[Dovecot] expire plugin
by suzuki 23 Jun '10

23 Jun '10

Hello, I am testing expire plugin, with quota plugin enabled. When I execute expire-tool, maildirsize is not updated. Is there any solution to update maildirsize when executing expire-tool? # /usr/local/dovecot/sbin/dovecot --version 1.1.18 # /usr/local/dovecot/sbin/dovecot -n # 1.1.18: /usr/local/dovecot/etc/dovecot.conf # OS: FreeBSD 7.2-STABLE i386 base_dir: /var/run/dovecot/ syslog_facility: local4 protocols: pop3 ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot//login login_executable: /usr/local/dovecot/libexec/dovecot/pop3-login login_greeting: ready mail_max_userip_connections: 1 verbose_proctitle: yes first_valid_uid: 10026 last_valid_uid: 10026 first_valid_gid: 10026 last_valid_gid: 10026 mail_privileged_group: vmail mail_uid: 10026 mail_gid: 10026 mail_location: maildir:~/Maildir mail_debug: yes maildir_copy_preserve_filename: yes mail_executable: /usr/local/dovecot/libexec/dovecot/pop3 mail_plugins: quota expire mail_plugin_dir: /usr/local/dovecot/lib/dovecot/pop3 mail_log_max_lines_per_sec: 30 pop3_enable_last: yes pop3_reuse_xuidl: yes pop3_lock_session: yes pop3_client_workarounds: outlook-no-nuls,oe-ns-eoh lda: postmaster_address: postmaster mail_plugins: quota expire sendmail_path: /usr/local/sbin/sendmail auth_socket_path: /var/run/dovecot/auth-master auth default: verbose: yes passdb: driver: sql args: /usr/local/dovecot/etc/dovecot-sql.conf userdb: driver: sql args: /usr/local/dovecot/etc/dovecot-sql.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 user: vmail plugin: quota: maildir expire: Spam 7 expire_dict: proxy:/var/run/dovecot/dict-server:expire auth_socket_path: /var/run/dovecot/auth-master dict: expire: mysql:/usr/local/dovecot/etc/dovecot-dict-expire.conf

[Dovecot] More Dovecot 2.0 permissions issues
by Tim Traver 22 Jun '10

22 Jun '10

Hi Timo, ok, using the latest 2.0beta6... I can't figure out the settings for the log file to have the correct permissions. When the log file is created, it is created owned by root and 0600 permissions, which doesn't allow the lda to write to it if I use different users and groups for that main config... If I then chmod the log file to 666, then everything is happy, but again, if that log file is removed and created by dovecot, it will create it back with 0600 and the lda will error and not deliver mail because of it... I was not able to find anywhere else to set the mode of the log files or the mask that is used... here is the current config : # 2.0.beta6: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.0-RELEASE-p3 i386 auth_username_format = %Lu auth_username_translation = %@ auth_verbose = yes disable_plaintext_auth = no dotlock_use_excl = yes first_valid_uid = 100 listen = * lock_method = dotlock log_path = /local/logs/dovecot.errors mail_gid = 100 mail_location = maildir:%h/Maildir mail_nfs_index = yes mail_nfs_storage = yes mail_uid = 100 mmap_disable = yes passdb { args = /bin/checkpassword_dovecot_auth driver = checkpassword } plugin { quota = maildir sieve = ~/.dovecot.sieve sieve_dir = ~/Maildir/sieve } protocols = imap pop3 managesieve quota_full_tempfail = yes service auth { unix_listener auth-userdb { mode = 0660 } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = prefetch } userdb { args = /bin/checkpassword_dovecot_deliver driver = checkpassword } verbose_proctitle = yes protocol pop3 { pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } protocol lda { mail_plugins = quota sieve } protocol imap { mail_plugins = quota imap_quota } Thanks, Tim.

[Dovecot] Postfix, MySQL, Dovecot LDA and alias domains
by Darek M 22 Jun '10

22 Jun '10

Hi there, I have a postfix/postfixadmin/mysql/dovecot install that was using 'virtual' for the LDA. I tried the 'dovecot' LDA to enable Sieve but ran into trouble with aliases. With domain "some-domain.com" being an alias to "somedomain.com", mail sent to *(a)somedomain.com would be delivered to the Maildir fine, but the 'dovecot' LDA tossed "unknown user" for anything sent to *(a)some-domain.com (the alias to the other domain). My dovecot.sql: driver = mysql connect = host=/var/lib/mysql/mysql.sock dbname=postfix user=dovecot password=dovecot user_query = SELECT concat('/home/vmail/', maildir) as home, concat('maildir:/home/vmail/', maildir) as mail, 5000 AS uid, 5000 AS gid, concat('maildir:storage=', quota) AS quota FROM mailbox WHERE username = '%u' AND active = '1' password_query = SELECT username as user, password, concat('/home/vmail/', maildir) as userdb_home, concat('maildir:/home/vmail/', maildir) as userdb_mail, 5000 as userdb_uid, 5000 as userdb_gid FROM mailbox WHERE username = '%u' AND active = '1' The problem is fairly simple: Dovecot isn't being told anything about the 'alias_domain' table that pairs alias domains with actual ones. So the question is: do I add a second "user_query" in dovecot.sql, or is there an "alias_query" directive, or similar? And does anyone have a query that would point an alias domain to the real maildir? - Darek

[Dovecot] Outlook problem
by Patric Falinder 22 Jun '10

22 Jun '10

Hi, I have some problems that every time I start Outlook and retrieve my e-mails and then later tries to do it on my iPhone for example, I get some sort of problem that I can't get the mails. I searched around on the wiki and found the "outlook-no-nuls" and "outlook-idle" options, but where am I suppose to add them? I only have "pop3_uidl_format = %08Xu%08Xv" in my "protocol pop3 {}" and it didn't work to add it to a new line there. Thanks, Patric

[Dovecot] "failed to store into mailbox 'INBOX': Not enough disk space." with large mail

Hello, I am having this error message on some rare emails with more than 6 mb or so. Neither the dovecot server nor the filesystem where the maildir resides have any quota or are full at the time of delivering.

[Dovecot] New mailbox & autocreate
by Bambero 21 Jun '10

21 Jun '10

Hi, First of all BIG THANKS for great piece of software. I have a small problem with autocreate. My mails are stored in: /var/mail Ex. /var/mail/test(a)test.pl/Maildir Account information comes from DB. So when new account appears in DB full path including home dir is created. But there is one small problem: Group always is "wheel". Autocreating ignores gid from DB and uses the group of the parent directory - in this case /var/mail. But when I create home dir manualy (setting right group) group of autocreated Maildir is OK. Is it possible to configure dovecot to set group from DB. Regards, Bambero

[Dovecot] Error: dict: Leaked a t_pop() call
by Brendan McCollam 21 Jun '10

21 Jun '10

I'm running dovecot 1.0.7 on CentOS 5.5, and I've configured it to work with PostfixAdmin (http://sourceforge.net/projects/postfixadmin/) Everything seems to work great, except for one problem. Any time a user logs in, I get errors like the following Jun 19 02:21:59 ve dovecot: dict: Leaked a t_pop() call in I/O handler (nil) Jun 19 02:21:59 ve dovecot: dict: Raw backtrace: dict [0x40e85e] -> dict [0x40e5cc] -> dict(io_loop_handler_run+0x1c9) [0x411279] -> dict(io_loop_run+0x18) [0x4106b8] -> dict(main+0x139) [0x408509] -> /lib64/libc.so.6(__libc_start_main+0xf4) [0x2ab19ec13994] -> dict[0x407589] The only information I could find online was from this mailing list a few years back: http://copilotco.com/mail-archives/dovecot.2007/msg08975.html The response seems to be "nobody keeps their quota in MySQL", but the setup I'm using is what's recommended by the authors of PostfixAdmin: http://postfixadmin.svn.sourceforge.net/viewvc/postfixadmin/trunk/DOCUMENTS… So, I guess my questions are these: 1) Is this error at all serious? Will it impact performance, or can it be safely ignored? 2) If it is something that should be addressed, do you think I would be better off trying to patch and recompile the 1.0.7 version, or just upgrading to a newer version of Dovecot (keeping in mind that 1.0.7 seems to be the latest available in CentOS repositories) Thank you for your time, and your outstanding software. -Brendan

Thanks for the information. I'm not trying to waste your time, and I wasn't really asking for 'help' per se, as much as simply a clear answer about whether that error was even worth worrying about. I'm well aware that 1.0.7 is a pretty old release, and you don't have much control over what the distro maintainers choose to package. Generally speaking, I think there are advantages (not introducing incompatibility with other software, simple dependency resolution, automatic security updates, etc.) to sticking with repo versions, unless you have a compelling reason to do otherwise. In this case, the bugfixes and improvements in quota accuracy are a good reason to upgrade. > > Please download 1.2.12, the current stable release, however read the > release notes because some settings will be incompatible with 1.0.x. > there wont be too many differences but might be some, depending on your > setup. I have moved to 1.2.12 and updated my dovecot-dict-quota.conf file, and it seems to be working great. Thanks again.

[Dovecot] confused with %d/%n not working....
by William Ottley 21 Jun '10

21 Jun '10

Hi all, I'm trying to link in my "online" community of users, via mysql, with my mailserver. I have dovecot 1.0.7. I am using mysql to authenticate, and I'm trying to figure out what I should be doing to my sql query that checks the username which has a username field and a database field. everything works, as long as the username is "u%@d%" in the field, but to work with my other web application, the username is in one field, and the database is in another. can anyone make a suggestion as to how i can do the user_query to work this way? (both with dovecot and the postfix) any help would be greatly appreciated! dovecot: connect = host=localhost dbname=pplsnet user=xxxx password=xxxxxxx password_query = SELECT password FROM mailbox WHERE username = '%u' user_query = SELECT '/var/vmail/%d/%n' as home, 'maildir:/var/vmail/%d/%n' as mail, 150 AS uid, 12 AS gid, concat('dirsize:storage=',quota) AS quota FROM mailbox WHERE username ='%u' AND active ='1' postfix: user = mail password = xxxx hosts = localhost dbname = mail table = mailbox select_field = CONCAT(domain,'/',maildir) where_field = username additional_conditions = and active = '1'

Big thanks for improvements in svn-trank Roundcube version, I am waiting for official release for update. Timo-san, which client most Dovecot compatible you think (non-Web)?? I want to do more tests.

[Dovecot] coredump while accessing virtual folder with dovecot 2.0
by Matthias Rieber 20 Jun '10

Hi, I get a core dump with 2.0.beta6 (573cb66e9180) when I access virtual folders with the master user. Since ACLs are active I have to set a global ACL in .DEFAULTS to access all folders. Coredump: Core was generated by `dovecot/imap'. Program terminated with signal 11, Segmentation fault.

[Dovecot] Sieve isn't working
by Steven Weiß 20 Jun '10

20 Jun '10

Hi, I tried to get Sieve plugin running but I don't get it to work and actually have no idea what's wrong. My dovecot version is 1.2.12 and dovecot -n prints this: # 1.2.12: /usr/local/etc/dovecot.conf # OS: Linux 2.6.18-028stab064.7 i686 openSUSE 11.1 (i586) reiserfs log_path: /var/log/dovecot.log info_log_path: /var/log/dovecot.log disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login first_valid_uid: 110 last_valid_uid: 110 mail_location: maildir:/var/qmail/mailnames/%d/%n/Maildir fsync_disable: yes lda: postmaster_address: postmaster(a)code-factory.de mail_plugins: sieve mail_plugin_dir: /usr/local/lib/dovecot/lda fsync_disable: no auth default: passdb: driver: passwd-file args: /usr/local/etc/passwd.dovecot userdb: driver: passwd userdb: driver: static args: uid=popuser gid=popuser plugin: sieve: /var/mail/mydomain/.dovecot.sieve sieve_global_path: /var/lib/dovecot/sieve/default.sieve sieve_dir: /var/mail/mydomain/sieve sieve_global_dir: /var/lib/dovecot/sieve/global/ For testing purposes I created a very simple /var/mail/mydomain/.dovecot.sieve with the following content: require ["fileinto", "regex"]; if address :is "from" "test(a)test.de" { fileinto "INBOX.Webi"; stop; } Then I sent a mail from test(a)test.de (the real address is ommitted here) to my mail account, but the mail is not moved to the subfolder Webi. In the log files there's no single hint what's going on. And in /var/mail/mydomain there's no .dovecot.sieve.log file. This directory is owned by popuser and that user has rights for reading and writing to this directory (and read rights for .dovecot.sieve), therefore it should not be a rights problem. Does anybody has suggestions what could be the cause of this? Sincerely, Steven

Changelog Sieve v0.1.17: - Made sure source code positions for compiler messages are recorded at start of tokens. - Fixed a few potential memory leaks in the Sieve compiler and the spam/virustest extensions. - Made command line tools return proper exit status upon failure. The release is available as follows: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.17.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.17.tar.gz.sig Refer to http://pigeonhole.dovecot.org for more information. Have fun testing the new releases and don't hesitate to notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

http://dovecot.org/releases/1.2/dovecot-1.2.12.tar.gz http://dovecot.org/releases/1.2/dovecot-1.2.12.tar.gz.sig Some of the most important fixes since v1.2.11: - deliver: Don't crash when a message with Auto-submitted: header gets rejected. - lib-storage: Fixed header searches to work correctly when there are multiple headers with same name. - dict client: Disconnect from dict server after 1 second of idling. - dict: If process crashed, it wasn't automatically restarted - dict file: If dict file's group permissions equal world permissions, don't try to change its gid. - maildir: Fixed a memory leak when copying with hardlinks. - maildir: Expunging last messages may have assert-crashed if their filenames had just changed.

[Dovecot] Dovecot 2.0 auth socket error
by Tim Traver 18 Jun '10

18 Jun '10

Hi Timo, ok, when dovecot starts up, it creates the socket files in /usr/local/var/run/dovecot for the auth and a variety of other socket stuff you have going on. It creates these socket files with root ownership. But I have in the config files that dovecot is running as a particular user (in this case uid100 and gid100) to match the global mail systems needs. I use qmail as the delivery agent, and when qmail envokes deliver, I get the following errors in the qmail log files : @400000004c1b18f22ea7a05c delivery 1497: deferral: lda:_Error:_userdb_lookup:_connect(/usr/local/var/run/dovecot/auth-userdb)_failed:_Permission_denied_(euid=100(sn)_egid=100(sn)_missing_+w_perm:_/usr/local/var/run/dovecot/auth-userdb,_euid_is_not_dir_owner)/lda:_Fatal:_Internal_error_occurred._Refer_to_server_log_for_more_information./ Now, from what I can tell, this is complaining that the socket doesn't have write permission for the group, because it is owned by root and created with only 600 permissions...I can chmod the file to add the rw for the group, and then it appears to start working ok, but if I stop and start dovecot, it will only re-create those files with the 600 permissions... It appears that this is not happening in the version 1.2.11 code base as I this machine is a new one that I am testing 2.0 code on... Am I missing a proper setting somewhere? here is my dovecot -l : # 2.0.beta6: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.0-RELEASE-p3 i386 auth_username_format = %Lu auth_username_translation = %@ auth_verbose = yes disable_plaintext_auth = no dotlock_use_excl = yes first_valid_uid = 100 listen = * lock_method = dotlock log_path = /local/logs/dovecot.errors mail_gid = 100 mail_location = maildir:%h/Maildir mail_nfs_index = yes mail_nfs_storage = yes mail_uid = 100 mmap_disable = yes passdb { args = /bin/checkpassword_dovecot_auth driver = checkpassword } plugin { quota = maildir sieve = ~/.dovecot.sieve sieve_dir = ~/Maildir/sieve } protocols = imap pop3 managesieve quota_full_tempfail = yes ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = prefetch } userdb { args = /bin/checkpassword_dovecot_deliver driver = checkpassword } verbose_proctitle = yes protocol pop3 { pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } protocol lda { mail_plugins = quota sieve } protocol imap { mail_plugins = quota imap_quota } Thanks, Tim.

[Dovecot] strange regex sieve filter error
by Tim Traver 18 Jun '10

18 Jun '10

Hi all, ok, I'm getting an error produced by the following sieve file : require ["fileinto","copy"]; # rule:[SPAM-TAG] if allof ( header :regex "Subject" "^\\[SPAM-TAG\\]") { fileinto "SPAM-TAG"; stop; } and I'm getting the following error in the dovecot delivery log : main_script: line 3: error: unknown tagged argument ':regex' for the header test (reported only once at first occurence). main_script: error: validation failed. But I looked up the syntax, and tried to figure out why this is getting the error. I guess I just don't quite know what this error means... I know that the value that it is trying to match is kind of strange, but it is a regular expression, so it should work... Thanks, Tim.

[Dovecot] Problem configuring rawlog with 2.0beta6
by Mark Sapiro 18 Jun '10

18 Jun '10

The initial problem I was seeing after upgrade from 2.0beta5 to 2.0beta6 was error messages from my Android phone K9 client that dovecot was reporting -1 messages in various mailboxes. These mailboxes do have the special "Mail System Internal Data" message in them. In trying to get more information for debugging, I tried toenable rawlog using the same configuration I used successfully with 2.0beta5, namely: service imap { executable = imap imap-postlogin } service imap-postlogin { executable = script rawlog unix_listener imap-postlogin { } } (full dovecot -n below), but instead of successful rawlog writes, I got the following log messages: Jun 16 19:46:36 sbh16 dovecot: script: Fatal: Client not compatible with this binary (connecting to wrong socket?) Jun 16 19:46:36 sbh16 dovecot: imap: Error: fd_read(/usr/local/var/run/dovecot/imap-postlogin) failed: disconnected So the first question is how do I configure rawlog for 2.0beta6? And the next question is why the "-1 messages".

[Dovecot] LDA to address extensions
by Martijn de Munnik 18 Jun '10

Hi List, I'm trying to make dovecot deliver messages to sam+extension(a)example.com to the imap folder 'extension' of the user 'sam'. I've configured postfix with these dovecot as LDA: mailbox_command = /opt/redknot/libexec/dovecot/deliver -f "$SENDER" -d "$USER" -m "$EXTENSION" -a "$RECIPIENT" recipient_delimiter = + Sam is a local system user so I don't want to use virtual_transport (I think).

[Dovecot] \Noselect on virtual folders
by Matthias Rieber 17 Jun '10

17 Jun '10

Hi, I've some virtual folders which seem a bit odd when they are listed. a LIST "virtual.spam." "*" * LIST (\Noselect \HasNoChildren) "." "virtual.spam." * LIST (\HasNoChildren) "." "virtual.spam.unchecked" * LIST (\Noselect \HasChildren) "." "virtual.spam.disagree" * LIST (\HasNoChildren) "." "virtual.spam.disagree.dspam" * LIST (\HasNoChildren) "." "virtual.spam.disagree.spamassassin" a OK List completed. This seems ok, virtual.spam and virtual.spam.disagree can't contain mails. I'm wondering if virtual.spam should have the flag \HasChildren instead if \HasNoChildren, but this doesn't cause trouble... a LIST (SUBSCRIBED) "virtual.spam." "*" * LIST (\Subscribed \Noselect) "." "virtual.spam.disagree.spamassassin" * LIST (\Subscribed \Noselect) "." "virtual.spam.disagree.dspam" * LIST (\Subscribed \Noselect) "." "virtual.spam.unchecked" a OK List completed. When I list the folder with (SUBSCRIBED), the virtual folders are all flagged with \Noselect. This appears at all virtual folders. All other folders don't have the \Noselect flag. On the Nokia N900 I can't enter all virtual folders. The log shows that the n900 always list the folders with (SUBSCRIBED). Is this listing the expected behaviour? regards, Matthias

[Dovecot] Shared mailboxes errors
by Nikita Koshikov 17 Jun '10

17 Jun '10

Hello list, I'm implementing shared mailboxes on live system and after enabling acl plugin I got errors in my log: Jun 17 15:50:33 dict: Error: sql dict iterate: Invalid/unmapped path: shared/shared-boxes/anyone/ I have no clue why this happening, users don't know about new functionality they just use imap as before. Also dict database begin to fill up by records like: select * from user_shares; user@domain.com|admin@domain.com|1 But user don't use setacl command. Searching for the list gave http://www.dovecot.org/list/dovecot/2009-April/038664.html , but question seemed still open. So, can someone give point how to fix\avoid this ? One more question, on live system it's hard to debug dovecot with mail_debug=yes for all users, can this option be turn on for individual user? or maybe mail_debug stream can be redirected also for individual user ?

[Dovecot] basic conf error? v1.2.11

17 Jun '10

I just downloaded 1.2.11 and compiled from source including mysql support and using default directory locations. I walked thru the included example conf file and tweaked it out and get an invalid configuration file. I trimmed out all of the commented sections to make the non-default config super easy to navigate during troubleshooting. Remaining config which gives an error of "unknown setting: mechanisms" so I switched it to auth_mechanisms and then get the following when starting dovecot: Error: Error in configuration file /usr/local/etc/dovecot.conf line 18: Unknown section type (section changed in /usr/local/etc/dovecot.conf at line 14) Fatal: Invalid configuration in /usr/local/etc/dovecot.conf ##################### protocols = imap pop3 listen = <SCRUBBED IP> disable_plaintext_auth = no ssl = no login_processes_count = 100 login_max_processes_count = 500 login_max_connections = 512 login_greeting = DovecotProxy08 ready. protocol imap { } protocol pop3 { } protocol lda { } #LINE 14 auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@/$!&\ auth default { mechanisms = plain passdb sql { #LINE 18 args = /usr/local/etc/dovecot-sql.conf } userdb sql { args = /usr/local/etc/dovecot-sql.conf } user = root } dict { } plugin { } ##################### Any ideas what is wrong here?

[Dovecot] ZFS Index corruption and Connection reset by peer
by Philippe Chevalier 17 Jun '10

17 Jun '10

Hello, I'm currently using dovecot 1.2.11 on FreeBSD 8.0 with ZFS filesystems. So far, so good, it works quite nicely, but I have a couple glitches. Each user has his own zfs partition, mounted on /home/<user> (easier to set per user quotas) and mail is stored in their home. From day one, when people check their mail via imap, a lot of indexes corruption occured : dovecot: IMAP(<user>@domain.org): Corrupted transaction log file /home/<user>/Mail/Maildir/INBOX/dovecot.index.log seq 13: record size too small +(type=0x0, offset=5560, size=0) (sync_offset=5652) dovecot: IMAP(<user>@domain.org): fscking index file /home/<user>/Mail/Maildir/INBOX/dovecot.index dovecot: IMAP(<user>@domain.org): /home/<user>/Mail/Maildir/INBOX/dovecot.index log position went backwards (13,132 < 13,5560) dovecot: IMAP(<user>@domain.org): Transaction log file /home/<user>/Mail/Maildir/INBOX/dovecot.index.log: marked corrupted etc, etc... After some digging, I "solved" this problem with mmap_disable = yes in dovecot.conf. Index corruption doesn't seem to occur anymore. Is this normal? I thought this problem occured only on NFS filesystem and eventually on old versions of ZFS. Hasn't this been fixed? Is there an option in ZFS that would allow mmap calls without corruption. Has it something to do with compression ? The options of the zfs filesystem are : zhome/username type filesystem - zhome/username creation Thu Mar 18 11:10 2010 - zhome/username used 750M - zhome/username available 61.0G - zhome/username referenced 750M - zhome/username compressratio 1.20x - zhome/username mounted yes - zhome/username quota none default zhome/username reservation none default zhome/username recordsize 128K default zhome/username mountpoint /usr/home/username inherited from zhome zhome/username sharenfs off default zhome/username checksum on default zhome/username compression lzjb inherited from zhome zhome/username atime off inherited from zhome zhome/username devices on default zhome/username exec on default zhome/username setuid on default zhome/username readonly off default zhome/username jailed off default zhome/username snapdir hidden default zhome/username aclmode groupmask default zhome/username aclinherit restricted default zhome/username canmount on default zhome/username shareiscsi off default zhome/username xattr off temporary zhome/username copies 1 default zhome/username version 3 - zhome/username utf8only off - zhome/username normalization none - zhome/username casesensitivity sensitive - zhome/username vscan off default zhome/username nbmand off default zhome/username sharesmb off default zhome/username refquota none default zhome/username refreservation none default zhome/username primarycache all default zhome/username secondarycache all default zhome/username usedbysnapshots 0 - zhome/username usedbydataset 750M - zhome/username usedbychildren 0 - zhome/username usedbyrefreservation 0 - Other problem, that I have been unable to solve so far, is that a lot of entries show up in my logs about : dovecot: imap-login: net_disconnect() failed: Connection reset by peer It doesn't seem to have any adverse effect, except it's filling up the logs. It seem to appear when a client closes the imap connection? Is there a way to suppress this error? Regard P.C.

[Dovecot] BUG Dovecot 1.0.15 and Apples Mail.app
by Gerhard Waldemair 17 Jun '10

17 Jun '10

Is there anyone using Apple´s Mail.app to collect the mails via IMAP or IMAPS ? I found a funny bug in Debian Lennys Dovecot Version. (still v. 1.0.15) When I get my Mails via IMAP or IMAPS and define a Rule in Mail.app to move the eMail to s specific folder I will find the mail 2 times in the folder. After a minute or so the double Mail disappears. I have tried it with other programs like Thunderbird. There everything works, v1.0 too. Now I have updatet Dovecot from 1.0 to 1.2 from Backports and everything works great now !!!!! Regards, Gerhard PS in Squeeze Dovecot is Version 1.2

[Dovecot] dovecot vs. Thunderbird
by Bodo Schulz 17 Jun '10

17 Jun '10

Hello (and Moin Moin) ;) I have currently a straith Problem ... I have our IMAP-Server migrated from an old cyrus the the current stable Version of dovecot. In the old configuration we organized many mails (e.g. root-Stuff) in Public Folders. They structure had nearly 5 folderlevels.

[Dovecot] Ok with a bit more wiki reading ...
by Chuck McManis 17 Jun '10

17 Jun '10

So if I want to run dovecot from tcpserver it seems like I can simply run `pop3-login --ssl` from tcpserver (its sort of like running it from inetd) and it says it will 'talk to dovecot'. Can I disable all listeners in dovecot then? Will is still talk to it? Trying some experiments now ... --Chuck

[Dovecot] Migrating from CommunigatePro to Dovecot - anyone done this?
by Gavin Lawrie 17 Jun '10

17 Jun '10

Apologies if this is in the archive - did look but couldn't find it. Does anyone have any experience of migrating from CommunigatePro to Dovecot? We currently run CGP 5.3.4, supporting a small system (20 or so users, one domain). We've been using it for years, and have a mixed bag of MailDir and mbox folders accessed via IMAP clients. Some users have large mail accounts (15GB total). We're looking to move as CGP is evolving into a complex "Messaging Centre" application (PBX, SIP, Mail, Groupware, Portals etc.) which we don't need / use. I had a look on the Dovecot Wiki and under migration are discussions about various other mail systems, but I don't know enough about these to tell if they would also apply to CGP. Any thoughts / suggestions would be welcomed. Thanks Gavin. * Balanced Scorecard Training from 2GC: Next course 16th July 2010 in the UK.

[Dovecot] search bug?
by Pozsar Balazs 16 Jun '10

16 Jun '10

Hi all, I have emails with multiple Delivered-To: headers in them. The problem is that the SEARCH command only searches in the first instances. For example: 1 FETCH 14557 BODY[HEADER.FIELDS (Delivered-To)] * 14557 FETCH (BODY[HEADER.FIELDS (DELIVERED-TO)] {85} Delivered-To: pozsy(a)ojjektum.uhulinux.hu Delivered-To: szamlagyar(a)uhusystems.com ) 1 OK Fetch completed. 1 SEARCH HEADER Delivered-To szamlagyar(a)uhusystems.com * SEARCH 14589 1 OK Search completed (0.146 secs). You can see the meesage with the id 14557 _has_ a "Delivered-To: szamlagyar(a)uhusystems.com" header field, but the SEARCH does not find it, only another message. This is with dovecot 1.2.11. For the record, cyrus-imapd behaves as I would have expected, and I could not find anything relevant in the RFCs. Could anyone tell me if this is a bug, or how to search like I would want? Thanks, Balazs Pozsar

[Dovecot] New admin, not much success
by Chuck McManis 16 Jun '10

16 Jun '10

Hello, I'm trying to set up something fairly simple (famous last words) using Dovecot. I have a very small setup (just a dozen users) I'm using qmail as my MTA. I'm running FreeBSD 8.0 I've got qmail delivering into a file named 'Mailbox' in user's home directories. I prefer not to use Maildir delivery because from a shell its a PITA to get a Maildir aware MUA (I use /bin/mail when I'm attached locally) What I'm trying to do is configure an SSL only POP3 server so that folks can retrieve their email on the road without divulging their passwords. My backup scenario is to put VPN software on my user's clients and having them VPN into the network and then do un-encrypted POP3 from the VPN. I prefer not to do this as it means maintaining the VPN client as well. Users have a mix of MacOS, Windows, and Linux. So, I can't get dovecot to work at all. In an unusual turn about I got the SSL stuff working but not the mailbox handling. I'm running 2.0beta6 Output from dovecot -n ------------------------------------------------------------------------------------ # 2.0.beta6: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.0-RELEASE-p2 i386 nfs auth_debug = yes auth_verbose = yes default_internal_user = nobody default_login_user = nobody listen = * mail_full_filesystem_access = yes mail_location = mbox:/home/%u/:INBOX=/home/%u/ passdb { driver = pam } protocols = pop3 service pop3-login { inet_listener pop3s { port = 995 ssl = yes } } service pop3 { process_limit = 1024 } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } ----------------------------------------------------------------------- A typical failure looks like this in maillog: Jun 15 22:19:20 eeebox dovecot: master: Dovecot v2.0.beta6 starting up Jun 15 22:20:29 eeebox dovecot: pop3-login: Login: user=<cmcmanis>, method=PLAIN, rip=66.125.189.27, lip=66.125.189.30, mpid=78871, TLS Jun 15 22:20:29 eeebox dovecot: pop3(cmcmanis): Error: Opening INBOX failed: Mailbox isn't selectable Jun 15 22:20:29 eeebox dovecot: pop3(cmcmanis): Error: Couldn't open INBOX: Mailbox isn't selectable Jun 15 22:20:29 eeebox dovecot: pop3(cmcmanis): Couldn't open INBOX top=0/0, retr=0/0, del=0/0, size=0 -------------------------------------------------------------- Home directories are mounted via NFS and root doesn't have access, but if dovecot accesses the Mailbox as the user it should work fine. I'm about ready to start hacking in additional logging into mail-storage.c to figure out what "mailbox isn't selectable" means. --Chuck

[Dovecot] Logout after SSL/TLS negociation
by bmfr 16 Jun '10

16 Jun '10

Hi All, I've set up Dovecot to use my signed SSL certificate and IMAP client is using STARTTLS on port 143 without secure authentication. The TLS negociation process seems to go through ok but once the negociation is finished the client sends an IMAP LOGOUT message; he does not try to authenticate, below is the Dovecot's info log: dovecot: 2010-06-15 15:37:01 Info: auth(default): new auth connection: pid=3932 dovecot: 2010-06-15 15:37:03 Info: imap-login: Aborted login (0 authentication attempts): rip=130.100.32.54, lip=10.0.3.3, TLS I've decrypted the TLS negociation thanks to Wireshark (in SSL preferences I added the certificate's private key to decode the stream between client and server) but unfortunately it does not say why the client is sending the LOGOUT command. Do you have an idea of what could be wrong in my server set up? What debugging process would you advise me to follow? Thanks a lot for your precious help.

[Dovecot] A new director service in v2.0 for NFS installations
by Timo Sirainen 16 Jun '10

16 Jun '10

As http://wiki.dovecot.org/NFS describes, the main problem with NFS has always been caching problems. One NFS client changes two files, but another NFS client sees only one of the changes, which Dovecot then assumes is caused by corruption. The recommended solution has always been to redirect the same user to only a single server at the same time. User doesn't have to be permanently assigned there, but as long as a server has some of user's files cached, it should be the only server accessing the user's mailbox. Recently I was thinking about a way to make this possible with an SQL database: http://dovecot.org/list/dovecot/2010-January/046112.html The company here in Italy didn't really like such idea, so I thought about making it more transparent and simpler to manage. The result is a new "director" service, which does basically the same thing, except without SQL database. The idea is that your load balancer can redirect connections to one or more Dovecot proxies, which internally then figure out where the user should go. So the proxies act kind of like a secondary load balancer layer. When a connection from a newly seen user arrives, it gets assigned to a mail server according to a function: host = vhosts[ md5(username) mod vhosts_count ] This way all of the proxies assign the same user to the same host without having to talk to each others. The vhosts[] is basically an array of hosts, except each host is initially listed there 100 times (vhost count=100). This vhost count can then be increased or decreased as necessary to change the host's load, probably automatically in future. The problem is then of course that if (v)hosts are added or removed, the above function will return a different host than was previously used for the same user. That's why there is also an in-memory database that keeps track of username -> (hostname, timestamp) mappings. Every new connection from user refreshes the timestamp. Also existing connections refresh the timestamp every n minutes. Once all connections are gone, the timestamp expires and the user is removed from database. The final problem then is how multiple proxies synchronize their state. The proxies connect to each others forming a connection ring. For example with 4 proxies the connections would go like A -> B -> C -> A. Each time a user is added/refreshed, a notification is sent to both directions in the ring (e.g. B sends to A and C), which in turn forward it until it reaches a server that has already seen it. This way if a proxy dies (or just hangs for a few seconds), the other proxies still get the changes without waiting for it to timeout. Host changes are replicated in the same way. It's possible that two connections from a user arrive to different proxies while (v)hosts are being added/removed. It's also possible that only one of the proxies has seen the host change. So the proxies could redirect users to different servers during that time. This can be prevented by doing a ring-wide sync, during which all proxies delay assigning hostnames to new users. This delay shouldn't be too bad because a) they should happen rarely, b) it should be over quickly, c) users already in database can still be redirected during the sync. The main complexity here comes from how to handle proxy server failures in different situations. Those are less interesting to describe and I haven't yet implemented all of it, so let's just assume that in future it all works perfectly. :) I was also thinking about writing a test program to simulate the director failures to make sure it all works. Finally, there are the doveadm commands that can be used to: 1) List the director status: # doveadm director status mail server ip vhosts users 11.22.3.44 100 1312 12.33.4.55 50 1424 1) Add a new mail server (defaults are in dovecot.conf): # doveadm director add 1.2.3.4 2) Change a mail server's vhost count to alter its connection count (also works during adding): # doveadm director add 1.2.3.4 50 3) Remove a mail server completely (because it's down): # doveadm director remove 1.2.3.4 If you want to slowly get users away from a specific server, you can assign its vhost count to 0 and wait for its user count to drop to zero. If the server is still working while "doveadm director remove" is called, new connections from the users in that server are going to other servers while the old ones are still being handled.
