[Dovecot] Best setup for performance and fault tolerance
by Donny Brooks 30 Nov '11

30 Nov '11

Hello all. I am in need of some guidance. First a little background. Currently our mail server is on physical hardware (Dell server with 2x 2.8GHz Xeon w/ 4GB ram, raid5 array, single gigabit nic) running on Fedora 11 and postfix-2.5.6-3.fc11.x86_64 with dovecot-1.2.11-3.fc11.x86_64. Mailstore is via Maildir format that was converted from mbox about a year ago. This same machine is also our PDC with samba, Master LDAP, slave MySQL replication, primary DNS, and home server for about 20 users. We have approximately 200 end users that have mailboxes on the server ranging from 1KB to 20GB in size. Total mail store is currently at 300GB. About 75 of the users are currently POP access and their mail will be moved to the server soon and setup as IMAP. This is calculated to add roughly another 150GB of mail for a total of 450GB mail store. Being a state agency we have to keep the mail indefinitely for public record reasons. We use a mixture of Thunderbird as an IMAP client and SOGo for web access. Now to the problem: Recently we have been having super slow access to the mail server. Turns out the load was insanely high partially due to the samba home server portion, which is being moved off as we speak, and the other part is due to people searching their mail. Just yesterday one of our users nearly brought the entire agency to its knees by performing a search on her 8GB of mail via IMAP. Since the server is old in both hardware and software I have been tasked with moving it to newer hardware and a newer OS. We currently have 3 virtual servers running Xen and a SAN. The new setup will be placed in the virtual environment. I will probably run Fedora 16 as the OS but am open to Centos, Fedora, or Ubuntu. Now to the question: What is the best way to setup Dovecot so that it is tuned for performance and high available? We have been running with this single point of failure for years so as long as we are moving the mail server we might as well build in some redundancy. To solve the searching problem I thought of maybe setting up some type of indexing. I do kind of want to break the various services out on to separate virtual machines for a little more fault tolerance, but that is not totally necessary. What do you think of things like iRedmail? I see it's usefulness but the not being able to separate services kind of defeats the purpose, plus I want to setup a high available MySQL cluster and possibly OpenLDAP or 389 cluster so iRedMail may not be the best solution. Sorry for the long email but I am trying to get all the information out there at once so it will help get more directed responses in the shortest amount of time. I look forward to any and all input on this matter -- Donny B MDAH

[Dovecot] squat fts not working on 2.1rc1
by Metro Domain Admin 28 Nov '11

28 Nov '11

Hello, I tried to upgrade from 2.0.15 to 2.1.rc1 over the weekend but ran into some problems with squat. My two largest mailboxes were corrupted, producing this error: Nov 27 17:38:12 kerio1 dovecot[42860]: imap(bigmailbox): Error: Corrupted squat uidlist file /var/mail/metro-email.com/bigmailbox/mdbox/mailboxes/INBOX/dbox-Mails/dovecot.index.search.uids: wrong indexid There is a good chance that I had shot my own foot, by forgetting to update postfix's dovecot-lda reference to the new instance. I had also enabled an inet based LMTP listener, although it is not being used yet. Even using non-corrupted indexes, it seemed that FTS was not being used. A basic search such as this one took many minutes to complete: doveadm search -u jsample mailbox INBOX body eps I found messages like this in mail.log after performing the search: Nov 27 18:21:39 kerio1 dovecot[42860]: indexer-worker(jsample): Indexed 0 messages in Drafts Nov 27 18:21:39 kerio1 dovecot[42860]: indexer-worker(jsample): Indexed 0 messages in INBOX When I rolled back to 2.0.15, the same search returned almost immediately. The larger mailboxes went quickly again, but only after they had a chance to rebuild. A few other notes about our configuration: We are on PPC, with the stats service disabled (because of kqueue issue discussed earlier). I made some minor changes in my config since the previous installed version (diff below). mail_location override is in place for all users via password file, e.g.: userdb_mail=mdbox:/var/mail/metro-email.com/jsample/mdbox Thanks, Tony kerio1:~ metroadmin$ /opt/dovecot-2.1.rc1/bin/doveconf -n -c /opt/dovecot-2.1.rc1/etc/dovecot/dovecot.conf # 2.1.rc1: /opt/dovecot-2.1.rc1/etc/dovecot/dovecot.conf # OS: Darwin 9.8.0 Power Macintosh auth_cache_negative_ttl = 0 auth_cache_size = 1 M auth_mechanisms = plain login lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes lmtp_proxy = yes mail_location = maildir:%h mail_plugins = fts fts_squat mail_log notify mail_privileged_group = mail maildir_very_dirty_syncs = yes managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave editheader mdbox_rotate_size = 10 M namespace { inbox = yes location = prefix = separator = / } passdb { args = scheme=CRYPT username_format=%u /opt/dovecot-2.1.rc1/etc/dovecot/users driver = passwd-file } plugin { fts = squat mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = uid box msgid size from subject sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } postmaster_address = postmaster(a)metro-email.com protocols = imap lmtp service auth { unix_listener /var/spool/postfix/private/auth { group = _postfix mode = 0660 user = _postfix } unix_listener auth-userdb { group = mail mode = 0660 user = metroadmin } } service imap { executable = imap postlogin } service lmtp { inet_listener lmtp { address = 192.168.20.10 127.0.0.1 port = 24 } } service postlogin { executable = script-login rawlog -t } service stats { fifo_listener stats-mail { mode = 00 } } ssl_cert = </opt/local/apache2/conf/ssl_startcom/server.crt ssl_key = </opt/local/apache2/conf/ssl_startcom/server.key userdb { args = username_format=%u /opt/dovecot-2.1.rc1/etc/dovecot/users driver = passwd-file } verbose_proctitle = yes protocol imap { mail_max_userip_connections = 16 } Here is a diff between the current/working and attempted configs: kerio1:~ metroadmin$ diff k1.curr k1.new2 1c1 < # 2.0.15: /opt/dovecot-2.0.15/etc/dovecot/dovecot.conf --- > # 2.1.rc1: /opt/dovecot-2.1.rc1/etc/dovecot/dovecot.conf 9a10 > lmtp_proxy = yes 15c16 < managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave --- > managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave editheader 24c25 < args = scheme=CRYPT username_format=%u /opt/dovecot-2.0.15/etc/dovecot/users --- > args = scheme=CRYPT username_format=%u /opt/dovecot-2.1.rc1/etc/dovecot/users 50a52,57 > service lmtp { > inet_listener lmtp { > address = 192.168.20.10 127.0.0.1 > port = 24 > } > } 53a61,65 > service stats { > fifo_listener stats-mail { > mode = 00 > } > } 57c69 < args = username_format=%u /opt/dovecot-2.0.15/etc/dovecot/users --- > args = username_format=%u /opt/dovecot-2.1.rc1/etc/dovecot/users kerio1:~ metroadmin$

[Dovecot] Which FTS to use!
by Henrique Santos Fernandes 27 Nov '11

27 Nov '11

Hello, i am currently using squat dovecot, but some users that have lots os emails ( 1GB ) are complaining about speed. Iam using dovecot 2.0.13 on debian 6 my squat conf is plugin { fts = squat fts_squat = partial=4 full=5 } I am thinking in maybe start to use Solr, so any one can help me with an decision? I am probably gonna update dovecot to 2.1 next year. and them maybe change the FTS plugin. This year i will get 10k disk only to store the dovecot index, rigth now they are saved on the same storage that the mails are and also change the "full" parameter to something like 10 or 15 I know i will use more disk space for it, but it will make a lot of differences right? it will match the message without the need of opening it for any search smaller than 10 character i guess. But this will be enough? or Solr or Lucene still better? Anyway, i am not current updating the indexes automatic, but i am planing on it, just not sure what is better, the command doveadm index or doveadm search... with one is better to do the task? Thanks! []'sf.rique

[Dovecot] Seen flag getting lost
by Edgar Fuß 26 Nov '11

26 Nov '11

We have two dovecot 1.2 instances sharing Maildirs on NFS. Indexes are local to the individual servers. Occasionally (no idea how to trigger this), the Seen flag gets lost on some messages. I've verified that actually the ``S'' is missing from the filename. I suspect something like server A caching the flags, server B setting Seen, and then server A flushing its cache for another change so overwriting what B changed. Any ideas short of switching to 2.0?

[Dovecot] v2.1.rc1 released
by Timo Sirainen 25 Nov '11

25 Nov '11

http://dovecot.org/releases/2.1/rc/dovecot-2.1.rc1.tar.gz http://dovecot.org/releases/2.1/rc/dovecot-2.1.rc1.tar.gz.sig I'll probably release v2.1.0 pretty soon, unless people report some new bugs. I know v2.1 is already being used to serve mails to tens (or hundreds?) of thousands of users, so it should be pretty stable. Most of the changes since v2.1.beta1 have been for rather small issues. Many of the fixed bugs exist also in v2.0, but since they are so minor I didn't bother backporting the fixes. As new features since v2.1.beta1 there are the things I did also for v2.0.16, and: * ssl_client_cert/key: Proxying can now send SSL certificate to backend server * ssl_crypto_device for enabling hardware encryption * SCRAM-SHA-1 authentication mechanism support by Florian Zeitz * passdb/userdb checkpassword: Export all auth %variables to AUTH_* environment. * maildir_broken_filename_sizes setting for people upgrading from other maildir servers that wrote tons of broken S=<size> values And as a reminder, here are the biggest new things since v2.0: * Plugins now use UTF-8 mailbox names rather than mUTF-7: acl, autocreate, expire, trash, virtual * auth_username_format default changed to %Lu. If you really want case sensitive usernames, set it back to empty. * Solr full text search backend changed to use mailbox GUIDs instead of mailbox names, requiring reindexing everything. solr_old backend can be used with old indexes to avoid reindexing, but it doesn't support some newer features. + imapc (= IMAP client) storage allows using a remote IMAP server to be used as storage. This allows using Dovecot as a smart (caching) proxy or using dsync to do migration from remote IMAP server. + Mailbox indexing via queuing indexer service (required for Lucene) + Lucene full text search (FTS) backend rewritten with support for different languages + FTS finally supports "OR" search operation + FTS supports indexing attachments via external programs + IMAP FUZZY extension, supported by Lucene and Solr FTS backends + Mailbox list indexes + Statistics tracking via stats service. Exported via doveadm stats. + Autocreate plugin creates/subscribes mailboxes physically only when the mailbox is opened for the first time. Mailbox listing shows the autocreated mailboxes even if they don't physically exist. + Password and user databases now support default_fields and override_fields settings to specify template defaults/overrides. - listescape plugin works perfectly now

[Dovecot] How to create home directories for virtual users?
by Olli Räisänen 25 Nov '11

25 Nov '11

Hello, I,m using Dovecot 1.2.9, now finishing a migration from Courier IMAP. Documentation (http://wiki.dovecot.org/VirtualUsers/Home) says that home directory should not be the same as mail directory. When I create new user accounts with PostfixAdmin the mail directory is not a problem but is there some smart way to create the home directory as well (locating it for instance in '/srv/vmail/%d/%n/home')? Regards, Olli

[Dovecot] Problem with lmtp proxy
by Miguel Tormo 24 Nov '11

24 Nov '11

Hello everyone, I have set up postfix to deliver mails to dovecot (2.0.16) using LMTP. On the other hand, I've successfully configured the IMAP proxy setting in dovecot in order to be able to distribute mailboxes among different servers. I wanted to do the same proxy at LMTP level, but it's not working. If I put lmtp_proxy = no, then everything works ok (assuming the mailbox is local), but when I set lmtp_proxy = yes then the user is not found when deliverying the message via LMTP, so the mail remains in the postfix queue. Users are validated through active directory. However, this AD hasn't the SFU installed, thus its LDAP schema doesn't provide me with the required uid, gid, etc. To solve this, I have winbind configured in the system, so I'm doing this: - To validate users *and* be able to set the proxy extra fields, I use ldap as "passdb" (I believe it's not possible to use proxies with PAM). I'm using some LDAP field to store the host that has the user's mailbox. - In order to get the user account data that is not available in the AD, I use passwd as "userdb". I know that when using LMTP with proxy, a passdb needs to be configured. I assume this is needed for the service to lookup for the appropriate host to send the message. So, initially I set ldap as the passdb for LMTP, but just because it didn't work I put both ldap and passwd, and even a userdb (passwd), but the problems remain the same. Anyway the ldap should be the right one as it is there where I have the host information for each user. I think I'm missing something but I can't find what it is. To summarize: with lmtp_proxy = no it does work, with lmtp_proxy = yes it doesn't. Thank you for your help!
