[Dovecot] slow dict lookups?
by Anand Kumria 12 Sep '13

12 Sep '13

Hi, I am beginning to see many entries like: Sep 10 21:32:06 mail1 dovecot: imap(user1(a)example1.com): Warning: read(/var/run/dovecot/dict): dict lookup took 20 seconds Sep 10 21:32:11 mail1 dovecot: imap(user2(a)example2.com): Warning: read(/var/run/dovecot/dict): dict lookup took 25 seconds Sep 10 21:32:16 mail1 dovecot: imap(user3(a)example3.com): Warning: read(/var/run/dovecot/dict): dict lookup took 30 seconds Sep 10 21:32:21 mail1 dovecot: imap(user3(a)example3.com): Error: read(/var/run/dovecot/dict) failed: Timeout after 30 seconds Sep 10 21:32:21 mail1 dovecot: imap(user1(a)example1.com): Warning: read(/var/run/dovecot/dict): dict lookup took 25 seconds Sep 10 21:32:21 mail1 dovecot: imap(user4(a)example2.com): Warning: read(/var/run/dovecot/dict): dict lookup took 24 seconds Sep 10 21:32:26 mail1 dovecot: imap(user5(a)example2.com): Warning: read(/var/run/dovecot/dict): dict lookup took 29 seconds What is the best way to look into making dict lookups faster? In my case the dict is use for user / domain quotas and is looked up via Postgres (on another host). Is there further logging I can enable to see where the problem is? Thanks, Anand

[Dovecot] Double Maildir folders.
by Bruce Markey 12 Sep '13

12 Sep '13

Somehow in setting up quotas and sieve I somehow doubled my maildir. I noticed that when I logged into my webmail I didn't see the folders I created. I went to the actual location and noticed this. Mail location is set correctly in 10-mail.conf mail_location = maildir:/var/vmail/%d/%n/Maildir So I went to /var/vmail/domain/user and saw: drwx------ 8 vmail vmail 4.0K Sep 11 22:08 . drwx------ 4 vmail vmail 4.0K Sep 10 18:40 .. drwx------ 5 vmail vmail 4.0K Sep 11 22:04 .Sent lrwxrwxrwx 1 vmail vmail 21 Sep 11 15:44 .dovecot.sieve -> sieve/roundcube.sieve -rw------- 1 vmail vmail 199 Sep 11 15:45 .dovecot.svbin drwx------ 10 vmail vmail 4.0K Sep 11 18:40 Maildir drwx------ 2 vmail vmail 4.0K Sep 11 19:46 cur -rw------- 1 vmail vmail 51 Sep 11 19:47 dovecot-uidlist -rw------- 1 vmail vmail 8 Sep 11 19:47 dovecot-uidvalidity -r--r--r-- 1 vmail vmail 0 Sep 11 19:46 dovecot-uidvalidity.5230c8a2 -rw------- 1 vmail vmail 248 Sep 11 19:47 dovecot.index.log -rw------- 1 vmail vmail 24 Sep 11 19:47 dovecot.mailbox.log -rw------- 1 vmail vmail 15 Sep 11 22:08 maildirsize drwx------ 2 vmail vmail 4.0K Sep 11 19:46 new drwx------ 3 vmail vmail 4.0K Sep 11 15:44 sieve -rw------- 1 vmail vmail 5 Sep 11 19:47 subscriptions drwx------ 2 vmail vmail 4.0K Sep 11 19:46 tmp Which I shouldn't see correct?

As above the maildir is correct. The only two places I can think are 90-plugin.conf which are my sieve settings. plugin { # The location of the user's active script: sieve = ~/.dovecot.sieve # If the user has no personal active script (i.e. if the file # indicated in sieve= does not exist), use this one: sieve_global_path = /var/lib/dovecot/sieve/default.sieve # The include extension fetches the :personal scripts from this # directory. When ManageSieve is used, this is also where scripts # are uploaded. sieve_dir = ~/sieve # The include extension fetches the :global scripts from this # directory. sieve_global_dir = /var/lib/dovecot/sieve/global/ } But I don't see how that would affect it. And the password and user queries were changed for the quotas. password_query = SELECT username AS user, password,CONCAT('/var/vmail/', maildir) AS userdb_home,\ '5000' AS userdb_uid, '5000' AS userdb_gid,\ concat('*:storage=', quota) AS userdb_quota_rule\ FROM mailbox WHERE username='%u' AND domain='%d' AND active=1 user_query = SELECT CONCAT('/var/vmail/', maildir) AS home, 'maildir:~/' as mail, '5000' AS uid, '5000' AS gid,\ concat('*:storage=', quota) AS quota_rule\ FROM mailbox WHERE username='%u' AND domain='%d' AND active=1 maildir in the mailbox is domain/user/ <- do I have to concat on Maildir in the query?

[Dovecot] Default mail folders.
by Bruce Markey 11 Sep '13

11 Sep '13

Just want to make sure before I set this up. I read that the autocreate plugin is deprecated and to use "Mailbox settings" as listed here http://wiki2.dovecot.org/MailboxSettings. If that is correct then do I just add those mailbox blocks in /etc/dovecot/conf.d/10-mail.conf? Lastly, will "sent items" auto populate with sent items or is there something else that needs to be done. I just switched over from courier and I'm still getting used to where/how things are done.

[Dovecot] Sieve, vacation, company (domain-wide) message possible?
by Charles Marcus 10 Sep '13

10 Sep '13

Hello, I've been using vacation.pl from postfixadmin for many years, and since the most recent modification that allows me to specify my own strings to test for for when NOT to send a message, I'm extremely happy with it (no more auto-responses to linked-in/facebook crap, etc)... But, there is one thing I'd like to be able to do that it can't do, and there hasn't been any positive response about implementing it, so I'm asking about if this is possible to do with sieve right now, and if not, how hard would it be to implement... What I'd like is to be able to set a company (domain-wide) auto-response for when our company is closed for holidays... more specifically, extra holidays (often the boss will close an extra day for an extra long weekend). He has asked more than once about setting an auto-response for *everyone* during these periods... Thanks, -- Best regards, */Charles/*

[Dovecot] Sieve Filter global vs user specific
by inkubus 10 Sep '13

10 Sep '13

Hi@all! I'm actually fighting to make sieve in dovecot work and made quite a success by now. However, I still fail at the following constellation: Background: I'm a Mail Admin of a small IT department and we are already using Dovecot as LDA with a filtering server. Any user can easily create filter rules that apply to him (to make it easier for my colleagues we use the Roundcube plugin for rule design). I can formulate global rules that apply to all. Individual users create their rules for redirectiong mails home (a la redirect: copy "users(a)theirhomes.de";) According to the policy of my company, certain file types (eg avi, mp4, mp3, wav, etc.) must NOT be sent out to the internet. But our phone system does INTERNALLY just that - receiving calls in absence of the user it sends mails with attachments MP3 (the spoken message). These mails must of course not be forwarded outside. I also created a global rule, which supresses the delivery of these mails (using the stop command), But after my global rule follows the user specific rule and the message ist sent anyway. QUESTION: Can cause dovecot somehow not to follow the user specific rules that apply to a message after going through my global ones? The mail has to remain directly in the inbox (and must not be forwarded by the user specific filter aftwerwards) My configuration: dovecot.conf (excerpt): plugin { sieve = /home/%n/.dovecot.sieve sieve_dir = /home/%n/.mailstore/sieve sieve_global_dir = /etc/dovecot/sieve/ sieve_before = /etc/dovecot/sieve/global } /etc/dovecot/sieve/global: require ["vacation","copy","fileinto","body","imap4flags"]; # rule:[Redirect] if anyof(header :contains "From" "f...ing.telefonanlage(a)firma.intern", header :contains "Subject" "Sprachnachricht") { stop; } user specific rules are as follows # rule:[Redirect] if true { redirect :copy "users(a)theirhomes.de"; } I hope my English is understandable (got quite a cold andfighting to keep my eyes open so my English is not the best today ;-) ) I'm sure the solution for this problem is a nobvious & simple one but I'm having my blond moments today... Any help would be appreciated! yours Sven P.S. Klar bin ich mir bewusst, dass einfach die Benutzerfilter aufgebohrt werden könnten. Da aber nicht alle Kollegen... sagen wir entsprechend firm... sind, würde ich den Pflegeaufwand gern gering halten und dieses Ausnehmen vo der weiterleitung zentralisieren. -- View this message in context: http://dovecot.2317879.n4.nabble.com/Sieve-Filter-global-vs-user-specific-t… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Proxy and Master Config
by Regan Yelcich 10 Sep '13

10 Sep '13

I'm just sitting down to configure a Proxy & Master Dovecot setup with Postfix and virtual users. I have read plenty about how to configure Dovecot as a proxy, but I'm unclear what's required on the "master" end. Does the master need the -pop and -imap scripts? or does the proxy handle that and call -deliver on the master? Can anyone explain the basic setup so I get it right. Thanks.

Re: [Dovecot] Is dovecot locking properly?

Probably too quick (or perhaps you haven't configured dotlocking). Qpopper locks the INBOX when it creates a drop copy: this can be a time consuming operation, during which you can see the .$user.pop lock file. Dovecot is more intelligent: it doesn't create copies, and goes out of its way to avoid grautitous I/O. Most of the operations can be done by consulting the indices. However, I did contrive a situation to observe lock files being created. 1) Create large INBOX file test user (assuming mbox /inbox/testuser) 2a) In one window, run a shell loop monitor while : ; do ls -al /inbox/testuser.lock done 2b) In another window, create a POP3 session and do an operation that would require a lock: telnet pop-server 110 USER testuser PASS testpassword DELE 1 ... this still won't need locking -- not until ... QUIT If you use maildir format, it may still be too quick to catch. in this situation, you can process trace the pop3 worker process to verify a lock file is created. > Is this .pop file a lock file or just a temporary file? Temporary. If you have them lying around, qpopper crashed. Note: dovecot makes lockfiles of the form "$user.lock". > If its a temp file does dovecot do the same thing elsewhere? I'm > concerned dovecot is not locking properly and there will be mailbox > corruption, so I'm trying to get dovecot to mimic what qpopper does as > much as possible. By "mimic" you mean that locking works, but otherwise, you don't want dovecot to mimic qpopper: the former is much better. I have not had problems with users complaining about scrambled files. As I said, process trace your pop3 worker process if you need to verify the locking process. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] sieve vacation question
by Andreas Schulze 09 Sep '13

09 Sep '13

Hello Stephan, I love to use the vacation extension to build an echo service. I have not to worry about whether to answer or not if the sender is a list, postmaster, mailer-daemon or other crasy thing. But i like to echo the *complete headers* back. I did not found a solution with sieve yet. Is it really impossible? Thanks Andreas
