[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. Anyone else experienced this problem ? -- Stuart Gall ---------------------------------------------- All of your mail are belong to us

[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

Hello, i sync with imapsync from an archiopteryx-server to an dovecot-server, for testing until now. The dovecot is inside an VM. storage for mail is on an nfs-share, indexes are local. What i now see, is, on large folder( 58000 messages and more) the load on the imap-process is very high, and slowdown the transferprocess. Is there something, I can do.

[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

[Dovecot] changing location of index files
by suzuki 09 Sep '09

Hello, I think changing index files location of mail_location setting to reduce disk I/O. by adding "INDEX=/var/index/%d/%1n/%n" to mail_location like below, mail_location = maildir:~/Maildir:INDEX=/var/index/%d/%1n/%n Will this change cause any problems or data loss to existing pop3 users?

Re: [Dovecot] FTS Plugin design
by rui.carneiro＠portugalmail.net 09 Sep '09

09 Sep '09

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

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] IMAP Directory Issues (brand new install)

Hi, I just installed dovecot 1.1.11 and am having some issues. Mail appears to be delivered to the Maildirs just fine, but when a client (Thunderbird) tries to retrieve them I get this: dovecot: IMAP(info(a)aedisit.com): maildir_file_do(/var/mail/ > aedisit.com/info/cur/1251566335.V14I27a91M380600.kim) Filename keeps > changing After turning on mail debug mode, I get this: Aug 29 13:41:48 kim dovecot: IMAP(vollmarj(a)aedisit.com): maildir: > data=/var/mail/ > aedisit.com/vollmarj:INDEX=/var/dovecot/indexes/aedisit.com/vollmarj Aug 29 13:41:48 kim dovecot: IMAP(vollmarj(a)aedisit.com): maildir++: > root=/var/mail/aedisit.com/vollmarj, index=/var/dovecot/indexes/ > aedisit.com/vollmarj, control=, inbox=/var/mail/aedisit.com/vollmarj Here is my dovecot -n output: # 1.1.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.28-15-server x86_64 Ubuntu 9.04 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login mail_privileged_group: mail mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 auth default: passdb: driver: pam userdb: driver: passwd

[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 --

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. Best regards John Doe"; Incoming email looks like: Sep 5 15:45:01 ubuntu deliver(test3(a)gewaltphantasien.de): auth input: maildir=gewaltphantasien.de/test3 Sep 5 15:45:01 ubuntu deliver(test3(a)gewaltphantasien.de): auth input: uid=1001 Sep 5 15:45:01 ubuntu deliver(test3(a)gewaltphantasien.de): auth input: gid=1001 Sep 5 15:45:01 ubuntu deliver(test3(a)gewaltphantasien.de): Home dir not found: Sep 5 15:45:01 ubuntu deliver(test3(a)gewaltphantasien.de): maildir: data=/var/mails/gewaltphantasien.de/test3 Sep 5 15:45:01 ubuntu deliver(test3(a)gewaltphantasien.de): maildir++: root=/var/mails/gewaltphantasien.de/test3, index=, control=, inbox=/var/mails/gewaltphantasien.de/test3 !!!!

It seems deliver is taking up a lot of cpu. Is there a way to throttle just the delivery command?

[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

Hi, I´m using a multi-storage architecture in my email environment and maildrop as deliver command at mta. But to this deliver the mx servers mount nfs partitions - we need to use maildrop because many patches we inserted. How can I insert a piece of code at maildrop allowing it to update the dovecot indexes (which lib and/or function from dovecot I need to use ?) 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] Sieve segfault on sieve-before scripts
by Max Ivanov 03 Sep '09

03 Sep '09

I use dovecot 1.2.4 release with sieve 0.1.12 If I setup sieve-before script and latest script contains "keep" at the very end and no personal scripts found then segfault take place. here is part of exim log: 2009-09-01 18:43:06 1MiUZA-0005V9-IB ** ivanov_maxim(a)domain.my <admin(a)domain.my> R=localuser T=local_delivery: Child process of local_delivery transport (running command "/usr/libexec/dovecot/deliver -d $local_part") was terminated by signal 11 (Segmentation fault) Once I remove "keep" from end of latest sieve-before script, everything goes fine. Here is latest global sieve script: # cat /etc/dovecot1.2/sieve-before.d/020-SENT-STORE.sieve require ["imap4flags"]; if header :contains "X-Set-Seen" ["Yes", "YES", "1"] { setflag "\\Seen"; } #keep;

[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? Should I attach compile configs? #/usr/local/sbin/dovecot -n # 1.2.3: /usr/local/etc/dovecot.conf # OS: SunOS 5.11 i86pc base_dir: /opt/csw/dovecot/ protocols: imap imaps pop3s pop3 ssl_cert_file: /etc/ssl/mail.rapid.pem ssl_key_file: /etc/ssl/mail.rapid.key ssl_key_password: password disable_plaintext_auth: no shutdown_clients: no login_dir: /opt/csw/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: VFEmail.net ready. login_process_per_connection: no login_process_size: 256 login_processes_count: 6 login_max_processes_count: 512 login_max_connections: 384 mail_max_userip_connections: 25 verbose_proctitle: yes first_valid_uid: 89 last_valid_uid: 89 first_valid_gid: 89 last_valid_gid: 89 mail_privileged_group: mail fsync_disable: yes mail_executable(default): /usr/local/libexec/dovecot/rawlog /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/rawlog /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/rawlog /usr/local/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 imap_client_workarounds(default): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(pop3): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh namespace: type: private separator: . prefix: INBOX. inbox: yes list: yes subscriptions: yes lda: postmaster_address: postmaster(a)vfemail.net mail_plugin_dir: /usr/local/lib/dovecot/lda sendmail_path: /var/qmail/bin/sendmail auth_socket_path: /opt/csw/dovecot/auth-master auth default: mechanisms: plain login digest-md5 cram-md5 user: vpopmail username_translation: %@ passdb: driver: vpopmail userdb: driver: passwd userdb: driver: vpopmail socket: type: listen master: path: /opt/csw/dovecot/auth-master mode: 384 user: vpopmail plugin: quota: maildir

[Dovecot] rawlog adjustment
by Thomas G. Lau 02 Sep '09

02 Sep '09

Dear All, We would like to use rawlog to make sure when does user delete email, can we filter particular command that user sent to dovecot server instead of log the whole email content as well? how would you all provide prove to client that mail lost is not caused by your server?
