mike 08 Sep '05

08 Sep '05

Hi everybody, Is there a way to bind client ip address that connects to pop3 with the login name? For example if the client ip address is 192.168.2.40 then his login name is 'test' and he can log in with only that account name. I think it is possible to do it with an external authentication program. Thanks.

[Dovecot] More verbose logging of POP transactions?
by Philip Hallstrom 08 Sep '05

08 Sep '05

Hi all - I'm brand new to dovecot (0.99.14 on freebsd 5) and am just playing with it a bit. POP works just fine, but the only thing that shows up in my logs is this: Sep 7 11:46:25 freebsd5 pop3-login: Login: philip [10.28.61.200] Thought maybe syslog was quietly eating things, but told dovecot to use it's own log file and it didn't improve. Is there a way to turn on more detailed logging about what the user did? Along the lines of what uw-imap's pop gives you in terms of number of messages available, downloaded, deleted, etc.? I'm also interested in how much was transferred size wise... If I mised it in the conf file just let me know, but I didn't see anything... Thanks! -philip

[Dovecot] Dovecot - IMP - POP autentication problem
by Carlos Bergero 07 Sep '05

07 Sep '05

Hi, Recently I have to rush one of my mail servers to a new installation, actually GNU Linux/Debian Sarge, the system run dovecot 0.99.14 for pop and imap, and the web server, other machine, uses horde2/imp3. The problem is the following, pop clients including the imp3 cant log properly apparently, the even when a connection is made to pop3 dovecot trys to make a secure connection, I found this after sniffing the connection between the web server and the mail server, for some reason, imp cant handle it well and the some clients like OutLook also have troubles working this out. For now I work around this problem by disabling the ssl/tsl support, but that's not the solution I need. So the question is can I disable this feature without loosing the secure connection and how can I do it? Cheers, rak

[Dovecot] 1.0alpha1: new assert/core
by Jeff A. Earickson 07 Sep '05

07 Sep '05

Hi, I saw a new assert and core dump today in 1.0alpha1. Setup is Solaris 9, dovecot built with gcc 4.0.1, running as imap server for mbox format. The syslog said: IMAP(user): file message-body-search.c: line 393 (message_body_search_ctx): assertion failed: (input->v_offset <= part->physical_pos) A gdb analysis of the core dump is attached. BTW, I save core dumps in case you need further debugging done for an assert. On another note, I have also had issues with dovecot locking up with "Too many open files" syslog error messages. Last night, after several hours of "too many open files" complaints, the master dovecot process just died -- no core dump and no complaint to syslog. Per advice of the list, I have doubled the rlim_fd_cur and rlim_fd_max kernel parameters and rebooted my imap server. I also saw in my syslog: Sep 6 16:48:53 emerald dovecot: [ID 956436 mail.error] pipe() failed: Too many open files Sep 6 16:48:53 emerald dovecot: [ID 257797 mail.crit] dup2(stderr) failed: Bad file number With students back, they have been giving dovecot a real hard workout.

In 1.0 there are two executables, mail_executable launched for logins, and (from memory) auth_executable launched at daemon start, so I suppose login_executable is the wrong one :-) I diagnose the error you get as meaning that the space is not ed separat out, and that dovecot tries to fork the executable named /usr/libexec/dovecot/popbsmtp.sh /usr/libexec/dovecot/pop3-login which obviously won't work. > Permissions are 777 on the popbsmtp.sh script.

Problem with direct SQL is that I can't manage to make dovecot execute two SQL statements. If you're using a db with stored procedures you could maybe squeeze through that loophole, but your best bet is to find out what user_executable should be (maybe the same thing?) > Back to pop-before-smtp which doesn't work either, but it works better. :) :-) HTH

[Dovecot] 1.0-test75 and roadmap for v1.0
by Timo Sirainen 07 Sep '05

07 Sep '05

http://dovecot.org/test/ Keywords are finally stored in maildir filenames and listed in "dovecot-keywords" file. It should be possible to just rename 0.99.x's .customflags file to dovecot-keywords (but it can't be renamed back after modification). Also fixed another uid/sequence mixup bug with setting keywords in general (in mbox too). Fixed SHA1 checksum generation with big-endian machines (used only in passwords). I think I'll forget about the master/config rewrite for a while and leave it for Dovecot v2.0. That would mean the next release will be called 1.0-alpha1. After that there should be only bugfixes and some smaller features and optimizations left. I looked through my TODO and found the following missing features / optimizations that pretty much have to be done before v1.0. Anything important missing? - keywords: - add some limits to how many there can be - send FLAGS/PERMANENTFLAGS untagged replies when they change (required by IMAP RFC) - remove unused keywords from keyword list? (only when adding new ones) - mail cache file - cache _all_ headers that are marked to be cached when headers are being parsed, not just the ones client is requesting at that time. - compression should drop fields with last_used < (latest_mail_index_date - month) - when parsing mbox or saving message, parse the mail through index-mail so things gets saved into cache immediately - mbox - when we're updating flags with lazy writing, we're still parsing the mbox, just not writing to it! - always add empty line after mail. - make the parser require it too? syncing should make sure there always exists two LFs at end of file. raw-mbox-stream should make sure the last message ends with LF even if it doesn't exist in the file - COPY doesn't work to same mailbox (lock assert crash) - keep mbox lock for two extra seconds after sync to make sure we notice changes made by other mbox writer software - maildir - hardlink copying doesn't update indexes (does it even work?) - deliver needs quota integration somehow so it returns out-of-quota failure as fatal instead of temporary Probably after v1.0: - Full NFS support - Try to handle out-of-quota/disk space situations well

Maybe it's a general understanding problem on my side, but let's see :-) I would like to have my mail stored in Maildir format below ~/.maildir/, which works fine so far. I want any (sub)folders to be created like this: ~/.maildir/ /cur /new /tmp /.Folder/ /cur /new /tmp /.Subfolder/ /cur /new /tmp BUT ;) Dovecot seems to disregard my namespace settings: --8<--[ /etc/dovecot.conf ]--8<-- default_mail_env = maildir:~/.maildir:INDEX=MEMORY namespace private { separator = / # prefix = # location = maildir:~/.maildir inbox = yes hidden = no } --8<-- Every new (sub)folder I create is stored as ~/.maildir/.Folder resp. ~/.maildir/.Folder.Subfolder in the filesystem. Are namespaces the right way? Is it possible at all? Thanks in advance. -- Wolfram Schlich

For example: {NTLM}69943C5E63B4D2C104DBBCC15138B72B For more information read here: http://wiki.dovecot.org/Authentication > >>Windows users are authenticated well everywhere, but there is one old > >>issue.

[Dovecot] upgrading: should I and what will change?
by Joshua Paine 06 Sep '05

06 Sep '05

I've been running dovecot 0.99.11 with postfix and postgresql in a production environment with about 25 real users and a couple hundred aliases split over a few domains for nearly a year now. No problems of any kind that I have noticed. Should I upgrade to the latest dovecot? What changes, if any, will I have to make? I've looked through the archives for a couple months without seeing much, and I don't see anything specific in the docs about upgrading. -Joshua <><

[Dovecot] how to migrate from one server to another?
by Bram Mertens 06 Sep '05

06 Sep '05

Hi I have purchased and installed a new PC and would like to transfer my mail (in Maildir format) to it. Are there any precautions I must take before copying the mail over? I will disable mail delivery temporarily so no new mail gets written to disk but I don't know if dovecot has to be stopped before copying/editing mail for backup or migrating purposes. Anything else I must pay attention to? TIA Bram

[Dovecot] dovecot + openwebmail
by Peter McEvoy 05 Sep '05

05 Sep '05

Hi, I'm trying to add some sanity to a badly thought out mail system that, for various reasons, cant be fixed from the bottom up at this moment in time. The system is debian sarge, exim 4.5, doing virtual domains and delivering into mboxes in /var/spool/virtual/$domain/$user , there is webmail access and this allows user to create folders in (dont shoot me!) /etc/openwebmail/users/$domain/$username/mail/ , the files in this directory appear to be mboxes in that each mail begins with a From: line, the naming of these files is completely arbitrary. Im trying to add imap access that would ideally give users access to the mail in /var , and also in the openwebmail dirs, though the latter is not essential, just desirable. All mails are owned by user mail. I've installed dovecot-imapd version 0.99.14-1, but if this doesnt have the namespace additions from version 1.0-test, I can easily install that. Reading the wiki, it seems I can achieve this with namespaces, something like namespace private { separator = / inbox = yes prefix = location = mbox:/etc/openwebmail/users/%d/%u/mail:INBOX=/var/spool/virtual/%d/%u } But, Im not quite sure where this would go in the config file, going by the example config you can just shoehorn them into the middle of the file, but I'm not 100% sure... I had been trying to use things like.. default_mail_env = mbox:/var/folders/%d/%u:INBOX=/var/spool/virtual/%d/%u:INDEX=/var/indexes/%d/%n Having created the necessary folders in /var , but I didnt have much success (the authentication part worked straight away using my passwd file), And having read more and been told about namespaces on the irc channel, it seemed like I should go that way anyway. If anyone could give me a steer in the right direction, or even tell me i'm wasting my time (tho dont bother telling me how much better maildir etc is, i know!) Thanks for your time. -- Pete
