[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 --

[Dovecot] Problems with sieve

[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

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.

Hi, dovecot's imap process segfaults when I search a virtual mailbox using the fts_squat plugin. Is this supposed to work, or a known bug? I've seen some changes commited to fts_solr a couple of months ago that where supposed to fix search issues on virtual mailboxes, maybe fts_squat needs to be fixed to? log === rawlog ------ 3551 SELECT "INBOX.virtual.unseen" 3552 UID SEARCH TEXT "catalyst" syslog ------ 11:34 kernel: [78583.208983] imap[29376]: segfault at 0 ip 0 sp 7fff9b3e1698 error 14 in imap[400000+f4000] 11:34 dovecot: dovecot: child 29376 (imap) killed with signal 11 (core dumps disabled) backtrace ========= As I'm using Debian's 1.2.1 package, the debugging symbols are stripped.

[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.

[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. Is it possible that the data_has_nuls test doesn't work as intended or that it only works with MIT Kerberos? Thank you. -- John Marshall

[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
