stemmer or no-stemmer..
by Akash 05 Sep '14

05 Sep '14

Hi, In the documentation of FTS lucene, I need little more clarification about this section: -------------------------------------------------- --with-lucene --with-stemmer The second switch is only required if you have compiled libstemmer yourself or if it's included in the CLucene you are using. -------------------------------------------------- I am totally unsure but as I understand, on Debian testing, the stemmer support for libclucene comes as part of libclucene-contribs1 package (which isn't a required dependency and doesn't get installed if I install dovecot from repos). Please correct me if I am wrong. When I install dovecot-lucene from repos, libclucene-core1 and libstemmer install with it (but no libclucene-contribs1). Does that mean dovecot search has stemmer support? Now I am compiling dovecot and libclucene for Debian stable (which doesn't have latest libs in repos). If I don't compile the contribs part in clucene package but compile dovecot with --with-stemmer, do I get the stemmer support? If I totally opt of this stemmer thing, do I lose anything on search performance? And when you have a no_snowball option, what is the need of libstemmer altogether? Please help me through these confusions.. -Regards, Akash

Migrating from 2.0.x to 2.2
by Jens Dueholm Christensen 05 Sep '14

05 Sep '14

Hi I'm about to migrate a setup with <20 IMAP (but with a few million mails in all) accounts that belong to the same system-user on an older machine running Dovecot 2.0.13 to a new machine running Dovecot 2.2.13 (or possibly newer..). Mails are stored in Maildirs with no special or advanced features (like alternate storage etc etc). Filesystems are prepared for the expected amount of inodes required, and for the time beeing a change to mdbox is seen as an added complexity. One requirement of the migration is that messageID is not changed - mails are referenced by other systems that expect to find individual mails by the ID. Since dsync is incompatible between 2.0<->2.1<->2.2 what is the best way to perform this migration? I was hoping of rsync'ing all Maildirs from the old machine to the new one (including indexes etc etc) and power up Dovecot 2.2.x and see what happens, but is that possible or is there another (and better) way short of installing 2.0.x on the new machine, rsync everything and then upgrade to 2.2.x? Regards, Jens Dueholm Christensen

how to profiling imap process with valgrind
by morrison 05 Sep '14

05 Sep '14

Hi, I want to profile runtime performance of imap and pop3 processes. There processes are forked by dovecot master process. I am wondering if there is a way I can profile these processes with valgrind. I tried "service = /bin/valgrind /bin/imap" but this did not work. Thanks,

SASL LOGIN : connection to server lost with more than 10 simulatneaous postfix smtps
by Ve (HOME) 04 Sep '14

Hi All, I have a problem with SASL authentification from postfix when more than 10 mails is sent from the same user simultaneously Postfix abort connection ( Connection lost to authentication server ). Dovecot log after the postfix error an error about connection lost also ( read EOF ) I don't seem to find a parameter for a maximum of connection for the auth process ( ther's one for imap, pop, .. ) but none for auth.

Trying Dovecot Replication with dsync
by Listas＠Adminlinux 04 Sep '14

04 Sep '14

Hi, I have a failover cluster for mail server with: Ubuntu12.04 + DRBD (for block replication) + Ext4 filesystem + Dovecot-2.0.19-2 with Mdbox It works fine with ~50k accounts. My cluster design: http://adminlinux.com.br/cluster_design.txt I plan to test Dovecot Replication with dsync to build an active/active cluster with load balancing. Can anyone direct me to some literature? A tutorial for example. I'm installing a cluster (for tests) with Ubuntu 14.04 + Ext4 filesystem (without Drbd) + Dovecot-2.2.9-1ubuntu2.1. My conf is in: http://adminlinux.com.br/replication-doveconf.txt I'm following this doc http://wiki2.dovecot.org/Replication but I'm getting some errors: 1) Aug 14 15:39:34 ceph1 dovecot: imap(account=domaintest.com): Error: open(/var/run/dovecot/replication-notify-fifo) failed: Permission denied What is the correct perms for /var/run/dovecot/replication-notify-fifo ?

Insert custom header in Mail logger plugin

03 Sep '14

Is it possible to log a message custom header through Mail logger plugin or other method? It seems that there are a fixed number of info that is configurable via mail_log_fields (http://wiki2.dovecot.org/Plugins/MailLog) .. My custom header is X-VERTICAL-IP-Quarantine-ID and I want a log event like this one: Aug 27 09:48:13 imap dovecot: imap(user@domain): copy from INBOX: box=SPAM, uid=213, *X-VERTICAL-IP-Quarantine-ID=u7cnUqYDPA9a*, msgid=< 0.0.D7.290.1CFC155CE887302.0(a)etm2.com>, size=26481, vsize=26949, from==?UTF-8?Q?Dafiti=20-=20Parceiros?= <aaa@domain>, subject==?UTF-8?Q?Sapatos=20com=2040%OFF?==?UTF-8?Q?!=20Apro?=? =?UTF-8?Q?veite!?= -- Att.

Setup sieve failed
by Christian Vielhauer 03 Sep '14

03 Sep '14

Hi, I try to setup sieve but I have some trouble. Using dovecot 2.2.9 on Ubuntu 14.04.1 LTS. I replaced my correct domain with „domain.tld“. I am able to create sieve scripts using SOGo. The scripts are created in my mailbox. For example in /var/www/kunden/mail/domain.tld/testuser/sieve/sogo.sieve I have the following script and in same ~/sieve folder is a subdirectory available that’s called "tmp“: ~/sieve ~/sieve/tmp require ["vacation"]; if allof ( not exists ["list-help", "list-unsubscribe", "list-subscribe", "list-owner", "list-post", "list-archive", "list-id", "Mailing-List"], not header :comparator "i;ascii-casemap" :is "Precedence" ["list", "bulk", "junk"], not header :comparator "i;ascii-casemap" :matches "To" "Multiple recipients of*" ) {vacation :days 1 :addresses [„testuser(a)domain.tld"] text: This is a vacation test message. Please ignore. . ; } Now I open /var/log/mail.err and I can see the following: Sep 3 17:50:09 mail dovecot: imap(testuser(a)domain.tld): Error: stat(/var/www/kunden/mail/domain.tld/testuser/.dovecot.sieve/tmp) failed: Not a directory I try to create ~/.dovecot.sieve folder, but this file exists and is a symlink. 0 lrwxrwxrwx 1 vmail vmail 16 Sep 3 18:14 .dovecot.sieve -> sieve/sogo.sieve I think I have some miss configuration because i don’t receive any vacation reply when I send mail to my testuser.
