[Dovecot] Dovecot refuses connections
by John Rowe 11 May '07

11 May '07

I have recently upgraded to dovecot 1.0.0 on two machines running Scientific Linux 4.3/4.4 x86_64 kernel 2.6.9-22.0.1.EL. The systems come with openssl 0.9.7a and I have installed openssl-0.9.8e. Everything is 64-bit. /usr/local64/sbin/dovecot -n # /usr/local64/etc/dovecot.conf disable_plaintext_auth: no login_dir: /usr/local64/var/run/dovecot/login login_executable: /usr/local64/libexec/dovecot/imap-login first_valid_uid: 100 mail_extra_groups: mail default_mail_env: mbox:%h/mail:INBOX=/var/spool/mail/%u mail_location: mbox:%h/mail:INBOX=/var/spool/mail/%u mail_debug: yes mmap_disable: yes lock_method: dotlock mbox_read_locks: lockf mbox_write_locks: lockf auth default: passdb: driver: pam userdb: driver: passwd I have two issues: 1. It won't start from xinetd. I get very little in the logs, just: Apr 7 07:07:41 xyz xinetd[2545]: START: imaps pid=17445 from=144.173.228.126 Apr 7 07:07:41 xyz xinetd[2545]: EXIT: imaps pid=17445 duration=0(sec) where 'xyz' is the host name 2. If I instead I run dovecot as a daemon then both my machines have suffered the problem where dovecot runs for several days and then disallows connections with: Apr 29 04:06:07 xyz dovecot: imap-login: opendir(.) failed when trying to get list of authentication servers: Permission denied Apr 29 04:06:07 xyz last message repeated 2 times Apr 29 04:06:07 xyz dovecot: child 5645 (login) returned error 89 Apr 29 04:06:07 xyz dovecot: child 5646 (login) returned error 89 Apr 29 04:06:07 xyz dovecot: child 5647 (login) returned error 89 Killing and restarting dovecot seems to fix it. Thanks for your help. John

[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

Would someone please help with this error. Using: dovecot-1.0-2.rc28.fc6 On: Fedora Core 6 130 users all connect remotely via ADSL to server to pop their email. None of them have any problems at all with pop3. 3 users in one office, connect to the server via a NAT'd ADSL. Intermittently those three users will get a timeout error, Logfile shows: Apr 19 12:50:53 mail dovecot: auth(default): pam(vu0095,165.228.62.107): lookup service=dovecot Apr 19 12:50:53 mail dovecot: auth(default): client out: OK 1 user=vu0095 Apr 19 12:50:53 mail dovecot: auth(default): master in: REQUEST 376 12300 1 Apr 19 12:50:53 mail dovecot: auth(default): passwd(vu0095,165.228.62.107): lookup Apr 19 12:50:53 mail dovecot: auth(default): master out: USER 376 vu0095 system_user=vu0095 uid=580 gid=580 home=/home/vu0095 Apr 19 12:50:53 mail dovecot: pop3-login: Login: user=<vu0095>, method=PLAIN, rip=165.228.62.107, lip=203.36.211.209 Apr 19 12:51:49 mail dovecot: POP3(vu0095): Disconnected for inactivity in reading our output top=0/0, retr=1/0, del=0/2, size=25266 Apr 19 12:51:49 mail dovecot: POP3(vu0095): Disconnected: Logged out top=0/0, retr=2/25393, del=2/2, size=25266 99% of the time everything is perfect, it is only the three users in the one office that get this error, it is of course the head office for the customer and so they are very upset, because they get timeout errors on their email clients. They are using different versions of outlook, and outlook express, I have deactivated all nortons email scanning etc Have set the three email clients to pop mail at different times, eg. 7, 13, 17 minutes to try an avoid the possibility of simultaneous pop requests from the one IP address.

[Dovecot] read only maildir

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

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 :(..

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. The mail syslog shows e.g.: Apr 27 08:50:26 gateway dovecot: POP3(mk): Disconnected: Mailbox is in inconsistent state. top=0/0, retr=0/0, del=0/715, size=20210522 # /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login first_valid_uid: 440 mail_extra_groups: mail maildir_copy_with_hardlinks: yes mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv auth default: user: dovecot-login verbose: yes passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/run/dovecot/auth-client mode: 432 master: path: /var/run/dovecot/auth-master mode: 384 plugin: quota: fs Amon Ott -- Amon Ott - m-privacy GmbH Am Köllnischen Park 1, 10179 Berlin Tel: +49 30 24342334 Fax: +49 30 24342336 Web: http://www.m-privacy.de Handelsregister: Amtsgericht Charlottenburg HRB 84946 Geschäftsführer: Dipl.-Kfm.
