[Dovecot] virtual namespace question
by Josephus 19 Jan '10

19 Jan '10

Hi, I'm wondering if it is possible to create a virtual namespace on a prefix other than "virtual/". My goal is to mix IMAP folders with virtual folders on the same folder level (prefix = ""). mail_location = maildir:/data/mail/%d/%u/ # Virtual namespace private { prefix = separator = / location = virtual:/data/mail/%d/%u/virtual } # Default namespace private { separator = / prefix = inbox = yes } With this configuration the folders show up on the same level, but I'm unable to subscribe to them. When I change the prefix back to "virtual/" it works, but folders are still gruoped under "virtual". Funny thing is, when I use a prefix something like "vfolder/", the root folder is no longer greyed out in my MUA (TB3), and I get a "Mailbox doesn't exist: vfolder" error msg if I click on it. BR, Jos

[Dovecot] Best way of dealing with Case-Sensitive Issues in Dovecot
by Mario Antonio 19 Jan '10

19 Jan '10

In order to deal with case-sensitive issues, I am thinking to use the variable %L (adding it to my current configs --as suggested before by other users in this list) in the configuration files in this way: In Dovecot.conf: mail_location = maildir:/vmail/%Ld/%Ln/Maildir:INDEX=/indexes/%Ld/%Ln auth default: username_format: %Lu passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: static args: uid=5000 gid=5000 home=/vmail/%Ld/%Ln allow_all_users=yes In dovecot-sql.conf: password_query = select concat(virtual_users.user, '@', virtual_domains.name) AS user, virtual_users.password as password \ from virtual_users LEFT JOIN virtual_domains ON virtual_users.domain_id=virtual_domains.id \ where virtual_users.user='%Ln' and virtual_domains.name='%Ld' and virtual_users.status = 1 and virtual_domains.status = 1; user_query = SELECT 5000 AS uid,5000 AS gid,'/vmail/%Ld/%Ln' as home, \ concat('*:storage= ', virtual_users.quota_kb) AS quota_rule \ from virtual_users LEFT JOIN virtual_domains ON virtual_users.domain_id=virtual_domains.id \ where virtual_users.user='%Ln' and virtual_domains.name='%Ld' Is this the correct way of assuring lowercase use all over the place? Can I use the variable %L in where sql statements? Regards, Mario Antonio

[Dovecot] expire plugin doesn't find mail location
by Roland Rosenfeld 19 Jan '10

19 Jan '10

Hi! After searching for hours now, I give up and have to ask here. I try to use the expire plugin but it always tries to expire my mails instead of the mails of the user. I read about the "Mail location setting problem (v1.1-v1.2) and configured a "mail" extra field in the userdb, but that doesn't have the effect I want. I have not idea, what I could try out more, so I ask here. My setup is the following: # 1.2.9: /usr/local/dovecot/etc/dovecot.conf # OS: SunOS 5.10 sun4v zfs syslog_facility: local6 protocols: imap pop3 managesieve listen(default): * listen(imap): * listen(pop3): * listen(managesieve): *:2000, *:4190 ssl: no disable_plaintext_auth: no login_dir: /usr/local/dovecot/var/run/dovecot/login login_executable(default): /usr/local/dovecot/libexec/dovecot/imap-login login_executable(imap): /usr/local/dovecot/libexec/dovecot/imap-login login_executable(pop3): /usr/local/dovecot/libexec/dovecot/pop3-login login_executable(managesieve): /usr/local/dovecot/libexec/dovecot/managesieve-login mail_uid: 2001 mail_gid: 2001 mail_location: maildir:/var/mailstore/%2Mn/%n/mail mail_debug: yes mail_executable(default): /usr/local/dovecot/libexec/dovecot/imap mail_executable(imap): /usr/local/dovecot/libexec/dovecot/imap mail_executable(pop3): /usr/local/dovecot/libexec/dovecot/pop3 mail_executable(managesieve): /usr/local/dovecot/libexec/dovecot/managesieve mail_plugins(default): quota imap_quota expire mail_plugins(imap): quota imap_quota expire mail_plugins(pop3): quota expire mail_plugins(managesieve): mail_plugin_dir(default): /usr/local/dovecot/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/dovecot/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/dovecot/lib/dovecot/pop3 mail_plugin_dir(managesieve): /usr/local/dovecot/lib/dovecot/managesieve pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): %v.%u pop3_uidl_format(managesieve): %08Xu%08Xv namespace: type: private separator: / inbox: yes list: yes subscriptions: yes lda: postmaster_address: postmaster(a)netcologne.de hostname: mailstore20.netcologne.de mail_plugins: sieve quota expire auth_socket_path: /usr/local/dovecot/var/run/dovecot/auth-master auth default: master_user_separator: * verbose: yes debug: yes passdb: driver: passwd-file args: /usr/local/dovecot/etc/passwd.master pass: yes master: yes passdb: driver: sql args: /usr/local/dovecot/etc/dovecot-sql.conf userdb: driver: prefetch userdb: driver: sql args: /usr/local/dovecot/etc/dovecot-sql.conf socket: type: listen master: path: /usr/local/dovecot/var/run/dovecot/auth-master mode: 384 user: vmail plugin: quota: maildir expire: INBOX 60 Spam 60 Papierkorb 60 Trash 1 expire_dict: proxy::expire dict: expire: mysql:/usr/local/dovecot/etc/dovecot-dict-expire.conf With the following dovecot-sql.conf: driver = mysql connect = host=localhost dbname=cyrus user=cyrus password=XXXX default_pass_scheme = CRYPT password_query = \ SELECT username, password, concat('*:storage=', quota) AS userdb_quota_rule, '/var/mailstore/%2Mn/%n' as userdb_home, 'maildir:/var/mailstore/%2Mn/%n/mail' as userdb_mail \ FROM passwd WHERE username='%n' user_query = \ SELECT concat('*:storage=', quota) AS quota_rule, '/var/mailstore/%2Mn/%n' as home, 'maildir:/var/mailstore/%2Mn/%n/mail' as mail \ FROM passwd WHERE username='%n' And this is dovecot-dict-expire.conf: connect = host=localhost dbname=dovecot user=dovecot password=XXXXXX map { pattern = shared/expire/$user/$mailbox table = expires value_field = expire_stamp fields { username = $user mailbox = $mailbox } } In user test's Trash folder there are mails that are older than 1 day and in dovecot.expires there is +----------+---------+--------------+ | username | mailbox | expire_stamp | +----------+---------+--------------+ | test | Trash | 1262779049 | +----------+---------+--------------+ But if I run /usr/local/dovecot/sbin/dovecot --exec-mail ext /usr/local/dovecot/libexec/dovecot/expire-tool.sh --test I get the following output: Info: Loading modules from directory: /usr/local/dovecot/lib/dovecot/imap Info: Module loaded: /usr/local/dovecot/lib/dovecot/imap/lib10_quota_plugin.so Info: Module loaded: /usr/local/dovecot/lib/dovecot/imap/lib20_expire_plugin.so Info: Quota root: name= backend=maildir args= Info: expire: pattern=INBOX type=expunge secs=5184000 Info: expire: pattern=Spam type=expunge secs=5184000 Info: expire: pattern=Papierkorb type=expunge secs=5184000 Info: expire: pattern=Trash type=expunge secs=86400 Info: auth input: quota_rule=*:storage=10000 Info: auth input: home=/var/mailstore/09/test Info: auth input: mail=maildir:/var/mailstore/09/test/mail Info: Namespace: type=private, prefix=, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes Info: maildir: data=/var/mailstore/df/rrosenfeld/mail Info: maildir++: root=/var/mailstore/df/rrosenfeld/mail, index=, control=, inbox=/var/mailstore/df/rrosenfeld/mail Info: test/Trash: no messages left Info: test/Spam: stop, expire time in future: Sat Mar 6 12:35:10 2010 As you can see, it uses my username (rrosenfeld) instead of the username "test", whose mailbox should be expired. But while the above it printed to the console I get the following in the logfile: Jan 12 15:33:54 mailstore20 dovecot: [ID 583609 local6.info] dict: mysql: Connected to localhost (dovecot) Jan 12 15:33:54 mailstore20 dovecot: [ID 583609 local6.info] auth(default): master in: USER 1 test service=internal Jan 12 15:33:54 mailstore20 dovecot: [ID 583609 local6.info] auth(default): prefetch(test): passdb didn't return userdb entries, trying the next userdb Jan 12 15:33:54 mailstore20 dovecot: [ID 583609 local6.info] auth-worker(default): sql(test): SELECT concat('*:storage=', quota) AS quota_rule, '/var/mailstore/09/test' as home, 'maildir:/var/mailstore/09/test/mail' as mail FROM passwd WHERE username='test' Jan 12 15:33:54 mailstore20 dovecot: [ID 583609 local6.info] auth-worker(default): mysql: Connected to localhost (cyrus) Jan 12 15:33:54 mailstore20 dovecot: [ID 583609 local6.info] auth(default): master out: USER 1 test quota_rule=*:storage=10000 home=/var/mailstore/09/test mail=maildir:/var/mailstore/09/test/mail As you can see, the auth engine sees the request for the user "test". It also returns the correct home and mail attributes (the above messages were triggered by my expire call!). I tried out to comment out the mail_location from dovecot.conf to make sure that the mail attribute from userdb is used, but this has the effect, that dovecot expire does not know any mail location setting at all and tries some "home" directories and different mail storage formats while my setting mail=maildir:/var/mailstore/09/test/mail from the userdb is completely ignored: Info: Loading modules from directory: /usr/local/dovecot/lib/dovecot/imap Info: Module loaded: /usr/local/dovecot/lib/dovecot/imap/lib10_quota_plugin.so Info: Module loaded: /usr/local/dovecot/lib/dovecot/imap/lib20_expire_plugin.so Info: Quota root: name= backend=maildir args= Info: expire: pattern=INBOX type=expunge secs=5184000 Info: expire: pattern=Spam type=expunge secs=5184000 Info: expire: pattern=Papierkorb type=expunge secs=5184000 Info: expire: pattern=Trash type=expunge secs=86400 Info: auth input: quota_rule=*:storage=10000 Info: auth input: home=/var/mailstore/09/test Info: auth input: mail=maildir:/var/mailstore/09/test/mail Info: Namespace: type=private, prefix=, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes Info: cydir: mailbox location not given Info: cydir: Couldn't create mail storage : Root mail directory not given Info: dbox: mailbox location not given Info: dbox: Couldn't create mail storage : Root mail directory not given Info: maildir: access(/var/mailstore/09/test/Maildir, rwx): failed: No such file or directory Info: maildir: couldn't find root dir Info: maildir: Couldn't create mail storage : Root mail directory not given Info: mbox: root exists (/var/mailstore/09/test/mail) Info: mbox: INBOX: access(/var/mail/test, rw) failed: No such file or directory Info: mbox: INBOX: access(/var/spool/mail/test, rw) failed: No such file or directory Info: mbox: INBOX defaulted to /var/mailstore/09/test/mail/inbox Info: fs: root=/var/mailstore/09/test/mail, index=, control=, inbox=/var/mailstore/09/test/mail/inbox Info: test/Trash: no messages left Info: test/Spam: stop, expire time in future: Sat Mar 6 12:35:10 2010 As you can see, expire tries to access different (default?) mailbox typies instead of simply using maildir:/var/mailstore/09/test/mail as defined in the userdb. So my main problem seems to be, that the mail attribute from the userdb is completely ignored in expire calls. But how do I fix this?

[Dovecot] Dovecot-deliver sometimes fails when message set to discard via sieve
by Steve Wagner 19 Jan '10

19 Jan '10

Hi, sometimes mails that i discard via sieve gets delivered to my inbox and i can not figure out why. So i hope you can give me a hint. My setup is: I use a self compiled dovecot 1.2.4 with installed sieve and managesieve plugin. Incoming mails a processed by Postfix and the delivered to Procmail. Procmail invokes Spamassassin and discard all mails marked as spam. The other mails are passed to Dovecot deliver this way: :0 w | /opt/dovecot/libexec/dovecot/deliver For moving mails to subdirectorys this works always, but not for mails that are discard via Sieve. Examples are: if header :contains "List-Id" "git.vger.kernel.org" { if header :contains "Subject" "[ANNOUNCE]" { fileinto "Announce"; stop; } if header :contains "Subject" "[ANN]" { fileinto "Announce"; stop; } if header :contains "Subject" "[PATCH" { discard; stop; } fileinto "Lists.Git"; stop; } or if header :contains "Organization" "web.de" { discard; stop; } This often works, but sometimes it fails. Procmail reports then that deliver reported an error (but not which) and delivers them to my inbox. There are also no message in dovecots or dovecot delivers log file. Dose anybody have an idea?

[Dovecot] Socket permission 432/384 and dovecot.conf
by Seba 19 Jan '10

19 Jan '10

Sorry for that question but: when you set in dovecot.conf this for example: socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } and you run "dovecot -n" you'll see client: path: /var/spool/postfix/private/auth mode: 432 I'm wondering about the mode "432" - how is this value calculated? Same for the auth/master socket socket - the value ist "384" and in dovecot.conf it's 0600. Thanks for any info. Seba

[Dovecot] Dovecot Proxy and environment variables
by BaQs 19 Jan '10

19 Jan '10

Dear list, First of all, I am French so excuse my bad english. I am currently using dovecot proxy feature, using sql backend. I "proxy" the imap/pop requests to another server, let's say server2. On server2, I use a script to keep up to date a "pop before smtp auth" database. I used mail_executable = /path/to/this/script.sh ... My problem is: the $IP environment variable on server2 is the proxy's IP. How could I give a variable from proxy to server2, or simply get the real client public IP ? Thanks a lot in advance for your answers Pierre. PS: let me also thank very much dovecot developers and community !

[Dovecot] No filelocking at "shared-mailboxes" dictionary?
by Peer Heinlein 19 Jan '10

19 Jan '10

Using imapsync I changed many ACLs on many accounts simultaneously in four concurrent IMAP-sessions. I started with an empty file "shared-mailboxes". But after the sync the file "shared-mailboxes" has been crashed. I found broken lines and I'm missing some entrys. Is it possible that there's no filelocking on that file? I used the ext3 filesystem. That's what shred-mailboxes looks like at the moment: shared/shared-box 1 shared/shared-boxes/user/user1.example.com/user2.example.com 1 .example.com/user5.example.com 1 hared/shared-boxes/user/user6.example.com/user4.example.c2442203233424^? 1 ser/user7.example.com/user2.example.com Peer dovecot -n: # 1.2.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.27.39-0.2-default x86_64 openSUSE 11.1 (x86_64) protocols: imap imaps managesieve ssl_cert_file: /etc/ssl/old.pem ssl_key_file: /etc/ssl/old.pem shutdown_clients: 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(managesieve): /usr/lib/dovecot/managesieve-login login_process_per_connection: no login_max_processes_count: 512 max_mail_processes: 1024 mail_max_userip_connections(default): 40 mail_max_userip_connections(imap): 40 mail_max_userip_connections(managesieve): 10 verbose_proctitle: yes mail_uid: vmail mail_gid: vmail mail_location: maildir:~/Maildir mail_executable(default): /usr/lib/dovecot/imap-usernamenmigration mail_executable(imap): /usr/lib/dovecot/imap-usernamenmigration mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugins(default): quota imap_quota acl imap_acl mail_plugins(imap): quota imap_quota acl imap_acl mail_plugins(managesieve): mail_plugin_dir(default): /usr/lib64/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib64/dovecot/modules/imap mail_plugin_dir(managesieve): /usr/lib64/dovecot/modules/managesieve namespace: type: private separator: / inbox: yes list: yes subscriptions: yes namespace: type: shared separator: / prefix: zz_SHARED_ACCOUNTS/%%u/ location: maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u list: yes lda: postmaster_address: postmaster(a)iea-dpc.org mail_plugins: quota acl sieve mail_plugin_dir: /usr/lib64/dovecot/modules/lda quota_full_tempfail: yes auth default: mechanisms: plain login digest-md5 cram-md5 verbose: yes debug: yes debug_passwords: yes passdb: driver: passwd-file args: /etc/dovecot/userdb userdb: driver: passwd-file args: /etc/dovecot/userdb userdb: driver: static args: uid=5001 gid=5001 socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 432 user: vmail group: vmail plugin: quota: maildir quota_rule: *:storage=102400 acl: vfile acl_shared_dict: file:/var/lib/dovecot/shared-mailboxes sieve: ~/.dovecot.sieve sieve_dir: ~/sieve -- Heinlein Professional Linux Support GmbH Linux: Akademie - Support - Hosting http://www.heinlein-support.de Tel: 030 / 40 50 51 - 0 Fax: 030 / 40 50 51 - 19 Zwangsangaben lt. §35a GmbHG: HRB 93818 B / Amtsgericht Berlin-Charlottenburg, Geschäftsführer: Peer Heinlein -- Sitz: Berlin

[Dovecot] Upgrade path questions
by Thomas M Goerger 18 Jan '10

18 Jan '10

Hi, We are currently running Dovecot v1.1.6 on our servers, and are contemplating an upgrade to 1.2, or 2.0 soon. We are wondering how many organizations are still running a 1.1 version of Dovecot, and if anyone has any thoughts on this transition. Have you upgraded from 1.1 to 1.2? What are your experiences with this? Have you upgraded from 1.1 to 2.0 directly? What are your experiences this way? We are also running an environment with both mbox and maildir formats. How many of you are running similarly, or are running solely maildir or mbox? We're just looking to gather information going forward, and anything you might be able to contribute would be very helpful. Thanks! ************************************************************************* * Tom Goerger - Email/Unix System Administrator * * * * University of Minnesota Email: tmg(a)umn.edu * * Operations, Infrastructure and Architecture Phone: 4-5804 * * Internet Services Office: 626J WBOB * * * *************************************************************************

[Dovecot] unlinking

Quick question. How important are these? Are the errors recoverable and not a big deal, or are they actually a problem? I see a few of these randomly over the course of the day.

[Dovecot] Strange permission problem with Maildir
by tkin1t3asy 18 Jan '10

18 Jan '10

I have this very strange problem with Dovecot spitting out a file permissions error but further testing seems to show it being an inaccurate message. POP3(username): maildir: data ~/Maildir POP3(username): maildir++: root =/home/ssb201/Maildir, index=, control=, inbox=/home/ssb201/Maildir POP3(username): stat(/home/username/Maildir/tmp) failed: Permission denied (euid=500(username) egid=500(username) missing +x perm: /home/username/Maildir) POP3(username): Couldn't open INBOX... as you can see below the permissions are correct: root@host:/home/username# ls -al Maildir/ total 744 drwx------ 8 username username 220 2010-01-13 06:27 . drwxr-xr-x 18 username username 80 2010-01-13 06:14 .. drwx------ 2 username username 108480 2010-01-14 20:56 cur -rw------- 1 username username 65272 2010-01-14 20:56 dovecot.index -rw------- 1 username username 382976 2010-01-14 20:56 dovecot.index.cache -rw------- 1 username username 6836 2010-01-14 20:56 dovecot.index.log -rw------- 1 username username 309472 2010-01-14 20:56 dovecot-uidlist -rw------- 1 username username 8 2010-01-14 20:56 dovecot-uidvalidity -rw------- 1 username username 0 2010-01-14 20:56 dovecot-uidvalidity.4a090e80 drwx------ 2 username username 40 2010-01-14 20:56 new drwx------ 2 username username 40 2010-01-14 20:56 tmp if I rename ~/Maildir to ~/Maildir.orig and let dovecot create a new directory it works fine with no errors. root@host:/home/username# ls -al Maildir total 28 drwx------ 5 username username 220 2010-01-14 21:19 . drwxr-xr-x 19 username username 100 2010-01-14 21:19 .. drwx------ 2 username username 40 2010-01-14 21:19 cur -rw------- 1 username username 16384 2010-01-14 21:19 dovecot.index.cache -rw------- 1 username username 468 2010-01-14 21:19 dovecot.index.log -rw------- 1 username username 70 2010-01-14 21:19 dovecot-uidlist -rw------- 1 username username 8 2010-01-14 21:19 dovecot-uidvalidity -rw------- 1 username username 0 2010-01-14 21:19 dovecot-uidvalidity.4b4f8a6e drwx------ 2 username username 60 2010-01-14 21:19 new drwx------ 2 username username 40 2010-01-14 21:19 tmp If I rename the newly created ~/Maildir to ~/Maildir.new, and rename ~/Maildir.orig to ~/Maildir the original directory works now with no "+x perm" error. This would seem to imply that dovecot is modifying something, somewhere else on the system when it creates the mail directory.

[Dovecot] how-to use dsync to do a 2 ways replication ?
by Eric Belhomme 18 Jan '10

18 Jan '10

Hi, I want to set-up two dovecot imap servers, with active-active replicated maildirs. The goal is to have a hosted public server on Internet, and a private server on my LAN to speed-up local connections. So I compiled dovecot 2.0 beta 1 in order to use dsync utility... Actually my config is pretty simple as I just want to setup a proof of concept before going ahead in this way : (Both servers are Debian Lenny with excatly the same config) mail0:~# /usr/local/dovecot2/sbin/dovecot -n # 2.0.beta1: /etc/dovecot2/dovecot/dovecot.conf # OS: Linux 2.6.26-2-686 i686 Debian 5.0.3 auth_debug = yes auth_verbose = yes login_trusted_networks = 172.16.64.0/18 mail_location = maildir:%h passdb { args = /etc/dovecot/userpasswd deny = no driver = passwd-file } postmaster_address = postmaster(a)example.com service pop3-login { inet_listener { port = 110 } inet_listener { port = 995 ssl = yes } } service imap-login { inet_listener { port = 143 } inet_listener { port = 993 ssl = yes } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = prefetch } userdb { args = /etc/dovecot/userpasswd driver = passwd-file } I logged on the first server with an IMAP client then I copied many email through IMAP, then I launched dsync as root : /usr/local/dovecot2/bin/dsync -v mirror 'ssh eole.it.fr.eve /usr/local/dovecot2/bin/dsync' root(a)eole.it.fr.eve's password: dsync-local(root): Error: Can't create mailbox ssh: Mailbox already exists dsync-local(root): Error: Can't create mailbox aptitude: Mailbox already exists dsync-local(root): Error: Can't create mailbox debtags: Mailbox already exists dsync-local(root): Info: debtags: only in source dsync-local(root): Info: aptitude: only in source dsync-local(root): Info: ssh: only in source dsync-local(root): Info: ssh: only in dest dsync-local(root): Info: aptitude: only in dest dsync-local(root): Info: debtags: only in dest dsync-local(root): Error: Mailbox ssh changed its GUID (cdfc9a2d85154e4b47180000b31a5865 -> 541e9f2850234e4b3a2b0000d0cf7273) dsync-local(root): Error: msg iteration failed: Couldn't open mailbox dsync-remote(root): Error: Can't create mailbox debtags: Mailbox already exists dsync-remote(root): Error: Can't create mailbox aptitude: Mailbox already exists dsync-remote(root): Error: Can't create mailbox ssh: Mailbox already exists dsync-remote(root): Error: Mailbox debtags changed its GUID (501e9f2850234e4b3a2b0000d0cf7273 -> d1fc9a2d85154e4b47180000b31a5865) dsync-remote(root): Error: msg iteration failed: Couldn't open mailbox dsync-remote(root): Error: command MSG-LIST failed dsync-local(root): Error: Mailbox ssh changed its GUID (cdfc9a2d85154e4b47180000b31a5865 -> 541e9f2850234e4b3a2b0000d0cf7273) dsync-local(root): Error: Mailbox aptitude changed its GUID (cffc9a2d85154e4b47180000b31a5865 -> 521e9f2850234e4b3a2b0000d0cf7273) dsync-local(root): Error: Mailbox debtags changed its GUID (d1fc9a2d85154e4b47180000b31a5865 -> 501e9f2850234e4b3a2b0000d0cf7273) dsync-local(root): Error: Mailbox ssh changed its GUID (cdfc9a2d85154e4b47180000b31a5865 -> 541e9f2850234e4b3a2b0000d0cf7273) dsync-local(root): Error: Mailbox aptitude changed its GUID (cffc9a2d85154e4b47180000b31a5865 -> 521e9f2850234e4b3a2b0000d0cf7273) dsync-local(root): Error: Mailbox debtags changed its GUID (d1fc9a2d85154e4b47180000b31a5865 -> 501e9f2850234e4b3a2b0000d0cf7273) mail0:~# dsync-remote(root): Error: Mailbox debtags changed its GUID (501e9f2850234e4b3a2b0000d0cf7273 -> d1fc9a2d85154e4b47180000b31a5865) dsync-remote(root): Error: Mailbox aptitude changed its GUID (521e9f2850234e4b3a2b0000d0cf7273 -> cffc9a2d85154e4b47180000b31a5865) dsync-remote(root): Error: Mailbox ssh changed its GUID (541e9f2850234e4b3a2b0000d0cf7273 -> cdfc9a2d85154e4b47180000b31a5865) dsync-remote(root): Error: Mailbox debtags changed its GUID (501e9f2850234e4b3a2b0000d0cf7273 -> d1fc9a2d85154e4b47180000b31a5865) dsync-remote(root): Error: Mailbox aptitude changed its GUID (521e9f2850234e4b3a2b0000d0cf7273 -> cffc9a2d85154e4b47180000b31a5865) dsync-remote(root): Error: Mailbox ssh changed its GUID (541e9f2850234e4b3a2b0000d0cf7273 -> cdfc9a2d85154e4b47180000b31a5865) It seems dsync tries to use my system user database instead of the /etc/dovecot/userpasswd file ! I found dsync doc on the wiki at http://wiki2.dovecot.org/Tools/dsync but this is not really clear for me... So maybe someone can tell me what's wrong ? Regards, -- Eric Belhomme

[Dovecot] Adding support for a new storage format - plugin?
by Brad Hards 18 Jan '10

18 Jan '10

Hi, I've spent a little bit of time looking at the dovecot source (from the unstable 2.0 development tree), and I think I'm starting to get it together... Background: I'm interested in dovecot to provide IMAP access to an existing database backed server store (http://www.openchange.org for more details). The goal is to provide parallel access using either IMAP or the exchange RPC protocol. If I understand this stuff: * I can potentially provide access to the store using a plugin. It looks like the virtual mailbox plugin is a potential example here. * I may need to also provide an authentication plugin (not sure whether I can just re-use the existing ldap backend - quite possibly a useful option in my scenario) * I probably can't use the existing SQL code, since it uses its own schema. * I may need to provide some locking to ensure things are always in a consistent state for both IMAP and exchange RPC. Comments? Suggestions? Brad

[Dovecot] listen to imap*s* on multiple ports?
by Frank Cusack 17 Jan '10

17 Jan '10

<http://wiki.dovecot.org/QuestionsAndAnswers#Is_it_possible_to_have_Dovecot_…> is out of date. How can I listen to ssl-wrapped IMAP on multiple ports? I need to listen on both 993 (for some stupid clients I have to support that can't do START TLS) and 80 (to get past L3/L4 firewalls). I'd like to do it in dovecot rather than use nc, ipfilter or whatever. -frank

[Dovecot] handling filename of compressed messages
by Leonardo Rodrigues 17 Jan '10

17 Jan '10

i'm running dovecot 1.2.9 and, among other things, i have the zlib plugin enabled. A shell script runs once a day to compresses all not still compressed files on the users maildirs. so far so good, it works fine, there's no problem on that. what i think is not happening 100% correctly is the following: 1) user receives a message 2) BEFORE the compress routine runs, filename is: new/1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207 3) AFTER the compress routine, filename is now: new/1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207.gz 4) user check his mail .... and now the filename is cur/1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207.gz:2,S 5) user replies that mail .... and now the filename is cur/1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207.gz:2,RS i'm aware that dovecot doesnt need the '.gz' extension on the file to recognize that as a gzipped file. Even without the .gz extension, dovecot is correctly reading the file. the '.gz' is not even necessary on the filename and still dovecot can handle it fine. anyway, i would like to suggest dovecot to handle the filename to keep the .gz extension, if that exists. This could help sysadmins to easily identify gzipped files on the maildirs and make anything with them, if that's desired. i would like to see dovecot changing filenames properly and keeping the .gz extension always, for example cur/1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207:2,S.gz instead of cur/1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207.gz:2,S cur/1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207:2,RS.gz instead of cur/1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207.gz:2,RS -- Atenciosamente / Sincerily, Leonardo Rodrigues Solutti Tecnologia http://www.solutti.com.br Minha armadilha de SPAM, NÃO mandem email gertrudes(a)solutti.com.br My SPAMTRAP, do not email it

[Dovecot] shared namespace bug?
by Patrick Kaiser 14 Jan '10

14 Jan '10

Hi, finally i got shared namespace up and running. But for example if user peter.griffin shares his inbox to another user, the LIST "" "*" output on telnet looks like: a02 LIST "" "*" * LIST (\HasNoChildren) "/" "Trash" * LIST (\HasNoChildren) "/" "INBOX" * LIST (\Noselect) "/" "shared/peter.griffi" * LIST (\HasChildren) "/" "shared/peter.griffin" * LIST (\HasNoChildren) "/" "shared/peter.griffinINBOX" a02 OK List completed. To share the inbox I previously run as logged in user peter.griffin a02 SETACL inbox peter.griffin lwxrk If I look in thunderbird, i can see under "share" two folders: peter.griffi and peter.griffin. Have i made something wrong, or is this a bug? Hope someone can help me. thanks, patrick -- Name : Patrick Kaiser Email : patrick.kaiser(a)argonius.de Phone : +49 (178) 8452388 Website : http://www.argonius.de GPG Key : http://www.argonius.de/key.pub

[Dovecot] uw-imap compatability hack?
by Simon Annetts 14 Jan '10

14 Jan '10

Hi all Apologies if this question has already been asked before... I'm migrating from a uw-imap setup where the mail folders were in a subdir mail/ in the users' home directories. All of the clients are configured with 'IMAP server directory' set to mail/ (Thunderbird) and it would be difficult to change this on the clients (there are 1000s of them) I want to use maildir and I have converted the original mbox files in ~mail/ to maildir format. So in ~Maildir/ I now have: cur dovecot.index dovecot.index.cache dovecot.index.log dovecot-uidlist .Drafts new .Sent-Items .Spam subscriptions tmp .Trash if I remove the mail/ setting from 'IMAP server directory' in the client, then everything works as expected and all the folders are visible. With this setting in however, only the inbox is visible and attempts to click on another folder, say Trash result in the client error: Mailbox doesn't exist .mail.Trash I've tried various namespace configurations I found in the namespaces wiki example but none seem to work. What I would really like to happen is for dovecot to ignore this setting supplied by the client and not to prepend .mail onto the folders it is looking for. Is there a clever namespace that will do this for me, or some other setting or symlink trickery? Ultimately I want to support clients that might have both mail/ and nothing set in this box.

Is there any way to tell dovecot to listen for imap/imaps requests on all interfaces on multiple separate ports? For example, can I do this: protocol imap { listen = *:10143 listen = *:143 ssl_listen = *:10993 ssl_listen = *:993 ... } Thanks! Rick
