Replication: "cross-updates" of mail meta-data
by Andre Nathan 11 Jun '15

11 Jun '15

Hello I have a two-server dovecot setup using replication. Each server runs two dovecot instances, one for director and another for the backend. Initially I set up a single server, got it all working, then rsync'd the data and index partitions to the new one and started the clusters (I used rsync as a way to speed-up dovecot's initial replication). Both servers listen on a virtual IP addresses load-balanced by IPVS as well as their own IP addresses. When I started dovecot in the second server, users started reporting that some of their messages were missing. I noticed that while the mail data seemed to be up to date in server1, it wasn't in server2; however, the indexes were being updated in server2 but not in server1. For example, "doveadm quota get -u some-user" would report the wrong value in server1 and the right value in server2, while a "du" would show that only server1 actually had the most up-to-date data. At the moment I had to take down server2, because as soon as dovecot is running in it, users start reporting missing messages again. To solve that problem, a "doveadm force-resync" in server1 isn't enough. I either rsync the index files from server2 or remove the indexes in server1 before the force-resync, which then works. Has anyone ever saw anything similar to this? Any help would be much appreciated. I'm running Ubuntu 14.04 with dovecot 2.2.15 with the configurations below: === Backend instance === # dovecot -n # 2.2.15: /etc/dovecot/dovecot.conf # OS: Linux 3.16.0-37-generic x86_64 Ubuntu 14.04.2 LTS auth_master_user_separator = * auth_mechanisms = plain login auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@= auth_worker_max_count = 10 disable_plaintext_auth = no doveadm_password = secret doveadm_port = 12345 listen = server1.mydomain.com mail_fsync = never mail_gid = dovemail mail_plugins = " notify replication quota" mail_uid = dovemail managesieve_sieve_capability = fileinto reject envelope vacation subaddress comparator-i;ascii-numeric relational regex copy include vacation-seconds imapflags notify namespace { inbox = yes location = mailbox SPAM { auto = subscribe } prefix = separator = / type = private } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } passdb { args = /etc/dovecot/dovecot-sql-master.conf.ext driver = sql master = yes pass = yes } plugin { mail_replica = tcp:192.168.0.2:12345 #

Error starting 1.0.15 with SSL_DISABLE=No

When starting Dovecot 1.0.15 after building it from source using the standard procedure, I receive the following message when starting, even though SLL_DISABLE=No: Error: SSL support not compiled in but ssl_disable=no Fatal: Invalid configuration in /usr/local/etc/dovecot.conf How is SSL support configured and built in? I know it has something to do with the --SSL_CFLAGS flag.

Order of keys
by Steve Matzura 10 Jun '15

10 Jun '15

I hope I'm asking this on the right list, in the right place. I go through this every three years and for whatever reason keep forgetting to record how this works! In the Dovecot config, there are two places to define SSL certificates--ssl_cert_file and ssl_key_file. My question is this: Which two of the three files--the certifying authority, the signed certificate for the specific system, and the private certificate file--are combined to create the file that goes with ssl_cert_file? Since there are six possible permutations to answer this question (because order of files matters), which two go with ssl_crt_file and in what order? I have a private certificate file, the certifying authority's .CRT file, and the certifying authority's signed .PEM file which contains the system's certified certificate. Thanks in advance.

can't enable sieve on ubuntu trusty

I try to create a sieve rule on a Ubuntu server ( managed by i-mscp) For this rule i need the editheader extension. I edited /etc/dovecot/conf.d/90-sieve.conf and added the following: plugin { #sieve_extensions = +notify +imapflags sieve_extensions = +editheader ....

Dovecot mbox & other programs
by Pali Rohár 09 Jun '15

09 Jun '15

Hello, I want to use dovecot as imap server with mbox storage format (described at [1]) but I also want to access (and modify!) those mbox files which are stored on server (and used by dovecot). What is correct way to read those mboxes? From wiki page [1] I read that I should ignore first message in mbox (which contains X-IMAPbase header) and mbox file is in mboxcl2 format. And what is correct way to modify that mbox file (which is used by dovecot imap)? I would like to configure mutt on server to directly access those mbox mailboxes without need to use imap protocol (over localhost). It is possible without any data/message damage?

special_use \Archive not working with some foldernames
by Hajo Locke 09 Jun '15

09 Jun '15

Hello list, i use dovecot 2.2.18 compiled on my own and want to report an odd behaviour when using a folder for special_use \Archive. In my case it is not working when using some special foldernames (mbox). I compared to version 2.2.15 which i found pre-packaged on launchpad.net, same behaviour. All other special_use Folder work like expected. My situation: We authenticate users using mysql-db. also we allow users to store individuell special_use settings in db. this is a way which was recommended by this mailinglist some years ago. we use a password_query like this: password_query = SELECT `inbox` as `user`, `password`, `home` as userdb_home, `uid` AS userdb_uid, `gid` AS userdb_gid, `userdb_import` AS userdb_userdb_import FROM `mail_users` WHERE `login` = '%u' AND `active`='Y' typical column in db looks like this: | username | cryptedpass | path | inboxname | uid | gid | Y | namespace/inbox/mailbox=Sent namespace/inbox/mailbox/Sent/name=Gesendet namespace/inbox/mailbox/Sent/auto=subscribe namespace/inbox/mailbox/Sent/special_use=\Sent namespace/inbox/mailbox=Drafts namespace/inbox/mailbox/Drafts/name=EntwÃ¼rfe namespace/inbox/mailbox/Drafts/auto=subscribe namespace/inbox/mailbox/Drafts/special_use=\Drafts namespace/inbox/mailbox=Trash namespace/inbox/mailbox/Trash/name=Papierkorb namespace/inbox/mailbox/Trash/auto=subscribe namespace/inbox/mailbox/Trash/special_use=\Trash namespace/inbox/mailbox=Junk namespace/inbox/mailbox/Junk/name=Spam namespace/inbox/mailbox/Junk/auto=subscribe namespace/inbox/mailbox/Junk/special_use=\Junk namespace/inbox/mailbox=Archives namespace/inbox/mailbox/Archives/name=Archiv namespace/inbox/mailbox/Archives/auto=subscribe namespace/inbox/mailbox/Archives/special_use=\Archive | Now i noticed that in this case the folder Archiv was not binded to special_use \Archive: * LIST (\NoInferiors \UnMarked \Junk) "/" Spam * LIST (\NoInferiors \UnMarked \Drafts) "/" Entw&APw-rfe * LIST (\NoInferiors \UnMarked \Sent) "/" Gesendet * LIST (\NoInferiors \UnMarked \Trash) "/" Papierkorb * LIST (\NoInferiors \UnMarked) "/" Archiv * LIST (\HasNoChildren) "/" INBOX If i change the name of folder which is binded to special_use \Archive its working again, no other changes: * LIST (\NoInferiors \UnMarked \Archive) "/" Archiviu or a shorter one: * LIST (\HasNoChildren \Archive) "/" Arc It works in most cases, it is not working if i have chosen name "Archiv". It seems also that autocreating of folder is not working if name is "Archiv". I activated the debug settings but was not helpful. Looks the same in all cases: Debug: Added userdb setting: namespace/inbox/mailbox=Archives Debug: Added userdb setting: namespace/inbox/mailbox/Archives/auto=subscribe Debug: Added userdb setting: namespace/inbox/mailbox/Archives/name=Arc Debug: Added userdb setting: namespace/inbox/mailbox/Archives/special_use=\Archive or: Debug: Added userdb setting: namespace/inbox/mailbox=Archives Debug: Added userdb setting: namespace/inbox/mailbox/Archives/auto=subscribe Debug: Added userdb setting: namespace/inbox/mailbox/Archives/name=Archiviu Debug: Added userdb setting: namespace/inbox/mailbox/Archives/special_use=\Archive or the not working one: Debug: Added userdb setting: namespace/inbox/mailbox=Archives Debug: Added userdb setting: namespace/inbox/mailbox/Archives/auto=subscribe Debug: Added userdb setting: namespace/inbox/mailbox/Archives/name=Archiv Debug: Added userdb setting: namespace/inbox/mailbox/Archives/special_use=\Archive I have no idea what is going wrong here. I have no further hints in my logs. What to do now? Any ideas? Thanks, Hajo

Backup performance may be another big win for Maildir, especially for incremental backups.

Dovecot mailbox indices are self-healing: indices should be rengenerated automatically when the mailbox is out of sync with regards to the indices. There may be a few complaints in the mail logs about it (e.g. UIDVALIDITY changes), but they are mostly harmless. Joseph Tam <jtam.home(a)gmail.com>
