Quota SQL separate queries?
by Akos Vandra 22 Jun '15

22 Jun '15

Hello, We are trying to enforce per-domain quotas. Currently my quota-sql.conf looks like this: connect = host=/var/run/postgresql dbname=mail user=mailreader map { pattern = priv/quota/storage table = quota username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota username_field = username value_field = messages } With quota = dict:Domain:%d:proxy::sqlquota This works with a trigger by updating and , however I am unable to show the administrators a list of which of their users are using the most space. That is to be purely informative, and is not to be enforced. I would appreciate if there was a documented way to specify exact SQL queries to run for inserting, updating and selecting from the quota storage, something like this: -- CREATE VIEW quota_domain AS SELECT domain, sum(bytes), sum(messages) FROM quotas GROUP BY domain INSERT/UPDATE INTO quotas(username, domain, bytes, messages) SELECT bytes, messages from quota_domain WHERE domain = %d Is there such a possibility? If not, can you suggest a workaround to have a list of per-user quota usages as well as enforced per-domain quotas? Thanks, Akos Vandra

Mailbox aliases problem
by azurIt 22 Jun '15

22 Jun '15

Hi, i'm trying to implement malbox aliases but it's not fully working as i expected. This is my configuration: mail_plugins = acl mailbox_alias plugin { mailbox_alias_old = INBOX/Odoslane mailbox_alias_new = INBOX/SentTest } That 'INBOX/' must be there because of this (we were moving from Courier IMAP): namespace inbox { type = private prefix = INBOX/ separator = / inbox = yes list = yes } All of this is working fine, if i create folder SentTest, the link to folder Odoslane is correctly created on filesystem. The problem is that folder SentTest is invisible even after creation: 1 CREATE "INBOX/SentTest" 1 OK Create completed. 2 LIST "" "*" <all folders except SentTest are listed> 2 OK List completed. 3 LIST "INBOX/SentTest" "*" 3 OK List completed. 4 LIST "INBOX/Odoslane" "*" 4 LIST (\HasNoChildren \Sent) "/" INBOX/Odoslane 4 OK List completed. 5 CREATE "INBOX/SentTest" 5 NO [ALREADYEXISTS] Mailbox already exists 6 DELETE "INBOX/SentTest" 6 OK Delete completed. None of the e-mail clients i tried can see the folder. I'm using Dovecot 2.2.13 from Debian Wheezy (wheezy-backports). Any hints? azur

setting quota through IMAP
by Daniel Tröder 22 Jun '15

22 Jun '15

I'd like to set the quota of a user through the IMAP protocol. I use Pythons imaplib: imap.setquota("test1m(a)uni.dtr", "(storage 8192)") ('NO', ['Quota can be changed only by admin.']) So... which user is the "admin" user in a virtual user setting (passwd: PAM, userdb: LDAP)? Greetings Daniel

how do I conceptualize system & virtual users?
by lejeczek 22 Jun '15

22 Jun '15

I guess this would be a common case, I am hoping for some final clarification. a few Linux boxes share ldap (multi-master) backend that PAM/SSSD uses to authenticated users, and these LDAPs are also is used by Samba, users start @ uid 1000. Boxes are in the same both DNS and Samba domains. Do I treat these users as system or virtual users from postfix/dovecot perspective? If it can be a matter of choice then which is better/best? many thanks.

The first bonehead maneuver seems to be: location = virtual:/var/mail/%%d/%%n/mdbox/virtual I'm thinking it should be: location = virtual:/var/mail/%%d/%%n/mdbox/mailboxes/virtual But...it didn't seem to make a difference.

Dovecot 2.2.16: disappearing messages, mismatched summaries, duplicated messages, excessive full re-downloads
by David Gessel 20 Jun '15

20 Jun '15

My Dovecot 2.2.16 server is interacting poorly with a variety of mail clients. The symptoms include disappearing messages, mismatched summaries, duplicated messages, and excessive full re-downloads. Dovecot 2.2.16 on FreeBSD 10.1-release r280247M ZFS is interacting suboptimally with various email clients. Output of "dovecot -n" further down. *Client Artifacts* Thunderbird 31.6 Win 7 Ultimate SP1: - messages disappear and reappear with checks somewhat randomly. - Sometimes full re-download of folders is triggered, also seems random - Copies of messages appear, sometimes multiplying with each mail check up to about 5-8 or so of each message. - The summary information in the list pane doesn't match the message headers in the preview pane - quit and restart always cleans it up. - sometimes changing folders cleans it up, but not always - sometimes instigating a manual mail check cleans it up but not always Mulberry 4.08 Win 7 Ultimate SP1: - messages disappear and reappear - full re-scans of entire folders triggered occasionally when changing folders, but not always - message list filled with semi-blank entries (message number, status flags, and dates are listed, but no sender, subject, or body is available). The time stamps do not appear to be correct "date received". - message list fills with duplicates - the last of the set of duplicates, which are not necessarily sequentially numbered, has load-able body text and headers, but the others do not. There may be 3-5 copies, only one of which is the real message. The inbox is sequentially numbered by "message number" (the "natural order of the mailbox") and duplicates have unique numbers. - If there's a deleted message left, the "expunge" button is enabled and this also restores normal mailbox view. - disconnecting and reconnecting usually fixes the issues - changing mailboxes while connected sometimes fixes the issues. Claws 3.10.1 Win 7 Ultimate SP1 - initial load is correct, but once claws tries to sync mail, it locks up and never releases (even after days). Claws is weird like that. Sylpheed 3.4.2 Win 7 Ultimate SP1 - mail list always looks fine, but sometimes clicking a message shows "can't display" in the preview pane - "get messages" restores access to messages. Thunderbird 31.5 Linux Mint 17 Qaina 3.13.0-24-generic - messages disappear and reappear with checks somewhat randomly. - Sometimes full redownload of folders is triggered, also seems random - Copies of messages appear, sometimes multiplying with each mail check - The summary information in the list pane doesn't match the message headers in the preview pane - wrong message total (every other client agrees on 2576 but TB-linux says 3242, perhaps counting dups) Claws 3.9.3 Linux Mint 17 Qaina 3.13.0-24-generic - Occasionally shows "this message can't be displayed" - executing a "get mail" fixes the error K-9 5.004 Android 4.3 - messages appear and then disappear on the next check - message body is occasionally blank (only subject and arrival time appear, no body preview line, clicking on the message shows "no text" *Server artifacts:* dovecot.log shows runs of this error: Apr 15 09:02:37 imap(user(a)domain.com): Warning: Maildir /mail/domain.com/user//.Sent: Expunged message reappeared, giving a new UID (old uid=306286, file=1429102024.M826331P1156.host,S=1678,W=1724:2,S) or this error: Apr 15 10:04:00 indexer-worker(user(a)domain.com): Warning: Maildir /mail/domain.com/user//.Sent: Expunged message reappeared, giving a new UID (old uid=306803, file=1428785463.M645546P27215.host,S=5389,W=5442:2,S) # grep -c "Expunged message reappeared" dovecot.log.0 8981 The first entry in dovecot.log.0 is at Apr 15 10:00:12, and the last entry at Apr 15 12:00:13; Dovecot is logging 4,490 expunged message reappeared messages per hour.

I tried removing most of my customizations one by one and testing, but the problem has not been improved. I strongly suspect that the index files are getting thrashed or otherwise abused. I have no idea what's triggering whatever event is resulting in the thousands of expunged messages reappearing, but the client artifacts suggest a mismatch between cache or index files and files on disk: UID, keywords, and set date appear as if from cache but the body of the message does not. It seems as if the UID doesn't match a message on disk any more, which soon gets automatically fixed and everything syncs again until something re-triggers - a false expunge perhaps? Or perhaps the transaction log is suffering some sort of ongoing abuse? *dovecot -n* # dovecot -n # 2.2.16: /usr/local/etc/dovecot/dovecot.conf # Pigeonhole version 0.4.7 # OS: FreeBSD 10.1-RELEASE

I think reason was a damaged Index in ~username/mail/.imap/INBOX/ I removed this folder and immediately errors are gone and Mailbox was readable again. Never noticed this kind of errors for years on 2.1.17, maybe this helps to find a Bug in Code. Thanks, Hajo

hi everybody I've barely started reading on dsync and I wonder.. would you know if it is possible to sync/replicate only specific domain(users)? or it's always the whole lot? many thanks P.

Dovecot 2.1.9 shared folder deletion causes fault
by JT 19 Jun '15

19 Jun '15

Hey all, I'm getting a fault in dovecot (see below) using shared folders. I have a mailbox that receives new mail (Account X/INBOX). Another account (Account A) has access to the other account (Account X/INBOX) with ACL below. The ACL directory (.DEFAULT) contains: user=AccountA lrwst I removed a test email from Account A/INBOX, which is supposed to remove the email from Account X/INBOX. A fault occurs whenever my client (Thunderbird) attempts to connect and complete the deletion. Other actions complete successfully. It only appears to happen when using Thunderbird. Mac Mail does not cause the fault. I'm not getting a core dump so all I have is what the log outputs. I can reproduce this regularly so let me know if you need any additional information.

maildir, how to always add size tags to filename (,S=).
by Sergei Franco 19 Jun '15

19 Jun '15

Hi There, I have thoroughly read through documentation and wiki and I simply cannot find how to force dovecot to always add the size tag to the filename when using maildir format. We are using dovecot 2.2.9 (whatever comes from ubuntu 14.04 LTS). We are using dovecot in conjunction with exim with maidirsize file enabled and maildir quotas. For example exim has following configuration: maildir_tag = ,S=$message_size Which adds the size to the filename of the message. This has enormous (orders of magnitude) performance benefit as to calculate quota one does not need to stat every single file (only getents for each directory). I have wrote a script that adds the size tag retrospectively to files it didn't had it, and rebuild the dovecot index/cache if changes where made. This worked fine. Behaviour of dovecot is very peculiar: it generally adds the ,S= tag (along with ,W= tag) but occasionally it does not (I wander if it depends on the IMAP client). Is there anyway to force dovecot to add size tag to the files (like with exim example above)? Thank you very much. Sergei.

Best practices for mailbox network file storage?
by Andy Csillag 18 Jun '15

18 Jun '15

Is there a current best practice for a shared filesystem backend for mailboxes (in my case, all virtual accounts)? NFS 3/4, GFS2, GlusterFS, other? In the case of the latter ones, is the use of Director necessary? Any specific anti-recommendations? Also, if it matters, I *think* I want to use BackBlaze racks for storage. Also, I've seen recommendations for the filesystem underneath like XFS or ext4 or whatever. Is there a best practice? Thanks, Drew

LMTP with Postfix Problem
by Steve Matzura 18 Jun '15

18 Jun '15

Here's a maillog entry that's one of many I receive when I try sending a test message to my system. The recipient is a virtual user in /etc/virtual. The way I'm expecting it to work is that my message from me to this Postfix virtual user will be sent back to me. Every time the message delivery is attempted, Dovecot says the LMTP directory doesn't exist. I thought it was created automatically as messages arrive. Jun 18 01:48:27 <machine-name> postfix/lmtp[30644]: 4CA5B8CB6: to=<postmaster@<my-domain>>, orig_to=<postmaster>, relay=none, delay=0.02, delays=0.02/0/0/0, dsn=4.4.1, status=deferred (connect to <my-FQDN>[private/dovecot-lmtp]: No such file or directory)

Pigeonhole vacation from alias address
by Dino Blazeka 18 Jun '15

18 Jun '15

Hi everyone. I've set up my instance not to check recipient address with sieve_vacation_dont_check_recipient=yes to enable users to set up their vacation script without listing addresses (there are to many). Only problem remaining is that when they receive an e-mail sent to their alias, the vacation response comes from their original mail address. Is there a setting or workaround that would enable vacation extension to send response with from field set to whichever address the original message was addressed to. Thank you in advance, Dino P. S. This is my first message to the list so I apologize in advance if I have broken any rules. It was not done intentionally

privilege of process executed by extprograms plugin
by Takahiro Yakoh 18 Jun '15

18 Jun '15

Hi, I'm just a beginner of extprograms plugin of sieve. When I execute a process via execute or pipe command, the process start with "root" privilege. Why? I believe the process must be executed with recipient privilege. Give me some checkpoints, or hints, please. My setup is as follows: Ubuntu 14.04.2 LTS 64bit + dovecot-core, dovecot-sieve plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_execute_bin_dir = /some/where sieve_extensions = +vnd.dovecot.execute +vnd.dovecot.pipe sieve_pipe_bin_dir = /some/where sieve_plugins = sieve_extprograms } protocol lmtp { mail_plugins = " sieve" postmaster_address = postmaster(a)some.where } Yakoh

bug in indexer/indexer-worker
by Infoomatic 18 Jun '15

18 Jun '15

Hi, I have already mentioned this in http://www.dovecot.org/pipermail/dovecot/2014-November/098592.html I could reproduce the errors above in a self-compiled v2.2.18 and the prebuilt packages from xi.rename-it.nl (in addition to version 2.2.15 mentioned in the link) The problem occurs when enabling fts_tika in the plugins (tried tika 1.6, 1.7 and 1.8). I tried to move a folder of my mailbox with about 2000 mails to my server (no users, modern hardware). At some point I get an error and from this time on dovecot keeps repeating the last lines with every mail that comes in ... see [1] I then get kernel syslog messages like in [2]. when I try to index all users (had another testuser) mailboxes with "doveadm index" I get the errors of [3]. The mailfolder does contain mails with attachments of all sorts, videos, office documents etc. When disabling fts_tika it works. dovecot -n output is [4] Could someone of the devs please have a look? best regards, infoomatic [1] Then comes the panic which produces loads of errormessages below the "Raw backtrace" part: Jun 16 10:11:08 testhost dovecot: indexer-worker(user1): Warning: I/O leak:

FTS lucene and english + german mails
by Felix Zielcke 17 Jun '15

Hi, I'm currently looking over the FTS pages to enable it in my dovecot. But I'm unsure what the best settings of the lucene plugin are, if you receive german and english mails. Wiki says: textcat_conf=<path> textcat_dir=<path>: If specified, enable guessing the stemming language for emails and search keywords. This is a little bit problematic in practice, since indexing and searching languages may differ and may not find even exact words because they stem differently. On Debian libstemmer is included in the debian-lucene package. So what settings are the best to have not the problem that exact words can't be found?
