[Dovecot] Log data on dovecot-auth socket
by Koen Vermeer 11 May '07

11 May '07

Hi, Is there any way I can monitor or log the data that is being received/sent on the dovecot-auth socket? I'm trying to debug some authentication stuff, and monitoring the conversation would be very useful. Thanks! Koen

[Dovecot] No authentication sockets found
by Stewart Dean 11 May '07

11 May '07

Thunderbird (2.0) is all of a sudden checking mail server capabilities and keep posting a popup saying: "Mail Server imap.bard.edu is not an IMAP4 mail server". To the best of my knowledge, neither Tbird nor DC have been updated, though the DC imap host was rebooted today 3 hours ago. Any info on what this is about? DC is currently serving out of a special port and in evaluation list....I can't imagine that this message would please the user community! Killing and restarting dovecot appears to have at least temporarily stopped this behavior. Also and perhaps related, I am seeing a syslog message: imap-login: No authentication sockets found child xxxxxx (login) returned error 89 using SSL encrypted IMAP service Background: DC 1.0, invoked from /etc/rc.local during boot. After stopping and restarting DC, things seem to work again. As per an old problem, I checked /var/run/dovecot, but it was empty with plenty of space. FWIW, the owner/group for login dir (/var/run/dovecot) is dovecot:dovecot, perm 755, while /var/run/dovecot/login is root:dovecot, 750. Host is running AIXV5.3 TL5 SP6 (latest level), DC is compiled with IBM's AIX for C, V6.0 dovecot -n output > # /usr/local/etc/dovecot.conf > listen: *:10143 > ssl_listen: *:10943 > disable_plaintext_auth: no > verbose_ssl: yes > login_dir: /var/run/dovecot/login > login_executable: /usr/local/libexec/dovecot/imap-login > verbose_proctitle: yes > first_valid_uid: 200 > mail_location: mbox:~/mail:INBOX=/var/spool/mail/%u:INDEX=/var/dcndx/%u > mail_debug: yes > mbox_dirty_syncs: no > mbox_lazy_writes: no > auth default: > verbose: yes > debug: yes > passdb: > driver: pam > userdb: > driver: passwd Do I need to set an O/S or SSL max for authentication sockets?

[Dovecot] locking questions
by Stewart Dean 11 May '07

11 May '07

I have Dovecot 1.0 in trial use by the IT staff, and have some locking questions Background, the mail server runs procmail, sendmail and NFS exports the user homedir and mailbox to a) a login shell host and b) a mailing list services host. It runs UWIMAP on the usual ports and dovecot on a arbitrary port number. Because of concern with NFS and file access contention. I have the following dovecot.conf file access parms set: a) mbox_dirty_syncs = no b) mbox_lazy_writes = no 1) I am seeing these errmsgs. Are they anything I should be concerned about, or are they just the inevitable result of lock contention for mailboxes and folders by procmail, imap/dovecot and NFS? > In syslog, I am seeing this: > > Apr 23 18:46:34 mercury mail:err|error dovecot: IMAP(sdean): stat(/var/spool/mail/sdean.lock) failed: No such file or directory > Apr 23 18:46:34 mercury mail:err|error dovecot: IMAP(sdean): file_lock_dotlock() failed with mbox file /var/spool/mail/sdean: No such file or directory > > While in maillog: > > Apr 23 18:46:34 mercury mail:err|error dovecot: IMAP(sdean): stat(/var/spool/mail/sdean.lock) failed: No such file or directory > Apr 23 18:46:34 mercury mail:err|error dovecot: IMAP(sdean): file_lock_dotlock() failed with mbox file /var/spool/mail/sdean: No such file or directory 2) I earlier asked, but don't think I got an answer to this question: > Everybody wants to lock differently > 1) procmail (delivering for sendmail), which seems to want to use > dotlocking, fcntl and lockf locking; for whatever reasons, the compile > time tests seem to disallow flock. > 2) UWIMAP which according to wiki.dovecot.org/Migration/UW uses: > mbox_read_locks = flock > mbox_write_locks = dotlock flock > 3) I want to run dovecot in the same environment as I switch over, for > which the locking strategy is supposed to be (according to > http://wiki.dovecot.org/MboxLocking) > mbox_read_locks = fcntl > mbox_write_locks = dotlock fcntl > > Since that same page in the wiki says.

How long before that happens? Is the interval configurable? Thanks to all. A brother sysadmin was stunned by performance gained in Dovecot. He has to keep postmaster messages for a period and filters them into a separate folder...over a long weekend this folder could get to 1500 messages and 150MB...with UWIMAP he could only delete approx 800 at a time and then had to wait 5-10 minutes for it to process. With dc, he marked off the whole folder and it was gone in seconds. -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] Dovecot and Outlook - IMAP Timeout error
by Phillip T. George 11 May '07

11 May '07

Hey guys, I'm having a problem with Dovecot and Outlook. I'm testing with Outlook XP (2002), but the problem occurs with Outlook 2003 as well. I'm using Dovecot 1.0.rc28. The specific error generated (for IMAP) is: "A connection to the server could not be established. <servername> is now in offline mode." In the details: "There may be a server or network problems or your timeout interval may be too short. Protocol: IMAP Server: <servername> Port: 143" It is set up with a POP3 account and an IMAP account within Outlook -- using the same physical email account. The IMAP portion is only used for spam / ham submission, while the POP3 is used for downloading the actual email. The account on the server being used is named "me2.pg.east.eacsd.com" I have a single IMAP account set up in Thunderbird, which is using the account name "me.pg.east.eacsd.com". All mail that is received at "me.pg.east.eacsd.com" is forwarded to "me2.pg.east.eacsd.com" to generate some traffic. Here is the snippet of the mail log which involves me2.pg.east.eacsd.com ( | grep me2.pg.east.eacsd.com | grep -i imap): Apr 25 02:40:11 east dovecot: imap-login: Login: user=<me2.pg.east.eacsd.com>, method=PLAIN, rip=68.14.165.23, lip=64.22.71.38 Apr 25 02:40:13 east dovecot: IMAP(me2.pg.east.eacsd.com): Disconnected in IDLE Apr 25 02:41:10 east dovecot: IMAP(me2.pg.east.eacsd.com): Disconnected: Logged out Apr 25 02:45:41 east dovecot: imap-login: Login: user=<me2.pg.east.eacsd.com>, method=PLAIN, rip=68.14.165.23, lip=64.22.71.38 Apr 25 02:45:41 east dovecot: imap-login: Login: user=<me2.pg.east.eacsd.com>, method=PLAIN, rip=68.14.165.23, lip=64.22.71.38 Apr 25 02:46:18 east dovecot: IMAP(me2.pg.east.eacsd.com): Disconnected Apr 25 02:46:18 east dovecot: IMAP(me2.pg.east.eacsd.com): Disconnected Apr 25 02:50:49 east dovecot: imap-login: Login: user=<me2.pg.east.eacsd.com>, method=PLAIN, rip=68.14.165.23, lip=64.22.71.38 Apr 25 02:50:50 east dovecot: imap-login: Login: user=<me2.pg.east.eacsd.com>, method=PLAIN, rip=68.14.165.23, lip=64.22.71.38 Apr 25 02:51:27 east dovecot: IMAP(me2.pg.east.eacsd.com): Disconnected Apr 25 02:51:27 east dovecot: IMAP(me2.pg.east.eacsd.com): Disconnected Apr 25 02:55:58 east dovecot: imap-login: Login: user=<me2.pg.east.eacsd.com>, method=PLAIN, rip=68.14.165.23, lip=64.22.71.38 Apr 25 02:55:58 east dovecot: imap-login: Login: user=<me2.pg.east.eacsd.com>, method=PLAIN, rip=68.14.165.23, lip=64.22.71.38 Apr 25 02:56:56 east dovecot: IMAP(me2.pg.east.eacsd.com): Disconnected Apr 25 02:56:56 east dovecot: IMAP(me2.pg.east.eacsd.com): Disconnected Apr 25 03:01:27 east dovecot: imap-login: Login: user=<me2.pg.east.eacsd.com>, method=PLAIN, rip=68.14.165.23, lip=64.22.71.38 Apr 25 03:01:27 east dovecot: imap-login: Login: user=<me2.pg.east.eacsd.com>, method=PLAIN, rip=68.14.165.23, lip=64.22.71.38 Apr 25 03:01:58 east dovecot: IMAP(me2.pg.east.eacsd.com): Disconnected Apr 25 03:01:58 east dovecot: IMAP(me2.pg.east.eacsd.com): Disconnected There's more before that, but I'd figured that would be enough: Apr 24 17:18:05 east dovecot: IMAP(me.pg.east.eacsd.com): Disconnected in IDLE Apr 24 17:19:34 east dovecot: IMAP(me.pg.east.eacsd.com): Disconnected in IDLE Apr 24 17:19:42 east dovecot: IMAP(me.pg.east.eacsd.com): Disconnected in IDLE Apr 24 17:20:27 east dovecot: IMAP(me.pg.east.eacsd.com): Disconnected in IDLE Apr 24 17:20:42 east dovecot: imap-login: Login: user=<me.pg.east.eacsd.com>, method=PLAIN, rip=68.14.165.23, lip=64.22.71.38, TLS Apr 24 17:43:18 east dovecot: imap-login: Login: user=<me.pg.east.eacsd.com>, method=PLAIN, rip=68.14.165.23, lip=64.22.71.38, TLS As you can see from the logs, Thunderbird didn't have a problem, which eliminates the possibility of a bad net connection (I'd assume...but I could be wrong). The problem occurred at 3AM. Some people during the day can get it every hour or so. I was able to get it to occur twice (the first time is not shown in these logs). My questions. . . 1. Is there any way to fix this Outlook problem? I have all of the outlook workarounds enabled (along with some for Netscape): imap_client_workarounds = delay-newmail outlook-idle netscape-eoh pop3_client_workarounds = outlook-no-nuls oe-ns-eoh 2. Should Outlook really be connecting and disconnecting that often? 3. Could the problem be occurring because of POP3 and IMAP being used by the same account, and the quick downloading of email via POP3 is eliminating the email for IMAP, thereby causing inactivity in IMAP? Is there a workaround or a known Outlook settings to fix this? Thanks, Phillip

[Dovecot] Troubleshooting - another suggestion...
by Charles Marcus 11 May '07

11 May '07

Hi Timo, I'm the one who suggested the '-n' option to capture the actual config settings that the running dovecot process was using (ala postfix), and you implemented it very quickly - so thanks for that! Now, I'd like to suggest an enhancement... Many people still do not provide basic things like dovecot version, and there are secondary config files like dovecot-ldap, whose settings are not included in the dovecot -n output. How difficult would it be to add these to the output so that the output would include the running dovecot version, as well as any extra config settings from any other files that are loaded when dovecot starts? It would sure make it easier, both for us troubleshooting on our own, and when asking for help on the list. Many thanks, and terrific job on 1.0! Now all dovecot lacks is full support for IMAP ACLs/shared folders, and support for single-instance storage, and it will have no real competition... -- Best regards, Charles

[Dovecot] maildir file name flags out of order?
by Aaron Solochek 11 May '07

11 May '07

I was trying to figure out why my false-positive spam messages were being tagged as "personal" by thunderbird, and I noticed a possible problem. According to DJB: http://cr.yp.to/proto/maildir.html > New flags may be defined later. Flags must be stored in ASCII order: e.g., "2,FRS". Looking at my maildir, I am seeing flags out of order, such as "2,Sdae" Shouldn't that be "2,Sade"? -Aaron

[Dovecot] read only maildir
by Nagyon Almos 11 May '07

Hello All, I try to set up a read only maildir just as in the wiki, to no avail. The extra (public) namespace shows up but I can not susbscribe to it (in thunderbird) or if I change to that "directory" (in mutt), it is empty. Is it the problem mentioned in the wiki (SharedMailboxes#Subscriptions)? If yes, how can I see/use a folder which is not subscribeable? Any help would be greatly appreciated.

[Dovecot] Error: Master request X not found
by Jordi Moles 11 May '07

11 May '07

*Hi, I've been getting the following error from time to time since i started to use dovecot more than one year ago: dovecot: May 07 19:57:24 Error: auth(default): Master request 88729.43523 not found I haven't stopped upgrading dovecot with the hope that this would be a bug and would be fixed some day, but with v1.0.0, i keep getting the same error. It just happens from time to time. Some of the users of my system complain about not being able to get to see their mails, and it is always at the time when this error is logged. Surfing through many forums, i came across with a cause that many people point to: "client closed connection at the exact same time master was logging it in" i don't know if this is what happens to my system, to be honest, i don't have a clue how to check that, i just would like to know if somebody has come up with a solution for this problem, as it seems many people are still trying to face it. thank you. ***

[Dovecot] Sieve plugin

The Sieve plugin page of Wiki documentation (http://wiki.dovecot.org/LDA/Sieve?highlight=%28filter%29) says: "It's also not a good idea to build the plugin against self-compiled Dovecot sources, but then actually use a prebuilt binary package of Dovecot."

[Dovecot] ownership/perms on DC file objects
by Stewart Dean 10 May '07

Back in late March I asked what ownership and permissions Dovecot's own directories and files should have; I have an obsessive nature, and wanted to get things right :(.. On April Fool's Day :), Timo responded: > Dovecot opens pretty much all the configuration etc. files as root > before dropping the privileges. So in general they could all be 0600 > owned by root In my typical turtle-crawl fashion, I got around to today, but the onership/perms came out somewhat differently, which I put down here for anyone that wants to know.........

Actually, the thing we care about is the dspam signature which is unique. So that's not a problem. The point is that you have to (a) when no files exist: move into spam: create a file <sig> with contents "spam" move out of spam: create a file <sig> with contents "notspam" (b) when <sig> file exists with contents "spam": move into spam: shouldn't happen move out of spam: unlink file (c) when <sig> file exists with contents "notspam": move into spam: unlink file move out of spam: shouldn't happen the cron job would have to iterate through all these files and call dspam depending on the contents of the file. And then it all has to be atomic. It's not really all that complex, but I was too lazy to implement it. johannes

[Dovecot] Duplicate emails with several clients
by Erick Perez 10 May '07

10 May '07

Hi, I'm using Centos 4.4 (which is redhat linux but free) that comes with dovecot-0.99.11-4.EL4. I have done a clean reinstall of the server and I have users reporting that everytime they hit "send/receive" in their outlook or outlook express software, they get the same messages, as well as the new ones, over and over again. I use postfix + dovecot and only the pop3 protocol. My dovecot.conf has the following relevant entries default_mail_env = mbox:~/mail/:INBOX=/var/mail/%u client_workarounds = oe6-fetch-no-newmail outlook-idle outlook-pop3-no-nuls mbox_locks = fcntl everything else is at default value. Also, we do not upgrade dovecot because it is not part of the upstream provider, and we do not want to break binary compatibility updates. Thanks for your guidance. -- ------------------------------------------------------------ Erick Perez Panama Sistemas Integradores de Telefonia IP y Soluciones Para Centros de Datos Panama, Republica de Panama Cel Panama. +(507) 6694-4780 ------------------------------------------------------------

[Dovecot] Managesieve: first steps
by Joseba Torre 10 May '07

10 May '07

Hi, I'm trying to get managesieve to work but, as usual, I have some issues... - First of all, the compilation process after applying the patch is a bit strange. I've used this way (i'm using centOS 4 for this pre-tests): $ tar zxvf dovecot-1.0.0.tar.gz $ cd dovecot-1.0.0 $ gzip -cd ../dovecot-1.0.rc28-MANAGESIEVE-v4.diff.gz | patch -p1 $ autoreconf (This ends with an error about missing ./ylwrap) $ automake --add-missing (This copies ylwrap to ., but fails if executed before autoreconf) $ autoreconf $ ./configure && make && sudo make install but I'm quite sure that should exist a better way... - After this, adding protocols = imap imaps pop3 pop3s managesieve and protocol managesieve { listen = *:2000 login_executable = /usr/local/libexec/dovecot/managesieve-login mail_executable = /usr/local/libexec/dovecot/managesieve } to dovecot.conf, everything seems to work fine (pop3 and imap work as usual, and I can connect to the managesieve port), but dovecot -n gives no output. (If I put out managesieve from the protocols, dovecot -n gives the normal output again). (This output is appended at the end) - Finally, I'm using Plain as the authentication mechanism, and I've been unable to connect using kmail or the sieve extension for thunderbird. As I'm not sure if any of these really work, I'll setup horde for further testing. Is there anything that I should be aware of? dovecot -n output: # /usr/local/etc/dovecot.conf syslog_facility: local1 protocols: imap imaps pop3 pop3s listen(default): *:143 listen(imap): *:143 listen(pop3): *:110 ssl_listen(default): *:993 ssl_listen(imap): *:993 ssl_listen(pop3): *:995 ssl_cert_file: /usr/share/ssl/certs/dovecot-beta.pem ssl_key_file: /usr/share/ssl/certs/dovecot-beta.pem login_dir: /usr/local/var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login mail_location: maildir:~/Maildir:INDEX=/var/dovecot/%u:CONTROL=/var/dovecot/%u mmap_disable: yes mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %v.%u auth default: master_user_separator: * passdb: driver: passwd-file args: /usr/local/etc/dovecot-master.conf master: yes passdb: driver: pam args: blocking=yes userdb: driver: passwd args: blocking=yes socket: type: listen client: master: path: /var/run/dovecot/auth-master plugin: quota: fs Thanks. -- Joseba Torre.

[Dovecot] Dovecot and horde issues
by John H. Bennett III 10 May '07

10 May '07

Hello, First time poster to this list, please be kind. I am having difficulties trying to get the current stable version of horde's imp webmail to work correctly using dovecot 1.0rc15. I am using a pre-release version of SME Server 8 which runs on top of CentOS 5. I have also tried using the 1.0 release of dovecot as well. What is happenning is that when I login to imp, I don't see any folders. I can create folders in imp which do get created in my Maildir directory, but I can't see them. If I revert back to dovecot-0.99.14-1.2, then I am able to see my folders. I have been looking in the wiki at the steps needed to upgrade from 0.99 to 1.0 and I thought everything had been taken care of, but since things aren't working, I have overlooked something. I also browsed the archives and see that others are using horde with various dovecot 1.x releases, so I know it should be possible to get it to work. My dovecot.conf currently only as the below, which works fine for 0.99: maildir_copy_with_hardlinks = no my /etc/pam.d/dovecot has: more /etc/pam.d/dovecot #%PAM-1.0 auth required pam_nologin.so auth include system-auth account include system-auth session include system-auth imp servers.php: $servers['_prompt'] = array( 'name' => 'Choose a mail server:' ); $servers['thebennetthome2.com'] = array( 'name' => 'IMAP Server', 'server' => 'localhost', 'protocol' => 'imap/notls', 'port' => '143', 'maildomain' => 'test.com', 'smtphost' => 'localhost', 'realm' => 'test.com', 'preferred' => '' ); php -v PHP 5.1.6 (cli) (built: Apr 9 2007 03:37:21) Copyright (c) 1997-2006 The PHP Group Zend Engine v2.1.0, Copyright (c) 1998-2006 Zend Technologies I do get some php errors when logging into horde, and a lot of php errors when creating folders that I can post if needed. I did post my issue to the horde list as well, but there has been no answer to date. Please let me know what other information is needed to assist me with fixing this issue. Thank you very much, John Bennett Thanks, John H. Bennett III bennettj(a)johnbennettservices.com

[Dovecot] Email client dowloads previously read messages as new during migration.
by Eric and Barbara Sammons 09 May '07

09 May '07

I am migrating from UW to dovecot and using mbox. I have been able to find mbox to maildir migration information and tools; however, I have had little luck finding any tool or information for performing such a migration where I wish to keep mbox. ( I know I should migrate to MailDir, but in the case I wish to take baby steps.) I have setup dovecot pop3 communication and I go to my email client and everything works fine with the exception that all mail I have previously read (when using UW as my POP server) is downloaded again as NEW. Is there a way to prevent this from happening without setting my client to delete mail from server? thank you!

[Dovecot] Troubleshooting enhancement request...
by Charles Marcus 09 May '07

09 May '07

Hi Timo, You were good enough to add the -n flag to the dovecot command to output the current *changed* config parameters (changed as compared to the defaults) of the running dovecot process. This makes it much easier to troubleshoot issues - thanks! Another flag that postfix has is the -d flag (postconf -d). This one outputs all of the DEFAULTS of the current running postfix process/version. I just used this today to compare what I had in my main.cf to what the defaults were - and for some reason I had uncommented a bunch of things that didn't need to be uncommented (because they were the default setting), resulting in a much larger output from the postconf -n command. I know its not a big deal, but any chance of implementing this for dovecot? This would make it easy to keep the conf file (and the -n output) clean and neat. Many, many thanks for 1.0.0! -- Best regards, Charles

[Dovecot] Trying to modify the source - fopen problems
by Phillip T. George 09 May '07

09 May '07

Hello all, I don't know if this needs to be sent to a different list or not, if so, please let me know. Anyways, I'm trying to modify the dovecot source a bit, but the problem I'm having is that whenever I use "fopen", it always returns NULL. I've tried a variety of things, even fopen("/dev/null", "w") -- because that should almost always work. I'm trying to get it to work in src/pop3-login/client-authenticate.c Any idea why this might be happening? Any suggestions as to where to put the code instead? (I'm trying to check the username against some information in a file OR pass the username to a process and have it do the work) Thanks, Phillip

[Dovecot] Inconsistent Mailbox with Eudora as POP3 client
by Amon Ott 09 May '07

09 May '07

Hello everyone, one of our customers using QUALCOMM Windows Eudora Version 7.1.0.9 as POP3 client with Dovecot 1.0.0 under Linux using Maildirs reports that on various accounts they get occasional "inconsistent mailbox" errors at quit. The same Docevot binary in the same environment on other servers works fine for several other customers and ourselves. We use Postfix 2.2 with Dovecot deliver and Sieve plugin, nothing else touches the Maildirs. I have no idea what goes wrong there, I already suspected memory corruptions. The system is low on memory and uses some swap (more memory soon), does that trigger such problems? The Eudora log shows: <Dominant>, Shutting down POP connection, QUIT [08:54:07 AM] There has been an error transferring your mail. I said: QUIT and then the POP3 server (xyz(a)my.domain.de) said: ERR Mailbox is in inconsistent state, please relogin.

[Dovecot] Hot to get rid of \"DON\'T DELETE THIS MESSAGE\" messages?
by foxx＠freemail.gr 09 May '07

09 May '07

I'm using Dovecot 1.0.0 (mbox) with Postfix 2.4 on my FreeBSD box, as a pop3-only server (imap is disabled). All account mailboxes are accessed using Outlook clients. I've noticed that, whenever I'm retrieving mail with pop3, a "DON'T DELETE THIS MESSAGE" is created in mbox. Although these messages are never sent to client MUAs, I found them very annoying. BTW I don't use (or used before) UW or Pine or any other c-client, therefore I assume it's a Dovecot issue. Previously I was using Cyrus and never had such a problem. Any idea how this can be fixed?

[Dovecot] sporadic slow/non response, problems copying to sent folder
by Danno Coppock 09 May '07

09 May '07

After experiencing these symptoms through many of the release candidates, we've been at v1.0.0 now for a few weeks, and they're still there. Perhaps a config issue with my setup (mbox locks?). It's really too disrupting to continue using this way. I've included symptoms, client info, mta info, log entries and config file. What other information can I provide? Please advise.

[Dovecot] .imap files
by L. Scott Loftin 09 May '07

09 May '07

Dovecot version: 1.0.rc7 OS: Red Hat Fedora Core 6 CPU: x86 Filesystem: Linux I have recently upgraded from Fedora Core 4 to Fedora Core 6 (the FC6 was a clean install, not an upgrade). Prior to the upgrade, I used Dovecot to handle IMAP email that talked to Outlook clients. After the FC6 install and copying the .imap* files to the newly recreated user accounts, Outlook is not seeing the old email. Dovecot is creating new dovecot.* files to hold new email, not looking in the existing .imap.* files. Is there a way to either convert the .imap* files into the new dovecot.* files or any way to recover the email that anyone knows about? Thanks! Scott

[Dovecot] Switching from mailbox to maildir.. duplicates!
by Lars Johansen 09 May '07

09 May '07

Hi We have been running a dovecot server for some time.. users connect with pop. Now this server is going to be substituted with a new one.. before we used mbox, but now we will move to maildir! I have done some testing transfering the mail with the mb2md script, the conversion works correctly, but users gets duplicates since they selected "keep mail on server" I have googled for the problem, and set pop3_reuse_xuidl=yes and pop3_uidl_format = %08Xu%08Xv is the same on both servers.. but no luck. My first tought was to script in an X-UIDL header for each mail that was converted.. but that wont work since the mail already downloaded by the client didnt contain that header.. is there anyone that has some experience with this, or knows if its possible? Many Greetings, Lars Johansen

[Dovecot] Strange Mail Problem
by Jason Baker 09 May '07

09 May '07

I submitted this question to the Postfix maillist and they suggested that I post to this one. Here's my issue: I have a Postifx email system running on a CentOS 4 box, with Dovecot pop3 and imap. Last week, one of my users reported to me that about a dozen emails suddenly showed up in his in box (as unread messages), but none of them were addressed to him. Under further investigation, they turned out to be from another user's inbox. The messages were all over a month old. How could mail simply show up in one inbox from another user's? We're using Mozilla Thunderbird 1.5. Anyone else run into issues like this? -- *Jason Baker */IT Coordinator/ *Glastender Inc.* 5400 North Michigan Road Saginaw, Michigan 48604 USA 800.748.0423 Phone: 989.752.4275 ext. 228 Fax: 989.752.4444 www.glastender.com <http://www.glastender.com> -----BEGIN GEEK CODE BLOCK----- Version: 3.1 GIT$ d- s: a C++$ LU+++$ P+ L++>L++++ !E--- W+++ N o?

[Dovecot] File Changes and IDLE
by Andy Shellam 09 May '07

09 May '07

Hi Timo and all, I used to use Dovecot back in the 0.99 days a couple of years ago, had since moved to Courier IMAP, but with the release of Dovecot 1.0.0, I'm looking at moving back! One thing I currently have set up and working with Courier is the use of the enhanced IDLE mode, whereby Courier uses FAM (File Alteration Monitor) to monitor changes in the INBOX, and sends the details to the client as soon as a new mail arrives. Is this something that Dovecot supports? If possible, I'd prefer not to use FAM, as it crashes at random intervals and I have to keep restarting it. When I configured Dovecot, it said "File change notification method ..... : none". Does this mean FreeBSD doesn't support any method of notifying of file changes? Is there any way I can install, or re-configure the kernel, to include this support? Thanks, Andy

With the mail -f command I can read messages and with POP3 protocol and Thunderbird also. Install : dovecot-0.99.11-4.EL4 :-( What can I do ? Thanks Sophie

[Dovecot] Password Problems
by Don O'Neil 09 May '07

09 May '07

I have a user that has a password that has {} in it (left and right curly brackets). Under earlier versions of dovecot (less than v1) there weren't any problems with it. Now that we've upgraded to v1, his password no longer work. The short term solution is for him to change his password, which he has. Has anyone else seen this same problem? It seems to pop up more when using webmail apps such as Squirrelmail or Uebiumaiu. Thanks!

[Dovecot] troubleshooting new dovecot installation

Hello, I'm setting up a new mail server using freebsd 6.2, postfix, dovecot with SASL and, eventually, squirrelmail. I've gone through http://wiki.dovecot.org/TestPop3Installation the program is running, plain works over telnet from local host or from a remote machine.

Re: [Dovecot] What would you tell the CIO in an "ABCs of Email" overview?
by Kenneth Porter 08 May '07

08 May '07

Perhaps the first fundamental is that Internet email isn't handled by one kind of server. It's a suite of protocols that are served by distinct processes. At minimum, you have inbound (POP3, IMAP) and outbound (SMTP) servers. You may also have a separate authentication server (LDAP) and perhaps other pieces providing calendaring, web mail (HTTP), and central storage of client configuration (ACAP). The different protocols exist not because some programmer thought it would be cool to create a new protocol, but because they serve completely different needs. For example, POP3 was designed to support lightweight disconnected clients. IMAP provides server-based storage of mail folders. LDAP provides authentication not just for mail systems but for many other applications. (I'm sure experts for each of these protocols could provide better explanations. The RFC for each probably has a motivation section that you can quote.) An important "slide" in the presentation would show the plumbing that ties all these protocols and processes together and shows how mail moves through the system. In some cases the plumbing itself is variable. For example, spam and virus processing might occur within several servers or within a client.

[Dovecot] sieve parse error

Hello everyone, I'm using Dovecot (v1.0.beta3-3ubuntu5.4 under Ubuntu) with postfix and LDA with virtual users. Everything is working fine. To filter mails I use the Dovecot Sieve feature. But I get some strange error for one simple Sieve script: ---------------------------------------------------------------------------------------------------- require "fileinto"; if header :contains ["to", "Cc", "Bcc"] ["freewrt-users(a)freewrt.org"] { fileinto "Mailinglists.FreeWRT"; stop; } elseif header :contains ["to", "Cc", "Bcc"] ["getmail(a)discworld.dnsalias.org"] { fileinto "Mailinglists.getmail"; stop; } ---------------------------------------------------------------------------------------------------- This is the error I get in mail.log: ---------------------------------------------------------------------------------------------------- May 6 15:47:08 gehirnschnecke deliver: sieve parse error for matthias(a)adminlife.net: line 8: syntax error, unexpected IF, expecting '{' ---------------------------------------------------------------------------------------------------- After studying sieve.info my sieve script should be correct. What could be wrong here? Thanks & best regards Matthias

This kind of behavior looks like a network issue. > You called it. We access the server over the Internet. How did I forget to provide that small detail? However, that's not the slowness I speak of. Perhaps a better term is long delay, like waiting on some timeout, before message loadding (in symptom 1., above). So are there parameters to tune, that will make dovecot behave nicer? I do not believe this to be connectivity outages between our clients and the server. For one, we never experienced these symptoms with UW-IMAP. I just duplicated the stall on copying to Sent folder. This is probably the more prevalent, and annoying of the two problems. facts: * There was only one active client. * The client was T'bird, v1.5.0.10, running on XP. * This particular test had a 3Mb attachment. * The mail was delivered immediately to the single, remote recipient (after a ~20 seconds of 3Mb upload). * The "Copying to Sent Folder" dialog stayed up for (no exaggeration) 15-minutes, and then completed; the message is in the Sent folder now. suspicion, from months of experiencing the behavior: * Attachments are usually involved. How does the config look? Are the mbox lock settings appropriate? I was somewhat shooting in the dark there. * Sendmail 8.13.6/8.13.6 * $sudo sendmail -bt -d0.10 < /dev/null | grep HASFLOCK OS Defines: BSD4_4_SOCKADDR HASFCHOWN HASFCHMOD HASFLOCK mbox_read_locks = flock mbox_write_locks = flock What else can I provide? netstats? tcpdumps? Are there logs/debugging appropriate to enable? Thanks for any ideas, Danno

[Dovecot] Converting Courier mailboxes to Dovecot
by Andy Shellam 05 May '07

05 May '07

Hi, I have around 100 mailboxes (maildirs) to convert from Courier IMAP (4.1.3) to Dovecot. (From a recent backup) I've tested a few mailboxes on Dovecot 1.0.0, and while the client doesn't notice any difference (at least in Thunderbird) I'm hoping to get rid of the old Courier folders and convert any useful information they may have into Dovecot. I've tried Timo's migration script (http://www.dovecot.org/tools/courier-dovecot-migrate.pl) but it fails at line 230 with a "no file/directory" error. At that line, it appears to be finding Courier's keywords folder (courierimapkeywords), and looking for a file called ":list". However in my mailboxes, there's no file by that name, only what looks like a set of standard IMAP filenames, most of which are empty files. If I can't salvage anything useful, is there any adverse effects to me deleting all the "courier*" files/folders from each mailbox and subfolders so when the client connects back when Dovecot's running, it creates it's own UIDs and keywords etc? Thanks Andy.

[Dovecot] Help with LDAP authentication - user / user+domain
by Venilton Junior 04 May '07

04 May '07

Hello Folks, I've my dovecot working well and authenticating in my ldap servers. But I'd like configure my users to authenticate in two ways. One is just submitting the username and the other one is providing user(a)domain.com . I'm moving from a cyrus-imap solution to dovecot and I've implemented it with VD domains. But nowadays I still have one domain at my servers. So to no cause to much impact to users, I'd like to provide this two ways of authentication. Here follows my dovecot-ldap.conf: hosts = localhost dn = uid=admin,ou=administrators,ou=topologymanagement,o=netscaperoot dnpass = XXXXXX auth_bind = no ldap_version = 3 base = dc=domain,dc=com deref = never scope = subtree user_attrs = mail,homeDirectory,,,,quota=quota=maildir:storage user_filter = (&(objectClass=VirtualMailAccount)(mail=%u)(accountActive=TRUE)(delete=F ALSE)) pass_attrs = mail,userPassword pass_filter = (&(objectClass=VirtualMailAccount)(mail=%u)(accountActive=TRUE)(delete=F ALSE)) default_pass_scheme = SSHA user_global_uid = 100 user_global_gid = 101 My logs: Apr 30 13:47:58 server dovecot: auth(default_with_listener): client in: AUTH 1 PLAIN service=POP3 lip=xxx.xxx.xx.xx rip=xxx.xx.xxx.xxx resp=AGpveWNlLm1hcmlhbm8AbWFrdHVi Apr 30 13:47:58 server dovecot: auth(default_with_listener): ldap(user.test,xxx.xx.xxx.xxx): pass search: base=dc=domain,dc=com scope=subtree filter=(&(objectClass=VirtualMailAccount)(mail=user.test)(accountActive= TRUE)(delete=FALSE)) fields=mail,userPassword Apr 30 13:47:58 server dovecot: auth(default_with_listener): ldap(user.test,xxx.xx.xxx.xxx): unknown user Apr 30 13:47:59 server dovecot: auth(default_with_listener): client out: FAIL 1 user=user.test Apr 30 13:48:05 server dovecot: pop3-login: Aborted login: user=<user.test>, method=PLAIN, rip=xxx.xx.xxx.xxx, lip=xxx.xxx.xx.xx If I provide user.test(a)domain.com works fine.

[Dovecot] Sieve not recognizing keywords
by Alexander Hoogerhuis 04 May '07

04 May '07

First, I've been lurking and using dovecot for a few years now and I've always liked it, great piece of software! :) I've finally decided to clean up my act here and get virutal users and get postfix (2.3), dovecot (1.0.0) and deliver to play nice, using postfixadmin. I have it 99% there, but one thing is left: When I receive mails, deliver finds my virtual home dir and then tries to compile the sieve script (converted from procmail with the script mentioned in the wiki), and then always bums out on this: sieve parse error: line 3: Unsupported features in require line and line 3 looks like this: require ["fileinto","regex","envelope","vacation"]; which should be fine? Then I googled around and found this thread from january: http://www.dovecot.org/list/dovecot/2007-January/018376.html Which made it sound like the sieve plugin 1.0.0 had a bug that got fixed in 1.0.1. I am doing all of this on Gentoo, so I decided to just redo the ebuild so that I got the dovecot 1.0.0 ebuild, but with the sieve plugin 1.0.1. Aparently I get the same error and now am at a loss here. Any pointers? -A

[Dovecot] Testing IMAP clients with Dovecot, problems with MacMail
by Stewart Dean 04 May '07

04 May '07

I've been testing my user community's IMAP clients when I try to login and then transfer a big message from the inbox into a folder in an overquota folder directory. I am using native filesystem quotaing in AIXV5.3 with UWIMAP and comparing my results with what I see with Dovecot 1.0.0. (My Dovecot built without any plugins or quota extensions) Everything matches/works except for Mac Mail under SSL with Dovecot.. Mac Mail: 1) with UWIMAP, login and mailbox load goes OK, then the illegal overquota xfer fails (as it should) with a popup reading 'Message could not be moved', with (port 993) and without (port 143) SSL 2) with Dovecot, 1) login and mailbox load goes OK to port 10143, plain listen, and the illegal xfer correctly fails as it should with a popup messge under a plain connection, but 2) When the port number is set to the Dovecot ssl_listen port and the SSL box is checked, Mac Mail doesn't bring up the inbox and folders...it acts like it can't connect. Has anyone else seen this behavior, and is there a fix? Mac Mail is also known as Mail.app. I am testing it at 1.3.11 and 2.1.1. In the July '05 archive, I found this: > It looks like Mail.app treats "non-standard" ports differently. On the > standard port (993), the "SSL" option seems to do pure SSL; but with > another > port specified, it does clean-plus-starttls (and hence fails horribly, > because > it's talking to a pure SSl service) Is there anything I can do to get MacMail to behave correctly? Or will it clear up when I shut down UWIMAP and give Dovecot the default ports. A Bronx cheer for Mac Mail........ My thanks in advance, S. Everything else I tested behaves...for anyone that's interested....... ================ Over Quota Xfer results ==================== Insecure Pine from Unix login shell: refused by both UWIMAP (cannot exceed user or group quota) and Dovecot (there's not enough disk space.) server apps. It is presumed that this will be used from within an SSH session to secure the transmission. Webmail (horde, insecure and secure) : refused by both UWIMAP (cannot exceed user or group quota) and Dovecot (there's not enough disk space.) server apps. PC: TBird 1.5, 2.0, Sea Monkey and Netscape 7.2: get a popup with both UWIMAP (cannot exceed user or group quota) and Dovecot (there's not enough disk space.) server apps, both secure and insecure Mac: Seamonkey: ditto, same as PC Sea Monkey Mac Mail or Mail.app only works insecure, as per above

[Dovecot] Does dovecot do any address checking or referring back to a server?
by Wade Smart 04 May '07

04 May '07

This is a dovecot question so bear with me. I just upgraded to Ubuntu 7.04 from 6.06. I used fetchmail and postfix but not dovecot on 6.06. Fetchmail retrieved my mail and postfix put it in my maildir. I used Evolution to access the maildir directly. I setup Evolution to send mail directly as well. With this move I decided to go the extra step and get dovecot working. With some help on this form, I did that. But, I immediately started having trouble with getting my mail. Fetchmail is retrieving it but postfix keeps not processing for some reason. Im geting these error message: May 2 17:14:11 wadesmart postfix/qmgr[14778]: 6D4AD14286F3: to=<wadesmart(a)mail.wadesmart.com>, orig_to=<wade@localhost>, relay=none, delay=9331, delays=9307/25/0/0, dsn=4.4.1, status=deferred (delivery temporarily suspended: connect to smtpout.secureserver.net[64.202.165.58]: Connection timed out) The thing is - Im not sending mail at all through postfix. So my question is, I know that dovecot only serves up email to a mail client but, does it do something that I have totally missed that would some how or some way refer mail back to a server? Is there some type of address check or something going on? I know Im grasping at straws here but, I have been unable to get help from the postfix list or any list for that matter so if I can eliminate one more piece of the puzzle, all the better. Thanks.

[Dovecot] Dovecot SASL for postfix: Client host rejected: when relaying using POP mail client
by Nad 03 May '07

03 May '07

Hi everyone I have setup an ISP style mail system using postfix, dovecot, squirrelmail and mysql on ubuntu server 7.04. Everything seems to be working fine with sending recieving emails but relaying on submission service (port 587).

[Dovecot] connecting postfix with dovecot trouble
by André Höpner 03 May '07

03 May '07

Hello listmembers, we have some trouble connecting postfix to dovecot. after a lot of hours the transport and delivery is working but dovecot can't get the correct user. postmap -q some.user(a)domain.com ldap:/etc/postfix/ldap-aliases.cf first returns: someuser The mailbox someuser exists and i can login with this user on imap and i can deliver directly using deliver -d but on mail delivery thrue postfix dovecot is not looking for someuser. It looks for someuser(a)host.domain.com. ---8<------ May 3 16:18:42 mail postfix/pickup[24686]: C94251DB23E: uid=0 from=<root> May 3 16:18:42 mail postfix/cleanup[24769]: C94251DB23E: message-id=<20070503161842.C94251DB23E(a)host.domain.com> May 3 16:18:42 mail postfix/qmgr[24544]: C94251DB23E: from=<root(a)host.domain.com>, size=322, nrcpt=1 (queue active) May 3 16:18:42 mail dovecot: auth(default): master in: USER 1 someuser(a)host.domain.com service=deliver May 3 16:18:42 mail dovecot: auth(default): ldap(someuser(a)host.domain.com): user search: base=dc=domain,dc=com scope=subtree filter=(&(objectClass=posixAccount)(uid=someuser(a)host.domain.com)) fields=mail,homeDirectory May 3 16:18:42 mail dovecot: auth(default): master out: USER 1 someuser(a)host.domain.com home=/var/mail/dovecot/someuser uid=100 gid=12 May 3 16:18:42 mail postfix/pipe[24772]: C94251DB23E: to=<someuser(a)host.domain.com>, orig_to=<some.user(a)domain.com>, relay=dovecot, delay=0.04, delays=0.02/0.01/0/0.02, dsn=2.0.0, status=sent (delivered via dovecot service) May 3 16:18:42 mail postfix/qmgr[24544]: C94251DB23E: removed ---8<------ It seems that postfix or dovecot appends the hostname to the mailboxname. But i cant figure out which of both. If i change the uid to someuser(a)hostname.domain.com on ldap-server anything works fine. how can i fix this? i dont know if anyone needs config files for diagnostic. if so - please tell me and i post the needed informations. best regards Andre Hoepner

[Dovecot] Any plans for storing messages on a database?
by Francisco Reyes 03 May '07

03 May '07

Redudancy and recovering from a mailstore failure is one of the concerns I am trying to address where I work. Any plans to have Dovecot store emails in a database? NAS/SAN devices which do automatic replication to a second device are extremely expensive. I also don't see any distributed filesystem which is mature and available for the OS we use (FreeBSD). I recall at one point, many months back, Timo mentioned that perhaps storing the messages in the database was a possibility for the future. Any additional thoughts on this?

[Dovecot] Migrate from mlbox to maildir, lock problem
by Sylvain Nemtua 02 May '07

02 May '07

Hi We've been using dovecot successufly for few month. Previous setup : solaris 8, postfix+LDA, mbox + index on NFS (Netapp), 2500 accounts Everything shared overs NFS, multiple servers connect to index, mbox. mail_location = mbox:/var/mail/mbox/%u:INBOX=/var/mail/%u:INDEX=/var/mail/indexes_dovecot/%u We had at first some issue with mbox locking, using lock_method = dotlock solve the issue. The problem seemed to be with fcntl. I Migrate to maildir to ease administration to use maildir quota I use mb2md-3.20.pl to migrate the mbox everything works smooth. Actual setup : solaris 8, postfix+LDA, maildir + index + control on NFS (Netapp) I change the mail_location settings to mail_location = maildir:/var/mail/maildir/%u:INDEX=/var/mail/indexes_dovecot/%u:CONTROL=/var/mail/dovecot_control/%u And now I'm facing new locking issue : Errors on user loging, users leaving mail on server downloading the same mail over and over.

[Dovecot] How to use option allow_nets?
by Bernd Kuhls 02 May '07

02 May '07

Hi, according to http://wiki.dovecot.fi/PasswordDatabase/ExtraFields/AllowNets there exists an option allow_nets to restrict IP ranges from where users are allowed to login to Dovecot. I am using Debian Etch with the official Dovecot packages: # dpkg -l | grep dovecot ii dovecot-common 1.0.rc15-2 ii dovecot-imapd 1.0.rc15-2 ii dovecot-pop3d 1.0.rc15-2 using a mostly unchanged dovecot.conf. I tried to add the line allow_nets=127.0.0.0/8,192.168.0.0/16 in the block passdb pam { which is the default enabled auth code in Debian. When starting Dovecot I get this error message: # /etc/init.d/dovecot start Starting mail server: dovecot Error: Error in configuration file /etc/dovecot/dovecot.conf line 777: Unknown setting: allow_nets According to the Dovecot changelog > 2006-02-27 18:46 Timo Sirainen <timo.sirainen(a)movial.fi> > > * src/auth/: auth-request.c, auth-request.h: Added "allow_nets" > extra field. If set, the user can log in only from within the > given networks (hope the code is correct...) the option exists since February 2006, while the Debian package was released in December 2006. What I am doing wrong? Using TCP wrappers instead seems not to be an option according to http://dovecot.org/list/dovecot/2006-April/012476.html Greetings, Bernd Kuhls

[Dovecot] Best authentication option
by Eric 02 May '07

02 May '07

Dear Dovecot experts, I have a small home server debian based, with postfix/dovecot/squirrelmail installed locally and working. Dovecot is used non-secured (no imaps) but only on the 192.168.0.100 address (address of the server on the local network). I want to use squirrelmail to read my email from outside. Squirrelmail can configured to access it in particular, either through cram-md5 or login auths. In that situation, is it better (I mean more secure) to use : 1) auth mechanim = cram-md5 or 2) auth mechanism = plain (using PAM authentication for dovecot) ? That will determine my dovecot configuration. Thank you Eric

[Dovecot] Strange directory created at dovecot launch
by Eric 02 May '07

02 May '07

I installed dovecot from scratch and compiled it from 1.0.0 source. Installed in /usr/local. Now everytime I launch dovecot it creates and uses /usr/local/var/lib/dovecot and /usr/local/var/run/dovecot directories. For the latter I found the modifications to do in dovecot.conf for using /var/run/dovecot instead, but for the former I see nothing about such directory in dovecot.conf. What happens ? How can I configure it so that dovecot uses /var/lib/dovecot instead ? Thank you Eric

[Dovecot] Migrate from dovecot to dovecot.. new server
by Lars Johansen 02 May '07

02 May '07

Hi We have been running a dovecot server for some time.. users connect with pop. Now this server is going to be substituted with a new one.. before we used mbox, but now we will move to maildir! I have done some testing transfering the mail with the mb2md script, the conversion works correctly, but users gets duplicates since they selected "keep mail on server" I have googled for the problem, and set pop3_reuse_xuidl=yes and pop3_uidl_format = %08Xu%08Xv is the same on both servers.. but no luck. My first tought was to script in an X-UIDL header for each mail that was converted.. but that wont work since the mail already downloaded by the client didnt contain that header.. is there anyone that has some experience with this, or knows if its possible? Many Greetings, Lars Johansen

[Dovecot] Courier-imap + dovecot simultaneously?
by Charles Marcus 02 May '07

02 May '07

Hi everyone, I have a client I've been trying to talk into switching from courier to dovecot, but the owner of the company wants me to set up two different accounts in Thunderbird (I finally got him switched to that from outlook express), one accessing his account through courier, and one through dovecot, so he can compare the speed... Is this even possible? I've never tried it before, so before I spend a lot of time, I want to know if I'd be wasting it (my time)... Thanks, -- Best regards, Charles

[Dovecot] PAM, Active Directory, all users mapped to uid=0
by Matt Zukowski 01 May '07

01 May '07

I'm having a problem with authentication using PAM, connected on the back end to Active Directory. PAM authentication itself works fine. We can log in to the machine using AD credentials without any problems. Each user is automatically mapped to uid's in the 10000+ range. However, for some reason when the user logs in via dovecot, the user's uid and gid are showing up as 0. For example: dovecot: May 01 11:22:47 Info: auth(default): master out: USER 3 mzukowski uid=0 gid=0 home=/home/URBACON/mzukowski dovecot: May 01 11:22:47 Error: Logins with UID 0 not permitted (user mzukowski) Is there a reason why dovecot might not be resolving the uid and gid correctly? PAM itself seems to be doing this right, since when I log on to the machine as an AD user, their UID shows up correctly as 10000+. Thanks, Matt. -------------- This e-mail message is privileged, confidential and subject to copyright. Any unauthorized use or disclosure is prohibited.

I have been using uw-imap on my mailserver. I tried briefly to use dovecot with the default config. It seem to work faster, but users imap folders (user accounts are in openldap) disappeared. Is there a sample config somewhere I can look at to get some idea how to configure dovecot so all the imap folders users created will appear when I make the switch? Most of my users login via Horde.

[Dovecot] Doubled subjectlines in mailfolders
by Götz Reinicke 30 Apr '07

30 Apr '07

Hi, after the upgrade from 0.99 to 1.0rc15 on our RHEL 5 Server I noticed, that some of my mailfolders do double the mails subject line in the listview of thunderbird. The mail itself isn't doubled and the second mail contains a different content from a mail that didn't show up in the list. SO it seams, that only the subject line is somehow wrong. Any ideas or tips? I haven't found anything on that googling or in the list archive; but maybe I'm searching with the wrong syntax ... Regards Götz

Ok.

In my Maildir/new I had 884 new messages. The tutorial said to access the Inbox, and I did and could. However, then my 884 messages were gone!!! I do not understand what the heck happened. Did I just loose all my messages?

[Dovecot] dovecot sendmail mysql no inbox error
by jan gestre 29 Apr '07

29 Apr '07

hi guys, we are experiencing this particular problem with one of the webmail server we manage. the server is using dovecot as pop3 and imap server while sendmail is being used as mta. when this user tries to login via telnet, this is what i've got: $ telnet localhost pop3 Trying 127.0.0.1... Connected to localhost.localdomain (127.0.0.1). Escape character is '^]'. +OK dovecot ready. user user1 +OK pass password +OK Logged in. -ERR No INBOX for user. Connection closed by foreign host. when i looked at the maillog i saw this: Apr 25 20:52:32 samplemail pop3(samplemail): File isn't in mbox format: /var/mail/samplemail Apr 25 20:52:32 samplemail pop3(samplemail): File isn't in mbox format: /var/mail/samplemail Apr 25 20:52:32 samplemail pop3(samplemail): Couldn't open INBOX: Internal error occured. Refer to server log for more information. [2007-04-25 20:52:32] tried google but not much of help, they just suggested to update or replace dovecot. i already update dovecot and made some changes to default_mail_env parameter, still the same result. dovecot version is 0.99 on a fedora 4 box any idea?

[Dovecot] Shared mailbox plans
by Timo Sirainen 28 Apr '07

28 Apr '07

** Configuration ** namespace shared { prefix = user/%u/ location = maildir:/home/%u/Maildir:INDEX=~/Maildir/shared-indexes } So the only difference to how it's configured now is that %u is expanded to whatever user whose mailboxes we're accessing. ACL plugin then uses that user as the owner in the namespace's mailbox owner. Since the default ACL is to not give any access to non-owners, the mailboxes without dovecot-acl files will be invisible. If ACL plugin isn't loaded, I suppose the mailboxes can be accessed if the process has filesystem permissions to access them. ** ACL vfile speedups ** Currently it stat() the dovecot-acl file a bit too often. It doesn't do it more than once a second, but there's really no need to do it even that often. I guess it could be changed to be configurable with default being something like 5 minutes. Create a new dovecot-acl-list file which lists all the mailboxes which have dovecot-acl file with "l" right (visible in mailbox list) to any non-owner. It could be in "<timestamp> <mailbox name>" format. This allows other users to quickly get a list of mailboxes that are potentially visible to them. They still need to read the dovecot-acl file from the mailbox before knowing for sure. If the dovecot-acl-list file doesn't exist or if at any time any timestamp doesn't match dovecot-acl file's current mtime, the file is rebuilt by looking into all mailboxes' dovecot-acl files (if the reading user has write permissions to the directory, otherwise it just keeps it in memory). Whenever Dovecot modifies dovecot-acl file, it also updates the dovecot-acl-list file. This means that the file can contain stale data only if a new dovecot-acl file is created without updating dovecot-acl-list file. Even that will be fixed the next time the owner does a LIST (or select the mailbox, or anything that causes its dovecot-acl file to be stated), which causes ACL plugin to notice the desync. There exist also global ACL files. These need to be included in the dovecot-acl-list file as well. The only issue with them is that user doesn't necessarily have a mailbox even though the global ACL file exists. So these need to be marked somehow in the dovecot-acl-list file as non-existing mailboxes. Then if user creates a mailbox with such name, the mark is removed. Deleting the mailbox puts the mark back. After the visible mailbox list has been figured out once, only the dovecot-acl-list file needs to be stat()ed once in a while instead of all the mailboxes' dovecot-acl files. ** User list ** The next problem is how to quickly get a list of users whose mailboxes are visible to ourself so they can be included in mailbox list. I couldn't figure out anything new and great for this, so the options are the same as in http://dovecot.org/list/dovecot/2006- October/017082.html Although for dict backend I could make it a bit more secure. Currently dict has "private" and "shared read-write" options to store the data with. The shared users list could be done with "shared read- only". ** Virtual domains ** ACL plugin could support virtual "group=@domain" to give access to usernames ending with @domain. Or perhaps the group could support wildcards? "group=*@domain"? That way it wouldn't be required to have @ really in the username. Anyway, I think "anyone" should then be aliased to "group=*@domain". If there are multiple virtual domains and you let the users manipulate the ACLs themselves, I'd think they want anyone to mean anyone within my domain (my organization) rather than really anyone who just happens to be using the same server. I think it would also be annoying if anyone could really force their own mailboxes to be visible to a lot of people. That could be used for spamming as well.. If administrator wants to have global mailboxes that really are visible to all domains, they could be done with public namespaces (not shared). ** Quota ** This is kind of problematic. The behavior depends entirely on quota backend: - Filesystem quota of course tracks the quota based on the file's owner - Maildir++ quota counts the quota for the user whose maildir the shared mailbox exists in. This means it also requires filesystem level access to maildirsize file, otherwise the quota updating happens sometimes later when the quota is recalculated. - Dict quota.. I think it'll need a new path for each shared mailbox, which is modifiable by any user. So while your own quota would exist in private/quota/storage, the shared mailboxes' quota would exist in shared/quota/storage. This means that the dict quota needs to be able to know what mailboxes the current user has shared. It also gets a bit tricky to update the quota if mailbox is unshared. The quota could be tracked individually for each mailbox also, but I'm not sure if that's such a great idea either. Perhaps a new quota backend could be implemented to make all this easier. The mail sizes could be tracked in index file, so getting the size of a mailbox could be done simply by reading the value from the index file's header. With mailbox list indexes (in CVS HEAD) they'd all be listed in a single mailbox.list.index file, which would make summing them up really fast. This would require that users don't use private index files for shared mailboxes though. But if the users don't have shell access the shared index files are probably a good idea anyway (at least from performance point of view). ** Symlink shares ** Currently the only way to implement shared mailboxes among users is for administrator to create symlinks. This will be possible in future too with a configuration like: namespace shared { prefix = Shared/ location = maildir:~/Maildir/shared-symlinks:INDEX=~/Maildir/ shared-indexes } The "owner" ACL won't match anyone. So it'll work exactly as it does now.

[Dovecot] dovecot + ldap + quota
by aza zel 27 Apr '07

27 Apr '07

hi.... i using dovecot 1.0rc26 and i started to configure quota plugin but i think its not working fine. i configure like suggested in http://wiki.dovecot.org/Quota in dovecot.conf: protocol imap { mail_plugins = quota imap_quota } plugin { # 10 MB quota limit quota = maildir:storage=10240 } in dovecot-ldap.conf: user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid,quotaStorage=quota if a mua send a attach near 9MB i receive a message tell me that the server don't have more space, but if i attach files of 2MB this messages are sending ok, and the cur directory of this user have 15 MB. another question: in ldap entry, the attribute quota are the attibute that A represents the quota on a mailbox, ¿so why i put 10MB as limit? uota = maildir:storage=10240 ¿this value is for all "entryes" or the quota limit is the entry quota limit? i you can see, i not understand how dovecot works with the attribute quota in ldap entry; ¿can anybody explain me this? Thanks in advance!!!

[Dovecot] Dovecot "assertion failed" errors
by Christian Friedli 27 Apr '07

27 Apr '07

Dear all, We are running Dovecot (on debian etch, Version 1.0.rc15-2) on 4 Loadbalanced servers using a NFS share for the homedirs. The loadbalancer is using persistant connections (timeout 30min). Lately, IMAP Users (mostly using Thunderbird) reported the following errors: 1. When trying to mark messages as read, nothing happened, message was still displayed as unread. 2. When moving a Directory the client loads for a long time and then hangs. Same was reported to happened when a user tried to open a mail. When checking the logs at the time users reported those errors we could always find one fo the following "assertion failed" errors: file mail-index-sync-update.c: line 730 (mail_index_sync_update_index): assertion failed: (view- >hdr.messages_count == map->hdr.messages_count) file mail-index.c: line 415 (mail_index_map_parse_keywords): assertion failed: (ext->hdr_offset < map->hdr.header_size) file mail-index.c: line 909 (mail_index_sync_from_transactions): assertion failed: (prev_seq <= max_seq && (prev_seq != max_seq || prev_offset <= max_offset)) file mail-transaction-log-view.c: line 158 (mail_transaction_log_view_set): assertion failed: (min_file_seq != max_file_seq || min_file_offset <= max_file_offset) file mail-transaction-log-view.c: line 229 (mail_transaction_log_view_set): assertion failed: (view->cur_offset <= view->cur->sync_offset) file message-body-search.c: line 393 (message_body_search_ctx): assertion failed: (input->v_offset <= part->physical_pos) I wonder if anyone has experienced similar problems and if there is a solution to this strange behaviour. ____________________________ University of Bern IT Department Central Systems Group Christian Friedli E-Mail Services Gesellschaftsstr. 6 CH-3012 Bern Switzerland Tel. +41 (0)31 631 38 38 Fax +41 (0)31 631 43 57 mailto:christian.friedli@id.unibe.ch http://www.mail.unibe.ch --

[Dovecot] sendmail + dovecot + vpopmail + virtual users, problem with pop3 uidl
by Oliver Schulze L. 27 Apr '07

27 Apr '07

Hi, I just migrated a server running qmail+vpopmail+maildir to sendmail+dovecot+maildir+vpopmail The migrating is working great thanks to the help from the list and the wiki. I'm now running the infamous problem about duplicating emails, because of pop3 UIDL mismatch. My question is: anyone knows that the pop3_uidl_format string for a vpopmail server? I'm using vpopmail auth and userdb. I noted that when manually issuing a list command to the vpopmail pop3 server, it uses a number that is in the filename for identifying the email. For example if the filename uses: .....,S=1234,... Then the UID is 1234, and 1234 appears in the list command.

[Dovecot] LSUB "" "" vs LIST "" "" (hacked Apple Mail problem)
by Eyvind Bernhardsen 27 Apr '07

27 Apr '07

The LSUB command does not act like LIST when provided with an empty mask argument. LIST responds with the hierarchy delimiter: * LIST (\Noselect) "." "" OK List completed. whereas LSUB doesn't return anything useful: OK Lsub completed. RFC 3501 doesn't specify what LSUB should do in this case, but Courier IMAP has LSUB act like LIST. The attached patch modifies imap/cmd-list.c to make Dovecot do the same. Why do I care about LSUB? I'm using a hack for Apple Mail that replaces its LIST command with LSUB (something like what's described here: http://www.macosxhints.com/article.php? story=20040407062603804), to prevent it from syncing public folders from the Exchange server at the office. The hack replaces _all_ LISTs with LSUBs, including the LIST "" "" Mail.app sends to discover the hierarchy delimiter. Since dovecot doesn't give it any information in response to LSUB "" "", Mail.app defaults to using "/" as a delimiter, which means that trying to access a subfolder only results in an "Invalid mailbox name" error. While this isn't really a bug in Dovecot, it's not inconceivable that other people than me could be affected by this problem (macosxhints.com has a substantial readership). It's also tricky to diagnose, especially since the "Invalid mailbox name" message doesn't include the invalid mailbox name, so any bug reports you get are likely to eventually be filed under "crazy [Mac] users". In fact, while Googling to figure out why Dovecot wasn't working for me, I came across at least one poster to this mailing list who had discovered that Mail.app was using "/" as a delimiter. I can't be sure, but I'm guessing that his problem was related to mine. Since the patch is tiny and doesn't hurt performance or make Dovecot do anything that contradicts the IMAP RFC, I hope you'll consider adding it to the official distribution. Eyvind Bernhardsen

[Dovecot] simple questions
by Nagyon Almos 27 Apr '07

27 Apr '07

Hello Everybody, I would like to use Dovecot on my desktop with imap but before doing the real migration I have some (very simple) questions: - Is there any way to log in with imap automatically ? That is, from localhost without any passwords. - Can Dovecot work with only readable maildirs? I want to avoid accidental e-mail loss, therefore on some maildir folder I have only read permissions. Or shall I use ACLs only? - Is there or Will there be a windows version? (In case I had to use windows.) Thanks for any help.

[Dovecot] Dovecot, Postfix and SMTP AUTH.... one more time...
by Bartosz Toczek 26 Apr '07

26 Apr '07

Hello. I've notice a problem with SMTP AUTH in postfix with dovecot. My configuration is based on Postgresql. I've created a function in postgresql which returns password and username and attached it to password_query. Query looks like this password_query = SELECT username_out as username, password_out as password FROM get_password(lower('%n'),lower('%d')); Problem is when get_password returns something like this... vmail=# SELECT username_out as username, password_out FROM get_password(lower(''),lower('')); LOG: statement: SELECT username_out as username, password_out FROM get_password(lower(''),lower('')); LOG: duration: 2.342 ms statement: SELECT username_out as username, password_out FROM get_password(lower(''),lower('')); username | password_out ----------+-------------- | (1 row) It returns 1 empty row.... When this is attached to postfix with smtp auth with such configuration # SMTP AUTH broken_sasl_auth_clients = yes smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = noanonymous smtpd_sasl_authenticated_header = yes smtpd_sasl_local_domain = smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth my serwer starts to be open relay... I now that it returns empty string for username and password... so where is the password checked... if I dont send password as a parameter to my function. Definition of the function looks like this: CREATE FUNCTION get_password("login" character varying, "domain" character varying, OUT username_out character varying, OUT password_out character varying) RETURNS record Can you help with that...

[Dovecot] bug? ldap auth CRAM-MD5

Hello list, our users are authenticated against ldap-server. anything works fine... dovecot: imap-login: Login: user=<xxx>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured but now we want to use secure passwords and not only plain over ssl. so we configured dovecot to use cram-md5 and configured the ldap-server with CRAM-MD5 passwords. as client we used thunderbird 2.0 and a webfrontend called roundcube. that does not work, because the server gives... dovecot: auth(default): ldap(xxx,127.0.0.1): Password mismatch then we tried to use DIGEST-MD5. we changed the ldap password to the created one with dovecotpw. but this doesnt work too. thunderbird requests CRAM-MD5 and not DIGEST-MD5. so the log says: dovecot: auth(default): password(xxx,127.0.0.1): Requested CRAM-MD5 scheme, but we have only DIGEST-MD5 imap-login: Aborted login: user=<xxx>, method=CRAM-MD5 after that we changed the password back to CRAM-MD5, but we mad the failure not to delete the DIGEST-MD5 value. so the users had 2 passwords set... {CRAM-MD5}e02d374fde0dc75a17a557039a3a5338c7743304777dccd376f332bee68d2cf6 {DIGEST-MD5}358aefa044c08e6c19711c8117714fb0 password is "test" in both cases. on the next try we start thunderbird it works. i dont know why and the log of dovecot says... auth(default): ldap(xxx,127.0.0.1): Multiple password values not supported imap-login: Login: user=<xxx>, method=CRAM-MD5, rip=127.0.0.1, lip=127.0.0.1, secured user was logged in using CRAM-MD5. it's not nice but it works. anyone have an idea why? because of apache-module to auth against ldap and apache doesnt support nor CRAM-MD5 or DIGEST-MD5 we have set the password third time using MD5. So every user has three same passwords with different encryptions. Not nice - but it works. But what can we do to change this.

Hi, now that a lot off software is updated e.g. RedHat EL and dovecot got finaly final :-) we plan to upgrade our mailserver from RHEL4 dovecot 0.99 to RHEL5 with dovecot 1.0rc15 - the rpms provided by Red Hat. I've read the upgrading Dovecot manual from here http://wiki.dovecot.org/UpgradingDovecot, but yust to get things right I'd like to ask some questions: Simply spoken, we use the basic default dovecot-config, mbox format and imaps/pop3s. So will there be any big trouble to just use the most default settings of the 1.0 config file? Or which options are compleatly different? Dose there exist a migration how to beside the dovecot upgrade from the wiki? Thanks for hints and tips!
