[Dovecot] Migrating mailboxes
by Odhiambo Washington 09 Jan '13

09 Jan '13

Hello everyone and Happy 2013! I have a situation -- the first ever I have come across -- which I don't understand. A friend was/is running Postfix and Dovecot - with default configs - nothing was ever changed :-) [root@mail home]# dovecot --version 0.99.11 Anyway, he had a problem with a user mailbox which I wasn't able to diagnose and fix easily. maillog showed: Jan 9 16:11:29 mail imap-login: Login: userx [::ffff:127.0.0.1] Jan 9 16:11:29 mail imap(userx): file lib.c: line 37 (nearest_power): assertion failed: (num <= ((size_t)1 << (BITS_IN_SIZE_T-1))) Jan 9 16:11:29 mail dovecot: child 25217 (imap) killed with signal 6 Jan 9 16:12:03 mail imap-login: Login: userx [::ffff:127.0.0.1] Jan 9 16:12:03 mail imap(userx): file lib.c: line 37 (nearest_power): assertion failed: (num <= ((size_t)1 << (BITS_IN_SIZE_T-1))) Jan 9 16:12:03 mail dovecot: child 25229 (imap) killed with signal 6 Jan 9 16:13:15 mail pop3-login: Login: userx [::ffff:192.168.0.55] Jan 9 16:13:15 mail pop3(userx): file lib.c: line 37 (nearest_power): assertion failed: (num <= ((size_t)1 << (BITS_IN_SIZE_T-1))) My aim is not to fix the above. I have reconfigured both Postfix and Dovecot to use Maildir now and things are fine (not securitywise, but I don't care about that) for now. However, I'd like to migrate old mail for some users, but I don't know how to go about this, given the mailbox format, which I don't understand: Here is what a typical one looks like: [root@mail home]# ls -al johndoe/mail/.imap/ total 24 drwx------ 6 johndoe users 4096 May 27 2010 . drwx------ 3 johndoe users 4096 May 27 2010 .. drwx------ 2 johndoe users 4096 May 27 2010 Drafts drwx------ 2 johndoe users 4096 Jan 9 15:46 INBOX drwx------ 2 johndoe users 4096 May 27 2010 Sent drwx------ 2 johndoe users 4096 May 27 2010 Trash [root@mail home]# ls -al johndoe/mail/.imap/INBOX/ total 180 drwx------ 2 johndoe users 4096 Jan 9 15:46 . drwx------ 6 johndoe users 4096 May 27 2010 .. -rw------- 1 johndoe users 5 Dec 18 2007 .customflags -rw------- 1 johndoe users 10272 Jan 9 15:46 .imap.index -rw------- 1 johndoe users 132774 Jan 9 11:27 .imap.index.data -rw------- 1 johndoe users 5136 Sep 26 2011 .imap.index.log -rw------- 1 johndoe users 9404 Jan 8 18:44 .imap.index.tree [root@mail home]# ls -al johndoe/mail/.imap/Sent/ total 36 drwx------ 2 johndoe users 4096 May 27 2010 . drwx------ 6 johndoe users 4096 May 27 2010 .. -rw------- 1 johndoe users 5 May 27 2010 .customflags -rw------- 1 johndoe users 1608 May 27 2010 .imap.index -rw------- 1 johndoe users 10264 May 27 2010 .imap.index.data -rw------- 1 johndoe users 2576 May 27 2010 .imap.index.log -rw------- 1 johndoe users 1556 May 27 2010 .imap.index.tree [root@mail home]# ls -al johndoe/mail/.imap/Drafts/ total 36 drwx------ 2 johndoe users 4096 May 27 2010 . drwx------ 6 johndoe users 4096 May 27 2010 .. -rw------- 1 johndoe users 5 May 27 2010 .customflags -rw------- 1 johndoe users 1608 May 27 2010 .imap.index -rw------- 1 johndoe users 10264 May 27 2010 .imap.index.data -rw------- 1 johndoe users 2576 May 27 2010 .imap.index.log -rw------- 1 johndoe users 1556 May 27 2010 .imap.index.tree [root@mail home]# ls -al johndoe/mail/.imap/Trash/ total 44 drwx------ 2 johndoe users 4096 May 27 2010 . drwx------ 6 johndoe users 4096 May 27 2010 .. -rw------- 1 johndoe users 5 May 27 2010 .customflags -rw------- 1 johndoe users 1608 May 27 2010 .imap.index -rw------- 1 johndoe users 17950 May 27 2010 .imap.index.data -rw------- 1 johndoe users 2576 May 27 2010 .imap.index.log -rw------- 1 johndoe users 1556 May 27 2010 .imap.index.tree How can I migrate these mails into /home/johndoe/Maildir/ ??

[Dovecot] Dsync didn't updates automatically
by Breno Moreira 08 Jan '13

08 Jan '13

Hi, I'm trying to use the Dsync cluster feature in a simple setup, without director, but I'm having some troubles. First of all, I want to know if this functionality syncs the mailbox when the user receive a mail or only when the dovecot starts? Reading the Dovecot mailing list and the design description for a dsync-replicated Dovecot cluster, I understood that it should sync every time a new mail arrives, but it isn't happening in my system. So, can I do this update automatically? If yes, why is it not working properly? Maybe is my configuration files or maybe I'm confusing the capability of this feature. I'm using Dovecot 2.1.7 included in the Debian Wheezy, with virtual users in a MySQL database, Moreover, I have the following configuration: mail_plugins = $mail_plugins notify replication service aggregator { # give enough permissions for mail processes fifo_listener replication-notify-fifo { user = vmail #mode = 0666 } unix_listener replication-notify { user = vmail #mode = 0666 } } service replicator { # start replication at startup process_min_avail = 1 } plugin { # host1 replicates to host2 #mail_replica = remote:vmail at 10.127.0.2 # host2 replicates to host1 mail_replica = remote:vmail@10.127.0.5 } dsync_remote_cmd = ssh -l vmail %{host} doveadm dsync-server -u%u -l%{lock_timeout} -n%{namespace} service doveadm { # if you're using a single virtual user, set this to # start ssh as vmail (not root) user = vmail } service config { unix_listener config { user = vmail } } The vmail user has rsa id's in both servers, so it can do ssh connections without asking for password. I appreciate your help. Best Regards, -- --------------------------------------------------------------------- Breno Moreira "I have no idols. I admire work, dedication and competence." Ayrton Senna

[Dovecot] imap: Error: net_connect_unix(/.../auth-master) failed: Invalid argument
by Joan Picanyol i Puig 08 Jan '13

08 Jan '13

Hi, I'm unable to get past the subject error trying to setup dovecot 2.1.10 on FreeBSD 6.4: right after login the server closes the connection (testing with telnet) I've tried manualy chown()ing auth-master to 666, so permission issues should be ruled out. I'm attaching logs, config and excerpt of ktrace -id. I've built a version with debug symbols, but I don't seem to hit a breakpoint in net_connect_unix on lib/network.c What can I look at? tks -- pica

[Dovecot] Access to deleted mails in mdbox storage
by Wolfgang.Friebel＠desy.de 08 Jan '13

08 Jan '13

Hi Timo, we are currently running dovecot 2.1.10 using mdbox storage. Sometimes we get requests from users to restore accidentally deleted mails. If the mails got deleted before a backup was made, such mails could of course not be restored from backup. One option to help users in this respect would be to use the lazy expunge plugin. On the other hand I have seen, that the deleted mails stay intact in the mdbox storage until a doveadm purge has been performed. Therefore without using the plugin it is in principle possible to get access to any deleted mails. As in our case the expunge runs once a week while the backup is done daily we can basically recover all mails ever received. My question: doveadm has currently no command similar to doveadm search or fetch to get to deleted mails. Would it be useful to have such a command? As a proof of concept I wrote a little script to mimic the doveadm fetch as closely as possible given the limited amount of information in the mdbox/storage/m.* files and could indeed get access to deleted mails. Do you regard such a procedure (within doveadm) useful or would you recommend nevertheless using the lazy expunge plugin? I am aware of the fact that this is a solution for mdbox storage only. -- Wolfgang Friebel Deutsches Elektronen-Synchrotron DESY Phone/Fax: +49 33762 77372/216 Platanenallee 6 Mail: Wolfgang.Friebel AT desy.de D-15738 Zeuthen Germany

[Dovecot] 2 node dovecot
by Lazy 08 Jan '13

08 Jan '13

Hi, We run dovecot 2.1 on 2 nodes with shared nfs storage. Index files are kept on local disk. Second node is usually used only for email snapshots access. If primary node fails it is configured to take place of the primary imap server. Snapshots are additional namespaces with mail from various points in time. We need a way to easly copy multiple messages from snapshots to current mailboxes. It would be best to make current mailbox available as another namespace so one would simply copy messages from one folder to another. Is it safe ? There will be times when given user is writing to the same nfs based Maildir mailbox from 2 nodes both of them having separate index files. What will happen if already present message gets copied back from the snapshot ? Regards, Michał Grzędzicki

[Dovecot] Director and forwarding LDAP user as Master user
by Alexandr Sabitov 08 Jan '13

08 Jan '13

Hello guys, Would you be able to help me with this little issue. I bet someone has the same config so if you can copy-paste it I will very appreciate it. So main idea is to enable Dovecot director to authenticate a LDAP user with plain or encrypted password and send the user to back-end Dovecot server after the authentication. According to Wiki it is only possible if we use the master user to communicate to the back-end server. On the back-end Dovecot server it is working fine, I can log in as normal user/user_password or as user*masteruser/master_password. The back-end config is: auth_master_user_separator = * passdb { driver = passwd-file args = /usr/local/dovecot/etc/dovecot/passwd.masterusers master = yes pass = yes } passdb { driver = ldap args = /usr/local/dovecot/etc/dovecot/dovecot-ldap.conf.ext } userdb { driver = ldap args = /usr/local/dovecot/etc/dovecot/dovecot-ldap.conf.ext } Now front-end: how to get director forward the user to the back-end after authentication on the director? With my director config the user stays on the director all the time: passdb { driver = static args = proxy=y master=masteruser pass=master_password destuser=%u*masteruser } passdb { driver = ldap args = /usr/local/dovecot/etc/dovecot/dovecot-ldap.conf.ext } userdb { driver = ldap args = /usr/local/dovecot/etc/dovecot/dovecot-ldap.conf.ext } The only way to forward the user is to setup nopassword=y in args of static passdb but in that case the user will be authenticated on the backend but not on the director... What do I missing ? Please help me Best Regards, Alexandr Sabitov
