[Dovecot] Sieve plugin
by Luigi Rosa 11 May '07

11 May '07

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." Why isn't a good idea? Ciao, luigi -- / +--[Luigi Rosa]-- \ Every time you've heard someone say they saw a ghost, or an angel.

[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 :(.. 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......... I set everything under /var/run/dovecot to 600, owned by root:dovecot > 4242 root@mercury:/var/run/dovecot ## ls -alR > total 24 > drw------- 3 root dovecot 512 Mar 06 15:27 ./ > drwxr-xr-x 3 root system 512 Apr 18 2006 ../ > drw------- 2 root dovecot 512 May 09 10:37 login/ > ./login: > total 24 > drw------- 2 root dovecot 512 May 09 10:37 ./ > drw------- 3 root dovecot 512 Mar 06 15:27 ../ > srw------- 1 root dovecot 0 May 09 10:37 default= > -rw------- 1 root dovecot 230 May 09 10:36 ssl-parameters.dat > And restarted dovecot > 4243 root@mercury:/var/run/dovecot ## dovecot > but apparently /var/run/dovecot/login should be 750, but DC dealt with that automagically > Warning: Corrected permissions for login directory /var/run/dovecot/login > 4244 root@mercury:/var/run/dovecot ## ls -alR > total 24 > drw------- 3 root dovecot 512 Mar 06 15:27 ./ > drwxr-xr-x 3 root system 512 Apr 18 2006 ../ > drwxr-x--- 2 root dovecot 512 May 10 12:47 login/ > ./login: > total 24 > drwxr-x--- 2 root dovecot 512 May 10 12:47 ./ > drw------- 3 root dovecot 512 Mar 06 15:27 ../ > srwxrwxrwx 1 root dovecot 0 May 10 12:47 default= > -rw------- 1 root dovecot 230 May 09 10:36 ssl-parameters.dat > ...but then got in the syslog > May 10 12:49:51 mercury mail:err|error dovecot: imap-login: Can't open SSL param > eter file ssl-parameters.dat: Permission denied > May 10 12:49:51 mercury mail:err|error dovecot: child 1380384 (login) returned error 89 > > So I made it 640 which seems to do. > 4246 root@mercury:/var/run/dovecot ## chmod 640 login/ssl-parameters.dat > 4247 root@mercury:/var/run/dovecot ## ls -alR login > total 24 > drwxr-x--- 2 root dovecot 512 May 10 12:47 ./ > drw------- 3 root dovecot 512 Mar 06 15:27 ../ > srwxrwxrwx 1 root dovecot 0 May 10 12:47 default= > -rw-r----- 1 root dovecot 230 May 09 10:36 ssl-parameters.dat So it seems this will do (for others who obsess over things small):: a) /var/run/dovecot can be 600, root:dovecot b) /var/run/dovecot/login should be 750, root:dovecot c) /var/run/dovecot/login/ssl-parameters.dat might be 640, root: dovecot -- ==== 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

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
