[Dovecot] dovecot and cacti (snmp ?)
by mancyborg＠gmail.com 10 Jan '13

10 Jan '13

Hi All, I've put online a postfix+dovecot+mysql+roundcube server that will grow till serving around 1500 accounts. I've installed the usual cacti graphs, plus the beautiful percona suite for mysql's cacti plus some graphs for iops and iostat. I was lurking around for the best solution to graph dovecot usage, the most detailed possible, in order to prevent and foresee problems. I'm finding sparse results, I'm not sure which one is the most current / complete. Do you have any suggestions ? Thank you very much for supporting, regards and have a nice day, Mike

[Dovecot] unknown users
by Averlon 10 Jan '13

10 Jan '13

Hi, can anyone tell me where these "unknown users" come from. As far as I see the fact, dovecot is asked by postfix to look for the password of the recipient-user (why ever). +++ Jan 7 19:43:09 f42252se postfix/smtpd[14625]: initializing the server-side TLS

[Dovecot] problems with sieve
by Carsten Laun-De Lellis 10 Jan '13

10 Jan '13

Hi all I am running a simple mail server on ubuntu 12.04LTS with postfix 2.9.3 and dovecot 2.1.10. Since this morning sieve doesn't work anymore. I changed the sieve script forth and back but sieve is not working. I also replaced the sieve file with the backup, but no success. But I can't any error messages in the log files indicating any problem with sieve. The only thing I found is: Jan 10 00:03:26 vmd187 dovecot: lda(carsten.delellis(a)delellis.net): sieve: msgid=<12155505.mmailer335539222(a)fritz.box>: stored mail into mailbox 'Fritz!Box' -- with working sieve Jan 10 13:52:29 vmd187 dovecot: lda(carsten.delellis(a)delellis.net): msgid=<1898328495.2554803.1357821905269.JavaMail.app(a)ela4-app2316.prod>: saved mail to INBOX -- with sieve not working As you can see that after dovecot: lda(carsten.delellis(a)delellis.net): the sieve tag is missing. I have also attached my settings from 90-sieve.conf from dovecot configuration. ## ## Settings for the Sieve interpreter ## # Do not forget to enable the Sieve plugin in 15-lda.conf and 20-lmtp.conf # by adding it to the respective mail_plugins= settings. plugin { # The path to the user's main active script. # sieve = ~/.dovecot.sieve sieve = /vmail/%d/%n/dovecot.sieve # A path to a global sieve script file, which gets executed ONLY # if user's private Sieve script doesn't exist.

[Dovecot] Confused about "Authentication Mechanism" and "Password Schemes"
by Thomas Pries 10 Jan '13

10 Jan '13

Hi, I am currently setting up a Mailserver and decided to use Dovecot as IMAP/POP3-Server. I read the wiki an thought about how to transmit and store the passwords (I want to use a MySQL-database). I want to use encrypted transmission and encrypted storage. The wiki says: "If you want to use only one non-plaintext mechanism, you can store the passwords using the mechanism's own password scheme. " Ok, one secure mechanism is acceptable in my scenario and the wiki gives a list of supported authentication mechanisms and a list of supported password schemes. But I am missing the relation between the two lists, which mechanism expects which storage scheme? Did I overlooked any easy answer (other then "read the RFCs"). Best Regards Thomas

[Dovecot] v2.2.beta1 released
by Timo Sirainen 10 Jan '13

10 Jan '13

http://dovecot.org/releases/2.2/beta/dovecot-2.2.beta1.tar.gz http://dovecot.org/releases/2.2/beta/dovecot-2.2.beta1.tar.gz.sig Lots of fixes since 2.2.alpha1, especially related to dsync. Also dsync now supports syncing private message flags when INDEXPVT is used. Here's again the list of all the major changes in v2.2: * When creating home directories, the permissions are copied from the parent directory if it has setgid-bit set. For full details, see http://wiki2.dovecot.org/SharedMailboxes/Permissions * "doveadm auth" command was renamed to "doveadm auth test" * IMAP: ID command now advertises server name as Dovecot by default. It was already trivial to guess this from command replies. * dovecot.index.cache files can be safely accessed only by v2.1.11+. Older versions may think they're corrupted and delete them. + Implemented IMAP MOVE and BINARY extensions + Implemented IMAP CATENATE, URLAUTH and URLAUTH=BINARY extensions (by Stephan Bosch). + Implemented IMAP NOTIFY extension. Requires mailbox_list_index=yes to be enabled. + Redesigned and rewritten dsync. The new design makes the syncing faster, more reliable and more featureful. The new dsync protocol isn't backwards compatible with old dsync versions (but is designed to be forwards compatible with future versions). + All mailbox formats now support per-user message flags for shared mailboxes by using a private index. It can be enabled by adding :INDEXPVT=<path> to mail location. This should be used instead of :INDEX also for Maildir/mbox to improve performance. + Improved mailbox list indexes. They should be usable now, although still disabled by default. + Added LAYOUT=index. The mailbox directories are created using their GUIDs in the filesystem, while the actual GUID <-> name mapping exists only in the index. + LMTP proxy: Implemented XCLIENT extension for passing remote IP address through proxy.

'Father' of the IMAP protocol. Died Dec 28. http://en.wikipedia.org/wiki/Mark_Crispin Had a TOPS-20 in his basement that did a great job of keeping the house warm in the cool months (I remember one BAR bof where he extoled the benefits of this form of home heating).

[Dovecot] Squat FTS plugin not kicking in
by Frerich Raabe 09 Jan '13

09 Jan '13

Hi, I'm running Dovecot 2.1.12 on FreeBSD. I configured Dovecot to use the Squat plugin to provide faster full-text searches. The output of 'dovecot -n' is attached to this mail. However, I just noticed that this plugin doesn't seem to kick in. A raw telnet session seems to confirm this: [..] . SEARCH BODY abcdefg * OK Searched 57% of the mailbox, ETA 0:06 * SEARCH 3425 6254 14710 . OK Search completed (17.262 secs). . SEARCH BODY abcdefg * OK Searched 63% of the mailbox, ETA 0:05 * SEARCH 3425 6254 14710 . OK Search completed (18.651 secs).

[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
