[Dovecot] v.1.2.4 deliver maildir quota does not work
by myleetlist＠gmx.de 14 Sep '09

Hi, I'm using deliver for storing new mails (nfs). Since v.1.2 deliver does not reject mails if over quota (maildir quota). test with v. 1.1.18: # HOME=/tmp/maildir/ /path/dovecot-1.1.18/libexec/dovecot/deliver -e -c /path/dovecot-1.1.18/etc/dovecot.conf # Quota exceeded (mailbox for user is full) test with v. 1.2.4: # HOME=/tmp/maildir/ /path/dovecot-1.2.4/libexec/dovecot/deliver -e -c /path/dovecot-1.2.4/etc/dovecot.conf -> mail is saved to INBOX so where is the problem? what am I doing wrong? greets, Walter. # cat maildirsize 250S 8399 21 46 1 log output with mail_debug = yes: deliver(User): Loading modules from directory: /path/dovecot-1.2.4/lib/dovecot/lda deliver(User): Module loaded: /path/dovecot-1.2.4/lib/dovecot/lda/lib10_quota_plugin.so deliver(User): Module loaded: /path/dovecot-1.2.4/lib/dovecot/lda/lib90_sieve_plugin.so deliver(User): Quota root: name=User quota backend=maildir args= deliver(User): Namespace: type=private, prefix=INBOX., sep=., inbox=yes, hidden=no, list=1, subscriptions=yes deliver(User): maildir: data=/tmp/maildir/:INDEX=MEMORY deliver(User): maildir++: root=/tmp/maildir, index=, control=, inbox=/tmp/maildir deliver(User): sieve: local script path /tmp/maildir/filter.sieve doesn't exist (using global script path in stead) deliver(User): sieve: user has no valid personal script deliver(User): sieve: no scripts to execute: reverting to default delivery. deliver(User): Namespace INBOX.: Using permissions from /tmp/maildir: mode=0700 gid=-1 deliver(User): msgid=: test () - saved mail to INBOX # 1.2.4: /path/dovecot-1.2.4/etc/dovecot.conf # OS: Linux 2.6.18-92.1.22.el5 i686 CentOS release 5.2 (Final) log_timestamp: %Y-%m-%d %H:%M:%S protocols: none ssl: no verbose_proctitle: yes mail_gid: 6 mail_location: maildir:%h:INDEX=MEMORY mmap_disable: yes mail_nfs_storage: yes mail_nfs_index: yes maildir_copy_preserve_filename: yes namespace: type: private separator: . prefix: INBOX. location: maildir:%h:INDEX=MEMORY inbox: yes list: yes subscriptions: yes lda: postmaster_address: postmaster@... mail_location: maildir:%h:INDEX=MEMORY mail_plugins: quota sieve deliver_log_format: msgid=%m: %f (%s) - %$ auth default: passdb: driver: pam userdb: driver: passwd userdb: driver: static args: allow_all_users=yes gid=6 sieve=%hfilter.sieve plugin: quota: maildir:User quota sieve: %hfilter.sieve -- GRATIS für alle GMX-Mitglieder: Die maxdome Movie-FLAT!

[Dovecot] Dovecot upgrade from 1.0.7-7.el5 to 1.2.4 ?
by Eero Volotinen 12 Sep '09

12 Sep '09

I am currently using dovecot 1.0.7-7.el5 on 32bit centos. Plan is to upgrade to 1.2.4 using http://atrpms.net/dist/el5/dovecot/ rpms. My config is very minimal: protocols = imaps imap ssl_cert_file = /etc/pki/tls/certs/server.cert ssl_key_file = /etc/pki/tls/private/server.key ssl_cipher_list = HIGH:MEDIUM:+TLSv1:!SSLv2:+SSLv3 mail_location = maildir:~/Maildir protocol imap { } protocol pop3 { } auth default { mechanisms = plain login passdb pam { } userdb passwd { } user = root socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } Just wondering if 1.0 to 1.2.4 is safe, or do I need to upgade to 1.1 first? Thanks, Eero

[Dovecot] Question about the pop3 feature "leave messages on server for a certain period of time"
by Δημήτριος Καραπιπέ ρης 12 Sep '09

12 Sep '09

Hi all I am missing something on the the pop3 "leave messages" rationale. Although the UIDL feature solves for the MUA the problem "whch mails should be downloaded", how the duration that these mails should be kept on server, say 10 days for one MUA and 20 days for another MUA for the same account, is resolved on the server? thanks in advance -- ΔΗΜΗΤΡΙΟΣ ΚΑΡΑΠΙΠΕΡΗΣ ΤΕΧΝ.

[Dovecot] Sieve, vacation, variables and russian language
by Sergey Grigorian 12 Sep '09

12 Sep '09

Folks, I'm using a Sieve script for vacation messages and there's something strange with it in certain cases. The script uses the "variables" extension to produce the "Re: [original subject] (autoreply)" subject line for the vacation message. All is well except for cases when that [original subject] is written in Russian. In those cases the subject string is garbled, and the Amavis content filter says "X-Amavis-Alert: BAD HEADER SECTION, Non-encoded 8-bit data (char D0 hex):Subject: RE: \320\277\321?\320\276\320\261\320\260 (Auto[...]" It doesn't complain about English subject strings, though. I've seen the thread about "Sieve vacation with russian subject" at http://www.dovecot.org/list/dovecot/2009-July/041031.html , but that wasn't quite a solution. I can't figure out how to work around that, could anyone help out please? Mandatory info: FreeBSD 7.2 i386, dovecot 1.2.3, dovecot-sieve-1.2+0.1.11 And here's the script itself: require ["fileinto", "vacation", "variables"]; set "subject" ""; if header :matches "subject" "*" { set "subject" "${1}"; } vacation :days 1 :subject "RE: ${subject}" "[vacation message text]"; P.S. Stephan Bosch, thank you very much for what you've done with sieve.

[Dovecot] Problem Deleting IMAP Folders
by Stuart Gall 11 Sep '09

11 Sep '09

Hello, In my configuration I have mail_location = maildir:/Mail/frank.gr/%n:INDEX=/Mail/frank.gr/ __Indexes/%u I can create new folders in an IMAP session, but when I try to delete I get permission denied. From the LOG Sep 10 13:20:06 IMAP(stuart): Error: unlink_directory(/Mail/frank.gr/ __Indexes/stuart/.TEST) failed: Permission denied ls -ald /Mail/frank.gr/__Indexes/stuart/.TEST drwx------ 2 mail mem 4096 2009-09-10 13:20 /Mail/frank.gr/__Indexes/ stuart/.TEST/ ls -al /Mail/frank.gr/__Indexes/stuart/.TEST total 12 drwx------ 2 mail mem 4096 2009-09-10 13:20 ./ drwx------ 4 mail mem 4096 2009-09-10 13:20 ../ -rw------- 1 mail mem 156 2009-09-10 13:20 dovecot.index.log It looks like dovecot is trying to unlink the INDEX directory without first deleting the index log file.

[Dovecot] dovecot 1.2 and logging start failures
by Michal Hlavinka 11 Sep '09

11 Sep '09

Hi, I've got report about issue when dovecot fails to start and there is no error logged (error goes only to stderr) situation: 1) dovecot is running 2) dovecot is automatically updated to new version (by yum update daemon), after update, dovecot is restarted (it's part of update script) 3) new dovecot fails to start (for whatever reason) result: dovecot not running and no error message has been logged because (at least some) errors were written to stderr only and not syslog another situation (original issue) was when dovecot was configured to listen for ipv4 and ipv6 connections. ipv6 support was disabled. After server reboot, dovecot failed to start, producing dovecot: Fatal: listen(::, 143) failed: Address already in use only to stderr, nothing in logs. Would it be possible to use syslog for error output sooner or there are any cons? Regards, Michal Hlavinka

[Dovecot] New need to delete dovecot-acl-list in dovecot 1.2?
by Adam McDougall 10 Sep '09

10 Sep '09

I just started testing 1.2.3 then 1.2.4 this week, I was too busy earlier in the year to look at 1.2 at all. So far so good except I noticed newly granted permissions via ACL on some newly created public mailboxes were not visible by the client. It seemed to be a version thing because the same files work fine concurrently on a server running 1.1.x. I came across this in the ACLwiki which seems to fix it: List cache dovecot-acl-list file lists all mailboxes that have "l" rights assigned. If you manually add/edit dovecot-acl files, you may need to delete the dovecot-acl-list to get the mailboxes visible. I don't ever recall needing to do this before, and it sounds similar to this which I have had set to 10 for a long time: # cache_secs parameter # specifies how many seconds to wait between stat()ing dovecot-acl file # to see if it changed. All of my dovecot-acl files are symlinks so hopefully it runs stat() on the target, but just in case I tried recreating the symlink afterwards but it didn't help and its over NFS so who knows if the running dovecot 'saw' it. Do I need to debug this behavior further or will I just have to live with remembering to delete the dovecot-acl-list file when I manually change dovecot-acl contents? Thanks.

[Dovecot] Odd/Incorrect Quota Reporting on Dovecot 1.2.4 & FreeBSD4
by Siraj 'Sid' Rakhada 10 Sep '09

10 Sep '09

Hi, Am seeing an odd problem on an old FreeBSD 4.11 box that I'm trying to get courier off, and dovecot on. At the same time, I'm trying to put some fairly simple quota support on, but getting very odd results. I think it might be better described with the log below, but, the gist of it is this: I have set a 1GB quota, and I was getting intermittent reports on the quota usage - sometimes at the correct usage (300MB or so), and then at some crazy amount over the quota usage. I can get it to be consistently incorrect though, as displayed with the below log. The maildirsize is correct, and matches closely to 'du' output, it's simply coming through incorrect on IMAP. It also only seems to happen if the maildirsize is not created before the first 'getquota[root]' command occurs. I think it's something to do with dovecot + FreeBSD (at least, this version)! I've done a quick test on a Debian box, and I don't have the same problem. Anyone else have any ideas what could be going wrong on this FreeBSD box? Is it worth me giving the dovecot -n output at this stage? It happens on different mailboxes too, this is just a sample. Thanks! ----- information & log follow # /usr/local/dovecot/sbin/dovecot --version 1.2.4 # uname -a FreeBSD server1.domain 4.11-RELEASE-p13 FreeBSD 4.11-RELEASE-p13 #5: Wed Oct 12 18:02:46 BST 2005 root@server1.domain:/usr/obj/build/src/sys/FBSD410RELENG i386 # cat maildirsize 1073741824S 304806180 16002 Attempt 1: .

[Dovecot] Password & Authentication schemes to comply with postfixadmin
by bsd 09 Sep '09

09 Sep '09

Hello, I am using the latest version of Dovecot on a FreeBSD box. I am trying to figure out which password scheme to use to comply with my database backend which is administered by "postfix admin". Here is an example of the password that can be generated in the database using the various encryption schemes available in postfix admin: $1$a733fb07$/g1h6opQxemdWUtzD2/kQ. --> md5crypt 25f9e794323b453885f5181f1b624d0b --> md5 acFhkap78XB2I --> system I am not certain I have understood very well how things all feet together… I have tried to modify the various options in dovecot-mysql.conf in order to comply with these settings: I have updated "default_pass_scheme" to "PLAIN-MD5, DIGEST-MD5, and CRYPT" but none of this seems to work. Do I have to modify something in dovecot.conf? For the moment I have these settings: auth default { mechanisms = plain login passdb sql { args = /usr/local/etc/dovecot-mysql.conf } userdb sql { args = /usr/local/etc/dovecot-mysql.conf } socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } The main idea is simply not to have cleatext passwd in the DB. Thanks for your support. ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯ Gregober ---> PGP ID --> 0x1BA3C2FD bsd @at@ todoo.biz ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯ P "Please consider your environmental responsibility before printing this e-mail"

[Dovecot] LDA does not read quota from userdb's extra fields
by Tim Chen 09 Sep '09

09 Sep '09

The version I use is dovecot 1.2.4 My config in dovecot.conf protocol imap { mail_plugins = quota imap_quota mail_log } protocol lda { mail_plugins = quota } userdb passwd-file { args = /etc/dovecot.userdb } quota = maildir quota_rule = *:storage=100MB /etc/dovecot.userdb user1:*:2001:2001::/ms/user1::userdb_quota_rule=*:storage=300M And in postfix/main.cf mailbox_command = /usr/local/libexec/dovecot/deliver I wish to have a global quota 100MB for all the users and using /etc/dovecot.userdb to specify larger quota(300MB) for some vip users. IMAP works normally as expected, using the following command will report correct quota. a login user1 pass1 user1 getquotaroot INBOX However, it seems LDA treat all users the same quota (100MB), and when trying to send mails to those vip users(300MB), it will reject the email and report "552 Requested mailbox exceeds quota. (in reply to RCPT TO command))" My speculation is LDA forget the read 'extra fields' from userdb, would you please help to verify it? Thanks very much for your help. Sincerely, Tim Chen

Hi again! After sometime using my changes on this plugin I found one major problem. When a message have two attachments with same name or one with content-type equal to "message/*", my solr schema design does not work because as attachment unique identifier I used attachment's name what is not correct. Now I am trying to find a way to know the mime part id of the parts used on fts_build_mail. Is that already possible or I need to do that by my own? Thank you in advance, Rui Carneiro

[Dovecot] The usage of dovecot-uidvalidity* files?
by Tim Chen 09 Sep '09

09 Sep '09

After installing a new server with dovecot 1.2.4, I found there is some new dovecot-uidvalidity* files in user's Maildir directory. However, I did not see such files in other servers with dovecot 1.1.2 (around 2008/07). What is function of those files? What will happen if I delete that files? I am curious why need to keep 2 files: dovecot-uidvalidity dovecot-uidvalidity.4aa4fa4c since the content of dovecot-uidvalidity is '4aa4fa4c' why do we need extra files? Thanks Timo for providing the wonderful dovecot software! Hope you don't mind my stupid questions. Sincerely, Tim Chen

[Dovecot] compression script for use with zlib module
by Leonardo Rodrigues 09 Sep '09

09 Sep '09

Hi, I'm wondering if someone already implemented a compression script (and would like to share it) based on the step-by-step provided on wiki page of Zlib module. I can already do some find|xargs gzip .... but couldnt implement it completly as described on the wiki page. I know the suggested step-by-step is very detailed and probably a must simplier will be enough for almost anyone .... anyway, if someone have the full script and would like to share it, i would be glad to get it :) http://wiki.dovecot.org/Plugins/Zlib 1) Find the mails you want to compress in a single maildir. 2) Compress the mails to tmp/ * Update the compressed files' mtimes to be the same as they were in the original files (e.g. touch command) 3) Run maildirlock <path> <timeout>. It writes PID to stdout, save it. * <path> is path to the Maildir's dovecot-uidlist (the control directory, if it's separate) * <timeout> specifies how long to wait for the lock before failing. 4) If maildirlock grabbed the lock successfully (exit code 0) you can continue. 5) For each mail you compressed: 1. Verify that it still exists where you last saw it. 2. If it doesn't exist, delete the compressed file. Its flags may have been changed or it may have been expunged. This happens rarely, so just let the next run handle it. 3. If the file does exist, rename() (mv) the compressed file over the original file. * Dovecot can now read the file, but to avoid compressing it again on the next run, you'll probably want to rename it again to include e.g. a "Z" flag in the file name to mark that it was compressed (e.g. 1223212411.M907959P17184.host,S=3271:2,SZ). Remember that the Maildir specifications require that the flags are sorted by their ASCII value, although Dovecot itself doesn't care about that. 6) Unlock the maildir by sending a TERM signal to the maildirlock process (killing the PID it wrote to stdout). -- 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] Using Dovecot code in a non-LGPL package
by Asheesh Laroia 08 Sep '09

08 Sep '09

Hi Timo (and all!), Venaktesh is a friend of mine working on a patch to the venerable Alpine mail reader so it can read Maildir format mailboxes on disk. Venkatesh wanted to know if he could use some code from Dovecot's lib-storage (safely opening/reading Maildirs, including accounting for NFS and ESTALE) and the UID->message mapping code. This way, Dovecot and Alpine would agree on how to handle UIDs for a given Maildir-format mailbox. Plus Alpine could benefit from the thought you've put into the safety of Maildirs on IMAP (which is *not* trivial!). But there are some possible licensing issues. Alpine (formerly known as PINE) is now licensed under the Apache License 2.0. As far as I can tell, if he wants to contribute a patch back to Alpine upstream, he should use use the Apache License 2.0. But Dovecot is licensed under LGPL 2.1; if he takes Dovecot code, modifies it, and mixes it with Alpine, that would not be allowed by the licenses together (as I understand it). The Apache License 2.0 is a permissive, non-copyleft license like the MIT License, but it adds a patent retaliation clause. See http://www.apache.org/licenses/LICENSE-2.0.html for its text and http://www.gnu.org/philosophy/license-list.html for a short statement of its compatibility with GPLv3; http://en.wikipedia.org/wiki/Apache_License#GPL_compatibility has a little more. License-wise, there are two choices, if you're willing Timo: the modified Dovecot code could be released under GPLv3, which *is* compatible with the Alpine license - it would just mean Alpine+Maildir would be GPLv3 when put together. Or you could grant a special permission to Venkatesh to distribute the modified Dovecot code under the Apache License 2.0. Timo (and others), what do you think? The past of least resistance is to say that a derivative work of Dovecot can be made using GPLv3; the most convenient would be to say that particular portions can be used under the Apache License 2.0. -- Asheesh. -- Why do we have two eyes?

[Dovecot] Unusual IMAP config.
by S. A. Woltering 08 Sep '09

08 Sep '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, perhaps a silly question, perhaps an unusual one, I don't know. I'm trying to suss out how to set up Dovecot in such a way as to have two separate IMAP services running on the same system. To explain. We have an "internally-facing" IMAP and an "externally-facing" one. It's policy that anyone connecting to IMAP from outside uses a stronger authentication method than the default internal one. The current system uses the standard imap/imaps ports for internal auth, but a different port-pair for external access. (actually it's a bit more complex than that, but that's all I really need to go into for this exercise!) So, for example, I'd like to kick off a test rig that uses IMAP on port 143 using a standard password (file or NIS) auth and to set up another on port, say 144 using PAM. Can this be done within one single dovecot.conf, or should I be running two separate daemons?

[Dovecot] avoiding DoS
by David Halik 07 Sep '09

07 Sep '09

Hi, I was just looking for some advice on avoiding getting DoS'd from brute force log in attempts. We came in this morning to find that one of our Solaris 9 dovecot severs had wedged overnight due to a brute force connection attempt to pop3 from Brasil. In the span of about 15 seconds we received 342 connection auth attempts from the same IP: Sep 3 00:10:51 xxxxx dovecot: [ID 583609 mail.info] auth(default): new auth connection: pid=16862 Sep 3 00:10:51 xxxxx dovecot: [ID 583609 mail.info] auth(default): new auth connection: pid=16863 Sep 3 00:10:51 xxxxx dovecot: [ID 583609 mail.info] pop3-login: Login failed: Plaintext authentication disabled: rip=189.99.178.15, lip=xxxxx Sep 3 00:10:51 xxxxx dovecot: [ID 583609 mail.info] pop3-login: Aborted login (tried to use disabled plaintext auth): rip=189.99.178.15, lip=xxxxx Dovecot finally wedged silently and without complaint, becoming completely unresponsive. I had to kill -9 it this morning in order to restart the service. Once possibility I considered was that the dovecot user process limit was reached, but this is set to 1024, and I didn't see any errors or warnings anywhere in the logs. login_max_processes_count = 256 max_mail_processes = 1024 With the above I would think it would have been able to handle it gracefully, but apparently it did not. ulimit -n 2048 is also set on dovecot startup for the fd limit. Any suggestions on what I could tweak to prevent this from happening in the future? dovecot -n output: Note I upgraded to 1.2.4 this morning while it was already down. We were running either 1.2.0 or 1.2.1 last night, sorry didn't think to check first. ;) bash-2.05# ulimit -n 2048; dovecot -n # 1.2.4: /usr/local/etc/dovecot.conf # OS: SunOS 5.9 sun4u protocols: imap imaps pop3 pop3s ssl_cert_file: /usr/local/ssl/certs/nbcs.key+crt.pem ssl_key_file: /usr/local/ssl/certs/nbcs.key+crt.pem login_dir: /usr/local/var/run/dovecot/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_max_processes_count: 256 max_mail_processes: 1024 mail_location: maildir:~/Maildir:INDEX=/toolbox/nqu%h/dovecot:CONTROL=/toolbox/nqu%h/dovecot mmap_disable: yes mail_nfs_storage: yes mail_nfs_index: 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 fts fts_squat mail_plugins(imap): quota imap_quota fts fts_squat 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 pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): UID%u-%v namespace: type: private separator: . prefix: INBOX. inbox: yes list: yes subscriptions: yes lda: postmaster_address: postmaster(a)jla.rutgers.edu auth default: verbose: yes debug: yes passdb: driver: pam args: * userdb: driver: passwd plugin: quota: fs fts: squat fts_squat: partial=4 full=4 -- ================================ David Halik System Administrator OIT-CSS Rutgers University dhalik(a)jla.rutgers.edu ================================

[Dovecot] assertion failed while using sieve
by Maciej Uhlig 07 Sep '09

07 Sep '09

Hi, there is a line in TODO: "- sieve-cmu.c crash: i_assert(buf->used - 1 == part->body_size.physical_size); ". Yes, we've really seen this crash. Therefore we upgraded to dovecot-1.2.3 with dovecot-1.2-sieve-0.1.11 in order to use sieve plugin (i.e. not cmu-sieve). We use Solaris 10 on Sun servers, we don't use NFS. However, unfortunately, dovecot with sieve crashes too. Here is dovecot log excerpt: 2009-09-01T02:40:57+02:00 prac/prac dovecot: [ID 583609 mail.crit] deliver(id@domain): Panic: file ext-body-common.c: line 149: assertion failed: (buf->used - 1 == part->body_size.physical_size) 2009-09-01T02:40:57+02:00 prac/prac dovecot: [ID 583609 mail.crit] deliver(id@domain): Panic: file ext-body-common.c: line 149: assertion failed: (buf->used - 1 == part->body_size.physical_size) 2009-09-01T02:40:57+02:00 prac/prac dovecot: [ID 583609 mail.error] deliver(id@domain): Raw backtrace: 0xbd27c -> 0xfead33b0 -> 0xfead358c -> 0xfead396c -> 0xfead4a78 -> 0xfeaa19dc -> 0xfeaa1abc -> 0xfeaa1c38 -> 0xfeabf22c -> 0xfeabf520 -> 0xfea90b20 -> 0xfea91048 -> 0xfea91404 -> 0x26e58 -> 0x23778 Now, some background. We use a sieve script with >>require "body"<<. This script compiles correctly and more, it works correctly while named as >>id(a)domain.sieve<< or >>id(a)domain.svbin". Nevertheless while the very same script is defined in plugin section of dovecot conf as "sieve = script" or "sieve_before = script" or "sieve_after = script" then dovecot crashes. I consider it as an important hint for problem resolution. Moreover, not every mail is affected, but we didn't investigate which mails are correctly saved to inbox and which crash. The effect is, we're not able to implement global sieve policies which is bad because we really need them :-). We'd than be happy to test fixes, if any. Best regards, MU

[Dovecot] local delivery agent
by legionaer85 07 Sep '09

Hey, i've got a problem with my lda and exim, probably i assume that it's dovecot. I think that, because i get an error in exim: T=dovecot_delivery: Child process of dovecot_delivery transport returned 67 (could mean user nonexistent) from command: /usr/lib/dovecot/deliver in exim i use /usr/lib/dovecot/deliver -d <name>@<domain>.<tld> -f <name>@<domain>.<tld> So, i tried to focus the error and thought there is not the right argument for delivery. But i couldn't get any hints about the arguments for the deliver agent. Exim gives me a complete string which is 'name(a)domain.ltd' Now my question. How parses the deliver agent this string? Splits it into variables? If yes... to which ones? name and domain? Thanks a lot for any answers. =>dovecot --version 1.0.rc15 ------ =>dovecot -n # /etc/dovecot/dovecot.conf log_path: /var/log/dovecot/main.log info_log_path: /var/log/dovecot/info.log log_timestamp: %Y-%m-%d %H:%M:%S ssl_cert_file: /etc/ssl/certs/ssl_cert.crt ssl_key_file: /etc/ssl/certs/ssl.key login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_user: vmail login_greeting: <servername> Mailserver ready. verbose_proctitle: yes first_valid_uid: 8 last_valid_uid: 8 mail_privileged_group: mail mail_location: dbox:/var/spool/mail/%d/%n mail_debug: yes auth default: user: mail passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: prefetch socket: type: listen client: path: /var/run/dovecot/auth-client mode: 384 user: mail group: mail master: path: /var/run/dovecot/auth-master mode: 384 user: mail group: mail --------- =>grep -v '^ *$#.*$\?$' /etc/dovecot/dovecot-sql.conf driver = mysql connect = host=<host> dbname=<dbname> user=<user> password=<pass> default_pass_scheme = PLAIN password_query = SELECT password, '/var/mail/%d/%n' AS userdb_home, 'mail' AS userdb_uid, 'mail' AS userdb_gid FROM user WHERE username = '%n' AND domain = '%d' AND IMAP_allowed = 'YES' user_query = SELECT username, uid, gid FROM user WHERE username = '%n' AND domain = '%d' --------- in the db i have the user table columns: username, domain, password

[Dovecot] setting up both system password users AND virtual users
by Markus Bonet 07 Sep '09

07 Sep '09

Hi, I want to pick up this discussion. I am trying to achieve the same, but I am using Maildir instead. Here's the (relevent part of the) config file as configured by the recent suggestion: # We're using Maildir format mail_location = maildir:~/Maildir # Authentication configuration: auth_verbose = yes auth default { mechanisms = plain userdb passwd { } userdb static { args = uid=vmail gid=vmail home=/daten/mailusers/%u } passdb passwd-file { args = /etc/dovecot/passwd } } But when I try to login in to a system's user mailbox, it'll be rejected as unknown in my Dovecot's passwd file. I am converting from courier-imap, so I am kind of new to Dovecot. Markus

[Dovecot] IMAP activity after disconnect
by Charles Sprickman 07 Sep '09

07 Sep '09

Howdy, I'm running Dovecot 1.1.16 on a staging server to do some testing before building a new server and moving a bunch of qmail/vpopmail/courier accounts over. I wanted to test the migration of courier accounts to dovecot with a few clients, so I copied over a few large accounts. All went well with a small account (100+ messages) when accessing the account via POP - no re-downloads after adjusting the uidl format. IMAP looks good as well after running the conversion script and setting the namespace properly. However, one thing I copied over without paying much attention was a non-quota'd spam box that has literally not been checked in at least a year: [root@nac /var/vmail/xxx.com/spork/Maildir/.Spam]# ls new/| wc -l 70501 Mail.app valiantly tried to sync this, but when I realized just how huge this was, I took the account offline and quit the app. However it seems like Dovecot is still busy doing something in that mailbox: lsof: no pwd entry for UID 5000 imap 27515 5000 7uW VREG 0,95 3372 2968764 /jails/nac.xxx.com/var/vmail/xxx.com/spork/Maildir/.Spam/dovecot.index.log lsof: no pwd entry for UID 5000 imap 27515 5000 8u VREG 0,95 488 3007349 /jails/nac.xxx.com/var/vmail/xxx.com/spork/Maildir/.Spam/dovecot.index lsof: no pwd entry for UID 5000 imap 27515 5000 9u VREG 0,95 25195 27064933 /jails/nac.xxx.com/var/vmail/xxx.com/spork/Maildir/.Spam/dovecot-uidlist lsof: no pwd entry for UID 5000 imap 27515 5000 10r VDIR 0,95 15171072 2968758 /jails/nac.xxx.com/var/vmail/xxx.com/spork/Maildir/.Spam/new My guess is it's trying to build an index. This process is chewing up 100% of whatever cpu it lands on. Is this expected behavior (not the huge cpu usage, but the imap server continuing to work on the box after the client has logged out)? Are there any config settings I've missed to sort of put a cap on how much cpu/time dovecot will spend on a task like this? So far this has been running for about 20 minutes. I'm going to kill it and manually delete the spam since I'm not familiar enough with gdb to dig in and see just what it's doing (although my guess is indexing). On the upside, I have some serious spam magnet addresses in this test domain, so now I've got a great platform to test my amavis/postfix/policy skills. :) Thanks, Charles ___ Charles Sprickman NetEng/SysAdmin Bway.net - New York's Best Internet - www.bway.net spork(a)bway.net - 212.655.9344

[Dovecot] mbox to maildir migration question and problems, dovecot-1.0.7-7.el5
by Eric Sammons 07 Sep '09

07 Sep '09

Hi, I am trying to assist a customer with a mbox to maildir migration. I have them using the latest and greatest mb2md.pl; the one that support -K, -U|-u. They have seen overwhelming success with this; however, a recent mbox introduced a new scenario and the result was that all messages were replayed in the client UI. The mbox in question had _no_ X-UID tags. To work-a-round the issue the customer performed the following steps. [snip] We found that the fix was to clear /var/indexes/$USER for the account and log in and log back out. After doing this X-UID's were populated for each respective message. [/snip] The customer also noted that after the migration all messages went to ~/MailDir/new. I would appreciate any thoughts on why this scenario played out the way it did? Is it expected that these messages should reside in ~/MailDir/new? [config] protocol pop3 { pop3_uidl_format = %08Xv%08Xu pop3_reuse_xuidl = yes } [/config] Thank you! -- Eric L. Sammons, RHCE

[Dovecot] Problem with ldap error logging
by Stefano Fedrigo 07 Sep '09

07 Sep '09

I configured dovecot to authenticate through ldap. When for some reason the ldap server is not working dovecot writes this message to the system log: dovecot: auth(default): accept(type 1) failed: Too many open files "Too many open files" is caused by an openldap bug. The serious problem is that dovecot repeats that message a huge number of times, something like 20000 times per second, until the ldap daemon starts working or, more likely, no more disk space remains. -- // Stefano Fedrigo - Develer S.r.l. \X/ http://www.develer.com

[Dovecot] mail_uid and mail_gid are not set in environment (for expire-tool and so)
by Baptiste Malguy 07 Sep '09

07 Sep '09

Hello, I've just subscribed to the list, as a recent user of Dovecot (1.2.4 by now). I eventually missed a point, so I tried to find other doc or comments about my issue, but failed to. If the following has already been discussed, please simply reply with a URL to the corresponding thread or doc ;-) Now that I have covered my ass, here is the problem I meet. In dovecot.conf, I have the following: mail_uid = vmail mail_guid = vmail which is confirmed with 'dovecot -n' I have a script my-expire-tool-test containing: #!/bin/sh set which basically only display environment variables. When I run : /usr/sbin/dovecot --exec-mail ext my-expire-tool-test I do not see any variable MAIL_UID nor MAIL_GID. As a consquence, when I run /usr/sbin/dovecot --exec-mail ext my-expire-tool with my-expire-tool containing: #!/bin/sh # This script is a workaround for Dovecot 1.2 having issue to load modules when running expire-tool. # More information: http://wiki.dovecot.org/Plugins/Expire, search Dovecot v1.2 MAIL_PLUGINS=${MAIL_PLUGINS//antispam/} MAIL_PLUGINS=${MAIL_PLUGINS//imap_acl/} MAIL_PLUGINS=${MAIL_PLUGINS//imap_quota/} MAIL_PLUGINS=${MAIL_PLUGINS//mail_log/} exec /usr/lib/dovecot/expire-tool "$@" It politely tells me: Error: userdb(user@domain) didn't return uid and mail_uid not set Actually, this is this message error that lead me to check the environment variables. Then I also checked the source code, and run: grep -r env_put . | grep -i mail_ No trace of mail_uid nor mail_gid. Did I find a bug or did I miss a point ?

[Dovecot] odd dovecot / spampal interaction
by gyre 07 Sep '09

07 Sep '09

[Apologies if you've seen this message twice. I originally sent it from another e-mail account but it never seemed to appear on the list for me.] Apologies if this has been mentioned before. I've searched quite a few of the archives, but haven't found an answer. I've just installed dovecot 1.1.6 on my qnap server, and have found an odd interaction with spampal that I've not seen before using other imap servers. Let me attempt to explain. On the mail server machine, I use XMail to pull in new messages from my external pop3 mail account. These messages are then visable to dovecot's imap server. On my mail client machine, I have a spampal proxy between outlook express and the imap server. So, when I wish to read mail, outlook express connects to the spampal proxy and spampal then connects to the dovecot imap server. That all works fine until a message that spampal thinks is spam arrives. spampal instructs the dovecot imap server to move the message from Inbox to the Spam folder and then expunge Inbox. However, erroneously, a random message in my Inbox now seems to lose its seen flag. So if I have 5 new spam messages arrive, all 5 get moved from Inbox to Spam, but correspondingly 5 messages in the middle of my Inbox are now apparently not seen, so outlook express says there are 5 unseen messages, and lets me move down to them. It's almost as if the flags for the Spam folder are being applied to the Inbox folder instead. I've used wireshark to capture an example session of this happening when 2 spam messages arrive, in the hope that somebody wiser than I can work out what is going wrong, and where. Any help gratefully received. Thanks. -- gyre --

[Dovecot] Problems with sieve
by Stefan Onken 07 Sep '09

Hello, I am trying to setup an Email Server with Exim, dovecot and sieve support. I am not sure about the settings for Sieve, right now its's not working properly: user: test3(a)gewaltphantasien.de maildir: /var/mails/gewaltphantasien.de/test3 I have the .dovecot.sieve file in the root dir of the users emails: root@ubuntu:/var/mails/gewaltphantasien.de/test3# cat /var/mails/gewaltphantasien.de/test3/.dovecot.sieve require "vacation"; vacation # Reply at most once a day to a same sender :days 1 :subject "Out of office reply" # List of additional recipient addresses which are included in the auto replying. # If a mail's recipient is not the envelope recipient and it's not on this list, # no vacation reply is sent for it. :addresses ["test3(a)gewaltphantasien.de", "john.doe(a)company.dom"] "I'm out of office, please contact Joan Doe instead.

[Dovecot] offlineimap with dovecot: file-time is one hour in the future
by Dieter Faulbaum 04 Sep '09

04 Sep '09

I use offlineimap to sync my remote IMAP-server with my local IMAP-server (maildir format). But I don't understand this behavior: every new mail in the INBOX has a file-date which is one hour in the future. Is this 'normal'? Is this a problem of offlineimap? I tried this debugging (for dovecot): mail_executable = /usr/lib/dovecot/rawlog /usr/lib/dovecot/imap and this (for offlineimap): offlineimap -d imap,maildir,thread -l ~/offlineimap.log But I can't find any helpful information in these files, which shows me what went wrong. Has anyone a better technique or a hint how to find out what caused this (little) problem? -- Dieter Faulbaum

[Dovecot] v2.0 configuration parsing
by Timo Sirainen 04 Sep '09

04 Sep '09

I'm trying to figure out how exactly v2.0 should be parsing configuration files. The most annoying part is if it should always just "use whatever comes first in config" or try some kind of a "use most specific rule". The "most specific" kind of makes more sense initially, but then you start wondering how to handle e.g.: 1) User logs in to imap from 192.168.0.1. What is foo's value? protocol imap { remote_ip 192.168.0.0/16 { foo = foo } } remote_ip 192.168.0.0/24 { foo = bar } 2) User logs in from 192.168.0.1 to 10.1.2.3. What is foo's value? local_ip 192.168.0.1 { remote_ip 10.1.2.0/24 { foo = foo } } remote_ip 10.1.2.3 { local_ip 192.168.0.0/24 { foo = bar } } Any thoughts?

[Dovecot] quota-dirsize and mailbox rules
by Thanos Chatziathanassiou 04 Sep '09

04 Sep '09

I noticed that the dirsize backend for quota didn't support any rules and figured it should be easy enough to add ``ignore'' at least. Using mbox storage and only tested with that, but it seems to work as expected for the time being. I'm attaching a relatively small patch for quota-dirsize.c against dovecot-1.1.18 just in case anyone's interested. Best Regards, Thanos Chatziathanassiou

[Dovecot] IMAP timeout problem
by Vasantha Narayan 04 Sep '09

04 Sep '09

Hello, We are running dovecot 1.1.2 on a Solaris 10 box. We have been running the same configuration for about a year without a problem. We have a different cert for POP and IMAP. Recently we made two changes. The cert for IMAP expired and we had to install a new one. We applied some patches to the SAN disks that hosts the mail partition. These changes were made over a weekend and the system was rebooted. There were no errors in the logs and everything worked fine until the following Monday morning when IMAP connections increased. When IMAP ports started getting hammered in the morning, IMAP clients started getting "IMAP time out" errors. When this error occurs, IMAP freezes and IMAP clients such as, Thunderbird and Squirrelmail are not able to connect to the IMAP server (both IMAP and IMAPS). We cannot get a telnet connection to the IMAP port or a openssl connection to the IMAPS port. Kill -HUP of the dovecot server solves the problem. But again, when the usage increases, the problem surfaces again. There is no problem with POP or POPS. It continues to function normally while IMAP times out and freezes two or three times a day. Any clue where the problem might be? The debug log does not have any useful pointers. Thanks. Vasantha

[Dovecot] External auth database process
by Aaron Roberts 04 Sep '09

04 Sep '09

Hi, Is it possible to call a completely external process to authenticate users in dovecot? I am trying to setup a transparent pop3 proxy that will lookup users from a couple of different pop3 servers, authenticate to 1 of them, take a copy of the password and a timestamp and client IP upon success, then proxy to the appropriate end server. I was hoping I would be able to do something along the lines of: dovecot.conf: passdb external args = /usr/scripts/dovecot_auth.pl %u %w The perl script would then carry out the various tasks and return the host and destuser for proxying. Thanks in advance, Aaron

[Dovecot] lmtp server
by fernando＠dfcom.com.br 03 Sep '09

03 Sep '09

I believe that dovecot lmtp server will be released with 2.0 version. I working at a project that requires an lmtp server to have scalability. How about the stability of the actual version (alpha, beta ?). Is it mature to be used at production environment ? Another question, my 'ideal' setup would be to receive a message by lmtp and delivers it to an external command (like maildrop). Would it be possible. ? Best Regards, Fernando

[Dovecot] Question about sieve script execution
by Mel Flynn 03 Sep '09

03 Sep '09

Hi, after reading the wiki about sieve_before/sieve_after and sieve_global_path, it's still unclear to me if: sieve_before scripts are executed if no user script exists, but a global script is defined. The reason I ask, is because I'd like to use the same script, so that I don't have to maintain two scripts to apply "company policy" or "global features". It seems implicit from this sentence, but I've been taught not to assume implicitness by various pieces of software ;) "This is not possible using the sieve_global_path setting, because that is only used when the user's private script does not exist." -- Mel

[Dovecot] POP3 and AVG
by Rick Romero 02 Sep '09

02 Sep '09

Is anyone running v 1.2.3 and have clients with AVG email scanning? I upgraded a server a few weeks ago (which ran Dovecot and the Maildir mail store), and all of a sudden clients with AVG were unable to use POP. Essentially, AVG freezes. The server upgrade was from FreeBSD 7 to OpenSolaris 2009.06, and I did upgrade the Dovecot version from 1.1.17 to 1.2.3, but kept the same config. When I point those users to a port running qmail-popup on another machine (NFS mounting the new server), they work fine. I'm sure I reverted to 1.1.17 during the initial hectic days, with no change. Of course, I'm also sure I had a few of the users test the alternate qmail-popup server, maybe they did it wrong. :( Any thoughts?

Re: [Dovecot] Question about ACL/flags

So for example: To refresh, I want a shared account, but my system was Dovecot 1.1 with all mbox mailboxes.

[Dovecot] Global ACL configuration problems: mailboxes not visible, set ACLs not honoured
by Andreas Ntaflos 01 Sep '09

01 Sep '09

Hi list, I am having trouble getting global ACLs to work correctly. This is, I assume, an issue separate from the one I reported a few days ago [1], where the imap process crashes when creating subfolders of folders with an ACL set. As you can see from my 'dovecot -n' output below I have three namespaces; two private ("Backup" and the default, empty one) and one public ("Public"). I also use the autocreate plugin to create a few standard folders. Those folders, along with some others, should have some special permissions and restrictions in place. I.e. messages must not be deletable, the mailbox itself may not be deleted, etc. I want to use global ACLs so that I don't have to put a dovecot-acl file in every folder that I want to have an ACL set. Thus, according to the wiki, if have set acl:vfile:/etc/dovecot/acls I can create files named "Sent", "Trash", "Drafts", "INBOX.Spam" and "Backup.sent", "Backup.received", "Public.Spam", "Public.Ham" in the directory /etc/dovecot/acls. These files contain the ACL, such as "owner lrp", "owner lrwsipk" and "authenticated lrwstipk". Any and all "dovecot-acl-list" files have been deleted before testing and reproducing that problem again just now. Is there anything more to it? I ask, because I can't seem to get it to work correctly using this approach with global ACLs. Problems include: - Can't get the mailboxes "Spam" and "Ham" under the "Public" namespace to show up in the mail client (Thunderbird, KMail, Horde/IMP) at all. These have the ACL "authenticated lrwstipk" set so the should be visible to authenticated clients, shouldn't they? All I see is the namespace with no mailboxes beneath it. - Deleting messages from the "Backup.sent" or "Backup.received" mailboxes is possible from Thunderbird, KMail and Horde/IMP, despite having the ACL "owner rlp" set, which, if I understand correctly, should only allow users to lookup, read and post to the mailing list via LDA/Sieve. What am I doing wrong? It seems to me that the global ACL files for namespaces other than the empty one are not at all considered? Do I have to use another notation for the ACL file names? Any help is much appreciated. Thanks in advance! Configuration information follows. Contents of /etc/dovecot/acl ============================ Backup.received owner rlp Backup.sent owner rlp Drafts owner lrwstipk INBOX.Spam owner lrwstipk Public.Ham authenticated lrwstipk Public.Spam authenticated lrwstipk Sent owner lrwstipk Trash owner lrwstipk 'dovecot -n' ============ # 1.2.4: /usr/local/etc/dovecot.conf # OS: Linux 2.6.26-2-686 i686 Debian 5.0.2 log_timestamp: %Y-%m-%d %H:%M:%S protocols: managesieve imap imaps pop3 pop3s login_dir: /usr/local/var/run/dovecot/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_executable(managesieve): /usr/local/libexec/dovecot/managesieve-login mail_access_groups: mail mail_privileged_group: mail mail_location: maildir:~/Maildir mail_drop_priv_before_exec: 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_executable(managesieve): /usr/local/libexec/dovecot/managesieve mail_plugins(default): autocreate acl mail_plugins(imap): autocreate acl mail_plugins(pop3): mail_plugins(managesieve): 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 mail_plugin_dir(managesieve): /usr/local/lib/dovecot/managesieve namespace: type: public separator: . prefix: Public. location: maildir:/var/mail/public:CONTROL=~/Maildir/control/public:INDEX=~/Maildir/index/public list: yes namespace: type: private separator: . prefix: Backup. location: maildir:~/Maildir-backup hidden: yes list: no namespace: type: private separator: . inbox: yes list: yes subscriptions: yes lda: log_path: info_log_path: auth_socket_path: /var/run/dovecot/auth-master postmaster_address: postmaster(a)mailtest0.rise-s.com mail_plugins: sieve acl auth default: mechanisms: plain login passdb: driver: pam passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: passwd userdb: driver: static args: uid=vmail gid=vmail home=/var/vmail/%Ld/%Ln allow_all_users=yes socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail plugin: sieve: ~/.dovecot.sieve sieve_dir: ~/sieve sieve_global_path: /etc/dovecot/sieve/default.sieve sieve_global_dir: /etc/dovecot/sieve/global/ sieve_before: /etc/dovecot/sieve/before/ autocreate: Trash autocreate2: Drafts autocreate3: Sent autocreate4: INBOX.Spam autosubscribe: Trash autosubscribe2: Drafts autosubscribe3: Sent autosubscribe4: INBOX.Spam acl: vfile:/etc/dovecot/acl [1] http://dovecot.org/list/dovecot/2009-August/042467.html -- Andreas Ntaflos Vienna, Austria GPG Fingerprint: 6234 2E8E 5C81 C6CB E5EC 7E65 397C E2A8 090C A9B4

[Dovecot] v2.0 configuration paths
by Timo Sirainen 01 Sep '09

01 Sep '09

In Dovecot v2.0 I'm splitting dovecot-example.conf to multiple files. It's probably annoying to have tons of dovecot-*-example.conf files, so what do you think about: 1. Change default sysconfdir from $prefix/etc to $prefix/etc/dovecot (that's what most distros do anyway) 2. Install *.conf files to $sysconfdir/example/ without the "-example" part in any of the config files. So new installations would then start with "mv example/* ."

[Dovecot] Active IMAP sessions per server?
by Brent Bloxam 31 Aug '09

31 Aug '09

Hi, I'm curious about some of the larger dovecot installs out there and what your current active user load looks like per server. Realistically, how many active IMAP sessions are some of you maintaining? At what point did you find the load became unmanageable? I know there's a lot of different factors involved in this, but I'm just looking to get a rough idea of what I can expect to be able to handle with dovecot. Any help is appreciated Regards, Brent

[Dovecot] Quotas ignored on INBOX only
by Random Monkey 31 Aug '09

31 Aug '09

I have set up postifx and dovecot (1.1) with virtual users and delivery via LDA. I am very pleased with the results so far but have this problem with quotas. Setting a global quota using plugin { } I initially used maildir to set quotas, but they seem to apply to all folders apart from INBOX. For debugging I switched maildir to dict using mysql. The table populates as it should with sizes and message count for all messages created in trash/drafts/sent folders - but messages in the INBOX do not increment size or message count in the table. I have tried with quota rules for both messages and storage. I have also tried specifying INBOX instead of * Any suggestions on how to fix please?

[Dovecot] Quick and dirty server optimized for IMAP upload speed?
by Adam McDougall 31 Aug '09

31 Aug '09

Early next week I need to upload over 100,000 emails to an IMAP server as quickly as possible from an Outlook client. I am looking for any methods I can use to (temporarily?) speed up the rate at which dovecot can accept and store IMAP uploads, whether it be storing on local disk, ram disk, etc. I can setup a temporary server on a laptop for example and once the upload has finished I can use standard file copying methods to transfer the mail to stable, permanent storage. I haven't been able to see over about 7 msgs/sec upload speed from a local folder in any mail client to dovecot (only NFS or ZFS backend tested so far with Maildir). Is there something horribly wrong with the speed I am seeing or are there just tricks I can try? Any tips? I'll be working on it all weekend until I find something satisfactory. It seems like I can upload mails to an Exchange server quicker. I'll setup just about anything that my experience allows me to, I can be very resourceful with adhoc hardware and software. Alternatively I'll take a fast way of converting Exchange email to a tree of local mbox files which I can then run mb2md on. I tried using Thunderbird to Import the mails from Outlook and while it was fast, it messed up the formatting of some of the mails so I don't think I can use that. I tried readpst briefly from libpst but it took a long time to run, took alot of cpu, and was spewing lots of errors so I canceled it. Thanks for any input!

[Dovecot] Postfix : lda problem
by denis 30 Aug '09

30 Aug '09

Hi, I come back with my problem: On debian lenny, using dovecot 1.1.13-2~bpo50+1 I try to configure my setup (with Postfix virtual domains) to use dovecot as lda but nothing happens, as if postfix not delegate to dovecot I am using the contreol panel alternc (http://www.alternc.org) All the maildir are in the format /var/alternc/mail/i/info_domainepublic.net for info(a)domainepublic.net The "virtual_mailbox_maps" will retrieve the correct maildir to deliver the message. For Alternc, an address is considered as an alias of the primary domain name. Thus info(a)domainepublic.net is assimilated to info_domainepublic.net(a)altern.domainepublic.net Here is a sequence of arrival of mail, the result of postconf -n, dovecot -n and the master.cf from postfix I looked in the documentation and google, but I do not understand the problem.

[Dovecot] Dovecot 1.0.14 + osx 10.6 and authentication PAM
by Maarten Koster 30 Aug '09

30 Aug '09

Howdy, Today I installed the new version of Apple OSX 10.6. Besides that it deleted the dovecot user, things went quite smooth. As far as I can tell it is running as it used to. However, I can't login to my account. It used to work fine with PAM taking the username and password from my osx installation. Now it doesn't allow me to login anymore. I have read on a website that apple changed from Linux-Pam to Open-Pam. If this is true, how would I need to change the PAM entry file? Right now it is as follows: /etc/pam.d/dovecot: # dovecot: auth account password session auth required pam_nologin.so auth sufficient pam_securityserver.so auth sufficient pam_unix.so auth required pam_deny.so account required pam_permit.so password required pam_deny.so session required pam_uwtmp.so Here is a list with all dovecot processes Maarten-2:sbin maarten$ ps auxw|grep "dovecot\|imap\|pop3" maarten 249 1,1 0,0 2435032 528 s000 S+ 3:21pm 0:00.00 grep dovecot\|imap\|pop3 dovecot 218 0,0 0,0 602248 660 ??

[Dovecot] Quota question.
by Tom Diehl 29 Aug '09

29 Aug '09

Hi, I am trying to get quota working properly on dovecot 1.2.3 with postfix admin, amavisd-new, mysql, and postfix. So far I can see the db getting updated when messages are added and deleted from the mailbox. The problem I am having is that I have imported a bunch of messages from the old mail server that was running uw-imap and mbox to the doevcot machine using maildir++. As a result the quotas used only reflects what has been added and deleted since the import was done. What is the proper way to get the quota in the database to reflect what is actually in the users mailbox? Google and the wiki have not been helpful to me in figuring this out. I do not really think this is a config problem but in case it is below is the output of dovecot-n: (vfoggy pts7) # dovecot -n # 1.2.3: /etc/dovecot.conf # OS: Linux 2.6.18-128.4.1.el5xen x86_64 CentOS release 5.3 (Final) protocols: imap imaps pop3 pop3sa managesieve listen: * login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_executable(managesieve): /usr/libexec/dovecot/managesieve-login first_valid_uid: 512 last_valid_uid: 512 first_valid_gid: 512 last_valid_gid: 512 mail_location: maildir:~/ mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_executable(managesieve): /usr/libexec/dovecot/managesieve mail_plugins(default): quota mail_plugins(imap): quota mail_plugins(pop3): quota mail_plugins(managesieve): mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 mail_plugin_dir(managesieve): /usr/lib64/dovecot/managesieve imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail imap_client_workarounds(pop3): imap_client_workarounds(managesieve): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh pop3_client_workarounds(managesieve): lda: postmaster_address: postmaster(a)tntechs.com mail_plugins: sieve quota auth default: mechanisms: plain login user: nobody worker_max_count: 50 passdb: driver: sql args: /etc/dovecot/sql.conf userdb: driver: static args: uid=512 gid=512 home=/var/spool/vmail/domains/%d/%n userdb: driver: sql args: /etc/dovecot/sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: vmail master: path: /var/run/dovecot/auth-master mode: 432 user: vmail group: vmail plugin: quota: dict:user::proxy::quotadict sieve: ~/.dovecot.sieve sieve_storage: ~/sieve acl: vfile:/etc/dovecot/acls trash: /etc/dovecot/trash.conf dict: quotadict: mysql:/etc/dovecot/dovecot-dict-quota.conf (vfoggy pts7) # In addition below is what I have in dovecot-dict-quota.conf: 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 } -- Regards, Tom Diehl tdiehl(a)rogueind.com Spamtrap address mtd123(a)rogueind.com

[Dovecot] GSSAPI Authentication Broke with Dovecot 1.1.16 -> 1.2.4 Upgrade
by John Marshall 29 Aug '09

29 Aug '09

This morning I upgraded a dovecot installation from 1.1.16 to 1.2.4 on a FreeBSD 7.2 server, and then spent 3 hours trying to figure out why GSSAPI authentication had broken. It turned out to be a recent change in Dovecot's mech-gssapi.c to do with checking for NULs in usernames: everything worked fine when I disabled that test. <http://hg.dovecot.org/dovecot-1.2/rev/5d53b1d66d1b> This is what I was seeing in the log file with auth_debug enabled: ------------------------ auth(default): client in: AUTH 1 GSSAPI service=imap secured lip=192.0.2.36 rip=192.0.2.168 lport=143 rport=51168 auth(default): gssapi(?,192.0.2.168): Obtaining credentials for imap(a)mail1.example.com auth(default): client out: CONT 1 auth(default): client in: CONT<hidden> auth(default): gssapi(john(a)EXAMPLE.COM,192.0.2.168): security context state completed. auth(default): client out: CONT 1 YGwGCSqGSIb3EgECAgIAb10wW6ADAgEFoQMCAQ+iTzBNoAMCARCiRgREIuGJR3fqiMdvWjEg6utI7bt3fZuI8Ulk4LoFu59aMgnX+Kivdohxin2A71UCEC7oG0sVYe7vrTjg2N9s27D1BLRuJbQ= auth(default): client in: CONT<hidden> auth(default): gssapi(john(a)EXAMPLE.COM,192.0.2.168): Negotiated security layer auth(default): client out: CONT 1 YD8GCSqGSIb3EgECAgIBBAD/////MINNkeu5LVS8fiZNSnb8j8iKBuHArr/sHec++VYV+9SSc+RkAf///wQEBAQ= auth(default): client in: CONT<hidden> auth(default): gssapi(john(a)EXAMPLE.COM,192.0.2.168): authz_name has NULs auth(default): client out: FAIL 1 user=john(a)EXAMPLE.COM imap-login: Disconnected (auth failed, 1 attempts): user=<john(a)EXAMPLE.COM>, method=GSSAPI, rip=192.0.2.168, lip=192.0.2.36, TLS: Disconnected ------------------------ I commented out the 'return -1;' at the end of the if(data_has_nuls) block (to preserve the log message but fall through), rebuilt, and everything works again. ------------------------ auth(default): gssapi(john(a)EXAMPLE.COM,192.0.2.168): authz_name has NULs auth(default): client out: OK 1 user=john(a)EXAMPLE.COM ------------------------ I tried building dovecot 1.2.4 with Heimdal 0.6.3, 1.0.1 and 1.2.1 and all gave the same result.

[Dovecot] ACL in public folders
by Keith Edmunds 28 Aug '09

28 Aug '09

# dovecot --version 1.2.1 I'm trying to configure ACLs for public folders. I have: -------------------------------------------------------------------------------- namespace public { separator = / prefix = shared2/ location = maildir:/home/pubfolders2:INDEX=~/Maildir/public2 subscriptions = no list = children } protocol imap { mail_plugins = acl } plugin { acl = vfile } -------------------------------------------------------------------------------- I have /home/pubfolders2/dovecot-acl containing: user=xyz lrwstiekxa I've also hardlinked the file to /home/pubfolders2/.info (one of the public folders: that dir contains cur,tmp,new). Since enabling ACLs in dovecot.conf, none of the users see the 'shared2' namespace. I've clearly misunderstood something. I'm expecting user xyz to be able to see the public folder. Grateful for any pointers. Thanks, Keith

[Dovecot] Authentication failed, failure to login after changed password
by Vinit Jain 28 Aug '09

28 Aug '09

Hi, I have installed dovecot 1.0 mail server on debian linux. I am using unix authentication to login the mail accounts. We developed one web mail application whcih use imap protocol and send mail fro sending the mail. We are creating unix user through our application and able to login to the mail account succesfully and do all opeartion on that. But once user change password through our application or directly on unix commaqnd prompt then we are unable to login to mail application it gives authentication failed error. Even user can use ssh, sftp after changing password. Everything works except mail account. Here is the error excerpt from log files (mail.log and auth.log ) respectively. Aug 26 10:58:37 digibeanz dovecot: imap-login: Aborted login (1 authentication attempts): user=<child2>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, TLS Aug 26 12:22:00 digibeanz dovecot-auth: pam_unix(dovecot:auth): authentication failure; logname= uid=0 euid=0 tty=dovecot ruser=child2 rhost=127.0.0.1 user=child2 Please help me.

[Dovecot] Question about ACL/flags
by Eric Jon Rostetter 28 Aug '09

28 Aug '09

Okay, I'm cruising the wiki, and it is at best confusing to me. Maybe someone on the list can help me out quickly? Here is what I have: dovecot 1.1.18, mbox format, currently no acl/namespace/etc. All works great. What I want to be able to do: Have an email account (or folder or mailbox) which can be accessed by several people (say 3) with per-user seen flags. That is, say 3 people all access the mail but each user has their own seen flag for the messages. This would hopefully be done with mbox still, if possible, but I'm willing to try a mixed mbox/maildir setup if required to accomplish the goal. Questions: 1) Can I do this with 1.1.18, or do I need to upgrade? 2) Do I need to set :CONTROL in mail_location, and if so, what should I set it to, and what does this control exactly (more precisely, does this info need to be HA or not, etc) Is this where the seen flag info will be stored (or is that in INDEXES)? 3) Can I do this with mbox only, or do I need maildir, or does it depend on dovecot version? 4) Any additional help you can give me... I basically understand the ideas behind it all, but from the wiki I'm confused exactly what I need to do, and what version I might need. (If the wiki example is for dovecot 1.2+, does that mean it won't work in 1.1, or just that it has to be done differently, etc). Any help (clearing up my obvious confusion) would be appreciated... Step by step directions would be even better! :) -- Eric Rostetter The Department of Physics The University of Texas at Austin This message is provided "AS IS" without warranty of any kind, either expressed or implied.

[Dovecot] runaway imap processes
by rpyne＠kinfolk.org 27 Aug '09

27 Aug '09

I am running dovecot (1.2.3) with postfix (2.6.3), postfixadmin (2.1.0), maia mailguard (1.0.2) and squirrelmail (1.4.19) on Linux (kernel 2.6.27.8). I have an ongoing problem with imap processes that hang and eat all available cpu. I try killing them and they won't die. The only way to get rid of them is to reboot the server. Any help with this will be greatly appreciated. I really need to get this solved as it has been an ongoing problem for more than a year.

[Dovecot] TLS / SSL mixed w/ plaintext auth and virtual hosting
by Nathan M 27 Aug '09

27 Aug '09

Traditionally this server has only accepted plaintext authentications; however, we want to change that and enable TLS/SSL. The challenge is the server has hundreds of IP addresses it binds to to listen on ports 110/143. Enabling TLS/SSL is not an option because as this is a virtual hosting environment, if a connection comes in on any other hostname other than the specific one tied to the crt all mail clients will throw a mis-matched certificate error if TLS is initiated by the client, and a surprisingly large number of customers have "use TLS if available" selected in their clients. According to most of the suggestions on the list, I've setup 2 dovecot instances. The first listening on *:110 and *:143, and the second listening on 10.0.0.2:993 and 10.0.0.2:995. This works great for SSL support; however, I would also like to offer TLS to connections coming in on a single IP address. Because the server has hundreds of IPs, with new IPs adding all the time, seemingly the only way would be to configure every one of these IPs (as they occur) into the primary dovecot.conf file, and then only setup the single IP that's handling SSL/TLS in the dovecot-ssl.conf (the conf file the SSL/TLS instance loads). This can be time consuming and has no way to automate. It would be terrific if one of the following exists, or potentially could exist: 1. Ideal scenario. A config option which tells TLS to only respond on certain IPs. In our case if a connection attempts to initiate TLS on any IP address except 10.0.0.2, it would respond with no TLS support. This would be ideal as we could continue running just a single dovecot instance. 2. Secondary scenario. A way to exclude an IP from being bound to. Something like the following to bind to all except 10.0.0.2 listen = *:110, -10.0.0.2 As is, based on my understanding of the config neither of these are options. Any support for adding either of these options, or alternate ideas anyone might have? - N

[Dovecot] Fatal: Dovecot is already running
by Jim 27 Aug '09

27 Aug '09

We had a power outage here last night, and when the server rebooted, dovecot was unable to launch properly: 8/27/09 2:08:25 AM com.apple.SystemStarter[31] Starting dovecot 8/27/09 2:08:25 AM com.apple.SystemStarter[31] Fatal: Dovecot is already running with PID 143 (read from /usr/local/var/run/dovecot/ master.pid) 8/27/09 2:08:25 AM SystemStarter[31] dovecot (115) did not complete successfully When I checked the server and saw this, I simply started it via the command line, and it came right up, but of course that was hours later. Since this script is only called at startup, would it be safe to just delete master.pid before trying to start dovecot? The server here is OS X 10.5.7, dovecot is being called via a StartupItem. I had originally used a LaunchDaemon for starting this, but ran into issues because MySQL wasn't always ready when dovecot tried to launch, and dovecot would never come up as a result. Below is the script I'm using, which includes a check for MySQL: #!/bin/sh # A script to automatically start up policyd on system bootup . /etc/rc.common ConsoleMessage "dovecot - setting up" # wait for mysql start up IS_ALIVE=`/usr/local/mysql/bin/mysqladmin -umysql ping | grep -c 'alive'` while [ "$IS_ALIVE" != "1" ]; do sleep 5 ConsoleMessage "dovecot - waiting for MySQL" IS_ALIVE=`/usr/local/mysql/bin/mysqladmin -umysql ping | grep -c 'alive'` done StartService () { ConsoleMessage "Starting dovecot" /usr/local/sbin/dovecot } StopService () { return 0 } RestartService () { return 0 } RunService "$1"

[Dovecot] missing .dovecot.lda-dupes file in LDAP/virtual user environment
by Claudio Tassini 27 Aug '09

27 Aug '09

Hi, I'm running a postfix/dovecot/ldap setup and it works quite fine. I am now trying to setup a global sieve script to forward all incoming mails to a local user for vacation management (gnarwl). I can't user the vacation extension of the sieve script itself because it is not configurable enough (each user has his vacation message and status stored in LDAP). The problem is that when deliver runs the sieve script, it tries to create the .dovecot.lda-dupes inside the user homedir, even if I didn't use the vacation feature in the script. This is the error I get: Aug 27 15:19:23 myhostname deliver(user1(a)mydomain.it): file_dotlock_create( mydomain.it/1/user1(a)mydomain.it/Maildir/.dovecot.lda-dupes) failed: No such file or directory Important sections from config: master.cf deliver: dovecot unix - n n - - pipe flags=DRhu user=mail:mail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${recipient} dovecot -n extract: mail_location: maildir:/maildirs/%h auth default: passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: passwd userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf plugin: quota: maildir:User Quota acl: vfile:/etc/dovecot/acls sieve_global_path: /etc/dovecot/default.sieve and extract from dovecot-ldap.conf : user_attrs = mailMessageStore=home,maildirquota=quota_rule=*:backend=%$ user_filter = (&(|(mail=%u(a)mydomain.it )(mail=%u)(mailalternateaddress=%u)(mailequivalentaddress=%u))(objectclass=mailrecipient)(imap-status=true)) pass_attrs = mail=user,userPassword=password,mailMessageStore=userdb_home,mailquota=userdb_quota_rule=*:backend=%$ pass_filter = (&(|(mail=%u(a)mydomain.it )(mail=%u)(mailalternateaddress=%u)(mailequivalentaddress=%u))(objectclass=mailrecipient)(imap-status=true)) The global sieve script: require ["copy"]; if not address :is "to" "gnarwl@localhost" { redirect :copy "gnarwl@localhost"; } The format of the "home" userdb extra field as returned from the ldap is " mydomain.it/1/user1(a)mydomain.it/Maildir/" . This value is normally appended to the mail_location global parameter ( /maildirs ) to build a path of the form "/maildirs/mydomain.it/1/user1(a)mydomain.it/Maildir" . This works flawlessly when delivering mail, but seems that the sieve plugin ignores the "mail_location" and tries to write the dupes file in the home as it is returned from the ldap. Questions are: 1) Is it normal that lda tries to create the dupes file even if I am not using the vacation extension at all? 2) How can I tell LDA/sieve/whatever to prepend the mail_location to the home directory of the user for proper creation of the file? Many thanks in advance. -- Claudio Tassini

Hi there! I have two DNS records mail1.domain.tld mail2.domain.tld I have issued SSL server Certificates for both my domain names. Is it possible to tell dovecot to use both , depending on client access; clients using the mail1.domain.tld be served by the mail1.domain.tld .key and .cert and those using mail2.domain.tld be served by the mail2.domain.tld .key and .cert Thanks in advance Dimitrios

[Dovecot] Authentication failed, failure to login after changed password
by linuxvinit 27 Aug '09

27 Aug '09

I have installed dovecot 1.0 mail server on debian linux. I am using unix authentication to login the mail accounts. We developed one web mail application whcih use imap protocol and send mail fro sending the mail. We are creating unix user through our application and able to login to the mail account succesfully and do all opeartion on that. But once user change password through our application or directly on unix commaqnd prompt then we are unable to login to mail application it gives authentication failed error. Even user can use ssh, sftp after changing password. Everything works except mail account. Here is the error excerpt from log files (mail.log and auth.log ) respectively.

[Dovecot] Weird mirgration problem
by Stewart Dean 27 Aug '09

27 Aug '09

Most likely non-Dovecot, but I'd appreciate any comments on WTF might be going on here. Preparatory to migration from mbox to maildir format on our AIX mail server, I am migrating from the JFS filesystem (being deprecated by IBM) to JFS2 to better handling the jump in the number of files. Two nights ago, I took the first step and migrated the IT homedir filesystem: copied it to a scratch disk, melted down the FS and recreated it as a JFS2 FS. In order to keep changes from happening to it during this process, I killed off DC (dovecot -n ouput is appended to bottom of this note) and dropped the export of the FS. The bringup was a little ragged due to time constraints and the fact that I had trouble re-establishing the export. FWIW, the homedirs and Inobx FSes are mounted by a majordomo mailing list server. Everything went fine except for an anomaly with old pre-existing mailing list emails in my INBOX and that of a few others. Note that the inbox FS wasn't touched by this process, just the homedir FS for the IT department. What happened there was that the mbox headers went from looking like this: From owner-hcrcstaff Mon Aug 24 14:53:29 2009 >From majordom Mon Aug 24 14:53:29 2009 the rest of the normal header here To looking like this: From owner-hcrcstaff Mon Aug 24 14:53:29 2009 Status: RO X-UID: 871476 Content-Length: 1915 >From majordom Mon Aug 24 14:53:29 2009 normal header lines here It appears that the Status, X-UID and Content-Length lines were inserted just under the top line of the header in every old mailing list mailing email header...and not in any other mailing As a result of this, = these emails appear in the email client's TOC listing with blank Sender and Subject fields, even though the data for that is properly in the header further down = This happens both in TBird and Horde webmail. = All these emails (some 300, going back to 2008) are listed in one block, in proper order for their actual date, as having the datestamp of 5AM, when I was bringing everything back up. Unfortunately, because of time pressures, I can say exactly what I was doing then. = I never took down my TBird session while doing this process...and I imagine that others, who haven't said anything and presumably didn't have this problem, left their TBird or IMAP email client up... Does this anomaly bring to mind anything to you? FWIW, I plan on doing the students' homedir FS early tomorrow morning. This time I'll be more scrupulous about tracking things AND I will take down the mailing list and login servers to remove the possibility that they had something to do with this... dovecot -n output # 1.1.15: /usr/local/etc/dovecot.conf # OS: AIX 3 0001378F4C00 listen: *:143 ssl_listen: *:993 disable_plaintext_auth: no verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login login_processes_count: 12 login_max_processes_count: 774 max_mail_processes: 1024 verbose_proctitle: yes first_valid_uid: 200 mail_location: mbox:~/mail:INBOX=/var/spool/mail/%u:INDEX=/var/dcindx/%u mbox_write_locks: fcntl mbox_dirty_syncs: no auth default: passdb: driver: pam userdb: driver: passwd -- ==== Once upon a time, the Internet was a friendly, neighbors-helping-neighbors small town, and no one locked their doors.

[Dovecot] fchown() failed
by Arthur Dent 26 Aug '09

26 Aug '09

Hello all, I'm not sure if this question is better posed to a Fedora group because I have only had this problem since I upgraded from F9 to F11, but I figured that the specialised knowledge here might help me more... I have been getting these entries in syslog since upgrading. Today for instance I got: **Unmatched Entries** dovecot: Dovecot v1.2.0 starting up (core dumps disabled): 1 Time(s) dovecot: IMAP(mark): fchown() failed with file /home/mark/Mail/.imap/INBOX/dovecot.index.log.newlock: Operation not permitted: 1 Time(s) dovecot: IMAP(mark): fchown() failed with file /home/mark/Mail/.imap/INBOX/dovecot.index.tmp: Operation not permitted: 1 Time(s) and yesterday I had: **Unmatched Entries** dovecot: IMAP(helena): fchown() failed with file /home/wife/mail/.imap/INBOX/dovecot.index.tmp: Operation not permitted: 1 Time(s) dovecot: IMAP(toby): fchown() failed with file /home/son/mail/.imap/INBOX/dovecot.index.cache.lock: Operation not permitted: 1 Time(s) dovecot: IMAP(toby): fchown() failed with file /home/son/mail/.imap/INBOX/dovecot.index.log.newlock: Operation not permitted: 1 Time(s) dovecot: IMAP(toby): fchown() failed with file /home/son/mail/.imap/INBOX/dovecot.index.tmp: Operation not permitted: 3 Time(s) The permissions are as follows: ls -la /home/mark/Mail/.imap/INBOX/ total 328 drwx------. 2 mark mark 4096 2009-08-18 15:32 . drwx------. 84 mark mark 4096 2009-03-05 21:53 .. -rw-------. 1 mark mark 7472 2009-08-18 15:32 dovecot.index -rw-------. 1 mark mark 286720 2009-08-19 11:46 dovecot.index.cache -rw-------. 1 mark mark 5380 2009-08-19 12:43 dovecot.index.log Those of wife and son are similar. As I access my mailbox several times a day (and certainly did yesterday) from several different mail clients I am surprised that the error count is only 1 for most the above entries. Is this being caused by some sort of cron job (logrotate perhaps)? Any ideas? All help / suggestions gratefully received... Thanks Mark

[Dovecot] Load spikes on NFS server, multiple index updaters.
by Jorgen Lundman 26 Aug '09

26 Aug '09

We are occasionally experiencing trouble where the NFS server's load will shoot over 60+. (Normal of sub 1.0). I have been hunting this for a while, and I believe it comes down to "deliver". System setup: NFS servers: x4540 Solaris 10 x64 ZFS over NFS. NFS clients: Solaris 10 x64 postfix-2.4.1 with dovecot-1.1.11 deliver. What appears to happen, when I check for nfsstat per process, is that I see 4 processes (in this case on vmx04) taking up majority of NFS ops: root@vmx04:/var/tmp# ./nfsclientstats.pl process read write readdir getattr setattr lookup access create remove rename mkdir rmdir 24303 0 0 1 19 0 190 171 0 0 0 0 0 24551 0 0 1 18 0 180 162 0 0 0 0 0 26099 0 0 1 18 0 180 162 0 0 0 0 0 295 0 0 1 18 0 180 162 0 0 0 0 0 6793 3 0 0 0 0 5 5 0 0 0 0 0 7234 0 1 0 2 0 9 9 0 1 0 0 0 Checking what these processes are doing, I find the following happening: 26099: getdents64(8, 0xCE7A4000, 8192) = 8136 26099: stat64("/export/censored/mail/cur/1223013930.V4700010I69f93eM483098.vmx02.unix:2,S", 0x08047930) = 0 26099: stat64("/export/censored/mail/cur/1222066290.V4700007I67562bM241839.vmx04.unix:2,S", 0x08047930) = 0 26099: stat64("/export/censored/mail/cur/1225325373.V4700008I94a1f9M286935.vmx04.unix:2,S", 0x08047930) = 0 26099: stat64("/export/censored/mail/cur/1236170307.V4700002I67ca03M310418.vmx06.unix:2,", 0x08047930) = 0 26099: stat64("/export/censored/mail/cur/1223581462.V4700011I69ffd6M720814.vmx02.unix:2,S", 0x08047930) = 0 Very well, so it is rebuilding the dovecot.index, or recalculating the user's quota usage. Is the directory large? root@vmx04# ls -l /export/censored/mail/cur/|wc -l 199626 You bet! But what is annoying is that if I also check process 24303, 24551 and 295, they are scanning the SAME user's directory. 295: stat64("/export/censored/mail/cur/1230544947.V4700004I11d1d7fM492433.vmx04.unix:2,S", 0x08047930) = 0 295: stat64("/export/censored/mail/cur/1223003964.V4700007I68932dM763546.vmx04.unix:2,S", 0x08047930) = 0 So, in vmx04 we have 4 processes working in one user's giant directory, and on the other vmx clients, many more. Could the semantics to 're-computing dovecot.index' be done such that the first "deliver" process locks it to do the work, and sub-sequent deliver processes will return temporary failures, until the work has finished. Has it been already addresses in dovecot-1.1.18? Advice please.

[Dovecot] scalability and arhive ideas
by fernando＠dfcom.com.br 25 Aug '09

25 Aug '09

Hi, I´m reading the past topics related to archive and scalability of dovecot, they are all very interesting. Here, I´m using two dovecot proxies in front of five storages pairs, and we split the domain´s accounts among those servers. So, we can share the i/o load and if one server goes down only few accounts of the domain stops (not all of them). But, we began to have space problems - and the solution would be insert more and more storage servers. So I was searching for some archive solutions (hard links - at S.O level, or some dovecot extension). A friend told me that he knows an ISP that share even the mailbox of the users among many servers - this is very weird and (at same time) very interesting approach. Instead of put all messages into one maildir and this maildir into one server, this "maildir" (?) is spplited among many servers - so, if one servers fails the account is still acessible and they move old/big messages to a new "cheap" storage - archiving transparently. Well, maybe it´s an stupid idea, but couldn´t dovecot imap/pop proxy do the same ? I mean, imagine the following scenario: 1- Proxy does an user account sql - today the return is (among other data), the final server IP, but it could be the storage servers for this account 2- Proxy does parallel connections (instead of today´s one connection with the final server). Retrieve the messages and caches locally where the message is. If the cache is lost, no problem, it just connects again and re-cache them. 3- When a message is deleted/flagged, etc - it has the cache (allowing it to know where send the command to), when a message inserted (as sent folder) - the system can have the 'default storage' where the messages are delivered and saved to - the other storages are just for archiving (or even a round-robin delivery !? - hard to control). Problems: 1- Have the cache at proxy level. 2- Quota calculation (how the delivery process can check this ?) 3- Maybe mixing proxy connection and this new approach is not easy way. 4- the more servers, the more time waiting their answers (imagine one of them answering slowly). Advantages: 1- No local mounts at storage level - (as nfs and other network mounted partitions). 2- Servers independency - if space is at a critical value, insert a pair of servers, move messages there, insert the servers in the sql answer (server1, server2, server3, ... , serverN). 3- Scalability - the more servers, the more i/o load you can share. Well, sorry for the long post...but I hope to collaborate with some ideas (even if they are stupid :( ) Regards, Fernando Bertasso Figaro

[Dovecot] dovecot-auth failed: Not enough space
by S. A. Woltering 25 Aug '09

25 Aug '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear all, I've been trying to get a Dovecot IMAP service running under HP-UX 11.23, IA64. The system has 6GB of spare space under /var and at least the same amount of RAM free at the current time. I've compiled from the latest source (1.2.4), using the following options: # CC="/opt/aCC/bin/aCC" ./configure --prefix=/opt/dovecot ... usual make && make install My config file follows at the end. In essence, every time I attempt to start dovecot (/opt/dovecot/sbin/dovecot, with no options) I get the following on the command line: Warning: Last died with error (see error log for more information): Auth process died too early - shutting down Info: If you have trouble with authentication failures, enable auth_debug setting.

[Dovecot] LDAP: Connection lost to LDAP server, reconnecting
by McShel 25 Aug '09

25 Aug '09

Hi! Sorry by my english. Set Postfix + dovecot + AD + ldap, everything works well, but appears in the logs, every 15 minutes: auth(default): Error: LDAP: Connection lost to LDAP server, reconnecting Standart limit ldap connect to AD 15 minutes. Can somehow fix this problem without increasing the time of connection to the AD?

[Dovecot] Aborted: Worker is buggy

A simple 'killall dovecot-auth' takes care of it and the server is able to start. I'm not using anything exotic, dovecot config below. The most curious fact is that we have identical servers running the same version of dovecot (1.2.3, happened under 1.2.1 as well) talking to the same MySQL database and both develop the problem at the same time. The database is under considerable stress at the time this occurs as the policyd tables are being cleaned. But this happens twice per hour and only sometimes does dovecot have trouble. I'm working to move the policyd database elsewhere, but of course this shouldn't happen in any case. Any help would be much appreciated. Thanks!

[Dovecot] Per user namespace
by Ashley M. Kirchner 25 Aug '09

25 Aug '09

I'm in the process of upgrading an old server which is running uw-imap to a new one running Dovecot. With the old machine, unfortunately, my users had the opportunity to store their e-mails in various locations. For example, some have their mail boxes stored in ~/mail/[various mbox files], others ALSO have a ~/mail/clients/[various mbox files] and yet others simply stored them in their ~/ path (thanks to the old IMAP). Is there a way to create per-user namespaces? I don't want to create a "mail/", "mail/clients/", etc., etc. global name space that will end up showing up on everyone's mail client, nor do I want to individually change each user's setup (and rewrite their .subscriptions file). Any solutions here, or am I SOL? AMK4 -- W | It's not a bug - it's an undocumented feature. +-------------------------------------------------------------------- Ashley M.

Hi Timo, thank you for your reply. I take the configuration from http://www.linuxmail.info/postfix-dovecot-ldap-centos-5/ especially the dovecot-configuration for passdb and userdb. As you mentioned in your reply I added the userdb ldap with a symbolic link on the original dovecot-ldap.conf: userdb: driver: ldap args: /etc/dovecot-ldap-userdb.conf but with no success. Any hints? I have another question: Does Dovecot expect a special "field type" for the ldap quota field (for ex. integer)?

[Dovecot] Dovecot LDA
by Wouter van der Schagt 24 Aug '09

24 Aug '09

Good morning, Still not having luck to get the LDA to work, using Qmail + Vpopmail and read the wiki. I'm using: auth default { mechanisms = plain passdb vpopmail { } userdb vpopmail { } user = vpopmail count = 1 ssl_require_client_cert = no } Which work well for authenticating users, however when using the following in a .qmail file: |/var/qmail/bin/preline -f /usr/local/libexec/dovecot/deliver -d $EXT@$USER I get the following error message: Error:_userdb_lookup:_connect(/usr/local/var/run/dovecot//auth-master)_failed:_No_such_file_or_directory/ Eventhough it should have been created (I think) in the protocol lda section of the config file. I specifieD: auth_socket_path = /var/run/dovecot/auth-master However I thought since using vpopmail I don't need to use the auth-master ? or am I missing something? Sincerely, - Wouter van der Schagt

As in my configuration could define multiple LDAP servers? I have two servers with Active Directory, a PDC and a BDC, but I would specify both in the same configuration. for when the ldap server 1 has problems, authenticating against Ldap 2 . Thanks Michel

[Dovecot] Problems with dovecot/sendmail combi.

Hi, I am really stuck here. I am trying to setup imap for an external mail server. I have a freebsd server running sendmail / dovecot. I am transfering the existing mail from an exchange 2003 server to the mailserver using imapsync. This works fine, but gives errors when it tries to make a submap, also thunderbird gives an error "Mailbox doesn't allow inferior mailboxes" when I try to make a submap. I found out that it has something to do with the mbox not able to have submaps and there should be a workaround using namespaces. I tried several setups but keep getting errors.

[Dovecot] sieve vacation response
by Jure Pečar 24 Aug '09

Hello, we're implementing a dovecot 1.2.1 with sieve 0.1.7 and managesieve 0.11.7. We're having problems with creating sieve scripts so that vacation works. Our script looks like this: require ["fileinto", "vacation"]; if address :matches ["To", "Cc"] "*someone(a)example.com*" { if not header :matches "X-Spam-Status" "Yes*" { vacation :days 1 :subject "test" "autoresponder test."; keep; } } And when sent and delivered to someone(a)example.com, we get this in the log: dovecot: deliver(username): sieve: msgid=<...>: discarding vacation response for message implicitly delivered to <username(a)fqdn.hostname.com> Our final recipients are in the form of username(a)fqdn.hostname.com; it looks like this is being matched in sieve as address. But we want to match against original recipient address, not address after alias expansion. Any ideas? -- Jure Pečar http://jure.pecar.org http://f5j.eu

Hello, all. I'm using Dovecot 1.0.15 on our internal mail server and I'm seeing a high load from one of our users.

I'ld like to understand why we're seeing this and whether the blame should be put on Thunderbird or on Dovecot. Has anyone ever seen this before? Emmanuel

[Dovecot] SOT: Removing _extra_ linefeeds from MSOutlook(?) messages
by Roderick A. Anderson 24 Aug '09

24 Aug '09

I realize this is sorta off topic but my searches using Google have got me mostly no where. So I thought I'd ask here as there is a lot of _past Postfix_ mail handling issues discussed. The issue is; I have to deal with a lot of messages that come from MS Outlook users and sometimes they are replies to replies to replies ... My reading indicates it has a little to do with HTML composed messages and the format=flowed declaration. This produces messages with *lot* of extra line feeds. Makes the messages nearly unreadable -- in Thunderbird. I'm sure others have got two line (sentence) messages that took 6+ lines to display. Then when they are replies or forwards it is even more. Every line gets two NLs/CRLFs. Anyone have a suggestion of how to _strip_ multiple line feeds from a message? Is there a sieve method/way? I don't want to fiddle with all the users emails just my own. Pointers, ideas, clues? \\||/ Rod --

[Dovecot] critical X-UID reordering problem after upgrade from 1.1 to 1.2
by robh＠cs.indiana.edu 23 Aug '09

23 Aug '09

We upgraded our imap server hardware and went from dovecot 1.1.3 to 1.2.3 in the process and have been having a critical problem since. I believe I've tracked it down to X-UID reordering that dovecot seemed to do to the mbox format (I know, I know...) inboxes. The problem has manifest itself in several ways with different mail clients but the general problem is that the mail clients have gotten confused about which message is which. For example, thunderbird will display the wrong information about a message in the header listing but then show the correct data in the message display window when you actually open the message. As you can imagine, this is causing all kinds of user problems. Here is a very simplified explanation of what I'm seeing. Imagine that the inbox had 5 messages with X-UID values 1, 3, 5, 6, and 9 before the upgrade. After the upgrade the X-UIDs were reordered so these same 5 messages now might have X-UID values of 1, 2, 3, 4, and 5. Thunderbird then shows the summary information like this: Subject/Sender/Date for message 1 Subject/Sender/Date for message 2 Subject/Sender/Date for message 2 Subject/Sender/Date for message 4 Subject/Sender/Date for message 3 Now, if you actually open the 5th message it shows the right message body but the summary information is for the message that *used* to have X-UID 5 (which is now the 3rd message). So, the thunderbird cache is out of sync and I can fix it by removing the .msf file for that mailbox but, as you can imagine, the prospect of getting all the users to remove their .msf/.pst/?? cache files is daunting, to say the least. I've seen discussions about similar things happening with mbox format inboxes but they all seem to be in the context of some ancient 0.xx version of dovecot with known mbox processing bugs. But, I went from a reasonably current 1.1.3 version to 1.2.3. Right after seeing the problem, I upgraded to the just released 1.2.4 but either that didn't address the problem or, if it did, the reordering damage was already done by version 1.2.3. So, my 2 questions are: 1) Anyone know why this would have happened and whether it is a dovecot problem or something I botched? I folded all the local config changes I had made to the 1.1.3 conf file into the stock 1.2.3 conf file so they should have been identical modulo changes in the distro. And, our local config changes are really minimal. 2) Is there anything I can do now other than getting all the users to remove their .msf/.pst/etc files? It sure would be grand if there was something I could do on the server side that would magically cause all the client-side caches to be invalidated. I'm hesitant to strip the inboxes of all the X-IMAPbase and X-UID lines because I'm not sure what the ramifications of that might be. Here are some other random thoughts in case they might be related: - The old server was running 32bit RHEL4 and the new one 64bit RHEL5 - I'm using the pre-built dovecot rpms from atrpms.net - The dovecot index cache is kept in /var/cache/dovecot/indexes and I did not copy that over from the old server to the new assuming it would just be rebuilt.

[Dovecot] Released Sieve v0.1.12 and ManageSieve v0.11.9 for Dovecot v1.2.4
by Stephan Bosch 21 Aug '09

21 Aug '09

Hello Dovecot users, I finally managed to make new releases of Sieve and ManageSieve for the recent Dovecot v1.2.4 release. The ManageSieve release is important to match login proxy API changes in Dovecot; older versions will not compile against the new Dovecot release. The new Sieve release first includes the new date extension, which allows matching against date values in header fields and the current date-time at script execution. Changelog Sieve v0.1.12: + Testsuite: added support for testing binaries stored on disk. + Implemented the new date extension. This allows matching against date values in header fields and the current date at the time of script evaluation. Changelog ManageSieve v0.11.9: * Adjusted to changes in the Dovecot login proxy API. This release therefore depends on Dovecot v1.2.4. + Reintroduced ability to abort SASL with "*" response. Latest ManageSieve specification includes it. The releases are available as follows: Sieve: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.12.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.12.tar.gz.sig ManageSieve (package + patch): http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.9.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.9.tar.gz.s… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.4-managesieve-0.11.9.diff.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.4-managesieve-0.11.9.diff.g… Have fun testing the new releases and don't hesitate to notify me when there are problems.

I'm trying to setup deliver as an LDA for system users. I've read http://wiki.dovecot.org/LDA/Sendmail which handles virtual users. I don't see a README for what I need. I want sendmail to accept the mail and then hand off to deliver with sieve plugin. Deliver should look in the users home directory which is found in /etc/passwd for the sieve-script to see what to do with it. If the sieve-script DNE, then just deliver to INBOX(from dovecot.conf). Any help would be appreciated.

[Dovecot] Oops!
by Daniel L. Miller 20 Aug '09

20 Aug '09

I was testing a new webmail client - like an idiot, against my own mailbox, instead of a test mailbox (or even a separate server) - and my Inbox got wiped. Fortunately I backup our mails nightly, so I only lost a couple from today. No idea how the wipe occured - I didn't INTENTIONALLY perform a delete + purge...but it happened. Is there a way of configuring Dovecot to ensure that any delete operation specified by a client results in a "move to Trash" as a precaution? Instead of relying on the client to perform it? -- Daniel

I'll read my mails once in a while though. * acl: When looking up ACL defaults, use global/local default files if they exist. So it's now possible to set default ACLs by creating dovecot-acl file to the mail root directory. + imap/pop3 proxy: If proxy destination is known to be down, fail connections to it immediately. + imap/pop3 proxy: Added proxy_timeout passdb extra field to specify proxy's connect timeout. - Fixed a crash in index file handling. - Fixed a crash in saving messages where message contained a CR character that wasn't followed by LF (and the CR happened to be the last character in an internal buffer). - v1.2.3 crashed when listing shared namespace prefix. - listescape plugin: Several fixes. - autocreate plugin: Fixed autosubscribing to mailboxes in subscriptions=no namespaces.

[Dovecot] dovecot/sieve current date
by bart 19 Aug '09

19 Aug '09

Hi, Is there a way in sieve to get the current date, preferably in YYYYMMDD format? To what I've found it's hard to achieve. I have tried including a :global sieve script in which I would set the current date to a certain variable and overwrite this included script every day. But to my disappointement variables set in an included script do not exist in the original script... In fact what I want to achieve is that some actions like forwarding or vacation messages are performed from a certain date untill another date. Which would allow a user to define a timeperiod in which the autoreply or forward should be done and automatically stop without updating the sieve script again. Comparing start and stopdate is cake, but just getting today's date seems to be a hassle, any ideas? regards, bart

[Dovecot] Restoring backup?

I have understood correctly when thinking that all I need to do in order to restore mails, is to just copy the old maildir folder to the location where mail_location is pointing to and dovecot will find all the mails and display the old mails?

[Dovecot] alias does not work
by denis 18 Aug '09

18 Aug '09

Hi, Thank you to everyone who helped me get near the goal. Remains a problem is that aliases don't work. The problem is that in the configuration of alternc, the mails are seen as aliases in the form user_domain.tld. In a second time, a match is made to see if an "real" alias exists. postmap -q test(a)lists.test.net mysql:/etc/postfix/mydomain.cf test-owner_lists.collectifs.net postmap -q test-owner_lists.test.net mysql:/etc/postfix/myalias.cf "| /var/lib/mailman/mail/mailman owner test" With my configuration, this second part doesn't work. Perhaps the simplest is to ask to deliver the mail to user_domain.tld except of user(a)domain.tld in master.cf ? Thanks Denis # main.cf virtual_alias_maps = proxy:mysql:/etc/postfix/myalias.cf, hash:/etc/aliases virtual_mailbox_domains = mysql:/etc/postfix/mydomain.cf virtual_mailbox_maps = proxy:mysql:/etc/postfix/myvirtual.cf virtual_transport = dovecot dovecot_destination_recipient_limit = 1 # master.cf dovecot unix - n n - - pipe flags=DRhu user=www-data:www-data argv=/usr/lib/dovecot/deliver -d $(recipient)

[Dovecot] Gotchas in switching from one server to another without impacting users?
by Gary Chodos 18 Aug '09

18 Aug '09

We have to replace one mail store (foo.example.org) with another (bar.example.org) I rsync'd the maildirs from foo to bar today and the plan is to hold all delivery (in the SMTP server) on foo over the weekend, rsync again (this time it should be much faster since the large xfer already occurred today), then flush the SMTP queue on foo towards bar, direct all new deliveries to bar.example.org. Users currently access their IMAP mailboxes via imap.example.org. I plan to just 'flip the switch' at DNS so imap.example.org points to bar.example.org (instead of foo.example.org) so users don't have to change anything on their end and should not even notice this change. Is there anything else I should think about to mitigate users noticing a change? Does the fact that the mail filenames include 'foo.example.org' in the file name (while new deliveries to bar.example.org will include that new hostname) spell trouble later on or can I ignore it? Is there a more efficient way to achieve my goal? And finally, dovecot on foo.example.org is 1.1.7 while the new server is running 1.1.16. I don't think that should be an issue, but mentioning it just in case. Thanks! -- GC

[Dovecot] Public namespaces with global ACLs 1.2+
by Thomas Leuxner 18 Aug '09

18 Aug '09

Hi, I'm having trouble to get ACLs working in a more restrictive way with namespaces. I would like to grant certain users the ability to create new mailboxes in a public namespace e.g. "Public/Newsletters" etc. It works when I add the users to a ".DEFAULT" ACL file like this: user=username lrwk Anyway I'd like to limit their permissions on the Namespace "Public", or even better - being more restrictive, on "Public/Newsletters". Neither global ACL files for "Public" nor "Newsletters" nested in the global path seem to work. For now only the .DEFAULT ACL (/var/vmail/ domain/etc/acls/.DEFAULT) seems to mitigate the problem which is undesirable. dovecot -n excerpt: plugin: acl: vfile:/var/vmail/%d/etc/acls:cache_secs=300 Thanks Thomas

[Dovecot] Dovecot and LDAP-Quotas
by south africa 17 Aug '09

Hi all, I have configured Dovecot as a POP/IMAP-Server in front of a Postfix-Server. Every thing works without one thing: LDAP-quotas The main-quota-rule works: quota_rule: *:storage=8M Only the LDAP-quota won't be used by Dovecot: user_attrs = msRADIUSFramedIPAddress=quota_rule=*:storage=%$k I have to use the special LDAP-field "msRADIUSFramedIPAddress" because my W2003 domain controller don't have a regular quota field. This LDAP-field is the only "free integer" LDAP-field. Could anyone please give me a hint?

[Dovecot] BUG: mbox_snarf causes message duplication when two IMAP connections are open
by Robert Lazzurs 17 Aug '09

17 Aug '09

Hello, I have used dovecot to replace an ageing wu-imap installation using the mbox_snarf plugin however I have noticed that when we have more than one client checking the INBOX we then have messages being duplicated in the INBOX. Below is the configuration used as requested in the bug report page. I have confirmed that the duplicates are being caused by dovecot by doing an strace of both processes that have both the INBOX (/mail_home/$username/INBOX) and mail spool file (/var/spool/dovecot/$username) open and delivering a new message through exim to the mail spool file in /var/spool/dovecot/$username. I then see in strace first one process check the spool and copy the message over and then the other processes do the same. If anyone requires any further information to confirm this bug please let me know. Kind regards.

[Dovecot] More Migration Questions
by Richard Hobbs 17 Aug '09

17 Aug '09

Hello, I was on here a month or two ago asking lots of questions about migrating from uw-imapd/qpopper/mbox to dovecot/maildir. I am now at the stage where i'm trying to convert all my emails, but i have a few questions... Where should i convert my mbox mailboxes into? "/home/username/Maildir/" or "/somewhere/maildirs/"? Does it actually matter? Is there a standard location that they *should* go? I've tried converting them into "/somewhere/maildirs/username/", but then i found a dovecot page that says they are usually stored in "/home/username/Maildir" so now i don't know where to put them! Also, having converted the mbox files into maildir files, i do seem to have one email per file, as intended, but the files have names like "1250253965.000586.mbox,S=8167,W=8427:2,S". Should they have the word "mbox" in their filename if they are maildir files? Finally, it appears that our existing IMAP users (all mbox) have mailboxes stored simply in their home directory, not necessarily inside the "~/mail/" directory - is this going to be a problem? The command i'm using to convert is this one: ./migrateuser.sh username /home/username /vol2/maildirs/username This script (and the latest mb2md.py that goes with it, to preserve msg IDs) were obtained from here: http://wiki.dovecot.org/Migration/MailFormat The stage i'm at with the server overall is that uw-imapd and qpopper have been completely removed, exim is currently setup to deliver via it's own method into the mbox files in /var/spool/mail but the exim service is stopped because i'm migrating, and dovecot 1.1 is installed but stopped, and has had no configuration done to it yet whatsoever. So... any advice? Thanks in advance!

Hi, I have a couple of people bumping into an issue with their imap process crashing - from the users perspective, their mail client (thunderbird) just stops recieving new mail. It still seems to be possible for them to read their mail using squirell mail. When it crashes, it leaves behind a log message like this on the server: Aug 12 15:52:25 fury dovecot: imap-login: Login: user=<zhi>, method=PLAIN, rip=10.8.5.15, lip=10.10.0.26 Aug 12 15:52:25 fury dovecot: IMAP(zhi): Panic: file istream.c: line 99 (i_stream_read): assertion failed: ((size_t)ret+old_size == _stream->pos - _stream->skip) Aug 12 15:52:25 fury dovecot: IMAP(zhi): Raw backtrace: imap [0x49ddc0] -> imap [0x49de23] -> imap [0x49d4a6] -> imap [0x4a252e] -> imap [0x4a4691] -> imap(i_stream_read+0x48) [0x4a23f8] -> imap(i_stream_read_data+0x28) [0x4a2558] -> imap [0x4ab22e] -> imap(o_stream_send_istream+0x2e) [0x4aa63e] -> imap(maildir_save_continue+0x32) [0x443d12] -> imap(mail_storage_copy+0x6a) [0x462a1a] -> imap(maildir_copy+0x5e) [0x441d2e] -> imap(cmd_copy+0x1fe) [0x41a94e] -> imap(cmd_uid+0x78) [0x41f8d8] -> imap [0x42053c] -> imap [0x4205f2] -> imap(client_handle_input+0x3f) [0x42072f] -> imap(client_input+0x5f) [0x42127f] -> imap(io_loop_handler_run+0xf8) [0x4a5b08] -> imap(io_loop_run+0x1d) [0x4a4c1d] -> imap(main+0x620) [0x428b80] -> /lib64/libc.so.6(__libc_start_main+0xf4) [0x353e41d974] -> imap [0x4198f9] Aug 12 15:52:25 fury dovecot: dovecot: child 14759 (imap) killed with signal 6 (core dumps disabled) I was able to fairly reliably trigger the same behaviour myself by attempting to move a bunch (thousands) of emails in my account using thunderbird - I dont know exactly what it is that triggers the crash though.

[Dovecot] How to disable system users from receiving mail?
by Paul H Park 17 Aug '09

17 Aug '09

I know that login can be disable for system users and groups, but how do I refuse email for system groups? It's a bit of a security/maintenance irritation - I don't want to check for such spam mail, since that is possible. Thanks for any help!! Answer preferably given, so that I can configure it through webmin please.

[Dovecot] can't deliver with Kerberos username
by Nikolay Shopik 16 Aug '09

16 Aug '09

I've been trying to use Kerberos and PLAIN text file for authentication. I've setup deliver in postfix master.cf and make sure correct username are expanded but deliver is always told me "user unknown". I can logon into mailbox using Kerberos w/o problems and can send emails. Looks like Dovecot lookup up passwd files and not finding users which are in Kerberos realm. # 1.0.15: /etc/dovecot/dovecot.conf log_path: /var/log/dovecot.log protocols: imap ssl_cert_file: /etc/postfix/new_chained.crt ssl_key_file: /etc/postfix/mail.pem login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_greeting_capability: yes mail_location: maildir:/var/mail/store/%u dotlock_use_excl: yes maildir_copy_with_hardlinks: yes auth default: mechanisms: PLAIN CRAM-MD5 GSSAPI passdb: driver: passwd-file args: /etc/dovecot/passwd userdb: driver: static args: uid=vmail gid=vmail home=/var/mail/store/%u socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 438 user: root group: root plugin: sieve: /var/mail/store/%u/sieve

[Dovecot] Listing shared mailboxes with a domainpart
by Mathias Tausig 16 Aug '09

16 Aug '09

Hy! I am currently configuring a new mailserver using postfix and dovecot 1.2.1. The filesystem strucutre in my spool directory is user1/ user2/ domain/info/ domain/office/ user1 and unser2 are ordinary users mailboxes, the latter two contain the virtual mailboxes for info@domain and office@domain as created by postfix. I want these virtual mailboxes (all of them are in maildir format) to be shared to certain real users. I configured a shared namespace: namespace shared { separator = / prefix = shared/%%d/%%n/ location = maildir:/var/spool/vmaildir/%%d/%%n/ #I tried ths as well # prefix = shared/%%u/ # location = maildir:/var/spool/vmaildir/%%u/ hidden = no subscriptions = no list = yes inbox = no } Then I configured a dictionary to list the folders, as described in the wiki: plugin { acl_shared_dict = proxy::acl } dict { acl = mysql:/etc/dovecot/dovecot-dict-sql.conf } where /etc/dovecot/dovecot-dict-sql.conf holds map { pattern = shared/shared-boxes/user/$to/$from table = virtual_user_shares value_field = dummy fields { from_user = $from to_user = $to } } The database table consists of +-------------+------------+-------+ | from_user | to_user | dummy | +-------------+------------+-------+ | info@domain | user1 | 1 | +-------------+------------+-------+ But when I login as user1 I can neither see nor subscribe to the info@domain mailbox. In the "flat" case (sharing the user2 mailbox to user1), this setup works. I am pretty clueless how to go on. cheers Mathias

[Dovecot] Released Sieve v0.1.10 for Dovecot v1.2.2
by Stephan Bosch 15 Aug '09

15 Aug '09

Hello Dovecot users, In the last week two nasty bugs were found in the new Sieve implementation. Primarily, the include extension did not work when a compiled binary was loaded from disk. This is something that is still not tested by the test suite, giving this bug the opportunity to slip through. Also, the value matching implementation would sometimes cause a assertion failure. Other than that, various small bugs were fixed. On the more positive side, I have implemented support for the new mailbox extension (RFC 5490), which provides the means to test whether a mailbox exists. Also, it adds the :create argument to the fileinto command, which makes sure that the target folder is created before saving is attempted. Of course, this is only useful when deliver is used with the -n option. There wasn't a great need for this extension, but I could use it in the test suite and it was almost trivial to implement. In other news, I have further developed the sieve-filter command line tool. It is getting closer to a usable state, being able to filter a large number of messages in an existing mailbox, but its use is currently still very much discouraged as it tends to be very good at eating mailboxes when the user is less attentive. It needs more command line configuration options, a simulation mode to perform a dry run, and a man page that describes its use and its dangers. Changelog for Sieve v0.1.10: * Changed action execution of fileinto and keep. These changes depend on API additions in Dovecot, making this release depend on Dovecot v1.2.2 or newer. * Further developed the sieve-filter command line tool. This required a few changes to the action execution of the Sieve engine. The tool was successfully tested on folders with a few 100k spam messages. However, the commandline options are still incomplete, a man page is missing and it needs much more testing before I can recommend anyone to use this tool. + Added support for the mailbox extension. This allows checking whether a mailbox exists using the mailboxexists command and it adds the :create argument to the fileinto command to create the mailbox when it is missing. The :create feature is useless unless the Deliver LDA is run with the -n option. + Improved the testsuite with tests for message delivery. Messages stored using keep and fileinto can be fed back into the Sieve engine for verification. This includes testing of applied IMAP flags. + Updated the man pages with the new method of specifying the supported extensions using + and - (for the -x parameter of the sieve tools) + Further developed the deprecated notify extension. A dummy for the denotify command exists, meaning that its use does not cause an error anymore. - Fixed a bug in the derivation of the binary path from the script path. A bare filename would yield a path relative to root. - Fixed a bug in the value matching code. The context data now uses a proper pool in stead of the data stack. Bug reported by Jan Sechser. - Fixed assertion fail in the include extension caused by missing initialization upon binary load. This bug surfaces only for stored binaries. Bug reported by Tom Hendrikx. - Fixed include error message for failed :global include. It mentioned the wrong config parameter. - Fixed broken wiki reference in an error message of the plugin about the 'sieve' setting. - Fixed behavior of fileinto when delivering into a namespace prefix. Previous fix used the wrong storage. The release is available as follows: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.10.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.10.tar.gz.sig Have fun testing the new releases and don't hesitate to notify me when there are problems. Please include your configuration, the involved Sieve scripts and an example message in any bug or problem report when possible, so that I can easily reproduce the issue.

Re: [Dovecot] Redirecting mail gives 'mail forwarding loop' to the sender - calling for sieve help
by Andrés Yacopino 15 Aug '09

15 Aug '09

Yes, the configuration seems odd or interesting as you said. The idea behind this is: - Before scripts will be use for filtering spam, when they have SPAM header. Not problem at it. - User scripts will be used for vacation messages. These are created with Squirrelmail and avelsize plugin (user interaction) - After scripts will be used for doing redirections, such as forwarding mail to a blackberry account(not problem at it) or forwarding to another user account (in the same domain, the problem is here). The reason not to put the redirections or forwarding in users scripts is to avoid users deleting redirections and have in one file all the redirections. I also try to use redirections from avelsieve plugin (0.9.9.9) and it works the forwarding but it didn't work the keep command, the mail is forwarded but the user doesn't have a copy of it. I will investigate your advice for envelope or try to use user's scripts. I didn't know about original headers, if this in RFC sieve documents? Thanks Timo and thanks Stephan for the tips. Greetings, Andrés. Andrés Yacopino. Dpto Sistemas AcaSalud

[Dovecot] Very long establishment time for secondary connections
by Jeff Mitchell 14 Aug '09

14 Aug '09

Hello, I'm currently on Dovecot 1.1.17 and I have a user that runs into a problem quite a lot. She's using Thunderbird on a Mac. When she sends mail, Thunderbird is set up to save sent mail to her Sent folder. Often (usually when she has not sent another mail for a long while) when she sends mail, Thunderbird sits there saying "Copying message to Sent folder" for about thirty seconds. My best guess, after looking at dovecot messages in syslog related to her login, is that Thunderbird is using a secondary imap process to do this copying and this connection times out due to inactivity, so that when she sends mail it has to reestablish itself. For some reason this reestablishment seems to take a very long time, even though her initial login/connection when she opens Thunderbird is very fast. I looked for a way to increase the inactivity time in dovecot.conf but didn't see one. I don't know of any other user that has this problem, which makes me suspicious of her client rather than Dovecot. Pretty much everyone is using Thunderbird, although she's the only one using it on a Mac. Is it possible/likely that it takes so long because for some reason Thunderbird on a Mac doesn't notice that the second connection has died and is taking a long time trying to use the first invalid connection before reestablishment? Or is it likely that this is a Dovecot problem and I simply haven't figured out what's going on, yet? All help very much appreciated. Thanks, Jeff

[Dovecot] Upgrade question from 1.1 to 1.2
by Wouter van der Schagt 14 Aug '09

14 Aug '09

Good afternoon, I am considering to upgrade from Dovecot 1.1.18 to 1.2.x and was reading your Wiki regarding any changes and found: "If you were using e.g. mail_location = maildir:/var/mail/%h, just change it to mail_location = maildir:%h and add /var/mail/ prefix to home dirs." I am currently using: "mail_location = maildir:~/Maildir" in combination with vpopmail. Does this need to be changed? or is ~/Maildir considered an absolute directory? Is there anything else I should be aware of ? Sincerely, - Wouter van der Schagt

[Dovecot] Dovecot Proxy
by Michel Bulgado 14 Aug '09

Hello I have installed Dovecot as a POP3 server, IMAP on my internal network, the authentication against Windows Active Directory. I would like to know how to setup a second server dovecot as my proxy server for external users outside the network, in another segment of different IP addresses, or at least define which mailboxes will be stored on another server to be accessible to both servers. I have reviewed the document on the wiki site, but I said that is only possible with mysql authentication, but as I said the road where the messages are stored, it is possible for NFS? Thanks Michel

[Dovecot] QUOTA not appearing in CAPA
by Tim Traver 14 Aug '09

14 Aug '09

Hi, ok, I've compiled it a few times, and made sure all of my settings are correct, but the QUOTA is not appearing in the opening CAPA that comes with the greeting. I have it configured in the dovecot.conf like so: protocol imap { mail_plugins = quota imap_quota } and I can see when turning debugging on that the following is spit out when starting : Starting DovecotILoading modules from directory: /usr/local/lib/dovecot/imap IModule loaded: /usr/local/lib/dovecot/imap/lib10_quota_plugin.so IModule loaded: /usr/local/lib/dovecot/imap/lib11_imap_quota_plugin.so IEffective uid=65534, gid=65534, home=/tmp IQuota root: name= backend=maildir args= IEffective uid=65534, gid=65534, home=/tmp and then I see the following in the dovecot logs : Aug 10 17:35:10 IMAP(xxxxx(a)simplenet.com): Info: Module loaded: /usr/local/lib/dovecot/imap/lib10_quota_plugin.so Aug 10 17:35:10 IMAP(xxxxx(a)simplenet.com): Info: Module loaded: /usr/local/lib/dovecot/imap/lib11_imap_quota_plugin.so when I log into the IMAP port, I get the following greeting : * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN AUTH=LOGIN] Dovecot ready. So it seems there is no QUOTA support for the IMAP server to query for the quota file... can someone help me as to a direction to go here??? The reason I need it is because I believe the web client relies on the QUOTA being in the CAPA in order to show it... Thanks, Tim.

[Dovecot] More effective mailbox fetching over high RTT link
by Andrzej Adam Filip 13 Aug '09

13 Aug '09

Could you offer some suggestion how to fetch mailbox content over high RTT link (with negligible packet loss)? Currently I use IMAP+IDLE *but* it fails to use full available bandwidth due to high RTT and "send command wait for response" nature of POP3 and IMAP4 protocols. -- [pl>en: Andrew] Andrzej Adam Filip : anfi(a)onet.eu Learning without thought is labor lost; thought without learning is perilous. -- Confucius

[Dovecot] sieve: variable extension?
by Lev Serebryakov 13 Aug '09

13 Aug '09

Hello, Dovecot. Does dovecot sieve supports variable extension (rfc5229)? It is very useful for users with large amount of mailing lists, as it allows to write only one rule for all lists (filtering by List-Id). If it is not supported, is here any plans to support it? I can try to implement it, but I don't want to duplicate work, if somebody has this extension in pipeline. -- // Black Lion AKA Lev Serebryakov <lev(a)serebryakov.spb.ru>

[Dovecot] Tilde expansion in ManageSieve for dovecot-1.1.
by Stephen O'Dor 13 Aug '09

13 Aug '09

Greetings all, I'll skip the details of the setup, except to say that it has a non-standard (and non-templateable) home directory path for virtual users. Ran into the following problem when a debian (possibly from backports) packaged dovecot-1.1.2 was upgraded to a dovecot-1.1.13-2~bpo50+1 (definately from backports): sieve-storage: root directory specified by mail data does not exist: ~/Maildir After some analysis, it would appear that ManageSieve (looks like 0.10.4 is included in the debian backports) doesn't do the tilde expansion before doing a stat test to see if the ~/Maildir exists. Here's a quick diff of the change I made to make it work: sodor@madawg:~/tmp/deb-dove/dovecot-1.1-managesieve-0.10.4/src/lib-sievestorage$ diff sieve-storage.c ../../../sieve-storage.c 73c73 < const char *root_dir, *dir, *p, *d; --- > const char *root_dir, *dir, *p, *d, *home; 127a128,133 > /* expand tilde in root so that the stat below works */ > home = getenv("HOME"); > if (home != NULL && *home != '\0') { > root_dir = home_expand_tilde( root_dir, home ); > } > I'm not sure if this was the best way to fix this (or if this is even a bug, I might just have a crazy setup). Thanks, -Steve

[Dovecot] Dovecot proxy server
by michel＠casa.co.cu 13 Aug '09

13 Aug '09

Hello I have installed Dovecot as a POP3 server, IMAP on my internal network, the authentication against Windows Active Directory. I would like to know how to setup a second server dovecot as my proxy server for external users outside the network, in another segment of different IP addresses, or at least define which mailboxes will be stored on another server to be accessible to both servers. I have reviewed the document on the wiki site, but I said that is only possible with mysql authentication, but as I said the road where the messages are stored, it is possible for NFS?

[Dovecot] user_global_* ldap deliver
by Noel Leistad 12 Aug '09

12 Aug '09

Searched archive, but failed to find... :-( "deliver" does not honor user_global_* from dovecot-ldap.conf or userdb static{} also it looks like delivery attempts being made to %n/Maildir/cur ?? one other curious thing, use of ${recipient} in master.cf|deliver command causes the "passdb ldap" lookups to be completely ignored? only checks passdb and ignores userdb compleletely? IF I put noel(at)metc(dot)net into passwd.dovecot using passdb flatfile, auth and delivery seem to work. Thanks for any direction. I lament I couldn't get farther on my own.

[Dovecot] Dovecot Versions and Debian
by Mario Antonio 12 Aug '09

12 Aug '09

If you want to run Dovecot on Debian Lenny for a Production System (with Fast Upgrade System for Security Patches), What would you recommend? Stick to the current port with Dovecot Version 1.0.15 (1:1.0.15-2.3) Use Backports Version 1.1.13 (1:1.1.13-2~bpo50+1) or Use any of the packages from: ---------------------------------------------------------------------------------------------------------------------- Dovecot v1.1 for Debian Testing (binary and source): deb http://xi.rename-it.nl/debian/ testing-auto/dovecot-1.1 main deb-src http://xi.rename-it.nl/debian/ testing-auto/dovecot-1.1 main Dovecot v1.2 for Debian Testing (binary and source): deb http://xi.rename-it.nl/debian/ testing-auto/dovecot-1.2 main deb-src http://xi.rename-it.nl/debian/ testing-auto/dovecot-1.2 main ---------------------------------------------------------------------------------------------------------------------- Do you find any compelling reason for not using version 1.0.15 ? (Besides of ACL limitations ...) Regards, Mario Antonio

[Dovecot] sieve/managesieve and spam filtering
by Charles Sprickman 11 Aug '09

11 Aug '09

Hello all, I've got a test environment setup in preparation for a move from qmail/vpopmail/courier to postfix/padmin/dovecot. I have a number of questions that seem to span multiple pieces of software, and this is one of them... Our policy with spam filtering is that a user should be able to turn it off (ie: not put tagged spam into a spam folder, but deliver to their inbox) if they want to. Currently qmailadmin and a custom squirrelmail plugin give people the option to do this by dumping a .qmail file in their directory that calls a common maildrop script that will deliver spam to the spam folder. It looks like I can emulate this with sieve and something that can speak to Dovecot's managesieve server. Where I'm stuck is that if I want users to be able to do other custom filtering using sieve, how do I go about making sure that my common spam delivery rule does not get clobbered? This really has me a bit stumped. I see there's a global sieverc that can be included, but I need something along the lines of a per-user include that brings in the spam filtering rule that will "stick" until the user explicitly deletes it. Any ideas? Thanks, Charles ___ Charles Sprickman NetEng/SysAdmin Bway.net - New York's Best Internet - www.bway.net spork(a)bway.net - 212.655.9344

[Dovecot] Index cache file problems in Dovecot 1.2.0
by Chris Wakelin 11 Aug '09

11 Aug '09

I've been seeing lots of index cache file errors (using mbox on Solaris 8 sparc 64-bit, but with 32-bit Dovecot) since I switched my account to Dovecot 1.2.0 (we're still on 1.0.15 mostly, but I'm hoping to upgrade to 1.1.17+ this summer, or 1.2.x if it's stable enough). e.g. Error: Corrupted index cache file <path>/.imap/INBOX/dovecot.index.cache: field index too large (47 >= 25) I've tried renaming/removing the .imap/INBOX directory, but the "Corrupted index cache file" errors return within a day or so. This morning, Thunderbird got itself in a mess retrying something that caused multiple core dumps: > Jul 14 08:52:53 dovecot: Error: child 17694 (imap) killed with signal 10 (core dumped) > Jul 14 08:52:54 dovecot: Error: child 17697 (imap) killed with signal 10 (core dumped) > Jul 14 08:52:55 dovecot: Error: child 17700 (imap) killed with signal 10 (core dumped) Here's a backtrace > #0 mail_cache_get_record (cache=0x124e28, offset=289, rec_r=0xffbeeb6c) > at mail-cache-lookup.c:30 > 30 if (rec->size < sizeof(*rec)) { > (gdb) bt > #0 mail_cache_get_record (cache=0x124e28, offset=289, rec_r=0xffbeeb6c) > at mail-cache-lookup.c:30 > #1 0x84e2c in mail_cache_lookup_iter_next_record (ctx=0xffbeeb60) > at mail-cache-lookup.c:186 > #2 0x84f14 in mail_cache_lookup_iter_next (ctx=0xffbeeb60, field_r=0xffbeeb50) > at mail-cache-lookup.c:219 > #3 0x85650 in mail_cache_lookup_headers_real (view=0x128510, dest=0x129728, > seq=11416, field_idxs=0xffbeec74, fields_count=2) > at mail-cache-lookup.c:500 > #4 0x85848 in mail_cache_lookup_headers (view=0x128510, dest=0x129728, > seq=11416, field_idxs=0xffbeec74, fields_count=2) > at mail-cache-lookup.c:555 > #5 0x6ba94 in index_mail_get_raw_headers (mail=0x128f20, > field=0xff142ee8 "Message-ID", value_r=0xffbeecfc) > at index-mail-headers.c:614 > #6 0x6c084 in index_mail_get_first_header (_mail=0x128f20, > field=0xff142ee8 "Message-ID", decode_to_utf8=false, value_r=0xffbeede4) > at index-mail-headers.c:771 > #7 0x7893c in mail_get_first_header (mail=0x128f20, > field=0xff142ee8 "Message-ID", value_r=0xffbeede4) at mail.c:118 > #8 0xff1419a0 in mail_log_add_hdr (mail=0x128f20, str=0x10edc8, > name=0xff142d68 "msgid", header=0xff142ee8 "Message-ID") > at mail-log-plugin.c:277 > #9 0xff141c5c in mail_log_action (dest_trans=0x128f20, mail=0x128f20, > event=MAIL_LOG_EVENT_DELETE, data=0x0) at mail-log-plugin.c:318 > #10 0xff141e5c in mail_log_mail_update_flags (_mail=0x128f20, > modify_type=MODIFY_ADD, flags=12) at mail-log-plugin.c:376 > #11 0x78af8 in mail_update_flags (mail=0x128f20, modify_type=MODIFY_ADD, > flags=12) at mail.c:184 > #12 0x2ab3c in cmd_store (cmd=0x11bec8) at cmd-store.c:192 > #13 0x2b5f8 in cmd_uid (cmd=0x11bec8) at cmd-uid.c:27 > #14 0x2ccc4 in client_command_input (cmd=0x11bec8) at client.c:611 > #15 0x2cb68 in client_command_input (cmd=0x11bec8) at client.c:660 > #16 0x2cd4c in client_handle_next_command (client=0x11bc40, > remove_io_r=0xffbef23f) at client.c:701 > #17 0x2ce40 in client_handle_input (client=0x11bc40) at client.c:713 > #18 0x2cf78 in client_input (client=0x11bc40) at client.c:752 > #19 0xc6c04 in io_loop_handler_run (ioloop=0x1186d8) at ioloop-poll.c:203 > #20 0xc63f4 in io_loop_run (ioloop=0x1186d8) at ioloop.c:338 > #21 0x369f4 in main (argc=1107968, argv=0xffbef484, envp=0xffbef494) > at main.c:323 I didn't have these problems with 1.1.x.

[Dovecot] Problems with Dovecot 1.2.3 + IMAP (SSL) + iPhone OS 3.0
by Sascha Scandella 11 Aug '09

11 Aug '09

Hello Has anyone else problems with Dovecot 1.2.3? For clients such as Thunderbird, Outlook 2007 everything works perfect. When I use an iPhone the child process is killed: Aug 11 08:08:44 imap-login: Info: Login: user=<username>, method=PLAIN,rip=1.2.3.4, lip=4.3.2.1, TLS Aug 11 08:08:44 dovecot: Error: child 5382 (imap) killed with signal 11 (core dumps disabled) Currently I have downgraded again to the working 1.2. I wonder if this problem is known or anyone is looking for it.

[Dovecot] RFC: Storing indexes in a (remote) database to increase dovecot scalability
by Mark Zealey 10 Aug '09

10 Aug '09

Hi all, This is just an idea I had over the weekend; I was wondering if instead of storing the indexes/caches on disk, it would be possible to have an option to store them in a remote database (eg mysql). There are several issues that we currently have with scaling dovecot, and I think that if it could store indexes in an external database we could alleviate most of these issues. In no particular order: 1) One major issue we have with dovecot is the number of iops it requires to keep its files in sync on our big disk arrays. If this were a mysql database, we'd have better ways of keeping these in sync, for example switching the speed at which it flushes the updates to disk, growth using partitioning/sharding, read-only slave instances etc, specific ssd storage for indexes/caches. I know that we could create a separate ssd disk array and export that over nfs too, but see issue (2) below. If indexes were stored in a mysql database we could choose to have a different reliability for the indexes (ie if the database server crashes we have 1 second of index changes lost, whereas for the email itself we can ensure it is always kept in sync on our other disk arrays). 2) nfs locking issues. No matter how hard we try, we always find there are some issues with concurrency over nfs. It really doesn't seem designed to handle these issues very well. I've not tried with nfsv4 and I believe there are some improvements there, but at the same time nfs wasn't really designed to store databases and have heavy concurrency. A proper database server (eg mysql, postgres) on the other hand thrives in this type of environment, especially when coupled with a transactional storage backend such as innodb which includes support for deadlock handling etc. 3) As we store all of our mail systems over nfs, effectively each export is a single-threaded connection to the server. No matter how fast the central nfs server you can realistically not go above 10k nfs ops/sec on the fastest of local networks due to latency issues. With mysql you could have multiple parallel connections to the central database store (1 per process?) which would mean more nfs ops available for actually serving the files. 4) Caching. Much more tuneable on a database server than in a filesystem. Eg in mysql there are loads of options to tune the various innodb/query/key caches, on nfs there are very few even on advanced netapps etc I know some of you store all your indexes on a single server locally & then store the emails on a remote central filestore. Whilst this is a good idea, it doesn't scale very well in that if the one server fails then everything has to be reindexed as clients login which causes incredible load as dovecot has to re-read most of the messages (in pop3 mode at least) in order to work out size counts etc. In my experience this reindexing would take out our email system for the best part of a day. I'm sure we could set something up with drbd mirroring or a central san array with ssd's for the index data, but this intrinsically does not scale with as much ease as a replicating database cluster could. There are also failover issues which can be very easily solved with a database system (eg mysql with an active/passive dual-master setup). Also, I know that most of these points refer to nfs; and I know that there are alternative methods (eg san + gfs or some other scalable filesystem) however most of these are relatively new technologies whereas nfs is pretty much the standard for remote file storage; certainly I'd consider it a lot more reliable when compared to the likes of gfs or lustre. Your typical large scale mail setup would be over nfs and this is the sort of environment that I've run into these scaling issues in. I've heard that gfs also doesn't work very well with 'hot spots' which indexes tend to be, although I've no first hand experience of this. So, although this post only really mentions nfs & mysql (the two technologies that I'm most familiar with) I think this is a much more general problem so I'm not advocating the use of either technology apart from them being most people's first choices for ease of use. What I'm really proposing is a way to separate the two different types of data that dovecot uses. Indexes&caches contain small frequent transactions; and whilst these are relatively important, dropping the past few seconds of these transactions doesn't seriously matter. On the other hand emails are larger, infrequently changed & it's important they are kept fully in sync - if we accept a message it should be guaranteed that we don't loose it. At the end of the day it seems to me that a filesystem is the ideal place to store emails, whereas a database server would be the ideal place to store indexes/caches. Obviously for speed of setup, simply storing everything on a filesystem is easy so I'm not suggesting that we abandon this route, but for truly large infrastructures I think being able to use a database system would have significant advantages in each of these four areas. Any thoughts?

Hi, I´m using dovecot at our storages, accounts is distributed among many storages (not entire domain), all of them with compression (when message > 30Kb), nightly crontab script. Even though compression and many storages, we always have problems with disk space and need to migrate accounts. Have you ever implemented any archive solution working with dovecot ?

[Dovecot] Mail not begin proccessed
by Andre Labuschagne 10 Aug '09

10 Aug '09

Good day all, [Dovecot version 1.2.1] I've set up postfix and dovecot on Centos. I have a problem with the mail, it is begin received but not "processed" by dovecot. I've looked in the maillog file and found two problems; the first is that private/dovecot directory (I think it should be a directory) did not exist and the second problem is "mail transport unavailable". I've create a directory called /var/spool/postfix/private/dovecot but I get the following error in the log file: Connection refused (Is this an ownership issue? I've made the owner postfix) As for the second problem, I've spend the most of the past 3 days googling the error and found very little "useful" information. Do I need to supply more info? Best regards, Andre

[Dovecot] Released Sieve v0.1.11 and ManageSieve v0.11.8 for Dovecot v1.2.3
by Stephan Bosch 10 Aug '09

10 Aug '09

Hello Dovecot users, Apart from unfinished development of the date extension, this is a set of bug-fix releases. A few portability issues were found, a few stupidities were fixed and the ManageSieve proxy now also works with TLS. Most notably, the include extension had an issue regarding the expansion of $HOME in the personal include path. I've built a project site at: http://pigeonhole.dovecot.org Changelog Sieve v0.1.11: + Built skeleton implementation for the date extension (RFC5260). It compiles, but it does not do anything useful yet. Therefore, it is not part of the default compilation. - Fixed ARM portability issues caused by char type not being signed on that platform. Reading optional operands from a binary would fail for action side effects. Also, an accidental mixup of an int return type with bool caused the interpreter to continue on ARM even though an error occured. - Removed direct stdint.h includes to prevent portability issues. - Fixed segfault bug in the handling of script open failures. - Include: improved user error messages and system log messages. - Fixed copy-paste mixup between sieve_after and sieve_before settings in the LDA Sieve plugin. If only a sieve_after script was active, nothing would have been executed. Patch by Mike Abbott. - Include: fixed a bug in HOME substitution in the sieve_dir path. Surfaced in ManageSieve. Changelog ManageSieve v0.11.8: - Fixed TLS support for proxying ManageSieve. The protocol state machine was incorrect. Also added a check that disables ssl when 'starttls' is not enabled for the user. This produces a proper warning in the log file. There is no such thing as a managesieveS protocol which has SSL from the start. The releases are available as follows: Sieve: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.11.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.11.tar.gz.sig ManageSieve (package + patch): http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.8.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.8.tar.gz.s… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.3-managesieve-0.11.8.diff.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.3-managesieve-0.11.8.diff.g… Have fun testing the new releases and don't hesitate to notify me when there are problems.

[Dovecot] virtual plugin and ACL
by Nikita Koshikov 10 Aug '09

10 Aug '09

Hello list, We are using virtual plugin for to provide users two additional folders: Company/all - it contains all messages in user's mailbox Company/favorites - here is flagged messages. Here is namespace part of config file: namespace private { prefix = Company/ separator = / location = virtual:/var/mail/virtual:INDEX=MEMORY:LAYOUT=maildir++ subscriptions = no } Everything works fine, but problem arises when someone rename or delete virtual mailbox.

[Dovecot] how secure is Dovecot when exposed to the Internet?
by Florin Andrei 10 Aug '09

10 Aug '09

$ dovecot -n # 1.1.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.28-11-server x86_64 Ubuntu 9.04 protocols: imap imaps managesieve I need to make an IMAP (actually imaps) server available over the Internet. Unfortunately, VPN is not available (not all clients support VPN), so I will have to expose the imaps port to the Internet. My question is: how reliable is Dovecot in such a setup? I am not talking about encryption (protecting the traffic between server and client). I am talking about having the daemon exposed to anything coming in from the Internet, buffer overflows and stuff like that. What's the security history of this software in situations like this? -- Florin Andrei http://florin.myip.org/

[Dovecot] Wiki entry for expire plugin, PostgreSQL trigger needs update
by Stefan Förster 09 Aug '09

09 Aug '09

The wiki entry at http://wiki.dovecot.org/Plugins/Expire needs an update for Dovecot 1.2 and PostgreSQL: -- v1.2+: CREATE OR REPLACE FUNCTION merge_expires() RETURNS TRIGGER AS $$ BEGIN IF exists(SELECT 1 FROM expires WHERE username = NEW.username AND mailbox = NEW.mailbox) THEN UPDATE expires SET expire_stamp = NEW.expire_stamp WHERE username = NEW.username AND mailbox = NEW.mailbox; RETURN NULL; ELSE RETURN NEW; END IF; END; $$ LANGUAGE plpgsql; CREATE TRIGGER mergeexpires BEFORE INSERT ON expires FOR EACH ROW EXECUTE PROCEDURE merge_expires(); At least that's what I think after looking at the code: iter = dict_iterate_init(dict, DICT_EXPIRE_PREFIX, DICT_ITERATE_FLAG_RECURSE | DICT_ITERATE_FLAG_SORT_BY_VALUE); /* We'll get the oldest values (timestamps) first */ while (dict_iterate(iter, &key, &value) > 0) { /* key = DICT_EXPIRE_PREFIX<user>/<mailbox> */ userp = key + strlen(DICT_EXPIRE_PREFIX); [...] T_BEGIN { username = t_strdup_until(userp, p); If this code does somehow iterate usernames which are not present in the dict, I apologize.

[Dovecot] User Auth
by Richard Harwood 09 Aug '09

09 Aug '09

Hello all, I am new to the mailing list and I'm in the process of setting up a LAMP + mail server. I have configured my MTA (Postfix) to deliver messages to: /var/spool/mail/vhosts/domain.tld/name I have configured Dovecot as follows: -- # 1.2.2: /usr/local/etc/dovecot.conf protocols: imap imaps pop3 ssl: no disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/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 mail_privileged_group: mail mail_location: mbox:/var/spool/mail/vhosts/%d:INBOX=/var/spool/mail/vhosts/%d/%n mail_debug: 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_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 lda: postmaster_address: postmaster(a)example.com auth default: debug: yes passdb: driver: passwd-file args: /etc/passwd.dovecot userdb: driver: passwd -- Password excepted, my passwd.dovecot file containing a single virtual user looks like: richard:{plain}password:504:505::/home/vmail The uid/gid is the same as used by Postfix (a dedicated vmail user/group). That user/group owns the mbox I am trying to manipulate in this example. When I attempt to login via telnet on port 110 I get the error: +OK Dovecot ready. user richard(a)richardaharwood.com +OK pass password -ERR Authentication failed. It seems to dislike the fact I specify the domain as part of the login username. If I repeat and login as: user richard - I am authenticated, however I get the error: -ERR [IN-USE] Couldn't open INBOX: Internal error occurred. Refer to server log for more information.

I also notice the effective uid/gid is not that specified in the passwd file? The uid/gid appears to be that of my own ssh account which is not connected to the mail account that I wish to simply access as a virtual user. Would anyone be kind enough to point me in the right direction? In a nutshell, where am I going wrong with my authentication? This is a basic setup for the time being, until I get my head around it, but any pointers would be really appreciated. Have spent quite a few hours but I don't feel much closer to getting to the bottom of it! :) Many thanks, Richard

[Dovecot] multiple auth-client sockets
by LEVAI Daniel 09 Aug '09

09 Aug '09

Hi! I'm gonna need to use dovecot's auth-client socket in an authentication program. Now the auth-client socket is only used by my MTA, which is postfix. Because postfix's smtpd process (which uses the auth-client socket) runs chrooted under postfix's spool directory, I must create the auth-client socket under that spool directory. However, to reach that socket from another chrooted program is impossible. Can I create multiple instances of auth-client sockets? I tried to define another client {} stanza in socket listen {} in dovecot.conf, but only the last client socket got created. I need only a true or false response from dovecot regarding the authentication, and I thought that this is exactly what auth-client socket will do. However, if I can not reach it, is there any alternative to this? What's up with the auth-master or auth-worker sockets? Are they capable of respond to an auth request too? btw, I'm running dovecot-1.2.3 Thanks!

Hi, I'm one step away from replacing a 7 years old qmail/uw-imapd setup with some state of the art soft- and hardware. We got migration scripts and test almost done - just one thing that keeps failing: The autocreate plugin is supposed to subscribe new users to different mailboxes, one of them being in namespace "Public." - this subscription to "Public.announcements" fails.

[Dovecot] Creating a "default" domain
by Charles Sprickman 09 Aug '09

09 Aug '09

Hello, I'm setting up a test server to work through the issues involved in bringing a bunch of vpopmail/qmail/courier users into a postfix/dovecot server. So far I'm seeing lots of info to aid in the transition. One thing I'm lost on is that since Dovecot is providing all the auth mechanisms rather than vpopmail, I'm not sure how to emulate a particular vpopmail behavior we rely on. Vpopmail allows for the concept of a "default" domain for authentication. So if I have a bunch of domains, and one is "example.com", users in that domain can login with only the username part of their id (ie: "john") rather than supplying the domain (ie: "john(a)example.com"). I need to continue to offer this unless I want to walk a few hundred users through reconfiguring their mail clients. :) Any pointers?

[Dovecot] convert config from 1.1.2_1 to 1.1.16

Hi, Im tryin to follow a guide, telling me howto setup freebsd with postfix and dovecot. The text in bold (first section), is what the guide says, and the text that follows is what the /usr/local/etc/dovecot.conf files says. Can you please help me on how to convert from the 1.1.2_1 setup to the correct configuration for the 1.1.16? / Thank you very much. *socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } * socket listen { master { # Master socket provides access to userdb information. It's typically # used to give Dovecot's local delivery agent access to userdb so it # can find mailbox locations. path = /var/spool/postfix/private/auth mode = 0600 # Default user/group is the one who started dovecot-auth (root) #user = #group = } client { # The client socket is generally safe to export to everyone. Typical use # is to export it to your SMTP server so it can do SMTP AUTH lookups # using it. path = /var/run/dovecot/auth-client mode = 0660 }

[Dovecot] All mail in mbox disappears when using Outlook
by Frank Leonhardt 08 Aug '09

08 Aug '09

I thought I was imaging it but... I have a friend (honestly) that likes to clear his inbox every month by copying older into a folder (e.g. June-2009). Every month he complains that all the mail in the new folder has disappeared. This has happened three times now, and he's sort-of-right. I now believe it's a bug rather than him. The setup is Dovecot 1.1.3 on FreeBSD 7.0 and the client is Outlook 2003 SP3 (using IMAP). What you end up with is a folder called June-2009 with no messages visible. Outlook reckons it's completely empty - size 0. I don't know how he gets to this point, but it can't be anything that bizarre - just copying messages. It's happened three months in a row. However, he can't see the contents and I can't see the contents using Outlook. Strangely, Eudora and Squirrel have no problem. Corrupt mbox file? Probably not. If you copy the problem one, the copy works fine. The really weird thing is that if you rename the problem file (using mv) it STILL DOESN'T work. I've considered the possibility that it's got a bad lock on it, but if so, how come Squirrel and Eudora have no problem? I've searched as far as I can for any known problems using Outlook. What next?

[Dovecot] hoping someone has a suggestion
by P.A 07 Aug '09

07 Aug '09

Hi using dovecot 1.0.10 with pop/imap, using maildir, with 2000+ users mostly using pop but many using imap. Once in a great while I have problems with dovecot pop timing out. If I telnet to port 110 it just takes forever to come up or it doesn't at all, the samething happens on the imap port although 110 is always worst. At 1st when troubleshooting I was not sure what was causing the situation and when I ran out of options I stopped postfix. When I did this dovecot immediately started working again, that is port 110/143 came up fast and all the user logins were fast again. When I restarted postfix after a minute or so dovecot became slow again. While observing this situation I notice that postfix had most of the connections about 300+ in established state, while dovecot was using around 150 connections. After adjusting some of the parameters on postfix and shutting it down multiple times, suddenly everything worked but this time postfix was reporting over 3000 connections mostly in TIME_WAIT state which is normal for us. My question is what do you guys think is happening here, what is the relationship between dovecot/postfix that would cause this to happen. I'm just looking for some suggestions in case this happens again. # 1.0.10: /usr/local/etc/dovecot.conf protocols: imap pop3 ssl_disable: yes disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/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: D-V1 NP09 ready. login_process_size: 384 login_processes_count: 55 login_max_processes_count: 450 mail_location: maildir:/home/%1u/%u/Maildir maildir_copy_with_hardlinks: yes maildir_copy_preserve_filename: 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_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 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: count: 4 passdb: driver: shadow userdb: driver: passwd

[Dovecot] Bug - dovecot-auth hangs in ldap query. 1.1.16 (also in 1.2.2)
by Marek Miska 07 Aug '09

07 Aug '09

dovecot-auth hangs when many (>128) LDAP queries are submited simultaneously. (for example via pop3 benchmarking tool). Bug is in src/auth/db-ldap.c:db_ldap_request_queue_next if (queue_size > DB_LDAP_MAX_PENDING_REQUESTS) { /* wait until server has replied to some requests */ return FALSE; } (queue_size is total queue size, not only queries sent to LDAP server.) I think this condition should be: if (conn->pending_count >= DB_LDAP_MAX_PENDING_REQUESTS) {

[Dovecot] Trying to get dovecot and squirrelmail talking
by Neil Bird 07 Aug '09

07 Aug '09

I have been using dovecot+squirrelmail with no problems on my Fedora box (currently at F10). I've been using a simple mail location string along the lines of 'mbox:~/usr/mail/%u:INBOX=mbox:/var/spool/mail/%u' (sorry, that's off the top of my head, I can't get into my box from here at the moment). Essentially: standard mbox inbox in /var/spool/mail/[user], plus mbox files under ~/usr/mail. These latter are for remote access to archived Thunderbird files, which are [currently] mbox format. This works fine. However, I've had some slight issues elsewhere which I feel would be eased or solved by making my INBOX use maildir format, and keeping mails I want to remote-access more often in the top level maildir there (instead of always having to dip into the TB mboxes). To that end, I tried setting up: # want to be able to add sibling and child folders here namespace private { separator = / prefix = location = /var/spool/mail/%u inbox = yes hidden = no list = yes } # And the legacy mbox files go here under 'local' namespace private { separator = / prefix = local/ location = mbox:~/usr/mail hidden = no list = yes } (with appropriate an procmail change for maildir delivery) Now, this pretty much worked the way I wanted. However, afterwards, trying to connect from squirrelmail I had it say that there were no [IMAP] folders to subscribe to, including the INBOX. I couldn't se any errors, either in /var/log/maillog or http's logs. Have I got something wrong? Am I trying to do something that's doomed to failure? -- [neil@fnx ~]# rm -f .signature [neil@fnx ~]# ls -l .signature ls: .signature: No such file or directory [neil@fnx ~]# exit

[Dovecot] Dovecot deliver uidlist issues
by Mark Zealey 07 Aug '09

07 Aug '09

Hi all, Lets say I have a maildir which doesn't contain any dovecot files but has some emails lying around in it. If I add a message to this mailbox using deliver, dovecot creates the uidlist file with a single entry (the message that was just delivered). When I then log in to the mailbox, all the other messages are added into the uidlist file in the normal order (directory list order I believe). Then, the mailbox is in a situation where anything that was delivered into the mailbox before the user logs in is at the very top of a uidlist. Unfortunately many webmail clients seem to order the mailbox by reverse uidl, so we get the situation where people log into webmail (we use @mail) after their mailboxes have been migrated to dovecot and any messages delivered between the time of migration and the time of login are put to the very end of the list. This could presumably be fixed by ordering the mailbox according to date but certainly @mail doesn't really do this very well. I've only tested this on v1.1 (1.1.17 from atrpms), but I didn't see anything in the changelog to indicate that this deliver behaviour has changed in v1.2. Perhaps there should be a deliver option to recreate the uidlist file by doing a full scan if it doesn't exist (as a login via pop/imap would do), although I'm not sure why this shouldn't be the default? (apart from deliever potentially causing a high amount of io). My current work-around is to use postlogin to remove the uidlist file when someone logs in to the mailbox for the first time which then forces it to be created in the correct order; but this is a very messy solution.

[Dovecot] connect to IMAP
by jolan D 07 Aug '09

07 Aug '09

hi, I am trying to get a webbased IMAP mail module to work. http://nocc.sourceforge.net/ But it seems it doesn't connect to it. When i try to login it says: "login is not allowed for connection" i guess it has to do with the settings of the conf file. I have dovecot installed on Centos and installed it with yum. All (basic)settings are usually set correctly during install. After trying hard still no login. So i am hoping you guys can help me out.

[Dovecot] sieve rules processing
by Nikita Koshikov 06 Aug '09

06 Aug '09

Hello list, My question: is sieve support some kind of "continue" action, to explicit tell server processing rules below current one(if current has triged)? Situation: I have few rules, which fileinto's to different directories. All is working fine, but if I want redirect all my mail for some period of time to another mailbox, I'm adding rule like this, to be processing first. if anyof (true) { redirect "koshikov(a)gmail.com"; keep; } Mail redirecting, but keep state store messages to INBOX. All I want - to process other rules, which will move message to the right imap directory. This situation also happens with vacation sieve-action. In sieve rfc I didn't find any workaround to that actions. Maybe someone know how to make sieve working in described way?

[Dovecot] deliver is curious
by Sven Strickroth 06 Aug '09

06 Aug '09

Hi, Im' using deliver with postfix (mailbox_command = /usr/lib/dovecot/deliver -n -m "$EXTENSION"). In dovecot.conf I've set mail_location to maildir:/var/spool/imap/users/%u/Maildir It works, but not for ONE "special" email. If I send mail to e.g. th(a)trg-oha.de it gets correctly delivered (see noerror.txt), but I have one mail with an attachment (i cannot provide it because of privacy reasons) where i get the attached error. How comes that deliver doesn't use the mail_location but the real home-directory (from ldap, it doesn't exist on the mailserver) of that user in this case? -- Best regards, Sven mailto:sven@clamav.net ClamAV, a GPL anti-virus toolkit http://www.clamav.net Aug 3 00:57:40 mailsrv postfix/qmgr[15624]: 4C8582024C: from=<kt(a)gmx.de>, size=1436493, nrcpt=1 (queue active) Aug 3 00:57:40 mailsrv dovecot: deliver(th): Home dir not found: /home/daten/user/lehrer/th Aug 3 00:57:40 mailsrv dovecot: deliver(th): Namespace: type=private, prefix=, sep=., inbox=yes, hidden=no, list=yes, subscriptions=yes Aug 3 00:57:40 mailsrv dovecot: deliver(th): maildir: data=/var/spool/imap/users/th/Maildir Aug 3 00:57:40 mailsrv dovecot: deliver(th): maildir++: root=/var/spool/imap/users/th/Maildir, index=, control=, inbox=/var/spool/imap/users/th/Maildir Aug 3 00:57:40 mailsrv dovecot: deliver(th): Namespace: type=shared, prefix=users.%n., sep=., inbox=no, hidden=no, list=(null), subscriptions=no Aug 3 00:57:40 mailsrv dovecot: deliver(th): shared: root=, index=, control=, inbox= Aug 3 00:57:40 mailsrv dovecot: deliver(th): Namespace: type=public, prefix=shared., sep=., inbox=no, hidden=no, list=(null), subscriptions=no Aug 3 00:57:40 mailsrv dovecot: deliver(th): maildir: data=/var/spool/imap/shared Aug 3 00:57:40 mailsrv dovecot: deliver(th): maildir++: root=/var/spool/imap/shared, index=, control=, inbox= Aug 3 00:57:40 mailsrv dovecot: deliver(th): Namespace : Using permissions from /var/spool/imap/users/th/Maildir: mode=0700 gid=-1 Aug 3 00:57:40 mailsrv dovecot: deliver(th): mkdir_parents_chown(/home/daten/user/lehrer/th) failed: Permission denied (euid=2684(th) egid=12(mail) missing +w perm: /home) Aug 3 00:57:40 mailsrv dovecot: deliver(th): copy: i_stream_read() failed: Permission denied Aug 3 00:57:40 mailsrv dovecot: deliver(th): msgid=<F915DEB780CD459A93FA6A3E9B4564BA@EeeTh>: save failed to INBOX: Internal error occurred.

[Dovecot] Deliver LDA versus vdelivermail
by Wouter van der Schagt 05 Aug '09

05 Aug '09

Good morning all, I have a question. Due to my interest in the Sieve plug-in. I'm considering to change the LDA on my production servers from 'vdelivermail' from vpopmail to 'deliver' from Dovecot. However I'm not sure how to go about doing this or whether there are any conversion issues that I should be aware of. Currently my /var/qmail/control/defaultdelivery is set to "./Maildir/". I am assuming I have to set that to: "|/var/qmail/bin/preline -f /usr/local/libexec/dovecot/deliver -d $EXT@$USER" Does it also mean I have to recreate all .qmail and .qmail-default files? Am I missing anything else? Does anybody have any experience in changing LDA on production servers? Sincerely, - Wouter van der Schagt

[Dovecot] sieve not working with Postfix and maildir
by Florin Andrei 03 Aug '09

03 Aug '09

I am moving away from Cyrus, I'm trying to migrate to Dovecot. I am trying to get Sieve working with Dovecot and Postfix and it just won't work. Postfix is able to delived new messages to the "new" subfolder of the inbox structure. After I run Thunderbird, the new message gets moved to "cur" and it shows up in my inbox. So far so good. But now I'm trying to add Sieve. I turned on managesieve, installed Avelsieve in Squirrelmail, and did some tests. No matter what, the message stays in the inbox, it does not move to the designated folder: Postfix throws it in "new", it gets moved to "cur" after accessing my email with Thunderbird, and that's it.

With Cyrus and Postfix, the filters worked like a charm, no problems at all, but it had its own issues (too complicated to manage for a small site). Dovecot seems more reasonable, but I can't get Sieve to work. :-( -- Florin Andrei http://florin.myip.org/

[Dovecot] Linefeeds in mailbox names

Wonder if I should just disallow creating mailboxes whose name contains CR or LF characters? Wonder how many peoples' scripts/tools already would break if a user created such mailbox names.. :)

[Dovecot] v1.2.3 release candidate
by Timo Sirainen 03 Aug '09

03 Aug '09

http://dovecot.org/tmp/dovecot-1.2.3.rc.tar.gz I thought about doing v1.2.3 release immediately, but I think I'll wait about 10-24h first. So until then, testing this RC is appreciated and hopefully we'll have a good release this time. :) + Allow namespace prefix to be opened as mailbox, if a mailbox already exists in the root dir. - Maildir: dovecot-uidlist was being recreated every time a mailbox was accessed, even if nothing changed. - listescape plugin was somewhat broken - Compiling fixes for non-Linux/BSDs

[Dovecot] Performance problem with STATUS after upgrade (1.0.15 -> 1.2.2)
by Stefan Förster 03 Aug '09

03 Aug '09

Hello list, after upgrading dovecot from 1.0.15 to 1.2.2 (and carefully reading through the upgrading notes in the wiki), I got sieve, quota and fts up and running, but I'm now suffering some kind of performance problem with the STATUS command. Symptoms: Reading mail on the IMAP server itself with "mutt", no TLS/SSL, connected through loopback interface. Whenever I idle a bit and then hit any key thereafter, for example to change into another mailbox, mutt will send a number of "STATUS" commands: # T 127.0.0.1:53604 -> 127.0.0.1:143 [AP] DONE..a0070 STATUS "postfix-buch" (UIDNEXT UIDVALIDITY UNSEEN RECENT)..a0071 STATUS "postfix-users" (UIDNEXT UIDVALIDITY UNSEEN RECENT)..a0072 STATUS "Trash" (UIDNEXT UIDVALIDITY UNSEEN RECENT)..a0073 STATUS "Sent" (UIDNEXT UIDVALID ITY UNSEEN RECENT)..a0074 STATUS "mailman-users" (UIDNEXT UIDVALIDITY UNSEEN RECENT)..a0075 STATUS "mailman-developers" (UIDNEXT UIDVALIDITY UNSEEN RECENT)..a0076 STATUS "de-postfix-users" (UIDNEXT UIDVALIDITY UNSEEN RECENT)..a0077 STATUS "amavis-users" (UIDNEXT UIDVALIDITY UNSEEN RECENT)..a0078 STATUS "spam" (UIDNEXT UIDVALIDITY UNSEEN RECENT)..a0079 STATUS "localreports" (UIDNEXT UIDVALIDITY UNSEEN RECENT)..a0080 STATUS "Drafts" (UIDNEXT UIDVALIDITY UNSEEN R ECENT)..a0081 STATUS "exim-users" (UIDNEXT UIDVALIDITY UNSEEN RECENT).. # (The whole conversation is available as: http://www.incertum.net/~cite/dovecot-snoop.log) Those commands take almost one(!) second to complete. I've used strace to capture what happens and made the results available at http://www.incertum.net/~cite/imap.log. With 1.0.15, I never noticed this kind of delay, and reading mail feels really sluggish at the moment. Is there any way to improve performance?
