Hi Timo, the attached patch seems to solve a warning from autoconf: libtoolize: Consider adding `AC_CONFIG_MACRO_DIR([m4])' to configure.in and libtoolize: rerunning libtoolize, to keep the correct libtool macros in-tree. Best regards, Luca

[Dovecot] Password auth scheme question with mysql
by Ed W 28 Jan '12

28 Jan '12

Hi, I have a current auth database using mysql with a "password" column in plain text. The config has "default_pass_scheme = PLAIN" specified In preparation for a more adaptable system I changed a password entry from "asdf" to "{PLAIN}asdf", but now auth fails. Works fine if I change it back to just "asdf". (I don't believe it's a caching problem) What might I be missing? I was under the impression that the password column can include a {scheme} prefix to indicate the password scheme (presumably this also means a password cannot start with a "{"?). Is this still true when using mysql and default_pass_scheme ? Thanks for any hints? Ed W

Dear friends, I try configure a webmail on my server using Postfix + Dovecot + MySQL + Squirrelmail. My system is a Debian6 and dovecot version is: #dovecot --version 1.2.15 But, when I try to access an account on squirrel I recieve this message: “ERROR Error connecting to IMAP server: localhost. 111 : Connection refused” Looking for a problem I foud this: #service dovecot start Starting IMAP/POP3 mail server: dovecotLast died with error (see error log for more information): Auth process died too early - shutting down If you have trouble with authentication failures, enable auth_debug setting.

[Dovecot] dovecot imap cluster
by Matteo Cazzador 28 Jan '12

28 Jan '12

Hello, i'm using postfix like smtp server, i need to choose an imap server with a special features. I have a customer with 3 different geographic locations. Every locations have a mail server for the same domain (example.com) If user1(a)example.com receive mail form external this mail going on every locations server. I've a problem now, is it possible to syncronize the state (mail flag) of user1 imap folder mails on every mail locations server? Example, if user1 read a mail on server one is it possible to change flag of the same mail file on server 2 and server 3? Is it possible to use dsync for it? I need something like imap cluster. Or an action in post processing imap mail read. I can't use distribuited file system. Thank's a lot -- Rispetta l'ambiente: se non ti è necessario, non stampare questa mail. ****************************************** Ing.

[Dovecot] v2.1.rc5 released
by Timo Sirainen 27 Jan '12

27 Jan '12

http://dovecot.org/releases/2.1/rc/dovecot-2.1.rc5.tar.gz http://dovecot.org/releases/2.1/rc/dovecot-2.1.rc5.tar.gz.sig I'm still lagging behind reading emails. v2.1.0 will be released after I've finished that. RC5 is already stable and used in production, but I want to make sure that I haven't missed anything important that was reported previously. Most of the recent fixed bugs existed also in v2.0 series. Changes since rc3: * Temporary authentication failures sent to IMAP/POP3 clients now includes the server's hostname and timestamp. This makes it easier to find the error message from logs. + auth: Implemented support for Postfix's "TCP map" sockets for user existence lookups. + auth: Idling auth worker processes are now stopped. This reduces error messages about MySQL disconnections. - director: With >2 directors ring syncing might have stalled during director connect/disconnect, causing logins to fail. - LMTP client/proxy: Fixed potential hanging when sending (big) mails - Compressed mails with external attachments (dbox + SIS + zlib) failed sometimes with bogus "cached message size wrong" errors. (I skipped rc4 release, because I accidentally tagged it too early in hg.)

Re: [Dovecot] auth-worker temporary failures causing lmtp 500 rejection
by Mark Zealey 26 Jan '12

26 Jan '12

Hi Timo thanks for the patch; I have now analyzed network dumps & discovered that the cause is actually our frontend mail servers not dovecot - we were delivering to the wrong lmtp port which we then use in the mysql query hence getting empty records. Sorry about this! Mark ________________________________________ From: Mark Zealey Sent: 26 January 2012 14:37 To: Timo Sirainen Cc: dovecot(a)dovecot.org Subject: RE: [Dovecot] auth-worker temporary failures causing lmtp 500 rejection I've tried reproducing by having long running auth queries in the sql and KILLing them on the server, restarting the mysql service, and setting max auth workers to 1 and running 2 sessions at the same time (with long-running auth queries), but to no effect. There must be something else going on here; I saw it in particular when exim on our frontend servers had queued a large number of messages and suddenly released them all at once hence the auth-worker hypothesis although the log messages do not support this. I'll try to see if I can trigger this manually although we have been doing some massively parallel testing previously and not seen this.

Is this an issue with the code or perhaps some setting I have missed? The problem is that temporary errors are returning "unknown user". Can you reproduce this somehow? Like if you stop MySQL it always returns that "Unknown user"?

[Dovecot] auth-worker temporary failures causing lmtp 500 rejection
by Mark Zealey 26 Jan '12

26 Jan '12

Hi there, I'm using dovecot 2.0.16 with a mysql user database. From time to time when we have a big influx of messages (perhaps more than 30 concurrent rcpt to:<> sessions at the same time so no auth-workers free?) or when we have a transient issue connecting to the database server, we see the message: Jan 25 16:38:23 mailbox dovecot: auth-worker: sql(foo(a)bar.com,1.2.3.4): Unknown user and the lmtp process returns: 550 5.1.1 <foo(a)bar.com> User doesn't exist: foo(a)bar.com This would be correct for a permanent error where the user doesn't exist in our database, however it seems to be doing this on transient errors too. Is this an issue with the code or perhaps some setting I have missed? Thanks, Mark

[Dovecot] Persistence of UIDs
by Jean-Daniel Beaubien 26 Jan '12

26 Jan '12

Hi everyone, I have a question concerning UIDs. How persistant are they? I am thinking about building some form of webmail specialized for some specific business purpose and I am thinking of building a sort of cache in a DB by storing the email addr, date, subject and UID for quick lookups and search of correspondance. I am doing this because I am having issue with multiple people searching thru email folders that have 100k+ emails (which is another problem in itself, searches don't seem to scale well when folder goes above 60k emails). So to come back to my question, can I store the UIDs and reuse those UIDs later on to obtain the body of the email??? Or can the UIDs change on the server and they will not be valid anymore?. My setup is: - dovecot 1.x (will migrate to 2.x soon) - maildir - everything stored on an intel 320 SSD (index and maildir folder) Thanks, -JD

Dear Sir, Thanks for your reply and I really agreed your point about 'reject mail for users over quota', but I don't want to do it if it is possible to without reject mails to deliver mails from spool to user's home directory automatically, kindly provide solution.

I'll be in FOSDEM giving a small lightning talk about Dovecot: http://fosdem.org/2012/schedule/event/dovecot I'll also be around in FOSDEM the whole time, so if you're there and want to talk to me about anything, send me an email at some point. Poll to dovecot-news list people: Do you want to see these kind of news about my upcoming talks sent to the list? Probably happens a few times/year. A simple "yes" or "no" reply to this mail privately to me is enough.

[Dovecot] Dovecot antispam plugint got an empty message
by Petr Bravenec 25 Jan '12

25 Jan '12

Few weeks ago I upgraded dovecot from 1.2 to 2.0.16 and antispam plugin to 2.0_pre20101222. Since the upgrade I'm not able to move messages to my Junk folder. In the maillog I have found this message: dspam[25060]: empty message (no data received) Message is copied from my INBOX to Junk folder, but dspam got an empty message and sent an error return code. So the moving operation is not successfull and the original message in INBOX was not deleted. The dspam was not trained (got an empty message). Looking to source code of dspam and antispam plugin I suspect the dovecot not to sending any content to plugin. Can you help me, please? Petr Bravenec

Hi, I am using dovecot 2.0.16, and assigend globally procmailrc (/etc/procmailrc) which delivers mails to user's home directory in maildir formate. Also I assined quota to User through setquota (edquota) command, If the quota excedded then this case user's mail store to /var/spool/mail/user. After incresing quota how to delivered these mails to user's home dir in maildir formate automatically.

[Dovecot] Imap Quota Exceeded - But Still Receiving Emails?
by Palatine Web Support 25 Jan '12

25 Jan '12

Hello I am trying to setup dovecot maildir quota, but even though it seems to be working fine, I am still receiving emails into my inbox even though I have exceeded my quota. Here is my dovecot config: plugin { quota = maildir:User Quota quota_rule2 = Trash:storage=+100M } And my SQL config file for Dovecot (dovecot-sql.conf): user_query = SELECT '/var/vmail/%d/%n' as home, 'maildir:/var/vmail/%d/%n' as mail, 150 AS uid, 8 AS gid, CONCAT('*:storage=', quota) AS quota_rule FROM mailbox WHERE username = '%u' AND active = '1' CONCAT('*:storage=', quota) AS quota_rule quota_rule = *:storage=3M So it picks up my set quota of 3MB but dovecot is not rejecting emails if I am over my quota. Can anyone help? Thanks. Carl

They will *always* use port 25 and nothing else. If your problem is that your Internet Service Provider is blocking port 25, you can contact them. Some ISPs will unblock port 25 on request, or might even have an online form you can fill out. If you can't get help from the ISP, you need a remailer service -- some outside proxy that accepts the mail for you and forwards connections to some different port on your computer.

This is made obvious by your questions, and failure to understand that port 25 is *the* port for receiving email on the public internet. Period. If your main problem with port 25 is *sending* (relaying outbound) mails, then you will need to take this up with your ISP. If they are unable or unwilling to address the problem, one option would be to setup your system to relay through some other smtp relay service on the internet using port 587 as you apparently read somwehere, but you don't do this by changing the main smtpd daemon to port 587, because as you discovered, you won't be able to receive *any* emails like this.

[Dovecot] Trying to get metadata plugin working
by Thomas Koch 24 Jan '12

Hi, I'm working on a Kolab related project and wanted to use dovecot on my dev machine. However I'm stuck with the metadata-plugin. I "solved" the permissions problems but now I get dict: Error: file dict commit: file_dotlock_open(~/Maildir/shared-metadata) failed: No such file or directory Before that, I had dict { metadata = file:/var/lib/dovecot/shared-metadata but got problems since my normal user had no permission to access /var/lib/dovecot. I compiled the plugin from the most recent commit. My dovecot runs in a chroot. I can login with KMail and can create Groupware (annotated) folders, but the metadata file dict won't get created and I also can't set/get metadata via telnet. doveconf -N # 2.0.15: /etc/dovecot/dovecot.conf # OS: Linux 3.1.0-1-amd64 x86_64 Debian 6.0.3 auth_mechanisms = plain dict { metadata = file:~/Maildir/shared-metadata } mail_access_groups = dovecot mail_location = maildir:~/Maildir mail_plugins = " metadata" passdb { driver = pam } plugin { metadata_dict = proxy::metadata } protocols = " imap" service dict { unix_listener dict { group = dovecot mode = 0666 } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } protocol imap { mail_plugins = " metadata imap_metadata imap_annotatemore" } Best regards, Thomas Koch, http://www.koch.ro

[Dovecot] Capabilities of imapc
by René Neumann 24 Jan '12

24 Jan '12

Hi *, I can't find any decent information about the capabilities of imapc in the planned future dovecot releases. As I think about using imapc, I'll just give the two use-cases I see for me. Will this be possible with imapc? 1) One (or more) folders in a mailbox which are proxied? 2) Proxy a whole mailbox _and use the folders in it as shared folders_. That means account X on Server 1 (the dovecot box) is proxied via imapc to Server 2 (some other server). The folders of this account on Server 1 are then shared with account Y. When account Y uses these folders they are always up-to-date (so no action of account X is required). The second use-case is just some (ugly) workaround in case the first one is not possible. Thanks, René

[Dovecot] Director questions
by Mark Moseley 23 Jan '12

23 Jan '12

In playing with dovecot director, a couple of things came up, one related to the other: 1) Is there an effective maximum of directors that shouldn't be exceeded? That is, even if technically possible, that I shouldn't go over? Since we're 100% NFS, we've scaled servers horizontally quite a bit. At this point, we've got servers operating as MTAs, servers doing IMAP/POP directly, and servers separately doing IMAP/POP as webmail backends. Works just dandy for our existing setup. But to director-ize all of them, I'm looking at a director ring of maybe 75-85 servers, which is a bit unnerving, since I don't know if the ring will be able to keep up. Is there a scale where it'll bog down? 2) If it is too big, is there any way, that I might be missing, to use remote directors? It looks as if directors have to live locally on the same box as the proxy. For my MTAs, where they're not customer-facing, I'm much less worried about the latency it'd introduce. Likewise with my webmail servers, the extra latency would probably be trivial compared to the rest of the request--but then again, might not. But for direct IMAP, the latency likely be more noticeable. So ideally I'd be able to make my IMAP servers (well, the frontside of the proxy, that is) be the director pool, while leaving my MTAs to talk to the director remotely, and possibly my webmail servers remote too. Is that a remote possibility?

[Dovecot] LMTP ignoring tcpwrappers
by Harm Weites 23 Jan '12

23 Jan '12

Hello, we want to use dovecot LMTP for efficient mail delivery from our MX servers (running postfix 2.8) to our storage servers (dovecot 2.0.17). However, the one problem we see is the lack of access control when using LMTP. It apears that every client in our network who has access to the storage machines can drop a message in a Maildir of any user on that storage server. To prevent this behaviour it would be nice to use libwrap, just as it can be used for POP3/IMAP protocols. This, however, seems to be impossible using the configuration as mentioned on the dovecot wiki: login_access_sockets = tcpwrap service tcpwrap { unix_listener login/tcpwrap { group = $default_login_user mode = 0600 user = $default_login_user } } This seems to imply it only works for a login, and LMTP does not use that. The above works perfectly when trying to block access to IMAP or POP3 in /etc/hosts.deny, though a setting for LMTP is simply ignored. Is there a configuration setting needed for this to work for LMTP, or is it simply not possible (yet) and does libwrap support for LMTP requires a patch? Any help is appreciated. Regards, Harm

IMAP proxy could be a problem if the user had opened more than 10 (unique) mailboxes. The proxy would keep this connection open until a timeout, and after some time, could accumulate more connections than your limit. The lack of proxy could solve your problem if for some reason your webmail software is not closing the IMAP connection properly (I assume IMP does a connect/authenticate/IMAP command/logout for every webmail operation). Every connection (even to the same mailbox) would open up a new connection. The proxy software will recognize the reconnnection and funnel it through its cached connection. You can lsof the user's IMAP processes (or troll through /proc/{imap-process} or what you have) to figure out which mailboxes it has opened. On my system, file descriptor 9 and 11 gives you the names of the index files that indicate which mailboxes are being accessed. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Clients show .subscriptions folder
by Mark Sapiro 21 Jan '12

21 Jan '12

Since upgrading from dovecot-2.1.rc1 to dovecot-2.1.rc3, some clients are showing a .subscriptions file in the user's mbox path as a folder. Some clients such as T'bird on Mac OS X create this file listing subscribed mbox files. Other clients such as T'bird on Windows XP show this file as a folder in the folder list even though it cannot be accessed as a folder (dovecot returns CANNOT Mailbox is not a valid mbox file). I think this may be a result of uncommenting the inbox namespace in conf.d/10-mail.conf <http://hg.dovecot.org/dovecot-2.1/rev/2c8d39467f21>. Is there a way to supress exposing this file to clients that don't use it? # dovecot -n # 2.1.rc3: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.18-8.1.14.el5 i686 CentOS release 5 (Final) auth_mechanisms = plain apop login auth_worker_max_count = 5 mail_location = mbox:~/Mail:INBOX=/var/spool/mail/%u mail_privileged_group = mail mbox_write_locks = fcntl dotlock namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = /usr/local/etc/dovecot.passwd driver = passwd-file } passdb { driver = pam } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } } ssl_cert = </etc/httpd/conf/ssl/combined.crt ssl_key = </etc/httpd/conf/ssl/www.grizz.org.key userdb { driver = passwd } protocol imap { mail_max_userip_connections = 30 } # -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

[Dovecot] Performance of Maildir vs sdbox/mdbox
by Lee Standen 20 Jan '12

20 Jan '12

Hi Guys, I've been desperately trying to find some comparative performance information about the different mailbox formats supported by Dovecot in order to make an assessment on which format is right for our environment. This is a brand new build, with customer mailboxes to be migrated in over the course of 3-4 months. Some details on our new environment: * Approximately 1.6M+ mailboxes once all legacy systems are combined * NetApp FAS6280 storage w/ 120TB usable for mail storage, 1TB of FlashCache in each controller * All mail storage presented via NFS over 10Gbps Ethernet (Jumbo Frames) * Postfix will feed new email to Dovecot via LMTP * Dovecot servers have been split based on their role - Dovecot LDA Servers (running LMTP protocol) - Dovecot POP/IMAP servers (running POP/IMAP protocols) - LDA & POP/IMAP servers are segmented into geographically split groups (so no server sees every single mailbox) - Nginx proxy used to terminate customer connections, connections are redirected to the appropriate geographic servers * Apache Lucene indexes will be used to accelerate IMAP search for users Our closest current live configuration (Qmail SMTP, Courier IMAP, Maildir) has 600K mailboxes and pushes ~ 35,000 NFS operations per second at peak Some of the things I would like to know: * Are we likely to see a reduction in IOPS/User by using Maildir alone under Dovecot? * What kind of IOPS/User reduction could we expect to see under mdbox? * If someone can give some technical reasoning behind why mdbox does less IOPS than Maildir? I understand some of the reasons for the mdbox IOPS question, but I need some more information so we can discuss internally and make a decision as to whether we're comfortable going with mdbox from day one. We're very familiar with Maidlir, and there's just some uneasiness internally around going to a new mail storage format. Thanks!

[Dovecot] mail_max_userip_connections exceeded.
by Simon Brereton 20 Jan '12

20 Jan '12

Hi I'm using Dovecot version 1:1.2.15-7 installed on Debian Squeeze via apt-get.. I have this error in the logs. /var/log/mail.log.1:2490:Jan 19 12:02:55 mail dovecot: imap-login: Maximum number of connections from user+IP exceeded (mail_max_userip_connections): user=<user(a)example.com>, method=PLAIN, rip=127.0.0.1, secured I never changed this from the default 10. When I googled this error there was a thread on this list from May 2011 that indicated one would need one connection per user per subscribed folder. However, I know that user doesn't have 10 folders, let alone 10 subscribed folders! I can increase, it but it's not going to scale well. And there are people on this list with many 1000x users than I have - so how do they deal with that? 127.0.0.1 is obviously webmail (IMP5). So, how/why am I seeing this, and should I be concerned?

[Dovecot] shared folder files not displaying in thunderbird
by Eric Broch 19 Jan '12

19 Jan '12

Hello, I have dovecot installed with the configuration below. One of the subfolders created (using the email client) under the '/home/vpopmail/domains/mydomain.com/shared/projects' share no longer (it used to) displays the files located in it. There are about 150 folders under the '/home/vpopmail/domains/mydomain.com/shared/projects' share all of which display the files located in them, the one mentioned used to display the contents but no longer does. What would be the reason that one folder would no longer display existing files in the email client (Thunderbird) and the other folders would? And, how do I fix this? I've already tried unsubscribing and resubscribing the folder. This did not work. Would it now be simply a matter of unsubscribing the folder, deleting the dovecot files, and resubscribing to the folder?

In 2.0.17 you increased LOGIN_MAX_INBUF_SIZE from 1024 to 4096. Should you also have increased MASTER_AUTH_MAX_DATA_SIZE from (1024*2) to (4096*2)? /* This should be kept in sync with LOGIN_MAX_INBUF_SIZE. Multiply it by two to make sure there's space to transfer the command tag */

Just had a minor suggestion, with no clue how hard/easy it would be to implement: The %f flag in deliver_log_format seems to pick up the From: header, instead of the "MAIL FROM:<...>" arg. It'd be handy to have a %F that shows the "MAIL FROM" arg instead. I'm looking at tracking emails through logs from Exim to Dovecot easily. I know Message-ID can be used for correlation but it adds some complexity to searching, i.e. I can't just grep for the sender (as logged by Exim), unless I assume "MAIL FROM" always == From:
