[Dovecot] Received date no longer email date?
by Brian L. Matthews 29 Dec '11

29 Dec '11

I just upgrade from dovecot 1.2 to dovecot 2.0.16. I use dovecot as a local IMAP server to archive email from my corporate email account (on Exchange). I don't have any automated archiving, I just periodically move messages from my Exchange inbox to the IMAP inbox. I'm on Mac OS X 10.6.8 using Entourage as my mail client. In the previous version of dovecot, the Received date of the email was preserved when I moved a message, but it's not in 2.0.16, it's set to the date and time I move the message. If I open a message, the date displayed is the date on the message as expected. I converted my config from 1.2 with $ doveconf -n -c dovecot.conf > dovecot-2.conf It spit out various warnings but, once I'd created a dovenull user, seemed to work fine. Here's my configuration info: $ dovecot --version 2.0.16 $ dovecot -n # 2.0.16: /usr/local/etc/dovecot/dovecot.conf # OS: Darwin 10.8.0 i386 disable_plaintext_auth = no listen = 127.0.0.1 log_path = /var/log/dovecot.log mail_location = maildir:~/Maildir passdb { args = login driver = pam } service auth { user = root } service imap-login { process_limit = 16 } service imap { process_limit = 64 } ssl = no userdb { driver = passwd } I'd like to get it back to preserving the Received date, any help you can provide will be appreciated.

[Dovecot] proxying, SSL, and client certificate
by Mike Abbott 29 Dec '11

29 Dec '11

How do I configure dovecot-2.0.x to present a client SSL certificate when proxying? If dovecot on server1.example.com has: passdb { driver = static args = proxy=y host=server2.example.com nopassword=y ssl=yes } and dovecot on server2.example.com has: ssl_verify_client_cert = yes auth_ssl_require_client_cert = yes then when a client connects to server1 and authenticates, a connection is established to server2 but the SSL handshake fails because server1 doesn't present a client certificate. I don't see where ssl_client_ctx is tied to a client certificate in ssl-proxy-openssl.c. Thanks.

[Dovecot] Dovecot imap proxy to nginx, incompatible
by David Jonas 29 Dec '11

29 Dec '11

It appears that using dovecot to proxy to nginx imap proxy doesn't work. >From tcpdump and browsing the source it appears dovecot sends, C CAPABILITY\r\nL LOGIN <user> <pass>\r\n and nginx only responds to the CAPABILITY command. Is this a problem with dovecot sending the two commands without waiting for the first to complete or is it nginx's trouble with not handling it correctly? A quick test with a perl script confirms: #!/usr/bin/perl -w $|++; use IO::Socket; use strict; my ($host, $user, $pass) = @ARGV; my $s = new IO::Socket::INET(Proto => 'tcp', PeerAddr => $host, PeerPort => 143); die "Could not create socket $!\n" unless $s; while(<$s>) { print $_; last if /OK/; } print $s "C CAPABILITY\r\nL LOGIN $user $pass\r\n"; while(<$s>) { print $_; last if /OK/; } print $s "Q logout\r\n"; while(<$s>) { print $_; last if /OK/; } close($s); ## Output: * CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS UIDPLUS LIST-EXTENDED I18NLEVEL=1 QUOTA AUTH=PLAIN C OK completed * BYE Q OK completed

Dear all, I have been trying to get this problem out of the way but I just cant seem to get it right. I hope someone can point me in the right direction here. I have come up with a vacation script as below, which can be send out from my Postfix SMTP server to my smarthost at the ISP, and yet for some reason it is not sent out at my ISP server.

[Dovecot] Corrupted index cache file and high CPU usage
by hydra 24 Dec '11

24 Dec '11

I suspect, that dovecot v2.0.16 under Linux (tested on Gentoo 3.0.4 Hardened, Gentoo 3.0.6, Gentoo 3.1.4) causes 100% cpu utilization when index.cache is broken and doveadm is lanched. Dovecot uses LDAP as the userdb and provides IMAP and LDA. Because each user has a quota, the doveadm's expunge functionality is used to get rid of old trashed mail. The mail log: Dec 12 07:38:59 www dovecot: imap(user): Error: Corrupted index cache file /var/data/mail/domain.tld/user/mail/dovecot.index.cache: invalid record size Doveadm is launched as: doveadm -D expunge -A mailbox Trash savedbefore 1w Mail is stored on ext4 and flush will use all of the CPU capacity like this: load average: 4.00, 4.01, 4.05 ps: root 26401 98.2 0.0 0 0 ?

When this happens, I cannot unmount the drive nor a system reboot works. Thank you !

[Dovecot] Limit maximum connections for user/IP on proxy
by Martin Abrahamsson 23 Dec '11

23 Dec '11

Hi, Is it possible to limit the maximum number of IMAP connections allowed for a user from each IP address, on the proxy server instead of on the mail store server? mail_max_userip_connections works well when the client is connection to the mail store without proxy, but when using proxies the POP/IMAP server will register the remote IP (rip) as the proxy server's IP address - thus a low limit will be reached quite easily. Thanks -- Martin Abrahamsson

[Dovecot] Patch for dovecot 1.2.16 (and .17) for vpopmail module
by Alessio Cecchi 22 Dec '11

22 Dec '11

Hi Timo, I love dovecot but I love also vpopmail and its functions for manage user limits (via vmoduser). Unfortunately in dovecot 1.2.x auth default set to use "vpopmail" is unable to apply this limits. Only if used with checkpassword limits works fine but in the dovecot.log only user (without @domain) is logged. So, based on the code of dovecot 2.0, I have created this very simple patch that correct this bug.

[Dovecot] Backing Up To Windows File Server
by Asai 22 Dec '11

22 Dec '11

Greetings, Working with dsync and setting up backups to a Windows file server. Problem seems to be that Windows is renaming the dovecot mail files (maildir) to Windows friendly filenames, and losing the Dovecot name. For example, 1323817925.M36368P32049.triata.globalchangemultimedia.net,S=2255,W=2318:2,S becomes 1AETPH~X. Does anyone have any ideas about how to tell Windows to not do this? Or is it not possible? -- --asai

[Dovecot] lmtp logging incomplete (does not tell what mailbox mail is actually being saved to!)
by Gary Chodos 22 Dec '11

22 Dec '11

We created a new virtual domain and created a user in that domain in our pgsql database. Instead of creating any directory structure in /home/virtual/mail/<domain>/<user>, I just sent a test email to see if dovecot's lmtp would autocreate. And it did! And mail appears to be delivered to an inbox.. but, logging is weird and I'm not sure everything is working as it should because: Dec 20 23:01:28 mx dovecot: lmtp(21458, user(a)example.com) lUDFG8tZ8U7SUwAAO3tENA: msgid=<20111221040122.GP13367(a)hostname.example.org>: saved mail to . so why doesn't dovecot log where mail is stored/saved? thanks, Gary

[Dovecot] Problem listing SPECIAL-USE flags
by Patrick Ben Koetter 21 Dec '11

21 Dec '11

Timo, we want to implement SPECIAL-USE in Thunderbird (TB), but we've run into problems. I believe you could help change that. Here's the problem: By default TB only lists subscribed (LSUB) folders when it accesses an IMAP server. However when I do a LSUB on recent Dovecot 2.1 code from mercurial I don't get to see the SPECIAL-USE flags. Therefore TB fails to identify which folders it should use and map to until someone tells it to list all folders (LIST) manually. Central part of the SPECIAL-USE idea was/is to require as little user interaction as possible to automatically setup a MUA to do the right thing. Speculating that probably most MUAs will do a LSUB by default and never will get to see SPECIAL-USE flags I think it is easier to have the server-side promote the flags. Do you think that would be possible? Just to verify I configured Dovecot as you would expect for SPECIAL-USE: I've set Dovecot 2.1 to autocreate and autosubscribe SPECIAL-USE mailboxes like this: namespace inbox { ... mailbox AltDrafts { special_use = \Drafts auto = subscribe } ... } This is what I get: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN AUTH=LOGIN AUTH=CRAM-MD5] Dovecot 2.1 ready. t1 login alice(a)example.com secret t1 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS FUZZY SPECIAL-USE] Logged in t2 LSUB "" "%" * LSUB () "."

Method 1 listed in http://wiki.dovecot.org/LDA/Sieve/Dovecot wont work, seems the rpm was build without --enable-header-install Is it sufficient to download the sources from http://archive.ubuntu.com/ubuntu/pool/main/d/dovecot/dovecot_1.2.9.orig.tar… and use them for ./configure --with-dovecot=$path ? thanks and happy holidays julien

[Dovecot] Can I block dovecot from deleting read messages, after being fetched?
by Vasiliu Adrian 21 Dec '11

21 Dec '11

Hi all, Is there an option to disable (server-side) the deletion of read mails after fetching them via POP3, regardless of the MUA config? Here are the issues I'm facing: - my boss wants to force everyone into a server-side "no delete message"-policy, for archiving, auditing and backup&recovery purposes - the requisite here is pop3, so imap is out - the mailusers are virtual users (held in a mysql db) - don't have the budget to set up a separate mail-arvhing server - don't want to use shaggy ways (aka immutable flag, r/w permissions for Maildirs, etc) dovecot --version 2.0.15 Help? Thanks!

After the imap_open() invocation, you should check for error messages in your PHP logs, or dump all the errors using imap_errors(); Without more details, I would say you dropped one of those /option-flags or got the mailbox argument syntax wrong.

[Dovecot] Mail lost - maybe a bug???
by Marco Carcano 21 Dec '11

21 Dec '11

Hello everybody I'm struggling against what seems a really serious trouble: sometimes mail get lost I did all the possible checks, but they seems really lost - I know is absurd, but it seems so it has been noticed by two users on my server: intially I tought that was their mistake (mail deleted, mail into spam, ecc), but it wasn't I deeply checked mail logs, and it seems that mail are delivered (the path is postfix->amavis->dovecotlda) - log files says that messages are delivered, but sometimes we lost a message. I also tried to get into the Maildir and grep the subject of the lost email: if it was addressed to more recipients I'm able to get it on some of them, but not to all (look at the example below) I hope I have clearly explained everything, otherwise let me knowmydomain now an extract from the log file: Oct 27 11:20:29 srv001 postfix/smtpd[24562]: connect from usstlz- psecap06.emerson.com[144.191.128.17] Oct 27 11:20:30 srv001 postfix/smtpd[24562]: CE0B74E4A9F: client=usstlz-psecap06.emerson.com[144.191.128.17] Oct 27 11:20:31 srv001 postfix/cleanup[25157]: CE0B74E4A9F: warning: header Subject: =?utf-8?B?

[Dovecot] APOP and AuthDatabase/SQL
by Peter Smith 21 Dec '11

21 Dec '11

Hi, We're running dovecot 1.2.15 and use SQL authentication. We'd like to be able to support APOP, but can't see how this would fit in with SQL auth. Currently we have: password_query = SELECT email as user, password FROM virtual_users WHERE email='%u' or (email LIKE '%n@%%' AND unhashed='%w') It seems that in order to auth APOP logins, we'd need to access variables containing the authentication string sent by the client, and also variables containing the auth string sent in the POP3 greeting. Incidentally, the RFC (1939) suggests using: <pid.time@hostname> for the greeting, but it looks as if dovecot uses something else? I'm seeing greetings such as: +OK Dovecot ready. <260f.4abcc.4ef11550.cJD6sQSUSnmPS1B/5RGF0Q==(a)myhostname.com> base64 encoding? Thanks in advance, Peter Smith

[Dovecot] Sieve too rfc compliant ;-)
by Jan-Frode Myklebust 20 Dec '11

20 Dec '11

It seems we have a few email addresses that are not RFC 5322 compliant, and now that we've started using sieve these are failing. The problem is that we have a few addresses with leading, trailing or double dots in the local part: jan..frode(a)tanso.net .janfrode(a)tanso.net janfrode.(a)tanso.net I believe these has been working fine with everything else in dovecot (lda, lmtp, imap, pop), but that sieve is more strict. I think it's fair enough that it's strict with messages generated by sieve scripts, but it would be nice if it could be more tolerant with messages addressed for the sieve script. So, is there any setting for making it more tolerant ? -jf

I have tried with doveadm force-resync, maybe this could solve this issues. All of those should be fixed automatically. Do they keep happening if you don't do force-resync? How often do they happen anyway? Do they happen at any specific times (e.g. during doveadm purge)?

Hi, I'm strugling to find some documentation on dovecot's anvil service and/or its penalties (that can be checked with doveadm penalty) ... but i'm not finding anything on that. is there any documentation on anvil/penalties that i should check other than a few messages on the mailing list archive ? thanks ! -- Atenciosamente / Sincerily, Leonardo Rodrigues Solutti Tecnologia http://www.solutti.com.br Minha armadilha de SPAM, NÃO mandem email gertrudes(a)solutti.com.br My SPAMTRAP, do not email it

[Dovecot] Dovecot 2.1rc1 + 2.0.16 woes regarding fts_squat
by Robin 20 Dec '11

20 Dec '11

I can confirm the report posted in http://dovecot.org/list/dovecot/2011-November/062263.html that fts_squat no longer seems to be used after moving from 2.0.16->2.1 rc 1. I don't see crash reports in the logs, just "0 messages indexed". My search test tool just does a normal IMAP SEARCH for a long non-existent string. If there's another way to trigger re-indexing in 2.1, I don't see anything in the documentation for it. I've enabled mail_debug, but no log entries that shed light on the problem are available. Has the configuration for fts_squat changed? If anyone has a working fts_squat setup with Dovecot 2.1rc1, I'd appreciate hearing how you have it setup and working. During a large mail import with 2.0.16 today, I ran across a worrying message in the logs during an fts_squat reindex: out of memory. The plugin doesn't obey the mmap_disable configuration directive, which I've confirmed in the plugin source. The mailbox in question has only 17GB (mdbox style), with about 90,000 emails in it. Its "index" (for the purposes of normal IMAP retrieval as opposed to IMAP TEXT/BODY searching) is fine and uncorrupted. I freshly import these mailboxes between test iterations and any version changes anyway, so if there's corruption, it's happening within dovecot only. I'm using use Mail::IMAPClient to create + append mail over localhost, not any direct mdbox conversion trickery. In looking through the code, I see that mmap() is called for the *ENTIRE FILE*, which is guaranteed to fail on large indexes. I assume this was done out of expedience, but it's a "risky" sort of thing to do in a server process, even if 8GB RAM systems do seem to grow on trees. I intend to put this to work in a large installation (>10K users), so this IS of some concern for me in the long-term.

[Dovecot] doveadm quota does not list all accounts
by Nikolaos Milas 20 Dec '11

20 Dec '11

Hello, I am running dovecot-2.0.13-1_128.el5 x86_64 RPM on CentOS 5.7. All accounts are virtual, hosted on LDAP Server. My problem is that the command: doveadm quota get -A stopped listing all accounts. I think this problem started after I changed in LDAP lookup configuration from "scope = subtree" to "scope = onelevel", because it did not occur before (I did no other changes). Now, the above command only lists 12 accounts. If I query for a particular user: doveadm quota get -u userx this works fine, but userx (and all users except those 12) is NOT listed when trying to display all users. How can I run the above command without problems again? Thanks in advance, Nick

[Dovecot] Quota PostgreSQL INSERT trigger
by Adis Nezirovic 20 Dec '11

20 Dec '11

Wiki instructions for creating insert trigger for PostgreSQL are wrong http://wiki.dovecot.org/Quota/Dict Calling INSERT on the table from within BEFORE INSERT trigger creates cascading trigger. http://www.postgresql.org/docs/current/interactive/trigger-definition.html Instead, one should return NEW record from the trigger, and it will be inserted after trigger execution. --- CREATE OR REPLACE FUNCTION merge_quota2() RETURNS TRIGGER AS $$ BEGIN IF NEW.messages < 0 OR NEW.messages IS NULL THEN -- ugly kludge: we came here from this function, really do try to insert IF NEW.messages IS NULL THEN NEW.messages = 0; ELSE NEW.messages = -NEW.messages; END IF; return NEW; END IF; LOOP UPDATE quota2 SET bytes = bytes + NEW.bytes, messages = messages + NEW.messages WHERE username = NEW.username; IF found THEN RETURN NULL; END IF; BEGIN IF NEW.messages = 0 THEN RETURN NEW; ELSE NEW.messages = - NEW.messages; RETURN NEW; END IF; EXCEPTION WHEN unique_violation THEN -- someone just inserted the record, update it END; END LOOP; END; $$ LANGUAGE plpgsql; DROP TRIGGER IF EXISTS mergequota2 ON quota2; CREATE TRIGGER mergequota2 BEFORE INSERT ON quota2 FOR EACH ROW EXECUTE PROCEDURE merge_quota2(); --- Best regards, Adis

[Dovecot] Tuning Login processes for High-performance Mode
by Alessio Cecchi 20 Dec '11

20 Dec '11

Hi, I'm working for tuning a busy cluster of dovecot servers. Heach server as 4 core, 8GB of RAM and provide POP3 and IMAP access to mailbox. OS is Debian 6.0 and dovecot version is 1.2.15. I am unsure how to set "login_max_processes_count" and "login_max_connections" for reach the best situation when login_process_per_connection is set to no. I don't know what value to set login_max_processes_count. For example is better the first or the second configuration? login_process_per_connection=no login_processes_count=4 login_max_processes_count=8 login_max_connections=512 login_process_size=128 login_process_per_connection=no login_processes_count=4 login_max_processes_count=16 login_max_connections=256 login_process_size=128 Which is a suggested ratio from login_max_processes_count and login_max_connections ? Other values are correct?

[Dovecot] Calculation of suggested vsz_limit values
by Nikolaos Milas 20 Dec '11

20 Dec '11

Hello, I would like to ask on suggested vsz_limit values. Is there any way of calculating such values? How should we determine them? I don't want to risk wrong values (and possible errors) on a production system, if I upgrade to 2.0.16 where vsz_limit values are enforced (I read release notes)! If there is no standard way of calculation, could someone please check the following info and suggest some values? I am running dovecot-2.0.13-1_128.el5 x86_64 RPM on CentOS 5.7 (as a VM on a KVM Host). All accounts are virtual, hosted on LDAP Server. We have about 250 mailboxes of 4GB each (in practice, only a couple of mailboxes ever reach 1GB so we are "over-booking"). It is a relatively low-load server. Memory status and config follows below.

[Dovecot] Strange Login / Timeout Sessions
by Carlos Mennens 20 Dec '11

20 Dec '11

I have my webmail application tied to Postfix / Dovecot server & now for some reason the IMAP sessions oddly time out throughout the day and then logging back into the mail system over the web is painfully slow. The only thing I've seen that fixes it is to reload the Dovecot daemon in Linux: /etc/init.d/dovecot reload Once that command is ran, my webmail login is super fast and moving from folder to folder is extremely fast again. Then in about a few hours, the session will time out and this problem repeats. The problem is the same for everyone and not just a few user accounts. Anyone have any idea what I should be looking for or looking at? My Dovecot logs or mixed in /var/log/maillog which is extremely hard to watch live & gets mixed with Postfix, Amavisd, and Postgrey. Any ideas or suggestions to narrow this problem out? I'm running Dovecot-1.0.7-7.el5_7.1. I saw this load on the console today: Error: Dovecot is already running with PID 2334 (read from /var/run/dovecot/master.pid) Fatal: Invalid configuration in /etc/dovecot.conf Below is my configuration file: [root@mail ~]# dovecot -n # 1.0.7: /etc/dovecot.conf protocols: imap ssl_ca_file: /etc/ssl/certs/digicert.crt ssl_cert_file: ***OMIT*** ssl_key_file: ***OMIT*** login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login mail_location: maildir:~/Maildir auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix

[Dovecot] Two important new Pigeonhole v0.3 features
by Stephan Bosch 19 Dec '11

19 Dec '11

Hello Dovecot users, Pigeonhole v0.3 for Dovecot v2.1 has two new features I would like you to play with before I make a first release: 1) The new Sieve editheader extension (http://tools.ietf.org/html/rfc5293) This allows modifying the headers of the message before delivery. This is actually the first implemented extension that can modify the message itself in any way. This feature adds quite a bit of new code that I'd like to see tested more thoroughly. 2) The new sieve-filter tool (documented in the sieve-filter(1) man page upon installation). This allows (re-)filtering messages that are already stored in a particular mailbox. It preserves the assigned IMAP flags and keywords and using the imap4flags extension these can also be modified. It also plays nice with the editheader extension. Judging by postings in this mailing list from the last few years, this is a highly-demanded feature and I'm glad that I finally got around to finish this thing. If the new sieve-filter tool is lacking certain features in your opinion, just let me know. Needless to say: read the man page carefully and watch out with important mail. This is currently only available from the mercurial repository, but if you prefer to have an .rc1 release first, just tell me and I'll make one. The automatic Debian repository already includes these features. Regards, Stephan.

[Dovecot] IMAP and sieve
by moozer 19 Dec '11

19 Dec '11

I am currently setting up an IMAP server for archiving purposes. The goal is to drag an email to the IMAP folder, and then have a server-side sieve script to put it in the right folder. One of the sources used was this wiki entry http://wiki.dovecot.org/LDA/Sieve/Dovecot I added the mail_plugins = sieve to /etc/dovecot/15-lda.conf and after some exim4 fiddling, mails delivered are filtered by my sieve script. Doing the same for imap delivery (in /etc/dovecot/20-imap.conf) give the following error Dec 19 10:22:09 leon dovecot: imap: Error: dlopen(/usr/lib/dovecot/modules/lib90_sieve_plugin.so) failed: /usr/lib/dovecot/libdovecot-sieve.so.0: undefined symbol: mail_deliver_save_open Dec 19 10:22:09 leon dovecot: imap: Error: Can't load plugin sieve_plugin: Plugin is intended to be used only by binaries: lda lmtp (we're imap) Dec 19 10:22:09 leon dovecot: imap: Fatal: Couldn't load required plugins Dec 19 10:22:10 leon dovecot: imap: Error: dlopen(/usr/lib/dovecot/modules/lib90_sieve_plugin.so) failed: /usr/lib/dovecot/libdovecot-sieve.so.0: undefined symbol: mail_deliver_save_open Dec 19 10:22:10 leon dovecot: imap: Error: Can't load plugin sieve_plugin: Plugin is intended to be used only by binaries: lda lmtp (we're imap) Dec 19 10:22:10 leon dovecot: imap: Fatal: Couldn't load required plugins I notice this part: "plugin is intended to be used only by binaries: lda lmtp (we're imap)" So the question is if it is possible to run sieve server-side sieve scripts on emails copied using IMAP.

[Dovecot] DKIM Verification failures

Hi, -- This message refers to the maillist itself rather than to dovecot software -- I have noticed that when I post to this list (only), I get DKIM Verification failure reports from: root(a)moncton.sidefx.com (e.g. for my last post: "DKIM failure report for job 4D27B5DC4E on mail.sidefx.com") root(a)mail.rmacd.com (e.g. for my last post: "DKIM failure report for job B69B3187F1 on mail.rmacd.com") root(a)mx0.roessner-net.de (e.g. for my last post: "DKIM failure report for job 6103B52092 on mx0.roessner-net.de") I have not had other DKIM failure reports from anywhere and I know that we should not have issues with it.

[Dovecot] simultaneous scripts not running via sieve_before
by Scott Lewis 16 Dec '11

16 Dec '11

Hi again everyone, So I've finally got sieve integration happening on my REHL Postfix/Dovecot server, with private user scripts happily running when users create them. (we user SquirrelMail, so the avelsieve plugin runs the sieve integration). Now I'd like to utilise additional per-user scripts (probably via sieve_before), but I've not been able to get my additional scripts to execute. I am doing the following: a) getting avelsieve to write my redirect script (ie. logging on as user, completing private script wizard, and activating it) b) compiling .dovecot.sieve with sievec c) copying the resultant .dovecot.svbin to sieve/ directory (and renaming it eg redirect.svbin still, it appears that each /home/%u/.dovecot.sieve file is the only one taking effect. Any thoughts on how to make the other ones active? (The idea behind this is to automatically forward all of joeuser@mydomain's incoming mail to somewhere like joeusersbackup(a)gmail.com, for backup reasons. One day, I'll work out how to configure postfix to do this for all outgoing email too, but that's for another day :) Below are what my .conf files look like. Thanks in advance, Scott /etc/dovecot.conf: [code] protocols = imap imaps managesieve listen = * protocol imap { #mail_plugins = sieve quota } ## ## ManageSieve specific settings ## protocol managesieve { # debugging mail_debug = yes #login_executable = /usr/libexec/dovecot/managesieve-login #mail_executable = /usr/libexec/dovecot/managesieve #managesieve_max_line_length = 65536 #managesieve_logout_format = bytes ( in=%i : out=%o ) #managesieve_implementation_string = Cyrus timsieved v2.2.13 } protocol lda { mail_plugins = sieve quota sieve=~/.dovecot.sieve sieve_extentions = +include sieve_dir=~/sieve sieve_before = /home/%u/sieve/redirect.svbin sieve_global_path = /etc/globalsieverc.svbin [/code]

[Dovecot] Quota warnings not being sent

14 Dec '11

Hello, I am running dovecot-2.0.13-1_128.el5 x86_64 RPM on CentOS 5.7 with the config shown below. All accounts are virtual, hosted on LDAP Server. My problem is that the quota warning mail is not sent as expected. For example, in the logs I get: Dec 12 08:42:40 vmail dovecot: lda(imaptester): Error: quota: net_connect_unix(/var/run/dovecot/quota-warning) failed: Permission denied (euid=500(vmail) egid=500(vmail) missing +r perm: /var/run/dovecot/quota-warning, euid is not dir owner) Here is /var/run/dovecot/: # ls -la /var/run/dovecot/ total 32 drwxr-xr-x 4 root dovecot 4096 Dec 9 21:27 . drwxr-xr-x 23 root root 4096 Dec 14 12:27 .. srw------- 1 root root 0 Dec 9 21:27 anvil srw------- 1 root root 0 Dec 9 21:27 anvil-auth-penalty srw------- 1 root root 0 Dec 9 21:27 auth-client srw------- 1 dovecot root 0 Dec 9 21:27 auth-login srw-rw---- 1 vmail vmail 0 Dec 9 21:27 auth-master srw------- 1 root root 0 Dec 9 21:27 auth-userdb srw------- 1 dovecot root 0 Dec 9 21:27 auth-worker srw------- 1 root root 0 Dec 9 21:27 config srw------- 1 root root 0 Dec 9 21:27 dict srw------- 1 root root 0 Dec 9 21:27 director-admin srw-rw-rw- 1 root root 0 Dec 9 21:27 dns-client srw------- 1 root root 0 Dec 9 21:27 doveadm-server lrwxrwxrwx 1 root root 25 Dec 9 21:27 dovecot.conf -> /etc/dovecot/dovecot.conf drwxr-xr-x 2 root root 4096 May 17 2011 empty drwxr-x--- 2 root dovenull 4096 Dec 9 21:27 login -rw------- 1 root root 5 Dec 9 21:27 master.pid srw------- 1 root root 0 Dec 9 21:27 quota-warning Follows my config (at the end of this message).

[Dovecot] Two recent issues
by Brad Schuetz 14 Dec '11

14 Dec '11

I've been using dovecot for years, been working great. However recently I've come across two issues. The first issue unfortunately I have little information on, mail_debug hasn't provided anything useful either (in fact it looks like the login request that fails doesn't even get logged at all). During the morning rush of email, this server has around 11k mailboxes on it, it *appears* that one of the auth processes dies resulting in "dovecot: imap-login: Error: read(imap) failed: Connection reset by peer" errors followed by "dovecot: imap-login: Internal login failure ..." in the logs. I've yet to get any useful debugging information on this error so I'm not expecting much/any help on this one, but if anyone has any ideas on how I can get more debug besides running strace 24/7 in the hopes it catches something before the hard drive is full of strace output I'd love to hear it. The best I've gotten was a lucky strace once (at the time I didn't realize it was so lucky or I would have saved the output) that indicated the imap-login daemon was failing to connect to the auth process. The second issue is lmtp/lda (tried both) delivery to a mailbox that has filesystem quotas enabled and the group quota is maxed is resulting in the below panic and crash. This issue happens with 2.0.13, 2.0.15 and 2.0.16. Here's the logs showing that it knows the disk quota is exceeded and then a subsequent zlib panic. Like it's trying to deliver it anyway. --------------------- 11:21:07 [err] dovecot: lmtp(29691, admin(a)[redacted].com) Error: o_stream_send_istream(/email/d/r/[redacted]/[redacted]/admin/Maildir/tmp/1323458467.M245978P29691.fenrir.omnis.com) failed: Disk quota exceeded 11:21:07 [crit] dovecot: lmtp(29691, admin(a)[redacted].com) Panic: file ostream-zlib.c: line 144 (o_stream_zlib_send_flush): assertion failed: (zs->avail_in == 0) 11:21:07 [err] dovecot: lmtp(29691, admin(a)[redacted].com) Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0 [0x345443ca90] -> /usr/lib64/dovecot/libdovecot.so.0 [0x345443cae6] -> /usr/lib64/dovecot/libdovecot.so.0 [0x345443c4a3] -> /usr/lib64/dovecot/lib20_zlib_plugin.so [0x2ba2d31547f6] -> /usr/lib64/dovecot/lib20_zlib_plugin.so [0x2ba2d315481b] -> /usr/lib64/dovecot/libdovecot.so.0(o_stream_flush+0x2a) [0x345444f0ea] -> /usr/lib64/dovecot/libdovecot-storage.so.0(maildir_save_finish+0x6b) [0x3451c63b6b] -> /usr/lib64/dovecot/lib10_quota_plugin.so [0x2ba2d2f4ce7a] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mailbox_save_finish+0x30) [0x3451c2fbb0] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mail_storage_copy+0xb3) [0x3451c2aae3] -> /usr/lib64/dovecot/libdovecot-storage.so.0(maildir_copy+0x56) [0x3451c6fd36] -> /usr/lib64/dovecot/lib10_quota_plugin.so [0x2ba2d2f4d0ba] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mailbox_copy+0x5a) [0x3451c301ba] -> /usr/lib64/dovecot/li 11:21:07 [err] dovecot: master: Error: service(lmtp): child 29691 killed with signal 6 (core dumps disabled) --------------------- Attached is the current "doveadm config" output. -- Brad Schuetz

Re: [Dovecot] Questions about single intance storage
by Maria Arrea 13 Dec '11

Hello Timo. If we can not safely restore from backup a user's mailbox with SiS enabled, we can not enable SiS. Any plan to include this backup recovery tool in dovecot 2.0.X or 2.1? Regards Maria > 5º We use bacula to save indexes & mdboxes, and we recover mailboxes using doveadm import when a user "makes a fatal mistake" wiping all her Inbox. If we enable SiS I am not really sure how can we safely restore a user's INBOX if that user has SiS attachments. Hm. Yes, that is problematic.. Even if you knew what SIS files were used, there's no simple way to restore those with proper refcounts. I think what really should be done is writing a tool that can create/restore backups, possibly de-SISing the attachments..

[Dovecot] Saving archive copy of all mail sent/received w/Dovecot+Postfix?
by Andrew M 12 Dec '11

12 Dec '11

I'm running Dovecot 2.0.15 and Postfix 2.7.7 with postfix handing off to Dovecot's LDA. I am hosting multiple virtual domains with multiple users and everything is working. I would now like to create a permanent archive of all sent/received mail with each virtual user's mail saved to its own sent file and received file. This needs to be independent of the user's regular Maildir store since he can't delete or modify the permanent archive. Any suggestions on how to best accomplish this either via postfix or dovecot? Postfix has in main.cf virtual_transport = dovecot and in master.cf dovecot unix - n n - - pipe flags=DRhu user=virtual:virtual argv=/usr/libexec/dovecot /dovecot-lda -d ${recipient} -f ${sender} dovecot uses this: [root@xxx andrew]# dovecot -n # 2.0.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.35.14-103.fc14.x86_64 x86_64 Fedora release 14 (Laughlin) ext4 auth_mechanisms = plain login cram-md5 disable_plaintext_auth = no mail_location = maildir:/home/vmail/%d/%n/Maildir mbox_write_locks = fcntl passdb { args = scheme=plain username_format=%u /etc/postfix/passwd driver = passwd-file } protocols = imap lmtp service auth { inet_listener { port = 12345 } unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { mode = 0666 } } ssl_cert = </etc/pki/tls/certs/xxx.com.crt ssl_key = </etc/pki/tls/private/xxx.com.key userdb { args = username_format=%u uid=5000 gid=5000 home=/home/vmail/%d/%n driver = static } Thanks, Andrew

[Dovecot] mail_max_userip_connections=10
by Tom Clark 12 Dec '11

12 Dec '11

Hi, A couple of questions rather than a problem for once! We've got our Dovecot server running smoothly now apart from our MD. He's having problems with mail_max_userip_connections. He has 3 (Phone/Laptop/Tablet) items that all connect to the server at about the same time. Which means he's frequently running over the max_userip_connections. My questions are: Is there anyway of whitelisting an IP so that it can ignore mail_max_userip_connections=10? What should we set mail_max_userip_connections too realistically? 10 seems a bit low? Thanks Tom

[Dovecot] question regarding postfixadmin
by oni-neko＠gmx.net 12 Dec '11

12 Dec '11

Hello! I hope someone here is already using postfixadmin with dovecot and can help me out =) the install-readme for postfixadmin mentions, that the mail-home should be set to default_mail_env = maildir:/var/mail/vmail/%u/ but my dovecot is already installed and working with another config, namely mail_location = maildir:/var/dovecotmail/%n/Maildir. Do i have to change this, or is postfixadmin able to read this or can i set this value in postfixadmin somewhere? i´d rather avoid moving all mailfolders around just because of that, and unfortunately the paths don´t really lend themself to an easy solution via symlink ^_^ thanks for any replies best regards sil -- Empfehlen Sie GMX DSL Ihren Freunden und Bekannten und wir belohnen Sie mit bis zu 50,- Euro! https://freundschaftswerbung.gmx.de

[Dovecot] Documentation clarifiction on mmap_disable

Greetings, On http://wiki.dovecot.org/MainConfig I read: "mmap_disable = no Don't use mmap() at all. This is required if you store indexes to shared filesystems (NFS or clustered filesystem). " Does that mean: 1. mmap is required when using NFS or 2. it is required to don't use mmap at all when using NFS? Sorry if this is obvious. Best regards. -- *Marcio Merlone*

[Dovecot] database failover
by Nick Edwards 12 Dec '11

12 Dec '11

Trying to get dovecot to _only_ use local copy of database, only querying another database server (same database, just replicated) if local copy is not responding, I have google fu'd a bit and found my only answer in so far as dovecot did this once upon as time, but it was only due to a dovecot bug, that has since been fixed, is that so? The wiki shows no information of failover, just load sharing, or is it an undocumented feature, or can dovecot not do failover, if not, can it be made so? Trying to cut down on network traffic, postfix does this nicely, I thought dovecot did too.

With 2.0.16 hdr.xxx fields get copied fine (but of course without timestamp). With the patch you provided they don't get copied whether using mirror or backup & starting from scratch. I'm doing a Maildir to sdbox migration otherwise don't think I'm doing anytihng strange. Mark ________________________________________ From: Mark Zealey Sent: 08 December 2011 09:35 To: Timo Sirainen Cc: Dovecot Mailing List Subject: RE: [Dovecot] using dsync to convert mailboxes looses caching options OK I'll test the header copying more fully. The reason we want to preserve caching decisions is to avoid an IO storm when users log in to their mailboxes after an sdbox upgrade so it would be great to be able to have some way to warm caches.

[Dovecot] using dsync to convert mailboxes looses caching options
by Mark Zealey 10 Dec '11

10 Dec '11

Hi there, We're trying to convert users from Maildir to sdbox at present; I'm using dsync to achieve this (2.0.16) however when the user's have been converted we only get minimal information in the caching files. Is there some way to preserve all the caching decisions that were previously made so that when the user logs in to the new mailbox we don't have to cause an io storm rebuilding the cache that we know was good? Dovecot seems to be partially doing this - if i remove the logs/cache from the source mailbox no cache files are built in the conversion; if i put them back then we get a cache file built but it only contains a few bits of information (guid, date.save). Looking into this a bit further i find that when the caches are present at source the fields are preserved but the 'last used' date and caching decisions are not which I suspect means dsync doesn't bother caching on import - only fields with a yes decision in the source are copied (but their decision is only copied as a tmp with the date of import). For example: Source idxview cache: -- Cache fields -- # Name Type Size Dec Last used 0: flags bit 4 tmp 2011-11-25 16:09 1: date.received fix 4 yes 2011-11-26 16:17 2: size.virtual fix 8 tmp 2011-11-25 16:09 3: imap.bodystructure str - tmp 2011-11-25 16:09 4: mime.parts var - tmp 2011-11-25 16:09 5: hdr.IMPORTANCE hdr - tmp 2011-11-25 16:09 6: hdr.X-PRIORITY hdr - tmp 2011-11-25 16:09 7: hdr.CONTENT-TYPE hdr - tmp 2011-11-25 16:09 ... 18: date.sent fix 8 no 1970-01-01 01:00 19: date.save fix 4 yes 2011-11-26 16:17 20: size.physical fix 8 no 1970-01-01 01:00 21: imap.body str - no 1970-01-01 01:00 ...

[Dovecot] POP - preventing re-download with server move
by Trutwin, Joshua 10 Dec '11

10 Dec '11

Hi, Curious if anyone has any good suggestions to handle this. I try to get my hosting users to use IMAP but most use Outhouse and the IMAP support is somewhat annoying for many so I typically have them change their settings when using POP to leave copies on the server. That way when they get the inevitable virus or wanna use webmail they have a backup copy and webmail sees their saved mail. So now I have to move my sites to a new server and I'm trying to avoid having all these messages re-downloaded by POP clients. Some of the sites I've moved with low email usage have just dealt with the re-download and cleaned up afterwards. I have a few other accounts though that I'm more concerned about that have massive amounts of stored email. The mail is stored in Maildirs - a sample file: 1280409166.23580.foo:2,S If I move this to server "bar" would renaming the file to 1280409166.23580.bar:2,S prevent this somehow? Old server uses qmail-pop, new server uses dovecot 2.0. Thanks for any tips, Josh

[Dovecot] noaclright
by Knud Dombrowsky 10 Dec '11

10 Dec '11

Hi, I recently upgraded to openSuse 12.1 which comes with dovecot 2.0.14. Because of mail-client-problems I am running one dovecot which requires authentication via a client-certificate and another one which can be used without a certificate. (Configurations can be found below.) Since the upgrade our shared mailbox is no longer visible. I tried to repair this by setting the ACLs once again (using imap-acl in Thunderbird) but every time I try to set a new ACL the tool says "noaclright" and dovecot logs the following messages: Dec 7 14:31:14 mailbox dovecot: imap(<sharing-user>): Error: fstat(/home/<sharing-user>/Maildir/.<shared-folder>/dovecot-acl.lock) failed: No such file or directory Dec 7 14:31:14 mailbox dovecot: imap(<sharing-user>): Error: file_dotlock_open(/home/<sharing-user>/Maildir/.<shared-folder>/dovecot-acl) failed: No such file or directory Needless to say the file exists and its contents looks like it should. (Every line is an ACL like "user=testuser ilrws") I took a look at the changelog from 2.0.14 onwards and since it says nothing about my problem I am not looking forward to compiling dovecot myself and installing it. Any ideas why this is happening? Is this a known problem?

[Dovecot] overriding userdb connection host for doveadm-user
by Micah Anderson 10 Dec '11

10 Dec '11

I've got my users in a replicated database setup and dovecot configured with two connect lines in dovecot-sql.conf: connect = host=127.0.0.1 port=3306 dbname=users user=user password=pass connect = host=127.0.0.2 port=3306 dbname=users user=user password=pass this works really well to help balance the load. However, when a new user is created, the replication information sometimes has not made it to the slave database before my user creation process tries to send that new user an email about their new email account. If it hasn't and the email gets sent, then it bounces because postfix thinks the user doesn't exist yet. Replication usually happens within seconds, but could be delayed due to problems. I would like a way to see if the new user's information has been replicated yet before sending the email. I was thinking I could use 'doveadm user' to lookup the user, but I am not sure that I can specify one of the specific 'connect' lines in my configuration to check. Is there a way to override that configuration variable to do this test? I tried various incarnations of passing '-o connect=host='... but doveadm user would just ignore them. thanks for any suggestions! micah ps - yes, I can make my user creation process just 'sleep' for an arbitrary amount of time and by that time the replication should have occured, but that is a bit of a shot in the dark, and doesn't handle longer replication delays that could potentially happen. --

[Dovecot] Make entire mailbox read-only (ACLs?)
by David Jonas 10 Dec '11

10 Dec '11

Hello, Is there a way of locking a mailbox, effectively making it read-only to IMAP clients? I've read through http://wiki2.dovecot.org/ACL. I created dovecot-acl with the content "owner lr" in .INBOX which seems to keep me from copying messages into the folder, but not out. I have the plugin configured correctly, it seems, since MYRIGHTS command shows the correct value: 30 MYRIGHTS "INBOX" * MYRIGHTS "INBOX" lr Am I barking up the wrong tree? Is there an easier way to lock a mailbox? post-login scripting perhaps? Thanks!

[Dovecot] Major bug with hardlinks and lmtp
by Brad Schuetz 10 Dec '11

10 Dec '11

In working on trying to fix the crash issue from my last email I had enabled LMTP delivery to try it out instead of using the LDA. I have discovered that when a single piece of email is to be delivered to multiple users the message is being hard linked instead of copied into each mail box. This is a major problem that makes LMTP unusable in an environment where each mailbox has it's own UID since the hard linked file will only be readable by one of the users.

[Dovecot] Wish list item: %g/%{gid} variable
by Pascal Volk 09 Dec '11

09 Dec '11

I think it would be very useful to have a user's GID in a variable. So i could use for example: mail_attachment_dir = /srv/mail/.SiS/%{gid} I use one GID per domain and the aliases fqhns of the domain. When for example example.com would be an alias for exmaple.net (gid: 12345), the attachments would be stored inside /srv/mail/.SiS/12345/, no matter if a message was sent to john.doe(a)example.com or to john.doe(a)example.net. "quota = dict:domain:%{gid}:proxy::quota" would then also work. Regards, Pascal -- The trapper recommends today: c01dcofe.1134217(a)localdomain.org

[Dovecot] "Unstable" vs "Development" vs "Nightly"
by Terry Carmen 09 Dec '11

09 Dec '11

I'm currently running v2.1rc1, but have been seeing errors like: Dec 8 11:31:55 it kernel: auth[18914]: segfault at 48 ip 00fe2f74 sp bfcaccd0 error 4 in libauthdb_imap.so[fdd000+f000] The unstable and nightly builds are newer, but are they likely to be more or less stable than the version I'm currently running? I'd like to install a newer version, but am trying to get a feel for how usable they're likely to be. Thanks, Terry

[Dovecot] Error: Corrupted index cache file /xxx/yyy/zzz/indexes/.INBOX/dovecot.index.cache: invalid record size
by florent＠coppint.com 09 Dec '11

09 Dec '11

Hi all, I got a problem with a Dovecot IMAP/POP installation. Since a recent failure of our distributed file system (no loss of data btw), Dovecot seems to have a problem with index cache files. For a lot of accounts, I have this error in logs: Error: Corrupted index cache file /xxx/yyy/zzz/indexes/.INBOX/dovecot.index.cache: invalid record size If I delete all files from /indexes/ directory, it still occurs... Do you see what can cause this problem ? Or what information can I provide to help ? Our distributed FS is MooseFS. Dovecot is configured like if it was NFS (no mmap, etc...). Thank you for your help :) Flo

Thanks Timo, this patch applied clean against 2.0.16 just running it on live for the past few minutes & seems to have fixed the issues.

[Dovecot] problems when using dsync between servers
by Yann Dupont 08 Dec '11

08 Dec '11

Hello, I'm trying to migrate from maildir++ to mdbox. The maildir++ is a leftover of our previous setup (was using courier) We have 3 virtuals servers for our +70000 accounts. Now, I'd like to use mdbox, so I'm trying using dsync for that. I setup a new virtual server, configured for mdbox. 1st, I tried a basic setup: I established a file with all my accounts (taken from LDAP) and then I use this script : FILENAME=$1 while read LINE do dsync -u $LINE backup $LINE@my_new_server done < $FILENAME But it's quite slow and dsync hangs. So I tried another approach using multi threaded python. Much faster (using all the cores), but dsync still hangs on some accounts. After a certain time dsync exit with an error like that : Panic: file dsync-worker-local.c: line 1688 (local_worker_save_msg_continue): assertion failed: (ret == -1) dsync-remote(E072184L): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x3fd8a) [0x7f34fc577d8a] -> /usr/lib/dovecot/libdovecot.so.0(default_fatal_handler+0x32) [0x7f34fc577e72] -> /usr/lib/dovecot/libdovecot.so.0(i_error+0) [0x7f34fc55119f] -> dsync() [0x40ff0b] -> dsync() [0x410142] -> dsync(dsync_worker_msg_save+0x99) [0x40f639] -> dsync() [0x40e24a] -> dsync() [0x40d8ef] -> dsync() [0x40dbfc] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x48) [0x7f34fc5830d8] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x9f) [0x7f34fc58403f] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x28) [0x7f34fc583068] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f34fc5713a3] -> dsync(main+0x9e1) [0x4078b1] -> /lib/libc.so.6(__libc_start_main+0xfd) [0x7f34fbde9c4d] -> dsync() [0x406cf9] This is on a RUNNNING server. My aim was to make some pass on the running server, then stop it and make a last pass to finish the process. Is dsync supposed to run only on a stopped server ? Is my approach totally wrong ? -- Yann Dupont - Service IRTS, DSI Université de Nantes Tel : 02.53.48.49.20 - Mail/Jabber : Yann.Dupont(a)univ-nantes.fr

[Dovecot] sql dict: commit failed: MySQL server has gone away
by Mark Zealey 08 Dec '11

08 Dec '11

Following on from this thread: http://www.dovecot.org/list/dovecot/2010-September/052704.html <https://owa2010.webfusion.com/owa/redir.aspx?C=a447887e3d204944a8c766142df4…> in 2.0.16 I am seeing the same issues. I believe this would be related to some timeouts set on our mysql servers which are pretty low (30 or 60 seconds or so to drop idle connections). This is happening for imap, pop and lmtp processes when they try to update quotas stored in a mysql database; presumably it is the dict process that actually has these issues - the lmtp delivery isn't lasting longer than 1 second so shouldn't be seeing any timeouts there. This is always followed by the "Error: dict quota: Quota update failed, it's now desynced" line; presumably it is telling the truth but I'm not sure how I could tell. We are also seeing this "MySQL server has gone away" issue in login processes but it isn't causing an issue there as presumably dovecot transparently retries rather than just giving up as it seems to in the quota updates. Any thoughts or advice would be appreciated. Mark

Hi, I'm building a Postfix/Dovecot mail server and while I am able to send/receive emails using telnet, after establishing a connection to Dovecot via a client (Mail Live, Thunderbird etc) the following appears in the logs: Nov 28 14:11:02 mailserver dovecot: [ID 583609 mail.info] pop3-login: Login: user=<user(a)domain.com>, method=PLAIN, rip=xxx.xxx.xxx.xxx, lip=xxx.xxx.xxx.xxx, mpid=282 78 Nov 28 14:11:02 mailserver dovecot: [ID 583609 mail.error] master: Error: service(pop3-login): child 28277 killed with signal 10 (core not dumped - set service pop3-log in { drop_priv_before_exec=yes }) Nov 28 14:11:02 mailserver dovecot: [ID 583609 mail.info] pop3(user(a)domain.com): Disconnected: Logged out top=0/0, retr=0/0, del=0/5, size=3250 I also experience very poor connectivity to the server, with Microsoft Mail and Thunderbird regularly failing to connect (connection errors in the client and no login attempt in the dovecot logs).

Is it possible to specify more than one backend-server IPs as I can do for the database hosts for userdb queries?

[Dovecot] doveadm fetch vs search+fetch
by Joseph Tam 08 Dec '11

08 Dec '11

What's the pactical difference between using "doveadm fetch" rather than using "doveadm search" in conjunction with "doveadm fetch", as the man pages suggest? It seems "doveadm fetch" functionally supercedes "doveadm search" making the latter obsolete. It can even be closely simulated with "doveadm -f tab fetch ... 'mailbox-guid uid' search-query ...".

[Dovecot] IMAP SPECIAL-USE extension
by Timo Sirainen 07 Dec '11

07 Dec '11

It's implemented now in dovecot-2.1 hg. It also deprecates autocreate plugin (but it still works the old way). The idea is that you can now do e.g.: mailbox Trash { auto = no special_use = \Trash } mailbox Drafts { auto = no special_use = \Drafts } mailbox Sent { auto = subscribe # autocreate, autosubscribe special_use = \Sent } mailbox Spam { auto = create # autocreate, but don't autosubscribe special_use = \Junk } mailbox virtual/All { # if you have a virtual "All messages" mailbox auto = no special_use = \All } The mailbox names require a namespace prefix, so if you use e.g. "INBOX." prefix you'll need to use: mailbox INBOX.Trash { ..etc..

[Dovecot] MS Exchange IMAP Proxy

I need to make the IMAP interface of an Exchange 2000 server available on the net, however I would like to give it a little protection, and believe Dovecot's IMAP proxy might be appropriate. Does anybody have a *really simple* config that would allow IMAP pass-through to a single Exchange server? The examples I've seen all assume some sort of load balancing, which isn't an issue here, so I'd like to eliminate the need for an unnecessary database server. Does Dovecot do any cleanup of the IMAP commands that would be useful in protecting Exchange (from this, http://www.cvedetails.com/cve/CVE-2007-0221/ for example), or am I barking up the wrong tree? If Dovecot isn't helpful for this, can anybody point me to a better resource? Thanks! Terry

[Dovecot] Strange quota problem

05 Dec '11

I have a strange problems with quota on v2.0.14. We have an ldap user directory, and all users should have a mailQuota defined there. My problem is that some users gets the quota enforced, while others don't, and "doveadm user" doesn't seem to agree with "doveadm quota ge gett" Ref: $ doveadm user janfrode(a)example.net userdb: janfrode(a)example.net home : /usr/local/atmail/users/j/a/janfrode(a)example.net mailQuota : quota_rule=*:storage=2100000 $ doveadm -f tab quota get -u janfrode(a)example.net Quota name Type Value Limit % UserQuota STORAGE 760 1000000 0 UserQuota MESSAGE 62 - 0 Why limit 1000000 instead of 2100000 ? $ doveadm user omar(a)example.net userdb: omar(a)example.net home : /usr/local/atmail/users/o/m/omar(a)example.net mailQuota : quota_rule=*:storage=1000000 $ sudo doveadm -f tab quota get -u omar(a)example.net Quota name Type Value Limit % UserQuota STORAGE 0 - 0 UserQuota MESSAGE 0 - 0 $ doveadm user testkunde(a)example.net userdb: testkunde(a)example.net home : /usr/local/atmail/users/t/e/testkunde(a)example.net mailQuota : quota_rule=*:storage=1000000 $ doveadm -f tab quota get -u testkunde(a)example.net Quota name Type Value Limit % UserQuota STORAGE 33918 - 0 UserQuota MESSAGE 137 - 0 Why no storage limit ?

[Dovecot] Dovecot crash non stop: "uid 0: exited on signal 11"
by Amaury Le Pivain 05 Dec '11

05 Dec '11

Hi all, I have an old physical freebsd 6.2 server running Dovecot 1.0.7. I wanted to virtualised it. So, I did a dd from the physical server and then I restored it on then now Virtual Machine. I booted the server, all services are running just fine excepted Dovecot. I tried to investigate the log as much as I can but i'm not getting any usefull pieces of information. The only entries I have in the log files are the following: /*log: /var/log/messages:*/ /Dec 5 09:53:35 hostname kernel: pid 33815 (imap), uid 0: exited on signal 11 Dec 5 09:53:39 hostname kernel: pid 33820 (imap), uid 0: exited on signal 11 Dec 5 09:54:22 hostname kernel: pid 33910 (pop3), uid 0: exited on signal 11 Dec 5 09:55:22 hostname kernel: pid 34071 (pop3), uid 0: exited on signal 11 Dec 5 09:55:47 hostname kernel: pid 34103 (imap), uid 0: exited on signal 11 Dec 5 09:56:13 hostname kernel: pid 34143 (pop3), uid 0: exited on signal 11 Dec 5 09:56:21 hostname kernel: pid 34164 (pop3), uid 0: exited on signal 11 Dec 5 09:56:26 hostname kernel: pid 34180 (imap), uid 0: exited on signal 11 Dec 5 09:56:40 hostname kernel: pid 34201 (imap), uid 0: exited on signal 11 Dec 5 09:56:49 hostname kernel: pid 34227 (imap), uid 0: exited on signal 11/ /*log: /mail/log/dovecot.log:* dovecot: Dec 05 10:13:46 Info: imap-login: Login: user=<test-amaury(a)mydomain.com>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured dovecot: Dec 05 10:13:46 Error: child 36621 (imap) killed with signal 11/ I'm also running a squirrelmail as a webmail and here when I refresh a folder content 3/5 times I'm getting an error: /Error: Connection dropped by IMAP server Query: SELECT "INBOX.Corbeille"/ I'm using Dovecot version 1.0.7 on a freebsd 6.2 and my dovecot.conf is: dovecot -n /# 1.0.7: /usr/local/etc/dovecot.conf base_dir: /mail/ log_path: /mail/log/dovecot.log protocols: imap pop3 ssl_disable: yes disable_plaintext_auth: no login_dir: /mail//login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login login_greeting: POP3/IMAP ready. verbose_proctitle: yes first_valid_gid: 0 mail_extra_groups: mail mail_location: maildir:~/Maildir fsync_disable: yes maildir_copy_with_hardlinks: yes mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota trash mail_plugins(imap): quota imap_quota trash mail_plugins(pop3): quota mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 imap_client_workarounds(default): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: default_realm: tropik.nc passdb: driver: sql args: /usr/local/etc/dovecot-sql.conf userdb: driver: sql args: /usr/local/etc/dovecot-sql.conf socket: type: listen master: path: /mail/auth-master mode: 384 user: vmail group: vmail plugin: quota: maildir trash: /usr/local/etc/dovecot-trash.conf/ Thank you for your help!
